Referring to fig. 1 to 4, the application provides a locking type anti-falling well lid, which is installed on a wellhead and comprises a lid body 10, two support legs 20 and an operating mechanism 30, wherein a movable hole 11 is formed in the lid body 10; the same ends of the two supporting legs 20 are hinged on the bottom surface of the cover body 10 and are positioned on the corresponding area of the movable hole 11, and the other ends of the two supporting legs 20 can be abutted against the well wall; the operating mechanism 30 is arranged on the top surface of the cover body 10, and the movable end movably penetrates through the movable hole 11; the movable end of the operating mechanism 30 is movably connected with the two support legs 20, and the operating mechanism 30 can control the opening degree of the two support legs 20 and lock the opening angle of the two support legs 20. Wherein, because the well lid in this application is mainly used for carrying out the lid temporarily and seals the well head, as the structure of interim protection, for this reason lid 10 can adopt wooden or plastics material to make, such design can reduce the weight of whole well lid effectively, portable. In the present application, the operating mechanism 30 has various forms as long as it can open the two support legs 20 and lock the two support legs 20. For this purpose, the operating mechanism 30 may be a screw knob structure, and the opening and closing of the two support legs 20 are controlled by the lifting and lowering of the screw, and the operating mechanism 30 may also be some telescopic driving structure, such as a telescopic motor or a telescopic cylinder. However, the telescopic driving structure is not favorable for actual field use, and the design is not preferable for the application.
Referring to fig. 1 to 3, for simplicity of design and convenience of operation, the operating mechanism 30 includes an operating rod 31 and a locking structure, the operating rod 31 is movably inserted into the movable hole 11, and a support structure 33 is disposed at a lower end of the operating rod 31; two sides of the supporting structure 33 are movably connected with the two supporting legs 20, and the locking structure is mounted on the operating rod 31 and used for locking the relative position of the operating rod 31 on the cover body 10. The operating lever 31 is of a simple design in this application, which facilitates later operation and avoids damage. In fact, in this application, when the operating rod 31 passes through the movable hole 11, the supporting structure 33 will not deform due to the body structure thereof when ascending, so as to push open two of the supporting legs 20, so that two of the supporting legs 20 abut against the well wall, thereby realizing the locking of the whole well lid and supporting the whole cover body 10. Wherein the main purpose of the locking structure is to prevent the operating rod 31 from falling, so that the locking of the opening angle of the two support legs 20 can be realized.
Further, in order to better lift the operating rod 31, in a modified embodiment of the present application, the operating portion 32 is disposed at the upper end of the operating rod 31, and the operating portion 32 is bent from the upper end of the operating rod 31, which not only facilitates the operation, but also prevents the operating rod 31 from being completely removed from the movable hole 11 in a natural manner when the locking structure is released. In one embodiment, the cover 10 is provided with a receiving groove 12 for receiving the operating portion 32, and the design is such that when the whole operating rod 31 naturally falls to the lowest point, the bent operating portion 32 is just received in the receiving groove 12, so as to prevent the operating portion 32 from protruding out of the upper surface of the cover 10.
Referring to fig. 3 and 4, in the above embodiment, the support structure 33 may be a plate-shaped structure, so that the two support legs 20 are spread apart by using both ends of the plate-shaped structure, but in order to prevent the two support legs 20 from sliding to both sides of the plate-shaped structure during spreading, the spreading direction of the two support legs 20 may be limited. To this end, in one embodiment of the present application, the support structure 33 is provided on both sides with a limiting structure for receiving two of the support legs 20, each of the two support legs 20 being slidable relative to the limiting structure.
