Description

Technical Field

[0001] The invention relates to the technical field of street lamp installation, and in particular to a street lamp cap installation structure with a pitch adjustment function. Background Art

[0002] Street lamps are lighting facilities for nighttime roads, and the installation requirements of street lamps are clearly stipulated. During the installation of the lamp head, if the lamp head deviates at an angle in the horizontal direction, the lighting shape of the entire road surface will also move in the same direction due to the linear propagation property of light. This generally leads to differences in illumination and lighting design between the two lamp poles, which is not ideal. For this reason, when installing the lamp head on the lamp pole, a level is generally used to ensure the horizontal position of the lamp head. Similarly, if the elevation direction of the lamp head deviates at an angle, the entire lighting range of the lamp head will also move forward and backward. For this problem, the angle of the cantilever elevation of the support pole is generally fixed in the design and manufacture of the lamp pole to meet the standard requirement that the elevation angle of the lamp head does not exceed 15°.

[0003] Affected by road conditions, the installation standards for the pitch angles of each lamp head are also different, so the lamp head design needs to have an adjustable function.

[0004] Generally, the angle of the lamp holder is adjusted by setting an axis structure at the connection point between the lamp holder and the lamp pole to meet the adjustment needs. Since the lamp holder is located at the top of the lamp pole and is in an open air environment, the axis structure at the connection is affected by wind and rain erosion and may be damaged due to rust. Therefore, a street lamp holder installation structure with a pitch adjustment function is proposed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a street lamp holder mounting structure with a pitch adjustment function, which has the advantage of isolating the adjustment structure from erosion by rainwater and solves the problems mentioned in the background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a street lamp lamp holder installation structure with a pitch adjustment function, comprising a shell, a lampshade and a lamp holder installed in the shell, the lampshade installed at the bottom of the lamp holder, the lampshade protruding from the bottom of the shell, and a light source installed in the lampshade, a fixing strip is arranged around the edge of the lamp holder, an adjustment component is arranged around the inner wall of the shell, the lamp holder is embedded in the adjustment component through the fixing strip, and the fixing strip can be adjusted at an angle wrapped under the adjustment component, as well as the angle of the lamp holder and the lampshade, and the adjustment of the lighting range of the lamp holder is achieved by adjusting the angle of the lampshade in the lamp holder, and the lampshade angle adjustment structure is located inside the lamp holder, so as to avoid using an axis structure to connect the lamp holder to the lamp post, thereby protecting the adjustment structure and reducing the erosion of the adjustment structure by open air wind and rain.

[0007] Preferably, the adjustment component includes a main body limit frame, a bladder embedded in the limit frame, and a rubber membrane between the limit frame and the bladder. The limit frame is arranged around the inner wall of the shell, and a notch is left in the middle of one of the side walls. The rubber membrane and the bladder are arranged along the path of the limit frame, and the fixing strip is wrapped between the bladder and the rubber membrane. After the angle of the fixing strip changes, the rubber membrane can be tightened to limit and fix the fixing strip after the angle change.

[0008] Preferably, the limit frame is composed of two layers of brackets that are symmetrical up and down, and a gap is left between the two layers of brackets. The upper and lower sides of the rubber membrane are respectively placed on the upper and lower layers of brackets and fixed by rivets. At the same time, the gap is covered to form a hollow channel between the interior of the shell. The remaining hollow channel provides installation space for the laying of cables.

[0009] Preferably, a cable is arranged in the hollow channel, and when the cable is tightened, the rubber membrane can be contracted inward to cooperate with the bladder bag and the fixing strip to lock the fixing strip.

[0010] Preferably, the bag is made of elastic textile material and is filled with granular fillers. When the angle of the fixing bar deviates, the fillers in the bag are pushed in the direction of the deviation and are gradually reset subsequently to fix the deviated fixing bar. At the same time, the granular fillers can absorb rainwater that invades the shell to isolate the rainwater.

[0011] Preferably, the size of the fixing strip is larger than the inner size of the sac and smaller than the outer size of the sac. The fixing strip is sunken in the middle of the sac and can be completely wrapped by the sac. Since the fixing strip is smaller than the outer size of the sac, when the angle of the fixing strip changes, the filler in the sac will first be pushed in the deflection direction and encounter resistance. After the pushing, the filler in the sac will move to the side opposite to the pushing direction to fix the fixing strip after the deflection is completed.

[0012] Preferably, the adjustment component also includes guide wheels and locking caps, and two groups of guide wheels and locking caps are provided respectively, wherein the guide wheels are installed on the inner wall of the shell and are located at the notch of the limit frame path, and the two guide wheels guide the two ends of the cable respectively, and the two ends of the cable are connected with two locking caps after passing through the shell respectively. The cable is guided by the guide wheels and fixed by the locking caps after tightening the cable, so that the bag can be tightened and the deflected fixing strip can be further fixed.

