Description

Technical Field

[0001] This utility model relates to the field of glass adhesive technology, and in particular to a glass adhesive shell with an adjustable dispensing head structure. Background Technology

[0002] Glass glue is an adhesive made primarily of sodium silicate, with added acetic acid and silicone materials. It cures at room temperature without additional heating, becoming an elastic, rubbery substance with excellent adhesion and sealing properties. Widely used for bonding and sealing glass with other materials such as metal, plastic, and stone, it plays a vital role in building decoration and home repair, effectively preventing gas and liquid leakage. It also possesses certain resistance to high and low temperatures and aging. The outer casing of the glass glue container is used to hold and protect the glue, primarily serving to store the glue, control dispensing, and facilitate use.

[0003] Existing glass glue shells are usually made of materials such as plastic, and different structures are designed according to usage requirements. The main container is mostly a cylindrical plastic bottle made of HDPE or PP material, which has chemical resistance to adapt to silicone glue components. The inner wall of the bottle is smoothed to prevent glue from sticking and reduce waste.

[0004] In the use of existing glass glue casings, the glue outlet at the end of the casing is usually of a fixed size. Due to the deep gaps in some areas, the glass glue may not be able to fill the gaps completely, thus affecting the compatibility and quality of the glue application. Utility Model Content

[0005] To address the issue that existing glass glue casings typically have a fixed-size outlet at the end, which can cause gaps in some areas to be difficult to fill completely, thus affecting the glue's compatibility and quality, the following measures are needed.

[0006] The technical solution of this utility model is as follows: a glass glue shell with a dispensing head adjustment structure, including a cylindrical body, a connecting cap threaded to the end of the cylindrical body, a first conduit inserted in the middle of the connecting cap, a second conduit inserted in the middle of the first conduit, an injection head rotatably connected to the end of the second conduit, a second interface fixedly provided at the end of the first conduit near the end of the second conduit, a plurality of first slots opened on the side wall of the second interface, a limit clamp threaded to the outer surface of the second interface, and two first slots opened at the end of the second conduit, each of the first slots being secured with a first sealing ring.

[0007] Furthermore, a first connector is fixed at the end of the cylinder, and the first connector is connected to the inside of the cylinder. The connecting cover is threaded onto the outer surface of the first connector, which improves the stability of the connecting cover installation.

[0008] Furthermore, a washer is snapped into the inner top of the connecting cover, and several first anti-slip grooves are provided on the side wall of the connecting cover, which improves the convenience of rotating the connecting cover.

[0009] Furthermore, the connecting cover, the first conduit, and the second interface are fixedly connected to form an integrated structure. The first slots are symmetrically distributed, and several second anti-slip grooves are provided on the side wall of the limiting hoop, which improves the convenience of rotating the limiting hoop.

[0010] Furthermore, a limiting block is fixed at the bottom of the second catheter, and a second groove is opened at the top of the injection head. The limiting block is rotatably connected in the middle of the second groove, which improves the stability of the injection head rotation.

[0011] Furthermore, a first through groove is provided at the bottom of the limiting block, and a second through groove is provided in the middle of the injection head near the second groove opening, which improves the sealing performance of the connection between the second conduit and the injection head.

[0012] Furthermore, a second slot is provided on the side wall of the limiting block, and a second sealing ring is engaged in the middle of the second slot, which improves the convenience of adjusting the size of the glue outlet.

[0013] Furthermore, a threaded hole is provided on the side wall of the injection head, and a limit plug is connected to the middle thread of the threaded hole. The end of the limit plug passes through the threaded hole and is supported on the side wall of the second sealing ring, which improves the stability of the injection head support.

