Technical Field
[0001] This utility model relates to the field of road management technology, and in particular to a mobile flow restriction device for municipal road traffic management. Background Technology
[0002] Municipal road traffic management is an important component of urban operation management, aiming to ensure smooth and safe road traffic and improve the travel experience and quality of life for urban residents. Traffic control devices are commonly used in road traffic management to control or restrict traffic flow in specific areas, thereby effectively reducing road congestion, minimizing accident risks, and ensuring road safety.
[0003] A search of the Chinese patent "A Novel Municipal Road Traffic Restriction Device" with the publication number "CN220908220U" revealed that by installing self-locking casters on the base of the device, it can be easily moved as a whole. The addition of counterweights can effectively increase the stability of the device to resist wind forces and avoid safety hazards caused by the device tipping over. The support column, the base of the device, and the bidirectional telescopic rod can be freely disassembled, which also facilitates the separate transportation of the components.
[0004] While the use of self-locking casters and counterweights in the aforementioned application can increase the stability of the equipment, the small contact area between the casters and the ground can cause the equipment to easily shift during use, thus affecting its stability.
[0005] Therefore, a mobile traffic control device for municipal road traffic management is proposed to solve the above problems. Summary of the Invention
[0006] The purpose of this utility model is to provide a mobile flow restriction device for municipal road traffic management in order to solve the above-mentioned problems. It improves the problem that the small contact area between the casters and the ground can cause the device to easily deviate during use, thus affecting the stability of the device during use.
[0007] This utility model achieves the above-mentioned objective through the following technical solution: a movable flow restriction device for municipal road traffic management, comprising: a fixed base, with universal wheels provided at the four corners of the bottom end of the fixed base, a support column installed at the top end of the fixed base, a movable column slidably connected to the inner wall of the support column, a fixed rod installed on one side of the movable column, and a movable rod slidably connected to the inner wall of the fixed rod.
[0008] The support mechanism includes two mounting rods fixedly connected to the bottom of a fixed rod. A slider is slidably connected to the surface of the mounting rod. A hinge seat is installed at the bottom of the slider. A telescopic rod is hinged to one side of the hinge seat. A support plate is hinged to the bottom of the telescopic rod. A fixing component is provided on one side of the slider.
[0009] Preferably, the fixing assembly includes a mounting plate fixedly connected to one side of the slider. A lead screw is rotatably connected to the inner wall of the mounting plate, and a sliding plate is threaded onto the surface of the lead screw. A locking rod is fixedly connected to the other end of the sliding plate. Multiple annularly distributed locking holes are provided at one end of the rotating shaft of the telescopic rod. This facilitates fixing the telescopic rod after angle adjustment, enhances the stability of the telescopic rod during support, and, with the help of multiple locking holes, allows the telescopic rod to be tilted at different angles as needed during use, increasing the practicality of the device.
[0010] Preferably, a movable plate is slidably connected to the inner wall of the fixed base, and the top ends of the plurality of casters are fixedly connected to the bottom end of the movable plate. An electric push rod is fixedly connected to the top end of the fixed base, and the bottom end of the electric push rod passes through the fixed base and is fixedly connected to the top end of the movable plate. This facilitates the retraction of the casters into the fixed base during use, increasing the contact area between the device and the ground when it is in fixed use.
[0011] Preferably, one side of the mounting rod has multiple evenly distributed threaded holes, and the inner wall of the slider is threaded with a threaded rod. This facilitates the adjustment and fixation of the distance between the two telescopic rods according to the width of the flow restriction and interception by the fixed rod and the moving rod, improving the practicality of the device during use.
[0012] Preferably, the bottom end of the support plate has multiple evenly distributed grooves, which are arranged at an angle. This increases the friction between the support plate and the ground, thereby enhancing the stability of the support plate during operation.
[0013] Preferably, the inner walls of each of the multiple threaded holes are fitted with sealing plugs, which are rubber components. This helps to protect the multiple threaded holes, prevent impurities from remaining inside the threaded holes, and thus ensure the stability of the connection between the threaded rod and the threaded hole.
[0014] Preferably, corrugated sleeves are fixedly connected to both sides of the slide plate, and the other ends of the two corrugated sleeves are respectively fixedly connected to the inner wall of the mounting plate and one side of the slider. This helps to protect the lead screw and prevent impurities from remaining on the lead screw during use, thereby ensuring the stability of the connection between the lead screw and the slide plate during use.
