Description

Technical Field

[0001] The invention relates to the technical field of cable stripping, in particular to a clamp-shaped heating tool. Background Art

[0002] Cables are mainly composed of one or more mutually insulated conductors and an outer insulating protective layer, and are used to transmit electricity or information from one place to another. In daily cable connection and maintenance, it is necessary to peel off the outer insulating protective layer to expose the conductor for easy operation.

[0003] During the cable stripping process, wire strippers are often used to press and cut the protective insulating sleeve and then pull it out and strip it. However, in harsh environments, such as cold winter weather, the insulating sleeve hardens due to weather reasons, and the commonly used wire strippers cannot quickly and safely strip it, which is not only inefficient, but also does not guarantee the safety of construction workers.

[0004] In the prior art, attempts have been made to add a heating device to the jaws of the wire stripper to locally heat the wire when stripping it to soften the insulation sleeve and speed up the stripping process. However, for cables of different diameters, the local heating effect is not obvious, and it is still necessary to heat the outer side of the insulation sleeve for a long time multiple times to achieve the stripping conditions. This is inefficient, and the heating range of the coating cannot be easily and quickly adjusted according to the diameter of the cable, so it is less practical. Summary of the invention

DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar parts or parts having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection, it can be a mechanical connection or an electrical connection, it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In the description of the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include the first feature being in direct contact with the second feature, or may include the first feature being in contact with the second feature through another feature between them instead of being in direct contact. Moreover, a first feature being "above", "above" and "above" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0035] Cables are generally made up of an outer insulating protective layer supporting one or more insulated conductors inside. In daily cable maintenance operations, the outer insulating protective layer needs to be peeled off to expose the conductors for easy operation. However, in some harsh environments, such as the cold environment in winter, the insulating sleeve hardens and needs to be heated and softened so that it can be peeled off as soon as possible without harming the operators. Existing technical centers can only achieve local heating for softening the insulating sleeve, which not only has an unobvious effect, but also has extremely low work efficiency. When the cable diameter changes, the existing device cannot be adjusted adaptively, and its practicality is low.

[0036] Embodiment 1

[0037] The technical solution of this embodiment is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0038] like Figure 1-Figure 8 As shown, this embodiment provides a pliers-shaped heating tool, which mainly includes a clamping body and a heating component 30. The clamping body includes a first clamping portion 10 and a second clamping portion 20, and the second clamping portion 20 is rotatably connected to the first clamping portion 10, and a clamping space is formed between the first clamping portion 10 and the second clamping portion 20. The heating component 30 includes a heating sheet 31 and a reel 32, one end of the heating sheet 31 is connected to the first clamping portion 10, and the other end is wound around the reel 32, and the reel 32 is arranged on the second clamping portion 20. When the second clamping portion 20 rotates relative to the first clamping portion 10, the heating sheet 31 is driven to unfold or reel up through the reel 32. When the heating sheet 31 is unfolded, the component to be heated 100 can press the heating sheet 31 against the clamping space.

[0039] Thus, the first clamping part 10 and the second clamping part 20 in the clamping body can realize the clamping and releasing operation of the component to be heated 100. The heating sheet 31 is wound on the reel 32, and can be flattened or rolled up under the rotation of the reel 32, so as to change the length of the heating sheet 31 between the first clamping part 10 and the second clamping part 20, so as to realize the complete covering of the outer side of the component to be heated 100, and at the same time, the covering length can be changed in real time according to the diameter of the component to be heated 100, so as to be close to the component to be heated 100, and ensure that the outer insulating sleeve of the component to be heated 100 is completely covered and heated by the heating sheet 31. The reel 32 is rotatably arranged on the second clamping part 20, and can move relative to the first clamping part 10 under the drive of the second clamping part 20, and rotates under the action of the fixing of the heating sheet 31 and the first clamping part 10, so as to further realize the flattening or rolling of the heating sheet 31, and complete the covering and heating of the component to be heated 100.

