Description

Guide rail buckle and electrical equipment installation structure

Technical Field

The present invention belongs to the technical field of clips, and more specifically, relates to a guide rail clip and an electrical equipment installation structure.

Background Art

In the industrial field, electrical equipment such as routers and gateway devices need to be fixed to walls or cabinets. Most of the time, guide rails are pre-installed on the wall or cabinet, and then the guide rail clips are fixed on the back of the electrical equipment. The guide rail clips are then installed on the guide rails. Most of the guide rail clips in the prior art are made of elastic materials. When in use, the guide rail clips are directly pressed to deform them and hook them onto the guide rail. However, the guide rail clips of this structure are not strong enough and are inconvenient to disassemble.

In view of this situation, CN212876397U discloses a new type of guide rail buckle, including a buckle fixing block, an upper sliding block, a protective cover, a tension spring, a lower sliding block, a handle, a first connecting rod, a connecting rod and a limit screw. Initially, the tension spring is in a slightly stretched state when installed. Under the influence of the tension of the tension spring, the upper sliding block and the lower sliding block are both at the innermost edge of the upper slide groove or the lower slide groove inside the buckle fixing block. At this time, the opening size S formed by the upper slider and the lower slider is the smallest. When it is needed, the handle is pulled down by hand, and the handle drives the connected lower sliding block to move downward, and the opening size S required to adapt to the adjustment of the guide rail size increases accordingly.

The above-mentioned guide rail buckle uses the handle to pull the spring to make the opening larger for easy installation on the guide rail bar. After the guide rail buckle is put on the guide rail bar, the handle is released to make the spring contract, and the guide rail buckle will be clamped on the guide bar. In order to stably fix the electrical equipment on the guide bar, a large spring force is required to clamp the guide rail buckle on the guide bar. During subsequent disassembly, the staff needs to overcome the large spring force to pull open the handle, which makes the disassembly and assembly of the entire guide rail buckle more difficult.

CN209514154U discloses a guide rail type fiber optic distribution box, comprising a guide rail, a DIN type buckle, a fiber optic distribution box and a protective cover, wherein the guide rail is fixedly mounted on a wall, the DIN type buckle is clamped on the guide rail, a fiber optic distribution box is fixedly arranged on the surface of the DIN type buckle, and a protective cover of the fiber optic distribution box is also arranged on the surface of the DIN type buckle, L-shaped plates are fixedly arranged on both sides of the bottom surface of the guide rail, C-shaped grooves are formed between the L-shaped plates on both sides and the bottom surface of the guide rail, and threaded through holes are respectively opened at both ends of the horizontal plates of the L-shaped plates on both sides of the bottom surface of the guide rail, a fixed clamping block at one end of the bottom surface of the DIN type buckle is fixedly clamped in the C-shaped groove on the upper side of the A guide rail, and a movable clamping block at the other end of the bottom surface of the DIN type buckle is fixedly clamped in the C-shaped groove on the lower side of the B guide rail.

The above-mentioned guide rail type fiber optic distribution box uses screws to tighten the guide rail buckle on the guide rail bar. The screw is rotated to move the screw from bottom to top to push the movable block, and then the opening is contracted to clamp the guide rail bar. However, this method also has inconveniences. When the electrical equipment is large, the back of the equipment will cover the entire guide rail buckle, making it difficult for the staff to rotate the screw, and it is also very inconvenient to disassemble and assemble.

DETAILED DESCRIPTION

The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

Example 1

Referring to FIGS. 1 to 4 , in one embodiment of the present invention, a guide rail buckle comprises a fixed block 1 and a movable block 2, wherein a first slot 11 opening downward is provided on the top of the fixed block 1, wherein the first slot 11 is used to hook the upper end of the external guide rail, and the movable block 2 is rotatably connected to the lower end of the fixed block 1, and a first folded edge 3 bent in a direction close to the external guide rail and a second folded edge 4 bent in a direction away from the external guide rail are provided on one side of the movable block 2, and a third folded edge 5 extending in a direction away from the movable block 2 is provided at the end of the second folded edge 4, and a fastener 6 is detachably mounted on the third folded edge 5;

When in use, the fixed block 1 is fixed on the external electrical equipment and the side thereof away from the first card slot 11 is attached to the external electrical equipment. The first card slot 11 is first hooked onto the external guide rail, and then the movable block 2 is rotated upward, so that the first folded edge 3 is inserted into the back of the lower end of the external guide rail, and the second folded edge 4 is pressed against the lower end of the external guide rail upward, and cooperates to form a second card slot to hook onto the lower end of the external guide rail. At this time, the third folded edge 5 is just above the second folded edge 4, and the fastener 6 is operated to allow the fastener 6 to enter the groove of the external guide rail. In this way, the second folded edge 4 and the fastener 6 clamp the lower end of the external guide rail in the middle, and the movable block 2 cannot be rotated downward, and the guide rail buckle can be stably clamped on the external guide rail. This non-elastic structure does not require much effort during disassembly and assembly; at the same time, the movable block 2 is rotatable, so that the movable block 2 can be rotated out of the back of the external electrical equipment, and the fastener 6 can be operated without being covered by the external electrical equipment, which is more convenient for disassembly and assembly.

Of course, it is also possible to drill a hole on the external guide bar and allow the fastener 6 to extend into the hole, which can also prevent the movable block 2 from rotating downward; as a specific manifestation of this embodiment, the fastener 6 includes a second screw 61, and a threaded hole is provided on the third folded edge 5. The second screw 61 is threadedly connected in the threaded hole. The second screw 61 is rotated to extend into the groove of the external guide bar. The second screw 61 and the second folded edge 4 cooperate to clamp the lower end of the external guide bar in the middle, thereby preventing the movable block 2 from rotating downward. When disassembly is required, the second screw 61 is rotated to remove it, and the movable block 2 can rotate downward.

