Description
Technical Field
[0001] The utility model relates to the technical field of plasma cutting torches, and particularly relates to a plasma cutting torch handle. Background Technique
[0002] An air plasma cutting torch is a thermal cutting device. Its working principle is to use compressed air as the working gas and a high-temperature and high-speed plasma arc as the heat source to locally melt the metal to be cut, and at the same time use a high-speed air flow to blow away the melted metal to form a narrow cut. This device can be used for cutting various metal materials such as stainless steel, aluminum, copper, cast iron, and carbon steel. It not only has a fast cutting speed, a narrow cut, a smooth cut surface, a small heat-affected zone, low workpiece deformation, and simple operation, but also has a significant energy-saving effect.
[0003] In the prior art, the plasma cutting torch handle is integrally processed. In order to be applicable to many air-cooled machine models, it is necessary to process multiple handles with different interfaces, resulting in that a single handle can only be adapted to one model of air-cooled machine, with poor applicability, and subsequent frequent replacement of the handle is required, wasting time and reducing work efficiency. For this reason, this application proposes a plasma cutting torch handle. Summary of the Utility Model

Detailed implementation manners
[0023] As described in the background art, in the prior art, the plasma cutting torch handle is integrally processed. In order to be applicable to numerous air-cooled machine models, it is necessary to process multiple handles with different interfaces, resulting in that a single handle can only be adapted to one model of air-cooled machine, with poor applicability, and subsequent frequent replacement of the handle is required, wasting time and reducing work efficiency.
[0024] To solve this technical problem, the present utility model provides a plasma cutting torch handle, which is applied to a plasma cutting torch;
[0025] It includes a first handle half shell 1 and a second handle half shell 2.

[0026] A hollow sleeve 9 is sleeved outside between the first half screw barrel 6 and the second half screw barrel 7. One end inside the hollow sleeve 9 is provided with an internal thread 10, and the other end inside the hollow sleeve 9 is symmetrically provided with guide grooves 11. A guide ring 12 is slidably connected between the two guide grooves 11 inside the hollow sleeve 9. A limiting component is arranged between the outer side of the guide ring 12 and the hollow sleeve 9. A mounting frame base 16 is rotatably connected to the inner side of the guide ring 12, and a plurality of assembly joints 17 are fixedly arranged in an array on the outer side of the mounting frame base 16.

