Rotary fixing device

Abstract

The invention provides a rotary fixing device. A through hole is formed in the bottom of a containing space in a base of the fixing device and one or more wrench portions with clamping grooves are arranged on the outer side in a protruding manner. The containing space allows a fixing portion of a positioning seat to penetrate out of the through hole. A center hole is formed in the top of the containing space of the positioning seat and allows a shaft rod to penetrate the center hole so that a telescopic rod body can move in and out of the containing space. The other side of the shaft rod is fixed to a cap head through a combination hole to be exposed out of the center hole of the positioning seat and fixedly embedded into an embedding groove of an outer sleeve. The containing space in the outer sleeve covers the positioning seat to abut against the base in a pressing manner. One or more clamping bodies are arranged on the outer side of the outer sleeve in a protruding manner to move in and out of the clamping grooves of the base. The adjacent peripheries of the outer sleeve and the base are provided with guide paths where the outer sleeve and the base can rotate relative to each other and ascend and descend.

Description

technical field [0001] The invention relates to a rotary fixing device, especially a fixing device that can be rotated up and down to adjust clamping or loosening. A positioning seat and a shaft are assembled inside the base, and the shaft is combined with the outer sleeve through the cap head. Then, a guiding path is provided on the relative periphery of the outer sleeve and the base, so as to achieve the purpose of the outer sleeve and the base rotating and lifting relative to each other by virtue of the guiding path. Background technique [0002] Press, in general, many items in daily life will be applied to positioning mechanisms such as screws or pins during the stroke of moving back and forth to achieve the positioning effect, such as drawers, cabinet panels and other items with telescopic structures, using screws or The pin allows the slide rail and the chute to move to the predetermined position, forming a temporary positioning for the user to work on the slide rail ...

Problems solved by technology

[0005] However, the limiting body B3 of the previous proposal is fixed in the accommodating groove A1 of the base A, and it is not easy to notice that the contraction side edges B31 on both sides of the limiting body B3 and the two long trimming sides B14 of the sliding rod body B13 are opposite to each other. In the state of position or misalignment, when the rotating rod head B4 is linked with the positioning rod B1 to rotate, it is necessary to distinguish the alignment of the second long trimming edge B14 of the sliding rod body B13 and the second shrinking side edge B31 of the limiting body B3 according to the hand feel, so as to form the use When the blind spot is unfavorable to the operation of the positioning device; and the positioning rod B1 is sleeved with an elastic body B2 outside the sliding rod body B13, then the sliding rod body B13 that grips the rod head B4 rotates and is linked to the positioning rod B1 is limited. When moving in the limit hole B30 of the position body B3, affected by the resistance of the elastic body B2, it is easy to form unstable states such as shaking and yaw of the positioning rod B1. When the edge B14 is in alignment with the contraction side edge B31 of the limiting body B3, the elastic body B2 will push the positioning rod B1 out of the through hole A0 of the base A with the rebound force, and the grasped rod head B4 will suddenly jump out. The gripping fingers cause the club head B4 to hit the base A, and directly hit the base A and the limiter B3. It is more likely to cause the base A to be skewed for a long time, and the positioning rod B1 cannot directly pass through the base A. The outside is not easy to align with the positioning hole C0 on the plate C, which is not conducive to the combination and fastening between the two plates C, that is, there are some defects in the actual application of the fixing device

[0006] Therefore, how to solve the problems and troubles that the alignment between the sliding rod body and the limit body of the positioning rod group of the positioning device in the previous project is difficult to distinguish, which affects the inconvenient rotation operation, and the positioning rod is affected by the rebound force of the elastic body. When positioning the rod, the rod head will collide with the base and cause skewing, which will cause trouble and lack of connection between the two plates. This is the direction that relevant manufacturers in this industry want to study and improve.
