Technical Field

[0001] This utility model relates to the field of walking massager technology, and in particular to a walking massage mechanism with adjustable guide rail and toothed rail lengths. Background Technology

[0002] There is a Chinese utility model patent published on September 24, 2024, with announcement number CN221751350U: a walking massage mechanism that drives two double-headed massagers to swing while a single servo drive motor drives the entire massager to move back and forth along a linear guide rail.

[0003] However, the toothed rail and linear guide rail of this walking massage mechanism are quite long and are a single long strip that cannot be separated or adjusted in length. As a single long strip, the toothed rail and linear guide rail are prone to breakage and damage during production and transportation. In addition, when a part of the toothed rail or linear guide rail is damaged during use, the entire toothed rail or linear guide rail needs to be replaced, which will result in a waste of materials. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a walking massage mechanism with adjustable guide rail and toothed rail lengths, which solves the problem that the lengths of the existing toothed rail and linear guide rail are not adjustable, and that when a part is damaged, the entire toothed rail and linear guide rail need to be replaced, resulting in material waste.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a walking massage mechanism with adjustable guide rail and toothed rail lengths, including a housing, with a toothed rail and a guide rail or two toothed rails slidably connected below the housing, the toothed rail including at least two detachably fixedly connected racks, and the guide rail including at least two detachably fixedly connected sliders.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0025] like Figure 1 As shown, this utility model provides a walking massage mechanism with adjustable guide rail and toothed rail lengths, including a housing 1. A toothed rail 2 and a guide rail 3 or two toothed rails 2 are slidably connected below the housing 1 (this application uses one toothed rail 2 and one guide rail 3 as an example for description. In use, the toothed rail 2 and the guide rail 3 are fixed in a slotted housing, and the housing 1 slides along the toothed rail 2 and the guide rail 3 in the housing). The toothed rail 2 includes at least two detachably fixedly connected toothed racks 21, and the guide rail 3 includes at least two detachably fixedly connected slides 31. The material of the toothed racks 21 and the slides 31 is POM.

[0026] By setting multiple detachable and fixedly connected racks 21 and slides 31, when a part of the rack 2 or guide rail 3 is damaged during production, transportation, or use, the corresponding rack 21 or slide 31 can be disassembled and replaced individually. This avoids the need to replace the entire rack 2 or guide rail 3 when a part of the existing long rack 2 or guide rail 3 is damaged, thus avoiding material waste. At the same time, racks 2 and guide rails 3 of different lengths can be assembled according to different lengths of housings, avoiding the trouble of producing racks 2 and guide rails 3 of various lengths.

[0027] like Figures 2-7 As shown, the rack 21 and the slide bar 31 are provided with at least one set of fixing mechanisms. The fixing mechanisms include positioning components for positioning two adjacent racks 21 and two adjacent slide bars 31, and locking components for fixing two adjacent racks 21 and two adjacent slide bars 31.

[0028] The specific implementation methods of the fixing mechanism can be referred to in the following three embodiments:

[0029] Example 1:

[0030] like Figure 2 and Figure 3 As shown, the positioning assembly includes a positioning block 4 located at one end of the top surface of the rack 21 and the slide bar 31, and a positioning groove 5 located at the other end of the top surface of the rack 21 and the slide bar 31. The bottom surface of the positioning block 4 is at the same height as the bottom surface of the inner wall of the positioning groove 5, ensuring that when the two racks 21 and the two slide bars 31 are spliced ​​and fixed together, they are on the same straight line, thereby ensuring that the housing 1 can slide along the rack 2 and the guide rail 3. The locking assembly is a screw. The top surface of the positioning block 4 is provided with a first threaded hole adapted to the screw, and the bottom surface of the inner wall of the positioning groove 5 is provided with a second threaded hole adapted to the screw.

[0031] Taking slide bar 31 as an example: When it is necessary to assemble guide rail 3, the positioning block 4 on one slide bar 31 is snapped into the positioning groove 5 of another slide bar 31 from top to bottom, and then a screw is used to make it pass through the first threaded hole of the positioning block 4 and enter the second threaded hole, thereby completing the locking and fixing of the positioning block 4, that is, completing the quick fixing of two adjacent slide bars 31, so that when a slide bar 31 is damaged during the use of the massage mechanism, it is convenient to disassemble and replace it separately;

[0032] Figure 2 and Figure 3 Two sets of fixing mechanisms are set here, so that when the positioning block 4 of one slide bar 31 is located in the positioning groove 5 on the other slide bar 31, the positioning block 4 on the other slide bar 31 simultaneously enters the positioning groove 5 of one slide bar 31, making the fixing more stable.