[0028] It should be noted that, without conflict, the embodiments and the features and technical solutions in the embodiments in the present utility model can be combined with each other.
[0029] It should be noted that: similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0030] Embodiment 1:
[0031] Please refer to Figures 1-4 , a plasma cutting torch handle, including a first handle half shell 1 and a second handle half shell 2. One ends of the first handle half shell 1 and the second handle half shell 2 are respectively fixed with a first half screw barrel 6 and a second half screw barrel 7. The other ends of the first handle half shell 1 and the second handle half shell 2 are respectively fixed with a socket 4 and a buckle seat 5. Since the first handle half shell 1 and the second handle half shell 2 are mutually attached, the first half screw barrel 6 and the second half screw barrel 7 are attached to each other, and the socket 4 and the buckle seat 5 are attached to each other. And the socket 4 and the buckle seat 5 are in interference fit. The attachment between the socket 4 and the buckle seat 5 is used to limit the position between the first handle half shell 1 and the second handle half shell 2. A trigger component 3 is arranged on the outer side of the first handle half shell 1;
[0032] A hollow sleeve 9 is sleeved outside between the first half screw barrel 6 and the second half screw barrel 7. One end inside the hollow sleeve 9 is provided with an internal thread 10. The hollow sleeve 9 is threadedly connected to the first half screw barrel 6 and the second half screw barrel 7 through the internal thread 10, thereby assembling and fixing between the first handle half shell 1 and the second handle half shell 2. The other end inside the hollow sleeve 9 is symmetrically provided with guide grooves 11. A guide ring 12 is slidably connected between the two guide grooves 11 inside the hollow sleeve 9. A mounting frame base 16 is rotatably connected to the inner side of the guide ring 12, and a plurality of assembly joints 17 are fixedly arranged in an array on the outer side of the mounting frame base 16;
[0033] The interior of the mounting frame base 16 is interconnected with a plurality of assembly joints 17, such that when an air-cooled plasma cutting torch of a different external model is installed and connected to a certain assembly joint 17, its wire can easily extend to the inner sides of the first handle half-shell 1 and the second handle half-shell 2 through the cooperation of the assembly joint 17 and the mounting frame base 16 with the hollow sleeve 9. In order to limit and fix the positions of the plurality of assembly joints 17, arc-shaped card slots 18 are provided inside the hollow sleeve 9 at the end far from the internal thread 10 and outside each assembly joint 17, and the outer sides of the assembly joints 17 are fitted with the arc-shaped card slots 18;
[0034] When the plurality of assembly joints 17 are respectively located inside the plurality of arc-shaped card slots 18, the mounting frame base 16 cannot rotate at this time, thus achieving the fixing effect on the assembly joints 17. When the guide ring 12 slides in a direction away from the first handle half-shell 1 and the second handle half-shell 2, the assembly joints 17 are removed from the inside of the arc-shaped card slots 18, causing the limit to fail. Therefore, in order to limit and fix the position of the guide ring 12, a limit assembly is provided between the outer side of the guide ring 12 and the hollow sleeve 9;
[0035] Specifically, sliders 13 are fixed on the outer side of the guide ring 12 and inside the two guide slots 11. The two sliders 13 are respectively slidably connected to the two guide slots 11. The limit assembly includes pull rods 14. The pull rods 14 are slidably connected to the center of the inside of the hollow sleeve 9 and outside the two guide slots 11. One ends of the two pull rods 14 are respectively slidably connected to the two sliders 13, and springs 15 are fixed between the outer sides of the other ends of each pull rod 14 and the hollow sleeve 9;
[0036] Embodiment 2:
[0037] The plasma cutting torch handle provided in Embodiment 1 is further optimized. Specifically, as Figure 3 shown, after the hollow sleeve 9 is threadedly connected to the outer sides of the first half-screw cylinder 6 and the second half-screw cylinder 7 by means of the internal thread 10, in order to further enhance the friction between the hollow sleeve 9 and the first handle half-shell 1 and the second handle half-shell 2, and thus make the assembly between the first handle half-shell 1, the second handle half-shell 2 and the hollow sleeve 9 more firm, anti-slip ring pads 8 are fixed on the ends of the first handle half-shell 1 and the second handle half-shell 2 close to the hollow sleeve 9 and outside the first half-screw cylinder 6 and the second half-screw cylinder 7. The two anti-slip ring pads 8 are in contact with each other, and the outer side of the hollow sleeve 9 is in contact with the inner sides of the two anti-slip ring pads 8;
[0038] The usage process of the plasma cutting torch handle provided by the utility model is as follows: The fitting between the socket 4 and the buckle seat 5 plays a positioning effect during the installation of the first handle half shell 1 and the second handle half shell 2, and also plays a certain limiting role in the assembly between the first handle half shell 1 and the second handle half shell 2, so that at this time, the first handle half shell 1 and the second handle half shell 2, the first half screw cylinder 6 and the second half screw cylinder 7 are mutually fitted. Then, after the hollow sleeve 9 is threadedly connected to the outer sides of the first half screw cylinder 6 and the second half screw cylinder 7 through the internal thread 10, the assembly and fixation of the first handle half shell 1 and the second handle half shell 2 are completed;
[0039] Since the orientation position of the trigger component 3 is fixed, when using this handle, a certain fitting joint 17 to be used needs to be in the same orientation as the trigger component 3, so as to facilitate the use of this handle after the fitting joint 17 is installed with an external air-cooled plasma cutting torch;
[0040] When it is necessary to replace the fitting joint 17 according to different types of cutting torches, pull the pull rod 14 to slide it out of the slider 13, and then it is convenient to slide the guide ring 12 away from the internal thread 10, so that the fitting joint 17 is moved out of the inner side of the arc-shaped card slot 18, thus facilitating the rotation of the mounting frame seat 16 to select different-diameter fitting joints 17 to be used;
[0041] After the selection is completed, align the fitting joint 17 with the trigger component 3 to make their orientations the same, and then slide the guide ring 12 back to its original position, so that the multiple fitting joints 17 return to the inner sides of the multiple arc-shaped card slots 18 again, and release the pull rod 14. Utilize the elastic characteristic of the spring 15 to drive the pull rod 14 to reset, so as to re-limit and fix the guide ring 12, thereby realizing the fixation of the positions of the multiple fitting joints 17.
