DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the implementation modes and the accompanying drawings. Here, the illustrative implementation modes and descriptions of the present application are used to explain the present application, but are not intended to limit the present application.

[0024] refer to Figures 1 to 7 ,like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a door handle lock, including at least one handle panel 100 and a lock body 200, a handle 120 is provided on the panel body 110 of the handle panel 100, and a mounting groove 111 is provided on the outer surface of the panel body 110, and the handle 120 is hingedly installed in the mounting groove 111 by a rotating shaft parallel to the panel body 110, and the handle 120 is hidden in the mounting groove 111 when resetting, and an elastic reset member is provided between the handle 120 and the panel body 110, and the lock body 200 includes a lock box 220 and a sliding A lock tongue 210 installed on a lock box 220 is provided with at least one guide groove 21, and a through groove corresponding to the position of the guide groove 21 is provided on the side wall of the lock box 220. A shift block 121 is provided on the inner side surface of the handle 120 close to the panel body 110. The shift block 121 passes through the through groove and is inserted into the corresponding guide groove 21. The swinging action of the handle 120 is utilized to drive the lock tongue 210 to be linked, wherein a card slot is provided on the bottom surface of the installation slot 111 for the shift block 121 to pass through and move.

[0025] Specifically, the elastic reset member is preferably a torsion spring. Since the shift block 121 is inserted into the guide groove 21, the guide groove 21 is closed on all sides. When the shift block 121 swings, the shift block 121 and the inner wall of the guide groove 21 are abutted to achieve linkage. At the same time, the swing amplitude of the shift block 121 can be used to limit the inward and outward limit positions of the lock tongue 210, so that there is no need to set a limiting structure for limiting the front and rear positions of the lock tongue 210 in the lock body 200. The automatic reset of the handle 120 can drive the lock tongue 210 to automatically reset, so that there is no need to set an elastic reset structure acting on the lock tongue 210 in the lock body 200, thereby further simplifying the structure in the lock body 200, and directly acting on the lower lock tongue 210 by the shift block 121 directly connected to the handle 120, thereby simplifying the transmission structure between the lock tongue 210 and the handle 120, so that the structure of the door handle lock is further simplified, thereby reducing the probability of failure, and making the present application more durable.

[0026] In an embodiment of the present application, a locking member 230 is further provided in the lock box 220 and is slidably arranged perpendicular to the sliding direction of the lock tongue 210. The locking member 230 can be used to prevent the lock tongue 210 from retracting and retreating to achieve reverse locking. The locking member 230 is driven by the lock core 300 to slide upward and / or downward. When the lock core 300 can only drive the locking member 230 to move in one direction, it is necessary to set an elastic reset member acting on the locking member 230 in the lock box 220.

[0027] like Figure 4 , Figure 5 and Figure 6 As shown, the lock tongue 210 includes a lock tongue core 2, and a cover 1 is sleeved on the locking end of the lock tongue core 2. The above structure allows the lock tongue core 2 and the cover 1 to be made of different materials, and the cover 1 can be made of a high-strength, non-corrosive metal material, which can reduce production costs.

[0028] In the embodiment of the present application, at least one elastic clamping arm 23 is provided on the locking end, and a clamping groove 11 is provided on the side of the cover shell 1 to be clamped and connected with the elastic clamping arm 23. The bolt core 2 and the cover shell 1 are connected together by the clamping connection between the elastic clamping arm 23 and the clamping groove 11, so that the bolt core 2 and the cover shell 1 can be easily replaced separately.

[0029] In the embodiments of the present application, Figure 7 As shown, a groove 22 corresponding to the position of the elastic clamp arm 23 is provided on the locking end, and the elastic clamp arm 23 is located in the groove 22. The provision of the groove 22 can, on the one hand, avoid increasing the thickness of the lock tongue core 2, thereby increasing the thickness of the lock body 200; on the other hand, it can avoid insufficient strength caused by the reduction in the thickness of the lock tongue core 2, so that the strength of the lock tongue core 2 can meet the use requirements.

[0030] In the embodiment of the present application, the cover 1 is connected to the lock tongue core 2 as a whole through a pin shaft. The pin shaft penetrates the cover 1 and the lock tongue core 2, so that the cover 1 and the lock tongue core 2 are connected reliably and stably without shaking.

[0031] Specifically, the cover shell 1 is connected to the lock tongue core 2 as a whole through at least two pins, and the lock tongue core 2 and the cover shell 1 are both provided with a pin hole 25 penetrating along the thickness direction.

