Technical Field

[0001] This utility model belongs to the field of packaging technology, specifically a doctoral cap-shaped cap structure. Background Technology

[0002] It is widely used in packaging such as honey bottles, pear syrup bottles, and loquat syrup bottles, and is also used in cosmetic packaging, such as lotion bottles, essence bottles, facial cleanser bottles, and toothpaste tubes, making it more convenient and quick to use.

[0003] Currently, some doctoral cap-shaped caps are not easy to open, requiring considerable force or special tools, which is inconvenient for users. The structural design of the cap does not fully consider ergonomics, or sacrifices ease of use in pursuit of sealing performance and sandproof effect.

[0004] Therefore, a doctoral cap-shaped cap structure is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a doctoral cap-shaped cover structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The doctoral cap-shaped cap structure of this utility model includes a bottle cap and a first circular block. The outer wall of the bottle cap is fixedly connected with several anti-slip teeth. An inclined rod is fixedly connected to the upper surface of the bottle cap. A support rod is fixedly connected to one side of the inclined rod. A circular connecting block is movably sleeved on the surface of the support rod. A first connecting rod is movably sleeved on one side of the circular connecting block and the support rod. Circular fixing blocks are fixedly sleeved on both sides of the first connecting rod. A lever is fixedly connected to the upper surface of the circular connecting block. A second connecting rod is fixedly connected to one side of the first circular block.

[0007] Preferably, a first ring is fixedly connected to the upper surface of the bottle cap, a first rubber ring is fixedly connected to the upper surface of the first ring, a first hollow tube is fixedly connected to the upper surface of the bottle cap, a second ring is fixedly connected to the upper surface of the first round block, and a water outlet is provided through the surface of the first hollow tube.

[0008] Preferably, a second rubber ring is fixedly connected to the upper surface of the first circular block, a second hollow tube is fixedly connected to the upper surface of the first circular block, and a plurality of third rubber rings are fixedly sleeved on the surface of the second hollow tube.

[0009] Preferably, a third ring is fixedly sleeved on the outer wall of the second ring, and a first groove is formed on the upper surface of the third ring. A fourth ring is fixedly sleeved on the outer wall of the first ring, and a second groove is formed on the upper surface of the fourth ring.

[0010] Preferably, a third connecting block is fixedly connected to the upper surface of the bottle cap, and a first connecting block is fixedly connected to one side of the third connecting block.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] Please see Figure 1 - Figure 6 This utility model provides a doctoral cap-shaped cap structure, including a bottle cap 102 and a first circular block 601. Several anti-slip teeth 101 are fixedly connected to the outer wall of the bottle cap 102. An inclined rod 201 is fixedly connected to the upper surface of the bottle cap 102. A support rod 202 is fixedly connected to one side of the inclined rod 201. A circular ring connecting block 206 is movably sleeved on the surface of the support rod 202. A first connecting rod 203 is movably sleeved on one side of the circular ring connecting block 206 and the support rod 202. Circular ring fixing blocks 204 are fixedly sleeved on both sides of the first connecting rod 203. A lever 205 is fixedly connected to the upper surface of the circular ring connecting block 206. A second connecting rod 207 is fixedly connected to one side of the first circular block 601.

[0020] During operation, the bottle cap 102 serves as the basic load-bearing component. An inclined rod 201, fixedly connected above it, provides rigid support to the support rod 202, forming an overall force-bearing frame. When the bottle cap 102 needs to be opened, the user applies force to one side of the lever 205. The lever 205, through its fixed connection with the annular connecting block 206, transmits the force to the annular connecting block 206. Since the annular connecting block 206 is movably sleeved on the surface of the support rod 202, it can slide along the axis of the support rod 202 or rotate slightly around the rod, thereby driving the first connecting rod 203, which is movably sleeved with it, to move. The first connecting rod 203 has two sides... The circular fixing block 204 serves as a limit to prevent the first connecting rod 203 from moving axially during operation. The first connecting rod 203 and the support rod 202 are movably sleeved together, providing freedom of movement for the rod and avoiding jamming between components. The overall material is PP material, which has good chemical resistance, high toughness and impact resistance, and can withstand a certain amount of external pressure and friction, and is not easy to break or be damaged. Its design is flexible and easy to open and close. It is also often equipped with silicone valves, gaskets, etc., and has good sealing and anti-drip performance. The teeth inside the bottle cap 102 and the silicone valve and gasket facilitate opening and closing and have good sealing and anti-drip performance.