[0040] The overall structure of the clamp-shaped heating tool of this embodiment is described below.

[0041] like Figure 1 As shown, the pliers-shaped heating tool of this embodiment includes a clamping body and a heating component 30, wherein the clamping body includes a first clamping portion 10 and a second clamping portion 20. The first clamping portion 10 and the second clamping portion 20 are rotatably connected to form a clamping space, and the two ends of the heating component 30 are respectively connected to the first clamping portion 10 and the second clamping portion 20.

[0042] A clamping space is formed between the first clamping portion 10 and the second clamping portion 20, and the heating component 30 can extend in the clamping space to wrap the component to be heated 100. In this embodiment, the clamping space is arranged to pass through along the rotation axis direction of the first clamping portion 10 and the second clamping portion 20, so as to provide a heating space for the component to be heated 100, and also ensure that during the heating process, the component to be heated 100 is covered and limited in position in the clamping space by the first clamping portion 10, the second clamping portion 20 and the heating component 30, so as not to cause safety problems such as burns to the operators.

[0043] like Figure 2 As shown, the first clamping portion 10 includes a first clamping body 11 , a heating switch 12 and a first handle 13 , wherein the first handle 13 includes a shell 131 and a capping cylinder 132 .

[0044] Optionally, one end of the first clamping body 11 is connected to the first handle 13, and the other end is connected to the heating component 30, and the first clamping body 11 is provided with a first extension end, which is rotatably connected to the second clamping portion 20. The multi-end connection of the first clamping body 11 simplifies the structure of the heating tool parts and improves the utilization rate.

[0045] In this embodiment, the first clamping body 11 is configured as an arc-shaped heat-resistant structure and is provided with a first clamping groove, so that when the component 100 to be heated is heated in the clamping space, the first clamping body 11 is not easy to melt and damage the tool due to high temperature, thereby avoiding other safety issues such as burns to operators.

[0046] Optionally, a first adapter hole is provided at one end of the first clamping body 11 connected to the heating component 30, and a second adapter hole is provided at the first extension end. The first pin is passed through the first adapter hole and connected to the heating component 30, and the second pin is passed through the second adapter hole and rotatably connected to the second clamping part 20. The first pin and the second pin are detachably connected to the first clamping body 11, which is convenient for daily maintenance and replacement of the heating component 30 and the second clamping part 20, and prolongs the service life of the tool.

[0047] like Figure 2 As shown, the heating switch 12 is provided on the first handle 13, connected to the heating component 30, and configured to control the on-off of the heating circuit of the heating component 30. Optionally, the heating switch 12 is provided with a switch button, and the circuit connection between the switch button and the heating component 30 belongs to the conventional operation in the art, which will not be described here.

[0048] Specifically, the heating switch 12 is provided with two adjustment positions, on and off. When in the on position, the heating circuit of the heating component 30 is connected, and the heating component 30 generates heat; when in the off position, the heating circuit of the heating component 30 is disconnected, and the heating component 30 stops generating heat. In other embodiments, the heating switch 12 can also be set to multiple positions as needed, so that the heating component 30 heats the component 100 to different temperatures, thereby reducing energy waste and improving operation efficiency.

[0049] Furthermore, the first handle 13 includes a housing 131 and a power source, the power source is disposed in the housing 131, and the power source is connected to the heating component 30 through the heating switch 12. The housing 131 is configured as a cylindrical structure, and one end is configured as an opening, so that the power source can be placed or taken out from the opening end. Optionally, an insulating anti-slip material structure is fixed to the outside of the housing 131 to avoid the risk of electric shock and tool falling off during use by operators.

[0050] In this embodiment, the power source is configured as a detachable battery, and the connection between the battery and the heating switch 12 is a conventional configuration, which will not be described in detail herein. The power source is detachably configured in the housing 131, which improves the portability and simplicity of the pliers-shaped heating tool in this embodiment, and facilitates storage and maintenance.

