Description

Technical Field

[0001] The utility model relates to a speed bump, in particular to a high-flexibility, heavy-pressure-resistant rubber speed bump. Background Art

[0002] A parking barrier is a common device used in indoor and outdoor parking lots to limit the position of vehicles when they are parked, preventing collisions between vehicles or between vehicles and walls and buildings.

[0003] At present, a Chinese patent with authorization announcement number CN209324096U discloses a wheel stopper, which includes a rectangular base and a step-shaped body. The base and the body are integrally formed, and the bottom surface of the body coincides with the top surface of the base. Main reflectors are provided on both the front and back sides of the body. A pre-warning portion is provided on the front side of the base for pre-contacting the wheel before the wheel contacts the body. A fixing hole is provided at each end of the top of the body, which passes through the body and the base.

[0004] By arranging a pre-warning part on the front of the base, when parking, the driver is assisted in confirming the distance between the wheel and the blocker body through the contact between the wheel and the pre-warning part, thereby facilitating the parking operation and preventing severe vehicle body vibration caused by rapid contact between the wheel and the body, thereby improving the safety of vehicle parking.

[0005] However, in real life, the wheels of the vehicle will press on the main reflector for a long time, which can easily cause damage to the main reflector and shorten its service life. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a highly flexible and heavy-pressure-resistant rubber speed bump to achieve the purpose of extending the service life.

[0007] In order to solve the above technical problems, the technical solution of the utility model is: a highly flexible and heavy-pressure-resistant rubber speed bump, comprising a reflector and a step-shaped body, a receiving cavity being opened inside the body, a receiving groove being opened on the side wall of the body, a support plate being hinged on the inner wall of the receiving groove, the reflector being fixed on the support plate, an elastic part being connected between the side of the support plate facing away from the reflector and the inner wall of the receiving cavity, the side of the support plate facing the reflector being connected to a resistance rod through a positioning structure, and the resistance rod being used to resist the wheel.

[0008] To implement the above technical solution, the interference rod is connected to the support plate through a positioning structure. When the wheel of the vehicle moves toward the interference rod, the wheel interferes with the interference rod, and the interference rod pushes the support plate to move, causing the support plate to move toward the accommodating cavity, so that the wheel does not contact the reflector, thereby extending the service life of the reflector; after the wheel is separated from the interference rod, the elastic force of the elastic member resets the support plate and the reflector.

[0009] As a preferred embodiment of the present utility model, the positioning structure includes a positioning hole, a positioning groove, and a positioning rod. The cross-section of the positioning hole is T-shaped and is formed on the support plate. The contact rod is rotatably connected in the positioning hole. The positioning groove is formed on the inner wall of the positioning hole. One end of the positioning rod is fixed to the end of the contact rod, and the positioning rod passes through the positioning groove.

[0010] To implement the above technical solution, connect the positioning rod and the contact rod, then place the contact rod in the positioning hole. At the same time, the positioning rod passes through the positioning groove. Rotate the contact rod to make the positioning rod in the positioning hole and misaligned with the positioning groove. At this time, the contact rod cannot be directly pulled out from the positioning hole. When the contact rod is damaged, rotate the contact rod. After the positioning rod corresponds to the positioning groove, the contact rod can be pulled out from the positioning hole to facilitate the replacement of the contact rod.

[0011] As a preferred embodiment of the present utility model, an elastic limiting structure is provided between the inner wall of the positioning hole and the positioning rod.

[0012] To implement the above technical solution, make the positioning rod not easy to rotate in the positioning hole and improve the stability of the contact rod.

[0013] As a preferred embodiment of the present utility model, the elastic limiting structure includes a limiting concave hole, a sliding sleeve, an elastic sheet, and a sliding column. The limiting concave hole is formed on the inner wall of the positioning hole. The sliding sleeve is threadedly connected to the end of the positioning rod away from the contact rod. The sliding column is slidably connected in the sliding sleeve, and the end of the sliding column is used to be embedded in the inner wall of the limiting concave hole. The elastic sheet is located in the sliding sleeve. One end of the elastic sheet abuts against the end of the positioning rod, and the other end of the elastic sheet abuts against the end of the sliding column.

[0014] To implement the above technical solution, rotate the contact rod to make the limiting concave hole correspond to the sliding column. Through the elastic force of the elastic sheet, make the sliding column abut tightly against the inner wall of the limiting concave hole to generate friction, so that the positioning rod is not easy to rotate in the positioning hole, thereby realizing the function of auxiliary limiting.

[0015] As a preferred embodiment of the present utility model, a support seat is fixedly connected to the end of the contact rod away from the support plate, and a friction ball is rotatably connected in the support seat.

[0016] To implement the above technical solution, the friction ball is rotatably connected in the support seat. When the friction ball abuts against the wheel, due to the rolling of the friction ball, wear is reduced, and the service life is further extended.

[0017] As a preferred embodiment of the present utility model, an elastic plate is fixedly connected to the inner wall of the accommodation cavity. Elastic grooves are formed on the elastic plate, and both sides of the elastic plate are fixedly connected to the inner wall of the accommodation cavity.

