Description

Technical Field

[0001] The invention relates to the field of street lamps, in particular to an easily replaceable street lamp. Background Art

[0002] When a street lamp breaks down, maintenance personnel need to work at height, which is not only physically demanding but also dangerous. Therefore, a street lamp that can be easily repaired on the ground is needed.

[0003] In the invention patent with publication number CN105114884A, a solution for controlling the lifting and lowering of street lamps by pulling ropes is proposed. The operating part is mainly composed of a pull rope for controlling the extrusion structure, a pull rope for hanging the lamp head, and a lever structure for side extrusion and fixing the lamp head. The document obviously has the advantage of easy maintenance relative to fixedly installed street lamps. However, after studying the content of the document, it is found that the street lamps need to be hoisted and reset after maintenance, and it does not mention how to achieve accurate repeated positioning between the street lamps, lamp poles and fixed structures. The lever structure of the side fixation only simply describes how to apply pressure to the side of the lamp head, but lacks the specific structure for achieving the extrusion side fixation (how the lever structure is combined with the street lamp housing). Therefore, it is believed that although the document provides a technical concept of pulling ropes to control the lifting and lowering of street lamps for easy maintenance, the technical content provided still has a large number of details missing. It is difficult to produce relevant street lamp products based only on the technical content of the document. Therefore, it is believed that the rope lifting technical solution of the document does not completely solve the problem of inconvenient maintenance of street lamp failures. The technical route of pulling ropes to control the lifting and lowering of street lamps is also adopted.

Figure 4 As shown, a ring 202 is fixedly sleeved on one end of the short tube 201 away from the street lamp 101 in the guide sleeve 200, and an end of the ring 202 away from the short tube 201 is located on the outer side of the guide sleeve 200. The end cap 203 is fastened with threads, and the guide sleeve 200 is matched with the strip groove 201a and the block 208 to form an escape groove 200a. Figure 6 and Figure 7 As shown, a piston 204 is slidably sleeved in the short tube 201, and a spring 205 is arranged between the piston 204 and the end cover 203, one end of the spring 205 passes through the ring 202 and is fixedly connected to the end cover 203, and a pull rope 206 is fixedly connected to the piston 204 along its axial direction, and the pull rope 206 passes through the spring 205 and the end cover 203 and extends to the bottom of the lamp pole 100; Figure 8 As shown, a strip groove 201a is provided on the peripheral wall of the short tube 201 parallel to its axial direction, and a spring piece 207 is sleeved in the strip groove 201a, the middle part of the spring piece 207 is fixedly connected to the short tube 201, and both ends of the spring piece 207 are bent and extended to the inside of the short tube 201, and the bending direction of both ends of the spring piece 207 is oblique to the circular ring 202, and a clamping block 208 is elastically hinged on the outer wall of the circular ring 202 corresponding to the position of the strip groove 201a, and the clamping block 208 is squeezed and clamped with the strip groove 201a.

[0033] Specifically, Figure 3 As shown, the short tube 201 and the top surface of the shell of the street lamp 101 are both arranged horizontally, and the short tube 201 is fixedly connected to the top surface of the shell of the street lamp 101. The guide sleeve 200 is located at the end away from the lamp pole 100 and is in a trumpet shape. The lower half of the trumpet of the guide sleeve 200 is opened and arranged obliquely downward.

[0034] like Figure 6 , Figure 7 As shown, the short tube 201, the spring 205, the ring 202, the end cover 203, and the circular tube sections of the guide sleeve 200 are coaxially arranged, and the strip grooves 201a, the spring pieces, and the blocks 208 are distributed in three groups in a circular array about the ring 202. A pair of retaining springs 209 are clamped on the inner wall of the short tube 201, and the two retaining springs 209 are distributed at both ends of the strip groove 201a. The distances between the two ends of the spring piece 207 and its adjacent retaining springs 209 are both greater than the length of the piston 204. The middle part of the end cover 203 is opened, and the opening edges at both ends of the end cover 203 are provided with rounded corners.