[0015] The beneficial effects of this utility model are:
[0016] 1. Based on the width of the fixed and movable rods during interception, the device retracts the casters into the fixed base when performing flow restriction operations, which helps to increase the contact area between the device and the ground when it is fixed. Furthermore, the support mechanism, by rotating the two telescopic rods in opposite directions and supporting the support plate with the ground, helps to form a triangular support between the two telescopic rods and the horizontal plane to reinforce the support column. In addition, the support plate increases the contact area between the device and the ground when it is fixed, thereby enhancing the stability of the device and keeping it stable when performing flow restriction operations.
[0017] 2. The multiple threaded holes and threaded rods allow for adjustment and fixation of the distance between the two telescopic rods based on the width of the fixed rod and the moving rod during flow restriction and interception, thus improving the practicality of the device.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] In practical implementation: such as Figure 1-5 As shown, a movable flow restriction device for municipal road traffic management includes: a fixed base 100, with casters 110 at each of the four corners of the bottom end of the fixed base 100; a support column 200 installed at the top of the fixed base 100; a movable column 300 slidably connected to the inner wall of the support column 200; a fixed rod 400 installed on one side of the movable column 300; and a movable rod 410 slidably connected to the inner wall of the fixed rod 400; a support mechanism 500, including two mounting rods 510 fixedly connected to the bottom end of the fixed rod 400; a slider 520 slidably connected to the surface of the mounting rod 510; a hinge seat 530 installed at the bottom end of the slider 520; a telescopic rod 540 hinged to one side of the hinge seat 530; a support plate 550 hinged to the bottom end of the telescopic rod 540; and a fixing component 560 provided on one side of the slider 520.
[0026] In this embodiment, the support column 200 is installed on the fixed seat 100 by bolts. The telescopic rod 540 includes a fixed frame and a support rod. The surface of the support rod is slidably connected to the inner wall of the fixed frame. The top of the fixed frame is hinged to the hinge seat 530, and the bottom of the support rod is hinged to the support plate 550. During use, the hinge between the support plate 550 and the support rod is fixed by bolts. Multiple screw holes are provided on one side of the support rod. A bolt is threaded to the lower end of one side of the fixed frame. The fixed frame and the support rod are fixed by bolts and screw holes.
[0027] The fixed rod 400 is internally threaded with bolts, and the front end of the movable rod 410 has a threaded hole. The fixed rod 400 and the movable rod 410 are installed using bolts and threaded holes. Multiple evenly distributed threaded holes are provided on one side of the movable rod 410. Bolts are threaded to the upper inner end of the support column 200 and one side of the inner wall of the fixed rod 400. During use, the movable column 300 is pulled vertically to adjust the height. After height adjustment, the movable column 300 and support column 200 are installed using bolts and threaded holes. The movable rod 410 is then pulled horizontally to adjust the overall length of the fixed rod 400 and the movable rod 410. After length adjustment, the movable rod 410 and the fixed rod 400 are fixed using bolts and threaded holes.
[0028] The bottom end of the hinge seat 530 is threaded with a bolt, and the bottom end of the slider 520 is provided with a screw hole. The hinge seat 530 and the slider 520 are installed by bolts and screw holes. The device can be disassembled by bolts during transportation, which facilitates the transportation of the device.
[0029] It should be noted that after the device is adjusted, the exposed screw holes of the moving column 300, the moving rod 410, and the support rod are protected by the rubber protective plugs during use, thereby preventing dust and impurities from entering the screw holes.
[0030] like Figure 2 and Figure 4 As shown, the fixing assembly 560 includes a mounting plate 561 fixedly connected to one side of the slider 520. A lead screw 562 is rotatably connected to the inner wall of the mounting plate 561. A sliding plate 563 is threadedly connected to the surface of the lead screw 562. A locking rod 564 is fixedly connected to the other end of the sliding plate 563. A plurality of locking holes 565 distributed in a ring are opened at one end of the rotating shaft of the telescopic rod 540.
