Ventilation door clamping device

Abstract

This invention is a ventilation door clamping device, comprising: a base having a clamping block, one side of which has a clamping surface; a guide wheel pivotally mounted on the base and corresponding to the clamping block; wherein the end of the clamping block away from the guide wheel has a guide slope connected to the clamping surface. When actually applied to a ventilation door, in the closed state of the first and second windows, the clamping block can clamp against the first and second windows, thereby enabling the first and second windows to form a stable positioning effect in the closed state.

Claims

1. A ventilation door clamping device, comprising: A base having a pressing block with a pressing surface on one side; a guide wheel pivotally mounted on the base and corresponding to the pressing block; wherein the end of the pressing block away from the guide wheel has a guide ramp connected to the pressing surface.

2. The ventilation door clamping device as described in claim 1, wherein an arc-shaped chamfer connects the clamping surface and the guide ramp.

3. The ventilation door clamping device as described in claim 1, wherein the clamping block has a side plane on the opposite side of the clamping surface, and the angle between the side plane and the guide ramp is 30 degrees to 35 degrees.

4. The ventilation door clamping device as described in claim 1, wherein the base includes a movable block and a main block, the clamping block is located on the main block, the main block has a main guide rail, the guide wheel is pivotally mounted on the movable block with the pivot part located within the main guide rail, the movable block has a positioning part, an adjusting member is movably disposed on the main block and partially located in the positioning part, and the adjusting member can drive the movable block to move relative to the main block when it is subjected to force and rotates in the forward and reverse directions.

5. The ventilation door clamping device as described in claim 4, wherein the movable block has an auxiliary support, the main block has an auxiliary guide rail, and the auxiliary support is partially located within the auxiliary guide rail.

6. The ventilation door clamping device as described in claim 4, wherein the main body has an extension, the adjusting member is movably disposed in the extension, the adjusting member has a connected threaded section and a head, a positioning nut is movably disposed in the threaded section, and the head and the positioning nut are respectively located on opposite sides of the extension.
