Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sealing gasket, specifically to a rubber sealing gasket convenient to install. BACKGROUND

[0002] The sealing gasket is an elastic functional element for filling the gap between mechanical or structural connecting parts and preventing fluid / gas leakage, and its core principle is to realize sealing by deformation compensation and interface fitting.

[0003] The Chinese patent with publication number CN221300104U discloses a rubber sealing gasket convenient to install, which is provided with an installation assembly. When the surface of the rubber sealing gasket abuts against the side slope of the card plate away from the bottom disc, the card plate moves away from the side of the metal outer circle, thereby driving the connecting rod to move the rod synchronously, and at the same time, the rubber rod is stretched. When the position of the card plate is parallel to the card slot, the rubber rod returns, thereby driving the connecting rod to return to the original position, and the connecting rod drives the card plate to enter the card slot, so that the card plate limits the card slot. At this time, the rubber sealing gasket is stable with the metal outer circle, and it is convenient to install.

[0004] In the above-mentioned patent, since the diameter of the rubber sealing gasket is larger than the diameter of the through hole, the rubber sealing gasket will deform to a certain extent when it enters the through hole, thereby affecting the size of the card slot. In addition, the rubber sealing gasket lacks positioning when it enters the through hole, and it is difficult to ensure that the card slot and the card plate are accurately corresponding, so it is difficult for the card plate to accurately insert into the card slot, resulting in the inconvenience of installation. In addition, the above-mentioned patent removes the rubber sealing gasket by rotating it. Since the surface of the rubber sealing gasket is smooth and flat, and has a certain friction with the inner wall of the through hole, it is difficult to rotate manually, and other tools are needed, thereby increasing the complexity of replacing the rubber sealing gasket.

[0025] The technical scheme in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] Please refer to Figures 1-5 The utility model provides a kind of rubber sealing gasket of convenient installation, including metal outer ring 100 and rubber sealing gasket 101, four mounting seats 103 are installed to the outer surface annular array of metal outer ring 100, and the upper surface of mounting seat 103 is flush with the upper surface of metal outer ring 100, arc clamping plate 104 is slidably installed on the upper surface of mounting seat 103 along its length direction, arc clamping plate 104 is provided with arc clamping plate 105 on inner side, and annular clamping groove 102 is set on the outer surface of rubber sealing gasket 101.Arc clamping plate 104 and mounting seat 103 are provided with fixing mechanism 200, and fixing mechanism 200 can fix arc clamping plate 104.

[0027] In use, first slide the four arc-shaped clamping plates 104 to the side away from the center of the metal outer ring 100, at this time the four arc-shaped clamping plates 104 are separated from each other, the rubber sealing gasket 101 can be directly placed into the through hole of the metal outer ring 100, then slide the arc-shaped clamping plates 104 to the center of the metal outer ring 100, when they slide to the end position, use the fixing mechanism 200 to fix them, when the four arc-shaped clamping plates 104 form a complete annular structure and are fixed, the four arc-shaped clamping plates 105 are inserted into the annular clamping groove 102, thereby completing the quick installation of the rubber sealing gasket 101, without considering the angle of the rubber sealing gasket 101 during installation, and the contact area between the arc-shaped clamping plate 105 and the annular clamping groove 102 is larger, and the positioning effect is better.

[0028] Similarly, by sliding the arc-shaped clamping plate 104 to separate it from the surface of the rubber sealing gasket 101 and driving the arc-shaped clamping plate 105 out of the annular clamping groove 102, the rubber sealing gasket 101 can be directly pulled out of the through hole of the metal outer ring 100, thereby improving the replacement efficiency of the rubber sealing gasket 101 and making the use more convenient.

[0029] Preferably, the fixing mechanism 200 comprises a fixing sleeve 201 mounted on the outer surface of the arc-shaped clamping plate 104, a plug rod 202 inserted in the inside of the fixing sleeve 201, and a plug hole 203 opened on the upper surface of the mounting seat 103 and matched with the plug rod 202. An shaft shoulder 204 is arranged on the outer surface of the plug rod 202 and below the fixing sleeve 201, and an elastic member 205 is arranged on the outer surface of the plug rod 202 and between the shaft shoulder 204 and the fixing sleeve 201.

