DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0019] See also Figure 1-2The utility model is a locking mechanism for an electric skid loader, comprising a triangular crank 1, a corner in the middle of the crank 1 is hingedly connected to one of the fasteners 2 to be fastened, a corner at one end of the crank 1 is provided with a handle 3, the handle 3 and the crank 1 are integrally formed to facilitate the rotation of the crank 1, a corner at the other end of the crank 1 is hingedly connected to a slider 4, a slide rod 5 is slidably inserted on the slider 4, the cross-sectional size of the slider 4 is larger than the cross-sectional size of the slide rod 5, so as to facilitate the installation of a large spring 7, a latch 6 is hingedly connected to the end of the slide rod 5 away from the crank 1, the latch 6 is inserted into the pin hole corresponding to one of the fasteners 2 to be fastened, and the slider 4 is hingedly connected to the slide rod 5. A limiting step is provided at the end of the rod 5 away from the crank handle 1, and a large spring 7 is sleeved on the slide bar 5. The two ends of the large spring 7 are respectively squeezed on the side of the slider 4 and the limiting steps corresponding to the slide bar 5. When the slide bar 5 slides, the large spring 7 can be squeezed to compress or release. A guiding mechanism that can limit the movement of the latch 6 in the vertical direction is provided between the pin 6 and the fastener 2 to be fastened, so that the pin 6 can only move in the vertical direction, which is convenient for accurate insertion into the pin hole corresponding to the other fastener 2 to be fastened. A limiting baffle 8 that limits the swing angle of the other end of the crank handle 1 is provided on the fastener 2 on one side above the pin 6 to prevent the crank handle 1 from automatically loosening.

[0020] like Figure 2 As shown, in this embodiment, taking the example of two fasteners 2 both having pin holes, when in use, the two fasteners 2 are butt-jointed together so that their corresponding pin holes are aligned, and then the handle 3 is rotated to drive the crank 1 to swing, so that the other end of the crank 1 swings toward the side of the limit baffle 8. During the swinging process, the slider 4 drives the slide bar 5 to swing, and at the same time the slider 4 squeezes the large spring 7, and the latch 6 moves downward under the elastic force of the large spring 7, so that the latch 6 is inserted into the pin hole corresponding to the other fastener 2, so that the two fasteners 2 can be locked. When the other end of the crank 1 contacts the limit baffle 8, the large spring 7 pushes back against the slider 4, so that the other end of the crank 1 is squeezed on the limit baffle 8, so that the crank 1 will not loosen, and automatic locking is achieved; when disassembly is required, the handle 3 is rotated to drive the crank 1 to reset.

[0021] The locking mechanism of the utility model, by providing structures such as a crank handle and a spring, can achieve locking or loosening by rotating the handle, compressing and opening the spring, etc., thereby maximally ensuring the safety and stability of the connection locking and reflecting the work efficiency, thereby achieving rapid installation and assembly, and rapid disassembly and replacement of two parts, and is well applied to electric skid steer loaders.

An elastic cylindrical pin 17 is provided on the U-shaped groove, and one end of the elastic cylindrical pin 17 passes through the U-shaped groove, the latch 6, and is connected to the guide block 10. The elastic cylindrical pin 17 is interference fit with the side wall of the U-shaped groove and the guide block 10, and the elastic cylindrical pin 17 is clearance fit with the latch 6, so as to ensure that the latch 6 can rotate relative to the slide bar 5. In this embodiment, the elastic cylindrical pin 17 is used to realize the hinged connection between the slide bar 5 and the latch 6, which is more convenient for disassembly and maintenance.

[0025] Preferably, a hinge shaft 12 is provided on one side of the slider 4, and a corner of the other end of the crank 1 is hingedly installed on the hinge shaft 12. A corner of the other end of the crank 1 can be directly mounted on the hinge shaft 12 through a hole provided therein, which is very convenient for disassembly and assembly. A fixed shaft 13 is provided on the fastener 2, and a corner of the middle part of the crank 1 is hingedly installed on the fixed shaft 13. A small spring 14 and a large gasket 15 are sequentially sleeved on the fixed shaft 13 on one side of the crank 1. A locking nut 16 is also threadedly connected to the fixed shaft 13 on one side of the large gasket 15. The small spring 14 is used in conjunction with the large gasket 15 and the locking nut 16 to meet the needs of convenient disassembly and assembly, and the squeezing force on the crank 1 can also be adjusted, which is more convenient to use.
