Description

Technical Field

[0001] The utility model relates to the technical field of street lamps, and in particular to a street lamp aluminum casting shell connection structure. Background Art

[0002] Street lights, as an important part of urban infrastructure, provide lighting for pedestrians and vehicles at night, and also play a role in beautifying the city and enhancing the city's image. Street lights are widely used in urban roads, parks, squares, commercial areas and residential areas. In commercial and residential areas, street lights can also improve the beauty and livability of these places.

[0003] In order to increase safety, workers usually install corresponding accessories on the outer wall of street lamps, such as monitoring equipment or auxiliary lighting fixtures. During the installation process, some monitoring equipment will be directly installed on the outer casing of the street lamp and limited by bolts. Although this method can quickly complete the installation of the monitoring equipment, some monitoring equipment and the bracket structure adopt a fixed structure. If the monitoring equipment is installed in the wrong position, the bolts need to be removed again, and bolt holes will be left on the outer casing of the street lamp, which will cause external impurities to enter the interior of the casing and affect the electrical circuits therein. Utility Model Content

[0004] The utility model aims to provide a street lamp aluminum casting shell connection structure to solve the problem that some monitoring equipment and the bracket structure adopt a fixed structure. If the monitoring equipment is installed in the wrong position, the bolts need to be removed again, and bolt holes will be left in the shell of the street lamp, which will cause external impurities to enter the interior of the shell and affect the electrical circuits therein.

[0005] The utility model provides the following technical solutions: a street lamp aluminum casting shell connection structure, comprising a lamp shell main body and a camera main body, the lower bottom end of the camera main body is fixedly connected to a support rod, an inner cavity is opened inside the lamp shell main body, an inner hole is opened at the upper top of the lamp shell main body corresponding to the position of the support rod, the camera main body is inserted into the inner cavity through the support rod, and a limiting structure for controlling the support rod is arranged inside the inner cavity.

[0006] By adopting the above scheme, the camera body is inserted into the inner cavity through the support rod, and a limit structure for controlling the support rod is provided. No complicated fixing steps are required, and subsequent maintenance and replacement are also convenient. Since the aluminum cast shell of the street lamp has good thermal conductivity, the heat generated inside can be effectively dissipated to the external environment, which helps to keep the operating temperature of the street lamp and the camera within the normal range and extend its service life.

[0007] As a preferred embodiment of the above technical solution, the limiting structure includes a support frame fixedly connected to the inner cavity, the support frame is rotatably connected to a rotating rod, the outer wall of the rotating rod is provided with opposing threads, the outer wall of the rotating rod is symmetrically threaded with a threaded sleeve, a limiting clamping ring is provided at the end of the threaded sleeve, and a clamping ball is fixedly connected to the middle part of the inner wall of the limiting clamping ring.

[0008] By adopting the above solution, by rotating the rotating rod and utilizing the effect of the opposing threads, the two threaded sleeves can be driven to move toward or away from each other on the rotating rod. Since the limit structure adopts the thread adjustment method, the installation and removal process becomes simple and quick. The user can quickly install or remove the camera body by simply rotating the rotating rod, which greatly improves work efficiency.

[0009] As a preferred embodiment of the above technical solution, the limiting structure also includes that the outer wall of the support rod is symmetrically provided with a clamping groove that cooperates with the clamping ball, and the limiting clamping ring is rotatably connected to the inside of the support frame.

[0010] By adopting the above scheme, the card ball in the middle of the inner wall of the limiting clamp cooperates with the card groove on the outer wall of the support rod to achieve precise locking and fixation between the camera body and the lamp housing body. When the camera body needs to be installed or removed, the user only needs to simply rotate the rotating rod to separate or dock the card ball with the card groove.

[0011] As a preferred embodiment of the above technical solution, the end of the threaded sleeve abuts against the inner wall of the limiting clamp ring, and the limiting clamp ring is sleeved on the outer wall of the rotating rod.

[0012] By adopting the above scheme, the end of the threaded sleeve directly abuts against the inner wall of the limiting clamp ring, so that the rotational movement of the rotating rod can be directly transmitted to the limiting clamp ring. This direct transmission method reduces energy loss, improves transmission efficiency, and makes the adjustment process more precise. Since the position of the threaded sleeve on the rotating rod can be precisely adjusted by rotating the rotating rod, it can adapt to camera bodies of different sizes and installation requirements.

[0013] As a preferred embodiment of the above technical solution, the rotating rod extends to the outer side wall of the lamp housing body, a cross groove is provided at the end of the rotating rod, an outer sleeve rack is fixedly connected to the outer side wall of the lamp housing body at a position corresponding to the rotating rod, and a piston is sleeved at the end of the outer sleeve rack.

[0014] With the above solution, the rotating rod extends to the outside of the lamp housing, allowing users to directly touch and operate the rotating rod. The cross slot design at the end allows common tools such as screwdrivers and wrenches to be used for rotation, making it convenient for users to adjust the limit structure to adapt to camera bodies of different sizes or installation requirements. The combined design of the sleeve and the piston can protect the rotating rod from direct impact from the external environment.

