Description

Technical Field

[0001] This utility model relates to the field of hinges for furniture, and more specifically to a pin hinge adapted for installation on the aluminum frame of a cabinet side panel. Background Technology

[0002] Currently, in existing pin hinge technology, the fixed component is located on the cabinet body, while the movable component is located on the door frame. The door frame is made of aluminum profile, and the fixed and movable components are hinged through the hinge axis of the pin hinge. Some new furniture designs also incorporate a structure combining an aluminum frame with a glass panel (or plastic panel, etc.) in the cabinet body, either partially or entirely. The aluminum frame surrounds the outside of the glass panel, thus the cabinet side panels also have aluminum frames. Some cabinet side panels have relatively small aluminum frames in the front-to-back direction (e.g., 25 mm). However, the fixed component of traditional pin hinges is designed for installation on cabinet side panels made of wood, such as the "Pin Hinge with a Reinforced and Stable Structure" in Chinese Utility Model Patent Publication No. CN217631892U. This structure is not specifically designed for aluminum frames and is therefore unsuitable for installation on the aluminum frames of cabinet side panels. Therefore, it is necessary to develop a pin hinge that is suitable for installation on the aluminum frames of cabinet side panels. Summary of the Invention

Detailed Implementation

[0024] The present invention will now be further described with reference to the accompanying drawings.

[0025] The pin hinge of this utility model, such as Figures 1 to 3 As shown, it includes a fixed component 1, a hinge shaft 2, and a movable component 3. The fixed component 1 is connected to the movable component 3 through the hinge shaft 2. The fixed component 1 is located on the aluminum frame 99 of the cabinet side panel, and the movable component 3 is located on the door frame 98. Thus, the door frame 98 can swing horizontally around the hinge shaft 2.

[0026] like Figures 2 to 5 As shown, the fixing assembly 1 includes a mounting base 10, a hinge arm 11, a slide 12, a front-to-back adjusting eccentric shaft 13, a vertical adjusting eccentric shaft 14, a left-to-right adjusting screw 15, and a tightening screw 16. The vertical adjusting eccentric shaft 14 is located above the front-to-back adjusting eccentric shaft 13, and the left-to-right adjusting screw 15 is located above the vertical adjusting eccentric shaft 14. Thus, the front-to-back adjusting eccentric shaft 13, the vertical adjusting eccentric shaft 14, and the left-to-right adjusting screw 15 are arranged approximately along a vertical straight line. The tightening screw 16 is located behind the left-to-right adjusting screw 15. Figure 6 As shown, the mounting base 10 has a forward-opening insertion cavity 100. The slide 12 is adapted to slide back and forth within the insertion cavity 100. In other words, during assembly, the slide 12 is inserted into the insertion cavity 100 from front to back. Figure 2 and Figure 4As shown, a plate portion 110 is formed at the rear of the hinge arm 11. The rear end of the plate portion 110 is connected to the slide block 12 via a vertically arranged hinge pin 111. That is to say, the hinge arm 11 can be horizontally swung relative to the slide block 12 around the hinge pin 111 for adjustment. Figure 1 Combination Figure 4 As shown, the hinge pin 111 is located on the rear side of the tightening screw 16. The tightening screw 16 is set at the same height as the left and right adjusting screws 15, that is, the tightening screw 16 is located directly behind the left and right adjusting screws 15; Figures 6 to 8 As shown, the mounting base 10 has an inner plate 102 formed on one side of the insertion cavity 100. In other words, the inner plate 102 helps to form the insertion cavity 100. In practical applications, the inner plate 102 is concealed within the aluminum frame 99 of the cabinet side panel, such as... Figure 3 and Figure 7 As shown, the upper part of the inner plate 102 has an upper baffle portion 1021 for abutting the upper end of the slide block 12, the lower part of the inner plate 102 has a lower baffle portion 1022 for abutting the lower end of the slide block 12, and the inner plate 102 has a connecting plate portion 1020 for abutting the middle part (in the vertical direction) of the slide block 12, as shown. Figure 8 As shown, the lower baffle portion 1022 and the upper baffle portion 1021 are connected as one unit by the connecting plate portion 1020, as... Figure 3 and Figure 8 As shown, the connecting plate portion 1020 is provided with a clearance hole 1023 for avoiding the front and rear adjustment eccentric shaft 13.

