Description

Technical Field

[0001] The utility model relates to the technical field of signal lamp supporting structures, in particular to a mobile base of a signal lamp. Background Art

[0002] Temporary traffic lights refer to temporary traffic control equipment set up outside the normal traffic light system to deal with specific situations or needs. When facing major events, emergencies, construction and maintenance, etc., when temporary road control is required, the traffic control department will make real-time or short-term adjustments to traffic signals based on actual conditions to adapt to changes in traffic flow, and these temporary traffic lights will be needed.

[0003] Usually, for the sake of portability, these traffic lights are installed on a mobile base to achieve the purpose of going wherever they are needed. For example, the utility model patent with authorization announcement number CN217034931U discloses a foldable anti-dumping temporary traffic light. The prior art includes a mobile base, a traffic light support frame is fixedly installed on the upper end of the mobile base, and signal light pieces are respectively embedded and installed on the left and right sides of the upper end of the signal light support frame, and signal light pieces are also embedded and installed on the front and back of the top of the signal light support frame, and folding support feet are respectively embedded and installed on the three side surfaces of the mobile base, and a photovoltaic component is fixedly installed on the inclined surface of the mobile base.

[0005] 1. The signal light designed in the prior art is manufactured and fixed only by universal wheels to the base and body of the signal light. However, in actual application, the universal wheel is in contact with the ground only by its wheel cross section, and the friction is insufficient. Even if it is fixed by a locking structure, the entire wheel surface may cause the components to move due to external forces or other conditions, causing the signal light and the base to be unstable during use.

[0006] 2. When the road conditions are uncontrolled and the traffic lights are no longer needed, the traffic lights and their bases need to be removed. However, due to the large size of the traffic lights, they cannot be taken away by trucks or other equipment in some cases and can only be removed by other means, such as towing with a hook. In this case, the existing technology cannot solve the above problem.

[0007] In view of this, it is necessary to improve the above defects. Utility Model Content

[0031] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] First embodiment:

[0034] As Figures 1 to 7 shown, the present utility model proposes a moving base for a signal lamp. The moving base includes a signal lamp body 1. The bottom end of the signal lamp body 1 is fixedly connected to a bottom column 2, and the bottom end of the bottom column 2 is fixedly connected to a base 3. In addition to the above components, the moving base designed by the present utility model further includes a substrate 4, a support and moving component 7, and a slide block 14. Among them, protrusions 5 are fixedly connected to both sides and the front and rear parts of the top end of the substrate 4, and a slide rail 6 is fixedly connected to the middle of the front end of the substrate 4. The slide block 14 is arranged within the slide rail 6 and is connected to each other by a buckle structure 16. A moving auxiliary component 15 is arranged on the slide block 14. In a preferred embodiment of the present utility model, the moving auxiliary component 15 is an armrest 18, and the armrest 18 is fixedly connected to the top end of the slide block 14. By using the armrest 18, the device can be manually pushed to move.

[0035] The supporting moving component 7 includes four flipping columns 8, which are respectively arranged beside the bump 5. A threaded groove is formed at the top of the flipping column 8, and a threaded support rod 11 is connected thereto by internal threads. The top of the threaded support rod 11 is fixedly connected to a support foot 12, and a friction portion 17 is arranged at the top of the support foot 12. The friction portion 17 is made of silica gel material or can also be made of other materials with a high coefficient of friction. When it supports on the ground together with the support foot 12, it can increase the friction between the device body and the ground, making the device more stable.

[0036] One side of the flipping column 8 close to the substrate 4 is connected by a bearing to a connecting shaft 9, and the connecting shaft 9 is fixedly connected to the side wall of the substrate 4. The bottom end of the flipping column 8 is fixedly connected to a universal wheel 10. The universal wheel 10 and the support foot 12 are respectively arranged at the bottom end and the top end of the flipping column 8. During use, according to different usage requirements, the universal wheel 10 or the support foot 12 can be flipped downward by flipping the flipping column 8, so as to achieve the purpose of moving or fixing. After the flipping is completed, the device is fixed by a limiting structure 13 arranged between the flipping column 8 and the bump 5.