[0018] To implement the above technical solution, when the wheel presses on the body, the elastic groove deforms, so that the elastic plate has elastic force, making the body highly flexible.

[0019] As a preferred solution of the present utility model, a reinforcing plate is fixedly connected to the inner wall of the accommodation cavity. Both sides of the overtime plate are fixedly connected to the inner wall of the accommodation cavity, and the reinforcing plate and the elastic plate are arranged at intervals.

[0020] To implement the above technical solution, the reinforcing plate can improve the structural strength of the body, avoid the fracture of the elastic plate, and at the same time, improve the bearing capacity of the wheel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following further details the specific embodiments of the present utility model with reference to the drawings, so that the technical solutions of the present utility model are easier to understand and master.

[0028] A highly flexible and heavy-duty resistant rubber speed bump includes a reflective sheet 1 and a body 2 in the shape of a frustum of a pyramid. An accommodation cavity 21 is formed inside the body 2. A trapezoidal cross-section elastic plate 3 is fixedly connected to the inner wall of the accommodation cavity 21. An arc-shaped cross-section elastic groove 31 is formed on the elastic plate 3. Both sides of the elastic plate 3 are fixedly connected to the inner wall of the accommodation cavity 21.

[0029] A trapezoidal cross-section reinforcing plate 4 is fixedly connected to the inner wall of the accommodation cavity 21. Both sides of the overtime plate are fixedly connected to the inner wall of the accommodation cavity 21. The reinforcing plate 4 and the elastic plate 3 are arranged at intervals.

[0030] A receiving groove 51 is formed in the side wall of the main body 2, and the receiving groove 51 communicates with the receiving cavity 21. A support plate 52 is hinged to the upper edge of the inner wall of the receiving groove 51; the reflective sheet 1 is fixed to the support plate 52 by glue.

[0031] A resilient member 53 is fixedly connected between the side of the support plate 52 facing away from the reflective sheet 1 and the inner wall of the receiving cavity 21. The resilient member 53 is a spring. Through the elastic force of the resilient member 53, a continuous elastic force is generated on the support plate 52 in the direction close to the receiving groove 51. A contact rod 6 is connected to the side of the support plate 52 facing the reflective sheet 1 through a positioning structure 7, and the contact rod 6 is used to contact the wheel.

[0032] Applying pressure to the support plate 52, the support plate 52 flips along the hinge, and the resilient member 53 compresses to generate elastic force. After the pressure is released, the support plate 52 is reset by the elastic force of the resilient member 53.

[0033] The positioning structure 7 includes a positioning hole 71, a positioning groove 72, and a positioning rod 73. The cross-section of the positioning hole 71 is in a T shape and is formed in the support plate 52, and the contact rod 6 is rotatably connected in the positioning hole 71. The positioning groove 72 is formed in the inner wall of the positioning hole 71. One end of the positioning rod 73 is fixed to the end of the contact rod 6, and the positioning rod 73 passes through the positioning groove 72.

[0034] An elastic limiting structure 8 is provided between the inner wall of the positioning hole 71 and the positioning rod 73 to achieve auxiliary positioning between the positioning rod 73 and the inner wall of the positioning hole 71. The elastic limiting structure 8 includes a limiting concave hole 81, a sliding sleeve 82, a spring piece 83, and a sliding column 84. The limiting concave hole 81 is formed in the inner wall of the positioning hole 71, and the limiting concave hole 81 is not directly below the positioning groove 72. The sliding sleeve 82 is threadedly connected to the end of the positioning rod 73 away from the contact rod 6, and the cross-section of the sliding column 84 is in a T shape and is slidably connected in the sliding sleeve 82. The end of the sliding column 84 is hemispherical and is used to be embedded in the inner wall of the limiting concave hole 81. The spring piece 83 is made of a copper sheet and is located inside the sliding sleeve 82. One end of the spring piece 83 abuts against the end of the positioning rod 73, and the other end of the spring piece 83 abuts against the end of the sliding column 84.

[0035] Place the spring piece 83 at the end of the positioning rod 73, and make the sliding column 84 abut against the end of the spring piece 83. Thread the sliding sleeve 82 onto the end of the positioning rod 73 and fix the sliding sleeve 82 with glue. The spring piece 83 compresses to generate elastic force.

[0036] The positioning rod 73 is placed along the positioning groove 72 into the positioning hole 71. At this point, the slide post 84 abuts against the inner wall of the positioning hole 71, further compressing the spring piece 83. As the interference rod 6 drives the positioning rod 73 to rotate, when the slide post 84 aligns with the limiting recess 81, the elastic force of the spring piece 83 causes the slide post 84 to embed into the inner wall of the limiting recess 81, generating friction, thereby positioning the slide post 84 and limiting the rotation of the interference rod 6.

[0037] One end of the resistance rod 6 away from the support plate 52 is fixedly connected to a support seat 91 made of plastic. A friction ball 92 is embedded in the support seat 91 and is rotatably connected thereto. The outer wall of the friction ball 92 is coated with lubricating oil.

[0038] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
