[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0017] Please combine Figures 1 to 8 The tracer connector heat shrink sleeve heating device includes a clamp body in the shape of a cross axis. The front end of the clamp body has a heating component for heating after wrapping around the heat shrink sleeve. The tail end of the clamp body has a handle 5. A storage battery 6 is detachably mounted on the handle 5. The outside of the storage battery 6 is covered with a protective shell 10 that can be inserted into the handle 5 along the axial direction of the handle 5.

[0018] It also includes a positioning component, which is triggered by inserting the protective housing 10 axially onto the handle 5 to lock the relative position of the battery 6 on the handle 5.

[0019] In practice, the tracer connector heat shrink sleeve is placed in the heating assembly of the clamp body. The clamp body, which is shaped like a cross shaft, is used to clamp the tracer connector heat shrink sleeve. With the use of the heating assembly (battery 6 provides power for the operation of the heating assembly), the heat shrink sleeve is heated. After heating is completed, the clamp body is released and the tracer wire (heat shrink sleeve) is removed from the heating assembly.

[0020] The advantage of this design is that a heating component that can surround and heat the tracer connector is added to the portable cross-axis clamp body, which can achieve uniform heating of the tracer connector in a ring. It has the advantages of uniform heating, controllable heating time and improved portability. It is particularly suitable for pipeline construction scenarios in complex terrain conditions. At the same time, the positioning component can also effectively protect the battery and facilitate its removal and replacement.

[0021] In one example, the clamp body includes two intersecting clamp arms 2, each with a handle 5 at its tail end and a jaw 1 at its front end, forming a clamping space between the two jaws 1 for circumferentially clamping and pressing the heat shrink sleeve.

[0022] Furthermore, a connecting shaft 4 is provided at the intersection of the two clamp arms 2, and a support spring 3 is provided between the clamp arms 2.

[0023] Thus, by pressing the handle 5 at the tail of the clamp arm 2, the two clamp arms 2 can be rotated synchronously in opposite directions around the connecting shaft 4, so that the two jaws 1 are brought closer to each other, and the support spring 3 is compressed and deformed (this part of the elastic deformation can be released when the pressure on the handle 5 is released later, so that the two jaws 1 can be automatically separated, so that the tracer wire (heat shrink sleeve) can be taken out from the jaws 1).

[0024] In one example, the heating assembly includes an electric heating element 101 disposed inside the jaws 1, and a push-button switch 501 disposed on the handle 5. The electric heating element 101 is electrically connected to the battery 6 via the push-button switch 501.

[0025] Thus, the heating time of the heat shrink sleeve by the electric heating element 101 can be controlled by the button switch 501, and the storage battery 6 provides power for the heating operation of the electric heating element 101.

[0026] It should be noted that the electric heating element 101 can be an electric heating plate or an electric heating film. Since the working principles of the electric heating element 101, the battery 6 and the push button switch 501 are all existing technologies, this application will not elaborate on them further.

[0027] In one example, the positioning component includes a first locking block 11 disposed on the side of the protective shell 10 facing the handle 5. The handle 5 has a mounting groove 7 for placing a battery 6. The end of the mounting groove 7 away from the jaws 1 has a first locking slot 12 that mates with the first locking block 11. The battery 6 is provided with a conductive post 8, and the mounting groove 7 has a conductive insertion hole 9 that mates with the conductive post 8. The protective shell 10 can completely cover the battery 6 in the mounting groove 7, and the first locking block 11 abuts against the end face of the battery 6 away from the conductive post 8.

[0028] Thus, the battery 6 can be initially placed on the handle 5 through the mounting slot 7. The conductive post 8 on the battery 6 is then inserted into the conductive socket 9 (the conductive socket 9 contains an electrical connector that makes contact with the conductive post 8 and is electrically connected to the push button switch 501 and the electric heating element 101; since the circuit connection method and working principle between the electrical connector, the push button switch 501, and the electric heating element 101 are all existing technologies, this application will not elaborate further on them), completing the circuit connection of the battery 6. Subsequently, the protective shell 10 is inserted into the handle 5 along the axial direction of the handle 5, so that the first locking block 11 is locked in the first locking slot 12, completing the position fixation of the protective shell 10 on the handle 5. At the same time, the first locking block 11 can abut against the tail of the battery 6, so that the conductive post 8 of the battery 6 is stably inserted into the conductive socket 9, avoiding poor contact. In addition, at this time, the protective shell 10 completely covers the mounting slot 7 to protect the battery 6.

[0029] In one example, a second locking block 13 is provided on the side of the protective shell 10 near the heating component, a second locking groove 14 that mates with the second locking block 13 is provided on the mounting groove 7, a locking rod 17 perpendicular to the second locking block 13 is inserted into the outer wall of the handle 5, and a locking hole 18 that mates with the locking rod 17 is provided on the outer wall of the second locking block 13.

[0030] Thus, when the protective shell 10 is installed on the handle 5, the locking hole 18 corresponds exactly to the position of the locking rod 17. By driving the locking rod 17 to engage with the locking hole 18, the relative position of the protective shell 10 on the handle 5 is locked.

[0031] In one example, a groove 15 is provided on the outer wall of the handle 5, and a fixed plate 16 is fixed inside the groove 15. The locking rod 17 slides through the fixed plate 16, and a slider 19 that mates with the groove 15 is sleeved and fixed on the outer side of the locking rod 17. A return spring 20 is sleeved on the outer side of the locking rod 17, and the two ends of the return spring 20 are respectively connected to the outer wall of the slider 19 and the plate wall of the fixed plate 16. A pressure plate 21 is provided on the side of the protective shell 10 near the heating component. The pressure plate 21 has an inclined surface 22 that contacts and engages with the end of the locking rod 17 away from the locking hole 18.

[0032] It should be noted that when the pressure plate 21 is not in contact with the locking rod 17, the return spring 20 is in a non-deformed state, one end of the locking rod 17 is detached from the locking hole 18, and the other end of the locking rod 17 protrudes out of the handle 5. When the protective shell 10 is installed on the handle 5, the inclined surface 22 of the pressure plate 21 will contact and squeeze the locking rod 17, forcing the locking rod 17 to lock into the locking hole 18. The return spring is compressed and deformed. This deformation can help the locking rod 17 to disengage from the locking hole 18 when the pressure plate 21 disengages from the locking rod 17, so that the protective shell 10 can be removed from the handle 5.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0034] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0035] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions of "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.
