Description

Rear goods shelf

Technical Field

The invention belongs to the technical field of motorcycles, and particularly relates to a rear storage rack.

Background

The rear shelf is generally mounted at the rear of the motorcycle frame to carry the cargo. When the motorcycle runs on a rugged mountain road, the motorcycle greatly shakes in the running process, although goods are fixed on the rear goods shelf, the goods slowly shift on the rear goods shelf due to shaking, and finally the goods fall off due to unstable fixation; meanwhile, the existing rear goods shelf usually adopts an integral large goods shelf structure, although the carrying capacity is large, the integral rigidity is poor, potential safety hazards exist, the structure is complex, the assembly is difficult, and the connection with a tail box is inconvenient.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a rear goods shelf which can stably fix goods by turning over and can enhance the stability of the rear goods shelf during loading.

In order to solve the technical problems, the basic scheme of the invention is as follows:

the rear goods shelf comprises a support frame arranged at the tail of the car body and a turnover frame arranged on the upper portion of the support frame, wherein the support frame and the turnover frame are formed by longitudinally and transversely arranged support tubes in a fixed connection mode, a torsion spring penetrates through one support tube on the support frame, the torsion spring is fixedly connected between the support frame and the turnover frame, and the support tubes in the turnover frame and the support tubes in the support frame are mutually staggered in vertical projection.

The working principle and the advantages of the invention are as follows:

1. through the cross arrangement of the supporting tubes in the turnover frame and the supporting tubes in the supporting frame, the contact area between the supporting tubes and goods is increased, the gravity center of the rear goods shelf is deviated to the inner side of the center of the supporting frame, and the structural stability of the rear goods shelf when the goods are pulled is improved.

2. Through setting up the torsional spring on the support frame, place the goods on the upper portion of support frame, the pulling turns over the elasticity that the book frame passes through the torsional spring and can fasten the goods on the support frame, prevents that the goods from breaking away from back goods shelves because of the shake.

Furthermore, a supporting tube at one end of the turnover frame, which is far away from the torsion spring, is tilted upwards to form a lifting handle; the supporting tubes on the turnover frame are arranged to be tilted upwards, so that a user can easily pull the turnover frame with hands when using the turnover frame, and the turnover frame is more convenient to use.

Furthermore, a vertical rod is fixedly connected below the support frame, the vertical rod is rotatably connected with a transverse rotating shaft, and fan-shaped blades rotating along with the movement of the vehicle body are mounted on the rotating shaft; the hinge is connected with the stay cord between the pivot and the one end of turning over the book frame and keeping away from the torsional spring, and pole setting mid-mounting has the jam plate, and it has the lockhole that supplies the stay cord to pass to open on the jam plate, and the interval is installed a plurality of pawls on the stay cord, the unidirectional lockhole that passes on the jam plate of pawl when the stay cord is taut.

Through the automobile body motion process, thereby the fan-shaped blade of wind-force blowing of production rotates and drives the pivot and rotate along the pole setting, thereby the pivot rotates and twines the stay cord in the pivot, because install the pawl on the stay cord, the stay cord is taut back, and the stay cord can prevent that the flip from shaking the phenomenon that makes the goods drop through rugged road surface and taking place, through utilizing the automobile body motion and taut with the stay cord automatically to make the goods steadily fix on back goods shelves.

Furthermore, one end of the pull rope is fixedly connected with a circular ring which can slide on the turnover frame; through setting up the ring, can adapt to the not back that the goods of equidimension are placed on the support frame, the stay cord is at taut in-process, and the contact jaw that rotates the power stay cord that provides according to the pivot is owing to the setting of ring at the folding frame, and the stay cord can slide on the folding frame and fix the goods of not unidimensional.

Further, an axial joint seam for winding the pull rope is arranged on the rotating shaft; the stay cord can avoid the stay cord to take place to slide when twining in the pivot through the kerf when twining in the pivot, and takes place to turn over the phenomenon that the folding frame is fixed unstably.

Furthermore, the lock plate also comprises a pull ring for adjusting the aperture of the lock hole, and the pull ring is arranged on the side surface of the lock plate; the aperture size of the lock hole of the lock plate is adjusted through the pull ring, and the pawl on the pull rope can be opened through the lock hole by pulling the pull ring, so that the turnover frame is opened.

Furthermore, sponge strips are arranged at the bottoms of the supporting tubes in the turnover frame; through setting up the sponge strip can prevent to turn over when rolling over the frame and compressing tightly the goods, produce fold seal or even broken goods and influence the use of goods to the goods.
