Description

Steering adjustment mechanism

The invention relates to a steering adjustment mechanism, in particular to a technical field capable of increasing the range of universal coupling activities.

According to China's application No. 102214147, "Clamping Fixed Seat for Electronic Products", it discloses a positioning that can effectively position a smart phone or tablet on a wall or a desktop, mainly through a universal joint. The smart phone or tablet can be rotated in multiple directions. However, the universal joint of the patent case has a small range of motion, and it is difficult to provide us with the desired adjustment of the viewing position.

Therefore, there is a patent case for the "Smart Phone Assisted Positioning Device" of China No. 103223385, which can indeed improve the scope of the activity of the previous patent application. However, it will at least have two disadvantages: The magnetic absorbing member 2 is provided with an arc-shaped recess 21 for absorbing the spherical body 13 of the fixed seat 1 with a large area, but if an external force touches the smart phone or the tablet, the magnetic absorbing member 2 is provided. The ball 13 may be loose or shaken, so the magnetic attracting member 2 and the spherical body 13 have a problem of poor positioning and firmness. Second, the magnetic absorbing parts 2 are simply adsorbed on the back of the smart phone or tablet. If there is an external force touching the smart phone or tablet, or when the force is adjusted to adjust the viewing position, the smart phone or tablet may fall directly. The practicality is not good.

In view of this, the inventors finally researched and tested and finally invented The present invention is capable of simultaneously overcoming the shortcomings of the prior patents.

The invention relates to a steering adjustment mechanism, which comprises at least: a support unit having an adapter, and a top of the adapter is provided with a ball head; and a socket having a pivot hole penetrating through the two ends, the pivot hole The inner diameter is tapered from one end of the sleeve toward the other end to form a large aperture end and a small aperture end. The bottom of the adapter can be penetrated by the large aperture end of the pivot hole, and then protruded from the small diameter end, and The ball head is coupled to the pivot hole. In addition, the socket is provided with at least a gap between the inner and outer sides of the pivot hole. The notch is disposed along the axial direction of the pivot hole for connecting the ball feed head. a swinging angle of the joint portion; and a carrier mounted to the large aperture end of the sleeve.

It can be seen that the present invention is characterized in that the swinging angle of the adapter portion of the adapter head that can be aligned with the socket can be used to effectively improve the range of activities of the patent of the prior patent No. 102214147, and the ball of the present invention. The head system is coupled to the push-pull or arc-shaped pivot hole of the socket so that the ball head does not easily escape from the small aperture end of the pivot hole, thereby overcoming the problem of easy release of the patent of No. 103223385. .

Preferably, the carrier is further provided with a magnetic attraction element capable of adsorbing the ball head, and the magnetic attraction element is further provided with a sliding pad on the contact surface of the adsorption ball head for effectively positioning the ball head on the bearing sleeve and the carrier. Between the two, it is easy to shake the shortcomings of the patent No. 103223385.