[0051] Optionally, the first handle 13 further includes a capping cylinder 132, which is detachably connected to the housing 131 and is configured as a capping power source. In this embodiment, the capping cylinder 132 is also configured as a cylindrical structure, and an insulating anti-slip material structure is fixedly connected to the outer side, and is configured as a snap-on connection with the housing 131. In other embodiments, the capping cylinder 132 and the housing 131 can also be configured as other connection modes such as plug-in.

[0052] Specifically, the capping cylinder 132 is detachably connected to the open end of the housing 131, so that the power supply is completely capped and isolated from the external environment to prevent the power supply from being damaged.

[0053] like Figure 2 As shown, the second clamping portion 20 includes a second clamping body 21 and a second handle 22 .

[0054] Optionally, one end of the second clamping body 21 is connected to the second handle 22, and the other end is connected to the heating component 30, and a second extension end is provided on the second clamping body 21, and the second extension end is rotatably connected to the first extension end. In this way, the second clamping body 21 is connected in multiple directions, the structure of the heating tool parts is simplified, and the utilization rate is improved.

[0055] In this embodiment, the second clamping body 21 is configured as an arc-shaped heat-resistant structure and is provided with a second clamping groove, and a clamping space is formed between the first clamping groove and the second clamping groove. The provision of the clamping space facilitates the effective heating of the heated component 100 during the clamping process, and the arc-shaped heat-resistant structure makes it difficult for the second clamping body 21 to melt and damage the tool due to high temperature, thereby avoiding other safety issues such as burns to operators.

[0056] Optionally, the end of the second clamping body 21 connected to the heating component 30 is provided with a third adapter hole, and the second extension end is provided with a fourth adapter hole. The second pin is sequentially inserted into the second adapter hole and the fourth adapter hole to rotatably connect the first clamping body 11 and the second clamping body 21.

[0057] Furthermore, in this embodiment, when the operator holds the first handle 13 and the second handle 22, and the first handle 13 and the second handle 22 are forced to move closer, the clamping space is expanded, and the heating component 30 is stretched and unfolded; when the first handle 13 and the second handle 22 are forced to move away, the clamping space is reduced, and the heating component 30 is retracted and rolled up. This makes it easier for the operator to apply force to complete clamping or loosening of the component to be heated 100.

[0058] like Figure 2 As shown, the heating component 30 includes a heating sheet 31 and a reel 32 .

[0059] One end of the heating sheet 31 is connected to one end of the first clamping body 11 of the first clamping portion 10, and the other end is wound on the reel 32. Specifically, the heating sheet 31 is connected to one end of the first clamping body 11 provided with the first adapter hole, and is connected to the heating switch 12, so as to realize the passage connection of the heating circuit.

[0060] Optionally, the length of the heating plate 31 is not less than the circumference of the component to be heated 100 so as to completely cover and heat the components to be heated 100 of different diameters in the circumferential direction, thereby improving the heating effect.

[0061] like Figure 3 As shown, the heating plate 31 includes a connecting piece 311 and a heating component 312 .

[0062] In this embodiment, along the length direction of the heating plate 31, two connecting members 311 are respectively arranged at both ends of the heating component 312, and are respectively connected to the first clamping portion 10 and the reel 32. Specifically, the connecting member 311 is arranged as a square frame, and the two square frames are connected to both ends of the heating component 312.

[0063] Furthermore, the connecting member 311 is provided with a wire, which is respectively connected to the heating switch 12 and the heating component 312 to form a heating circuit. The heating switch 12 is used to switch the circuit on and off, so that the heating component 312 can generate heat to heat the component 100 to be heated.

[0064] Optionally, the first pin is passed through the first adapter hole to connect the first clamping body 11 and a connecting piece 311 to achieve a detachable connection between the first clamping portion 10 and the heating component 30 .

