Description
Technical Field
[0001] This utility model belongs to the technical field of glue nail dispensers, and relates to a glue nail dispenser that facilitates the disassembly of the gun needle. Background Technology
[0002] Adhesive tag dispensers, also known as tag guns, can be used to secure hang tags. They can be used to specifically secure items such as quilts, for example, to keep the quilt insert and cover in place, effectively preventing the quilt insert from shifting during use and improving the user experience.
[0003] Currently, a patent for a tag gun has been published in Chinese patent literature (authorization announcement number CN104608975B). This tag gun, to a certain extent, meets the needs of usage scenarios such as fixing tags. It uses a pin-type connector to send a needle. The pin has a groove; when the groove aligns with the needle, the pin will not compress the needle, allowing it to be pulled out. Rotating the pin shifts the groove away from the needle, causing the ungrooved part of the pin to compress the needle for fixation. However, in actual operation, because it is difficult to precisely align the groove with the needle when rotating the pin, it easily leads to difficulties in disassembling the needle. This not only reduces efficiency but also causes considerable inconvenience to users. Summary of the Invention

[0030] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of this utility model easier to understand and master. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0031] This embodiment provides a glue nail dispenser, such as Figure 1-8 As shown, the device includes a housing 100, on which a gun needle 200 and a rotatable needle lock 800 are provided. The needle lock 800 has a groove 811. When the needle lock 800 is in the unlocked position, and the groove 811 is aligned with the gun needle 200, the gun needle 200 can be disassembled. A limiting structure is provided between the needle lock 800 and the housing 100. The limiting structure includes an unlocking limiting part 171. When the needle lock 800 is in the unlocked position, the unlocking limiting part 171 prevents the needle lock 800 from rotating in a first direction.
[0032] A limiting structure, including an unlocking limiting part 171, is added between the pin lock 800 and the housing 100. When the pin lock 800 rotates to the unlocked position and the groove 811 aligns with the gun needle 200, the unlocking limiting part 171 immediately activates, mechanically preventing the pin lock 800 from rotating in the first direction. The principle is to use the limiting structure to create a stable unlocked state, physically restricting the pin lock 800 from rotating further in the first direction until it reaches the unlocked position, thus ensuring precise alignment between the groove 811 and the gun needle 200. Users no longer need to repeatedly try to adjust the position of the groove 811 and the gun needle 200; with the groove 811 aligned with the gun needle 200, the pin lock 800 will not exert significant pressure on the gun needle 200, allowing for easy removal of the gun needle 200. This not only significantly simplifies the operation process and improves the efficiency of removing the gun needle 200, but also reduces the user's operational difficulty, greatly improving the user experience of the glue pin dispenser and making the product more practical and competitive in the market.
[0033] like Figure 4-6 As shown, the unlocking limiting part 171 is a support platform located on the housing 100. The limiting structure also includes a blocking part 830 located on the needle lock 800. When the needle lock 800 is in the unlocked position, the blocking part 830 abuts against the unlocking limiting part 171. Through the mutual abutment and cooperation of the support platform and the blocking part 830, a physical limiting barrier is constructed. When the needle lock 800 rotates to the unlocked position and the groove 811 aligns with the gun needle 200, the blocking part 830 on the needle lock 800 rotates accordingly to contact and abut against the support platform on the housing 100. Utilizing the rigid support of the support platform, the rotation of the needle lock 800 in the first direction is restricted, ensuring that the groove 811 is stably aligned with the gun needle 200. In other optional embodiments, the operating handle can also directly abut against the unlocking limiting part 171.
[0034] In other optional embodiments, the housing 100 is provided with an arc-shaped hole, the unlocking limiting part 171 is located at one end of the arc-shaped hole, and the limiting structure further includes a limiting pin fixed on the pin lock 800. The limiting pin is inserted in the arc-shaped hole, and when the pin lock 800 is in the unlocked position, the limiting pin abuts against the unlocking limiting part 171.