A plug hole 201c is opened

[0036] The working principle and advantages of the device are further explained in combination with the prior art: the existing street lamp 101 pole 100 and the street lamp 101 are fixedly assembled, and as a common lighting facility that is widely used, the street lamp 101 must be beautiful while also taking into account the manufacturing cost control. Therefore, when solving the problem of the inconvenience of high-altitude maintenance of the street lamp 101, the impact of adding related operating components on the design, manufacturing and use of the original street lamp 101 should also be fully considered. Therefore, the present invention does not adopt the technical route on the market similar to the lifting of multi-section lamp poles 100, which is obviously cumbersome to manufacture and maintain and has a high cost. Instead, the pull rope 206 is used to control the suspension and lifting of the street lamp 101. Unlike the document CN105114884A which also adopts the pull rope 206 street lamp 101 lifting scheme, the technical solution of the present invention is more detailed, complete and compact in structure, and the control method is relatively simple.

[0037] The present invention mainly provides a method of unlocking the street lamp 101 and the lamp pole 100, suspending and lifting the street lamp 101, and repeatedly positioning and assembling the street lamp 101 and the lamp pole 100 by operating a single pull rope 206. To achieve the above-mentioned target functions, the present invention also involves the following technical details:

[0038] First, how the street lamp 101 is assembled on the lamp post 100 for use, the street lamp 101 and the lamp post 100 are normally assembled and used. Figure 2 and Figure 5 As shown, the internal structure of the short tube 201 connected between the street lamp 101 and the lamp pole 100 is as follows: Figure 6and Fig. 9 As shown, first, the guide sleeve 200 is fixedly connected with the lamp pole 100, the guide sleeve 200 is fixedly connected with the ring 202, and the short tube 201 is slidably connected with the guide sleeve 200. When one end of the short tube 201 hits the ring 202, the block 208 on the ring 202 will be connected with the strip groove 201a under the action of the spring piece 210. Therefore, under the restriction of the short tube 201 and the ring 202, the position of the short tube 201 and the street lamp 101 connected thereto is fixed relative to the guide sleeve 200 and the lamp pole 100. At the same time, the block 208 will prevent the short tube 201 from rotating through the strip groove 201a adapted to its width, so that the posture of the street lamp 101 is stable, and the street lamp 101 is prevented from swaying due to external factors such as wind.

[0039] Second, how to remove the street lamp 101 from the lamp pole 100? Figure 2 and Figure 6 The position of the pull cord 206 is shown in FIG. 1 . The process of pulling the pull cord 206 once to unlock the street lamp 101 can be referred to as Figure 9~Figure 12 ;

[0040] Fig. 9 The internal state of the short tube 201 when the street lamp 101 is normally assembled and used. Fig. 9 For example, when the pull rope 206 is pulled, the piston 204 moves to the right. The piston 204 follows the bending direction of the two ends of the spring sheet 207, squeezes the two ends of the spring sheet outward in turn, and moves through the spring sheet 207 to reach Fig.10 The position of the piston 204 in;

[0041] by Fig.10 As an example, during the movement of the piston 204, the spring 205 is continuously compressed to store elastic potential energy. At the same time, the piston 204 also squeezes the triangular tip of the end of the block 208 to be located on the bevel side of the short tube 201 (reference Fig.10 The block 208 is pushed toward the outside of the short tube 201 until the piston 204 contacts the retaining spring 209 adjacent to the ring 202. At this time, the right-angled side 208a of the block 208 deflects and leaves the strip groove 201a. A beveled side of the right-angled side 208a adjacent to the block 208 (reference Fig.10 The side marked as B in FIG. 200 enters the strip groove 201 a instead of the right-angle side 208 a;

[0042] by Fig.11Taking the perspective as an example, since the circular ring 202 is fixed relative to the lamp pole 100, when the piston 204 contacts the retaining spring 209, the operator will obviously feel that the pull rope 206 can no longer be pulled. When the pull rope 206 is felt to be "pull in place", the operator can release the pull rope 206. At this time, the spring 205 quickly releases the elastic potential energy to push the short tube 201 away from the circular ring 202, so that the short tube 201 slides toward the outside of the guide sleeve 200. During the process, the block 208 slides to the outer wall of the short tube 201 through the hypotenuse (marked as B), and the spring 205 continues to push the short tube 201. Under the action of inertia, even if the length of the spring 205 is not enough to completely withdraw the short tube 201 from the guide sleeve 200, the purpose of separating the short tube 201 from the guide sleeve 200 can be fully achieved. At this time, the pull rope 206 is connected to the piston 204, and the piston 204 is connected to the short tube 201 and the street lamp 101 through the retaining spring 209, and the release of the pull rope 206 is controlled to lower the street lamp 101 to the ground.