[0030] When the arc-shaped clamping plate 104 slides to the end closest to the center of the metal outer ring 100, the plug rod 202 is just above the plug hole 203, at this time the plug rod 202 is inserted into the plug hole 203, thereby fixing the position of the arc-shaped clamping plate 104, and under the action of the elastic member 205, the plug rod 202 can be stably inserted into the plug hole 203, avoiding the safety hazard of disengagement during use. When the plug rod 202 is pulled out of the plug hole 203, the fixation of the arc-shaped clamping plate 104 is released, so that it can slide away from the center of the metal outer ring 100.

[0031] Preferably, a T-shaped sliding groove 300 is opened on the upper surface of the mounting seat 103 along the length direction thereof, and a T-shaped sliding block 301 is slidably installed in the inside of the T-shaped sliding groove 300, and the top of the T-shaped sliding block 301 is connected with the lower surface of the arc-shaped clamping plate 104.

[0032] The arrangement of the T-shaped sliding groove 300 and the T-shaped sliding block 301 enables the arc-shaped clamping plate 104 to have the ability of horizontal sliding, and the T-shaped sliding groove 300 and the T-shaped sliding block 301 have a limiting effect, which can avoid the separation of the arc-shaped clamping plate 104 from the mounting seat 103.

[0033] Preferably, the outer surface of the arc-shaped clamping plate 104 is provided with two sets of fixing mechanisms 200, and the two sets of fixing mechanisms 200 are symmetrically distributed on both sides of the width direction of the T-shaped sliding groove 300, and the top of the two insertion rods 202 is jointly provided with a connecting rod 400.

[0034] Because the arc-shaped clamping plate 104 exerts a certain extrusion force on the rubber sealing gasket 101, the arc-shaped clamping plate 104 is continuously subjected to the thrust of the rubber sealing gasket 101 during use, and therefore the setting of the two sets of fixing mechanisms 200 can further enhance the supporting effect on the arc-shaped clamping plate 104, and guarantee the integrity of the overall structure, and the setting of the connecting rod 400 can simultaneously drive the two insertion rods 202 to rise and release the fixation of the arc-shaped clamping plate 104.

[0035] Preferably, the elastic member 205 is a spring.

[0036] The spring exerts a downward thrust on the shaft shoulder 204, so that the insertion rod 202 can be stably inserted into the insertion hole 203.

[0037] The elastic member 205 can also be provided as a rubber sleeve or a silica gel sleeve, because it has a certain deformation ability, when the insertion rod 202 is pulled upward, the shaft shoulder 204 exerts an upward thrust on the rubber sleeve or the silica gel sleeve, so that it is deformed and shrinks, so that the insertion rod 202 can be pulled out of the insertion hole 203.

[0038] Preferably, the upper and lower sides of the end of the arc-shaped clamping plate 105 are both inclined surface structures.

[0039] By setting both sides of the end of the arc-shaped clamping plate 105 as inclined surface structures, when the four arc-shaped clamping plates 104 are combined into a complete annular structure, the inner wall thereof will exert a certain extrusion force on the rubber sealing gasket 101, which may cause the annular clamping groove 102 to deform, and therefore the inclined surface structure of the end of the arc-shaped clamping plate 105 can be inserted into the annular clamping groove 102 and expand it, so that the subsequent part of the arc-shaped clamping plate 105 can smoothly enter the annular clamping groove 102.

[0040] The standard parts used in the utility model can be purchased from the market, the special-shaped parts can be ordered according to the description and the drawings, the specific connection mode of each part adopts the conventional means such as bolts, rivets and welding in the existing technology, the machinery, parts and equipment adopt the conventional types in the existing technology, and the circuit connection adopts the conventional connection mode in the existing technology, which will not be described in detail here, and the contents not described in detail in the description belong to the existing technology known to the person skilled in the art.

[0041] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
