Abstract
Description
Technical Field
[0001] This utility model relates to the field of hardware accessories technology, and in particular to a torque-regulating hinge. Background Technology
[0002] Currently available screen doors are either sliding doors or hinged doors; hinged doors typically rely on hinges to rotate and open. Quality defects such as dimensional deviations or incomplete closing can occur due to installation methods, assembly errors, or even the precision of the product itself.
[0003] 1. Traditional screen doors often fail to prevent mosquitoes from entering due to gaps caused by improper closing when the door is installed. A magnetic device or a hook is needed to close the door a second time.
[0004] Second, some screen doors may have torsion springs added to the hinges, but the closing force is already set at the factory. If the closing force is too large after installation, the user cannot adjust it himself, and some may have quality problems such as abnormal noise. Utility Model Content

[0006] This utility model is implemented using the following method: a torque-adjustable storage hinge, comprising an upper hinge body and a lower hinge body, the upper hinge body and the lower hinge body being rotatably connected, and an adjustment guide cavity being provided between the upper hinge body and the lower hinge body; it also includes a torque adjustment component, the torque adjustment component comprising a torsion spring and a torque adjustment seat installed in the adjustment guide cavity, one end of the torsion spring being connected to one end of the adjustment guide cavity, the other end of the torsion spring being connected to the torque adjustment seat, and an adjustment seat drive component being provided on the side wall of the adjustment guide cavity at a position opposite to the torque adjustment seat, for driving the torque adjustment seat to move in the adjustment guide cavity.
[0007] Preferably, the contact surface between the torque adjusting seat and the adjusting seat drive is an inclined surface or a curved surface, and the depth of the adjusting seat drive into the adjusting guide cavity changes the contact position on the contact surface of the torque adjusting seat.
[0008] Preferably, the inner wall of the adjusting guide cavity is provided with a slide groove or slide rail, and the side wall of the torque adjusting seat that avoids the contact surface is provided with a corresponding slide rail or slide groove, and the slide rail cooperates with the slide groove.
[0009] Preferably, the adjusting guide cavity includes a first cylindrical chamber formed in the upper body of the hinge and a second cylindrical chamber formed in the lower body of the hinge. The first chamber and the second chamber are connected to each other. One end of the torsion spring is connected to the inner end face of the first chamber or to the inner end of the second chamber, and the other end of the torsion spring is connected to the torque adjusting seat. The driving position of the adjusting seat is located at a position that avoids the overlapping part of the upper body and the lower body of the hinge.
[0010] Preferably, the first chamber of the upper body of the hinge is fitted onto the outer wall of the second chamber of the lower body of the hinge, one end of the torsion spring is connected to the inner end of the first chamber, the torque adjustment seat is slidably disposed in the second chamber, and the slide groove or slide rail is disposed on the inner wall of the second chamber; the adjustment seat drive is disposed on the side wall of the lower body of the hinge.

[0015] Preferably, the contact surface is curved and gradually concave inward from the outer periphery of the contact surface.
[0016] The beneficial effects of this utility model are as follows: This utility model provides a torque-adjustable hinge, which, compared with the prior art, has at least the following technical effects: 1. An adjustment guide cavity is provided between the upper and lower parts of the hinge, and a torsion spring and a torque adjustment seat are installed in it. An adjustment seat drive is inserted through the side wall of the adjustment guide cavity. The insertion amount of the adjustment seat drive into the adjustment guide cavity drives the torque adjustment seat to move, thereby pulling the torsion spring to adjust the torque, making it convenient for users to adjust the closing force themselves. 2. The contact surface between the torque adjustment seat and the adjustment seat drive is an inclined surface. When the adjustment seat drive is continuously inserted, it can squeeze the torque adjustment seat to move it in the adjustment guide cavity, thereby stretching the torsion spring. When the adjustment seat drive is gradually withdrawn, the torsion spring is reset by its own force, thus realizing the self-adjustment of the closing force. 