Description

Fixed device

The present invention relates to a fixing device, in particular, a positioning member is combined with the bottom side of the seat of the positioning seat, and the positioning part of the positioning member is assembled with a preset first object, so that the positioning seat is composed of multiple materials with different hardnesses, so as to prevent the seat made of harder metal material from damaging or scratching the surface of the preset first object, and can effectively maintain the beauty and flatness of the surface.

Generally, when assembling objects or plates, they are locked together using positioning screws with knobs, collars and screws. The screws and collars are fixed to the first object, and the knob is rotated to lock the screws into the second object to form a preset position. After the screws are tightened with hand tools, the first object and the second object are locked and fixed together. It can be used in telecommunications cabinets, industrial computers, machine tools and other equipment composed of multiple devices and mechanisms to connect objects to objects.

Furthermore, some companies have developed a floating screw composed of a cap, a screw and a positioning seat. After the positioning seat of the floating screw is combined with the through-hole of the first object, the screw is used to lock it on the second object to form a fixation. When the user removes the first object, the floating screw can still be fixed in the through-hole of the first object through the positioning seat without causing loss. However, during assembly and actual application of the floating screw currently used, the positioning seat made of a harder metal material will scratch or damage the surface of the first object, affecting the beauty and flatness of the surface of the first object, and then causing it to break and have to be replaced. This is not cost-effective and needs to be improved.

Therefore, how to solve the above problems and deficiencies is the key that those working in this industry are eager to study and improve.

Therefore, in view of the above problems and deficiencies, the inventor collected relevant information, evaluated and considered various aspects, and used his many years of experience in this industry to continuously modify the design and finally came up with the invention patent for this type of fixing device.

The main purpose of the present invention is that the fixing device includes a positioning seat and a locking element, and the positioning seat includes a seat body and a positioning piece, the seat body has a containing space inside, and has a through hole on one side of the containing space, and a coupling portion is provided on the side of the seat body near the through hole facing the outside, and the positioning piece has a through hole inside, and a fixing portion is provided on the upper side of the positioning piece facing the outside to be fixed to the coupling portion of the seat body, and the positioning piece has a positioning portion for presetting the first object assembly below the fixing portion, wherein the seat body and the positioning piece are metal pieces of different hardness, so that the positioning seat is a structure combined by multiple materials, thereby passing through a softer The metal positioning piece is attached to the surface of the preset first object, which can prevent the harder metal base from damaging or scratching the surface of the preset first object, and can effectively maintain the beauty and flatness of the surface. In addition, when the base is assembled and actually used, the base and the positioning piece are combined into one body, thereby providing the softer metal positioning piece with better structural strength and support through the harder metal base, which can prevent the softer metal positioning piece from being deformed by force, and provide vertical pressure and tension stability when the locking element is actuated, thereby maintaining and extending the service life of the fixing device of the present invention.

Another purpose of the present invention is that the rod body and the threaded part of the locking element are movably inserted into the accommodation space and the through hole of the seat body, and the threaded part can be movably inserted out of the bottom of the through hole of the positioning member. The positioning seat assembled with the preset first object can be locked to the second object by the threaded part to form a fixation. When the preset first object is separated from the preset second object, it can be fixed to the positioning hole of the preset first object through the positioning seat without causing the loss of the fixing device of the present invention. In addition, it can be applied to industrial servers to make maintenance and replacement easier, thereby providing a quick disassembly and assembly in a machine room with many industrial servers and a large number of related parts, thereby reducing the time and manpower for maintenance and replacement.
