Description

Technical Field

[0001] This utility model relates to the technical field of support rods, and in particular to a multifunctional retractable positioning extension rod. Background Technology

[0002] Support devices are widely used in people's production and daily life. In particular, telescopic pole support devices are used in fishing rods, landing net poles, cable supports and equipment supports due to their advantages such as adjustable length and easy grip.

[0003] Existing extension rods, such as the reinforced locking buckle and telescopic support rod disclosed in utility model patent application number 202123429756.2, mainly include a locking adjustment handle. The front end of the locking adjustment handle has a screw hole. The screw passes through the screw hole at the front end of the locking adjustment handle and the screw hole in the locking sleeve connecting part in sequence and is connected to the nut. The outer side of the locking sleeve connecting part near the front end of the locking handle has an annular slide rail around the locking screw. The annular slide rail is not set at the same height. In use, when it is necessary to unfold the rod, both locking sleeves of the reinforced locking buckle are locked to reinforce the rod section connection. When the rod is retracted, the locking bolt in the upper locking sleeve is opened, and the upper rod section can be retracted into the lower rod section to complete the retraction of the rod.

[0004] However, most existing support rods still require external tools to rotate the screws during assembly and use, which is very troublesome. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-functional retractable positioning extension rod that facilitates the assembly and adjustment of the extension rod length by setting an internal hexagonal knob, eliminating the need for external tools and improving the flexibility of the device.

[0006] This utility model discloses a multifunctional retractable positioning extension rod, including a connecting mechanism; it also includes a fixing mechanism, a limiting mechanism, and an adjusting mechanism. The fixing mechanism is installed on the connecting mechanism to facilitate fixing the connecting mechanism. The limiting mechanism is installed on the connecting mechanism to facilitate limiting the adjusting mechanism. The adjusting mechanism is installed on the limiting mechanism to adjust the tightness of the limiting mechanism. When it is necessary to adjust the length of the support rod, the operator rotates the adjusting mechanism, which causes the limiting mechanism to loosen its clamping on the connecting mechanism, facilitating the adjustment of the length of the connecting mechanism. Then, the adjusting mechanism is tightened again to fix the connecting mechanism in place by the limiting mechanism.

[0007] Preferably, the connecting mechanism includes a sleeve, an extension tube, and a connecting sleeve. The sleeve has an internal cavity, the extension tube is slidably installed in the cavity of the sleeve, and the connecting sleeve is fitted at the connection between the sleeve and the extension tube. By setting the connecting sleeve, the relative position of the sleeve and the extension tube is adjusted, and the sleeve is pulled out of the cavity of the extension tube by the length of the extension rod.

[0008] Preferably, the fixing mechanism includes two sets of first ear plates, screws, and a first nut. Both sets of first ear plates are mounted on the connecting sleeve. Both sets of first ear plates have through holes, and one set of first ear plates has a hexagonal hole. The screw is rotatably installed in the through holes of both sets of first ear plates, and the first nut is installed in the hexagonal hole of the first ear plate. The screw is placed in the hexagonal hole of the first ear plate, and then the operator rotates the screw so that the screw passes through the through hole and is screwed into the first nut. The screw pulls the two sets of first ear plates closer together, so that the bottom end of the connecting sleeve is fixed to the sleeve.

[0009] Preferably, the limiting mechanism includes two sets of second ear plates and an annular slide. Both sets of second ear plates are mounted on the connecting sleeve, and both sets of second ear plates have through holes. The annular slide is installed at one of the through holes. By setting two sets of second ear plates, it is convenient to adjust the tightness of the top of the connecting sleeve. By setting an annular slide, it is convenient to adjust the distance between the two sets of second ear plates by the adjusting mechanism.

[0010] Preferably, the adjustment mechanism includes a hexagonal bolt, an internal hexagonal knob, a handle, a boss, and a second nut. The hexagonal bolt is installed in the through holes of two sets of second ear plates. The internal hexagonal knob is installed on the hexagonal bolt. The handle is rotatably installed in the through hole of the hexagonal bolt and has a hexagonal hole. The boss is installed on the handle and engages with the annular slide rail. The second nut is installed in the hexagonal hole of the handle. The operator places the internal hexagonal knob on the hexagonal bolt so that the screw head of the hexagonal bolt engages with the internal hexagonal knob, and then passes the hexagonal bolt through the two sets of through holes of the second ear plates. Install the second nut into the hexagonal hole of the handle, and install the handle and the boss onto the hexagonal bolt. Then, turn the internal hexagonal knob, which drives the hexagonal bolt to rotate. The hexagonal bolt and the second nut are screwed together, making the boss fit with the handle and bringing the two sets of second ear plates closer together. The two sets of second ear plates moving closer together cause the top of the connecting sleeve to fix the extension tube. When it is necessary to adjust the length of the extension tube, turn the handle. The handle rotates outward along the annular slide, and the handle drives the second nut to rotate off the hexagonal bolt, causing the two sets of second ear plates to gradually move away from each other, making it easier to adjust the length of the extension tube.

