Description

Lock collar structure

The present invention relates to a collar structure of a lock, and more particularly to a collar structure which is connected between a handle and a sleeve.

Press, the handle is for the user to hold, in order to facilitate the movement or manipulation of the object, so it is seen in various fields, especially for items with open and closed type (such as: doors, drawers, etc.) Regardless of whether the handle is a fixed arrangement or a movable arrangement with a transmission mechanism, the connection between the handle and the object is usually provided with a sleeve to shield and protect the aforementioned connection or its transmission mechanism, thereby preventing the handle from being easy to handle. It can be detached or invaded by foreign objects, causing damage to its joints or transmission mechanism and losing its anti-theft property. The set can also achieve decorative effects.

However, the conventional handle is usually provided with a connecting shaft, and the set is provided with a connecting hole corresponding to the connecting shaft, so that the set can be positioned on the object, and the connecting shaft of the handle can be assembled to the object or set by the connecting hole. The transmission mechanism inside the object; however, the setting form of the handle will vary depending on the application or decoration, resulting in different outer diameter dimensions of the connecting shaft. Therefore, if the handle with a small outer diameter of the connecting shaft is used, the connection will be made. There is a great gap between the hole and the connecting shaft. In addition to affecting the aesthetic appearance, it will also expose the connection between the connecting shaft and the object or its transmission mechanism, so that the sleeve loses the protection effect, so the manufacturer must separately create a different difference. The sleeves are connected to the aperture to accommodate assembly of the outer diameter dimensions of the various connecting shafts, which will result in increased development, mold opening, manufacturing, inventory, time and money costs.

Furthermore, in order to further prevent foreign matter from invading, the sleeve is generally axially provided with a convex portion at the periphery of the connecting hole, so that the convex portion can partially block the connection when the connecting shaft is worn in the connecting hole. Axis, and it can be known that if the length of the convex portion is longer, the larger the area covering the connecting shaft, the higher the protective ability will be; in fact, due to the limitation of the process, the set is extremely difficult to directly The convex portion having a long length is formed, and the manufacturing cost is high and the yield is low, which is disadvantageous for the manufacturer to manufacture.

In view of this, the creator specially researched and improved the assembly and protection of the handles, and improved the above problems with a better creation, and after a long period of research and development and continuous testing, the creation of this creation began.

In order to achieve the above objectives, the creator of the present invention provides a collar structure for a lock comprising: a set of discs provided with a perforation; and a set of rings arranged axially. And a convex ring portion correspondingly disposed on the through hole and protruding from the sleeve; and a handle provided with a pivoting portion, the pivoting portion being assembled to the through hole.

According to the collar structure of the lock described above, the corresponding contour of the perforation and the convex ring portion is a circle, a triangle, a square, a polygon or a geometric shape.

According to the collar structure of the lock described above, the sleeve has a first side, and the through hole is retracted to form a stop portion on the first side, and the collar is further provided with an abutting portion. The outer diameter of the crotch portion is larger than the convex ring portion, and the abutting portion is provided with a stop surface corresponding to the top portion.

According to the collar structure of the lock device, the first side of the sleeve is extended with a corresponding ring provided on the through hole, and the convex ring portion protrudes from the tenon.

The collar structure of the lock according to the above aspect, wherein the sleeve has a second side opposite to the first side, and the second side is provided with a groove, the groove is provided on the wall surface of the recessed direction perforation.

According to the collar structure of the lock described above, the collar is coupled to the perforation by riveting, splicing, stamping, bonding or tight fitting.

The collar structure of the lock according to the above, wherein the collar is further retracted at the end of the collar portion to form a receiving portion, and the receiving portion forms a coupling hole corresponding to the through hole, and the handle is The pivoting portion is disposed to the set through the set of holes and the through hole.

According to the above-mentioned collar structure of the lock, the pivoting portion penetrates through a set of holes in the axial direction thereof, and the sleeve hole is further provided with a lock core through which the lock core is connected to a transmission mechanism.

According to the collar structure of the lock described above, the pivoting portion is radially provided with a combined hole, and the protruding ring portion is radially provided with a through hole corresponding to the combined hole.

It is from the above description and settings that it is obvious that this creation has the following several advantages and functions, which are detailed as follows:

1. The creation of the collar can set a pivoting portion smaller than the perforation of the sleeve, so that the sleeve can be equipped with handles of different outer diameters of the pivotal joint to facilitate modular setting, and It can reduce the cost of replacement, manufacturing the set and its inventory cost.

2. The collar of the present invention has a convex ring portion protruding from the sleeve, so as to shield and prevent foreign matter from invading the pivoting portion, the lock core and the transmission mechanism, thereby affecting the function of turning or locking the handle, and improving the overall decoration. Sexuality and aesthetics; in addition, since the collar is separately manufactured, the convex ring portion can be easily formed, so that the convex elongation of the convex ring portion is not easily restricted by the process, so that the relevant manufacturer can form the convex ring according to the use or design requirements. The convexity of the part to enhance the applicability of the whole creation.
