Abstract
The utility model discloses an opening-closing device of an open sensor/transducer. The opening-closing device comprises a knob, a cam, an arrow part and an elastic part, and is characterized in thata sliding groove is arranged in the middle of the knob, the arrow part and the elastic part are disposed inside the sliding groove, the elastic part positioned under the arrow part is elastically connected with the arrow part, and the cam is arranged on a lower screw stem of the knob. The opening-closing device can enable the opening-closing mode of the open sensor/transducer to be simpler and more convenient, improves precision of opening-closing operation, and can ensure opening and closing to be in place accurately every time.
Description
[technical field]
The utility model relates to sensor or transmitter, particularly the closing device of open type sensor/transmitter.
[background technology]
Existing open type current transducer/sensor opening and closing part separation structure is discrete, complicated, the general modes such as screw, spring leaf, opening clip that adopt are fixed, two parts of folding disperse independent, make that open type electric current assembling process of products is loaded down with trivial details, production efficiency is low, particularly makes user's installation capability instability.
[utility model content]
For overcoming above-mentioned technological deficiency, the inventor of the utility model patent discloses easy, the accurate closing device of open type sensor/transmitter folding through studying for a long period of time.
The utility model can be realized by following scheme: the closing device of open type sensor/transmitter, comprise knob, cam, arrow spare and elastic component, it is characterized in that: in the middle of described knob, be provided with chute, described arrow spare and elastic component are arranged in the described chute, described elastic component below arrow spare and the two elasticity connect, described cam is arranged on the bottom screw rod of described knob.
Described elastic component is a spring.
On described open type sensor/transmitter shell, be provided with the locating slot that mates with the arrow portion of described arrow spare.
Described locating slot is provided with 2, is respectively opening locating slot and closed orientation groove.
The angle of described open slot and closed slots and described knob center is 90 degree.
The beneficial effects of the utility model are: (1) closing device of the present utility model can make the mode of open type sensor or transmitter folding easier, need not use any external tool and easy folding; (2) closing device of utility model is owing to be provided with folding locating slot and closed orientation groove, the user only needs arrow spare is simply shifted in the corresponding locating slot, just can realize the folding operation, improve the precision of folding operation, can guarantee that each folding all can accurately put in place; (3) closing device of utility model is simple in structure, easy to make, and cost is lower.

[embodiment]
Below in conjunction with specific embodiment the utility model is elaborated.
The utility model open type current transducer/sensor closing device structural representation as shown in Figure 1, comprise knob 1, cam 2, arrow spare 3 and elastic component 4, in the middle of described knob 1, be provided with chute 5, described arrow spare 3 and elastic component 4 are arranged on described chute interior 5, described elastic component 3 below arrow spare 4 and the two elasticity connect, described cam 2 is arranged on the bottom screw rod of described knob 1.
Its use is as follows: arrow spare 3 and elastic component 4 are placed in the chute 5 of knob 1 central authorities, the locating slot that matches with the arrow portion of arrow spare 3 is also arranged on open type current transducer/sensor outer housing, described locating slot comprises opening locating slot 6 and closed orientation groove 7, described opening locating slot 6 and closed orientation groove 7 corresponding respectively the state of closing device open and close, when needs are opened sensor or transmitter, only needing to promote arrow spare 3 downwards makes arrow spare 3 slip away out from the closed orientation groove, and rotary knob 1, turn arrow spare 3, the arrow position of arrow spare 3 is shifted in the opening locating slot 6, the arrow position that utilizes the elastic force of elastic component 4 just can promote arrow spare 3 after putting in place is stuck in the opening locating slot 6 of knob, this moment, cam 2 unclamped active side 8, can open the movable gauge head of sensor or transmitter; When needs closed sensor or transmitter, only need to promote arrow spare 3, it is just passable that arrow spare 3 is shifted to closed orientation groove 7.Cam 2 is installed on the knob 1 bottom screw rod, and along with knob 1 rotates together, when knob 1 forwarded closure state to, cam 2 was just pressing the movable gauge head 8 of sensor or transmitter; When knob 1 forwarded open mode to, cam 2 just unclamped the movable gauge head 8 of opening transmitter, thereby realized the folding of open type current transducer/sensor.
Fig. 4 is that the knob three-view diagram shows among Fig. 1, and Fig. 5 is an arrow spare three-view diagram among Fig. 1, and Fig. 6 is Fig. 1 cam three-view diagram.
In sum; although the utility model is described in detail the utility model structure by specific embodiment; but persons skilled in the art should be understood that; the foregoing description only is the description to preferred embodiment of the present utility model; but not to the restriction of the utility model protection domain; persons skilled in the art are in the disclosed technical scope of the utility model, and the variation that can expect easily is all within protection domain of the present utility model.
