Description

Fixing assembly

Technical Field

The present invention relates to a fixing assembly, and more particularly, to a fixing assembly including a sliding fastener.

Background

With the development and progress of technology, electronic devices (e.g., computers, servers, etc.) have become an indispensable necessity in people's daily life. In terms of a server, the server usually has electronic components such as a motherboard, a central processing unit, a hard disk, a memory, and a fan, and these electronic components are all installed in a housing.

In the case of a server fan, the fan is usually first installed in a fan bracket, and then the fan bracket with the fan is installed in the server housing. Generally, the fan bracket is installed in the housing by hooking or abutting against the assembly member on the housing during the rotation of the arc groove of the rotating member of the fan bracket, so that the entire fan bracket is lowered or raised, and the fan is connected to or disconnected from the electrical connector on the housing. In order to prevent the integral fan bracket from rotating when the rotating member is rotated, a user needs to support the fan bracket by hand or a positioning column must be additionally arranged on the casing to limit the rotation of the fan bracket. In the method of limiting the rotation of the fan bracket by hand, the rotating member is rotated while the fan bracket is supported by the other hand, which is inconvenient for the user to fix or separate the fan bracket to or from the housing. In addition, in the way that the positioning posts limit the rotation of the fan bracket, the fan bracket may be separated from the positioning posts during the rotation of the rotating member, so that the user still has to prevent the fan bracket from rotating by hand, which is still inconvenient for the user to fix or separate the fan bracket to or from the housing.

Disclosure of Invention

The present invention provides a fixing assembly to solve the problem that a fan bracket is not fixed to or separated from a housing due to the rotation of a rotating member during the rotation of the rotating member in the prior art.

The fixing assembly disclosed by the embodiment of the invention is suitable for fixing a frame body. The fixing component comprises a first assembly part, a second assembly part and a fastener. The first assembly part comprises a vertical plate and a transverse plate which are connected. The transverse plate comprises a clamping groove, and the clamping groove comprises a clamping section and a reducing section which are connected. The width of the tapered section is gradually reduced from one side of the connecting buckle section to the direction far away from the buckle section. The second assembly part is used for being fixed on the frame body, and part of the second assembly part is located above the transverse plate. The fastener comprises a sliding part and a fastening part. The sliding part is slidably arranged on the second assembly. The buckling part is fixed on the sliding part and protrudes out of one side of the second assembly part, and the buckling part comprises a guide inclined plane. The fastener can slide between a fastening position and a disengaging position. When the buckling piece is located at the buckling position, the buckling part is located at the buckling section and is buckled on the transverse plate. When the buckling piece moves from the buckling position to the disengaging position, the buckling part moves from the buckling section to the reducing section so that the transverse plate abuts against the guide inclined surface of the buckling part and the buckling part is disengaged from the buckling groove.

According to the fixing assembly disclosed in the above embodiment, the fastening member is slidable relative to the second assembly member, and the tapered section of the guide slope and the fastening groove are matched, so that the frame body can only move up and down in the process that the sliding fastening member fixes or separates the second assembly member and the frame body to or from the first assembly member, and the frame body cannot move along the sliding direction of the fastening member. Therefore, the convenience of the frame body and the second assembly part assembled and disassembled on the first assembly part is improved.

The above description of the present invention and the following description of the embodiments are provided to illustrate and explain the spirit and principles of the present invention and to provide further explanation of the invention as claimed in the appended claims.

The sidewall surface 124 surrounds the catch groove 123. In the present embodiment, the slope of the portion of the sidewall surface 124 corresponding to the tapered section 1232 varies in different cross-sections. In detail, the partial side wall surface 124 corresponding to the tapered section 1232 is inclined to an increasing extent from the side connecting the buckle section 1231 toward a direction away from the buckle section 1231. Further, a normal line of the partial side wall surface 124 faces a direction away from the second side edge 112. The term "away" as used herein means away from the second side edge 112 in the vertical direction. That is, when the second side edges 112 of the risers 11 are near the bottom of the server casing, the side wall surfaces 124 are facing the top of the server casing. The first snap structure 125 is, for example, a flange. The first snap feature 125 is connected to the sidewall surface 124 and located at the snap section 1231 of the snap groove 123.

