Description

Technical Field

[0001] The utility model relates to the technical field of drinking utensils, and more particularly to a connection structure between a handle and a cup body and a plastic water cup with the structure. Background Art

[0002] The advantages of plastic water cups are that they are light and easy to carry, durable, not easy to break, low cost, easy to clean and reusable. Therefore, they are widely favored by people in many occasions, especially when traveling. The cup body and handle of a traditional plastic water cup are generally molded in one piece. Based on the characteristics of the plastic material, it is obvious that the plastic water cup cannot use the same welding method as the stainless steel cup to fix the cup body and handle. Therefore, special molds are generally used for injection molding. However, due to the existence of the mold parting surface, the molded plastic water cup often has a parting line on it, affecting the appearance quality of the entire water cup. Separate molding of the cup body and handle can eliminate the parting line, thereby improving the overall appearance quality and avoiding the influence of the parting line on the aesthetics.

[0003] Here, taking the Chinese patent with publication number CN202619203U and patent name "cup with detachable handle" as an example, the water cup includes a cup body and a handle. There is a hole on the cup body, the size of which is just right for the thickness of the handle. A rubber sleeve is used, one end of which is inserted into the cup body and tightly connected to the cup body, and the other end is covered with the end of the handle and tightly connected to the handle. The rubber sleeve connects the cup body and the handle together, and also includes a pull ring, which is movably connected to the handle.

[0004] After a hole is opened on the water cup, the rubber sleeve is inserted into the hole, and then the handle is embedded in the rubber sleeve. The rubber sleeve is used to connect the cup body and the handle. The rubber sleeve not only acts as a connector but also has a sealing effect to prevent the beverage in the cup body from leaking out of the hole. However, there is a problem of poor stability of the handle. When the handle is pulled away from the cup body, the handle is likely to cause axial movement between the rubber sleeve and the hole, or even directly detach from the rubber sleeve, which not only destroys the sealing but also affects normal use. Secondly, there is only a single docking point between the cup handle and the cup body, which makes the handle easily deflect with the docking point as the rotation axis, which also affects normal use. Utility Model Content

[0005] In view of the above situation, in order to overcome the problem that the connection between the handle and the cup body of the plastic water cup with a detachable handle in the above-mentioned prior art is poor, when the handle is pulled away from the cup body, the handle and the rubber sleeve are easily separated from the cup body and the sealing is destroyed, and there is only a single docking point between the cup handle and the cup body, which makes the handle easily deflected about the docking point as the rotation axis, affecting normal use. The purpose of the utility model is to provide a handle that is firmly connected to the cup body and has good sealing at the docking position, thereby avoiding affecting normal use and significantly improving the user experience, and at the same time having a highly aesthetic connection structure between the cup handle and the cup body and a plastic water cup having such a structure.

[0030] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] In the description of the present utility model, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of simplifying the description, and do not indicate or imply that the directions are specific directions that must be possessed and specific directions, structures, and operations, and therefore should not be understood as limitations on the present utility model.

