[0033] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a stand plate protection device for a loader bucket of the utility model in conjunction with the accompanying drawings.

[0034] like Figure 1-Figure 5 As shown, a stand plate protection device for a loader bucket of the utility model comprises a bucket 1 capable of shoveling and excavating soil and a protective plate 2 arranged on the bucket 1. The bucket 1 is blocked on both sides by two groups of relatively arranged stand plates 11, and the protective plate 2 is connected to the surface of the stand plate 11 in a detachable manner, so that the damaged protective plate 2 can be replaced and maintained.

[0035] Specifically, the detachable method is to install the limit blocks 12 on the two side surfaces of the station board 11 and the slider 21 at the bottom of the protective plate 2, and the slider 21 is inserted into the slide groove 123 formed between the limit blocks 12 in a sliding manner, and then can be inserted and installed in a sliding manner when the protective plate 2 is installed. There are bolt holes 122 passing through the surface of the limit blocks 12, and then two sets of opposite bolts 3 can be respectively penetrated to the fastening area 124, and then the nuts 4 can be threadedly connected with the bolts 3 to achieve fastening and locking.

[0036] The end surface of the limit block 12 located in the fastening area 124 is provided with a rotation groove 121 inwardly, and the rotation rings 41 provided at the two ends of the nut 4 can be hinged and rotated by the rotation groove 121. At the same time, the two ends of the nut 4 are provided with bidirectional threads 42 threadedly connected to the bolts 3, and then after the nut 4 is rotated, the bolts 3 threadedly connected to the two ends can move toward each other at the same time, and then the effect of fast tightening can be achieved.

[0037] like Figure 6-Figure 7 As shown in the figure, it is a first embodiment of the auxiliary through-through structure, the surface of the slider 21 is penetrated with a through-through hole 1 211 for the bolt 3 to penetrate, and the openings on both sides of the through-through hole 1 211 are provided with inclined grooves 1 212 in an inclined structure. Then, when one end of the bolt 3 moves to the opening of the inclined groove 1 212, since the inclined groove 1 212 is provided in an inclined structure, when there is a certain misalignment between the through-through hole 1 211 and the bolt hole 122, the bolt 3 can be smoothly penetrated, and the position between the through-through hole 1 211 and the bolt hole 122 can be adjusted in time.

[0038] like Figure 8-Figure 10 As shown, it is a second embodiment of the auxiliary through-hole structure, a second through-hole 213 is provided through the surface of the slider 21, and the second through-hole 213 is provided in a straight slot-shaped structure, and a pipe sleeve 5 that can rotate with a pin 51 as an axis is hinged from the inside of the second through-hole 213, and two inclined grooves 52 are respectively provided at the openings of the two ends of the pipe sleeve 5. Therefore, after the pipe sleeve 5 and the bolt hole 122 are concentrically aligned with each other and have a certain deviation and misalignment, as one end of the bolt 3 penetrates into the pipe sleeve 5, the deviation between the pipe sleeve 5 and the bolt hole 122 can be corrected by the rotatable pipe sleeve 5, so as to facilitate the penetration of the bolt 3.

[0039] The working principle of a stand plate protection device for a loader bucket: when the guard plate 2 on the stand plate 11 needs to be installed, the slider 21 provided at the bottom of the guard plate 2 can be slid into the slide groove 123, and then one end of the bolt 3 can pass through the bolt hole 122 and the auxiliary penetration structure in the first and second embodiments, and then the two-way threads 42 provided at the ends of the nut 4 can be threadedly connected with the bolt 3, and then they are moved toward each other at the same time, and then the effect of rapid tightening can be achieved. At the same time, when one end of the bolt 3 passes through the auxiliary penetration structure, the deviation of the penetration can be adjusted in time through the auxiliary penetration structure.

[0040] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
