DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 3The utility model discloses a barrier-free device for pedestrian passages on urban roads, including a first support plate 9 and a second support plate 10, and also includes: a lower pedal 3 is hingedly connected to the edge of one side of the first support plate 9, and the connection at the edge can prevent the lower pedal 3 from colliding with the first support plate 9 when rotating, so that the lower pedal 3 has a larger rotation angle, and an upper pedal 4 is provided above the second support plate 10 away from the side of the first support plate 9, and the height of the upper pedal 4 is adjusted according to the height of the step, and at least one connecting pedal 5 is provided between the upper pedal 4 and the lower pedal 3; there is a gap between the connecting pedals 5 and they are slidably connected, and there is a gap between the connecting pedal 5 and the lower pedal 3 and the upper pedal 4 and they are slidably connected.

[0025] In this embodiment, the lengths of the lower pedal 3, the upper pedal 4 and the connecting pedal 5 are the same. The connecting pedal 5 and the upper pedal 4 are slid to change the size of the gap between them, thereby changing the overall length of the device to adapt to steps of different lengths. The maximum distance of the gap should not exceed 3 cm to avoid large bumps when the wheelchair passes.

[0026] Combination Figure 2-Figure 4 The lower pedal 3 and the connecting pedal 5 are symmetrically fixed with connecting sliders 15 on both sides near one end of the upper pedal 4, and the upper pedal 4 and the connecting pedal 5 are symmetrically provided with first slide grooves 17 on both sides near one end of the lower pedal 3, and one side of the first slide groove 17 is an open end. The connecting slider 15 slides in the first slide groove 17 through the open end, thereby driving the lower pedal 3 and the connecting pedal 5 to move to change the size of the gap.

[0027] Combination Figure 4 A cylindrical slider 16 is fixedly provided at one end of the connecting slider 15 close to the first slide groove 17. A limiting groove 161 is provided on the outer surface of the cylindrical slider 16. A second slide groove 171 is provided in the first slide groove 17. A retaining ring 172 is provided in the second slide groove 171. The cylindrical slider 16 slides along the second slide groove 171. The retaining ring 172 fits with the limiting groove 161 to prevent the cylindrical slider 16 from lateral displacement, thereby improving the stability of the device.

[0028] In this embodiment, the connecting slider 15 needs to be made of a material with high load-bearing capacity, because the connecting slider 15 needs to bear the load of pedestrians above while sliding, and is a part that is prone to breakage; when using the device, there is a large friction between the connecting slider and the first slide groove 17 to prevent the upper pedal 4 and the connecting pedal 5 from sliding toward the lower pedal.

[0029] Combination Figure 2 , Figure 3 as well as Figure 5In order to adjust the height of the device, at least two groups of telescopic rods 11 are provided between the second support plate 10 and the upper pedal 4. The telescopic rod 11 includes a sleeve 111, a threaded rod 112, a fastening nut 113 and a limiting nut 114. The lower end of the sleeve 111 is rotatably connected to the rotating shaft 8, the rotating shaft 8 is rotatably connected to the second support plate 10, and the upper end of the threaded rod 112 is hinged to the upper pedal 4. Since both ends of the telescopic rod 11 can rotate, when the height of the device is adjusted, the telescopic rod 11 will not limit the upper pedal 4; the lower end of the threaded rod 112 is located in the sleeve 111, the fastening nut 113 is threadedly connected to the threaded rod 112 outside the sleeve 111, and the limiting nut 114 is threadedly connected to the threaded rod 112 inside the sleeve 111; the outer surface of the sleeve 111 is symmetrically provided with openings 115 to facilitate adjustment of the position of the limiting nut 114.

[0030] In this embodiment, the height of the device is changed by extending and retracting the threaded rod 112. When the device is adjusted to a required height, the fastening nut 113 is turned downward until it fits against the upper surface of the sleeve 111, and the limiting nut 114 is turned upward through the opening 115 so that the limiting nut 114 is in close contact with the inner surface of the sleeve 111 to prevent the threaded rod 112 from moving upward, thereby achieving adjustment of the height of the device.

[0031] Combination Figure 2 , Figure 3 In order to prevent the connecting pedal 5 from bending downward, a support 18 is fixedly provided on the lower surface of the connecting pedal 5, and at least two supports 18 are provided. A support frame 12 is provided between the support 18 and the second support plate 10, and one side of the support frame 12 is rotatably connected to the support 18; at least two rows and two columns of limit blocks 13 are equidistantly fixedly provided on the upper surface of the second support plate 10. When the device is lifted from low to high, the support frame 12 rotates around the support 18 in the direction close to the first support plate 9 and is lifted upward with the device. When the required height is reached, the other side of the support frame 12 is limited by the nearest row of limit blocks 13, thereby supporting the connecting pedal 5.

