The lower end of upper piston rod is fixedly connected with lower piston rod, the diameter of lower piston rod is less than the internal diameter of described lower piston sleeve, the coaxial of lower piston rod and described lower piston sleeve is arranged, lower piston rod is provided with lower seal ring recess, lower seal ring recess is near the lower end of described lower piston rod, and the lower end of lower seal ring recess exists certain distance to the lower end of lower piston rod, described lower seal ring recess is combined with described O RunddichtringO.
Further, described upper piston rod is provided with locating slot, ringwise, locating slot is provided with chute to locating slot on the lower end of described upper piston rod, described upper piston rod, chute is parallel to the axially arranged of described upper piston rod, chute connects with locating slot in lower end, and the side of described upper piston sleeve is provided with hole, location, and hole, location is near the upper end of upper piston sleeve, hole, location connects described upper piston sleeve, and there is pilot pin location by threaded engagement in hole.
Further, the lower end of described lower piston rod is fixedly connected with transition face, and transition face is with any one cross curve through the cross section of lower piston rod axis arcuately.
Further, described installing plate is equilateral triangle in uniform thickness, described sucker is connected to the geometric center place of installing plate, and described connecting tube is connected to one of them drift angle place of installing plate, and two other top board place of installing plate is respectively connected to a support bar by screw thread.
Further, the bottom of described each support bar has been respectively fixedly connected with cushion pad.
The invention has the beneficial effects as follows:
1, a kind of windshield obturator provided by the invention, staff is when using the present invention that the crackle on windshield is repaired, the opening of connecting tube lower end is placed on the slit region of windshield, then uses sucker to be adsorbed on the windshield of automobile by installing plate.Then checking air inlet switch, it is ensured that air inlet is in the state of closing, then the upper end of hand-held upper piston rod accelerates to pull up upper piston rod.We are region E being positioned at upper piston sleeve and be positioned at the portion markings of below upper piston rod lower end, and in the process pulling up upper piston rod, the air in the E of region expands gradually, so the air pressure in D region tapers into.Again because the external diameter of upper piston rod is less than the internal diameter of upper piston sleeve, so there is certain space between upper piston rod and upper piston sleeve, again because of the opening up setting of V-type, so V-type opening connects with ambient atmosphere, so when pulling up upper piston rod, the air pressure at the bottom more than V-shaped seal ring 51 of the air pressure in V-type opening 52 and outer circumferential position place, the outer circumference of such V-shaped seal ring be compressed on the inwall of upper piston sleeve thus and define sealing between upper piston sleeve, so just can by whole for the air in glass gap sucking-offs in the process of pull-up upper piston rod, thus completing the work of evacuation.
After using the present invention to complete the work of evacuation, opening air inlet switch makes air inlet connect with outside air, then pass through and the inner chamber of air inlet up piston sleeve injects a certain amount of glue, under gravity is made, glue is flowed into lower piston sleeve from upper piston sleeve, then air inlet switch 33 is used to close air inlet, then at the uniform velocity promoting the upper end of upper piston rod that upper piston rod is moved downward, lower piston rod synchronizes to move downward with upper piston rod.In the process that upper piston rod at the uniform velocity moves downward, the deformation that V-shaped seal ring will not expand outwardly, so the outer ring of V-shaped seal ring does not compress with the inwall of upper piston sleeve, so the outer ring of V-shaped seal ring is in unsealed state all the time with the inwall of upper piston sleeve in this process, that is in the process that upper piston rod at the uniform velocity moves downward, air beyond region E and piston apparatus is in the isobaric state being interconnected, and so when O RunddichtringO does not also coordinate with lower piston sleeve, glue will not be gone by note extrusion.
Lower piston rod continues in the process moved downward, lower piston rod is positioned at part elder generation and the glue-contact of below O RunddichtringO, owing to the external diameter of lower piston rod is less than the internal diameter of lower piston sleeve, so if located in the volume of the glue in the inner chamber of lower piston sleeve less than the words of the volume of lower piston sleeve, lower piston rod is arranged in after the part of below O RunddichtringO just can will be located in the air extrusion of lower piston sleeve discharges, lower piston rod continues to move downward, formed between outer ring and the inner ring of lower piston sleeve of O RunddichtringO and seal, thus glue 6 note being pressed onto in the gap needing to repair.
So, the present invention both can ensure that complete for the air in windshield gap sucking-off, it is ensured that being smoothed out of evacuation work, can avoid again being pressed onto in the gap of windshield air note, it is to avoid windshield is caused secondary damage in injecting glue process.
2, after evacuation end-of-job, there is negative pressure in upper piston sleeve, staff to ensure that the lower end of upper piston rod is near the upper end of upper piston sleeve before by air inlet open.Regulate upper piston rod then rotational positioning bolt so that one end of pilot pin coordinates with locating slot, and such piston rod is just relatively fixed in the axial direction.The process using the present invention makes the lower end of pilot pin coordinate with chute all the time, upper piston rod so can be avoided to come off from upper piston sleeve.
3, the transition face of arch can improve the ability of lower piston sleeve aerofluxus, thus avoiding air to be pressed onto in the gap of windshield by note further.
4, the mounting means of the isosceles triangular structure of installing plate, the installation site of sucker, the setting of support bar and support bar, advantageously ensure that installing plate is relatively fixed on the windshield smoothly, thus avoiding the opening of the lower end of connecting tube to depart from from the slit region of windshield, thus ensureing evacuation and the quality of injecting glue work.
5, cushion pad can play the effect preventing windshield to be scratched.
