[0003] Publication number: CN 219912511U discloses a vehicle-road cooperative roadside equipment fixing device. However, in the implementation process of this solution, it is first necessary to manually pull out the telescopic pole and then rotate the screw sleeve to fix the height of the detector. This cannot be done by a single person and is quite inconvenient. Therefore, a vehicle-road cooperative roadside equipment fixing device is proposed. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a vehicle-road cooperative roadside equipment fixing device to address the shortcomings of the prior art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A vehicle-road cooperative roadside equipment fixing device includes a base, a fixing sleeve is provided on the base, an installation rod is slidably connected to the inner wall of the fixing sleeve, and the upper end of the installation rod extends out of the upper port of the fixing sleeve. A storage cavity is provided on the surface of the installation rod, a cover plate is rotatably provided in the storage cavity, and the cover plate can be rotated to extend out of the storage cavity or stored in the storage cavity. A support plate is fixedly connected to the surface of the cover plate, a detector is provided on the surface of the support plate, and a driving mechanism is provided in the fixing sleeve. The driving mechanism is pulsatorically connected to the installation rod and can drive the installation rod to move up and down in the fixing sleeve.

[0006] The beneficial effects of this utility model are as follows: The vehicle-road cooperative roadside equipment fixing device of this utility model has a mounting rod that is slidably set in the fixing platform and is driven by the driving mechanism. In this way, the mounting rod can be driven to move up and down in the fixing sleeve by the driving mechanism. At the same time, a cover plate is rotatably set in the storage cavity of the mounting rod, which can be easily rotated to extend out of the storage cavity for detection by the detector on it, or rotated back into the storage cavity, which is very convenient.

[0007] Based on the above technical solution, the present invention can be further improved as follows:

[0008] Further: The driving mechanism includes a motor, which is mounted on the base and located inside the fixed sleeve. A threaded rod is vertically arranged inside the fixed sleeve. The lower end of the threaded rod is rotatably connected to the base, and the upper end of the threaded rod extends into the mounting rod and is threadedly connected to the mounting rod. A second gear is provided on both the output end of the motor and the mounting rod, and the two second gears mesh. The motor can drive the second gears to rotate the threaded rod, thereby driving the mounting rod to move up and down within the fixed sleeve.

[0009] The beneficial effect of the above-mentioned further solution is that the motor drives the second gear to rotate the threaded rod, and the threaded rod drives the mounting rod to rotate, thereby realizing the automatic lifting and lowering movement of the mounting rod within the fixed sleeve, which is very convenient.

[0010] Furthermore, the mounting rod is provided with limiting grooves on both sides of the storage cavity, and limiting strips are fixedly connected to both sides of the inner wall of the fixing sleeve, the limiting strips are inserted into the limiting grooves and slidably connected to the inner wall of the limiting grooves.

[0011] The beneficial effect of the above-mentioned further solution is that by setting the limiting groove and limiting bar, the mounting rod can slide up and down stably and reliably within the fixed sleeve, ensuring the stability of the entire device.

[0012] Furthermore, the vehicle-road cooperative roadside equipment fixing device also includes a transmission component, which is disposed in the limiting groove. When the mounting rod moves upward within the fixing sleeve, the transmission component can move to be connected to the support plate and drive the support plate to rotate and gradually unfold.

[0013] The beneficial effect of the above-mentioned further solution is that by setting the transmission component, the support plate and the detector on it can be easily rotated when the mounting rod moves upward in the fixed sleeve. Thus, the entire device only needs to realize the automatic lifting and lowering of the mounting rod and the automatic unfolding or retraction of the support plate under the drive of the motor. There is no need for manual lifting and screwing. It can be operated by a single person, which is simple and convenient.

[0014] Further: The transmission assembly includes two sprockets, which are arranged vertically at intervals on the inner wall of the limiting groove. The two sprockets are connected by a chain meshing. A first gear is coaxially connected to the lower sprocket. A rack matching the first gear is fixedly connected to the inner wall of the limiting strip. When the mounting rod rises in the fixed sleeve, the first gear can mesh with or disengage from the rack.

