Description

The easy-to-mount rotary preceding cover of one kind and fan

Technical field

The utility model relates to family's electro-technical fields, more specifically to a kind of easy-to-mount rotary preceding cover And fan.

Background technique

In daily family life, we can encounter such situation unavoidably, when fan after a period of use, fan Surface and it is internal have many dusts, in the beautiful consideration with health, we can be removed and be cleaned.

The structure of fan group frame currently on the market is usually all that two fan guards are fixed by a plastic ring, such Although structure is convenient when disassembly, when installing, but needs two people to come sometimes while installing, so very Labor intensive.That is, it needs to which a people helps, another person is caught in cover in plastic ring, but in order to guarantee that cover is not fallen off, The size of plastic ring and cover size difference are relatively small, lead to that cover is difficult to be caught in circle.Therefore, it is necessary to current cover Body structure is improved to solve the problems, such as this.

By retrieval, also there is detaching structure in the structure of existing fan, such as Chinese Patent Application No. CN201720310552.1, the applying date: 2017.3.27, this application discloses a kind of combination fans, comprising: fan head, machine Head, pedestal column and pedestal, wherein the front end of the head and fan head are detachably connected, the lower end and bottom of the head The upper end of seat pillar is detachably connected, and the lower end of the pedestal column and the pedestal are detachably connected.

Although above scheme solves the problems, such as that fan installation is inconvenient, but without solving fan leaf cover portion point installation not Just, still labor intensive.

By retrieval, the structure of cleaning function, such as Chinese Patent Application No. can be provided by also having in the structure of existing fan CN201521106255.2, the applying date: 2015.12.26, the patent provides following technical solutions: a kind of work convenient for cleaning Industry fan, including fan guard, are equipped with flabellum in fan guard, and fan guard is equipped with the motor of driving flabellum rotation on one side, under fan guard Portion is equipped with the support frame for being used to support fan guard, and the fan guard includes front shroud, side cover and back cover, and front shroud includes upper front shroud under Front shroud, upper front shroud and lower front shroud are hinged, and upper front shroud can be relative to the downward front shroud direction overturning of hinge joint.With the above arrangement, clear The flabellum on fan top can be made to expose, hand can be directly protruding into wind by upper front shroud around hinge joint front shroud direction overturning downward when washing Fan cleaning inside flabellum.

Although above scheme solves the cleaning problems of Industrial fan, but exist between daily domestic fan and Industrial fan Difference, the cleaning problems of daily domestic fan are still urgently to be resolved.

Embodiment

With reference to the accompanying drawing, the utility model is further described

Referring to shown in Fig. 1 to Fig. 4, the easy-to-mount rotary preceding cover of one kind of the present embodiment, it includes fan cover Central cover 3, lattice framing 4, pressing plate 6 and support ring 7；4 one end of lattice framing is connect with 3 ball-joint of central cover, can be along week To swing.4 other end of lattice framing is provided with bulb 401, and bulb 401 is matched with card slot 702, and passes through pressing plate 6 and support ring 7 Connection is fixed bulb 401.

Specifically, 7 it is provided with card slot 702 in support ring, which is the single trough body structure being arranged at equal intervals, non- Annular.Each card slot is matched with a bulb 401, for fixing lattice framing.Further, for operating easily, in support ring Slideway 701 is provided on 7, card slot 702 is located in slideway 701.Slideway 701 is the annular groove along a circle inside support ring, card Slot 702 can be arc, have a diameter larger than the diameter of bulb 401, and the width of slideway 701 is not less than the diameter of bulb 401, so as to Bulb 401 can either slide in slideway 701, and can cooperate with card slot and fix.

In conjunction with Fig. 2, cambered way 601 is arranged on pressing plate 6, and cambered way 601 is the arc along a circle inside support ring The contact surface of connected in star, above-mentioned slideway 701 and card slot 702 is all smooth contact surface；Pressing plate 6 and support ring pass through screw 5 Connection is fixed bulb 401.

In conjunction with Fig. 3, the present embodiment central cover 3 is located among cover face, and central cover 3 inside front shroud body one Side can decide whether to be provided with recess as needed；4 one end of lattice framing and central cover 3 are articulated and connected, can be according to specific raw Production process is hinged using ball-joint structure, or use axis to decide whether, is mainly that by the swing of lattice framing 4 or turns It is dynamic.

The material of bulb 401 is abrasion-resistant material, and the surface being in contact with cambered way 601, slideway 701, card slot 702 For smooth surface；Screw 5 is mainly used for connecting pressing plate 6 and support ring 7, has certain length, guarantees to be released when pressing plate 6 Can make bulb 401 slide apart from when, screw 5 will not fall off, and pressing plate still can connect pressing plate 6 and support ring 7 simultaneously, keep away Exempt from erroneous for installation.Screw 5 can be disposed at equal intervals.

In conjunction with Fig. 1 and Fig. 4, a kind of fan of this implementation is allowed to and rear cover body 8, fan using above-mentioned preceding cover structure Leaf, support rod 2, support base 1, which are connected, forms fan entirety, and 2 lower end connecting support seat 1 of support rod, the upper end is connected with motor, Rear cover body 8 is sleeved on motor cabinet, and motor shaft passes through rear cover body 8 and connect with flabellum, and flabellum is covered with preceding cover 3.Due to Its structure prior art is more mature, is not repeating.

As an implementation, the shape of lattice framing 4 can be curve form, i.e., central cover 3 is with support ring 7 not same On one vertical plane, but the spacing of the card slot of fixed lattice framing 4 will meet safe design, avoid manpower from protruding into, damage；Afterwards Cover 8 and the structure of preceding cover are essentially identical, on the basis of original, replace central cover 3 with cyclic structure, convenient for transmission The installation of axis, in addition to this, the groove that 8 back side spaced set of rear cover body has protrusion to provide above part with power are formed Buckle structure, convenient for fixing.

The control switch 0 of fan is provided on the fan support seat 1 of the present embodiment, control switch 0 is generally knob and opens It closes or to adjust the state of fan, such as adjusts wind-force size by changing the state of control switch 0 for touch panel switch 0 It is more conventional in the prior art Deng, the technology, it repeats no more.The power of threaded hole and fan is provided on the support base 1 of fan Beneath portions are provided and are provided with threaded hole, support rod both ends are provided with the screw thread to match with threaded hole, pass through screw thread and screw thread Hole is sequentially connected, and makes a complete support section.

In use, at this time only needing when user has found that fan needs to clean by the fixation spiral shell on preceding cover Nail 5 unclamps certain length, the lattice framing 4 can be slided in slideway, such lattice framing 4 can be slided into side, to have Dust on enough space cleaning flabellums, and lattice framing 4 can be cleaned one by one.After cleaning, pico- pre-loading screw, Then in the bulb to corresponding card slot for sliding lattice framing 4, then screw 5 is tightened, completes installation.

Schematically the utility model and embodiments thereof are described above, description is not limiting, attached drawing Shown in be also one of the embodiments of the present invention, actual structure is not limited to this.So if this field Those of ordinary skill enlightened by it, without deviating from the purpose of the present invention, not inventively design Frame mode similar with the technical solution and embodiment, all should belong to the protection range of the utility model.
