Description
Technical Field
[0001] The utility model relates to the technical field of pool leaf fishing nets, in particular to a length adjusting mechanism and a pool leaf fishing net. Background Art
[0002] During the long-term use of a pool, various sundries will exist in it. For example, lighter sundries such as leaves will float on the pool surface, and heavier sundries will sink to the bottom of the pool. In order to ensure the cleanliness of the pool water and the safety of swimming, it is necessary to clean the sundries in the pool.
[0003] However, in the existing technology, when the existing staff use a fishing net to fish the sundries in the pool, they often need to replace the fishing tools to fish the sundries floating on the water surface and the sundries sinking to the bottom of the pool respectively. The work efficiency is low, and the length of the fixed rod of the fishing net is fixed and cannot fish the fallen leaves in the middle of the pool. Therefore, the staff need to use an extended fishing net rod to fish the fallen leaves in the pool.
[0004] Therefore, we need a length adjusting mechanism and a pool leaf fishing net to solve the problem of adjusting the length of the grip rod of the existing pool leaf fishing net, and can also realize the adjustment of the length of the grip rod of the pool leaf fishing net. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a length adjusting mechanism and a pool leaf fishing net to solve the problem of adjusting the length of the grip rod of the existing pool leaf fishing net as mentioned in the above background art, and can also realize the adjustment of the length of the grip rod of the pool leaf fishing net.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A length adjusting mechanism includes a grip rod. The surface of the adjusting rod is movably connected to the inside of the grip rod. The end of the adjusting rod is fixedly connected to the surface of the mounting block. An installation groove is opened on the surface of the mounting block. The surface of the installation insert block is inserted into the installation groove. The surface of the installation insert block is fixedly connected to the side surface of the leaf fishing net frame body.
[0007] Preferably, a slot is opened on the top surface of the mounting block. The bottom end of the fixed shaft is fixedly connected to the top surface of the slot. The surface of the through hole of the rotary buckle is rotatably connected to the surface of the fixed shaft. The bottom surface of the rotary buckle abuts against the top surface of the installation insert block. The slot communicates with the installation groove.
[0008] Preferably, the installation groove is arranged in a "convex" shape and does not completely penetrate the top surface of the mounting block.
[0009] Preferably, a notch is opened on the surface of the adjusting rod. The surface of the insertion piece is clamped to the surface of the notch. The surface of the insertion piece is movably connected to the inside of the movable cavity. The movable cavity is arranged inside the grip rod. A return spring is arranged on the surface of the movable cavity.
[0010] Preferably, the top surface of the movable cavity abuts against the inner surface of the sleeve, the inner circumferential surface of the sleeve is movably connected to the outer surface of the grip rod, the end surface of the sleeve abuts against the end of the compression spring, the other end of the compression spring abuts against the surface of the blocking ring, the inner circumferential surface of the blocking ring is fixedly connected to the outer circumferential surface of the grip rod, and the outer circumferential surface of the grip rod is fixedly connected to the inner circumferential surface of the limiting ring.
[0011] Preferably, the notch is arranged in a "ring shape", the number of notches is several, and several notches are arranged at equal intervals on the outer surface of the adjusting rod.
[0012] A pool leaf net includes a length adjustment mechanism.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: by clamping the end of the insertion piece on the surface of the notch, and then movably connecting the surface of the insertion piece to the surface of the movable cavity, the adjusting rod can be prevented from shrinking inside the grip rod, so that the adjusting rod can be locked inside the grip rod. By arranging a return spring on the surface of the insertion piece, the insertion piece can be automatically lifted upward in the movable cavity by the elastic force of the return spring. Therefore, when the insertion piece is separated from the notch and the adjusting rod is pulled outward, its length can be adjusted. By abutting the inner surface of the sleeve against the top surface of the insertion piece, when the length of the adjusting rod needs to be locked inside the grip rod, the inner wall of the sleeve compresses the top end of the insertion piece, so as to limit the insertion piece from clamping on the surface of the notch. When the length of the adjusting rod needs to be adjusted, the limiting ring is compressed by stretching the sleeve, so that the insertion piece moves upward by the elastic force of the return spring; further solving the problem of adjusting the length of the grip rod of the existing pool leaf net, and the length of the grip rod of the pool leaf net can also be adjusted.

When it is necessary to adjust the length of the adjusting rod 2, by stretching the sleeve 4, the limiting ring 15 is compressed, so that the insertion piece 14 moves upwards due to the elastic force of the return spring 17.
[0033] Embodiment V
[0034] A swimming pool leaf fishing net includes a length adjusting mechanism.
[0035] In actual use, by movably connecting the surface of the adjusting rod 2 to the inside of the grip rod 1, its length can be contracted inside the grip rod 1. By fixedly connecting the end of the adjusting rod 2 to the surface of the mounting block 7, then an installation groove 8 is opened on the top surface of the mounting block 7, the surface of the mounting plug 9 is inserted into the inside of the installation groove 8, and the end of the mounting plug 9 is fixedly connected to the surface of the leaf fishing net frame body 6, so that the adjusting rod 2 and the leaf fishing net frame body 6 are linked and installed.
