Abstract
The utility model discloses a rubber head drip tube subassembly, include: rubber head drip tube and PVC sleeve, rubber head drip tube includes that glass pipe shaft and cover establish the gluey head of the head of glass pipe shaft, open -ended shape of PVC sleeve with the afterbody phase -match of glass pipe shaft, another opening of PVC sleeve is the tip, the plastic sheath pipe box is established the afterbody of glass pipe shaft. This kind of rubber head drip tube subassembly establishes the PVC sleeve through the afterbody cover of the glass pipe shaft at rubber head drip tube, can play the effect of the afterbody of protection glass pipe shaft, and another opening of PVC sleeve is the tip simultaneously, because the material of PVC sleeve is softer for glass to be convenient for inhale reagent at the bottom of the bottle. For traditional rubber head drip tube, this kind of rubber head drip tube subassembly uses comparatively conveniently.
Description
Technical field
This utility model is related to one brood lac dropper assembly.
Background technology
The pipe body part of traditional experiment glue head dropper is full glass, and pipe shaft is shorter, easily breaks up dropper during use
Ozzle, and be also not easy to be drawn onto bottom of bottle reagent when drawing reagent, use more inconvenient.
Utility model content
Based on this it is necessary to provide a kind of glue head dropper assembly easy to use.
One brood lac dropper assembly, including：Glue head dropper and plastic bushing；
Described glue head dropper includes glass pipe shaft and is set in the glue head of the head of described glass pipe shaft, described plastic sheath
The shape of one opening of pipe is matched with the afterbody of described glass pipe shaft, and another opening of described plastic bushing is tip,
Described plastic bushing is set in the afterbody of described glass pipe shaft.
In one embodiment, after described plastic bushing is set in the afterbody of described glass pipe shaft, described plastic bushing with
The described length of part of glass pipe shaft laminating and the ratio of the length of described glass pipe shaft are 1：2～3：4.
In one embodiment, the length of the part that described plastic bushing is fitted with described glass pipe shaft and described glass tubing
The ratio of the length of body is 2：3.
In one embodiment, after described plastic bushing is set in the afterbody of described glass pipe shaft, described plastic bushing with
The described length of part of glass pipe shaft laminating and the ratio of the length of described plastic bushing are 3：4～9：10.
In one embodiment, the length of the part that described plastic bushing is fitted with described glass pipe shaft and described plastic sheath
The ratio of the length of pipe is 4：5.
In one embodiment, a diameter of 1.5mm～3mm of the tip of described plastic bushing.
In one embodiment, a diameter of 2mm of the tip of described plastic bushing.
This brood lac head dropper assembly passes through the sheathed plastic bushing of afterbody of the glass pipe shaft in glue head dropper, can play guarantor
The effect of the afterbody of shield glass pipe shaft, another opening of plastic bushing is tip simultaneously, because the material of plastic bushing is relative
Softer in glass, consequently facilitating being drawn onto bottom of bottle reagent.With respect to traditional glue head dropper, this brood lac head dropper assembly uses
More convenient.
Brief description
Fig. 1 is the structural representation of the glue head dropper assembly of an embodiment.
Specific embodiment
Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with the accompanying drawings and tool
Body embodiment is described in detail to specific embodiment of the present utility model.Elaborate a lot specifically thin in the following description
Section is in order to fully understand this utility model.But this utility model can be come with being much different from alternate manner described here
Implement, those skilled in the art can do similar improvement without prejudice in the case of this utility model intension, and therefore this practicality is new
Type is not embodied as being limited by following public.
As shown in figure 1, the glue head dropper assembly of an embodiment is it is characterised in that include：Glue head dropper 10 and plastic sheath
Pipe 20.
The glue head 14 that glue head dropper 10 includes glass pipe shaft 12 and is set in the head of glass pipe shaft 12.
The shape of one opening 22 of plastic bushing 20 and the afterbody of glass pipe shaft 12 match, plastic bushing 20 another
Individual opening 24 is tip, and plastic bushing 20 is set in the afterbody of glass pipe shaft 12.
Preferably, plastic bushing 20 is soft plastic sleeve pipe.
After plastic bushing 20 is set in the afterbody of glass pipe shaft 12, plastic bushing 20 is fitted in glass pipe shaft 12 major part
Together.
Preferably, the ratio of the length of the length of the part that plastic bushing 20 is fitted with glass pipe shaft 12 and glass pipe shaft 12
For 1：2～3：4.
Particularly preferred, the length of the length of the part that plastic bushing 20 is fitted with glass pipe shaft 12 and glass pipe shaft 12
Ratio is 2：3.
Preferably, the ratio of the length of the length of the part that plastic bushing 20 is fitted with glass pipe shaft 12 and plastic bushing 20
For 3：4～9：10.
Particularly preferred, the length of the length of the part that plastic bushing 20 is fitted with glass pipe shaft 12 and plastic bushing 20
Ratio is 4：5.
Preferably, a diameter of 1.5mm～3mm of the tip of plastic bushing 20.
Particularly preferred, a diameter of 1.5mm～3mm of the tip of plastic bushing 20.
This brood lac head dropper assembly passes through the sheathed plastic bushing of afterbody 20 of the glass pipe shaft 12 in glue head dropper 10, permissible
Play the effect of the afterbody of protective glass pipe shaft 12, another opening 24 of plastic bushing 20 is tip simultaneously, due to plastic sheath
The material of pipe 20 is softer with respect to glass, consequently facilitating being drawn onto bottom of bottle reagent.With respect to traditional glue head dropper, this brood lac head drips
Tube assembly uses more convenient.
Embodiment described above only have expressed several embodiments of the present utility model, and its description is more concrete and detailed,
But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that it is common for this area
For technical staff, without departing from the concept of the premise utility, some deformation can also be made and improve, these all belong to
In protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be defined by claims.
