Technical Field

[0001] This utility model relates to the technical field of transportation equipment, and in particular to a handcart. Background Technology

[0002] As a simple and practical means of transportation, handcarts are widely used in various scenarios for transporting goods. For example, in laboratories, handcarts are used to transport experimental tools and chemical reagents.

[0003] Traditional handcarts typically consist of a body with wheels mounted on the bottom, and a flatbed or basket fixed to the body for carrying goods. To transport goods, the goods are placed in the flatbed or basket, and the cart is pushed to move it.

[0004] The handcarts mentioned above can effectively transfer goods on flat ground, but in actual transportation, they often need to face uphill and downhill sections. When the handcart is going uphill or downhill, the flatbed or storage basket will tilt, causing the goods to tilt or even tip over, which poses certain safety hazards when transporting fragile goods or hazardous chemicals. Utility Model Content

[0005] This utility model provides a handcart to solve the safety hazards of handcarts transporting fragile goods or hazardous chemicals up and down slopes in the prior art. It can effectively avoid the problem of goods tilting or tipping over when going up and down slopes, and reduce safety hazards.

[0006] This utility model provides a handcart, including: a cart body, a basket, and a lifting component;

[0007] The vehicle body is connected to a suspension beam;

[0008] The suspended basket is connected to the lifting beam via the lifting component, and the suspended basket is suspended below the lifting beam under the action of gravity;

[0009] The lifting component can swing relative to the lifting beam in the direction of movement of the vehicle body, so that the posture of the basket can remain stable under the action of gravity.

[0010] According to the present invention, a handcart also includes a positioning structure for limiting the relative movement of the basket and the cart body.

[0011] According to the present invention, a handcart is provided, the cart body including a frame, wheels and handles;

[0012] A braking device is provided at the wheel, and a brake handle is provided at the handrail. The brake handle is connected to the braking device.

[0013] According to the present invention, a handcart is provided in which the brake handle is elastically reset connected to the handrail; when the brake handle moves close to the handrail, the brake device is controlled to be in the released state; when the brake handle moves away from the handrail and resets, the brake device is controlled to be in the braking state.

[0014] According to the present invention, a handcart is provided, wherein the lifting component includes at least two sets of lifting units; the two sets of lifting units are used to connect the lifting beam and the end of the basket perpendicular to the direction of movement of the vehicle body, respectively; each set of lifting units is used to connect the two sides of the lifting beam along the direction of movement of the vehicle body, respectively.

[0015] According to the present invention, a handcart is provided, wherein the hoisting unit includes a hoisting rod, one end of which is rotatably connected to the hoisting beam via a rotating component, and the other end is fixedly connected to the hoisting basket.

[0016] According to the present invention, a handcart is provided, wherein the rotating component includes a collar, the collar being rotatably sleeved on the lifting beam; the lifting rod is fixedly connected to the collar.

[0017] According to the present invention, a handcart is provided, the positioning structure comprising:

[0018] A positioning hole is provided on the collar;

[0019] A positioning element, adapted to pass through the positioning hole and engage with the lifting beam to limit the relative rotation of the collar and the lifting beam.

[0022] The handcart provided by this utility model allows goods to be placed in a hanging basket and transported by pushing the cart. When going up or down slopes, the cart will tilt relative to the horizontal plane. However, since the hanging basket is suspended below the lifting beam and the lifting components can swing relative to the lifting beam in the direction of the cart's movement, when the cart tilts, the hanging basket will cause the lifting components to swing under the action of gravity, thereby adjusting its posture to always remain horizontal. This effectively avoids the problem of goods tilting or tipping over when going up or down slopes and reduces safety hazards. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] To facilitate understanding of the handcart provided by this utility model, its application background will be introduced first. The handcart is a commonly used transportation tool that can be used for cargo transportation in various scenarios.

[0032] Traditional handcarts typically consist of a cart body with wheels mounted on the bottom, and a flatbed or basket fixed to the body. To transport goods, the goods are placed in the flatbed or basket, and the cart is pushed to move the goods.