[0014] The beneficial effects of this utility model are: Compared to traditional glass glue casings, this design improves the ease of adjusting the injection head distance through the combination of a connecting cap, a first guide tube, a second guide tube, an injection head, and a limiting clamp. It also enhances the stability of the second guide tube clamping by combining the limiting clamp, a second interface, and a first groove. Furthermore, it improves the stability of the connection between the second guide tube and the injection head by combining the first slot and a first sealing ring. This expands the glue injection range and improves the adaptability and quality of the glue injection. Additionally, the combination of a limiting block, a first through slot, a second groove, and a second through slot further enhances the ease of adjusting the injection head's injection diameter, thus facilitating control of the glass glue flow rate.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Among the currently discovered feasible technologies, the following are described: The outer shell of the glass adhesive serves as the carrier and control center of the adhesive. Its structural design revolves around three core objectives: "efficient storage, precise adhesive control, and convenient operation." The components work together to ensure the stability of the glass adhesive and improve the ease of construction.

[0019] The main container is the core load-bearing component of the outer shell, responsible for storing the silicone sealant. The design of the main container must balance chemical stability and structural strength. Material characteristics: It is generally made of high-density polyethylene (HDPE) or polypropylene (PP). These two materials have excellent chemical corrosion resistance and can resist the erosion of acidic or neutral components in silicone sealant, avoiding long-term contact that could cause the bottle to crack or swell. At the same time, the material has moderate flexibility, which makes it easy to apply pressure to extrude the adhesive while maintaining shape stability. Structural form: Mostly cylindrical bottles with high-precision polished inner walls, achieving a surface roughness of ≤0.8μm. This reduces the adhesion between the silicone sealant and the bottle wall, ensuring smooth extrusion of the adhesive. The bottle thickness is gradient along the axial direction, increasing to 1.5-2mm at the bottle mouth and bottom (approximately 1mm in the middle) to enhance the pressure resistance of key areas and prevent deformation during extrusion.

[0020] Basic dispensing nozzle design: The front end of the bottle mouth extends into a conical dispensing nozzle, and the tip diameter can be preset according to needs (1-3mm) to facilitate deep application of glue into gaps.

[0021] Silicone sealant is prone to curing upon contact with air. The sealing system needs to block the exchange of gas and moisture between the sealant and the outside environment to extend its shelf life. Multi-stage sealing design: The end of the dispensing nozzle is equipped with a screw-type sealing cap with a silicone sealing gasket (Shore hardness 60-70) embedded inside. When tightened, the sealing gasket fits tightly against the tip of the dispensing nozzle to achieve the first seal. Polytetrafluoroethylene grease is applied to the threaded connection between the adjusting sleeve and the dispensing nozzle to reduce friction and form a second barrier to prevent air from seeping in through the thread gaps.

[0022] Please refer to Figures 1-5 A glass glue casing with an adjustable dispensing head includes a cylindrical body 1 made of HDPE material, which is chemically resistant. The inner wall of the bottle is smoothed to prevent glass glue adhesion and reduce waste. A connecting cap 2 is threaded to the end of the cylindrical body 1. A first connector 8 is fixed to the end of the cylindrical body 1, and the first connector 8 is connected to the inside of the cylindrical body 1 to facilitate filling the inside of the cylindrical body 1 with glass glue. The operator can connect the connecting cap 2 and the first connector 8 by rotating the connecting cap 2 counterclockwise. The external dimensions of the first connector 8 are adapted to the internal dimensions of the connecting cap 2. The connecting cap 2 is threaded to the outer surface of the first connector 8, which improves the installation stability of the connecting cap 2. A first conduit 3 is inserted into the middle of the connecting cap 2. The first conduit 3 is annular and made of rubber, which improves the sealing of the connecting cap 2. A second conduit 4 is inserted into the middle of the first conduit 3. The external dimensions of the second conduit 4 are adapted to the internal dimensions of the first conduit 3, which improves the insertion stability of the second conduit 4. The end of the second conduit 4 is rotatably connected to... An injection head 5 is provided for discharging glass glue. A second interface 9 is fixed at the end of the first conduit 3 near the second conduit 4. Several first slots 10 are opened on the side wall of the second interface 9, and the four first slots 10 are symmetrically distributed. A limit clamp 6 is threadedly connected to the outer surface of the second interface 9. When the operator rotates the limit clamp 6 counterclockwise, the limit clamp 6 can be moved along the middle of the second interface 9, thereby clamping the second interface 9 and increasing the friction force of the second conduit 4 inserted into the second interface 9. Two first slots 14 are opened at the end of the second conduit 4. A first sealing ring 15 is clamped in the middle of each first slot 14. The first sealing ring 15 is made of rubber, which improves the sealing performance of the connection between the first conduit 3 and the second conduit 4. When the operator rotates the limit clamp 6 clockwise, the friction force of the second conduit 4 inserted into the second interface 9 can be loosened, thereby facilitating the sliding of the second conduit 4 to adjust the length of the injection head 5 from the cylinder 1, thereby expanding the glue injection range and improving the adaptability and quality of glue injection.

