Abstract
Description
Technical Field
[0001] This invention relates to the field of electronic lock technology, and in particular to an electronic lock cylinder structure that is resistant to drilling and prying. Background Technology
[0002] Electronic locks are widely used in people's daily lives as a common type of lock. With the development of society, the requirements for door locks in terms of security and convenience are also increasing. As a common type of lock, electronic locks usually consist of two main parts: electronic drive and mechanical transmission. The electronic drive part drives the mechanical transmission part to realize the unlocking and locking functions.
[0003] However, current electronic lock cylinders have low drill resistance. When using a power drill to pry open an electronic lock cylinder, ordinary electronic lock cylinders are easily damaged by the force of the drill, and the prying time is short, making it easy for thieves to open the door by force. Therefore, it is necessary to design an electronic lock cylinder with strong drill resistance to address the above-mentioned shortcomings and improve security. Summary of the Invention
[0004] The purpose of this invention is to provide a drill-proof and pry-proof electronic lock cylinder structure to solve the problems existing in the prior art, thereby improving the drill-proof and pry-proof capabilities of the electronic lock cylinder and enhancing its security.
[0005] To achieve the above objectives, the present invention provides the following solution:
[0006] This invention provides an anti-drilling and anti-pry electronic lock cylinder structure, including a lock shell and a transmission assembly. The lock shell has a cavity, and the transmission assembly is disposed within the cavity. The transmission assembly includes a contact block for cooperating with a key to switch the open and closed states of the electronic lock cylinder. The lock shell has at least two anti-drilling pins and a keyhole corresponding to the contact block at the center of its end face. The lock shell has an anti-drilling groove on its outer periphery near the anti-drilling pins, and an anti-drilling block is disposed in the anti-drilling groove. An anti-drilling ball is embedded in the outer periphery of the lock shell with its open end facing the opening end. The anti-drilling pins, the anti-drilling block, the anti-drilling ball, and the contact block are all made of alloy material and are dispersedly arranged on the projection of the lock shell end face.
[0007] Preferably, the anti-drilling slot is a U-shaped anti-drilling slot, and the anti-drilling block is a U-shaped anti-drilling block that cooperates with the U-shaped anti-drilling slot.
[0008] Preferably, the lock housing has two anti-drilling pins at the center of its end face, and the two anti-drilling pins are arranged symmetrically about the axis of the lock housing.
[0009] Preferably, the contact block is disposed inside the lock housing with the open end of the U-shaped anti-drill block facing it.
[0010] The present invention achieves the following technical effects compared to the prior art:
[0011] This invention provides an anti-drilling and anti-pry electronic lock cylinder structure. At least two anti-drilling pins and a keyhole corresponding to a contact block are provided in the middle of the end face of the lock shell.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] The purpose of this invention is to provide a drill-proof and pry-proof electronic lock cylinder structure to solve the problems existing in the prior art, improve the drill resistance of the electronic lock cylinder, and enhance the security of use.
[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] like Figures 1-4 As shown, this embodiment provides an anti-drilling and anti-pry electronic lock cylinder structure, including a lock shell 1 and a transmission assembly. The lock shell 1 has a cavity, and the transmission assembly is disposed in the cavity. The transmission assembly includes a contact block 2, which is used to switch the open and closed states of the electronic lock cylinder in cooperation with a key. At least two anti-drilling pins 3 and a keyhole 4 corresponding to the contact block 2 are provided in the middle of the end face of the lock shell 1. An anti-drilling groove 5 is provided on the outer periphery of the end of the lock shell 1 near the anti-drilling pins 3. An anti-drilling block 6 is provided in the anti-drilling groove 5. An anti-drilling ball 7 is embedded in the outer periphery of the lock shell 1 with the open end of the anti-drilling block 6 facing it. The anti-drilling pins 3, anti-drilling blocks 6, anti-drilling balls 7 and contact blocks 2 are all made of alloy materials and are dispersedly arranged on the projection of the lock shell 1 end face.
[0023] Users can switch the electronic lock cylinder from the locked state to the unlocked state by inserting a key into keyhole 4, and switch the electronic lock from the closed state to the open state by rotating the key after inserting the key. When the electronic lock cylinder is in the locked state, the electronic lock is in the closed state. When the electronic lock cylinder is in the unlocked state, the electronic lock can be opened by rotating the key to make the electronic lock in the open state.
[0024] In this embodiment, the anti-drilling pin 3, anti-drilling block 6, anti-drilling ball 7, and contact block 2 are all made of high-hardness alloy material, and the anti-drilling pin 3, anti-drilling block 6, anti-drilling ball 7, and contact block 2 are distributed in a dispersed manner on the projection of the anti-drilling pin 3, anti-drilling block 6, anti-drilling ball 7, and contact block 2 on the end face of the lock shell 1. During the drilling process, each alloy component can generate a greater obstruction effect on the drill bit, thereby improving the anti-drilling and anti-pry capabilities of the electronic lock core and enhancing the security of the electronic lock core.
[0025] In this embodiment, the anti-drilling slot 5 is a U-shaped anti-drilling slot, and the anti-drilling block 6 is a U-shaped anti-drilling block that cooperates with the U-shaped anti-drilling slot. While improving the anti-drilling and anti-pry performance, it is also easy to disassemble and assemble.
[0026] In this embodiment, two anti-drilling pins 3 are provided in the middle of the end face of the lock housing 1, and the two anti-drilling pins 3 are arranged in a centrally symmetrical manner about the axis of the lock housing 1.
[0027] In this embodiment, the contact block 2 is disposed inside the lock housing 1, with the opening end of the U-shaped anti-drill block facing it.
[0028] The following are the test methods and inspection standards for the anti-drilling and anti-pry performance of electronic lock cylinders:
[0029] Test method: Install the electronic lock cylinder in the fixture and install the manual drill on the slider, so that the drill bit of the drill is aligned with the end face of the electronic lock cylinder. The speed of the drill is 500rpm to 800rpm and the power is 700W + / -10%.
[0030] Without impact, apply a force of no more than 300N±5% to the axial direction of the drilling rig and drill into multiple points on the surface of the lock core. The drilling time shall be no less than 10 minutes.
[0031] The testing organization should select the actual diameter of the lock cylinder surface and the application point (the actual exposed portion) for drill resistance testing. Each lock cylinder can be tested using a maximum of three drill bits. The drill bits used should be high-speed steel drills with a maximum diameter not exceeding 12mm.
[0032] Inspection standard: During the total time allowed in each test (including the time required to attempt to rotate the lock cylinder and the appropriate maximum net drilling time), when a maximum torque of 5 N·m is applied using a suitable tool, the locking drive element of the lock cylinder must not rotate to the open position.
[0033] The electronic lock cylinder structure provided by this invention was tested according to the above test method. After 10 minutes of testing, a maximum torque of 5 N·m was applied to the lock cylinder using a suitable tool. The locking drive element of the lock cylinder could not be rotated to the open position. The test shows that the electronic lock cylinder structure provided by this invention meets the requirements for anti-drilling and anti-pry performance, has excellent anti-drilling and anti-pry capabilities, and is safer to use.
[0034] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
