Description

Technical Field

[0001] The invention relates to a button handle and a shower. Background Art

[0002] The child lock is a common safety switch on the shower, which can prevent children from turning on the overheated water by themselves. It generally adopts a button structure. When installing, it is necessary to first install the limit pin and the button on the temperature control handle in sequence, and then lock the temperature control handle on the valve core and valve stem of the shower with screws. Finally, use a cover plate to cover the installation port and the screw cover at the end of the handle. The above-mentioned child lock structure has the following disadvantages: 1. The installation of the cover plate causes an installation gap at the end of the handle, the handle has a poor sense of unity and texture, and the cover plate is easy to fall and lose, causing trouble to consumers; 2. After the button is first installed in the handle, when installing the limit pin, the limit pin needs to be aligned with the through hole at the bottom of the button, and the size of the through hole and the limit pin are both very small, resulting in high difficulty in installing the child lock and low installation efficiency. To this end, the present invention provides a new button handle that can solve the above technical problems. Summary of the invention
