Description

Hidden handle type ditch cover plate Technical Field The utility model relates to the technical field of cable protection of power facilities, in particular to a hidden handle type trench cover plate. Background In the construction process of the electric power system, a cable groove is generally provided between primary equipment and secondary equipment of a substation, so that the primary equipment and the secondary equipment are connected through a cable in the cable groove. The movable cable trench cover plate is arranged on a part of the section of the cable trench so as to be opened during construction and maintenance, and inspection, maintenance and management are carried out on the cable and ponding conditions inside the cable trench. In order to ensure the flatness and the attractive appearance of the surface of the cable trench cover plate and simultaneously give consideration to the convenience of opening, a handle ring is generally adopted. The cable trench cover plate is lifted by the overhauling personnel through the handle ring, the cable trench cover plate is put down after overhauling is finished, and the handle ring is loosened, so that the cable trench cover plate falls on the surface of the cable trench cover plate again. This form is suitable for outdoor metal cable trench covers. While indoor cable trench covers, considering the flatness and aesthetic property of the ground, a tile glazed cable trench cover is generally used. However, when the handle ring falls down, the cable trench cover plate with the ceramic surface is easy to crack or collide with the glaze surface, so that the attractiveness is affected, and the replacement cost is high. Disclosure of Invention The utility model provides a hidden handle type trench cover plate, which aims to solve the problem that an indoor cable trench cover plate is easy to crack or collide when a handle ring falls down. In order to achieve the above object, the technical scheme of the present utility model is as follows: A hidden handle type trench cover comprises a cover body; The cover plate body is provided with at least one step hole, the step hole is provided with a bolt, and the step hole comprises a unthreaded hole and a threaded hole which are communicated with each other; The bolt is screwed in a state that the screw rod of the bolt is in threaded connection with the threaded hole, so that the head of the bolt can completely enter and extend out of the unthreaded hole. Further, the portable electric power tool also comprises a lifting handle, wherein the lifting handle comprises a plugboard and a handle fixed on the plugboard; The inserting plate is provided with an inserting opening, and a screw rod of the bolt can be radially inserted into the inserting opening; when the screw rod of the bolt is positioned in the socket, the bolt is screwed down, so that the head of the bolt can compress the plugboard on the cover plate body. Further, the width of the socket gradually converges from outside to inside. Further, the socket is rectangular. Further, the socket is trapezoidal. Further, the lifting device comprises two lifting handles, and two symmetrically arranged step holes are formed in the cover plate body. Further, the light source further comprises a hole plug, and the hole plug can be plugged into the light hole. Further, the cover plate body is fixedly provided with a connecting piece, the connecting piece comprises an outer edge, a first sleeve and a second sleeve which are sequentially arranged from top to bottom, the outer edge is fixed on the top surface of the cover plate body, a unthreaded hole is formed in the first sleeve, and a threaded hole is formed in the second sleeve. The beneficial effects are that: According to the hidden handle type trench cover plate, the stepped hole is formed in the cover plate body, the bolt is arranged in the stepped hole, the bolt head is completely immersed into the unthreaded hole of the stepped hole by screwing the bolt under the condition that maintenance is not needed, so that pedestrians are prevented from tripping due to carelessness, when maintenance is needed, only the bolt is unscrewed, the bolt head is exposed out of the unthreaded hole, and maintenance staff can lift the cover plate body through the bolt head.
