Though electronic machine oil level sensor solve monitoring liquid level in real time, structural strength is poor, the appearance in the environment of fluid thrill
Easy fracture, what electronic liquid level sensing device was utilized is that resistance wire tightens heating power measurement liquid level, internal under high and low temperature environment
Support around resistance wire expands with heat and contract with cold, and can cause resistance wire after resistance wire extension fracture, stent collapses taut not tight after stent expansion,
Resistance wire is contacted with support, product failure.
Utility model content
In view of the shortcomings of the prior art, the utility model discloses a kind of automobile engine oil liquid level sensor structure.
The technical solution of the utility model is as follows：
A kind of automobile engine oil liquid level sensor structure, including sleeve pipe, plug and it is fixed on described sleeve pipe and the plug
Outside, the shell that described sleeve pipe and the plug are connected together；Circuit printing plate is installed within the plug；It is described
Support is fixed with sleeve pipe；Wire is fixed with the support；Described wire one end be connected to the circuit printing plate it
On, the other end is connected with resistance wire；The resistance wire is wound on the support.
Its further technical scheme is that the support includes two sections, and the resistance wire is wound in the first of the support
Section；Also include snakelike elater；The second segment of the support, the other end and the resistance wire are fixed in one end of the snakelike elater
End be connected.
Its further technical scheme is to suppress fluted on described sleeve pipe, and described sleeve pipe is mutually solid with the support
It is fixed.
Its further technical scheme is that the groove is hex surface groove or slot rolling.
Its further technical scheme is that connection is tensioned between described sleeve pipe and the shell.
Its further technical scheme is outside described sleeve pipe, in described sleeve pipe and the junction of the shell, to be suppressed with
Multigroup groove.
Its further technical scheme is that the edge of the plug is outer male structure；The edge of the shell is inside
Turnup structure；When the outer cover suit is in the plug, the edge of the shell is snapped onto outside the edge of the plug.
Its further technical scheme is that described sleeve pipe is made up of aluminum alloy materials.
Advantageous Effects of the present utility model are：
The utility model provides a kind of simple in construction, intensity height, the high automobile engine oil liquid level sensor of reliability.
The utility model has a wide range of application, different engine models, and height of liquid level is different, but set of the present utility model
Length of tube can be lengthened or shortened therewith, and internal stent, assembly technology are constant, and product can apply to the most of type of client, full
The growth requirement of sufficient small lot polytypic.
The utility model is by redesigning internal structure, relative to prior art, and socket more firmly, and is to be used for high temperature
The various environment of low temperature and be hardly damaged, measurement accuracy is high.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram for being tensioned groove.
Fig. 3 is the schematic diagram of support and snakelike elater.
Embodiment
Fig. 1 is schematic diagram of the present utility model.As shown in figure 1, the utility model includes sleeve pipe 1, plug 6 and is fixed on
Outside sleeve pipe 1 and plug 6, the shell 2 that sleeve pipe 1 and plug 6 are connected together.
Sleeve pipe 1 abandons the plastic material of in the market, and selection light aluminum alloy material is made, and sleeve pipe 1 passes through tensioning with shell 2
Connection, technique simple strength is high, and aluminium alloy will not shake disconnected under vibration environment as plastic bushing.Fig. 2 is to be tensioned showing for groove
It is intended to.As shown in Fig. 2 in the junction 7 of sleeve pipe 1 and shell 2, being suppressed with multigroup groove structure, be conducive to further tensioning.It is recessed
Groove can be hex surface groove or slot rolling.
The edge of plug 6 is outer male structure；The edge 8 of shell 2 is inside turnup structure；When shell 2 is set in plug 6
When, the edge 8 of shell 2 is snapped onto outside the edge of plug 6, is fixed.
Circuit printing plate 5 is installed, electric signal for handling sensing etc. within plug 6.Support is fixed with sleeve pipe 1
11, wire 4 is fixed with support 11, and the one end of wire 4 is connected on circuit printing plate 5, and the other end is connected with resistance wire 3.
Resistance wire 3 is wound on support 11.
Suppress fluted on sleeve pipe 1, sleeve pipe 1 is mutually fixed with support 11.
Fig. 3 is the schematic diagram of support and snakelike elater.Fig. 3 shows a kind of preferred scheme, that is, has installed snakelike elater 10 additional.
As shown in figure 3, support 11 includes two sections, resistance wire 3 is wound in the first paragraph of support 11；Also include snakelike elater 10；Snakelike bullet
The second segment of support 11 is fixed in one end of silk 10, and the other end is connected with the end of resistance wire 3.
In the prior art, support 11 is that plastics are made into integration, resistance wire 3 be directly wound on support 11 that plastics are made it
On, under high and low temperature environment, plastics can expand with heat and contract with cold generation deformation, otherwise resistance wire 3 is pulled off, otherwise it is taut not tight.Shown in Fig. 3
