[0057] In daily life, when people clean the kitchen, bathroom or high walls and windows, since some areas to be cleaned are relatively high, they need a cleaning tool that can be used for cleaning without climbing or standing on the ground, such as a retractable wiper. Existing wipers are prone to swinging left and right or even up and down during operation, causing the user to slip in the direction of force input, and even easily causing the user to bump and get injured. This embodiment provides a retractable wiper, which effectively solves the technical problem that existing wipers are prone to swinging during operation.

[0058] See also Figure 1-Figure 14 The embodiment of the present application provides a telescopic wiper, including a wiper rod 2, an adjusting rod 3, a connecting sleeve 4 and a locking ring 5; a wiper head 1 is provided at the first end of the wiper rod 2; an elastic clip 21 is provided at the second end of the wiper rod 2; a plurality of adjusting holes 31 matching the elastic clip 21 are provided on the side wall of the adjusting rod 3; the locking ring 5 is annular, and the locking ring 5 is provided with a first notch 51 connected to its own center hole; the locking ring 5 is movably sleeved on the outer periphery of the wiper rod 2; the second end of the wiper rod 2 extends into the interior of the adjusting rod 3, so that the elastic clip 21 is snap-locked with any adjusting hole 31; the connecting sleeve 4 is covered and sleeved on the first end of the adjusting rod 3, and the locking ring 5 is located in the connecting sleeve 4; the rotating connecting sleeve 4 is threadedly connected to the first end of the adjusting rod 3, so that the locking ring 5 contacts and abuts against the end surface of the adjusting rod 3.

[0059] More specifically, the elastic clip 21 is a V-shaped spring piece with a marble installed inside the wiper rod 2, and the surface of the elastic clip 21 is provided with a through hole for the marble to extend out, and the marble matches the adjustment hole 31; multiple adjustment holes 31 are arranged at equal intervals along the length direction of the adjustment rod 3; the inner wall of the connecting sleeve 4 is provided with a first internal thread, and the first end of the adjusting rod 3 is provided with a first external thread matching the first internal thread; when installed, the inner wall of the locking ring 5 is surrounded and fitted on the outer wall of the wiper rod 2, and the outer wall of the locking ring 5 is tightly fitted with the inner wall of the connecting sleeve 4; the locking ring 5 is made of non-rigid material, such as nylon and other materials with certain extrusion deformation properties.

[0060] The beneficial effects of this embodiment are as follows: (1) the wiper rod 2 and the adjustment rod 3 can be connected by installing the elastic clip 21 in different adjustment holes 31, so as to achieve the effect of adjusting the total length of the wiper rod 2 and the adjustment rod 3, meet the demand for adjustable length of the telescopic wiper, and can be applied to various scenes with different requirements for telescopic wiper length; and the elastic clip 21 and the adjustment hole 31 can be used to prevent the adjustment rod 3 and the wiper rod 2 from rotating relative to each other during the use of the telescopic wiper, which is conducive to ensuring that the telescopic wiper can be used normally; (2) the connection between the wiper rod 2 and the adjustment rod 3 of the telescopic wiper is also provided with a connecting sleeve The sleeve 4 is threadedly connected to the adjusting rod 3, thereby further strengthening the connection between the wiper rod 2 and the adjusting rod 3. At the same time, a locking ring 5 is provided in the connecting sleeve 4 and is sleeved on the outer periphery of the wiper rod 2. The locking ring 5 is designed with a first notch 51 so that the connecting sleeve 4, the locking ring 5 and the wiper rod 2 can fit tightly together during installation, thereby eliminating the gap between the wiper rod 2 and the adjusting rod 3 and the tolerance gap of the spring piece, which is beneficial to ensuring the stability of the wiper rod 2 and the adjusting rod 3 in the horizontal and vertical directions, and avoiding the situation where the telescopic wiper 2 swings left and right and up and down when in use, effectively solving the technical problem that the existing wiper is easy to swing during operation.

[0061] Further, in this embodiment, please refer to Figure 5 and Figure 6 The connecting sleeve 4 includes a collar portion 41 and a retaining ring portion 42 formed by extending inward from the end edge of the collar portion 41; the collar portion 41 is threadedly connected to the first end of the adjusting rod 3; and the locking ring 5 contacts and abuts between the retaining ring portion 42 and the end surface of the adjusting rod 3. The retaining ring portion 42 can be provided to form a crimping effect on the locking ring 5, and the first notch 51 of the locking ring 5 is designed so that the locking ring 5 can be adaptively opened or compressed, so that the locking ring 5 is sealed and installed between the retaining ring portion 42 and the end surface of the adjusting rod 3, effectively eliminating the gap between the wiper rod 2 and the adjusting rod 3 and the tolerance gap of the spring sheet.