Please refer to fig. 2 and fig. 4. Fig. 4 is a cross-sectional view of fig. 2.

The second assembly 20 includes a base 21, a first sidewall 22, a second sidewall 23 and a third sidewall 24. The base 21 is fixed to one side of the frame 3, and the frame 3 is used to accommodate a fan, for example. The second side wall portion 23 and the third side wall portion 24 are respectively connected to two opposite sides of the first side wall portion 22, and the first side wall portion 22, the second side wall portion 23 and the third side wall portion 24 are respectively connected to two opposite sides of the base portion 21. The first sidewall portion 22 faces the riser 11 and the first face 121 of the cross plate 12 faces a portion of the base 21. That is, part of the second assembly 20 is located above the cross plate 12 and on the side of the cross plate 12 away from the second side edge 112 of the riser 11. The first sidewall portion 22, the second sidewall portion 23, the third sidewall portion 24 and the base portion 21 form an accommodating space 25. The base portion 21 includes a through hole 211, and the first sidewall portion 22 includes a sliding slot 221. The through hole 211 and the sliding groove 221 are communicated with the accommodating space 25 and located at two adjacent sides of the accommodating space 25, and the through hole 211 corresponds to the fastening groove 123. Two guide posts 30 are disposed on the side of the first sidewall 22 facing the riser 11, and the two guide posts 30 are slidably disposed in the two guide slots 113.

The locking member 40 includes a sliding portion 41, a locking portion 42 and a rivet portion 43. The sliding part 41 includes a base 411 and two handles 412. The fastening portion 42 is fixed to one side of the base 411 by the rivet plate portion 43, and the two handles 412 are respectively connected to the other two opposite sides of the base 411. The base 411 is slidably disposed in the accommodating space 25, the two handles 412 are disposed outside the accommodating space 25, and the fastening portion 42 passes through the through hole 211 and protrudes out of the base 21. The base 411 includes a lateral surface 4111 and a hook 4112. The side surface 4111 faces the first sidewall 22, and the hook 4112 protrudes from the side surface 4111. The hook 4112 is slidably disposed in the sliding groove 221 and hooks the first sidewall 22. The fastening portion 42 includes a guiding slope 421 and a second fastening structure 422. The second latching structure 422 is, for example, a groove, and the second latching structure 422 is recessed from the guiding inclined surface 421.

In the present embodiment, the locking member 40 can slide between a locking position and a releasing position relative to the second assembly 20 through the sliding portion 41.

When the locking member 40 is located at the locking position, the locking portion 42 of the locking member 40 is disposed through the locking section 1231 (as shown in fig. 3), and the second locking structure 422 is locked to the first locking structure 125, so that the locking portion 42 is locked to the horizontal plate 12. At this time, since the hook portion 42 of the hook 40 and the transverse plate 12 are engaged with each other, the movement of the frame body 3 (shown in fig. 2) in the direction of the normal N of the first surface 121 of the transverse plate 12 is restricted. Therefore, the rack 3 can be firmly fixed on the side plate 2 of the server housing.

Next, referring to fig. 5 and 6, fig. 5 is a cross-sectional view of the second locking structure of the locking portion of fig. 4 separated from the first locking structure. Fig. 6 is a cross-sectional view of the button portion of fig. 5 disengaged from the button slot.

When a user wants to separate the rack 3 (as shown in fig. 2) from the side plate 2 of the server casing, the user can apply a force to the two handles 412 of the locking element 40 by hand, so that the locking element 40 moves toward the second side wall portion 23 along the direction D. During the movement of the locking member 40, the locking portion 42 of the locking member 40 moves from the locking section 1231 to the tapered section 1232, so that the second locking structure 422 is released from the first locking structure 125. Then, the inclined guide surface 421 of the buckle portion 42 presses against a portion of the sidewall surface 124 (as shown in fig. 3) corresponding to the tapered section 1232, so that the buckle portion 42 is guided by the sidewall surface 124, and the buckle portion 42 is separated from the buckle groove 123 along the normal N of the first surface 121 of the transverse plate 12. At this time, the locking member 40 is located at the separating position, and the entire second assembly 20 and the frame body 3 are lifted relative to the first assembly 10, so that the user can pull up the second assembly 20 and the frame body 3 to separate the frame body 3 from the side plate 2 of the server casing.