[0032] When the cover 1 is detachable, in the embodiment of the present application, preferably, the bolt core 2 has a shoulder portion 24 that abuts against the open end surface of the cover 1. The shoulder portion 24 abuts against the cover 1 to disperse the impact force generated when the bolt 210 collides with the door frame, thereby extending the service life of the pin shaft and / or the elastic clamp arm 23.

[0033] In the embodiment of the present application, at least one limiting seat is provided at the bottom side of the mounting groove 111, and the handle 120 is pressed against the limiting seat when it is reset, and a shock-absorbing block is provided on the end face of the limiting seat that contacts the handle 120. The limiting seat is used to form a channel for finger insertion between the handle 120 and the bottom side of the mounting groove 111, so that the handle 120 is easy to operate, and the support of the limiting seat can ensure that after the handle 120 is automatically reset, the outer side surface of the handle 120 and the outer side surface of the panel body 110 are in the same plane, so that the handle 120 is well hidden in the mounting groove 111, and the handle 120 is prevented from protruding from the outer side surface of the lock plate, thereby improving the safety performance of the handle lock. The provision of the shock-absorbing block reduces the noise generated by the collision between the handle 120 and the limiting seat when the handle 120 is automatically reset, making it comfortable to use, and preventing the limiting seat from being frequently subjected to large impact forces and causing damage.

[0034] When the door handle lock has a handle panel 100, and the lock tongue 210 can be moved backward by using the handle 120 alone, the handle panel 100 is used as an inner handle panel to facilitate quick door opening from indoors.

[0035] In the embodiments of the present application, Figure 5 As shown, when the door handle lock has two handle panels 100, the lock body 200 is located between the two handle panels 100, the lock tongue 210 has two guide grooves 21 offset in the vertical direction, and the handle 120 has a shift block 121, and the two guide grooves 21 cooperate with the corresponding shift blocks 121 of the handle panels 100 respectively.

[0036] Specifically, two guide grooves 211 are provided, and the length direction of the guide grooves 211 is consistent with the moving direction of the lock tongue 210. The crossbeam located between the two guide grooves 211 can be used to improve the strength of the lock tongue 210, so that the lock tongue 210 is not easily deformed. The vertical direction in the present application is the direction consistent with the extension direction of the door height, that is, the two guide grooves 21 are staggered in the upper and lower directions. When it is suitable for use with door leaves of different thicknesses, the two handle panels 100 are within a certain range away from each other, and the shifting block 121 will not separate from the corresponding guide groove 21. It is suitable for use with door bodies of various thickness specifications. Since the handle panel 100 The linkage component is removed to make the thickness of the handle panel 100 thinner, so that the present application can be better applied to thin door panels. The length of the shift block 121 determines the range of usable door leaf thickness, and the greater the length of the shift block 121, the greater the usable range. In order to avoid interference between the shift block 121 and the door leaf, an avoidance hole is provided on the door leaf for the shift block 121 to avoid, and the hole extends to the back side of the handle panel 100. When the two handle panels 100 are close to each other and the shift block 121 does not interfere with the door leaf and the handle panel 100 arranged on the other side of the door leaf during movement, the use requirements can be met.

[0037] When in actual use, the door handle lock has two handle panels 100, the guide groove 21 can also be set to one. When the heights of the two shift blocks 121 are consistent, the thickness of the guide groove 21 can be designed to ensure that the two shift blocks 121 do not interfere with each other during use. When the heights of the two shift blocks 121 are inconsistent, the width direction of the guide groove 21 along the vertical direction of the door leaf can accommodate the two shift blocks 121 without interfering with each other during use. The guide groove 21 and the number of shift blocks 121 set on the same handle 120 can also be adjusted according to different usage conditions.

[0038] The lock tongue 210 in the present application can also be used in conjunction with the linkage assembly in CN219431567U, the shift block 121 is replaced by the moving block in the linkage assembly, and the moving block is used to cooperate with the guide groove 21. When the handle 2 is pulled up, the linkage assembly is driven to make the moving block move or swing along the width direction of the door body, and the movement or swing of the moving block is used to drive the lock tongue 210 to retreat and unlock. After unlocking, the elastic part of the handle 2 is reset to reset the handle 2 to extend the lock tongue 210 outward; when the handle lock has a moving block shared by two handles, one guide groove 21 is set on the lock tongue 210, and when the handle lock has two moving blocks corresponding to the handles one by one, two guide grooves 21 are set on the lock tongue 210.

[0039] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the embodiments of the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
