Description
Technical Field
[0001] This utility model relates to the field of hinge technology, and in particular to a folding self-locking structure and a lamp using the same. Background Technology
[0002] Currently, hinges are widely used in home, construction and industrial fields, such as room doors, cabinet doors, wardrobe doors, drawers, windows, curtain walls, car doors, hoods, machinery equipment doors or medical devices, etc.
[0003] A hinge is a mechanical device used to connect two objects (usually rigid components) and allow them to rotate relative to each other about a common axis. It is the core component for realizing the opening, closing, folding, or rotation functions of an object. Essentially, it connects two movable parts through an axis structure, ensuring both connection stability and flexible motion transmission. Common design flaws include jamming and abnormal noise, insufficient load-bearing capacity and deformation, excessive wear and component breakage, installation misalignment, and uneven stress.
[0004] Traditional 180° folding hinges have limited functionality, lack automatic locking when unfolded to a horizontal position, have insufficient rigidity support, and lack self-locking and deformation resistance. Currently, no effective solutions have been proposed to address these issues. Utility Model Content
[0005] Purpose of the utility model: To provide a folding self-locking structure and a lamp using the same, so as to at least solve one of the problems existing in the prior art.
[0006] Technical solution: A folding and unfolding self-locking structure, comprising:
[0007] First fastener;
[0008] A hinged component, one end of which is connected to the first fixing component;
[0009] A second fixing member is connected to the other end of the hinge member and can rotate to fold or unfold with the first fixing member;
[0010] Two locking fasteners are disposed opposite each other on the second fixing member near the hinge member along a predetermined direction; and
[0011] A locking element is installed inside the first fixing element;
[0012] When the first fixing member and the second fixing member rotate along the hinge to the fully extended state, the two locking members are respectively inserted into the locking member for self-locking, so that the first fixing member and the second fixing member form a rigid whole.
[0013] Preferably, a locking accessory is provided through one side of the first fixing member and connected to one end of the locking member, and an elastic member is provided at the other end of the first fixing member and connected to the other end of the locking member.
[0014] The lock accessory has a locked state and a released state. In the locked state, the lock accessory applies a locking force to one end of the locking member to ensure a tight fit between the locking member and the two locking fasteners. In the released state, after releasing the locking force to one end of the locking member, the lock accessory applies an additional compressive force to the lock accessory. The elastic element contracts under the compressive force, and the locking member slides away from the locking fasteners, causing the locking fasteners and the locking member to rotate and separate along the hinge to return to the folded state.
[0015] Preferably, both locking components have an arc-shaped inclined surface on the same side, the width of the inclined surface decreases from top to bottom, and a snap-fit hole is also provided on the locking component;
[0016] Each of the mortise lock components is provided with a wedge-shaped locking tongue that extends toward the lock attachment;
[0017] The latch gradually slides into the inclined surface, pushing the locking element to move towards the elastic element so that the locking element is continuously inserted into the locking element.
[0018] Preferably, the first fixing member is further provided with two limiting members for restricting the degree of freedom of the locking member, and the two limiting members are located on the outer edge of the locking member.
[0019] Preferably, the first fastener includes: a semi-open first U-shaped bend with stepped sides, a first enclosure plate is provided on the side of the first U-shaped bend plate near the hinge, a first through hole is provided at the center of the first enclosure plate, and two through slots for the locking member to enter and exit are symmetrically provided on both sides of the first through hole.
[0020] Preferably, the first U-shaped bend includes: a first side plate and a second side plate disposed opposite to each other, wherein the first side plate has a countersunk hole for the lock accessory to enter and exit, and the inner wall of the second side plate has a limiting groove for limiting the elastic element.
[0021] The countersunk hole and the limiting groove are arranged at the same center.
[0022] Preferably, the first side plate, the second side plate, the first enclosure plate, a top plate, and a step enclose a semi-open chamber for assembling a locking member, wherein the locking member is oriented and displaced within the semi-open chamber.
[0023] Preferably, the second fastener includes: a semi-open second U-shaped bend with stepped sides, a second enclosure plate is provided on the side of the second U-shaped bend plate near the hinge member, and a second through hole is provided at the center of the second enclosure plate.
[0024] Preferably, the two ends of the locking member are respectively provided with a threaded portion near the side of the lock accessory and an assembly hole near the side of the elastic member.
[0025] The threaded portion, the mounting hole, and the countersunk hole are arranged at the same center.
