Detailed Description

By integrating the above technical features, the main functions of the insert type reel fixing device of the present invention will be clearly demonstrated in the following embodiments.

Referring to fig. 1 to 3, a first combination of the reel according to the present invention is disclosed, in which a tab type reel fixing device of the present invention is combined with a reel body 1 to form the reel (the reel body 1 is shown in fig. 9). The reel body 1 comprises a manual control assembly 11. This inserted sheet formula spool fixing device contains: a wheel cap 2, a cover 3, a fixing frame 4 and a plug 5, wherein the cover 3 has a first radial direction D1 and a second radial direction D2, and the wheel cap 2 has a third radial direction D3 and a fourth radial direction D4.

The wheel cap 2 is coupled to the control assembly 11 to replace the original bead cover. The wheel cap 2 has a first cylinder 21, a plurality of concave holes 22 adjacent to each other, a first indicator 23 and a second indicator 24. The first tube 21 extends toward the reel body 1, and the first tube 21 has a first coupling portion 211 and two first grooves 212. The concave hole 22 and the first groove 212 are disposed on the third radial direction D3 and the fourth radial direction D4. The first coupling portion 211 is a concave strip, the first groove 212 is a semi-cylindrical groove, the first indicator 23 is in the shape of TOP, and the second indicator 24 is in the shape of WALL, but the invention is not limited thereto.

The outer cover 3 is combined with the wheel cap 2 and has a carrying portion 31, a second cylindrical portion 32, a window 33, a limiting wall 34 and a second groove 35. The carrier 31 has a first width in the first radial direction D1 and a second width in the second radial direction D2. The wheel cap 2, the limiting wall 34 and the carrying part 31 form a limiting space 36. The second groove 35 penetrates the cover 3 and is semi-cylindrical on the second cylinder 32, and is exactly combined with the first groove 212 of the wheel cap 2 to form a complete cylinder for a self-tapping screw 6 to pass through. The second tube portion 32 has a second coupling portion 321 which is a rib.

The fixing frame 4 has a fixing space 41 and a gap 43 adjacent to the two abutting surfaces 42, the gap 43 communicates with the fixing space 41, the width of the gap 43 is smaller than the maximum width of the fixing space 41, the first width is between the width of the gap 43 and the maximum width of the fixing space 41, and the second width is smaller than or substantially equal to the width of the gap 43.

Referring to fig. 2, 4 to 6 and 9, the fixing frame 4 is first fixed to a ceiling a on which the reel is to be mounted by screws, and the notch 43 of the fixing frame 4 is located below. When the wheel cap 2 is coupled to the control assembly 11 and the first radial direction D1 is aligned with the third radial direction D3, the window 33 of the outer cover 3 corresponds to the first indicator 23 of the wheel cap 2, i.e. the TOP word.

The second engaging portion 321 is engaged with the first engaging portion 211, and the tapping screw 6 taps into the second groove 35 and the first groove 212 on the third radial direction D3 to fixedly engage the wheel cap 2 with the outer cover 3. Rotating the outer cover 3 together with the reel body 1 to make the first radial direction D1 face upward to correspond to the notch 43 of the fixing frame 4. By the second width, the carrying portion 31 enters the fixing space 41 of the fixing frame 4 from the notch 43, and the fixing frame 4 extends into the limiting space 36.

Referring to fig. 2, 4 and 7 to 9, the outer cover 3 is rotated together with the reel body 1 again, so that the second radial direction D2 corresponds to the notch 43 of the fixing frame 4. By the first width, the carrying portion 31 is restricted by the fixing frame 4. In the axial direction of the reel body 1, the fixing frame 4 blocks the wheel cap 2 and the limiting wall 34 of the outer cover 3, so that the reel body 1 can be effectively limited in the axial direction of the reel body 1. Therefore, the outer cover 3 and the scroll body 1 can be combined on the fixing frame 4 by a single person, and the scroll can be mounted more conveniently and more quickly.

Finally, the inserting sheet 5 is inserted into the limiting space 36, and the two convex particles 51 of the inserting sheet 5 slide into and are clamped in the concave hole 22 on the fourth radial direction D4. At this time, a first side edge 52 of the inserting sheet 5 is correspondingly abutted against the carrying part 31, and a second side edge 53 of the inserting sheet 5 is correspondingly abutted against the abutting surface 42, so that the outer cover 3 can be reliably positioned without rotating by the blocking of the inserting sheet 5. Preferably, the top of the protruding element 51 has a gentle slope on the side close to the first side edge 52 and a steep slope on the side away from the first side edge 52, so as to facilitate the locking of the protruding element 51 in the recess 22 and prevent the protruding element 51 from easily sliding out of the recess 22.

Referring to fig. 10 to 13, which illustrate a second combination of the first embodiment of the reel, when the fixing frame 4 is horizontally disposed on a vertical wall surface B, the notch 43 of the fixing frame 4 is located at a side edge. Similarly, the wheel cap 2 is first coupled to the control assembly 11, and the first radial direction D1 and the fourth radial direction D4 are aligned, so that the window 33 of the outer cover 3 corresponds to the second indicator 24 of the wheel cap 2, i.e. the window shape, and the self-tapping screw 6 is tapped into the second groove 35 of the outer cover 3 and the first groove 212 of the fourth radial direction D4.

Referring to fig. 13 to 16, the subsequent assembly of the reel is similar to the first assembly state, the cover 3 is rotated together with the reel body 1 (the reel body 1 is shown in fig. 9), such that the first radial direction D1 faces to the notch 43 of the fixing frame 4, and the carrying portion 31 enters the fixing space 41 from the notch 43. The outer cover 3 is rotated together with the reel body 1 again, so that the second radial direction D2 corresponds to the notch 43 of the fixing frame 4, and the carrying portion 31 is restricted by the fixing frame 4 and cannot leave the fixing space 41 from the notch 43.

Finally, the inserting sheet 5 is inserted into the limiting space 36, and the convex particles 51 of the inserting sheet 5 slide into and are clamped in the concave holes 22 on the third radial direction D3. It should be noted that the window 33 corresponds to the same second indicator 24 whether the wall B is to the right or to the left of the wheel cap 2, but the insert 5 is on the side remote from the wall B.

Referring to fig. 17 and 18, a second embodiment of the reel is disclosed, which is different from the first embodiment in that: in the first embodiment, the control unit 11 is manual; in the present embodiment, the control unit 11a is electrically powered. As in the first embodiment, there may be a first combination state and a second combination state in order to correspond to the situation where the reel is installed on the ceiling a or the wall B (the ceiling a should be matched with fig. 4, the wall B should be matched with fig. 13), the wheel cap 2a is first combined with the control component 11a, the outer cover 3a is combined with the wheel cap 2a, the outer cover 3a is rotated to enable the carrying portion 31a to enter the fixing space 41a of the fixing frame 4a from the notch 43a, then the outer cover 3a is rotated to enable the carrying portion 31a not to fall out from the notch 43a, and finally the inserting piece 5a is inserted between the wheel cap 2a and the outer cover 3 a. The steps are not shown in detail in the drawings, but are described simply by words.

Synthesize the explanation of above-mentioned embodiment, as can fully understand the utility model discloses an operation, use and the efficiency that the utility model produced, above only the embodiment only does the preferred embodiment of the utility model, when can not with this inject the scope of the utility model implementation, all belong to the within range that the utility model discloses the range of applying for a patent and creating the description do simple equivalent change and modification promptly.
