Detailed implementation manners
[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0028] The structure of the existing U-shaped lock is fixed and cannot be adjusted according to the object to be locked, so its applicability is poor. At the same time, it occupies relatively more space.
[0029] To solve the above technical problems, this embodiment provides a bionic flexible lock. Please refer to Figures 1 to 5 as shown in Figure 1 It is a three-dimensional view of the bionic flexible lock in the embodiment, Figure 2 It is an exploded view of the bionic flexible lock in the embodiment, Figure 3 It is Figure 2 a schematic diagram of cross-section A in Figure 4 It is a three-dimensional view of the lock link in the embodiment, Figure 5 It is a schematic diagram of the connection between two adjacent lock links in the embodiment.
[0030] A bionic flexible lock of this embodiment, as Figure 1 shown, includes: a lock body 1, a lock head 2 and a lock catch 3. The lock head 2 and the lock catch 3 can be relatively locked and opened; the lock body 1 includes: a connecting rope 11 and at least two lock links 12. The two ends of the connecting rope 11 are respectively connected to the lock head 2 and the lock catch 3, so that the lock body 1, the lock head 2 and the lock catch 3 are connected into an integrated structure; as Figure 4 and Figure 5As shown, the locking joint 12 is provided with a through hole 101 for the connecting rope 11 to pass through, and a ball head 102, a ball neck 103 and a ball column 104 are sequentially provided along the axial direction of the through hole 101, the ball column 104 is provided with a ball hole 105 connected to the through hole 101, and the opening 106 of the ball hole 105 is located in the axial direction of the through hole 101, and the outer dimension of the ball neck 103 is smaller than the outer dimension of the ball head 102 and the ball column 104, and smaller than the size of the opening 106, and each locking joint 12 is sequentially sleeved on the connecting rope 11 through the through hole 101. In any two adjacent locking joints 12, the ball head 102 and the ball neck 103 of one locking joint 12 are respectively rotatably arranged in the ball hole 105 and the opening 106 of the other locking joint 12, and the outer dimension of the ball head 102 is larger than the size of the opening 106, so as to be limited in the ball hole 105, so that each locking joint 12 forms a chain structure. Among them, since the ball neck 103 is limited by the opening 106, the ball head 102 can rotate around the ball hole 105 within a certain range, so that two adjacent lock joints 12 are inclined to each other. At the same time, the connecting rope 11 is also flexible, thereby realizing the mobility of the lock body 1 structure, which is different from the existing U-shaped lock fixed structure.
[0031] Understandably, see Figure 5 As shown, the outer dimension L2 of the ball neck 103 is smaller than the size L4 of the opening 106, so that it can rotate at the opening 106. At the same time, the outer dimension L2 of the ball neck 103 is smaller than the outer dimension L3 of the ball head 102 and the outer dimension L1 of the ball column 104, so that the ball neck 103 of one locking joint 12 is limited at the opening 106 of another locking joint 12 in two axial directions through the ball head 102 and the ball column 104 respectively; the outer dimension L3 of the ball head 102 is larger than the size L4 of the opening 106, so that no matter how it rotates in the ball hole 105, it cannot be separated from the ball hole 105 at any angle from the opening 106, thereby realizing the connection and limiting effect between the locking joints 12.
[0032] The bionic flexible lock of the above technical solution adopts the bionic principle and imitates the skeletal structure characteristics of snakes, so that the lock body 1 is mainly composed of a connecting rope 11 and a lock joint 12, wherein the lock joints 12 are formed by the cooperation of the ball head 102 and the ball hole 105 to form a ball hinge structure, which can rotate relatively, so that the bionic flexible lock can bend as needed, such as when the lock head 2 and the lock buckle 3 are opened, it can be bent according to the shape of the locked object, or bend into an S shape when stored, or bend into a concave shape when the lock head 2 and the lock buckle 3 are locked, thereby reducing the occupied space. Compared with the traditional U-shaped lock, it has the advantages of flexible structure and reduced occupied space.
[0033] The assembly between the above-mentioned locking joints 12 can be achieved by existing methods. Exemplarily, the assembly between the ball head 102 and the ball hole 105 of the above-mentioned locking joint 12 is achieved through a thermal expansion process. The thermal expansion process utilizes the characteristics of different expansion coefficients (i.e., thermal expansion coefficients) of different metal materials. When a metal material is heated, its molecules begin to vibrate, generating heat due to friction and collision, causing the metal atoms to expand, thereby changing the size (length, width, height) of the metal material. This change causes the opening 106 of the ball column 104 to increase due to expansion. Correspondingly, the ball head 102 can reduce its size by cooling, and then smoothly enter the ball hole 105 through the opening 106.