When the peripheral electrical equipment is relatively large, two guide rail clips may be required. In this case, the movable blocks 2 of the two guide rail clips need to be symmetrical with each other so that they can be rotated upward in opposite directions and fixed to the same peripheral guide rail bar.

In this embodiment, the fixing block 1 is provided with a plurality of countersunk holes, which extend from one side of the fixing block 1 close to the external guide rail to the other side. Screws are passed through the countersunk holes to lock the fixing block 1 to the external electrical equipment, and the screw heads can be hidden.

Preferably, a protrusion 12 is provided at the lower part of one side of the fixed block 1 close to the external guide bar, and the protrusion 12 protrudes in the direction close to the external guide bar and its protrusion height is adapted to the thickness of the external guide bar. The movable block 2 is attached to the protrusion 12, and the movable block 2 will not interfere with the external guide bar when rotating, ensuring that the first folded edge 3 can be inserted into the back side of the lower end of the external guide bar.

Preferably, the bending angle between the first folded edge 3 and the movable block 2 is 135-160°, that is, the first folded edge 3 is the A side, the movable block 2 is the B side, and the angle between the A side and the B side away from the external guide bar is 135-160°, which is convenient for the first folded edge 3 to be inserted into the back side of the lower end of the external guide bar. More preferably, the bending angle between the first folded edge 3 and the movable block 2 is 150°.

Preferably, the bending angle between the second folded edge 4 and the movable block 2 is 90°, so that the second folded edge 4 can cooperate with the first folded edge 3 to form a second slot. In this case, the second folded edge 4 can better press against the lower end of the external guide bar, and the lower end of the external guide bar will not slide along the second folded edge 4, and the stability is better.

In actual use, the first folded edge 3 and the second folded edge 4 are sequentially arranged on the edge of the movable block 2 in a direction away from the center of the rotation circle, so that when the first folded edge 3 is inserted into the back of the lower end of the external guide rail, the positions of the first folded edge 3 and the first card slot 11 are relatively close, so that the entire guide rail buckle can be better buckled on the external guide rail, with better stability and more firm fixation;

Even the first folded edge 3 and the second folded edge 4 can overlap at one position, but this method is not easy to process or the processing cost is high, and it can only be extruded. The staggered arrangement of the first folded edge 3 and the second folded edge 4 can be processed by sheet metal bending, which is cheaper and easier to process.

Specifically, the protrusion 12 is provided with a shaft through hole 13, the movable block 2 is provided with a shaft stud 21, and the movable block 2 is rotatably connected to the shaft through hole 13 through the shaft stud 21; and further includes a first screw 7, the first screw 7 is locked to the shaft stud 21 from the side of the fixed block 1 away from the external guide rail;

Since the outer diameter of the head of the first screw 7 is larger than the diameter of the shaft through hole 13, the first screw 7 cannot pass through the shaft through hole 13, preventing the shaft stud 21 from escaping from the shaft through hole 13; in order to prevent the first screw 7 from affecting the rotation of the shaft stud 21, the length of the shaft stud 21 is greater than the depth of the shaft through hole 13, so that the first screw 7 will not contact the fixing block 1 and will not affect the rotation of the shaft stud 21;

At the same time, the movable block 2 can be set to a parallelogram, and the shaft stud 21 is set at its smaller angle, so that the possibility of interference with the external guide bar during rotation is smaller, and the first folded edge 3 and the second folded edge 4 are respectively set on two side lines on the same side of the movable block 2. When the second folded edge 4 is pressed against the lower end of the external guide bar, a part of the first folded edge 3 can also be inserted into the back side of the lower end of the external guide bar without affecting the fixation.

Preferably, a side of the fixed block 1 away from the external guide bar is provided with a space avoidance groove 14, and the space avoidance groove 14 is open in the direction away from the external guide bar. The shaft through hole 13 is arranged in the space avoidance groove 14, and the head thickness of the first screw 7 is less than the depth of the space avoidance groove 14, so that the head of the first screw 7 can be hidden in the space avoidance groove 14, and will not interfere with the fixed connection between the fixed block 1 and the external electrical equipment.

In this embodiment, the third folded edge 5 is provided with a baffle 8 extending in a direction away from the external guide rail. When the movable block 2 is in a free-falling state, the baffle 8 can be stuck on the edge of the external electrical equipment, so that the movable block 2 will not rotate to the back of the external electrical equipment, and the worker does not need to reach to the back of the external electrical equipment to grab the movable block 2.

Example 2

1 to 6, an electrical equipment installation structure includes an equipment body 9 and a guide rail 10 fixed to an external wall, wherein the equipment body 9 is installed on the guide rail 10 by a guide rail buckle, and the guide rail buckle is as described in Example 1;

The fixed block 1 is fixedly connected to the device body 9 and its side away from the first slot 11 is in contact with the device body 9. The first slot 11 hooks the upper end of the guide bar 10, and the first folded edge 3 and the second folded edge 4 cooperate to form a second slot to hook the lower end of the guide bar 10. The fastener 6 on the third folded edge 5 enters the groove of the guide bar 10. In this way, the second folded edge 4 and the fastener 6 clamp the lower end of the guide bar 10 in the middle, and the movable block 2 cannot rotate downward. The device body 9 can be stably fixed on the guide bar 10. When disassembly is required, the fastener 6 is removed, and the movable block 2 is allowed to rotate downward. The first folded edge 3 and the second folded edge 4 can leave the guide bar 10, and then the fixed block 1 is lifted to make the first slot 11 leave the guide bar 10, and the device body 9 can be disassembled.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
