Description

Technical Field

[0001] This utility model relates to the field of port machinery lighting technology, specifically a protective lamp cover for port machinery lights. Background Technology

[0002] Harbor lights are lighting fixtures installed on port terminals that are designed to protect against surges and lightning.

[0003] Most existing port machinery lights are bolted to the light frame. In order to prevent the port machinery lights from falling from the height and injuring people, a fall arresting steel cable is connected to the port machinery lights. However, the length of the fall arresting steel cable is fixed and relatively long, which makes the connection inconvenient. Moreover, the light frame is mostly a double-layer structure. The port machinery lights that fall from the upper layer will hang and sway under the pull of the fall arresting steel cable, which can easily collide with nearby port machinery lights, causing multiple sets of port machinery lights to be damaged at the same time, increasing the cost of use.

[0004] Therefore, in order to solve the above problems, a protective lamp cover for port machinery lights is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a protective lamp cover for port machinery lights, in order to solve the problems mentioned in the background art. In the prior art, most port machinery lights are installed on the light frame by bolts. In order to prevent the port machinery lights from falling from the height and injuring people, anti-fall steel wire ropes are connected to the port machinery lights. However, the length of the anti-fall steel wire ropes is fixed and relatively long, which is inconvenient to connect. Moreover, the light frame is mostly a double-layer structure. The port machinery lights that fall from the upper layer will hang and sway under the pull of the anti-fall steel wire rope, which is easy to collide with nearby port machinery lights, causing multiple sets of port machinery lights to be damaged at the same time, increasing the cost of use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective lampshade for port machinery lights, comprising: a lamp post frame, a connecting frame installed on the side wall of the lamp post frame, an mounting frame installed on the outer side of the connecting frame, a bracket fixedly installed on the top surface of the mounting frame by bolts, and a lampshade body installed on the bracket;

[0007] A positioning structure is installed on the lampshade body. The positioning structure includes a first threaded sleeve, which is fixedly installed on one side of the bottom surface of the lampshade body. A first screw is threadedly connected to the inner side of the first threaded sleeve, and a steel wire rope is fixedly connected to the bottom end of the first screw. A second threaded sleeve is fixedly installed on the other side of the bottom surface of the lampshade body. A second screw is threadedly connected to the inner side of the second threaded sleeve. A through groove is opened on the side wall of the second screw. A rotating sleeve is integrally formed on the bottom surface of the second screw, and a clamping screw is threadedly connected to the bottom surface of the second screw.

[0008] Preferably, the bracket is installed on the top surface of the mounting frame near the connecting frame.

[0009] Preferably, the wire rope has a spiral structure and is wrapped around the outside of the connecting frame, mounting frame and support in the middle.

[0010] Preferably, the end of the wire rope is inserted into the through groove and passes through the second screw via the through groove.

[0011] Preferably, the rotating sleeve is located on the outside of the clamping screw, and the upper end of the clamping screw is located on the inside of the through groove and abuts against the surface of the wire rope.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The steel wire rope provided by this utility model can be connected to one side of the bottom surface of the lampshade body through the first screw and the first threaded sleeve, and one end of the steel wire rope is fixed to the second screw through the tightening screw, which is convenient to operate. At the same time, the second screw is fixed to the other side of the bottom surface of the lampshade body through the second threaded sleeve, which allows the steel wire rope to wrap around the outside of the connecting frame and the mounting frame. When the lampshade body falls off, the steel wire rope can still fix the lampshade body in the original position of the mounting frame, avoiding the lampshade body from shifting and shaking, which would aggravate the damage.

[0013] This utility model features a positioning structure that bolts the bracket to the top surface of the mounting frame. By screwing the first screw upwards into the first threaded sleeve, the wire rope is fixedly connected to the bottom surface of the lampshade body. Rotating the rotating sleeve screws the upper end of the second screw into the second threaded sleeve, allowing the middle portion of the wire rope to pass through the connecting frame and mounting frame from below, forming a "U" shape. The wire rope then passes between the bracket and the lampshade body, and the end of the wire rope passes through a through groove. Finally, the tightening screw is rotated; the upper end of the tightening screw can move within the through groove. The positioning structure can be easily assembled by fitting and abutting against the bracket, thus fixing the bracket inside the through groove. The length of the steel wire rope inserted into the through groove can be adjusted according to the actual situation, making it suitable for installation needs in various positions. The positioning structure and the lampshade body can form a ring, allowing the lampshade body to be stably located at the connection between the connecting frame and the mounting frame. When the bracket falls off the mounting frame, the lampshade body can be fixed at the connection between the connecting frame and the mounting frame and shake, preventing horizontal displacement on the mounting frame and collision with nearby lampshade bodies, thus reducing damage.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 The present invention provides an embodiment of a protective lamp cover for port machinery lights:

[0021] The lamp post bracket 1, connecting bracket 11, mounting bracket 12, support bracket 13 and lampshade body 14 used in this application are products that can be purchased directly on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0022] A protective lamp cover for a port machinery light includes: a lamp post frame 1, a connecting frame 11 installed on the side wall of the lamp post frame 1, a mounting frame 12 installed on the outer side of the connecting frame 11, a bracket 13 fixedly installed on the top surface of the mounting frame 12 by bolts, and a lamp cover body 14 installed on the bracket 13.

