Abstract
A box-type fan includes a fan frame body and a motor and is characterized in that the fan also includes a connection structure connecting the fan frame body and the motor, the connection structure includes an upper connecting plate and a low connecting plate, the upper connecting plate and the low connecting plate are fixed on the motor respectively, the motor is connected on the fan frame body through the upper and the low connecting plate. The connection structure is added in the novel fan of the utility model to insulating isolate the motor and the fan frame body to increase the safe parameter, guarantees the stable connection between the two parts at the same time, and save the cost by improving the fan's material. For example, the front end cover and the back end cover of the motor are made of cold-rolled steel sheet so as to save the cost of the end covers; the upper and the low connecting plates are made of plastics so as to not only guarantee the reliability of the connection but also save the product cost. In addition, a rotary switch and a knob can be arranged on the upper connecting plate to make the fan's structure more compatible. Thereby, the utility model has advantages of safety and reliability, good insulation performance, high produce efficiency and low cost.
Description
Technical field
The utility model relates to a kind of frame fan.
Background technique
For common fan, motor and the direct fixed connecting means of general employing of being connected of fan frame body, though its secure and reliable connection, owing to be directly fixing, motor and metal framework are conductings, and security of products is decreased.
In addition, electric motor end cap is generally by the cast aluminium manufacturing, and cast aluminium end cap relative cost is higher, and product is lacked competitiveness in market.
The model utility content
The purpose of this utility model provides a kind of frame fan, is used for fan frame body and motor connection structure connecting by what this fan was set up, and motor and fan frame body insulation are isolated, increase safety coefficient, simultaneously guarantee that again both firmly connect, and the improvement by used material, the saving cost.
A kind of frame fan provided by the utility model, comprise fan frame body and motor, it is characterized in that: it also comprises the linkage structure that is used to connect fan frame body and motor, this linkage structure comprises upper junction plate and lower connecting plate, described upper junction plate, lower connecting plate are separately fixed on the described fan electromotor, and described motor is connected on the fan frame body by upper and lower connecting plate.
In above-mentioned frame fan, fan frame body is a center.
In above-mentioned frame fan, also comprise the rotary switch and the knob that are installed on the upper junction plate.
In above-mentioned frame fan, power line socket or power line button bit are installed on described lower connecting plate.
In above-mentioned frame fan, the startup capacitor is installed on the lower connecting plate.
In above-mentioned frame fan, comprise front cover and rear end cover, this forward and backward end cap is made by Cold Rolled Sheet Steel.
In above-mentioned frame fan, upper junction plate and lower connecting plate all adopt plastic production to form.
Owing to adopted above-mentioned technical solution, in the utility model fan, set up linkage structure, motor and fan frame body insulation are isolated, increase safety coefficient, simultaneously guarantee that again both firmly connect, and the improvement by the fan material, save cost, for example: the front cover of motor and rear end cover adopt Cold Rolled Sheet Steel to make, saved the cost of end cap, upper and lower connecting plate adopts plastic production, has both guaranteed firm and reliable connection, has reduced product cost again.In addition, on upper junction plate, rotary switch can be installed and knob makes the fan structure compactness.Therefore the utlity model has safe and reliable, good insulation preformance, manufacturing efficiency height, low cost and other advantages.
Description of drawings
By the description of a following embodiment to a kind of frame fan of the utility model, can further understand purpose of the present invention, specific structural features and advantage in conjunction with its accompanying drawing.Wherein, accompanying drawing is:
Fig. 1 is a kind of embodiment's of the utility model frame fan a three-dimensional exploded view;
Fig. 2 is one of another kind of embodiment's of the utility model frame fan a three-dimensional exploded view.
In the accompanying drawings, the numbering among the figure is represented as respectively:
1: rotary switch
2: center
3: upper junction plate
4: capacitor
5: rear end cover
6: rotor assembly
7: stator module
8: front cover
9: knob
10: lower connecting plate
Embodiment
The utility model frame fan, its linkage structure have two kinds of forms, and a kind of is belt switch (referring to Fig. 1) not on the connecting plate, and another kind is that rotary switch (referring to Fig. 2) is installed on the connecting plate, makes fan structure compacter.
As shown in Figure 1, the utility model frame fan comprises fan center 2, motor and is used to be connected the linkage structure of fan center 2 and motor.
Motor comprises stator module 7, rotor assembly 6, rear end cover 5, front cover 8.
This linkage structure comprises upper junction plate 3 and lower connecting plate 10.
Upper and lower connecting plate 3,10 can make motor and fan center 2 isolate, and makes fan drum that the double insulation protection arranged.
Referring to Fig. 2, the frame fan can also comprise rotary switch 1 and the knob 9 that is installed on the upper junction plate 3.Make the fan structure compactness, also other part and assembly can be installed as required in the reality certainly.
(as: motor, center, last lower connecting plate etc.) adopt screw to connect between each parts of the present utility model, also can adopt other similar linkage structure form in the reality certainly.
Power line socket or fixed power source cableties position can be installed on the lower connecting plate 10.
The front cover and the rear end cover of motor are made by Cold Rolled Sheet Steel.
In sum, the utility model frame fan has been set up linkage structure in its structure, this linkage structure is used to connect frame fan center (generally making with metal) and fan electromotor, mainly connect fan frame body and fan electromotor by two plastics connecting plates, make it than the direct mode of fixedlying connected between traditional motor and fan frame body, this structure not only can realize motor and fan frame body firmly is connected but also makes simple efficient height.And make motor and framework that double insulation arranged.Connecting plate adopts plastic production, has not only guaranteed join strength but also reduced cost, also has the damping noise reduction effect, makes fan have stationarity preferably.
Therefore, the utility model is simple and reliable for structure, makes easy to assemblyly, improves the safety coefficient of product, can reduce the director costs of fan by a relatively large margin, and can make multiple variation as required, so that product is on a good wicket in competition.
Though the utility model frame fan is described with reference to current instantiation, but those skilled in the art should be realized that, above example only is to be used for illustrating the utility model, also can make the variation and the modification of various equivalences under the situation that does not break away from the utility model spirit.Therefore, if in connotation scope of the present utility model to the variation of above-mentioned example, modification all will drop in the scope of claims of the present utility model.
