Problems solved by technology

[0003] However, in this processing method, the diameter and position of the drilled holes are different during the processing of the pinholes, which may easily cause the gap between the marbles after assembly to be unstable. characteristics; while the gap is too small, the locking sensitivity is poor, or even unable to lock, which directly affects the performance
Moreover, there are many burrs at the intersection of the two holes of the pinhole and the lock cylinder hole, which are difficult to remove, and the steel wire is easy to get stuck during use; Difficult to grasp, easy to cause rivets to pop out, which affects the reliability of the seal

Embodiment Construction

[0020] Such as Figures 1 to 6 As shown, a tensioned steel wire seal includes a lock head 10 made of zinc alloy or other anti-rust alloy material, the lock head 10 is fixedly connected with one end 21 of the steel wire 20, and the lock head 10 is also provided with a free end for the steel wire 20 22 inserted into the lock cylinder hole 11 and the pinhole 12 for accommodating the pinball 14 and the spring 13, the diameter of the pinhole 12 is equal to or slightly larger than the diameter of the pinball 14, the front part of the pinhole 12 and the middle part of the lock core hole 11 Obliquely intersecting, the size of the connected area after the intersecting is mainly smaller than the diameter of the marble 14 in the direction perpendicular to the length of the hole. Obviously, the marble 14 will partially protrude into the lock cylinder hole 11 under the support of the spring 13 , but the part protruding into the lock cylinder hole 11 is smaller than the half sphere of the p...

Abstract

The present invention provides a steel wire seal, comprising a lock head and a steel wire with one end connected on the lock head. The lock head is provided with a lock cylinder hole for inserting the steel wire and a marble hole for containing the marble and a spring; the hole diameter of the marble hole is matched with the diameter of the marble; the front part of the marble hole is obliquely penetrated through the middle part of the lock cylinder hole; the size of an area of which the marble hole and the lock cylinder hole penetrate is less than the diameter of the marble. The seal is characterized in that the lock cylinder hole and the marble hole are composed by enclosing a hole wall on the lock head and the surface of an internal core; the internal core is located at the tail end between two holes and is fixedly connected with the lock head; the part where the internal core located at the tail end of the marble hole and the spring form a stop structure; the processing method comprises the steps as follows: compression molding the lock head, the parison comprising a big hole cavity, then filling with the marble and the spring and inserting in the big hole cavity by the specific internal core, and then fixedly connecting the lock head and the steel wire, thereby avoiding the secondary drilling process of the marble hole; the seal has the advantages of accurate size of each hole, good performance and convenient process.

Description

technical field [0001] The invention belongs to a one-time locking device for containers and bags, in particular to a steel wire seal. Background technique [0002] The processing and assembling method of the existing tensioned steel wire seals include: first integral die-casting of the zinc alloy material constituting the lock head, and the formed lock head includes a connecting hole for fixing the steel wire and a lock core hole for accommodating the free end of the steel wire , the lock cylinder hole is located in the middle of the lock head, and the connecting hole is parallel to it and located on the side of the lock head; in order to put the lock cylinder into the lock head and limit the one-way movement of the steel wire, it is also necessary to set a marble on the lock head The hole and the pin hole are obliquely inserted into the middle of the lock cylinder hole, and then the pinball and the spring are sequentially loaded into the pin hole, and the tail end of the p...
