Description

Technical Field

[0001] This utility model relates to the field of lock body technology, specifically to a reversing mechanism for a lock body latch. Background Technology

[0002] Currently, lock bodies available on the market generally include a lock case, a lock cylinder, and a bolt that protrudes from the lock case. The lock cylinder is equipped with a lever. When the key is inserted into the lock cylinder and the lever is turned, the lever works with the bolt to extend or retract the bolt from the lock case, thereby achieving the purpose of unlocking or locking.

[0003] The opening method of a door (left / right, inward / outward) determines the orientation of the latch bevel. If the orientation is reversed, the latch will hit the door frame and cannot be inserted into the lock hole. For example, outward-opening doors require the latch bevel to face outward, while inward-opening doors require it to face inward. Common locks require the latch to be rotated 180° to change direction. However, the latch is often limited by the lock housing, making it difficult to do directly. Usually, the latch needs to be removed from the lock housing before being rotated 180°, which is very difficult and requires a lot of force, time, and effort. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0028] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Please see Figures 1-5 As shown in the figure, the present invention provides a reversing mechanism for a lock body latch, including a lock body 1, a latch 2 inside the lock body 1, a reversing component 3 on one side of the latch 2, a rotating ring 4 fixedly connected to one side of the latch 2, and an operating groove 5 on one side of the lock body 1.

[0030] The rotating ring 4 is installed on the outside of the reversing assembly 3 inside the lock body 1. The reversing assembly 3 can be easily operated through the cavity of the operating groove 5, thereby rotating the rotating ring 4. When the rotating ring 4 rotates, it drives the oblique locking tongue 2 to rotate, thereby quickly reversing the oblique locking tongue 2. This achieves the effect of reversing the oblique locking tongue 2 without disassembling the lock body 1.

[0031] Preferably, the reversing assembly 3 includes a fixed block 31 disposed on the inner wall of the rotating ring 4, a rotating rod 32 rotatably connected to the inner wall of the fixed block 31, a double-headed cam 33 fixedly connected to the outer side of the rotating rod 32, and a movable plate 34 disposed on both sides of the double-headed cam 33.

[0032] A rod 35 is fixedly connected to one side of the movable plate 34, and a spring 36 is sleeved on the rod 35.

[0033] Both the fixing block 31 and the inner wall of the rotating ring 4 are provided with a pair of insertion holes 37 that are used to cooperate with the insertion rod 35, and the number of insertion holes 37 is set to two.

[0034] Initially, the oblique locking tongue 2 is in the forward position. When it is necessary to change the direction of the oblique locking tongue 2, the double-headed cam 33 is rotated by the rotating rod 32, so that the double-headed cam 33 rotates from the horizontal direction to the vertical direction. The moving plates 34 on both sides of the double-headed cam 33 move towards each other under the elastic force of the spring 36, which drives the two insertion rods 35 to move towards each other, so that the insertion rods 35 are separated from the insertion holes 37. At this time, the oblique locking tongue 2 can be moved to the reverse position. The oblique locking tongue 2 simultaneously drives the rotating ring 4 to rotate outside the fixed block 31, so that the other two sets of insertion holes 37 correspond to the insertion rods 35. Then, the rotating rod 32 is rotated again to make the double-headed cam 33 drive the insertion rods 35 to re-insert into the insertion holes 37, and the oblique locking tongue 2 in the reverse position is positioned and fixed.

[0035] Preferably, a rotating block 6 is fixedly connected to the top of the rotating rod 32, and a handle groove 7 is provided inside the lock body 1.

[0036] The rotating block 6 on the top of the fixed block 31 facilitates the rotation of the rotating rod 32, and the handle groove 7 facilitates the connection between the handle and the lock body 1.

[0037] Preferably, a mounting plate 8 is fixedly connected to one side of the lock body 1. The mounting plate 8 has multiple mounting holes 9 inside, so that the lock body 1 can be easily installed on the door through the mounting plate 8 and the mounting holes 9.

[0038] The working principle of this utility model is as follows: In the initial state, the oblique locking tongue 2 is in the forward position. When it is necessary to change the direction of the oblique locking tongue 2, the double-headed cam 33 is rotated by the rotating rod 32, so that the double-headed cam 33 rotates from the horizontal direction to the vertical direction. The moving plates 34 on both sides of the double-headed cam 33 move towards each other under the elastic force of the spring 36, which drives the two insertion rods 35 to move towards each other, so that the insertion rods 35 are separated from the insertion holes 37. At this time, the oblique locking tongue 2 can be moved to the reverse position. The oblique locking tongue 2 drives the rotating ring 4 to rotate outside the fixed block 31, so that the other two sets of insertion holes 37 correspond to the insertion rods 35. Then, the rotating rod 32 is rotated again to make the double-headed cam 33 drive the insertion rods 35 to re-insert into the insertion holes 37, and the oblique locking tongue 2 in the reverse position is positioned and fixed, so that the oblique locking tongue 2 can be changed without disassembling the lock body 1.

[0039] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
