Description
Technical Field
[0001] This utility model belongs to the field of metal plug installation tools, specifically relating to a handheld metal plug removal and pasting tool. Background Technology
[0002] The sealing performance of the vehicle body is closely related to its corrosion resistance, vibration damping, and noise reduction, and is one of the important evaluation indicators of overall vehicle quality. It also directly affects the user's driving and riding experience. Therefore, during the vehicle body production process, various large-sized process holes, fluid outlets, structural holes, etc., on the vehicle body need to be sealed with metal plugs.
[0003] Currently, most commonly used metal plugs are composed of a 0.6mm thick galvanized steel or aluminum sheet coated with a 1.2mm thick butyl rubber layer. They are typically cut into a circle and glued onto a backing paper. Traditionally, when using metal plugs to seal holes, the metal plug needs to be manually peeled off the backing paper and then glued on. However, during this process, fingers can easily touch the butyl rubber surface, contaminating the adhesive surface with grease, sweat, dust, etc. Once the adhesive surface is contaminated, the adhesion of the metal plug decreases, leading to problems such as loose adhesion and lifting edges, ultimately affecting the vehicle's sealing performance.
[0004] To address this issue, on-site workers began developing various auxiliary tools to prevent their fingers from directly contacting the adhesive surface of the metal caps. However, existing tools still have certain drawbacks. For example, a common tool with a magnet at the end of a long rod often requires overcoming the magnet's attraction to the metal cap to separate the tool from it. This process not only requires considerable effort but can also negatively impact the adhesive strength. Additionally, some tools utilize suction cups for installing metal caps. However, these tools use ordinary flared suction cups that rely on squeezing to adhere to the cap. Like the aforementioned tools, separating the suction cup from the cap also requires considerable effort and can affect the adhesive strength. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing metal cap installation auxiliary tools, which require considerable effort to use and easily affect the bonding strength when separating from the metal cap. A new handheld metal cap removal and bonding tool is proposed and designed to overcome these problems, ensuring the bonding quality of the metal cap while avoiding accidental contact with the butyl rubber surface.
[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a handheld metal cap removal and pasting tool, comprising a fixed sleeve, which is a cylindrical structure with one end open and the other end sealed. A return spring and a slider are slidably installed sequentially from the inside to the outside of the cavity of the fixed sleeve. An abutment portion is provided on the slider near the return spring, abutting with the return spring. A control trigger is provided in the middle of the slider, extending out of the fixed sleeve. A connecting portion is provided on the slider away from the return spring, and the connecting portion has a threaded hole. A screw is threaded into the threaded hole, and one end of the screw extends out of the threaded hole and is fixedly connected to a suction cup. The end of the suction cup away from the screw is located outside the fixed sleeve. The side of the suction cup near the screw is a non-working surface, abutting with the open end of the fixed sleeve. The side of the suction cup away from the screw is a working surface. When the return spring is in a relaxed state, the working surface is flat; when the return spring is in a compressed state, the working surface is concave. At this time, when using this utility model to remove and attach the metal plug, first hold the tool and align it with the corresponding metal plug, ensuring the working surface of the tool's suction cup is tightly against the metal plug. Then pull the control trigger, causing the slider and the suction cup connected to the slider to slide inward within the fixed sleeve. At this time, the return spring is further compressed, and the end of the suction cup away from the screw deforms under the action of the open port of the fixed sleeve, forming a cavity between the working surface of the suction cup and the metal plug. Moreover, because the suction cup was previously... The metal cap fits tightly against the suction cup, preventing air from entering the cavity and creating negative pressure that adheres the metal cap to the suction cup. Next, by holding the trigger still, the metal cap can be peeled off the backing paper, moved to the desired location on the vehicle body, and then attached to the hole. Finally, releasing the trigger causes the slider and the suction cup connected to it to move forward towards the fixed sleeve under the action of the return spring. Simultaneously, the suction cup returns to its original shape, the negative pressure cavity is eliminated, and the metal cap detaches from the suction cup. Therefore, when using this invention to peel off and stick the metal cap, the direction of the suction cup's force on the metal cap is always the same as the direction of the metal cap's movement. This ensures that this invention not only avoids accidental contact with the butyl rubber surface and contamination of the butyl rubber surface, but also allows for a secondary pressing of the metal cap during the separation of the suction cup and the metal cap, thus ensuring the bonding quality of the metal cap. In particular, compared with existing metal cap installation tools, this invention not only avoids pulling the metal cap in the opposite direction, but also uses the reaction force of the return spring to apply a certain pressing force to the metal cap, thereby strengthening the bonding strength of the metal cap.
