The service life and equipment reliability of operation of band and safety.
Utility model content
In view of this, passing through nut portion the technical problem to be solved by the utility model is to provide a kind of tooth mouth screw
The spike that turns over enter elevator belt, while non-slip rubber ring increases friction, and fastening assembly fastens winnowing pan, avoids previous screw fastening loosely
Trouble.
In order to solve the above-mentioned technical problem, the utility model discloses a kind of tooth mouth screws comprising nut portion；It extends
The cone neck of nut portion one end, cone neck are gradually thick along inner ring by outer ring；The threaded shank of connection cone neck, threaded shank have outer spiral shell
Line；And it is matched with the fastening assembly of threaded shank；Wherein, nut portion ring, which sets three and turns down to cone neck, turns over point；Bore neck ring
If groove, groove is fitted into non-slip rubber ring.
According to one embodiment of the utility model, wherein above-mentioned depth of groove is 2mm.
According to one embodiment of the utility model, wherein above-mentioned non-slip rubber ring has the anti-skidding salient point at two circle intervals.
According to one embodiment of the utility model, wherein above-mentioned fastening assembly includes the bowl-type rubber pad for being successively sheathed on threaded shank
Piece, spring shim and hex nut, bowl-type gasket is close to nut portion.
According to one embodiment of the utility model, wherein the above-mentioned point that turns over is higher than cone neck.
Compared with prior art, the utility model can be obtained including following technical effect:
Enter elevator belt by the spike that turns in nut portion, while non-slip rubber ring increases friction, fastening assembly fastens winnowing pan, keeps away
Exempt from the trouble of previous screw fastening loosely.
Certainly, any product for implementing the utility model must be not necessarily required to reach all the above technology effect simultaneously
Fruit.
Detailed description of the invention
Attached drawing described herein is used to provide a further understanding of the present invention, and constitutes one of the utility model
Point, the exemplary embodiment of the utility model and the description thereof are used to explain the utility model, does not constitute to the utility model
Improper restriction.In the accompanying drawings:
Fig. 1 is the tooth mouth screw schematic diagram of the utility model embodiment；
Fig. 2 is the tooth mouth screw top view of the utility model embodiment.
Appended drawing reference
Nut portion 10 bores neck 20, threaded shank 30, fastening assembly 40, bowl-type gasket 41, spring shim 42, hex nut
43, turn over point 50, non-slip rubber ring 60, anti-skidding salient point 61.
Specific embodiment
The embodiments of the present invention is described in detail below in conjunction with accompanying drawings and embodiments, whereby to the utility model
How applied technology method solves technical problem and reaches the realization process of technical effect to fully understand and implement.
It is the tooth mouth screw schematic diagram of the utility model embodiment please also refer to Fig. 1 and Fig. 2, Fig. 1；Fig. 2 is that this is practical
The tooth mouth screw top view of new embodiment.As shown, a kind of tooth mouth screw includes nut portion 10；Extend nut portion 10 1
The cone neck 20 at end, cone neck 20 are gradually thick along inner ring by outer ring；The threaded shank 30 of connection cone neck 20, threaded shank 30 have outer spiral shell
Line；And it is matched with the fastening assembly 40 of threaded shank 30；Wherein, nut portion 10 ring, which sets three and turns down to cone neck 20, turns over point
50；Cone 20 ring of neck sets groove, and groove is fitted into non-slip rubber ring 60.
Tooth mouth screw provided by the utility model is for installing winnowing pan to elevator belt, wherein nut portion 10 at round pie,
Screwed threaded shank 30 is connected by boring neck 20, molds the basic body of bolt, to wear elevator belt, and meanwhile it is tight
Gu component 40 fastens winnowing pan to elevator belt in the other end, installation is completed.In the present embodiment, 10 surrounding ring of nut portion has been set
Away from three turn over point 50, turn over point 50 and be higher than cone neck 20, use nail and set elevator belt, improve stability.In addition, cone neck 20 is by outer
, tapering design gradually thick along inner ring is enclosed, the intensity for improving the threaded shank 30 for playing the role of main carrying is helped, gradient is reinforced, avoided
Fracture damage.
Cone 20 ring of neck sets the groove of chimeric non-slip rubber ring 60, depth of groove 2mm, to position chimeric anti-slip rubber
Circle 60 increases the friction in nut portion 10 and elevator belt.In a wherein embodiment, non-slip rubber ring 60 has two circle intervals
Anti-skidding salient point 61 reduces compression area, improves stress friction, reinforces stablizing.
Fastening assembly 40 includes the bowl-type gasket 41, spring shim 42 and hex nut 43 for being successively sheathed on threaded shank 30,
Bowl-type gasket 41 is close to nut portion 10.Bowl-type gasket 41 arches upward at bowl-type to spring shim 42, can sufficiently cover winnowing pan, bullet
The 42 elasticity adjustment of spring gasket, eventually by hex nut screw threads for fastening, stability is strong.
Several preferred embodiments of the present invention have shown and described in above description, but as previously described, it should be understood that this
Utility model is not limited to forms disclosed herein, and should not be regarded as an exclusion of other examples, and can be used for various