[0033] Example 2:

[0034] like Figure 4 and Figure 5 As shown, the positioning assembly includes a positioning block 4 located at one end of the top surface of the rack 21 and the slide bar 31, and a positioning groove 5 located at the other end of the top surface of the rack 21 and the slide bar 31. The bottom surface of the positioning block 4 is at the same height as the bottom surface of the inner wall of the positioning groove 5. The locking assembly consists of a plastic locking block 6 and a first locking groove 7. The outer wall of the positioning block 4 is provided with several first locking grooves 7, and the inner wall of the positioning groove 5 is provided with several plastic locking blocks 6 that are adapted to the first locking grooves 7. The side of the plastic locking block 6 facing the groove opening of the positioning groove 5 is set as an inclined surface or arc surface that is inclined towards the center of the bottom surface of the positioning groove 5 (an inclined surface is used as an example for explanation here). When the plastic locking block 6 is located in the first locking groove 7, the side of the plastic locking block 6 facing the first locking groove 7 abuts against and fits against the inner wall of the first locking groove 7, ensuring that the positioning block 4 is stably fixed in the positioning groove 5.

[0035] Taking rack 21 as an example: When rack 2 needs to be assembled, the positioning block 4 on one rack 21 is inserted from top to bottom into the positioning groove 5 of another rack 21. Due to the existence of the inclined surface of the plastic locking block 6, the positioning block 4 can easily enter the positioning groove 5, and the plastic locking block 6 gradually deforms until the positioning block 4 is completely inserted into the positioning groove 5. At this time, the plastic locking block 6 is completely inserted into the first locking groove 7, and the plastic locking block 6 returns to its original length and abuts against the first locking groove 7, thereby ensuring that the positioning block 4 will not easily fall out of the positioning groove 5, so that the positioning block 4 is stably fixed in the positioning groove 5.

[0036] Meanwhile, to facilitate the separation of two adjacent racks 21, the bottom surface of the plastic block 6 facing the inner wall of the positioning groove 5 is also designed as an inclined surface or arc surface that slopes towards the center of the bottom surface of the positioning groove 5. The two inclined surfaces are in the shape of an "eight", so that the positioning block 4 can be easily removed from the positioning groove 5 without much force. Thus, when a rack 21 is damaged during the use of the massage mechanism, it is convenient to disassemble and replace it separately.

[0037] Example 3:

[0038] like Figure 6 and Figure 7 As shown, the positioning component includes an insert 11 located at one end of the rack 21 and the slide 31, and a slot 12 located at the other end of the rack 21 and the slide 31 that is adapted to the insert 11. The bottom surface of the insert 11 is at the same height as the bottom surface of the inner wall of the slot 12. The locking component includes a plastic retaining strip 101 and a second retaining groove 91. A support plate 10 is provided at the opening of the slot 12. At least one plastic retaining strip 101 parallel to the opening of the slot 12 is provided on the second support plate 10. A groove 9 adapted to the support plate 10 is opened on the bottom or top surface of the rack 21 and the slide 31 near the end of the insert 11. A second retaining groove 91 adapted to the plastic retaining strip 101 is opened on the inner wall of the groove 9.

[0039] Taking rack 21 as an example: When rack 2 needs to be assembled, insert the plug 11 at one end of one rack 21 into the slot 12 of another rack 21. As the plug 11 gradually enters the slot 12, the top surface of the support plate 10 fits against the bottom surface of the inner wall of the groove 9. Subsequently, the plastic retaining strip 101 is gradually squeezed and deformed until the plug 11 is completely inserted into the slot 12. At this time, the plastic retaining strip 101 returns to its original length and enters the second retaining groove 91, thereby ensuring that the plug 11 will not easily fall out of the slot 12.

[0040] The plastic retaining strip 101 and the second retaining groove 91 are designed to be arc-shaped, so that when it is necessary to disassemble adjacent racks 21, it is not necessary to use too much force to separate the two adjacent racks 21.

[0041] like Figure 4 and Figure 5 As shown, based on Embodiment 2, the size of the positioning block 4 is smaller than the size of the positioning groove 5. The outer wall of the positioning block 4 is provided with several protrusions 8. When the positioning block 4 on one rack 21 or slide 31 is located in the positioning groove 5 of another rack 21 or slide 31, the protrusions 8 do not contact the inner wall of the positioning groove 5.

[0042] By setting the positioning block 4 to be smaller than the positioning groove 5, and when the positioning block 4 is located inside the positioning groove 5, the protrusion 8 does not contact the inner wall of the positioning groove 5. This assembly gap facilitates the quick positioning and placement of the positioning block 4, and also facilitates the installation of the plastic clip 6. It can also relatively increase the size of the plastic clip 6, so that the plastic clip 6 is more stably located inside the first slot 7 and presses against the inner wall of the first slot 7, i.e., the positioning block 4, making the two adjacent racks 21 and slides 31 more stably fixed.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
