Description

Technical Field

[0001] This utility model relates to the field of locking structures and lighting fixtures. Background Technology

[0002] Locking structures typically enable two components to be locked together, preventing relative movement between them (hereinafter referred to as the first and second components for ease of description) under accidental impact from external forces. Therefore, locking structures are widely used in various technical fields. When applied to existing lighting fixtures, they are usually installed between the fixture body and the base to achieve locking or unlocking between the fixture body and the base.

[0003] Currently, the locking structure designs in lighting products are quite diverse, but a common structure involves locking the lamp body and base by squeezing and clamping at their joint surfaces. However, this tight fit during locking and unlocking can easily cause wear on the joint surfaces, and after long-term use, the tight fit can loosen. Under accidental impact, the first and second components (in the case of a lamp, the lamp body and base) can easily unlock, potentially damaging the product (lamp). Therefore, further improvements to the locking structure and the lamp itself are needed. Utility Model Content

[0004] The first technical problem to be solved by this utility model is to provide a locking structure that can reliably lock, in light of the above-mentioned existing technology.

[0005] The second technical problem to be solved by this utility model is to provide a lamp with the above-mentioned locking structure, which provides a good locking effect between the lamp body and the base, and will not unlock even under external impact.

[0006] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: The locking structure includes a joint portion that is mutually squeezed and tightly fitted between a first component and a second component. The structure is characterized by further including a push button that is slidably constrained on the first component and a first hook portion that slides together with the push button. The second component is provided with a second hook portion corresponding to the first hook portion. When the first hook portion slides with the push button until it is engaged with the second hook portion, it can prevent the joint portion that is mutually squeezed and tightly fitted from disengaging. When the first hook portion continues to slide with the push button and the second hook portion is disengaged, the joint portion that is mutually squeezed and tightly fitted can be unlocked.

[0007] To improve stability, preferably, the first hook and the corresponding second hook form a pair of hooking groups, with at least two hooking groups respectively disposed on both sides of the aforementioned mutually pressing and clamping joint. The distribution of the hooking groups on both sides of the joint allows for a more balanced force distribution between the first and second components, thereby further improving the stability of their locking.

[0008] For ease of manufacturing, preferably, the joint on the first component is configured as a first protrusion, and the joint on the second component is designed as a second protrusion whose bottom surface fits tightly with the top surface of the first protrusion. The bottom surface of the second protrusion has grooves on both sides to form the second hook. This design makes the overall structure more compact.

[0009] In a further improvement, the second component includes a base and a locking plate connected to the base and accommodating the push button. The engaging portion and the second hook portion of the second component are both located on the locking plate. The base and the locking plate can be integrally formed, simplifying the assembly process. The locking plate integrates the engaging portion and the second hook portion, which can cooperate with the engaging portion and the first hook portion of the push button on the first component to achieve locking.

[0010] Of course, the aforementioned locking plate and base can also be designed such that the locking plate is hinged to the base via a pin, and a torsion spring is mounted on the pin to ensure that the joint between the first component and the second component always has a tendency to press and fit together. By hinged to the base, the locking plate can move in a direction away from or towards the push button, while the torsion spring allows for rapid resetting of the locking plate towards the push button, thus ensuring that the joint between the first component and the second component always maintains a tight fit.

[0011] For ease of unlocking, preferably, the push button has a first inclined surface facing the lock plate, and the locking plate's mating end has a second inclined surface corresponding to the first inclined surface. When the first hook and the second hook are engaged, the first and second inclined surfaces contact each other. As the push button continues to slide towards the lock plate, the first inclined surface pushes the mating end of the lock plate away from the push button (offsets). During unlocking, the second hook on the lock plate needs to be separated from the first hook on the push button beforehand. The cooperation of the first and second inclined surfaces allows the push button to apply a force that offsets the lock plate away from the push button as it continues to slide, thus facilitating the unlocking of both the first and second hooks.

[0012] For ease of operation, preferably, the angle α between the first inclined plane and the vertical direction is 30° to 45°. When the angle of the first inclined plane is less than 30°, the sliding stroke of the push button is longer, affecting the unlocking efficiency; when the angle of the first inclined plane is greater than 45°, the user will have to exert more effort when pressing.

[0013] A further improvement is that the first inclined surface is provided with a rod extending toward the locking plate side, and the first hook is located on the rod. After the rod extends, it will deform slightly when subjected to force, so that the first hook can smoothly engage with the second hook during the sliding process.

