Description

Technical Field

[0001] This utility model relates to the field of streetlights, and more specifically, to a fall protection device for streetlight fixtures. Background Technology

[0002] As a key infrastructure for road lighting, streetlights have the core function of providing safe and clear nighttime visibility for pedestrians and vehicles. In current road lighting systems, streetlights are usually used as auxiliary components, which are fixedly connected to the light pole by fasteners such as bolts, or installed at the front end of the light pole (or light arm) by plugging in.

[0003] If a light pole is impacted, vibrated, or breaks due to prolonged corrosion or rust, or during severe weather such as storms, lightning, hail, or typhoons, the connection between the light fixture and the pole may loosen, causing the fixture to fall from a height. Since light fixtures typically have weight and fall with considerable speed and impact, they could injure pedestrians or damage vehicles upon impact, potentially leading to serious traffic accidents and posing a significant threat to people's lives and property. Therefore, an improved technology is urgently needed to address this problem in existing technologies and ensure the safety of pedestrians and vehicles on the road. Utility Model Content

[0004] The present invention aims to overcome the defects of the prior art and provide a fall protection device for street lamps.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fall protection device for streetlights, comprising a light pole, a lighting unit, and a fall protection unit. The lighting unit includes a mounting cylinder fixed to the light pole and a light fixture fixedly connected to the mounting cylinder. The fall protection unit includes a mounting ring that is passed through and clamped and fixed to the light pole, and a safety rope connecting the lighting unit and the mounting ring. A snap-fit ​​unit is provided at the mounting ring, comprising a slider, a mounting block, a connecting post connecting the slider and the mounting block, and a fixing ring fixed to the mounting block. The mounting ring has a circular through groove that allows the slider to pass through and an arc-shaped through groove that allows the connecting post to pass through and communicates with the circular through groove. The slider is circular and its diameter is larger than that of the connecting post. The mounting ring has a sliding groove that cooperates with the slider. Both the circular through groove and the arc-shaped through groove communicate with the sliding groove. A connecting block is provided at the mounting cylinder, and a fixing hole is provided at the connecting block. One end of the safety rope passes through the fixing hole and is fixedly connected to the connecting block, and the other end passes through the fixing ring and is fixedly connected to the fixing ring.

[0006] Furthermore, the mounting ring is composed of a first semi-circular ring and a second semi-circular ring. One end of the first semi-circular ring and one end of the second semi-circular ring are fixedly connected by a pin, and the other end of the first semi-circular ring and the other end of the second semi-circular ring are fixedly connected by a fixing bolt.

[0007] The first and second semicircular rings are installed by splicing them together, making installation more convenient.

[0008] Furthermore, both the first and second semicircular rings have the circular through groove, the arc-shaped through groove, and the sliding groove.

[0009] This facilitates the installation of the snap-fit ​​unit.

[0010] Furthermore, a protrusion is fixed at the first semicircular ring, and a groove is provided at the second semicircular ring to mate with the protrusion. The pin passes through the protrusion and the groove. The protrusion has a first through hole through which the pin passes, and the groove has second through holes on both sides for the pin to pass through. Both ends of the pin have hemispherical limiting blocks. The first semicircular ring has a through hole to mate with a fixing bolt, and the second semicircular ring has a threaded hole to mate with a fixing bolt.

[0011] Thus, the first and second semicircular rings are stably connected.

[0012] Furthermore, the lamp post is inserted into the mounting cylinder, and the mounting cylinder is provided with locking bolts that can fix the relative position of the mounting cylinder and the lamp post.

[0013] This makes it easier to install and fix the light fixtures.

[0014] Furthermore, the circular through groove is located at the top of the arc-shaped through groove.

[0015] Furthermore, the diameter of the circular through groove is greater than the width of the arc-shaped through groove.

[0016] Therefore, the arc-shaped through groove can only allow the connecting column to pass through.

[0017] Furthermore, the mounting block is hemispherical, and the diameter of the mounting block is larger than the diameter of the circular through groove.

[0018] Therefore, the circular through slot can only allow the slider to pass through and enter the slot.

[0019] Furthermore, the mounting block has a mounting groove, a fixing post is provided in the mounting groove, and a fixing ring is provided at the fixing post.

[0020] This makes it easier to install the retaining ring.

[0021] Furthermore, safety rope locking blocks are provided at both ends of the safety rope.

[0022] This makes it easier to install and secure the safety rope.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. The fall protection device of this application is equipped with a fall protection unit, thereby reducing the risk of the lamp falling from a height in case of an accident and avoiding safety accidents to people or vehicles below.

[0025] 2. The fall protection device of this application adopts a splicing and snap-fit ​​installation method for the fall protection unit, which makes the installation convenient and quick, and secure.

[0026] 3. The fall protection device of this application can be used as a later-installed component, which can quickly modify existing street lights without affecting the normal use of the lights. Attached Figure Description

[0036] Working Principle: The fall arrestor for streetlights disclosed in this application, during installation, consists of a first and second semi-circular ring connected and fixed by a pin to form a circular mounting ring. This mounting ring is then clamped onto the light pole (or arm) and secured with fixing bolts passing through the first and second semi-circular rings. Next, one end of the safety rope is fixed to the connecting block of the mounting cylinder using a safety rope locking block, and the other end is fixed to the fixing ring of the snap-fit ​​unit using the same safety rope locking block. The mounting cylinder is then installed at the front end of the light pole (or arm) and secured with locking bolts. The slider of the snap-fit ​​unit is then passed through the circular groove at the mounting ring and slid down to the bottom of the groove (due to gravity, the slider will remain at the bottom of the groove and cannot detach from the mounting ring without external force).

[0037] In the event of an accidental fall, the safety rope will hold the light fixture in place, preventing it from falling directly from a height. To disassemble, maintain, or replace the light fixture, first move the slider upwards and remove it from the circular slot, thus disengaging the locking unit from the mounting ring. Then, loosen the locking bolts to remove the light fixture.

[0038] The fall protection device of this application ensures that even if the light fixture is accidentally detached, it will not fall directly from a height and cause danger due to the fall protection unit. Because the fall protection device uses two semi-circular rings, the size of the mounting rings can be adjusted, making it suitable for most light poles or arms on the market, facilitating later retrofitting of the light fixture.

[0039] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention without departing from the scope defined by the claims.
