Description

Technical Field

[0001] The present application relates to the technical field of micro-needle application appliances, and in particular, to a variable-spacing roller mounting fork and a soluble micro-needle massager. Background Art

[0002] The micro-needle massager uses many tiny needles on the micro-needle roller to stimulate the skin, enabling active ingredients to effectively penetrate the skin. When used in combination with special-effect products such as anti-wrinkle, whitening, repair, stretch mark removal, and scar removal products, it can achieve ideal effects such as reducing wrinkles, treating scars and stretch marks, skin whitening, reducing age spots, improving eye wrinkles, dark circles, tightening and lifting facial skin tissues, etc.

[0003] After retrieval, a Chinese patent with the application number 202120956489.5 discloses a soluble micro-needle massager, which includes a handle, a massage roller, and a soluble micro-needle patch. One end of the handle is provided with a fork portion, the massage roller is rotatably mounted on the fork portion, the soluble micro-needle patch includes a substrate and micro-needles, and the substrate is bonded to the outer peripheral wall of the massage roller, wherein the massage roller is mainly detachably mounted on the fork portion by a clamping method.

[0004] Regarding the above related technologies, the inventor believes that there are the following technical defects to be improved:

[0005] For different user groups and different skin massage positions, massage rollers of different lengths are generally required, so different sizes of handles need to be customized to ensure that the installation gap width of the fork portion matches the length of the corresponding massage roller, that is, the same handle can only be adapted to a massage roller of the same size. However, customizing fork portions with different installation gap widths requires a large amount of mold opening costs, indirectly resulting in a higher production cost of the product. Summary of the Utility Model

[0006] The present application provides a variable-spacing roller mounting fork and a soluble micro-needle massager to improve the following technical problems:

[0007] The same handle can only be adapted to a massage roller of the same size. However, customizing fork portions with different installation gap widths requires a large amount of mold opening costs, indirectly resulting in a higher production cost of the product.

[0008] In the first aspect, the present application provides a variable-spacing roller mounting fork, adopting the following technical solution:

[0009] A variable-spacing roller mounting fork includes a fork base and two sliding fork plates. The two sliding fork plates are vertically and slidably assembled on the same side of the fork base. A variable-width roller mounting gap is formed between the two sliding fork plates. A set of elastic driving units are respectively arranged at both ends of the fork base, and the elastic driving units are used to drive the sliding fork plates to slide horizontally inward.

[0010] In an implementable technical solution of the present application, a chute is provided on the upper surface of the fork base, and a sliding block is provided at the bottom of the sliding fork plate. The sliding block freely slides in the chute.

[0011] In an implementable technical solution of the present application, the sliding block and the chute are of a mutually adapted inverted T-shaped structure or dovetail-shaped structure.

[0012] In an implementable technical solution of the present application, the elastic driving unit includes an end plate and a strong spring. The outer end of the chute penetrates through the side of the fork base. The end plate is detachably and fixedly assembled on the side of the fork base. The strong spring is installed in the chute and arranged horizontally. One end of the strong spring is fixed to the inner side of the end plate, and the other end of the strong spring abuts against the sliding block. The elastic force of the strong spring drives the sliding block to slide inward.

[0013] In an implementable technical solution of the present application, both the end plate and the strong spring are stainless steel parts, and the end plate and the strong spring are fixedly welded.

[0014] In an implementable technical solution of the present application, a locking bolt is provided between the end plate and the fork base. The locking bolt penetrates through the end plate and is threadedly assembled on the side of the fork base.

[0015] In an implementable technical solution of the present application, a sink for accommodating the cap part of the locking bolt is provided on the outer side surface of the end plate.

[0016] In a second aspect, the present application provides a soluble microneedle massager, adopting the following technical solution:

[0017] A soluble microneedle massager includes a handle, a massage roller and a soluble microneedle patch. The soluble microneedle patch is bonded to the outer peripheral wall of the massage roller. The variable-spacing roller mounting fork as described above is arranged at the end of the handle, and the massage roller rotates and is clamped in the variable-spacing roller mounting fork.

