There are side blocks between two adjacent columns. Casters are provided at the bottom of the columns. There are guide holes on the bottom plate. There are guide posts slidingly connected in the guide holes. , the top of the guide column is provided with a suspension plate, and the bottom is provided with a first brake block. The guide column is covered with a compression spring with one end against the suspension plate and the other end against the bottom plate. The column is provided with a limiting suspension plate. The first limiting piece of movement.

The utility model is further configured as follows: the bottom plate is provided with a rope hole, the bottom of the bottom plate is provided with a bracket, a swing arm is rotatably connected to the bracket, the swing arm has a long section arm and a short section arm, and the short section arm is provided with a For the following second brake block, a rope with one end connected to the suspension plate and the other end connected to the long arm is inserted into the rope hole.

The utility model is further configured such that a second limiting member provided on the bracket is provided below the long section arm.

The utility model is further configured such that: the guide hole is embedded with a bushing that is sleeved on the guide column, and the bushing is slidably connected to the guide column.

The utility model is further configured such that the caster is a universal caster.

To sum up, the present utility model has the following beneficial effects: the self-adjusting floating trolley involved in the present utility model can maintain the braking state in both overloaded and unloaded states, thus avoiding the need for unloaded carts. The position movement occurs, and the safety hazard caused by overloading of the cart is also prevented. It is safe and reliable to use, has complete overall functions and is highly practical.

Detailed ways

In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the preferred embodiments of the present utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only to further illustrate the features and advantages of the present utility model. , rather than limiting the patent requirements of this utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

The utility model will be further described below in conjunction with the accompanying drawings and preferred embodiments.

Example 1

Referring to Figures 1 and 2, a self-adjusting floating trolley of appropriate weight involved in this embodiment includes four uprights 1 distributed in a two-by-two rectangular array. The center of the uprights 1 is provided near the bottom and connected to all The upright column 1 realizes a fixedly connected base plate 2. There are side blocks 3 between two adjacent upright columns 1. The bottom of the upright column 1 is provided with casters 4. The casters 4 are universal casters. The base plate 2 is provided with guide holes. 5. A guide post 6 is slidably connected in the guide hole 5. The top of the guide post 6 is provided with a suspension plate 7 and the bottom is provided with a first brake block 8. The guide post 6 has one end against the suspension plate and the other end against the suspension plate. The compression spring 9 holds the bottom plate, and the column 1 is provided with a first limiting member 10 to limit the upward movement of the suspension plate.

Further, the bottom plate 2 is provided with a rope hole 11, and a bracket 12 is provided at the bottom of the bottom plate 2. A swing arm 13 is rotatably connected to the bracket 12, and the swing arm 13 has a long arm 131 and a short arm 132. The segment arm 132 is provided with a following second braking block 14, and a rope 15 with one end connected to the suspension plate and the other end connected to the long segment arm is inserted into the rope hole 11.

In this embodiment, when the cart is in an unloaded state, the compression spring 9 opens and lifts the suspension plate 7. The edge of the suspension plate 7 abuts the first limiter 10 and tightens the rope 15. The arm 13 is driven, and the second brake block 14 is pressed against the ground to brake the cart.

When the cart is in an overloaded state, the compression spring 9 contracts, the suspension plate 7 moves downward, and the rope 15 no longer tightens the long arm 131, causing the swing arm 13 to swing down toward the long arm 131 end, and the short arm 132 carries the second brake The block 14 swings up; at the same time, the suspension plate 7 moves downward with the guide column 6 until the first brake block 8 is pressed against the ground to realize braking of the cart.

Example 2

Referring to Figures 1 and 2, the present embodiment relates to a self-adjusting floating cart with appropriate weight, which is further configured on the basis of Embodiment 1. There is a device below the long arm 131. The second limiting member 16 is on the bracket 12 .

In this embodiment, the addition of the second limiting member 16 prevents the long arm 131 from drooping and contacting the ground when the rope 15 is not tightened on the long arm 131, thereby playing a limiting role.

Example 3

Referring to Figures 1 and 2, this embodiment relates to a self-adjusting floating trolley with appropriate weight, which is further configured on the basis of Embodiments 1 and 2 such that the guide hole 5 is embedded with a sleeve. A bushing (not shown in the figure) on the guide column 6 is slidably connected to the guide column.

In this embodiment, the addition of the bushing plays a guiding role when the guide post 6 slides up and down relative to the guide hole 5 .

The utility model relates to a self-adjusting floating trolley of appropriate weight. The trolley can maintain the braking state in both overload and no-load conditions, thereby avoiding positional movement of the trolley when no-load, and also preventing the trolley from being damaged due to overload. There are potential safety hazards, it is safe and reliable to use, the overall function is complete, and it is highly practical.
