Description

Technical Field

[0001] The present invention relates to the technical field of traffic lights, and more specifically, to a road traffic light based on an expandable structure. Background Art

[0002] Traffic lights are an important part of road traffic. Through clear signal indications, traffic lights enable vehicles and pedestrians to pass through intersections orderly, avoid traffic chaos, reduce the incidence of traffic accidents, and protect the lives and property safety of pedestrians and drivers. And by reasonably allocating traffic time, unnecessary waiting for stops is reduced, and the road traffic capacity is improved. Therefore, traffic lights play an important role in guiding traffic flow and improving traffic safety.

[0003] For existing traffic lights, after installation, they often cannot be adjusted and are not convenient for expansion, which limits the adaptability of the lights under different installation requirements. Especially at intersections with complex road conditions, limited space, or special layouts, traditional installation methods may not meet the requirements. Due to the inconvenience of expanding the signal pole part and the lack of sufficient expansion space reserved, the number of signal lamp heads that can be installed is limited. If expansion is needed later, a new signal pole part may need to be used, which is very inconvenient for subsequent upgrades. If an upgrade is required, an additional pole part needs to be used, the installation is very inconvenient, and it takes longer. Summary of the Invention

[0004] The present invention aims to overcome the defects of the prior art and provides a road traffic light based on an expandable structure.

[0005] To achieve the above object, the present invention provides the following technical solution: A traffic light, comprising a pole part, a signal lamp head, a fixed seat fixedly connected to the pole part, two connecting seats, two first plugging parts, two second plugging parts, and two rectangular frame parts. The frame part has an insertion channel and two strip-shaped through grooves, and the two insertion channels and the two strip-shaped through grooves correspond one by one, and the corresponding insertion channel and strip-shaped through groove are communicated; The first plugging part includes a first plug rod that can be inserted into the insertion channel, a first connecting block connected to the first plug rod and passing through the strip-shaped through groove, and a first positioning plate fixedly connected to the first connecting block. A first locking bolt capable of locking the relative positions of the first plugging part and the frame part is provided at the first positioning plate, and the first plug rod has a limiting channel; The second plugging part includes a slider located in the insertion channel, a second plug rod connected to the slider and capable of being inserted into the limiting channel, a second connecting block connected to the slider and passing through the strip-shaped through groove, and a second positioning plate fixedly connected to the second connecting block. A second locking bolt capable of locking the relative positions of the second plugging part and the frame part is provided at the second positioning plate; The signal lamp head is installed at the frame part.

[0006] Furthermore, the two frame parts are respectively a first frame part and a second frame part. The first frame part is fixedly connected with a first connecting plate, and the first connecting plate is fixedly connected with the fixed seat.

[0007] Furthermore, the frame part includes two horizontal beams and two vertical beams connecting the two horizontal beams. There are strip-shaped grooves on the lower surface of the upper horizontal beam and the upper surface of the lower horizontal beam.

[0008] Thus, the strip-shaped grooves facilitate the installation of the signal lamp head.

[0009] Furthermore, the fixed seat includes a second connecting plate. There are multiple studs at the second connecting plate, and multiple stud through-holes at the first connecting plate. A locking nut is provided on the stud to fixedly connect the first connecting plate and the second connecting plate.

[0010] Thus, it is convenient to fixedly connect the first frame part and the fixed seat.

[0011] Furthermore, the number of the studs is greater than or equal to four.

[0012] Furthermore, two insertion plates are fixedly connected to the first frame part. There are two slots at the second frame part that cooperate with the insertion plates. The second frame part also has a third locking bolt that can lock the relative positions of the insertion plates and the slots.

[0013] Thus, the second frame part and the first frame part can be fixedly installed together in a front-back distribution.

[0014] Furthermore, a vertical sliding rail is fixed to the top end of the first frame part. A lifting sliding plate is installed on the vertical sliding rail. The lifting sliding plate can be inserted into the slot. A fixing bolt is installed on the lifting sliding plate, and there is a threaded hole at the first frame part that can cooperate with the fixing bolt.

[0015] Thus, the first frame part and the second frame part can be fixedly installed in an up-down distribution.

[0016] Furthermore, a first insertion part and a second insertion part are respectively inserted into the two insertion channels of each frame part; the connecting seat is cuboid-shaped. The connecting seat includes a first insertion hole that can allow the first insertion rod to be inserted, a second insertion hole that can allow the second insertion rod to be inserted, and two T-shaped grooves. The connecting seat also has a fourth locking bolt that can lock the relative position of the connecting seat and the first insertion rod and a fifth locking bolt that can lock the relative position of the connecting seat and the second insertion rod.

[0017] Thus, the connecting seat is firmly connected to the first insertion rod and the second insertion rod inserted into the connecting seat.

[0018] Further, the cross-sections of the insertion channel, the first insertion rod, and the first insertion hole are all square and have equal side lengths, and the cross-sections of the limiting channel, the second insertion rod, and the second insertion hole are all circular and have equal diameters.

[0019] Further, the traffic signal can be in a first state, a second state, and a third state. In the first state, the second frame part is located behind the first frame part. The two insertion plates of the first frame part are respectively inserted into the two slots of the second frame part. The two connecting seats are both located on the side of the first frame part and abut against the first frame part. Each connecting seat is inserted by a first insertion rod and a second insertion rod. In the second state, the second frame part is located on the side of the first frame part. The two connecting seats are both located between the two frame parts and abut against both frame parts. The first insertion rod at the first frame part is inserted into an insertion channel of the second frame part, and the first insertion rod at the second frame part is inserted into an insertion channel of the first frame part. The limiting channel of each first insertion rod is inserted by a second insertion rod, and the first insertion hole of each connecting seat is penetrated by a first insertion rod. In the third state, the second frame part is located above the first frame part. The lifting slide plate is inserted into the slot at the lower position of the second frame part. One of the connecting seats is located on the side of the first frame part and is inserted by the first insertion rod of the first frame part and the second insertion rod of the second frame part. One of the two T-shaped grooves of the other connecting seat is inserted by the first positioning plate at the first frame part, and the other is inserted by the second positioning plate at the second frame part.

