Detailed Description
The present application is described in further detail below with reference to the attached drawings.
The embodiment of the application discloses enclosure guardrail locking structure of folding ladder frame, the vertical border in one side of enclosure guardrail 2 articulates on ladder frame 1, and the upper and lower both ends of opposite side all lock on ladder frame 1 through locking structure 3. Enclose the mode of pegging graft through the axle sleeve between guardrail 2 and the cat ladder frame 1, form articulated relation, be convenient for enclose the installation of guardrail and dismantle.
The locking structure 3 comprises a locking seat 4, a rotating buckle 5 and a locking rod 6. The bottom of the locking seat 4 below the guardrail 2 is welded on the ladder frame 1, and the upper end of the locking seat 4 above the guardrail 2 is welded on the ladder frame 1. The rotating buckle 5 is hinged on the locking seat 4 through a pin shaft, and the rotating buckle 5 is positioned on one side of the locking seat 4 in the thickness direction. The locking bar 6 is mounted on the guardrail 2. The locking seat 4 is provided with a locking port 41 for the locking rod 6 to be clamped in. The hinge axis of the rotating buckle 5 is in a plane vertically lower than the horizontal center line of the locking port 41. The rotating buckle 5 is used for being buckled on the locking rod 6 positioned in the locking opening 41 so as to limit the locking rod 6 to be separated from the locking opening 41.
Specifically, the both ends of check lock lever 6 all integrative the extending have connecting rod 61, weld on enclosing guardrail 2 through connecting rod 61. The locking bar 6 is driven to move towards or away from the locking seat 4 by the rotation of the guardrail 2.
The rotating buckle 5 is provided with a hook part 51, and when the hook part 51 is positioned in the locking port 41 and is buckled on the locking rod 6 under the action of gravity, the locking rod 6 is in a locking state; when the hook portion 51 is located outside the locking port 41 at the side where the additional external force acts and is separated from the locking lever 6, the locking lever 6 is in the unlocked state.
The locking seat 4 is integrally connected with a first abutting block 42 at the upper end of the locking port 41, a guiding portion 52 is arranged on the outer wall of one side of the hook portion 51 away from the hinge of the rotating buckle 5, and the guiding portion 52 is of an arc edge structure. When the upper end of the guide portion 52 abuts against the first abutting block 42, the guide portion 52 is partially located in the locking notch 41. The locking bar 6 is circular in cross-section to facilitate pushing the guide 52. When the locking rod 6 moves towards the locking opening 41, the locking rod 6 pushes the guide portion 52 to swing upwards towards the second abutting block 43 so as to be separated from the locking opening 41; when the locking rod 6 is separated from the guiding portion 52, the rotating buckle 5 swings downward under the action of gravity, and the hook portion 51 is fastened to the locking rod 6, so that the locking rod 6 is prevented from being separated from the locking opening 41.
When the locking rod 6 needs to be moved out of the locking port 41, the rotating buckle 5 is manually stirred upwards, the hook part 51 is moved out of the locking port 41, and then the locking rod 6 can be moved out.
Further, one side of the locking seat 4 away from the locking port 41 is integrally connected with a second abutting block 43; the swing range of the rotating buckle 5 is located between the first abutting block 42 and the second abutting block 43. The second abutting block 43 is parallel to the first abutting block 42, the second abutting block 43 has the same vertical length as the locking seat 4, and the second abutting block 43 can also improve the overall strength of the locking seat 4. The center of gravity of the rotating buckle 5 is always located on one side of the hinge shaft, which is deviated to the first abutting block 42, so that the locking rod 6 can automatically fall down after being clamped into the locking port 41, and the locking rod 6 is limited to be separated from the locking port 41.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
