Description

Technical Field

[0001] The utility model relates to the technical field of fixing seats, and more specifically to a stable tray fixing seat. Background Art

[0002] The pallet fixing seat generally refers to the part that connects the excavator bucket (or bucket, pallet) and the excavator boom to ensure that the bucket can be firmly mounted on the excavator and allow the bucket to flip and dig through the action of the cylinder;

[0003] In the existing excavator, the structure of the connection between the bucket and the excavator boom {such as the publication (publication) number: CN216475257U, a hydraulic excavator quick-change bucket arm device}, adopts a rotating frame "quick-change bucket arm device body, connecting rod assembly respectively through a rocker (rocker is a rotating pin shaft, etc.)" and a tray fixing seat protruding on the bucket for rotation connection;

[0004] According to the above, in order to ensure the stability of the rocker after being penetrated and connected, the existing {such as public (publication) number: CN215367469U, excavator bucket and excavator}, the "ear plate" corresponding to the raised ring for installing the rocker is provided with holes for connecting and fixing the rocker with bolts, etc., but when the rocker is inserted and installed, there is generally a certain degree of tightness and it is inconvenient to insert. When performing a stable connection setting, it is necessary to align the holes on the raised ring of the rocker and the "ear plate", and when the rocker is inserted tightly, it is necessary to align one side. At this time, there is a disadvantage of inconvenient alignment. Utility Model Content

[0008] The stabilizing component includes a collar connected to the connecting hole and fixed to the tray plate, a fixing hole penetrating the collar, a screw moving in the fixing hole, and a nut threadedly connected to the screw. The pin moves in the collar, the fixing hole penetrates opposite sides of the pin, and the screw fixes the collar and the pin through the fixing hole.

[0009] It also includes a positioning groove arranged in the sleeve ring and a positioning block movable in the positioning groove. One side of the positioning groove is connected to the outside of the sleeve ring, and the outside of the positioning block is fixed to the pin shaft.

[0010] As a preferred technical solution of the utility model, the positioning groove and the positioning block or a part of the positioning block are embedded with each other.

[0011] As a preferred technical solution of the utility model, the positioning block gradually decreases in the direction of being inserted into the connecting hole.

[0021] like Figures 1 to 3 As shown, the utility model proposes: a stable pallet fixing seat, comprising two sets of symmetrically arranged pallet plates 1 (such as Figure 1 As shown, two groups of pallet plates 1 are symmetrically arranged on the bucket front and back);

[0022] The rotating frame 2 and the rotating arm 3 are located between the two sets of pallet plates 1, and the connecting hole 4 (such as Figure 2As shown, between the front and rear sides of the two groups of tray plates 1, connecting holes 4 penetrate the rotating frame 2 and the rotating arm 3 respectively);

[0023] The movable pin 5 is fitted in the connecting hole 4, and the pin 5 rotates the rotating frame 2 and the rotating arm 3 through the connecting hole 4 to connect the tray plate 1, that is, the pin 5 is movably inserted into the connecting hole 4 from front to back;

[0024] and a stabilizing component 6 for fixing the position of the pin shaft 5, which is used to fix and stabilize the position of the pin shaft 5 that penetrates into the connecting hole 4;

[0025] In order to realize the implementation and use of the above-mentioned stabilizing component 6, it is proposed that Figure 2 As shown, the specific structure and composition of the stabilizing component 6 can be as follows: the stabilizing component 6 includes a collar 61 (such as Figure 1 , 2 As shown, a collar 61 is provided only at the front end of the front tray plate 1, and the collar 61 is arranged outside the connecting hole 4 to achieve an integrated front-to-back connection. The collar 61 and the tray plate 1 can be connected by an integral molding or the like);

[0026] The fixing hole 62 (such as Figure 2 As shown, the fixing hole 62 passes through the collar 61 up and down);

[0027] The screw 63 moves in the fixing hole 62, the nut 64 is threadedly connected to the screw 63, the pin 5 moves in the collar 61, the fixing hole 62 passes through the opposite sides of the pin 5, and the screw 63 fixes the collar 61 and the pin 5 through the fixing hole 62 (such as Figure 2 As shown, the screw 63 penetrates the fixing hole 62 from top to bottom. During this process, the screw 63 penetrates the collar 61 and the pin 5 at the same time. The inserted end of the screw 63 passes out of the fixing hole 62 and is threadedly connected with a nut 64 and pressed against the collar 61 to fix it);

[0028] It also includes a positioning groove 7 provided in the collar 61, and a positioning block 8 movable in the positioning groove 7, one side of the positioning groove 7 is connected to the outside of the collar 61, and the outside of the positioning block 8 is fixed to the pin 5;

[0029] like Figure 2 As shown, the positioning groove 7 is arranged in the collar 61, and the positioning groove 7 passes through the collar 61 at the front end. When the pin shaft 5 is inserted into the connecting hole 4 in the collar 61, the positioning block 8 is inserted into the positioning groove 7, so that the relatively connected fixing holes 62 on the collar 61 and the pin shaft 5 can be determined, simplifying the installation operation process;

[0030] The positioning groove 7 is interlocked with the positioning block 8 or a part of the positioning block 8 (i.e., the front-to-back length of the positioning block 8 is not less than the front-to-back depth of the positioning groove 7, and when the positioning block 8 is inserted into the positioning groove 7, it provides interlocking support stability, improves the stability of assembly, and prevents the pin shaft 5 from being over-inserted, further simplifying the installation operation process);

[0031] The positioning block 8 gradually decreases in size toward the direction of insertion into the connecting hole 4 (eg Figure 2 , 3 As shown, at the same time, the positioning block 8 is placed in the positioning groove 7 using a structure from small to large, which can reduce contact resistance and facilitate placement).

[0032] When the above-mentioned "the positioning groove 7 is interlocked with the positioning block 8 or a part of the positioning block 8" is not set, it is preferred that a limit plate 9 is fixedly arranged on the periphery of the pin shaft 5 (compared with the positioning groove 7 and the positioning block 8, the structure is simpler);

[0033] The outer side of the limiting plate 9 is fitted with the sleeve ring 61 (such as Figure 2 As shown, when the pin shaft 5 is inserted backward into the connecting hole 4, the rear end of the limiting plate 9 fits against the front end of the sleeve ring 61 to provide a barrier for the insertion distance, prevent excessive insertion, and further simplify the installation operation process).

[0034] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
