Description

A kind of compact lowering or hoisting gear

Technical field

The utility model is related to Motor drive field, especially relevant with a kind of compact lowering or hoisting gear.

Background technology

Motor driver utilization rate on household electrical appliance is very high, many kitchen appliances such as lampblack absorber, gas-cooker, integrated kitchen range In with quantity not wait small machine and supporting driving executing agency.

Executing agency is generally driven to be that lift is relatively common, it is also possible to referred to as telescopic, i.e. electric motor starting, by screw mandrel Circular motion is converted into into linear motion, the flexible reciprocating motion of some part is then driven.In this kind of lowering or hoisting gear, The installing space for retaining substantially is needed to include motor volume, screw mandrel plus the telescoping rod reciprocating stroke of Lift Part Length space.And now household electrical appliance style does not stop to update, the space requirement that motor is installed is more and more harsher, therefore volume Little lowering or hoisting gear increasingly has big potentiality market, and the present inventor designs the liter of a compact for the market demand Thus falling unit, this case produces.

Utility model content

The purpose of this utility model is to provide a kind of compact lowering or hoisting gear, and simple structure design, length reduces half, greatly Amplitude reduces installation volume, has a good application prospect in household electrical appliances market.

For achieving the above object, the technical solution adopted in the utility model is as follows：

A kind of compact lowering or hoisting gear, including by motor-driven screw mandrel, the housing covered on outside screw mandrel, coordinate on screw mandrel Nut；Described housing belly offers fluting along screw mandrel axial direction, and nut sleeve is on screw mandrel, while stretching out from fluting As outside installation connecting seat.

Described is recessed on the line of symmetry of housing.

The notch both sides of the fluting are provided with fagging.

The part formation blocks that described nut is stretched out outside notch is fitted on fagging.

Described nut stretches out the part outside notch and offers the hole position being fixedly connected.

Described screw mandrel two ends are bearing in enclosure interior two ends by bearing.

Described screw mandrel is vertical with motor to be connected.

Described housing outer end is connected with fixing end.

It is of the present utility model to have the advantages that：

1st, in the utility model, eliminate in conventional procedure stretch the body of rod, directly slot on housing, nut directly from Stretch out in fluting as connecting seat, outside connector can be installed directly with nut, save the part of expansion link, while The stroke space of expansion link is not needed, just as the reciprocating stroke space for lifting, both close two and are for the length space of screw mandrel itself One, realize compact design.

2nd, the setting of fagging can improve the smoothness of nut movement.

3rd, motor and the vertical connection of screw mandrel can also shorten the length of whole product.

Description of the drawings

Fig. 1 is the generalized section one of the utility model preferred embodiment；

Fig. 2 is A-A generalized sections in Fig. 1；

Fig. 3 is the structural representation of the utility model preferred embodiment.

Specific embodiment

Referring to Fig. 1 to Fig. 3, the utility model preferred embodiment is further elaborated.

A kind of compact lowering or hoisting gear, the part being mainly concerned with includes screw mandrel 1, housing 2, nut 3, motor 4, fagging 5.

The outside of screw mandrel 1 is covered with housing 2, and the two ends of screw mandrel 1 are bearing in the inside at the two ends of housing 2 by bearing 6.The abdomen of housing 1 A fluting 7 is opened up in portion, fluting 7 is axially in parallel with screw mandrel 1.The position of fluting 1 is generally the symmetric position of surface of shell. The spiral of nut 3 on screw mandrel, the moving member being mounted on screw mandrel 1, at the same the outer end of nut 3 stretch out fluting 7 outside, extension Divide and form block, some hole positions 8 have been opened up thereon, fix for the installation with joint outer part.For nut 3 and external connection The movement of part is stablized, and in the notch both sides of fluting 7 one piece of fagging 5 is provided with, and it is steadily mobile that nut 3 is fitted in fagging 5.

In the present embodiment motor 4 and screw mandrel 1 be it is vertical be connected, so can in the longitudinal direction reduce space.Exist simultaneously Fixing end 9 is provided with the outer end of housing 1, facilitates of the present utility model installation to fix.

During utility model works, motor 4 starts drive screw 1 and rotates forward, and nut 3 is enclosed within screw mandrel 1, and by fluting 7 Restriction cannot rotate, can only be along the rectilinear movement of 7 cell body directions of fluting, screw mandrel 1 invert, then nut 3 is back moved.Realize Reciprocal elevating movement.The utility model screw mandrel length space can be used as the space of reciprocating stroke, and installation volume is greatly reduced.

More than one kind of the utility model preferred embodiment, make under the utility model concept thereof it is some its He is simple to replace and changes, and should all be considered as belonging to protection category of the present utility model.