[0033] However, when the aforementioned handcarts go up or down slopes, the flatbed or baskets will tilt, causing the goods to tilt or even tip over, posing a certain safety hazard when transporting fragile goods or hazardous chemicals.

[0034] To address the aforementioned problems, this utility model provides a handcart that can effectively prevent goods from tilting or tipping over when going up or down slopes, thus reducing safety hazards.

[0035] The following is combined with Figures 1-4 This utility model describes a handcart.

[0036] Reference Figure 1 and Figure 2 A handcart includes a cart body 10, a basket 11, and a lifting component 12; wherein, a lifting beam 13 is connected to the cart body 10; the basket 11 is connected to the lifting beam 13 through the lifting component 12, and the basket 11 is suspended below the lifting beam 13 under the action of gravity; the lifting component 12 can swing relative to the lifting beam 13 in the direction of movement of the cart body 10, so that the posture of the basket 11 can remain stable under the action of gravity.

[0037] In practical applications, goods are placed in the basket 11 and the vehicle body 10 is moved to transport them. When going up or down slopes, the vehicle body 10 will tilt relative to the horizontal plane. However, since the basket 11 is suspended below the lifting beam 13 and the lifting component 12 can swing relative to the lifting beam 13 in the direction of movement of the vehicle body 10, when the vehicle body 10 tilts, the basket 11 will drive the lifting component 12 to swing under the action of gravity, thereby adjusting its own posture to always be horizontal. This effectively avoids the problem of goods tilting or tipping over when going up or down slopes and reduces safety hazards.

[0038] To ensure the stability of the suspended platform 11, in one embodiment of this utility model, the lifting beam 13 is configured as a crossbeam, with its two ends fixedly connected to the opposite sides of the vehicle body 10, and the axis of the lifting beam 13 is perpendicular to the direction of movement of the vehicle body 10. The lifting component 12 includes multiple lifting units 120, one end of which is connected to the lifting beam 13, and the other end is connected to the suspended platform 11.

[0039] Specifically, the hoisting unit 120 is provided in at least two sets. The two sets of hoisting units 120 are used to connect the lifting beam 13 and the ends of the basket 11 perpendicular to the direction of movement of the vehicle body 10, respectively, to ensure the stability of both ends of the basket 11. Each set of hoisting units 120 is used to connect both sides of the lifting beam 13 along the direction of movement of the vehicle body 10, to ensure the stability of both sides of the basket 11. By using multiple sets of hoisting units 120, the center of gravity of the basket 11 can be located at its own geometric center, thereby achieving stable suspension of the basket 11 below the lifting beam 13.

[0040] It is understandable that different shapes of the suspended platform 11 will result in different numbers and connection positions of the hoisting units 120. For example, when the suspended platform 11 is a rectangular frame structure, two sets of hoisting units 120 can be arranged. The two sets of hoisting units 120 are used to connect the two ends of the suspended platform 11 in the length direction. Each set of hoisting units 120 has two members, and the two hoisting units 120 are used to connect the two sides of the suspended platform 11 in the width direction. In this way, four hoisting units 120 are connected to the four corners of the suspended platform 11 to ensure the stable suspension of the suspended platform 11.

[0041] Understandably, the lifting unit 120 can use flexible lifting ropes. In this case, when the vehicle body 10 tilts relative to the horizontal plane, the basket 11, under the influence of gravity, will cause the flexible lifting ropes to swing and adjust its own posture. Alternatively, the lifting unit 120 can use a rigid boom, with one end rotatably connected to the lifting beam 13 and the other end fixedly connected to the basket 11. In this case, when the vehicle body 10 tilts relative to the horizontal plane, the basket 11, under the influence of gravity, will cause the rigid boom to rotate around the lifting beam 13, thereby adjusting its own posture.

[0042] However, although the flexible suspension ropes allow the basket 11 to adjust its posture under the influence of gravity, the ropes have degrees of freedom in all directions, making it difficult to control the swing direction of the basket 11 during the movement of the vehicle body 10, posing a risk of collision with the vehicle body 10. Therefore, in this embodiment, the hoisting unit 120 uses a rigid lifting rod.

