Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically a quick-assembly type silent and unobstructed hinge. Background Technology

[0002] A hinge is a mechanical device used to connect two solids and allow relative rotation between them. Hinges can be made of movable components or foldable materials. Hinges are mostly installed on cabinets. According to the material, they are mainly divided into stainless steel hinges and iron hinges. To provide people with a better experience, hydraulic hinges (also known as damping hinges) have emerged. Their feature is that they provide a buffer function when the cabinet door is closed, minimizing the noise caused by the cabinet door colliding with the cabinet body when it closes.

[0003] Patent CN218934135U discloses a hinge, comprising: a stationary hinge with a first mounting cylinder on its side, the end of which has a limiting groove; a movable hinge with a second mounting cylinder on its side, the end of which has a limiting boss; and a damping structure, one end of which passes through the inner cavity of the first mounting cylinder and the other end of which passes through the inner cavity of the second mounting cylinder; wherein the limiting boss is circumferentially movable about the damping structure as an axis along the limiting groove. When the movable hinge flips relative to the stationary hinge about the damping structure as an axis, it drives the limiting boss to move circumferentially along the limiting groove. When the limiting boss abuts against the end of the limiting groove, the movable hinge cannot continue to flip in the same circumferential direction. By reducing the maximum flipping angle of the movable hinge, the damping structure is reduced from rotating to its limit state, thereby protecting the damping structure.

[0004] Based on existing solutions and actual use, the current hinges still have some problems, such as: when installing the hinges, due to the need for multiple positioning steps and inaccurate pre-drilled holes, it is difficult to align them, making it difficult to make fine adjustments after installation. If the hole position is off, it is necessary to re-drill holes, which increases the rework rate and installation time, and makes it easy to loosen during long-term use, affecting the overall stability and sealing. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-assembly silent and unobstructed hinge to solve the problems mentioned in the background art, which are currently difficult to align due to the need for multi-step positioning and inaccurate pre-drilled holes, making fine-tuning difficult after installation, thus increasing rework rate and installation time, and making it easy to loosen during long-term use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly type silent and unobstructed hinge, comprising:

[0007] A stationary hinge is provided, with a movable hinge rotatably connected to its right end. Mounting plates are fixedly installed on both the stationary and movable hinges. Slide grooves are provided at both the upper and lower ends of the mounting plate, and mounting components are provided in the slide grooves. Adjustment components are provided on the left and right sides of the slide grooves. An injection component is provided at the top of the stationary hinge.

[0008] Preferably, the mounting assembly includes a sliding block, a rotating sleeve, and a first screw, and the sliding block is slidably connected to the groove of the slide, the rotating sleeve is rotatably connected to the inside of the sliding block, and the first screw is threadedly connected to the inside of the rotating sleeve.

[0009] Preferably, the adjustment assembly includes a hinge frame, a limiting rod, a sliding rod, and a positioning hole. Sliding rods are provided on both the left and right sides of the slide groove, and positioning holes are arrayed at both the upper and lower ends of the sliding rods. The hinge frame is rotatably connected to the outer side of the rotating sleeve, and the hinge frame is slidably connected to the sliding rod. Limiting rods are inserted at both the left and right ends of the front end of the hinge frame, and the rods of the limiting rods are engaged with the positioning holes.

[0010] Preferably, a second screw is threadedly connected to the ring of the hinge frame, and the shank of the second screw is threadedly connected to the rotating sleeve.

[0011] Preferably, the injection assembly includes an oil tank, a push rod, a piston, an oil outlet pipe, and a guide groove. The oil tank is fixedly installed on the top of the stationary hinge. The push rod is slidably connected to the left end of the oil tank. The piston is fixedly installed on the end of the push rod inside the oil tank. The oil outlet pipe is fixedly installed on the right end of the oil tank. The guide groove is provided on the top of the stationary hinge.

