Description

Technical Field

[0001] This utility model relates to the field of fence technology, and in particular to a fence structure with protective properties. Background Technology

[0002] The background technology of protective fencing is mainly related to its application in the fields of safety, protection, and isolation. With the increasing safety requirements in industries such as industry, construction, transportation, and military, protective fencing has been widely used as an effective safety protection facility.

[0003] Existing similar devices lack flexibility in height adjustment. In different usage scenarios, such as protecting objects or areas of different heights, fixed-height guardrails are difficult to meet the needs. At the same time, traditional devices may lack a mechanism for conveniently adjusting the angle of the rotating plate. In different protection scenarios, such as for protection areas of different shapes or layouts, the fixed-angle rotating plate cannot adapt well, resulting in poor protection. Furthermore, the transmission relationship between the various components of the device is not flexible enough, making it difficult to adjust the transmission position according to actual needs, which affects the overall functionality of the device.

[0013] Through the above technical solution, the first straight slant gear meshes with the second straight slant gear and the first straight slant gear meshes with the third straight slant gear.

[0033] The back of the guardrail 1 is provided with a transmission mechanism 3. The transmission mechanism 3 includes a connecting frame 301 fixedly connected to the left side of the connecting block 207. The connecting frame 301 is rotatably connected to a transmission shaft 302. The transmission shaft 302 is fixedly connected to a turntable 303. The back of the turntable 303 is rotatably connected to a handle 304. The transmission shaft 302 is fixedly connected to a first straight helical gear 305.

[0034] The top of the fixed block 102 is fixedly connected to the limit rod 306, the inside of the connecting frame 301 is rotatably connected to the second straight helical gear 307, the top of the second straight helical gear 307 is fixedly connected to the first transmission block 308, and the inside of the connecting frame 301 is rotatably connected to the third straight helical gear 309.

[0035] The first straight helical gear 305 meshes with the second straight helical gear 307, and the first straight helical gear 305 meshes with the third straight helical gear 309. There are two first transmission blocks 308, and the two first transmission blocks 308 are respectively fixedly connected to the top of the second straight helical gear 307 and the bottom of the third straight helical gear 309.

[0036] An adjustment mechanism 4 is provided on the back of the guardrail 1. The adjustment mechanism 4 includes a worm gear 401 rotatably connected inside the mounting block 201. A rotating shaft 402 is rotatably connected inside the lifting guardrail 104. A rotating plate 403 is fixedly connected to the outside of the rotating shaft 402. A worm wheel 404 is fixedly connected to the outside of the rotating shaft 402. A threaded rod 405 is sleeved on the outside of the limiting rod 306. A second transmission block 406 is fixedly connected to the bottom of the worm gear 401.

[0037] The top of the threaded rod 405 is fixedly connected to a second transmission block 406. The threaded rod 405 is threadedly connected inside the fixed block 102. The worm 401 and the worm wheel 404 mesh with each other. There are two second transmission blocks 406. The two second transmission blocks 406 are fixedly connected to the bottom of the worm 401 and the top of the threaded rod 405 respectively. The threaded rod 405 is threadedly connected inside the mounting post 103.

[0038] The implementation principle of a protective fence structure in this application embodiment is as follows: During installation, the ground plug 101 at the bottom of the guardrail 1 is first inserted into the ground. After the guardrail 1 is fixed, the push plate 206 can be pressed according to the scene requiring protection. The push plate 206 drives the sliding rod 204 to slide inside the sliding block 202, thereby driving the locking block 203 to move forward. At this time, the locking block 203 moves inside the sliding groove inside the mounting block 201. After the front end of the locking block 203 contacts the mounting block 201, the sliding block 202 can be moved downward. After the sliding block 202 moves downward, the positions of the first transmission block 308 and the second transmission block 406 are aligned and connected. Then, the handle 304 can be held and the turntable 303 can be rotated clockwise to make the turntable... 303 drives the transmission shaft 302 to rotate, causing the first straight helical gear 305, which is fixedly connected to the outside of the transmission shaft 302, to rotate clockwise. Since the first straight helical gear 305 meshes with the third straight helical gear 309, when the first straight helical gear 305 rotates clockwise, the third straight helical gear 309 rotates counterclockwise, thereby driving the first transmission block 308, which is fixedly connected to the bottom of the third straight helical gear 309, to rotate counterclockwise. And through the second transmission block 406, which is fixedly connected to the top of the threaded rod 405, the threaded rod 405 is driven to rotate counterclockwise. At this time, the threaded rod 405 drives the mounting block 201 to move upward, thereby driving the lifting guardrail 104 to move upward. When it is necessary to lower, simply rotate the turntable 303 counterclockwise.

[0039] After adjusting the height of the lifting guardrail 104, the sliding block 202 can be moved upward by pressing the actuating plate 206. This causes the second straight helical gear 307, which is fixedly connected to the top of the second straight helical gear 307, to insert into the second transmission block 406, which is fixedly connected to the bottom of the worm 401. At this time, the actuating plate 206 can be released to fix the sliding block 202, thereby fixing the position of the first transmission block 308. The turntable 303 can then be rotated. The turntable 303 rotates clockwise, and through the first transmission block 308 and the second transmission block 406, it drives the worm 401 to rotate clockwise. Since the worm 401 meshes with the worm wheel 404, when the worm 401 rotates clockwise, the worm wheel 404 rotates counterclockwise, thereby driving the rotating plate 403 to rotate counterclockwise. When the rotating plate 403 needs to rotate clockwise, simply rotate the turntable 303 counterclockwise to complete the adjustment of the angle of the rotating plate 403.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
