Description

Technical Field

[0001] The utility model relates to the technical field of vehicle supporting devices, in particular to a high-strength supporting structure for a supporting device. Background Art

[0002] Vehicle connection mainly refers to the connection between a trailer and a tractor head when the tractor tows the trailer. The supporting device is an essential device when the trailer is connected to the tractor head. The trailer is lifted by the supporting device, and then the position of the tractor head is adjusted. After alignment, the supporting device is controlled to release force so that the trailer falls on the tractor head. Similarly, the supporting device is also an essential device during the decoupling process.

[0003] In an existing supporting device, a contact base is rotatably connected to the end of a telescopic support rod. When contacting the ground, the contact base automatically rotates to fit the ground to reach the best contact angle, ensuring good support for the vehicle.

[0004] The above prior art solution has the following defects: A single fixed column is often fixedly connected at the hinge joint between the telescopic support rods as the hinge point. The fixed column is cylindrical, and the contact base is hinged and installed on the fixed column. The single fixed column bears all the loads from the vehicle. During long-term use, it is prone to deformation, affecting the reliability of the rotational connection. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-strength supporting structure for a supporting device.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] It includes a telescopic support rod and a contact base. An installation plate with bolt holes is extended on the outer wall of the top end of the support rod. At the bottom end of the telescopic column, a pair of fixed plates are extended at intervals. The contact base includes a fixed column fixedly connecting the two fixed plates. The fixed column is hingedly provided with a pair of rotating plates. The rotating plates are respectively attached to the two fixed plates. An anti-slip plate is fixedly installed at the bottom end of the rotating plate. An arc-shaped support plate penetrating the anti-slip plate is fixedly provided on one side of the fixed plate close to the anti-slip plate. The anti-slip plate is provided with an arc-shaped groove matching the arc-shaped support plate.

[0008] By adopting the above technical solution, when the support rod plays a supporting role and transfers the vehicle load to the contact base, part of the load is transferred to the ground through the fixed column, the rotating plate and the anti-slip plate, and the other part of the load is transferred to the ground through the fixed plate, the arc-shaped support plate, the arc-shaped groove and the anti-slip plate, making the load transfer distribution between the support rod and the contact base more uniform and reasonable, avoiding the long-term load transfer of a single fixed plate and rotating plate, causing local deformation. The arc-shaped support plate and the arc-shaped groove cooperate with each other. On the one hand, it can ensure the normal rotation of the rotating plate, and on the other hand, it can disperse the load borne by the fixed column. The contact area between the arc-shaped support plate with a certain arc and the arc-shaped groove is larger than the plane contact, and its contact area is effectively increased, which can further disperse the load, reduce the pressure on the arc-shaped support plate, and is more firm and not easily damaged, which is beneficial to long-term support. The contact base can support for a long time without easily deforming.

[0009] Further, the support rod includes a positioning part and a telescopic part. The positioning part is fixedly connected to the mounting plate. The telescopic part is nested in the positioning part and is slidably arranged. The telescopic part is fixedly connected to the fixed plate. A driving screw is rotatably arranged at the center of the positioning part. The driving screw is threadedly connected to the telescopic part. A rotating rod is penetratively arranged on the outer wall of the positioning part. A first bevel gear is fixedly sleeved at one end of the driving screw. A second bevel gear meshing with the first bevel gear is sleeved at the end of the rotating rod penetrating into the positioning part. A driving device is installed at the end of the rotating rod penetrating out of the outer wall of the positioning part.

[0010] By adopting the above technical solution, during use, the driving device drives the rotating rod to rotate. The driving screw rotates through the meshing of the first bevel gear and the second bevel gear. When the driving screw rotates, the telescopic part with threaded fit will rise or fall according to the rotation direction of the driving screw, achieving the effect of controlling the free telescoping of the telescopic part.