[0018] In an implementable technical solution of the present application, arc-shaped grooves for adapting to finger clamping are provided on both sides of the handle.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] Use force to pry the two sliding fork plates outward to increase the roller installation gap, and then put the massage roller between the two sliding fork plates. Driven by the elastic force of the elastic drive unit, the two sliding fork plates slide horizontally inward and the roller installation gap becomes smaller until the massage roller is clamped (without affecting the rotation of the massage roller). This allows adaptation to massage rollers of various lengths and sizes, without the need to customize many installation forks with different installation gap widths, saving a lot of mold opening costs and indirectly reducing the production cost of the product.

[0034] The following further describes the present application in detail with reference to the Figures 1-3 accompanying drawings.

[0035] An embodiment of the present application discloses a variable-spacing roller mounting fork 400. Referring to Figure 1 and Figure 2 , the variable-spacing roller mounting fork 400 includes a fork base 41 and two sliding fork plates 42. The two sliding fork plates 42 are vertically and slidably assembled on the same side of the fork base 41. A roller mounting gap with a variable width is formed between the two sliding fork plates 42. A set of elastic driving units 43 are respectively arranged at both ends of the fork base 41. The elastic driving units 43 are used to drive the sliding fork plates 42 to slide horizontally inward.

[0036] In this embodiment, in order to facilitate the stable sliding of the sliding fork plate 42, a sliding groove 411 is provided on the upper surface of the fork base 41, and a sliding block 421 is provided at the bottom of the sliding fork plate 42. The sliding block 421 freely slides in the sliding groove 411, wherein the sliding block 421 and the sliding groove 411 are of a mutually adapted inverted T-shaped structure or dovetail-shaped structure.

[0037] In this embodiment, the elastic driving unit 43 includes an end sealing plate 431 and a strong spring 432. The outer end of the slide groove 411 passes through the side of the fork base 41. The end sealing plate 431 is detachably fixedly assembled on the side of the fork base 41. The strong spring 432 is installed in the slide groove 411 and arranged horizontally. One end of the strong spring 432 is fixed to the inner side surface of the end sealing plate 431, and the other end of the strong spring 432 abuts against the sliding block 421. The elastic force of the strong spring 432 drives the sliding block 421 to slide inward.

[0038] The end sealing plate 431 and the strong spring 432 are both made of stainless steel, and are fixed by welding.

[0039] A locking bolt 433 is provided between the end sealing plate 431 and the fork base 41. The locking bolt 433 passes through the end sealing plate 431 and is threadedly assembled on the side of the fork base 41. In order to prevent the locking bolt 433 from protruding from the outer side surface of the installation fork, a recessed groove 4311 for accommodating the cap of the locking bolt 433 is provided on the outer side surface of the end sealing plate 431.

[0040] The elastic drive unit 43 designed as above has a simple structure and is easy to install, and can stably drive the sliding fork plate 42 to slide horizontally to clamp the massage roller in the roller installation gap.

[0041] Combination Figure 3 The beneficial technical effects of the variable spacing roller mounting fork 400 of the embodiment of the present application are roughly as follows:

[0042] Use force to pry the two sliding fork plates 42 outwards to increase the roller installation gap, and then put the massage roller 200 between the two sliding fork plates 42. Driven by the elastic force of the elastic drive unit 43, the two sliding fork plates 42 slide horizontally inwards, and the roller installation gap becomes smaller until the massage roller 200 is clamped (without affecting the rotation of the massage roller 200). This allows the massage rollers 200 of various lengths to be adapted, without the need to customize many installation forks with different installation gap widths, thereby saving a lot of mold opening costs and indirectly reducing the production cost of the product.

[0043] The present application embodiment discloses a soluble microneedle massager, referring to Figure 1 and Figure 3 The soluble microneedle massager includes a handle 100, a massage roller 200 and a soluble microneedle patch 300. The soluble microneedle patch 300 is bonded to the outer peripheral wall of the massage roller 200. The variable spacing roller mounting fork 400 as mentioned above is arranged at the end of the handle 100. The massage roller 200 rotates and is clamped in the variable spacing roller mounting fork 400.

[0044] In order to facilitate the user to grip tightly, arc-shaped grooves 11 for adapting to finger clamping are provided on both sides of the handle 100.

[0045] The above are only the preferred embodiments of the present application, and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the application shall be included within the protection scope of the present application.
