Description

Technical Field

[0001] This utility model relates to a lock, specifically an adjustable locking device. Background Technology

[0002] A wire rope securing device is used to secure steel wire ropes, commonly found in the construction industry and other sectors requiring tensile testing and fixation. The main function of a wire rope securing device is to secure the steel wire rope via sliding jaws and adjust its tension to ensure proper tension is applied to the rope.

[0003] When using existing wire lock devices, the wire rope is fixedly connected to the lock head, and the positional relationship between the wire rope and the lock head is not adjustable. Therefore, the length of the wire rope cannot be adjusted according to actual usage needs, which makes it inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable wire lock, in which the relative position between the wire rope and the lock head can be adjusted at will, thereby adapting to various practical needs and making it more convenient to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable wire lock, comprising a lock body and a steel wire rope disposed on the lock body. The lock body includes a lock head, a first locking mechanism and a hand-tightening nut disposed on the lock head. Both ends of the steel wire rope pass through the lock head. A receiving groove is provided inside the lock head, and a shrinking inner groove is provided on one side of the receiving groove. The first locking mechanism includes a protruding head and an extension head disposed on one side of the protruding head. The extension head is located inside the shrinking inner groove. The hand-tightening nut is disposed on the protruding head. The lock body also includes a second locking mechanism, which is disposed at the end of the lock head away from the first locking mechanism. The second locking mechanism includes an outer protrusion and an engaging head disposed on one side of the outer protrusion. The engaging head is disposed inside the receiving groove.

[0006] Preferably, there are two receiving slots and two shrinking inner slots, and the two receiving slots are distributed on both sides of the lock head.

[0007] Preferably, there are two first locking mechanisms and two hand-tightening nuts, with the two first locking mechanisms distributed on both sides of the lock head.

[0008] Preferably, an oblique outer wall is formed on the outer side of the expansion head, and the oblique outer wall is adapted to the inner wall of the shrinking inner groove; so that when the expansion head is compressed, the oblique outer wall will be in close contact with the shrinking inner groove, thereby compressing the expansion head by the locking head and tightening the wire rope, so that the wire rope and the locking head are fixed together.

[0009] Preferably, the hand-tightening nut abuts against the lock head; the hand-tightening nut can be rotated on the protruding head, thereby adjusting the relative position of the protruding head and the lock head.

[0010] Preferably, the wire rope passes through the inside of the protruding head, the extension head, and the outer protrusion; this allows the protruding head, the extension head, and the outer protrusion to lock the wire rope, ensuring the stability of the lock body and the wire rope after they are fixed.

[0011] Preferably, a locking nut is installed on the outer protrusion and inserted therein, and the locking nut is pressed onto the wire rope; thereby, the locking nut further restricts the wire rope.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model limits both ends of the wire rope by setting a first locking mechanism and a second locking mechanism at both ends of the lock head. The wire rope is limited by two sets of locking mechanisms, which makes the limiting effect of the wire rope better. Moreover, the relative position between the wire rope and the lock head can be adjusted at will, thereby adapting to various different actual use needs, making it more convenient to use, and making the application range of the wire lock wider.

[0021] Please see Figures 1 to 4This utility model provides an embodiment of an adjustable wire lock, comprising a lock body 1 and a steel wire rope 2 disposed on the lock body 1. The lock body 1 includes a lock head 11 and a first locking mechanism 12 and a hand-tightening nut 13 disposed on the lock head 11. Both ends of the steel wire rope 2 pass through the lock head 11. A receiving groove 111 is provided inside the lock head 11, and a shrinking inner groove 112 is provided on one side of the receiving groove 111. There are two receiving grooves 111 and two shrinking inner grooves 112, and the two receiving grooves 111 are distributed on both sides of the lock head 11. The locking mechanism 12 includes a protruding head 121 and an extension head 122 disposed on one side of the protruding head 121. The extension head 122 is located inside the contraction inner groove 112. An inclined outer wall 123 is formed on the outer side of the extension head 122. The inclined outer wall 123 is adapted to the inner wall of the contraction inner groove 112, so that when the extension head 122 is compressed, the inclined outer wall 123 will come into close contact with the contraction inner groove 112, thereby compressing the extension head 122 under the control of the locking head 11 and tightening the wire rope 2, so that the wire rope 2 and the locking head 11 are fixed together. The nut is then tightened by hand. A first locking mechanism 13 is disposed on the protruding head 121, and the hand-tightening nut 13 abuts against the lock head 11. The hand-tightening nut 13 can rotate on the protruding head 121, thereby adjusting the relative position of the protruding head 121 and the lock head 11. Two first locking mechanisms 12 and two hand-tightening nuts 13 are provided. The two first locking mechanisms 12 are distributed on both sides of the lock head 11. The lock body 1 also includes a second locking mechanism 14. The second locking mechanism 14 is disposed at the end of the lock head 11 away from the first locking mechanism 12, and the second locking mechanism 14 includes an outer protrusion 141 and a... The engagement head 142 on one side of the outer protrusion 141 is located inside the receiving groove 111. The wire rope 2 passes through the protrusion 121, the extension head 122 and the outer protrusion 141, so that the protrusion 121, the extension head 122 and the outer protrusion 141 can lock the wire rope 2, ensuring the stability of the lock body 1 and the wire rope 2 after they are fixed. A locking nut 15 is installed on the outer protrusion 141 and inserted into it. The locking nut 15 is pressed onto the wire rope 2, so that the locking nut 15 further restricts the wire rope 2.

[0022] When using this invention, if it is necessary to adjust the relative position of the locking head 11 and the wire rope 2, the two hand-tightening nuts 13 can be turned to gradually move away from the corresponding extension head 122, causing the oblique outer wall 123 to separate from the inner wall of the shrinking inner groove 112. Then, the two locking nuts 15 can be turned with the specified screwdriver tool to separate the two locking nuts 15 from the wire rope 2. In this way, the protruding head 121 and the extension head 122 can be separated from the wire rope 2 at the same time, so that the wire rope 2 can be separated from the protruding head 121 and the extension head 122. The inner movement of the outer protrusion 141 changes the relative position. After adjusting to the appropriate position, the two hand-tightening nuts 13 are turned again, causing the two hand-tightening nuts 13 to move slowly on the two protrusions 121, so that the inclined outer wall 123 fits tightly against the inner wall of the shrinking inner groove 112, compressing the expansion head 122 and pressing the wire rope 2. Then, the two locking nuts 15 are turned again, so that the two locking nuts 15 press against the surface of the wire rope 2, thus fixing the wire rope 2 again and completing the adjustment of the relative position of the lock head 11 and the wire rope 2.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
