Abstract
The utility model discloses a sealing rubber strip for a train inspection hole, belonging to the field of sealing devices. The sealing rubber strip comprises an installation part and a sealing part, wherein the surface of the installation part is fixed on a door frame; the sealing part comprises a bulge and a raised line, wherein the raised line and the sealing part are bifurcately arranged, the end part of the raised line is provided with a ball head with a circular section; and the ball head of the sealing part is together connected with the installation part through a support bar. According to the utility model, the support bar is arranged between the raised line and the sealing part so that the support bar can provide certain elasticity for the raised line to support the raised line to realize the sealing of the door body when the raised line is compressed by a door body, and therefore, the sealing property of the sealing rubber strip is enhanced; and in addition, the sealing rubber strip can be used for the sealing of the train inspection hole.
Description
Technical field
The utility model relates to a kind of sealing device, particularly a kind of train inspection eye sealing device.
Background technology
In recent years, the phenomenon that many city traffic block up had effectively been extenuated in city railway train fast developments such as domestic train; And through country vigorously support and make great efforts the exploitation; China's subway and track train technical level have arrived international most advanced level, and some developing countries begin to use for reference China's experience, greatly develop subway and track traffic and directly buy from China subway and track train; Simultaneously along with the Chinese Urbanization's process is accelerated day by day; More medium-sized city constantly enlarges, and its traffic is day by day severe, does not also join rail friendshipization construction ranks not shortly.Because of the market demand increases, updating and upgrading of a product rhythm is accelerated, and each track train is manufactured enterprise and born very big pressure, all on production efficiency, exploits potentialities with all strength.
In the prior art, the weather strip that is used in the train inspection eye generally comprises mounting portion 4 and hermetic unit 3, and 4 surfaces, mounting portion are fixed on doorframe 6; Hermetic unit 3 comprises a protruding 3b and a raised line 3a; Raised line 3a and hermetic unit 3 bifurcateds are arranged, and the end of raised line 3a is provided with the rounded bulb 3c in cross section, when needs are closed inspection eye; The raised line 3a of hermetic unit 3 seals as first road; Protruding 3b seals the sealing that has realized inspection eye as second road, because inspection eye needs to switch under the on off state through being everlasting, the hermetic unit 4 and the mounting portion 3 of bifurcation structure just make raised line 3a lose enough elasticity; The serious raised line root that is provided with ftractures, thereby can't accomplish the sealing to inspection eye.
The utility model content
The purpose of the utility model provides a kind of train inspection eye sealing joint strip, has strengthened its sealing performance, has prolonged the application life of weather strip.
The purpose of the utility model is achieved in that a kind of train inspection eye sealing joint strip; Comprise mounting portion and hermetic unit; Surface, said mounting portion is fixed on the doorframe, and said hermetic unit comprises a convexity and a raised line, and said raised line and hermetic unit bifurcated are arranged; The end of said raised line is provided with the rounded bulb in cross section, links together through support bar between the bulb of said hermetic unit and the mounting portion.
In the utility model work, when needs were closed inspection eye, the raised line of hermetic unit sealed as first road; Convexity seals the sealing that has realized inspection eye as second road; Compared with prior art, the beneficial effect of the utility model is that the utility model is through being provided with support bar between raised line and hermetic unit; Make raised line the time by the compression of door body; Support bar can provide certain resilient support raised line to realize the sealing of opposite house body to raised line, thereby has strengthened the sealing performance of weather strip, and has prolonged the application life of weather strip.The utility model can be used in the sealing to the train inspection eye.
In order to make that support bar can be outwardly-bent smoothly when being compressed, said support bar is respectively arranged with chamfering with the two ends that bulb, support bar are connected with the mounting portion.
In order to make weather strip easy for installation, said mounting portion through adhesive tape bonding on doorframe.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 body, 2 support bars, the 2a chamfering, 3 hermetic units, the 3a raised line, 3b is protruding, 3c bulb, 4 mounting portions, 5 adhesive tapes, 6 doorframes.
The specific embodiment
A kind of train inspection eye sealing joint strip as shown in Figure 1; Comprise mounting portion 4 and hermetic unit 3; 4 surfaces, mounting portion are bonded on the doorframe 6 through adhesive tape 5; Hermetic unit 3 comprises a protruding 3b and a raised line 3a, and raised line 3a and hermetic unit 3 bifurcateds are arranged, and the end of raised line 3a is provided with the rounded bulb 3c in cross section; Link together through support bar 2 between the bulb 3c of hermetic unit 3 and the mounting portion 4, support bar 2 is respectively arranged with chamfering 2a with the two ends that bulb 3c, support bar 2 are connected with mounting portion 4.
In the utility model work; Through between raised line 3a and hermetic unit 3, support bar 2 being set; When making raised line 3a again by 1 compression of door body; Support bar 2 provides certain resilient support raised line 3a to realize the sealing of opposite house body 1 can for raised line 3a, thereby has improved the sealing performance of weather strip, and has prolonged the application life of weather strip.
The utility model is not limited to the foregoing description; On the basis of the disclosed technical scheme of the utility model; Those skilled in the art is according to disclosed technology contents; Do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in the protection domain of the utility model.
