Abstract
The utility model discloses a control mechanism of a reversing valve. The control mechanism of the reversing valve comprises a base, a handle assembly and a control assembly. The control assembly is installed in the base, the handle assembly comprises a handle, an outer sleeve and a pressing mechanism, the outer sleeve enters from the lower end of the handle in a sleeved mode, a connecting piece is fixedly installed at the lower end of the outer sleeve, the outer sleeve is movably connected to the control assembly through the connecting piece, the pressing mechanism is arranged in the outer sleeve, the lower end of the handle is provided with an inserting rod, a groove is formed in the base, under the action of the pressing mechanism, the inserting rod penetrates through the connecting piece and extends to the groove, and when the handle is lifted and the inserting rod is separated from the groove, the handle can be wrenched leftwards and rightwards. The control mechanism of the reversing valve has the advantages that the handle needs to be lifted and the inserting rod is made to be separated from the groove so that the handle can be wrenched and operation can be conducted, therefore, the handle is prevented from being touched by accident, and misoperation is avoided; due to the fact that the groove is deep, normal use of the control mechanism can not be influenced by a sliding groove reserved in the base by the handle and the service life of the control mechanism is prolonged.
Description
Technical field
The utility model relates to a kind of operating mechanism, especially relates to a kind of operating mechanism of selector valve.
Background technique
The operating mechanism of existing selector valve comprises pedestal, Handleset and control unit, Handleset and control unit are flexibly connected, Handleset comprises handle and hold-down mechanism, the lower end of handle is a spherical end, under the effect of hold-down mechanism, agree with mutually with the arc-shaped shallow slot on pedestal the lower end of handle, and control unit is arranged in pedestal, control unit comprises cam and briquetting, and pedestal is arranged on selector valve.The operating principle of this structure is: when handle is pulled, the lower end of handle and the arc-shaped shallow slot friction on pedestal also produce an extruding force, make hold-down mechanism compacted, handle is to top offset and leave arc-shaped shallow slot, handle is pulled, be with moving cam to a sideway swivel, the cam driven briquetting is depressed push rod component simultaneously, thereby controls selector valve.There is following defect in this structure: handle, at its lower end has positioning action with the structure that arc-shaped shallow slot on pedestal agrees with mutually for this operating device, make the handle can be because of the reason of gravity under a sideslip, but this handle is as long as a little firmly will be pulled, operator can be because produce misoperation in unconscious situation because of carelessness, may cause peril, and the effect due to hold-down mechanism, after long-term the use, handle can stay chute on pedestal, thereby cause handle to fix, operating mechanism is scrapped.
Summary of the invention
Technical problem to be solved in the utility model is to provide and a kind ofly can produce misoperation, the operating mechanism of longer service life.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of operating mechanism of selector valve, comprise pedestal, Handleset and control unit, described control unit is arranged in described pedestal, described Handleset comprises handle, overcoat and hold-down mechanism, described overcoat is inserted in from the lower end of described handle, the lower end of described overcoat is installed with link, described overcoat is flexibly connected by link and described control unit, described hold-down mechanism is arranged in described overcoat, the lower end of described handle is provided with insertion rod, be provided with groove on described pedestal, under the effect of described hold-down mechanism, described insertion rod is passed described link and is extend in the middle of described groove, when described handle is raised, when described insertion rod is left described groove, described handle can be pulled by left and right.
Described hold-down mechanism comprises cavity, spring and baffle plate, and described cavity is arranged in described overcoat, and described baffle plate is arranged on described insertion rod, and described spring is arranged between the upper bottom and described baffle plate of described cavity.
The upper end of described overcoat is equipped with rubber connector.
Described control unit comprises cam and briquetting, described cam is positioned at described pedestal, described cam, described pedestal and described link are flexibly connected by rotating shaft from inside to outside, described cam reaches the effect be fixedly connected with from vertical insertion by positioning screwn with described rotating shaft, the below of described cam is provided with two briquettings, and described briquetting left and right symmetrically is fixedly mounted in described pedestal.
Compared with prior art, the lower end that the utility model has the advantage of handle is provided with insertion rod, be provided with groove on pedestal, under the effect of hold-down mechanism, insertion rod is passed link and is extend in the middle of groove, when handle is raised, when insertion rod is left described groove, handle can be pulled by left and right, this structure is avoided because encounter because of carelessness the generation misoperation, because groove is darker, the chute that Handleset stays on pedestal can not affect the normal use of operating mechanism, has extended the working life of operating mechanism simultaneously;
When hold-down mechanism comprises cavity, spring and baffle plate, cavity is arranged in overcoat, baffle plate is arranged on insertion rod, when spring is arranged between the upper bottom of cavity and baffle plate, downward power of the handle that spring can be raised, the handle be raised is resetted, and the lower end of handle extend in the middle of groove again, prevents misoperation;
When control unit comprises cam and briquetting, cam is positioned at pedestal, cam, pedestal and link are flexibly connected by rotating shaft from inside to outside, cam reaches the effect be fixedly connected with from vertical insertion by positioning screwn with rotating shaft, the below of cam is provided with two briquettings, when the briquetting left and right symmetrically is fixedly mounted in pedestal, handle rotates band moving cam and briquetting, thereby reaches the effect of controlling selector valve.
The accompanying drawing explanation
Fig. 1 is Facad structure schematic diagram of the present utility model;
Fig. 2 is side sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Embodiment: as shown in the figure, a kind of operating mechanism of selector valve, comprise pedestal 1, Handleset 2 and control unit 3, control unit 3 is arranged in pedestal 1, Handleset 2 comprises handle 4, overcoat 5 and hold-down mechanism 6, overcoat 5 is inserted in from the lower end of handle 4, the lower end of overcoat 5 is installed with link 7, overcoat 5 is flexibly connected by link 7 and control unit 3, hold-down mechanism 6 is arranged in overcoat 5, the lower end of handle 4 is provided with insertion rod 8, on pedestal 1 fluted 9, under the effect of hold-down mechanism 6, insertion rod 8 is passed link 7 and extend in the middle of groove 9, when handle 4 is raised, when insertion rod 8 is left groove 9, handle 4 can be pulled by left and right.