[0026] To achieve the above objectives, according to another aspect of this application, a lighting fixture is also provided.
[0027] The lighting fixture according to this application includes the aforementioned folding self-locking structure.
[0028] Beneficial effects: In this embodiment, a self-locking method is adopted. When the first fixing member and the second fixing member rotate along the hinge to the fully unfolded state, the two locking members are respectively inserted into the locking member for self-locking and limiting, so that the first fixing member and the second fixing member form a rigid whole, achieving the purpose of keeping the structure fixed when fully unfolded. This achieves the technical effect of increasing the structural function and improving the structural stability in the unfolded state, thereby solving the technical problems of traditional 180° folding hinges having a single function, no automatic limiting function when unfolded to a horizontal state, insufficient rigid support after unfolding, and lack of self-locking and anti-deformation ability.

Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.
[0057] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0058] like Figure 1-14 As shown, this application relates to a folding self-locking structure and a lighting fixture using the same. Figure 1 As shown, the folding self-locking structure A includes: a first fixing member 10; the first fixing member 10 refers to a main support base of the entire structure, which can achieve good fixing and assembly effects; at the same time, it can also provide a foundation and guarantee for the assembly of other components. Of course, the first fixing member 10 can be a fixing plate.
[0059] Preferably, the first fixing member 10 has a mounting groove on the side near the hinge member 20. This allows for good assembly with the hinge member 20, while also achieving a concealed assembly effect.
[0060] A hinge 20 is connected at one end to the first fixing member 10; one end of the hinge 20 is connected to the first fixing member 10, and the other end is connected to the second fixing member 30; it enables folding or unfolding rotational movements between the first fixing member 10 and the second fixing member 30. The hinge 20 can be a hinge or a pivot.
[0061] A second fixing member 30 is connected to the other end of the hinge member 20 and rotates to fold or unfold with the first fixing member 10; the second fixing member 30 is another basic part of the structure, associated with the first fixing member 10 through the hinge member 20, and can rotate relative to the first fixing member 10 about the hinge point.
[0062] It should be noted that when fully folded, the second fastener 30 is in contact with (or close to) the first fastener 10; when fully unfolded, the second fastener 30 and the first fastener 10 are aligned at 180 degrees.
[0063] Preferably, the second fixing member 30 has a mounting groove on the side near the hinge member 20. This allows for good assembly with the hinge member 20, while also achieving a concealed assembly effect.
[0064] Furthermore, the first fixing member 10 and the second fixing member 30 are respectively connected to the hinge member 20 via the connecting member 90. The connecting member 90 can be a KM4*14 machine screw.
[0065] Furthermore, the first fixing member 10 and the second fixing member 30 are each provided with a plurality of mounting holes. This enables good assembly with other components and also facilitates easy assembly and disassembly.
[0066] Two locking fasteners 40 are disposed opposite to each other on the second fixing member 30 near the hinge member 20 along a preset direction. The two locking fasteners 40 are fixed to the second fixing member 30 near the hinge member 20, and the two locking fasteners 40 are disposed opposite to each other along the preset direction. This enables them to cooperate with the locking member 50 on the first fixing member 10 to achieve the effect of limiting and self-locking, thereby ensuring the stability of the structure. The preset direction can be a vertical direction or the Z-axis direction in a three-coordinate system.
[0067] A locking element 50 is disposed within the first fixing member 10; the locking element 50 is vertically disposed inside the first fixing member 10 and is used to receive and lock the two locking fasteners 40 on the second fixing member 30. When the first fixing member 10 and the second fixing member 30 are fully extended, the locking fasteners 40 are inserted into the slots of the locking element 50, completing the self-locking limit.
[0068] Preferably, the locking element 50 can be a pin. This allows for easy implementation and convenient operation.
[0069] Preferably, an elastic element 70 is provided at the end of the locking member 50 away from the locking attachment 60; this can further improve the self-locking effect of the locking member 50.
[0070] When the first fixing member 10 and the second fixing member 30 rotate along the hinge member 20 to the fully extended state, the two locking members 40 are respectively inserted into the locking member 50 for self-locking, so that the first fixing member 10 and the second fixing member 30 form a rigid whole.
[0071] Specifically, in the folded state: the second fixing member 30 rotates around the hinge member 20 towards the first fixing member 10 to fold up, or the first fixing member 10 and the second fixing member 30 move away from the hinge member 20 simultaneously, and the locking member 40 separates from the latching member 50. This structure is in the loosened state and can be moved or stored freely.
