Description
Technical field
The utility model relates to a kind of electric heating wire fastening piece, for vacuum packaging field.
Background technique
Electric heating wire fastening piece is fastening piece conventional on vacuum package machine sealer bar, existing fastening piece is mostly respectively to open a through hole at epoxy resin board two ends, between through hole and epoxy resin board two end part, have the passage passing for electric heating wire, clamping bolt for fastening electric heating wire is installed, as described in Figure 1 in passage; Clamping bolt is that common bolt is slotted at screw portion, as shown in Figure 2, when use, electric heating wire is through in the groove of clamping bolt, in the passage of electric heating wire from epoxy resin board, passes, and rotation clamping bolt is strained electric heating wire fix.This electric heating wire fastening piece is installed more loaded down with trivial details, and need to be by under clamping bolt integral demounting in the time of dismounting, uses and inconvenience.
Summary of the invention
The purpose of this utility model is to provide one and mounts and dismounts electric heating wire fastening piece easily.
For addressing the above problem, technical solution adopted in the utility model is:
A kind of electric heating wire fastening piece, comprise body, described body lower end has screw hole, housing pin is set in it, described body upper end has electric heating wire passage, described electric heating wire passage communicates with screw hole, and on described body, a side setting contrary with screw hole has the fixed support of through hole.Install when electric heating wire and only electric heating wire need be pierced into electric heating wire passage, rotatably compress screw, compress electric heating wire and can realize fastening to electric heating wire; While removing electric heating wire, rotatably compress screw, make it no longer compress electric heating wire, electric heating wire is pulled out from electric heating wire passage; The process of whole installation and removal only need rotatably compress screw, and need not dismantle other any parts, facilitates and saves time.
As further improvement of the utility model, described screw hole penetrates body.Through hole not only process for machining and manufacturing is simple, and facilitates for the manufacturing of electric heating wire passage.
As further improvement of the utility model, described fixed support and screw hole are all arranged on the lower end of body.When use, fixed support is arranged on epoxy resin board, and fixed support and screw hole are arranged on the lower end of body, makes electric heating wire fastening piece entirety stressed evenly.
As further improvement of the utility model, described body and fixed support are one-body molded.One-body molded guarantee electric heating wire fastening piece has enough intensity.
Further improve as of the present utility model, described bulk material is metal.The electric conductivity of metal is strong, and the wire that connects electric heating wire can directly be connected with fixed support, and need not be connected with electric heating wire.
In sum, the beneficial effects of the utility model are: easy installation and removal saves time, and simple in structure, low cost of manufacture, good economy performance.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Electric heating wire fastening piece as shown in Figures 3 to 6, comprise metal body 3-1 and fixed support 3-5, described body 3-1 lower end has screw hole 3-2, housing pin 3-3 is set in it, described body 3-1 upper end has electric heating wire passage 3-4, and described fixed support 3-5 and screw hole 3-2 are all arranged on the lower end of body 3-1, and described electric heating wire passage 3-4 communicates with screw hole 3-2, described fixed support 3-5 has two, has through hole on it.Body 3-1 described in the utility model and fixed support 3-5 are one-body molded.For ease of manufacturing, described screw hole 3-2 penetrates body.
The utility model electric heating wire fastening piece is arranged on the two ends of epoxy resin board 2, the two ends of epoxy resin board 2 respectively have a bolt hole, the end of epoxy resin board 2 is arranged between two fixed support 3-5, bolt hole on epoxy resin board 2 is relative with the through hole on fixed support 3-5, distance between two fixed support 3-5 is identical with the thickness of epoxy resin board 2, electric heating wire fixed block can be fixed on epoxy resin board 2 with a common fixing pin 5 through through hole and bolt hole.
Installing when electric heating wire 1, first electric heating wire 1 one end is placed in electric heating wire passage 3-4, and the end of electric heating wire 1 reaches the dead ahead of housing pin 3-3 or stretches into longlyer, tighten housing pin 3-3 and can fix; The other end of electric heating wire 1 passes the electric heating wire passage 3-4 of the electric heating wire fixed block that is positioned at epoxy resin board 2 the other ends, and strains electric heating wire 1, tightens housing pin 3-3.
Dismounting electric heating wire 1, only need turn housing pin 3-3, makes it no longer compress electric heating wire 1, then extracts electric heating wire 1 out.
In the utility model, screw hole 3-2 can penetrate body 3-1 and also can not wear the body 3-1 that breaks even, as long as electric heating wire passage 3-4 can be communicated with screw hole 3-2 innermost end.The utility model preferentially adopts screw hole 3-2 to penetrate the embodiment of body 3-1, and housing pin 3-3 is pressed on electric heating wire 1 on epoxy resin board 2 like this.
The arbitrary position that provides the wire of electric energy can be connected to electric heating wire fastening piece for electric heating wire 1 in the utility model, the present embodiment is preferably connected wire with the bolt of fixing electric heating wire fastening piece.
The utility model electric heating wire fastening piece is close on the two ends that are arranged on epoxy resin board 2, being different from existing electric heating wire fastening piece need to oblique notch on epoxy resin board 2, the structure of epoxy resin board 2 is affected, the utility model has overcome this drawback, has therefore extended the working life of epoxy resin board 2; Also, during due to use the utility model electric heating wire fastening piece, it is close on the two ends that are arranged on epoxy resin board 2, and the excellent heat conductivity performance of metal material, electric heating wire 1 two ends is difficult for aging, has increased the working life of electric heating wire 1.
The part of not doing to specify in all specification is prior art, or both can realize by prior art, and described in the utility model, concrete case study on implementation is only better case study on implementation of the present utility model, is not used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modify, all should serve as technology category of the present utility model.
