A kind of shed rivet hole glue injection device

Abstract

This invention relates to a glue injection device for rivet holes in container houses, belonging to the field of glue injection tools. The device includes a primary sleeve and a secondary sleeve coaxially connected. A glue storage tube is axially movable within the cavities of the primary and secondary sleeves. A spring is installed in the secondary sleeve to achieve elastic reset of the glue storage tube. A knob rod and a threaded rod form a screw extrusion assembly for pushing the glue storage tube axially and quantitatively extruding the glue within the tube. A guide post is provided at the end of the secondary sleeve, and a glue outlet at the end of the glue storage tube is inserted into the guide post. Multiple glue holes are evenly distributed around the outlet. By inserting the guide post into the rivet hole, the knob rod pushes the glue storage tube axially to allow the glue holes to enter the interior of the rectangular steel beam. Rotating the knob rod causes the threaded rod to move axially to extrude the glue, thus coating the glue around the rivet hole on the inner wall of the rectangular steel beam. This invention solves the problem of existing container house rivet hole glue injection methods failing to apply glue to the contact surface between the rivet and the inner wall of the rectangular steel beam.

Description

Technical Field

[0001] This invention relates to the field of adhesive injection tools, and more specifically to an adhesive injection device for rivet holes in modular shelters. Background Technology

[0002] As a versatile loading platform, the modular container plays a vital role. Corner components, essential for ensuring the overall strength of the container, are indispensable for connecting the main panels. Currently, the assembly methods for corner components and main panels are as follows: Figure 1 The riveting process shown involves drilling rivet holes in the angular component, with the rivet holes penetrating the connecting edge between the angular component and the rectangular steel beam in the bulkhead. The angular component is then riveted and secured to the rectangular steel beam and skin of the bulkhead (the skin is sandwiched between the rectangular steel beam and the angular component). During riveting, a seal is required at the rivet joint to ensure the airtightness and watertightness of the hull.

[0003] Current methods for sealing rivet joints typically involve applying sealant to the rivet or rivet hole, with the aim of achieving a sealant that prevents damage to the joint. Figure 1 The colloid sealant is applied at position 10, which is the contact surface between the rivet and the inner wall of the rectangular steel beam. Testing revealed that the sealant is only effective at this location. Figure 1 Apply the adhesive evenly to the indicated sealing area to ensure optimal airtightness and watertightness of the cabin.

[0004] Existing methods of applying sealant to rivets or rivet holes all have certain drawbacks: The main problems with applying sealant directly to rivets are: 1. Difficulty in applying it evenly to the rivet; 2. Uncontrollable application amount; 3. Risk of sealant being scraped outside the hole during rivet insertion; 4. Difficulty in achieving the desired sealant application depth. Figure 1 The colloidal seal position shown is not effectively sealed and is at risk of failure.

[0005] The main problems with injecting adhesive into rivet holes are: 1. When injecting adhesive from outside the rivet holes of angular parts, the adhesive is easy to drip into the steel beams of the container and cannot effectively adhere to the area around the rivet holes; 2. The amount of adhesive used is uncontrollable because it is around the outside of the hole; 3. It contaminates the outer surface of the container.

[0006] Based on the above analysis, the current method of applying adhesive to seal the corner components and large panels of the modular shelter carries the risk of sealing failure. Therefore, it is necessary to provide a device for injecting adhesive into the rivet holes of the modular shelter to solve the above problems. Summary of the Invention

[0007] The technical problem to be solved: To avoid the shortcomings of existing technologies, this invention provides a device for injecting adhesive into the rivet holes of a container house. This device can controllably and evenly apply adhesive directly to the contact surface between the rivet and the inner wall of the rectangular steel beam, ensuring the container house's airtightness and solving the problems existing in the current adhesive application method.