[0007] Furthermore, the end face of the opening of the fixed sleeve is a concave arc-shaped surface to accommodate the deformation of the suction cup when it is pulled.
[0008] Furthermore, a thickened portion is provided on the outer wall of the open end of the fixed sleeve, and the contact area between the fixed sleeve and the suction cup is increased through this thickened portion.
[0009] Furthermore, the wall of the fixed sleeve has a first slot and a second slot, which are arranged opposite to each other; the surface of the slider has an operating channel, the two ends of which are aligned with the first slot and the second slot, respectively; the control trigger has an elongated section, the width of which is less than the opening length of the first slot, the width of which is less than the opening length of the second slot, the width of which is less than the opening length of the operating channel, the thickness of which is less than the opening width of the first slot, the width of which is less than the opening width of the second slot, and the width of which is less than the opening width of the operating channel; one end of the elongated section is hinged to the first slot by a trigger fastener, and the other end of the elongated section passes through the first slot, the operating channel, and the second slot in sequence, extends out of the fixed sleeve, and is provided with a control ring; the side wall of the elongated section abuts against the side of the operating channel away from the suction cup. At this time, by fastening the control ring, the elongated section of the control trigger can be rotated within the operating channel, and the abutment between the elongated section and the operating channel causes the slider to slide inward within the fixed sleeve, thereby compressing the return spring.
[0010] Furthermore, the length of the opening at the end of the operating channel facing the first slot is greater than the length of the opening at the end of the operating channel facing the second slot, and this is intended to ensure that the control trigger can control the sliding within the slider.
[0011] Furthermore, a weight-reducing hole is provided in the middle of the slider. At this time, most of the material in the middle of the slider is removed, and only the material at the top and bottom is retained for connection, thereby reducing the weight of the slider and the entire tool, so as to reduce the fatigue of the operator.
[0012] Furthermore, the weight reduction hole is located in the middle of the operating channel and runs through the entire operating channel. This achieves both the purpose of weight reduction and facilitates the machining of the entire slider.
[0013] Furthermore, the inner cavity of the fixed sleeve is cylindrical, the slider is cylindrical, the outer diameter of the return spring is the same as the diameter of the slider, and the diameter of the return spring is smaller than the inner diameter of the fixed sleeve, so as to ensure that the slider can slide inside the fixed sleeve and the return spring can undergo elastic deformation inside the fixed sleeve.
[0014] Furthermore, a handle is installed on the outer wall of the fixed sleeve, which facilitates the operator in holding the tool for operation.
[0015] Furthermore, the end of the grip is provided with a mounting groove, and the groove wall is provided with fixing holes; a mounting plate is fixedly mounted on the outer wall of the fixing sleeve, and the mounting plate is inserted into the mounting groove; the surface of the mounting plate has through mounting holes, and the mounting plate is connected to the grip through grip fasteners that pass through the mounting holes and fixing holes, and the grip fasteners can be either pins or screws. Moreover, when the grip fastener is a screw, fixing holes can be provided on both sides of the mounting groove, and the fixing hole on one side of the mounting groove can be set as a threaded hole. In this case, the screw will be threaded into the corresponding threaded hole after passing through the mounting hole, thereby realizing the detachable connection between the mounting plate and the grip.
[0016] As can be seen from the above technical solutions, this utility model has the following advantages: When using this utility model to peel off and stick the metal cap, this utility model can not only avoid the problem of accidentally touching the butyl rubber surface and contaminating the butyl rubber surface, but also press the metal cap a second time during the process of separating the suction cup and the metal cap, thereby ensuring the bonding quality of the metal cap.

Detailed Implementation
[0020] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0021] like Figures 1 to 5 As shown, this utility model provides a handheld metal cap removal and pasting tool, which includes a fixing sleeve 2, a slider 24, a return spring 16, a suction cup 1, a control trigger 7, and a handle 5. The fixing sleeve 2 is a cylindrical structure with one open end and one sealed end. The outer wall of the open end of the fixing sleeve 2 is provided with a thickened portion 8 to increase the contact area between the fixing sleeve 2 and the suction cup 1. The end face of the open end of the fixing sleeve 2 is a concave arc-shaped surface 22 to accommodate the deformation of the suction cup 1 when pulled. A first slot 14 penetrates the upper part of the cylindrical wall of the fixing sleeve 2, and a second slot 19 penetrates the lower part of the cylindrical wall of the fixing sleeve 2. The first slot 14 and the second slot 19 are arranged opposite each other for mounting the control trigger 7. An mounting plate 25 is fixedly installed on the outer wall of the fixed sleeve 2. The surface of the mounting plate 25 has through holes. The handle is installed by the cooperation of the mounting plate 25, the mounting holes and the handle fastener 6, so that the operator can hold the tool to work.
