Technical Field
[0001] This utility model relates to the field of lawnmower technology, specifically to a lawn mower head that facilitates quick installation of the mowing rope. Background Technology
[0002] A lawnmower is a common gardening tool, mainly divided into handheld and walk-on lawnmowers. The mowing head is the rotating mechanism at the bottom of the mower. Its main principle is to use a motor or engine to drive the mowing head to rotate at high speed. When the mowing head rotates at high speed, the mowing rope also rotates at high speed, thereby cutting weeds. Most existing mowing heads have the mowing rope wound on the outside of the winding reel. The following problems exist with the external winding of the mowing rope: 1. After the mowing rope is wound, the two ends of the mowing rope are limited by the clamps on the base. The height of the mowing rope at both ends cannot be adjusted, making it difficult to adapt to different mowing height requirements. It can only be achieved by manually controlling the height off the ground. 2. The mowing rope lacks stable limiting on the winding reel. The mowing rope on the upper and lower sides interferes when being released, resulting in problems such as no release or release defects. In short, further optimization and improvement are needed. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grass-beating head with a reasonable structural design, a winding reel that enables internal winding and external wire release, and stable wire release.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0005] A grass trimming head for easy and quick installation of grass trimming rope includes a base, a wire feeding reel, a pressure cap, and an end cap arranged sequentially. The end cap and the base are interlocked. The wire feeding reel is sleeved on the base, and grass trimming rope is wound on the wire feeding reel. The wire feeding reel includes a wire feeding post sleeved on the base, and a wire feeding upper plate, a wire feeding partition, and a wire feeding lower plate arranged from top to bottom on the wire feeding post. An upper winding cavity is formed between the inner side of the wire feeding upper plate near the wire feeding post and the wire feeding partition. An upper exit cavity is formed between the outer side of the wire feeding upper plate away from the wire feeding post and the wire feeding partition. At least one upper exit hole is connected between the upper winding cavity and the upper exit cavity. A lower winding cavity is formed between the inner side of the wire feeding lower plate near the wire feeding post and the wire feeding partition. A lower exit cavity is formed between the outer side of the wire feeding lower plate away from the wire feeding post and the wire feeding partition. At least one lower exit hole is connected between the lower winding cavity and the lower exit cavity.
[0006] Preferably, the wire feeding partition is provided with symmetrical limiting grooves, and the limiting groove is provided with a lead wire port on the side corresponding to the wire outlet hole.
[0007] Preferably, the base is symmetrically provided with snap-fit slots, and aluminum clips are detachably fitted to the snap-fit slots. The aluminum clips are provided with waist-shaped holes for the straw rope to pass through.
[0008] Preferably, the inner wall of the upper winding cavity is provided with an upper limit buckle, and the inner wall of the lower winding cavity is provided with a lower limit buckle.
[0009] Preferably, the end cap is fitted onto the outer ring of the pressure cap, and the end cap is symmetrically provided with elastic clips and guide holes.
[0010] Preferably, the base is provided with a guide post adapted to the guide hole and a locking hole for the elastic locking component to engage.
[0011] Preferably, the base is further provided with a fixing post, and a return spring and a washer are sleeved on the fixing post, with the other end of the return spring abutting against the pressure cover.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This practical grass trimmer has grass trimming rope wound in the upper and lower winding cavities of the wire feeding reel. After winding, the rope passes through the upper and lower wire exit holes and engages with the upper and lower wire exit cavities. The grass trimming rope at both ends can exit through the upper or lower wire exit cavity, or one end can exit through the upper wire exit cavity and the other end through the lower wire exit cavity. Since the upper and lower wire exit cavities are at different heights from the ground, the height adjustment function is realized to meet the needs of different grass trimming heights.
[0014] 2. This practical grass trimming head uses a line-laying plate design on the line-laying reel to allow the grass trimming rope to pass through the limiting groove. The inside-out winding of the line not only facilitates the quick installation of the grass trimming rope, but also avoids interference during line laying due to the lack of limiting on the upper and lower sides of the external winding, making line laying more stable and reliable.