[0062] More specifically, the inner wall of the retaining ring part 42 is provided with a bevel, and the inner diameter of the retaining ring part 42 gradually decreases in the direction away from the adjusting rod 3, and the locking ring 5 is provided with a matching inclined outer wall. The retaining ring part 42 and the locking ring 5 cooperate through the bevel, which can further make the connecting sleeve 4, the locking ring 5, and the wiper rod 2 fit tightly and not loose; the outer periphery of the ring part 41 is provided with anti-slip grooves 91, which can increase the friction with the human body, so that the user can better hold the connecting sleeve 4 for rotation, which is beneficial to increase the efficiency of installing the connecting sleeve 4, increase convenience, and give the user a good use experience.

[0063] Further, in this embodiment, please refer to 4 and Figure 8 The second end of the wiper rod 2 is provided with a connecting clamp 6; the connecting clamp 6 is provided with an elastic part; the connecting clamp 6 contacts and abuts against the inner wall of the adjustment rod 3 through the elastic part. The setting of the connecting clamp 6 does not affect the movement of the wiper rod 2 in the adjustment rod 3, so that the wiper rod 2 and the adjustment rod 3 are tightly fitted, and the gap between the wiper rod 2 and the adjustment rod 3 can also be effectively eliminated. In combination with the snap fit of the elastic clamp 21 and the adjustment hole 31, and the tight covering of the connection part by the connecting sleeve 4 and the locking ring 5, the wiper rod 2 and the adjustment rod 3 are locked in three ways, so that the force and output force of the telescopic wiper are more stable, and the phenomenon of the telescopic wiper swinging left and right and up and down when in use is avoided, so as to achieve the effect of stable connection, so that the user can use force as he likes, achieve a better use state, and ensure the user's use experience.

[0064] More specifically, the connecting clamp 6 is detachably connected to the wiper rod 2, and the connecting clamp 6 is stuck inside the second end of the wiper rod 2. The outer peripheral wall of the connecting clamp 6 is provided with at least two connecting rings 62, and the inner peripheral wall of the wiper rod 2 is provided with a connecting groove matching the connecting ring 62. Through the snap fit between the connecting ring 62 and the connecting groove, the connecting clamp 6 is tightly fitted to the wiper rod 2, and the two connecting rings 62 are separated by a distance, which can eliminate the influence of burrs on assembly.

[0065] Furthermore, in the present embodiment, the elastic part includes a plurality of arc-shaped spring pieces 61 arranged around the center thereof, and there is a gap between two adjacent arc-shaped spring pieces 61. By utilizing the adaptive deformation of the arc-shaped spring pieces 61, the arc-shaped spring pieces 61 can contact and abut against the inner wall of the wiper rod 2 without affecting the movement of the wiper rod 2 in the adjustment rod 3, and the connection stability between the wiper rod 2 and the adjustment rod 3 can be further increased. In particular, by uniformly fitting the peripheral wall of the adjustment rod 3 with the plurality of arc-shaped spring pieces 61 arranged around the center, the center line of the connecting clamp 6 coincides with the center line of the adjustment rod 3, and in combination with the use of the connecting sleeve 4 and the locking ring 5, the center line of the connecting clamp, the center line of the connecting sleeve, the center line of the adjustment rod and the center line of the wiper rod can all coincide, so that the center line of the entire telescopic wiper is located on the same straight line, which is conducive to ensuring the stability of the telescopic wiper when in use.

[0066] Further, in this embodiment, please refer to Figure 11-Figure 14 The wiper head 1 is connected to the first end of the wiper rod 2 through the connecting rod 13; there is an angle between the connecting rod 13 and the wiper rod 2. The angle between the connecting rod 13 and the wiper rod 2 is designed so that the connection between the connecting rod 13 and the wiper rod 2 forms an angle. This arrangement makes the wiper head 1 tilt outward compared to the vertical wiper rod 2, so that the wiper head 1 can better fit the wall surface. This design is in line with ergonomics and makes the user feel more comfortable holding the telescopic wiper.

[0067] More specifically, the angle between the connecting rod 13 and the wiper rod 2 can be an acute angle, a right angle or an obtuse angle, preferably an obtuse angle such as 150°, which makes it more convenient for the user to wipe the wall with the telescopic wiper.

