Description

Technical Field

[0001] The utility model relates to the technical field of guide rail power supplies, in particular to a buckle structure and a guide rail electrical appliance box. Background Art

[0002] The guide rail power supply has a conductive strip inside the guide rail and a power connection piece on the electrical box. The electrical box is connected to the guide rail and can be moved to different positions on the guide rail. The power connection piece of the electrical box keeps in contact with the conductive strip to realize power supply at different positions. It is often used in guide rail lights, guide rail sockets, etc.

[0003] The existing electrical box is connected to the guide rail through a snap-fit ​​structure, such as the lock structure with publication number CN219981234U, which rotates the rotating plate by turning the toggle handle, and the first sliding groove and the second sliding groove on the rotating plate are respectively slidably connected with the first sliding column of the first claw and the second sliding column of the second claw, thereby driving the first claw and the second claw to slide closer to or away from each other; another example is the snap-fit ​​device with publication number CN220524037U, which drives the first swing arm and the second swing arm to rotate by pushing the push rod, and then drives the left slider and the right slider to slide closer to or away from each other.

[0004] The above existing buckle structure has the following problems: there are a large number of moving parts and the transmission structure is complex, which may cause the buckle movement to be uneven; in addition, the movement of the buckle claw is a horizontal sliding, and when the buckle claw is buckled with the guide rail, there may be interference and inconvenience in installation when the buckle claw and the guide rail are buckled at different heights. When the electrical box needs to be disassembled, under the gravity of the electrical box, the buckle claw hanging on the guide rail may increase the friction during horizontal sliding, resulting in uneven movement and inconvenient disassembly. Utility Model Content

[0005] The main purpose of the utility model is to provide a buckle structure and a guide rail electrical box, aiming to solve the technical problems in the prior art that the buckle structure has a large number of parts and the buckle action is not smooth enough.

[0006] In order to achieve the above-mentioned purpose, the utility model proposes a buckle structure, comprising:

[0007] Base;

[0010] When the pressing piece slides forward after sliding backward, the left and right lower pressing inclined surfaces no longer press the left and right pressing plates, and the left and right vertical plates automatically return to their original positions elastically, causing the left and right buckle parts to move closer and further away from each other to achieve buckling with the guide rail.

[0011] The buckle structure can realize the left buckle part and the right buckle part approaching or moving away from each other through the pressing piece and the buckle part, which can reduce the number of parts.

[0016] When the pressing piece is in the front position, the left opening inclined surface is on the right side of the left pressure plate, and the right opening inclined surface is on the left side of the right pressure plate. Under the action of the left opening inclined surface and the right opening inclined surface, the left pressure plate and the right pressure plate cannot be close to each other, and the left vertical plate and the right vertical plate are kept away from each other, so that the left buckle part and the right buckle part remain buckled with the guide rail without loosening, and when the pressing piece moves forward, the left opening inclined surface and the right opening inclined surface can assist in pushing the left pressure plate and the right pressure plate open to make the left vertical plate and the right vertical plate away from each other.

[0043] like Figures 1 to 13 As shown, a buckle structure includes a base 1, a buckle component 2 and a pressing component 4.

[0044] The fastener 2 includes a left vertical plate 21, a right vertical plate 22 and a lower connecting plate 23. The left vertical plate 21 and the right vertical plate 22 are spaced apart from each other. The lower connecting plate 23 is connected between the lower side of the left vertical plate 21 and the lower side of the right vertical plate 22. The left vertical plate 21, the right vertical plate 22 and the lower connecting plate 23 are roughly U-shaped. The lower connecting plate 23 is relatively fixed to the base 1. Both the left vertical plate 21 and the right vertical plate 22 can elastically swing left and right relative to the lower connecting plate 23. A left buckle 211 is provided on the left side of the upper side of the left vertical plate 21, a left pressure plate 24 is provided on the right side of the middle part of the left vertical plate 21, a right buckle 221 is provided on the right side of the upper side of the right vertical plate 22, a right pressure plate 25 is provided on the left side of the middle part of the right vertical plate 22, and the lower sides of the left pressure plate 24 and the right pressure plate 25 both have downward pressing space. Fig.12The guide rail 9 is provided with a left buckle bar 91 and a right buckle bar 92 . When buckled with the guide rail 9 , the left buckle portion 211 is buckled on the left buckle bar 91 , and the right buckle portion 221 is buckled on the right buckle bar 92 .

[0045] The pressing member 4 is arranged on the front side of the base 1, and the pressing member 4 is arranged between the left vertical plate 21 and the right vertical plate 22. The pressing member 4 is slidably connected with the base 1 along the front-to-back direction. A left lower pressing inclined surface 41 and a right lower pressing inclined surface 42 are provided on the pressing member 4. The left lower pressing inclined surface 41 is arranged on the front side of the upper side of the left pressure plate 24, and the right lower pressing inclined surface 42 is arranged on the front side of the upper side of the right pressure plate 25. The left lower pressing inclined surface 41 and the right lower pressing inclined surface 42 are both arranged to be inclined upward from the front to the back direction, so that when the pressing member 4 slides backward, the left lower pressing inclined surface 41 and the right lower pressing inclined surface 42 can respectively press the left pressure plate 24 and the right pressure plate 25 downward to drive the left vertical plate 21 and the right vertical plate 22 to approach each other.

