Description

Technical Field

[0001] The utility model relates to the technical field of protective doors, in particular to a firmly fitted protective door. Background Art

[0002] A protective door is a door that can withstand various shock waves or heavy objects. It is generally made of steel. Its function is to prevent people and objects from entering dangerous areas, or to prevent unauthorized people from entering specific areas. Protective doors are widely used in various places, such as laboratories, computer rooms, warehouses, hospitals, etc.

[0003] At present, in the prior art, a Chinese patent with announcement number CN208485471U discloses a sturdy elevator shaft protective door. The device can improve the strength and stability of the protective door body by providing a fixed plate, a round tube, a first reinforcing cavity, a second reinforcing cavity, an upper reinforcing diagonal rod and a vertical rod structure. However, in actual use, since the protective door body is not connected to a locking device to maintain the stability of the device when it is closed and fitted, the safety hazard is aggravated by wind and external influences. In view of this, we propose a firmly fitting protective door. Utility Model Content

[0006] A fixing seat, the outer wall of the protective door body is fixedly connected with the fixing seat;

[0007] A round rod, the outer wall of the fixing seat is fixedly connected with the round rod.

[0008] Preferably, one end of the round rod away from the fixing seat is fixedly connected to the lower clamping block, and the movable fit of the round rod drives the clamping of the lower clamping block.

[0009] Preferably, the protective door body is provided with two groups, one group of the protective door bodies has an outer wall fixedly connected to a fixed seat, and the other group of the protective door bodies has an outer wall fixedly connected to a limiting seat, and the fixed seat drives the round rod to move into the limiting seat.

[0010] Preferably, two groups of limit seats are provided, and the outer walls of the two groups of limit seats are fixedly connected with fixed shafts, and movable blocks are rotatably connected to the fixed shafts. The outer walls of the movable blocks are designed with inclined surfaces to facilitate the round rod to squeeze the movable blocks, so that the movable blocks rise and push the round rod into the limit seats. At this time, the inner walls of the movable blocks are in an arc shape, which fits the shape of the round rod to prevent the round rod from being displaced.

[0011] Preferably, the pressing and fixing device includes a fixing rod 1, and the outer wall of the protective door body is fixedly connected with a fixing rod 1 and a fixing rod 2. The outer wall of the fixing rod 1 is rotatably connected with a pressing plate, and the pressing plate is fixedly connected to the arc plate, and the angle of the arc plate is flipped by pressing down the pressing plate.

[0012] Preferably, the second fixing rod is slidably connected with an upper clamping block, and a sliding groove is provided on the outer wall of the upper clamping block. The rotation of the arc plate drives the movement of the upper clamping block, so that the sliding groove of the upper clamping block moves backward to release the clamping relationship.

[0013] The utility model provides a firmly fitting protective door, which has the following beneficial effects:

[0014] (1) The firmly fitting protective door is provided with a fitting device. When the two sets of protective door bodies are closed and fitted, the fixed seat on one set of protective door bodies drives the round rod to move to the inside of the limiting seat on the other set of protective door bodies. The movable fitting of the round rod drives the clamping of the lower clamping block. The outer wall of the movable block is designed with an inclined surface, which is convenient for the round rod to squeeze the movable block, so that the movable block rises and pushes the round rod into the limiting seat. At this time, the inner wall of the movable block is in an arc shape, which fits the shape of the round rod to prevent the round rod from being displaced, thereby achieving stability when the two sets of protective door bodies are fitted together and reducing the secondary risk caused by the influence of external forces on the protective door.

[0015] (2) The firmly fitting protective door is fixed by a downward pressing device. When the protective door body is fitted, in order to tighten the firmly fitting relationship, the pressing plate is pulled to drive the angle of the arc plate to flip, and the rotation of the arc plate drives the upper clamping block to move downward, and the sliding groove of the upper clamping block is pushed forward until the upper clamping block and the lower clamping block are clamped to achieve a fixing effect, and the protective door after the limit is positioned and locked, thereby improving the subsequent use effect of the protective door.
