[0052] The bottle cap structure and the pneumatic transmission bottle provided by the present application are exemplarily described below in conjunction with specific embodiments.

[0053] First, as Figure 1 and Figure 2 As shown, the bottle cap structure 1 provided in the embodiment of the present application is suitable for a bottle body 2 having an annular groove 21 on the inner side of a bottle mouth, comprising a cover body 11, a plurality of elastic fasteners 12, a movable portion 13 and a driving assembly 14; a receiving groove 111 is provided on one side of the cover body 11; a plurality of elastic fasteners 12 are arranged circumferentially around the receiving groove 111; the movable portion 13 is slidably arranged in the receiving groove 111; the driving assembly 14 has a driving portion 141, the driving portion 141 passes through the cover body 11 from a side of the cover body 11 away from the receiving groove 111 and is connected to the movable portion 13, and the driving portion 141 can be axially moved relative to the cover body 11 The movable portion 13 moves in the direction of the bottle body 11 so as to drive the movable portion 13 to switch between extending out of the accommodating groove 111 and retracting into the accommodating groove 111; the plurality of elastic fasteners 12 are used to extend into the bottle mouth so that the cover body 11 is covered on the bottle mouth. When the movable portion 13 is retracted into the accommodating groove 111, the movable portion 13 is disengaged from the plurality of elastic fasteners 12, and the plurality of elastic fasteners 12 are in a retracted state disengaged from the annular groove 21 under the action of their own elastic force; when the movable portion 13 is extended out of the accommodating groove 111, the movable portion 13 squeezes the plurality of elastic fasteners 12 and makes the plurality of elastic fasteners 12 in an expanded state engaged with the annular groove 21.

[0054] In this embodiment, the driving part 141 is axially moved relative to the cover body 11, so that the movable part 13 extends out of the receiving groove 111 or retracts into the receiving groove 111. When the cover body 11 retracts into the receiving groove 111, the movable part 13 is out of contact with the multiple elastic fasteners 12, and the multiple elastic fasteners 12 are in a retracted state under the action of their own elastic force. At this time, the bottle cap structure 1 can be extended into the bottle body 2 or the bottle cap structure 1 can be withdrawn from the bottle body 2, so that the bottle body 2 can be loaded and unloaded with materials. When the cover body 11 extends out of the receiving groove 111, the movable part 13 squeezes the multiple elastic fasteners 12 and makes the multiple elastic fasteners 12 in an expanded state, and the multiple elastic fasteners 12 cooperate and clamp with the annular groove 21 in the bottle body 2, so that the bottle cap structure 1 seals the opening of the bottle body 2. The bottle cap structure 1 provided in the present application has a simple overall structure, can be applied to the bottle body 2 with an annular groove 21 inside, and is simple to operate, and the sealing state is relatively stable. During transportation, it will not be easily loosened, causing the material to spill out.

[0055] Among them, the bottle cap structure 1 provided in the present application can be used in a pneumatic transmission bottle of a pneumatic transmission system to prevent the material in the pneumatic transmission bottle from spilling out and contaminating the pipeline and the transmission mechanism.

[0056] The driving unit 141 can be driven to move by an artificial external force, or can be driven to move by a motor or other means.

[0057] In one embodiment, if Figure 2 , Figure 4 and Figure 5 As shown, the driving assembly 14 also includes an elastic member 142, which is disposed in the accommodating groove 111 and located between the cover body 11 and the movable portion 13; wherein, when the multiple fasteners are in a folded state, the elastic member 142 is compressed and is in an energy storage state; when the multiple fasteners are in an unfolded state, the elastic member 142 is in an energy release state.

[0058] In the above embodiment, the elastic member 142 is mainly used to make the cover body 11 and the movable part 13 have a relative force through its own elastic force. Among them, when the driving part 141 is under the action of external force, the movable part 13 moves toward the receiving groove 111, and the movable part 13 gradually squeezes the elastic member 142 until the elastic member 142 is compressed and is in an energy storage state, and the multiple fasteners are in a retracted state, so as to extend the bottle cap structure 1 into the bottle body 2 or make the bottle cap structure 1 withdraw from the bottle body 2. When the force on the driving part 141 is released, the elastic member 142 relies on its own elastic force to drive the movable part 13 to move out of the receiving groove 111, until the driving part 141 extends out of the receiving groove 111 and makes the multiple elastic fasteners 12 in the unfolded state, and the multiple elastic fasteners 12 cooperate and clamp with the annular clamping groove 21 in the bottle body 2, so that the bottle cap structure 1 seals the opening of the bottle body 2.

[0059] Exemplarily, the elastic member 142 may be a spring, a reed, a rubber ball, etc.