[0046] The buckle 2 has a left vertical plate 21 and a right vertical plate 22 that can swing elastically. When the pressing member 4 is pressed backward, the left lower pressing inclined surface 41 and the right lower pressing inclined surface 42 move backward, the left pressing plate 24 abuts against the left lower pressing inclined surface 41 and slides along the left lower pressing inclined surface 41, and the right pressing plate 25 abuts against the right lower pressing inclined surface 42 and slides along the right lower pressing inclined surface 42. Therefore, the left lower pressing inclined surface 41 presses the left pressing plate 24 downward, and the right lower pressing inclined surface 42 presses the right pressing plate 25 downward. After the left pressing plate 24 moves downward, it will drive the left vertical plate 21 to swing to the right, and after the right pressing plate 25 moves downward, it will drive the right vertical plate 22 to swing to the left. At the same time, the left pressing plate 24 will also move slightly to the right, and the right pressing plate 25 will move slightly to the left. Figures 9 to 11 , so that the left buckle 211 and the right buckle 221 are close to each other and can be installed in the guide rail 9 or detached from the guide rail 9, and the left buckle 211 and the right buckle 221 can be put in or taken out from the opening of the guide rail 9, refer to Fig.13 When the pressing member 4 slides forward after sliding backward, the left lower pressing inclined surface 41 and the right lower pressing inclined surface 42 no longer press the left pressing plate 24 and the right pressing plate 25, and the left vertical plate 21 and the right vertical plate 22 automatically return to their original position. Figures 6 to 8 , so that the left buckle 211 and the right buckle 221 are separated from each other to achieve buckling with the guide rail 9, the left buckle 211 is buckled on the left buckle strip 91, and the right buckle 221 is buckled on the right buckle strip 92, refer to Fig.12 , at this time, the pressing member 4 is in the front position.

[0047] The buckle structure of this invention can realize the mutual approach or distance between the left buckle part 211 and the right buckle part 221 through the pressing member 4 and the buckle part 2, which can reduce the number of parts. The left pressure plate 24 and the right pressure plate 25 are directly pressed downward by the backward sliding of the pressing member 4 to make the left vertical plate 21 and the right vertical plate 22 swing closer to each other. When the pressing member 4 slides forward, the left vertical plate 21 and the right vertical plate 22 rebound and swing away from each other. The transmission structure is simpler and the action process is smoother. In addition, since the left vertical plate 21 and the right vertical plate 22 are swinging, the left buckle part 211 and the right buckle part 221 will move obliquely upward when they are close to each other, and will move obliquely downward when they are away from each other. Fig.12 and Fig.13 Therefore, when it is detached from the guide rail 9, it will move upward away from the guide rail 9, reducing the friction between the guide rail 9 and making the movement smoother. When it is installed with the guide rail 9, it will press downward on the guide rail 9 to reduce the corresponding requirement of height.

[0048] In some specific embodiments, referring to Figure 3 and Figure 5 A positioning groove 11 opening upward is provided on the base 1, the lower side of the left vertical plate 21, the lower side of the right vertical plate 22 and the lower connecting plate 23 are all arranged in the positioning groove 11, a positioning hole 231 is provided on the lower connecting plate 23, and a positioning column 12 is provided on the base 1, and the positioning column 12 is inserted into the positioning hole 231.

[0049] The lower side of the fastener 2 is arranged in the positioning groove 11 of the base 1, and the positioning groove 11 limits the rotation of the fastener 2. The positioning column 12 of the base 1 is inserted into the positioning hole 231 of the lower connecting plate 23, and the positioning column 12 limits the movement of the lower connecting plate 23, so as to realize the positioning of the fastener 2 in the base 1.

[0050] In some specific embodiments, the left vertical plate 21 and the lower connecting plate 23 are connected in an arc transition, and the right vertical plate 22 and the lower connecting plate 23 are connected in an arc transition. The arc transition connection can make the left vertical plate 21 and the right vertical plate 22 swing more smoothly. In other embodiments, the left vertical plate 21 and the lower connecting plate 23, and the right vertical plate 22 and the lower connecting plate 23 can also be connected in a right angle or an oblique angle.

[0051] In some specific embodiments, the pressing member 4 is provided with a left push-opening slope 43 and a right push-opening slope 44. The left push-opening slope 43 is arranged at the rear side of the right side of the left pressure plate 24, and the left push-opening slope 43 is inclined to the left along the direction from front to back. The right push-opening slope 44 is arranged at the rear side of the left side of the right pressure plate 25, and the right push-opening slope 44 is inclined to the right along the direction from front to back, so that when the pressing member 4 is located at the front position, the left push-opening slope 43 can push the left pressure plate 24 to the left, and the right push-opening slope 44 can push the right pressure plate 25 to the right.