[0043] Third, how to achieve accurate re-positioning of the street lamp 101 and the lamp pole 100 when they are reassembled, such as Fig.12 As shown, when on the ground, the piston 204 is first reset to between the retaining spring 209 and the spring piece 207 inside the short tube 201. The spring piece 207 can be temporarily disassembled or lifted to the outside of the short tube 201 through the socket 201c, so that the piston 204 can be moved back to the zero position. By pulling the pull rope 206, the piston 204 is connected to the short tube 201 and the street lamp 101 through the spring piece 207 to realize upward lifting;

[0044] At this time, the special horn opening of the guide sleeve 200 plays an important guiding role, such as Figure 3 As shown, the bottom of the bell mouth of the guide sleeve 200 is partially retracted toward the lamp pole 100, so that the lower half of the bell mouth of the guide sleeve 200 is in a slanted downward state, which makes it easier for the short tube 201 pulled vertically upward to enter the guide sleeve 200, avoiding the short tube 201 and the bottom edge of the guide sleeve 200 from getting stuck and causing inconvenience in operation, and at the same time, it will not interfere with the short tube 201 restoring a horizontal posture after being pulled back into the guide sleeve 200;

[0045] by Fig.12 For example, when the short tube 201 is reinserted into the guide sleeve 200, the block 208 is pressed against the outer wall of the ring 202 by the action of the spring sheet 210, and one of the straight sides of the right-angled side 208a of the block 208 contacts the outer wall of the ring 202, so that the acute-angled triangle tip at the end of the block 208 is located outside the peripheral wall of the short tube 201. The short tube 201 can slide along the outer wall of the short tube 201 and re-engage in the strip groove 201a by sliding (marked as A) the hypotenuse;

[0046] When the short tube 201 is pulled into a tubular section of the guide sleeve 200 by the pull rope 206, the short tube 201 is in a horizontal posture. At this time, the short tube 201 has not yet been engaged with the block 208. The short tube 201 is allowed to rotate to a certain extent, allowing the street lamp 101 to swing under the action of gravity until the street lamp 101 is vertically downward. Therefore, the posture of the short tube 201 is determined by the street lamp 101, so that the strip groove 201a on the short tube 201 is aligned with the block 208, and then the short tube 201 is pulled again to allow the block 208 to slide smoothly into the strip groove 201a.

[0047] It should be noted that Fig.12 Taking the perspective as an example, the pulling force of the pull rope 206 required for the piston 204 to squeeze through the left end of the spring piece must be greater than the weight of the short tube 201 plus the piston 204 plus the street lamp 101 (in order to achieve the lifting of the short tube 201 and the street lamp 101 through the pull rope 206, the piston 204 and the spring piece), and must also be greater than the pulling force of the pull rope 206 required when the short tube 201 slides and squeezes open the clamping block 208 (in order to pull the piston 204 through the pull rope 206 to drive the short tube 201 to engage with the clamping block 208).

[0048] In summary, the device connects a short tube 201 to the top of the street lamp 101 shell, and the short tube 201 is inserted into the guide sleeve 200 on the lamp pole 100 to realize the connection between the street lamp 101 and the lamp pole 100. The device only pulls the piston 204 through a pull rope 206 to move between the spring piece on the side wall of the short tube 201 and the block 208 on the side wall of the guide sleeve 200, and cooperates with a spring 205 to realize multiple functions such as fixed connection between the street lamp 101, the short tube 201 and the lamp pole 100, and the guide sleeve 200, quick unlocking, hoisting of the street lamp 101, and repeated positioning of the street lamp 101 assembly, etc., and has the advantages of simple structure, low cost, convenient operation and easy maintenance.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
