Description

Technical Field

[0001] The utility model belongs to the technical field of disassembly equipment, and in particular relates to a sealing plug disassembly device. Background Art

[0002] In many devices, in order to ensure the tightness of the internal space of the equipment, some through holes need to be sealed with sealing plugs, such as the inlet and outlet of the tank. Usually, when performing the sealing operation, the sealing plug is directly inserted into the through hole, which plays a good sealing function. However, when the sealing plug needs to be pulled out, it is difficult. The sealing plug fits the through hole so well that the operator cannot pull it out directly by hand. Therefore, it is necessary to assist with the removal of the disassembly tool.

[0003] At present, the commonly used sealing plug removal tools mostly adopt a seesaw structure, using the end of the seesaw to remove from the edge of the sealing plug and support the seesaw through the edge of the through hole to lift the sealing plug out; or screw into the sealing plug and then pull it out. However, both methods will cause different degrees of damage to the sealing plug body and are time-consuming and laborious to use. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art methods, the purpose of the utility model is to provide a sealing plug removal device, which can quickly and easily pull out the sealing plug without causing damage to the sealing plug.

[0005] In order to achieve the above purpose, the utility model adopts a technical solution: a sealing plug disassembly device, comprising:

[0006] The sealing plug cover is used to cover the sealing plug and completely place the exposed top of the sealing plug inside the cover;

[0007] and an air extraction device, which is located above the sealing plug cover body, and an air extraction end is connected to the interior of the sealing plug cover body.

[0008] Furthermore, the sealing plug cover body adopts a hollow cylinder, the internal hollow space constitutes a space for extracting the sealing plug, the exhaust end is connected to the hollow space inside the hollow cylinder, and the bottom edge of the hollow cylinder and the edge of the through hole outside the sealing plug are physically fitted to each other.

[0009] Furthermore, a sealing ring is arranged at the bottom edge of the hollow cylinder.

[0010] Furthermore, the vacuum device adopts an electric vacuum pump.

[0011] Furthermore, the electric vacuum pump comprises: a cylinder and a piston in the cylinder and slidingly matched with the cylinder; the cylinder and the piston enclose an air extraction space; and the piston is driven by a motor.

[0012] Furthermore, a mobile power source is arranged on the electric vacuum pump, and the mobile power source supplies power to the electric vacuum pump.

[0013] The beneficial effects of adopting this technical solution are:

[0014] The sealing plug disassembly device of the utility model utilizes a sealing plug cover body, which is used to cover the sealing plug, and the exposed top of the sealing plug is completely placed in the cover body; and the air is sucked out by a vacuum device, so that a negative pressure is generated inside the sealing plug cover body, thereby sucking out the sealing plug. The proposed sealing plug disassembly device utilizes air pressure to suck out, and there is no entity directly contacting the sealing plug body, which will not cause damage to the sealing plug, so that the sealing plug can be reused. In addition, the device is easy to use, and the operator does not need to use much force to complete the removal of the sealing plug, which saves time and effort. BRIEF DESCRIPTION OF THE DRAWINGS
