DETAILED DESCRIPTION

[0024] The utility model is further described below with reference to the accompanying drawings and embodiments. The directions in the description are based on the use state. The U-shaped structure of the opening below is parallel on both sides of the opening, the bottom cross section is an arc shape, and the overall shape is axially symmetrical. The fuse body plug cover separation tool described in the utility model is used to separate the fuse body plug cover similar to Figure 1 The plug cover 19 of the fuse body 20 is separated intactly.

[0025] like Figure 2 , 3 As shown, the fuse body plug cover separation tool comprises a sleeve 10 and a support seat 6 fixedly connected to a mounting seat 5. The mounting seat 5 is a base with a larger area than the sleeve 10 and the support seat 6, and is provided with a plurality of mounting holes 16 for fixed connection with the underlying foundation (see Figure 4 , 5 , 6), providing a stable base for the sleeve 10 and the support seat 6.

[0026] like Figure 4 , 5 As shown in Figures 6 and 7, the sleeve 10 is a columnar shape with the axis vertically arranged. After the slip ring 11 is put on, a movable space can be created for vertical operation. A U-shaped positioning groove 2 and a U-shaped alignment groove 1 arranged just above the positioning groove 2 and parallel to the positioning groove 2 are provided on the top of the sleeve 10. In the embodiment, the positioning groove 2 and the alignment groove 1 are both arranged horizontally. The positioning groove 2 and the alignment groove 1 are both axially symmetrical, and the axes of symmetry of the positioning groove 2 and the alignment groove 1 are both in a vertical plane. The arc bottom of the positioning groove 2 is covered by the arc bottom of the alignment groove 1 and is offset inward by 5 to 20 mm. The alignment groove 1 plays a guiding role in positioning and sliding the fuze body in, and the positioning groove 2 plays a role in embedding and locking the protruding plug eaves 18 of the plug cover 19. The horizontal surface at the height of the alignment groove 1 forms a platform, which serves as an operating platform for the fuze body to enter the operating state. During the specific operation, the fuze body 20 is arranged according to Figure 1 When the state is inverted, the plug cover 19 is in the lowest state. Therefore, the plug cover 19 can slide into the positioning slot 2 in a horizontal manner.

[0027] The U-shaped positioning groove 2 and alignment groove 1 are axially symmetrical with respect to the symmetric center plane 14. The center of the support seat 6 is set on the symmetric center plane 14 of the positioning groove 2 on one side of the mounting seat 5 and the sleeve seat 10. A support shaft 9 is horizontally set on the upper part of the support seat 6. The support shaft 9 is perpendicular to the symmetric center plane 14 of the positioning groove 2. The material removal rod 12 is connected to the support seat 6 through the support shaft 9. The front end of the material removal rod 12 is movably embedded in the clamping groove 3, and the rear part of the material removal rod 12 is a handle 7. The support shaft 9 can be fixedly connected to the support seat 6 and pivoted to the material removal rod 12. The support shaft 9 can also be fixedly connected to the material removal rod 12 and pivoted to the support seat 6.

[0028] See also Figure 2The plug cover separation operation is completed through the cooperation of the loop 11. The loop 11 is a cylinder with an open lower end and an open top plate at the upper end. The movable sleeve is arranged outside the sleeve 10, and the radial clearance between the loop 11 and the sleeve 10 is not more than 2mm.

[0029] The outer side of the loop 11 is laterally provided with a clamping groove 3. The structure of the clamping groove 3 is varied, and can be composed of a groove between a pair of convex strips, or a convex strip or a concave groove. The force-applying component is under the convex strip or in the concave groove, and the release rod 12 lifts the loop 11 in the clamping groove 3 to complete the action of removing the plug cover. Figure 2 In the embodiment, the clamping groove 3 is a linear groove dug transversely on the outer surface of the looper 11, which is easier to realize in terms of process.

