Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive tools, and in particular to a hot melt adhesive stick pushing structure, and also to a hot melt adhesive pen using the structure. Background Technology

[0002] Hot melt glue pens are hot melt glue devices with a pen-shaped design. They are compact, lightweight, and easy to carry. They are comfortable to hold and flexible to operate, making them especially suitable for repairing furniture, making handicrafts, and engaging in parent-child DIY activities. They have become an indispensable tool in daily life and work.

[0003] To achieve the dispensing of hot melt glue sticks, a glue cavity and a corresponding dispensing structure are provided inside the hot melt glue pen. For example, the technical solution described in patent document No. 202122874090.5, entitled "A Wireless Lithium-ion Mini Hot Melt Glue Pen," involves placing the glue stick and then pushing the push handle to move the push rod synchronously, thus dispensing the hot melt glue stick. However, this method has the following main problems:

[0004] First, when using it, the thumb needs to work with the other fingers to hold the hot glue pen while pushing the handle forward, which requires the thumb to apply force in at least two directions, making it relatively strenuous and inconvenient to use.

[0005] Second, because the glue stick is installed close to the pen tip and a power supply component is required on its rear side, the length of the glue stick used is greatly limited. Currently, it can generally only be used with short glue sticks of 7×20mm, resulting in short glue supply of hot melt glue pen, frequent glue replenishment, and inability to use long glue sticks. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a hot melt glue stick pushing structure that is easy and labor-saving to operate, can be used with a long glue stick, can effectively extend the glue supply, and significantly reduce the frequency of glue replenishment.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is: a hot melt glue stick pushing structure, used on a hot melt glue pen and surrounding the outer periphery of the hot melt glue stick, including a glue stick enclosure, a glue stick pushing seat fixedly connected to one side of the glue stick enclosure, a pushing button movably configured with the glue stick pushing seat, a pushing and clamping device rotatably assembled inside the glue stick enclosure, and part of the pushing and clamping device extending to the outside of the glue stick enclosure.

[0008] As a preferred technical solution, the glue rod surround is configured as a U-shaped arc plate surrounding the outer periphery of the hot melt glue rod, and the pushing and clamping device is located between the two straight sections of the U-shaped arc plate.

[0009] As a preferred technical solution, the two straight plate sides of the U-shaped arc plate are fixedly connected to limit baffles, and a clearance hole is provided through the limit baffles. The pushing and clamping device is provided through the clearance hole.

[0010] As a preferred technical solution, the pushing and clamping device includes a glue stick clamping plate that is gradually arranged from top to bottom toward the hot melt glue stick. The upper end of the glue stick clamping plate is connected to a clamping drive roller that abuts against the surface of the hot melt glue stick. The clamping drive roller is rotatably disposed inside the U-shaped arc plate. The glue stick clamping plate is also provided with a glue stick release pull plate that extends to the outside of the glue stick enclosure, and a release tension spring is connected to the glue stick release pull plate.

[0011] As a preferred technical solution, the two ends of the release spring are respectively equipped with spring hanging shafts, and the two spring hanging shafts are arranged vertically, with the upper spring hanging shaft fixedly installed and the lower spring hanging shaft fixed to the rubber rod release plate.

[0012] As a preferred technical solution, the side of the glue stick clamping plate facing the hot melt glue stick is configured with an arc surface structure.

[0013] As a preferred technical solution, the glue rod pusher includes a pusher body, and pusher guide slides are respectively provided on both sides of the pusher body, and the pusher guide slides are inclined outward from the glue rod enclosure.

[0014] As a preferred technical solution, each side of the pusher body is provided with at least two pusher guide slides.

[0015] As an improvement to the above technical solution, the push button includes a button body that is covered and fastened to the end of the rubber rod push seat, and the inner wall of the button body is provided with a push claw that is correspondingly abutted against the push guide slide.

[0016] This utility model also relates to a hot melt glue pen, including a hot melt glue pen body, an end of which is connected to a melting structure, and the aforementioned hot melt glue stick pushing structure. The glue stick surround, the glue stick pushing seat, and the pushing and holding device are all disposed in the hot melt glue pen body. Part of the pushing button is exposed outside the hot melt glue pen body, and a surround return spring is installed between the glue stick surround and the melting structure to limit the movement.

