Description

Technical Field

[0001] This utility model belongs to the technical field of traffic signal equipment, and specifically relates to a safe temporary traffic signal control device. Background Technology

[0002] Currently, Chinese utility model patent CN220873132U discloses a traffic signal control device. This patent uses a limiting pin inserted into the housing to limit and fix the gear. Because the limiting pin is inserted from the side, it is difficult to engage with the gear slot; the pin easily abuts against the gear teeth, preventing insertion. Furthermore, after insertion, the weight of the traffic light is entirely concentrated on the limiting pin, making it difficult to remove and inconvenient for practical use. Additionally, when the traffic light is laid down, it protrudes from the base and is easily damaged by impact, offering no protection and resulting in poor safety. Utility Model Content

[0003] The purpose of this utility model is to provide a safe temporary traffic signal control device, which has the advantages of facilitating the locking and unlocking of the traffic light height adjustment and protecting the folded traffic lights.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a safe temporary traffic signal control device, including a support base, a support cylinder rotatably connected inside the support base, a lifting rod slidably connected inside the support cylinder, a signal light body bolted to the top of the lifting rod, a linear rack bolted to one side of the lifting rod, a disc gear meshing with the linear rack rotatably connected inside the support cylinder near the linear rack, a limiting tooth plate slidably connected to the support cylinder on the side of the disc gear away from the linear rack, a limiting bolt threadedly connected to the support cylinder on the side of the limiting tooth plate away from the disc gear, and a crank handle bolted to the disc gear rotatably connected to the outside of the support cylinder.

[0005] The above technical solution utilizes a rotating disc gear that meshes with a linear rack to adjust the height of the traffic light body. A limiting bolt is then twisted to engage the protruding teeth on one side of the limiting gear plate within the grooves of the disc gear, securing and limiting the disc gear. This not only allows for height control and adjustment of the traffic signal device but also facilitates locking and releasing the adjusted height, improving practicality. During the lowering process, the sliding seat moves away from the support base, allowing the traffic light body to lie within its placement slot after being laid down, preventing it from protruding. This protects the traffic light body, reduces the risk of collision damage, and enhances safety.

[0006] The present invention is further configured as follows: a sliding seat is provided on the side of the support base away from the limiting bolt; the top of the sliding seat is provided with a placement groove for use with the main body of the signal light; a conical gear plate rotatably connected to the support base is bolted to one side of the bottom of the support cylinder; a conical gear plate rotatably connected to the support base is engaged on the side of the conical gear plate away from the sliding seat; a screw threaded to the sliding seat is rotatably connected inside the support base; a synchronous pulley is bolted to the end of the screw and the conical gear away from the sliding seat; and a synchronous belt is driven sleeved on the surface of the synchronous pulley.

[0007] By adopting the above technical solution, the main body of the traffic light is prevented from protruding to the outside, thereby protecting the main body of the traffic light, reducing the risk of collision damage, and improving safety.

[0008] The present invention is further configured such that: a return spring bolted to the support cylinder is welded to the side of the limiting tooth plate away from the disc gear, and the return spring is sleeved on the surface of the limiting bolt.

[0009] By adopting the above technical solution, the rebound force of the reset spring can drive the limit tooth plate to slide away from the disc gear, thereby facilitating the lowering of the lifting rod after the limit bolt is torn and reset.

[0010] The present invention is further configured such that: universal wheels are bolted to the sides of the bottom of the support base and the sliding base that are far apart from each other, and a locking device is bolted to one side of the universal wheel.

[0011] The above technical solution facilitates the repositioning of traffic signal devices. Additionally, locking devices can be used to secure the casters, thereby limiting and fixing the traffic signal device in place.

[0012] The present invention is further configured such that a protective pad for use with the signal light body is adhered to the bottom of the inner cavity of the placement slot.

[0013] By adopting the above technical solution, the main body of the traffic light is placed inside the placement slot for buffer protection, which improves its quality and prevents it from being damaged by bumps.

[0014] The present invention is further configured such that: a limiting plate is provided on the top of the sliding seat, and both sides of the limiting plate are slidably connected with fixing bolts that are threadedly connected to the sliding seat.

[0015] By adopting the above technical solution, the limiting plate is bolted and fixed to the top of the sliding seat by tightening the fixing bolts, thereby reinforcing and limiting the main body of the signal light and improving safety.

[0016] The present invention is further configured such that: a fixing plate is welded to the side of the support seat and the sliding seat that are close to each other, and a connecting bolt is bolted through the inside of the fixing plate.

[0017] By using the above technical solution, the two fixing plates are bolted together by tightening the connecting bolts, so that the support base and the sliding base are fixed together, thus limiting and fixing the support tube whether it is standing up or lying down.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. The height of the traffic light is adjusted by rotating a disc gear that meshes with a linear rack. The limiting bolt is then twisted to engage the protruding teeth on one side of the limiting gear plate with the grooves of the disc gear, thus securing and limiting the disc gear. This not only controls and adjusts the height of the traffic signal device but also facilitates securing and releasing the adjusted height, improving its practicality.

