Description

Technical Field

[0001] The utility model relates to the technical field of chassis structures, in particular to a chassis structure of a container. Background Art

[0002] The bottom frame of a container is usually called the box bottom or skid, which is an important part of bearing the weight of the container itself and the cargo. The box bottom is a frame structure composed of components such as side rails, cross members and corner fittings. The cross members are connected to the two sides of the box bottom, and the cross members span between the cross members. This structure is very strong and can withstand the weight of the container and cargo and ensure the stability of the entire loading system. The corner fittings are located at the four corners of the box bottom and are used to fix the connection between the container and other transportation equipment (such as trailers, railway carriages, etc.). These corner fittings are usually made of steel and can withstand the tension and pressure of large containers. In the prior art, due to the fixed position of the four-corner limiters, it may not be able to adapt to containers of different sizes and types. If the container size does not match the position of the limiter, the limiter may not be able to properly fix the container, thereby reducing stability

[0003] The prior art provides a container chassis with a protective structure (Announcement No.: CN216402572U), which includes a device body and a protective device, and the protective device is arranged on the surface of the device body. The utility model greatly improves the load-bearing effect of the goods in the container through the device body, ensures the service life of the device, and cooperates with the protective device to further limit and fix the goods in the container, effectively preventing the goods from sliding in the container, causing the goods to collide and cause damage, ensuring the stability of the cargo placement process, improving the protective effect and stability of the container chassis, and facilitating use.

[0004] The above patent lacks a component for adjusting the position of the four-corner limiters. The container is fixed using a clamping plate, but the container lacks a limit in the horizontal direction of the clamping plate, and the fixing effect is poor. Therefore, we need to propose a chassis structure for the container. Utility Model Content

[0012] Preferably, a plurality of symmetrically distributed card slots are provided on the side wall of the base frame body, and the plurality of card slots are respectively card-engaged with the card blocks.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model is provided with a motor, which is turned on and drives the screw to rotate. The threaded movement between the screw and the internal threaded barrel controls the movement of the internal threaded barrel. At the same time, the internal threaded barrel drives the mounting plate to move. The mounting plate drives the hydraulic telescopic rod at the upper end to move. The hydraulic telescopic rod drives the moving plate to move in the vertical direction of the movement of the internal threaded barrel to adjust the position of the limit plate. When the mounting plate moves, the slide bar plays a limiting role to prevent the mounting plate from rotating. The limit plate slides in the slide groove and plays a limiting role on the slide bar to prevent the slide bar from separating from the base frame body. At the same time, a suction cup is provided on the upper end of the base frame body, and the suction cup absorbs the rubber plate.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 , the utility model provides a technical solution:

[0022] A container chassis structure comprises a chassis body 1, the lower end of the chassis body 1 is fixedly connected with a plurality of evenly distributed motors 2, the output shafts of the plurality of motors 2 are fixedly connected with screws 3, the outer side of the screws 3 is threadedly connected with an internally threaded tube 4, the side wall of the internally threaded tube 4 is fixedly connected with a mounting plate 5, the mounting plate 5 abuts against the side wall of the chassis body 1, the upper end of the mounting plate 5 is fixedly connected with a hydraulic telescopic rod 6, the output end of the hydraulic telescopic rod 6 is fixedly connected with a movable plate 7, the movable plate 7 abuts against the outer side of the chassis body 1, the upper end of the movable plate 7 is fixedly connected with a limiting plate 8, the side wall of the mounting plate 5 is fixedly connected with a sliding rod 9, one end of the sliding rod 9 is fixedly connected with a limiting disk 10, a sliding groove 11 is provided inside the chassis body 1, and the sliding groove 11 is slidably connected to the sliding rod 9 and the limiting disk 10 respectively.

[0023] The upper end of the chassis body 1 is provided with a plurality of suction cups 12 which are evenly distributed.

