Description

Technical Field

[0001] This utility model relates to the technical field of protective adhesive storage devices, and in particular to a novel integrated device for storing and using protective adhesive. Background Technology

[0002] Protective adhesives are a type of colloidal / paste-like material with physical protection or functional isolation functions. Their core purpose is to form a protective film on the surface of a target object to resist damage from external environmental factors such as corrosion, friction, ultraviolet rays, and pollution, or to isolate different substances from direct contact. Among them, anaerobic adhesives cure rapidly when isolated from oxygen and in contact with metal ions, forming a high-strength, wear-resistant, and corrosion-resistant adhesive layer.

[0003] Traditional anaerobic adhesives need to be poured from sealed bottles or taken with a dropper, during which the adhesive is easily exposed to air. Integrated devices combine "adhesive storage" and "adhesive dispensing," eliminating the need for opening or transferring. Adhesive is dispensed directly by pressing the lever, making it particularly suitable for high-frequency, small-volume continuous use. The core storage requirement for anaerobic adhesives is "air isolation and prevention of impurities." The integrated device's storage chamber is a closed structure, connected to the outside only through the dispensing port, completely preventing the adhesive from contacting air, dust, and oil, thus preventing premature curing or performance degradation. The device uses a linear "lever-piston" push structure to stably control the dispensing volume each time. The lever is integrally molded, non-removable and non-foldable, and to ensure smooth thrust, its length is typically 2-3 times longer than the storage chamber, resulting in a long overall device. Without a locking mechanism, there are many stress points and a large torque; even slight external force can push the piston. If the lever is bumped during workshop handling or squeezed by stacked tools, adhesive will be squeezed out. Furthermore, the overall length of the device occupies storage and packaging space. Therefore, those skilled in the art have provided a novel integrated device for storing and using protective adhesive to solve the problems mentioned in the background art. Utility Model Content

[0004] 1. Technical Solution

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a novel integrated device for storing and using protective adhesive, comprising a cylinder, a feed pipe, a discharge pipe, a pressure rod, and a piston. The feed pipe is connected to one side of the upper end of the cylinder, and the discharge pipe is provided at the lower end of the cylinder. The piston is slidably installed inside the upper end of the cylinder, and a docking seat is provided at the upper end of the piston. The pressure rod is provided on one side of the cylinder, and a docking block is provided at the lower end of the pressure rod. A docking groove is opened inside the upper end of the docking seat for docking and installation with the docking block.

[0007] Furthermore, a retaining sleeve is provided at one end of the cylinder, and the pressure rod is snapped into the inside of the retaining sleeve. A handle is provided at the upper end of the pressure rod.

[0008] Specifically, the ferrule secures the pressure rod, and the handle facilitates the application of compressive force to the pressure rod.

[0009] Furthermore, the feed pipe is provided with a support ring and a valve ring, the valve ring is provided with a valve core, and one end of the valve core is provided with a spring connected to the support ring.

[0010] Specifically, valve core 1 is located inside valve ring 1 via spring 1, closing valve ring 1 so that fluid can only enter in one direction, for use in the input of protective adhesive.

[0011] Furthermore, one end of the valve core is provided with a positioning rod that is slidably installed inside the support ring and the spring, and one end of the feed pipe is provided with a sealing cap, and one end of the sealing cap is provided with a connecting strip that connects to the outer wall of the feed pipe.

[0012] Specifically, when the valve core moves and the spring extends or retracts, it slides inside the support ring via the positioning rod for sliding guidance. The opening of the feed pipe is closed by the sealing cover to prevent the entry of foreign objects. The sealing cover is flexibly connected by the connecting strip.

[0013] Furthermore, the discharge pipe is provided with a second support ring and a second valve ring, the second valve ring is provided with a second valve core, one end of the second valve core is provided with a second spring connected to the second support ring, one end of the discharge pipe is provided with a second sealing cap, and one end of the second sealing cap is provided with a connecting strip connected to the outer wall of the discharge pipe.

[0014] Specifically, valve core two is supported inside valve ring two by spring two, and sealing cover two closes the opening of the discharge pipe to prevent foreign objects from entering, and is flexibly connected by connecting strip.

[0015] Furthermore, a top ring is provided at the upper end of the cylinder, and symmetrically distributed guide rods are provided at the lower end of the top ring. A sliding sleeve is embedded inside the piston and is symmetrically distributed and slidably sleeved on the outer wall of the guide rod. A top cover is provided at the upper end of the cylinder, and a connecting band connected to the cylinder is provided at the upper end of the top cover.

