DETAILED DESCRIPTION

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0020] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the implementation of the present invention, for the sake of convenience, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Figure 1-Figure 3 The schematic diagram of the entire structure of the bottom plate fixing structure of a camping trailer of the utility model is shown in FIG. Figure 1-Figure 3 The camping trailer floor fixing structure of the present embodiment includes a floor main frame 10, which includes a rear U-shaped frame 20 and a front U-shaped frame 30, and high-strength rotating shafts 40 are connected to both ends of the rear U-shaped frame 20 and the front U-shaped frame 30. The connection part of the rear U-shaped frame 20 and the front U-shaped frame 30 is also provided with a positioning reinforcement component 50 for fixing the rear U-shaped frame 20 and the front U-shaped frame 30 straight. A first cross beam is fixed to the inner middle section of the rear U-shaped frame 20. 201, a plurality of support rail beams 202 are fixed between one side of the first cross beam 201 and the inner outer end of the rear U-shaped frame 20, a second cross beam 301 is fixed to the inner middle section of the front U-shaped frame 30, a plurality of support longitudinal beams 302 are fixed between one side of the second cross beam 301 and the inner outer end of the front U-shaped frame 30, and the outer end of the rear U-shaped frame 20 has a plurality of support rods 60 that slide and retract on the inner side and one end of the support rail beam 202, and a connecting rod 601 is fixed to the outer end of the support rod 60.

[0023] The positioning reinforcement assembly 50 includes a positioning seat 1 501 fixed to the inner side of the front U-shaped frame 30, a support bolt 502 hinged at one end to the inner side of the positioning seat 1 501, a positioning hole 502a provided at the outer end of the support bolt 502, a positioning seat 2 503 fixed to the inner side of the rear U-shaped frame 20, and a locking bolt 504 threadedly connected and penetrated through the positioning seat 2 503 and the positioning hole 502a. In this embodiment, the rear U-shaped frame 20 and the front U-shaped frame 30 are secured by the high-strength rotating shaft 40. When not in use, it can be folded in half, thereby greatly reducing the space occupied by the bottom plate main frame 10 and the entire bottom plate device, which is convenient for carrying when camping; at the same time, when the rear U-shaped frame 20 and the front U-shaped frame 30 are unfolded, the support bolt 502 connected to the positioning seat 1 501 can be rotated to the inside of the positioning seat 2 503, and the connection is fixed by tightening the locking bolt 504, so that the entire bottom plate main frame 10 and the bottom plate device form an unfolded and firm carrier with the characteristics of good stability and convenient operation.

[0024] Auxiliary pull rods 602 that are telescopic to the outer ends of the rear U-shaped frame 20 are also fixed at both ends of the connecting rod 601. The outer ends of the rear U-shaped frame 20 respectively have avoidance holes 20a corresponding to the supporting pull rods 60 and positioning sliding holes 20b corresponding to the auxiliary pull rods 602. When the trailer floor needs to carry larger or more objects, the connecting rod 601 can be directly pulled to make multiple supporting pull rods 60 slide out from the inside of the supporting rail beam 202, and the stretching stroke can be adjusted according to actual needs. When not in use, they can be directly retracted and stored to avoid taking up space. The load-bearing surface and space can be expanded according to the actual size of the object and the amount of things, further improving the flexibility and practicality of the trailer floor.

[0025] It can be understood that the cooperation with the auxiliary pull rod 602 can further increase the effective support area of ​​the bearing surface of the telescopic structure, making it more stable when placing objects.

[0026] Furthermore, support suspensions 70 are fixed to the opposite sides of the first crossbeam 201 and the second crossbeam 301 respectively and their ends are close to each other. The setting of the support suspensions 70 can further increase the effective bearing surface of the base plate, prevent a large gap in the middle of the base plate, and will not affect the normal operation of the positioning reinforcement assembly 50.

[0027] Furthermore, a towing connector 80 is fixed to the outer end of the front U-shaped frame 30. It can be understood that the towing connector 80 can be conveniently connected to a towing member such as a towing rope of a trailer, thereby improving its practicality.

[0028] Furthermore, wheel mounting parts 90 are respectively fixed to both ends of the outer walls of the rear U-shaped frame 20 and the front U-shaped frame 30. It can be understood that wheels are important accessories for the trailer bed to move, so the wheels can be conveniently positioned and installed through the wheel mounting parts 90. Of course, the wheel mounting parts 90 in this embodiment are not limited to specific structures and functions.

[0029] In summary, the camping trailer floor fixing structure of the present embodiment, when in use, can be folded and stowed between the rear U-shaped frame 20 and the front U-shaped frame 30 when not in use through the provision of a high-strength rotating shaft 40, thereby reducing the space occupied by the floor main frame 10 and the entire floor device, which is convenient for camping and carrying; at the same time, when the rear U-shaped frame 20 and the front U-shaped frame 30 are unfolded, the support bolt 502 connected to the positioning seat 1 501 can be rotated to the inner side of the positioning seat 2 503, and connected and fixed by tightening the locking bolt 504, so that the entire floor main frame 10 and the floor device form an unfolded and firm carrier.

[0030] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
