[0002] Battery shells are usually made of plastic and are processed using injection molding technology. This type of battery shell is light, thin, strong and durable. During the injection molding process, nuts need to be placed in the injection mold in advance so that the nuts and the battery shell are injected into one. They are used to fix the components inside the battery and enhance the stability and safety of the structure.

[0003] The built-in metal nut is connected to the internal components of the battery through screws, thereby tightly connecting the component to the battery shell. The nut needs to ensure that the internal components of the battery will not loosen or fall off during use.

[0004] In the prior art, a T-nut is generally installed inside the battery shell. The screw head of the T-nut in the prior art is located at one end of the nut as a whole, such as an anti-falling T-nut with publication number CN216044914U. However, this setting is easy to accidentally touch the screw head part and cause the nut to rotate as a whole, and then loosen and fall off. Utility Model Content

[0005] To this end, an embodiment of the present invention provides a T-cap nut to solve the problem in the prior art that the nut is easily loosened and falls off due to the screw head being located at one end of the nut.

[0007] The outer end of the hexagonal ring protrudes from the outer surface of the sleeve, the hexagonal ring is located in the middle part of the nut body, and the center part of the inner core is provided with a threaded hole, and the threaded hole passes through the inner core;

[0008] A plurality of inlay grooves are provided on the inner wall of the sleeve, a plurality of strip-shaped protrusions are fixedly provided on the outer end of the inner core, elastic rubber strips are fixedly provided on both sides of the strip-shaped protrusions, the strip-shaped protrusions correspond to the inlay grooves one by one and are embedded in the corresponding inlay grooves, and the rubber strips are fixedly connected to the inner walls of the corresponding inlay grooves.

[0009] Furthermore, a guide ring is provided at the top of the inner core, and the guide ring is located at the opening of the top of the threaded hole. The guide ring is funnel-shaped, and the inner part of the guide ring becomes more concave as it approaches the threaded hole.

[0010] Furthermore, two annular grooves are provided at the outer end of the sleeve, and the annular grooves are located at the bottom of the hexagonal ring, which can increase the contact area between the battery shell and the nut body during injection molding, thereby increasing the connection strength.

[0011] Furthermore, a plurality of point-shaped protrusions are fixedly provided on the inner wall of the annular groove, so that the inner wall of the annular groove is rough, thereby effectively preventing the nut from rotating.

[0012] Furthermore, a buffer washer is provided on the top of the nut body when connected to the screw, the buffer washer comprises an elastic rubber ring, and a plurality of rubber protrusions are fixedly provided on the bottom end of the rubber protrusion;

[0013] The top of the sleeve is provided with a plurality of embedding holes, and the rubber protrusions correspond to the embedding holes one by one and are embedded in the corresponding embedding holes.

[0031] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0032] like Figure 1-8 As shown, the utility model provides a T-cap nut, comprising a nut body 1, the nut body 1 comprising a sleeve 101 and an inner core 102, the sleeve 101 being sleeved on the outer end of the inner core 102, the outer end of the inner core 102 being in contact with the inner wall of the sleeve 101, and a hexagonal ring 2 being fixed to the outer end of the sleeve 101;

[0033] The outer end of the hexagonal ring 2 protrudes from the outer surface of the sleeve 101. The hexagonal ring 2 is located in the middle of the nut body 1. A threaded hole 103 is opened in the center of the inner core 102. The threaded hole 103 passes through the inner core 102.

[0034] A plurality of inlay grooves 104 are provided on the inner wall of the sleeve 101, and a plurality of strip-shaped protrusions 105 are fixedly provided on the outer end of the inner core 102. Elastic rubber strips 106 are fixedly provided on both sides of the strip-shaped protrusions 105. The strip-shaped protrusions 105 correspond to the inlay grooves 104 one by one and are embedded in the corresponding inlay grooves 104. The rubber strips 106 are fixedly connected to the inner walls of the corresponding inlay grooves 104.

[0035] The main body of the nut consists of a nut body 1 and a hexagonal ring 2. The hexagonal ring 2 is arranged at the outer end of the nut body 1 and protrudes from the outer surface of the nut body 1. Unlike traditional nuts, the hexagonal ring 2 is located in the middle of the nut body 1, rather than at one end of the nut body 1. When the nut is injection-molded into the interior of the battery shell, since the hexagonal ring 2 is located in the middle of the nut body 1, the nut is not easy to rotate, loosen or fall off, and the connection of battery components using this nut will be more secure.

[0036] The nut body 1 of the nut is mainly composed of a sleeve 101 and an inner core 102. When making the nut, the sleeve 101 is put on the outer end of the inner core 102, and the strip protrusion 105 is embedded in the inlay groove 104. At this time, there is a gap between the two sides of the strip protrusion 105 and the inner wall of the inlay groove 104. The molten rubber is injected into the gap, and a rubber strip 106 is formed after cooling and solidification. The rubber strip 106 connects the inlay groove 104 and the strip protrusion 105, and then connects the sleeve 101 and the inner core 102. When the screw is installed in the threaded hole 103 of the nut, the inner core 102 will be subjected to the force of the screw and has a tendency to rotate. At this time, the elastic rubber strip 106 can play a buffering role between the inner core 102 and the sleeve 101, preventing the force from affecting the sleeve 101 and causing the nut to loosen or fall off.

