Description

Technical Field

[0001] The utility model relates to the technical field of gear plates, and more specifically to a gear plate for a dump truck. Background Art

[0002] A dump truck is a special vehicle with a tiltable bucket that is used to transport materials over short distances. A "bucket"-shaped container is installed on the body of the vehicle, which can be flipped over to facilitate unloading. It is suitable for short-distance transportation of various bulk materials such as sand, gravel, earth, coal, and ore. It has strong power and usually has a mechanical bucket return function. The gear plate refers to the decorative cover under the gear shift handle of the dump truck's gearbox, which is usually engraved with the vehicle's gearbox gear position.

[0003] Based on the above, the inventors found that the existing shift plate is mainly installed by bolts, and the connection method is relatively simple. Since the dump truck shakes greatly when driving, and the gear position needs to be repeatedly adjusted during driving, the shift handle often collides with the shift plate, which easily causes the shift plate to loosen. Therefore, in view of this, the existing structure is studied and improved, and a dump truck shift plate is provided, in order to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a shift plate for a dump truck. The present invention provides an anti-slip assembly, which, on the basis of a threaded connection, uses an anti-slip limiting structure to better fix the shift plate inside the mounting groove, thereby reducing the loosening problem of the shift plate. A guide assembly is provided to support and limit the anti-slip assembly, and the movement resistance is reduced by self-rotation to ensure the movement stability of the anti-slip assembly.

[0006] 2. Technical solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A shift plate for a dump truck, comprising a shift plate, a shift groove is provided in the middle of the shift plate, bolts are provided through both ends of the shift plate, anti-slip blocks are provided at both ends of the bottom surface of the shift plate, a pressure groove is provided at one end of the anti-slip block, a sliding groove is provided at the other end of the anti-slip block, a guide groove is provided at the side of the sliding groove, a return spring is provided at one end of the sliding groove, and a guide mechanism is provided at the other end of the sliding groove;

[0009] The guide mechanism comprises a sliding block, a guide rod is arranged through the middle of the sliding block, and a pair of movable balls are movably connected at both ends of the sliding block, close to the upper and lower sides.

[0010] Furthermore, the two anti-slip blocks are symmetrically arranged, and an end surface of the anti-slip block away from the pressure groove is aligned with an end surface of the baffle plate.

[0011] Furthermore, the side of the pressure groove is arranged in an arc shape, and the pressure groove is adapted to one end of the bolt.

[0012] Furthermore, the sliding block is arranged in a T-shape, and one end of the sliding block in a vertical direction is fixedly connected to the bottom surface of the baffle.

[0013] Furthermore, the sliding block is located inside the sliding groove, and the sliding block is slidably connected to the sliding groove.

[0014] Furthermore, the guide rod is fixedly connected to the guide groove, and two ends of the return spring are respectively fixedly connected to the inner surface of the guide groove and one side of the sliding block.

[0015] Furthermore, one side of the movable ball passes through the sliding block and fits into the guide groove.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] (1) This solution sets a bolt to squeeze the side of the pressure groove, so that the anti-slip block is forced to slide outward, and the outer end of the anti-slip block enters the inner side of the installation groove to form a limiting structure. At the same time, the movement of the anti-slip block compresses the reset spring. When the bolt is removed, the anti-slip block loses pressure and is reset under the action of the reset spring, thereby facilitating the removal and replacement of the baffle plate. Compared with the prior art, an anti-slip assembly is set, and the anti-slip limiting structure is used on the basis of the threaded connection to better fix the shift plate inside the installation groove, thereby reducing the loosening problem of the shift plate.

[0019] (2) By setting a guide mechanism, the sliding block cooperates with the guide rod to limit the movement of the anti-slip block, so that the anti-slip block slides along the sliding block through the sliding groove. At the same time, the movement of the anti-slip block causes the movable ball to rub against the guide groove, and the movable ball rotates, thereby reducing the moving friction between the sliding block and the sliding groove. Compared with the prior art, the guide component is set to support and limit the anti-slip component, and reduce the moving resistance by self-rotation, thereby ensuring the moving stability of the anti-slip component.

[0028] The guide mechanism 9 includes a sliding block 10 , a guide rod 11 is provided through the middle of the sliding block 10 , and a pair of movable balls 12 are movably connected to both ends of the sliding block 10 on the upper and lower sides. In order to ensure the movement stability of the anti-dropping block 4 , the guide mechanism 9 is provided.

[0029] See also Figure 1 The two anti-slip blocks 4 are symmetrically arranged, and the end face of the anti-slip block 4 away from the pressure groove 5 is aligned with the end face of one end of the baffle 1. First, put the baffle 1 into the installation groove, so that the gear handle passes through the gear groove 2, and the anti-slip block 4 is located on the inner side of the installation groove.

[0030] See also Figure 2 The side of the pressure groove 5 is arranged in an arc shape, and the pressure groove 5 is adapted to one end of the bolt 3. Then the bolt 3 is rotated to pass through the baffle plate 1 and be threadedly connected to the mounting groove, so that the position of the baffle plate 1 is fixed, and at the same time, the movement of the bolt 3 squeezes the side of the pressure groove 5.

[0031] See also Figure 3The sliding block 10 is arranged in a T shape, and one end of the sliding block 10 in the vertical direction is fixedly connected to the bottom surface of the baffle 1, and the sliding block 10 cooperates with the guide rod 11 to limit the movement of the anti-dropping block 4.

[0032] See also Figure 3 The sliding block 10 is located inside the sliding groove 6, and the sliding block 10 is slidably connected to the sliding groove 6.
