Description

Cargo container door buffer block

Technical Field

The utility model belongs to the technical field of the goods chamber door annex, concretely relates to goods chamber door buffer block.

Background

The cargo box door buffer block is fixed on the cargo box door inner plate and the cargo box side plate through the self-reverse buckling type clamping groove and used for limiting the closing of the tail door. At present, the buffer blocks of the container door are generally bilaterally symmetrical parts and are generally formed by injection molding of an EPDM material. But bilateral symmetry's goods chamber door buffer block because the upper and lower installation characteristic is unanimous, can improve the risk of misloading by a wide margin, and the convenience of installation is relatively poor.

Therefore, there is a need to develop a new cargo box door bumper.

Disclosure of Invention

The utility model aims at providing a goods chamber door buffer block, it can satisfy the left and right sides installation simultaneously and use, has reduced mould design and manufacturing cost, has reduced about the wrong dress risk.

The cargo box door buffer block of the utility model is of a self-symmetrical structure and comprises a buffer part and a clamping head vertically connected with the buffer part, wherein the clamping head is provided with a hole extending along the length direction; and an anti-drop groove is arranged at the joint between the buffer part and the clamping joint.

The front end fillet of buffering portion produces the installation and interferes when avoiding facing the panel beating step, and the workman of being convenient for is rotatory to be installed, satisfies workman assembly requirement.

Further, the section of the anti-falling groove is a circular arc.

Further, the radius of the circular arc is 1 mm-2 mm.

The utility model has the advantages of it is following:

(1) the container door buffer block is symmetrical about the central line position, can satisfy the installation of left and right sides simultaneously and use, has reduced mould design and manufacturing cost, has reduced about the wrong dress risk.

(2) The front end part of the cargo box door buffer block is made into a round angle, so that installation interference generated when the cargo box door buffer block faces a metal plate step is avoided, workers can conveniently rotate and install the cargo box door buffer block, and the assembly requirements of the workers are met.

(3) The middle part of the clamping joint is hollowed out, so that the weight of a vehicle body is effectively reduced, the light weight of parts is realized, the shape compression is facilitated, the material release is realized, the installation is convenient, the failure is prevented, and the material cost is saved.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, the cargo box door buffer block is of a self-symmetric structure, namely, the cargo box door buffer block is symmetric by taking a dotted line in fig. 1 as a central line, and can be installed and used on the left side and the right side at the same time, so that the mold design and manufacturing cost are reduced, and the left-right wrong installation risk is reduced.

As shown in fig. 1 and 2, the cargo box door buffer block comprises a buffer part 1 and a clamping joint 2 vertically connected with the buffer part 1, a hole 3 extending along the length direction of the clamping joint 2 is formed in the clamping joint, namely the clamping joint 2 adopts a hollow structure, the hollow structure effectively reduces the weight of a vehicle body, realizes light weight of parts, and is beneficial to shape compression, material release, convenient installation, failure prevention and material cost saving.

As shown in fig. 2, a separation-preventing groove 5 is formed at the joint between the buffer portion 1 and the card connector 2 to prevent separation. In this embodiment, the section of the anti-drop groove 5 is an arc, and the radius of the arc is 1mm to 2 mm.

As shown in fig. 1, 2 and 4, the front end of the buffer part 1 is rounded 4, so that the buffer part can be suitable for planar hole site clamping, can also be suitable for clamping with reinforcing ribs or step surfaces at the periphery, can avoid blocking caused by interference with a metal plate during rotation, and is convenient to install.

As shown in fig. 3 and 4, the cargo door bumper is designed to have a sufficient relief space for the cargo door bumper to deform when installed by adding a 0.5mm clearance at the mating clearance position 6.
