Description

Technical Field

[0001] The utility model relates to the technical field of mops, and more specifically to a high-strength mop rod. Background Art

[0002] In daily household cleaning, a mop is often used. To facilitate the use of the mop, the mop rod generally has a function of adjusting the length.

[0003] After adjusting the length of the existing mop rod, the adjusted length of the mop rod is generally fixed by spirally tightening the plastic ring. However, during long-term use, the continuous tightening and recovery of the plastic ring easily causes the plastic ring to become fatigued, resulting in the plastic ring being easily broken, which affects the adjustment and fixation of the mop length. In view of this, we propose a high-strength mop rod. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet practical needs, and provide a high-strength mop rod to solve the technical problem that the plastic ring is easily broken when the existing mop rod is fixed by spirally tightening the plastic ring after adjusting the length.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a high-strength mop rod, comprising an outer sleeve, a threaded sleeve is passed through the top of the outer sleeve, the open end of the threaded sleeve extends to the bottom of the outer sleeve, the open end of the threaded sleeve is threadedly connected to a screw, the bottom of the screw is fixedly connected to an inner sleeve, the inner wall of the inner sleeve is slidably connected to the threaded sleeve, and the outer wall of the inner sleeve is limitedly slidable with the inner wall of the outer sleeve.

[0006] Preferably, a through hole is opened at the top of the outer sleeve, the closed end of the threaded sleeve is passed through the through hole and extends to the outside of the outer sleeve, and a handle is rotatably connected to the outer wall of the outer sleeve.

[0007] Preferably, a limiting ring is fixedly sleeved on the closed end surface of the threaded sleeve, a limiting groove adapted to the limiting ring is opened along the position of the limiting ring in the through hole, and the threaded sleeve is limited in rotation by the limiting ring and the limiting groove.

[0008] Preferably, the handle is frame-shaped, and a connecting rod is fixedly connected to the bottom of the handle. A clamping cavity is provided on the outer wall of the outer sleeve relative to one end of the connecting rod. One end of the connecting rod extends into the clamping cavity and is rotatably connected to the inner walls on both sides of the clamping cavity through a rotating shaft.

[0009] Preferably, the inner wall of the top of the handle is provided with a plurality of arc-shaped notches which are concave toward the top of the handle.

[0010] Preferably, inner walls on both sides of the outer sleeve are provided with sliding grooves connecting the two ends of the outer sleeve, and the outer wall of the inner sleeve is provided with sliding blocks adapted to the sliding grooves at positions relative to the sliding grooves.

[0011] Preferably, a hand wheel is fixedly connected to the top end of the threaded sleeve.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the utility model adjusts the length of the mop rod, the outer sleeve is fixed by the handle surface, and the threaded sleeve is rotated by the hand wheel. The threaded sleeve rotates in the through hole and drives the limit ring to rotate in the limit groove. The threaded sleeve and the screw are spirally tightened or separated, driving the slider on the outer wall of the inner sleeve and the slide groove on the outer wall of the outer sleeve to slide in a limited manner. The inner sleeve and the outer sleeve are separated or aggregated to change the length of the mop rod without additional fixation. At the same time, the design of the inner sleeve can reduce the entry of water into the threaded sleeve and the screw, and reduce the rust of the threaded sleeve and the screw when encountering water, thereby improving the strength and service life of the mop rod.

[0014] 2. The utility model designs the handle so that when the mop is in use, the user holds the tail end of the mop with one hand and grasps the handle with the other hand, thereby reducing the moment of pressing the mop. Compared with the traditional method of directly pressing the middle part of the mop with the other hand, the user can reduce bending reading and bending fatigue; the inner wall of the top of the handle is provided with a plurality of arc-shaped notches that are concave toward the top of the handle, which is more convenient for fitting with the user's fingers, so that the user can hold the handle more firmly, and prevent the mop from falling out of the user's hand due to water in the user's hand when mopping the floor.

