Description

Technical Field

[0001] This utility model relates to the field of fixed accessories inside the cargo compartment of a van, specifically to a support rod used inside the cargo compartment of a van. Background Technology

[0002] A truck's cargo box refers to the part of a truck used to carry goods. Box trucks are primarily used for fully enclosed transportation of various goods, offering advantages such as maneuverability, ease of operation, high efficiency, large transport capacity, efficient use of space, safety, and reliability. Box trucks are widely used in my country's road transport and urban distribution, offering advantages such as good cargo stability and minimal impact from weather conditions. They are suitable for transporting various types of goods and are applicable to factories, supermarkets, and individuals. They are all-weather vehicles, capable of operating on intercity highways and within urban areas. After cargo is loaded into a box truck, support rods are used to secure or limit the cargo by bracing it between the two cargo box walls during transport to prevent movement or collisions.

[0003] Support bars effectively prevent cargo from shifting due to vibration or collision during transportation, ensuring its stability and safety. They are especially essential for box trucks carrying irregularly shaped or fragile items. Furthermore, using support bars allows for better utilization of cargo space, enabling more compact cargo arrangement, thereby improving transportation efficiency and reducing costs. Simultaneously, support bars effectively reduce friction and collisions between goods, preventing damage and ensuring goods arrive at their destination intact.

[0004] However, existing support rods require length adjustments based on different carriage sizes. They are often fixed with pins, and changing the extension range necessitates tool removal of the pins, which is cumbersome and doesn't provide universal compatibility across different carriages. Corresponding tracks or fixing devices need to be installed on the carriage's inner wall, limiting their application and restricting flexibility in cargo placement and size adjustment. Furthermore, the rigid connection between the existing support rods and the carriage lacks cushioning at the contact surfaces, making them prone to loosening during vehicle movement and rendering them ineffective.

[0005] Therefore, those skilled in the art urgently need a practical support rod that can solve the problems of free extension and retraction length, inflexible use, and easy loosening of the contact surface in the existing technology. Summary of the Invention

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a support rod that can freely extend and retract in length within the carriage, requires no tools for disassembly, is adjustable with buttons, can be flexibly installed, allows for easy adjustment of the installation position, and can increase the friction between the support rod and the inner wall of the carriage while maintaining the friction force unchanged during vehicle movement.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a support rod for use in the cargo compartment of a van, comprising a long outer tube, a short outer tube, an inner tube, a fixed plug, a movable plug, and a connector. The fixed plug is installed at the far end of the long outer tube and connected to one side of the cargo compartment inner wall. The movable plug is installed at the far end of the short outer tube and connected to the other side of the cargo compartment inner wall. One end of the inner tube is fixedly connected to the proximal end of the short outer tube. The connector is fitted into the proximal end of the long outer tube.

The front of the fixed plug body is nested at the end of the long outer tube, and the fixed connecting column is installed on the back of the fixed plug body and abuts against the inner wall of the compartment.

[0013] The aforementioned support rod for use inside the cargo compartment of a van has a column head at the front end of both the movable connecting column and the fixed connecting column, and the front end of the column head has a U-shaped groove.

[0014] The beneficial effects of this utility model for a support rod used in the cargo compartment of a van are as follows: By using a nested connection between a long outer tube, a short outer tube, and an inner tube, the overall length of the support rod can be adjusted at will. By using a movable plug, the length of the support rod can be adjusted while increasing the soft connection between the support rod and the inner wall of the cargo compartment, thus counteracting the shaking caused to the support rod during vehicle movement. The combined use of a movable plug spring and a movable connecting post ensures the movable plug functions elastically. By using the long and short outer tubes fitted onto the outside of the inner tube, the outer diameter of the support rod is ensured to be the same, preventing the inner tube from being completely jammed into the outer tube. By using an expansion groove and an expansion spring, the inner tube is supported on the inside of the long outer tube, further reducing the connection gap between the inner tube and the long outer tube and preventing shaking.

[0025] The movable plug is installed at the far end of the short outer tube and connected to the inner wall of the carriage on the other side. The movable plug includes a movable plug body 51, a plug body groove 52, a movable plug spring 53, and a movable connecting post 54. The movable plug body is divided into two parts with the same structure on the left and right sides. After the two parts are joined together, they form a structure with the same shape as the inner diameter of the short outer tube but slightly smaller in diameter. The movable plug body is installed at the end of the short outer tube. The plug body groove is opened in the length direction of the movable plug body. The movable plug spring is placed in the plug body groove. One end of the movable connecting post is inserted into the plug body groove and connected to the movable plug spring. The other end of the movable connecting post extends to the outside of the plug body groove and abuts against the inner wall of the carriage.

[0026] Both the movable and fixed connecting columns have column heads at their front ends, and the front ends of the column heads have U-shaped grooves 43. Using column heads with U-shaped grooves allows the fixed and movable plugs to better fit against the corrugated inner wall of the truck body. Similarly, column head plates can be used to replace the U-shaped grooves to abut against the inner wall of the truck body.

[0027] One end of the inner tube is fixedly connected to the proximal end of the short outer tube. The connector is fitted into the proximal end of the long outer tube. The other end of the inner tube passes through the connector and is inserted into the long outer tube. The connector limits the insertion length of the inner tube in the long outer tube.

[0029] The connector includes a fixed base 61, a stop plate 62, a snap fastener 63, a spring shaft, and a slot 64. The slots are evenly arranged along the length of the stop plate. The fixed base is sleeved on the end of the long outer tube. The stop plate is fixed to the outside of the inner tube using aluminum rivets 32 along the length of the inner tube. The snap fastener is rotatably mounted on the front end of the fixed base via the spring shaft. The front end of the snap fastener engages in the slot and cooperates with the slot to adjust the length of the inner tube extending out of the long outer tube. The rear of the snap fastener is set as a button structure. When the button is pressed, the front end of the snap fastener pops up, and the snap fastener separates from the slot.

[0030] Furthermore, the connector can also use a threaded tightening method.

[0031] To prevent excessive gap between the inner tube and the long outer tube from causing wobbling, the connector also includes an inner tube plug. The inner tube plug includes a plug body 65, an expansion groove 66, and an expansion spring 67. The plug body is inserted into the end of the inner tube, the expansion groove is located on the back side of the plug body, and the expansion spring is installed in the expansion groove. The outer wall of the expansion groove is in contact with the inner wall of the long outer tube.

[0032] Furthermore, to facilitate the insertion of the inner tube into the long outer tube, a slat groove 31 is provided on the outer wall of the inner tube, and the stop slat is fixed in the slat groove.