[0022] Specifically, such as Figure 2 , Figure 3 , Figure 5 As shown, the present invention provides a mounting groove 26 at the end of the grip 5, and a fixing hole 27 is provided in the groove wall of the mounting groove 26; the mounting groove 26 of the grip 5 is inserted into the mounting plate 25, and the fixing hole 27 of the grip 5 is aligned with the mounting hole of the mounting plate 25. At this time, the mounting plate 25 can be connected to the grip 5 by a grip fastener 6 that passes through the mounting hole and the fixing hole 27. Moreover, the grip fastener 6 can be either a pin or a screw. For example, when the grip fastener 6 is a screw, fixing holes 27 can be provided on both sides of the mounting groove 26, and the fixing hole 27 on one side of the mounting groove 26 can be set as a threaded hole. In this case, the screw will be threaded into the corresponding threaded hole after passing through the mounting hole, thereby realizing the detachable connection between the mounting plate 25 and the grip 5. When the grip fastener 6 is a pin, fixing holes 27 can be provided on one or both sides of the mounting groove 26, and the pin directly passes through the fixing hole 27 and the mounting hole, thereby realizing the detachable connection between the mounting plate 25 and the grip 5.
[0023] The return spring 16 and the slider 24 are installed sequentially from the inside to the outside in the cavity of the fixed sleeve 2. The slider 24 is cylindrical in shape. The outer diameter of the return spring 16 is the same as the diameter of the slider 24. The diameters of the return spring 16 and the slider 24 are both slightly smaller than the inner diameter of the fixed sleeve 2 to ensure that the slider 24 can slide inside the fixed sleeve 2 and that the return spring 16 can undergo elastic deformation inside the fixed sleeve 2.
[0024] Meanwhile, the slider 24 in this utility model is further divided into an abutment portion 15, a mating portion 23, and a connecting portion 18 along the direction away from the return spring 16. Specifically, as shown... Figure 2 , Figure 3 , Figure 4 As shown, the end of the slider 24 near the return spring 16 is an abutment portion 15, which abuts against the return spring 16 to ensure that the slider 24 can compress the return spring 16 and that the return spring 16 can drive the slider 24 to slide. The middle part of the slider 24 is a mating portion 23, and an operating channel 13 penetrates the surface of the mating portion 23. The upper and lower ends of the operating channel 13 are aligned with the first slot 14 and the second slot 19, respectively. The opening length of the end of the operating channel 13 facing the first slot 14 is greater than the opening length of the end of the operating channel 13 facing the second slot 19, to ensure that the control trigger 7 can control the slider 24 to slide. Furthermore, preferably, a weight-reducing hole 17 can be horizontally penetrated through the middle of the mating portion 23, that is, a weight-reducing hole 17 is horizontally penetrated at the middle position of the operating channel 13. At this point, since most of the material in the middle of the slider 24 has been removed, leaving only the upper and lower materials for connection, the weight of the slider 24 and the entire tool can be reduced, thereby reducing the fatigue of the operator.
[0025] The end of the slider 24 away from the return spring 16 is a connecting part 18, and the end face of the connecting part 18 is provided with a threaded hole 12. A screw 11 is internally threaded into the threaded hole 12. One end of the screw 11 extends out of the threaded hole 12 and is fixedly connected to a suction cup 1. The end of the suction cup 1 away from the screw 11 is located outside the fixed sleeve 2. At the same time, the side of the suction cup 1 near the screw 11 is a non-working surface 9, which abuts against the open end of the fixed sleeve 2. The side of the suction cup 1 away from the screw 11 is a working surface 10. When the slider 24 does not compress the return spring 16, that is, when the return spring 16 is in a relaxed state, the working surface 10 is a plane. When the slider 24 compresses the return spring 16 inward, that is, when the return spring 16 is in a relatively compressed state, the working surface 10 is a concave surface.
