Technical Field

[0001] This utility model relates to the field of unloading, and in particular to a linkage locking mechanism with a limiting element. Background Technology

[0002] Currently, linkage locking mechanisms are widely used in loading and unloading operations of various goods. They securely lock the goods to the transport platform, ensuring the stability and safety of the goods during transportation. However, unlocking requires unlocking one by one, which is very inconvenient. At the same time, existing linkage locking mechanisms with limiters use straight rods, which are difficult to apply to complex terrain with obstacles, seriously affecting loading and unloading efficiency. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the current linkage locking mechanism with limiting components, this utility model can achieve synchronous unlocking and improve loading and unloading efficiency.

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

[0005] A linkage locking mechanism with limiting elements includes two mounting brackets connected by a crossbeam. Each mounting bracket houses a locking assembly. One mounting bracket houses a first limiting element, and the other a second limiting element. Adjacent locking assemblies are hinged together by a crank rod 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 crank rod. A pin passes through the through hole, allowing the first transmission component, the second transmission component, and the crank rod to rotate axially. One end of the second transmission component is connected to a locking element, which can move up and down within the locking port. The crank rod includes a left curved rod, a right curved rod, and a connecting rod. The left curved rod is connected to the right curved rod via the connecting rod. The crank rod enables the locking elements to lock or unlock synchronously.

[0006] According to one aspect of this utility model, the bending openings of both the left-side bending rod and the right-side bending rod are arranged facing upwards.

[0007] According to one aspect of the present invention, the drive device is connected to the left bending rod or the right bending rod.

[0008] According to one aspect of the present invention, the inner side of the crossbeam is provided with a groove, and a third limiting member is provided in the groove.

[0009] According to one aspect of the present invention, one end of the third limiting member is rotatably connected to the groove, and the other end is connected to the straight rod.

[0010] 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.

[0011] 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.

[0012] According to one aspect of the present invention, a washer is provided on the locking part.

[0013] According to one aspect of the present invention, the diameter of the washer is not greater than the diameter of the limiting portion.

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

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

[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 5 As shown, a linkage locking mechanism with limiting members includes two mounting brackets 6 connected by a crossbeam 61. Each mounting bracket 6 contains a locking assembly. One mounting bracket 6 contains a first limiting member 22, and the other mounting bracket 6 contains a second limiting member 23. Adjacent locking assemblies are hinged together by a crank rod 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 member 2 rotatably connected to the fixed base 1, and a second transmission member 3. The overlapping portions of the first transmission component 2, the second transmission component 3, and the crank are provided with through holes, and a pin 4 passes through the through holes. The pin 4 allows the first transmission component 2, the second transmission component 3, and the crank to rotate around their 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 crank includes a left curved rod, a right curved rod 92, and a connecting rod 93. The left curved rod is connected to the right curved rod 92 through the connecting rod 93. The crank allows several locking components 5 to lock or unlock synchronously. Traditional straight rods can easily cause some obstruction to personnel. By setting up the crank, the upper space can be utilized to prevent obstruction during loading and unloading, further improving loading and unloading efficiency.

[0026] In use, the crank is driven to the right by the drive device 7, which causes the first transmission component 2 and the second transmission component 3 to move closer to each other, and causes the locking component 5 to move downward to unlock. The crank causes the locking assembly to unlock synchronously.

[0027] In practical applications, the bends of both the left and right curved rods 92 are set facing upwards.

[0028] In practical applications, the drive unit 7 is connected to the left bending rod or the right bending rod 92.

[0029] In practical applications, the locking component 5 includes a locking part 51, a limiting part 52, and a transmission part 53 connected sequentially from top to bottom.

[0030] like Figure 6 As shown, the inner side of the crossbeam 61 is provided with a groove 62, and a third limiting member 63 is provided in the groove 62.

[0031] A limit block 531 is provided between the transmission part 53 and the mounting bracket 6.

[0032] In practical applications, one end of the third limiting member 63 is rotatably connected to the groove 62, and the other end is connected to the straight rod.

[0033] 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.

[0034] 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.

[0035] In practical applications, the diameter of washer 511 is no larger than the diameter of limiting part 52. This prevents uneven force on washer 511.

[0036] In practical applications, the drive unit 7 is a hydraulic cylinder. Using a hydraulic cylinder makes operation more convenient.

[0037] In practical applications, the first transmission component 2 includes two opposing first transmission plates 21, and the second transmission component 3 is located between the two first transmission plates 21. The transmission structure is more stable.

[0038] Specifically, a washer 511 is provided between the first transmission plate 21 and the fixed base 1. The washer 511 reduces the lateral clearance and enhances the structural stability.

[0039] In practical applications, the second transmission component 3 includes two opposing second transmission plates 31, with the crank rod positioned between the two second transmission plates 31. This results in a more robust transmission structure.

[0040] The advantages of this invention are: the locking components can be unlocked synchronously by using a crank, and it can be applied to more scenarios; the first transmission component 2 and the second transmission component 3 can move closer or further apart, thereby driving the locking component 5 to move longitudinally to achieve locking or unlocking, and the operation is simple and convenient.

[0041] 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.
