Description

Technical Field

[0001] This utility model relates to the field of industrial equipment technology, specifically to a switch explosion-proof rubber ring puller. Background Technology

[0002] Explosion-proof rubber rings are a special sealing material widely used in various industrial equipment, pipelines, and instruments. Their main function is to ensure the normal operation of equipment and systems while effectively preventing explosive gases or dust from directly contacting the external environment, thereby reducing or even eliminating the risk of accidents such as explosions and fires.

[0003] When installing or removing explosion-proof equipment, a puller is needed to remove the explosion-proof rubber rings from the inlet and outlet devices. Existing pullers are usually pried off with a screwdriver. However, a screwdriver may not provide even pressure to pry off the explosion-proof rubber rings, which may cause the rubber rings to be scratched, torn, or deformed during the prying process. Damaged explosion-proof rubber rings may no longer provide an effective seal, thus affecting the performance and safety of the equipment. Damaged explosion-proof rubber rings may also be more difficult to replace because they may not fit tightly with other parts of the equipment.

[0004] Therefore, it is necessary to provide a new switch explosion-proof rubber ring puller to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a switch explosion-proof rubber ring puller to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a switch explosion-proof rubber ring puller, including a support rod, and further comprising:

[0007] A first connecting seat is fixed to the top of the support rod. A swing rod is rotatably connected to the inner wall of the first connecting seat. A pull rod for pulling out the explosion-proof rubber ring is provided on one side of the swing rod. A wire inlet cavity is provided on the outer side of the pull rod. The rubber ring body is provided inside the wire inlet cavity.

[0008] Preferably, one end of the support rod is fixedly connected to a first grip, and one end of the swing arm is fixedly connected to a second grip.

[0009] Preferably, a second connecting seat is rotatably connected to the outer side of the swing arm, and one side of the second connecting seat is fixedly connected to one end of the pull rod.

[0010] Preferably, the outer threaded connection of the pull rod is a limiting screw sleeve.

[0011] Preferably, a connecting frame is fixedly connected to one side of the support rod, a threaded rod is threadedly connected to the inner wall of the connecting frame, a handle is fixedly connected to one end of the threaded rod, and a limiting plate for limiting the inlet cavity is rotatably connected to the other end of the threaded rod.

[0012] Preferably, a limiting rod is fixedly connected to one side of the limiting plate, and a limiting block is fixedly connected to one end of the limiting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention inserts a pull rod into the inner hole of the rubber ring body. The limiting plate improves the stability of subsequent removal of the rubber ring body. Pressing the second gripping rod drives the swing rod to rotate inside the first connecting seat, which in turn drives the second connecting seat to rotate. The second connecting seat pulls the pull rod to move, thus pulling the limiting screw sleeve and the rubber ring body out of the inlet cavity. No damage is caused during the removal process, which can maximize the reuse of the rubber ring body and reduce repair costs. Attached Figure Description

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] Please see Figure 1-4As shown, a switch explosion-proof rubber ring puller includes a support rod 1, a first connecting seat 2 fixed to the top of the support rod 1, a swing rod 3 rotatably connected to the inner wall of the first connecting seat 2, a pull rod 4 provided on one side of the swing rod 3, the explosion-proof rubber ring can be pulled out by the pull rod 4, a wire inlet cavity 5 is provided on the outer side of the pull rod 4, and the rubber ring body 6 is provided inside the wire inlet cavity 5.

[0022] One end of the support rod 1 is fixedly connected to a first gripping rod 7, and one end of the swing rod 3 is fixedly connected to a second gripping rod 8. A second connecting seat 9 is rotatably connected to the outside of the swing rod 3. One side of the second connecting seat 9 is fixedly connected to one end of the pull rod 4. A limiting screw sleeve 10 is threadedly connected to the outside of the pull rod 4. The outer diameter of the limiting screw sleeve 10 is larger than the inner diameter of the rubber ring body 6. First, the limiting screw sleeve 10 is removed from the pull rod 4, and the pull rod 4 is inserted into the inner hole of the rubber ring body 6. Then, the limiting screw sleeve 10 is installed on the outside of the pull rod 4. Then, the second gripping rod 8 is pressed to drive the swing rod 3 to rotate inside the first connecting seat 2, which drives the second connecting seat 9 to rotate. The second connecting seat 9 pulls the pull rod 4 to move, so that the limiting screw sleeve 10 and the rubber ring body 6 can be pulled out from the inlet cavity 5. During the removal process, there will be no damage, which can maximize the reuse of the rubber ring body 6 and reduce the repair cost.

[0023] A connecting frame 11 is fixedly connected to one side of the support rod 1. A threaded rod 12 is threadedly connected to the inner wall of the connecting frame 11. A handle 13 is fixedly connected to one end of the threaded rod 12. A limiting plate 14 for limiting the inlet cavity 5 is rotatably connected to the other end of the threaded rod 12. A limiting rod 15 is fixedly connected to one side of the limiting plate 14. The outer side of the limiting rod 15 is slidably connected to the inner wall of the connecting frame 11. A limiting block 16 is fixedly connected to one end of the limiting rod 15, which clamps the connecting frame 11 to the outside of the inlet cavity 5. Rotating the handle 13 causes the threaded rod 12 to rotate, which causes the limiting plate 14 to clamp and limit the inlet cavity 5. The limiting plate 14 causes the limiting rod 15 to slide inside the connecting frame 11. The limiting plate 14 improves the stability of the subsequent removal of the rubber ring body 6.

[0024] Working principle: When using this device, first remove the limiting screw sleeve 10 from the pull rod 4, insert the pull rod 4 into the inner hole inside the rubber ring body 6, and clamp the connecting frame 11 on the outside of the inlet cavity 5. Rotate the handle 13 to drive the threaded rod 12 to rotate, which drives the limiting plate 14 to clamp and limit the inlet cavity 5. The limiting plate 14 drives the limiting rod 15 to slide inside the connecting frame 11. The limiting plate 14 improves the stability of the subsequent removal of the rubber ring body 6. Then, install the limiting screw sleeve 10 on the outside of the pull rod 4, and then press the second grip 8 to drive the swing rod 3 to rotate inside the first connecting seat 2, which drives the second connecting seat 9 to rotate. The second connecting seat 9 pulls the pull rod 4 to move, so that the limiting screw sleeve 10 and the rubber ring body 6 can be pulled out from the inlet cavity 5 without damage during the removal process. This maximizes the reuse of the rubber ring body 6 and reduces repair costs.
