Description
Technical field
The utility model high-voltage switch gear, specifically refers to a kind of single channel of connection fast high-voltage switch gear.
Background technique
High-voltage switch gear is often applied in the equipment such as washing machine, converts electric control signal to export for the hydraulic pressure in testing pipes and by this hydraulic signal.Existing a kind of high-voltage switch gear, its structure includes shell, described shell is provided with intake tunnel, exhalant canal, hydraulic pressure chamber, the diaphragm of the top in described hydraulic pressure chamber, also sensitive switch is provided with in described shell, diaphragm and sensitive switch are linked, as shown in China Patent No. 201420297741.6.
The high-voltage switch gear of this structure, needing on its shell arranges intake tunnel and exhalant canal, therefore, when practical application, need intake tunnel to be connected with the water pipe of outside respectively with exhalant canal, tie point is many, connects inconvenient, and tie point is many also means that leak point is many, design unreasonable.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provide a kind of vibrational power flow rationally, hydraulic pressure sample acquisitions pipeline is easy to connect connects single channel high-voltage switch gear fast reliably.
For achieving the above object, the technical solution of the utility model is the shell including upper cover and base formation, hydraulic pressure chamber is provided with in described base, the top capping in this hydraulic pressure chamber is provided with flexible sheet, be provided with sensitive switch in described shell, the contact of described flexible sheet and sensitive switch is linked, and described base is provided with fast connecting pipe, the inner of this fast connecting pipe communicates with hydraulic pressure chamber, and the outer end of this fast connecting pipe is butt end.
By this setting, employing outer end is butt end, the inner directly communicates with hydraulic pressure chamber thus forms detects single pass fast connecting pipe, when the utility model as installed, considerably reduces the difficulty of docking, installs simple and convenient, and install good airproof performance.
Further setting be described fast connecting pipe outer wall on offer the spaced circular groove of multiple tracks, be arranged with O RunddichtringO in this circular groove, and the diameter of the longitudinal section of O RunddichtringO is greater than the degree of depth of circular groove.By this setting, be convenient to realize fast connecting pipe to be plugged on the inwall of other test tubes to be checked, realize sealing and stablize rapid abutting joint.
Further setting is that between described upper cover and base, crimping is fixed and is positioned at the connecting base of the top of flexible sheet mutually, relative to the linking bore being provided with upper and lower conducting above the center region of flexible sheet on this connecting base, linkage board is hinged with relative to the top of connecting base in upper cover, this linkage board is fixedly installed the interlock seat being positioned at and being connected bore, link in the lower end surface of this interlock seat and the upper-end surface of flexible sheet, the interlock upper-end surface of seat and the contact of sensitive switch are linked, described linkage board is provided with spring seat relative to the opposite side of its rounded end, Returnning spring is provided with between this spring seat and inner roof wall of upper cover.By this setting, the reliable and stable linkage structure of the contact of a kind of flexible sheet and sensitive switch is provided, improves the stability of product.
In sum, the utility model has the advantages that vibrational power flow is reasonable, dock reliable and stable, easy to operate.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