Conversely, when the rack 3 is to be fixed to the side plate 2 of the server casing, the locking member 40 is first located at the disengagement position, and then the two guide posts 30 are slid into the two guide slots 113, respectively. At this time, the two handles 412 are applied with force in the direction D, so that the fastening portion 42 of the fastening element 40 is guided by the portion of the sidewall surface 124 corresponding to the tapered section 1232, and the fastening portion 42 is disposed through the fastening groove 123, so that the entire second assembly 20 and the frame body 3 sink. Then, the second fastening structure 422 is fastened to the first fastening structure 125, so as to complete the fixing of the rack 3 to the side plate 2 of the server casing.

In the present embodiment, the locking element 40 is slidable relative to the second assembly 20, and the inclined guide surface 421 and the tapered section 1232 of the locking groove 123 cooperate with each other, so that when the sliding locking element 40 fixes or separates the second assembly 20 and the frame 3 to or from the first assembly 10, only the frame 3 is moved up and down, and the frame 3 is not moved along the sliding direction of the locking element 40. Therefore, the convenience of the frame body 3 and the second assembly member 20 being disassembled from the first assembly member 10 is improved.

In addition, the two guide posts 30 and the two guide grooves 113 are matched, so that the second assembly member 20 and the frame body 3 can be further limited to move only in the extending direction of the guide grooves 113, that is, the second assembly member 20 and the frame body 3 can only move up and down, and the probability that the second assembly member 20 and the frame body 3 can move along the sliding direction of the fastener 40 can be reduced.

In the present embodiment, the number of the guide posts 30 and the guide slots 113 is two, but not limited thereto. In other embodiments, the number of the guide posts and the guide slots may be one or more than two.

In addition, the design that the inclination degree of the partial side wall surface 124 corresponding to the tapered section 1232 is gradually increased from the side connected to the fastening section 1231 toward the direction away from the fastening section 1231 can help the guiding fastening portion 42 to be separated from or penetrate the fastening groove 123 during the moving process of the fastening member 40, so as to increase the smoothness of the up-and-down movement of the second assembly 20 and the frame 3.

In the present embodiment, the inclination degree of the partial sidewall surface 124 corresponding to the tapered section 1232 is gradually increased from the side connecting the fastening section 1231 to the direction away from the fastening section 1231, which is not intended to limit the invention. In other embodiments, the partial side wall faces of the tapered sections corresponding to the portions may maintain the same degree of inclination from the side where the snap sections are connected toward the direction away from the snap sections.

In addition, the normal of part of the sidewall surface 124 faces the direction away from the second side edge 112, which is not intended to limit the present invention. In other embodiments, the normals of the overall sidewall surfaces may all face away from the second side edge 112. Further alternatively, the normal to the integral sidewall surface may be perpendicular to the normal to the first surface of the cross plate. That is, the entire side wall surface is a vertical surface.

In the present embodiment, the fixing assembly 1 is disposed between one of the side plates 2 and one of the sides of the frame 3 of the server casing for example, but not limited thereto. In other embodiments, the fixing component may also be disposed between another side plate of the server housing and another side of the rack body.

In addition, the matching of the two guide posts and the two guide grooves can further limit the second assembly part and the frame body to move only in the extending direction of the guide grooves, namely the second assembly part and the frame body can only move up and down, so that the probability that the second assembly frame and the frame body can move along the sliding direction of the fastener can be reduced.

The design that the inclination degree of partial side wall surfaces corresponding to the gradually-reduced section is gradually increased from one side of the connecting buckle section to the direction far away from the buckle section can help the guiding buckle part to be separated from or penetrate through the buckle groove in the moving process of the buckle piece, so that the smoothness of the up-and-down movement of the second assembly piece and the frame body is increased.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