3. Slide rails or grooves are provided on the side walls of the adjustment guide cavity and the torque adjustment seat, respectively, which play a role in restricting the rotation of the torque adjustment seat, ensuring the continuity of the closing force, and keeping the adjustment seat drive in contact with the contact surface. 4. The first chamber is located on the upper part of the hinge, and the second chamber is located on the lower part of the hinge. Both are cylindrical, facilitating the assembly of the torque adjustment seat and torsion spring with the upper and lower parts of the hinge. Assembly is simple and convenient, and users can assemble them themselves. 5. A slide groove or rail is located on the inner wall of the second chamber, where the torque adjustment seat is installed. This prevents rotation, allowing the torsion spring to provide the closing force. 6. The adjustment seat drive is a bolt inserted into a threaded hole. Rotating the bolt changes the depth of the bolt within the second chamber, thus moving the torque adjustment seat. The adjustment method is simple and convenient, with a low learning curve, allowing users to quickly learn and adjust it themselves. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0026] Please see Figures 1 to 6 A torque-adjustable storage hinge includes an upper hinge body 1 and a lower hinge body 2, which are rotatably connected. An adjustment guide cavity is provided between the upper hinge body 1 and the lower hinge body 2. It also includes a torque adjustment component, which includes a torsion spring 3 and a torque adjustment seat 4 installed in the adjustment guide cavity. One end of the torsion spring 3 is connected to one end of the adjustment guide cavity, and the other end of the torsion spring 3 is connected to the torque adjustment seat 4. An adjustment seat drive component 5 is provided on the side wall of the adjustment guide cavity at a position opposite to the torque adjustment seat 4, for driving the torque adjustment seat 4 to move within the adjustment guide cavity. An adjustment guide cavity is provided between the upper hinge body 1 and the lower hinge body 2, and a torsion spring 3 and a torque adjustment seat 4 are installed in the cavity. An adjustment seat drive 5 is inserted through the side wall of the adjustment guide cavity. The torque adjustment seat 4 is moved by the extension of the adjustment seat drive 5 into the adjustment guide cavity, which in turn pulls the torsion spring 3 to adjust the torque, making it convenient for users to adjust the closing force themselves.
[0027] Please see Figures 1 to 4 Preferably, the contact surface 41 between the torque adjusting seat 4 and the adjusting seat drive 5 is an inclined surface or a curved surface, and the depth of the adjusting seat drive 5 entering the adjusting guide cavity changes the contact position on the contact surface 41 of the torque adjusting seat 4. Since the contact surface 41 between the torque adjusting seat 4 and the adjusting seat drive 5 is inclined, as the adjusting seat drive 5 is continuously inserted, it can compress the torque adjusting seat 4 to move it within the adjusting guide cavity, thereby stretching the torsion spring 3. As the adjusting seat drive 5 gradually withdraws in the opposite direction, the torsion spring 3 is reset by its own force, thus achieving self-adjustment of the tightening force.
[0028] Please see Figures 1 to 4Preferably, the inner wall of the adjusting guide cavity is provided with a sliding groove 42 or a sliding rail 21, and the side wall of the torque adjusting seat 4, which avoids the contact surface 41, is provided with a corresponding sliding rail 21 or sliding groove 42, and the sliding rail 21 cooperates with the sliding groove 42. The sliding rail 21 or sliding groove 42 provided on the side wall of the adjusting guide cavity and the torque adjusting seat 4 respectively serve to limit the rotation of the torque adjusting seat 4, ensure the continuity of the closing force, and keep the adjusting seat driving member 5 in contact with the contact surface 41.
[0029] Please see Figures 1 to 6 Preferably, the adjusting guide cavity includes a first cylindrical chamber 11 formed in the upper hinge body 1 and a second cylindrical chamber 22 formed in the lower hinge body 2. The first chamber 11 and the second chamber 22 are connected to each other. One end of the torsion spring is connected to the inner end face of the first chamber 11 or the inner end of the second chamber 22, and the other end of the torsion spring is connected to the torque adjusting seat 4. The adjusting seat driving member 5 is positioned to avoid the overlapping part of the upper hinge body 1 and the lower hinge body 2. The first chamber 11 is located in the upper hinge body 1, and the second chamber is located in the lower hinge body 2. Both are cylindrical, which facilitates the assembly of the torque adjusting seat 4 and the torsion spring 3 with the upper hinge body 1 and the lower hinge body 2. The assembly is simple and convenient, and the user can assemble it himself.
