Abstract
The utility model relates to nut structure, provide a kind of structure simple, the wearing and tearing of tightening nut and wear-resisting steel plate can be slowed down, increase the service life, reduce the protective nut structure for shot blast room of frequency of maintenance, when solving the ball blast operation existed in prior art, shot can directly impact in the gap between nut and wear-resisting steel plate, nut is worn and torn gradually, gap constantly increases, the technical problem directly causing that wear-resisting steel plate comes off time serious etc., it comprises the tightening nut be screwed on shot blast room wear-resisting steel plate positioning stud, on described tightening nut, interworking is covered with metal coating lid, the opening end of metal coating lid horizontally outward extends to form flange, and the internal surface level of flange is connected to corresponding shot blast room wear-resisting steel plate on the surface.
Description
Technical field
The utility model relates to a kind of nut structure, particularly relates to a kind of wearing and tearing slowing down shot blast room wear-resisting steel plate tightening nut and wear-resisting steel plate, increases the service life, and reduces the protective nut structure for shot blast room of frequency of maintenance.
Background technique
The inner wear-resisting steel plate of shot blast room needs nut to be fixed on side wall surface, owing to there is gap between nut and wear-resisting steel plate, therefore when carrying out ball blast operation, shot can directly impact in the gap between nut and wear-resisting steel plate, nut is worn and torn gradually, gap constantly increases, and directly causes wear-resisting steel plate to come off time serious.
Summary of the invention
The utility model mainly provides the wearing and tearing that a kind of structure is simple, can slow down tightening nut and wear-resisting steel plate, increase the service life, reduce the protective nut structure for shot blast room of frequency of maintenance, when solving the ball blast operation existed in prior art, shot can directly impact in the gap between nut and wear-resisting steel plate, nut is worn and torn gradually, gap constantly increases, the technical problem directly causing that wear-resisting steel plate comes off time serious etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of protective nut structure for shot blast room; comprise the tightening nut be screwed on shot blast room wear-resisting steel plate positioning stud; on described tightening nut, interworking is covered with metal coating lid; the opening end of metal coating lid horizontally outward extends to form flange, and the internal surface level of flange is connected to corresponding shot blast room wear-resisting steel plate on the surface.By shroud metal coating lid on tightening nut; and the flange level of being extended by metal coating lid edge is connected on shot blast room wear-resisting steel plate; make the complete sealing cover of tightening nut in metal coating lid; thus avoid the impact of shot to tightening nut; it also avoid shot to impact the gap between tightening nut and shot blast room wear-resisting steel plate; thus it is not damaged to protect tightening nut, extend the working life of tightening nut.
As preferably, described tightening nut is coaxially inlaid in the mesopore of metal coating lid.Can be embedded in metal coating lid by tightening nut in advance during use and install, the means of fixation of setting-in is simple and reliable, and disassembling, assembling and replacing is convenient.
As preferably, described metal coating lid is cylindrical, and the metal coating lid end relative with tightening nut is round-corner transition.Columniform metal coating lid is easily processed, and during its edge employing round-corner transition, avoids corner angle to damage, and carries out batch process by mould, save manufacture cost.
As preferably, in the material of described metal coating lid, Cr content is more than or equal to 3%.By adding Cr in the material of metal coating lid, improve the wear resistance of metal coating lid.
Therefore; protective nut structure for shot blast room of the present utility model has following advantage: make the complete sealing cover of tightening nut in metal coating lid by metal coating lid; thus avoid the impact of shot to tightening nut and tapped hole; thus avoid that tightening nut is lax to come off; metal coating lid disassembling, assembling and replacing is convenient; extend the working life of tightening nut, improve the safety reliability of shot blast room.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of protective nut structure for shot blast room of the utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in Figure 1, a kind of protective nut structure for shot blast room of the present utility model, comprise the tightening nut 1 be screwed on shot blast room wear-resisting steel plate 4 positioning stud 5, on tightening nut 1, interworking shroud metal coating lid 2, metal coating lid 2 is cylindrical, and metal coating lid 2 outer end relative with tightening nut 1 is round-corner transition, the opening end of metal coating lid 2 horizontally outward extends to form flange 3, and the internal surface level of flange 3 is connected to corresponding shot blast room wear-resisting steel plate 4 on the surface, tightening nut 1 is coaxially inlaid in the mesopore of metal coating lid 2, thus make tightening nut 1 be encapsulated between metal coating lid 2 and shot blast room wear-resisting steel plate 4, in order to improve the wear resistance of metal coating lid, in the material of metal coating lid 2, Cr content is greater than 3%.
Specific embodiment described herein is only to design of the present utility model explanation for example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
