Description

Technical Field

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

[0002] To seal is to seal with lead. There are two main types of lead seals on the market: one is to lock by inserting into the keyhole, and the other is to fix by lead sealing pliers and steel stamps. The former (inserting into the keyhole to lock) has been widely used because of its convenience of operation and no need to carry additional tools. The design principle of this lead seal is to use the unidirectional conductivity of the steel wire rope in the keyhole, that is, once the steel wire rope passes through the keyhole, it cannot be easily pulled out. Therefore, if you need to open the equipment locked by the lead seal, you will destroy the lead seal itself.

[0003] However, in actual operation, since the current lead seal includes a metal spring, a mounting seat, and a number of balls arranged on the mounting seat, under normal circumstances, the mounting seat is pushed up by the metal spring, so that the balls on the mounting seat clamp the metal wire, and a strong magnet is aligned with the lower end of the lead seal to compress the spring therein, so that the balls in the lead seal no longer clamp the lead seal wire, thereby facilitating the pulling of the wire rope out of it. In this way, there is a possibility of prying, and this defect needs to be avoided.

[0004] Therefore, a pry-proof lock 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 kind of anti-pry blockade, such as Figure 1-4As shown, it includes a lock seat 2 and a sealing wire 1 fixedly connected to one end of the lock seat 2. A plurality of branch wires 101 are fixedly connected in the length direction of the sealing wire 1, and the plurality of branch wires 101 are set to be tilted outward. An inlet 201 is provided on the lock seat 2 for the sealing wire 1 and the plurality of branch wires 101 to pass through. The end of the lock seat 2 away from the inlet 201 is open, and an annular sheet 204 is fixedly connected to the open end of the lock seat 2. The inner ring opening of the annular sheet 204 is coaxially arranged with the inlet 201. A clamping assembly is slidably connected in the lock seat 2. There is a slide groove 203 in the lock seat 2. The clamping assembly is slidably connected in the slide groove 203. A metal spring 205 is embedded between the annular sheet 204 and the clamping assembly. The metal spring 205 uses the annular sheet 204 as a force point to apply a force to the clamping assembly toward the inlet 201. When the clamping assembly moves toward the end away from the sealing wire 1, the clamping assembly and the lock seat 2 clamp the branch wire 101.

[0022] A reduction groove 202 is provided at one end of the slide groove 203 facing the inlet 201, and the clamping assembly includes a mounting seat 206 slidably connected in the slide groove 203, and a plurality of ball bearings 2062. The mounting seat 206 is annular, and a plurality of inner grooves 2061 are provided on the top surface of the mounting seat 206. The inner grooves 2061 are inclined downward from the outer ring of the mounting seat 206 to the inner ring of the mounting seat 206, and the ball bearings 2062 are slidably connected in the inner grooves 2061.

[0023] The lead sealing wire 1 is arranged by tightening a plurality of metal wires, and a plurality of branch wires 101 are formed by bending the metal wires, and the metal wires are made of stainless steel.

[0024] When the utility model is blocking, the lead sealing wire 1 passes through the inlet 201 of the lock seat 2 and leaves from the annular piece 204. In this process, the lead sealing wire 1 will squeeze out a plurality of balls 2062, so that the lead sealing wire 1 passes through the mounting seat 206 with the dividing wire 101, and then passes through the annular piece 204. Then the operator only needs to hold the lead sealing wire 1 passing through the annular piece 204 to make it continue to pass through the lock seat 2. When the lead sealing wire 1 is pulled in the opposite direction, the metal spring 205 pushes up the mounting seat 206, and the mounting seat 206 moves upward with the balls 2062. Not only under the guidance of the inner wall of the shrinking groove 202, but also under the guidance of the inner groove 2061, each ball 2062 moves upward. It moves toward the center of the mounting seat 206, and the ball 2062 is also restricted by the inner wall of the shrinkage groove 202 and cannot expand outward, thereby clamping the lead sealing wire 1. It should be noted that the split wire 101 is always located in the lock seat 2. If the lock picker uses a magnet to absorb the metal spring 205 to compress the metal spring 205, causing the mounting seat 206 to move in the opposite direction, during this process, the mounting seat 206 can press the split wire 101 together with the annular sheet 204, and the split wire 101 will also be embedded between the pitches of the metal spring 205, thereby clamping the split wire 101 when the metal spring 205 is compressed, thereby making it difficult for the lead sealing wire 1 to be pulled out of the lock seat 2, thereby avoiding theft.

[0025] 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.
