They are widely used in thermally broken aluminum casement windows, sliding doors, and other applications.
[0003] Most square shaft lever handle locks currently on the market are made of stainless steel. Due to the single material and insufficient wear resistance, long-term use will cause scratches on the surface, affecting the appearance. In addition, the handle of the square shaft lever handle lock does not have anti-slip texture, which makes it easy for the hand to slip. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a wear-resistant square shaft handle lock, which has advantages such as wear resistance and solves the problems mentioned in the background technology.
[0005] To achieve the above-mentioned anti-wear and wear-resistant purpose, this utility model provides the following technical solution: a wear-resistant square shaft handle lock, including a lock body and a square shaft handle seat, wherein a lock pin seat and a mounting plate are provided inside the lock body, and a door lock button is provided on the upper part of the square shaft handle seat; The square shaft handle has multiple anti-slip textures on its handle. The square shaft handle is made of aluminum alloy, with a zinc alloy layer on the outer layer of the aluminum alloy. A protective film, which is a polyethylene film, is then applied to the outer layer of the zinc alloy layer.
[0006] As a further improvement of this utility model: a protective sleeve is provided on the outside of the square shaft handle. The protective sleeve is made of silicone material and is placed on the outside of the anti-slip texture to improve the grip.
[0007] As a further improvement of this utility model: a protective cover is provided on the outside of the lock body, the protective cover being made of stainless steel, which can protect the surface of the lock body.
[0008] As a further improvement of this utility model: threaded holes are provided at all four corners of the lock body, and locking bolts are provided inside the bolt holes. The four locking bolts are screwed into the threaded holes, and the lock body is installed on the window for fixation.
[0009] As a further improvement of this utility model, both the mounting plate and the locking pin seat are made of copper plate, which increases the strength of the mounting plate and the locking pin seat and prevents breakage.
[0010] As a further improvement of this utility model: a sealing ring is provided at the connection between the square shaft handle seat and the protective cover. The sealing ring is made of rubber material and can prevent dust from entering the lock body through the gap, thus preventing internal contamination.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, aluminum alloy can improve the lightness and corrosion resistance of the square shaft handle seat, zinc alloy layer improves strength and casting performance, protective film is made of polyethylene film, which can protect the surface of the square shaft handle seat, avoid surface scratches and increase wear resistance, and protective cover is made of stainless steel, which can protect the surface of the lock body without affecting the appearance.
[0012] 2. In this utility model, the anti-slip texture increases the friction between the hand and the square shaft handle, preventing the hand from slipping. The protective cover is placed on the outside of the anti-slip texture. The silicone material can improve the grip and prevent dust from adhering to the surface of the anti-slip texture, thus avoiding surface contamination. Attached Figure Description

[0014] In the diagram: 1. Lock body; 2. Protective cover; 3. Locking bolt; 4. Protective sleeve; 5. Mounting plate; 6. Square shaft handle seat; 7. Door lock button; 8. Anti-slip texture; 9. Lock pin seat; 10. Protective film; 11. Zinc alloy layer; 12. Aluminum alloy; 13. Sealing ring. Detailed Implementation
[0015] 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.
[0016] It should be noted that lock body 1 is existing technology and is common knowledge to those skilled in the art, so it will not be described in detail here.
[0017] Please see Figures 1-3In this embodiment of the utility model, a wear-resistant square shaft handle lock includes a lock body 1 and a square shaft handle seat 6. The lock body 1 is provided with a lock pin seat 9 and a mounting plate 5 inside, and the square shaft handle seat 6 is provided with a door lock button 7 on the upper part. The square shaft handle 6 has multiple anti-slip textures 8 on the handle. The square shaft handle 6 is made of aluminum alloy 12. The outer layer of aluminum alloy 12 is provided with a zinc alloy layer 11. The outer layer of zinc alloy layer 11 is provided with a protective film 10. The protective film 10 is a polyethylene film.
[0018] The square shaft handle 6 has a protective sleeve 4 on its outside, made of silicone material. The protective sleeve 4 is fitted over the anti-slip texture 8 to improve the grip. The lock body 1 has a protective cover 2 on its outside, made of stainless steel material, which protects the surface of the lock body 1. Threaded holes are provided at the four corners of the lock body 1, and locking bolts 3 are installed inside the bolt holes. By screwing the four locking bolts 3 into the threaded holes, the lock body 1 is installed on the window for fixation. The mounting plate 5 and the lock pin seat 9 are both made of copper plate, which increases the strength of the mounting plate 5 and the lock pin seat 9 and prevents breakage. A sealing ring 13 is provided at the connection between the square shaft handle 6 and the protective cover 2. The sealing ring 13 is made of rubber material and prevents dust from entering the interior of the lock body 1 through the gap, thus preventing internal contamination.
