[0037] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be described in further detail below with reference to the drawings.
[0038] The utility model provides a double -layer sealing cover, improve the sealing of sealing cover and reagent bottle, reduce the occurrence of liquid overflow in reagent bottle.
[0039] Embodiment 1:
[0040] As Figures 1-5 A double -layer sealing cover as shown, it includes inner cover 100.
[0041] The inner cover 100 and the bottle mouth of bottle body H are screw connection, the bottle mouth of bottle body H is provided with external thread, and the inner wall of inner cover 100 is provided with internal thread, the inner cover 100 knob is on the bottle mouth of bottle body H, and the inner cover 100 is provided with the cavity 110 of placing sealing gasket L, and the inner wall of inner cover 100 is provided with limiting convex part 120 matched with the limiting groove H-1 of the upper edge outer wall of bottle mouth.
[0042] As preferred, in the embodiment, the cover surface of inner cover 100 is provided with a plurality of sampling holes 160, and the taking device (such as a syringe) can pass through the sampling hole 160, the sealing gasket L and then enter the reagent bottle to extract the reagent in the reagent bottle.
[0043] As preferred, in the embodiment, the limiting convex part 120 is annular structure, and the outer wall corner is provided with round chamfer, so that the edge of limiting convex part 120 is smooth, and the limiting convex part 120 is conveniently clamped into the limiting groove H-1.
[0044] As Figure 2 shown, due to the bottle mouth, the part located at the upper part of the limiting groove H-1 is convex relative to the limiting groove H-1, so that the limiting convex part 120 is difficult to be clamped into the limiting groove H-1 by passing the convex part.
[0045] Therefore, as preferred, in the present embodiment, the rear part of the limiting convex part 120 provided on the inner wall of the inner cover 100 is provided with a yielding groove 140; when the limiting convex part 120 cooperates with the limiting groove H-1 of the outer wall of the upper edge of the bottle mouth, the limiting convex part 120 slightly deforms towards the yielding groove 140, so that the limiting convex part 120 can smoothly pass the convex part at the upper part of the limiting groove H-1, and after the limiting convex part 120 passes the convex part at the upper part of the limiting groove H-1, the limiting convex part 120 resets to be clamped into the limiting groove H-1.
[0046] When the limiting convex part 120 is clamped into the limiting groove H-1, the sealing gasket L is tightly compressed on the bottle mouth of the bottle body H, solving the problem that the convex ring at the lower edge of the bottle mouth thread of the traditional reagent bottle has low machining precision, so that the clamping force of the clamp of some double-layer covers cannot tightly clamp the convex ring on the reagent bottle, resulting in the problem of liquid overflow in the reagent bottle.
[0047] Further, the anti-theft cover 200 is further provided on the basis of the inner cover 100, the outer wall of the inner cover 100 is provided with external threads, the inner wall of the anti-theft cover 200 is provided with internal threads, and the inner cover 100 and the anti-theft cover 200 are connected by threads; the inner cover 100 is provided with a limiting ring 130 at the lower part of the external threads; the anti-theft cover 200 includes a cover body 210 rotating on the inner cover 100, an anti-theft ring 220 being limited by the limiting ring 130 and unable to move vertically, and an anti-theft rib 230 provided between the anti-theft ring 220 and the cover body 210; a plurality of through-hole grooves 220b are equidistantly provided on the circumferential outer wall of the anti-theft ring 220, and an inclined abutting part 220c is provided in the through-hole groove 220b and abuts against the bottom of the limiting ring 130, so as to realize the axial limitation of the anti-theft ring 220 by the limiting ring 130.
[0048] The anti-theft ring 220 is provided with a plurality of forward rotation blocking grooves 220a equidistantly, and the cover body 210 is provided with a forward rotation blocking block 210a extending into the forward rotation blocking groove 220a.
[0049] Wherein, the cover 210 and the anti-theft ring 220 are connected into a whole through the anti-theft rib 230, when this whole is spiraled forwardly and reaches the screwing limit from the beginning, the forward rotation blocking slot 220a will limit the movement of the forward rotation blocking block 210a in it, prevent the cover 210 and the anti-theft ring 220 from being dislocated, cause the anti-theft rib 230 to break, when the cover 210 is rotated counterclockwise, the abutting portion on the anti-theft ring 220 cannot move vertically upward along with the cover 210 due to being clamped by the limiting ring 130, when the cover 210 is spirally moved to a certain height, the anti-theft rib 230 breaks under the stretching action, the cover 210 and the anti-theft ring 220 can be directly separated, at the same time, the breakage of the anti-theft rib 230 due to the rotation loosening of the anti-theft ring 220 under various environmental use conditions is prevented, the integrity of the product is effectively ensured, as preferred, in the embodiment, the left side of the forward rotation blocking slot 220a and the left side of the forward rotation blocking block 210a are vertical surfaces, the right side of the forward rotation blocking slot 220a and the right side of the forward rotation blocking block 210a are inclined surfaces.
[0050] Example 2:
[0051] As shown in Figure 2 , the bottle body H is provided with a bottle body limiting ring H-2 at the neck portion, which is located at the inner side of the inner wall of the lower part of the inner cover 100.
[0052] As shown in Figure 6 and Figure 7 , the inner wall of the lower part of the inner cover 100 is provided with a plurality of limiting blocks 150 for embedding the end face of the bottle body limiting ring H-2; the surface of the limiting block 150 is provided with a groove for embedding the end face of the bottle body limiting ring H-2.
[0053] When the inner cover 100 is screwed onto the bottle mouth of the bottle body H, the groove of the limiting block 150 of the inner wall of the lower part of the inner cover 100 is embedded with the bottle body limiting ring H-2, which further serves the purpose of stable combination of the inner cover 100 and the bottle body H.
[0054] Example 3:
[0055] As shown in Figures 8-10As shown, a double-layer sealing cover, the outer wall of the limiting ring 130 is provided with several equidistant one-way tooth grooves 130a, the inner wall of the anti-theft ring 220 is provided with several one-way tooth blocks 220d embedded into the one-way tooth grooves 130a, since the existing anti-theft cover 200 is unscrewed counterclockwise, the anti-theft rib 230 is basically limited by the limiting ring 130 and the anti-theft ring 220, and is pulled open by the distance of the thread of the cover body 210, since this limiting structure only limits the upward movement of the anti-theft ring 220, and does not limit its rotation, for example, the bumping and vibration of long-distance transportation, there is a risk of easily damaging the anti-theft rib 230, therefore, by setting the above limiting structure, when the cover body 210 and the anti-theft ring 220 are screwed into the inner cover 100, the one-way tooth grooves 130a and the one-way tooth blocks 220d are tightly matched, so that the cover body 210 is limited to be unscrewed counterclockwise under the condition of non-human or mechanical force, effectively ensuring the integrity of the anti-theft rib 230, thereby ensuring the integrity and stability of the product in special environment.
[0056] Although the present application has been described with reference to the embodiments above in the foregoing description, it is to be understood that various modifications can be made without departing from the scope of the present application. In particular, the features of the embodiments of the present application can be used in any combination without departing from the scope of the present application.