[0030] Further optimization solutions, such as Figure 2 , 3 As shown, the clamping groove 3 is horizontally dug out a transverse groove on the outer surface of the loop 11, and the clamping groove 3 is provided with a pair of symmetrical central planes 14, and a pair of clamping grooves 3 are built-in with force-applying components, so that the force is more balanced and stable. The front end of the material removal rod 12 is a fork head 8 with a pair of fork rods, and the rear end is a handle 7 for applying force. The material removal rod 12 is rigid as a whole, and the pair of forks 8 are movably embedded in the pair of clamping grooves 3. The material removal rod 12 is set horizontally by default. When the handle 7 is pressed down, the pair of forks 8 rotate upward around the support shaft 9 of the material removal rod 12, so the pair of forks 8 move horizontally relative to the pair of clamping grooves 3. In addition, the end of the clamping groove 3 facing the support seat 6 is a trumpet shape that opens outward, which will not hinder the arc movement of the fork head 8. Preferably, the center line of the clamping groove 3 is lower than the axis of the support shaft 9, so that the outer end of the material removal rod 12 rises 2 to 6 degrees in the initial state. In this way, the stroke of the fork head 8 can be longer, and the distance of the lateral movement of the fork head 8 will not be too large.

[0031] In a preferred embodiment, the transmission head 4 at the front end of the fork head 8 is elliptical in shape, with the major axis being parallel to the symmetric center plane 14. The fork head 8 can be made strong and wear-resistant, and the pressing handle 7 is more effective in converting the vertical stroke of the loop 11, and the ratio of the pressing stroke to the vertical stroke of the loop 11 is more linear.

[0032] The top of the looper 11 is integrally provided with a top cover 13 with a U-shaped opening, and the U-shaped opening direction of the top cover 13 is parallel to the clamping groove 3. That is, the top U-shaped opening of the looper 11 is also symmetrical with respect to the symmetry center plane 14.

[0033] A preferred embodiment of the top cover 13 is as follows Figure 2As shown, the end face of the U-shaped opening edge arc section of the top cover 13 is a downwardly inclined inward inclined surface, and the inner diameter of the U-shaped opening edge arc section of the top cover 13 is smaller than the inner diameter of the alignment groove 1. When the plug cover 19 of the fuze body 20 slides into the locking groove 2, the U-shaped opening edge arc section of the top cover 13 contacts the side of the fuze body 20, with a smaller contact area and a larger contact pressure. The fuze body is a truncated cone with the smallest diameter of the plug cover part, which is inverted during operation. When the top cover 13 is raised, the fuze body can be lifted more effectively without sliding, thereby smoothly prying the plug cover 19 loose.

[0034] exist Figure 2 , 3 As can be seen from Figures 5 and 6, from the perspective of manufacturing process, the support seat 6 and the mounting seat 5 are manufactured separately and then fixed together during assembly. A support hole 15 is vertically arranged at the corresponding position of the mounting seat 5, and a pin groove is vertically dug out on one side of the bottom of the support hole 15 (see Figure 6 ), the center of the pin groove is on the circumference of the support hole 15, the diameter is 1 / 5 to 1 / 7 of the support hole 15, the axial length is 1 / 3 of the support hole 15, the bottom of the support seat 6 is correspondingly set to a cylindrical shape with the same diameter as the support hole 15, the positive tolerance is 0 to 0.5mm, and the corresponding pin groove position is drilled or tapped with equal height and diameter. When installing, the support seat 6 is inserted into the support hole 15, and the pin with interference fit is knocked in or the pin is threaded at this position to fix the support seat 5. Such matching is convenient for processing and connection, saves materials, and works stably and reliably.

[0035] When in use, first install all components and check whether the fixture is firmly fixed. Put the corresponding specification of the slip ring 11 on the sleeve 10, and then install the material return rod 12. When installing the material return rod 12, raise the tail of the material return rod 13, slide the fork head 8 along the clamping groove 3, align the support shaft 9 with the shaft hole of the support seat 6, and then insert the support shaft 9. When the plug cover is separated, turn over the fuse body 20 with the plug cover 19, the plug cover 19 faces downward, and the plug cover 19 slides horizontally into the positioning groove 2 and nests to the limit position, and press the handle 7 to pry the plug cover 19 loose.

[0036] The above embodiments of different parts can be used interchangeably as needed, and the preferred solution does not affect the protection scope of the utility model.
