Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging box technology, and in particular to a handle installation device for cardboard packaging boxes. Background Technology
[0002] Cardboard boxes are widely used in many industries for packaging food, beverages, daily necessities, and electronic products. For example, in the food industry, handles on packaging boxes for pastries and biscuits make it easier for consumers to carry the purchased goods; in the electronics industry, handles on packaging boxes for products such as mobile phones and tablets help facilitate handling during transportation and sales.
[0003] Traditional methods for installing handles on cardboard packaging boxes are often quite complex, typically requiring the use of screws, glue, and other auxiliary materials. For example, when using screws to install handles, holes need to be pre-drilled in both the box and the handle before the screws are passed through and tightened. This process is not only cumbersome but also requires tools such as screwdrivers. If glue is used to attach the handles, the amount of glue applied and the placement of the glue need to be precisely controlled, and the handles need to be secured before the glue dries to prevent them from shifting. This not only increases the difficulty and time cost of installation but also, if not done properly, can lead to the handles not being securely installed. This complexity results in low installation efficiency, especially in large-scale packaging box production, which can seriously affect production schedules. Utility Model Content

[0006] The locking mechanism includes a positioning post, and a recycling groove is provided on both sides of the surface of the positioning post. A return spring is fixedly connected to the inner wall of the recycling groove. A locking buckle is fixedly connected to the surface of the return spring. A sleeve is locked to the surface of the locking buckle. A locking groove is provided on the surface of the sleeve. An insertion groove is provided inside the sleeve.
[0007] The above technical solution makes handle installation simple and convenient, allowing personnel to quickly install handles onto the packaging box lid, thus improving assembly efficiency.
[0008] As a further improvement to the above solution, the positioning post is fixedly connected to the inner wall of the embedding groove.
[0009] The above technical solution ensures the stability of the locking mechanism during handle installation, making the connection between the handle and the packaging box lid more secure and reliable, and reducing the possibility of the handle loosening or falling off during use.
[0010] As a further improvement to the above solution, the locking buckle is adapted to the locking groove, and the insertion groove is adapted to the positioning post.
[0011] The above technical solution and the compatible structure ensure the accuracy and stability of the handle installation process, enabling the handle to be installed firmly.
[0012] As a further improvement to the above solution, the handle is fixedly connected to the surface of the sleeve.
[0013] As a further improvement to the above solution, tamping rods are fixedly connected to both sides of the inner wall of the embedding groove, and mounting grooves are opened on both sides of the sleeve.
[0014] As a further improvement to the above solution, a second reset spring is fixedly connected to the inner wall of the mounting groove, and a contact ring is fixedly connected to the bottom end of the second reset spring.
[0015] Through the above technical solution, the cooperation between the tamping rod and the mounting groove and other structures plays an auxiliary role in the installation process, ensuring that the handle is installed in place.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0027] Example:
[0028] Please combine Figure 1-5 This embodiment of a cardboard packaging box handle installation device includes a packaging box body 1. Packaging cover plates 8 are hinged to both sides of the upper surface of the packaging box body 1. An embedding groove 2 is opened on the surface of the packaging cover plate 8. A snap-fit mechanism 3 is provided inside the embedding groove 2. The packaging cover plate 8 is snapped with a handle 9 through the snap-fit mechanism 3.
[0029] The locking mechanism 3 includes a positioning post 301. Both sides of the positioning post 301 have a recovery groove 302. A return spring 303 is fixedly connected to the inner wall of the recovery groove 302. A locking buckle 304 is fixedly connected to the surface of the return spring 303. A sleeve 305 is locked to the surface of the locking buckle 304. A locking groove 306 is formed on the surface of the sleeve 305, and an insertion groove 307 is formed inside the sleeve 305. The sleeve 305 below the handle 9 is inserted into the positioning post. At position 301, the positioning pin 301 enters the insertion groove 307 of the sleeve 305. During this process, the inner wall of the insertion groove 307 presses against the locking buckle 304, and the locking buckle 304 compresses the return spring 303 and is stored in the recycling groove 302. When the positioning pin 301 and the insertion groove 307 are installed in place, the locking groove 306 is located on one side of the locking buckle 304. The return spring 303 resets, causing the locking buckle 304 to insert into the locking groove 306, thus achieving the snap-fit between the handle 9 and the packaging cover 8.
