Description

Technical Field

[0001] The utility model relates to the technical field of feeder cards, in particular to a feeder card with a self-tightening function. Background Art

[0002] In the field of communications, feeder is an important medium for signal transmission. Its stable connection and fixation are crucial to the quality and stability of signal transmission. However, the existing feeder card technology has some shortcomings in practical applications.

[0003] On the one hand, during long-term use, the feeder is prone to loosening or even falling off, which will not only cause signal transmission interruption or instability, affecting communication quality, but may also require frequent maintenance and adjustments, increasing operation and maintenance costs and workload.

[0004] On the other hand, existing feeder cards have poor adaptability to feeders of different sizes. With the continuous development of communication technology, the specifications and models of feeders are becoming increasingly diversified, but the designs of many feeder cards are relatively fixed and cannot be flexibly adjusted according to the size of the feeder. To solve the above problems, we propose a feeder card with a self-tightening function. Utility Model Content

Example

[0021] See also Figures 1-6 The utility model provides a technical solution: a feeder card with a self-tightening function, comprising a threaded rod 1; a sliding block 2, the inner side of the sliding block 2 is slidably connected to the outer side of the threaded rod 1; a fixing device 3, the outer side of the fixing device 3 is fixedly connected to the outer side of the sliding block 2, and the fixing device 3 is used to fix the feeder; a nut 4, the inner side of the nut 4 is threadedly connected to the outer side of the threaded rod 1; a bracket 5, the outer side of the bracket 5 is fixedly connected to the end of the threaded rod 1 away from the nut 4; a locking bolt 6, the outer side of the locking bolt 6 is threadedly connected to the inner side of the bracket 5; the fixing device 3 includes a fixing ring 31, the outer side of the fixing ring 31 is threadedly connected to the sliding block 2 The outer side of the fixing ring 31 is fixedly connected, the inner side of the fixing ring 31 is threadedly connected to the clamping device 32, and the side of the fixing ring 31 away from the sliding block 2 is fixedly connected to the self-locking device 33. The fixing device 3 is provided with two groups, which are respectively arranged on both sides of the threaded rod 1. When in use, the bracket 5 is fixed to the position where the feeder card is required by the locking bolt 6 to provide support for the entire feeder card. The feeder is passed through the fixing ring 31 and the clamping device 32 on the fixing device 3. By rotating the nut 4, the sliding block 2 is slid on the threaded rod 1 to adjust the position of the fixing device 3. At the same time, the self-locking device 33 can further enhance the stability of the fixation and prevent the feeder from loosening.

[0022] The clamping device 32 includes a threaded column 321, the outer side of the threaded column 321 is threadedly connected to the inner side of the fixing ring 31, the end of the threaded column 321 away from the fixing ring 31 is fixedly connected to a knob 322, and the inner side of the threaded column 321 is slidably connected to a clamping assembly 323. When in use, the position of the clamping assembly 323 is adjusted by adjusting the position of the threaded column 321, so that the clamping assembly 323 can adapt to feeders of different specifications.

[0023] The clamping assembly 323 includes a sliding rod 231, the outer side of the sliding rod 231 is slidably connected to the inner side of the threaded column 321, the end of the sliding rod 231 away from the threaded column 321 is fixedly connected to the arc plate 233, the end of the sliding rod 231 away from the arc plate 233 is provided with a rebound spring 232, the end of the rebound spring 232 away from the sliding rod 231 is fixedly connected to the inner side of the threaded column 321, the outer side of the arc plate 233 is fixedly connected to a protective pad 234, and the outer side of the protective pad 234 is fixedly connected to an anti-slip strip 235. When in use, the knob 322 is rotated to drive the threaded column 321 to rotate in the fixing ring 31, and the rotation of the threaded column 321 causes the clamping assembly 32 3 moves in the direction of the feeder. When the curved plate 233 contacts the feeder, the sliding rod 231 slides in the threaded column 321, compressing the rebound spring 232. The elastic force of the rebound spring 232 causes the curved plate 233 to apply a certain pressure to the feeder to achieve clamping of the feeder. The protective pad 234 and the anti-slip strip 235 can increase the friction with the feeder, improve the stability of the clamping, and protect the feeder surface from damage. At the same time, by setting the rebound spring 232, when the feeder is worn or the fixing device 3 is loose, resulting in a larger distance between the feeder and the fixing ring 31, the rebound spring 232 can drive the curved plate 233 to move toward the feeder, continue to press the feeder, and prevent the feeder from sliding.

[0024] The self-locking device 33 includes a fixing plate 331, the bottom of which is fixedly connected to the outer side of the fixing ring 31, a fixing hole 332 is opened in the wall of the fixing plate 331, and a locking assembly 333 is fixedly connected to the outer side of the fixing plate 331. The fixing holes 332 and the locking assemblies 333 in the self-locking devices 33 on both sides correspond to each other. When in use, the locking assembly 333 in the self-locking device 33 is inserted into the fixing hole 332, and the locking assembly 333 fixes the fixing plate 331, thereby fixing the fixing ring 31 to prevent the fixing ring 31 from moving.

[0025] When the cam 331 is in the unlock state, the locking lever 3333 is locked and the locking lever 3333 is locked, so the cam 331 can be unlocked and the locking lever 3333 can be unlocked.

[0026] Working principle:

[0027] During use, the bracket 5 is fixed to the position where the feeder card is required by the locking bolt 6, providing support for the entire feeder card. The feeder is passed through the fixing ring 31 and the clamping device 32 on the fixing device 3. By rotating the nut 4, the sliding block 2 slides on the threaded rod 1, and the position of the fixing device 3 is adjusted so that the two fixing devices 3 are close to each other. The nut 4 limits the position of the fixing device 3.

[0028] At the same time, the fixing devices 3 move closer to each other, driving the two self-locking devices 33 to move closer to each other. The locking assembly 333 on the fixing plate 331 is inserted into the fixing hole 332. The locking rod 3333 rotates around the rotating rod 3332, allowing the fixing block 3331 to pass through the fixing hole 332 on the fixing plate 331. After the fixing block 3331 passes through the fixing hole 332, the locking rod 3333 naturally droops under the influence of its own gravity.

[0029] After the fixing device 3 is fixed, the knob 322 is rotated to drive the threaded column 321 to rotate in the fixing ring 31. The rotation of the threaded column 321 causes the clamping assembly 323 to move toward the feeder. When the curved plate 233 contacts the feeder, the sliding rod 231 slides in the threaded column 321, compressing the rebound spring 232. The elastic force of the rebound spring 232 causes the curved plate 233 to apply a certain pressure to the feeder, thereby clamping the feeder. The protective pad 234 and the anti-slip strip 235 can increase the friction with the feeder and improve the stability of the clamping.

[0030] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
