Description

A caster with support frame

【Technical field】

The utility model relates to the technical field of a caster, in particular to the technical field of a caster with a support frame.

【Background technique】

Casters generally include a connecting seat connected to the bottom of furniture or equipment, a support frame connected below the connecting seat through a first rotating shaft arranged in a vertical direction, and a roller connected to the supporting frame through a second rotating shaft arranged in a horizontal direction. . In practical applications, especially the use of casters on the air compressor or small generator set, although it brings convenience to the movement of the air compressor or small generator set, due to the air compressor or small generator set, etc. during the work process Some equipment that is easy to vibrate will shift its position through its own vibration, and the shift caused by long-term work will be large. If it is not pushed to the original position in time, it may cause the external air pipe, wire or other connecting parts to be damaged. Torn off, causing accidents, although there are casters with brakes on the market, the structure of brake pads is generally used, but there are certain disadvantages in the brake mechanism of this structure, because the friction between the brake pads and the rollers is not enough, so There is a phenomenon that the brakes are not firm, and the safety is not high.

In order to achieve the above object, the utility model proposes a caster with a support frame, including a connecting seat, a rotating shaft, a mounting seat, a roller and a supporting frame, the rotating shaft is rotatably mounted on the connecting seat, and the rotating shaft The lower end is provided with a mounting seat, and rollers are installed on the fork legs of the mounting seat. The mounting seat is provided with a support frame in front of the fork leg. Base, the base is provided with a connecting rod, the connecting rod is provided with a connecting seat, the connecting seat is connected to the upper base through the connecting rod, the front end of the adjusting screw passes through the rear connecting seat and is rotatable with the front connecting seat connected, the adjusting screw is threadedly connected with the rear connecting seat.

Preferably, the lower base, the connecting base and the upper base are all rotatably connected to the connecting rod, and the upper base is fixedly connected to the mounting base through fixing bolts.

Preferably, the rear end of the adjusting screw is provided with a cap, and the cap is provided with a through hole, and a handle is pierced in the through hole.

Preferably, a rubber pad is provided at the bottom of the lower base.

Beneficial effects of the utility model: the utility model is equipped with a support frame on the mounting base, and when the equipment used needs to be fixed at a certain position, the roller is separated from the ground through the support of the support frame, compared with the prior art , can avoid the movement of equipment caused by weak brakes, and improve safety.

The features and advantages of the utility model will be described in detail through embodiments in conjunction with the accompanying drawings.

【Description of drawings】

Fig. 1 is a structural representation of a caster with a support frame of the utility model;

Figure 2 is a schematic structural view of the support frame.

In the figure: 1-connecting seat, 2-rotating shaft, 3-mounting seat, 4-roller, 5-support frame, 51-lower base, 52-connecting rod, 53-connecting seat, 54-adjusting screw, 55-upper Base, 56-handle, 57-rubber spacer.

【Detailed ways】

Referring to Figures 1 and 2, a caster with a supporting frame of the utility model includes a connecting seat 1, a rotating shaft 2, a mounting seat 3, a roller 4 and a supporting frame 5, and the rotating shaft 2 is rotatably mounted on the connecting seat 1 , the lower end of the rotating shaft 2 is provided with a mounting seat 3, a roller 4 is installed on the fork leg of the mounting seat 3, and the mounting seat 3 is provided with a support frame 5 in front of the fork leg, and the support frame 5 includes Lower base 51, connecting rod 52, connecting seat 53, adjusting screw rod 54 and upper base 55, described base 51 is provided with connecting rod 52, described connecting rod 52 is provided with connecting seat 53, and described connecting seat 53 is connected by The rod 52 is connected with the upper base 55, the front end of the adjusting screw 54 passes through the rear connecting seat and is rotatably connected with the front connecting seat, the adjusting screw 34 is threadedly connected with the rear connecting seat, the lower base 51, the connecting seat 53 and The upper base 55 is rotatably connected with the connecting rod 52, and the upper base 55 is fixedly connected with the mounting seat 3 through a fixing bolt. The rear end of the adjusting screw 54 is provided with a cap body, and the cap body is provided with a through hole. A handle 56 is pierced through the through hole, and a rubber pad 57 is provided at the bottom of the lower base 51 .

The working process of the utility model:

The utility model is a caster with a support frame. During the working process, when the equipment used needs to be fixed at a certain position, the handle 56 is pulled to drive the adjustment screw 54 to rotate, and the adjustment screw 54 rotates to drive the rear connecting seat and the front connecting seat. Move closer, the support frame 5 is stretched to support, and the roller 4 is separated from the ground. When the equipment used needs to be moved, the handle 56 is pulled in the opposite direction to drive the adjustment screw 54 to rotate, and the rotation of the adjustment screw 54 drives the rear connecting seat and the front connecting seat. Far away from the movement, the support frame 5 is retracted, and the roller 4 returns to the ground. Compared with the prior art, it can avoid the movement of the equipment caused by weak brakes and improve safety.

The above-mentioned embodiment is an illustration of the utility model, not a limitation of the utility model, and any scheme after a simple transformation of the utility model belongs to the protection scope of the utility model.
