Description

Technical Field

[0001] The utility model relates to the technical field of barrier-free ramps, in particular to a novel barrier-free ramp. Background Art

[0002] As an important part of modern urban infrastructure, barrier-free ramps are designed to provide convenience for people with limited mobility (such as disabled people using wheelchairs, the elderly, etc.), allowing them to enter and exit buildings more freely and cross the ground at different heights. As society's demand for barrier-free environments increases, the design and function of barrier-free ramps are also constantly improving and perfecting.

[0003] However, the existing barrier-free ramps still have some shortcomings in actual use:

[0004] Poor mobility: Traditional barrier-free ramps are usually designed as fixed structures and lack mobility. This limits the scope of use of the ramps, and when the ramps need to be frequently moved (such as temporary events, transfers between different floors, etc.), users have to rely on other auxiliary tools or manual handling, which increases the complexity and inconvenience of use.

[0005] Insufficient stability: Some movable barrier-free ramps ignore stability in their design. Especially when the ramps are in use, due to the lack of effective fixing and anti-slip measures, they are prone to sliding or tilting, posing a safety hazard to users.

[0006] Difficulty in maintenance and replacement: Some components of barrier-free ramps (such as anti-slip surfaces) are prone to wear or damage after long-term use, but due to design limitations, these components are often difficult to disassemble and replace, increasing the difficulty and cost of maintenance. Utility Model Content

[0007] 1. Technical issues to be resolved

[0008] In view of the deficiencies in the prior art, the utility model provides a novel barrier-free ramp to solve the above problems.

[0009] (II) Technical solution

[0010] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a new barrier-free ramp, comprising a ramp body, a vertical surface on the back of the ramp body being provided with an up-and-down sliding mounting groove, a U-shaped clamping plate being installed inside the up-and-down sliding mounting groove, rollers being installed on the outer sides of the left and right bent ends of the U-shaped clamping plate, a vertical mounting groove recessed toward the inside of the ramp body being provided at the center of the groove surface on the back side of the up-and-down sliding mounting groove, a lifting drive mechanism being provided inside the vertical mounting groove for driving the U-shaped clamping plate to slide up and down inside the up-and-down sliding mounting groove, a slope surface mounting groove being provided at the slope surface position of the ramp body, and an anti-slip slope surface being installed inside the slope surface mounting groove.

[0011] As a preferred technical solution of the utility model, the lifting drive mechanism specifically includes the following structure:

[0012] A reduction motor installed at the top of the vertical installation slot;

[0013] A driving screw connected to the output end of the reduction motor;

[0014] A screw rod sleeve is threadedly sleeved on the driving screw rod, and the outer tube wall of the screw rod sleeve is connected to the center of the inner side surface of the U-shaped clamping plate.

[0015] As a preferred technical solution of the utility model, guide grooves are provided on both sides of the back groove surface of the up and down sliding installation groove, and guide components cooperating with the U-shaped clamping plate to slide up and down are installed inside the guide grooves on both sides.

[0016] As a preferred technical solution of the utility model, the guide assembly specifically includes the following structure:

[0017] A guide post installed inside the guide groove;

[0018] A guide sleeve is slidably sleeved on the guide column, and the outer tube wall of the guide sleeve is in contact with the inner side surface of one end on the same side of the U-shaped clamping plate.

[0019] As a preferred technical solution of the utility model, the top surface of the anti-skid slope is evenly provided with a plurality of transversely distributed anti-skid convex strips.

[0020] As a preferred technical solution of the utility model, the anti-slip slope is specifically designed to be separated from the ramp body, and the anti-slip slope is specifically snap-connected to the inside of the slope mounting groove.

[0021] As a preferred technical solution of the utility model, a plurality of anti-slip convex strips are evenly arranged on the bottom surface of the ramp body.

[0022] Compared with the prior art, the utility model provides a new barrier-free ramp with the following beneficial effects:

[0023] Flexible transfer and positioning mode conversion: The new barrier-free ramp is designed with a lifting drive mechanism, which allows the ramp to be flexibly converted between transfer and positioning modes. In transfer mode, the rollers on the U-shaped clamping plate contact the ground, making it easier to move and carry the ramp. In positioning mode, the rollers are off the ground, and the ramp body is in close contact with the ground through the anti-slip bumps on the bottom, providing stable support to ensure the safety and stability of users when going up and down the slope.

[0024] Improved mobility: The roller design allows the ramp to be easily moved when not in use. The operator only needs to lift the center of the front end of the ramp to drag the entire barrier-free ramp for transfer. This design greatly improves the mobility of the ramp, making it easier to transfer between different locations.

[0025] Enhanced stability: In positioning mode, the anti-skid bumps on the bottom of the ramp body contact the ground, providing sufficient friction to prevent the ramp from sliding during use. At the same time, the design of the guide component ensures the stability and guidance of the U-shaped card plate when sliding up and down, further enhancing the overall stability of the ramp.

[0026] Anti-slip slope that is easy to disassemble and replace: The anti-slip slope is designed to be separated from the ramp body and is specifically snapped into the inside of the slope installation groove for easy disassembly and replacement. This design is not only easy to maintain and clean, but also allows the anti-slip slope of different materials or designs to be replaced as needed to adapt to different usage environments and needs.