[0026] The control trigger 7 is provided with an elongated section 21. The width of the elongated section 21 is less than the opening length of the first slot 14, the width of the elongated section 21 is less than the opening length of the second slot 19, the width of the elongated section 21 is less than the opening length of the operating channel 13, the thickness of the elongated section 21 is less than the opening width of the first slot 14, the width of the elongated section 21 is less than the opening width of the second slot 19, and the width of the elongated section 21 is less than the opening width of the operating channel 13. Furthermore, one end of the elongated section 21 is hinged to the trigger connecting supports 3 provided on both sides of the first slot 14 via the trigger fastener 4. When the trigger fastener 4 adopts a bolt structure, the stud of the trigger fastener 4 can pass through the first trigger connecting support 3, the elongated section 21, and the second trigger connecting support 3 in sequence, and then be threadedly connected to a nut of the corresponding size. This ensures that there is a gap between the stud of the trigger fastener 4 and the wall of the through hole provided on the elongated section 21, and there are gaps between the two sides of the elongated section 21 and the two trigger connecting supports 3, thus ensuring that the elongated section 21 can rotate around the trigger fastener 4. The other end of the elongated section 21 passes through the first slot 14, the operating channel 13, and the second slot 19 in sequence, extends out of the fixing sleeve 2, and is provided with a control ring 20. Moreover, the side wall of the elongated section 21 abuts against the side of the operating channel 13 away from the suction cup 1. At this time, the present invention can operate the long strip 21 of the control trigger 7 to rotate in the operation channel 13 by fastening the control ring 20. The contact between the long strip 21 and the operation channel 13 drives the slider 24 to slide inward in the fixed sleeve 2 to compress the return spring 16.
[0027] Based on this, when assembling this utility model, the return spring 16 and the slider 24 can be placed into the fixed sleeve 2 in sequence, and the head end of the slider 24 (the end with the threaded hole 12) can be aligned with the opening end of the fixed sleeve 2; then the position and angle of the slider 24 can be adjusted so that the openings on both sides of the slider 24 are aligned with the first slot 14 and the second slot 19 on both sides of the fixed sleeve 2 respectively; next, the control trigger 7 can be inserted into the second slot 19 at the lower end of the fixed sleeve 2, and it can be inserted into the operating channel 1 through the slider 24. 3. Then, the control trigger 7 is inserted through the first slot 14 at the upper end of the fixed sleeve 2. Then, the trigger fastener 4 is used to install the control trigger 7 on the trigger connecting support 3 on the outer wall of the fixed sleeve 2. At the same time, the grip 5 is installed on the mounting plate 25 at the lower end of the fixed sleeve 2 using the two grip fasteners 6. Finally, the suction cup 1 is installed on the slider 24 inside the fixed sleeve 2 through the pre-embedded screw 11 at its tail, and the suction cup 1 is screwed until the back of the suction cup 1 (i.e., the non-working surface 9) contacts the end face of the fixed sleeve 2.
[0028] When using this utility model to remove and attach metal plugs, first hold the tool and align it with the corresponding metal plug, ensuring the working surface 10 of the suction cup 1 is tightly against the metal plug. Then, pull the control trigger 7, causing the slider 24 and the suction cup 1 connected to the slider 24 to slide inward within the fixed sleeve 2. At this time, the return spring 16 is further compressed, and the end of the suction cup 1 away from the screw 11 deforms under the action of the open port of the fixed sleeve 2, forming a cavity between the working surface 10 of the suction cup 1 and the metal plug. Moreover, because the suction cup 1 Previously, the metal plug was tightly fitted, and no air entered the cavity, creating a negative pressure that attracted the metal plug onto the suction cup 1. Next, by holding the control trigger 7 still, the metal plug can be peeled off the backing paper, moved to the location on the vehicle body where the hole needs to be sealed, and then pasted onto the hole. Finally, the control trigger 7 is released, and the slider 24 and the suction cup 1 connected to the slider 24 move forward towards the fixed sleeve 2 under the action of the return spring 16. At the same time, the suction cup 1 returns to its original shape, the negative pressure cavity is eliminated, and the metal plug detaches from the suction cup 1.
[0029] Therefore, when using this invention to remove and attach the metal cap, since the direction of the force exerted by the suction cup 1 on the metal cap is always the same as the direction of movement of the metal cap, this invention can not only avoid the problem of accidentally touching the butyl rubber surface and contaminating the butyl rubber surface, but also apply a certain pressing force to the metal cap by using the reaction force of the return spring 16 during the process of separating the suction cup 1 from the metal cap, thereby strengthening the bonding strength of the metal cap.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
