Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a wheelbarrow. Background Art

[0002] The wheelbarrow uses the principle of leverage to bring the resistance point of the load close to the fulcrum to make its operation more efficient and also share the load between the wheelbarrow and the operator. Because the wheelbarrow makes it easy to move heavy or large loads, it is indispensable in construction sites, farmlands, and gardens. Especially at construction sites, wheelbarrows are often used for the quick transportation of construction materials such as sand, cement, bricks and stones.

[0003] However, in the prior art, when a wheelbarrow is dumping materials, the collision of the wheelbarrow bucket with the ground may cause damage to the wheelbarrow bucket or other parts, such as deformation of the wheelbarrow bucket, breakage of the bracket, etc., thereby affecting the service life and function of the wheelbarrow. The collision may also cause sudden material flow or unstable dumping process, increasing the risk of injury to the operator and surrounding personnel, posing a safety hazard. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problems in the prior art that when a wheelbarrow is dumping materials, the collision of the wheelbarrow bucket with the ground may cause damage to the wheelbarrow bucket or other parts, such as deformation of the wheelbarrow bucket, breakage of the bracket, etc., thereby affecting the service life and function of the wheelbarrow, and the collision may cause sudden material flow or unstable dumping process, increasing the risk of injury to the operator and surrounding personnel, and posing a safety hazard, and a wheelbarrow is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a wheelbarrow, including a frame body, a side surface of the frame body is rotatably connected to a bucket body, one side surface of the bucket body is fixedly connected to two buffer assemblies, the buffer assembly includes a damper, one end of the damper is fixedly connected to a mounting plate, one side surface of the mounting plate is fixedly connected to a first spring, one end of the first spring is fixedly connected to the outer surface of the bucket body, and the upper surface of the frame body is fixedly connected to a connecting rod.

[0006] Furthermore, a wear-resistant pad is fixedly connected to one side surface of the two mounting plates, and the two wear-resistant pads are arranged in a mirror image.

[0007] Furthermore, the outer surface of the truck body and the outer surface of the frame body are fixedly connected by two connection components, and the connection components include a mounting tube, and a fixing rod is embedded in the inner wall surface of the mounting tube.

[0008] Furthermore, one end of the fixing rod is fixedly connected to a support block, one side surface of the support block is fixedly connected to a bidirectional bearing, the outer surface of the fixing rod near one end is sleeved with a connecting pipe, and the outer surface of the connecting pipe is fixedly connected to the outer surface of the truck body.

[0009] Furthermore, a second spring is fixedly connected to one side surface of the bidirectional bearing, one end of the second spring is fixedly connected to one side surface of a mounting tube, and an outer surface of the mounting tube is fixedly connected to an outer surface of the frame body.

[0010] Furthermore, a clamping block is fixedly connected to the outer surface of the fixing rod, and the clamping block is embedded in the inner wall surface of the mounting tube.

[0011] Furthermore, a buffer pad is fixedly connected to the upper surface of the connecting rod, and the upper surface of the buffer pad is in contact with the bottom surface of the truck bucket body.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, when it is necessary to dump the truck body, the handle position of the frame body is lifted upward to rotate the truck body and make it close to the ground. When the two mounting plates are in contact with the ground, the two dampers and the two first springs are squeezed. The compression stroke of the two dampers and the two first springs absorbs kinetic energy and provides buffering to avoid damage to the truck body due to collision with the ground, thereby ensuring the service life and function of the components, preventing sudden material flow or unstable dumping process caused by collision, reducing the risk of injury to the operator and surrounding personnel, and improving safety during use.

[0014] 2. In the utility model, the wear-resistant pad prevents the mounting plate from rubbing against the ground, thereby ensuring the service life of the mounting plate. The support block is pulled, and the two-way bearing pulls the second spring to disengage the two clamping blocks from the mounting tube. Then the two fixing rods are rotated, and the two clamping blocks are misaligned with the grooves inside the mounting tube through the two-way bearing. One end of the two fixing rods is disengaged from the connecting tube, so that one end of the bucket body is disengaged from the frame body. The bucket body can be rotated smoothly, avoiding relative rotation between the bucket body and the frame body during use, thereby improving the use experience. When the bucket body is in use, the buffer pad avoids friction with the connecting rod, thereby ensuring the service life of components. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In this embodiment, when it is necessary to dump the truck body 2, the handle position of the frame body 1 is lifted upward to rotate the truck body 2 and make it close to the ground. When the two mounting plates 402 are in contact with the ground, the two dampers 401 and the two first springs 403 are squeezed. The compression stroke of the two dampers 401 and the two first springs 403 absorbs kinetic energy and provides buffering to prevent the truck body 2 from colliding with the ground and causing damage to the truck body 2, thereby ensuring the service life and function of the components, preventing the sudden flow of materials or unstable dumping process caused by the collision, reducing the risk of injury to the operator and surrounding personnel, and improving safety during use.
