[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0025] Example:
[0026] Reference Figure 1-Figure 4As shown, a gear adjustment mechanism disclosed in the utility model includes a block 1. The top of the block 1 is open, and the top of the block 1 is open and a first through hole 11 is opened in the middle of the bottom of the block 1 along its length direction. The interior of the block 1 is hollow. A card block 3 is provided on one side of the block 1, and two slots 31 are provided between the card block 3 and the block 1. The card block 3 is clamped in the groove of the side wall of the pickup truck compartment. The cross section of the first through hole 11 consists of a rectangle and a square. The rectangle is located between the square and the card block 3. A plurality of arc grooves 14 are symmetrically arranged at the bottom of the inner wall of the block 1 along its length direction. A plurality of arc grooves 14 are located on both sides of the square through hole. The plurality of arc grooves 14 arranged at the bottom of the inner wall of the block 1 along its length direction are arranged equidistantly. The number of arc grooves 14 is 10 to 16, and the number of arc grooves 14 is an even number. In this embodiment, the number of arc grooves 14 is 12.
[0027] The cross-sectional width of the square through hole in the first through hole 11 is the same as the cross-sectional width inside the block 1 . The cross-sectional width of the square through hole in the first through hole 11 is twice the cross-sectional width of the rectangular through hole in the first through hole 11 .
[0028] The block 1 is vertically provided with an adjustment rod 12. One end of the adjustment rod 12 passes through the first through hole 11 and extends into the block 1. An insert 13 is provided at one end of the adjustment rod 12 located inside the block 1. The cross-sectional width of the insert 13 matches the cross-sectional width inside the block 1. The shape of a part of the bottom of the insert 13 matches the shape of the arc groove 14.
[0029] When the insert 13 is out of contact with the bottom of the inner wall of the block 1, the insert 13 moves freely inside the block 1. At this time, the insert 13 is completely located inside the block 1. The insert 13 enters and exits the block 1 through the square through hole in the first through hole 11.
[0030] An elastic plate 2 is arranged just above the square through hole in the first through hole 11, and one end of the elastic plate 2 is connected to the top edge of one side of the inner wall of the block 1. The other end of the elastic plate 2 is inclined downward toward the arc groove 14. The elastic plate 2 is partially located above the rectangular through hole in the first through hole 11.
[0031] In the natural state of the elastic plate 2 , the distance between the end of the elastic plate 2 close to the arc groove 14 (the lowest end of the elastic plate 2 ) and the bottom of the inner wall of the block 1 is smaller than the height of the insert 13 itself.
[0032] The implementation principle of the above embodiment is:
[0033] When in use, the block 1 is placed outside the compartment baffle to cover the top opening of the block 1. The block 3 is located in the groove of the compartment side wall. At this time, the entire gear adjustment mechanism connects the compartment and the compartment baffle. The first through hole 11 at the bottom of the block 1 is exposed. The operator inserts the insert 13 from the square through hole in the first through hole 11 and pushes the adjustment rod 12 with force. The adjustment rod 12 drives the insert 13 to move, and the insert 13 drives the elastic plate 2 to deform.
[0034] As the elastic plate 2 is deformed, the insert 13 completely enters the interior of the block 1, and the operator simultaneously moves the adjustment rod 12 to allow the insert 13 to enter between the rectangular through hole in the first through hole 11 and the compartment baffle.
[0035] When adjusting the gear position, the operator only needs to pull up the adjustment rod 12 to disengage the insert 13 from the arc groove 14, and then translate the adjustment rod 12 while keeping the height of the insert 13 unchanged, thereby moving the insert 13 inside the block 1, thereby achieving the purpose of changing the gear position.
[0036] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