[0068] Further, in this embodiment, please refer to Figure 11-Figure 14 The wiper head 1 comprises a scraper 11 and a mounting sleeve 12; the mounting sleeve 12 is in a tubular shape with both ends open, and a second notch 121 communicating with the central hole of the mounting sleeve 12 is provided on the side wall of the mounting sleeve 12; the scraper 11 is inserted into the mounting sleeve 12, and the wiper rubber strip 111 of the scraper 11 extends out of the second notch 121. The plug-in sleeve design of the mounting sleeve 12 and the scraper 11 can not only ensure the connection stability between the scraper 11 and the mounting sleeve 12, so that the user can use it normally, but also has the advantage of convenient disassembly and assembly. After the wiper rubber strip 111 has been used for a corresponding life time, the scraper 11 can be quickly disassembled and removed from the mounting sleeve 12 so as to install a new scraper 11 and the wiper rubber strip 111, which is conducive to extending the service life of the entire telescopic wiper.

[0069] More specifically, it is preferred that the mounting sleeve 12 is vertically connected to the connecting rod 13, and the connecting rod 13 is located on the symmetry axis of the mounting sleeve 12. This can effectively ensure the left-right balance of the entire telescopic wiper, so that the user can better grasp the center of gravity of the telescopic wiper and make it easier for the user to wave the telescopic wiper for cleaning.

[0070] Further, in this embodiment, please refer to Figure 11-Figure 14 , and further includes a hanging member 7; the hanging member 7 is provided with an arc-shaped hook 71; and the cross section of the mounting sleeve 12 is in a circular ring shape with a second notch 121. Since the wiper rubber strip 111 of the existing common wiper is directly hung on the wall and stored touching the wall, the service life of the wiper rubber strip 111 will be affected over time. However, through the arc design of the arc hook 71 and the outer wall of the mounting sleeve 12, the large arc of the arc hook 71 and the small arc of the mounting sleeve 12 can be appropriately distanced, so that the wiper rubber strip 111 does not touch the wall or the scraper member 11 when stored, which is conducive to increasing its service life.

[0071] More specifically, the suspension member 7 includes a mounting base and at least two arc-shaped hooks 71. The mounting base is provided with a mounting hole connected to the outside. The first end of each arc-shaped hook 71 is connected to the bottom of the mounting base, and the second end of each arc-shaped hook 71 is bent and extended into a hook-shaped structure. The two arc-shaped hooks 71 are arranged in parallel, and the distance between the two arc-shaped hooks 71 is slightly larger than the outer diameter of the connecting rod 13, so that the entire telescopic wiper can be hung on the suspension member 7.

[0072] Furthermore, in this embodiment, there are one or more adjusting rods 3; when there are multiple adjusting rods 3, two adjacent adjusting rods 3 are detachably connected in series. The elastic clamp 21 and multiple adjusting holes 31 can be used to adjust the length of the telescopic wiper in a small range, and the series connection of multiple adjusting rods 3 can be used to adjust the length of the telescopic wiper in a large range. The combination of the two can maximize the length adjustment range of the telescopic wiper, effectively improve the use range of the telescopic wiper, and meet different length requirements in different use scenarios.

[0073] More specifically, a handle sleeve 92 is provided at the end of an adjustment rod 3 farthest from the wiper rod 2. The handle sleeve 92 is specifically a non-slip soft rubber handle made of soft rubber material. Anti-slip grooves 91 may also be provided on the outer wall to help the user better hold the adjustment rod 3.

[0074] Further, in this embodiment, please refer to Fig. 9 and Fig.10, and further includes a threaded sleeve 8; two adjacent adjustment rods 3 are threadedly connected via the threaded sleeve 8. The design of the threaded sleeve 8 not only enables the two adjustment rods 3 to be connected in series, better meeting the user's need for adjusting the length of the telescopic wiper, but also has the advantage of convenient assembly and disassembly, so that the user can quickly assemble the adjustment rods 3, which is conducive to increasing the convenience of using the telescopic wiper.

[0075] More specifically, the outer wall of the threaded sleeve 8 is provided with anti-slip grooves 91 to facilitate the user to hold and rotate the sleeve for installation.

[0076] Further, in this embodiment, please refer to Fig. 9 and Fig.10 A stopper 81 is provided inside the threaded sleeve 8. The stopper 81 can play a positioning role on the one hand, so as to remind the user that the adjusting rod 3 and the threaded sleeve 8 have been installed in place, and on the other hand, the threaded sleeve 8 can be effectively divided into two sections, ensuring that the two adjusting rods 3 connected to the threaded sleeve 8 have sufficient length to be stably connected to the threaded sleeve 8, which is conducive to ensuring the connection stability between the threaded sleeve 8 and the adjusting rod 3, and avoiding the phenomenon that the two adjusting rods 3 fall off during use.

[0077] More specifically, the limiting member 81 may be a limiting ring or a limiting plate arranged on the inner wall of the threaded sleeve 8. Both the limiting ring and the limiting plate can play the role of separating the two threaded sleeves. The middle of the limiting ring is provided with an opening, which is conducive to appropriately reducing the weight of the telescopic wiper.

[0078] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0079] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
