Description

Technical Field

[0001] This utility model relates to the field of fixed bracket technology, and specifically to a fixed bracket for antennas. Background Technology

[0002] An external antenna is an antenna installed outside a device to receive and transmit wireless signals. By adjusting its angle, the signal reception effect can be optimized and the communication quality can be ensured. It is commonly used in television, broadcasting, wireless communication and other fields, and is an important component for improving signal coverage and stability.

[0003] In the existing technology, the bracket structure that supports the external antenna is not easy to adjust, so the antenna cannot be adjusted to a suitable angle to receive signals. In addition, when the antenna is installed on the ground, it usually requires operators to climb up for installation, which is labor-intensive and inconvenient. Therefore, a fixed bracket for antenna is proposed to solve the above problems. Utility Model Content

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-5As shown, a mounting bracket for an antenna includes a support mechanism 1, with an adjustment mechanism 2 at its upper end. The adjustment mechanism 2 includes a lifting cylinder 201, with a lifting lug 202 fixedly mounted on the upper end of its outer wall. A lead screw 207 is rotatably connected to the lower end of one side of the lifting cylinder 201, with its bottom end extending below the lifting cylinder 201 and a knob 208 fixedly connected to its bottom end. A lifting sleeve 209 is threaded onto the outer wall of the lead screw 207, with one side of the outer wall of the lifting sleeve 209 slidingly connected along the outer wall of the lifting cylinder 201. A connecting rod 210 is rotatably connected to the other side of the outer wall of the lifting sleeve 209, with a rotating frame 211 rotatably connected to the end of the connecting rod 210 furthest from the lifting sleeve 209. The rotating frame 211 is generally L-shaped, with its top end rotatably connected to the outer wall of the lifting cylinder 201, and an upper support 212 fixedly embedded in the middle of its lower end. Figure 1 As shown, the lifting cylinder 201 limits the movement direction of the lifting sleeve 209;

[0029] A take-up drum 203 is fixedly installed in the middle of the outer wall of the lifting drum 201. A rotating cover 204 is rotatably connected to the top of the take-up drum 203. A through-hole 205 is opened at one end of the outer wall of the rotating cover 204. A dustproof baffle 206 is fixedly connected to the inner wall of the through-hole 205. Figure 2 As shown, the dustproof baffle 206 is made of rubber, and the center of the dustproof baffle 206 is split to facilitate cable threading;

[0030] A positioning groove 213 is provided in the middle of the top surface of the upper support 212. A spiral disk 214 is rotatably connected to the inner wall of the upper support 212 and located below the positioning groove 213. A knob 216 is fixedly connected to the middle of the bottom surface of the spiral disk 214. The bottom end of the knob 216 extends to the bottom of the upper support 212. Several claw blocks 215 are threadedly connected to the top surface of the spiral disk 214. The outer wall of the claw block 215 is slidably connected to the inner wall of the upper support 212, and one end of each claw block 215 extends into the positioning groove 213. Figure 4 As shown, the surface of the claw block 215 is threaded to mate with the spiral disk 214, so that when the spiral disk 214 rotates around the center, it can push the claw block 215 to extend and retract within the upper support 212.

[0031] The support mechanism 1 includes a vertical pole 101, and lower supports 102 are fixedly installed around the top of the vertical pole 101. Each lower support 102 has a fixing hole 103 at the end away from the vertical pole 101. Figure 1 As shown, a pin can be inserted into the fixing hole 103 to connect to the ground;

[0032] A through hole 104 is provided at one end of the lower part of the outer wall of the upright 101. Clamping wheels 105 are rotatably connected to the upper and lower parts of the inner sidewall of the through hole 104. A winding wheel 106 is rotatably connected to the outer wall of the upright 101 above the through hole 104. A crank 107 is fixedly connected to the winding wheel 106 at the pivot point. The side of the crank 107 extends to the outer side of the upright 101. Figure 5 As shown, the crank 107 has a pre-drilled hole on its side to facilitate the insertion of screws. The screws pass through the crank 107 and are fixed to the side of the upright 101.

[0033] A traction rope 108 is wound and fixed on the outer wall of the winding reel 106. The end of the traction rope 108 passes through the inside of the through hole 104, and the upper end of the through hole 104 extends to the top of the upright 101. A support wheel 109 is rotatably connected to the top of the upright 101. The outer wall of the support wheel 109 is movably connected to the traction rope 108. The top end of the traction rope 108 is fixedly connected to the lifting lug 202. The inner wall of the lifting cylinder 201 is slidably connected along the upper end of the outer wall of the upright 101. Both the clamping wheel 105 and the support wheel 109 support the traction rope 108, thereby preventing the traction rope 108 from wearing.

[0034] The working principle of this utility model:

[0035] When installing the antenna, the crank 107 drives the winding wheel 106 to rotate, thereby adjusting the length of the traction rope 108. When the traction rope 108 is released, the lifting lug 202 is not supported by the traction rope 108, so the lifting cylinder 201 is subjected to gravity and slides down the pole 101. When the traction rope 108 is retracted, the traction rope 108 lifts the lifting lug 202, thereby raising the lifting cylinder 201 along the pole 101. When fixing, screws are driven into the pre-drilled holes on the side of the crank 107, and the screws are fixed to the side of the pole 101.

[0036] When the lifting cylinder 201 falls close to the lower support 102, the screw 207 is rotated by the knob 208. The thread on the surface of the screw 207 pushes the lifting sleeve 209 to move up and down along the side of the lifting cylinder 201, thereby rotating the connecting rod 210 and driving the side rotating frame 211 to rotate around the top rotating shaft, thereby adjusting the angle of the upper support 212.

[0037] When fixing the antenna, first insert the antenna base into the positioning groove 213. Then, rotate the knob 216 to drive the spiral disk 214 to rotate. The top of the spiral disk 214 spirally pushes the claw block 215 to move along the inner wall of the upper support 212. The claw block 215 extends into the positioning groove 213 and abuts against the top of the antenna base, so that the antenna base is fixed inside the positioning groove 213. Then, insert the antenna connecting cable into the through port 205. The cable end extends from the bottom of the cable take-up tube 203 to prevent the cable from being pulled off by the wind.

[0038] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
