DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 A lower support plate for trailer suspension axle accessories, comprising a transverse plate 1, a plurality of positioning holes 2 are provided at both front and rear ends of the transverse plate 1, the positioning holes 2 are used to connect the transverse plate 1 and the trailer frame, the front and rear ends of the transverse plate 1 are both extended to both sides with extension plates, the lower side wall of the transverse plate 1 is symmetrically fixedly connected with a connecting plate 1 3 and a connecting plate 2 4, the connecting plate 1 3 and the connecting plate 2 4 are vertically arranged, and the connecting plate 1 3 and the connecting plate 2 4 are respectively located at the front and rear ends of the transverse plate 1, and the ends of the connecting plate 1 3 and the connecting plate 2 4 are respectively fixedly connected with the connecting plates 1 and 2 4 located at the lower side wall of the transverse plate 1. The positioning plates 15 and 26 on the side are arranged parallel to the horizontal plate 1. A plurality of positioning holes 27 are arranged on the positioning plates 15 and 26. The positioning holes 27 are used to connect the positioning plates 15 and 26 with the corresponding suspension system. Rubber washers are arranged on the outer sides of the positioning holes 2 and 27. The rubber washers have a certain protective effect on the positioning holes 12 and 27, reducing the wear of the positioning holes 12 and 27. The width of the positioning plates 15 and 26 is less than the width of the horizontal plate 1.

[0021] Two slots 18 are symmetrically provided on the extension plates on both sides of the front end of the horizontal plate 1. The slots 18 are arranged horizontally. The two slots 18 penetrate the corresponding extension plates front and back. Two slots 29 corresponding to the slots 18 are provided on the upper side wall of the positioning plate 5. The two slots 29 penetrate the positioning plate 5 front and back and are respectively close to the left and right ends of the positioning plate 5. Two slots 3 10 are symmetrically provided on the extension plates on both sides of the rear end of the horizontal plate 1. The slots 3 10 are arranged horizontally. The two slots 3 10 penetrate the corresponding extension plates front and back. Two slots 4 11 corresponding to the slots 3 10 are provided on the upper side wall of the positioning plate 2 6. The two slots 4 11 are It penetrates the positioning plate 2 6 front and back and is close to the left and right ends of the positioning plate 2 6 respectively. The slot 1 8 and the corresponding slot 2 9 are slidably inserted with an insert plate 12, and the slot three 10 and the corresponding slot four 11 are slidably inserted with an insert plate 2 13. The distance between the slot 1 8, the slot three 10 and the axis of the horizontal plate 1 is greater than the distance between the slot two 9, the slot four 11 and the axis of the horizontal plate 1. The axis is the long symmetry axis of the horizontal plate 1. Therefore, the insert plate 12 and the insert plate 2 13 are tilted so that the insert plate 12 and the insert plate 2 13 are located on the outside of the positioning hole 1 2 and the positioning hole 2 7 to avoid interference with the fastening bolts in the positioning hole 1 2 and the positioning hole 2 7.

[0022] In order to prevent the plug plate 12 and the plug plate 2 13 from falling, the front and rear side walls of the positioning plate 1 5 and the front and rear side walls of the positioning plate 2 6 are provided with limit plates 14, and bolts 15 are provided on the limit plates 14. The positioning plate 1 5 and the positioning plate 2 6 are fastened to the corresponding limit plates 14 by bolts 15. The limit plates 14 limit the two ends of the plug plate 12 and the plug plate 2 13 to prevent the plug plate 12 and the plug plate 2 13 from sliding out.

[0023] There is a gap between the plug plate 12 and the slot 1 8 and the slot 2 9, and there is a gap between the plug plate 2 13 and the slot 3 10 and the slot 4 11. Therefore, the plug plate 12 and the plug plate 2 13 are prone to vibration during the driving of the trailer. In order to reduce this vibration, the left and right side walls of the positioning plate 1 5 and the positioning plate 2 6 are fixedly provided with support plates 16, and the inner side of the support plate 16 is fixedly provided with a plurality of pressure plates, and a spring 17 is fixedly connected between the pressure plate and the support plate 16. The spring 17 squeezes the pressure plate against the outer wall of the corresponding plug plate 12 and the plug plate 2 13 to reduce the vibration of the plug plate 12 and the plug plate 2 13. The ends of the plug plate 12 and the plug plate 2 13 are fixedly connected with push-pull handles 20 to facilitate pushing and pulling the plug plate 12 and the plug plate 2 13.

[0024] A connecting rod 18 and a connecting rod 2 19 are fixedly connected between the connecting plate 1 3 and the connecting plate 2 4. The connecting rod 18 and the connecting rod 2 19 are respectively located on both sides of the connecting plate 1 3 and the connecting plate 2 4, and are in contact with the lower side wall of the cross plate 1, thereby improving the bending resistance of the cross plate 1. The plug plate 12 and the plug plate 2 13 are beneficial to improving the connection strength between the cross plate 1 and the positioning plate 1 5 and the positioning plate 2 6, and are detachable at the same time. After the plug plate 12 and the plug plate 2 13 are disassembled, the exposure range of the positioning hole 1 2 and the positioning hole 2 7 is increased, thereby improving the loading and unloading efficiency of the lower support plate or the suspension system.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
