[0022] like Figures 1 to 3As shown, this embodiment provides a lock body with a concealed handle, including a housing 1, a bolt assembly 2, a latch 3, a handle 4, a brake pad 5, a button 6, and a backing plate 7. The backing plate 7 is installed on one side of the housing 1 and will be installed on the glass door frame. The housing 1 has a cavity inside and is composed of an upper cover plate and a lower cover plate. The backing plate 7 has a first through hole 71, a second through hole 72, and a third through hole 73. The button 6 is installed in the first through hole 71, and the handle 4... The latch assembly 2 is installed in the second through hole 72, and the latch assemblies 2 are installed in the third through hole 73. The latch 3 is disposed in the cavity and rotates. The rotation of the latch 3 drives the latch assembly 2 to extend and retract within the third through hole 73. The brake pad 5 is hinged and rotates within the cavity. The button 6 extends inward to form a push rod 61. The push rod 61 pushes the brake pad 5 to rotate. When the button 6 presses the push rod 61, the push rod 61 pushes the brake pad 5 to rotate clockwise by a very small angle. The handle 4 is equipped with... The device has a first transverse groove 41, and a first fixing post 11 is provided inside the housing 1. The first fixing post 11 is located in the first transverse groove 41 to limit the range of movement of the handle 4. A slot 42 is provided on the top of the handle 4. A locking block 51 is provided at the front end of the brake pad 5. A first spring 8 is provided on the brake pad 5. One end of the first spring 8 presses against the locking block 51, and the other end of the first spring 8 pushes the handle 4 forward. After the handle 4 is retracted, the locking block 51 is engaged in the slot 42. The handle 4 pushes the first spring 8, thus applying pressure to the locking block 51. The locking block 51 engages the slot 42, preventing the handle 4 from popping out of the housing 1. When the button 6 is pressed, the push rod 61 pushes the brake pad 5 to rotate clockwise, and the locking block 51 disengages from the slot 42. The handle 4 is then pushed out by the first spring 8. This structure allows the lock body to be installed in a slot on the door. The combination of the two improves the convenience of installation, reduces the overall space, and enhances stability.

[0023] As an optional embodiment, the position of the handle 4 near the locking block 51 is an arc-shaped structure. The arc-shaped structure makes it easier for the locking block 51 to engage with the locking slot 42 when the handle 4 is inserted.

[0024] As an optional embodiment, a protrusion 43 is provided on the right side of the handle 4 at the position where it contacts the end of the first spring 8. The first spring 8 pushes the protrusion 43 to extend the handle 4 outward. The protrusion 43 is used to be pushed by the first spring 8 to extend the handle 4. In addition, the protrusion 43 can make the handle 4 more stable and prevent it from shaking.

[0025] As an optional embodiment, the housing 1 is provided with a second fixing post 12, and the brake pad 5 and the first spring 8 are hinged to the second fixing post 12. This structure is simple and more compact overall.

[0026] As an optional embodiment, the latch assembly 2 includes a front latch 21, a latch hook 22, and a push plate 23. The front latch 21 is fixedly connected to the push plate 23. The front end of the push plate 23 is provided with notches 231 at the top and bottom. The latch hook 22 is located in the notches 231 and is symmetrically arranged. The latch hook 22 is hinged to the front latch 21. When the push plate 23 is pushed forward, the latch hook 22 rotates outward after hitting the liner 7. When the push plate 23 moves inward, the latch hook 22 rotates inward after hitting the stop plate 13. This structure is simpler and more convenient.

[0027] As an optional embodiment, the housing 1 is provided with a third fixing post 14 and a fourth fixing post 15, and the push plate 23 is fitted on the third fixing post 14 and the fourth fixing post 15 to limit the movement. The third fixing post 14 and the fourth fixing post 15 can make the locking tongue assembly 2 move horizontally.

[0028] As an optional embodiment, a second spring 31 is provided between the end of the latch 3 and the third fixing post 14. When the latch assembly 2 is outside or inside the housing 1, the second spring 31 will apply pressure to the latch 3 so that it will not loosen when rotating.

[0029] Currently, the handle and lock body are separate products, requiring two slots for installation, which is cumbersome and space-consuming. Therefore, a lock body with a concealed handle is provided, allowing the handle and lock body to be integrated as a single unit. The button 6 is installed in the first through hole 71, the handle 4 is installed in the second through hole 72, and the bolt assembly 2 is installed in the third through hole 73. The pawl 3 rotates to drive the bolt assembly 2 to extend and retract within the third through hole 73. The button 6 extends inward to form a push rod 61, which pushes the brake pad 5 to rotate. The brake pad 5 will be driven to rotate clockwise. The front end of the brake pad 5 is provided with a locking block 51. The brake pad 5 is provided with a first spring 8. One end of the first spring 8 presses the locking block 51, and the other end of the first spring 8 pushes the handle 4 forward. When the button 6 is pressed, the push rod 61 will push the brake pad 5 to rotate clockwise, and the locking block 51 will disengage from the slot 42. The handle 4 will be pushed out by the first spring 8. This structure allows the lock body to be installed in a slot that only needs to be made on the door. The two are combined, which improves the convenience of installation, reduces the overall space, and enhances stability.
