[0037] When using connecting locks to connect adjacent frame structures, in order to meet the requirements for the internal and external curved assembly of the product, such as... Figures 1-5 As shown, this utility model provides a knife gate arc lock. The knife gate arc lock includes a first fixed base 1, an angle block 2, a positioning pin 6, a second fixed base 3, and a locking assembly 4.

[0038] The angle block 2 has an arc-shaped groove, which includes a first arc-shaped groove portion 21 and a second arc-shaped groove portion 22 that are interconnected. The centers of the first arc-shaped groove portion 21 and the second arc-shaped groove portion 22 are different. A positioning pin 6 is fixedly mounted on the first fixed base 1 and passes through the arc-shaped groove. The second fixed base 3 is connected to the angle block 2. A locking component 4 is rotatably mounted on the second fixed base 3. The locking component 4 has a locked position and an unlocked position. When the locking component 4 is in the locked position, it locks the second fixed base 3 to the angle block 2. When the locking component 4 is in the unlocked position, the second fixed base 3 is separated from the angle block 2.

[0039] When using a guillotine-shaped lock to connect frames, first, according to the product's assembly requirements, adjust the positioning pin 6 to be located in the first arc-shaped groove 21 or the second arc-shaped groove 22, and adjust the angle block 2 relative to the first fixed base 1. Then, align the second fixed base 3 with the angle block 2, and use the locking assembly 4 to lock the second fixed base 3 and the angle block 2. Since the centers of the first arc-shaped groove 21 and the second arc-shaped groove 22 are different, they can be adjusted according to actual needs, thereby meeting the requirements of both inner and outer arc-shaped installations and avoiding interference or large gaps between frames.

[0040] In some embodiments, the first arc-shaped groove 21 corresponds to an inner arc mounting, and the second arc-shaped groove 22 corresponds to an outer arc mounting. The first arc-shaped groove 21 is closer to the second fixed base 3 than the second arc-shaped groove 22, and the diameter of the circle containing the first arc-shaped groove 21 is larger than the diameter of the circle containing the second arc-shaped groove 22. This arrangement allows the angle block 2 to form two rotation points, thereby enabling both inner and outer arc mounting as needed.

[0041] In some embodiments, the first arc-shaped groove 21 and the second arc-shaped groove 22 are transitioned by a circular arc portion. By providing the circular arc portion, it is easy for the positioning pin 6 to switch between the first arc-shaped groove 21 and the second arc-shaped groove 22, ensuring smooth switching.

[0042] In some embodiments, the first fixed base 1 has two ear plates 11, which are arranged opposite to each other at intervals. The angle block 2 is rotatably disposed between the two ear plates 11, and the positioning pin 6 is disposed on the ear plates 11. Specifically, a positioning pin 6 is provided on each ear plate 11, and the two positioning pins 6 are arranged coaxially. Through the above arrangement, the stability and flexibility of the angle block 2 rotating relative to the two ear plates 11 can be guaranteed.

[0043] In some embodiments, the angle block 2 has a positioning hole 23 at one end facing the second fixed base 3, and the second fixed base 3 is provided with a connecting pin 31, which is inserted into the positioning hole 23. By cooperating with the positioning hole 23, the position of the angle block 2 and the second fixed base 3 can be defined.

[0044] In some embodiments, angle scale lines are provided on the angle block 2 along the extension direction of the arcuate groove. Specifically, the angle block 2 has an inner arc scale line corresponding to the first arcuate groove 21 and an outer arc scale line corresponding to the second arcuate groove 22. This facilitates determining the angle of rotation of the angle block 2 relative to the first fixed base 1. To facilitate accurate observation of the rotation angle of the angle block 2 relative to the first fixed base 1, an indicator arrow is provided on the first fixed base 1, which can be aligned with the corresponding angle scale line.