[0072] Deployed state: The second fixing member 30 rotates around the hinge member 20 until it is in a straight line with the first fixing member 10.
[0073] During the rotation, the two locking pieces 40 on the second fixing member 30 are continuously inserted into the locking pieces 50 inside the first fixing member 10; until they are in place (fully unfolded), the two locking pieces 40 on the second fixing member 30 are simultaneously fully inserted into the locking pieces 50 inside the first fixing member 10.
[0074] After the locking element 40 enters the locking element 50, the shape of the locking element 40 and the slot match, creating a limiting and self-locking effect, fixing the two parts into a rigid whole. Furthermore, the elastic element 70 located at one end of the locking element 50 provides a rebound force to further improve the locking effect.
[0075] As can be seen from the above description, this application achieves the following technical effects:
[0076] In this embodiment, a self-locking mechanism is adopted. When the first fixing member 10 and the second fixing member 30 rotate along the hinge member 20 to the fully unfolded state, the two locking members 40 are respectively inserted into the locking member 50 for self-locking and limiting, so that the first fixing member 10 and the second fixing member 30 form a rigid whole, achieving the purpose of keeping the structure fixed when fully unfolded. This achieves the technical effect of increasing the structural function and improving the structural stability in the unfolded state, thereby solving the technical problems of traditional 180° folding hinges having a single function, lacking automatic limiting function when unfolded to a horizontal state, insufficient rigid support after unfolding, and lacking self-locking and anti-deformation capabilities.
[0077] Furthermore, a locking accessory 60 is provided through one side of the first fixing member 10 and connected to one end of the locking member 50, and an elastic member 70 is provided at the other end of the first fixing member 10 and connected to the other end of the locking member 50.
[0078] The locking accessory 60 has a locked state and a released state. In the locked state, the locking accessory 60 applies a locking force to one end of the locking member 50 to ensure a tight fit between the locking member 50 and the two locking fasteners 40. In the released state, after releasing the locking force to one end of the locking member 50, the locking accessory 60 applies additional compressive force to the locking accessory 60. The elastic member 70 contracts under the compressive force, and the locking member 50 slides away from the locking fasteners 40. Rotation at this point causes the locking fasteners 40 and the locking member 50 to rotate and separate along the hinge 20, returning to a folded state. It is understood that the locking accessory 60 is installed on one side of the first fixing member 10 and connected to one end of the locking member 50. It has two states: 1. Locked state: Applying a locking force to the locking member 50 to make the locking member 50 and the locking fasteners 40 more tightly engaged. Second, in the released state, no locking force is applied, and it can also act as a push pin. When an external force is applied, the locking part 50 moves towards the elastic part (70) to release the locking part 40, which facilitates the separation of the first fixing part 10 and the second fixing part 30.
[0079] The elastic element 70 is mounted on the other end of the first fixing element 10 and connected to the other end of the locking element 50. It is able to provide a restoring force when the applied external force is removed, pushing the locking element 50 back into place.
[0080] Preferably, the locking accessory 60 can be a PM3*12 machine screw.
[0081] Preferably, the elastic element 70 can be a spring.
[0082] Furthermore, each of the two locking members 40 has an arc-shaped inclined surface 401 on the same side, the width of the inclined surface 401 decreasing from top to bottom, and a snap-fit hole 402 is also provided on the locking member 40.
[0083] Each of the locking components 50 is provided with a locking tongue 501 that extends toward the lock attachment 60 and is wedge-shaped;
[0084] The latch 501 gradually slides into the inclined surface 401, pushing the locking member 40 towards the elastic member 70 so that the locking member 40 is continuously inserted into the locking member 50. It can be understood that the locking member 40 has an inclined surface 401 (with curvature, and the width decreases from top to bottom) on the side that contacts the locking member 50.
[0085] The inner side of the mortise lock 50 has a wedge-shaped latch 501, which points towards the side of the lock accessory 60.
[0086] Specifically, when unfolded, the inclined surface 401 contacts the locking tongue 501 and slides gradually, pushing the locking member 50 to move towards the elastic member 70. The locking member 40 continues to penetrate deeper into the locking member 50, achieving smooth and reliable self-locking.
[0087] To achieve automatic guidance, a wedge-shaped fit is adopted between the inclined surface 401 and the locking tongue 501, which can guide the locking fastener 40 to automatically enter the slot without precise alignment.
