Description

Technical Field

[0001] The utility model relates to the field of general tools, in particular to a pipeline stepless locking tool. Background Art

[0002] The locking of round pipe fittings has always been a major problem in the field of general tools. That is, if the locking is not possible, round pipe fittings with threaded mouths are difficult to connect and tighten. To address this problem, an additional external hexagonal screw sleeve device is generally configured as a connector for double-threaded pipe fittings, and the pipe fittings are connected. However, this form of assembly is not applicable in some areas, such as the connection of pipe fittings such as water pipe connectors in home decoration environments. It is especially common that the edges and corners of rusted external hexagonal screw sleeves become smooth after repeated twisting, and traditional pipe clamps and wrench-type equipment are also unable to fully lock the relevant connectors. There is currently a lack of corresponding solutions to this problem. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a pipeline stepless locking tool that is suitable for a variety of pipe diameters and outer diameters of connector sizes, realizes stepless locking, and fully locks the outside of the pipe or connector, which is particularly suitable for operations such as pipeline maintenance and non-standard pipe connection.

[0004] The device includes a gripping handle, which is a hand-held rod for operators and is also an assembly base of the device;

[0005] A fork-type support is integrally provided on the upper part of the gripping handle, and the fork-type support is composed of two mirror-symmetrical rods, and teeth are densely arrayed on opposite sides of the two rods;

[0006] Chain assembly grooves are also provided on the two rods opposite to each other;

[0007] A chain is arranged on one side of the gripping handle, and a screw rod is rotatably arranged at the tail end of the chain; a screw sleeve is arranged on the other side of the gripping handle.

[0008] The effect achieved in this way is that the fork-type support is against one side of the pipe fitting or the connecting piece, and its chain part passes through the chain assembly grooves on the two rods in sequence, and the screw part is screwed into the threaded sleeve to form a coil for the pipe fitting; the screw is rotated to displace it toward the bottom of the gripping handle, forming a full locking of the pipe or the connecting piece by the fork-type support and the chain.

[0009] The beneficial effects of the utility model are as follows: the utility model solves the problem of inconvenient locking of pipe fittings, and fully locks the pipe fittings and the multilateral connectors by using the fork-type support and the matching chain, and fully locks the related structural parts in a ring-type, and is particularly suitable for the assembly and removal of round pipes and rusted connectors. The equipment has a simple structure, low cost, and great market promotion value. Description of the Drawings

[0017] The realization of the object, functional features and advantages of the present utility model will be further described with reference to the embodiments and the accompanying drawings. Detailed Embodiments

[0018] Referring to Figure 1 and Figure 2 , a stepless pipe locking tool according to the present utility model includes a holding handle 2. The holding handle 2 is a rod held by an operator and is also a basic assembly part of this device;

[0019] A fork - type support 1 is integrally provided on the upper part of the holding handle 2. The fork - type support 1 is composed of two mirror - symmetric rods, and a dense array of teeth is provided on the opposite side of the two rods;

[0020] Chain assembly through - slots 8 are also oppositely provided on the two rods;

[0021] A chain 5 is provided on one side of the holding handle 2, and a screw 6 is rotatably provided at the end of the chain 5; a sleeve 3 is provided on the other side of the holding handle 2.

[0022] The achieved effect is that the fork - type support 1 abuts against one side of a pipe fitting or a connector. The chain 5 part sequentially passes through the chain assembly through - slots 8 on the two rods, and the screw 6 part is screwed into the sleeve 3 to form a coil around the pipe fitting. Rotating the screw 6 to displace it towards the bottom of the holding handle 2 forms a full locking of the pipe or connector by the cooperation of the fork - type support 1 and the chain 5.

[0023] Example 1. Refer to the accompanying drawings of the specification Figure 1 , and the included angle between the two rods of the fork - type support 1 is 60°.

[0024] The achieved effect is that for the most widely used regular hexagonal connectors, the two rods are fitted to the two sides of the sleeve 3. Specifically, for external hexagonal connectors such as rusty regular hexagonal bolts, the device can fully lock onto them.

[0025] Example 2. Refer to the accompanying drawings of the specification Figure 2 , the fork - type support 1 includes a curved bottom support and guard plates integrally extended from the two edges of the curved bottom support, and the two guard plates are horizontally arranged.

[0026] The achieved effect is that the device is applied to common pipe fittings such as round pipes or spline pipes, and a full lock on the pipe fittings is formed by the cooperation of the fork - type support 1 and the chain 5.

[0027] Example 3. Refer to the accompanying drawings of the specification Figure 3 , a basic assembly ring 7 is arranged on one side of the holding handle 2, a spring buckle 4 is arranged inside the basic assembly ring 7, and the spring buckle 4 is connected to the chain 5.

[0028] The achieved effect is that the available length, or rather the applicable length, of the chain 5 can be adjusted at any time, and it is also convenient for the quick locking of the screw 6.

[0029] Furthermore, the tail of the screw 6 is integrally connected to a twist part in the form of an external hexagon.

[0030] The achieved effect is that it is convenient for the self - twisting adjustment of the screw 6.
