Problems solved by technology

[0006] However, in order to form the concave portion 204 or the step 209 on the inner surface 208 of the side frame 207 of the conventional base cover 201, a plurality of slide cores (slide cores) are used in the molding of the metal mold, so the molding cost will increase.
In addition, after the metal mold is formed, the concave portion 204 or the step 209 is formed through a cutting process, and since the cutting process is required, there is still a problem that the manufacturing cost increases.

Abstract

The invention provides a base cover, a base and a base structure capable of inhibiting increase of manufacturing cost without need of a plurality of sliding cores during forming metal molds. The base structure (30) is assembled by the base cover (10) and the base (20). The inner side of a side frame on the upper side of the base cover (10) is in a taper shape the ear opening of which is narrowed towards the opening side, the inner side of a side frame on the lower side of the base cover (10) is in a taper shape the ear opening of which is broadened towards the opening side, a nicking shaped cove locked with the locking jut of the base at the side frame on the lower side of the base cover (10).

Description

technical field [0001] The present invention relates to a base cover, a base, and a base structure suitable for, for example, a door handle, which can be manufactured through simple steps in die molding. Background technique [0002] An example of a conventional door handle mounting structure is shown in Figure 24, which has: a disc-shaped first base 101, which is arranged on an outer surface 161 of a door 106 and is provided with a screw sleeve 104; Seat 102, it is arranged on the other outer surface of door 106 corresponding to pedestal 101; 2 screws 103, it passes through the screw hole 122 of the 2nd pedestal 102 and the threaded hole that the screw of screw cover 104 is screwed on The first pedestal 101 and the second pedestal 102 are connected together by screwing together; a pair of door handles not shown, one is arranged on the outer surface of the first pedestal main body 101, and the other is arranged on the second pedestal 102 and connected to each other through ...
