Description

Positioning means

technical field

The invention relates to a positioning device, which belongs to the field of mechanical and electronic equipment, and specifically belongs to the technical field related to positioning in the mechanical part of a computer.

Background technique

In order to facilitate maintenance, testing, replacement of components or multiple devices sharing a case, many electronic devices often design the case as a removable type, so that the electronic devices contained in the case can be easily replaced or shared with other devices, etc. , such as measuring equipment commonly used in industrial instruments, or hard disks used in industrial computers, etc.; however, the general removable chassis is designed to make the extracted electronic devices easy to move and replace, and most of them are designed with inner rail slots for removable electronic devices. The two sides of the device can be directly slid into the groove of the inner rail, so that the removable electronic device is stably fixed in the case.

Since this type of electronic device has more frequent plugging and unplugging actions (because the withdrawable electronic device can be used independently for the equipment to be connected after being drawn out), and the width of the inner rail groove is larger than the width of the withdrawable electronic device, it is easy to extract After the electronic device is inserted into the groove of the inner rail, there will be deviation and shaking from side to side. In order to avoid such situations, screws are usually locked on the outer side of the inner rail groove toward the removable electronic device for fixing. However, this kind of The electronic equipment used for frequent plugging and unplugging is no longer suitable for screw locking, and the conventional removable electronic device cannot be positioned at a specific position when it moves in the chute, and other pins need to be used for positioning. When the withdrawable electronic device is moved to a specific position, insert the pin so that the withdrawable electronic device does not move anymore, but the above positioning method of the pin is not really helpful to the user, because the pin is a separate object , easy to lose and even some pins have sharp points that can stab the human body, which is very easy to cause accidental injuries. Therefore, how to solve the above-mentioned common problems and deficiencies is the direction that relevant manufacturers in this industry want to study and improve. .