[0015] As a preferred embodiment of the above technical solution, a sealing ring having a sealing function is fixedly connected to the upper top of the lamp housing body at a position corresponding to the support rod.

[0016] By adopting the above solution, the sealing ring can effectively prevent external impurities such as moisture and dust from entering the interior of the lamp housing through the gap between the support rod and the lamp housing body, thereby protecting the internal electronic components and the camera body.

[0017] As a preferred embodiment of the above technical solution, the outer side wall of the lamp housing body is fixedly connected with a fixing rod, the end of the fixing rod is fixedly connected with a clamp, and the lower bottom end of the lamp housing body is fixedly connected with a lamp bead body.

[0018] By adopting the above scheme, the design of the fixing rod and the clamp enables the street lamp to be installed more firmly on the ground or other supporting structures. The clamp can fit tightly on the supporting structure to prevent the street lamp from shaking or tilting due to wind or other external forces, thereby ensuring the stability and safety of the street lamp.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] In the utility model, by setting a limiting structure, during use, the camera body can be inserted into the inner hole through the support rod, and then the rotating rod is rotated. The rotating rod can drive the threaded sleeve to move through the opposite thread, and the end of the threaded sleeve will be squeezed to the limiting clamp ring. Since the limiting clamp ring cooperates with the rotation of the support frame, the end of the limiting clamp ring will limit the support rod, and the support rod can be limited again by the clamping ball clamped in the inside of the clamping groove, so as to avoid the support rod and the limiting structure being separated during use.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a street lamp aluminum casting shell connection structure, including a lamp shell main body 1 and a camera main body 2, the lower bottom end of the camera main body 2 is fixedly connected with a support rod 21, an inner cavity 14 is opened inside the lamp shell main body 1, and an inner hole 17 is opened at the upper top of the lamp shell main body 1 corresponding to the position of the support rod 21. The camera main body 2 is inserted into the inner cavity 14 through the support rod 21, and a limiting structure for controlling the support rod 21 is arranged inside the inner cavity 14, which can quickly release the limit on the support rod 21.

[0028] like Figure 2 and Figure 3 As shown, the limiting structure includes a support frame 3 fixedly connected to the inner cavity 14, and a rotating rod 31 is rotatably connected to the inner part of the support frame 3. The outer wall of the rotating rod 31 is provided with opposing threads 32, and the outer wall of the rotating rod 31 is symmetrically threaded with a threaded sleeve 33, and the threaded sleeve 33 can move in relative or opposite directions. A limiting clamping ring 34 is provided at the end of the threaded sleeve 33, and a clamping ball 35 is fixedly connected to the middle part of the inner side wall of the limiting clamping ring 34. The limiting structure also includes a clamping groove 23 symmetrically provided on the outer wall of the support rod 21 that cooperates with the clamping ball 35 so as to limit the support rod 21. The limiting clamping ring 34 is rotatably connected to the inside of the support frame 3, and the end of the threaded sleeve 33 abuts against the inner side wall of the limiting clamping ring 34, and the limiting clamping ring 34 is sleeved on the outer wall of the rotating rod 31.

[0029] like Figure 1 , Figure 2 and Figure 4As shown, the rotating rod 31 extends to the outer wall of the lamp housing main body 1, and a cross groove 311 is opened at the end of the rotating rod 31 so that it can be connected with the cross groove 311 through a tool, thereby driving the rotating rod 31 to rotate, and an outer sleeve frame 15 is fixedly connected to the position of the rotating rod 31 on the outer wall of the lamp housing main body 1, and a piston 16 is sleeved on the end of the outer sleeve frame 15 to protect the rotating rod 31. A sealing ring 22 for sealing is fixedly connected to the position of the support rod 21 at the upper top of the lamp housing main body 1, and a fixing rod 11 is fixedly connected to the outer wall of the lamp housing main body 1. A clamp 12 is fixedly connected to the end of the fixing rod 11, and a lamp bead main body 13 is fixedly connected to the lower bottom of the lamp housing main body 1.

[0030] Working principle: During use, the camera body 2 and the support rod 21 are inserted into the inner hole 17, and then the rotating rod 31 is rotated, and the rotating rod 31 can drive the threaded sleeve 33 to move through the opposite thread 32, and the end of the threaded sleeve 33 will be squeezed to the limiting clamp ring 34. Since the limiting clamp ring 34 cooperates with the rotation of the support frame 3, the end of the limiting clamp ring 34 will limit the support rod 21, and the support rod 21 will be limited again by the clamping ball 35 clamped in the inner part of the clamping groove 23, so as to avoid the support rod 21 and the limiting structure being locked during use. The piston 16 is then inserted into the outer sleeve 15 to prevent external impurities from entering the inner cavity 14 through the outer sleeve 15, which would aggravate the damage to the internal circuit of the camera body 2. In this way, external accessories can be quickly installed, avoiding the situation where the lamp housing body 1 is damaged due to the need to punch holes, affecting its use. After the camera body 2 is installed, the clamp 12 is sleeved on the road pole and the clamp 12 is limited by fixing bolts so that the clamp 12 can always be in contact with the road pole to support the lamp housing body 1.

[0031] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
