Description
Technical Field
The utility model relates to a sealing device of kit nozzle, concretely relates to sealed lid reaches nozzle rather than cooperation use.
Background
The kit is a common laboratory product and is used for storing reaction reagents. For liquid reagents, the kit is provided with a liquid outlet for dispensing the liquid from a reservoir within the kit. The outlet opening of the reagent vessel is usually connected to a tubular structure and a nozzle is provided to control the outlet. When the reagent box is used for storing a liquid reagent, the nozzle is sealed through the sealing cover, the conventional sealing cover adopts a thread design, the sealing performance is poor, and meanwhile, when the sealing cover is taken down in a rotating mode, the nozzle of the nozzle can be damaged, so that liquid outlet of the nozzle is not smooth or even cannot be realized.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a sealing cap that sealing performance is good and be difficult for droing reaches nozzle rather than cooperation use.
The utility model adopts the following technical scheme:
the utility model provides a sealed lid, its includes sealed lid body and sets up the nozzle seal hole that has the cecum on sealed lid body, the periphery in nozzle seal hole is provided with annular seal groove, the lateral wall of annular seal groove is provided with the annular seal boss that extends to the inslot.
Further, the nozzle seal hole is located at the center of the annular seal groove.
Further, the nozzle sealing hole comprises a connecting hole and a blind end hole.
Furthermore, the blind end hole is frustum-shaped.
Further, the connecting hole is cylindrical.
Furthermore, the sealing cover is made of an elastic sealing material.
Preferably, the sealing cover is made of silica gel.
The utility model provides a nozzle for kit with above-mentioned sealed lid cooperation is used, its includes the annular casing, set up at the end plate of annular casing one end, set up at the nozzle pipe at end plate center and set up the toper spout at nozzle pipe tip, still be provided with the annular flange around nozzle pipe periphery on the end plate, be provided with the liquid passage with the inside intercommunication of annular casing in nozzle pipe and the toper spout, enclose between nozzle pipe and the annular flange and close and form annular groove.
The beneficial effects of the utility model reside in that: the utility model discloses a sealed lid forms the double seal protection to the spout of nozzle and the annular flange of nozzle, is difficult for the weeping, and in addition, the sealed boss of annular in the annular seal groove extrudees the interference with the annular flange of nozzle, has both guaranteed the leakproofness, makes sealed lid be difficult for droing again.
Drawings
Fig. 1 is a schematic sectional view of the present invention.
Fig. 2 is a schematic sectional structure view of a reagent cartridge nozzle used in cooperation with the present invention.
Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention.
As shown in fig. 1, the sealing cover comprises a sealing cover body 1 and a nozzle sealing hole with a blind end, which is arranged on the sealing cover body 1, wherein an annular sealing groove 2 is arranged on the periphery of the nozzle sealing hole, and an annular sealing boss 3 extending into the groove is arranged on the side wall of the annular sealing groove 2. The nozzle seal hole is located at the center of the annular seal groove 2.
The nozzle sealing bore comprises a connecting bore 4 and a blind end bore 5. The blind end hole 5 is frustum-shaped. The connecting hole 4 is cylindrical. The sealing cover body 1 is cylindrical. The seal cap is made of an elastomeric sealing material, such as rubber. Preferably, the sealing cover is integrally formed by silica gel materials.
As shown in figure 2, the nozzle for the reagent kit matched with the sealing cover comprises an annular sleeve 2-1, an end plate 2-2 arranged at one end of the annular sleeve 2-1, a nozzle pipe 2-3 arranged at the center of the end plate 2-2 and a conical nozzle 2-4 arranged at the end part of the nozzle pipe 2-3, wherein an annular flange 2-5 surrounding the periphery of the nozzle pipe 2-3 is further arranged on the end plate 2-2, a liquid channel 2-6 communicated with the inside of the annular sleeve 2-1 is arranged in the nozzle pipe 2-3 and the conical nozzle 2-4, and an annular groove 2-7 is formed between the nozzle pipe 2-3 and the annular flange 2-5 in a surrounding manner.
The conical nozzle of the nozzle is designed to be conical, so that liquid is prevented from hanging and dripping. The nozzle pipe 2-3 is cylindrical, the outer side of the nozzle pipe is provided with an annular flange and an annular groove, the long and thin nozzle pipe is prevented from being damaged by external force, and the groove can also clamp the sealing cover when the sealing cover is installed, so that the sealing cover is not easy to fall off.
An annular buckling groove 2-8 is formed in the annular sleeve 2-1. The nozzle is matched with the buckle at the installation position of the reagent box spray pipe, and the spray pipe is inserted into the annular sleeve, so that the installation is convenient and direct. The liquid reagent is sprayed out from a liquid channel in the nozzle after passing through a liquid outlet and a spray pipe of the kit.
When the nozzle is combined with the sealing cover to realize sealing, the cylindrical connecting hole 4 is matched with the cylindrical nozzle pipe 2-3, and the frustum-shaped blind end hole is matched with the conical nozzle 2-4 to realize the sealing connection of the nozzle. The annular sealing groove is matched with the annular flange, and the annular sealing boss in the annular sealing groove compresses the annular flange. The sealing cover forms double sealing protection for the nozzle and the annular flange of the nozzle, liquid leakage is not easy to occur, and in addition, the annular sealing boss in the annular sealing groove is in extrusion interference with the annular flange of the nozzle, so that the sealing performance is ensured, and the sealing cover is not easy to fall off.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