[0008] The technical solution of this invention is: a device for injecting adhesive into rivet holes in a modular shelter, comprising: The first-stage sleeve is a hollow cylinder with open ends, and one end of its inner wall has internal threads. The secondary sleeve is coaxially installed on the internal thread end of the primary sleeve, and its inner cavity is connected to the inner cavity of the primary sleeve. The end of the secondary sleeve away from the primary sleeve is coaxially provided with a hollow guide post that passes through its inner cavity. The inner cavity of the secondary sleeve is provided with an axial limiting platform. The glue storage tube is axially movable and installed in the inner cavity of the first-stage and second-stage sleeves for storing glue. The outer diameter wall of the glue storage tube located in the second-stage sleeve is provided with a retaining ring. The retaining ring and the limiting platform form an axial limit to prevent the glue storage tube from falling out. The end of the glue storage tube is provided with a columnar glue outlet head, which is inserted into the guide column. Multiple glue holes are evenly distributed around the glue outlet head for dispensing glue. The spring is installed inside the secondary sleeve and fitted onto the outer diameter of the glue storage tube. One end of the spring contacts the retaining ring of the glue storage tube, and the other end contacts the inner wall of the secondary sleeve. It is used for elastic reset after the glue storage tube moves axially and dispenses glue. And the screw extrusion assembly, which is installed at the end of the primary sleeve away from the secondary sleeve, is used to push the glue storage tube to move axially toward the guide column and to quantitatively extrude the glue in the glue storage tube; The guide post is inserted into the rivet hole. The glue storage tube is pushed axially by the screw extrusion assembly so that the glue outlet of the glue head enters the interior of the rectangular steel beam. The glue is then extruded by the extrusion assembly to coat the glue around the rivet hole on the inner wall of the rectangular steel beam.

[0009] A further technical solution of the present invention is: the screw extrusion assembly includes a knob rod and a threaded rod; The knob lever includes a chuck and operating levers symmetrically mounted on both sides of the chuck. The lower end of the chuck covers the open end of the first-stage sleeve away from the second-stage sleeve. The lower end face of the chuck is used to axially push the glue storage tube, and the outer diameter of the lower end of the chuck forms a circumferential limit with the first-stage sleeve. The center of the chuck is provided with a threaded hole for threading a threaded rod. The operating lever is used for hand operation of the knob lever. The threaded rod includes a screw body and an extrusion disc. The screw body is vertically inserted into the threaded hole of the chuck, and the two are threaded together. One end of the screw body extends into the glue storage tube, and the extrusion disc is provided at this end. The extrusion disc is used to extrude glue. The threaded rod is driven to move axially by rotating the knob to extrude glue in a metered manner.

[0010] A further technical solution of the present invention is: a scale is provided around the threaded hole on the upper end face of the chuck, and the scale division value is 10°; a pointer is provided at the end of the screw body away from the extrusion plate, and the pointer is used to cooperate with the scale to indicate the turning angle of the knob rod.

[0011] A further technical solution of the present invention is as follows: the outer diameter of the lower end of the chuck matches the inner diameter of the first-stage sleeve, and the lower end face of the chuck contacts the end of the glue storage tube away from the glue outlet; when the chuck pushes the glue storage tube to move axially, the lower end of the chuck is embedded in the first-stage sleeve, and the operating rods on both sides of the chuck contact the end face of the first-stage sleeve to form a limit; the depth to which the lower end of the chuck is embedded in the first-stage sleeve must ensure the working depth of the glue outlet when the glue hole of the glue outlet enters the rectangular steel beam to dispense glue.

[0012] A further technical solution of the present invention is: the tube body of the glue storage tube is a cylindrical structure with an outer diameter that matches the inner diameter of the first-stage sleeve, and its inner cavity forms a glue storage chamber; the columnar glue outlet head is a hollow cylindrical structure, its inner cavity is connected to the glue storage chamber, the end of the glue outlet head is closed, and multiple glue holes are evenly distributed on the circumference of the cylindrical wall of the glue outlet head.

[0013] A further technical solution of the present invention is: the plurality of glue holes are four in number, and the glue holes are inclined holes with their inclination direction facing the body of the glue storage tube.

[0014] A further technical solution of the present invention is that the material of the glue storage tube is polytetrafluoroethylene.

[0015] A further technical solution of the present invention is: the secondary sleeve is a split structure with two halves along its axis, which are joined together to form a secondary sleeve; the outer diameter of the guide post is adapted to the rivet hole.

