Description

Technical Field

[0001] This utility model belongs to the field of magnetic locks and relates to a silent magnetic latch. Technical Background

[0002] Traditional magnetic locks rely on the magnetic attraction of the bolt. Without sufficient magnetic force, the bolt cannot be pulled out of the lock case. Therefore, existing magnetic locks have relatively strong magnetic force, generating a large amount of kinetic energy. Consequently, when the bolt extends and touches the lock case, it produces a loud noise. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a silent magnetic latch. This device has the advantages of simple structure and effectively reducing the sound of contact between the latch and the latch box without affecting the magnetic attraction force.

[0004] The objective of this invention is achieved as follows:

[0005] A silent magnetic latch includes a latch plate, a latch shell fixed to the front end of the latch plate, an installation cavity inside the latch shell, and a magnetic suction element disposed inside the installation cavity; the front end of the latch shell is provided with at least one buffer pad.

[0006] By setting a buffer pad at the front end of the latch shell, the contact noise when the latch and the snap box come into contact can be effectively reduced without affecting the magnetic attraction.

[0007] The present invention is further configured such that: the buffer pad is a single pad, which is disposed at the front middle of the locking tongue shell.

[0008] The present invention is further configured such that: the front end of the latch shell has an opening formed in the middle, and the buffer pad includes a fixing part and a buffer part, the fixing part is fixed inside the latch shell, and the buffer part extends out from the opening.

[0009] The above structure allows for better fixation of the cushioning pad.

[0010] The present invention is further configured such that: the front end of the locking tongue plate is provided with a connecting part, the magnetic suction member abuts against the front end of the connecting part, and the fixing part of the buffer pad is sandwiched between the front end of the magnetic suction member and the inner wall of the front end of the locking tongue shell.

[0011] The above structure allows the magnetic components and buffer pads to be stably fixed inside the lock tongue shell, and makes more efficient use of space.

[0012] The present invention is further configured such that: two positioning posts are formed on the inner wall of the front end of the locking tongue shell, the positioning posts are respectively arranged on both sides of the opening, and two positioning holes are formed on both sides of the fixing part to match the two positioning posts respectively.

[0013] The design of the positioning pin makes the fixing part more stable inside the lock tongue shell, making it less likely to slide up and down, thus ensuring the stability of the structure.

[0014] The present invention is further configured such that: the two sides of the connecting part are formed with locking blocks, and the two sides of the locking tongue shell are formed with locking grooves, and the locking blocks are fixed in the locking grooves to achieve detachable fixing.

[0015] The design of the slot and the block allows for the detachable fixing of the lock tongue shell, making it convenient to replace and repair the magnetic parts or the buffer pad.

[0016] The present invention is further configured such that: there are two buffer pads, which are respectively disposed on the upper and lower sides of the front end of the lock tongue shell; the front end of the lock tongue shell has two openings respectively corresponding to the two buffer pads; the buffer pad includes a fixing part and a buffering part; the fixing part is fixed inside the lock head, and the buffering part extends out from the opening.

[0017] By setting two buffer pads on the upper and lower sides of the front end of the latch shell, the latch can more stably contact the buffer pads first when it touches the latch box, resulting in a more stable silent effect.

[0018] The present invention is further configured such that the upper and lower ends of the head shell are recessed inward to form guide grooves.

[0019] By designing guide grooves, guide rails that match the guide grooves are set inside the latch box, thereby guiding the movement of the latch and making the movement of the latch more stable.

[0020] The present invention is further configured such that the magnetic attractant is an iron block or a magnet.

[0021] If the magnetic component is an iron block, then install a magnet inside the snap box; if the magnetic component is a magnet, then install an iron block inside the snap box (mutually attracting magnets are also acceptable).

[0022] The present invention is further configured such that the buffer pad is a rubber pad.

[0023] The outstanding and beneficial technical effect of this invention compared with the prior art is that by setting a buffer pad at the front end of the locking tongue shell, the contact noise when the locking tongue and the buckle box come into contact can be effectively reduced without affecting the magnetic attraction.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0032] Example 1: A silent magnetic latch includes a latch plate 1, a latch shell 2 fixed to the front end of the latch plate 1, a mounting cavity inside the latch shell 2, and a magnetic component 3 disposed inside the mounting cavity; the front end of the latch shell 2 is provided with at least one buffer pad 4. By providing a buffer pad 4 at the front end of the latch shell 2, the contact noise when the latch and the latch box come into contact can be effectively reduced without affecting the magnetic attraction force.

[0033] The buffer pad 4 is a single unit, located at the front center of the latch shell 2.

[0034] The latch shell 2 has an opening 5 formed in the middle of its front end. The buffer pad 4 includes a fixing part 6 and a buffer part 7. The fixing part 6 is fixed inside the latch shell 2, and the buffer part 7 extends out from the opening 5. This structure allows for better fixation of the buffer pad 4.

[0035] The front end of the latch plate 1 is provided with a connecting part 8, the magnetic member 3 abuts against the front end of the connecting part 8, and the fixing part 6 of the buffer pad 4 is sandwiched between the front end of the magnetic member 3 and the inner wall 9 of the front end of the latch shell. Through the above structure, both the magnetic member 3 and the buffer pad 4 can be stably fixed in the latch shell 2, and the space utilization is more reasonable.

[0036] Two positioning posts 10 are formed on the inner wall 9 of the front end of the latch shell. The positioning posts 10 are respectively located on both sides of the opening 5. Two positioning holes 11 are formed on both sides of the fixing part 6, which are respectively matched with the two positioning posts 10. The design of the positioning posts 10 makes the fixing part 6 more stable inside the latch shell 2, and it is not easy to slide up and down, thereby ensuring the stability of the structure.

[0037] The connecting part 8 has locking blocks 12 formed on both sides, and the locking tongue shell has locking grooves 13 formed on both sides. The locking blocks 12 are fixed in the locking grooves 13 to achieve detachable fixation. Through the design of the locking grooves 13 and locking blocks 12, the locking tongue shell 2 can be detachably fixed, which facilitates the replacement and maintenance of the magnetic suction part 3 or the buffer pad 4.

[0038] The upper and lower ends of the latch shell 2 are recessed inward to form guide grooves 14. Through the design of the guide grooves 14, a guide rail matching the guide grooves 14 is set in the latch box, thereby guiding the movement of the latch and making the movement of the latch more stable.

[0039] The magnetic component 3 is an iron block or a magnet. If the magnetic component is an iron block, a magnet is installed inside the snap box; if the magnetic component is a magnet, an iron block (mutually attracting magnets) is installed inside the snap box.

[0040] The buffer pad 4 is a rubber pad.

[0041] Example 2: This example is largely the same as Example 1, except that there are two buffer pads 4, respectively located on the upper and lower sides of the front end of the latch shell 2. The front end of the latch shell 2 has two openings 5 ​​corresponding to the two buffer pads 4. Each buffer pad 4 includes a fixing part 6 and a buffering part 7. The fixing part 6 is fixed inside the latch head 2, and the buffering part 7 extends from the opening. The two fixing parts 6 are integrated into one piece. By placing the two buffer pads on the upper and lower sides of the front end of the latch shell, the latch can more stably contact the buffer pads first when it touches the latch box, resulting in a more stable noise reduction effect.

[0042] This invention features a simple structure and effectively reduces the sound of contact between the latch and the latch box without affecting the magnetic attraction.

[0043] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
