Description

Technical Field

[0001] The utility model relates to the technical field of steel wire seals, in particular to a steel wire seal with an anti-pull mechanism. Background Art

[0002] Wire seals are auxiliary equipment used to seal containers, equipment instruments, and key instruments that require key monitoring. When logistics transport containers pass through customs, they can control risks and reduce losses, and have an important impact on risk prevention. They can be tightened using disposable wire seals on the opening and closing parts of containers, instruments and key equipment, which can facilitate management (goods can be counted by coding) and ensure the safety of goods during circulation.

[0003] The internal principle of the wire seal is very simple. One end of the lock belt is fixedly connected to the lock body inside the lock body, and the other end of the lock belt is connected to the lock head. The lock body is provided with a countersunk hole through which the lock head can pass. There is an inclined hole on the lock body that communicates with the countersunk hole. A spring is installed in the inclined hole. A steel ball is installed at the intersection of the inclined hole and the countersunk hole. The steel ball is supported by the corresponding spring. When using the seal, after the lock belt passes through the sealing part of the package, the lock belt is inserted into the through hole of the lock body. Under the action of the corresponding springs, the steel balls are pressed into the grooves of the lock belt respectively to complete the seal.

[0004] When the wire seal is used, the locking belt is formed into a loop to press the object tightly, and then the seal is inserted into the countersunk hole and the seal is tightened so that the loop cannot be enlarged to fix the object. However, when in use, the locking belt can still be pulled, and the locking belt continues to press the object tightly. If it is too tight, it is easy to cause damage to the object. In order to prevent the locking belt from being pulled after the wire seal fixes the object, causing excessive clamping force on the object, a wire seal with an anti-pull mechanism is provided. Utility Model Content

[0005] The utility model aims to provide a wire seal with an anti-pulling mechanism in order to prevent excessive clamping force on the object caused by pulling the lock belt after the wire seal is fixed to the object.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wire seal with an anti-pull mechanism, comprising a lock body and a lock belt, one end of the lock belt is fixed inside the lock body, the other end of the lock belt is fixedly connected to a lock head, the outer wall of the lock body is provided with a countersunk hole penetrating the lock body, and the lock belt is fixed to the inner cavity of the countersunk hole through the anti-pull mechanism;

[0008] The clamping unit includes a movable groove, which is opened inside the lock body and located on one side of the countersunk hole. One end of the movable groove is connected to the countersunk hole. A clamping block is slidably connected to the inner wall of the movable groove. A threaded hole is opened on the outer wall of one side of the lock body. The threaded hole is connected to the movable groove, and a bolt is connected to the inner wall of the threaded hole.

[0009] As a further solution of the utility model: the bending unit includes a groove, the groove is opened on the outer wall of the lock body and is located at one end of the countersunk hole, the outer wall of the clamping block is fixedly connected with an insert plate, the insert plate extends into the inner cavity of the groove, the outer wall of the insert plate is opened with a through hole, the through hole is for the lock belt to pass through, and the inner wall of the groove is opened with a slot on one side, the slot is for the insert plate to be inserted.

[0010] As a further solution of the utility model: an inclined hole is opened inside the lock body on the side of the countersunk hole away from the movable groove, the inclined hole is connected to the countersunk hole in an inclined state, a steel ball is arranged at the junction of the top end of the inclined hole and the countersunk hole, and a spring for supporting the steel ball is installed in the inner cavity of the inclined hole.

[0011] As a further solution of the utility model: the inner wall of the movable groove is in contact with the outer wall of the clamping block, and the shape of the clamping block is L-shaped.

[0012] As a further solution of the utility model: the threaded hole matches the bolt.

[0014] As a further solution of the utility model: the inner wall of the slot fits with the outer wall of the plug board, and the plug board is square in shape.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] By setting an anti-pulling mechanism, the bolt is installed into the threaded hole, and the bolt is turned to contact the clamping block, which pushes the clamping block to slide. One end of the clamping block moves into the inner cavity of the countersunk hole and contacts the locking belt, pressing the locking belt into the countersunk hole. When the clamping block moves, the movement of the clamping block drives the plug plate to move, and the movement of the plug plate pulls the locking belt through the through hole to move, so that the locking belt is bent. When the clamping block completes pressing the locking belt, the plug plate is inserted into the slot, and the locking belt has two bends, which makes it impossible for the locking belt to slide in the countersunk hole, making it easy to fix the locking belt in the countersunk hole and prevent the locking belt from being pulled and moved.
