Description

Technical Field

[0001] The utility model relates to a novel speed reduction belt. Background Art

[0002] Speed ​​bumps, also called deceleration ridges, are traffic facilities installed on roads to slow down passing vehicles. They are generally strip-shaped or dot-shaped, made of rubber or metal. They are usually yellow and black to attract visual attention, and slightly bulge the road surface to achieve the purpose of slowing down vehicles. They are generally installed at highway intersections, industrial and mining enterprises, schools, residential entrances and other sections where vehicles need to slow down and sections that are prone to traffic accidents. They are new types of special traffic safety devices used to reduce the speed of motor vehicles and non-motor vehicles.

[0003] For example, a speed bump with automatically adjustable height disclosed in Chinese patent CN202121133961.1 has the following shortcomings in actual use:

[0004] The above patent uses a protruding block to lift the protruding end of the speed bump to change the height of the speed bump. However, the driving mechanism is electrically driven. Due to the environment in which the speed bump is installed, it is not possible to power on each speed bump. If the power is off, the height cannot be adjusted.

[0005] At the same time, the height adjustment of the speed bump is limited. If it is too high, a fault will appear between the fixed base and the speed bump, which will make it inconvenient for cars to pass through. Utility Model Content

[0006] The utility model provides a novel speed reduction belt, which can effectively solve the above problems.

[0007] The utility model is achieved in this way:

[0008] A novel speed bump comprises a bottom shell, and both sides of the opening at the upper end of the bottom shell are hinged with an outward-opening speed bump body;

[0009] Slide seats are slidably arranged on both sides of the bottom of the inner cavity of the bottom shell, and a connecting rod is hinged between the upper end of each slide seat and each speed bump body. A horizontal bidirectional lead screw threadedly connected to the middle part of each slide seat is movably penetrated on both sides of one end of the bottom shell.

[0010] As a further feature, transverse sliding grooves for sliding of each slide seat are provided on both sides of the bottom of the inner cavity of the bottom shell, and the transverse sliding grooves are arranged at both ends of one side of the bottom of the inner cavity of the bottom shell, and the two transverse sliding grooves are connected by a circular hole.

[0011] Furthermore, the bottom of each of the transverse sliding grooves is fitted with the bottom of the inner cavity of the transverse sliding groove, and transverse holes connected to the transverse sliding grooves are opened on both sides of one end of the bottom shell, and the diameter of the transverse hole is larger than the diameter of the transverse bidirectional screw, and one end of the transverse bidirectional screw can be movably penetrated to the inner wall of the bottom shell.

[0012] As a further feature, an upper slot for hinged connection of one end of a connecting rod is provided on the lower ends of the two speed bump bodies away from the sliding seat;

[0013] Under normal conditions, the upper slot and the slide seat are arranged obliquely symmetrically.

[0014] As a further feature, a fixing sleeve is fixedly provided in the middle of the upper end of the bottom of the inner cavity of the bottom shell, and a longitudinal sliding block fixedly connected to the trapezoidal top bar is longitudinally slidably provided inside the fixing sleeve.

[0015] As a further feature, a longitudinal through hole communicating with the interior of the fixing sleeve is provided in the middle of the upper end of the bottom of the inner cavity of the bottom shell, and a longitudinal bolt is threadedly connected to the longitudinal through hole, and the top of the longitudinal bolt abuts against the longitudinal slider and is rotatable.

[0016] As a further feature, the lower ends of the two speed bump bodies on opposite sides are provided with arc surfaces that can abut against the surface of the trapezoidal top strip.

[0017] The beneficial effects of the utility model are:

[0018] (1) The rotation of the horizontal bidirectional screw will cause the slide to move toward each other in the horizontal slide groove. The two slides will push the speed bump body to rotate through the connecting rod, so that the two ends of the speed bump body facing each other are tilted and the height of the speed bump is increased. Since the adjustment end of the horizontal bidirectional screw is located on the outside, the user can adjust the height of the speed bump body in real time. Since the speed bump body is inclined, the height of the speed bump body is effectively reduced, and the fault transition is smoother.

[0019] (2) The longitudinal bolt rotates to push the longitudinal slider upward in the fixing sleeve until the trapezoidal top bar is pressed against the arc surfaces of the two speed bump bodies, thereby achieving a supporting effect and improving the stability of the speed bump body.

[0029] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] Reference Figure 1-5 As shown, a novel speed bump includes a bottom shell 1, and a plurality of bolt holes (such as Figure 2As shown in FIG. 1 , a rotating shaft is rotatably arranged on both sides of the upper end opening of the inner cavity of the bottom shell 1, and the rotating shaft is movable through one side of the speed reduction belt body 2 (as shown in FIG. Figure 1 As shown in the figure, the two speed bump bodies 2 are set to open outwards and a gap is left between the opposite surfaces to facilitate opening and closing. At the same time, the corners of the speed bump bodies 2 are set to arc chamfers to protect tires and pedestrians. The lower ends of the two speed bump bodies 2 on the opposite side are provided with arc surfaces 14, which can abut against the surface of the trapezoidal top bar 13 to support the two speed bump bodies 2, avoid damage to the speed bump body 2 due to excessive force, and avoid downward deformation of the speed bump body 2 due to force, resulting in a reduction in height.