[0013] Preferably, a connecting assembly is provided between the lamp holder and the shell for connection, and the connecting assembly includes a first universal ball and a second universal ball, the first universal ball and the second universal ball are respectively installed on the lamp holder and the shell, a probe rod is installed on the first universal ball, and a sleeve rod is connected to the second universal ball, and the probe rod is slidably connected to the sleeve rod to strengthen the connection between the lamp holder and the shell.

[0014] Preferably, the sleeve rod is hollow inside, the probe rod is inserted into the sleeve rod, and a telescopic spring is installed inside the sleeve rod, with two ends of the telescopic spring fixedly connected to the probe rod and the sleeve rod respectively.

[0015] Preferably, a ball seat for accommodating a universal ball is provided on the lamp holder and the housing, and the ball seat limits the rotation range of the two universal balls through a probe rod and a sleeve rod.

[0016] Compared with the prior art, the present invention provides a street lamp lamp holder mounting structure with a pitch adjustment function, which has the following beneficial effects:

[0017] 1. The adjustment of the lighting range of the lamp holder is achieved by adjusting the angle of the lampshade inside the lamp holder. The adjustment structure of the lampshade angle is located inside the lamp holder, avoiding the use of an axis structure to connect the lamp holder to the lamp post. While protecting the adjustment structure, it also reduces the erosion of the adjustment structure by open air wind and rain.

[0018] 2. The main body bag of the adjusted structure is made of woven materials and filled with particles inside. It is wrapped around the lamp holder and can promptly absorb rainwater that invades the lamp holder to isolate the influence of rainwater on the circuit board and circuit in the lamp holder.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a street lamp head mounting structure with a pitch adjustment function.

[0032] In a typical implementation of a street lamp lamp holder installation structure with a pitch adjustment function of the present application, Figure 1-8 As shown, a street lamp lamp holder installation structure with a pitch adjustment function includes a shell 3, the shell 3 is hollow inside, a heat dissipation cover plate 2 is installed on the top, and a connecting seat 1 is connected to the tail, wherein a lamp holder 5 is arranged inside the shell 3, a lamp shade 4 is connected below the lamp holder 5, the lamp shade 4 protrudes from the bottom of the shell 3, and a light source is installed in the lamp shade 4, a fixing strip 7 is arranged around the edge of the lamp holder 5, an adjustment component 6 is arranged around the inner wall of the shell 3, the lamp holder 5 is embedded in the adjustment component 6 through the fixing strip 7, and the fixing strip 7 can be adjusted in angle in the adjustment component 6, so as to adjust the angle of the lamp holder 5 and the lamp shade 4;

[0033] For details, see Figure 4-Figure 7As shown, the adjustment component 6 includes a limiting frame 61, a bag 63 embedded in the limiting frame 61, and a rubber film 62 between the limiting frame 61 and the bag 63, wherein the limiting frame 61 is arranged around the inner wall of the housing 3, and only a notch is left in the middle of the side wall close to the connecting seat 1, and the rubber film 62 and the bag 63 are arranged along the path of the limiting frame 61 to wrap the fixing strip 7 inside;

[0034] Note, see Figure 6 and Figure 7 As shown, the limit frame 61 is composed of two symmetrical layers of brackets, with a gap left between the two layers of brackets. The upper and lower sides of the rubber membrane 62 are placed on the upper and lower brackets and fixed by rivets, that is, the rubber membrane 62 covers the remaining gap to form a hollow channel between the inner wall of the shell 3, and a cable 64 is arranged in the hollow channel;

[0035] The bag 63 is filled with granular fillers and is made of elastic woven material. The thickness of the bag 63 is thicker than the fixing strip 7, so that the fixing strip 7 can be completely immersed in the bag 63 and wrapped by the bag 63, that is, the size of the fixing strip 7 is larger than the internal size of the bag 63, but smaller than the external size of the bag 63.

[0036] When the fixing strip 7 is sunken in the bag 63, since the bag 63 is filled with granular fillers, the fixing strip 7 can be adjusted in angle when wrapped by the bag 63, but the adjustment of its angle is also affected by the fillers in the bag 63. In a normal state, the fixing strip 7 is in the middle of the bag 63 (at this time, the bottom of the lampshade 4 is in contact with the inner bottom of the shell 3). When the angle of the fixing strip 7 is deflected relative to the adjustment component 6, the fillers in the bag 63 are pushed in the deflection direction synchronously. The pushing process is affected by the resistance of the fillers, and this resistance keeps the fixing strip 7 in a stable state in the adjustment component 6.

[0037] At the same time, when the filler is pushed to one side, the filler moves in the bag 63 to the side opposite to the pushing direction, so that the fixing bar 7 keeps the current state stable after stopping the deflection. However, in this state, the state of the fixing bar 7 may still be deflected due to the influence of external forces on the lampshade 4, such as the influence of wind, which may cause the lighting range of the lampshade 4 to shift.

