Description

TECHNICAL FIELD

[0001] The present invention relates to a pressing type positioning device and its driving mechanism, in particular, a positioning device and its driving mechanism for positioning two plates by pressing, wherein a shaft seat is assembled on a predetermined first plate, a sleeve of the driving mechanism is assembled on a predetermined second plate, and the sleeve of the driving mechanism and a pressing unit are assembled on the shaft seat, so that the predetermined first and second plates can be positioned or separated by operating the pressing unit. BACKGROUND

[0002] Many articles in daily life are provided with positioning mechanisms such as screws or pins to achieve positioning effect during moving. For example, articles with telescopic structure such as drawers and cabinet plates are provided with screws or pins to temporarily position the slide rails and slide grooves at a predetermined position for the user to work without moving the slide rails and slide grooves. Alternatively, devices assembled by multiple mechanisms such as desktop computers, notebook computers, industrial computers and workstations are provided with screws or pins to position the plates in a stacked state, so that the outer shell of the mechanism is provided with a plate that can be assembled and disassembled, or the multiple mechanisms can be conveniently assembled or disassembled.

[0003] Furthermore, the tips and threads of the general screws and pins can cause injury when the user accidentally touches them. When the devices, mechanisms or plates are disassembled, the screws or pins need to be completely disassembled, which often causes the problem of missing screws or pins. If the user does not have spare screws or pins, the remaining screws or pins are used for assembly, which causes the assembled mechanisms or plates to be unstable and easily loose or disengaged. After disassembling a large number of screws or pins, it is difficult to find the corresponding screws or pins for assembly and fixation. Furthermore, most of the screws or pins need to be operated by hand tools such as screwdrivers or wrenches during disassembly and assembly. The user needs to prepare many hand tools according to the type of screws or pins, which often causes the problem of unsuccessful assembly and disassembly. The above problems and defects continuously occur in actual use, which causes great inconvenience in using screws or pins for stacked positioning of plates.

[0004] The applicant of the present invention submitted a new patent application for structural improvement of a positioning device in Taiwan on November 9, 2010, with application number 99221678, and obtained a patent certificate published in Taiwan Patent Gazette on May 11, 2011, with certificate number M402972. Please refer to Figure 11 、 Figure 12As shown, the positioning device is provided with a receiving groove A1 on one side of the through hole A0 in the base A, and the positioning rod B1 of the positioning rod set B is arranged through the through hole A0. One side of the positioning rod B1 is provided with a penetrating body B11. The outer edge of the positioning rod B1 near the penetrating body B11 is provided with a stop ring B12. The stop ring B12 extends to the other side and is provided with a sliding rod body B13. The outer edge of the sliding rod body B13 is provided with two opposite long cut edges B14. A concave ring groove B15 is arranged in the middle of the sliding rod body B13. An internal screw hole B16 is arranged on the other side of the sliding rod body B13. An elastic body B2 is arranged on the sliding rod body B13. One side of the elastic body B2 abuts against the stop ring B12 of the positioning rod B1. The other side of the elastic body B2 abuts against the side surface of the limiting body B3. The limiting body B3 is fixedly arranged in the receiving groove A1 of the base A. A rectangular slot-shaped limiting hole B30 is arranged in the limiting body B3. The inner side of the limiting hole B30 is provided with two opposite contraction side edges B31. The two side long cut edges B14 of the sliding rod body B13 of the positioning rod B1 can be positioned and limited by the two contraction side edges B31 of the limiting body B3 to move and stretch. The internal screw hole B16 on the side surface of the sliding rod body B13 is locked by the screw rod B41 on one side of the rod head B4. The rod head B4 is exposed outside the base A. The positioning rod B1 is retracted into the through hole A0 by pulling the positioning rod B1 into the through hole A0 by the rod head B4. The stop ring B12 pushes the elastic body B2 to compress the limiting body B3. The sliding rod body B13 slides in the limiting hole B30 of the limiting body B3. When the concave ring groove B15 is positioned with the limiting body B3, the rod head B4 is rotated to drive the positioning rod B1 to rotate. The two side long cut edges B14 of the sliding rod body B13 are turned to be misaligned with the two contraction side edges B31 of the limiting body B3. The sliding rod body B13 is clamped at the limiting body B3. The rod head B4 is rotated to drive the sliding rod body B13 to rotate. The two side long cut edges B14 are turned to be aligned with the two contraction side edges B31 of the limiting body B3. The positioning rod B1 is moved to the outside of the through hole A0 of the base A by the elastic recovery force of the elastic body B2. The penetrating body B11 of the positioning rod B1 is exposed outside the base A.

[0005] But the front case of the limiting body B3 is fixed in the accommodating groove A1 of the base A, and it is not easy to detect the alignment or misalignment between the two side contraction side edges B31 of the limiting body B3 and the two side long cut edges B14 of the sliding rod body B13. When the rotating rod head B4 rotates together with the positioning rod B1, it is necessary to identify the alignment of the two side long cut edges B14 of the sliding rod body B13 and the two contraction side edges B31 of the limiting body B3 by hand feeling, which forms a blind spot during use and is not conducive to the operation of the positioning device. Moreover, the positioning rod B1 is externally sleeved with the elastic body B2. When the rotating rod head B4 is rotated and moves together with the sliding rod body B13 of the positioning rod B1 in the limiting hole B30 of the limiting body B3, the elastic body B2 is affected by the resistance, which easily forms an unstable state of shaking and deviation of the positioning rod B1. When the two side long cut edges B14 of the sliding rod body B13 are aligned with the two contraction side edges 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 a rebound force, so that the gripped rod head B4 suddenly jumps out of the fingers, and the rod head B4 hits the base A, directly colliding with the base A and the limiting body B3. Long time use will easily cause the base A to be skewed and the positioning rod B1 to be unable to directly pass out of the base A and be aligned with the positioning hole C0 of the plate C, which is not conducive to the combination and clamping of the two plates C, and the fixed device has some defects in actual application.

[0006] Therefore, how to solve the problems and troubles in the application and operation of the positioning device, and the troubles and defects in the assembly and positioning of the two plates, are the research and improvement directions of the related manufacturers in this industry. SUMMARY
