Description

Technical Field

[0001] This utility model relates to the field of hinges, specifically to a pin hinge with a damping seat quick-release structure. Background Technology

[0002] Currently, pin hinges are commonly used in aluminum-framed doors. A pin hinge includes a fixed mounting base, a hinge arm, a hinge shaft, and a moving component. The fixed mounting base is fixed to the inner panel of the cabinet with screws. The hinge arm is installed on the fixed mounting base via an adjustment mechanism. The hinge arm connects to the moving component via the hinge shaft. The aluminum-framed door includes an aluminum frame and a glass panel. The aluminum frame surrounds the outer perimeter of the glass panel. The moving component needs to be installed on the aluminum frame. Because the moving component includes a damper, which is installed on the moving seat of the moving component, the moving seat is also called a "damping seat," as illustrated in Chinese Utility Model Patent Publication No. CN222084290U, "A Pin Hinge with a Built-in Moving Seat." The movable seat includes a plug and a mounting ear plate. The mounting ear plate has screw mounting holes, and screws are installed in the screw mounting holes. The screws are screwed into the aluminum frame strip, thereby positioning the movable seat on the aluminum frame strip. Since the mounting screws need to be drilled and tapped in the aluminum frame, more tools are required to install the pin hinge, and the installation process is complicated and inconvenient. If self-tapping screws are used, it will result in high physical labor intensity and long installation time. Moreover, the aluminum frame needs to be extruded and formed with internal teeth, which will result in high production cost of the aluminum frame. The screw connection structure also makes the disassembly process inconvenient, and frequent screw installation and removal will easily lead to thread wear. Therefore, the existing damping seat and aluminum frame mounting structure needs to be improved. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pin hinge with a damping seat quick-release structure, which facilitates the quick assembly and disassembly of the moving components of the pin hinge.

[0004] The objective of this utility model is achieved through the following technical solution.

[0005] This utility model discloses a pin hinge with a quick-release structure for a damping seat, comprising a hinge arm and a movable assembly. The movable assembly includes a damping seat for mounting on a door frame. One end of the hinge arm is connected to the damping seat via a hinge shaft. The rear portion of the damping seat forms a plug for insertion into a slot in the door frame. The movable assembly includes a latching assembly, which includes a latching arm, a driving block, and a push pin. The latching arm is slidably connected to the plug. One end of the latching arm forms a latching portion for latching onto the rear side of the slot edge. The front portion of the push pin is screwed to the damping seat, and the rear portion of the push pin is connected to the driving block. The inner side of the latching arm forms a push-receiving inclined surface. The driving block forms a driving inclined surface for abutting and pushing the push-receiving inclined surface to extend the latching portion outward. The latching assembly includes a return spring for driving the latching arm to retract inward. One end of the return spring is connected to the corresponding other end of the latching arm.

[0006] Preferably, the buckle arm has a clamping ramp for contacting the inner corner of the socket, the clamping ramp being located on the inner side of the buckle portion.

[0007] Preferably, the push pin has an annular groove, and the drive block has a snap fastener that engages with the annular groove.

[0008] Preferably, the fastening assembly includes a plug, which is inserted into the insert and forms a receiving cavity. The return spring is disposed in the receiving cavity, and the fastening arm forms a barb post, which is disposed in the end of the return spring.

[0009] Preferably, the front of the damping seat has a frame cover for covering the mounting groove of the door frame, and the frame cover has a screw hole, the front of the push pin is connected to the screw hole.

[0010] Compared with the prior art, the advantages of this utility model are as follows: by setting a plug block for insertion into the door frame through the rear part of the damping seat, the movable component includes a fastening component, which includes a fastening arm, a driving block and a push pin. One end of the fastening arm has a fastening part for fastening to the rear side of the edge of the door frame. The front part of the push pin is screwed to the damping seat, and the rear part of the push pin is connected to the driving block. The inner side of the fastening arm has a pushing slope, and the driving block has a driving slope for abutting and pushing the pushing slope to make the fastening part extend outward.