[0016] The beneficial effects of this invention are as follows: This invention provides a container rivet hole adhesive injection device. An adhesive storage tube is axially movably installed within the inner cavities of a primary sleeve and a secondary sleeve. The adhesive outlet of the storage tube is inserted into a guide post of the secondary sleeve. The guide post is installed at the rivet hole requiring adhesive injection, guiding the adhesive outlet. A knob is used to push the storage tube axially, causing the adhesive outlet to move along the axis of the guide post, thus allowing the adhesive hole to enter the rectangular steel beam. Twisting the knob causes the threaded rod to move axially towards the adhesive outlet, achieving adhesive extrusion. In this invention, multiple adhesive holes are arranged at an angle, allowing the adhesive to be sprayed in an umbrella shape around the rivet holes on the inner wall of the rectangular steel beam during extrusion, achieving directional adhesive application.

[0017] This invention utilizes a graduated dial on the upper surface of the chuck of the knob lever and a pointer on the end of the threaded rod protruding from the glue reservoir. These two elements work together to indicate the angle during the knob's rotation, thereby controlling the extrusion process of the threaded rod. By setting the rotation angle corresponding to the glue dispensing amount on the scale, quantitative control of the glue dispensing amount can be ensured, achieving consistency in the amount of glue extruded each time.

[0018] This invention, through the cooperation of a spring, a glue reservoir tube, and a secondary sleeve, ensures both the elastic downward pressure of the glue reservoir tube during glue dispensing and its elastic return after dispensing. This allows the glue orifice of the dispensing head to protrude from the guide post during dispensing and retract into the guide post when dispensing, with the guide post acting as a seal for the glue orifice. This structure, on the one hand, allows the glue reservoir tube to spring back after dispensing, quickly cutting off the glue; on the other hand, it achieves a seal for the glue orifice, preventing accidental dispensing due to misoperation of the knob.

[0019] The adhesive injection device for rivet holes in modular shelters provided by this invention effectively improves the sealing of adhesive during riveting, ensuring that the adhesive can be applied to the contact surface between the rivet and the inner wall of the rectangular steel beam. Furthermore, the amount of adhesive used is controllable, the application is uniform, and the device is highly operable, effectively guaranteeing the sealing of the rivet holes and improving adhesive application efficiency.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] An embodiment of the adhesive injection device for rivet holes in a modular shelter according to the present invention, such as... Figure 2 , Figure 3 and Figure 4 As shown, the device includes a primary sleeve 1, a secondary sleeve 2, a glue storage tube 3, a spring 4, a knob rod 5, and a threaded rod 6.

[0025] like Figure 9 As shown, the first-stage sleeve 1 is a hollow cylindrical body with open ends. One end of its inner wall is provided with an internal thread 11, which is used for threaded connection with the second-stage sleeve 2.

[0026] like Figure 10 , Figure 11 As shown, the secondary sleeve 2 is a cylindrical stepped structure with one open end and a base plate at the other end. The open end has an external thread 23. The open end of the secondary sleeve 2 is threaded into the internal thread 11 of the primary sleeve 1, forming a threaded connection, thus connecting the inner cavity of the secondary sleeve 2 with the inner cavity of the primary sleeve 1. A hollow guide post 21, penetrating the inner cavity of the secondary sleeve 2, is located at the center of the base plate of the secondary sleeve 2. The guide post 21 is a hollow cylindrical structure and is used to cooperate with the dispensing head 33 of the glue storage tube 3, guiding its axial movement. An axial limiting platform 22 is provided within the inner cavity of the secondary sleeve 2 to prevent the glue storage tube 3 from dislodging from the secondary sleeve 2. Figure 11As shown, in this embodiment, the secondary sleeve 2 is a two-half split structure along its axis. The two halves are completely symmetrical and, after being joined together, form an integral secondary sleeve 2. The two-half split structure facilitates the installation of the glue storage tube 3 and the spring 4.