[0015] The beneficial effects of the above-mentioned further solution are: by setting the sprocket and cooperating with the chain to achieve up-and-down linkage, and by setting a rack on the inner wall of the limiting strip, when the mounting rod rises in the fixed sleeve until the first gear meshes with the rack, the limiting strip rises and drives the first gear and sprocket to rotate through the rack, thereby driving the support plate to automatically unfold or retract, realizing the automatic lifting and lowering of the mounting rod and the automatic unfolding or retracting of the support plate in a synchronous linkage, which is very convenient.

[0016] Furthermore, the vehicle-road cooperative roadside equipment fixing device further includes a snap-fit ​​component, which is disposed on the side wall of the mounting rod and located between the two limiting strips. The snap-fit ​​component can snap into the first gear and restrict the rotation of the first gear.

[0017] The beneficial effect of the above-mentioned further solution is that by setting the snap-fit ​​component, the first gear can be easily snapped and limited after the support plate is unfolded to a set angle, thereby ensuring the stability of the support plate.

[0018] Further: The locking assembly includes a sliding rod, a locking block, and an operating rod. The sliding rod is disposed between the two limiting strips, and both ends of the sliding rod are slidably connected to the inner sidewalls of the limiting strips. The locking block is disposed on the surface of the sliding rod. The middle part of the first gear is provided with a hole for locking the locking block. The fixed sleeve is provided with a strip-shaped hole for the operating rod to extend out. One end of the operating rod is connected to the locking block, and the other end of the operating rod passes through and extends out of the fixed sleeve. The operating rod can drive the locking block to slide up and down along the inner sidewall of the limiting strip until the locking block is completely aligned with the hole, and the operating rod can drive the locking block to lock into the hole.

[0019] The beneficial effect of the above-mentioned further solution is that by setting the sliding rod, the sliding rod and the locking block can be moved up and down together by the operating rod, so that when the locking block is fully aligned with the hole, the locking block can be locked into the hole, thereby locking the first gear and ensuring the stability of the entire device during detection.

[0020] Further: Movable blocks are slidably arranged on both sides of the upper part of the inner wall of the storage cavity, and the movable blocks are located between the support plate and the inner wall of the corresponding side of the storage cavity. Rotating rods are arranged on both sides of the support plate. One end of the rotating rod is fixedly connected to the corresponding side wall of the support plate, and the other end of the rotating rod is rotatably connected to the corresponding movable block. A torsion spring is sleeved on the surface of the rotating rod. The torsion spring is located between the support plate and the corresponding movable block. The two ends of the torsion spring are respectively connected and fixed to the surface of the rotating rod and the movable block.

[0021] The beneficial effects of the above-mentioned further solution are as follows: by setting the movable block and connecting it to the corresponding side of the support plate through the rotating rod, the support plate can be supported, and the movable block can adaptively slide on the inner wall of the storage cavity while the support plate rotates. At the same time, the torsion spring can provide assistance by utilizing the restoring force when unfolding the support plate, which is very convenient.

[0022] Furthermore, both inner walls of the storage cavity are rotatably connected to take-up rollers, which are coaxially connected to the corresponding sprockets located above. The take-up rollers are connected to the end of the cover plate that extends out of the storage cavity via a traction rope.

[0023] The beneficial effect of the above-mentioned further solution is that by setting the take-up roller and the traction rope, the take-up roller can be driven to rotate when the sprocket rotates, and the support plate can be automatically unfolded or folded and stored by the traction rope, so that the lifting and lowering of the mounting rod is synchronized with the automatic unfolding or retraction of the support plate.

[0024] Further: The base has a downward-opening groove in the middle of its bottom wall. A fixed rod is vertically connected to the inner top wall of the groove. A movable block with a conical upper surface is slidably connected to the lower end of the fixed rod. Multiple lugs that can extend out of the edge of the base are slidably connected to the bottom of the base. A sliding rod is fixedly connected to one end of the lug near the movable block. The sliding rod passes through the side wall of the groove and can abut against the surface of the movable block. A spring is movably sleeved on the surface of the sliding rod. The spring is located between the outer wall of the groove and the lug, and both ends of the spring are fixedly connected to the lug and the outer wall of the groove, respectively. A fixing part for fixing to an external carrier is provided on the lug away from the movable block.

[0025] The beneficial effects of the above-mentioned further solution are as follows: by setting the fixed rod and the movable block, it can be convenient to provide support during use and increase the friction between the fixed rod and the external carrier. At the same time, when the movable block is driven to move upward by the gravity of the entire device, the conical surface of the movable block drives the sliding rod to move. The sliding rod drives the end of the lug away from the movable block to extend out of the edge of the base, so that the entire base can be fixed to the external carrier by the fixing part on the lug, thus ensuring the stability of the entire device during operation.