[0035] like Figure 6 As shown, the pin lock 800 includes a locking pin 810 inserted into the housing 100 and an operating handle connected to the end of the locking pin 810. A blocking portion 830 connects both the locking pin 810 and the operating handle. The locking pin 810 is cylindrical, and a groove 811 is located on the locking pin 810. This improves the connection strength between the locking pin 810, the operating handle, and the blocking portion 830. In other alternative embodiments, the blocking portion 830 can also be directly connected to either the operating handle or the locking pin 810.
[0036] like Figure 4 , 5 As shown, the housing 100 has a locking and limiting part 172. When the pin lock 800 is in the locked position, the blocking part 830 abuts against the locking and limiting part 172. This allows the pin lock 800 to have a larger unlocking angle when it is in the locked position, preventing the glue pin dispenser from automatically unlocking during use.
[0037] Specifically, the side wall of the housing 100 has a semi-circular annular rib 170. The unlocking limit part 171 and the locking limit part 172 are located at the two ends of the rib 170, respectively. The needle lock 800 rotates 180 degrees from the unlocked position to the locked position. The unlocking limit part 171 and the locking limit part 172 at both ends of the semi-circular annular rib 170 provide clear start and stop points for the rotation of the needle lock 800. When the needle lock 800 is in the unlocked position, the blocking part 830 on the needle lock 800 abuts against the unlocking limit part 171, restricting the needle lock 800 from rotating in the first direction and ensuring that the groove 811 is stably aligned with the needle 200; while when the needle lock 800 is rotated 180 degrees to the locked position, the blocking part 830 abuts against the locking limit part 172, so that the needle lock 800 remains stable in that position. In this way, the pin lock 800 has a large rotation angle from the locked position to the unlocked position, which effectively prevents the pin lock 800 from being accidentally rotated and automatically unlocked due to slight shaking, external impact or other factors during use of the glue nail dispenser.
[0038] like Figure 3 As shown, the gun needle 200 includes a needle head 210 and an elastic sleeve 220 fixed to one end of the needle head 210. When the needle lock 800 is in the locked position, the needle lock 800 compresses the elastic sleeve 220. The elastic deformation characteristics of the elastic sleeve 220 are used to achieve stable fixation of the gun needle 200. When the needle lock 800 is rotated to the locked position, the needle lock 800 contacts the elastic sleeve 220 and applies pressure. The elastic sleeve 220 deforms under force, tightly fitting the needle lock 800 and the internal structure of the housing 100, thereby firmly fixing the gun needle 200 in the working position and ensuring that the gun needle 200 will not loosen or shift during the use of the glue nail dispenser. When it is necessary to disassemble the gun needle 200, the needle lock 800 is rotated to the unlocked position. At this time, the needle lock 800 no longer compresses the elastic sleeve 220, the elastic sleeve 220 returns to its original shape, the gun needle 200 is freed from external force restraint, and the user can easily disassemble it. In other alternative embodiments, the needle 200 may not have the elastic sleeve 220. When the needle lock 800 is in the locked position, a portion of the needle lock 800 is embedded in the limiting groove of the upper limit groove of the needle 200.
[0039] like Figure 1-4As shown, a storage box 500 is detachably fixed to the top of the housing 100. The storage box 500 has a receiving cavity, and a cover 510 is provided at the opening of the receiving cavity. The storage box 500 can be used to store accessories such as glue needles and fixing buckles. Both sides of the housing 100 are provided with an upper limit strip 111 and a lower limit strip 112. A sliding groove 110 is formed between the upper limit strip 111 and the lower limit strip 112. The length of the upper limit strip 111 is less than the length of the lower limit strip 112. The portion of the lower limit strip 112 that protrudes from the upper limit strip 111 is provided with a slot 113. The storage box 500 is provided with a sliding part 520 that is embedded in the sliding groove 110. The sliding part 520 is provided with a locking part 521 that is locked onto the slot 113.
