Between the locking switching surfaces 62, the locking end of the wrench 6 is provided with a locking protrusion 64 and a guide groove. The guide rail 11 is a U-shaped flange. The center of the U-shaped flange coincides with the rotation connection point 61 of the wrench 6 and the locking block 3. The U-shaped flange has an arc-shaped bottom and a straight side. The U-shaped flange is set in the guide groove. When the locking switching surface 63 presses the steel ball 4, the locking protrusion 64 is stuck on the bottom of the U-shaped flange. When the unlocking switching surface 63 presses the steel ball 4, the locking protrusion 64 is located on the side of the U-shaped flange.
[0024] The locking block 3 has a convex track, and the guide rail 11 has a concave track, and the convex track and the concave track are slidably engaged.
[0025] The locking switching surface 63 and the unlocking switching surface 62 are arranged adjacent to each other.
[0026] The cover plate 7 restricts the upward movement space of the steel ball 4, spring 5 and wrench 6, and the cover plate 7 is fixed to the locking block 3.
[0027] The specific descriptions of each component are as follows:
[0028] Lamp Body 1: Made of AL6061-T6 material, with a hard anodized surface and black color. The outer side of the track of Lamp Body 1 has a rounded protrusion, which can be used with wrench 6 to tighten the Lamp Body 1 and locking block 3 together. The entrance of the concave track has a chamfer to prevent jamming during installation. The cavity plays a load-bearing role. The connecting part is a semi-elliptical concave track. Track 11 is an inner connection that precisely matches the surface of the convex track of locking block 3. The top of the semi-ellipse of Lamp Body 1 has a raised round step for cooperation with wrench 6 to ensure the accuracy of the product in the front and back directions. There is a circular track in the middle of the semi-ellipse for placing the waterproof ring, absorbing the height tolerance, and reducing the gap between locking block 3 and Lamp Body 1.
[0029] Cup head screw 2: made of stainless steel, with black nickel plating, and black in color. It is used to lock the locking block 3 and the adapter 8 together.
[0030] Locking block 3: Material AL6061-T6, hard anodized surface, black color; the lower surface of locking block 3 has a chamfer to prevent damage to the mating waterproof ring and to facilitate smooth connection during assembly. Two screw holes are used to tighten cover plate 7; the internal groove is used to hold spring 5 and steel ball 4, and is positioned by the mating surface of wrench 6. Locking block 3 and cover plate 7 are clamped together to ensure that wrench 6 moves in the groove. The two grooves on locking block 3 are for mating with the two forks of adapter 8 to achieve a face-to-face fit. The middle is then tightened by cup head screw 2 to fix locking block 3 and adapter 8; locking block 3 has a semi-elliptical convex track that fits face-to-face with the concave track of lamp body 1 to ensure relative sliding.
[0031] Steel ball 4: made of stainless steel, galvanized surface treatment, silver color. It rolls in the groove of locking block 3. Through the elastic force of spring 5, under the action of external force, it moves the wrench 6 to rotate around the circular hole. Using the edge of the wrench 6, the position of the wrench 6 is fixed in two variable positions.
[0032] Spring 5: made of piano wire, plated with bright nickel, small at both ends and large in the middle. The outer diameter of the two ends of spring 5 is smaller than the outer diameter of steel ball 4. More than half of spring 5 is fixed in the groove of locking block 3. The elastic force of spring 5 supports steel ball 4 and fixes the position of wrench 6 in two variable positions when the wrench 6 is turned.
[0033] Wrench 6: Material AL6061-T6, hard anodized surface, blue color; Wrench 6 has a groove where it is subjected to external force. Spring 5 supports steel ball 4. When wrench 6 is moved, the position of wrench 6 is fixed in two variable positions. When wrench 6 is in the center, it can lock the locking block 3 and the lamp body 1. When wrench 6 is moved to the side, the locking block 3 and the lamp body 1 are unlocked, and the locking block 3 can separate from the lamp body 1 along the guide rail 11.
[0034] Cover plate 7: Material AL6061-T6, hard anodized surface, black color; has three holes, two of which are chamfered, to facilitate the orientation of countersunk screws 9 onto locking block 3, used to limit the movement of spring 5, steel ball 4 and wrench 6.
[0035] Adapter 8: Material AL6061-T6, hard anodized surface, black color; it has two forked holes on the top, these two holes are relatively large, these are commonly used standard sockets for computer racks, camera racks, tripods, etc. It also has two forked holes on the bottom, one is a through hole and the other is an M3 threaded hole; during assembly, insert the two forked holes of adapter 8 into the slot of locking block 3 and the cup head screw 2, pass through the hole with cup head clearance of locking block 3, through the through hole of adapter 8, and then to the threaded hole of locking block 3. Through the upper contact surface of adapter 8 and the upper contact surface of locking block 3, as well as the side of adapter 8 and the side of locking block 3, the two surfaces mate, and with the tightening of cup head screw 2, the connection between adapter 8 and locking block is ensured.
[0036] Countersunk screw 9: Made of stainless steel, with a black nickel plating, and is black in color. It is used to fix the cover plate 7 to the lock block 3.
[0037] Waterproof ring 10: Material: 70-degree nitrile rubber, black in color, used between locking block 3 and lamp body 1 to reduce the shaking caused by the gap.