[0020] Thus, it has multiple installation methods and can select a suitable state for installation according to the needs of on-site installation.

[0021] Further, in the first state, the side surface of each connecting seat, the end of the first insertion rod inserted into the connecting seat, and the end of the second insertion rod are flush.

[0022] Further, in the first state, all the first locking bolts, all the second locking bolts, all the third locking bolts, all the fourth locking bolts, and all the fifth locking bolts are in a locked state.

[0023] Further, in the second state, all the first locking bolts, all the second locking bolts, and all the fourth locking bolts are in a locked state.

[0024] Further, in the third state, all the first locking bolts, all the second locking bolts, the fourth locking bolt and the fifth locking bolt of one of the connecting seats are in a locked state.

[0025] Further, the connecting seat has two groove parts. Two fourth locking bolts are provided at one of the groove parts, and two fifth locking bolts are provided at the other groove part.

[0026] Further, there are four first locking bolts at the first positioning plate, and four second locking bolts at the second positioning plate.

[0027] In actual use, after installation, the unused bolts can be disassembled and not installed.

[0028] Further, the third state is divided into a third installation state and a third expansion state. In the third installation state, the connecting seat installed on the side of the first frame part abuts against both the first frame part and the second frame part, and the side of the connecting seat is flush with the ends of the first insertion rod and the second insertion rod passing through the connecting seat; in the third expansion state, the side of the connecting seat installed on the side of the first frame part is flush with the ends of the first insertion rod and the second insertion rod passing through the connecting seat, and the distance between the connecting seat and the side of the first frame part is greater than or equal to 2 meters.

[0029] Thus, the first insertion rod of the first frame part and the second insertion rod of the second frame part extend out, facilitating the installation of the equipment required for expansion.

[0030] Further, the signal lamp head includes a first signal lamp head unit and a second signal lamp head unit. The first signal lamp head unit includes a first indicator unit and two first mounting plates fixedly connected to the first indicator unit. There are first mounting bolts at the first mounting plates, and the ends of the first mounting bolts can extend into the strip-shaped groove; the second signal lamp head unit includes a second indicator unit, a second mounting plate connected to the second indicator unit, and a mounting bracket connected to the second indicator unit. There are second mounting bolts at both the second mounting plate and the mounting bracket, and the ends of the second mounting bolts can extend into the strip-shaped groove.

[0031] Thus, it is convenient for the installation and fixation of the first signal lamp head unit and the second signal lamp head unit.

[0032] Further, the mounting bracket includes a first horizontal plate, a second horizontal plate, and a connecting vertical plate connecting the first horizontal plate and the second horizontal plate.

[0033] Thus, the installation of the second signal lamp head unit is more firm.

[0034] Further, there are three arrow indicator lights or three circular indicator lights at the first indicator unit.

[0035] Further, there is a rectangular display screen at the second indicator unit.

[0036] In some embodiments, the traffic signal lamp is in the first state, and the first signal lamp head unit is installed on the first frame part.

[0037] Thus, it is suitable for the situation where fewer signal lamp heads need to be installed.

[0038] In some embodiments, the traffic signal lamp is in the second state. Two or more first signal lamp head units are installed on the first frame part, and one or more first signal lamp head units and one or more second signal lamp head units are installed on the second frame part.

[0039] Thus, more first signal lamp head units can be installed, and second signal lamp head units can be installed to indicate relevant text information.

[0040] In some embodiments, the traffic signal lamp is in the third installation state. More than 3 first signal lamp head units are installed on the first frame part, and more than 3 second signal lamp head units are installed on the second frame part.

[0041] Thus, the number of first signal lamp head units on the first frame part and the number of second signal lamp head units on the second frame part can be equal and in one-to-one correspondence. At this time, the second signal lamp head unit can be used to display the countdown.

[0042] In some embodiments, the traffic signal lamp is in the third expansion state. More than 3 first signal lamp head units are installed on the first frame part, and more than 3 second signal lamp head units are installed on the second frame part. A video monitoring unit is installed between the first insertion rod at the first frame part and the second insertion rod at the second frame part.

[0043] Thus, the first insertion rod of the first frame part and the second insertion rod of the second frame part can extend out, so that multiple video monitoring units can be installed.

[0044] Furthermore, the video monitoring unit includes a mounting base and a video acquisition device installed at the mounting base. The mounting base has a first through hole penetrated by the first insertion rod and a second through hole penetrated by the second insertion rod. The mounting base has a first tightening bolt capable of tightly pressing against the first insertion rod and a second tightening bolt capable of tightly pressing against the second insertion rod.

[0045] Thus, it is convenient for the installation and fixation of the video monitoring unit.

[0046] Advantageous effects:

[0047] 1. The traffic signal lamp of the present application has multiple installation methods, and can select a suitable state for installation according to the on-site installation needs, so the installation is very flexible.

[0048] 2. For the traffic signal lamp of the present application, after using the installation method in the first state, if subsequent expansion and upgrade are needed, the upgrade can be carried out on-site without additional rods, so the expansion and upgrade are convenient.
