Description

Door frame clamping structure to prevent deformation

The present invention relates to the technical field of door frame equipment, and in particular, to a door frame clamping structure that prevents deformation.

For example, the new patent No. 542296 "Structure Improvement of Door Frame", as stated on page 7 of the patent specification, is to use the clamping space of the door frame body to provide a guide slope, and the elastic part of the clamping member is outside the A guide slope is also formed on the surface. By rotating the adjustment element pivoted in the operating space, the elastic part of the clamping member can be forced to tightly clamp the glass between the elastic parts on both sides to prevent the glass from falling off. .

As shown in the third and fourth figures, by rotating the adjusting element, the pressing part presses the base of the clamping member, causing the clamping member to move downward and guided by the guide slopes on both sides of the clamping space, so that the clamping member The elastic parts on both sides slowly squeeze inward, so that the gasket can be clamped on both sides of the glass to form a tight clamping state; however, the guide slope of the opposite clamping space will also be affected by the guide from the clamping piece. The external pushing force of the inclined plane may cause the side wall of the main body of the door frame to be stretched outward and deformed.

Although the structure of another preferred embodiment of the above-mentioned conventional patent is shown in Figure 6, a groove can be cut into the guide slope of the clamping space, and the groove can be used to insert a support member to strengthen the main body. The strength ensures that when the clamping member moves downward, the side walls of the main body will not expand outward and cause deformation; however, because the support member passing through the groove as shown in the sixth figure also passes through past the clamped glass (picture Winning No. 3), such a combined structure that must pass through the glass will obviously cause difficulties in implementation, and is essentially impossible to implement, so that it cannot solve the problem of the side walls of the main body being stretched outward and deformed.

A door frame clamping structure to prevent deformation of the present invention includes: a door frame, including two side plates and a cross-connection plate. The two side plates are integrally formed to connect both sides of the cross-connection plate and form a receiving groove opposite each other, and the two side plates are relatively convex. There are two inner buckle parts close to the notch of the accommodation slot. The inner buckle part includes an inner buckle piece and an outer protective piece connected to the side plate and protruding toward the inside of the accommodation slot; a clip guide frame is located in the accommodation slot. It includes a base plate and two side guide plates. The two side guide plates connect both sides of the base plate and form a clamping guide groove. The two side guide plates have two inclined guide sections that extend gradually toward the notch direction of the clamping guide groove. A tapered notch is formed in the clamp guide groove; a clamp component is installed in the clamp guide groove and includes two connected side clamping plates and a main plate. The protruding part, the two side splints partially extend from the tapered notch and have two external protruding buckles, and inner buckles at corresponding positions of each movable buckle group; and a plurality of bolts, which are screwed through the cross-connection plate and the base plate respectively. The spiral drives the clamp guide frame to move in the direction away from the clamp. The two inclined guide sections compress the two protruding parts to bring the two side plates closer to each other, and the two outer protruding buckle pieces fasten the two inner buckle parts to prevent the two side plates. Being stretched open and deformed.

Through the cooperation of the above structures, the present invention can spirally drive the clamp guide frame to move away from the clamp by rotating the bolt, so that when the two oblique guide sections compress the two side clamp plates and approach each other, the outer convex buckle pieces will fasten the two side plates. The inner buckle part can prevent the two side plates and the two side guide plates from being stretched and deformed due to the external pushing force from the two protruding parts of the two side splints. It is indeed progressive and can achieve the purpose and effect of this invention. .