[0035] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0036] like Figures 1 to 7 As shown, a vehicle-road cooperative roadside equipment fixing device includes a base 2, a fixing sleeve 1 on the base 2, an installation rod 4 slidably connected to the inner wall of the fixing sleeve 1, and the upper end of the installation rod 4 extending out of the upper port of the fixing sleeve 1. A storage cavity 5 is provided on the surface of the installation rod 4, and a cover plate 11 is rotatably disposed in the storage cavity 5. The cover plate 11 can be rotated to extend out of the storage cavity 5 or stored in the storage cavity 5. A support plate 9 is fixedly connected to the surface of the cover plate 11, and a detector 12 is provided on the surface of the support plate 9. A driving mechanism is provided in the fixing sleeve 1, and the driving mechanism is pulsatorically connected to the installation rod 4 and can drive the installation rod 4 to move up and down within the fixing sleeve 1.

[0037] The vehicle-road cooperative roadside equipment fixing device of this utility model has a mounting rod 4 slidably set in the fixing platform 1 and driven by the driving mechanism. The mounting rod 4 can be driven to move up and down in the fixing sleeve 1 by the driving mechanism. At the same time, a cover plate 11 is rotatably set in the storage cavity 5 of the mounting rod 4. This allows it to be easily rotated to extend out of the storage cavity 5 for the detector on it to perform detection, or rotated back into the storage cavity 5, which is very convenient.

[0038] In one or more embodiments of this utility model, the driving mechanism includes a motor 18, which is mounted on the base 2 and located inside the fixed sleeve 1. A threaded rod 20 is vertically arranged inside the fixed sleeve 1. The lower end of the threaded rod 20 is rotatably connected to the base 2, and the upper end of the threaded rod 20 extends into the mounting rod 4 and is threadedly connected to the mounting rod 4. A second gear 19 is provided on both the output end of the motor 18 and the mounting rod 4, and the two second gears 19 mesh. The motor 18 can drive the second gears 19 to rotate the threaded rod 20, thereby driving the mounting rod 4 to move up and down within the fixed sleeve 1. By having the motor 18 drive the second gears 19 to rotate the threaded rod 20, and the threaded rod 20 drives the mounting rod 4 to rotate, the automatic up and down movement of the mounting rod 4 within the fixed sleeve 1 is achieved, which is very convenient.

[0039] In one or more embodiments of this utility model, the mounting rod 4 is provided with limiting grooves 6 on both sides of the receiving cavity 5, and limiting strips 13 are respectively fixedly connected to both sides of the inner wall of the fixing sleeve 1. The limiting strips 13 are inserted into the limiting grooves 6 and slidably connected to the inner wall of the limiting grooves 6. By setting the limiting grooves 6 and limiting strips 13, the mounting rod 4 can slide up and down stably and reliably within the fixing sleeve 1, and the movement of the mounting rod 4 can be guided and restricted, preventing the mounting rod 4 from rotating with the rotation of the threaded rod 20, ensuring the smooth operation of the device and the stability of the entire device.

[0040] Optionally, in one or more embodiments of this utility model, the vehicle-road cooperative roadside equipment fixing device further includes a transmission component. The transmission component is disposed within the limiting groove 6, and when the mounting rod 4 moves upward within the fixing sleeve 1, the transmission component can move to a transmission connection with the support plate 9, and drive the support plate 9 to rotate and gradually unfold. By setting the transmission component, it is convenient to drive the support plate 9 and the detector 12 thereon to rotate when the mounting rod 4 moves upward within the fixing sleeve 1. Thus, the entire device only needs to be driven by the motor 18 to achieve automatic lifting and lowering of the mounting rod 4 and automatic unfolding or retraction of the support plate 9, without the need for manual lifting and screwing. It can be operated by a single person, making the operation simple and convenient.

