Description

Technical Field

[0001] The invention relates to the field of locks, and in particular to a mechanical transmission mechanism for a glass door lock. Background Art

[0002] In order to avoid damaging the glass door, most of the existing glass door locks are clamped on the glass door by clips, unlike traditional door locks which are mostly fixed to the door by drilling holes in the door. This means that most glass doors themselves are not opened by keys. Most of them are unlocked by fingerprints, buttons or cards. However, in actual practice, if the lock is broken, it may lead to the situation that the door cannot be opened. Since it is non-mechanically unlocked, it can only be unlocked by force, which may cause the door lock to be damaged.

[0003] Therefore, if the traditional key unlocking method can be used on the glass door without causing damage to the glass door, the durability and ease of use of the glass door lock can be greatly improved. Therefore, a glass door lock mechanical transmission mechanism is needed that can bypass the glass door so that the glass door lock can be mechanically unlocked. Summary of the invention

[0004] The main purpose of the present invention is to provide a glass door lock mechanical transmission mechanism which can enable the glass door lock to be mechanically unlocked while bypassing the glass door.

[0005] The present invention proposes a mechanical transmission mechanism for a glass door lock, comprising a transmission member and an inner transmission arm and an outer transmission arm arranged on both sides of the transmission member, wherein the transmission member is arranged on the side of a connecting lock clamp connecting an inner lock body and an outer lock body, the inner transmission arm is connected to an inner lock core in the inner lock body on the inner side of the connecting lock clamp, and the outer transmission arm is connected to an outer lock core in the outer lock body on the outer side of the connecting lock clamp. By using the mechanical transmission mechanism for the glass door lock, a user can rotate the inner lock core or the outer lock core while also synchronously rotating the outer lock core or the inner lock core on the other side through mechanical transmission.

[0006] Preferably, the outer transmission arm comprises an upper transmission arm and a lower transmission arm which are arranged in a mirror image with respect to the midline of the transmission member.

[0007] Preferably, the inner transmission arm and the outer transmission arm are respectively provided with inner transmission arm transmission teeth and outer transmission arm transmission teeth, and the inner transmission arm and the outer transmission arm are respectively connected with the inner lock core and the outer lock core through the inner transmission arm transmission teeth and the outer transmission arm transmission teeth.

[0008] Preferably, a plurality of limit grooves are provided on the inner transmission arm and the outer transmission arm, and a number of limit columns whose sizes are matched with the limit grooves are provided on the connecting lock clamp at positions corresponding to the limit grooves, and the transmission of the mechanical transmission mechanism of the glass door lock is limited by the cooperation between the limit grooves and the limit columns.

[0009] Preferably, a side shielding member capable of hiding the transmission member is provided on the side surface of the connecting lock clamp. By providing the side shielding member, the transmission member can be protected and made more beautiful.

[0010] The beneficial effects of the glass door lock mechanical transmission mechanism of the present invention are:

[0011] By setting up a glass door lock mechanical transmission mechanism, the glass door lock can be mechanically unlocked while bypassing the glass door, so that when the motor is damaged or power is off, the user can also unlock it from the outside, which is convenient for the user.

[0012] By providing an upper transmission arm and a lower transmission arm, it can adapt to both left-opening and right-opening door situations at the same time, and has a wider adaptability.

[0013] The mechanical transmission mechanism of the glass door lock is hidden in the connecting lock clip and cannot be seen from the outside, so it will not affect the overall aesthetics of the glass door lock. It can also effectively protect the mechanical mechanism of the glass door lock mechanical transmission mechanism and avoid damage to the mechanical transmission mechanism of the glass door lock caused by the outside.

[0019] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0020] Reference Figures 1 to 3 , an embodiment of the glass door lock mechanical transmission mechanism of the present invention is proposed:

[0021] A glass door lock mechanical transmission mechanism 1 comprises a transmission member 11 and an inner transmission arm 13 and an outer transmission arm 12 arranged on both sides of the transmission member 11.

