Description

Technical Field

[0001] This utility model relates to the field of planar lock technology, specifically to a high-strength handle and a planar lock. Background Technology

[0002] Flat locks are a common type of door lock. Through an embedded structure design, the lock body becomes an integral part of the door surface, achieving better security and aesthetics. Flat locks have a wide range of applications. They can be used on doors in homes, offices, and shops as the primary lock to provide basic security and protection. They can also be used on drawers, cabinets, and other furniture, as well as on some windows, especially sliding or tilting windows, as window locks to provide additional security. Furthermore, flat locks are widely used as locking devices for indoor and outdoor equipment cabinets, such as industrial cabinet locks, equipment cabinets, power distribution cabinets, and communication cabinet locks. Through multi-point locking, they provide a simple, efficient, and economical enhanced protection measure, making the entire locking system safer and more reliable.

[0003] Traditional flat lock handles are mostly made of plastic or metal. Handles made of plastic have low strength and are easily damaged by external forces, thus failing to achieve the anti-theft effect. Furthermore, plastic is prone to aging and may break after prolonged use. While handles made entirely of metal have higher strength, they increase material and manufacturing costs, and the rust-proof layer on the outside of the handle is prone to rusting once it peels off. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-strength handle and a flat lock.

[0005] The purpose of this utility model can be achieved through the following technical solution: a high-strength handle, including a housing, a mounting part on the housing, a connecting part at one end of the housing, a reinforcing block embedded in the housing, a locking hole corresponding to the mounting part on the reinforcing block, and a bearing corresponding to the connecting part at one end of the reinforcing block.

[0006] Preferably, the shell is integrally formed with the reinforcing block by injection molding.

[0007] Preferably, the reinforcing block has positioning holes.

[0008] Preferably, the reinforcing block has multiple fixing holes.

[0009] Preferably, the reinforcing block has folded edges on both sides.

[0010] Preferably, the folded edge has a groove.

[0011] Preferably, the reinforcing block is either integral or multi-segmented.

[0012] This utility model also provides a planar lock, including a base and a handle that engages with the base. The handle is a high-strength handle as described above. A rotating shaft is rotatably provided on the base. One end of the rotating shaft is hinged to a connecting part. A bolt is provided at the other end of the rotating shaft. A lock cylinder is provided in the mounting part. A lock groove is provided on the base at the position corresponding to the lock cylinder.

[0013] Preferably, a torsion spring is provided on the rotating shaft, and one end of the torsion spring abuts against the handle.

[0014] The beneficial effects of this utility model are: by embedding a reinforcing block inside the shell, this utility model increases the strength and stability of the handle, preventing it from deforming or being damaged under force, and can better play the role of anti-sawing and anti-prying. The combination of two materials ensures the strength of the handle while reducing the cost of materials. Attached Figure Description

[0023] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0024] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1:

[0027] See Figures 1 to 4 As shown, the structure of this utility model is as follows: a high-strength handle, including a housing 1, the housing 1 is made of plastic, the housing 1 is provided with a mounting part 101, one end of the housing 1 is provided with a connecting part 102, the housing 1 is embedded with a reinforcing block 2, the reinforcing block 2 is integral and is integrally stamped from a single piece of metal material, the reinforcing block 2 is provided with a locking hole 201 corresponding to the mounting part 101, one end of the reinforcing block 2 is provided with a bearing seat 202 corresponding to the connecting part 102, the bearing seat 202 strengthens the strength and wear resistance of the connecting part 102.

[0028] Furthermore, the housing 1 is integrally formed with the reinforcing block 2 by injection molding. The reinforcing block 2 is pre-placed in the mold, and then molten plastic is injected to enclose the reinforcing block 2. After the plastic cools and solidifies, it forms the housing 1 and is tightly bonded to the reinforcing block 2 to form a whole, which greatly enhances the structural strength and durability of the handle. The metal reinforcing block 2 is enclosed in the housing 1, which also prevents the reinforcing block 2 from rusting.

[0029] like Figure 2 , Figure 3 As shown, the reinforcing block 2 has a positioning hole 203, which is used to ensure the accurate position of the reinforcing block 2 when the shell 1 is formed.

[0030] like Figure 3As shown, the reinforcing block 2 has multiple fixing holes 204. Specifically, molten plastic fills the fixing holes 204, and after cooling and hardening, it forms a whole, thereby firmly fixing the reinforcing block 2 in the shell 1.

[0031] like Figure 3 As shown, the reinforcing block 2 has folded edges 205 on both sides. The folded edges 205 can form an "L" shaped force-bearing structure, thereby strengthening the rigidity of the reinforcing block 2 and preventing the handle from bending under force.

[0032] Furthermore, the folded edge 205 is provided with a groove 206. A groove 206 is punched out on the bend to form a reinforcing rib, which is used to increase the strength of the folded edge 205.

[0033] Example 2:

[0034] In this embodiment, the reinforcing block 2 is multi-segmented, such as... Figure 4 As shown, reinforcing block 2 is made of two or more pieces of metal materials joined together.

[0035] like Figure 5 , Figure 6 As shown, this utility model also provides a planar lock, including a base 3 and a handle that engages with the base 3. The handle is a high-strength handle as described above. A rotating shaft 301 is rotatably mounted on the base 3. One end of the rotating shaft 301 is hinged to the connecting part 102, and the other end of the rotating shaft 301 is provided with a bolt 302. A lock cylinder 4 is provided inside the mounting part 101, and a lock groove 303 is provided on the base 3 at the position corresponding to the lock cylinder 4. In actual use, when locking, rotating the handle causes the bolt 302 to rotate and lock through the rotating shaft 301. Hold the cabinet door, then press the handle to engage with the base 3. At the same time, the bolt of the lock cylinder 4 engages with the lock groove 303, thus locking the cabinet door. To unlock, insert the key into the lock cylinder 4 and turn it, causing the bolt of the lock cylinder 4 to exit the lock groove 303. A torsion spring 304 is provided on the rotating shaft 301. One end of the torsion spring 304 abuts against the handle. The handle pops out under the action of the torsion spring 304. Then turn the handle, which drives the bolt 302 to rotate through the rotating shaft 301, so that the bolt 302 no longer engages with the cabinet door, thus opening the cabinet door.

[0036] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