[0027] like Figure 3 , Figure 12 As shown, the glue storage tube 3 is axially movable within the inner cavities of the primary sleeve 1 and the secondary sleeve 2, and is used for storing glue. The glue storage tube 3 includes a glue storage tube body 31, a retaining ring 32 disposed on the outer diameter wall of the glue storage tube body 31, and a glue outlet 33 coaxially disposed at one end of the glue storage tube body 31. The glue storage tube body 31 is a cylindrical tube, and its inner cavity forms a glue storage chamber for storing glue. The retaining ring 32 is disposed near the glue outlet 33 and located inside the secondary sleeve 2. The retaining ring 32 is used to cooperate with the limiting platform 22 inside the secondary sleeve 2 to form an axial limit to prevent the glue storage tube 3 from falling out. The dispensing head 33 is a cylindrical hollow structure. The inner cavity of the dispensing head 33 is connected to the glue storage chamber of the glue storage tube 31. The end of the dispensing head 33 is closed. Four glue holes 34 are evenly distributed around the circumference of the dispensing head 33. The glue holes 34 are used for dispensing glue. The dispensing head 33 is inserted into the guide post 21. In this embodiment, the glue holes 34 are inclined holes, with their inclination direction facing the glue storage tube 31, facilitating the formation of an umbrella-shaped glue column during extrusion and application to the glue. Figure 1 The adhesive sealing position 10 is shown. When the glue storage tube 3 moves axially, the glue dispensing head 33 moves axially within the guide post 21. When glue needs to be dispensed, the glue storage tube 3 is pushed so that the glue hole 34 of the glue dispensing head 33 protrudes out of the guide post 21. After the glue is dispensed, it is reset by the spring 4.

[0028] In this embodiment, the glue storage tube 3 is made of polytetrafluoroethylene, which has non-stick properties and is convenient for storing and cleaning glue.

[0029] Spring 4 is installed inside the secondary sleeve 2 and fitted onto the outer diameter of the glue storage tube 3. One end of spring 4 contacts the retaining ring 31, and the other end contacts the inner wall of the secondary sleeve 2. It is used for elastic reset after the glue storage tube 3 moves axially and dispenses glue. Figure 3 , Figure 4 As shown, when the glue storage tube 3 is pushed downward so that the glue hole 34 of the glue head 33 is exposed outside the guide post 21, the spring 4 is squeezed. When the downward axial thrust of the glue storage tube 3 is removed, the restoring force of the spring 4 pushes the retaining ring 32 of the glue storage tube 3 upward until the retaining ring 32 moves upward to the limiting platform 22 of the secondary sleeve 2, thus completing the reset of the glue storage tube 3.

[0030] like Figure 3 As shown, the knob rod 5 and the threaded rod 6 form a screw extrusion assembly, which pushes the glue storage tube 3 to move axially toward the guide post 21 and quantitatively extrudes the glue inside the glue storage tube 3.

[0031] like Figure 5 , Figure 6As shown, the knob lever 5 includes a chuck 51 and an operating lever 52. The chuck 51 has a disc structure, and its outer diameter is adapted to the inner diameter of the first-stage sleeve 1, allowing it to be inserted into the first-stage sleeve 1. Two operating levers 52 are provided, symmetrically installed on both sides of the chuck 51 and fixed to it. The operating levers 52 are used for hand-operating the axial movement and rotation of the chuck 51. A threaded hole 53 is provided in the center of the chuck 51 for inserting a threaded rod 6.

[0032] The lower end of the chuck 51 covers the open end of the primary sleeve 1 away from the secondary sleeve 2, and the lower end face of the chuck 51 contacts the end of the glue storage tube 3 away from the glue outlet 33. For example... Figure 3 As shown, when the hand-held operating lever 52 is pressed axially downwards on the chuck 51, the lower end of the chuck 51 will be embedded in the first-stage sleeve 1. At this time, the operating levers 52 on both sides contact the end face of the first-stage sleeve 1 to form an axial limit. If the chuck 51 is rotated at this time, the outer diameter of the lower end of the chuck 51 forms a circumferential limit with the first-stage sleeve 1, so that the chuck 51 rotates in the first-stage sleeve 1.

