Description
Technical field
The utility model relates to switching technique field, and one prevents shift knob from touching device by mistake specifically.
Background technology
Solar silicon wafers cutting need carry out cost control by mortar recovery system, the shift knob of the equipment of work on the spot is exposed on switch panel, there is staff's touching switch button by mistake, cause the problem that equipment suddenly stops or opening, there is great potential safety hazard, also bring unnecessary trouble and loss to work.
Summary of the invention
Technical problem to be solved in the utility model is: provide one to prevent shift knob from touching device by mistake, is touched the problem causing and suddenly stop or opening by mistake, eliminate safe hidden trouble to solve field apparatus because of shift knob.
For solving the problems of the technologies described above, the technical solution of the utility model is: prevent shift knob from touching device by mistake, comprise: the transparent protective shield of one end open, described protective cover is cube or rectangular shape, the openend of described protective cover is provided with magnetic frame plate, the surface of described magnetic frame plate and the first side wall of described protective cover are rotationally connected, the second sidewall relative with described the first side wall on described protective cover is provided with the first pin-and-hole, described magnetic frame plate is provided with second pin-and-hole suitable with described first pin-and-hole, described first pin-and-hole and described second pin-and-hole coaxial, run through in described first pin-and-hole and described second pin-and-hole and have bearing pin.
Improve as one, one end of described bearing pin is provided with the block piece preventing bearing pin slippage.
Improve as one, the material of described protective cover is acrylic.
Owing to have employed technique scheme, the beneficial effects of the utility model are: because transparent protective cover is cube or rectangular shape, magnetic frame plate is provided with at the openend of protective cover, the surface of magnetic frame plate and the first side wall of protective cover are rotationally connected, the second sidewall relative with the first side wall on protective cover is fixed with the first pin-and-hole, correspondingly, magnetic frame plate is fixed with the second pin-and-hole with the first pin-and-hole adaptation, first pin-and-hole and the second pin-and-hole are coaxial, and running through in the first pin-and-hole and the second pin-and-hole has bearing pin; During use, magnetic frame plate is adsorbed on shift knob panel, shift knob is covered in protective cover, because bearing pin runs through the first pin-and-hole and the second pin-and-hole, make to be fixedly connected with between protective cover and magnetic frame plate, protective cover protection switch button can not be caused stopping suddenly or the unlatching of equipment by touching by mistake, what ensure production carries out the safety with staff smoothly; Take off bearing pin, protective cover of outwarding winding, can operate shift knob.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is the cutaway view of A-A in Fig. 1;
In figure: 1-magnetic frame plate; 11-second pin-and-hole; 12-endoporus; 2-protective cover; 21-first pin-and-hole; 22-the first side wall; 23-second sidewall; 3-bearing pin; 31-block piece; 4-hinge.
Embodiment
Below by embodiment and accompanying drawing, the utility model is described in further detail.
As Fig. 1, Fig. 2 and Fig. 3 jointly shown in, one prevents shift knob from touching device by mistake, comprise the protective cover 2 of one end open, protective cover 2 is in cuboid or cubic shaped, magnetic frame plate 1 is provided with at the openend of protective cover 2, magnetic frame plate 1 is provided with endoporus 12, the first side wall 22 of protective cover 2 is rotationally connected by hinge 4 with the surface of magnetic frame plate 1, the second sidewall 23 relative with the first side wall 22 on protective cover 2 is fixed with the first pin-and-hole 21, magnetic frame plate 1 is fixed with second pin-and-hole 11 suitable with the first pin-and-hole 21, first pin-and-hole 21 and the second pin-and-hole 11 are coaxial and diameter is identical, the bearing pin 3 having and be slidably connected with the first pin-and-hole 21 and the second pin-and-hole 11 is run through in first pin-and-hole 21 and the second pin-and-hole 11, the block piece 31 that diameter is greater than the diameter of the first pin-and-hole 21 is fixed with in one end of bearing pin 3, block piece 31 goes out the first pin-and-hole 21 and the second pin-and-hole 11 for preventing bearing pin 3 slippage.
The material of protective cover 2 is preferably transparent acrylic, so that observe shift knob.
In use; magnetic frame plate 1 is adsorbed on shift knob panel; shift knob is covered in protective cover 2; bearing pin 3 runs through the first pin-and-hole 21 and the second pin-and-hole 11; make to be fixed together between protective cover 2 and magnetic frame plate 1; protection switch button can not because being caused stopping suddenly or the unlatching of production equipment by not touching, what be beneficial to production carries out the safety with safeguard work personnel smoothly.
When needing switch push-botton operation, take off bearing pin 3, protective cover 2 of outwarding winding, can operate shift knob.
In sum, the utility model prevents shift knob from touching device by mistake, can not only effectively prevent shift knob from not touching, and solves the field apparatus problem that suddenly stops or opening, and can operation button switch easily, easy to use.
