Description

[0001] The present application is a divisional application of the original application No. 202222674038X, the original application date is October 11, 2022, and the original invention creation name is "a cap screwing device". TECHNICAL FIELD

[0002] The utility model relates to a daily necessities tool, especially a cap screwing device. BACKGROUND

[0003] Some cans and bottle caps are very tight and difficult to unscrew. It is very laborious to unscrew the bottle cap with bare hands. Sometimes the bottle cap is too tight, and the hand is easy to slip between the bottle cap and the bottle, so that the bottle cap cannot be unscrewed. Even if a semi-wet cloth is used to cover the cap to increase the friction of the cloth, a lot of force is still needed to unscrew the cap.

[0004] The existing cap screwing device is usually a double handle structure. The double handle is provided to make force in two directions, so as to clamp and rotate the bottle cap. During the bottle opening process, force is needed not only for clamping the bottle cap, but also for rotating the bottle cap, so it is also laborious to screw. In order to make it easier for the hand to exert force, the front surface of the cap screwing device is first combined with the cap each time to try, and then the cap screwing device is turned over to cover the back surface to try, so as to determine which surface can be more compliant with the bottle cap. If the grip is not tight enough, the cap screwing device will slip off the cap immediately when force is applied. Therefore, the existing cap screwing device is only suitable for people with large palms and strong hands, and the user experience is poor. For people with small hands and weak hands such as children and the elderly, it is still difficult to use these tools to open the bottle cap. Therefore, it is necessary to design a tool that can easily unscrew bottle caps of various sizes for adults and children, which can easily unscrew the caps of various cans and bottles. SUMMARY

[0028] Figure 1 It is a structure schematic drawing of the cap screwing device of the embodiment of the utility model; Figure 2 It is a structure schematic drawing of the cap screwing device of another embodiment of the utility model.

[0029] Please refer to Figure 1 and Figure 2 The cap screwing device provided by the utility model comprises a fixer 1 and a handle 2, the fixer 1 comprises a clamping portion 12, the handle 2 and the fixer 1 are movably connected, one end of the handle 2 is a gripping portion 21, the other end is an abutting portion 22, the abutting portion 22 and the clamping portion 12 together enclose a space capable of accommodating a bottle cap, and the abutting portion 22 can move relative to the clamping portion 12, and the abutting portion 22 and the clamping portion 12 cooperate to clamp the side surface of the bottle cap.

[0030] Further, the fixer 1 comprises a bottom plate 11, the clamping portion 12 is circumferentially arranged along the edge of the bottom plate 11 and has an opening, and the abutting portion 22 is arranged at the opening. The top surface of the bottle cap is bonded to the bottom plate 11, so that the bottle cap can be better fixed.

[0031] In a specific embodiment, the clamping portion 12 comprises a first clamping portion 121 and a second clamping portion 122, the second clamping portion 122 is higher than the first clamping portion 121, the second clamping portion 122 is provided with a slot 15 near the opening of the bottom plate 11, one end of the handle 2 passes through the slot 15, and the handle 2 is rotatably connected to the fixer 1 at the slot 15, so that the handle 2 can rotate relative to the clamping portion 12 around the rotation shaft.

[0032] Taking the clockwise tightening and counterclockwise loosening of the bottle cap as an example, when the cap opening device is used to open the bottle cap, first, the handle 2 is rotated in the clockwise direction (in the counterclockwise direction in the middle) Figure 1 , the abutting portion 22 is opened, the bottle cap is covered with the fixer 1, the top surface of the bottle cap is attached to the bottom plate 11, and the bottle cap is located in the cavity surrounded by the abutting portion 22 and the fixer 1, then one hand holds the bottle to keep the bottle body still, and the other hand rotates the handle 2 in the counterclockwise direction (in the clockwise direction in the middle) Figure 1 ), the abutting portion 22 and the clamping portion 12 clamp the side surface of the bottle cap, at this time, the friction force generated between the bottle cap and the fixer 1 will keep the fixer 1 still with the bottle cap, so that the clamping effect is achieved, and the bottle cap is tightly locked in the fixer 1, and the handle 2 is continuously controlled in the same direction (counterclockwise direction), so that the cap opening device drives the bottle cap to rotate in the counterclockwise direction, and the bottle cap can be easily unscrewed by using the principle of lever.

[0033] In order to better fix the bottle cap, the abutting portion 22 and the clamping portion 12 are connected through the spring 3; the elastic force of the spring 3 can assist the cap opening device to fix the bottle cap in the cavity formed by the abutting portion 22 and the clamping portion 12, so as to ensure that the bottle cap and the fixer 1 and the handle 2 have at least three point contacts, thereby generating friction. Specifically, the handle 2 is connected with the fixer 1 at the slot 15 through the screw 4, and a lock nut is arranged on the other side of the bottom plate 11 to prevent the screw 4 from falling off, one end of the spring 3 is fixed on the abutting portion 22 of the handle 2 through the knurled nut 5, and the other end is fixed on the clamping portion 12 of the fixer 1 through the knurled nut 5.

[0034] Because the sizes of various bottle caps are different, some bottle caps with certain diameters are difficult to be clamped, therefore, the inner side surface of the clamping portion 12 in contact with the bottle cap is the first attachment surface 13, the first attachment surface 13 is a plane, and the number of the first attachment surface 13 is two or more, preferably three, so that the abutting portion 22 of the handle 2 can ensure that there are at least three contact points when clamping the bottle cap each time, thereby enabling the cap opening device to firmly clamp bottle caps of various sizes.

[0035] Further, in order to prevent the bottle cap from slipping in place, the first attachment surface 13 can be attached with sandpaper or adhesive tape to increase the friction between the bottle cap and the clamping portion 12; or the first attachment surface 13 is formed with a sawtooth pattern, as shown in Figure 2 .

[0036] The capping device provided by this utility model has a second contact surface 23 on the inner surface of the abutment part 22 that contacts the bottle cap. The second contact surface 23 is preferably an arc-shaped surface, which increases the contact area between the abutment part 22 and the bottle cap, thereby increasing the frictional force between the abutment part 22 and the bottle cap. Similarly, serrated patterns, sandpaper, or adhesive strips are formed on the second contact surface 23 to further increase the frictional force between the bottle cap and the abutment part 22.

[0037] The cap-screwing device provided by this utility model has an arc-shaped grip portion 21 with rounded chamfers, which conforms to ergonomics and makes the cap-screwing device more comfortable to hold, allowing people to open various commonly used bottle caps in daily life effortlessly. Furthermore, the grip portion 21 of the handle 2 can also be provided with a hanging hole 24 for hanging and storage. A protrusion 14 is provided on the side of the fixing device 1 near the handle 2, which facilitates one-handed operation. When operating with one hand, one hand can simultaneously grasp the protrusion 14 and the handle 2, causing the abutment portion 22 to open and open the cap-screwing device.

[0038] In other embodiments, if rotating the bottle cap counterclockwise tightens it and rotating it clockwise loosens it, then... Figure 1 and Figure 2 The handle 2 is moved to the left side, so that when the handle 2 is rotated clockwise, the capping device clamps the cap and unscrews it.

[0039] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
