BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a partial perspective view of a fixed structure of the present invention.

2 is an exploded perspective view of the fixed structure shown in FIG. 1.

Figure 3 is a schematic cross-sectional view of Figure 1 taken along the line III-III.

The fixing structure of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

Referring to FIG. 1 , a fixing structure 100 according to a preferred embodiment of the present invention includes a barrel 40 and a fixing cover 20 fixed to one end of the barrel 40 . A battery (not shown) can be received within the barrel 40 and abutted against the stationary cover 20. The fixed structure 100 can be applied to electronic devices such as a wireless keyboard, a wireless touch panel, and a remote controller.

Referring to FIG. 2 , the fixing cover 20 includes a cylindrical fixing portion 21 and a circular cover 22 provided at one end of the fixing portion 21 . The fixing portion 21 is housed in the cylindrical body 40. Two receiving grooves 211 and two limiting portions 213 are symmetrically disposed on the side wall of the fixing portion 21 . The two limiting portions 213 are symmetric with each other and adjacent to the accommodating groove 211. The fixing portion 21 is provided with two elastic holding members 23, and the two elastic holding members 23 are respectively received in the receiving grooves 211. The diameter of the cover 22 is slightly larger than the fixed portion The diameter of 22 is such that the cover 22 is resisted outside the barrel 40.

Each of the elastic retaining members 23 includes a sleeve 231 that is closed at one end, a spring 233 that is received in the sleeve 231, and a retaining portion 235 that is slidably mounted on the sleeve 231.

The sleeve 231 has an opening 2311 that is slightly gathered inwardly so that the catching portion 235 is received in the sleeve 231 and is difficult to escape from the opening 2311. The sleeve 231 can be fixed in the receiving groove 211 of the fixing portion 21 by adhesive or screwing. The opening 2311 can be formed by shrink forming a mold.

The spring 233 has a generally cylindrical shape with an outer diameter slightly smaller than the inner diameter of the sleeve 231, so that the spring 233 can slide within the sleeve 231.

The retaining portion 235 includes a cylindrical base body 2351 and a circular abutting flange 2352 extending from one end of the base body 2351. The diameter of the base body 2351 is larger than the diameter of the abutting flange 2352, and is slightly smaller than the diameter of the sleeve 231, so that the base body 2351 slides in the sleeve 231, and the abutting flange 2352 extends out of the sleeve 231.

The inner wall 41 of the cylinder 40 is symmetrically provided with two latching portions 42 corresponding to the limiting portion 213 and two engaging portions 43 corresponding to the latching portions 235 of the elastic retaining member 23. Specifically, in this embodiment, each of the stopping portions 42 is a groove extending from the open end of the tubular body 40 toward the inside of the tubular body 40 , and each of the engaging portions 43 is adjacent to the opening portion 42 and away from the opening of the tubular body 40 . The groove is set at the end. Each of the stopping portions 42 includes a guiding side wall 422 extending obliquely with respect to the axial direction of the cylindrical body 40, and an arcuate side wall 423 adjacent to the engaging portion 43. The engaging portion 43 includes a curved bottom wall 431 and two opposite abutting sidewalls 433 extending circumferentially of the cylinder 40. The abutting flange 2352 of the retaining portion 235 of the elastic retaining member 23 can slide into the engaging portion 43 from the stopping portion 42 and abut against the abutting side wall 433 of the engaging portion 43. The limiting portion 213 of the fixing cover 20 can slide into the stopping portion 42.

In order to facilitate the assembly operation, a cover-shaped operation slot 221 is further defined in the radial direction of the cover body 22, and the fixed cover 20 can be assembled to one end of the cylinder 40 by a tool such as a screwdriver (not shown).

Referring to FIGS. 2 and 3, when the battery is fixed, first, the battery is loaded into the cylinder 40. Then, the two holding portions 235 are correspondingly slid into the stopper portions 42 of the two cylinders 40. Finally, the fixing cover 20 is rotated, the locking portion 235 compresses the spring 233 and slides into the engaging portion 43 and abuts against the abutting side wall 433 of the engaging portion 43. Meanwhile, the limiting portion 213 slides into the stopping portion 42. Moreover, the arcuate side wall 423 of the stopper portion 42 is pressed to limit the holding portion 235, and finally the battery is fixed in the cylindrical body 40.

When the battery is disassembled, first, the fixed cover 20 is rotated in the reverse direction, and the catching portion 235 compresses the spring 233 and slides into the stopper portion 42 from the engaging portion 43. Next, the fixing cover 20 is taken out, and the holding portion 235 is disengaged from the stopper portion 42. Finally, the battery is removed from the barrel 40.

The fixing structure 100 is detachably held by the elastic holding member 23 of the fixing cover 20 and the engaging portion 43 of the cylinder 40, thereby fixing the battery in the cylinder 40, and the structure is simple and the battery is convenient to be fixed or disassembled. .

It can be understood that the receiving groove 211 of the fixing cover 20 and the corresponding elastic holding member 23, the corresponding stopping portion 42 and the engaging portion 43 of the cylindrical body 40 are not limited to two, and may be one or two or more. The stop portion 42 is not limited to a groove disposed adjacent to the stop portion 42 and away from the open end of the tubular body 40, and may be other structures. For example, the stop portion 42 may also be an "L" type limit rib. The seat portion 213 slides along one side of the limiting rib and is stopped by the other side. The engaging portion 43 is not limited to a groove disposed adjacent to the opening portion 42 and away from the open end of the tubular body 40. It may also be other structures. For example, the engaging portion 43 may also be a "ㄈ" type engaging rib, which is elastic. The catching portion 235 of the holding member 23 can be engaged with the engaging rib. The sleeve 231 of the elastic holding member 23 can be omitted. At this time, the spring 233 and the holding portion 235 are directly accommodated in the receiving portion. In the slot 211, the opening of the receiving slot 211 is a cutout. In addition, the elastic retaining member 23 is not limited to being slid into the engaging portion 43 from the stopping portion 42, and the elastic retaining member 23 can be slid into the engaging portion and can be engaged therewith.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the spirit of the invention are intended to be included within the scope of the following claims.
