[0011] A lifting component, which is detachably mounted on the connector, is used to move between the connector and the gas filter cylinder wall after the connector is connected to the sealing cover, thereby pushing the connector upward.

[0012] Furthermore, the connector includes a crossbar, and studs adapted to different models of sealing caps are respectively provided on the upper and lower sides of the crossbar, and the studs are threadedly connected to the sealing caps.

[0013] Furthermore, the number of lifting components is two, and each lifting component consists of a bolt and a nut threadedly connected to the bolt;

[0014] A strip-shaped hole is provided between the upper and lower sides of the crossbar for the bolt to move along the length of the crossbar, and the outer diameter of the nut is larger than the width of the strip-shaped hole.

[0015] Furthermore, a washer is fitted onto the bolt, and the inner diameter of the washer is not greater than the outer diameter of the nut.

[0016] Furthermore, it also includes a limiting element to restrict the rotation of the bolt;

[0017] The bolt is a hexagonal bolt, and the limiting component includes a collar. The inner diameter of the collar is not less than the maximum outer diameter of the stud. Two telescopic rods are symmetrically arranged on the collar. A positioning ring is provided at the end of the telescopic rod away from the collar. A through hole for the bolt to pass through is provided in the positioning ring. Two limiting strips for clamping the bolt head and abutting against the bolt head are symmetrically arranged at the bottom of the positioning ring.

[0018] The beneficial effects of this utility model are reflected in:

[0019] This utility model involves connecting the connector to the sealing cover that needs to be disassembled, moving the lifting component between the connector and the gas filter cylinder wall, and pushing the connector upwards through the lifting component, so that the connector drives the sealing cover to be gradually pulled out from inside the gas filter. Since the entire operation is carried out outside the gas filter, disassembly is convenient and efficient, it is not easy to damage the equipment, and it is suitable for operation in confined spaces.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0029] Please see Figure 1-4 This utility model discloses a gas filter sealing cover opening tool, comprising:

[0030] Connector 1 is used for a detachable connection with the sealing cap;

[0031] Lifting component 2 is detachably mounted on connecting component 1. After connecting component 1 is connected to the sealing cover, it is moved between connecting component 1 and the gas filter cylinder wall to push connecting component 1 upward.

[0032] This utility model involves connecting the connector 1 to the sealing cover that needs to be disassembled, moving the lifting member 2 between the connector 1 and the gas filter cylinder wall, and pushing the connector 1 upward by the lifting member 2, so that the connector 1 drives the sealing cover to be gradually pulled out from inside the gas filter. Since the entire operation is carried out outside the gas filter, the disassembly is convenient and efficient, and it is not easy to damage the equipment. It is also suitable for operation in confined spaces.

[0033] In one embodiment, the connector 1 includes a crossbar 11, and studs 12 adapted to different models of sealing caps are respectively provided on the upper and lower sides of the crossbar 11. The studs 12 are threadedly connected to the sealing caps.

[0034] This design allows for the connection of different types of sealing caps using studs 12 of varying diameters, thus improving tool applicability.

[0035] In one embodiment, there are two lifting members 2, each consisting of a bolt 21 and a nut 22 threadedly connected to the bolt 21.

[0036] A strip-shaped hole is provided between the upper and lower sides of the crossbar 11 for the bolt 21 to move along the length of the crossbar 11, and the outer diameter of the nut 22 is larger than the width of the strip-shaped hole.

[0037] With this design, after screwing the nut 22 onto the bolt 21, it is inserted into the slotted hole from below the crossbar 11, so that the nut 22 touches the crossbar 11 and the bolt 21 touches the gas filter cylinder wall. Then, the nut 22 can be rotated to move the nut 22 upward and push the crossbar 11 upward. This lifting component 2 can meet the lifting requirements. At the same time, its structure is simple and its production cost is low.

[0038] In practice, the position of the adjusting bolt 21 in the strip hole can be adjusted according to the diameter of the gas filter cylinder wall to improve the adaptability of the lifting component 2.

[0039] It should be noted that when the nut 22 rotates, it is necessary to ensure that the bolt 21 does not rotate with it, and at the same time, it is necessary to ensure that the nuts 22 on both sides move upward synchronously to improve the lifting stability of the crossbar 11.

[0040] In one embodiment, a washer is also fitted on the bolt 21, the inner diameter of which is not greater than the outer diameter of the nut 22.

[0041] This design reduces wear between the nut 22 and the crossbar 11 when the nut 22 rotates by placing a washer between the nut 22 and the crossbar 11.

[0042] In one embodiment, the gas filter cover opening tool further includes a limiting member 3 for limiting the rotation of the bolt 21;

[0043] Bolt 21 is a hexagonal bolt. The limiting component 3 includes a collar 31. The inner diameter of the collar 31 is not less than the maximum outer diameter of the stud 12. Two telescopic rods 32 are symmetrically arranged on the collar 31. A positioning ring 33 is provided at the end of the telescopic rod 32 away from the collar 31. A through hole for the bolt 21 to pass through is provided in the positioning ring 33. Two limiting strips 34 are symmetrically arranged at the bottom of the positioning ring 33 for clamping the head of the bolt 21 and abutting against the head of the bolt 21.

[0044] This design allows the collar 31 to be fitted onto the stud 12, and the limiting strip 34 to abut against both sides of the head of the bolt 21. As the nut 22 rotates, the bolt 21 can remain in its original position under the restriction of the limiting strip 34. Therefore, during disassembly, there is no need for the operator to additionally restrict the rotation of the bolt 21, further improving the convenience of operation. At the same time, due to the setting of the telescopic rod 32, the limiting member 3 can be adjusted according to the position adjustment of the bolt 21.

[0045] In practice, it is necessary to ensure that the nut 22 is located at the top of the positioning ring 33 when the tool is used, so that the operator will not interfere with the limiting part 3 when adjusting the nut 22.

[0046] It should be noted that after using this tool, first remove the nut 22 and washer from the bolt 21, then insert the bolt 21 into the slot after passing through the positioning ring 33. After that, put the washer on the end of the bolt 21 away from the head, and then tighten the nut 22 to that end. This will make the entire tool a whole and prevent parts from falling off or being lost when the tool is carried and moved.

[0047] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0048] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0049] Additionally, "multiple" refers to two or more.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
