Abstract
The utility model relates to a rotatable double-airproof scene switch operating mechanism for an electric device, which comprises a case body, a rotating shaft, and microswitches. Openings are arranged on the case body, the rotating shaft on which a double O-shaped ring is arranged is arranged in the openings. The top part of the rotating shaft is provided with a slot in which a dial board is arranged. A switch support is arranged in the upper cavity of the case body, and provided with microswitches. The dial board is arranged at the middle position of the two microswitches through a tension spring, and the rotating shaft protruding out of the top part of the case body is provided with a switch suspension arm. The utility model has the advantages that the airproof performance can be achieved by more IP 67 with good airproof performance, in addition an additional switch button light box is excused, the switch operating mechanism can be used as the standard device to supply the user, thereby being not only convenient for a user to use, but also reducing the price of the product and the load of the user.
Description
Technical field
The utility model belongs to industrial valve technology field, particularly relates to a kind of simple in structure, good airproof performance and cheap electric device with the on-the-spot switch operating mechanism of rotary type double containment.
Background technology
Field adjustable for ease of electrically operated valve, maintenance and upkeep operation, valve user and pipeline engineering user often require the electric installation of electrically operated valve to possess on-the-spot switching manipulation function, electrically operated valve manufacturer has proposed multiple solution at present, typical settling mode has two kinds of structures, one, be in the electric installation stroke moment chamber of electrically operated valve, two sensitive switches to be set, two circular holes are made a call in the position of corresponding two sensitive switches on the case cover, and two cylinder axis of being with springs are set, operating personnel press cylinder axis with hand outside to inside from the case cover and press the switching manipulation that the sensitive switch contact is realized electrically operated valve.Owing to perforate on the case cover has destroyed the sealing in stroke moment chamber, and then influenced the complete machine safeguard function of electrically operated valve, made it can only reach IP54.Its two, perforate extra switch Push-button lamp box on the casing of same direction side, stroke moment chamber is realized the switching manipulation of electrically operated valve then by the button that is provided with in the lamp box.The shortcoming of this kind structure is: owing to increase the switch lamp box, cause strengthening the cost of product, so not only increased user's production and purchase cost, also destroyed the aesthetic appearance of electrically operated valve complete machine simultaneously.
Summary of the invention
The electric device on-the-spot switch operating mechanism of rotary type double containment that the utility model provides a kind of both economic and has good seal performance for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The electric device on-the-spot switch operating mechanism of rotary type double containment, mainly comprise casing, rotating shaft and sensitive switch, it is characterized in that: on casing, have the hole that installs rotating shaft, in the hole, be coated with the rotating shaft that two O shape circles are housed on it, have a groove in the rotating shaft top, be equipped with in this groove and dial plate, in the casing epicoele switch bracket is installed, sensitive switch is housed on the switch bracket, the plate of dialling that is installed on the rotating shaft places two sensitive switch centre positions by extension spring, on the rotating shaft of protrusion casing the switch spiral arm is housed.
The utility model can also adopt following technical scheme:
Described rotating shaft, switch spiral arm and group plate are by back-up ring, screw and sell coaxial fastening.
Advantage and the good effect that the utlity model has are: because the utility model has adopted perforate on casing, and in the hole, install the rotating shaft that two O shapes circles are housed on it, and axially inside and outside fastening structure makes it have excellent sealing performance, and its sealing can reach more than the IP67; The utility model has been removed extra switch Push-button lamp box from addition, provides the user with described switch operating mechanism as standard configuration, not only can be user-friendly to, and has also reduced product price simultaneously and has alleviated user's burden.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Among the figure: 1, casing; 2, rotating shaft; 3, switch spiral arm; 4, dial plate; 5, sensitive switch; 6, extension spring, 7, switch bracket; 8, two O shape circles; 9, back-up ring; 10, screw; 11, screw; 12, pin.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, the electric device on-the-spot switch operating mechanism of rotary type double containment, mainly comprise casing 1, rotating shaft 2 and sensitive switch 5, on casing 1, have the hole that installs rotating shaft 2, in this hole, be coated with the rotating shaft that two O shape circles 8 are housed on it, have a groove in the rotating shaft top, be equipped with in this groove and dial plate 4, switch bracket 7 is installed in the casing epicoele, sensitive switch 5 is housed on the switch bracket, the plate 4 of dialling that is installed on the rotating shaft places the centre position of two sensitive switches 5 to locate by extension spring 6, on the rotating shaft at protrusion casing top switch spiral arm 3 is housed.Described rotating shaft 2, switch spiral arm 3 and dial plate 4 by back-up ring 9, screw 10,11 and sell 12 realize coaxial fastening, so not only can prevent rotating shaft, switch spiral arm and dial moving axially of plate, can guarantee the excellent sealing effect in electric device stroke moment chamber again.
Operation principle of the present utility model is:
During operation, left rotation and right rotation switch spiral arm 3 is dialled the contact that plate 4 can press sensitive switch 5 to certain angle, and then realizes the switching manipulation of electric device.Because the effect of extension spring 6, behind trip switch spiral arm 3, rotating shaft 2 and group plate 4 will be got back to the centre position of sensitive switch 5 automatically.The motor switch direction of switch spiral arm left rotation and right rotation correspondence is generally a left side and opens right closing.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