[0017] Due to the adoption of the above technical solution, this utility model has the following beneficial effects: When in use, pressing the push button causes it to slide against the glue stick pusher, forcing the glue stick pusher to drive the glue stick enclosure and the push clamping device to move downwards synchronously. At the beginning of the downward movement, the friction between the hot melt glue stick and the push clamping device causes the push clamping device to rotate and clamp the hot melt glue stick, thus driving it downwards synchronously until it reaches the downward limit position of the glue stick pusher to complete one push of the hot melt glue stick. Releasing the press of the push button automatically releases the grip on the hot melt glue stick and returns it to its original position. Pressing the push button again will continue to push the hot melt glue stick. The entire process can be completed by pressing the push button with the thumb, which is convenient and labor-saving. Moreover, the length of the hot melt glue stick is not limited and can be extended to the outer end of the hot melt glue pen, effectively extending its glue supply and significantly reducing the frequency of glue replenishment.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0029] like Figures 1 to 7 As shown, the hot melt glue stick pushing structure is installed inside the hot melt glue pen and surrounds the outer periphery of the hot melt glue stick 1. It is used to push the hot melt glue stick 1 outward. Specifically, it includes a glue stick surround plate 2, which is configured as a U-shaped arc plate surrounding the outer periphery of the hot melt glue stick 1. That is, it is composed of two straight plate parts arranged opposite and parallel to each other and an arc plate part connecting the two straight plate parts. The glue stick surround plate 2 becomes the connecting base component of all parts of the entire structure.

[0030] In this embodiment, a glue stick pusher is fixedly connected to one side of the glue stick enclosure 2. A push button is movably mounted on the glue stick pusher. In use, pressing the push button with the thumb forcibly pushes the glue stick pusher to move, generating the power to push out the hot melt glue stick 1. A push-holding device is rotatably mounted inside the glue stick enclosure 2, and part of the push-holding device extends to the outside of the glue stick enclosure 2. Specifically, the push-holding device is located between the two straight sections of the U-shaped arc plate. The push-holding device holds the hot melt glue stick 1 tightly when pushing it, and automatically releases and returns the hot melt glue stick 1 to its original position when it is pushed to the limit position, completing one push of the hot melt glue stick 1.

[0031] The pushing and clamping device includes a glue stick clamping plate 3 that is gradually arranged from top to bottom toward the hot melt glue stick 1. The upper end of the glue stick clamping plate 3 is connected to a clamping drive roller 4 that abuts against the surface of the hot melt glue stick 1. The clamping drive roller 4 is rotatably disposed inside the U-shaped arc plate via a rotating shaft. The glue stick clamping plate 3 is also provided with a glue stick release pull plate 5 that extends to the outside of the glue stick surrounding plate 2. A release tension spring 6 is connected to the glue stick release pull plate 5. When the push button is used to move the glue stick pusher downwards, the clamping drive roller 4 will move downwards synchronously under the connection of the glue stick enclosure 2 and the rotating shaft. However, due to its tight contact with the hot melt glue stick 1, there will be a large friction between them. Under the action of friction, the clamping drive roller 4 will rotate at a certain angle, and the release spring 6 will be stretched, causing the lower end of the glue stick clamping plate 3 to move towards the hot melt glue stick 1 until it is close to it and clamps it. The tight cooperation between the clamping drive roller 4 and the hot melt glue stick 1 drives the hot melt glue stick 1 to move downwards synchronously, thereby realizing the push of the hot melt glue stick 1. When the glue stick pusher reaches the limit position, the press of the push button is released, the release spring 6 retracts, and at the same time, the glue stick release pull plate 5 will drive the glue stick clamping plate 3 back to its original position, so that the lower end of the glue stick clamping plate 3 separates from the hot melt glue stick 1, realizing the push and release of the hot melt glue stick 1.

