[0018] The utility model will be further described below in conjunction with the accompanying drawings.

[0019] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the utility model is a pipeline marking auxiliary tool, and its structure includes a holding frame 1, an operating frame 3, an elastic member and a strip 4.

[0020] The front part of the holding frame 1 is connected to the front part of the operating frame 3 through the rotating shaft 2. The operating frame 3 can rotate relative to the holding frame 1 around the rotating shaft 2. One end of the strip 4 is fixed on the holding frame 1. The strip 4 extends outward from the front end of the holding frame 1. The length of the strip 4 can be determined as needed. A clamping plate 7 is arranged at the front end of the operating frame 3. The clamping plate 7 rotates around the rotating shaft 2 together with the operating frame 3. An elastic member is arranged between the holding frame 1 and the operating frame 3. The elastic member is used to drive the operating frame 3 to rotate around the rotating shaft 2 so that the clamping plate 7 approaches the front end face of the holding frame 1 to clamp the strip 4. When the rear end of the operating frame 3 approaches the holding frame 1, the clamping plate 7 moves away from the front end face of the holding frame 1 and compresses the elastic member. Under the action of the restoring force of the elastic member, the operating frame 3 rotates around the rotating shaft 2, so that the clamping plate 7 approaches the front end face of the holding frame 1. A through hole 6 is provided at the top of the operating frame 3. The extended strip 4 needs to be reinserted between the clamping plate 7 and the front end surface of the holding frame 1 after it has passed through the pipe. The end of the strip 4 is passed through the through hole 6 to extend outward for the operator to pull.

[0021] The elastic member is a compression spring 5 or a torsion spring. When the elastic member is a compression spring 5, it is located in the middle or rear of the holding frame 1 and the operating frame 3. When the rear end of the operating frame 3 is close to the holding frame 1, the compression spring 5 is compressed. The compressed spring has a tendency to drive the operating frame 3 to rotate around the rotating shaft 2 and move the rear end of the operating frame 3 away from the holding frame 1. When the elastic member is a torsion spring, the torsion spring is located on the rotating shaft 2, one arm of the torsion spring contacts the operating frame 3, and the other arm contacts the holding frame 1. When the operating frame 3 rotates around the rotating shaft 2 relative to the holding frame 1, the torsion spring is driven to be compressed and store energy. The torsion spring releases its energy to cause the operating frame 3 to rotate in the opposite direction.

[0022] In this embodiment, the elastic member is specifically a compression spring 5. In order to limit the position of the compression spring 5 during operation, an upper spring limiting shaft 10 is arranged at the top of the operating frame 3, and a lower spring limiting shaft 11 is arranged at the bottom of the holding frame 1. The upper end of the compression spring 5 is sleeved on the upper spring limiting shaft 10, and the lower end is sleeved on the lower spring limiting shaft 11. The upper spring limiting shaft 10 and the lower spring limiting shaft 11 can prevent the compression spring 5 from escaping from the holding frame 1 or the operating frame 3 during operation.

[0023] The cross section of the holding frame 1 is a U-shaped structure, and the cross section of the operating frame 3 is an inverted U-shaped structure. The operating frame 3 and the holding frame 1 are buckled together. In this embodiment, the two side panels of the operating frame 3 are located outside the two side panels of the holding frame 1. In order to avoid interference between the holding frame 1 and the operating frame 3 during the rotation process, the upper front end of the side panel of the holding frame 1 is a rounded structure, and at the same time, the lower front end of the side panel of the operating frame 3 is also a rounded structure. When the operating frame 3 rotates, the lower front end thereof will not exceed the bottom surface of the holding frame 1.

[0024] like Figure 3As shown, the angle between the clamping plate 7 and the front end surface of the operating frame 3 is an acute angle, so that the operating frame 3 only needs to rotate a small angle to make the clamping plate 7 contact with the front end surface of the holding frame 1.

[0025] At the same time, a protrusion 9 is provided at the lower end of the rear side of the clamping plate 7, through which the clamping plate 7 can contact the front end surface of the holding frame 1 in advance and ensure that a larger clamping force is used to clamp the strip 4.

[0026] In one embodiment of the utility model, a connecting plate can be provided between the clamping plate 7 and the two side plates of the operating frame 3, and the connecting plate can prevent the deformation of the clamping plate 7 and ensure that the angle between the clamping plate 7 and the front end surface of the operating frame 3 remains unchanged.

[0027] Among them, the length of the clamping plate 7 is smaller than the height of the operating frame 3. When the operating frame 3 rotates around the rotating shaft 2, the lower end of the clamping plate 7 just corresponds to the front end of the bottom plate of the holding frame 1, and the strip 4 is clamped by the clamping plate 7 and the bottom plate of the holding frame 1.

[0028] The end of the strip 4 is fixed to the front end of the holding frame 1, generally fixed to the bottom plate of the holding frame 1, and the strip 4 can be fixed to the lower surface or upper surface of the bottom plate of the holding frame 1. The strip 4 and the bottom plate of the holding frame 1 can be fixed together by screw connection, anchoring, bonding, etc.

[0029] Since the strip 4 needs to be inserted again between the clamping plate 7 and the end face of the holding frame 1 and pass through the through hole 6 after passing through the pipe once, in order to facilitate the passage of the strip 4, the through hole 6 is set at the front part of the top plate of the operating frame 3. At the same time, a guide plate 8 is set in the operating frame 3. The guide plate 8 is generally inclined. The guide plate 8 is used to guide the end of the strip 4 to extend outward through the through hole 6. The upper end of the guide plate 8 is connected to the rear end of the through hole 6. When the end of the strip 4 is inserted between the clamping plate 7 and the front end face of the holding frame 1, the end of the strip 4 moves along the guide plate 8 until it passes through the through hole 6.

[0030] The two sides of the guide plate 8 are not connected to the two side plates of the operating frame 3, leaving a certain gap for the side plates of the holding frame 1 to pass through.

[0031] The method of using the utility model is as follows: the strip 4 extending from the front end of the holding frame 1 is passed around the pipe along a predetermined position; the rear end of the operating part is pressed to open the gap between the clamping plate 7 and the front end of the holding frame 1, and the elastic member is compressed at the same time, and then the end of the strip 4 passing around the pipe is inserted into the gap between the front end of the holding frame 1 and the clamping plate 7, and the end of the strip 4 is extended outward through the through hole 6; the exposed part of the strip 4 is pulled to tighten the strip 4 so that the strip 4 is close to the outer wall of the pipe; the operating part is released to allow the elastic member to automatically recover, and under the action of the elastic member, the clamping plate 7 approaches the front end of the holding frame 1 to clamp the strip 4; the operator draws a line along the edge of the strip 4; after the line drawing is completed, the operator presses the rear end of the operating part to compress the elastic member, and again opens the gap between the clamping plate 7 and the front end of the holding frame 1, and pulls the strip 4 or the holding frame 1 to remove the strip 4 from the pipe.