[0040] Furthermore, the storage box 500 has a downwardly extending extension 530 at its rear end, which abuts against the rear end of the housing 100. A connecting portion 531 is fixed to the lower end of the extension 530. A slot 120 is provided on the housing 100, and one end of the connecting portion 531 is inserted into the slot 120 and engaged with the housing 100. The height of the slot 120 is greater than the thickness of the connecting portion 531. This improves the stability of the connection of the storage box 500.
[0041] like Figure 1-3 As shown in Figures 7 and 8, a needle sleeve 600 is fitted onto the gun needle 200. The needle sleeve 600 has a fixing part 610, and the housing 100 has a fixing groove 130 with an opening facing the side. The fixing part 610 is embedded in the fixing groove 130. The needle sleeve 600 can protect the gun needle 200 and prevent the gun needle 200 from injuring people. The cooperation between the fixing part 610 and the fixing groove 130 can prevent the needle sleeve 600 from falling off accidentally, improve the stability of the needle sleeve 600, and thus improve safety.
[0042] like Figure 4 , 7As shown, the housing 100 includes a first housing 140 and a second housing 150. The housing 100 includes a handle 160, which has multiple mounting slots 161. Anti-slip strips 162 are mounted on the mounting slots 161. Each mounting slot 161 has a fixing hole located at one end of the first housing 140 and the second housing 150, respectively. The anti-slip strips 162 are embedded in the mounting slots 161, and both ends of the anti-slip strips 162 are fixed at the fixing holes. The anti-slip strips 162 can be made of silicone. The presence of the anti-slip strips 162 greatly increases the friction on the surface of the handle 160, allowing the user to firmly grip the handle 160 even when their hands are sweaty or in a slippery environment, preventing the handle 160 from slipping and affecting the accuracy of operation or causing accidents. The anti-slip strips 162 span between the first housing 140 and the second housing 150, improving the stability of the connection between the first housing 140 and the second housing 150.
[0043] like Figure 3 As shown, the housing 100 is provided with an operating component 400 and a ejector pin 300. A slider 310 is provided inside the housing 100. The ejector pin 300 is fixed to the slider 310. A drive rod 410 is hinged to the slider 310. The lower end of the drive rod 410 has an elongated hole 411. The operating component 400 has a drive post 420 passing through the elongated hole 411. A first linkage rod 430 is hinged to the middle of the drive rod 410. The end of the first linkage rod 430 away from the drive rod 410 is hinged to the housing 100 via a hinge shaft 450. A second linkage rod 440 is also hinged at the hinge shaft 450. The operating component... A plug-in block 470 is rotatably mounted on component 400. The second linkage rod 440 can move through the plug-in block 470 relative to it. A return component 460 is sleeved on the second linkage rod 440. When the operating component 400 is pressed, the drive column 420 moves within the elongated hole 411, pushing the drive rod 410 to rotate. The drive rod 410 drives the slider 310 and the ejector pin 300 to move forward, thus realizing the working action of the ejector pin 300. After the operating component 400 is released, the elastic force of the return component 460 causes the second linkage rod 440 to drive the drive rod 410 and other components to reset, and the ejector pin 300 also returns to its initial position. The return component 460 is a spring.
[0044] like Figure 3As shown, a transmission bar 710 is slidably disposed within the housing 100, and an actuating member 700 is rotatably disposed within the housing 100. The transmission bar 710 and the actuating member 700 are connected by a connecting rod 720. The front end of the transmission bar 710 is provided with a return post 711, and the rear end of the transmission bar 710 is provided with an actuating post 712. The upper end of the drive rod 410 is located between the return post 711 and the actuating post 712. When the operating member 400 is pressed, the upper end of the drive rod 410 swings forward, which pushes the return post 711 to move the transmission bar 710 forward, and the actuating member 700 rotates clockwise relative to the housing 100. When the operating member 400 is released, the upper end of the drive rod 410 swings backward, which pushes the actuating post 712 to move the transmission bar 710 backward, and the actuating member 700 rotates counterclockwise relative to the housing 100. The actuating member 700 moves the rubber pin downward for use in the next fixing operation.
