Description

Brake mechanism of shallow

Technical Field

The invention relates to the field of carts, in particular to a brake mechanism of a cart.

Background

Carts are often used in everyday life, such as movable hospital beds in hospitals, etc. The bottom of the existing cart is generally provided with corresponding universal rollers, and the rollers are required to be braked in order to prevent the cart from displacing after the cart is pushed to a destination. Thereby traditional braking mode makes the lower extreme of screw rod support ground through rotatory screw rod and realizes the brake, and above-mentioned mode need squat down and rotate the screw rod repeatedly, consuming time and wasting power.

Disclosure of Invention

In summary, in order to overcome the defects of the prior art, the technical problem to be solved by the invention is to provide a brake mechanism of a cart.

The technical scheme for solving the technical problems is as follows: a brake mechanism of a cart comprises a support rod, a rotating shaft and a roller; the upper end of the supporting rod is fixedly connected with the corresponding position of the cart, and the lower end of the supporting rod is fixedly provided with a base; the rotating shaft can rotatably penetrate through the base, and the rollers are respectively fixed at two ends of the rotating shaft; the trolley is characterized in that a sliding block is sleeved on the supporting rod and can slide up and down, and brake rods which slide down and clamp the idler wheels to prevent the idler wheels from rolling to brake the trolley are fixed at two ends of the sliding block respectively.

On the basis of the technical scheme, the invention can be further improved as follows:

furthermore, a brake disc is fixed on one side of the roller wheel, which is close to the rotating shaft; the brake rod is horizontally arranged, the end part of the brake rod vertically corresponds to the brake disc, the brake disc is clamped or loosened in the process that the sliding block slides up and down, and then the cart is braked or is normally pushed to move back and forth.

Further, a plurality of teeth of a cogwheel have evenly been arranged in the brake disc periphery, the teeth of a cogwheel is followed the direction setting of brake lever, adjacent two form between the teeth of a cogwheel with brake lever tip assorted draw-in groove, the brake lever is in gliding in-process card is gone into from top to bottom to the slider the draw-in groove or deviate from the draw-in groove.

Furthermore, the supporting rod is provided with a limiting mechanism which can pull up the sliding block to prevent the brake rod from clamping the brake disc in the moving process of the cart.

Further, the limiting mechanism comprises a circular ring and a spring; the circular ring is fixedly sleeved on the supporting rod and corresponds to the upper part of the sliding block; the upper end of the spring is fixedly connected with the circular ring, and the lower end of the spring is fixedly connected with the sliding block and pulls up the sliding block.

Furthermore, a pedal which is stepped downwards or lifted upwards through a foot part to drive the sliding block to slide up and down is arranged on one side of the sliding block.

The invention has the beneficial effects that: the brake mechanism can realize the braking or the brake release of the cart only by stepping down or lifting up the pedal by feet, and is convenient and quick.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

As shown in fig. 1, a brake mechanism of a cart includes a support rod 1, a rotation shaft 2, and a roller 3. The upper end of the supporting rod 1 is fixedly connected with the corresponding position of the cart, and the lower end of the supporting rod is fixed with a base 4. The rotating shaft 2 can rotatably penetrate through the base 4, and the rollers 3 are respectively fixed at two ends of the rotating shaft 2. The support rod 1 is sleeved with a sliding block 5 capable of sliding up and down, and two ends of the sliding block 5 are respectively fixed with a brake rod 6 which slides down and then clamps the roller 3 to prevent the roller 3 from rolling to brake the cart.

And a brake disc 7 is fixed on one side of the roller 3 close to the rotating shaft 2. The brake rod 6 is horizontally arranged, the end part of the brake rod corresponds to the brake disc 7 up and down, the brake disc 7 is clamped or the brake disc 7 is loosened in the process that the slide block 5 slides up and down, and then the cart is braked or is normally pushed to move back and forth. As shown in fig. 2, a plurality of gear teeth 8 are uniformly arranged on the periphery of the brake disc 7, the gear teeth 8 are arranged along the direction of the brake rod 6, two adjacent gear teeth 8 form a clamping groove 9 matched with the end of the brake rod 6, and the brake rod 6 is clamped into the clamping groove 9 or separated from the clamping groove 9 in the process of up-and-down sliding of the sliding block 5. As shown in fig. 3, a pedal 12 is disposed on one side of the sliding block 5 and used for driving the sliding block 5 to slide up and down by stepping down or lifting up with a foot.

And the supporting rod 1 is provided with a limiting mechanism which pulls up the sliding block 5 to prevent the brake rod 6 from clamping the brake disc 7 in the moving process of the cart. The limiting mechanism comprises a circular ring 10 and a spring 11. The circular ring 10 is fixedly sleeved on the support rod 1 and corresponds to the upper part of the sliding block 5. The upper end of the spring 11 is fixedly connected with the circular ring 10, and the lower end of the spring is fixedly connected with the sliding block 5 and pulls up the sliding block 5.

When the cart needs to be moved, the sliding block 5 is limited on the supporting rod 1 and above the corresponding brake disc 7 under the action of the spring 11, namely the roller 2 can freely roll without being braked. When the cart is transferred to the destination, the cart needs to be braked: the pedal 12 is stepped by a foot to drive the slide block 5 to slide downwards, the slide block 5 slides downwards and drives the brake rod 6 to synchronously move downwards, and after the brake rod 6 moves downwards for a certain distance, two ends of the brake rod are respectively clamped into the clamping grooves 9 on the brake disc 7 of the roller 2, so that the roller 2 is limited from rolling to brake the cart. When the cart needs to be transferred again, the pedal 12 is lifted upwards through the foot, the pedal 12 drives the brake rod 6 to move upwards and disengage from the clamping groove 9, so that the roller 2 can normally roll, and the cart is braked.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