[0045] In some embodiments, the locking assembly 4 includes a wrench 41 and a U-lock 42. The wrench 41 is rotatably mounted on the second fixed base 3, and the opening of the U-lock 42 is rotatably mounted on the second fixed base 3. A locking groove is provided at the end of the angle block 2 away from the second fixed base 3. When the locking assembly 4 is in the locked position, the U-lock 42 engages with the locking groove. Specifically, the rotation centers of the U-lock 42 and the wrench 41 do not coincide. During the rotation of the wrench 41 to the unlocked position, the wrench 41 drives the U-lock 42 to move towards the locking groove. When the U-lock 42 is in position, the middle connecting part of the U-lock 42 is engaged into the locking groove. Then, the wrench 41 is rotated in the opposite direction to the locked position. During this process, the U-lock 42 tightens and locks the angle block 2 to the second fixed base 3. Using the above method, it is possible to ensure that the angle block 2 and the second fixed base 3 can be quickly engaged or disengaged while facilitating operation.

[0046] In some embodiments, an extension 411 is rotatably provided on the wrench 41. By providing the extension 411, the length of the wrench 41 is extended, thereby facilitating user operation. After locking is completed, the extension 411 can be rotated and folded up relative to the wrench 41, thereby reducing space occupation.

[0047] In some embodiments, a connecting shaft 412 is rotatably mounted on the second fixed base 3, and the open end of the U-lock 42 passes through the connecting shaft 412 and is connected to a screw connector 413. Specifically, in this embodiment, the screw connector 413 is a nut. By adjusting the position of the screw connector 413 on the connecting shaft 412, the extension length of the end of the U-lock 42 relative to the connecting shaft 412 can be adjusted, thereby adjusting the tightness of the U-lock 42.

[0048] In some embodiments, the guillotine lock further includes an abutment component 5, which is disposed on the first fixed base 1. The abutment component 5 can abut against the angle block 2 to fix the angle block 2 in relative position to the second fixed base 3. By providing the abutment component 5, after the angle block 2 is adjusted relative to the first fixed base 1, the relative position of the angle block 2 and the first fixed base 1 can be locked, so that the relative position of the angle block 2 and the first fixed base 1 remains unchanged when the angle block 2 is subsequently docked with the second fixed base 3 or tightened using a U-lock.

[0049] In some embodiments, the abutment assembly 5 includes a latch 51, an abutment pin 52, an elastic member 53, and a locking member 54. The abutment pin 52 is slidably disposed in the first fixed base 1, and the latch 51 is rotatably connected to the abutment pin 52. The locking member 54 is slidably disposed in the first fixed base 1 and is disposed opposite to the abutment pin 52. One end of the elastic member 53 abuts against the locking member 54, and the other end of the elastic member 53 abuts against the first fixed base 1. When the latch 51 is in the abutment position, the elastic member 53 causes the locking member 54 to engage with the angle block 2. When the latch 51 is in the release position, the abutment pin 52 pushes the locking member 54 to separate from the angle block 2. Specifically, the latch 51 is designed as a cam structure. After adjusting the relative position of the angle block 2 and the first fixed base 1, the latch 51 is rotated so that when the latch 51 rotates from the release position to the abutment position, the latch 51 drives the abutment pin 52 to move away from the angle block 2, so that the abutment pin 52 releases its abutment against the locking member 54. Under the action of the elastic element 53, the locking element 54 engages with the angle block 2, thereby locking the position of the angle block 2 relative to the first fixed base 1. This configuration facilitates quick locking of the relative position of the angle block 2 with respect to the first fixed base 1.

[0050] This application also provides a frame structure, which includes a frame body and a guillotine-shaped lock as described above. The guillotine-shaped lock is disposed on the frame body. A first fixed base 1 is installed on one frame body, and a second fixed base 3 is disposed on another adjacent frame body. A locking component 4 locks the second fixed base 3 to the angle block 2 on the first fixed base 1, thereby realizing the connection between adjacent frame bodies and meeting the requirements for internal and external arc-shaped assembly of the product.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