[0021] like Figures 1 to 4 As shown, the utility model relates to a high-strength mop rod, comprising an outer sleeve 1, a threaded sleeve 2 is passed through the top of the outer sleeve 1, the open end of the threaded sleeve 2 extends to the bottom of the outer sleeve 1, the open end of the threaded sleeve 2 is threadedly connected with a screw 3, the bottom of the screw 3 is fixedly connected with an inner sleeve 4, the inner wall of the inner sleeve 4 is slidably connected to the threaded sleeve 2, the outer wall of the inner sleeve 4 is limitedly slid with the inner wall of the outer sleeve 1, and the top of the threaded sleeve 2 is fixedly connected with a hand wheel 6. When the length of the mop rod needs to be adjusted, one hand holds the surface of the outer sleeve 1, and the threaded sleeve 2 is rotated by the hand wheel 6. The threaded sleeve 2 and the screw 3 are spirally tightened or separated, driving the outer wall of the threaded sleeve 2 to slide with the inner wall of the inner sleeve 4, and the outer wall of the inner sleeve 4 to slide with the outer wall of the outer sleeve 1, so that the inner sleeve 4 is separated or aggregated with the outer sleeve 1, thereby changing the length of the mop rod.

[0022] Specifically, a through hole 101 is opened at the top of the outer sleeve 1, and the closed end of the threaded sleeve 2 is passed through the through hole 101 and extends to the outside of the outer sleeve 1. When the threaded sleeve 2 is rotated by the hand wheel 6, the threaded sleeve 2 is driven to rotate in the through hole 101, and the outer wall of the outer sleeve 1 is rotatably connected to a handle 5, which is used to hold the outer sleeve 1.

[0023] Furthermore, a limiting ring 201 is fixedly sleeved on the closed end surface of the threaded sleeve 2, and a limiting groove 102 adapted to the limiting ring 201 is opened along the position of the limiting ring 201 in the through hole 101. The threaded sleeve 2 is limited in rotation by the limiting ring 201 and the limiting groove 102. The rotation of the threaded sleeve 2 in the through hole 101 drives the limiting ring 201 to rotate in the limiting groove 102, thereby preventing the threaded sleeve 2 from falling off from the outer sleeve 1.

[0024] Furthermore, the handle 5 is in the shape of a frame, and a connecting rod 501 is fixedly connected to the bottom of the handle 5. A clamping cavity 103 is provided on the outer wall of the outer sleeve 1 relative to one end of the connecting rod 201. One end of the connecting rod 501 extends into the clamping cavity 103 and is rotatably connected to the inner walls of both sides of the clamping cavity 103 through a rotating shaft. When the mop is used up, the handle 5 is rotated around the connection between the clamping cavity 103 and the connecting rod 501, so that the handle 5 is in a vertical state, and the hook of the frame-shaped handle 5 can be used.

[0025] Furthermore, the inner wall at the top of the handle 5 is provided with a plurality of arc-shaped notches 502 which are recessed toward the top of the handle 5 , so as to fit more conveniently with the user's fingers, and the user can hold the handle 5 more firmly.

[0026] It is worth mentioning that the inner walls on both sides of the outer sleeve 1 are provided with sliding grooves 104 connecting the two ends of the outer sleeve 1, and the outer wall of the inner sleeve 4 is provided with a slider 401 adapted to the sliding groove 104 at a position relative to the sliding groove 104. The threaded sleeve 2 and the screw rod 3 are spirally tightened or separated, driving the slider 401 on the outer wall of the inner sleeve 4 and the sliding groove 104 on the outer wall of the outer sleeve 1 to slide in a limited manner.

[0027] Working principle: This embodiment provides a high-strength mop rod. When in use, one hand holds the surface of the grip 5 so that the user's fingers fit into the arc-shaped notch 502 to fix the outer sleeve 1. The other hand rotates the threaded sleeve 2 through the hand wheel 6. The threaded sleeve 2 rotates in the through hole 101 and drives the limiting ring 201 to rotate in the limiting groove 102. The threaded sleeve 2 and the screw rod 3 are spirally tightened or separated, driving the outer wall of the threaded sleeve 2 and the inner wall of the inner sleeve 4 to slide, and at the same time driving the slider 401 on the outer wall of the inner sleeve 4 and the slide groove 104 on the outer wall of the outer sleeve 1 to limit and slide. The inner sleeve 4 is separated or aggregated from the outer sleeve 1 to change the length of the mop rod. When the mop is finished using, the grip 5 is rotated around the clamping cavity 103 and the connecting rod 501 as the center, so that the grip 5 is in a vertical state, and the frame-shaped grip 5 is hooked.