[0032] In this embodiment, tension spring hanging shafts 7 are respectively provided at both ends of the release tension spring 6, and the two tension spring hanging shafts 7 are arranged vertically. The upper tension spring hanging shaft 7 can be fixedly installed on the inner wall of the hot melt glue pen, and the lower tension spring hanging shaft 7 is fixed to the glue stick release pull plate 5, thereby realizing the hanging of the tension spring hanging shafts 7. The glue stick clamping plate 3 is set with an arc surface structure on the side facing the hot melt glue stick 1, forming a line contact with the hot melt glue stick 1, so that the hot melt glue stick 1 is locally compressed, thereby improving the clamping effect.

[0033] Limiting baffles 8 are fixedly connected to the two straight plate side edges of the U-shaped arc plate. A clearance hole 9 is provided through the limiting baffle 8, and the pushing and clamping device is disposed through the clearance hole 9. The limiting baffle 8 limits the pushing and clamping device. In fact, the glue stick release pull plate 5 is disposed through the clearance hole 9 to facilitate assembly with the release spring 6. Furthermore, the limiting baffle 8 limits the glue stick release pull plate 5 to prevent its lower end from being too far from the hot melt glue stick 1 under the tension of the release spring 6, thereby ensuring that the clamping drive roller 4 can clamp the hot melt glue stick 1 with a small rotation angle.

[0034] The glue stick pusher includes a pusher body 10, with push guide slides 11 on both sides of the pusher body 10. The push guide slides 11 are inclined outward from the glue stick enclosure 2 to cooperate with the push button, converting the vertical pressing force on the push button into downward force, thereby pushing the pusher body 10 downward. Each side of the pusher body 10 has at least two push guide slides 11, making the force on the pusher body 10 more even and stable.

[0035] The push button includes a button body 12 that covers the end of the push rod base. The inner wall of the button body 12 is provided with push claws 13 that abut against the push guide slide 11. In this embodiment, the push guide slide 11 is configured as a protrusion protruding from the surface of the push base body 10, and the push claws 13 abut against the corresponding protrusion surface to achieve a sliding engagement between them. In practice, the push guide slide 11 can also be configured as a groove structure, in which case the push claws 13 can be confined within the corresponding groove.

[0036] like Figure 8 As shown, this embodiment also relates to a hot melt glue pen, including a hot melt glue pen body 14, with a melting structure 15 connected to the end of the hot melt glue pen body 14, and also including the aforementioned hot melt glue stick pushing structure. The glue stick enclosure 2, the glue stick pushing seat, and the pushing and holding device are all disposed inside the hot melt glue pen body 14. The pushing button is plugged into and limitedly mounted on the hot melt glue pen body 14, with part of the pushing button exposed outside the hot melt glue pen body 14. A enclosure return spring 16 is installed between the glue stick enclosure 2 and the melting structure 15 for limiting the movement. The hot melt glue pen body 14 and the melting structure 15 are well known to those skilled in the art and will not be described in detail here.

[0037] In use, pressing the push button forces the glue stick pusher seat to move downwards. During the downward movement of the glue stick pusher seat, the hot melt glue stick 1 is gripped by the push clamping device until the glue stick pusher seat reaches its downward limit position. Then, the press of the push button is released, and the push clamping device releases its grip on the hot melt glue stick 1, completing one push. At this time, under the elastic force of the retaining plate return spring 16, the glue stick pusher seat automatically returns to its original position to prepare for the next push task.

[0038] In this embodiment, the hot melt glue stick 1 can be pushed out by simply pressing the push button. The force application process is more in line with the thumb's movement habits, making operation convenient and effortless. Through the reasonable design of the cooperation between the push button and the glue stick push base, this embodiment can push glue about 5mm with a single press, which is more in line with the amount of glue used in daily life. The hot melt glue stick push structure has a small installation space, making it suitable for use with various mini and small hot melt glue pens. It also has few restrictions on the hot melt glue stick 1, and is compatible with standard length 7×150mm hot melt glue sticks 1, solving the shortcomings of traditional hot melt glue pens that have short glue supply and require frequent glue stick replacements.

[0039] The description of this utility model is given for illustrative and descriptive purposes only, and is not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
