Description

Technical Field

[0001] The utility model relates to the technical field of sealing devices, in particular to a rubber seal for a metal bracket. Background Art

[0002] Tubular metal brackets have high strength and stiffness. Due to the high strength and stiffness of the metal material itself, as well as welding or bolt connection methods, tubular metal brackets can support relatively large weights and forces. Since metal tubular brackets can be spliced and assembled through different connection methods (such as threading, welding, etc.), they are relatively easy to transport and install.

[0003] For some special tubular metal brackets, sealing is required during installation, which requires the use of rubber seals. However, existing rubber seals have problems such as inconvenient installation, complex operation, and narrow application range.

[0004] After retrieval, the Chinese utility model patent with the authorization announcement number CN 219140105 U discloses a pipeline rubber seal, including a seal body. Connecting chambers are symmetrically arranged on the left and right sides of the seal body. A locking and sealing mechanism is arranged on the outer side of the connecting chamber. A pipeline body is slidably clamped inside the connecting chamber. Connecting grooves with a trapezoidal cross-section structure are symmetrically arranged on the outer surface of the seal body. A reinforcement mechanism is arranged inside the connecting groove. In the utility model, by setting connecting threads, it can be connected with the pipeline body. The stepped convex blocks cooperate with the connecting member body to position the pipeline body. The locking member body 1 and the locking member body 2 cooperate to be clamped inside the connecting groove, and then the seal body can be locked. The position of the positioning member body can be adjusted by adjusting the screw rod, and the positioning ring body and the locking clamp can be locked, and the locking member body 1 and the locking member body 2 can be adjusted and locked according to the degree of looseness of the seal.

[0005] However, the above device has at least the following technical defects

[0006] 1. The locking member is sleeved on the outer side of the seal body and locked by a locking clamp. The locking clamp has a complex structure and inconvenient operation, and requires a relatively large operating space during operation, which is not conducive to installation in places with a small operating space. Therefore, there is a technical defect of a small application range.

[0007] 2. In the above device, sealing is carried out through the seal body. The seal body and the pipeline body are connected by an insertion method. At the insertion part, leakage of transported substances is likely to occur, resulting in a technical defect of poor sealing effect. The connecting grooves arranged on the seal body reduce the thickness of the seal itself, and the use of tightening members further reduces the service life of the seal body.

[0008] In summary, there are still many technical defects in the above device, so it needs to be improved. Utility Model Content

A second clamping groove 202 is opened at the top of the second protruding platform 201, and an annular protruding block adapted to the sealing groove 401 is integrally formed at the bottom of the second protruding platform 201.

[0032] An annular boss is opened on the inner wall of the bracket tube of the first connecting member 1, and the bottom of the bracket tube of the second connecting member 2 is in contact with the upper surface of the annular boss.

[0033] An installation groove is opened on the inner wall of the first connecting member 1, and an annular sealing gasket 6 is installed on the inner wall of the installation groove. The inner edge of the annular seal is deformed by the extrusion of the bracket tube of the second connecting member 2.

[0034] At least two installation grooves are opened on the outer surface of the bracket tube of the second connecting member 2, and an annular rectangular sealing gasket 5 with a rectangular cross-section is installed on the inner wall of the installation groove. The rectangular sealing gasket 5 is deformed by the extrusion of the inner wall of the bracket tube of the first connecting member 1.

[0035] The locking assembly includes a locking frame 301. A bolt 303 is rotatably connected to the bottom end of the locking frame 301. The bolt 303 penetrates through the top of the locking frame 301. A stop block is fixedly connected to the top of the bolt 303. Two limiting grooves 302 are formed in the inner wall of the locking frame 301 on the side away from the first connecting member 1. A movable member 304 that can move up and down is threadedly connected to the outer surface of the bolt 303.