[0011] Preferably, the housing of the hexagonal knob also has grooves; by setting the grooves, it is convenient for staff to manually rotate the hexagonal knob, making it convenient for staff to install and adjust.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: when it is necessary to adjust the length of the support rod, the operator rotates the adjustment mechanism, which causes the limiting mechanism to loosen its clamping on the connecting mechanism, making it easier to adjust the length of the connecting mechanism. Then, the adjustment mechanism is tightened again to fix the connecting mechanism in place by the limiting mechanism. Attached Figure Description

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0020] like Figures 1 to 5As shown, the multifunctional retractable positioning extension rod of this utility model includes a connecting mechanism 01; it also includes a fixing mechanism 02, a limiting mechanism 03, and an adjusting mechanism 04. The fixing mechanism 02 is installed on the connecting mechanism 01 to facilitate fixing the connecting mechanism 01. The limiting mechanism 03 is installed on the connecting mechanism 01 to facilitate limiting the adjusting mechanism 04. The adjusting mechanism 04 is installed on the limiting mechanism 03 to adjust the tightness of the limiting mechanism 03. The connecting mechanism 01 includes a sleeve 11, an extension tube 12, and a connecting sleeve 13. The sleeve 11 has a cavity inside. The extension tube 12 is slidably installed in the cavity of the sleeve 11. The connecting sleeve 13 is fitted at the connection between the sleeve 11 and the extension tube 12. The fixing mechanism 02 includes two sets of first ear plates 21, screws 22, and first nuts 23. Both sets of first ear plates 21 are installed on the connecting sleeve 13. Both sets of first ear plates 21 have through holes, and one set of first ear plates 22 has a through hole. The ear plate 21 has hexagonal holes and screws 22 are rotatably installed in the through holes of the two sets of first ear plates 21. The first nut 23 is installed in the hexagonal hole of the first ear plate 21. The limiting mechanism 03 includes two sets of second ear plates 31 and an annular slide 32. Both sets of second ear plates 31 are installed on the connecting sleeve 13. Both sets of second ear plates 31 have through holes. The annular slide 32 is installed at one of the through holes. The adjusting mechanism 04 includes a hexagonal bolt 41, an internal hexagonal knob 42, a handle 43, a boss 44, and a second nut 45. The hexagonal bolt 41 is installed in the through holes of the two sets of second ear plates 31. The internal hexagonal knob 42 is installed on the hexagonal bolt 41. The handle 43 is rotatably installed in the through hole of the hexagonal bolt 41. The handle 43 has a hexagonal hole. The boss 44 is installed on the handle 43 and fits into the annular slide 32. The second nut 45 is installed in the hexagonal hole of the handle 43. The internal hexagonal knob 42 also has a textured outer shell.

[0021] During operation, firstly, screw 22 is placed in the hexagonal hole of the first ear plate 21. Then, the operator rotates screw 22 so that it passes through the through hole and is screwed into the first nut 23. Screw 22 pulls the two sets of first ear plates 21 closer together, fixing the bottom end of the connecting sleeve 13 to the sleeve 11. The operator then places the internal hexagonal knob 42 onto the hexagonal bolt 41 so that the screw head of the hexagonal bolt 41 engages with the internal hexagonal knob 42. Next, the hexagonal bolt 41 is passed through the two sets of through holes of the second ear plate 31. The second nut 45 is installed in the hexagonal hole of the handle 43. The handle 43 and the boss 44 are then installed on the hexagonal bolt 41. Finally, the internal hexagonal knob 42 is rotated. The knob 42 drives the hex bolt 41 to rotate. The hex bolt 41 and the second nut 45 are screwed together to make the boss 44 fit with the handle 43, so that the two sets of second ear plates 31 are close together. The two sets of second ear plates 31 are close together, which drives the top of the connecting sleeve 13 to fix the extension tube 12. When it is necessary to adjust the length of the extension tube 12, the handle 43 is turned. The handle 43 rotates outward along the annular slide 32. The handle 43 drives the second nut 45 to rotate off the hex bolt 41, so that the two sets of second ear plates 31 are gradually moved away. The sleeve 11 is pulled out of the cavity of the extension tube 12 to extend the length of the extension rod. By setting the vent, it is convenient for the staff to manually rotate the internal hex knob 42, which is convenient for the staff to install and adjust.