[0037] A guide ring 4 is provided at the top of the inner core 102 . The guide ring 4 is located at the opening at the top of the threaded hole 103 . The guide ring 4 is funnel-shaped, and the closer the inside of the guide ring 4 is to the threaded hole 103 , the more concave it becomes.

[0038] When installing the screw, when one end of the screw approaches the threaded hole 103 , the funnel-shaped guide ring 4 can play a guiding role, guiding the one end of the screw into the threaded hole 103 .

[0039] The nut needs to be injection molded and connected to the battery shell. In order to improve the connection strength with the battery shell, such as Figure 1 As shown, two annular grooves 3 are provided at the outer end of the sleeve 101. The annular grooves 3 are located at the bottom of the hexagonal ring 2. During injection molding, the contact area between the battery shell and the nut body 1 can be increased, thereby increasing the connection strength.

[0040] A plurality of dot-shaped protrusions 6 are fixedly provided on the inner wall of the annular groove 3 , making the inner wall of the annular groove 3 rough, thereby effectively preventing the nut from rotating.

[0041] During injection molding, the softened plastic will flow into the annular groove 3. After solidification, a part of the battery shell will be embedded in the annular groove 3 at the outer end of the nut body 1, thereby increasing the contact area between the battery shell and the nut body 1. At the same time, the dot-shaped protrusions 6 also make the inner wall of the annular groove 3 uneven, further increasing the contact area while increasing the friction between the nut body 1 and the battery shell, preventing the nut body 1 from rotating, and thus preventing the nut body 1 from loosening or falling off.

[0042] When the screw is connected through the nut body 1 to install the battery component, as shown in FIG. Figure 4 、 5 As shown, a buffer washer 7 is provided on the top of the nut body 1 when connected to the screw. The buffer washer 7 includes an elastic rubber ring 701 , and a plurality of rubber protrusions 702 are fixed on the bottom end of the rubber protrusion 702 ;

[0043] The top of the sleeve 101 is provided with a plurality of embedding holes 5 , and the rubber protrusions 702 correspond to the embedding holes 5 one by one and are embedded in the corresponding embedding holes 5 . The buffer washer 7 is fixed to the top of the nut body 1 through the rubber protrusions 702 , thereby providing buffering protection for the nut body 1 .

[0044] The screw or battery components are tightly fixed on the nut, so a buffer washer 7 is set at the top of the nut. The elasticity of the buffer washer 7 plays a buffering role to prevent the screw or battery component from applying excessive force to the nut body 1 and causing the nut body 1 to be squeezed and damaged.

[0045] When the nut is not injection molded onto the battery case, the nut needs to be protected, such as Figure 6 、 7 As shown, the outer end of the nut body 1 is provided with two protective sleeves 8 before injection molding. The two protective sleeves 8 are respectively located at the top and bottom of the hexagonal ring 2 to protect the nut body 1.

[0046] The protective sleeve 8 includes an elastic mounting ring 801 sleeved on the outer end of the sleeve 101, and a sponge sleeve 802 is fixedly provided on the outer end of the elastic mounting ring 801. The diameter of the sponge sleeve 802 is larger than the outer diameter of the hexagonal ring 2. Therefore, after the nut is laid down as a whole, the sponge sleeve 802 can play a supporting role, so that the outer end of the hexagonal ring 2 does not contact the ground or the table. A plurality of anti-roll protrusions 803 are fixedly provided on the outer end of the sponge sleeve 802.

[0047] When the nut is not injection molded onto the battery shell, a protective sleeve 8 is set at the top and bottom of the hexagonal ring 2. The sponge sleeve 802 can play a supporting role. Since its outer diameter is larger than the outer diameter of the hexagonal ring 2, it can play a supporting role to prevent the outer ends of the nut body 1 and the hexagonal ring 2 from contacting the desktop or the ground and being worn. The protective sleeve 8 can be removed from the outer end of the nut body 1 before injection molding, and the protective sleeve 8 can also be reused.

[0048] In order to prevent dust from entering the threaded hole 103, Figure 6 、 8 As shown, both ends of the nut body 1 are provided with dustproof stickers 9 before injection molding. The dustproof stickers 9 include a canvas piece 901. A rubber piece 902 is fixedly provided on the side of the canvas piece 901 facing the nut body 1. An adhesive layer 903 is fixedly provided on the side of the rubber piece 902 facing the nut body 1 and adhered to the nut body 1 through the adhesive layer 903.

[0049] The canvas piece 901 and the rubber piece 902 have the same size, and the size of the canvas piece 901 and the rubber piece 902 is larger than the size of the adhesive layer 903. When injection molding is required, the dustproof sticker 9 is torn off from the nut body 1 as a whole. The dustproof sticker 9 can play a dust-proof role before use. The size of the canvas piece 901 and the rubber piece 902 is larger than the adhesive layer 903 to facilitate the removal of the dustproof sticker 9.

[0050] When the nut is not injection molded onto the battery shell, the dustproof sticker 9 is adhered to both ends of the nut body 1 through the adhesive layer 903, so as to seal both ends of the nut body 1, and moisture and dust cannot enter the threaded hole 103, thereby preventing dust from affecting the use of the threaded hole 103.

[0051] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
