[0001] The present application relates to the technical field of door locks, and in particular to a handle lock with a concealed handle. Background Art
[0002] With the continuous development of the security industry, various locks have appeared in the handle lock industry, including electronic locks and anti-theft locks, etc. These locks can play a good security role. The handle lock usually includes three parts: a lock body and two handle panels. The handle on the traditional handle panel is fixed and protrudes from the outer side of the lock plate. Children at home can easily bump into the handle on the outer side of the lock plate when playing, which poses a safety hazard. Therefore, a handle lock with a hidden handle has appeared, such as CN 219431567U. In order to adapt to the structural change of the handle, the existing handle lock uses a handle drive linkage component to realize the drive of the lock tongue, which makes the structure of the handle panel complicated, thereby increasing the failure points of the lock body and reducing the durability of the lock body. When the handle lock using the handle panel is directly installed on a door body with a larger thickness, the output end of the handle panel may be separated from the lock tongue. In order to make the handle panel reliable for use with the lock core, it is necessary to increase the length of the drive block acting on the lock tongue by installing an extension piece before installation. Therefore, different lengths of extension pieces are required for door bodies of different thicknesses, which will cause certain inconveniences in use. Utility Model Content
[0003] In view of this, the present application provides a handle lock with a hidden handle to solve the technical problems of the handle panel of the existing handle lock with a hidden handle having a complex structure, reduced durability, and the inconvenience of using the existing handle lock on door leaves of different thicknesses.

A slot for the shift block to pass through and move is provided on the bottom surface of the mounting groove, and the shift block directly acts on the lock tongue of the lock body.
[0006] Furthermore, the lock tongue is provided with a guide groove for the shift block to be inserted into.
[0007] Furthermore, when the handle lock has two handle panels, the lock body is located between the two handle panels, and the lock tongue has two guide grooves offset in the vertical direction, and the two guide grooves cooperate with the corresponding shifting blocks of the handle panels respectively.
[0008] Furthermore, a limiting protrusion is provided on the inner side surface of the handle, and the limiting protrusion is used to abut against the panel body to limit the maximum pulling angle of the handle.
[0009] Furthermore, a detachable fixing seat is installed in the installation groove, and one end of the rotating shaft is connected to the fixing seat to achieve fixation.
[0010] Furthermore, the cross section of the fixing seat parallel to the outer side surface of the panel body is in the shape of an isosceles trapezoid, the inner wall of the installation groove has a limiting groove that cooperates with the fixing seat, and the outer end of the installation groove extends to the outer side surface of the panel body.
[0011] Furthermore, at least one limiting seat is provided on the bottom side of the installation groove, and the handle is pressed against the limiting seat when it is reset, and a shock absorbing block is provided on the end surface of the limiting seat that contacts the handle.

DETAILED DESCRIPTION
[0027] 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.
[0028] refer to Figures 1 to 10 ,like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig. 9 As shown, the present embodiment provides a handle lock with a hidden handle, comprising at least one handle panel 100 and a lock body 200. A lock hole and a handle 2 are provided on the panel body 1 of the handle panel 100. A mounting groove 11 is provided on the outer side surface of the panel body 1. The handle 2 is hingedly mounted in the mounting groove 11 using a rotating shaft 3 parallel to the panel body 1. The handle 2 is hidden in the mounting groove 11 when reset. An elastic reset member is provided between the handle 2 and the panel body 1. A shift block 22 is provided on the inner side surface of the handle 2 close to the panel body 1. A card slot 12 for the shift block 22 to pass through and move is provided on the bottom surface of the mounting groove 11. The shift block 22 directly acts on the lock tongue 210 of the lock body 200.
[0029] In the above technical solution, the handle 2 is hidden in the installation groove 11 when it is in a stable reset state under the action of the elastic reset member, preventing children from touching the handle and causing bumps while playing, reducing safety hazards, and improving the safety performance of the handle lock. When in use, the handle 2 is pulled out to make the push block 22 move in the slot 12 and drive the lock tongue 210 to shrink inward and retreat, thereby unlocking the door and allowing the door leaf to be opened. The setting of the slot 12 can allow the push block 22 to pass through the panel body 1, and at the same time, the panel body 1 can be used to cover the internal structure of the handle lock, making the structure beautiful.
[0030] Specifically, Fig.10 As shown, a plurality of fixing seats 21 for the rotation shaft 3 to pass through are provided on the inner side surface of the handle 2 close to the panel body 1, and the shift block 22 is connected to the corresponding fixing seat 21, and the elastic reset member is preferably a torsion spring sleeved on the rotation shaft 3, and the two ends of the torsion spring act on the panel body 1 and the handle 2 respectively, and the shift block 22 passes through the card slot 12 and directly acts on the lock tongue 210, such as the shift block 22 abuts against the side protrusion of the lock tongue 210 and works in combination with the spring acting on the tail of the lock tongue 210 to enable the lock tongue 210 to passively retreat and automatically reset, or the shift block 22 is inserted into the corresponding guide groove 211 on the lock tongue 210 to achieve linkage, wherein the guide groove 211 can be designed to be a non-through hole or a through hole as needed, and the lock tongue 210 is linked by the movement of the shift block 22, and the number of the shift blocks 22 located on the same handle 2 can be adjusted according to the width of the lock tongue 210.
[0031] Preferably, the lock tongue 210 is provided with a guide groove 211 into which the shift block 22 can be inserted. In the technical solution in which the shift block 22 is inserted into the guide groove 211, the swinging and floating of the shift block 22 can be used to limit the backward limit position of the lock tongue 210, so as to prevent the lock tongue 210 from excessively retreating and separating from the shift block 22 and affecting the use function of the handle lock. At the same time, the automatic reset of the handle 2 can be used to drive the lock tongue 210 to automatically extend and reset, thereby reducing the use of the reset spring and the front limit structure directly acting on the lock tongue 210, and making the internal structure of the lock body 200 simple.