[0060] In a specific embodiment, Figure 2 As shown, a mounting groove 131 is provided on one side of the movable portion 13 facing the elastic member 142 , one end of the elastic member 142 is disposed in the mounting groove 131 , and the other end is connected to the side of the accommodating groove 111 facing the movable portion 13 .

[0061] In the above embodiment, the mounting groove 131 is mainly used for mounting the elastic member 142 , ensuring that the elastic member 142 can be firmly mounted between the cover 11 and the movable portion 13 , and enabling the elastic member 142 to exert its elastic characteristics when subjected to force.

[0062] In a specific embodiment, Figure 2 , Figure 4 and Figure 5 As shown, the elastic member 142 is a spring, and the spring is sleeved on the outer circumference of the driving portion 141 .

[0063] Through the arrangement of the above structure, the elastic member 142 is specifically a spring, and is sleeved on the outer circumference of the driving part 141, and the spring and the driving part 141 are both located in the installation groove 131 to improve the stability of the overall movement.

[0064] In another embodiment, a threaded hole communicating with the receiving groove 111 is disposed on the cover body 11 , and a threaded section corresponding to the threaded hole is disposed on the peripheral side of the driving portion 141 .

[0065] By setting the above structure, the driving part 141 is rotated to move back and forth along its own axis to drive the movable part 13 to switch between extending out of the accommodating groove 111 and retracting into the accommodating groove 111. The threaded structure between the cover body 11 and the driving part 141 makes the connection more firm and stable, and is not easy to loosen or fall off.

[0066] In one embodiment, if Figure 1 and Figure 2 As shown, the fastener includes a fastener body 121 and a fastener portion 122 connected to each other. The fastener portion 122 is provided with a guide surface on one side facing the movable portion 13 , and the fastener portion 122 is used to cooperate and clamp with the annular slot 21 of the bottle body 2 on the side facing away from the movable portion 13 .

[0067] In the above embodiment, the guide surface of the buckle portion 122 is arranged on one side facing the movable portion 13, so that the movable portion 13 can more smoothly press the elastic buckle 12 to avoid being stuck.

[0068] In one embodiment, if Figure 1 and Figure 2 As shown, a force applying member 143 is disposed at one end of the driving portion away from the movable portion 13 .

[0069] In the above embodiment, the force applying member 143 is mainly used to provide power to the driving part 141 to drive the movable part 13 to move. Exemplarily, the force applying member 143 can be a handle for manual driving.

[0070] In one embodiment, if Figure 2 As shown, the driving portion 141 is connected to the movable portion 13 via a fastening structure 15 .

[0071] Specifically, the fastening structure 15 includes a bolt 151 and a nut 152, a first mounting hole is provided inside the driving part 141, and a second mounting hole corresponding to the first mounting hole is provided inside the movable part 13; wherein, the bolt 151 is located in the first mounting hole, the nut 152 is located in the second mounting hole, and one end of the bolt 151 extends into the second mounting hole and is threadedly connected with the nut 152.

[0072] The above-mentioned structural arrangement facilitates the installation and disassembly of the driving part 141 , the movable part 13 and the cover body 11 .

[0073] Of course, in another embodiment, the bolt 151 is located in the second mounting hole, the nut 152 is located in the first mounting hole, and one end of the bolt 151 extends into the first mounting hole and is threadedly connected to the nut 152. This embodiment can also achieve the above effect.

[0074] In one embodiment, if Figure 1 and Figure 2 As shown, the movable portion 13 is a cylindrical structure, and one end of the movable portion 13 that contacts the plurality of elastic fasteners 12 has a guide surface.

[0075] Through the arrangement of the above structure, one end of the movable portion 13 that contacts the plurality of elastic fasteners 12 has a guide surface, so that the movable portion 13 can more smoothly press the elastic fasteners 12 to avoid jamming.

[0076] Specifically, Figure 1 As shown, the cover body 11 may also be a cylindrical structure.

[0077] Second, as Figure 4 and Figure 5 As shown, the present application also provides a pneumatic transmission bottle, comprising: a bottle cap structure 1 and a bottle body 2 as described in the above embodiment, wherein an annular groove 21 is circumferentially arranged on the inner side of the bottle mouth of the bottle body 2; wherein the multiple fasteners of the bottle cap structure 1 can be in an expanded state and cooperate with the annular groove 21 of the bottle body 2 to clamp under the action of the movable part 13, and in a folded state and detach from the annular groove 21 of the bottle body 2.

[0078] In the embodiment of the present application, since the pneumatic transmission bottle adopts the bottle cap structure 1 in the above embodiment, it also has the advantages and benefits brought by the above bottle cap structure 1, that is, it is easy to operate, the sealing state is relatively stable, and it will not easily loosen during transportation, causing the material to spill.
