Description

The composite set of ceiling fan blade and leaf frame

The utility model relates to the composite set of a kind of ceiling fan blade and leaf frame.

Fan is a kind of ventilation heat extraction device that all can see in every household, company of factory, and the fan that generally hangs on the ceiling board can be referred to as ceiling fan.More and more be particular about today of quality of the life and graceful environment at everybody, ceiling fan is ventilation equipment no longer just, appearance and pattern are much accounted of more, the main points of consideration when everybody buys especially with the leaf frame of ceiling fan blade on the market at present, so the dealer often separates to make to go with blade and leaf frame again and cooperates, make its pattern, appearance has the matched combined of more differences, and its compound mode can be as Fig. 1,2,3, shown in 4, on leaf frame 10, set up earlier the cylinder 121 of three tool screws 12, and establish three perforation 13 in blade 11 corresponding screws 12 places and be locked together in one by one in the screw 12 by three screw 14 injection perforation 13, blade 11 ' and leaf frame 10 can be fitted together, but so structure has following shortcoming and inconvenience, such as:

1. the inconvenience when assembling, dismounting

Because of wanting sealed three screws 14 simultaneously; can finish assembling; also will unclamp three screws 14 during dismounting simultaneously could clean; the one group of ceiling fan that so moves just has five blades totally ten five screws; usually have the problem of omitting screw, moreover each blade 11 also there is the puzzlement that must align screw 12 when Locking screw 14.

2. its sealed power is not strong

Ceiling fan be hang on the ceiling board so its adhesive strength is paid attention to part most, blade 11 and leaf frame 10 combine as only depends on screw 14 and screw 12 sealed its when normal use of a specified duration, will unavoidably get loose because of factors such as vibration cause.

Because aforementioned ceiling fan blade and leaf frame its when assembling, dismounting, still have its desirable not to the utmost part, when using and assemble, exist many puzzlements with inconvenient, so have much room for improvement.

The purpose of this utility model is to provide the composite set of a kind of ceiling fan blade and leaf frame, can improve the speed and the convenience of assembling, dismounting, must align the puzzlement of screw when avoiding screw to cause omission and assembling too much with screw, and the sealed power between raising ceiling fan blade and the leaf frame, increase its structural strength and Security.

The technical solution of the utility model is, the composite set of a kind of ceiling fan blade and leaf frame is provided, comprise a leaf frame and a blade, be provided with at least three perforation in blade, the corresponding lower end that is provided with the perforation of cylinder insertion blade on the leaf frame, the another side that differs from blade and leaf frame junction plane on the blade is provided with an arc spring sheet, and be provided with two recessed posts in location in the arc inboard of spring sheet, this recessed post in two location inserts biperforate upper end corresponding on the blade, establish a perforation in two location one of recessed posts sides, the cylinder that passes tool screw on the perforation of spring sheet and corresponding blade perforation and the leaf frame with a helicoid knob screws togather fixing.

The composite set of described ceiling fan blade and leaf frame, its knob form a larger-diameter embossing face in the other end that is provided with screw thread.

Effect of the present utility model is:

1, can improve the speed and the convenience of the assembling of assembling ceiling fan, dismounting, keep away the look screw and cause the puzzlement of omitting and screw must be aligned screw too much.

2, the sealed power of ceiling fan blade and leaf frame be can improve, its adhesive strength and Security increased.

3, can exempt to use instrument, can be sealed, dismounting blade and leaf frame, make it more convenient.

The accompanying drawing drawing is described as follows:

Fig. 2 is traditional ceiling fan blade and leaf frame constitutional diagram.

Fig. 3 is traditional ceiling fan blade and sealed plan view of leaf frame.

Fig. 4 A is the A-A sectional view of Fig. 3.

Fig. 4 B is the B portion partial enlarged drawing of Fig. 4 A.

Fig. 5 is ceiling fan blade of the present utility model and leaf frame three-dimensional exploded view.

Fig. 6 is ceiling fan blade of the present utility model and leaf frame constitutional diagram.

Fig. 7 is ceiling fan blade of the present utility model and the sealed sectional drawing of leaf frame.

Fig. 8 is ceiling fan blade of the present utility model and the sealed profile of leaf frame.

Embodiment shown in the utility model is incited somebody to action in conjunction with the accompanying drawings is described in further detail as follows:

As Fig. 5, Fig. 6, Fig. 7, shown in Figure 8, ceiling fan blade of the present utility model and leaf frame assembly, comprise blade 11, leaf frame 10, leaf frame 10 is provided with three cylinders 121, correspondence is provided with three perforation 13 on the blade 11, blade 11 is positioned on the leaf frame 10 and three cylinders 121 on the leaf frame 10 are snapped in end under blade 11 perforation 13, locate in advance, one spring sheet 15 is set on blade 11 again, utilize two recessed posts 16 in location of spring sheet 15 times to be placed in two perforation 13 upper ends on the blade 11, it is sealed to run through the cylinder 121 of tool screw 12 on perforation 13 and the leaf frame 10 on spring sheet 15 and the blade 11 by the knob 17 of a tool screw thread again, make the recessed post 16 in location in blade perforation 13, have distance suitably to touch mutually in sealed Hou is unlikely with cylinder 121 on the corresponding leaf frame 10,2 on mat is located automatically, some locking, make it become the location, three summits of isosceles triangle, to promote assembling, speed during dismounting and convenience, avoid screw to cause omission and screw to align the puzzlement of screw too much, spring sheet 15 makes it become the aspect of a tool arc during fabrication in addition, it just can be because of its profile institute elastic force of formation naturally when sealed, bring into play the effect of two end brute forces against blade 11, the more danger that can therefore avoid knob 17 to get loose and caused, the effect of performance resilient pad, make blade 11 and the sealed power and the adhesive strength thereof of leaf frame 10 increase, moreover for making things convenient for the user can also can be sealed under no instrument, dismounting blade 11 and leaf frame 10, its knob 17 removes screw thread and partly partly enlarges its diameter at screw terminal especially, and in the diameter surface embossing, embossing allows the user can singlehandedly easily become flexible knob 17.