[0027] This new barrier-free ramp achieves flexible conversion between transfer and positioning modes through innovative design and structure, which not only ensures mobility but also enhances overall stability. This design not only improves the practicality and convenience of the ramp, but also provides users with a safer and more comfortable experience. Through the synergy of key components such as the lifting drive mechanism, guide components and anti-slip slope, the ramp can adapt to a variety of usage scenarios and meet the needs of different users.

[0044] See also Figure 1-8 , a new type of barrier-free ramp:

[0045] Design of ramp body 1:

[0046] The ramp body 1 is a structure with a certain slope, which is used to facilitate wheelchairs or pedestrians to go up and down. The vertical surface of the back is provided with an up and down sliding installation slot 2 for installing and fixing a U-shaped card plate 3.

[0047] Installation of the up and down sliding mounting slot 2 and the U-shaped mounting plate 3:

[0048] The up-and-down sliding mounting slot 2 is a vertical slot, and a U-shaped clamping plate 3 is installed inside. Rollers 4 are installed on the outer sides of the left and right bent ends of the U-shaped clamping plate 3. The rollers 4 on both sides are designed to ensure the movable performance of the entire barrier-free ramp when not in use. At the same time, after the U-shaped clamping plate 3 slides upward in the up-and-down sliding mounting slot 2, the rollers 4 on both sides are separated from the ground, and the entire barrier-free ramp can be used.

[0049] Design of lifting drive mechanism 5:

[0050] The lifting drive mechanism 5 is installed in the vertical installation groove 11 at the center of the back side groove surface of the up-and-down sliding installation groove 2. It includes a reduction motor 51 installed at the top of the vertical installation groove 11, and the output end of the reduction motor 51 is connected to the driving screw 52. The driving screw 52 is threadedly sleeved with a screw sleeve 53, and the outer tube wall of the screw sleeve 53 is connected to the center of the inner side surface of the U-shaped clamping plate 3. Driven by the reduction motor 51, the driving screw 52 rotates, so that the screw sleeve 53 can drive the U-shaped clamping plate 3 to slide up and down in the up-and-down sliding installation groove 2, thereby realizing the operation of driving the rollers 4 on both sides to support on the ground or off the ground.

[0051] Design of guide assembly 6:

[0052] Both sides of the back side groove surface of the up-and-down sliding mounting slot 2 are provided with guide grooves 12, and a guide assembly 6 is installed inside the guide groove 12. The guide assembly 6 includes a guide column 61 installed inside the guide groove 12 and a guide sleeve 62 slidably sleeved on the guide column 61. The outer tube wall of the guide sleeve 62 is in contact with the inner side surface of one end on the same side of the U-shaped clamping plate 3, ensuring the stability and guidance of the U-shaped clamping plate 3 when sliding up and down.

[0053] Design of anti-slip slope 8:

[0054] The ramp body 1 is provided with a ramp surface mounting groove 7 at the slope surface position, and an anti-skid ramp surface 8 is installed inside the ramp surface mounting groove 7. The top surface of the anti-skid ramp surface 8 is evenly provided with a plurality of transversely distributed anti-skid convex strips 81 to increase the friction of the slope surface and prevent the user from slipping when going up and down the slope. The anti-skid ramp surface 8 is designed as a separate part from the ramp body 1, and is specifically snapped into the inside of the ramp surface mounting groove 7, which is convenient for disassembly and replacement.

[0055] Design of the bottom surface of the ramp body 1:

[0056] A plurality of anti-skid convex strips 81 are evenly arranged on the bottom surface of the ramp body 1 to increase the friction between the ramp and the ground and prevent the ramp from sliding during use.

[0057] How it works

[0058] The ramp body 1 is placed at a position where it is needed, ensuring that the anti-skid convex strips 81 on its bottom surface are in contact with the ground to provide sufficient friction.

[0059] The operator starts the reduction motor 51 in the lifting drive mechanism 5 .

[0060] The reduction motor 51 drives the screw rod 52 to rotate.

[0061] The screw sleeve 53 on the driving screw 52 rotates accordingly and moves up and down along the screw.

[0062] The screw sleeve 53 drives the U-shaped clamping plate 3 to slide upward in the up-and-down sliding installation slot 2 .

[0063] As the U-shaped clamping plate 3 rises, the rollers 4 on both sides gradually leave the ground.

[0064] When the U-shaped clamping plate 3 is completely raised, the roller 4 is completely off the ground.

[0065] When the ramp needs to be retracted, the operator starts the reduction motor 51 again, but this time in reverse rotation.

[0066] The screw rod 52 is driven to rotate in the opposite direction, and the screw rod sleeve 53 drives the U-shaped clamping plate 3 to slide downward in the up-and-down sliding installation slot 2 .

[0067] The U-shaped clamping plate 3 descends, and the rollers 4 on both sides gradually touch the ground.

[0068] When the U-shaped clamping plate 3 is completely lowered, the roller 4 is completely in contact with the ground.

[0069] The ramp body 1 can be easily moved by the rollers 4 on both sides, and the operator can lift the center of the front end of the ramp body 1 with his hands to drag the entire barrier-free ramp for transfer.
