Description
Technical field
The utility model is related to plastic hot melt field, more particularly to a kind of hot melt head.
Background technology
With the development of science and technology, 90% handset shell on the market is that hot melt is assembled by full-automatic fuse machine at present
The structure of hot melt head on nut, traditional fuse machine as shown in figure 1, but be due to housing side space than relatively limited, this
The hot melt head for planting structure easily scalds housing side, and then causes the Assembly Interference of housing, in addition, the hot melt head of said structure is done
Excessive glue occurs for the nut surface of the hot-melting nut gone out and face is uneven, such that the pulling capacity of nut, torsion reliability are reduced,
So as to cause the fixing intensity of housing to reduce.
The problem of being in summary our current urgent need to resolve there is provided a kind of new-type heat-melting head.
Utility model content
The purpose of this utility model is to provide a kind of hot melt head, protects the side of housing, improves the drawing of nut
Power, the reliability of torsion, so as to realize the purpose for improving housing fixing intensity.
In order to solve the above technical problems, embodiment of the present utility model provides a kind of hot melt head, the hot melt head is used for
The hot-melting nut on plastic casing；Include heat-transfer pipe and tempreature bulb；Heat-transfer pipe is connected with tempreature bulb；Wherein, heat-transfer pipe and hot melt
Pipe is coaxially disposed, and heat-transfer pipe is identical with the internal diameter of tempreature bulb, and the external diameter of heat-transfer pipe is more than the external diameter of tempreature bulb.
The utility model embodiment in terms of existing technologies, by reducing the external diameter of tempreature bulb on hot melt head, makes
The side for obtaining housing is protected, and improves pulling capacity, the reliability of torsion of nut, so as to realize raising housing fixing intensity
Purpose.
In addition, heat-transfer pipe is integrally formed with tempreature bulb, such heat-transfer pipe can be produced with tempreature bulb by same mould, section
About making material.
In addition, heat-transfer pipe, tempreature bulb are hollow cylinder.
In addition, the wall thickness of tempreature bulb is 0.25mm.
In addition, the height of tempreature bulb is 6mm.
In addition, tempreature bulb is copper pipe.
In addition, being provided with screw thread on the outer wall of tempreature bulb.
In addition, the lid for being provided for being connected with external heat source around the end of heat-transfer pipe.

Fig. 2 is the stereogram of the hot melt head in the utility model first embodiment；
Fig. 3 is the profile of the hot melt head in the utility model first embodiment.
Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Each embodiment of type is explained in detail.However, it will be understood by those skilled in the art that each in the utility model
In embodiment, in order that reader more fully understands the application and proposes many ins and outs.But, even if without these skills
Art details and many variations based on following embodiment and modification, can also realize the application technical side claimed
Case.
First embodiment of the present utility model is related to a kind of hot melt head, for the hot-melting nut on plastic casing；Such as Fig. 1
Shown in~2, the hot melt head includes heat-transfer pipe 1 and tempreature bulb 2；Heat-transfer pipe 1 is connected with tempreature bulb 2；Wherein, heat-transfer pipe 1 and hot melt
Pipe 2 is coaxially disposed, and heat-transfer pipe 1 is identical with the internal diameter of tempreature bulb 2, and the external diameter of heat-transfer pipe 1 is more than the external diameter of tempreature bulb 2.
During hot melt head is actually prepared, to allow heat-transfer pipe 1 to be produced with tempreature bulb 2 by same mould, section
About making material, in the present embodiment, heat-transfer pipe 1 can be integrally formed with tempreature bulb 2, certainly, heat-transfer pipe 1 and tempreature bulb 2
It can also be connected by modes such as welding, present embodiment should not be as limit.
Specifically, in the present embodiment, heat-transfer pipe 1, tempreature bulb 2 can be hollow cylinders, so by heating head
The nut bore for heating out on housing is manhole.Certainly, heat-transfer pipe 1, tempreature bulb 2 can also be other shapes, this
Heat-transfer pipe 1, tempreature bulb 2 can be selected according to the shape of nut bore is made in housing, present embodiment is not repeated one by one herein.
Further, in the present embodiment, it is 0.25mm that the wall thickness of tempreature bulb 2, which can be set,；The height of tempreature bulb 2 can
It is 6mm to set.It is worth noting that, those skilled in the art can set wall thickness, the height of tempreature bulb 2 as needed,
Present embodiment should not be as limitation.
It is worth noting that, in the present embodiment, tempreature bulb 2 can be copper pipe.Certainly, tempreature bulb 2 can also be it
His metal tube, those skilled in the art can flexibly select the material of tempreature bulb 2 as needed, and present embodiment should not be as
Limitation.
In addition, in the present embodiment, the lid 3 for being provided for being connected with external heat source around the end of heat-transfer pipe 1.This
Sample fuse machine operationally acts on hot melt head in the metal nuts for treating melting welding, delivers heat to housing again by metal nuts, makes
Housing is obtained to melt and fuse together with metal nuts.So as to complete the hot-melting nut on housing.
Compared with prior art, in present embodiment, by the external diameter for reducing tempreature bulb on hot melt head so that the side of housing
Face is protected, and improves pulling capacity, the reliability of torsion of nut, so as to realize the purpose for improving housing fixing intensity.
Second embodiment of the present utility model is related to a kind of hot melt head.Second embodiment is that first embodiment is changed
Enter, mainly the improvement is that：Screw thread is provided with the outer wall of tempreature bulb.Hot melt head can so be improved and the metal of melting welding is treated
Frictional force between nut, it is to avoid heat transfer is uneven caused by the loose contact of hot melt head and metal nuts.
The those of ordinary skill in this domain is appreciated that the respective embodiments described above are to realize specific implementation of the present utility model
Example, and in actual applications, can to it, various changes can be made in the form and details, without departing from spirit of the present utility model
And scope.
