The technical scheme of a kind of vacuum suction cup assembly of this utility model it may also is that
The top of described fixed cover is provided with the top of shoulder, the bottom of described shoulder and described fixing port and offsets.
The bottom of described fixed cover is provided with the groove that at least two is upwards offered.
Described groove is arranged along the diametric(al) of described fixed cover.
The profile of described groove is rectangle.
The bottom of described fixed cover is provided with steam vent.
Described steam vent is evenly distributed on the bottom of described fixed cover.
The inwall interference fit of the outer ring of described fixed cover and described fixing port.
A kind of vacuum suction cup assembly of the present utility model, including tank body, piston and fixed cover, the top of described tank body stretches out and is provided with fixing port, described fixing port connects the inside of described tank body with outside, described piston is plugged in described fixing port, the inner ring of described fixed cover is set on described piston, and the inwall of the outer ring of described fixed cover and described fixing port offsets, and the top of the top of described fixed cover and described fixing port offsets. So, first inserting the piston in fixing port, then by fixed cover through piston, and inserted by fixed cover in fixing port so that the outer ring of fixed cover and fixing port inwall offset, vacuum suction cup modular construction of the present utility model is simple, and easy for installation.Thus, piston is served auxiliary and supports and the effect of protection by fixed cover, and the setting of fixed cover decreases piston and the mount stress of tank body splicing position, and then and reduce the fracture phenomena of tank body, improve yield rate.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, a kind of vacuum suction cup assembly of the present utility model is further described.
As Figure 1-4, a kind of vacuum suction cup assembly, including tank body 3, piston 2 and fixed cover 1, the top of described tank body 3 stretches out and is provided with fixing port 4, described fixing port 4 connects the inside of described tank body 3 with outside, and described piston 2 is plugged in described fixing port 4, and the inner ring of described fixed cover 1 is set on described piston 2, the inwall of the outer ring of described fixed cover 1 and described fixing port 4 offsets, and the top of the top of described fixed cover 1 and described fixing port 4 offsets. So, first piston 2 is inserted in fixing port 4, then by fixed cover 1 traverse piston 2, and fixed cover 1 is inserted in fixing port 4, the outer ring making fixed cover 1 offsets with fixing port 4 inwall, and vacuum suction cup modular construction of the present utility model is simple, and easy for installation. Thus, piston 2 is served auxiliary and supports and the effect of protection by fixed cover 1, and the setting of fixed cover 1 decreases piston 2 and the mount stress of tank body 3 splicing position, and then and reduce the fracture phenomena of tank body 3, improve yield rate.
Referring to accompanying drawing 1-4, a kind of vacuum suction cup assembly of the present utility model is on the basis of technique scheme, it is possible to be: the top of described fixed cover 1 is provided with the top of shoulder 5, the bottom of described shoulder 5 and described fixing port 4 and offsets. As such, it is possible to hold shoulder 5 to insert or extract fixed cover 1, it is simple to the installation to fixed cover 1.
Referring to accompanying drawing 1-4, a kind of vacuum suction cup assembly of the present utility model is on the basis of technique scheme, it is possible to be: the bottom of described fixed cover 1 is provided with the groove 6 that at least two is upwards offered. So, fixed cover 1 part being positioned at groove 6 both sides when inserting fixed cover 1 can be polymerized to groove 6, and then decreases the diameter of fixed cover 1, so that fixed cover 1 is inserted in fixing port 4. After fixed cover 1 is fully-inserted, fixed cover 1 part of groove 6 both sides can be opened outside groove 6, so that the outer ring of fixed cover 1 can closely offset with fixing port 4 inwall. It is preferred that technical scheme may is that described groove 6 is arranged along the diametric(al) of described fixed cover 1. So, the groove 6 arranged along the diametric(al) of fixed cover 1, it is possible in the process inserting fixed cover 1 so that fixed cover 1 reduces diameter to groove 6 direction, consequently facilitating the insertion of fixed cover 1. It is preferred that technical scheme may is that the profile of described groove 6 is rectangle. As such, it is possible to reduce space for what fixed cover 1 had reserved diameter on the width of groove 6. The profile of certain groove 6 is not limited to rectangle, and the profile of groove 6 can also be U-shaped.
Referring to accompanying drawing 1-4, a kind of vacuum suction cup assembly of the present utility model is on the basis of technique scheme, it is possible to be: the bottom of described fixed cover 1 is provided with steam vent 7. So, in the insertion process of fixed cover 1, the gas in fixing port 4 can be discharged by steam vent 7, and then decreases the gas volume in fixing port 4, consequently facilitating the insertion of fixed cover 1, and is easy to fixed cover 1 and can be fixed on closely in fixing port 4. It is preferred that technical scheme may is that described steam vent 7 is evenly distributed on the bottom of described fixed cover 1. So, the gas in fixing port 4 can be discharged by steam vent 7 uniformly so that fixed cover 1 can insert smoothly.
Referring to accompanying drawing 1-4, a kind of vacuum suction cup assembly of the present utility model is on the basis of technique scheme, it is possible to be: the inwall interference fit of the outer ring of described fixed cover 1 and described fixing port 4. So; fixed cover 1 is firmly arranged in fixing port 4, and piston 2 serves the effect that auxiliary supports and protects, and the setting of fixed cover 1 decreases piston 2 and the mount stress of tank body 3 splicing position; and then and reduce the fracture phenomena of tank body 3, improve yield rate.
Above-mentioned only a kind of specific embodiment in this utility model is illustrated; but can not as protection domain of the present utility model; every equivalence made according to the design spirit in this utility model changes or modifies, and is all deemed to fall protection domain of the present utility model.