[0065] Optionally, the heating component 312 is configured to heat the component to be heated 100 . In this embodiment, the heating component 312 is configured as an electric heating element. In other embodiments, the heating component 312 may also be configured as other structures such as a magnetic thermal induction element.

[0066] like Figure 5 As shown, the reel 32 includes a fixed shaft 321 , a bearing 322 , a reset member 323 and a roller 324 .

[0067] Specifically, the fixed shaft 321 is fixedly connected to the second clamping part 20, the bearing 322 is sleeved on the fixed shaft 321, and connected to the inner wall of the roller 324, and the outer wall of the roller 324 is connected to the heating plate 31. In this embodiment, the fixed shaft 321 passes through the third adapter hole of the second clamping body 21 and is fixedly connected to the second clamping body 21, so as to realize the connection between the heating component 30 and the second clamping part 20, and provide support for the bearing 322 and the roller 324.

[0068] Furthermore, two bearings 322 are respectively sleeved on the two ends of the fixed shaft 321, and the roller 324 is sleeved on the outer walls of the two bearings 322. Therefore, the roller 324 can rotate relative to the fixed shaft 321 under the action of the bearings 322.

[0069] A connecting piece 311 of the heating sheet 31 is fixedly connected to the outer wall of the roller 324. When the roller 324 rotates relative to the fixed shaft 321, the heating sheet 31 is unfolded or rolled up on the roller 324 under the fixing effect, so that the heating sheet 31 can be stored and the length can be adjusted.

[0070] Furthermore, if Figure 5 As shown, the reel 32 further includes a reset member 323. One end of the reset member 323 is connected to the fixed shaft 321, and the other end is connected to the roller 324. The reset member 323 can drive the roller 324 to rotate and reel up the heating sheet 31.

[0071] Optionally, the reset member 323 is configured as a coil spring, and other elastic structures may also be selected in other embodiments. Thus, under the action of the coil spring, the heating sheet 31 can be automatically rolled up on the roller 324, and can be stored in time to avoid damage.

[0072] like Figure 6-8 As shown, the specific method of using the clamp-shaped heating tool in this embodiment is as follows:

[0073] First, the operator holds the first handle 13 and the second handle 22 and applies force thereto, so that the reel 32 moves with the second clamping body 21, and the heating sheet 31 is unfolded on the reel 32;

[0074] Then, after the heating sheet 31 is unfolded to a proper length, the component to be heated 100 is placed against the heating sheet 31, gradually abutting against the heating sheet 31 from the outside of the clamping space to the inside of the clamping space;

[0075] Finally, when the heated component 100 is gradually covered by the heating sheet 31, the operator stops applying force to the first handle 13 and the second handle 22, and the heating sheet 31 completely covers the outside of the heated component 100 and limits it in the clamping space, and turns on the heating switch 12, so that the heating circuit is connected and the heating sheet 31 heats it;

[0076] After the heating is finished, the heating switch 12 is turned off, and force is applied to the first handle 13 and the second handle 22 again to take out the component 100 to be heated.

[0077] Embodiment 2

[0078] This embodiment provides a pliers-shaped heating tool, wherein the components identical or corresponding to those in the first embodiment are marked with the same reference numerals as those in the first embodiment. For the sake of simplicity, only the differences between the second embodiment and the first embodiment are described. The differences are:

[0079] like Figure 4 As shown, the heating component 312 is provided with a heat-resistant cloth 3121 and a heating element 3122. Specifically, along the thickness direction of the heating component 312, the heating element 3122 is sandwiched between two heat-resistant cloths 3121. In this embodiment, the heat-resistant cloth 3121 is set as a heat-resistant plastic cloth, and the heating element 3122 is set as a metal wire. The setting of the heat-resistant cloth 3121 can not only transfer the heat of the heating element 3122 to the component to be heated 100, but also protect the heating element 3122. At the same time, the heat-resistant cloth 3121 and the heating element 3122 are both flexible, which is convenient for winding on the roller 324.

[0080] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