[0024] Exemplarily, the fixation by the suction cup 12 can be achieved by pressing the suction cup 12 onto the surface of the object, without the need for additional tools or equipment, and the fixation by the suction cup 12 will not damage the surface of the object: the suction cup 12 is usually made of soft materials, such as rubber or silicone, with good flexibility and tear resistance. They do not have the risk of scratching or damaging the surface of the object, and are suitable for application scenarios with high requirements on the surface of the object. They are reusable: the fixation by the suction cup 12 can be used multiple times, and only needs to be re-pressed on the surface of the object, without the need for glue, nails or other methods of fixing objects, and will not cause permanent changes or damage to the object, which is very useful in situations where objects need to be frequently fixed and moved; suitable for irregular surfaces: the fixation by the suction cup 12 can adapt to irregular or curved surfaces of objects. Due to the softness and flexibility of the suction cups 12, they can establish a seal with surfaces of various shapes and curvatures, providing a stable fixing effect.

[0025] A plurality of rubber plates 13 are respectively attached to the outer sides of the plurality of suction cups 12 , and the plurality of rubber plates 13 abut against the upper end of the bottom frame body 1 .

[0026] Exemplarily, multiple suction cups 12 fix multiple rubber plates 13 respectively. The container may be subjected to vibration and bumps during transportation. If there is no good friction between the chassis and the cargo, the cargo may slide and shake, resulting in instability and damage. The rubber plates 13 can provide additional friction to prevent the cargo from sliding and keep the container stable. At the same time, the rubber plates 13 play a buffering and shock-absorbing role on the container chassis and can absorb vibration and impact during transportation. They can reduce the external force on the cargo and reduce the risk of cargo damage.

[0027] Both ends of the plurality of rubber plates 13 are fixedly connected with elastic plates 14 , and the elastic plates 14 abut against the side wall of the bottom frame body 1 .

[0028] The opposite surfaces of the two correspondingly distributed elastic plates 14 are fixedly connected with a clamping block 15, which is hemispherical.

[0029] Exemplarily, the block 15 is hemispherical, which is convenient for installation of the block 15 . Meanwhile, the block 15 is installed on the elastic plate 14 . The elastic plate 14 has high elasticity, which facilitates adjustment of the position of the block 15 through the elastic plate 14 .

[0030] A plurality of symmetrically distributed card slots 16 are formed on the side wall of the chassis body 1 , and the plurality of card slots 16 are respectively card-engaged with the card blocks 15 .

[0031] Exemplarily, the card slot 16 is adapted to the card block 15 , and the card slot 16 receives the card block 15 to play a role in positioning the card block 15 .

[0032] Working principle: when the utility model is used, the position of the limit plate 8 is adjusted according to the size of the container, the motor 2 is turned on, the motor 2 drives the screw rod 3 to rotate, and the threaded movement between the screw rod 3 and the internal threaded tube 4 controls the internal threaded tube 4 to move, and at the same time the internal threaded tube 4 drives the mounting plate 5 to move, and the mounting plate 5 drives the hydraulic telescopic rod 6 at the upper end to move, and the hydraulic telescopic rod 6 drives the moving plate 7 to move in the vertical direction of the movement of the internal threaded tube 4 to adjust the position of the limit plate 8, and the slide bar 9 plays a limiting role when the mounting plate 5 moves to prevent the mounting plate 5 from rotating, and the limit plate 10 slides in the slide groove 11 to limit the slide bar 9 to prevent the slide bar 9 from separating from the chassis body 1, and the chassis body 1 plays a role in supporting the container, and the limit plate 8 fixes the four corners of the container;

[0033] At the same time, a suction cup 12 is provided at the upper end of the chassis body 1, and the suction cup 12 absorbs the rubber plate 13, and the rubber plate 13 supports the container and plays an anti-slip role. The elastic plate 14 drives the clamping block 15 to clamp into the inside of the clamping slot 16, and the rubber plate 13 is fixed for a second time by clamping.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