[0014] To ensure reliability after engagement, preferably, an elastic element is also included, mounted on the first component and acting on the push button. This elastic element ensures that the push button always tends to move away from the second hook. Thus, when the second hook and the first hook are engaged, the elastic element provides a force to the first hook in the opposite direction to the aforementioned sliding direction, ensuring that the first and second hooks remain tightly engaged, thereby enhancing the reliability of the engagement.

[0015] To facilitate locking, the first hook has a third inclined surface facing the second hook, and the second hook has a fourth inclined surface that engages with the third inclined surface. When the joint between the first and second components begins to press and tighten, the fourth inclined surface presses against the third inclined surface, compressing the elastic element and causing the first hook to slide and engage with the second hook. Thus, during locking, there is no need to push the button; the first and second hooks automatically engage after locking, effectively opening a safety switch and ensuring a reliable locked state that prevents arbitrarily opening.

[0016] For ease of installation, preferably, the first component has a recessed area, in which the push button and the connecting portion on the first component are both located. Specifically, the first component has a partially recessed area that provides a space for mounting the push button and the connecting portion on the first component, while also improving the compactness of the lamp structure.

[0017] To avoid interference, preferably, the push button is provided with a clearance groove for the joint on the first component to pass through. By providing the clearance groove, interference between the push button and the joint on the first component can be prevented when the push button slides.

[0018] The technical solution adopted by this utility model to solve the second technical problem mentioned above is as follows: a lamp includes a handle that can accommodate a battery and a base hinged to the bottom of the handle, and a locking structure is provided between the handle and the base. The locking structure is characterized in that: the locking structure adopts the above-mentioned locking structure, one of the handle and the base is a first component, and the other of the handle and the base is a second component.

[0019] Compared with existing technologies, the advantages of this invention are as follows: By providing a mutually pressing and tightly fitted joint between the first and second components, locking can be achieved. Simultaneously, the engagement of the first hook on the push button and the second hook on the second component acts as an additional safety switch. When they can hook together, the disengagement of the aforementioned tightly fitted joint is prevented. Therefore, even under external impact, the first and second components will not easily unlock, thus improving the reliability and safety in the locked state. Furthermore, a single "push" action allows the push button to slide in the same direction, first disengaging the first and second hooks to release the safety, and then releasing the clamping force, thereby conveniently achieving the purpose of opening the safety and releasing the locking force. The above effects are even more pronounced when this locking structure is applied to lighting fixtures. Attached Figure Description

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Example 1:

[0033] The locking structure in this embodiment connects the first component 1 and the second component 2, enabling the locking or unlocking of both components. Therefore, it can be widely applied to products requiring locking or unlocking, such as between a case and its lid, or between a box and its lid. To fully understand this structure, this embodiment applies the locking structure to a lighting fixture. Lighting fixtures have diverse structures; [The following is an example...] Figures 1 to 8 The work lamp shown is used as an example to illustrate the preferred embodiment of this utility model. The locking structure includes a mutually pressing and tight-fitting joint between the first component 1 and the second component 2 (specifically, the first protrusion 11 on the first component 1 and the second protrusion 23 provided on the locking plate 22). Referring to the specific product in the figure, the first component 1 is the handle 7 that can accommodate the battery, and the second component 2 is the base 8 that is hinged to the bottom of the handle 7. The locking structure is provided between the handle 7 and the base 8. In order not to cause confusion, the handle 7 and the base 8 will still be referred to as the first component 1 and the second component 2 in the following description of the locking structure.

[0034] The aforementioned push button 3 is slidably constrained to the first component 1. The structure of the sliding constraint can adopt existing technology, see reference. Figure 5 The first component 1 has a recessed area 12, which forms an accommodating space for the installation of a push button 3. The two sides of the push button 3 cooperate with the corresponding sliding grooves 121 provided on the recessed area 12, allowing the push button 3 to slide up and down on the first component 1. The push button 3 has a first hook 31 that can slide together with the push button 3 (or indirectly linked). The second component 2 has a second hook 231 corresponding to the first hook 31. When the first hook 31 slides down with the push button 3 until it is engaged with the second hook 231, it can prevent the disengagement of the mutually pressing and tightly fitted joint. When the first hook 31 continues to slide down with the push button 3 until it is disengaged from the second hook 231, the mutually pressing and tightly fitted joint can be unlocked.