Detailed Implementation

[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] This utility model relates to a pin hinge with a damping seat quick-release structure, such as... Figures 1 to 3 As shown, it includes a hinge arm 2 and a movable component 3, such as Figure 1 As shown, the left end of the hinge arm 2 is connected to the fixed mounting base 1, as follows: Figures 1 to 3 As shown, the movable component 3 includes a damping seat 31 for mounting on the door frame 98, and one end of the hinge arm 2 is connected to the damping seat 31 via a hinge shaft 4, as shown. Figures 5 to 7 As shown, the rear part of the damping seat 31 has a plug 312 for insertion into the socket 811 of the door frame 98, such as... Figure 2 As shown, the door frame 98 is made of aluminum profile, and the door frame 98 forms a main cavity 80. The socket 811 connects to the main cavity 80, so the plug 312 is inserted into the main cavity 80; as Figure 2 and Figure 3 As shown, the movable component 3 includes a fastening component 33, which includes a fastening arm 331, a driving block 332, and a push pin 333. The fastening arm 331 is slidably connected to the insert block 312. Specifically, the insert block 312 forms a groove 3121, and the fastening arm 331 is slidably disposed within the corresponding groove 3121. Figure 8 As shown, one end of the buckle arm 331 has a buckle portion 3311 for fastening to the rear side of the insertion edge portion 8111, as shown. Figure 3 As shown, the front of the push pin 333 is screwed to the damping seat 31, and the rear of the push pin 333 is connected to the drive block 332, as shown. Figure 6 and Figure 8 As shown, a push-receiving inclined surface 3310 is formed on the inner side of the buckle arm 331, such as... Figure 9 As shown, the drive block 332 is formed with a drive ramp 3321 for abutting against and pushing the push ramp 3310 to cause the latch 3311 to extend outward, as shown. Figure 3 As shown, the fastening assembly 33 includes a return spring 336 for driving the buckle arm 331 to retract and move inward. One end of the return spring 336 is connected to the corresponding other end of the buckle arm 331, and the drive block 332 is configured to slide back and forth.

[0024] During the installation of the movable component 3 onto the door frame 8, the insert 312 is inserted rearward into the socket 811. Then, the push pin 333 is rotated, causing it to move rearward. The push pin 333 drives the drive block 332 to move rearward, thus pushing the drive ramp 3321 outward against the push ramp 3310, causing the latch arm 331 to move outward. In other words, the insert 312 guides the latch arm 331 in the vertical direction, causing the latch part 3311 to move outward and protrude from the insert 312. Figure 3 and Figure 4As shown, the latch 3311 moves to the rear side of the insertion edge 8111. The rear of the insertion edge 8111 is actually the inner wall of the main cavity 80. At this time, when the movable component 3 is moved forward relative to the door frame 8, the insertion edge 8111 blocks the latch 3311, thus the latch 3311 engages with the insertion edge 8111. Since the insertion block 312 is adapted to be inserted into the insertion port 811, the movable component 3 is positioned by the insertion port 811 in both the left-right and up-down directions, making... The active component 3 and the door frame 8 are positioned and installed. In order to make it easy for the drive inclined surface 3321 to push the latch arm 331, the angle between the sliding direction of the push inclined surface 3310 and the latch arm 331 is greater than 45° (preferably about 60°). If the angle between the push inclined surface 3310 and the sliding direction of the latch arm 331 is too small, the outward component of the force exerted by the drive block 332 on the latch arm 331 will be insufficient. When the latch arm 331 moves outward, the latch arm 331 causes the return spring 336 to deform elastically. When it is necessary to disassemble the movable component 3, the push pin 333 is rotated in the opposite direction, causing the push pin 333 to move forward. The push pin 333 drives the drive block 332 to move forward, and the drive inclined surface 3321 moves away from the pushed inclined surface 3310. The elastic restoring force of the return spring 336 pushes the latch arm 331 inward, so the latch part 3311 retracts into the range of the insertion port 811. By moving the movable component 3 forward by hand, the movable component 3 can be completely separated from the door frame 8. It can be seen that the movable component 3 is easy to install and disassemble. As can be seen from the above, this utility model uses the spiral motion of the push pin 333 to drive the latch part 3311 to latch the edge part of the insertion port 8111 and to drive the latch part 3311 to unlock from the edge part of the insertion port 8111. This avoids the need to process threaded holes or form an internal toothed structure on the door frame 8. By setting the latching component 33, it is beneficial to quickly install and disassemble the movable component 3 of the pin hinge, and it is also beneficial to repeatedly install and disassemble the movable component 3, which also helps to reduce the labor intensity of on-site installation of pin hinges.

