[0037] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0038] Reference Figure 1~Figure 5 , which is the first embodiment of the utility model, proposes a rubber seal rubber ring piston installation structure, including a seal 1, one end of a support member 2 is arranged in the seal 1, and there is a accommodating space 3 between the seal 1 and the support 2, and a clamping member 4 is slidably arranged at the other end of the support 2. After the clamping member 4 slides into the accommodating space 3, the clamping member 4, the support 2 and the seal 1 are abutted in sequence.

[0039] In the utility model, in order to solve the problems of difficult installation of the sealing ring, large space occupancy and low sealing in the related technology, one end of the support member 2 is placed in the sealing member 1, and then the clamping member 4 is inserted from the other end. As the clamping member 4 is inserted, the clamping member 4 enters the accommodating space 3 close to one end of the support member 2, and then the clamping member 4 in the accommodating space 3 stretches the support member 2 and the sealing member 1 to form a sealing structure.

[0040] Furthermore, the sealing member 1 is made of rubber material, and includes a sealing sleeve 101 . The sealing sleeve 101 has a cavity therein, one end of the support rod is arranged in the cavity, and a positioning boss 102 is arranged on the sealing sleeve 101 .

[0041] In the present invention, in order to install the seal 1 on the sheet metal hole, the sealing sleeve 101 is inserted into the sheet metal hole, and the positioning boss 102 is clamped on the sheet metal, so that the seal 1 can be positioned.

[0042] Furthermore, the support member 2 has a positioning ring 201 , and the sealing member 1 has an annular groove 103 . The annular groove 103 is disposed in the positioning boss 102 , and the positioning ring 201 is engaged with the annular groove 103 .

[0043] In the present invention, in order to realize the connection between the support member 2 and the sealing member 1, it is necessary to set the positioning boss 102 in the annular groove 103 to connect and support the sealing member 1 made of rubber material.

[0044] Furthermore, the support member 2 includes an expansion section 203, which is arranged in the accommodating space 3. The positioning ring 201 is located at one end of the expansion section 203 close to the positioning boss 102. The connecting section 204 is arranged at one end of the expansion section 203. The connecting section 204 has a first groove 205. After the expansion section 203 enters the accommodating space 3, the clamping member 4 abuts against the first groove 205.

[0045] In the utility model, in order to connect the entire sealing member 1, a first card groove 205 needs to be set, and the first card groove 205 is used to connect the clamping member 4. At this time, the sealing member 1, the support member 2 and the clamping member 4 become a whole, and the expansion section 203 is a plurality of triangular structures that are not connected to each other. After the expansion section 203 enters the accommodating space 3, the inclined surface faces the accommodating space 3. At this time, the clamping member 4 abuts against the first card groove 205, and the upper part of the clamping member 4 abuts against the inclined surface of the expansion section 203 and props it up, thereby forming a seal.

[0046] Furthermore, the connecting section 204 also has a second slot 206, and the expansion section 203, the first slot 205 and the second slot 206 are arranged in sequence.

[0047] In the present invention, in order to allow the sealing member 1, the connecting member and the pressing member 4 to be an integral unit even when not sealed, a second card slot 206 is provided. When the second card slot 206 and the pressing member 4 are in contact, the entire device will not enter a sealed state, but will be connected as a whole.

[0048] Furthermore, the first card slot 205 and the second card slot 206 are both multiple, and the multiple first card slots 205 and the second card slots 206 are arranged in a circular array on the connecting section 204 . The clamping member 4 has a card block 401 , and the card block 401 has multiple, and the multiple card blocks 401 are engaged with the first card slot 205 or the second card slot 206 .

[0049] In the utility model, in order to ensure that the clamping member 4 can be connected to the first card slot 205 or the second card slot 206, a clamping block 401 is required. When not in use, the clamping block 401 is connected to the second card slot 206, but the expansion section 203 is not expanded. However, the entire device has been connected to each other as a whole. When sealing, the sealing sleeve 102 is placed in the hole to be sealed, and the clamping block 401 abuts against the first card slot 205. At this time, the clamping member 4 enters the accommodating space 3, and the top of the clamping member 4 abuts against the expansion section 203 to support the expansion section 203. The expansion section 203 supports the sealing sleeve 101 to achieve the purpose of sealing.

[0050] Furthermore, the block 401 has a guiding inclined surface 4011 and a contact surface 4012 . After the block 401 enters the first slot 205 or the second slot 206 , the contact surface 4012 contacts the side wall of the first slot 205 or the second slot 206 .

[0051] In the utility model, in order to prevent the clamping member 4 from falling off, the clamping block 401 needs to be fixed in the first clamping slot 205 or the second clamping slot 206, and the abutting surface 4012 is perpendicular to the direction of the first clamping slot 205. When not in use, the guiding slope 4011 enters into the second clamping slot 206, and the abutting surface 4012 abuts against the second clamping slot 206. At this time, the clamping member 4 is already connected to the support member 2 and will not fall off. When sealing, the guiding slope 4011 continues to slide upward and enters the first clamping slot 205, and the abutting surface 4012 abuts against the second clamping slot 205. Similarly, at this time, the clamping member 4 is already connected to the support member 2 and will not fall off.

[0052] Furthermore, the pressing member 4 further comprises a push ring 5 , which is arranged at an end of the pressing member 4 away from the sealing member 1 .

[0053] In the present invention, in order to facilitate the pressing member 4 to enter the sealing member 1, a push ring 5 is required, and the push ring 5 is pushed by hand to make it easier for the pressing member 4 to enter the supporting member 2.

[0054] Furthermore, the diameter of one end of the inner wall of the expansion section 203 close to the push ring 5 is larger than the diameter of the other end of the inner wall.

[0055] In the utility model, in order for the seal 1 to achieve the sealing function, the diameter of the inner wall of the expansion section 203 close to the push ring 5 needs to be larger than the diameter of the other side of the inner wall. When the clamping member 4 enters the accommodating space 3, the top and the expansion section 203 abut against each other, and then the clamping member 4 will move forward to expand the expansion section 203, and the expansion section 203 will expand the positioning boss 102 to form a seal.

[0056] Furthermore, the support member 2 further includes a handle 207 . There are three handles 207 . The handle 207 is arranged at one end of the support member 2 away from the sealing member 1 . The guide plate 208 is arranged at a side of the support member 2 away from the sealing member 1 .

[0057] In the present invention, a handle 207 is provided to facilitate the pushing of the clamping member 4. One hand grasps the handle 207, and the other hand is placed on the push ring 5 to push the push ring 5 toward the sealing member 1, which makes it more convenient to push the clamping member 4. The guide plate 208 is used to guide the line.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
