Description

Technical Field

[0001] This utility model relates to the technical field of glue extrusion tools, and in particular to a glue gun. Background Technology

[0002] A caulking gun is a tool for applying silicone sealant to seal gaps and is widely used in industries such as construction, decoration, electronics, automobiles and auto parts, shipbuilding and containers.

[0003] In related technologies, a glue extrusion gun includes a barrel and a handle. The barrel is used to hold a glass glue tube, and the handle is connected to one end of the barrel. The handle is equipped with a glue extrusion mechanism, which is used to squeeze the glass glue tube inside the barrel to expel glue.

[0004] In caulking operations, when passing through corners, it is necessary to adjust the angle of the grip on the gun handle for ease of operation. To prevent the gun barrel from rotating with the handle after adjusting the grip angle, which would result in the silicone sealant extruded from the gun not filling the gaps at the corners smoothly, Chinese utility model patent with announcement number CN218309037U discloses a glue extrusion gun that rotates the handle and the gun barrel so that the gun barrel can maintain its original angle when the grip angle is adjusted.

[0005] However, when the gun handle rotates relative to the gun barrel, the extrusion mechanism twists the silicone tube inside the gun barrel into a contorted shape, which can easily cause the silicone tube packaging bag inside the gun barrel to break and increase the difficulty of extruding silicone from the silicone tube inside the gun barrel. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a glue gun that can prevent the extrusion mechanism from twisting the glass glue tube inside the gun barrel into a contorted shape when the gun handle rotates relative to the gun barrel, thereby avoiding the rupture of the glass tube packaging bag inside the gun barrel and increasing the difficulty of extruding the glass glue from the glass glue tube inside the gun barrel.

[0007] A glue gun according to an embodiment of the present utility model includes:

[0008] The barrel is used to hold the glass glue tube, and one end has a glue nozzle.

[0009] The gun handle is rotatably connected to the other end of the gun barrel;

[0010] An extrusion mechanism is connected to the gun handle, which drives the extrusion mechanism to squeeze the glass glue tube inside the gun barrel so that the glass glue in the glass glue tube is squeezed out from the dispensing nozzle.

[0011] The extrusion mechanism includes a push rod, a pressing module, and a connecting assembly. The push rod is connected to the gun handle. The pressing module is rotatably disposed at one end of the push rod located inside the gun barrel. The connecting assembly is used to connect the push rod and the pressing module. The pressing module is used to abut against the glass tube inside the gun barrel.

[0012] A glue gun according to an embodiment of the present utility model has at least the following beneficial effects:

[0013] 1. This utility model connects the gun handle and the gun barrel by rotation, so that the angle of the gun barrel is fixed while the gun handle can rotate freely. The user can adjust the grip posture at will, while ensuring the stability of the glue dispensing path and improving the smoothness of the caulking.

[0014] 2. This utility model connects the push rod and the gun handle via a transmission mechanism. The pressure module is rotatably mounted at one end of the push rod located inside the gun barrel. A connecting component is used to connect the push rod and the pressure module. The pressure module is used to abut against the glass glue tube inside the gun barrel. It can be understood that when the gun handle is rotated to adjust the angle, the pressure module can rotate independently to prevent the torque of the push rod from being transmitted to the glass glue tube, preventing the glue tube from being twisted and reducing the risk of packaging bag breakage. At the same time, it avoids increasing the difficulty of extruding the glass glue from the glass glue tube inside the gun barrel. In addition, the pressure module and the glass glue tube remain relatively stationary, reducing frictional resistance and ensuring smooth extrusion of the glass glue, which is especially suitable for corner operations.

[0015] According to some embodiments of the present invention, the connecting component is fixedly installed at one end of the push rod, the connecting component is provided with a first annular groove, the pressing module is rotatably disposed on the first annular groove, and the first annular groove limits the pressing module to prevent it from detaching.