[0033] like Figure 7 , Figure 8 As shown, the threaded rod 6 includes a screw body 61 and an extrusion disc 62. The screw body 61 is vertically inserted into the threaded hole 53 of the chuck, and the two are threadedly connected. One end of the screw body 61 extends into the glue storage tube 3, and the extrusion disc 62 is provided at this end. The extrusion disc 62 is used for extruding glue. Rotating the knob 5 drives the threaded rod 6 to move axially to extrude glue in a metered manner.

[0034] When the chuck 51 pushes the glue storage tube 3 downward, the glue hole 34 of the glue outlet 33 protrudes from the guide post 21. Then, the chuck 51 is rotated, and the chuck 51 and the threaded rod 6 move relative to each other, causing the threaded rod 6 to move axially toward the glue outlet 33 to squeeze the glue, so that the glue is squeezed out of the glue hole 34. It should be noted that the depth to which the lower end of the chuck 51 is embedded in the first-stage sleeve 1 must ensure the working depth of the glue hole 34 of the glue outlet 33 when it enters the rectangular steel beam to dispense glue.

[0035] like Figure 6 , Figure 7 As shown, in order to achieve quantitative control of the extrusion amount, the present invention provides a scale 54 on the upper end face of the chuck 51, i.e., the end face facing away from the first-stage sleeve 1. The scale 54 is arranged around the threaded hole 53, and the graduation value of the scale 54 is preferably 10°. A pointer 63 is provided at the end of the screw body 61 away from the extrusion plate 62. The pointer 63 cooperates with the scale 54 to indicate the current position and turning angle of the knob 5, thereby realizing quantitative extrusion.

[0036] When using, first assemble the glue dispensing device. During assembly, first install the glue storage tube 3 into the first-stage sleeve 1, then install the spring 4 on the glue storage tube 3, then connect the two halves of the second-stage sleeve 2 so that the spring 4 is located inside the second-stage sleeve 2, and the retaining ring 32 of the glue storage tube 3 is locked inside the limiting platform 22. Then, thread the second-stage sleeve 2 and the first-stage sleeve 1 together and fix them. Then, thread the threaded rod 6 through the knob rod 5, then extend one end of the extrusion plate 62 of the threaded rod 6 into the glue storage tube 3, and make the retaining plate 51 of the knob rod 5 contact the top of the glue storage tube 3 (i.e., the end away from the glue dispensing head 33) to complete the assembly.

[0037] like Figure 13 and Figure 14 As shown, when using the glue injection device of the present invention to inject glue into the rivet holes of the square compartment, first insert the guide post 21 vertically into the rivet hole, then press down the knob rod 5, the chuck 51 squeezes the glue storage tube 3 downward, at this time the spring 4 will be squeezed by the retaining ring 32, the knob rod 5 is pressed down until the operating rod 52 contacts the first-stage sleeve 1, the glue outlet head 33 at the lower end of the glue storage tube 3 moves down to the glue outlet working position, that is, the glue hole 34 of the glue outlet head 33 protrudes from the guide post 21 and enters the inner cavity of the rectangular steel beam 8 of the large plate. At this time, rotate the knob rod 5 to make the threaded rod 6 move down to squeeze out the glue. Since the four glue holes 34 are inclined upward, when the threaded rod 6 moves down to squeeze out the glue, the squeezed glue 101 forms an umbrella-shaped spray of glue column, such as Figure 14 As shown in the enlarged view, the adhesive is precisely and evenly applied to the adhesive sealing position 10, i.e., the inner wall of the rectangular steel beam 8 around the rivet hole. During adhesive dispensing, the amount of adhesive dispensed is determined by the pointer 63 and the dial 54. The knob 5 remains pressed down during rotation. After dispensing is complete, the knob 5 is stopped, and under the restoring force of the spring 4, the adhesive reservoir 3 moves upward to its original position, and the dispensing head 33 retracts into the guide post 21, cutting off the adhesive column and sealing the adhesive hole 34. The adhesive dispensing device is then removed, and the next rivet hole is dispensed. Once the rivet hole dispensing is complete, the riveting operation can begin.

[0038] 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.
