[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0024] Reference Figure 1-4 As shown, the anti-falling platform flip cover lock buckle of the utility model comprises: a platform surface 1, a flip cover 2, a platform eye plate 3, a flip cover eye plate 4, a latch 5 and a limiting column 6; the flip cover 2, whose cover is arranged at the opening position of the platform surface 1; the platform eye plate 3, which is fixedly installed on the platform surface 1; the flip cover eye plate 4, which is fixedly installed on the flip cover 2, when the flip cover 2 is buckled on the platform surface 1, the flip cover eye plate 4 and the platform eye plate 3 are partially overlapped together; the latch 5, which passes through the overlapping part of the flip cover eye plate 4 and the platform eye plate 3, and a blocking rod 50 is connected to the outer wall of the latch 5; the limiting column 6, which is fixedly arranged on the platform surface 1, when the flip cover 2 is buckled on the platform surface 1, the blocking rod 50 contacts the limiting column 6 to realize the limiting of the latch 5.

[0025] After the flip cover 2 is buckled onto the platform surface 1, the pin 5 is inserted into the platform eye plate 3 and the flip cover eye plate 4, the pin 5 is rotated, and the blocking rod 50 is placed between the limiting column 6 and the platform eye plate 3. The limiting column 6 and the platform eye plate limit the blocking rod 20, which can prevent the pin 5 from escaping from the platform eye plate 3 and the flip cover eye plate 4, thereby improving the stability of the connection between the flip cover 2 and the platform surface 1.

[0026] In the above structure, the number of the platform eye plates 3 is two, and the platform eye plates 3 are arranged perpendicularly to the platform surface 1. The number of the flip eye plates 4 is two, and the flip eye plates 4 are arranged perpendicularly to the flip cover 2, and the flip eye plates 4 and the platform eye plates 3 are arranged in parallel. One end of the flip eye plate 4 is fixedly set on the flip cover 2, and the end of the flip eye plate 4 extending out of the flip cover 2 is overlapped with the platform eye plate 3. And the limiting column 6 is located between the two platform eye plates 3. The platform eye plate 3 and the flip eye plate 4 are both rectangular plates, and the upper end corners of the platform eye plate 3 and the flip eye plate 4 are both chamfered to avoid scratching people's hands.

[0027] In the above structure, the blocking rod 50 is made of round steel, and the axis of the blocking rod 50 is arranged perpendicularly to the axis of the latch 5. The blocking rod 50 is located between the limit column 6 and one of the two platform eye plates 3. A handle 51 is provided at one end of the latch 5 in the axial direction, and the handle 51 and the latch 5 are arranged in an "L" shape. Since the blocking rod 50 is also provided on the outer wall of the latch 5, the blocking rod 50, the handle 51 and the latch 5 are arranged in an "F" shape as a whole. The blocking rod 50, the handle 51 and the latch 5 are all made of round steel.

[0028] In the above structure, the platform eye plate 3 is welded to the platform surface 1. The flip eye plate 4 is welded to the flip cover 2. The platform eye plate 3 and the flip eye plate 4 are respectively fixed to the platform surface 1 and the flip cover 2 by welding, and the connection is stable and reliable.

[0029] In the above structure, the platform eye plate 3 is provided with a circular pin hole 1, the flip cover eye plate 4 is provided with a circular pin hole 2, and the plug 5 passes through the circular pin hole 1 and the circular pin hole 2. The processing of the circular pin hole 2 and the circular pin hole 2 ensures that the diameter is larger than the outer diameter of the plug 5, and the processing positions of the circular pin hole 2 and the circular pin hole 2 ensure that after the flip cover 2 is buckled on the platform surface 1, the circular pin hole 2 and the circular pin hole 2 are on the same straight line, so that it is convenient to insert the plug 5.

[0030] The construction process of the anti-falling platform flip cover lock buckle of the utility model is as follows:

[0031] The width of the platform eye plate 3 and the flip eye plate 4 needs to be determined according to the thickness of the flip cover 2. After cutting, they are drilled and drilled. Two identical pieces of the platform eye plate 3 and the flip eye plate 4 are made. After determining the spacing, weld the flip eye plate 4 to the flip cover 2, and weld the platform eye plate 3 to the platform surface 1; bend the round steel-shaped latch 5 into an "L" shape, pass through the four platform eye plates 3 and the flip eye plates 4, and weld a section of round steel, i.e., the stop rod 50, according to the switch stroke of the latch 5, so that the latch becomes an "F" shape, and finally weld the limit column 4 at the appropriate position. The latch 5 of this structure, such as Figure 3As shown, the blocking rod 50 and the handle 51 are respectively located on both sides of one of the platform eye plates 3, so that when the flip cover 2 is opened from the platform surface 1, the latch 5 can also be prevented from falling off the platform eye plate 3, preventing the latch 5 from being discarded at will.

[0032] The two platform eye plates 3 are used to fix the round steel-shaped latch 5, and the round steel and the limit column 6 welded on the latch 5 are used to prevent the latch from shaking and falling out.

[0033] In order to better install and fix, the thickness of the flap and the distance between the platform eye plate 3 and the flap eye plate 4 need to be determined in advance, so as to determine the size of the round steel-shaped pin 5 and the position of the limit column 6.

[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