[0088] Reduced jamming: The progressive sliding fit reduces insertion resistance and extends the life of the parts.
[0089] Tighter locking: The wedge-shaped latch 501 generates lateral pressure when fully inserted, making the latch 40 and the bolt 50 fit more firmly.
[0090] Furthermore, the first fixing member 10 is also provided with two limiting members 80 for restricting the degrees of freedom of the locking member 50. The two limiting members 80 are located at the outer edge of the locking member 50. It can be understood that by restricting the degrees of freedom of the locking member 50 in the non-working direction, it is only allowed to move along the designed direction (the direction of the locking attachment 60 and the elastic member 70). This can prevent shaking and prevent the locking member 50 from loosening due to vibration after locking; it can also accurately position the locking member 50 to ensure that it is aligned with the locking member 40 each time it is unfolded; at the same time, it extends the service life and reduces frictional damage caused by misalignment.
[0091] Preferably, the limiting component 80 can be a pin.
[0092] like Figure 10 As shown, the first fastener 10 includes: a semi-open first U-shaped bend 101 with stepped sides; a first surrounding plate 102 is provided on the side of the first U-shaped bend 101 near the hinge member 20; a first through hole 103 is provided at the center of the first surrounding plate 102; and two through slots 104 are symmetrically provided on both sides of the first through hole 103 for the locking member 40 to enter and exit. It can be understood that this design facilitates assembly and also reduces the weight of the first fastener 10.
[0093] like Figure 11 As shown, the first U-shaped bending portion 101 includes: a first side plate 1011 and a second side plate 1012 disposed opposite to each other. The first side plate 1011 is provided with a countersunk hole 1013 for the lock accessory 60 to enter and exit. The inner wall of the second side plate 1012 is provided with a limiting groove 1014 for limiting the elastic member 70.
[0094] The countersunk hole 1013 and the limiting groove 1014 are co-centered. This design achieves good assembly while concealing the internal locking structure to prevent dust ingress, thus improving service life and aesthetics.
[0095] Furthermore, the first side plate 1011, the second side plate 1012, the first surrounding plate 102, a top plate 1015, and a step 1016 enclose a semi-open chamber for assembling the locking member 50, wherein the locking member 50 is located within the semi-open chamber and undergoes directional displacement. It is understood that the semi-open chamber structure facilitates the direct embedding of components such as the locking member 50 and the elastic element 70, thereby achieving the effect of easy assembly; simultaneously, it also allows for the directional movement of the locking member 50.
[0096] like Figure 6 As shown, the second fastener 30 includes: a semi-open second U-shaped bend 301 with stepped sides; a second surrounding plate 302 is provided on the side of the second U-shaped bend 301 near the hinge member 20; and a second through hole 303 is provided at the center of the second surrounding plate 302. It is understood that this design facilitates assembly and reduces the weight of the second fastener 30.
[0097] like Figure 9 As shown, the two ends of the locking member 50 and located at the center are respectively provided with a threaded portion 502 near the side of the lock accessory 60 and an assembly hole 503 near the side of the elastic member 70.
[0098] The threaded portion 502, the mounting hole 503, and the countersunk hole 1013 are arranged concentrically. This ensures that the locking element 50, the locking accessory 60, and the elastic element 70 are installed coaxially, reducing eccentric wear. The mounting hole 503 and the limiting groove 1014 enable a good assembly effect for the elastic element 70.
[0099] Specifically, when in the unfolded state, the second fixing member 30 rotates around the hinge member 20 and aligns with the first fixing member 10. The inclined surface 401 contacts the locking tongue 501, gradually pushing the locking member 40 into the locking member 50 to complete the self-locking. The locking accessory 60 is tightened to be in the locked state to further prevent loosening.
[0100] When in the folded state, release the lock attachment 60 to switch to the released state; apply external force, such as pressing the lock attachment 60, to push the latch 50 toward the elastic member 70, so that it separates from the latch member 40; the second fixing member 30 can be freely folded and retracted.
[0101] The installation process of the self-locking folding structure A in this application is as follows:
[0102] I. For example Figure 2 As shown, align the mounting holes of the hinge 20 and the first fixing member 10, and tighten them with KM4*14 machine screws;
[0103] 2. Lock the hinge 20 onto the second fastener 30 using the same method;
[0104] III. Figure 3 As shown, the elastic element 70 is inserted into the circular groove of the locking element 50, and then the locking element 50 and the elastic element 70 are installed together into the square groove of the first fixing element 10.
