Detailed Description
The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.
example 1
A hot melt pipe cap, refer to fig. 1-5, including the hot melt pipe cap body 1 made of PE material, the inside of hot melt pipe cap body 1 is provided with the internal thread that cooperates with pipeline external screw thread, there is a cavity 101 near opening week department sunken in the inner wall of hot melt pipe cap body 1, an annular gasbag 2 has been put in the cavity 101, annular gasbag 2 is made annular gas by rubber, the one end that the gasbag is close to the bottom of cavity 101 sets up with cavity 101 adhesion, there is a through-hole that feeds through the outer wall of hot melt pipe cap body 1 in the sunken through-hole that is provided with of cavity 101 bottom, be provided with the inflation hose 3 that leads to annular gasbag 2 on the annular gasbag 2, this inflation hose 3 is made by rubber, the top of inflation hose 3 is connected with the charging plug 4 with the charging connector complex of air pump, the charging plug 4 is prior art, generally use on.
A first groove 102 which is communicated with the through hole and can contain the turned inflation hose 3 and the turned inflation plug 4 is concavely arranged on the outer wall of the hot melting pipe cap body 1, and a blocking mechanism which limits the inflation hose 3 to pop out of the first groove 102 is arranged in the first groove 102.
Stop mechanism includes and keeps away from the second recess 104 that the opening one end inner wall is sunken on the first recess 102 and is the same width with first recess 102, the flexible baffle 7 that is provided with in second recess 104, the both sides inner wall of second recess 104 is provided with the guide way 103 that extends to first recess 102 inner wall along baffle 7 traffic direction, be provided with in the both sides of baffle 7 with guide way 103 complex slider that slides, still be provided with stop gear between slider and guide way 103, this stop gear includes and is close to the protruding most advanced outside card 6 of establishing of opening one end in the slider, be provided with the draw-in groove 1031 with the protruding 6 block of card near open-ended one end at guide way 103.
one end of the upper end surface of the baffle 7 close to the opening is vertically and fixedly arranged or is provided with a shifting block 5 which is convenient for shifting the baffle 7 back and forth in a pivoted mode.
When the hot-melting pipe cap of the scheme is used for connecting a pipeline, no air exists in the annular air bag 2 at first, the air bag is adsorbed at the bottom of the cavity 101, the inflating plug 4 is inflated by an inflator or an air pump after the hot-melting pipe cap is screwed with the pipeline, the annular air bag 2 is inflated and then is expanded, and only the annular air bag abuts against the outer wall of the pipeline to play a sealing role, when the hot-melting pipe cap needs to be detached, the inflating plug 4 is deflated firstly, and then the hot-melting pipe cap is screwed down from the pipeline; after the inflation is finished, in order to avoid the protruding inflation plug 4 from being pressed, the inflation hose 3 is turned over and then accommodated in the first groove 102 together with the inflation plug 4, and then the shifting block 5 is grasped to draw the baffle plate 7 out of the second groove 104 until the clamping protrusion 6 is matched with the clamping groove 1031, so that the inflation plug 4 can be prevented from being accidentally touched to cause the leakage of the gas in the annular airbag 2.
Example 2
The difference between this embodiment and embodiment 1 is that, referring to fig. 6-8, a return spring 8 is disposed between the bottom of the second groove 104 and an end of the baffle 7 away from the first groove 102, when the return spring 8 extends, the baffle 7 extends out of the second groove 104 to block the inflation plug 4, and when the return spring 8 contracts, the baffle 7 retracts into the second groove 104, and at this time, the inflation plug 4 automatically bounces and resets.
This scheme need not to set up protruding 6 of card and draw-in groove 1031, because reset spring 8 is in the state of extending under the normal condition, so when not being to baffle 7 application of force, baffle 7 is in the state of stretching out naturally, and inflation plug 4 has bounce-back reset force, and this power is opposite with the flexible power of reset spring 8, so inflation plug 4 can't reset when baffle 7 stretches out and is accomodate in first recess 102.
Naturally, the above is only the typical example of the present invention, in addition, the present invention can also have other multiple specific embodiments, and all the technical solutions formed by adopting equivalent replacement or equivalent transformation all fall within the scope of the present invention.