[0023] A washer 22 is snapped into the inner top of the connecting cover 2. Several first anti-slip grooves 20 are provided on the side wall of the connecting cover 2 to increase frictional resistance and improve the convenience of rotating the connecting cover 2. The connecting cover 2, the first conduit 3 and the second interface 9 are fixedly connected to form an integral structure. Several second anti-slip grooves 21 are provided on the side wall of the limiting clamp 6 to increase frictional resistance and improve the convenience of rotating the limiting clamp 6.

[0024] The bottom end of the second conduit 4 is fixed with a limiting block 11 to form an integral structure. The top end of the injection head 5 is provided with a second groove 18. The limiting block 11 is rotatably connected in the middle of the second groove 18, which improves the stability of the rotation of the injection head 5. The bottom end of the limiting block 11 is provided with a first through groove 12. The middle of the injection head 5 near the second groove 18 is provided with a second through groove 19, which improves the sealing of the connection between the second conduit 4 and the injection head 5.

[0025] A second slot 16 is provided on the side wall of the limiting block 11. A second sealing ring 17 is engaged in the middle of the second slot 16. The second sealing ring 17 is made of rubber, which improves the sealing performance of the connection between the second conduit 4 and the injection head 5. Rotating the injection head 5 can adjust the angle between the first through groove 12 and the second through groove 19, thereby adjusting the size of the glass glue outlet and improving the convenience of adjusting the size of the glue outlet. This makes it easier to control the flow rate and speed of the glass glue injection. A threaded hole 13 is provided on the side wall of the injection head 5. A limiting bolt 7 is threadedly connected in the middle of the threaded hole 13. The end of the limiting bolt 7 passes through the threaded hole 13 and is supported on the side wall of the second sealing ring 17, which improves the stability of the injection head 5 support.

[0026] When using this glass glue casing, the operator first fills the inside of the cylinder 1 with glass glue from the first connector 8, and then threads the connecting cap 2 onto the outer surface of the first connector 8. When glue injection is needed, the operator holds the cylinder 1 and inserts the injection head 5 into the designated position, and then squeezes the cylinder 1, so that the glass glue is discharged sequentially through the first connector 8, connecting cap 2, first conduit 3, second conduit 4 and injection head 5. When the size injected by the injection head 5 is insufficient, the operator rotates the limiting clamp 6 clockwise to release the limiting clamp 6 from the second interface 9, so as to facilitate the sliding adjustment of the length of the second conduit 4 extending into the first conduit 3. Then, rotating the limiting clamp 6 counterclockwise can drive the limiting clamp 6 to move along the middle of the second interface 9, thereby clamping the second interface 9, thereby increasing the friction of the second conduit 4 inserted into the second interface 9, thereby improving the stability of the connection between the second conduit 4 and the first conduit 3, thereby expanding the glue injection range and improving the adaptability and quality of glue injection.

[0027] Furthermore, considering that the fixed size of the injection head 5 affects the injection speed and flow rate of the glass glue, the combination of the limiting block 11, the first through groove 12, the second groove 18 and the second through groove 19 improves the convenience of adjusting the injection diameter of the injection head 5, thereby facilitating the control of the glass glue flow rate.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