[0043] The rigid boom restricts the swing of the basket 11 in other directions, allowing the basket 11 to swing only in the direction of movement of the vehicle body 10. This achieves effective control over the swing direction of the basket 11, effectively avoiding the risk of collision between the basket 11 and the vehicle body 10 while adjusting the posture of the basket 11, thus improving the stability of the handcart in transporting goods.

[0044] In one embodiment of this utility model, the suspended basket 11 has a rectangular frame structure; there are two sets of suspension rods, each set having two rods. The two sets of suspension rods are respectively arranged at both ends of the suspended basket 11 along the axial direction of the suspension beam 13. One end of the two rods in each set is fixedly connected to the side of the suspended basket 11 along the direction of movement of the vehicle body 10, and the other end converges on the suspension beam 13 and is rotatably connected to the suspension beam 13 through a rotating component.

[0045] In one embodiment of this utility model, referring to Figure 3 and Figure 4 The rotating component includes a collar 20, which is rotatably sleeved on the lifting beam 13. The end of the lifting rod is fixedly connected to the collar 20, thus realizing the rotatable connection between the lifting rod and the lifting beam 13.

[0046] To improve stability, a rotating groove 130 is provided on the lifting beam 13 at the position corresponding to the collar 20. The collar 20 is rotatably embedded in the rotating groove 130. The rotating groove 130 can restrict the position of the collar 20, prevent the collar 20 from moving along the axial direction of the lifting beam 13, and improve the stability of the suspended basket 11.

[0047] Understandably, depending on actual needs, lubricating oil can be added or ball bearings can be installed between the collar 20 and the lifting beam 13 to improve the smoothness of the collar 20's rotation.

[0048] Of course, the rotational connection between the boom and the beam 13 includes, but is not limited to, the rotational connection methods listed above. Other methods that can achieve the rotational connection between the boom and the beam 13 are also applicable, and the specific method can be selected according to actual needs.

[0049] In one embodiment of this utility model, the handcart further includes a positioning structure for limiting the relative movement of the basket 11 and the vehicle body 10. The positioning structure limits the relative movement of the basket 11 and the vehicle body 10, thereby preventing the basket 11 from swaying when the handcart transports goods on a flat road.

[0050] In some alternative embodiments, the positioning structure can be disposed between the rotating component and the lifting beam 13, indirectly restricting the relative movement of the suspended platform 11 and the vehicle body 10 by limiting the relative rotation of the rotating component and the lifting beam 13. The positioning structure can also be disposed between the suspended platform 11 and the vehicle body 10, for example, by binding them together with cable ties or connecting them with rings, hooks, etc., thereby directly restricting the relative movement of the suspended platform 11 and the vehicle body 10. The above two forms of positioning structure can be selected according to actual needs.

[0051] In one embodiment of the present invention, the positioning structure includes a positioning hole 200 and a positioning element 30; wherein, the positioning hole 200 is disposed on the collar 20; the positioning element 30 is adapted to pass through the positioning hole 200 and cooperate with the lifting beam 13 to limit the relative rotation between the collar 20 and the lifting beam 13.

[0052] Specifically, the positioning component 30 can be a positioning bolt, which is threaded to the positioning hole 200 and can abut against the lifting beam 13.

[0053] In practical applications, when the handcart moves on flat ground, tightening the positioning bolts causes the ends of the bolts to pass through the positioning holes 200 and abut against the outer periphery of the lifting beam 13. Under the action of friction and preload, the relative rotation between the collar 20 and the lifting beam 13 is restricted, thus ensuring the stability of the suspended platform 11 when the handcart moves on flat ground. When the handcart moves uphill or downhill, loosening the positioning bolts causes the ends of the bolts to separate from the outer periphery of the lifting beam 13, allowing the collar 20 to return to a state of free rotation, enabling the suspended platform 11 to maintain stability under the influence of gravity.

[0054] To facilitate tightening, a tightening handle can be installed at the end of the positioning bolt away from the lifting beam 13.

