Detailed Description

The carrier for fitment can adopt following material to make, and be not limited to following material, for example: stainless steel, aluminum alloy, plastic, rubber, profile steel, and the like.

As shown in fig. 1, in conjunction with fig. 2-5; the utility model discloses carrier for fitment includes: a frame and a plurality of sets of wheels; the multiple groups of wheels are arranged on the frame; generally, four sets of wheels are mounted on the frame, and the four sets of wheels are respectively arranged on the frame in a rectangular shape.

Each set of said wheels comprising: the bicycle comprises an axle 1 and a wheel carrier 10, wherein the axle 1 is used for being installed on the bicycle frame, and the wheel carrier 10 is sleeved on the axle 1 and can rotate around the axle; the axle is fixed on the frame and horizontally arranged, and a steering mechanism is generally arranged between the axle and the frame to facilitate the steering of the axle.

The wheel carrier 10 is of a regular triangle structure, each top end of the regular triangle structure is fixed with a support rod 2, and the top end of each support rod 2 is provided with a roller 4; one of the support rods 2 is a telescopic rod 3.

That is to say, the three support rods are respectively fixed on the wheel carrier 10 and are symmetrically arranged relative to the axle center, and the included angle between the three support rods is 120 degrees. One of the support rods adopts a telescopic structure, and the support rod is a telescopic rod.

Generally, a sleeve 30 is installed on the telescopic rod 3, and a cylindrical spring is installed in the sleeve 30; the sleeve 30 is sleeved in the telescopic rod 3 and is connected with the telescopic rod 3 through the cylindrical spring; the sleeve 30 compresses the cylindrical spring to be inserted into the telescopic rod 3, so that the length of the entire telescopic rod is reduced.

A connecting pin is further arranged between the telescopic rod 3 and the sleeve 30.

Specifically, the sleeve 30 is provided with a positioning hole; the telescopic rod 3 is provided with a jack; in a common state, in order to improve the passing speed on a smooth road surface, the insertion holes and the positioning holes are connected with each other through the connecting pins, so that the position relation between the sleeve and the telescopic rod is fixed.

Of course, under the condition that the shock absorption is needed and the door sill passes through, the connecting pin can be detached, and the whole wheel has a certain shock absorption effect. It should be noted that, when passing through the threshold, the telescopic rod enters in the direction close to the threshold; in the process of needing shock absorption, the telescopic rod deviates from the advancing direction, so that the whole frame is inclined backwards to facilitate pushing.

The utility model discloses a one of them replacement in the structural bracing piece of regular triangle of wheel carrier is the telescopic bracing piece, can make telescopic link 3 support and lean on threshold 4 at the in-process of crossing threshold 4, constantly compress the length of telescopic link 3 pushing forward the in-process to use the top of telescopic link 3 (the gyro wheel that contacts with the threshold) to rotate whole wheel carrier for the dot. (as shown in FIGS. 2-5)

Because the weight of frame concentrates on the telescopic link in the rotation process, the telescopic link is by furthest's compression, and in the rotation process, whole wheel carrier only need slightly rise can pass threshold 4, avoids the idle work that the axletree rose too much and bring, and indirect reduction the thrust in the use, messenger's carrier can be better pass threshold 4.

In the present embodiment of the carrier for decoration, a protective sleeve 40 for covering the roller 4 is disposed at the top end of the supporting rod 2, and the roller 4 is mounted on the supporting rod 2 through the protective sleeve 40; a semicircular groove is formed in the protective sleeve 40, and the roller 4 is installed in the groove.

The semicircular groove prevents foreign matters from being clamped into the roller and can also directly collide with obstacles in the process of rotating the roller and crossing the doorsill. In addition, the semicircular grooves can enable the whole wheel frame to well abut against obstacles in the rotating process, and sufficient friction force is provided to facilitate the rotation of the wheel frame.

The protective sleeve is typically made of wear resistant plastic or rubber.

In the present embodiment of the present invention, preferably, the wheel frame 10 is provided with a scale 11. The scale is generally used for marking the ground clearance of the whole wheel carrier so as to conveniently judge whether the height of the supporting rod is enough to cross the threshold. The height of each supporting rod can be adjusted or the supporting rods with different heights can be replaced, so that the requirements of crossing doorsills with different heights can be met.

Further, the outer side of the wheel frame 10 is covered with a rubber layer. The wheel frame is prevented from being worn or damaged in the process of crossing the obstacle or the threshold.

In addition, the outside of bracing piece 2 also can be provided with crashproof protective sheath.

The carrier for decoration of the present embodiment, wherein the ratio of the minimum length of the telescopic rod 3 to the length of the support rod 2 is 0.45-0.53: 1. so as to ensure that the vertical direction of the axle is kept from generating excessive displacement to the maximum extent in the process of rotating the whole wheel carrier.

Additionally, the utility model discloses a carrier manufacturing cost is not high for the fitment, and structural design is compact, and the structure is ingenious, and finished product quality is stable, and is aesthetic in appearance, uses and maintains the convenience, is applicable to the various places that need stride across barrier and heavy load.
