Abstract
The utility model discloses a kind of double universal turbofan of Band clamp, including fan head and holder, the fan head is connected by universal joint with holder, the universal joint is a pair of ball head structure, with a body of rod, the both ends of the body of rod are respectively provided with bulb, and two bulb is rotatably connected with fan head and holder respectively.
Description
Technical field
The technical field of electric fan is the utility model is related to, refers in particular to a kind of fan of Band clamp.
Background technology
The fan of Band clamp, including fan head and holder, the fan head are connected by universal joint with holder, connect aft-fan
Head can carry out waving above and below left and right, adjust the angle of blowing, in the prior art, the universal joint using single ball head structure,
That is the first end of universal joint aspheric is fixed together with fan head, and bulb one end is flexibly connected with holder, or the universal joint
Bulb one end is flexibly connected with fan head, and the first end of aspheric is fixedly connected with holder, and fan can be all allowed after two ways connection
Head realizes waving above and below left and right, is rotated flexibly using this single ball head universal fan head, but rotation amplitude is little, in view of
This, the design people actively studies improvement and opened for not attaining many missings caused by improving and inconvenience in said structure design
Hair designs the utility model.
Utility model content
The purpose of this utility model is to provide a kind of double universal turbofan of Band clamp, it is possible to increase fan head amplitude of fluctuation
Degree.
For the above-mentioned purpose, the technical solution of the utility model is：A kind of double universal turbofan of Band clamp, including wind
Fan head and holder, the fan head are connected by universal joint with holder, and the universal joint is a pair of ball head structure, has a body of rod,
The both ends of the body of rod are respectively provided with bulb, and two bulb is rotatably connected with fan head and holder respectively.
The ball joint chair with universal joint bulb corresponding matching, the middle part of the ball joint chair are respectively equipped with the fan head and holder
The open chamber of a top surface is formed, two bulbs of universal joint are respectively implanted in two chamber, fixed by fixing nut, by two balls
Together with head is rotatably connected with ball joint chair.
Several breach are circumferentially molded in the opening of the chamber, and is thus circumferentially formed and is used for holding bulb tightly
Elastic arm.
The outside of the ball joint chair is provided with the external screw thread coordinated with fixing nut.
Using said structure, the universal joint that fan head and holder are connected due to the utility model uses double ball head structures, with
Existing single ball head structure is compared, and the amplitude increase that fan head is swung, expands wind-engaging scope, using effect is more preferable.
Brief description of the drawings
Fig. 1 is structure decomposition figure of the present utility model；
Fig. 2 is combining structure schematic diagram of the present utility model.
Embodiment
The utility model is elaborated below in conjunction with accompanying drawing and specific implementation.
As shown in Figure 1, 2, double universal turbofan of a kind of Band clamp of the present utility model, including fan head 1 and holder
2, the fan head 1 is connected by universal joint 3 with holder 2, and the universal joint 3 is a pair of ball head structure, has a body of rod 31, the body of rod
31 both ends are respectively provided with bulb 32,33, and two bulbs 32,33 are rotatably connected with fan head 1 and holder 2 respectively.The fan head 1
With the ball joint chair 11,21 with universal joint bulb 32,33 corresponding matchings, the middle part shape of the ball joint chair 11,21 are respectively equipped with holder 2
Into the open chamber 12,22 for accommodating bulb 32 of a top surface, two bulbs 32,33 of universal joint are respectively implanted two chamber 12,22
It is interior, fixed by fixing nut 4, two bulbs 32,33 are rotatably connected with ball joint chair 11,21 together with；
Several breach are circumferentially molded in the opening of the chamber 12,22, and is thus circumferentially formed and is used for holding tightly
The elastic arm 13,23 of bulb, the outside of ball joint chair 11,21 are provided with the external screw thread coordinated with fixing nut 4 in the lower section of elastic arm 13,23
14th, 24, fixing nut 4 can tighten up elastic arm 13,23 when consolidating with ball joint chair 11,21 spiral shells, make elastic arm 13,23 hold tightly in bulb 32,33
On, bulb 32,33 is also realized positioning after rotation with this.
Using said structure, the universal joint 3 that fan head 1 and holder 2 are connected due to the utility model uses double ball head structures,
Compared with existing single ball head structure, the amplitude that fan head is swung increases, and expands wind-engaging scope, and using effect is more preferable.
It is described above, preferred embodiment only of the present utility model, not it is used for limiting the utility model implementation
Scope.Therefore the change or modification done in every case according to claim of the present utility model and specification, it should all belong to the utility model
Within the scope of patent covers.