[0011] Further, the driving device includes a first connecting column that is vertically and penetratively arranged through the rotating rod in a fitting manner. U-shaped plates connecting the first connecting column are clamped on both sides of the rotating rod. A lengthened handle is fixedly installed on the outer wall of the U-shaped plate. A handle sleeve is rotatably arranged at the end of the lengthened handle. A handle clip for placing the lengthened handle is installed on the outer wall of the positioning part. The handle clip is made of elastic plastic, and a handle groove matching the lengthened handle is opened on its outer wall.

[0012] By adopting the above technical solution, when the lengthened handle is not in use, it can be folded and embedded in the handle groove for proper storage, effectively avoiding the lengthened handle being exposed to the outside and being damaged by random shaking and impact during driving. When in use, take out the lengthened handle and then unfold it, and rotate it to drive the rotating rod to rotate clockwise or counterclockwise, achieving the effect of controlling the telescoping of the support rod.

[0013] Furthermore, paired first reinforcing columns are connected to each other on both sides of the fixed plate, a single second reinforcing column is connected to the center of the rotating plate and is located at the exact middle position between the two side reinforcing columns, and a balance spring is connected between the first reinforcing column and the second reinforcing column.

[0014] By adopting the above technical solution, the first reinforcing column can effectively strengthen the strength of the fixed plate, the second reinforcing column can effectively strengthen the connection strength of the rotating plate, and the balance spring pulls the first reinforcing columns on both sides respectively, ensuring that the non-slip plate in contact with the ground is tightened and maintained at a horizontal angle in the natural state. When contacting the ground, the balance spring can adaptively expand and contract according to the angle of fitting the ground. While not affecting the rotation of the contact base to fit the ground, in the natural state, it tightens the contact base to keep the contact base horizontal for easy lowering, and at the same time can prevent it from shaking under force and causing collision damage, having good structural stability.

[0015] In summary, the beneficial technical effects of the present utility model are as follows:

[0016] 1. The arc-shaped support plate and the arc-shaped groove are adopted, and the arc-shaped support plate and the arc-shaped groove cooperate with each other, thereby producing a more firm and not easily damaged effect, which is beneficial for long-term support, and the contact base can support for a long time without easily deforming;

[0017] 2. The positioning part, the telescopic part, the driving screw, the first bevel gear and the second bevel gear are adopted, thereby producing the effect of achieving the free expansion and contraction of the telescopic part;

[0018] 3. The first reinforcing column, the second reinforcing column and the balance spring are adopted, thereby producing the effect of effectively strengthening the strength of the fixed plate and the rotating plate, while tightening the contact base in the natural state to keep the contact base horizontal for easy lowering, and at the same time can prevent it from shaking under force and causing collision damage, maintaining good structural stability.

The anti-slip plates 22 are provided with arc-shaped grooves 24 matching the arc-shaped support plates 23. When the support rod 1 plays a supporting role and transfers the vehicle load to the contact base 2, a part of the load is transferred to the ground through the routes of the fixed columns 41, the rotating plates 21, and the anti-slip plates 22, and another part of the load is transferred to the ground through the routes of the fixed plates 4, the arc-shaped support plates 23, the arc-shaped grooves 24, and the anti-slip plates 22, making the load transfer distribution between the support rod 1 and the contact base 2 more uniform and reasonable, avoiding the long-term load transfer between a single fixed plate 4 and the rotating plate 21, which may cause local deformation. The arc-shaped support plates 23 and the arc-shaped grooves 24 cooperate with each other. On the one hand, it can ensure the normal rotation of the rotating plates 21. On the other hand, it can disperse the load borne by the fixed columns 41.

A driving device 5 is installed at the end of the rotating rod 14 penetrating through the outer wall of the positioning part 11. During use, the driving device 5 drives the rotating rod 14 to rotate. The driving screw 13 rotates through the meshing of the first bevel gear 15 and the second bevel gear 16. When the driving screw 13 rotates, the telescopic part 12 with a threaded fit will rise or fall according to the rotation direction of the driving screw 13, achieving the effect of controlling the free telescoping of the telescopic part 12.

[0029] The driving device 5 includes a first connecting column 52 movably arranged through the rotating rod 14 vertically.