[0012] Preferably, the oil outlet pipe and the guide groove are configured in a corresponding state, and the connection between the guide groove and the static hinge and the dynamic hinge is configured in a corresponding state, and the diameter of the piston is consistent with the diameter of the inner cavity of the oil tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This quick-assembly silent and unobstructed hinge can quickly connect the first screw to the pre-installed hole by rotating the rotating sleeve, so that installation can be completed without complicated tools, thereby reducing installation time. Then, by adjusting the position of the first screw, it can cover a wider range of hole spacing, without the need to re-drill holes or replace the hinge, and shorten the debugging time, ensuring that the ideal gap and closing force are achieved when closed. Then, by pushing the piston, it can avoid damping instability or self-closing force reduction caused by dryness, thereby maintaining a longer silent effect and improving the user experience.

[0014] 1. The device is equipped with a sliding block, a rotating sleeve, a first screw, and a second screw. By tightening the second screw, the fixing between the hinge frame and the rotating sleeve can be released. Then, the first screw is pressed and the rotating sleeve is rotated, causing the rotating sleeve to rotate inside the sliding block. The rotation of the rotating sleeve causes the first screw to extend and retract, which in turn connects to the pre-drilled hole, allowing for the installation of the stationary and moving hinges. The rotation of the rotating sleeve enables the quick connection between the first screw and the pre-drilled hole, allowing installation to be completed without complicated tools. This not only facilitates installation but also makes subsequent disassembly or replacement of parts easier, thereby reducing installation time.

[0015] 2. The device is equipped with a sliding groove, a sliding block, a rotating sleeve, a first screw, a hinge frame, a limiting rod, a sliding rod, and a positioning hole. By pulling the limiting rod out of the positioning hole, the fixing between the sliding rod and the hinge frame can be released. Then, the hinge frame can be pushed so that it slides on the body of the sliding rod, and the sliding block drives the first screw to slide in the groove of the sliding groove. This allows the position of the first screw to be adjusted so that it is aligned with the pre-drilled hole position. By adjusting the position of the first screw, a wider range of hole spacing can be covered. Thus, by adjusting the first screw, errors can be quickly corrected without re-drilling or replacing the hinge, shortening the debugging time and ensuring that the ideal gap and closing force are achieved when closing.

[0016] 3. It is equipped with a stationary hinge, oil reservoir, push rod, piston, oil outlet pipe, and guide groove. The oil outlet pipe and guide groove are set in a corresponding state, and the guide groove is set in a corresponding state at the connection between the stationary hinge and the moving hinge. By pushing the push rod, the push rod drives the piston to slide in the inner cavity of the oil reservoir. The movement of the piston drives the movement of the lubricating oil in the oil reservoir, which flows into the groove of the guide groove through the oil outlet pipe and into the connection between the stationary hinge and the moving hinge through the guide groove, thus lubricating the stationary hinge and the moving hinge. Pushing the piston can avoid damping instability or reduction of self-closing force caused by dryness, thereby maintaining a quiet effect for a longer time and improving the user experience.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a quick-assembly silent and unobstructed hinge, comprising: a static hinge 1, a moving hinge 2, a mounting plate 3, a sliding groove 4, a sliding block 5, a rotating sleeve 6, a first screw 7, a hinge frame 8, a second screw 9, a limiting rod 10, a sliding rod 11, a positioning hole 12, an oil tank 13, a push rod 14, a piston 15, an oil outlet pipe 16, and a guide groove 17.

