Yet, structure with the float-type liquid level sensor among above-mentioned each liquid level sensor is the simplest, as shown in Figure 1, package assembly for existing liquid level sensor, include holder 10 ', electron tube 20 ' and end cap 30 ', this electron tube 20 ' be used to entangle floating drum is equipped with various elements in it.This its assembling process of existing liquid level sensor is very simple, at first with electron tube 20 ' the upper end insert holder 10 ' mounting hole 11 ' in, then, by welding manner make holder 10 ' the lower surface be sealed and matched and be connected with this electron tube 20 ' formation, this electron tube 20 ' also is with this and this holder 10 ' be connected and fixed, then with end cap 30 ' with this holder 10 ' be screwed together fixing and with holder 10 ' upper end open cover.
Above-mentioned existing liquid level sensor package assembly, though can offer the effect that the user is connected and fixed electron tube and mount pad, simple in structure, really has progressive, but when using, reality but finds still to have many deficiencies on himself structure and the usability, cause existing liquid level sensor package assembly in practical application, fail to reach best result of use and task performance, now its shortcoming is summarized as follows: it is insecure that above-mentioned electron tube is depended merely on mode and this holder strength of joint of welding, vibration along with electron tube, this weld is easy to lose efficacy, thereby cause electron tube and this holder poor sealing, influence the operate as normal of liquid level sensor, even can cause electron tube to come off separating, thereby cause the thorough damage of liquid level sensor to re-use with this holder.
The utility model content
In view of this, the utility model is at the disappearance of prior art existence, and its fundamental purpose provides a kind of liquid level sensor package assembly, and it can effectively solve existing liquid level sensor package assembly and connect unstable phenomenon, improves the reliability that sensor uses.
For achieving the above object, the utility model adopts following technical scheme:
A kind of liquid level sensor package assembly includes holder, electron tube and end cap; This holder is provided with a mounting hole, the upper end of this electron tube is set in this mounting hole, this end cap covers the upper end open of this mounting hole, the radially recessed draw-in groove that is formed with of the internal face of this mounting hole, to wall that should electron tube radially evagination be formed with screens, this screens closely is installed in this draw-in groove.
As a kind of preferred version, the upper surface of described electron tube and the inner bottom surface of end cap are inconsistent, and the upper surface of this electron tube and this holder form the sealing and fixing structure by welding.
As a kind of preferred version, described holder and electron tube are metal material.
The utility model compared with prior art has tangible advantage and beneficial effect, particularly, and as shown from the above technical solution:
One, by the radially recessed draw-in groove that is provided with on the internal face of mounting hole, and utilize on this electron tube the radially screens of evagination and this draw-in groove closely to clamp, the mode that has replaced with welding installs, its assembling is more convenient, and make this electron tube can not separate because of vibration comes off with this holder, strength of joint strengthens greatly, thereby has improved the reliability that product uses.
Two, the mode by welding is with the upper surface of this electron tube and this holder formation sealing and fixing structure, make the sealing and fixing intensity of this electron tube and this holder further strengthen, effectively guarantee the bulk strength of product, in the time of particularly will vibrating the damage of electron tube is dropped to minimumly, can therefore not damage to guarantee product.
For more clearly setting forth architectural feature of the present utility model and effect, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment:
