Description

Rotary positioning device

The invention relates to a rotary positioning device, in particular to a positioning device having two guide slopes on the top of a sleeve for a positioning block of a positioning member to rotate left and right. The positioning block is positioned at a first positioning groove or a second positioning groove by sliding up and down on the two guide slopes, synchronously driving a clamping element to move up and down to form a locking or unlocking state, and switching the locking state by sliding to achieve the purpose of saving time and labor.

With the advancement of technology, many commonly used items are fixed with screws, plugs and other positioning devices, which use positioning objects with telescopic functions to fix items (such as plates and sheet metal structures). However, when fixing objects with pointed ends and threads, such as screws, it takes a lot of effort to screw them in and fix them, and the fixing process is prone to damage and wear of the fixed objects.

However, if the screws are to be removed, secondary damage is more likely to be caused to the fixed object, and the removed screws are more likely to fall or be lost. Therefore, a positioning device that is not likely to cause damage to the fixed object, saves effort, and is not easily lost is the key point that the industry is eager to study and improve.

Please continue to refer to Figures 5 to 7, which are the front side cross-sectional view, rear side cross-sectional view and rear three-dimensional schematic view of the present invention's rotational positioning device. It can be clearly seen from the figures that in actual application, the present invention is embedded in a first plate 5 through the fixing portion 111 protruding from the bottom of the base 1, and the elastic element 44 sleeved on the rod 42 of the clamping element 4 in the base 1 pushes against the abutting portion 411 to extend the main body out of the first plate 5 to form a positioning (as shown in Figure 5). At this time, the positioning block 321 of the positioning member 3 is abutted against the first positioning groove 220 on the sleeve 2, and the present invention is to pull the positioning member 3 is rotated 90 degrees, so that the positioning block 321 at the bottom of the pulling portion 32 can be displaced upward along the guiding inclined surfaces 22 on both sides of the sleeve 2 and positioned at the second positioning groove 230 of the positioning portion 23, and the limiting surfaces 231 on both sides of the second positioning groove 230 can guide the positioning block 321 to slide into the second positioning groove 230 and not easily fall out, and the displacement of the positioning member 3 is accompanied by the upward movement of the fixing element 4, so that the main body 41 is retracted inside the storage space 120 of the base 1, and the supporting portion 411 of the main body 41 is in an elastic compression state for pushing the elastic element 44 (as shown in Figures 6 and 7).

The pull portion 32 can be pushed to allow the positioning block 321 at the bottom of the pull portion 32 to disengage from the second positioning groove 230 and slide into the first positioning groove 220 along the guide slope 22, thereby allowing the elastic element 44 that was originally in an elastic compression state to be elastically released, so that the supporting portion of the fixing element 4 is pushed to extend out of the first plate 5 by the elastic restoring force. The positioning member 3 is locked or unlocked by pushing the pull portion 32, so that the positioning device can be locked and unlocked by sliding, thereby achieving the purpose of saving time and effort.

Furthermore, the base 1 and the sleeve 2 are designed with different materials, and the sleeve 2 is sleeved outside the barrel 12 of the base 1, and the bottom of the sleeve 2 is against the top of the base 11 of the base 1, so that the base 1 and the sleeve 2 are processed by the process. The design of the shape and size can interfere with or fit each other, and thus cannot be easily separated.

The invention is mainly aimed at providing the two guide slopes 22 on the top of the sleeve 2 of the positioning device for the positioning block 321 of the positioning member 3 to rotate left and right, and by sliding up and down on the two guide slopes 22 to position in the first positioning groove 220 or the second positioning groove 230, the fixing element 4 is synchronously driven to move up and down to form a locking or unlocking state, and the main feature is to switch the locking state by sliding, so as to achieve the purpose of saving time and labor.
