Description

Technical Field

[0001] The utility model relates to the technical field of lead seals, in particular to a tension-type lead seal. Background Art

[0002] Lead locks play an important role in the field of supervision, especially in places that require strict monitoring, such as instruments and containers. Once properly installed, these lead locks cannot be opened except by violent means. There are two main types of lead locks on the market: traditional and electronic. Regardless of which type, they contain two basic components: a lock seat and a lead seal wire. After the lead seal wire enters the lock seat, it is mainly clamped by the cooperation of springs and balls. However, at this time, the connection is only a high upper limit of the load-bearing force. If the force exceeds this upper limit, the lead seal wire will still detach from it, so it is necessary to reduce the occurrence of this problem.

[0003] Therefore, a tension-type sealing block is proposed to solve or alleviate the above problems. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] A tension-type lock, such as Figure 1-5As shown, it includes a lock base 1 and a sealing wire 2 fixedly connected to the lock base 1, the sealing wire 2 is a stainless steel bar, there is a accommodating cavity 103 in the lock base 1, and both ends of the lock base 1 are provided with through grooves connected to the accommodating cavity 103, the through grooves include a circular hole 101 and a cross groove 102 coaxially arranged therewith, the sealing wire 2 can pass through the two through grooves, and the sealing wire 2 is stamped along its length direction to form a plurality of limiting pieces 1 201 and limiting pieces 2 202, the limiting pieces 1 201 and the limiting pieces 202 are alternately arranged, and the connecting holes 203 are opened on the limiting pieces 1 201 and the limiting pieces 202, and the limiting pieces 1 201 and the limiting pieces 202 are spaced apart.

[0022] A one-way connection component is provided in the lock base 1 and is located in the accommodating chamber 103. A plurality of connection holes 203 are provided on the sealing wire 2. When the sealing wire 2 passes through the two through grooves, the one-way connection component is arranged through the connection hole 203. The one-way connection component includes a rotating shaft 105 fixedly connected to the inner wall of the accommodating chamber 103, a plug rod 106 rotatably arranged in the accommodating chamber 103, and a cone head 1061 fixedly connected to a section of the plug rod 106 away from its rotation connection. The cone head 1061 is arranged through the connection hole 203, and a limiting protrusion 104 located above the plug rod 106 and limiting the rotation of the plug rod 106 is provided on the inner wall of the accommodating chamber 103. One end of the plug rod 106 away from the cone head 1061 is rotatably connected to the rotating shaft 105, and a torsion spring is sleeved on the rotating shaft 105. The two ends of the torsion spring are respectively fixedly connected to the plug rod 106 and the inner wall of the accommodating chamber 103.

[0023] When the utility model is actually applied, the lead seal wire 2 is passed through the round hole 101 and the cross groove 102, so that the limiting piece 1 201 and the limiting piece 202 pass through the cross groove 102, and the lead seal wire 2 passes through the round hole 101, and after passing through the accommodating cavity 103, it leaves from the through groove on the other side of the lock seat 1. During the passing process, the limiting piece 1 201 and the limiting piece 202 abut against the cone head 1061 and the insertion rod 106, so that the insertion rod 106 deflects relative to the rotating shaft 105, and the torsion spring is elastically deformed, and then the elastic potential energy is accumulated. After the lead seal wire 2 stops passing through the through groove, the torsion spring can release the elastic potential energy, and then drive the insertion rod 106 to rotate relative to the rotating shaft 105, so that the cone head 1061 is inserted into the through groove. When the lead seal line 2 is pulled back, the lead seal line 2 will drive the limit piece 1 201 and the limit piece 202 to move together, and because the limit piece 1 201 and the limit piece 202 are restricted by the insertion rod 106 and the cone head 1061, the insertion rod 106 is restricted by the limit protrusion 104 after rotation, so that the insertion rod 106 cannot be further deflected, and then the cone head 1061 is separated from the connecting hole 203. In this way, after the present lock is inserted into the lock seat 1, it is not easy to be separated unless the lead seal line 2, the limit piece 1 201 and the limit piece 202 are damaged.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