[0032] like Figure 2 , Figure 3 as well as Figure 8 and Fig. 9As shown, the utility model firstly relates to a connection structure between a handle and a cup body, which is used for a plastic water cup with a handle 7, and comprises a fixed clamp 1, an assembly hole 2, a water-sealing plug 3 and a movable clamp, wherein the fixed clamp 1 is formed on the outer wall of the cup body 4 of the configured plastic water cup, the assembly hole 2 is located on the cup body 4 below the fixed clamp 1, the assembly hole 2 is a through hole, which passes through the inside and outside of the cup body 4, the water-sealing plug 3 is embedded in the assembly hole 2 from the inside of the cup body 4, and a step is formed between the water-sealing plug 3 and the inner wall of the cup body 4, and the step is used to limit the movement of the water-sealing plug 3 to the outside of the cup body 4, so that it maintains a stable interference fit state with the assembly hole 2, and an installation cavity 301 is opened in the water-sealing plug 3. 301 is also a through-hole structure, which passes through both ends of the water-sealing plug 3 to connect the inside and outside of the cup body 4. The movable clamp includes a front connector 5 and a rear connector 6. The front connector 5 is embedded in the installation cavity 301 from the inside of the cup body 4, and extends to the outside of the cup body 4 and is detachably fixed to the rear connector 6. From an external perspective, this part of the front connector 5 is a protrusion on the outer wall of the cup body 4, and the front connector 5 also forms a step with the water-sealing plug 3, thereby limiting the movement of the front connector 5 to the outside of the cup body 4, and maintaining a stable connection with the water-sealing plug 3. An interference fit is formed between the assembly hole 2, the water-sealing plug 3 and the front connector 5 to prevent the beverage contained in the cup body 4 from leaking out between the assembly positions to maintain sealing. The upper connecting end of the handle 7 is fixed to the fixed clamp, and the lower connecting end of the handle 7 is fixed to the movable clamp. The handle 7 of the plastic water cup equipped with the connection structure of the utility model forms two connection positions with the cup body 4 through the fixed clamp 1, and the cooperation of the connected rear connecting body 6 and the front connecting body 5. The two-point positioning is used to effectively prevent the handle 7 from being offset or rotating relative to the cup body 4 after assembly, thereby ensuring the stability of the connection between the handle 7 and the cup body 4. When the handle 7 is subjected to an external force in a direction away from the cup body 4, the step cooperation between the water sealing plug 3 and the inner wall of the cup body 4, and the step cooperation between the front connecting body 5 and the water sealing plug 3 prevent the front connecting body 5, the water sealing plug 3 and the cup body 4 from being offset or rotating relative to each other. Relative movement can avoid dislocation due to relative movement, thereby preventing the sealing of the cup body 4 at the assembly hole 2 from being destroyed, ensuring the normal use of the configured plastic water cup, and significantly improving the user experience. In addition, the cup body 4 and the handle 7 are connected by using the fixed clamp 1, the assembly hole 2, the water sealing plug 3 and the movable clamp, so that the cup body 4 and the handle 7 do not need to be integrally injection molded. When the cup body 4 is molded and demolded, first use two sets of slider mechanisms to respectively extract them from the fixed clamp 1 and the assembly hole 2, and then use the ejection mechanism to eject them from the cavity. The corresponding handle 7 can be directly ejected from the cavity by the ejection mechanism, which solves the problem of the presence of the joining line on the molded cup body 4 and the handle 7, and greatly improves the overall appearance quality.

[0033] like Figure 4 , Figure 8 and Fig. 9As shown, an annular groove 302 is provided on the outer peripheral wall of the water sealing plug 3, and the hole wall of the assembly hole 2 is embedded in the annular groove 302 and forms a step with the annular groove 302, thereby limiting the position from the front and back sides, so that after being inserted into the assembly hole 2, it is more difficult for the water sealing plug 3 to move to the outside through the assembly hole 2.

[0034] like Figure 6 , Figure 8 and Fig. 9 As shown, a slot 601 is provided at one end of the rear connector 6 close to the front connector 5, and the portion of the front connector 5 outside the cup body 4 is embedded in the slot 601 and plugged into the rear connector 6, and the plug-in is a straight-insert detachable connection, which makes the assembly of the front connector 5 and the rear connector 6 more convenient and labor-saving, thereby improving the assembly efficiency.

[0035] like Figure 5 , Figure 6 , Figure 8 and Fig. 9 An outer circumferential wall of the rear connector 6 is provided with an outer positioning hole 602 which passes through the slot 601, and an inner positioning hole 502a which is opposite to the outer positioning hole 602 is provided on the front connector 5. The rear connector 6 and the front connector 5 are fixed by a threaded fastener 8 which passes through the outer positioning hole 602 and the inner positioning hole 502a. The self-locking property of the threaded connection is utilized to enable the front connector 5 and the rear connector 6 to remain more firmly fixed after being plugged in, thereby reducing the possibility of separation due to accidental force.

[0036] like Figure 5 , Figure 8 and Fig. 9 As shown, the front connector 5 includes a base 501 and a connecting piece 502, the materials of the base 501 and the connecting piece 502 are plastic and metal respectively, the base 501 is wrapped around the connecting piece 502 and fixed as a whole by hot-melt bonding, the base 501 is embedded in the installation cavity 301 of the water-sealing plug 3, and a boss 501a is formed on its outer wall, and a step is formed between the boss 501a and the water-sealing plug 3. Preferably, the boss 501a is in the shape of a ring, so that the force between the base 501 and the water-sealing plug 3 is evenly distributed, preventing the base 501 from tilting or deflecting relative to the water-sealing plug 3, and protecting the sealing between the water-sealing plug 3, the connecting piece 502 extends to the outside of the cup body 4 and is detachably fixed to the rear connector 6, and the connecting piece 502 made of metal has a high structural strength, and provides stable support for the rear connector 6 inside when mated.

[0037] like Figures 7 to 9 As shown, the handle 7 is provided with an inner slot 701 opposite to the fixed clip 1 and the rear connector 6. The fixed clip 1 and the rear connector 6 are embedded in the corresponding inner slot 701 and plugged into the handle 7. This plug-in fit is also a direct plug-in fit, which makes assembly more convenient and labor-saving, thereby improving assembly efficiency.