[0052] When the pressing member 4 is located at the front position, the left opening inclined surface 43 is on the right side of the left pressing plate 24, and the right opening inclined surface 44 is on the left side of the right pressing plate 25. Figure 7 Under the action of the left push-open slope 43 and the right push-open slope 44, the left pressure plate 24 and the right pressure plate 25 cannot approach each other, and the left vertical plate 21 and the right vertical plate 22 are kept away from each other, so that the left buckle 211 and the right buckle 221 are kept buckled with the guide rail 9 and do not loosen. Moreover, when the pressing member 4 moves forward, the left push-open slope 43 and the right push-open slope 44 can assist in pushing the left pressure plate 24 and the right pressure plate 25 apart, ensuring that the left vertical plate 21 and the right vertical plate 22 are away from each other. When the pressing member 4 moves backward, the left push-open slope 43 and the right push-open slope 44 will also move backward. Fig.10 The left top opening inclined surface 43 does not hinder the left pressure plate 24 from moving to the right, and the right top opening inclined surface 44 does not hinder the right pressure plate 25 from moving to the left, so it does not affect the left buckle portion 211 and the right buckle portion 221 from approaching each other.

[0053] Further, refer to Figure 4 The pressing member 4 includes a horizontally arranged pressing plate 45, which is arranged on the upper side of the left pressing plate 24 and the right pressing plate 25, and a left pressing vertical plate 46 and a right pressing vertical plate 47 are arranged on the lower side of the front side of the pressing plate 45, a left lower pressing inclined surface 41 is arranged on the rear lower side of the left pressing vertical plate 46, and a right lower pressing inclined surface 42 is arranged on the rear lower side of the right pressing vertical plate 47. A top block 48 is also arranged on the lower side of the pressing plate 45, and the top block 48 is arranged on the rear side between the left pressing plate 24 and the right pressing plate 25, and a left top opening inclined surface 43 and a right top opening inclined surface 44 are respectively arranged on the left front side and the right front side of the top block 48. The left pressing vertical plate 46, the right pressing vertical plate 47 and the top block 48 are arranged on the lower side of the pressing plate 45, so that the structural space is more compact.

[0054] Furthermore, the right side of the left vertical plate 21 is connected to the left middle horizontal plate 241, the right side of the left middle horizontal plate 241 is extended downwardly by a left middle vertical plate 242, the lower side of the left middle vertical plate 242 is extended to the right by a left pressure plate 24, the left side of the right vertical plate 22 is connected to the right middle horizontal plate 251, the left side of the right middle horizontal plate 251 is extended downwardly by a right middle vertical plate 252, the lower side of the right middle vertical plate 252 is extended to the left by a right pressure plate 25, and the pressing plate 45 is arranged between the left middle vertical plate 242 and the right middle vertical plate 252.

[0055] The arrangement of the left middle horizontal plate 241 and the left middle vertical plate 242, the right middle horizontal plate 251 and the right middle vertical plate 252 can move the positions of the left pressure plate 24 and the right pressure plate 25 downward to install the pressing plate 45, thereby reducing the thickness of the guide rail electrical box 8, and at the same time increase the height of the force points of the left vertical plate 21 and the right vertical plate 22. When the left pressure plate 24 and the right pressure plate 25 move downward by the same distance, the left vertical plate 21 and the right vertical plate 22 can swing to a larger angle.

[0056] In some specific embodiments, the left pressing plate 24, the left lower pressing inclined surface 41 and the left top opening inclined surface 43 are symmetrically arranged with the right pressing plate 25, the right lower pressing inclined surface 42 and the right top opening inclined surface 44. In this way, the buckle 2 can be arranged to be symmetrical, which is convenient for assembly.

[0057] In some specific embodiments, the snap-fit ​​structure also includes a spring 6, which is arranged on the rear side of the pressing member 4, the front end of the spring 6 abuts against the rear side of the pressing member 4, and the rear end of the spring 6 abuts against the base 1, and the spring 6 is used to generate a forward force on the pressing member 4 after the pressing member 4 slides backward.

[0058] When the pressing member 4 is pressed to move backward, the pressing member 4 will compress the spring 6. When the pressing member 4 is released, the pressing member 4 will automatically return to its original position under the action of the spring 6, thereby simplifying the operation. In addition, the spring 6 can also keep the pressing member 4 in the front position, and when buckled with the guide rail 9, it can cooperate with the left top opening inclined surface 43 and the right top opening inclined surface 44 to maintain the position of the left buckle part 211 and the right buckle part 221 to prevent loosening.

[0059] In some specific embodiments, the buckle structure further includes an upper cover 7, which is disposed on the upper side of the base 1, and the pressing member 4 is disposed on the lower side of the upper cover 7. The upper cover 7 is provided with a left through hole 71 and a right through hole 72, and the left vertical plate 21 passes through the left through hole 71, and the right vertical plate 22 passes through the right through hole 72.