[0038] After the fixing strip 7 is adjusted to a predetermined angle, both ends of the cable 64 are tightened at the same time, so that the cable 64 is tightened toward the center of the shell 3. However, due to the presence of the rubber film 62, the force of tightening the cable 64 inward acts on the rubber film 62 and acts on the outer wall of the bag 63 through the rubber film 62. That is, at this time, the bag 63 is simultaneously subjected to the forces of the inner fixing strip 7 and the outer rubber film 62. After the lighting range of the lampshade 4 is adjusted to a predetermined angle, the adjustment of the fixing strip 7 is stopped, and both ends of the cable 64 are tightened at the same time, so that the rubber film 62 cooperates with the inner fixing strip 7 to clamp the bag 63. The fillers pushed to the upper and lower sides by the fixing strip 7 cannot flow due to the interaction between the fixing strip 7 and the rubber film 62, so as to fix the fixing strip 7 and make it unable to move, thereby achieving the fixing effect on the fixing strip 7 and the lampshade 4, so that the lampshade 4 after the angle adjustment remains in a stable state.

[0039] In order to achieve the aforementioned fixing effect on the fixing strip 7, refer to Figures 5 to 7 As shown, the adjustment assembly 6 also includes a guide wheel 65 and a locking cap 66. Two groups of guide wheels 65 and locking cap 66 are respectively provided. The two groups of guide wheels 65 are located at the notch on the path of the limit frame 61, and each is supported by a connecting piece. At the same time, the guide wheels 65 and the connecting piece are in a state of rotational connection, and the guide wheels 65 protrude from the formed hollow channel. The locking cap 66 is located on the fitting surface of the shell 3 and the connecting seat 1, and a fixing platform is provided on the fitting surface. After being guided by the guide wheels 65, the two ends of the capsule 63 pass through the fitting surface of the shell 3 and the connecting seat 1, and pass through the fixing platform, and are tightened and fixed by two locking caps 66 respectively;

[0040] Specifically, during installation and use of the lamp holder, the adjustment of the lighting range of the lamp holder is achieved by adjusting the angle of the lampshade 4 inside the shell 3. After opening the heat dissipation cover 2 and adjusting the angle of the internal fixing strip 7, the lighting range of the lampshade 4 is adjusted. A clamp such as a vise is used to clamp both ends of the cable 64 between the fixing platform and the shell 3 at the same time, tighten the cable 64 outward, and then tighten the two locking caps 66 to fix the tightened cable 64, so that the bag 63 is tightened to achieve the fixing effect of the fixing strip 7, and reduce the displacement of the lampshade 4 caused by external forces. Since the positioning structure of the lampshade 4 is inside the shell 3, the adjustment structure can be reduced. The influence of external forces such as wind and rain can be reduced. At the same time, the shaft structure made of metal is not used. Even if some rainwater penetrates into the interior of the shell 3, the adjustment structure will not rust, so as to improve the overall life and service life of the adjustment structure and reduce the maintenance frequency of the structure.

[0041] Further, referring to the lampshade 4 and the connecting assembly 8, in order to improve the connection strength and stability between the lampshade 4 and the housing 3, a connecting assembly 8 is further provided between the lamp holder 5 and the housing 3 for connection, and the connecting assembly 8 includes a first universal ball 81 and a second universal ball 82, and the two universal balls are respectively mounted on the lamp holder 5 and the connecting assembly 8, wherein a probe rod 83 is mounted on the first universal ball 81, and a sleeve rod 85 is mounted on the second universal ball 82, wherein the sleeve rod 85 has a diameter greater than the probe rod 83, and the sleeve rod 85 is hollow inside, and the sleeve rod 85 is sleeved on the probe rod 83, and a telescopic spring 84 is further connected between the probe rod 83 and the sleeve rod 85, and the telescopic spring 84 is located inside the sleeve rod 85, and the ball seats on the lamp holder 5 and the housing 3 for accommodating the universal balls respectively limit the rotation range of the probe rod 83 and the sleeve rod 85;

[0042] When the angle of the fixing strip 7 is adjusted under the wrapping of the bag 63, the angle of the lamp holder 5 also changes. The change in angle can be achieved through the action of the connecting component 8. While ensuring the connection with the shell 3, the angle adjustment range of the lamp holder 5 and the fixing strip 7 is also limited, thereby preventing the fixing strip 7 from escaping from the wrapping range of the bag 63.

[0043] Furthermore, it should be added that the filler in the bag 63 wraps the lampshade 4, the lamp holder 5 and the fixing strip 7. Since the bag 63 is a textile and its internal filler is granular, it has a certain water absorption capacity. When the lamp holder is used in an open-air environment, some rainwater will inevitably penetrate into the shell 3. The bag 63 with water absorption capacity can absorb the penetrated rainwater in time to isolate the rainwater from affecting the circuit board and circuit inside the lamp holder 5.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