[0041] Specifically, in one or more embodiments of this utility model, the transmission assembly includes two sprockets 8, which are spaced vertically on the inner wall of the limiting groove 6. The two sprockets 8 are connected by a chain 7. A first gear 14 is coaxially connected to the lower sprocket 8. A rack 17 matching the first gear 14 is fixedly connected to the inner wall of the limiting strip 13. When the mounting rod 4 rises within the fixed sleeve 1, the first gear 14 can engage or disengage with the rack 17. By setting the sprockets 8 and cooperating with the chain 7, vertical linkage is achieved. By setting the rack 17 on the inner wall of the limiting strip 13, when the mounting rod 4 rises within the fixed sleeve 1 until the first gear 14 engages with the rack 17, the limiting strip 13 rises and drives the first gear 14 and sprocket 8 to rotate through the rack 17, thereby automatically unfolding or retracting the support plate 9. This achieves synchronous linkage between the automatic lifting and lowering of the mounting rod 4 and the automatic unfolding or retracting of the support plate 9, which is very convenient.

[0042] Optionally, in one or more embodiments of this utility model, the vehicle-road cooperative roadside equipment fixing device further includes a snap-fit ​​component. The snap-fit ​​component is disposed on the side wall of the mounting rod 4 and located between the two limiting strips 13. The snap-fit ​​component can snap with the first gear 14 and restrict the rotation of the first gear 14. By providing the snap-fit ​​component, the first gear 14 can be easily snapped and limited after the support plate 9 is unfolded to a set angle, thereby ensuring the stability of the support plate 9.

[0043] Specifically, in one or more embodiments of this utility model, the snap-fit ​​assembly includes a sliding rod 16, a snap-fit ​​block 15, and an operating rod 28. The sliding rod 16 is disposed between the two limiting strips 13, and both ends of the sliding rod 16 are slidably connected to the inner sidewalls of the limiting strips 13. The snap-fit ​​block 15 is disposed on the surface of the sliding rod 16. The middle part of the first gear 14 is provided with a hole for snapping into the snap-fit ​​block 15. The fixed sleeve 1 is provided with a strip-shaped hole for the operating rod 28 to extend out. One end of the operating rod 28 is connected to the snap-fit ​​block 15, and the other end of the operating rod 28 passes through and extends out of the fixed sleeve 1. The operating rod 28 can drive the snap-fit ​​block 15 to slide up and down along the inner sidewall of the limiting strip 13 until the snap-fit ​​block 15 is completely aligned with the hole, and the operating rod 28 can drive the snap-fit ​​block 15 to snap into the hole. By setting the sliding rod 16, the operating rod 28 can drive the sliding rod 16 and the locking block 15 to move up and down together, so that when the locking block 15 is fully aligned with the hole, it can be locked into the hole, thereby locking the first gear 14 and ensuring the stability of the entire device during testing; the other end of the operating rod 28 passes through and extends out of the fixed sleeve 1, and cooperates with the strip hole to facilitate the operation of the locking block 15 by the operator.

[0044] In one or more embodiments of this utility model, movable blocks 25 are slidably arranged on both sides of the upper part of the inner wall of the storage cavity 5, and the movable blocks 25 are located between the support plate 9 and the inner wall of the corresponding side of the storage cavity 5. Rotating rods 26 are respectively arranged on both sides of the support plate 9. One end of the rotating rod 26 is fixedly connected to the corresponding side wall of the support plate 9, and the other end of the rotating rod 26 is rotatably connected to the corresponding movable block 25. A torsion spring 27 is sleeved on the surface of the rotating rod 26, and the torsion spring 27 is located between the support plate 9 and the corresponding movable block 25. Both ends of the torsion spring 27 are respectively connected and fixed to the surface of the rotating rod 26 and the movable block 25. By setting the movable blocks 25 and connecting them to the corresponding side of the support plate 9 via the rotating rods 26, the support plate 9 can be supported, allowing the movable blocks 25 to adaptively slide on the inner wall of the storage cavity 5 while the support plate 9 rotates. Simultaneously, the torsion spring 27 provides assistance by utilizing restoring force when the support plate 9 is unfolded, which is very convenient.

[0045] In practice, when the support plate 9 is stored in the storage cavity 5, the torsion spring 27 is in a torsional state. Therefore, when the support plate 9 is unfolded, a certain amount of power can be provided by the restoring force of the torsion spring 27.

[0046] It should be noted that, in practice, the side of the movable block 25 near the inner wall of the receiving cavity 5 of the mounting rod 4 is spherical, which reduces the friction when the movable block 25 slides in the mounting rod 4 and improves the smoothness of the device operation.

