Abstract
The utility model discloses a gas meter connector, which consists of a tube body (1) and rivet flanges (2), wherein the rivet flanges (2) are arranged at tail ends of the tube body (1), and spline riveting teeth (3) are uniformly distributed on the rivet flanges (2). The riveting teeth are disposed on the rivet flanges of the gas meter connector, thereby increasing riveting strength of the rivet flanges and a gas meter casing, being capable of guaranteeing stable connection between the gas meter connector and a gas meter, increasing torsional strength of the gas meter connector, and improving sealing effect of the gas meter connector. In addition, the gas meter connector has the advantages of simple and convenient installation, high strength, fine safety and the like.
Description
Technical field
The utility model relates to a kind of link that is used for gas meter, flow meter, specifically, is a kind of gas meter, flow meter joint.
Background technology
The joint of use in gas ductwork needs also to prevent that combustion gas from revealing and security incident takes place except needs guarantee that combustion gas can smooth and easy circulation, the sealing effectiveness of butt junction has very high requirement.Present gas meter, flow meter joint adopts the form of flange riveted joint usually, turning over of joint is carried out the rolling punching press after the riveting limit extend into the gas meter, flow meter enclosure interior, thereby the joint flange is riveted on the vent locations of gas meter, flow meter.But still there are problems such as installation is firm inadequately, twisting strength is limited in this class flange riveted joint type joint, and security performance waits further raising.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model provides the high gas meter, flow meter joint of a kind of installation strength.
For this reason, concrete scheme of the present utility model is: a kind of gas meter, flow meter joint, form by the body and the riveting limit of turning over that is arranged at the body end, and turn over the riveting limit and be provided with the equally distributed spline type tooth that presses.The tooth that presses can increase the tightness of turning over riveting limit clamping gas meter, flow meter housing.
According to an aspect of the present utility model, turn over and equally spaced be provided with six spline types tooth that presses on the riveting limit.Equally spaced be provided with the tooth that presses can guarantee to turn over the riveting limit on all directions stressed evenly, avoid dislocation being installed because of unbalance stress produces.
According to an aspect of the present utility model, body top and turn between the riveting limit and be provided with stiffening plate, the below of stiffening plate also is provided with " O " RunddichtringO.Stiffening plate can increase the clamping tightness of turning over the riveting limit, and O-ring seal is made by resilient material, can sealing adaptor and the fine gap of gas meter, flow meter junction, thus improve the sealing property of joint effectively.
Compared with prior art, the beneficial effects of the utility model are: this gas meter, flow meter joint is provided with the tooth that presses and increases the riveting intensity that turns over riveting limit and gas meter, flow meter shell turning on the riveting limit, can guarantee that joint is connected with the firm of gas meter, flow meter, improve the twisting strength of gas meter, flow meter joint, and the sealing effectiveness of raising gas meter, flow meter joint, have advantages such as simple installation, intensity height and security performance are good.
Description of drawings
Above-mentioned and/or additional aspect of the utility model and advantage are from obviously and easily understanding becoming the description of embodiment below in conjunction with accompanying drawing, wherein:
Fig. 1 is the structural representation of gas meter, flow meter joint of the present utility model;
Fig. 2 is the side view of Fig. 1.
Embodiment
Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar device or the device with identical or similar functions.Below by the embodiment that is described with reference to the drawings is exemplary, only is used to explain the utility model, and can not be interpreted as restriction of the present utility model.In description of the present utility model, term " on ", position such as D score relation is for based on position shown in the drawings relation, it only is the utility model rather than require the utility model therefore can not be interpreted as for convenience of description with specific orientation structure and operation to restriction of the present utility model.
Shown in Fig. 1 and Fig. 2 is the structure of gas meter, flow meter joint of the present utility model.This gas meter, flow meter joint is made up of the body 1 and the riveting limit 2 of turning over that is arranged at body 1 end, and turns over riveting limit 2 and is provided with the equally distributed spline type tooth 3 that presses.Body 1 normally cross sectional shape is circular metal tube, turns over riveting limit 2 and is the circumference metal edges identical with body 1 shape, extend into the gas meter, flow meter enclosure interior and carries out the roll riveting processing and just can realize turning over combining of riveting limit 2 and gas meter, flow meter after the backfin bending turning over riveting limit 2.Outside the turning on the riveting limit 2 tooth 3 that presses can also be set of turnover, carry out pressing according to the position of the tooth 3 that presses and further to increase the tightness of turning over riveting limit 2 clamping gas meter, flow meter housings.
From Fig. 1, it can also be seen that, turn over and equally spaced be provided with six spline types tooth 3 that presses on the riveting limit 2.Equally spaced be provided with circumference that the tooth 3 that presses can guarantee to turn over riveting limit 2 on all directions stressed evenly, avoid dislocation being installed because of unbalance stress produces.Certainly, tooth 3 numbers are many more if press, the installation strength that is increased is just strong more, but incident is that difficulty of processing also can correspondingly increase, the number of tooth 3 can be selected flexibly according to manufacturing materials and installation requirement so spline type presses, and just can play the effect of steady connection, increase installation strength as long as the tooth 3 that presses evenly distributes on the circumference that turns over riveting limit 2.
At body 1 top of gas meter, flow meter joint and turn between the riveting limit 2 and can also be provided with stiffening plate 5, the below of stiffening plate 5 also is provided with " O " RunddichtringO 4.Stiffening plate 5 is used to increase the tightness of turning over riveting limit 2 turnover back clamping gas meter, flow meter shells, O-ring seal 4 generally can be made by the rubber elastomeric material, be used for the flexibly fine gap of sealing adaptor and gas meter, flow meter junction, can improve the sealing property of joint effectively.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