[0027] like Figure 1 and Figure 2As shown, since the front-to-back adjusting eccentric shaft 13, the up-to-down adjusting eccentric shaft 14, and the left-to-right adjusting screws 15 are arranged approximately along a vertical straight line, it is beneficial to make the mounting base 10 structurally compact in the front-to-back direction, that is, to reduce the size of the mounting base 10 in the front-to-back direction, so that the mounting base 10 can be adapted to the narrower aluminum frame 99 of the cabinet side panel. Due to the reduced size of the mounting base 10 in the front-to-back direction, the depth of the cavity 100 in the front-to-back direction is also reduced accordingly. Furthermore, by setting the connecting plate portion 1020 to abut against the middle of the slide 12, this utility model further enhances the positioning and guiding function of the mounting base 10 on the slide 12. By setting the lower baffle portion 1022 and the upper baffle portion 1021 to be connected as one piece by the connecting plate portion 1020, the structural strength of the inner plate 102 is greatly increased, which can avoid the elasticity of the inner plate 102. The plastic deformation further enhances the positioning and guiding effect of the mounting base 10 on the slide 12, that is, it can avoid the reduction of the linear guiding performance of the slide 2 due to the reduction of the depth dimension of the insertion cavity 100, and thus avoid the wobbling of the hinge arm 11 in use. By setting the clearance hole 1023, the installation of the front and rear adjustment eccentric shaft 13 is not affected by the addition of the connecting plate part 1020. Since the tightening screw 16 and the left and right adjustment screws 15 are set at the same height, and the tightening screw 16 is located between the left and right adjustment screws 15 and the hinge pin 111, the distances from the tightening screw 16 to the hinge pin 111 and from the tightening screw 16 to the left and right adjustment screws 15 are both short. Therefore, when the tightening screw 16 is tightened, the elastic bending deformation of the insertion plate part 110 can be reduced, so that the thrust generated by the tightening screw 16 can be more effectively transmitted to the left and right adjustment screws 15 and the hinge pin 111. As can be seen from the above, the structure of the fixing component 1 is reasonably adjusted so that the pin hinge of the present invention can be installed on the aluminum frame of the cabinet side panel. Of course, the pin hinge of the present invention can also be installed on traditional wooden cabinets, so the pin hinge of the present invention has a wide range of applications.

[0028] Furthermore, such as Figures 6 to 8 As shown, the mounting base 10 has a vertically arranged panel 101, such as Figure 1 Combination Figure 2 As shown, panel 101 is used to abut against the inner side (in the left-right direction) of the aluminum frame 99 of the cabinet side panel, and screw mounting holes are formed at the top and bottom ends of panel 101 respectively; as Figures 6 to 8 As shown, the insertion cavity 100 is formed between the front panel 101 and the inner panel 102, so the insertion cavity 100 is embedded in the aluminum frame 99 of the cabinet side panel. A rotating support shell 103 is formed at the lower part of the insertion cavity 100, as shown. Figure 2 and Figure 4As shown, one end of the front-to-back adjusting eccentric shaft 13 is rotatably connected to the rotating support housing 103. Specifically, a circular hole is formed inside the rotating support housing 103, and the front-to-back adjusting eccentric shaft 13 is rotatably connected to the aforementioned circular hole. Figures 6 to 8 As shown, the mounting base 10 forms a cavity top plate 105 at the top of the cavity 100, and a cavity bottom plate 106 at the bottom of the cavity 100. A guide groove 104 is formed between the rotating support shell 103 and the inner plate 102. Figure 9 As shown, the slide block 12 comprises a vertical slide plate 121, a top plate 122, and an ear plate 123. The upper end of the vertical slide plate 121 is integrally connected to one end of the top plate 122, and the ear plate 123 is integrally connected to the vertical slide plate 121. The ear plate 123 and the top plate 122 can be formed by a bending process. The ear plate 123 is located below the top plate 122. Figure 7 As shown, the top plate 122 is adapted to be disposed between the front panel 101 and the inner plate 102, thus positioning the slide block 12 in the left-right direction of the insertion cavity 100. The vertical slide plate 121 is attached to the inner plate 102 and is adapted to be disposed between the bottom plate 106 and the top plate 105 of the insertion cavity, thus positioning the slide block 12 in the up-down direction of the insertion cavity 100; Figures 3 to 5 As shown, the insertion plate portion 110 is disposed between the top plate 122 and the ear plate 123. The top plate 122 and the ear plate 123 are respectively connected to the upper and lower ends of the hinge pin 111. In other words, the upper end of the hinge pin 111 is adapted to pass through the top plate 122, and the lower end of the hinge pin 111 is adapted to pass through the ear plate 123. That is to say, the insertion plate portion 110 is located within the insertion cavity 100. Figure 3 and Figure 7 As shown, the lower end of the vertical slide plate 121 is adapted to slide within the guide groove 104, so the guide groove 104 positions the lower end of the vertical slide plate 121 in the left and right directions; the above arrangement makes the internal structure of the insertion cavity 100 linearly guide the slide block 12 with high rigidity.

