Description

Technical Field

[0001] This utility model relates to the technical field of sofa cover elastic band threading devices, specifically a sofa cover elastic band installation threading device. Background Technology

[0002] In the furniture manufacturing industry, the installation of elastic bands on sofa covers is a key process to ensure the fit and comfort of the sofa. With the increasing use of pleats and three-dimensional tailoring elements in modern sofa designs, the traditional method of manually threading elastic bands can no longer meet the needs of large-scale production, which has led to the development of technology for elastic band installation threading devices for sofa covers.

[0003] Because sofa cover fabrics are often made of elastic and textured materials such as cotton, linen, and velvet, and the fabric piled up in the folds forms irregular channels, the front guide structure of the threader often has difficulty accurately capturing the entrance of the fabric path. At the same time, during the threading process, the elastic resistance and fiber friction of the folded fabric can cause the threader to be obstructed, and the operator needs to continuously apply a large pushing force, which can easily cause the elastic band to shift and the fabric to wear out. It can also prolong the assembly time of a single sofa set due to repeated adjustments. Utility Model Content

[0004] The purpose of this utility model is to provide a sofa cover elastic band installation guide, which has the advantages of fast and stable operation of sofa cover elastic band installation. It solves the problem of low assembly efficiency of sofa cover elastic bands in the prior art, because the guide is difficult to capture and push when passing through wrinkled sofa fabric.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A sofa cover elastic band installation guide includes an installation guide assembly and a magnetic suction cup assembly. The installation guide assembly includes an installation head; a magnetic suction plate is provided at the upper end of the installation head, and the magnetic suction plate is integrally formed with the installation head; a connecting sleeve is provided at one end of the installation head, and the connecting sleeve is integrally formed with the installation head; a connector is provided inside the connecting sleeve, and the connector is rotatably connected to the inner wall of the connecting sleeve; an elastic band placement groove is provided at one end of the connector, and the elastic band placement groove is integrally formed with the connector; a pressing splicing strip is provided at the upper end of the elastic band placement groove; a splitting strip is provided at one end of the pressing splicing strip; the magnetic suction cup assembly includes a handle; a tray is provided at the lower end of the handle; and a magnetic block is provided at the center of the lower end of the tray.

[0006] Preferably, the magnetic block is provided with support columns on all four sides, and the support columns are fixedly connected to the tray.

[0007] It is worth noting that the support pillars and ball bearings are used to support the fabric under the tray, improving the flatness of the fabric.

[0008] Preferably, the lower end of the support column is provided with ball bearings, and the ball bearings are connected and rolled inside the support column.

[0009] It is worth noting that: the combination of the support column and the rolling support of the ball effectively improves the flatness of the sofa fabric, further improves the smoothness of the dragging when the guide head and the magnetic block are magnetically attracted, and reduces dragging resistance.

[0010] Preferably, the magnetic block and the magnetic plate are magnetically connected.

[0011] It is worth noting that the magnetic attraction between the magnetic block and the magnetic plate is used to pull the threading device assembly.

[0012] Preferably, the elastic band is placed inside the elastic band placement slot.

[0013] It is worth noting that the inside of the elastic band placement groove is used to fix one end of the elastic band, thereby improving the stability of the elastic band during threading.

[0014] Preferably, the pressing splicing strip is spliced ​​and connected to the elastic band placement groove.

[0015] It is worth noting that the connection method between the pressure splicing strip and the elastic band placement groove greatly improves the ease of installation of the elastic band.

[0016] Preferably, the splitting strip and the pressing splicing strip are integrally formed.

[0017] It is worth noting that the split strip design facilitates the assembly and disassembly of the pressure splice strip, improving the ease of installation of the elastic band.

[0018] Preferably, both the elastic band placement groove and the pressing splice strip are made of soft rubber material.

[0019] It is worth noting that the soft material of the elastic band placement groove and the pressure splice strip prevents the threader assembly from getting stuck in the holes when passing through them.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses an elastic band placement slot to hold the elastic band, and then uses a pressing splicing strip to press the elastic band down and splice it with the elastic band placement slot to fix it, thereby achieving the function of fixing one end of the elastic band. Then, the entire threading device assembly is inserted into the elastic band sleeve of the sofa cover. After that, the handle is held and the magnetic block is brought close to the threading head. Due to the magnetic attraction between the threading head and the magnetic block, when the handle is dragged, the magnetic plate is attracted and dragged by the magnetic block, thereby completing the dragging and threading function of the elastic band, which greatly improves the efficiency of threading the elastic band of the sofa cover.

[0021] With the tray, support column, and ball bearings, the tray effectively peels away wrinkles from the sofa fabric during gripping and dragging, allowing the wrinkles to be evenly pushed aside and preventing fabric buildup from affecting the efficiency of the elastic band. Combined with the rolling support of the support column and ball bearings, the flatness of the sofa fabric is effectively improved, further enhancing the smoothness of dragging after the threading head and magnetic block are magnetically attracted, and reducing dragging resistance.
