Description

Technical Field

[0001] The present application relates to the technical field of side-pull box support, and in particular to an auxiliary support leg for a side-pull box. Background Art

[0002] An OB vehicle is a vehicle that carries TV broadcasting equipment and has functions such as video recording and editing, and is used for live broadcasting. The side pull box is one of the important structures in the design of an OB vehicle to increase space and improve comfort. The OB vehicle provides great convenience for the production and live broadcast of TV programs through its highly integrated, multifunctional and highly mobile characteristics. The side pull box is a design method for the box structure of an OB vehicle, especially large OB vehicles often use a side pull box structure. This structure can greatly increase the usable space in the OB vehicle and improve the comfort in the OB vehicle. When in use, the side pull boxes on both sides of the original vehicle body need to be pulled apart for use.

[0003] The side pull box of a large broadcast vehicle is relatively wide. When the side pull box is pulled out too deep, it may sink because it cannot be effectively supported during the pulling process. After long-term use, it will cause deformation and affect its service life. Utility Model Content

[0020] Furthermore, the installation of the elastic member can push the limit block to pop out through the elastic deformation force of the elastic member, so that it can always be in contact with the carrying plate, thereby preventing the carrying plate from swinging.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

A bearing plate 3 is hinged in each of the two slots 2. Two telescopic rods 4 are slidably inserted into the inner walls of the two slots 2.

By installing the telescopic rod 4, the bearing plate 3 can be provided with supporting force to prevent the bearing plate 3 from sinking due to a large weight. By installing the support rod 7 and cooperating with the multiple auxiliary plates 8, the contact area with the soil can be increased when the bearing plate 3 is placed on the soil ground, so that the bearing plate 3 can be placed on a relatively soft ground, thereby improving the overall practicality.

[0034] See also Figure 1 , Figure 4 and Figure 5 The inner walls of the two recovery grooves 5 are fixedly connected to the limit rods 9, and the outer surfaces of the two limit rods 9 are slidably connected to the limit sleeves 10. The outer surfaces of the two limit sleeves 10 are hinged with fixed plates 11, and the two fixed plates 11 are hinged to the hydraulic rods 6 close to them. Installing the fixed plates 11 can support the hydraulic rods 6 so that the hydraulic rods 6 can maintain a stable vertical state. The outer surfaces of the two limit rods 9 are provided with card grooves 12, and the insides of the two card grooves 12 are slidably connected with a group of blocks 13, each group of blocks 13 is in contact with the limit sleeves 10 close to it, and each group of blocks 13 is fixedly connected with springs 14.

[0035] See also Figure 4 , Figure 5 and Figure 6, the outer surfaces of the two support rods 7 are provided with threaded grooves 15, and the lower parts of the two bearing plates 3 are provided with threaded tubes 16, and the two threaded tubes 16 are threadedly connected to the threaded grooves 15 adjacent to them, and the bottom surfaces of the two threaded tubes 16 are fixedly connected with rubber pads 17, and the installation of the threaded tubes 16 and the rubber pads 17 can facilitate the support of the bearing plate 3 on the flat bottom surface, and can achieve the effect of shock absorption, and the upper surfaces of the two bearing plates 3 are installed with rubber plates 18, and the two rubber plates 18 are symmetrical, and the installation of the rubber plates 18 can protect the bearing plates 3, and avoid friction between the bearing plates 3 and the objects carried, which affects the use of the bearing plates 3, and the inner bottom walls of the two notches 2 are provided with limit grooves 19, and the two limit grooves 19 are provided with the inner bottom walls of the two notches 2. The interior of the positioning groove 19 is slidably connected to the limiting block 20, and the two limiting blocks 20 are in contact with the adjacent load-bearing plate 3. The bottom ends of the two limiting blocks 20 are fixedly connected with elastic members 21, and the other ends of the two elastic members 21 are fixedly connected to the adjacent limiting grooves 19. The cooperation of the installed limiting blocks 20 and the elastic members 21 can limit the load-bearing plate 3 to prevent the load-bearing plate 3 from swinging when the load-bearing plate 3 is installed. The two springs 14 are in a reset state, and the two elastic members 21 are in a reset state.

[0036] See also Figure 1 , Figure 4 and Figure 5 Two swing grooves 22 are provided on the front of the vehicle body 1, and the two swing grooves 22 are connected to the limit grooves 19 adjacent to them. The front of the two limit blocks 20 are fixedly connected with swing plates 23, and the two swing plates 23 are slidably connected to the limit grooves 19 adjacent to them. The cooperation of installing the swing plates 23 and the swing grooves 22 can be on the recovery load-bearing plate 3, and the swing plates 23 are pulled down to separate the limit blocks 20 from the load-bearing plate 3, so that the limit on the load-bearing plate 3 can be released, so that the load-bearing plate 3 can return to the slot 2.

[0037] An auxiliary support leg of a side-pull box in the present embodiment can provide support for the load-bearing plate by installing a telescopic rod, thereby preventing the load-bearing plate from sinking due to a large weight. By installing the support rod and cooperating with multiple auxiliary plates, the contact area with the soil can be increased when the load-bearing plate is placed on the soil ground, so that the load-bearing plate can be placed on a relatively soft ground, thereby improving the overall practicality.

[0038] The working principle of the above embodiment is as follows: when the load-bearing plates 3 are used to support an object, the two load-bearing plates 3 are swung to make the two load-bearing plates 3 parallel to each other. At this time, the elastic deformation of the elastic member 21 can push the limit block 20 to pop out and contact the load-bearing plates 3, so that it can limit the load-bearing plates 3 to prevent the load-bearing plates 3 from swinging. When the two load-bearing plates 3 are unfolded, the telescopic rod 4 can share the weight of the load-bearing plates 3 to prevent the load-bearing plates 3 from sinking due to a large weight. Subsequently, the two hydraulic rods 6 are swung to make the two hydraulic rods 6 in a vertical state, and the rubber pad 17 is pushed by the hydraulic rod 6 to contact the ground to support the load-bearing plates 3. After the hydraulic rod 6 is in a vertical state, the sliding sleeve can slide into place on the fixed rod. At this time, the elastic deformation force of the spring 14 can push the stopper 13 to pop out, so that the stopper 13 can cooperate with the sliding rod sleeve to limit the fixed plate 11, so that the fixed plate 11 can support the hydraulic rod 6 to prevent the hydraulic rod 6 from swinging. When support is required on soft soil, the threaded cylinder 16 is removed by rotating so that the hydraulic rod 6 pushes the support rod 7 to be inserted into the soil. At this time, multiple auxiliary plates 8 are unfolded to make the multiple auxiliary plates 8 contact with the ground, thereby increasing the contact area with the soil and placing the bearing plate 3 on relatively soft ground, thereby improving the overall practicality.
