Problems solved by technology

But there are also shortcomings. When the special-shaped collar clamps the jacket and the nut, even the staff of the gas company can no longer disassemble it normally. It is a one-time use. If it is to be dismantled, even the meter may be scrapped. , poor utilization of raw materials
Especially in some occasions that require frequent maintenance and disassembly, the anti-theft joint is not competent

Embodiment Construction

[0025] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0026] Such as figure 1 As shown, the pipeline anti-theft joint includes an outer body 1, a nut 2, and a joint body 3. The joint body 3 is threaded inside the nut 2 , and the outer body 1 is sheathed on the outside of the nut 2 and the joint body 3 .

[0027] Specifically, the inner side of one end surface of the nut 2 has a blocking edge 2a, and a through hole is formed in the middle of the blocking edge 2a. The joint body 3 is tubular and pierced inside the nut 2, with one end protruding out of the nut 2. The joint body 3 has an annular shoulder 3a on which the retaining edge 2a is fastened. The shoulder 3a is located inside the nut 2 and The nut 2 cannot be disengaged from the side of the rim 2a. A seal 10 is provide...

Abstract

The invention provides a theftproof joint of a pipeline, which belongs to the machinery technical field and solves the technical problem that the prior theftproof meter joint can not be repeatedly used. The theftproof joint of the pipeline comprises a cylindrical outer sleeve body, a nut and a tubular joint body, wherein an inner side surface of one end of the nut is provided with a retaining edge, the joint body penetrates in the nut and is provided with an annular convex shoulder, the retaining edge is buckled on the annular convex shoulder, the outer sleeve body is arranged outside the nutand the joint body, a limiting mechanism for axially fixing the outer sleeve body is arranged between the outer sleeve body and the joint body, the outer sleeve body is provided with an unlocking tool, and the limiting function of the limiting mechanism can be released to enable the joint body to slide on the joint body when the unlocking tool is inserted into an unlock jack. The theftproof jointof the pipeline has the advantages of simple structure, reasonable design, and can be repeatedly assembled and disassembled through the special unlock tool.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an anti-theft joint, in particular to an anti-theft joint for pipelines. Background technique [0002] At present, daily necessities such as gas and water used by families in cities are transported through pipelines, and the gas or water consumed by a family is counted by meters installed on the pipelines. Existing metering meters for pipeline gas, natural gas or water are connected to pipelines through meter joints, and the meter joints are connected to pipelines through a pipeline joint device. If there is no reliable anti-theft measure, the meter is easy to be disassembled by some users without authorization, or the speed of the meter is slowed down or reversed and reversed to count by improper means, so as to achieve the purpose of stealing gas, natural gas or water. This situation not only causes great economic losses to the management department, but also has potential safe...