[0016] Specifically, the piston slides on the outer wall of the guide rod via a sliding sleeve, which improves stability. The piston is intercepted by the top ring, and the holes inside the top ring ensure the passage of the docking block and the pressure rod. The top cover prevents the entry of foreign objects from the upper part of the cylinder, and the connecting belt connects the top cover and the cylinder together.

[0017] 2. Beneficial effects

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] This invention stores protective adhesive inside a cylinder. A pre-installed, sliding piston is located inside the cylinder. When the piston presses against the upper part of the cylinder, the protective adhesive flows out through a one-way discharge pipe. The piston and pressure rod are connected and installed together, with the pressure rod located on one side of the cylinder. The pressure rod is separate from the piston during storage. During use, it is connected to the piston. After use, the pressure rod can be removed, avoiding the situation where the pressure rod and piston are integrated inside the cylinder, occupying storage space and preventing accidental leakage of the protective adhesive. The separate piston and pressure rod prevent accidental contact and improve safety.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0034] Example 1

[0035] Please see Figure 1-6 As shown, this embodiment is a novel integrated device for storing and using protective adhesive, including a cylinder 1, a feed pipe 2, a discharge pipe 3, a pressure rod 6, and a piston 11. The feed pipe 2 is connected to one side of the upper end of the cylinder 1, and the discharge pipe 3 is provided at the lower end of the cylinder 1. The piston 11 is slidably installed inside the upper end of the cylinder 1, and a docking seat 12 is provided at the upper end of the piston 11. The pressure rod 6 is provided on one side of the cylinder 1, and a docking block 9 is provided at the lower end of the pressure rod 6. A docking groove 14 is opened inside the upper end of the docking seat 12 to dock with the docking block 9.

[0036] One end of the cylinder 1 is provided with a sleeve 7, and the pressure rod 6 is snapped into the sleeve 7. The upper end of the pressure rod 6 is provided with a handle 8.

[0037] The feed pipe 2 is equipped with a support ring 17 and a valve ring 18. The valve ring 18 is equipped with a valve core 21. One end of the valve core 21 is equipped with a spring 22 that is connected to the support ring 17.

[0038] One end of the valve core 21 is provided with a positioning rod 16 that is slidably installed inside the support ring 17 and the spring 22. One end of the feed pipe 2 is provided with a sealing cover 20, and one end of the sealing cover 20 is provided with a connecting strip 19 that is connected to the outer wall of the feed pipe 2.

[0039] The discharge pipe 3 is equipped with a second support ring 26 and a second valve ring 24. The second valve ring 24 is equipped with a second valve core 25. One end of the second valve core 25 is equipped with a second spring 23 connected to the second support ring 26. One end of the discharge pipe 3 is equipped with a second sealing cover 27. One end of the second sealing cover 27 is equipped with a connecting strip 19 connected to the outer wall of the discharge pipe 3.

[0040] A top ring 13 is provided at the upper end of the cylinder 1, and symmetrically distributed guide rods 10 are provided at the lower end of the top ring 13. A sliding sleeve 15, which is symmetrically distributed and slidably sleeved on the outer wall of the guide rod 10, is embedded inside the piston 11. A top cover 4 is provided at the upper end of the cylinder 1, and a connecting band 5 connected to the cylinder 1 is provided at the upper end of the top cover 4.

[0041] In this embodiment, the anaerobic adhesive of model LOCTITE243, with a viscosity of 200-500 cP and an applicable temperature range of -50 to 150°C, is used for storage and use. The cylinder 1 is 18cm high, 5cm in inner diameter, and has a capacity of approximately 350mL. The feed pipe 2 is 6cm long and 1.5cm in inner diameter, the discharge pipe 3 is 8cm long and 0.8cm in inner diameter, and the pressure rod 6 is 25cm long. The overall design is suitable for bolt-locking scenarios in workshops. During use, the top cover 4 (made of food-grade PP plastic) is opened at the top of the cylinder 1 to seal the opening and prevent dust and moisture from entering. The connecting strap 5 is made of nylon to prevent the top cover 4 from being lost. The anaerobic adhesive is injected into the cylinder 1 through the feed pipe 2. The valve core... Valve core 21, made of nitrile rubber, works with spring 22 to achieve a one-way seal, preventing backflow of the adhesive. Under the pressure of the adhesive, valve core 21 compresses spring 22, which is made of 304 stainless steel, providing a reset force and pushing valve core 21 to close valve ring 18. Valve core 21 moves along positioning rod 16 towards support ring 17. Positioning rod 16, made of 45 steel, guides valve core 21 to slide, preventing valve core displacement and sealing failure. Support ring 17, made of HDPE plastic, fixes spring 22 and limits the maximum displacement of valve core 21. Valve ring 18 opens. Valve ring 18, made of wear-resistant ABS plastic, cooperates with valve core 21 to form a sealing surface, controlling the opening and closing of the fluid channel, allowing the adhesive to smoothly enter the interior of cylinder 1.

