[0004] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0005] A linkage locking device with a limiting element includes two mounting brackets connected by a crossbeam. Each mounting bracket contains a locking assembly and a first limiting element. Adjacent locking assemblies are hinged together by a straight rod, which is connected to a driving device. The upper end of each mounting bracket has a locking port. Each locking assembly includes a fixed base, a first transmission component and a second transmission component rotatably connected to the fixed base. A through hole is provided on the overlapping portion of the first transmission component, the second transmission component, and the straight rod. A pin passes through the through hole, allowing the first transmission component, the second transmission component, and the straight rod to rotate about its axial direction. One end of the second transmission component is connected to a locking element, which can move up and down within the locking port. The straight rod enables several locking elements to lock or unlock synchronously.

[0009] According to one aspect of the present invention, the locking member includes a locking part, a limiting part, and a transmission part connected sequentially from top to bottom.

[0010] According to one aspect of the present invention, the diameter of the limiting part is larger than the diameter of the locking part or the transmission part.

[0011] According to one aspect of the present invention, a washer is provided on the locking part.

[0012] According to one aspect of the present invention, the diameter of the washer is not greater than the diameter of the limiting portion.

[0013] According to one aspect of the present invention, the first transmission member includes two opposing first transmission plates, and the second transmission member is disposed between the two first transmission plates.

[0014] According to one aspect of the present invention, the second transmission member includes two opposing second transmission plates, and the straight rod is disposed between the two second transmission plates.

[0015] The advantages of this utility model are: the driving device makes the first and second transmission components move closer or further apart, thereby driving the locking component to move longitudinally to achieve locking or unlocking, which is simple and convenient to operate; the straight rod enables several locking devices to lock or unlock synchronously; and the cooperation between the first and second limiting components makes the locking reliable.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 6 As shown, a linkage locking device with limiting components includes two mounting brackets 6 connected by a crossbeam. Each mounting bracket 6 contains a locking assembly and a first limiting component 22, which is a limiting plate located on the inner sidewall of the mounting bracket 6. Adjacent locking assemblies are hinged together by a straight rod 9, which is connected to a driving device 7. The upper end of each mounting bracket 6 has a locking port 8. The locking assembly includes a fixed base 1, a first transmission component 2 rotatably connected to the fixed base 1, and a second transmission component 3. A through hole is provided on the overlapping portion of the first transmission component 2, the second transmission component 3, and the straight rod 9. A pin 4 passes through the through hole, allowing the first transmission component 2, the second transmission component 3, and the straight rod 9 to rotate around its axial direction. One end of the second transmission component 3 is connected to a locking component 5, which can move up and down within the locking port 8. The straight rod 9 enables several locking components 5 to lock or unlock synchronously.

[0026] When in use, the locking component 5 is locked to the goods. After being pressed, the locking component 5 moves downward. The limiting support plate provides support and reduces the shaking of the locking component 5. When unlocking is required, a pulling force is applied to the drive rod, so that the first transmission component 2 and the second transmission component 3 move closer to each other, driving the locking component 5 to move downward so that the locking component 5 can switch from the locked state to the unlocked state.

[0027] In practical applications, one end of the drive device 7 is fixed to the crossbeam, and the other end is connected to the straight rod 9.

[0028] In practical applications, one end of the second limiting member 23 is rotatably connected to the crossbeam, and the other end is connected to the straight rod 9. A gap is provided between the two limiting support plates for the straight rod 9 to enter and exit.

[0029] In practical applications, the drive device 7 is a hydraulic cylinder 72.

[0030] In practical applications, the locking member 5 includes a locking part 51, a limiting part 52, and a transmission part 53 connected sequentially from top to bottom.

[0031] In practical applications, the diameter of the limiting part 52 is larger than the diameter of the locking part 51 or the transmission part 53. The limiting part 52 limits the movement of the locking member 5 to prevent it from exceeding the preset range of motion and causing wear.

[0032] In practical applications, a washer 511 is fitted onto the locking part 51. The washer 511 reduces wear and extends the product's service life.

[0033] In practical applications, the diameter of the washer 511 is not greater than the diameter of the limiting part 52. This prevents uneven force on the washer 511.

[0034] In practical applications, the first transmission component 2 includes two opposing first transmission plates 21, and the second transmission component 3 is disposed between the two first transmission plates 21.

[0035] In practical applications, the second transmission component 3 includes two opposing second transmission plates 31, and the straight rod 9 is disposed between the two second transmission plates 31.

[0036] A limit block 531 is provided between the transmission part 53 and the mounting bracket 6.

[0037] The effective effects of this utility model are as follows: the locking components are unlocked synchronously by the straight rod 9; the first transmission member 2 and the second transmission member 3 move closer or further apart, thereby driving the locking member 5 to move longitudinally to achieve locking or unlocking, which is simple and convenient to operate; the first limiting member 22 and the second limiting member 23 make the locking reliable and the structure stable; the third limiting member 10 makes the overall structure stable and improves the smoothness of the movement of the straight rod 9.

[0038] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