[0016] The advantages of this invention are: by fixing the connecting component to one end of the push rod, the connecting component is provided with a first annular groove, and the pressing module is rotatably mounted on the first annular groove. The first annular groove limits and prevents the pressing module from detaching. It can be understood that the connecting component realizes the rotational installation and anti-detachment of the pressing module through the first annular groove. On the one hand, the design of the first annular groove realizes the integration of rotation and limiting in a limited space, reducing the assembly complexity. On the other hand, the physical constraint of the first annular groove on the pressing module prevents it from detaching from the push rod, ensuring long-term stability.

[0017] According to some embodiments of the present invention, the connecting assembly includes a limiting sleeve and a first nut. The limiting sleeve is disposed at one end of the push rod and abuts against the end of the push rod for limiting. The end of the push rod is provided with a screw portion, which passes through the limiting sleeve. The first nut is threadedly connected to the screw portion and abuts against the end of the limiting sleeve away from the push rod to fix the limiting sleeve. The end of the limiting sleeve away from the push rod is provided with a first recess, and a first annular groove is formed between the first recess and the first nut.

[0018] The advantages of this invention are as follows: The connecting assembly includes a limiting sleeve and a first nut. The limiting sleeve is located at one end of the push rod, abutting against the end of the push rod for limitation. The end of the push rod has a threaded portion that passes through the limiting sleeve. The first nut is threadedly connected to the threaded portion, and abuts against the end of the limiting sleeve away from the push rod to fix the limiting sleeve. The end of the limiting sleeve away from the push rod has a first recess, forming a first annular groove between the first recess and the first nut. It can be understood that the connecting assembly consists of a limiting sleeve and a first nut, and the first annular groove is formed by the recess of the limiting sleeve and the first nut. Therefore, the separate design of the limiting sleeve and the first nut facilitates the disassembly and installation of the pressure module from the first annular groove, reducing the installation difficulty of the pressure module. Furthermore, the threaded locking of the first nut provides a stable preload, preventing axial movement of the limiting sleeve and ensuring the durability of the first annular groove structure.

[0019] According to some embodiments of the present invention, the limiting sleeve is fitted onto the end of the push rod, and the inner wall of the limiting sleeve is provided with an inner convex ring, which abuts against and limits the end of the push rod.

[0020] The advantages of this invention are: by fitting a limiting sleeve onto the end of the push rod, and the inner wall of the limiting sleeve being provided with an inner convex ring, the inner convex ring abutting and limiting the end of the push rod, it can be understood that fitting the limiting sleeve onto the end of the push rod makes the positioning of the limiting sleeve and the push rod more accurate, avoids the installation offset of the limiting sleeve, and ensures the coaxiality of the pressing module and the push rod. In addition, the abutting and limiting of the inner convex ring with the end of the push rod allows the end of the push rod to support the limiting sleeve, preventing the limiting sleeve from moving axially.

[0021] According to some embodiments of the present invention, the pressing module is provided with a first mounting through hole, which is sleeved on the first annular groove, and the width of the first annular groove is greater than the depth of the first mounting through hole.

[0022] The advantage of this invention is that by providing a first mounting through hole in the pressing module, and the first mounting through hole being fitted onto the first annular groove, the width of the first annular groove being greater than the depth of the first mounting through hole, it can be understood that the dimensional difference between the first annular groove and the first mounting hole provides axial floating space for the pressing module, preventing the sidewall of the first annular groove from rubbing against the first mounting through hole and ensuring smooth rotation.

[0023] According to some embodiments of the present invention, the connecting component is configured as a rotary bearing, the inner ring of the rotary bearing is connected to the push rod, and the outer ring of the rotary bearing is connected to the pressing module.

[0024] The advantage is that by setting the connecting component as a rotating bearing, with the inner ring of the rotating bearing connected to the push rod and the outer ring of the rotating bearing connected to the pressing module, it can be understood that using a rotating bearing as the transmission component between the push rod and the pressing module can reduce the rotational frictional resistance of the pressing module, making the rotation of the pressing module smoother.

[0025] According to some embodiments of the present invention, the pressing module includes a first pressing member and a second pressing member. The first pressing member is connected to the connecting assembly, and the second pressing member is detachably connected to the first pressing member. The first pressing member is made of metal and is used to press against a hard-shell packaged glass tube. The second pressing member is made of plastic and is used to press against a soft-shell packaged glass tube.