[0030] The positioning post 301 is fixedly connected to the inner wall of the embedded groove 2, which provides a stable foundation for the handle 9 to be engaged with the positioning post 301 through the sleeve 305.
[0031] The locking buckle 304 is adapted to the locking groove 306, and the insertion groove 307 is adapted to the positioning pin 301. When the positioning pin 301 and the insertion groove 307 are installed in place, the return spring 303 returns to its original position and pushes the locking buckle 304 to insert into the locking groove 306, forming a stable engagement. The adaptation of the insertion groove 307 and the positioning pin 301 ensures that the positioning pin 301 can be smoothly inserted into the sleeve 305 during installation, and that the locking buckle 304 can be triggered to engage after installation.
[0032] The handle 9 is fixedly connected to the surface of the sleeve 305. When the sleeve 305 and the positioning post 301 are engaged, the handle 9 can be fixed to the packaging box cover as the sleeve 305 is installed.
[0033] Both sides of the inner wall of the embedded groove 2 are fixedly connected with tamping rods 4, and both sides of the sleeve 305 are provided with mounting grooves 5.
[0034] A second return spring 6 is fixedly connected to the inner wall of the mounting groove 5, and a contact ring 7 is fixedly connected to the bottom end of the second return spring 6. During the installation of the handle, the tamping rod 4 is inserted into the mounting groove 5 on both sides of the sleeve 305. As the sleeve 305 descends, the tamping rod 4 compresses the second return spring 6 through the contact ring 7. After the handle is installed, the tamping rod 4 continues to compress the second return spring 6, causing it to store elastic potential energy. When the handle is disassembled, when the locking buckle 304 is pressed to unlock, the second return spring 6 begins to reset, pushing the contact ring 7 downward and causing the sleeve 305 to move upward and disengage from the positioning post 301.
[0035] The tamping rod 4 comes into contact with the contact ring 7.
[0036] The implementation principle of the cardboard packaging box handle installation device in this application embodiment is as follows: During installation, the operator aligns the part of the handle 9 with the sleeve 305 below it with the positioning post 301 embedded in the groove 2 on the surface of the packaging cover 8, and then begins to insert the sleeve 305 into the positioning post 301. At this time, the positioning post 301 will enter the insertion groove 307 inside the sleeve 305. During the insertion process, the inner wall of the insertion groove 307 will press the locking buckle 304 in the recovery groove 302 on both sides of the surface of the positioning post 301, and the locking buckle 304 is subjected to... After pressure is applied, the return spring 303 is compressed and stored inside the recycling groove 302. When the positioning post 301 and the insertion groove 307 are installed in place, the locking groove 306 on the surface of the sleeve 305 is located on one side of the locking buckle 304. Due to the reset action of the return spring 303, the locking buckle 304 will insert into the locking groove 306, thereby realizing the snap-fit between the handle 9 and the packaging cover 8 through the snap-fit mechanism 3, and installing the handle onto the packaging cover 8. During this process, the tamping rods fixedly connected to both sides of the inner wall of the embedded groove 2 are... As the sleeve 305 descends, rod 4 inserts into the mounting grooves 5 on both sides of the sleeve 305. When rod 4 is inserted into the mounting groove 5, it compresses the second return spring 6 through the contact ring 7 at the bottom of the inner wall of the mounting groove 5. After the handle is installed, rod 4 continues to compress the second return spring 6, causing it to store elastic potential energy. When disassembly is required, personnel press the locking buckle 304 in the recovery groove 302 on both sides of the surface of the positioning post 301, causing the locking buckle 304 to compress the first return spring 303 and be stored inside the recovery groove 302, thus releasing the tension. The locking relationship between the sleeve 305 and the positioning post 301 is such that when the locking buckle 304 is pressed to unlock, the return spring 6 is stored in elastic potential energy due to the compression of the push rod 4 when the handle was installed. At this time, the return spring 6 begins to reset and pushes the contact ring 7 to move downward. The downward movement of the contact ring 7 will drive the sleeve 305 to move upward, so that the sleeve 305 can quickly detach from the surface of the positioning post 301, thereby completing the removal of the handle 9 from the packaging cover 8.
[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