[0034] The quantity and size of the above-mentioned locking joints 12 can be set according to the degree of variability required by the lock body 1. Exemplarily, when the lock body 1 has a higher requirement for the degree of variability, the number of locking joints 12 can be appropriately increased, and the size can be appropriately reduced.
[0035] It can be understood that the above-mentioned ball column 104 is used to form the ball hole 105 and connect the ball neck 103. Without limiting its external structure itself, under the condition of meeting the movement and connection functions of the lock body 1, exemplarily, the ball column 104 can be a cylinder, a polygonal column, an irregular column, a block, or an irregular shape.
[0036] In one implementation manner of connecting the above-mentioned connecting rope 11 with the lock head 2 and the lock buckle 3, both ends of the connecting rope 11 are respectively connected to the lock head 2 and the lock buckle 3 by means of screwing or tying.
[0037] While providing basic protection functions, the U-shaped wheel locks on the current market have significant safety hazards. First, their open design exposes the lock body to the external environment, making it vulnerable to adverse factors such as moisture and salt during long-term use, resulting in frequent rust problems, which not only affect the appearance but may also weaken the mechanical strength of the lock. At the same time, the open design of traditional U-shaped wheels provides an opportunity for malicious destroyers and is difficult to resist high-intensity destruction means, such as the powerful shearing of a large hydraulic clamp or the high-speed cutting of a grinder. These tools can easily damage the lock body structure in a short time, thus greatly reducing the safety protection level of the vehicle and the items carried. To solve this technical problem, in some implementation manners, refer to Figure 1 、 Figure 2 and Figure 3As shown, the lock body 1 further includes an anti-saw layer 13, an anti-shear layer 14, a fireproof layer 15, a waterproof layer 16 and an appearance layer 17, which are arranged concentrically from the inside to the outside with the lock joint 12 as the center. Among them, the anti-saw layer 13, the anti-shear layer 14, the fireproof layer 15, the waterproof layer 16 and the appearance layer 17 are made of flexible materials, and the specific materials can be selected according to the functions to be realized. For example, the anti-saw layer 13 is made of ultra-high molecular weight polyethylene (UHMWPE) material to improve the anti-saw performance, the anti-shear layer 14 is made of Kevlar material to improve the puncture resistance and shear resistance, the fireproof layer 15 is nylon 66, or a flame retardant is added to nylon 66 to improve the high temperature resistance, the waterproof layer 16 is made of nylon 6 soaked in waterproof coating to improve the waterproof performance, and the appearance layer 17 is made of nylon 612 and plays a decorative role. The anti-saw layer 13, anti-shear layer 14, fireproof layer 15, waterproof layer 16 and appearance layer 17 can be formed by weaving corresponding materials. In this way, five layers of functional fabrics are added outside the chain structure, which have the effects of waterproofing, fireproofing, shearing resistance and anti-sawing, greatly improving the safety and anti-destruction property of the bionic flexible lock.
[0038] It is understandable that the anti-saw layer 13, anti-shear layer 14, fireproof layer 15, waterproof layer 16 and appearance layer 17 can also be used separately or in combination according to the needs of use. Exemplarily, the lock body 1 includes an anti-saw layer 13, which is made of a flexible material and is coated on the periphery of the lock joint 12; Exemplarily, the lock body 1 includes an anti-shear layer 14, which is made of a flexible material and is coated on the periphery of the lock joint 12; Exemplarily, the lock body 1 also includes a fireproof layer 15, which is made of a flexible material and is coated on the periphery of the lock joint 12; Exemplarily, the lock body 1 also includes a waterproof layer 16, which is made of a flexible material and is coated on the periphery of the lock joint 12; Exemplarily, the lock body 1 also includes an appearance layer 17, which is made of a flexible material and is located on the outer surface of the lock body 1.
[0039] Exemplarily, the connecting rope 11 is a rope capable of improving tensile strength, such as a carbon fiber rope.
[0040] It is understandable that the structure for realizing relative locking and opening between the lock head 2 and the lock buckle 3 can be the same as that of the existing locks. Since it is not a technical problem to be solved by the present utility model, it will not be described in detail here.
[0041] Exemplarily, the sizes of the through hole 101 and the opening 106 are smaller than the end sizes of the lock head 2 and the lock buckle 3 , so that the lock sections 12 at both ends can be limited by the lock head 2 and the lock buckle 3 , so that the chain structure is limited between the lock head 2 and the lock buckle 3 .
[0042] Although embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model, and the scope of the present utility model is defined by the appended claims and their equivalents.
