To solve problem of the prior art, the utility model provides a kind of not fragile when by all directions destructive power Broken mercury clinical thermometer.

In order to achieve the above object, the utility model uses following technical scheme：A kind of mercury clinical thermometer, including clinical thermometer Body, the clinical thermometer body portion appearance sealing are provided with heat-conducting plastic shell, heat-conducting plastic shell sealing cladding mercury bubble, clinical thermometer The first cushion is provided between body front end and heat-conducting plastic shell inner surface, the sealing of clinical thermometer rear body outer surface is provided with interior Shell, the second cushion is provided between clinical thermometer body rear end and inner casing inner surface, is set between inner casing lower surface and shell upper surface There is gap, the 3rd cushion is provided between inner casing rear end and outer casing back.

Mercury bubble front end on the clinical thermometer body is provided with solid glass post, solid glass column length and width and mercury Bubble end face length and width matches.

The shell is triangular prism shape.

The shell is with inner casing and heat-conducting plastic shell joint portion using sealed connection.

The utility model has the advantages that：

1）Practicality is high：Clinical thermometer is conveniently easy to family practice use, is hardly damaged；

2）It is safe：Even if interior clinical thermometer is broken, mercury pollutes around will not also sputtering, and makes mercury processing convenient；

3）Up time is grown；

4）Manufacturing cost is low；

5）The degree of accuracy is high.

Brief description of the drawings

Fig. 1 is the utility model cross section structure diagram.

Embodiment

The utility model is described in further details below by embodiment, embodiment is only used for illustrating that this practicality is new Type, it is not intended to limit the scope of the utility model.

A kind of mercury clinical thermometer as shown in Figure 1, including clinical thermometer body 5,5 wide 0.3cm of clinical thermometer body, straight tube structure Also existing mercurial thermometer can be directly used, the sealing of the forward outer surface of clinical thermometer body 5 is provided with heat-conducting plastic shell 4, heat conduction modeling The sealing cladding mercury of material shell 4 bubble 3, heat-conducting plastic shell 4 adds a certain amount of graphite using heat-conducting plastic, then its thermal conductivity factor can More than the thermal conductivity factor of glass, the accuracy of measurement is ensure that, graphite will not be sterilized agent corrosion, and heat-conducting plastic is resistant to chemical etching Outstanding ethanol, have some strength, impact strength, toughness, ageing-resistant, deformation behavior is small, the front end of clinical thermometer body 5 and heat-conducting plastic shell 4 The first cushion 1 is provided between inner surface, the pad of the first elasticity 1 uses butyl rubber, in clinical thermometer body 5 by external world power It is seamless to play a part of fixed buffering clinical thermometer body, the thickness 0.1-0.2cm of heat-conducting plastic shell 4, and clinical thermometer body 5 during effect Gap connects；The sealing of the external rear face of clinical thermometer body 5 is provided with inner casing 8, the thickness 0.08cm-0.15cm of inner casing 8, and clinical thermometer body 5 seamless connections；Inner casing 8 uses transparent plastic Rotating fields, and second is provided between the rear end of clinical thermometer body 5 and the inner surface of inner casing 8 Cushion 9, the second cushion 9 use butyl rubber, and fixed buffering is played by the external world masterpiece used time in clinical thermometer body 5 The effect of clinical thermometer body 5, gap 7 is provided between the lower surface of inner casing 8 and the upper surface of shell 6, when destructive power further increases, The effect of further buffer corruption power is played in gap 7, so as to protect mercury clinical thermometer not damaged, the rear end of inner casing 8 and the rear end of shell 6 it Between be provided with the 3rd cushion 10, cushioning effect is further functioned as when mercury clinical thermometer is by cross force can protect clinical thermometer sheet Body 5 is without damage, and the shell 6 is connected with inner casing 8 and the joint portion 11 of heat-conducting plastic shell 4 using hot-melting sealed or glue sealing, Or other connected modes that can play fine sealing function, the thickness 0.1cm-0.2cm of shell 6, shell 6 use modified polycarbonate （PC）Rotating fields, add antioxidant ultra-violet absorber if necessary；It is transparent（It is easy to reading）, high intensity, high impact, size Good security, it is anti-aging（Outstanding ultraviolet）, it is corrosion-resistant（Thimerosals such as medicinal alcohol etc.）Dimensional stability is good, when clinical thermometer by When being such as extruded to longitudinal destructive power, heat-conducting plastic shell and shell and inner casing play cushioning effect jointly can protect clinical thermometer sheet Body 5 is without damage, and when clinical thermometer is such as vertically dropped by horizontal destructive power, heat-conducting plastic shell 4 and shell 6 and inner casing 8 coordinate First cushion 1 and the second cushion 9, the 3rd cushion 10 play cushioning effect and protect clinical thermometer body 5 without damage jointly, When clinical thermometer is by oblique destructive power（Sideling fall）, inner casing 8 prevents clinical thermometer deformation from fractureing, on clinical thermometer body 5 Mercury steeps 3 front ends and is provided with solid glass post 2, and mercury steeps 3 long 1.5cm, solid glass post thickness 0.1-0.2cm, solid glass post Length and width matches with mercury bubble end face length and width, and it is all glass material that solid glass post 2 steeps 3 outer surfaces with mercury Matter, the setting of solid glass post 2 causes the first cushion 1 directly need not be contacted with mercury bubble 3, so as to ensure that enough heat conduction Area, shell 6 are triangular prism shape, are not easy to slide by the used time.

It is described above, only it is preferred embodiment of the present utility model, is not that other forms are made to the utility model Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent The equivalent embodiment of change.But it is every without departing from the content of the technical scheme of the utility model, it is real according to technology of the present utility model Any simple modification, equivalent variations and the remodeling that confrontation above example is made, still fall within the guarantor of technical solutions of the utility model Protect scope.
