Drawings

FIG. 1 is a schematic structural diagram of a latch device for a retractable wind turbine blade transport vehicle according to the present invention.

FIG. 2 is a right side view of a latch assembly for a telescoping wind blade transporter of the present invention.

As shown in the figure: 1. the pin comprises a pin body, 2, a pin seat, 3, a notch, 4, a handle, 5, a chain plate, 6, a return elastic piece, 7, an ear plate, 8, a fixed object, 9, a bolt, 10 and a nut.

Detailed Description

The following description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention, and the present invention is further described with reference to the accompanying drawings and embodiments.

Example 1, see FIGS. 1-2: comprises a pin body 1 and a pin seat 2 capable of inserting and fixing the pin body 1. The pin boss 2 is fixedly mounted on a fixed object 8. The pin body 1 is a rectangular cylinder, the surface of the pin body is provided with two notches 3 used for clamping the opening edge of the pin seat 2, and the notches 3 are in the shape of a cubic groove and are respectively positioned at the upper side and the lower side of the pin body 1. In order to ensure that the movement of other objects is not influenced when the pin body 1 is clamped at the edge of the pin seat 2 through the notch 3, the distance from the notch 3 on the pin body 1 to the end head of the free end of the pin body 1 is smaller than the depth of the pin seat 2, namely the free end of the pin body 1 can be completely immersed into the pin seat 2.

The right end of the pin body 1 is hinged with a handle 4, and the handle 4 can be pulled rightwards to pull out the pin body 1. The upper end of handle 4 is equipped with link joint 5, the right-hand member of link joint 5 with handle 4 is articulated, and the left end is articulated and is equipped with otic placode 7, otic placode 7 is for fixed setting up hinge seat form on the fixed object 8, it is located pin boss 2 top. Handle 4 passes through the articulated fixed object 8 of link joint 5, and link joint 5 has been 4 greatly increased home range for handle 4 can upwards or move down when moving right, drives the round pin body 1 through the structural style of many connecting rods and moves, can conveniently make the breach 3 joint of round pin body 1 at the opening part of key seat 2.

The round pin body 1 still need can keep fixed position in key seat 2 and prevent to loosen and take off, consequently this scheme has adopted return elastic component 6 to provide the pretightning force to the round pin body 1 to realize spacingly through breach 3 or handle 4. Specifically, the return elastic member 6 is a spring, and two ends of the return elastic member are respectively connected to the handle 4 and the fixed object 8. The joint of the return elastic element 6 and the handle 4 is positioned in the center of the handle 4, and the chain plate 5 and the return elastic element 6 are respectively positioned at the upper side and the lower side of the pin seat 2, so that the structure is more compact, and the position of the pin body 1 can be stable.

In this embodiment, the hinge joint is formed by using a bolt 9 as a hinge shaft and limiting the position by using a nut 10.

When the fixing device is used specifically, the fixing object 8 and another object are inserted and fixed through the pin body 1. When the unlocking is needed, the pin body 1 can freely stretch out and draw back in the rectangular hole of the pin base 2 by pulling the handle 4. Pulling handle 4 and lifting to the right side can make the breach 3 joint of the upside of round pin body 1 at the upper edge of round pin seat 2, and the shrink of return elastic component 6 makes its rigidity, and in this moment round pin body 1 retracted round pin seat 2, can not influence other object activities. When the bolt is required to be used for locking, the handle 4 is pulled rightwards and pressed downwards, so that the pin body 1 is inserted into the pin seat 2, and the fixed object 8 and another object can be locked.

The present invention and its embodiments have been described above, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the utility model as defined by the appended claims.
