Description

Technical Field

[0001] This utility model relates to the field of furniture processing technology, and in particular to an improved handle-free profile. Background Technology

[0002] Handleless cabinets are a type of profile installed on the front edge of cabinets and base cabinets. They form a recessed space along the top edge of the cabinet body, behind the cabinet door, allowing a hand to reach in and pull the door open. Currently, the common installation method for handleless profiles involves inserting a fastener into a mounting groove on the back of the profile, securing the groove and fastener with bolts, and then fixing the fastener to the cabinet panel with screws. This connection method has a drawback: frequent opening and closing of the cabinet doors causes vibrations. Since the handleless profile and fastener are bolted together, over time, the vibrations can cause the bolts to loosen, leading to the handleless profile becoming loose or falling off.

[0003] A handle-free mounting component for an L-shaped cabinet door, disclosed in Chinese Utility Model Patent Application Publication CN215993287U, includes a fixing component and an L-shaped handle detachably connected to the fixing component. The fixing component and the L-shaped handle are respectively bonded with buckles. To improve the bonding effect of the buckles, the fixing component has a first positioning groove, and the L-shaped handle has a second positioning groove. The buckles are fixed in the first and second positioning grooves with glue and / or adhesive backing. Multiple sets of mushroom-shaped protrusions are fixedly connected to the other side of the buckles, and these protrusions interlock. The connection between the fixing component and the L-shaped handle is achieved through bonding and the interlocking of the mushroom protrusions. However, frequent opening and closing of the cabinet can cause the glue or adhesive backing to loosen, and over time, its bonding strength weakens, eventually leading to the L-shaped handle loosening or even falling off. To address this issue, we propose an improved handle-free profile installation structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes an improved handle-free profile.

[0005] It solves the problem of handle-free profiles becoming loose due to prolonged use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an improved handle-free profile, comprising a handle-free profile body, a fixing component, and a spring piece. The handle-free profile body has a mounting groove extending along its length on its back. The fixing component includes a slider and a mounting ear. The slider is perpendicularly connected to the mounting ear and slidably connected to the mounting groove. A threaded hole is provided through the middle of the slider, and a bolt is threaded into the threaded hole. The mounting ear has a screw hole. The spring piece is movably installed inside the mounting groove. The spring piece is arched, with the arched top abutting against the bottom of the slider. A hanging component is provided on the side of the spring piece, with one end fixedly connected to the side of the spring piece and the other end movably connected to the wing at the top of the mounting groove.

[0007] Furthermore, the mounting groove has a rectangular cross-section, and a wing extending towards the center is provided at the top of the mounting groove.

[0008] Furthermore, grooves are provided on the opposite sides of the slider, and the size of the grooves matches the size of the wing at the top of the mounting groove.

[0009] Furthermore, the cross-section of the hanger is arched.

[0010] Furthermore, the mounting ear surface is provided with at least two screw holes.

[0011] Compared with the prior art, this utility model has the following advantages: This installation structure utilizes the pre-tightening force and buffering effect of the spring and the hanging parts to effectively offset the impact of cabinet vibration on the connection structure, prevent the bolts from loosening due to long-term vibration, and ensure the overall stability of the installation through the rigid connection of the screws, thereby significantly reducing the risk of loosening or falling off of the handle-free profile during long-term use.

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] Reference Figure 1-2As shown, an improved handle-free profile includes a handle-free profile body 1, a fixing member 2, and a spring piece 6. The handle-free profile body 1 has a mounting groove 3 extending along its length on its back. The mounting groove 3 has a rectangular cross-section, and a wing 8 extending towards the center is provided at the top of the mounting groove 3. The fixing member 2 includes a slider 21 and a mounting ear 22. The slider 21 is perpendicularly connected to the mounting ear 22. Grooves 9 are formed on two opposite sides of the slider 21, and the size of the grooves 9 matches the size of the wing 8 at the top of the mounting groove 3. The slider 21 is slidably connected to the mounting groove 3. A threaded hole 4 is provided through the middle of the slider 21, and a bolt 5 is threadedly connected to the threaded hole 4. The spring piece 6 is movably installed within the mounting groove 3. The spring piece 6 is arched, and the top of the arch of the spring piece 6 abuts against the bottom of the slider 21. When the bolt 5 on the slider 21 is tightened, the end of the bolt 5 presses against the top of the spring piece 6, and at the same time the spring piece 6 gives the bolt 5 an outward pushing force, so that the slider 21 and the mounting groove 3 form a firm connection. The mounting ear 22 is provided with screw holes 10 for fixing the handle-free profile body 1 to the side wall of the cabinet. A hanging piece 7 is provided on the side of the spring piece 6. The hanging piece 7 is arched. One end of the hanging piece 7 is fixedly connected to the side of the spring piece 6, and the other end of the hanging piece 7 is movably connected to the wing 8 at the top of the mounting groove 3. During the installation process, the arch of the hanging piece 7 abuts against the side wall of the cabinet to ensure that the handle-free profile body 1 will not move horizontally after installation.

[0017] During installation, first align the slider 21 of the fixing component 2 with the mounting groove 3 on the back of the handle-free profile body 1, and ensure that the groove 9 on the side of the slider 21 matches the wing 8 at the top of the mounting groove 3. Then, smoothly push the slider 21 along the length of the mounting groove 3 until it moves to the vicinity of the preset installation position on the side wall of the cabinet. Next, place the spring piece 6 inside the mounting groove 3 with its arch facing upwards, and ensure that one end of the hanging piece 7 on the side of the spring piece 6 is movably connected to the wing 8 at the top of the mounting groove 3. After that, place the handle-free profile body 1, along with the installed fixing component 2 and spring piece 6, close to the side wall of the cabinet. At this time, the arch of the hanging piece 7 will naturally abut against the side wall of the cabinet, initially restricting the horizontal movement of the handle-free profile body 1. Then, use screws to pre-fix the mounting ear 22 to the side wall of the cabinet through the screw holes 10 on the surface of the mounting ear 22, ensuring that the handle-free profile body 1 will not easily fall off. Finally, use a tool to tighten the bolt 5 that runs through the middle of the slider 21. As the bolt 5 is screwed in, the end of the bolt 5 gradually presses against the dome of the spring 6. The spring 6 undergoes elastic deformation under force, and at the same time, it gives the bolt 5 an outward thrust. This thrust causes the slider 21 to fit tightly against the wing 8 and the wall of the mounting groove 3, thus forming a firm connection between the slider 21 and the mounting groove 3. This further strengthens the fixing effect between the handle-free profile body 1 and the cabinet side wall, effectively preventing the handle-free profile body 1 from loosening or moving horizontally after installation. This installation structure utilizes the pre-tightening force and buffering effect of the spring 6 and the hanger 7 to effectively offset the impact of cabinet vibration on the connection structure, prevent the bolt 5 from loosening due to long-term vibration, and ensure the overall stability of the installation through the rigid connection of the screws. This significantly reduces the risk of the handle-free profile body 1 loosening or falling off during long-term use.
