Problems solved by technology

Sometimes, especially in public places such as offices, laboratories, classrooms, etc., when it is necessary to use a trolley to transport heavy objects, it is difficult to push the heavy-duty trolley directly into the room, and the threshold becomes an obstacle; The blocking prevents part of the dirt on the ground from being swept out of the room directly.
If there is no threshold, or the threshold is buried below the ground during decoration, the door may rub against the ground when it is opened and closed, and there will be a gap under the door, and one edge is missing, which will affect the safety of the door.
Therefore, the current door frame structure with a fixed threshold wi

Example Embodiment

[0015] The detachable door frame structure of the door threshold of the present invention will be described with reference to the accompanying drawings.

[0016] like figure 1 , 2 , 3, the structure of the removable door frame structure of the threshold of the present invention is that the structure includes a door frame 1, a threshold 2, an insertion hole 3, two inserts 4 and a fixing screw 5. The left and right bottom end thresholds of the door frame 1 A socket 3 with the same shape and specification as the inner cavity of the threshold 2 is opened at the position, the two plug-ins 4 are inserted into the socket 3 to match, and the threshold 2 is clamped on the plug-in 4. It needs to be removed from the door frame 1 to form a barrier-free connection between indoor and outdoor ground.

[0017] The door sill 2 is divided into three sections, and the two end sections are groove-shaped cavity structures opened below. The two end sections of the door sill 2 and the insert 4 are...

Abstract

The invention provides a door frame structure with a detachable doorsill. The door frame structure comprises a door frame, the doorsill, inserting holes, inserting pieces and set screws. The doorsill and the inserting pieces can be dismounted from the door frame or mounted on the door frame, the inserting holes which are completely the same as the cross section of a cavity in the doorsill in size and specification are formed in the doorsill positions of the bottom ends on the left side and the right side of the door frame, the inserting pieces are rightly inserted into the inserting holes, the doorsill is mounted on the inserting pieces and is clamped, and the doorsill can be locked by the set screws. The door frame structure with the detachable doorsill has the advantages that the doorsill of the structure can be quickly dismounted and mounted according to needs, and is convenient, practical and particularly suitable for public places such as offices, laboratories, classrooms and the like. At ordinary times, the doorsill is in a mounting state and achieves a normal safety and reinforcing effect. When a floor is cleaned, a cart is used for conveying heavy objects and other special demands need to be met, the doorsill can be dismounted to enable the floors in a room and outside the room to be communicated without obstacles, cleaned objects are directly cleaned out of the room, or the heavy objects can be stably pushed into the room by the cart.

Description

technical field [0001] The invention relates to a door frame structure, in particular to a door frame structure with a detachable threshold. Background technique [0002] Present anti-theft door or safety door, the door frame is closed all around, promptly upper, lower, left and right all have edges, after installation, the lower edge is higher than the ground, is generally referred to as threshold. Sometimes, especially in public places such as offices, laboratories, classrooms, etc., when it is necessary to use a trolley to transport heavy objects, it is difficult to push the heavy-duty trolley directly into the room, and the threshold becomes an obstacle; The blocking of some ground dirt cannot be swept out of the room directly. If there is no threshold, or the threshold is buried below the ground during decoration, the door may rub against the ground when it is opened and closed, and there will be a gap under the door, and one edge is missing, which will affect the safe...
