Description

Technical Field

[0001] The utility model relates to an anti-opening device, in particular to an anti-opening device applied to a steel grille. Background Art

[0002] In thermal power plant buildings, inspection holes for the inspection of auxiliary equipment are usually set on the floor. A plurality of steel grilles for covering the inspection holes are set at the top opening of the inspection holes. The plurality of steel grilles can be opened only when the auxiliary equipment needs to be inspected, so that construction personnel can enter the auxiliary equipment layer through the inspection holes to inspect the auxiliary equipment. After the inspection of the auxiliary equipment is completed, the construction personnel need to cover the inspection holes with a plurality of steel grilles to meet the daily traffic in the plant area.

[0003] At present, when auxiliary equipment needs to be repaired, in order to ensure the safety of the repair construction, the standard process for construction workers to open the steel grille is: first, they need to go to the construction management office to apply for a construction permit and receive a construction guardrail, and then set up guardrails around the inspection hole at the construction site to prevent people other than construction workers from falling and getting injured when passing through the inspection hole. The steel grille can only be opened after ensuring that the guardrail is set up properly. However, in the actual process of repairing auxiliary equipment, since multiple steel grilles are set side by side on the inspection hole and there is no anti-opening device between the multiple steel grilles, multiple steel grilles can be easily opened. In actual construction, in order to catch up with the construction progress, many construction workers do not follow the above standard process for opening steel grilles. Many construction workers open multiple steel grilles privately and enter the auxiliary equipment layer from the inspection hole to repair the auxiliary equipment without applying for a work ticket and setting up guardrails. This will pose a huge safety hazard and seriously affect the safety of construction. Summary of the invention

[0004] In order to solve the above deficiencies existing in the prior art, the utility model aims to provide an anti-opening device applied to a steel grating, so as to reduce potential safety hazards and thus improve construction safety.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: an anti-opening device applied to a steel grille, comprising a lock body with an open opening, a rotating member and an opening member, wherein one end of the rotating member is rotatably connected to the lock body, and the other end is fixed to the lock body by a locking mechanism to close the open opening of the lock body; the opening member can be inserted into the locking mechanism to release the limiting fixation between the locking mechanism and the lock body.

[0006] As a limitation of the present invention, the lock body includes a first plate member, and a second plate member and a third plate member respectively fixed on opposite sides of the first plate member, and the second plate member and the third plate member are on the same side of the first plate member.

[0007] As a further limitation of the present invention, the rotating component is a rotating plate, and the rotating plate is rotatably connected to the second plate via a rotating shaft.

[0008] As a further limitation of the present utility model, a limiting groove is provided on the third plate; the locking mechanism includes a locking seat fixed on the rotating plate and a movable block slidably connected to the locking seat and capable of being limited and fixed in the limiting groove, wherein an opening groove for inserting an opening member is provided at a position above the movable block in the locking seat, and when the opening member is inserted into the opening groove, the movable block can be separated from the limiting fixation of the limiting groove.

[0009] As a further limitation of the present invention, the movable card block is a first magnetic block, and the opening component includes an L-shaped vertical rod, a handle fixed at the end of the L-shaped vertical rod, and a second magnetic block fixed on the end of the L-shaped vertical rod away from the handle and attracted to the first magnetic block.

[0010] As a further limitation of the present utility model, a supplementary limiting component for supplementary limiting the locking mechanism is fixedly provided on the third plate.

[0011] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0012] (1) The utility model adopts a structural form that combines a lock body, a rotating member and a locking mechanism, wherein the lock body has an open mouth. The open mouth of the lock body is placed at the position of the adjacent sides of two adjacent steel grilles, and the rotating member is rotated to fix the locking mechanism and the lock body together. At this time, the open mouth of the lock body is closed, and the two adjacent steel grilles are locked together. By adopting the above method and using multiple utility models, multiple steel grilles on the inspection hole can be locked together in pairs, so that the multiple steel grilles can only be opened by using the opening member, and the opening member is kept by a dedicated person, which will force construction personnel to operate according to the standard process of opening the steel grilles, and can prevent construction personnel from opening multiple steel grilles privately, which can effectively reduce safety hazards and thus improve construction safety.

[0013] (2) The lock body in the utility model is composed of a first plate member, a second plate member and a third plate member, the rotating member adopts a rotating plate, and the locking mechanism adopts a structural form that combines a locking seat with an opening groove and a movable card block. The opening in the lock body can be closed through a simple structure, which makes it low in manufacturing cost and convenient to use. When in use, it is only necessary to rotate the rotating plate to limit and fix the movable card block with the limiting groove, and the opening on the lock body can be closed at this time. When you want to open the utility model, you only need to insert the opening member into the opening groove to release the limit fixation between the movable card block and the limiting groove, and the opening on the lock body can be opened at this time.

[0014] (3) In the utility model, the movable card block adopts a first magnetic block, and a second magnetic block is arranged on the opening member. When the opening member is inserted into the opening groove, the second magnetic block can move the first magnetic block upward. At this time, the movable card block can be separated from the limiting fixation of the limiting groove, which can effectively improve the convenience of opening the opening on the lock body.

[0015] (4) The present invention is provided with a supplementary limiting component. After the locking mechanism rotates with the rotating component and is fixed to the lock body, the supplementary limiting component can further limit and fix the locking mechanism to prevent the locking mechanism from being unable to be firmly fixed to the lock body when the inertia of the locking mechanism is too large. This can effectively improve the rationality and practicality of the structure of the present invention.

[0016] (5) After the utility model locks two adjacent steel grilles, the height of the protruding steel grille top surface is relatively small, which does not affect people's normal walking on the steel grille, further improving the practicality and rationality of the utility model.

[0017] In summary, the utility model has a simple structure, low manufacturing cost, convenient use, and strong practicality. When multiple utility models are applied to multiple steel grilles, multiple steel grilles can be locked together to form a whole. Multiple steel grilles cannot be easily opened without opening components, which can force construction personnel to operate according to the standard process of opening steel grilles, and can effectively improve the safety of construction. The utility model is suitable for use when multiple steel grilles need to be locked together. BRIEF DESCRIPTION OF THE DRAWINGS