[0022] The transmission member 11, the inner transmission arm 13 and the outer transmission arm 12 are integrally formed. The outer transmission arm 12 includes an upper transmission arm 121 and a lower transmission arm 122 which are arranged in a mirror image of the center line of the transmission member 11. The inner transmission arm 13, the upper transmission arm 121 and the lower transmission arm 122 are respectively provided with inner transmission arm transmission teeth 131 and outer transmission arm transmission teeth 123 on the end sides. The inner transmission arm 13, the upper transmission arm 121 and the lower transmission arm 122 are respectively connected with the inner lock core and the outer lock core through the inner transmission arm transmission teeth 131 and the outer transmission arm transmission teeth 123. The reason why the upper transmission arm 121 and the lower transmission arm 122 are provided is that in actual practice, the door can be opened to the right or to the left. For the outer door opened by button unlocking, fingerprint unlocking or card swiping, the up and down direction of the outer lock body cannot be reversed, otherwise it will cause inconvenience to the user. The inner lock body is mostly unlocked by buttons or knobs, and it does not matter if the up and down direction is reversed. Therefore, the upper transmission arm 121 and the lower transmission arm 122 are provided to cope with the situations of left opening and right opening. Regardless of whether it is opened to the left or right, one of the upper transmission arm 121 or the lower transmission arm 122 can always connect with the outer lock core teeth.

[0023] Two limiting grooves 14 are arranged on the inner transmission arm 13, two limiting posts 21 are arranged on the inner side of the connecting lock clamp 2 at positions corresponding to the limiting grooves 14 of the inner transmission arm 13, one limiting groove 14 is arranged on each of the upper transmission arm 121 and the lower transmission arm 122, and two limiting posts 21 are arranged on the outer side of the connecting lock clamp 2 at positions corresponding to the limiting grooves 14 of the outer transmission arm 12. The transmission of the glass door lock mechanical transmission mechanism 1 is limited by the cooperation between the limiting grooves 14 and the limiting posts 21.

[0024] The transmission member 11 is arranged on the side of the connecting lock clip 2 connecting the inner lock body and the outer lock body. A side shielding member capable of hiding the transmission member 11 is arranged on the side of the connecting lock clip 2. By arranging the side shielding member, the transmission member 11 can be protected and the lock body can be made more beautiful.

[0025] In actual use, the designs of the inner lock core and the outer lock core can be varied. Here is a more conventional design. The outer lock core is an outer lock core gear, and the key unlocking device is toothed with the outer lock core gear. The remaining unlocking devices of the outer lock body can be electrically connected to the motor on the inner lock body through wires or wirelessly. The outer lock core gear is toothed with the upper transmission arm 121 or the lower transmission arm 122, and the inner lock core is an inner lock core gear that is respectively toothed with the motor, the inner transmission arm 13 and the knob, and the inner lock core gear is toothed with the lock tongue arranged on the inner lock body.

[0026] The user can use a key on the outside to drive the outer lock core gear to rotate through the key unlocking device, and the outer lock core gear drives the upper transmission arm 121 or the lower transmission arm 122 to move up and down, and the upper transmission arm 121 or the lower transmission arm 122 drives the inner transmission arm 13 to move up and down through the transmission member 11, thereby driving the inner lock core gear to rotate through the inner transmission arm 13, thereby driving the lock tongue to move left and right to complete unlocking or locking. The inner button and the other unlocking devices on the outside are all controlled by the motor, so that the motor drives the inner lock core gear to rotate, thereby driving the lock tongue to move left and right to complete unlocking or locking.

[0027] The beneficial effects of the glass door lock mechanical transmission mechanism of the present invention are:

[0028] By providing the glass door lock mechanical transmission mechanism 1, the glass door lock can be mechanically unlocked while bypassing the glass door, so that when the motor is damaged or the power is cut off, the user can also unlock it from the outside, which is convenient for the user.

[0029] By providing the upper transmission arm 121 and the lower transmission arm 122 , the door can be adapted to both left-opening and right-opening situations, and has a wider adaptability.

[0030] The glass door lock mechanical transmission mechanism 1 is hidden in the connecting lock clamp 2, and the glass door lock mechanical transmission mechanism 1 cannot be seen from the outside, so it will not affect the overall aesthetics of the glass door lock. It can also effectively protect the mechanical structure of the glass door lock mechanical transmission mechanism 1 to avoid damage to the glass door lock mechanical transmission mechanism caused by the outside.

[0031] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
