Description

Technical Field

[0001] The utility model relates to the technical field of layout tools, and more specifically to an adjustable three-way layout tool. Background Art

[0002] When making tee pipe fittings, the positioning lines are marked on the pipe fittings according to the size using tools such as compasses, and then cut, grind and splice them. However, marking and marking are difficult, time-consuming, labor-intensive, and cost-intensive. Cost control is also difficult: the finished product yield is low, the marking error is large, and the finished product has poor aesthetics.

[0003] In the prior art, patent CN214893310U provides a three-way quick layout device, which is connected by hinges between the outer walls of adjacent sleeves. When a sleeve assembly composed of multiple sleeves is enclosed to form a closed structure, the two ends of the chain buckle are respectively inserted into the two sleeves at the end of the sleeve assembly, and a positioning pin is inserted in the sleeve. The lower ends of the multiple positioning pins abut against the outer wall of the overlapped pipe wall. The pipe to be processed is removed, and the sleeve assembly is slid to the rear side. A mark is made on the lower end of each positioning pin just on the outer wall of the pipe to be processed, and then the layout and cutting of the three-way pipe joint are performed according to the described figure. Although the layout device can facilitate marking the outer wall of the pipe, the sleeves at both ends are connected by a U-shaped chain buckle, and the chain buckle is inserted into the hole of the sleeve, which will make it impossible to put the positioning pins into the sleeves at both ends, thereby affecting the error of the pipeline marking, and when the positioning pin moves, it is easy to move the position, and the repeatability is poor. In view of this, we propose an adjustable three-way layout tool. Utility Model Content

[0022] 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.

[0023] Embodiment 1:

[0024] See also Figure 1-4 An adjustable three-way layout tool includes a plurality of connectors 2 and a plurality of positioning needles 1. A connecting assembly is arranged on the side wall of the connector 2. The connecting assemblies on two adjacent connectors 2 can be movably connected. The connecting assembly is arranged on the side wall of the connector 2 to connect the two adjacent connectors 2 into one body, and the two adjacent connectors 2 can rotate with each other to match the diameters of different pipes 3. The connectors 2 at the outermost ends are also connected by the connecting assembly, which will not affect the insertion of the end positioning needles 1. Among them, the movable positioning needle 1 can move up and down in the single connector 2, and the needle head of the positioning needle 1 can be marked with ink.

[0025] The connecting part 2 includes a positioning tube 201, and the positioning needle 1 can move inside the positioning tube 201 along the length direction of the positioning tube 201. The connecting component is arranged on the positioning tube 201, and a slot 207 is opened on the positioning tube 201. The positioning needle 1 is freely fallen by gravity to the surface of the pipeline 3 to locate the layout point, and a rolling belt is used to tie it from the slot 207 of the positioning tube 201 to fix the position of the positioning needle 1 for repeated use.

[0026] In the present application, the connecting assembly includes a connecting column 203 and a clamping piece, and the connecting column 203 and the clamping piece are respectively arranged on both sides of the positioning tube 201. The connecting column 203 and the clamping piece on two adjacent positioning tubes 201 can be rotatably connected, so that after the multiple positioning tubes 201 are connected into one, the angle between the two adjacent positioning tubes 201 can be rotated, thereby adapting to the positioning of vertical pipes of different diameters.

[0027] In the present application, a first mounting bar 202 and a second mounting bar 204 are also provided on both sides of the positioning tube 201;

[0028] The connecting column 203 is arranged on the first mounting bar 202, and the clamping piece is arranged on the second mounting bar 204, wherein an empty slot is opened in the middle of the clamping piece, and when the connecting column 203 rotates relative to the clamping piece, the first mounting bar 202 can pass through the empty slot.

[0029] In the present application, the clamping parts include cylindrical cylinder A205 and cylindrical cylinder B206, and the connecting column 203 can pass through the cylindrical cylinder A205 and cylindrical cylinder B206. The cylindrical cylinder A205 is provided with an opening along its length direction. The setting of the opening makes it convenient for the connecting column 203 to be inserted into the cylindrical cylinder A205 and cylindrical cylinder B206. The first mounting bar 202 passes through the opening. The cylindrical cylinder A205 and cylindrical cylinder B206 are respectively arranged near the two ends of the second mounting bar 204, and the cylindrical cylinder A205 and cylindrical cylinder B206 respectively fix the two ends of the connecting column 203.

[0030] In the present application, the bottom surface of the first mounting strip 202 is flush with the top surface of the cylindrical tube B206, and there is a gap between the top surface of the first mounting strip 202 and the bottom surface of the cylindrical tube A205. The first mounting strip 202 can slide along the opening of the cylindrical tube A205. When the first mounting strip 202 is located on the top surface of the cylindrical tube B206, the cylindrical tube B206 limits the vertical position of the first mounting strip 202, and the top surface of the first mounting strip 202 is located below the bottom surface of the cylindrical tube A205, thereby facilitating the adjustment of the angle between two adjacent positioning tubes 201.

[0031] In the present application, two groups of connection components are arranged on each positioning tube 201, and the two groups of connection components are arranged at positions near both ends of the positioning tube 201, so as to facilitate the rotational connection at the end positions of two adjacent positioning tubes 201.

[0032] Working principle: Select a suitable number of positioning tubes 201 for splicing to ensure that they just surround the vertical pipe. If an integer number of single components cannot just wrap the pipe, install U-shaped clips to fix the connecting components at both ends of the two outermost positioning tubes 201 to ensure that the positioning tubes 201 are in close contact with the pipe. Then let the positioning needle 1 fall freely by gravity to the positioning point on the surface of the main pipe, and use a rolling belt or the like to tie it from the notch 207 of the positioning tube 201 to fix the position of the positioning needle 1 for repeated use.
