Abstract
The utility model discloses an abrasion-resistant and corrosion-resistant guard plate which comprises a guard plate body (1). A plurality of bolt holes are arranged on the guard plate body (1). The abrasion-resistant and corrosion-resistant guard plate is characterized in that first holding portions (2.1) for holding bolt heads in the bolt holes (2) are in polygon structures matched with the shapes of the bolt heads. The first holding portions for holding the bolt heads in the bolt holes of the abrasion-resistant and corrosion-resistant guard plate are in the polygon structures matched with the shapes of the bolt heads, so that the bolt heads fit with the first holding portions closely and gaplessly, bolts cannot rotate in the bolt holes and are less easy to loosen even if an excavator vibrates sharply, and the abrasion-resistant and corrosion-resistant guard plate can be fixed on the excavator firmly.
Description
Technical field
The utility model relates to the accessory on a kind of excavator, specifically is a kind of wear resistant corrosion resistant backplate.
Background technology
The wear resistant corrosion resistant backplate generally all is installed, in order to the significant points of protection excavator on the excavator.The wear resistant corrosion resistant backplate of prior art; Comprise panel reality; Panel reality is provided with a plurality of bolts hole, and the cooperation through screw bolt and nut can be fixed on the wear resistant corrosion resistant backplate on the excavator, and the first ccontaining position that is used for the receive bolts head in the said bolt hole is a cylindrical structural.The problem of its existence is: the head of bolt generally all is a polygonized structure, and bolt is packed in the bolt hole, and wherein the head captured of bolt is in the first ccontaining position; But because the head of bolt is a polygonized structure, and the first ccontaining position is a cylindrical structural, in conjunction with the time have a gap; Excavator can shake when work; The wear resistant corrosion resistant backplate also can and then shake simultaneously, and the time one is long, and bolt can rotate because of vibrations in bolt hole; Bolt is in a single day loosening will to make the wear resistant corrosion resistant backplate come off from excavator, influences the operate as normal of excavator.
The utility model content
The technical problem that the utility model will solve provides a kind of bolt and in bolt hole, is difficult for becoming flexible, and can be fixed on the wear resistant corrosion resistant backplate on the excavator firmly.
In order to achieve the above object; The technical scheme that the utility model provides is: a kind of wear resistant corrosion resistant backplate; Comprise panel reality; Panel reality is provided with a plurality of bolts hole, the polygonized structure that the first ccontaining position that is used for the receive bolts head in the said bolt hole is complementary for the shape with bolt head.
After adopting technique scheme; The utility model compared with prior art; Have the following advantages: the first ccontaining position that is used for the receive bolts head in the bolt hole of the utility model wear resistant corrosion resistant backplate makes the bolt head and the first ccontaining position cooperate closely no gap for the polygonized structure that the shape with the head of bolt is complementary; Even excavator shakes severely again; Bolt can not rotate in bolt hole yet, is difficult for becoming flexible, and the wear resistant corrosion resistant backplate is fixed on the excavator firmly.
As improvement, the top of said bolt hole is provided with small top and big bottom groove, and the lower end of groove links to each other with the upper end at the first ccontaining position.This structure can play the guiding role to bolt, makes the easier for installation of bolt, and the existence of this structure simultaneously makes whole bolt be embedded in panel reality inside, and difficult colliding with is more firm regularly.
Description of drawings
Fig. 1 is the structural representation of the utility model wear resistant corrosion resistant backplate.
Fig. 2 is bolt hole and the absolute construction sketch map of groove in the utility model wear resistant corrosion resistant backplate.
Shown in the figure: 1, ccontaining position, the ccontaining position of panel reality 2, bolt hole 2.1, first 2.2, second 3, groove.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain.
Like Fig. 1, shown in Figure 2: a kind of wear resistant corrosion resistant backplate, comprise panel reality 1, panel reality 1 is provided with a plurality of bolts hole 2, and bolt hole 2 comprises the first ccontaining position 2.1 and the second ccontaining position 2.2 that is used for ccontaining screw rod that is used for the receive bolts head.The polygonized structure that the said first ccontaining position 2.1 is complementary for the shape with bolt head.The top of said bolt hole 2 is provided with small top and big bottom groove 3, and the lower end of groove 3 links to each other with the upper end at the first ccontaining position 2.1.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the manual, must confirm its technical scope according to the claim scope.
Claims (2)
1. wear resistant corrosion resistant backplate; Comprise panel reality (1); Panel reality (1) is provided with a plurality of bolts hole (2), it is characterized in that: the polygonized structure that the first ccontaining position (2.1) that is used for the receive bolts head in the said bolt hole (2) is complementary for the shape with bolt head.
2. wear resistant corrosion resistant backplate according to claim 1 is characterized in that: the top of said bolt hole (2) is provided with small top and big bottom groove (3), and the lower end of groove (3) links to each other with the upper end at the first ccontaining position (2.1).