[0038] The present invention provides a quick-release structure and a lighting device having the same structure, the assembly method of which is as follows:
[0039] Place spring 5 into the spring groove of locking block 3, then place steel ball 4 into locking block 3, and place steel ball 4 into the end of spring 5 near the middle; then place wrench 6 into the groove of locking block 3, and then make an angle between the bevel of wrench 6 and the bevel of locking block 2, and slowly push wrench 6 to the corresponding round hole of locking block 3; cover with cover plate 7, and lock countersunk screw 9; insert the two prongs of the small hole of adapter 8 into the two corresponding grooves of locking block 3, pass the cup screw 2 through the screw head clearance of locking block 3, through the through hole, through adapter 8, and then through the second through hole of locking block 3, and then reach the threaded hole of adapter 8, and tighten to complete the fixing of adapter 8 and locking block 3, and complete the assembly of the locking block part. Place waterproof ring 10 into the circular track of lamp body 1 to complete the assembly of lamp body part. Move the lever 6 of the locking block to the side, align the convex slide rail of the locking block 3 with the concave slide rail of the lamp body and push it all the way down. Move the lever 6 to the center. Since the locking part can only slide back and forth, the lever 6 will lock the lamp body, thus completing the locking purpose. When locked, move the lever 6 to the side, the front and rear locking will be released, and the locking block 3 will exit along the slide rail, completing the unlocking function.
[0040] The present invention provides a quick-release structure and a lighting device having the same structure, the working principle of which is as follows:
[0041] Working principle: Spring 5 is placed into the spring groove of locking block 3, followed by steel ball 4. When wrench 6 is slowly pushed into the mating circle of locking block 3, wrench 6, under the action of spring 5 pushing the steel ball, can only remain in the starting or ending position within the mating groove of locking block 3. When wrench 6 is moved by an external force, the inclined surface of wrench 6 and the inclined surface of locking block 3 act together on steel ball 4, which in turn applies force to spring 5. At the dividing point of switching wrench 6, steel ball 4, under the pushing force of spring 5, ensures switching, locking, and unlocking through external force; simultaneously, wrench 6... The locking position aligns perfectly with the movement direction of both the locking block and the lamp body. Since the entire lamp body's track is U-shaped, when the locking block slides to the very end of the track, it cannot move forward. At this point, the lever 6 on the slider is in the center, engaging the groove in the lamp body, preventing the locking block from moving backward, thus achieving a quick-release locking function. When the lever 6 on the slider is in the unlocked position, its notch is parallel to the direction of movement, allowing the locking block to slide out along the track, completing the quick-release unlocking function. Because the locking block and lamp body are metal parts, there is a gap in their assembly. The waterproof ring compresses this gap, ensuring relative stability between the two metal parts. The adapter 8 with its two prongs and small holes is inserted into the slot of the locking block 3. The cup head screw 2 passes through the hole of the locking block 3 with the cup head clearance, through the through hole of the adapter 8, and then to the threaded hole of the locking block 3. Through the upper contact surface of the adapter 8 and the upper contact surface of the locking block 3, as well as the side of the adapter 8 and the side of the locking block 3, the two surfaces fit together. With the tightening of the cup head screw 2, the fit between the adapter 8 and the locking block 3 is ensured, and the fit between the upper and lower surfaces and the side surfaces is ensured, which more effectively fixes the product.
[0042] The quick-release structure and lighting device having the structure provided by the present invention have the following advantages:
[0043] 1. The adapter 8 with two prongs and small holes is inserted into the slot of the lock block 3. The cup head screw 2 passes through the hole of the lock block 3 with the cup head clearance, through the through hole of the adapter 8, and then to the threaded hole of the lock block 3. Through the upper contact surface of the adapter 8 and the upper contact surface of the lock block 3, as well as the side of the adapter 8 and the side of the lock block 3, the two surfaces fit together. With the tightening of the cup head screw 2, a fine fit between the top and the bottom, and between the sides of the adapter 8 and the lock block 3 is ensured.
[0044] 2. The locking block and the lamp body are engaged by the convex track of the locking block 3 and the concave track of the lamp body 1, which allows for a relatively sliding engagement.
[0045] 3. The wrench 6 rotates axially around the circular hole of the locking block 3, its range limited to the groove provided by the locking block 3; the spring 5 presses against the steel ball 4. Due to the rotation of the steel ball 4, the steel ball 4 will always stop at a point where it is subjected to force on both sides. When the steel ball 4 is in its natural state, it presses against the surface of the wrench 6 near the rotating shaft (locking switching surface 63), continuously subjected to force. The area directly above the positioning groove of the locking block 3 is also pressed against it, so this state achieves equilibrium. This is... Figure 4 The locked state; when the wrench 6 is moved by an external force, during the rotation of the wrench 6, the arc surface near the shaft, due to the compression of the spring, switches from the locked surface of the wrench 6 to the unlocked surface (i.e., the unlocking switching surface 62), that is... Figure 2 The system allows for a quick and reliable switch between locked and unlocked states.
[0046] 4. When the locking block slides from the convex guide rail of locking block 3 into the lamp body, a notch is formed in the guide groove of wrench 6. At this time, use this notch (e.g. Figure 5 The main body of the locking block slides into the groove of the lamp body. Move the lever 6 of the locking block from the side to the center to achieve the locking structure. After use, simply move the lever 6 of the locking block from the center to the side and push the locking block to complete the quick release.
[0047] 5. When the locking block slides into the lamp body, there is a certain gap due to the metal slide rail. If there is a gap, the quick-release part will wobble. Add a chamfer to the locking block 3 and the cutting entrance of the lamp body to facilitate smooth insertion. Add a waterproof ring to the lamp body to absorb the gap between the locking block and the lamp body and reduce the wobble of the quick-release structure.
[0048] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