[0031] In this embodiment, the diameter of the locking rod 564 matches the diameter of the locking hole 565. After the hinge seat 530 and the slider 520 are installed, when the telescopic rod 540 rotates, the rotation path of the locking rod 564 coincides with that of the multiple locking holes 565. The opening of the locking hole 565 is trumpet-shaped, and the end of the locking rod 564 is curved into an arc shape.
[0032] A round rod is fixedly connected to one side of the slider 520, and the inner wall of the slide plate 563 is slidably connected to the surface of the round rod. The round rod limits the movement path of the slide plate 563.
[0033] like Figure 2 As shown, a movable plate 120 is slidably connected to the inner wall of the fixed base 100, and the top ends of multiple casters 110 are fixedly connected to the bottom end of the movable plate 120. An electric push rod 130 is fixedly connected to the top end of the fixed base 100, and the bottom end of the electric push rod 130 passes through the fixed base 100 and is fixedly connected to the top end of the movable plate 120.
[0034] In this embodiment, the bottom end of the fixed base 100 is provided with a through groove that matches the universal wheel 110. In the initial state, the universal wheel 110 is in contact with the ground, and the bottom ends of the two support plates 550 do not affect the electric push rod 130.
[0035] like Figure 4 As shown, a plurality of evenly distributed threaded holes 511 are provided on one side of the mounting rod 510, and a threaded rod 521 is threadedly connected to the inner wall of the slider 520. Sealing plugs 512, which are rubber components, are installed on the inner walls of the plurality of threaded holes 511.
[0036] In this embodiment, in the initial state, the threaded rod 521 is threadedly connected to one of the threaded holes 511, fixing the slider 520 in a suitable position, and the sealing plug 512 seals the other threaded holes 511, thereby protecting the threaded holes 511.
[0037] like Figure 5As shown, the bottom end of the support plate 550 has a plurality of evenly distributed grooves 551, which are inclined.
[0038] In this embodiment, when the support plate 550 is in contact with the ground, the groove 551 increases the friction between the support plate 550 and the ground.
[0039] like Figure 4 As shown, corrugated sleeves 566 are fixedly connected to both sides of the slide plate 563, and the other ends of the two corrugated sleeves 566 are fixedly connected to the inner wall of the mounting plate 561 and one side of the slider 520, respectively.
[0040] In this embodiment, the corrugated sleeve 566 is a rubber component, and the lead screw 562 is located inside the corrugated sleeve 566. When the slide plate 563 moves, it will drive the corrugated sleeve 566 in the corresponding direction to automatically extend and retract.
[0041] In use, this utility model is assembled by bolts to connect the support column 200 to the fixed seat 100, the fixed rod 400 to the moving rod 410, and the hinge seat 530 to the slider 520. After assembly, the device is moved to the desired position using the casters 110. The overall height of the moving column 300 and the support column 200, and the overall length of the moving rod 410 and the fixed rod 400 are adjusted according to actual usage needs. After adjustment, the device is fixed using bolts and screw holes. After fixing, the electric push rod 130 is activated, causing its telescopic end to move the moving plate 120 upward. This causes the moving plate 120 to move the casters 110 into the inner side of the fixed seat 100, and the bottom of the fixed seat 100 contacts the ground. After this operation, the two sliders 520 are moved horizontally in opposite directions, causing the corresponding hinge seat 530 and telescopic rod 540 to move synchronously. The two telescopic rods 540 are moved to a suitable position according to the overall length of the fixed rod 400 and the moving rod 410. The slider 520 is fixed using the threaded rod 521 and the threaded hole 511. After fixing, the operator rotates the two telescopic rods 540 in opposite directions to create an angle between the two telescopic rods 540 and the support column 200. After rotating to a certain angle, the length of the telescopic rods 540 is adjusted so that the bottom end of the support plate 550 contacts the ground. At this time, the operator rotates the screw 562 to move the slide plate 563, so that the slide plate 563 drives the locking rod 564 into the corresponding locking hole 565, thereby fixing the telescopic rod 540 and the hinge seat 530 and ensuring the stability of the telescopic rod 540 when supported. At this time, the two telescopic rods 540 form a triangular support with the horizontal plane to reinforce the support column 200, thereby keeping the device stable when performing flow-limiting operations.
[0042] It should be noted that the electric actuator 130 and other devices mentioned above are all relatively mature devices with existing technologies. The specific model can be selected according to actual needs. The electric actuator 130 can be powered by a built-in power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.
[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