[0035] For details, please refer to Figures 2 to 4 The first hook portion 31 and the corresponding second hook portion 231 form a pair of hooking groups. In order to improve reliability and facilitate processing, the preferred hooking groups in this embodiment are two groups (of course, more than two groups can be designed as needed), and they are symmetrically distributed on both sides of the joint where they are pressed and fitted together. This makes the force between the first component 1 and the second component 2 more balanced, thereby improving the stability and reliability of the locking between the two.

[0036] The up-and-down sliding of the aforementioned push button 3 can be damped between it and the first component 1, allowing it to slide to the desired position under external force. However, considering its rapid reset and improved safety in the engaged state, refer to... Figure 3 The first component 1 is also equipped with an elastic element 4 that can act on the push button 3. The elastic element 4 can be designed in various forms, such as springs, spring sheets, etc. In this embodiment, a spring that is easy to install is preferred. Since the second hook 231 and the first hook 31 are arranged to hook together, the spring can provide an upward force to the first hook 31, so that the first hook 31 and the second hook 231 are always kept in a firmly hooked state to enhance the reliability of the safety switch.

[0037] For easy alignment with the push button 3 and the first hook 31, and also for convenient arrangement of the second hook 231 and the joint on the second component 2, please refer to... Figure 4 and Figure 5 The second component 2 includes a base 21 and a locking plate 22 connected to the base 21 and engaging with the push button 3. The engaging portion and the second hook portion 231 on the second component 2 are both located on the locking plate 22. In this embodiment, the base 21 and the locking plate 22 are integrally molded, simplifying the assembly process. The locking plate 22 is made of non-metallic materials such as plastic, allowing it to slightly shift left or right by its own elasticity, moving closer to or away from the push button 3. Furthermore, the locking plate 22 integrates the aforementioned engaging portion and the second hook portion 231, which can respectively cooperate with the engaging portion on the first component 1 and the first hook portion 31 on the push button 3 to achieve locking and engagement, ensuring that the first component 1 and the second component 2 will not easily open or unlock when locked.

[0038] For easier operation, please refer to... Figures 6 to 8The push button 3 is also provided with a first inclined surface 32 facing the locking plate 22. The first inclined surface 32 makes the thickness of this part of the push button 3 gradually thin from top to bottom. The mating end of the locking plate 22 (i.e. the end where the locking plate 22 and the push button 3 are close to each other) is designed with a second inclined surface 232 corresponding to the first inclined surface 32. When the first hook 31 and the second hook 231 are engaged, the first inclined surface 32 and the second inclined surface 232 are in contact. When unlocking is required, the push button 3 continues to slide towards the locking plate 22 (i.e., continues to slide downward), so that the first hook 31 on the push button 3 and the second hook 231 on the locking plate 22 disengage and separate. At the same time, through the cooperation of the first inclined surface 32 and the second inclined surface 232, the push button 3 can apply a force to the locking plate 22 to the side away from the push button 3 (i.e., outward) during the sliding process, thereby realizing the unlocking at the same time as opening the safety switch (the disengagement of the first hook 31 and the second hook 231). The angle α between the first inclined surface 32 and the vertical direction is preferably 30° to 45°. Otherwise, when the angle of the first inclined surface 32 is less than 30°, the sliding stroke of the push button 3 is longer, affecting the unlocking efficiency. When the angle of the first inclined surface 32 is greater than 45°, the user will have to exert more effort when pressing down. Therefore, the angle α of the first inclined surface 32 can be 30°, 35°, 40° or 45°. In this embodiment, the preferred angle α of the first inclined surface 32 is 30°, which can make the sliding stroke of the push button 3 shorter, improve the unlocking efficiency, and also make it easy to operate. Furthermore, the first inclined surface 32 is provided with two rods 33 extending towards the lock plate 22, and the first hook 31 is located on the corresponding rod 33. In addition, the outer side of the rod 33 is designed with a lug 35 that abuts against one end (upper end) of the elastic member 4, and the other end (lower end) of the elastic member 4 abuts against the first component 1.

[0039] refer to Figure 3 and Figure 5 In this embodiment, the joint on the first component 1 is configured as a first protrusion 11, which is located in the recessed area 12 and between the two first hook portions 31. The joint on the second component 2 is designed as a second protrusion 23. By engaging the first protrusion 11 and the second protrusion 23, the push button 3 and the locking piece 22 are tightly engaged in the locked state. Specifically, the bottom surface of the second protrusion 23 is tightly engaged with the top surface of the first protrusion 11, and the bottom surface of the second protrusion 23 has grooves on both sides to form the second hook portion 231.