[0047] In one or more embodiments of this utility model, take-up rollers 24 are rotatably connected to the inner walls of both sides of the storage cavity 5. Each take-up roller 24 is coaxially connected to a corresponding sprocket 8 located above it. The take-up roller 24 is connected to one end of the cover plate 11 that extends out of the storage cavity 5 via a traction rope 10. By setting the take-up roller 24 and the traction rope 10, the take-up roller 24 can be rotated when the sprocket 8 rotates, and the support plate 9 can be automatically unfolded or folded for storage via the traction rope 10, thus achieving synchronous linkage between the lifting and lowering of the mounting rod 4 and the automatic unfolding or retraction of the support plate 9.

[0048] In one or more embodiments of this utility model, a downward-opening groove is provided in the middle of the bottom wall of the base 2. A fixing rod 23 is vertically connected to the inner top wall of the groove. A movable block 21 with a conical upper surface is slidably connected to the lower end of the fixing rod 23. A plurality of lugs 3 that can extend out of the edge of the base 2 are slidably connected to the bottom of the base 2. A sliding rod 29 is fixedly connected to one end of the lug 3 near the movable block 21. The sliding rod 29 passes through the side wall of the groove and can abut against the surface of the movable block 21. A spring 22 is movably sleeved on the surface of the sliding rod 29. The spring 22 is located between the outer wall of the groove and the lug 3, and the two ends of the spring 22 are fixedly connected to the lug 3 and the outer wall of the groove, respectively. A fixing part for fixing to an external carrier is provided on the lug 3 away from the movable block 21. By setting the fixed rod 23 and the movable block 21, it is convenient to provide support during use and increase the friction between the device and the external carrier. At the same time, when the movable block 21 is driven to move upward by the gravity of the entire device, the conical surface of the movable block 21 drives the slide rod 29 to move. The slide rod 29 drives the lug 3 to extend from the edge of the base 2 away from the movable block 21, so that the entire base 2 can be fixed to the external carrier by the fixing part on the lug 3, thus ensuring the stability of the entire device during operation.

[0049] In practice, the fixing part can be a circular through hole at the end of the lug 3, or it can be an open semi-circular through hole. In practice, it can be flexibly set according to needs.

[0050] Preferably, in an embodiment of the present invention, a plurality of the lugs 3 are arranged circumferentially at equal intervals at the bottom of the base 2, so that by means of the lugs 3, the operator can install the device on the ground by passing bolts through the lugs 3. The two ends of the spring 22 are respectively fixedly connected to the surface of the lugs 3 and the interior of the base 2 to reset the lugs 3.

[0051] When in use, the device is erected on the ground, and under the weight of the entire device, the movable block 21 retracts into the base 2, so that the conical surface of the movable block 21 pushes the slide rod 29, thereby driving the lug 3 to gradually protrude from the surface of the base 2 and stretching the spring 22. At this time, the operator can use bolts to pass through the fixing part of the lug 3 to install the device on the ground.

[0052] Then, the operator can start the motor 18, which drives the threaded rod 20 to rotate through the meshing connection of the two second gears 19. This causes the mounting rod 4 to gradually rise within the fixed sleeve 1. As the mounting rod 4 rises, the first gear 14 gradually contacts and meshes with the rack 17. At this point, the support plate 9 is completely exposed outside the fixed sleeve 1. Because the first gear 14 and the rack 17 are meshed, the first gear 14 rotates as the mounting rod 4 rises, driving the sprocket 8, which is coaxially connected to the first gear 14, to rotate. This, in turn, drives the upper sprocket 8 to rotate via the chain 7, thereby driving the take-up roller 2. Rotation 4 causes the take-up roller 24 to relax the traction rope 10. Under the elastic force of the torsion spring 27, the support plate 9 gradually unfolds and remains perpendicular to the mounting rod 4. At this time, the first gear 14 separates from the rack 17 and contacts the locking block 15. Then, by pulling the operating rod 28, the locking block 15 is moved. After the hole on the first gear 14 corresponds with the locking block 15, pushing the operating rod 28 will insert the locking block 15 into the first gear 14, thereby restricting the rotation of the first gear 14 and thus restricting the rotation of the support plate 9, ensuring the stability of the detector 12 during detection.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