[0029] Furthermore, such as Figure 7 As shown, the ear plate 123 is attached to the upper side of the rotating support shell 103. In other words, a horizontal support surface is formed on the upper side of the rotating support shell 103, and the ear plate 123 is attached to the above-mentioned horizontal support surface. Thus, the rotating support shell 103 guides the ear plate 123.

[0030] Furthermore, such as Figure 1 Combination Figure 2As shown, the fixing component 1 is provided with a decorative cover plate 18, which covers the outer side of the panel 101 (the "outer side" here refers to the inner panel 102, that is, the inner panel 102 is located inside the panel 101). In the front-back direction, the decorative cover plate 18 is set with the same width as the aluminum frame 99 of the cabinet side panel. By setting the decorative cover plate 18 to cover the mounting base 10, it is beneficial to make the fixing component 1 have a simple visual effect that matches the aluminum frame 99 of the cabinet side panel, thereby improving the visual effect of the cabinet interior.

[0031] Furthermore, such as Figure 11 As shown, the decorative cover plate 18 has a back insert post 181, that is, the back insert post 181 is formed on the back side of the decorative cover plate 18, as... Figure 8 As shown, the upper and lower ends of the panel 101 are respectively provided with insertion mounting holes 107, such as... Figure 2 As shown, each of the socket mounting holes 107 is provided with a resilient socket 17, such as... Figure 3 As shown, the back insert 181 is inserted into the corresponding elastic sleeve 17. When the back insert 181 is inserted into the elastic sleeve 17, the back insert 181 slightly squeezes and expands the elastic sleeve 17, causing the elastic sleeve 17 to elastically deform and open slightly. The elastic restoring force of the elastic sleeve 17 clamps the back insert 181, thereby fixing the decorative cover plate 18. The elastic sleeve 17 can be made of rubber, and the decorative cover plate 18 can be an injection molded part.

[0032] Furthermore, such as Figure 8 As shown, an inner protruding ring 1071 is formed on the inner wall of the socket mounting hole 107, such as... Figure 10 As shown, an annular groove 171 is formed on the outer side of the elastic sleeve 17, and an inner convex ring 1071 is adapted to be disposed in the annular groove 171. Therefore, during the installation of the elastic sleeve 17, the elastic sleeve 17 is pressed into the sleeve mounting hole 107, and one end of the elastic sleeve 17 elastically deforms past the inner convex ring 1071, so that the annular groove 171 reaches the position of the inner convex ring 1071, and the aforementioned one end of the elastic sleeve 17 elastically resets. The installation of the elastic sleeve 17 is completed, and the inner convex ring 1071 axially positions the elastic sleeve 17, preventing the elastic sleeve 17 from dislodging from the sleeve mounting hole 107 when the back insert post 181 is inserted into or removed from the elastic sleeve 17.

[0033] like Figures 2 to 5As shown, one end of the front-to-back adjusting eccentric shaft 13 is rotatably connected to the rotating support housing 103, and the corresponding other end of the front-to-back adjusting eccentric shaft 13 is located in the elongated hole extending in the vertical direction of the slide block 12. Thus, rotating the front-to-back adjusting eccentric shaft 13 can drive the slide block 12 to move back and forth for adjustment. One end of the vertical adjusting eccentric shaft 14 is located in the elongated hole extending in the vertical direction of the insert plate portion 110, and the corresponding other end of the vertical adjusting eccentric shaft 14 is rotatably connected to the slide block 12. Thus, rotating the vertical adjusting eccentric shaft 14 can drive the hinge arm 11 to slide up and down relative to the slide block 12 along the hinge pin 111 for adjustment. The left-to-right adjusting screw 15 is rotatably connected to the slide block 12, and the end of the left-to-right adjusting screw 15 is engaged with the slide block 12, so that the left-to-right adjusting screw 15 can be adjusted. Rotating the slide block 12 does not allow the left-right adjusting screw 15 to move axially relative to the slide block 12 significantly. The left-right adjusting screw 15 is screwed onto the insert plate 110. Rotating the left-right adjusting screw 15 allows the hinge arm 11 to swing horizontally around the hinge pin 111 for adjustment. This horizontal swing of the hinge arm 11 allows the door frame 98 to be adjusted left and right. The tightening screw 16 is screwed onto the insert plate 110, with its end abutting against the vertical slide plate 121. Tightening the tightening screw 16 pushes the insert plate 110 away from the vertical slide plate 121, causing the hinge pin 111 to press tightly against the insert plate 110 and the slide block 12, and the left-right adjusting screw 15 to press tightly against the slide block 12 and the insert plate 110, thus eliminating any looseness between the hinge arm 11 and the slide block 12. Figure 3 As shown, the other end of the aforementioned front and rear adjusting eccentric shaft 13 is located within the range of the clearance hole 1023.
