Speed reduction linkage type clamping mechanism and mobile phone support

Abstract

The invention discloses a speed reduction linkage type clamping mechanism. The speed reduction linkage type clamping mechanism comprises a bracket, wherein two transverse clamping jaws and a longitudinal clamping jaw are arranged on the bracket; the transverse clamping jaw comprises a transverse support arm; a transverse spur rack is formed at the end part of the transverse support arm; the two transverse spur racks are arranged in a staggered mode, and a driving gear is clamped between the two transverse spur racks. The two transverse spur racks are meshed with the driving gear; the longitudinal clamping jaw comprises a longitudinal support arm; a longitudinal spur rack is arranged above or below the longitudinal support arm; a reduction gear capable of rotating is arranged on the bracket; longitudinal teeth are formed on the longitudinal support arm; the longitudinal teeth are meshed with an output wheel of the reduction gear. When the driving gear rotates forwards or reversely, thetwo transverse clamping jaws are driven to be away from each other or close to each other, and the longitudinal clamping jaws are driven to slide in the longitudinal direction in a speed reduction mode through cooperation of the driving gear, the longitudinal support arm and the reduction gear. According to the speed reduction linkage type clamping mechanism, a mobile phone can be supported, the supporting action can be executed in a decelerating mode in the clamping process, and then stable and reliable linkage is achieved.

Description

technical field [0001] The invention relates to a mobile phone holder, in particular to a deceleration linkage clamping mechanism and a mobile phone holder. Background technique [0002] The mobile phone holder is a device used to clamp the mobile phone and support the mobile phone on the desktop, the center console of the car, etc. In practical applications, the mobile phone is generally only clamped by the claws on both sides of the mobile phone holder. Due to the lack of supporting parts at the lower end of the mobile phone, it is difficult to clamp the mobile phone stably. The holding parts are generally fixed, and only rely on the jaws on both sides to perform opening and clamping actions. For mobile phones of different sizes, sometimes it is necessary to lift the mobile phone up to a certain height, or sink a certain distance, for example , Most of the buttons on the side of the mobile phone are set near the upper edge of the mobile phone. When the buttons on the side...

Problems solved by technology

In practical applications, the mobile phone is generally only clamped by the claws on both sides of the mobile phone holder. Due to the lack of supporting parts at the lower end of the mobile phone, it is difficult to clamp the mobile phone stably. The holding parts are generally fixed, and only rely on the jaws on both sides to perform opening and clamping actions. For mobile phones of different sizes, sometimes it is necessary to lift the mobile phone up to a certain height, or sink a certain distance, for example , Most of the buttons on the side of the mobile phone are set near the upper edge of the mobile phone. When the buttons on the side of the mobile phone are opposite to the grippers, the mobile phone needs to be lifted up to prevent the grippers from pressing the side buttons of the mobile phone. In the prior art, due to The supporting parts of the mobile phone holder cannot be moved, which leads to the limitation of the mobile phone models that the mobile phone holder can hold, which only affects the application range of the mobile phone holder, and it is difficult to meet the application needs and market demand
