Description

Technical Field

[0001] This utility model relates to the field of door lock technology, and more specifically, to a handle seat structure. Background Technology

[0002] The prior art CN222457067U discloses a handle assembly, including a lock seat and a handle that rotates relative to the lock seat. A locking mechanism is provided in the mounting cavity. The locking mechanism includes a square bushing, a locking cam rotatably connected to the square bushing, and a locking ball. The locking ball is placed in a limiting groove formed between the locking cam and the square bushing. A lock cylinder is linked to one end of the locking cam. A lock shell is provided on the lock seat. A mounting frame is provided in the mounting cavity. The lock cylinder, locking cam, and square bushing are integrated on the mounting frame. The mounting frame is sleeved outside the lock shell and is fixedly connected to the handle. Rotating the handle causes the mounting frame to rotate relative to the lock shell. The lock shell or mounting frame is provided with a locking groove for limiting the ball. Rotating the locking cam causes the locking ball to extend and retract relative to the limiting groove, thereby driving a part of the locking ball to enter or leave the locking groove. This utility model integrates all parts into the mounting frame to form a modular component, which improves the subsequent assembly efficiency and the stability of the connected components is relatively good.

[0003] The square shaft sleeve of the aforementioned handle assembly is separately installed in the mounting cavity, which results in low overall strength of the handle when locked and requires improvement in its resistance to damage. Summary of the Invention

[0004] This utility model overcomes the shortcomings of the prior art. Its structure is reasonably designed. By integrally molding the convex sleeve part into the handle seat, the overall anti-damage strength is higher and it is easier to install the opposite rod.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A handle seat structure includes a handle seat, with a front mounting cavity and a rear mounting cavity connected to each other. The handle seat has an integrally formed protrusion in the front mounting cavity and an integrally formed groove with a recessed slot in the rear mounting cavity. The protrusion has a square rod hole and a connecting hole connecting the front mounting cavity and the rear mounting cavity in the square rod hole.

[0007] Preferably, the bottom of the groove is the mounting surface, the mounting surface is disposed on the convex sleeve, the connecting hole is disposed on the mounting surface, and the two sides of the convex sleeve are provided with through holes communicating with the groove.

[0008] Preferably, the opening position of one of the through holes is higher than the opening position of the other through hole.

[0009] Preferably, the recessed portion is provided with an extension groove that extends to the through hole.

[0010] Preferably, a contact block is provided inside the handle seat in the front mounting cavity.

[0011] The beneficial effects of this utility model are:

[0012] This utility model has a reasonable structural design. By integrally molding the protruding sleeve part into the handle seat, the overall anti-vandal strength is higher, and it is easier to install the opposite rod. Attached Figure Description

[0014] Figure 2 This is a structural diagram of a specific embodiment of the present utility model. Figure 2 .

[0015] In the diagram: 1. Handle seat; 11. Front mounting cavity; 12. Rear mounting cavity; 13. Contact block; 2. Protruding sleeve; 21. Square rod hole; 22. Connecting hole; 3. Groove; 31. Recessed groove; 32. Extension groove; 4. Mounting surface; 5. Through hole. Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-2 As shown, a handle seat structure includes a handle seat 1, with a front mounting cavity 11 and a rear mounting cavity 12 connected within the handle seat 1. A protruding sleeve portion 2 is integrally formed in the front mounting cavity 11, and a recessed portion 3 with a recessed groove 31 is integrally formed in the rear mounting cavity 12. A square rod hole 21 is provided on the protruding sleeve portion 2, and a connecting hole 22 connecting the front mounting cavity 11 and the rear mounting cavity 12 is provided in the square rod hole 21. The bottom of the recessed portion 3 is a mounting surface 4, which is disposed on the protruding sleeve portion 2. The connecting hole 22 is disposed on the mounting surface 4. Two sides of the protruding sleeve portion 2 are provided with through holes 5 communicating with the recessed groove 31. The opening position of one through hole 5 is higher than the opening position of the other through hole 5. An extension groove 32 extending to the through hole 5 is provided on the recessed portion 3. A contact block 13 is provided within the front mounting cavity 11 of the handle seat 1.

[0018] By adopting the above technical solution, in this utility model, by integrally molding the protruding sleeve 2 onto the handle seat 1, the overall anti-damage strength is higher, and the integral molding of the protruding sleeve 2 onto the handle seat 1 makes it easier to install the opposite rod.

[0019] The recessed portion 3 is designed for mounting the locking component of the handle, the connecting hole 22 allows the handle linkage rod to pass through, and the through hole 5 allows the locking component to pass through, thereby locking the connecting component on the convex sleeve 2 to the convex sleeve 2 for better locking effect. Furthermore, the extension groove 32 extends to the through hole 5, facilitating the assembly and replacement of the corresponding locking component.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