[0037] To further explain the specific working principle of the present invention, the above-mentioned buckle structure 16 includes a cavity 29 opened at the top end of the slider 14. A sliding rod 30 is fixedly connected to the top end inside the cavity 29. Movable blocks 36 are slidably connected to both sides of the sliding rod 30. A pressing rod 31 and a second pin 32 are respectively fixedly connected to the top end and the bottom end of the movable block 36. The pressing rod 31 and the second pin 32 both pass through the cavity 29 and extend to the outside of the slider 14. Slots 33 for cooperating with the second pin 32 are respectively opened on both sides of the top end inner wall of the slide rail 6. A second spring 34 is fixedly connected to the adjacent ends of the two second pins 32, and a buffer block 35 is fixedly connected to the adjacent ends of the two second springs 34. The buffer block 35 is fixedly connected to the bottom wall of the cavity 29.

[0038] Therefore, when it is necessary to disassemble and assemble the moving auxiliary component 15, the user only needs to pinch the pressing rod 31, which can drive the movable block 36 on the sliding rod 30 to move, so that the second pin 32 starts to displace, squeezes the second spring 34 and moves away from the slot 33 until it completely disengages from the slot 33 and retracts into the cavity 29. At this time, the slider 14 is released from the limit of the slide rail 6. At this time, the user can replace the moving auxiliary component 15.

[0039] In order to further explain the specific working principle of the present utility model, the above-mentioned limiting structure 13 includes a fixing block 20 arranged on the side of the convex block 5 away from the flipping column 8. A through groove 21 is formed in the fixing block 20. A first pin 22 is arranged inside the through groove 21. Through holes 23 and grooves 24 for cooperating with the first pin 22 are respectively formed on the convex block 5 and the flipping column 8. The grooves 24 are arranged in two up and down. One end of the first pin 22 away from the groove 24 is fixedly connected with a pulling part 25. A first spring 26 is sleeved outside the first pin 22. Two ends of the first spring 26 are respectively fixedly connected with a limiting block 27 and a limiting plate 28. The limiting block 27 is located inside the groove 24 and is fixedly connected with the first pin 22. The limiting plate 28 is fixedly connected inside the through hole 23 and is movably connected with the first pin 22.

[0040] Therefore, when it is necessary to flip the flipping column 8, the user only needs to pull the pulling part 25, and the first pin 22 will move accordingly and start to disengage from the groove 24. At this time, the limiting block 27 approaches the limiting plate 28 and compresses the first spring 26. Until the first pin 22 completely disengages from the groove 24, the user can flip the flipping column 8 and align the other groove 24 with the first pin 22. Then release the hand, and the first pin 22 will reset under the deformation of the first spring 26 to complete the fixation again.

[0041] Second Embodiment:

[0042] As shown in the attached Figure 4 figure, in another preferred embodiment of the present utility model, the moving auxiliary component 15 is a trailer hitch 19. The trailer hitch 19 is fixedly connected to the front end of the slider 14. During use, the trailer hitch 19 can be hooked to the rear of the trailer, and then the trailer can be towed.

[0043] It should be noted here that the electrical components mentioned in this article are all electrically connected to an external main controller and 220V mains power supply, or connected to an additional power supply or battery device. And the main controller can be a conventional known device such as a computer for control. The detailed descriptions of known functions and known components are omitted in the specific implementation manners of the present disclosure. To ensure the compatibility of the device, the operation means adopted are consistent with the parameters of market instruments.

[0044] The present utility model and its embodiments have been described above. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the present utility model, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments without creative efforts without departing from the creative purpose of the present utility model, they should all fall within the protection scope of the present utility model.
