Abstract

The utility model provides a mobile phone with a pressing type lock catch, which comprises a casing, a battery cover, a buckle seat and a pressing buckle. A buckle seat groove is arranged on the buckle seat; and a spring is sleeved on the buckle seat column in the buckle seat groove. The mobile phone is characterized in that the spring is a helical conical compression spring; and the end with large diameter of the spring is positioned at the bottom part of the buckle seat groove and realizes the slight interference fit with the side wall of the buckle seat groove. The cone angle of the helical conical compression spring is 9 to 10 DEG. The bottom part of the buckle seat is symmetrically provided with two sliding supporting ribs at two side positions of the buckle seat groove. Because the radial deformation of the conical compression spring is small and the spring depends on the clamping force of the side wall of the buckle seat groove to stabilize the position of the buckle seat, the loosing due to elasticity and the clamping are difficult to generate during the installation, the assembly operation is convenient, and the production efficiency is high. The sliding supporting ribs at the bottom part of the buckle seat not only increases the self strength of the buckle seat but also reduces the friction resistance force with the casing, so the movement of the buckle seat relative to the casing is smoother to be beneficial for improving the hand feeling of pressing the pressing buckle.
