DETAILED DESCRIPTION

[0025] like Figure 1 - Figure 6 As shown, the utility model provides a technical solution: a pin-type porcelain insulator, comprising a main body 1 and a mounting seat 2, a mounting structure 4 is provided on the top of the main body 1, and a fixing structure 5 is provided on the bottom of the main body 1.

[0026] The mounting structure 4 includes: a support rod 41, an auxiliary block 42, a slot 43, an auxiliary slot 44, a slider 45, a handle 46, a fixed shell 47, a reset spring 48, and a ramp block 49. The top of the main body 1 is fixedly connected with the support rod 41, and the main body 1 fixes the support rod 41. The end of the support rod 41 away from the main body 1 is fixedly connected with the auxiliary block 42, and the support rod 41 fixes the auxiliary block 42. The side wall of the auxiliary block 42 is provided with a slot 43, and the bottom of the auxiliary block 42 is provided with an auxiliary slot 44, and the auxiliary slot 44 is adapted to the top of the slider 45. The outer wall of the support rod 41 is slidably connected with the slider 45, and the slider 45 can slide along the outer wall of the support rod 41. The inner wall of the auxiliary slot 44 fits the slider 45. The top of the mounting seat 2 is fixedly connected with the fixed shell 47, and the mounting seat 2 fixes the fixed shell 47. The inner wall of 47 is slidably connected with an inclined surface block 49, and the fixed shell 47 limits the moving trajectory of the inclined surface block 49, thereby preventing the inclined surface block 49 from deflecting. The inner wall of the fixed shell 47 is fixedly connected with a return spring 48, and the fixed shell 47 fixes the return spring 48. One end of the return spring 48 away from the inner wall of the fixed shell 47 is fixedly connected to the inclined surface block 49, and the return spring 48 can drive the inclined surface block 49 to reset by its own elastic force. The inner wall of the slot 43 fits the inclined surface block 49, and the size of the slot 43 is adapted to the size of the inclined surface block 49. The outer wall of the slider 45 is fixedly connected with a handle 46, and the slider 45 can be conveniently moved by the handle 46.

[0027] The fixing structure 5 comprises: a fixing block 51, a threaded rod 52, a movable block 53, and a clamping plate 54. The fixing block 51 is fixedly connected to the bottom of the main body 1, and the main body 1 plays a fixing role on the fixing block 51. The outer wall of the fixing block 51 is penetrated by the threaded rod 52 and is rotatably connected to the penetration of the threaded rod 52. The fixing block 51 plays a supporting role on the threaded rod 52. The outer wall of the threaded rod 52 is threadedly connected to the movable block 53. The two groups of movable blocks 53 will move in opposite directions with the rotation of the threaded rod 52. The inner wall of the fixing block 51 is slidably connected to the movable block 53. The outer wall of the movable block 53 is fixedly connected to the clamping plate 54. The clamping plate 54 will move with the movement of the movable block 53, and the movable block 53 plays a fixing role on the clamping plate 54.

[0028] Working principle: by moving the main body 1 upward toward the notch on the surface of the mounting seat 2, the support rod 41 will drive the auxiliary block 42 to move upward along with the movement of the main body 1. At this time, the inclined surface at the top of the auxiliary block 42 will push the inclined surface at the bottom of the inclined surface block 49, thereby causing the inclined surface block 49 to move in the direction of the reset spring 48, so that the slot 43 can be in the same horizontal plane as the auxiliary block 42 moves. At this time, the inclined surface block 49 will be reset by the elastic force of the reset spring 48, thereby causing the inclined surface block 49 to be inserted into the slot 43. Thereby, the main body 1 is fixed on the mounting base 2. At the same time, when the main body 1 needs to be disassembled, it is only necessary to move the handle 46. At this time, the slider 45 will move upward with the movement of the handle 46, and then the slider 45 squeezes the inclined surface of the inclined surface block 49 to make the inclined surface block 49 move again in the direction of the return spring 48, so that the slider 45 is stuck in the auxiliary groove 44 at the bottom of the auxiliary block 42. At this time, the inclined surface at the bottom of the slider 45 will fit with the top of the inclined surface block 49, and then the main body 1 can be taken out from the mounting base 2 by moving the main body 1.

[0029] At the same time, the threaded rod 52 can be rotated, and the movable block 53 will slide along the inner wall of the fixed block 51 as the threaded rod 52 rotates. At this time, the clamping plate 54 will move with the movement of the movable block 53, thereby adjusting the distance between the two groups of clamping plates 54, so that the clamping plates 54 can quickly fix wires of different sizes, thereby further saving the time of installing the main body 1.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