[0055] In another embodiment, a fixing hole can be made on the lifting beam 13. When the handcart moves on flat ground, the positioning hole 200 corresponds to the position of the fixing hole. The positioning member 30 is an insert that is suitable for passing through the positioning hole 200 and the fixing hole in sequence, thereby restricting the relative rotation between the collar 20 and the lifting beam 13.

[0056] Of course, the positioning element 30 includes, but is not limited to, the structures or forms listed above, and will not be listed one by one in this embodiment of the utility model.

[0057] In one embodiment of this utility model, the vehicle body 10 includes a frame 100, wheels 101, and a handle 102. The specific structure of the frame 100 can be designed according to actual needs, and no specific limitations are imposed in this embodiment. The two ends of the suspension beam 13 are fixedly connected to the opposite sides of the frame 100. A braking device is provided at the wheel 101, and a brake handle 14 is provided at the handle 102. The brake handle 14 is connected to the braking device. The brake handle 14 can control the braking device to brake, thereby ensuring the safety of the handcart's movement.

[0058] Specifically, the brake handle 14 is elastically reset connected to the handrail 102; when the brake handle 14 moves close to the handrail 102, the brake device is in the released state; when the brake handle 14 moves away from the handrail 102 and resets, the brake device is in the braking state.

[0059] In actual operation, when the staff grips the brake handle 14, the brake device is in the released state, and the handcart can be pushed. When the staff accidentally releases the brake handle 14 due to distraction or other reasons, the brake device is in the braking state to prevent the handcart from rolling away, thereby improving the safety of the handcart moving on the slope.

[0060] It should be noted that the brake handle 14 can refer to the cable brake handle or disc brake system brake handle in the prior art; the brake device can refer to the rim brake, disc brake or drum brake in the prior art. The above-mentioned brake handle 14 and brake device are mature prior art and can be obtained commercially. The present invention does not improve the principle of the brake handle 14 and brake device. Therefore, the specific structure of the brake handle 14 and brake device will not be described in detail.

[0061] In one embodiment of this utility model, the suspended basket 11 can be configured as a closed structure or as a top-open structure, and the specific design can be made according to actual needs.

[0062] In one embodiment of this utility model, the bottom and / or sides of the inner cavity of the basket 11 are provided with cushioning material to reduce the shaking and bumping of goods during transportation.

[0063] Specifically, cushioning materials can include bubble wrap, foam board, pearl cotton, honeycomb cardboard, or air column bags.

[0064] In one embodiment of this utility model, a limiting device can also be set in the basket 11 to limit the goods in the basket 11, thereby reducing the problem of goods sliding and colliding in the basket 11 due to inertia when the handcart is pushed at a non-uniform speed.

[0065] Specifically, the limiting device can be set as a rubber anti-slip mat, which is placed at the bottom of the basket 11. The rubber anti-slip mat can effectively prevent the goods from sliding relative to each other at the bottom of the basket 11, thereby reducing the collision between the goods and the basket 11, and between the goods themselves.

[0066] Specifically, the limiting device can also be set as a perforated shelf. When transporting glassware such as test tubes and beakers, the glassware can be inserted one by one into the holes of the shelf, thereby avoiding the problem of the glassware shaking and bumping into each other due to inertia during transportation.

[0067] Of course, the limit device and the basket 11 can be set to be detachable, so that different models and specifications of limit devices can be disassembled and replaced according to different goods.

[0068] It is understood that, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of the different embodiments or examples.

[0069] The handcart provided by this utility model allows goods to be placed in the basket 11 and transported by pushing the cart body 10. When going up or down slopes, the cart body 10 will tilt relative to the horizontal plane. However, since the basket 11 is suspended below the lifting beam 13 and the lifting component 12 can swing relative to the lifting beam 13 in the direction of movement of the cart body 10, when the cart body 10 tilts, the basket 11 will drive the lifting component 12 to swing under the action of gravity, thereby adjusting its own posture to always be horizontal. This effectively avoids the problem of goods tilting or tipping over when going up or down slopes and reduces safety hazards.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