[0038] like Figure 2 , Figure 6 and Figure 7 As shown, the outer peripheral walls of the fixed card 1 and the rear connector 6 have at least one banner a1 arranged along their respective length directions, and the side walls of the inner slot 701 are provided with guide grooves 701a corresponding to the banners a1, and the banners a1 are embedded in the corresponding guide grooves 701a. Based on the above arrangement, each banner a1 is used to form a non-circular docking position projection surface between the fixed card 1, the rear connector 6 and the inner slot 701 of the handle 7, which effectively limits the rotation of the handle 7 relative to the fixed card 1 and the rear connector 6 during the assembly process, thereby reducing the difficulty of assembly. At the same time, the banner a1 also has a guiding function to ensure the correct installation of the fixed card 1 and the rear connector 6, especially to keep the slot 601 in the rear connector 6 directly opposite to the front connector 5.

[0039] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, at least one outer slot 702 penetrating the inner slot 701 is provided on the outer peripheral wall of the handle 7, and a card block a2 corresponding to the outer slot 702 is provided on the outer peripheral wall of the fixed card component 1 and the rear connecting body 6. After the fixed card component 1 and the rear connecting body 6 are aligned with the guide groove 701a in the inner slot 701 in the banner a1, the card block a2 is also located in the extension direction of the outer slot 702. As the handle 7 moves toward the fixed card block a2 and the front connecting body 5, the card block a2 can be directly embedded in the corresponding outer slot 702 during the movement. In this embedded state, abutment is formed between the groove wall of the outer slot 702 and the outer wall of the card block a2, which effectively limits the axial movement of the fixed card component 1 and the rear connecting body 6 relative to the handle 7, thereby realizing the fixation of the fixed card component 1, the rear connecting body 6 and the handle 7, and improving the stability of the assembly.

[0040] Furthermore, since a portion of the water-sealing plug 3 is located inside the cup body 4, when the cup body 4 is filled with beverages, it is in direct contact with the beverages, and therefore the material of the water-sealing plug 3 is configured as food-grade silicone. Food-grade silicone has excellent high-temperature resistance, low-temperature resistance, and chemical stability, and can prevent the production of harmful substances when in contact with hot beverages, thereby ensuring healthy drinking, and is not prone to deformation that affects the sealing between the assembly hole 2. It also has elasticity, thereby achieving an interference fit with the assembly hole 2, thereby effectively preventing leakage of beverages.

[0041] Combination Figures 1 to 9The utility model also relates to a plastic water cup with the above-mentioned connection structure, which includes a cup body 4, a handle 7 and a cup cover 9. The cup body 4, the handle 7 and the cup cover 9 are made of plastic. The cup cover 9 is covered on the opening of the cup body 4. During molding, the cup body 4 and the cup handle are molded separately by a mold. The molded cup body 4 has a fixed clamp 1 and an assembly hole 2. After the cup body 4 is molded, two sets of slider mechanisms are first used to separate from the fixed clamp 1 and the assembly hole 2 respectively, and then the ejection mechanism is used to eject the cavity. The handle 7 can be directly ejected from the cavity under the action of the ejection mechanism. During assembly, the front connector 5 of the above-mentioned connection structure is first embedded in the installation cavity 301 of the water sealing plug 3 until the connecting piece 502 passes through the installation cavity 301, and the boss 501a of the base 501 is aligned with the periphery of the installation cavity 301. The outer walls of the sides are abutted against each other to achieve a step fit, and then the water-sealing plug 3 is embedded in the assembly hole 2 from the cup body 4 until the hole wall of the assembly hole 2 is embedded in its annular groove 302 to form a step fit. At this time, the connecting piece 502 of the front connecting body 5 passes through the assembly hole 2 and extends to the outside of the cup body. At the same time, the rear connecting body 6 is sleeved onto the front connecting body 5 through the slot 601, and then the threaded fastener 8 is used to penetrate the outer positioning hole 602 and the inner positioning hole 502a to fix it. Then, the fixed clip 1 and the banner a1 of the rear connecting body 6 are respectively embedded in the inner slot 701 relative to the guide groove 701a on the wall of the inner slot 701 at the upper connecting end and the lower connecting end of the handle 7. At the same time, the block a2 can be directly embedded in the outer slot 702 during the movement, so that the installation and fixation of the handle 7 and the cup body 4 can be completed.

[0042] The above embodiments and descriptions are only for explaining the principle and the best embodiment of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
