Abstract
The utility model discloses a durable expansion device which comprises rubber hoses. Two ends of each rubber hose are respectively fixedly connected with a connecting flange in a sealed mode. A plurality of guide rods are connected on each connecting flange. Every two guide rods penetrate each other and are in sliding connection. In every two guide rods which penetrate each other, a spring is sleeved on an outer side of an inner side guide rod, and the spring stretches into the interior of an outer side guide rod, the spring is in elastic contact with the connecting flanges at the two ends of the corresponding rubber hose, a reinforcing rib is arranged between the outer side guide rod and the corresponding connecting flange, and annular rubber layers are arranged on end portions of the guide rods. Due to the fact that the annular rubber layers are arranged on the end portions of the guide rods, when the springs are compressed, the impact force of the guide rods and the opposite flanges is reduced, the guide rods are prevented from being fractured, the service life of the expansion device is prolonged, and the durable expansion device is good in pressure-resisting performance and elasticity, capable of absorbing vibration and reducing noise, and convenient to install.
Description
Technical field
The utility model relates to the interface unit of pipeline, relates in particular to a kind of durable expansion bend.
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 durable expansion bend to be provided.
The utility model is achieved through the following technical solutions:
A kind of durable expansion bend, 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, described spring and two ends adpting flange Elastic Contact, be provided with stiffening rib between described outside guide rod and adpting flange, the end of described guide rod is equipped with the ring-shaped rubber layer.
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 established the ring-shaped rubber layer in the end of guide rod, when spring is compressed, reduced the impact force of guide rod and opposite adpting flange, prevent the guide rod fracture, extend the working life of expansion bend, but withstand voltage good, the 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 durable expansion bend, 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, and the end of described guide rod 3 is equipped with ring-shaped rubber layer 7.
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.