[0025] Furthermore, such as Figure 8 As shown, the buckle arm 331 has a clamping ramp 3312 for contacting the inner corner of the socket 811. The clamping ramp 3312 is located on the inner side of the buckle portion 3311, and the outer end of the clamping ramp 3312 is integrally connected to the inner end of the buckle portion 3311. The clamping ramp 3312 extends obliquely forward relative to the buckle portion 3311, as shown. Figure 4As shown, since the clamping ramp 3312 is located inside the buckle 3311, when the buckle arm 331 moves outward, the buckle 3311 first moves to the rear side of the insertion edge 8111, and then the clamping ramp 3312 contacts the inner corner of the insertion 811. Tightening the push pin 333 causes the clamping ramp 3312 to push forward against the inner corner of the insertion 811. Conversely, the front part of the damping seat 31 (specifically the frame cover 311) presses backward against the bottom of the mounting groove 81 of the door frame 8, thus clamping the insertion edge 8111 between the front part of the damping seat 31 and the clamping ramp 3312. This further stabilizes the damping seat 31 and the door frame 8. Because the screw connection between the push pin 333 and the damping seat 31 creates a self-locking effect, it prevents the damping seat 31 from easily loosening. Figure 3 As shown, the movable component 3 includes a damper 32, the cylinder of which is inserted into the damping seat 31. The fastening components 33 are symmetrically distributed on both sides of the damper 32. Thus, when the fastening arm 331 located in the upper position moves outward, it moves upward, and when the fastening arm 331 located in the lower position moves outward, it moves downward. The reaction force of the lower end of the insertion port 811 on the upward fastening arm 331 is supported by the upper end of the insertion port 811.

[0026] Furthermore, such as Figure 9 As shown, the push pin 333 has an annular groove 3331, and the drive block 332 has a latch 3322. The latch 3322 latches onto the annular groove 3331, so the bottom of the annular groove 3331 is adapted to be located between the upper edge and the lower edge of the latch 3322, thereby positioning the push pin 333 and the drive block 332 relative to each other in the axial direction of the push pin 333. Moreover, the push pin 333 and the drive block 332 are also relatively positioned in the vertical direction. Specifically, the push pin 333 slides into the latch 3322 in the left-right direction. By setting the connection structure of the latch 3322 latching onto the annular groove 3331, the push pin 333 and the drive block 332 have a floating gap between them, which is beneficial to improve the assembly tolerance and can reduce the manufacturing precision requirements of the damping seat 31, the drive block 332 and the push pin 333.

[0027] Furthermore, such as Figure 5 and Figure 6 As shown, the fastening assembly 33 includes a plug 334, which is inserted into the insert block 312. Specifically, the insert block 312 forms a slot 3122 and a sliding groove 3121. The slot 3122 communicates with the sliding groove 3121, and the fastening arm 331 is slidably disposed within the sliding groove 3121. Figure 10 As shown, the plug 334 forms a receiving cavity 3340, such as Figure 3 As shown, the return spring 336 is disposed within the receiving cavity 3340, as... Figure 8 As shown, the buckle arm 331 has a barbed post 3313, as... Figure 3As shown, the barb post 3313 is located inside the end of the return spring 336, so the return spring 336 is a compression spring. During the assembly process, the assembly of push pin 333 and drive block 332 is first placed into the slide groove 3121. Then, the push pin 333 is rotated to move forward by screwing the push pin 333 into the damping seat 31. Then, the latch arm 331 is inserted into the plug block 334 in the vertical direction. Then, the return spring 336 is installed into the receiving cavity 3340 through the opening 3341 of the receiving cavity 3340, so that the return spring 336 is shortened elastically. The inner end of the return spring 336 can be fitted onto the barb post 3313. The magnet 34 is inserted into the bottom of the slot 3122 from back to front. Then, the plug block 334 is inserted forward into the slot 3122 while the latch arm 331 is inserted into the slide groove 3121. Then, the rivet 335 is installed. The rivet 335 passes through the plug block 334 and the damping seat 31 in the left and right direction. By setting the plug 334 to accommodate the return spring 336, the internal structure of the damping seat 31 can be simplified, making the damping seat 31 relatively easier to manufacture. The plug 334 acts as a sliding guide for the latch arm 331, preventing the inner end of the latch arm 331 from shifting back and forth relative to the damping seat 31.

[0028] Furthermore, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the front of the damping seat 31 has a frame cover 311 for covering the mounting groove 81 of the door frame 98. The insertion port 811 is opened at the bottom of the mounting groove 81 and connects to the main cavity 80. The frame cover 311 includes a horizontal plate and a vertical plate. The vertical plate is located between the upper and lower horizontal plates. The upper and lower ends of the hinge shaft 4 are respectively connected to the horizontal plates. The horizontal plates are respectively attached to the upper and lower inner side walls of the mounting groove 81. The vertical plate is attached to the front side of the bottom of the mounting groove 81, thus avoiding the mounting groove 81 from being exposed to people's view, which is beneficial to the aesthetics of the aluminum frame door. The front end of the insertion block 312 is integrally connected to the back of the vertical plate. A screw hole 3101 is formed on the frame cover 311 (the screw hole 3101 passes through the insertion block 312 to the rear). Specifically, the screw hole 3101 is formed on the aforementioned vertical plate. Figure 3 As shown, the front part of the push pin 333 is connected to the screw hole 3101, and the front end of the push pin 333 has a cross groove, so the push pin 333 can be rotated by using a screwdriver on the front side of the damping seat 31.