[0020] 2. By allowing the signal light body to slide away from the support base during the lowering process, it can lie inside the placement slot after being laid down, preventing the signal light body from protruding to the outside. This protects the signal light body, reduces the risk of damage from collisions, and improves safety. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings. Example 1:

[0027] refer to Figure 1 , Figure 2 , Figure 4A safe temporary traffic signal control device includes a support base 1, a support cylinder 2 rotatably connected inside the support base 1, a lifting rod 3 slidably connected through the support cylinder 2, a signal light body 4 bolted to the top of the lifting rod 3, a linear rack 5 bolted to one side of the lifting rod 3, a disc gear 6 rotatably connected to the linear rack 5 inside the support cylinder 2, and a limiting tooth plate 8 slidably connected to the support cylinder 2 on the side of the disc gear 6 away from the linear rack 5, a limiting bolt 7 threadedly connected to the support cylinder 2 on the side of the limiting tooth plate 8 away from the disc gear 6, and a crank handle 9 bolted to the disc gear 6 rotatably connected through the support cylinder 2 on the outside of the support cylinder 2. Rotating the disc gear 6 to engage with the linear rack 5 adjusts the height of the signal light body 4, and twisting the limiting bolt 7 locks the disc gear 6 in place by engaging the protruding teeth on one side of the limiting tooth plate 8 in the tooth grooves of the disc gear 6. It can not only control and adjust the height of traffic signal devices, but also facilitate the locking and unlocking of the adjusted height, thus improving practicality.

[0028] refer to Figure 4 A return spring 17, bolted to the support cylinder 2, is welded to the side of the limiting tooth plate 8 away from the disc gear 6. The return spring 17 is sleeved on the surface of the limiting bolt 7. The rebound force of the return spring 17 can drive the limiting tooth plate 8 to slide away from the disc gear 6, so that the lifting rod 3 can be lowered after the limiting bolt 7 is twisted and reset.

[0029] Brief description of operation: By cranking the handle 9, the disc gear 6 rotates, causing it to mesh with the linear rack 5. This meshes with the rack, driving the lifting rod 3 to slide up and down inside the support cylinder 2, thus adjusting the height of the signal light body 4. Then, by tightening the screw 7, which engages with the threaded connection of the support cylinder 2, the limiting tooth plate 8 slides inside the support cylinder 2, locking onto the surface of the disc gear 6 and limiting the height of the lifting rod 3. Because the limiting tooth plate 8 also has teeth on the side closest to the disc gear 6, even if the teeth of both are pressed together, the teeth on one side of the limiting tooth plate 8 will push the disc gear 6 to rotate via the trapezoidal inclined surfaces on both sides, locking it in the tooth groove of the disc gear 6. Simultaneously, after the limiting bolt 7 is torn back to its original position, the return force of the return spring 17 automatically drives the limiting tooth plate 8 to slide synchronously away from the disc gear 6. Example 2:

[0030] refer to Figure 1 , Figure 2 , Figure 3A safe temporary traffic signal control device includes a sliding seat 10 on the side of a support base 1 away from the limiting bolt 7. The top of the sliding seat 10 has a placement groove 11 for use with the signal light body 4. A conical gear disc 12, rotatably connected to the support base 1, is bolted to one side of the bottom of a support cylinder 2. A conical gear 13, rotatably connected to the support base 1, meshes with the side of the conical gear disc 12 away from the sliding seat 10. A screw 15, threadedly connected to the sliding seat 10, is rotatably connected inside the support base 1. Synchronous pulleys 14 are bolted to the ends of both the screw 15 and the conical gear 13 away from the sliding seat 10. A synchronous belt 16 is sleeved on the surface of the synchronous pulleys 14. During the lowering process of the signal light body 4, the sliding seat 10 slides away from the support base 1, allowing it to lie inside the placement groove 11 after being lowered, preventing the signal light body 4 from protruding outwards. This protects the signal light body 4, reduces the risk of collision damage, and improves safety.

[0031] refer to Figure 1 , Figure 2 Both the support base 1 and the sliding base 10 have casters 18 bolted to their respective sides at the bottom, and a locking device 19 is bolted to one side of each caster 18. This facilitates the movement of the traffic signal device. Simultaneously, the locking device 19 can be used to secure the casters 18, thereby limiting and fixing the traffic signal device.

[0032] refer to Figure 2 A protective pad 20, which works in conjunction with the signal light body 4, is adhered to the bottom of the inner cavity of the placement slot 11. This provides cushioning and protection for the signal light body 4 when it is placed inside the placement slot 11, raising it and preventing damage from impacts.

[0033] refer to Figure 1 , Figure 2 A limiting plate 21 is provided on the top of the sliding seat 10, and fixing bolts 22 threadedly connected to the sliding seat 10 are slidably connected to both sides of the limiting plate 21. By tightening the fixing bolts 22, the limiting plate 21 is bolted and fixed to the top of the sliding seat 10, thereby reinforcing and limiting the signal light body 4 and improving safety.

[0034] refer to Figure 1 A fixing plate 23 is welded to the side of the support base 1 and the sliding base 10 that are close to each other. A connecting bolt 24 is bolted through the inside of the fixing plate 23. By tightening the connecting bolt 24, the two fixing plates 23 are bolted together, so that the support base 1 and the sliding base 10 are fixed together. Thus, the support cylinder 2 can be limited and fixed whether it is upright or laid down.

[0035] Brief description of the usage process: By rotating and folding the support cylinder 2, the signal light body 4 can be laid down. During this rotation, the conical gear disc 12 rotates and meshes with the conical gear 13. Since the conical gear disc 12 is larger than the conical gear 13, the conical gear 13 rotates more times. The conical gear 13 is driven by the synchronous pulley 14 and synchronous belt 16, which in turn drives the screw 15 to rotate synchronously inside the support base 1. Then, the screw 15 engages with the sliding seat 10, causing the sliding seat 10 to slide away from the support base 1. Thus, after being laid down, the signal light body 4 can lie inside the placement slot 11, protecting it with the sliding seat 10. When the signal light body 4 is lifted again, the screw 15 rotates in the opposite direction, allowing the sliding seat 10 to slide back to its original position and approach the support base 1.

[0036] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