[0026] The advantages of this invention are: by including a first pressing component and a second pressing component in the pressing module, the first pressing component is connected to the connecting assembly, and the second pressing component is detachably connected to the first pressing component. The first pressing component is made of metal and is used to press against hard-shell packaged glass glue tubes. The second pressing component is made of plastic and is used to press against soft-shell packaged glass glue tubes. It is understood that glass glue is packaged in hard-shell and soft-bag packaging. For different glass glue packaging, the glue gun needs to change different pressing components to push the glue. By setting a detachably connected first pressing component and second pressing component, it is convenient to switch between the first pressing component and the second pressing component according to different packaging of glass glue tubes, thereby improving the adaptability of the glue gun to different types of packaging of glass glue tubes.

[0027] According to some embodiments of the present invention, the second pressing member is provided with a slot, the slot being used to engage the edge of the first pressing member, the slot being abutting and limiting the first pressing member on both sides along the length direction of the push rod, the slot opening being located on one side of the second pressing member along the radial direction of the push rod, and the slot opening accommodating the first pressing member entering the slot.

[0028] The advantages of this invention are: A groove is provided in the second pressing member to engage with the edge of the first pressing member. The groove abuts against and limits the first pressing member on both sides along the length of the push rod. The opening of the groove is located on one side of the second pressing member along the radial direction of the push rod. The opening of the groove accommodates the first pressing member entering the groove. It can be understood that the groove abuts against both sides of the first pressing member to prevent axial loosening of the second pressing member. Furthermore, the groove on the radial side of the second pressing member allows the first pressing member to be pushed laterally into the groove of the second pressing member for engagement, eliminating the need for thread alignment or precise positioning and simplifying the assembly process.

[0029] According to some embodiments of the present invention, the slot has an opening on the side near the push rod, the opening extending radially along the push rod to the slot opening of the slot, and the opening is used to avoid the push rod.

[0030] The advantage of this invention is that by providing an opening on the side of the slot near the push rod, the opening extends radially along the push rod to the opening of the slot. The opening is used to avoid the push rod. It can be understood that the opening provides space for the push rod to avoid interference, ensuring that the slot fits into the first pressing member so that the second pressing member can avoid the push rod and avoid interference between the second pressing member and the push rod.

[0031] According to some embodiments of the present invention, a retaining strip is provided on the side of the second pressing member near the groove opening of the card slot. One end of the retaining strip is connected to the second pressing member, and a protrusion is provided on one side of the retaining strip. The protrusion abuts and limits the first pressing member near the groove opening of the card slot.

[0032] The advantages of this invention are: a retaining strip is provided on the side of the second pressing member near the slot opening, one end of the retaining strip is connected to the second pressing member, and a protrusion is provided on one side of the retaining strip. The protrusion abuts against and limits the first pressing member near the slot opening. It can be understood that the protrusion on the retaining strip forms a mechanical stop on the edge of the first pressing member, which can resist the accidental disengagement of the second pressing member caused by vibration. In addition, after the retaining strip is elastically deformed by external force, it can drive the protrusion to contact and limit the first pressing member, making it convenient to insert the first pressing member into the slot or remove the first pressing member from the slot.

[0033] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0047] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This invention describes a glue gun according to an embodiment of the present invention.

[0048] The present invention aims to provide an embodiment of a glue gun.

[0049] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, a glue gun mainly includes a barrel 100, a handle 120, and a glue extrusion mechanism 130.

[0050] The barrel 100 is used to hold the glass glue tube, and one end of the barrel 100 has a glue outlet 110.

[0051] The gun handle 120 is rotatably connected to the other end of the gun barrel 100, so that the angle of the gun barrel 100 is fixed while the gun handle 120 can rotate freely. The user can adjust the grip posture at will, while ensuring the stability of the glue dispensing path and improving the smoothness of the caulking.

