Description
Technical Field
[0001] This utility model relates to the field of lock technology, specifically to a button-type anti-peeping smart lock. Background Technology
[0002] A security door is a door equipped with a security lock that can resist unauthorized opening under certain conditions for a certain period of time, possesses a certain level of security protection, and meets the corresponding security level.
[0003] Most security doors using anti-theft locks have peepholes. Some technicians can use special tools to open the door by pressing down the handle inside the door through the peephole, but this is not ideal.
[0004] Interior door handles are usually directly linked to the lock body's opening mechanism. When a tool is inserted through the peephole and the interior handle is pressed down, the force applied to the handle is directly transmitted to the lock body's transmission mechanism, causing the bolt to retract and the door to open.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0026] like Figure 1-3 As shown, the present invention proposes a button-type anti-peeping smart lock, which includes a panel 1, a bearing 2 provided at the opening of the panel 1, and a bearing pressure plate 3 for limiting the position on one side of the bearing 2.
[0027] The handle mechanism includes a handle 41 mounted on one side of the bearing 2, a handle reset shaft seat 42 sleeved inside the handle 41, and a handle reset torsion spring 43 for reset mounted on the handle reset shaft seat 42. The handle 41 and the handle reset shaft seat 42 rotate with the bearing 2.
[0028] The freeing mechanism includes a free square steel 51 that passes through the handle 41 and the handle return shaft seat 42. A free square steel return spring 52 is sleeved on the outside of the free square steel 51. One end of the free square steel return spring 52 is attached to the handle 41, and the other end is connected to a flat pad 53. The flat pad 53 is sleeved on the outer wall of the free square steel 51, and a retaining ring 54 is provided on one side of it.
[0029] The tail of the free square steel 51 is connected to an anti-peeping button 55 that moves along the inner cavity of the handle 41, and a free sleeve 56 is provided on one side of the free square steel 51 and fitted into the inner cavity of the handle reset shaft seat 42.
[0030] It should be noted that the handle reset shaft seat 42 and the free sleeve 56 are separate structures; the handle reset shaft seat 42 and the free sleeve 56 are two independent parts, and under normal conditions they are in a separated state.
[0031] The free sleeve 56 has a slot that matches the free square steel 51. When the free square steel 51 is inserted into the free sleeve 56, the two are connected to form a combined structure. The end of the free sleeve 56 has a slot that matches the square segment of the free square steel 51. When the anti-peeping button 55 is pressed, the square segment is inserted into the slot to combine. The rotational force is directly transmitted through the square segment and the slot to achieve synchronous movement and prevent slippage.
[0032] In this embodiment, a freeing mechanism is provided, which includes a normal state and a usage state;
[0033] Under normal conditions, the square section of the free square steel 51 separates from the free sleeve 56 under the elastic force of the free square steel return spring 52. The rotatable part consisting of the handle 41, the handle return shaft seat 42 and the free square steel 51 is separated from the lock body transmission part that cooperates with the free sleeve 56. The handle 41 cannot drive the lock body when rotated.
[0034] When in use, the user presses the anti-peeping button 55, pushing the free square steel 51 into the free sleeve 56. At this time, the free square steel return spring 52 deforms under pressure until the square section of the free square steel 51 enters the free sleeve 56. At this time, the rotatable part and the lock body transmission part that cooperates with the free sleeve 56 are in an integrated state. The force of rotating the handle 41 is transmitted through the handle return shaft seat 42, which drives the lock body transmission part that cooperates with the free sleeve 56 to move, thereby unlocking.
[0035] It should be added that: after the unlocking is completed, because the anti-peeping button 55 is not pressed, the square steel return spring 52, under its own reset performance, drives the free square steel 51 back to the initial position, and the anti-peeping button 55 pops out.
[0036] The handle 41 and the handle reset shaft seat 42 spring back to their initial positions under the reset performance of the handle reset torsion spring 43;
[0037] After use, the linkage between the handle 41 and the anti-peeping button 55 is restored to its initial normal state.
[0038] In order to utilize the pressure deformation characteristics of the free square steel return spring 52, the free square steel return spring 52 clamped between the flat pad 53 and the handle 41 is a deformation component. The retaining ring 54 on the other side of the flat pad 53 is fixedly installed in the slot of the free square steel 51, ensuring that the flat pad 53, retaining ring 4 and free square steel 51 move inward or outward as a whole, and the free square steel 51 can quickly return to its initial position after the anti-peep button 55 is released.
[0039] It is understandable that when the anti-peeping button 55 moves along the inner cavity of the handle 41, the free square steel return spring 52 is in a compressed state. The greater the pressure applied to the anti-peeping button 55, the greater the elastic potential energy stored in the free square steel return spring 52 under compression.
[0040] To further enhance the aesthetics and protective effect of the anti-peeping button 55, a handle decorative cover 6 mounted on the handle 41 is provided on the outer side of the anti-peeping button 55.
[0041] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