[0030] Please see Figures 1 to 6 Preferably, the first chamber 11 of the upper hinge body 1 is fitted onto the outer wall of the second chamber 22 of the lower hinge body 2. One end of the torsion spring is connected to the inner end of the first chamber 11. The torque adjusting seat 4 is slidably disposed in the second chamber 22. The slide groove 42 or slide rail 21 is disposed on the inner wall of the second chamber 22. The adjusting seat drive 5 is disposed on the side wall of the lower hinge body 2. The slide groove 42 or slide rail 21 is disposed on the inner wall of the second chamber 22, and the torque adjusting seat 4 is installed in the second chamber 22. This can play a role in preventing rotation, so that the torsion spring 3 can play a role in providing the closing force.
[0031] Please see Figures 1 to 6 Preferably, the adjusting seat drive component 5 is an adjusting bolt; the side wall of the hinge lower body 2 is provided with a threaded hole 23 that is perpendicular to and connected to the axis of the second chamber 22, and the adjusting bolt is disposed in the threaded hole 23. The adjusting seat drive component 5 is a bolt inserted into the threaded hole 23, so that the size of its intrusion into the second chamber 22 can be changed by rotating the bolt, that is, the driving torque adjusting seat 4 can be moved. The adjustment method is simple and convenient, with low learning cost, and allows users to quickly get started and adjust it themselves.
[0032] Please see Figures 1 to 2 , Figure 4Preferably, the end of the torque adjusting seat 4 connected to the torsion spring 3 is provided with a blocking part, and the distance between the inclined surface of the torque adjusting seat 4 and the threaded hole 23 gradually increases from the end away from the torsion spring 3 to the position close to the blocking part. The blocking part is provided with a hook groove to hook the torsion spring 3. This allows the adjusting bolt to be screwed into the torque adjusting seat 4 to stretch the torsion spring 3, and when it is screwed out, the torsion spring 3 drives it to return to its original position.
[0033] Please see Figure 2 Preferably, the inner circumferential surface of the first chamber 11 is provided with a limiting part 12, and the outer end surface of the second chamber 22 abuts against the limiting part 12. This facilitates the positioning and assembly of the upper hinge body 1 and the lower hinge body 2.
[0034] Please see Figures 1 to 6 Preferably, a connecting screw 6 is inserted through the side wall of the hinge body 1 near the inner end of the first chamber 11. The inner end face of the first chamber 11 has a mating surface that matches the curvature of the connecting screw 6. One end of the torsion spring 3 hooks between the connecting screw 6 and the mating surface. This serves to restrict the rotation of the end of the torsion spring 3, so that the torsion spring 3 can generate a closing force, and also facilitates the positioning and connection of the torsion spring 3 and the hinge body 1.
[0035] Please see Figure 4 The contact surface 41 is curved and gradually concave inward from its outer periphery. This ensures that the adjusting seat drive 5 remains in contact with the contact surface 41, and provides a limiting and guiding function for the movement of the adjusting seat drive 5 relative to the torque adjusting seat 4.
[0036] The working principle of this utility model is as follows:
[0037] The lower hinge body 2 and the upper hinge body 1 are connected by a torsion spring 3 and a torque adjustment seat 4 to form a rotatable body. One end of the torsion spring 3 is directly fixed by the connecting screw 6 of the upper hinge body 1, and the other end is connected to the torque adjustment seat 4. The side end of the lower hinge body 2 has a threaded hole 23, which matches an adjusting bolt. The adjusting bolt presses against the torque adjustment seat 4 (e.g., ...). Figures 1 to 4 As shown); the torque of the torsion spring 3 can be adjusted by tightening the bolts, thus controlling the torque of the hinge. The internal design of the hinge allows for adjusting the twisting torque of the bolts to increase the stroke of the torsion spring 3, thereby increasing the torque (e.g., Figure 1 , Figure 2 (As shown).
[0038] By rotating the adjusting bolt, the torque adjusting seat 4 is moved along the second chamber 22 to tighten the torsion spring 3 to the desired tightness. When opening and closing, the fit between the screen door 7 and the door frame is adjusted (see details). Figure 5 , Figure 6 Furthermore, it effectively addresses the technical shortcomings of the existing screen door 7 in its fit with the door frame.
[0039] When it is necessary to remove the screen door 7, the adjusting bolt is completely unscrewed from the threaded hole 23, and the torque adjusting seat 4 can be dislodged from the second chamber 22, and the upper hinge body 1 and the lower hinge body 2 can be separated.