[0105] Fourth, the locking accessory 60 passes through the through hole of the first fixing member 10 and locks into the threaded hole of the locking member 50, and finally the limiting member 80 is installed.
[0106] The specific working principle of this application is as follows:
[0107] I. For example Figure 2 As shown, the structure is initially in a folded state; with the first fixing member 10 stationary, rotating the second fixing member 30 causes the folded structure to unfold, as shown. Figure 4 As shown;
[0108] II. Figure 5 As shown, when the folding structure is unfolded to a certain angle, the lower side of the latch 40 on the second fixing member 30 will first contact the inclined surface of the latch 501. The latch 40 on the second fixing member 30, as shown... Figure 6 As shown, it is wider at the top and narrower at the bottom, and the sloping surface has a certain curvature; the locking tongue 501 on the locking piece 50, as... Figure 7 As shown, it is wedge-shaped; at this time, the folding structure continues to unfold, and the lower side of the latch 40 on the second fixing member 30 will press the tip of the latch tongue 501, causing the locking member 50 to move towards the elastic member 70. At this time, the elastic member 70 will be continuously squeezed and deformed as the folding structure unfolds.
[0109] Third, when the folding structure is unfolded to the horizontal state, the latch hole 402 of the second fixing member 30 moves to be aligned with the latch 502. Since the latch 502 is no longer squeezed by the latching member 40 on the second fixing member 30, the latching member 50 will be inserted into the latch hole 402 of the second fixing member 30 under the spring force of the elastic member 70, thus realizing the self-locking function.
[0110] IV. Figure 12As shown, when the folding structure is unfolded to a horizontal state, the latch 40 on the second fixing member 30 becomes the force point for the horizontal rigid support, working together with the hinge member 20 to make the first fixing member 10 and the second fixing member 30 form a rigid whole. At this time, the locking accessory 60 is tightened with a Phillips screwdriver, causing the locking tongue 501 on the locking member 50 to move in the insertion direction, structurally strengthening the locking force of the locking member 50 and making the overall structure more tightly integrated;
[0111] V. For example Figure 13 As shown, from the horizontal unfolding to the folding (restoration) process, use a Phillips screwdriver to unscrew the lock accessory 60 by about 5mm. At this time, press the lock accessory 60 with your hand to move the pin inward (in the direction of spring compression), so that the latch 501 on the lock piece 50 exits the latch hole 402 of the second fixing member 30. Then, let the second fixing member 30 move clockwise to a certain angle and then release the lock accessory 60. The lock piece 50 will return to the initial installation position under the spring deformation force of the elastic member 70. At this time, the unlocking process of the folding structure is completed.
[0112] like Figure 14 As shown, this application also relates to a lighting fixture, including the aforementioned folding self-locking structure A.
[0113] Specifically, this application can also be applied to linear lighting fixtures. Because conventional linear lighting fixtures are relatively long, they cause problems such as difficult packaging, difficult transportation, and high costs. Therefore, installing folding structure modules on lighting fixtures can shorten the packaging size and facilitate transportation, thereby reducing packaging and transportation costs.
[0114] This application also has the following beneficial effects:
[0115] First, it is easy to install. The first fixing member 10 and the second fixing member 30 have mounting holes, which makes it easy to install on other structures.
[0116] Second, it can achieve rapid self-locking by rotation and closing, without the need for other structural assistance;
[0117] Third, it has a reinforced locking structure, making the overall structure more robust;
[0118] IV. It can be quickly restored without disassembling other structural parts;
[0119] 5. Automatic self-locking: When the first fixing member 10 and the second fixing member 30 are unfolded into place, the locking member 40 naturally inserts into the locking member 50; this improves the convenience and speed of unfolding and fixing.
[0120] VI. The structure is stable, with a double-point locking system of "two locking fasteners 40 + mortise locking fasteners 50" to form a stable mechanical support structure and prevent loosening; and the overall rigidity is increased after unfolding, resulting in a higher load-bearing capacity.
[0121] 7. Prevents accidental folding: The self-locking structure effectively prevents accidental folding due to vibration, collision, or other reasons during use, ensuring safety.
[0122] 8. Easy to assemble and disassemble. When folding is required, simply remove the locking buckle 40 from the locking piece 50 to achieve quick folding.
[0123] 9. Long service life, adopts mechanical self-locking, no need for additional power or complex parts, strong wear resistance, and adaptable to multiple opening and closing operations;