[0052] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7For the extrusion mechanism 130, the extrusion mechanism 130 is connected to the gun handle 120. The gun handle 120 is used to drive the extrusion mechanism 130 to squeeze the glass glue tube in the gun barrel 100 so that the glass glue in the glass glue tube is squeezed out from the dispensing nozzle 110.

[0053] The extrusion mechanism 130 includes a push rod 140, a pressing module 150, and a connecting assembly 160. The push rod 140 is connected to the gun handle 120. The pressing module 150 is rotatably disposed at one end of the push rod 140 located inside the gun barrel 100. The connecting assembly 160 is used to connect the push rod 140 and the pressing module 150. The pressing module 150 is used to abut against the glass tube inside the gun barrel 100.

[0054] It should be explained that the push rod 140 is connected to the gun handle 120 in a transmission manner, which means that the gun handle 120 can drive the push rod 140 to move axially, so that the push rod 140 can drive the pressure module 150 to squeeze the glass tube inside the gun barrel 100.

[0055] Understandably, when the gun handle 120 is rotated to adjust the angle, the pressure module 150 can rotate independently to prevent the torque of the push rod 140 from being transmitted to the glass glue tube, thus preventing the glue tube from being twisted and reducing the risk of packaging bag breakage. At the same time, it avoids increasing the difficulty of extruding the glass glue from the glass glue tube inside the gun barrel 100. In addition, the pressure module 150 and the glass glue tube remain relatively stationary, reducing frictional resistance and ensuring smooth extrusion of the glass glue, which is especially suitable for corner operations.

[0056] In some specific embodiments, the connecting component 160 is fixedly installed at one end of the push rod 140, the connecting component 160 is provided with a first annular groove 170, the pressing module 150 is rotatably mounted on the first annular groove 170, and the first annular groove 170 limits the pressing module 150 to prevent it from falling off.

[0057] It is understandable that the connecting component 160 achieves the rotational installation and anti-detachment of the pressing module 150 through the first annular groove 170. On the one hand, the design of the first annular groove 170 realizes the integration of rotation and positioning in a limited space, reducing the assembly complexity. On the other hand, the physical constraint of the first annular groove 170 on the pressing module 150 prevents it from detaching from the push rod 140, ensuring long-term stability.

[0058] Specifically, the connecting assembly 160 includes a limiting sleeve 180 and a first nut 190. The limiting sleeve 180 is disposed at one end of the push rod 140 and abuts against the end of the push rod 140 for limiting. The end of the push rod 140 is provided with a screw portion 200, which passes through the limiting sleeve 180. The first nut 190 is threadedly connected to the screw portion 200. The first nut 190 abuts against the end of the limiting sleeve 180 away from the push rod 140 to fix the limiting sleeve 180. The end of the limiting sleeve 180 away from the push rod 140 is provided with a first recess, and a first annular groove 170 is formed between the first recess and the first nut 190.

[0059] Understandably, the connecting component 160 consists of a limiting sleeve 180 and a first nut 190. The first annular groove 170 is formed by the recess of the limiting sleeve 180 and the first nut 190 engaging. Thus, the separate design of the limiting sleeve 180 and the first nut 190 facilitates the disassembly and installation of the pressing module 150 from the first annular groove 170, reducing the installation difficulty of the pressing module 150. In addition, the threaded locking of the first nut 190 provides a stable preload, preventing the limiting sleeve 180 from axially moving and ensuring the structural durability of the first annular groove 170.

[0060] Furthermore, the limiting sleeve 180 is fitted onto the end of the push rod 140, and the inner wall of the limiting sleeve 180 is provided with an inner convex ring 210, which abuts against and limits the end of the push rod 140.

[0061] Understandably, the limiting sleeve 180 is fitted onto the end of the push rod 140, making the positioning of the limiting sleeve 180 and the push rod 140 more accurate, avoiding installation misalignment of the limiting sleeve 180, and ensuring the coaxiality of the pressing module 150 and the push rod 140. In addition, the inner convex ring 210 abuts against the end of the push rod 140 to limit its movement, so that the end of the push rod 140 can support the limiting sleeve 180 and prevent the limiting sleeve 180 from moving axially.

