Abstract
The utility model discloses a telescopic device with strong anti-pressure capacity. The telescopic device with the strong anti-pressure capacity comprises a rubber tube, wherein two ends of the rubber tube are respectively and fixedly connected with a connection flange in a sealing mode. The connection flanges are respectively connected with a plurality of guide rods, and every two guide rods penetrate through each other and are connected in a sliding mode. In the every two guide rods which penetrate through each other, a spring is sleeved outside an inner side guide rod, and the spring stretches into an outer side guide rod. Each spring contacts with the connection flanges at the two ends of the rubber tube in an elastic mode, and a strengthening rib is arranged between each outer side guide rod and each connection flange. According to the telescopic device with the strong anti-pressure capacity, the strengthening rib is additionally arranged between each guide rod and each connection flange, and therefore the service life of the telescopic device is prevented from being affected due to the fact that guide rods crack in the process of usage. The telescopic device with the strong anti-pressure capacity is good in pressure resistance and elasticity, capable of absorbing vibration and lowering noise and convenient to install.
Description
Technical field
The utility model relates to pipeline connector spare, relates in particular to a kind of expansion bend of pressure resistance.
Background technique
Expansion bend can be called vibration damper, soft connector etc. again, is the flexible connector of metallic conduit, is comprised of telescopic body, metal flange, if should not connect apparatus, can increase the possibility that metallic conduit damages, and increases user cost.Expansion bend design of the prior art is unreasonable, and is fragile a little less than causing anti-pressure ability, easily breaks, and working life is short.
The model utility content
The utility model purpose is exactly in order to make up the defective of prior art, a kind of expansion bend of pressure resistance to be provided.
The utility model is achieved through the following technical solutions:
A kind of expansion bend of pressure resistance, comprise rubber pipe, the described rubber tube terminal adpting flange that all has been sealedly and fixedly connected, all be connected with a plurality of guide rods on described adpting flange, and every two guide rods run through mutually and are slidably connected, among every two guide rods that mutually run through, inboard guide rod outside cover has spring, and it is inner that spring extend into outside guide rod, and described spring and two ends adpting flange Elastic Contact are provided with stiffening rib between described outside guide rod and adpting flange.
Described adpting flange side is provided with circular groove, is bonded with complete diaphragm seal on the side He in circular groove.
The utility model has the advantages that: the utility model is by increasing stiffening rib between guide rod and adpting flange, prevent in use fracture of guide rod, affect the working life of expansion bend, but withstand voltage good, good springiness absorbing moving, reduce noise, easy for installation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of expansion bend of pressure resistance, comprise rubber pipe 1, the described rubber pipe 1 two ends adpting flange 2 that all has been sealedly and fixedly connected, all be connected with a plurality of guide rods 3 on described adpting flange 2, and every two guide rods 3 run through mutually and are slidably connected, among every two guide rods that mutually run through 3, inboard guide rod outside cover has spring 4, and it is inner that spring 4 extend into outside guide rod, described spring 4 and two ends adpting flange 2 Elastic Contact are provided with stiffening rib 6 between described outside guide rod and adpting flange 2.
Described adpting flange 2 sides are provided with circular groove 5, are bonded with complete diaphragm seal on the side He in circular groove 5.
Claims (2)
1. the expansion bend of a pressure resistance, comprise rubber pipe, it is characterized in that: the described rubber tube terminal adpting flange that all has been sealedly and fixedly connected, all be connected with a plurality of guide rods on described adpting flange, and every two guide rods run through mutually and are slidably connected, among every two guide rods that mutually run through, inboard guide rod outside cover has spring, and it is inner that spring extend into outside guide rod, and described spring and two ends adpting flange Elastic Contact are provided with stiffening rib between described outside guide rod and adpting flange.
2. the expansion bend of pressure resistance according to claim 1 is characterized in that: described adpting flange side is provided with circular groove, is bonded with complete diaphragm seal on the side He in circular groove.
