Abstract
The invention provides an anti-loose installation device which can prolong the service life of a vibrating machine body and a vibrating motor. The anti-loose installation device comprises a bolt, wherein the bolt is provided with a first nut and a second nut which are matched with the bolt; the first and second nuts are spliced together; and the contacted surfaces of the first and second nuts are conical surfaces.
Description
Technical field
The present invention relates to a kind of erecting device, be specifically related to a kind of locking erecting device, the installation that is used for the vibratory equipment vibrating motor is fastening locking.
Background technique
At present the vibrating source of the most of vibratory equipments of China adopts vibrating motor, thus the installation precision of vibrating motor and fastening locking be a very important step.The traditional design vibrating motor be fastened with double nuts structure, locking nut structure and thrust pad block structure.
Traditional design vibrating motor construction bolt fastening structure can play fastening locking effect at short notice, but in a long time or under the large excitation force high frequency effect still difficulty avoid the bolt looseness phenomenon.The vibrating motor clamping bolt is in case loosening, do not discovering continuation use equipment in the situation, very serious to vibration body and vibrating motor itself destruction, the vibrating motor clamping bolt is loosening to be damaged vibrating motor footing attachment face, mounting hole is pulled into ellipse, can't use at all, damage such as the whole body of evil idea that continues to use, therefore develop a kind of novel vibrating motor construction bolt fastening structure and be necessary.
Summary of the invention
In order to overcome the loosening destruction to vibration body and vibrating motor itself of vibrating motor in the prior art, the invention provides a kind of locking erecting device, can improve and vibrate body and vibrating motor working life.
To achieve these goals, the present invention is by the following technical solutions:
A kind of locking erecting device comprises bolt, and described bolt is provided with the first nut with matching and the second nut, and the first nut and the second nut are plugged in together, and the first nut and contacted of the second nut are the conical surface.
Further, the first nut comprises nut portions and connecting sleeve section, has the first screw with internal thread that cooperates with bolt in nut portions and the connecting sleeve section, and connecting sleeve section is the frustum structure.
Further, the second nut inside has the second screw and frustum hole; The second screw cooperates with bolt, and has internal thread; Frustum hole and connecting sleeve section structure, shape and size are corresponding.
Further, along the frustum taper direction a plurality of openings are arranged in the connecting sleeve section.
Further, bolt is T bolt.
Beneficial effect of the present invention:
The first nut and the second nut are plugged in together, and by cone match, can effectively resist loosening under vibrational state of each fastening piece, can improve vibration body and vibrating motor working life.
Description of drawings
Fig. 1 is the selected embodiment's of the present invention mounting structure schematic diagram.

Fig. 3 is the structural representation of the second nut.
Among the figure 1, bolt, the 2, first nut, the 3, second nut, 4, the body mounting plate, 5, the vibrating motor base, 6, the conical surface, 201, nut portions, 202, opening, 203, connecting sleeve section, the 204, first screw, the 301, second screw, 302, the frustum hole.
Embodiment
Understand for the ease of those skilled in the art, below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
With reference to the accompanying drawings 1, a kind of locking erecting device comprises bolt 1, and described bolt 1 is provided with the first nut 2 with matching and the second nut 3, the first nuts 2 and the second nut 3 and is plugged in together, and the first nut 2 and 3 contacted on the second nut are the conical surface 6.
With reference to the accompanying drawings 2, the first nut 2 comprises nut portions 201 and connecting sleeve section 203, has the first screw 204 with internal thread that cooperates with bolt 1 in nut portions 201 and the connecting sleeve section 203, connecting sleeve section 203 is the frustum structure, and along the frustum taper direction a plurality of openings 202 are arranged in the connecting sleeve section 203, opening 202 makes the first nut 2 have locking function.
3, the second nuts, 3 inside have the second screw 301 and frustum hole 302 with reference to the accompanying drawings; The second screw 301 cooperates with bolt 1, and has internal thread; Frustum hole 302 is corresponding with connecting sleeve section 203 structures, shape and size.
Just vibrating motor base 5 and body mounting plate 4 are close to first during use, put into bolt 1, put into first the first nut 2 and tighten (pretightening force calculates according to the yield limit of the excitation force of vibrating motor and nut material) with certain pretightening force, and then put into the second nut 3
Use identical pretightening forceTighten, the present invention has pretension and locking function can be resisted its becoming flexible under vibrational state effectively.Loosening by facts have proved that this structure can make vibrating motor reach 1 year, improved vibration body and vibrating motor working life.
Above embodiment only is used for illustrating that technological scheme of the present invention is not intended to limit; although by embodiment the present invention is had been described in detail; under the field personnel should make amendment or the part technical characteristics is equal to replacement with reference to concrete mode of the present invention; but under the spirit that does not break away from technical solution of the present invention, above-mentioned change or be equal to replacement and should belong in the technological scheme scope that the present invention asks for protection.
