Abstract
The utility model relates to a pump handle which comprises a metal handle body and a plastic part wrapped outside the handle body. The utility model is characterized in that the handle body comprises two separate connecting legs and a cross beam part, wherein, the cross beam part is provided with two end parts with curved parts, the two connecting legs are connected with the two end parts of the cross beam part, the connecting legs and the cross beam part adopt various materials, the surface request of the cross beam part is lower than the surface request of the connecting legs, the plastic part is used to wrap the connecting position between the connecting legs and the cross beam part. During the curving forming process, the curved position becomes short, to enable the stress to be released, the part distortion error becomes less, and because during the manufacture process, according to the various surface requests of the connecting legs and the cross beam part, different materials and different processing technologies are adopted on the connecting legs and the cross beam part, thereby the manufacture cost and the processing difficulty are reduced.
Description
Technical field
The utility model relates to a kind of auxiliary of pump, particularly relates to a kind of handle of pump.
Background technique
Water pump common on the market generally all includes component such as handle, shell, base, motor and impeller, traditional water pump handle is installed in the cover top portion of pump, mainly when moving or carry, conveniently mention water pump, consider the installation matching relationship between handle and the water pump, distance between two installation feet of handle need satisfy certain precision, and clubfoot is installed is had certain surface Machining requirement for two of handle, to improve corrosion resistant performance, generally, handle is to adopt stainless steel to make, and is coated with working of plastics in the intermediate portion.
Traditional handle adopts the stainless steel integral piece curved molded more, yet often there are some defectives in the processing technology of a bending forming of materials such as stainless steel, because bending forming of material can produce anamorphic effect at bending part because of stress relief, when the bending pin is long, the accessory size error that this distortion brings can become bigger, thereby be difficult to guarantee to bend the distance between two clubfoots of back handle, can have influence on the installation of handle on water pump, even can't install.In addition, in order to increase frictional force, Security in use and to improve feel, can be sealed with plastic wrapper at stainless steel profiled member hand-holding part again, because the handle at plastic wrapper place is a supporting effect, do not need too high processing request in fact, if adopt with the integral piece that the clubfoot same material is installed, also can increase processing cost and difficulty.
The model utility content
Technical problem to be solved in the utility model is the handle that a kind of more economical and practical pump is provided at above-mentioned prior art present situation, it can effectively reduce the assembly error that the metallic material of handle causes because of machining deformation, and cost of material is reduced.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of handle of pump, include metal handle body and the working of plastics that is coated on the handle body outside, it is characterized in that described handle body includes two and independently connects leg and a cross-member, described cross-member has the end of two band kinks, described two connect legs and link together with two ends of cross-member respectively, described connection leg adopts different materials with cross-member, and the surface requirements of cross-member is lower than the surface requirements that connects leg, and working of plastics will encase the connection part that connects leg and cross-member.
Connection between described connection leg and the cross-member can be adopted various fixedly connected mode of the prior art, can adopt the Placement of drive fit structure, also to adopt bonding mode, can also adopt welding manner will connect leg and rigidly fix with cross-member and be in the same place.
Useful is, the end of described cross-member kink has hangers, accordingly, then have hanging hole on the described connection leg with the suitable opening of described hangers profile, hanging hole with will be connected leg after hangers closely cooperates and the cross-member drive fit links together, simple and practical, connect leg in the time of can preventing the handle of portable pump effectively and break away from cross-member, be connected firmly.
Useful is, the end of described cross-member kink has the hanging hole of opening, accordingly, then have on the described connection leg and the suitable hangers of described hanging hole profile, hanging hole with will be connected leg after hangers closely cooperates and the cross-member drive fit links together, simple and practical, connect leg in the time of can preventing the handle of portable pump effectively and break away from cross-member, be connected firmly.
Compared with prior art, advantage of the present utility model is: the handle of the curved molded pump of original integral piece is divided into cross-member and is connected leg come independence processing respectively, thus, the part deformation error that makes stress discharge and produce reduces because bending part shortens in the bending forming course of working, thereby guaranteed the installation dimension precision of integral handle part, again because in manufacture process, according to the different surfaces requirement that connects leg and cross-member, adopt different materials and different processing technologys to connecting leg respectively with cross-member, thereby reduced manufacture cost and difficulty of processing.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Shown in Fig. 1～3, the handle of this kind pump, include one and independently connect leg 1 by two respectively, 2 and handle bodies that cross-member 3 is formed, described cross-member has two band kinks 33,34 end, connect leg 1 for allowing, 2 are fixed firmly on the cross-member 3, have integral body on each end of described cross-member and be the hangers 31 of " protruding " type, 32, described connection leg 1, then have on 2 and the suitable opening hanging hole 11 of described hangers profile, 21, this opening hanging hole 11,21 with hangers 31,32 will connect leg 1 after closely cooperating, 2 and cross-member 3 drive fits connect as one.
Described handle body also is nested with one and has the working of plastics 4 of same kink 41,42 with described cross-member, working of plastics 4 will encase the connection part that connects leg 1,2 and cross-member 3, strengthened the frictional force of handle body, and improved the feel of hand when gripping handle body, improve to use and go up Security.Described connection leg adopts different metallic material with cross-member, generally connects leg and adopts the stainless steel material of having relatively high expectations, and cross-member then adopts ordinary metallic material to get final product, thereby has reduced cost of material.
In like manner, have the opening hanging hole that is " protruding " type on each end of cross-member, described connection leg then has and the suitable hangers of described hanging hole profile, this opening hanging hole with will be connected leg after hangers closely cooperates and the cross-member drive fit connects as one.
Above-mentioned cross-member can adopt various fixed connection method of the prior art with the fixedly connected mode that is connected leg, except described with hangers and the mutual close-fitting Placement of hanging hole, directly will connect the mode that leg and cross-member be welded to each other and rigidly fix together as adopting, perhaps adopt bonding mode to connect leg and cross-member is fixed together, omit accompanying drawing at this, repeat no more.
