[0029] As shown in Figures 1-5 The utility model discloses a kind of pressure sensitive resistance components with heat dissipation function, including pressure sensitive resistance main body 1 and two pins 5, pressure sensitive resistance main body 1 outer circle is equipped with installation groove 2, the inside of installation groove 2 is equipped with heat conduction plate 3, the outer circle of heat conduction plate 3 is equipped with multiple radiating fins 4, the bottom end of pin 5 is fixedly connected with conducting ring 6, the inside of conducting ring 6 is movably equipped with first conducting rod 7, the bottom end of first conducting rod 7 is fixedly connected with lifting assembly 8, and the lifting assembly 8 is used to adjust the installation height of pressure sensitive resistance main body 1.

[0030] As shown in Figure 5 Lifting assembly 8 includes second conducting rod 801 fixedly connected with first conducting rod 7, the bottom end of second conducting rod 801 is fixedly connected with conducting block 802, the outside of conducting block 802 is movably equipped with conducting sleeve pipe 803, the side top of conducting sleeve pipe 803 is fixedly connected with side plate 804, the inside of side plate 804 is movably equipped with movable rod 805, the end of movable rod 805 close to second conducting rod 801 is fixedly connected with rubber extrusion block 806, spring 807 equipped outside movable rod 805 is fixedly connected between rubber extrusion block 806 and side plate 804, spring 807 extrudes rubber extrusion block 806 so that it is closely attached to the surface of second conducting rod 801, so that the height of conducting sleeve pipe 803 can be positioned, and conducting sleeve pipe 803 can be lifted and slid outside conducting block 802.

[0031] As shown in Figure 5 Side plate 804 is L-shaped structure, and the movable hole is formed in side plate 804, and movable rod 805 penetrates movable hole, and the end of movable rod 805 away from rubber extrusion block 806 is fixedly connected with limiting block, and limiting block facilitates manual pulling of staff.

[0035] Working principle: The heat-conducting plate 3 conducts heat to the varistor body 1, and then multiple heat sinks 4 quickly dissipate the heat on the heat-conducting plate 3. This accelerates the heat dissipation of the varistor body 1, which is beneficial to its safety. When installing the varistor body 1, the conductive sleeve 803 can be manually pulled up and down and slide outside the conductive block 802. Meanwhile, the spring 807 squeezes the rubber compression block 806 to make it fit tightly against the surface of the second conductive rod 801. This can position the height of the conductive sleeve 803. At the same time, the conductive ring 6 can be adjusted to deflect outside the first conductive rod 7, thereby adjusting the tilt angle of the varistor body 1.