[0040] To facilitate locking, the first hook 31 is designed with a third inclined surface 311 facing the second hook 231, and the second hook 231 is designed with a fourth inclined surface 2311 that cooperates with the third inclined surface 311. When the first protrusion 11 and the second protrusion 23 begin to press against each other, the fourth inclined surface 2311 can press against the third inclined surface 311, thereby compressing the elastic member 4 and causing the first hook 31 to slide downwards and engage with the second hook 231. Thus, during locking, there is no need to push the push button 3; after locking, the first hook 31 and the second hook 231 automatically engage, ensuring a reliable locking state for the two joints.

[0041] Preferably, the first protrusion 11 is also designed as a U-shaped structure with the opening 111 facing the downward sliding direction of the push button 3. This allows the push button 3 to slide along a specified path under the guidance of both sides of the first protrusion 11, avoiding deviation. At the same time, this U-shaped structure also allows the first protrusion 11 itself to have a certain elasticity, so as to smoothly press and fit with the second protrusion 23.

[0042] To ensure the strength of push button 3 without hindering its sliding, please refer to... Figure 2 and Figure 5 The push button 3 is also provided with a relief groove 34 for the first protrusion 11 to pass through. By providing the relief groove 34, interference between the push button 3 and the first protrusion 11 can be prevented.

[0043] The working principle of the locking structure of the lamp in this embodiment is as follows: When the lamp is locked and the safety switch is open, and unlocking is required, the user slides the push button 3 downwards and compresses the elastic element 4. At this time, the first hook 31 and the second hook 231 disengage, thereby releasing the safety. Simultaneously, the first inclined surface 32 on the push button 3 contacts the second inclined surface 232 on the locking plate 22. As the push button 3 continues to slide down, the second inclined surface 232 is pressed, thereby moving away from the push button 3 in a direction (e.g., Figure 7 The first protrusion 11 disengages from the second protrusion 23 (to the right), releasing the clamping force between them. The first component 1 (handle 7) and the second component 2 (base 8) are then unlocked. Afterward, the first component 1 (handle 7) can be flipped to the left relative to the second component 2 (base 8) (or the second component 2 can be rotated downwards relative to the first component 1), as... Figure 2 As shown, when the user releases the push button 3, the push button 3 slides upward to reset under the restoring force of the elastic element 4, and the locking piece 22 also resets under its own elasticity.

[0044] When locking is required, as the second component 2 (i.e., the base 8) rotates upward toward the first component 1 (or the first component 1 rotates downward toward the second component 2), the second protrusion 23 on the locking piece 22 is tightly engaged with the first protrusion 11. At the same time, the fourth inclined surface 2311 on the second hook 231 presses against the third inclined surface 311 on the first hook 31, causing the push button 3 to slide the first hook 31 downward and compress the elastic element 4 until the first hook 31 slides below the second hook 231. Under the restoring force of the elastic element 4, the first hook 31 and the second hook 221 engage with each other. At this time, the first component 1 and the second component 2 are in a reliable locking and securing state.

[0045] Of course, when locking is required, force can be applied to the push button 3 in advance to make the first hook 31 slide downward in advance. After the second protrusion 23 on the locking piece 22 is tightly engaged with the first protrusion 11, the push button 3 can be released. Similarly, at this time, under the restoring force of the elastic element 4, the first hook 31 and the second hook 221 hook each other, and the first component 1 and the second component 2 are in a reliable locking and safety state.

[0046] Example 2:

[0047] This embodiment is basically the same in structure as Embodiment 1, the only difference being the structure of the locking piece 22 and the seat 21. (Refer to...) Figure 9 and Figure 10 The locking plate 22 is hinged to the base 21 via a pin 5, allowing the locking plate 22 to move in a direction away from or towards the push button 3. A torsion spring 6 is mounted on the pin 5, with one end of the torsion spring 6 connected to the pin 5 and the other end connected to the locking plate 22, ensuring that the locking plate 22 always has a directional... Figure 9 Rotating to the left allows for quick reset of the locking plate 22, while in the locked state, it helps to keep the joint between the first component 1 and the second component 2 tightly fitted.

[0048] Its working principle is the same as that of the above embodiments, and will not be repeated here.