[0062] In some specific embodiments, the pressing module 150 is provided with a first mounting through hole 220, which is sleeved on the first annular groove 170. The width of the first annular groove 170 is greater than the depth of the first mounting through hole 220.

[0063] It is understandable that the dimensional difference between the first annular groove 170 and the first mounting hole is used to provide axial floating space for the pressure module 150, preventing the sidewall of the first annular groove 170 from rubbing against the first mounting through hole 220 and ensuring smooth rotation.

[0064] In some specific embodiments, the diameter of the first mounting hole can be slightly larger than the diameter of the first annular groove 170, thereby creating a gap between the first mounting hole and the first annular groove 170 to prevent the first mounting hole from getting stuck in the first annular groove 170.

[0065] In other embodiments, the connecting component 160 may be configured as a rotary bearing, with the inner ring of the rotary bearing connected to the push rod 140 and the outer ring of the rotary bearing connected to the pressing module 150.

[0066] It is understandable that using a rotating bearing as the transmission component between the push rod 140 and the pressing module 150 can reduce the rotational frictional resistance of the pressing module 150, making the rotation of the pressing module 150 smoother.

[0067] In some specific embodiments, the pressing module 150 includes a first pressing member 230 and a second pressing member 240. The first pressing member 230 is connected to the connecting assembly 160, and the second pressing member 240 is detachably connected to the first pressing member 230. The first pressing member 230 is made of metal and is used to press against the glass tube in a hard-shell package. The second pressing member 240 is made of plastic and is used to press against the glass tube in a soft-shell package.

[0068] It is understandable that glass glue is packaged in both hard-shell and soft-bag packaging. For different glass glue packaging, the glue gun needs to change different pressure parts to apply the glue. By setting up a detachable first pressure part 230 and a second pressure part 240, it is convenient to switch between the first pressure part 230 and the second pressure part 240 according to different packaging of glass glue tubes, thereby improving the adaptability of the glue gun to different types of packaging of glass glue tubes.

[0069] Specifically, the second pressing member 240 is provided with a slot 250, which is used to engage the edge of the first pressing member 230. The slot 250 and the first pressing member 230 abut against and limit each other on both sides along the length direction of the push rod 140. The opening of the slot 250 is located on one side of the second pressing member 240 along the radial direction of the push rod 140. The opening of the slot 250 accommodates the first pressing member 230 to enter the slot 250.

[0070] Understandably, the slot 250 abuts against both sides of the first pressing member 230 to prevent the second pressing member from axially loosening. In addition, the slot on the radial side of the second pressing member 240 along the push rod 140 allows the first pressing member 230 to be pushed laterally into the slot 250 of the second pressing member 240 for engagement, without the need for thread alignment or precise positioning, thus simplifying the assembly process.

[0071] Furthermore, the slot 250 has an opening 260 on the side near the push rod 140, the opening 260 extending radially along the push rod 140 to the slot of the slot 250, the opening 260 being used to avoid the push rod 140.

[0072] Understandably, the opening 260 provides clearance for the push rod 140, ensuring that the slot 250 fits into the first pressing member 230 so that the second pressing member 240 can avoid the push rod 140 and prevent interference between the second pressing member 240 and the push rod 140.

[0073] In some specific embodiments, a retaining strip 270 is provided on the side of the second pressing member 240 near the opening of the slot 250. One end of the retaining strip 270 is connected to the second pressing member 240, and a protrusion 280 is provided on one side of the retaining strip 270. The protrusion 280 abuts and limits the first pressing member 230 near the edge of the slot 250.

[0074] Understandably, the protrusion 280 on the clip 270 forms a mechanical stop on the edge of the first pressing member 230, which can resist the accidental disengagement of the second pressing member 240 caused by vibration. In addition, after the clip 270 is elastically deformed by external force, it can drive the protrusion 280 to contact the limiting position of the first pressing member 230, which makes it convenient to insert the first pressing member 230 into the slot 250 or remove the first pressing member 230 from the slot 250.
