[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0028] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0029] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0030] like Figure 1-5 The example shown is an embodiment provided by the utility model.
[0031] The embodiment of the utility model provides a telescopic arm, including: a fixed arm 10 and a movable arm 20, the upper end of the fixed arm 10 is used to connect to the main body shell of the massager, the upper end of the movable arm 20 is inserted into the lower end of the fixed arm 10, the movable arm 20 is usually flat and long, and has a certain curvature, and its material usually has a certain elasticity, which can support the movable arm 20 to bend to a certain extent. Specifically, a limit frame 11 and two locks 12 are set in the fixed arm 10, the cross section of the limit frame 11 is similar to an inverted U shape, the limit frame 11 is buckled on the inner wall of the fixed arm 10, and is enclosed with the inner wall of the fixed arm 10 to form a slide rail, the width and depth of the slide rail are adapted to the movable arm 20, the movable arm 20 is slidably connected in the slide rail, and the slide rail forms a limit on the circumference of the movable arm 20 to prevent the movable arm 20 from shaking, so that the movable arm 20 can only slide back and forth along its own axis direction, that is, the length direction of the slide rail. Two lock buckles 12 are symmetrically arranged on both sides of the movable arm 20. The two lock buckles 12 sandwich the movable arm 20 in the middle, further limiting the two sides of the movable arm 20. The lower ends of the two lock buckles 12 are provided with limiting posts 121. Correspondingly, the two side walls of the movable arm 20 are symmetrically distributed with a number of limiting grooves 21. The limiting posts 121 are movably engaged with the limiting grooves 21, and can limit the sliding of the movable arm 20. The end of the limiting post 121 can be set to a hemispherical head shape. Correspondingly, the limiting groove 21 can be set to a half-shaped groove or a long groove with a semicircular cross-section, so that the connection between the limiting post 121 and the limiting groove 21 is smoother. When the limiting post 121 is separated from the limiting groove 21, the limit of the sliding of the movable arm 20 disappears, and the movable arm 20 can be freely extended and retracted in the fixed arm 10. Furthermore, a number of limit grooves 21 are equidistantly distributed, and the distance between each limit groove 21 can be set according to the user's adjustment habits. When the limit column 121 is snapped into the limit groove 21, the circumferential and axial directions of the movable arm 20 are fixed, and are not prone to loosening, which can adapt to long-term and frequent use.
[0032] Specifically, a movable top block 13 is provided on the limiting frame 11, and reverse slopes 131 are respectively provided on both sides of the bottom of the movable top block 13, and a slope 123 is provided on the upper end of the lock buckle 12. The reverse slopes 131 on both sides of the bottom of the movable top block 13 are simultaneously slidably abutted with the slopes 123 on the upper ends of the two lock buckles 12. The movable top block 13 moves up and down to drive the two lock buckles to move away from or close to each other, so that the limiting column 121 is engaged or separated from the limiting groove 21. Specifically, the slope 123 and The angle of the reverse slope 131 is between 30° and 60°, and the angles between the two are complementary. The best angle is 45° for the slope 123 and the reverse slope 131. When the movable top block 13 moves downward, the two lock buckles 12 are squeezed outward at the same time until the reverse slope 131 at the bottom of the movable top block 13 is separated from the slope 123 at the upper end of the lock buckle. The two lock buckles move outward at the same time, so that the limiting column 121 at the lower end of the lock buckle 12 is separated from the limiting groove 21 at the same time until they are completely separated. The outer side wall of the lower end of the lock buckle 12 is provided with a first return spring 122, and the outer end of the first return spring 122 abuts against the inner wall of the fixed arm 10. When the lower end of the lock buckle 12 moves outward, the first return spring 122 accumulates elastic force. When the downward pressure of the movable top block 13 is released, the first return spring 122 can make the lock buckle move inward close to the movable arm 20, restore the state of the limit column 121 and the limit groove 21, and provide a pre-tightening force for the connection between the two to prevent the limit column 121 from loosening from the limit groove 21. More specifically, the bottom of the movable top block 13 is provided with a second return spring 132, and the lower end of the second return spring 132 abuts against the limit frame 11. The second return spring 132 can push the movable top block 13 upward to return to its original position after the downward pressure of the movable top block 13 is released, so as to facilitate pressing again. The upper end of the top block is connected with a button 133 , and the upper end of the button 133 passes through the fixed arm 10 , so that the user can press the movable top block 13 from the outside to control the movable state of the movable arm 20 .
[0033] Furthermore, two baffles 14 are provided in the fixed arm 10 , and the two baffles 14 are respectively abutted against two sides of the movable arm 20 . The two baffles 14 serve to extend the length of the slide rail, and can further prevent the movable arm 20 from shaking left and right during the sliding process.
[0034] Furthermore, a limiting portion 22 is provided at the upper end of the movable arm 20, and the limiting portion 22 is used to prevent the movable arm 20 from falling off from the fixed arm 10. Specifically, the limiting portion 22 is a protrusion respectively provided on the top wall and the bottom wall of the movable arm 20, and can abut against the upper end of the limiting frame 11 when the movable arm 20 extends out of the fixed arm 10 to reach the longest length, thereby preventing the movable arm 20 from further sliding out of the range of the slide rail and causing the movable arm 20 to fall off.
[0035] The embodiment of the utility model further provides a massager, comprising a massage main body and two telescopic arms, wherein the two telescopic arms are symmetrically arranged at two ends of the massage main body.
[0036] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive. Although the utility model is described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the aforementioned specific implementation methods, or to replace some of the technical features therein with equivalents.