[0023] A positioning structure 2 is installed on the lampshade body 14. The positioning structure 2 includes a first threaded sleeve 21, which is fixedly installed on one side of the bottom surface of the lampshade body 14. A first screw 22 is threadedly connected to the inner side of the first threaded sleeve 21. A steel wire rope 23 is fixedly connected to the bottom end of the first screw 22. A second threaded sleeve 24 is fixedly installed on the other side of the bottom surface of the lampshade body 14. A second screw 25 is threadedly connected to the inner side of the second threaded sleeve 24. A through groove 26 is opened on the side wall of the second screw 25. A rotating sleeve 27 is integrally formed on the bottom surface of the second screw 25. The bottom surface of the second screw 25 is threadedly connected to... The lampshade body 14 has a tightening screw 28 and a steel wire rope 23. It can be connected to one side of the bottom surface of the lampshade body 14 through the first screw 22 and the first threaded sleeve 21. One end of the steel wire rope 23 is fixed to the second screw 25 through the tightening screw 28, which is convenient to operate. At the same time, the second screw 25 is fixed to the other side of the bottom surface of the lampshade body 14 through the second threaded sleeve 24, which allows the steel wire rope 23 to be wrapped around the outside of the connecting frame 11 and the mounting frame 12. When the lampshade body 14 is detached, the steel wire rope 23 can still fix the lampshade body 14 in the original position of the mounting frame 12, avoiding displacement and shaking of the lampshade body 14 and aggravating the damage.

[0024] Furthermore, the bracket 13 is installed on the top surface of the mounting frame 12 near the connecting frame 11. The connecting frame 11 and the mounting frame 12 are arranged crosswise. When the wire rope 23 is wrapped around the outside of the connecting frame 11 and the mounting frame 12, it can limit the position of the bracket 13 on the mounting frame 12.

[0025] Furthermore, the wire rope 23 has a spiral structure and is wrapped around the outside of the connecting frame 11, the mounting frame 12 and the bracket 13 in the middle. The wire rope 23 can limit the bracket 13 and prevent the bracket 13 from shifting on the mounting frame 12.

[0026] Furthermore, the end of the wire rope 23 is inserted into the through groove 26 and passes through the second screw 25 through the through groove 26. The wire rope 23, together with the second screw 25, can connect both ends of the wire rope 23 to the bottom surface of the lampshade body 14, so that the wire rope 23 and the bottom surface of the lampshade body 14 form a closed ring, ensuring the installation stability of the positioning structure 2.

[0027] Furthermore, the rotating sleeve 27 is installed on the outside of the clamping screw 28. The upper end of the clamping screw 28 is located inside the through groove 26 and abuts against the surface of the wire rope 23. The rotating sleeve 27 can protect the clamping screw 28 from the outside. The clamping screw 28 can press the wire rope 23 against the inner wall of the through groove 26, so that the wire rope 23 is kept fixed inside the second screw 25, preventing loosening and reducing the stability of the positioning structure 2.

[0028] Working principle: During installation, the bracket 13 is fixed to the top surface of the mounting bracket 12 with bolts. The first screw 22 is screwed upward into the first threaded sleeve 21, thus fixing the wire rope 23 to the bottom surface of the lampshade body 14. The rotating sleeve 27 is rotated to screw the upper end of the second screw 25 into the second threaded sleeve 24. The middle part of the wire rope 23 passes through the connecting bracket 11 and the mounting bracket 12 from the bottom, making the wire rope 23 have a "U" shape. It passes between the bracket 13 and the lampshade body 14. Then, the end of the wire rope 23 passes through the through groove 26. Then, the tightening screw 28 is rotated. The upper end of the tightening screw 28 can move inside the through groove 26. The positioning structure 2 can be easily assembled by fitting and abutting against the bracket 13, thus fixing the bracket 13 inside the through groove 26. The length of the steel wire rope 23 passing through the through groove 26 can be adjusted according to the actual situation, which can be used to meet the installation needs of various positions. The positioning structure 2 and the lampshade body 14 can form a ring, so that the lampshade body 14 can be stably located at the connection between the connecting frame 11 and the mounting frame 12. When the bracket 13 falls off the mounting frame 12, the lampshade body 14 can be fixed at the connection between the connecting frame 11 and the mounting frame 12 and shake, so as to avoid horizontal displacement on the mounting frame 12 and collision with the nearby lampshade body 14, thereby reducing damage.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