[0026] First, as attached Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 5As shown, when the stationary hinge 1 and the movable hinge 2 are installed, the first screw 7 can be adjusted according to the hole position of the specified installation position. Then, the mounting plate 3 is fixedly installed on both the stationary hinge 1 and the movable hinge 2. The upper and lower ends of the mounting plate 3 are provided with sliding grooves 4, and the sliding block 5 is slidably connected in the groove of the sliding plate 4. The sliding sleeve 6 is rotatably connected inside the sliding block 5. The sliding rod 11 is also provided on the left and right sides of the groove of the sliding plate 4. The upper and lower ends of the sliding rod 11 are provided with positioning holes 12 in an array. At the same time, the hinge frame 8 is rotatably connected to the outside of the rotating sleeve 6, and the hinge frame 8 is slidably connected to the rod of the sliding rod 11. The left and right ends of the front end of the hinge frame 8 are inserted and connected to the limit plug 10, and the limit plug 10 is set in a snap-fit ​​state with the positioning hole 12. The second screw 9 is threadedly connected to the outside of the hinge frame 8, and the rod of the second screw 9 is threadedly connected to the rotating sleeve 6. The first screw 7 is adjusted according to the mounting hole, and the limiting rod 10 is pulled out from the positioning hole 12, thereby releasing the fixation between the hinge frame 8 and the sliding rod 11. Then, the hinge frame 8 can be pushed to slide on the body of the sliding rod 11. The sliding of the hinge frame 8 drives the sliding block 5 to slide in the groove of the slide groove 4, thereby aligning the first screw 7 with the mounting hole. After the first screw 7 is aligned with the designated mounting hole, the limiting rod 10 is inserted to the left and right ends of the hinge frame 8 and engages with the positioning hole 12, thereby fixing the hinge frame 8 and the sliding rod 11 together, thus fixing the position of the first screw 7. By adjusting the position of the first screw 7, it can be aligned with the pre-installed hole position. The adjustment of the first screw 7 can cover a wider range of hole spacing, so that there is no need to re-drill holes or replace the static hinge 1 and the moving hinge 2, and ensure that the ideal gap and closing force are achieved when closed.

[0027] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5As shown, when the first screw 7 is aligned with the pre-installation hole, the second screw 9 fixes the hinge frame 8 and the rotating sleeve 6 together through the thread. The second screw 9 can then be turned to release the fixation between the hinge frame 8 and the rotating sleeve 6, allowing the first screw 7 to be pressed and fixed. Then the rotating sleeve 6 can be rotated and rotated inside the sliding block 5. The rotation of the rotating sleeve 6 can drive the first screw 7 to extend and retract, and the extension and retraction of the first screw 7 can connect it to the pre-installation hole. Alternatively, the second screw 9 can be turned directly without turning the first screw 7, connecting it to the pre-installation hole. The rotating sleeve 6 and the rotating first screw 7 can also be combined by rotating them, making the installation more secure. This allows the installation to be completed without complicated tools, which is not only convenient for installation but also facilitates subsequent disassembly or replacement of parts and reduces installation time.

[0028] As attached Figure 1 Appendix Figure 2 Appendix Figure 5 and attached Figure 6 As shown, when the stationary hinge 1 and the movable hinge 2 are used in cabinets or doors and windows, an oil reservoir 13 is fixedly installed on the top of the stationary hinge 1, and a push rod 14 is slidably connected to the left end of the oil reservoir 13. A piston 15 is fixedly installed on one end of the push rod 14 inside the oil reservoir 13, and an oil outlet pipe 16 is fixedly installed on the right end of the oil reservoir 13. A guide groove 17 is provided on the top of the stationary hinge 1, and the guide groove 17 is set in a corresponding state with the connection between the stationary hinge 1 and the movable hinge 2. The oil outlet pipe 16 is also set in a corresponding state with the guide groove 17. During daily use, lubricating oil can be injected into the oil reservoir 13 through the oil filling port on the oil reservoir 13. After the oil reservoir 13 is filled with lubricating oil, due to the diameter of the piston 15... The piston 15 is sized to match the diameter of the inner cavity of the oil reservoir 13, thus pushing the push rod 14. This causes the push rod 14 to move the piston 15 inside the oil reservoir 13. The movement of the piston 15 moves the lubricating oil inside the oil reservoir 13, pushing it to the right. The lubricating oil then flows through the oil outlet pipe 16 into the guide groove 17 and into the connection between the stationary hinge 1 and the moving hinge 2, thus lubricating the connection between the stationary hinge 1 and the moving hinge 2. Then, by pulling the push rod 14 again, the piston 15 moves to the left, keeping the lubricating oil level and stationary inside the oil reservoir 13. Pushing the piston 15 prevents the connection between the stationary hinge 1 and the moving hinge 2 from drying out, which could lead to damping instability or a decrease in self-closing force, thus maintaining a longer period of quiet operation.