[0042] After the adhesive injection is completed, spring 22 resets and pushes valve core 21 to close valve ring 18, and then the sealing cap 20 of feed pipe 2 is put on. The sealing cap 20 is made of silicone rubber and seals the port of feed pipe 2 to prevent foreign objects from entering. Connecting strip 19 is made of elastic rubber to prevent the sealing cap 20 from being lost. The adhesive pre-filling is completed. Piston 11 is installed. Piston 11 is made of modified PTFE plastic and slides inside cylinder 1 to squeeze the adhesive to achieve dispensing. It does not chemically react with anaerobic adhesive. Sleeve 15 is made of wear-resistant nylon to reduce piston wear. The friction between piston 11 and guide rod 10 ensures smooth sliding of piston 11. Align the sliding sleeve 15 on piston 11 with the guide rod 10 at the lower end of top ring 13. Top ring 13 is made of aluminum alloy and its function is to fix guide rod 10 and intercept piston 11, limiting the maximum upward displacement of piston 11. Guide rod 10 is made of 304 stainless steel and guides piston 11 to slide in a straight line to prevent piston 11 from tilting and causing glue residue or leakage. Slowly fit the outer wall of guide rod 10 to ensure that piston 11 is tightly fitted with inner wall of cylinder 1, and then cover with top cover 4.

[0043] Remove the pressure rod 6, made of 6061 aluminum alloy, which transmits extrusion pressure and pushes the piston 11 downward. The integrated structure of the device ensures structural strength. Align the lower end of the connecting block 9 with the connecting groove 14 in the upper connecting seat 12 of the piston 11, and insert it to complete the assembly of the pressure rod 6 and piston 11. The connecting block 9, made of ABS plastic, cooperates with the connecting groove 14 to achieve quick connection between the pressure rod 6 and piston 11. The connecting seat 12, made of HDPE plastic, connects the piston 11 and pressure rod 6, transmitting the extrusion pressure of the pressure rod 6. Remove the sealing cap 27 of the discharge pipe 3, made of silicone rubber, to seal the port of the discharge pipe 3, preventing the adhesive from solidifying and clogging or foreign objects from entering. Hold the handle 8 at the upper end of the pressure rod 6, made of non-slip TPE rubber, to increase hand friction, facilitate pressure application, and improve operating comfort. Apply downward pressure to the pressure rod 6. The piston 11... Under the action of thrust, it slides downward along the guide rod 10, squeezing the anaerobic adhesive in the cylinder 1. The valve core 25 is made of nitrile rubber and works with the spring 23 to achieve a one-way seal, controlling the flow of adhesive. The pressure of the adhesive pushes the valve core 25 in the discharge pipe 3 to compress the spring 23. The spring 23 is made of 304 stainless steel and provides a reset force, pushing the valve core 25 to close the valve ring 24 and move along the direction of the support ring 26. The support ring 26 is made of HDPE plastic and fixes the spring 23, limiting the maximum displacement of the valve core 25. The valve ring 24 opens. The valve ring 24 is made of wear-resistant ABS plastic and works with the valve core 25 to form a sealing surface, controlling the opening and closing of the adhesive flow channel. The adhesive flows out from the port of the discharge pipe 3, and bolt locking and other operations are completed as needed. After the force is stopped, the spring 23 resets and pushes the valve core 25 to close the valve ring 24, preventing air from flowing back into the cylinder 1.

[0044] After use, pull out the pressure rod 6 and insert it into the sleeve 7 on one side of the cylinder 1. The sleeve 7 is made of elastic PP plastic and fixes the pressure rod 6 in the idle state to prevent damage or accidental contact caused by random placement of the pressure rod 6. This achieves separate storage of the pressure rod 6 and the piston 11. Cover the sealing cap 27 of the discharge pipe 3 and the top cover 4 of the cylinder 1, and place the device in a dry environment away from light at 10-25℃ to complete the storage. In this embodiment, the separate pressure rod 6 and piston 11 design solves the problems of large space occupation and easy accidental contact of the traditional integrated pressure rod 6. When idle, the pressure rod 6 is inserted into the sleeve 7, and the overall length of the device is shortened from the long specification of the cylinder 1 plus the pressure rod 6 to the short specification, saving storage space. After the pressure rod 6 is separated from the piston 11, no external force directly acts on the piston 11, reducing the risk of glue squeezing out due to accidental contact. At the same time, the one-way valve structure of the feed pipe 2 and the discharge pipe 3 ensures that the cylinder 1 is completely sealed, meeting the needs of high-frequency, small-dose continuous use in the workshop.