[0031] like Figure 3 , 4 As shown, transverse grooves 9 are provided on both sides of the bottom of the inner cavity of the bottom shell 1, and multiple slide seats 6 slide inside the transverse grooves 9. The inner wall of the transverse grooves 9 and the outer wall of the slide seats 6 are both fitted to reduce the gap to prevent the speed reduction belt body 2 from being moved by force. The transverse grooves 9 are arranged at both ends of one side of the bottom of the inner cavity of the bottom shell 1 (such as Figure 4 As shown), the two transverse slide grooves 9 are connected by a circular hole, and the bottom of each transverse slide groove 9 is fitted with the bottom of the inner cavity of the transverse slide groove 9. The fitting setting can increase the bearing capacity of the speed bump body 2 and will not move downward to reduce the height of the speed bump. Both sides of one end of the bottom shell 1 are provided with transverse holes 7 connected with the transverse slide groove 9, and the diameter of the transverse hole 7 is larger than the diameter of the transverse bidirectional screw 3. It should be noted that the contact position between the transverse bidirectional screw 3 and the bottom shell 1 is set to a smooth surface, so that the transverse bidirectional screw 3 can rotate freely. One end of the transverse bidirectional screw 3 can move through the inner wall of the bottom shell 1. This setting can limit the transverse bidirectional screw 3 (such as Figure 4 As shown), the horizontal bidirectional screw 3 can be rotated according to its own axis.

[0032] An upper groove 10 is provided at the lower end of the two speed reduction belt bodies 2 away from the sliding seat 6. The upper groove 10 is rotatably connected to one end of the connecting rod 11 through a rotating shaft. The end of the connecting rod 11 away from the upper groove 10 is rotatably arranged in the groove at the upper end of the sliding seat 6 through a rotating shaft. The connection method of the rotating shaft is an existing and mature technology and will not be described in detail.

[0033] Under normal circumstances, the upper slot 10 and the slide 6 are arranged obliquely symmetrically. When the two slides 6 move toward each other, the two speed bump bodies 2 can be opened and tilted at one end, thereby increasing the height of the speed bump. A horizontal bidirectional lead screw 3 is movably penetrated through the transverse holes 7 on both sides of one end of the bottom shell 1. The horizontal bidirectional lead screw 3 is threadedly connected to the middle part of the slide 6, thereby driving the two slides 6 to move toward or oppositely.

[0034] A rectangular fixing sleeve 12 is welded to the middle of the upper end of the bottom of the inner cavity of the bottom shell 1, and a longitudinal slider 8 is longitudinally slidably arranged inside the fixing sleeve 12. The upper end of the longitudinal slider 8 is fixedly connected to the lower end of the trapezoidal top bar 13. A longitudinal through hole 5 communicating with the interior of the fixing sleeve 12 is opened in the middle of the upper end of the bottom of the inner cavity of the bottom shell 1. An internal thread is arranged in the longitudinal through hole 5. The internal thread of the longitudinal through hole 5 is connected to the rod thread of the longitudinal bolt 4, and the top of the longitudinal bolt 4 abuts against the longitudinal slider 8 and can rotate.

[0035] It should be noted that a hexagonal groove is formed at one end of the horizontal bidirectional screw 3 located on the outer side of the bottom shell 1 and is recessed in the horizontal through hole 7. The head of the longitudinal bolt 4 is located in the longitudinal through hole 5, thereby avoiding interference of the device during installation or splicing. The longitudinal bolt 4 is preferably a countersunk bolt.

[0036] Among them, all structures of this device constitute a speed bump.

[0037] Principle and process of this utility model:

[0038] Before installing this device on the road,

[0039] When adjusting the height: the user first inserts a tool into the hexagonal groove of the horizontal bidirectional screw 3 and rotates it. The rotation of the horizontal bidirectional screw 3 will cause the slide 6 to move toward each other in the horizontal slide groove 9. The two slides 6 will push the speed belt body 2 to rotate through the rotating shaft and the connecting rod 11. One end of the speed belt body 2 will rotate around the rotating shaft connected to the upper end of the bottom shell 1, so that the two speed belt bodies 2 face each other and increase the height of the speed belt. At the same time, the set arc surface 14 can facilitate the two speed belt bodies 2 to better keep away from each other to avoid interference, and at the same time, it can better fit with the trapezoidal top bar 13 to achieve a supporting effect.

[0040] The transverse bidirectional lead screw 3 is turned over with it, and the height of the two speed reduction belt bodies 2 is reduced.

[0041] After the height is fixed, the user needs to use a tool to rotate the longitudinal bolt 4. When the longitudinal bolt 4 rotates, its rod will rotate toward the fixing sleeve 12 and then push the longitudinal slider 8 to move upward in the fixing sleeve 12 until the trapezoidal top bar 13 is tightly pressed against the arc surfaces 14 of the two speed bump bodies 2, thereby achieving a supporting effect.

[0042] In summary, the device has the advantage that the height of the speed bump can be adjusted during installation and the fault transition is effectively reduced and smoother when the height of the speed bump is increased.

[0043] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