[0032] When the handle lock has a handle panel 100 and the lock tongue 210 can be moved backward by using the handle 2 alone, the handle panel 100 is used as an inner handle panel to facilitate quick door opening from indoors.
[0033] When the handle lock has two handle panels 100 , the lock body 200 is located between the two handle panels 100 , and the shifting block 22 of the handle panel 100 is inserted into the corresponding guide groove 211 .
[0034] Specifically, when the depth of the guide groove 211 is appropriate, the two shift blocks 22 of the inner and outer handle panels 100 can share a guide groove 211, and the two shift blocks 22 can have the same height. When the depth of the guide groove 211 is shallow, the two shift blocks 22 can be staggered along the width direction of the guide groove 211 to produce a certain intersection to avoid mutual interference and affect use, wherein the width direction of the guide groove 211 is the direction consistent with the extension direction of the door height.
[0035] Preferably in the present application, the handle lock has two handle panels 100 , the lock body 200 is located between the two handle panels 100 , and the lock tongue 210 has two guide grooves 211 offset in the vertical direction, and the two guide grooves 211 cooperate with the corresponding shifting blocks 22 of the handle panels 100 .
[0036] Specifically, when two guide grooves 211 are provided, the crossbeam located between the two guide grooves 211 can be used to increase the strength of the lock tongue 210, so that the lock tongue 210 is not easily deformed, and the vertical direction in the present application is the direction consistent with the extension direction of the door height. 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 shift block 22 will not separate from the corresponding guide groove 211, which is suitable for use with door bodies of various thickness specifications. Since the linkage component is removed from the handle panel 100, the thickness of the handle panel 100 is thinner, so that the present application can also be better applied to thin door panels. The length of the shift block 22 determines the range of usable door leaf thickness, and the larger the length of the shift block 22, the larger the usable range. In order to avoid interference between the shift block 22 and the door leaf, an avoidance through hole for the shift block 22 to avoid is provided on the door leaf, and the through hole extends to the back of the handle panel 100. When the two handle panels 100 are close to each other and the shift block 22 does not interfere with the door leaf during movement, both can meet the use requirements.
[0037] In an embodiment of the present application, the lock body 200 also includes a lock box 220 for installing the lock tongue 210. A locking member 230 that slides in a vertical direction is provided in the lock box 220. The locking member 230 is used to prevent the lock tongue 210 from retracting and retreating to achieve reverse locking. When the lock core 300 is rotated by operating a knob or a key, the locking member 230 can be driven to move to unlock the lock tongue 210. At this time, the operating handle 2 enables the lock tongue 210 to move to achieve unlocking.
[0038] In the embodiments of the present application, Figure 8 As shown, a limiting protrusion 23 is further provided on the inner side surface of the handle 2 , and the limiting protrusion 23 is used to abut against the panel body 1 to limit the maximum pulling angle of the handle 2 .
[0039] Specifically, the limiting protrusion 23 has an axial hole for the rotating shaft 3 to pass through, and the bottom side of the mounting groove 11 is provided with a boss 13 that can abut against the raised portion of the limiting protrusion 23. The boss 13 is not easy to deform, so that the handle panel 100 can maintain its beauty for a long time. At the same time, the limiting protrusion 23 and the boss 13 abutting against each other can also prevent the lock tongue 210 from retreating excessively and separating from the shift block 22 to affect the use function.
[0040] In order to facilitate and stabilize the installation of the rotating shaft 3, a detachable fixing seat 4 is installed in the installation groove 11, and one end of the rotating shaft 3 is connected to the fixing seat 4 for fixing. Since the wall thickness of the panel body 1 is relatively thin, the installation stability of the rotating shaft 3 is poor. The setting of the fixing seat 4 increases the fixed length of the rotating shaft 3 and improves the installation stability of the rotating shaft 3.
[0041] In order to improve the installation stability of the fixing seat 4, the cross-section of the fixing seat 4 parallel to the outer side surface of the panel body 1 is in the shape of an isosceles trapezoid, and the inner wall of the installation groove 11 is provided with a limiting groove 14 that cooperates with the fixing seat 4. The fixing seat 4 is stably installed by utilizing the fitting cooperation between the installation groove 11 and the fixing seat 4, and the outer end of the installation groove 11 extends to the outer side surface of the panel body 1, so that the fixing seat 4 is easy to install, wherein the fixing seat 4 is preferably fixedly connected to the panel body 1 by screws.
[0042] In the embodiment of the present application, at least one limiting seat is provided at the bottom side of the mounting groove 11, and the handle 2 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 2. The limiting seat is used to form a channel for finger insertion between the handle 2 and the bottom side of the mounting groove 11, so that the handle 2 is easy to operate, and the support of the limiting seat can ensure that after the handle 2 is automatically reset, the outer side surface of the handle 2 and the outer side surface of the panel body 1 are in the same plane, so that the handle 2 is well hidden in the mounting groove 11, and the handle 2 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 2 and the limiting seat when the handle 2 is automatically reset, making it comfortable to use, and can prevent the limiting seat from being frequently subjected to large impact forces and causing damage.
[0043] The outer side of the panel body 1 is provided with a decorative plate which can be fixed by screws or adhesively connected. The panel body 1 is also provided with a cover plate fixed by a magnetic structure, and the cover plate is used to protect the lock core 300 which is connected to the lock hole on the panel body 1.
[0044] 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.