[0021] Furthermore, such as Figure 1 and Figure 5 A first ring 301 is fixedly connected to the upper surface of the bottle cap 102 shown. A first rubber ring 302 is fixedly connected to the upper surface of the first ring 301. A first hollow tube 303 is fixedly connected to the upper surface of the bottle cap 102. A second ring 304 is fixedly connected to the upper surface of the first round block 601. A water outlet 401 is provided through the surface of the first hollow tube 303. A second rubber ring 501 is fixedly connected to the upper surface of the first round block 601. A second hollow tube 502 is fixedly connected to the upper surface of the first round block 601. Several third rubber rings 503 are fixedly sleeved on the surface of the second hollow tube 502.

[0022] During operation, the second hollow tube 502 is inserted into the first hollow tube 303 fixed on the bottle cap 102. At this time, several third rubber rings 503 on the surface of the second hollow tube 502 are tightly fitted with the inner wall of the first hollow tube 303 to form a multi-layer radial seal, preventing leakage during fluid transmission. The second rubber rings 501 on the first circular block 601 and the first rubber rings 302 on the bottle cap 102 are squeezed against each other to form an end face seal, further enhancing the overall sealing effect. When fluid needs to be transported, the fluid can enter through the second hollow tube 502, pass through the first hollow tube 303, and be discharged from the outlet 401 penetrating its surface. The overall structure takes into account both the flexibility of power linkage and the sealing performance of fluid transmission.

[0023] Furthermore, such as Figure 1 - Figure 6A third ring 602 is fixedly sleeved on the outer wall of the second ring 304. A first groove 603 is formed on the upper surface of the third ring 602. A fourth ring 801 is fixedly sleeved on the outer wall of the first ring 301. A second groove 802 is formed on the upper surface of the fourth ring 801. A third connecting block 704 is fixedly connected to the upper surface of the bottle cap 102. A first connecting block 701 is fixedly connected to one side of the third connecting block 704. A second connecting block 702 is fixedly connected to both sides of the inner wall of the third connecting block 704 and the first connecting block 701. A V-shaped connecting block 703 is fixedly connected to one side of the second connecting block 702. The second connecting rod 207 and the lever 205 are on the same level. The second ring 304 and the first rubber ring 302 are compatible. The first groove 603 and the second groove 802 are compatible.

[0024] During operation, the upper surface of the bottle cap 102 forms an initial frame with the first connecting block 701 on one side via a fixed third connecting block 704. To address the issue of the frame being susceptible to deformation under external forces, second connecting blocks 702 are fixed at both ends of the inner wall connection between the third connecting block 704 and the first connecting block 701. This creates two sets of symmetrical triangular statically determinate structures. The mechanical properties of the triangular structure can evenly distribute the lateral forces and torques generated during subsequent power transmission to the bottle cap 102 body, completely avoiding frame bending or displacement caused by local stress concentration. The V-shaped connecting block 703 fixed to the outside of the second connecting block 702 further enhances the frame's resistance to torsion and lateral bending through the force decomposition effect of the included angle. Even under frequent operation or slight impact, the overall structural position remains stable. The material is formed by injecting molten plastic into the mold cavity, which is then cooled and solidified to form a plastic flip cap. This allows for high-precision and rapid production, precise control of temperature, pressure, and cooling processes, and ensures product dimensional accuracy and quality stability. Working principle: The user opens the first round block 601 by lever 205, and water is discharged from the outlet 401 through the first hollow tube 303. The tilting rod 201 and the fixed support rod 202 form a power support base. When the device is closed, the first round block 601 flips towards the bottle cap 102, the first groove 603 and the second groove 802 are sealed and fitted, the second ring 304 and the first rubber ring 302 are sealed and fitted, and at the same time, the second hollow tube 502 is inserted into the first hollow tube 303. The third rubber ring 503 has a sealing effect on the first hollow tube 303. The device can be reset by applying force in the opposite direction. The V-shaped connecting block 703 frame ensures stability throughout the process.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