[0032] In this embodiment, the support frame 12 is preferably installed on the connecting pedal 5 close to the middle of the device so that both sides of the upper part of the device can be evenly stressed.

[0033] Combination Figure 2 , Figure 3 A connecting rod 14 is provided between the first support plate 9 and the second support plate 10. The connecting rod 14 can be a hollow tube to save manufacturing materials. One end of the connecting rod 14 is fixedly connected to the first support plate 9. A cavity is opened on the side of the second support plate 10. The connecting rod 14 fits in the cavity and can slide along the cavity.

[0034] In this embodiment, when the device is elongated or shortened, the second support plate 10 can slide along the connecting rod 14 to approach or move away from the first support plate 9, so that the first support plate 9 and the second support plate 10 remain in the same horizontal plane when the device is laid, without the need for additional flipping actions, thereby improving the convenience of laying the device; at the same time, the connecting rod 14 also plays a lateral limiting role on the second support plate 10 and the first support plate 9, thereby avoiding misalignment of the device after laying and improving the stability of the device.

[0035] Combination Figure 1 , Figure 6 A storage cavity 6 is provided on the upper surface of the second support plate 10, and the storage cavity 6 is used to store the telescopic rod 11 in the retracted state. Both sides of the storage cavity 6 are provided with movable slide grooves 61. The end of the movable slide groove 61 away from the first support plate 9 is provided with a sinking groove 62. The sinking groove 62 has a semi-arc structure, and the arc radius is the same as the rotating shaft 8. The sinking groove 62 limits the rotating shaft 8, which can prevent the telescopic rod 11 from sliding when bearing weight.

[0036] In this embodiment, when passing normally, the telescopic rod 11 can be lowered to the lowest position, and then the telescopic rod 11 is lifted out of the sinking groove 62 and slides along the moving slide groove 61 toward the first support plate 9. At this time, the lower pedal 3, the upper pedal 4, and the connecting pedal 5 are gradually reduced in inclination until they are horizontal under the drive of the telescopic rod 11, which is convenient for pedestrians to pass normally.

[0037] Combination Figure 1-Figure 3 In order to prevent dirt or objects from falling into the gap of the device during use, a rubber strip 7 is provided in the gap, one side of the rubber strip 7 is fixedly connected to the lower pedal 3 or the connecting pedal 5, and the other side of the rubber strip 7 is fixedly connected to the upper pedal 4 or the connecting pedal 5, and the length of the rubber strip 7 is the same as that of the connecting pedal 5.

[0038] In this embodiment, the rubber strip 7 can be fixed by screws, or by opening grooves on the sides of the lower pedal 3, the upper pedal 4 and the connecting pedal 5, and pressing the rubber strip 7 into the grooves to achieve a fixing effect. The rubber strip 7 can be deformed when the device is stretched or contracted, and will not hinder the movement of the device.

[0039] The working principle and use process of the utility model are as follows: when in use, at the step where the barrier-free device is required, first adjust the telescopic rod 11 to the required height according to the height of the single step, and at the same time lift the upper pedal 4, and fix the height of the telescopic rod 11 by tightening the nut 113 and the limit nut 114; then stretch the lower pedal 3 and the connecting pedal 5 according to the length of the single step, and adjust the position of the support frame 12 at the same time. At this time, the first support plate 9 moves together with the lower pedal 3 and remains stable under the action of the connecting rod 14. When the required length is reached, the support frame 12 contacts with the limit block 13 and is limited by the limit block 13. Then, the corresponding device is laid according to the number of steps. The adjacent lower pedals 3 and upper pedals 4 are connected by connecting plates 19, and rubber strips 7 are fixedly installed in the gaps between the lower pedal 3, the upper pedal 4 and the connecting pedal 5.

[0040] When the device is used for normal people to pass, the telescopic rod 11 can be slid through the movable slide groove 61 and stored in the storage cavity 61, so that the lower pedal 3, the upper pedal 4 and the connecting pedal 5 are gradually reduced in inclination until they are horizontal under the drive of the telescopic rod 11.

[0041] In summary, the barrier-free device for the pedestrian passage on the urban road can change the length of the device to adapt to steps of different spans by providing a slidingly connected lower pedal 3, an upper pedal 4 and a connecting pedal 5, and can adjust the height of the device to adapt to steps of different heights by providing a telescopic rod 11 that can adjust the extension distance, thereby increasing the applicability of the device, allowing wheelchairs to pass smoothly and facilitating use by disabled people; by providing a lower pedal 3, an upper pedal 4 and a connecting pedal 5 that can be connected to each other, a corresponding number of devices can be laid according to the number of steps, thereby improving the convenience of use; by providing a rotatable and retractable telescopic rod 11, the device can be adjusted to a horizontal state to facilitate the normal passage of pedestrians.
