Description

File holder

The invention relates to a document holder. The present invention is based on a Chinese utility model patent application filed on July 27, 2011, and the application number is 201120269248.X, the content of which is incorporated herein by reference.

The existing document holder includes a bottom plate, a platen, a handle, a torsion spring, a rotating shaft, and two rotating arms that connect the platen to the bottom plate. One end of the torsion spring is a horizontally folded arm that penetrates into a small hole in the middle of the platen, and the other end is a long straight arm, which is fixed at the bottom of the handle by a hook at the bottom of the handle, and the handle and the torsion spring are fixed by the rotating shaft nail On the bottom plate, one end of the two rotating arms penetrates into the two concentric shaft holes of the bottom plate, and the other end penetrates into the two concentric holes of the side wall of the platen, so that the handle and the torsion spring are rotated as the rotating shaft For the rotary motion, the two arms can also be rotated. The shaft pin passes through one end of the side wall of the bottom plate and the two ends of the two arms. It needs to be squeezed with a tool to make the parts assembled. Parts will not come out. The operation method is as follows. When the handle is lifted and rotated around the shaft nail, the long arm of the torsion spring is also lifted at the same time, the torsion spring rotates, and the cross arm of the other end of the torsion spring also rotates and rises at the same time. Since the cross arm is inserted in the small hole in the middle of the platen, the platen is also raised at the same time. That is, the handle can be lifted when the handle is lifted, and the paper document can be placed between the platen and the bottom plate; when the handle is lowered, the torsion spring rotates in the opposite direction and drives the platen to lower. When the handle is rotated to an angle of about 45 degrees with the bottom plate, the paper presser has pressed the paper against the bottom plate. At this time, the handle continues to be pressed against the restoring force of the torsion spring until the reverse side of the handle side wall is nested. The square hole in the side wall of the bottom plate makes the handle substantially horizontal and fixed in the state of the lock clip. Since the two arms of the torsion spring are pre-stressed at a certain angle, the restoring force of the torsion spring firmly holds the paper between the platen and the bottom plate. When the reverse buckle of the side wall of the handle is separated from the square hole of the side wall of the bottom plate, the handle is automatically rotated and lifted under the action of the torsion spring restoring force. When the restoring force is completely released, continue to lift the handle so that the cross arm of the torsion spring rises and the paper presser is raised up. After the paper presser is raised to the paper leaving the bottom plate, the paper can be taken out or placed.

One of the shortcomings of the above prior art solutions is that the number of components to be assembled is large, the assembly process is complicated, and the production efficiency is low; another disadvantage is that all the components are hardware and need to be plated and protected, which is neither inexpensive nor environmentally friendly.

SUMMARY OF THE INVENTION A primary object of the present invention is to provide a document holder having a simple structure and few hardware.

The document holder provided by the invention has a bottom plate, a longitudinal side of the bottom plate has an upwardly extending side wall and a torsion spring seat, and a side wall of the side wall away from the side of the torsion spring seat is provided with a hook. The torsion spring has a long straight arm and a horizontal folding arm, and the torsion spring is mounted on the torsion spring seat by an articulated shaft. One end of the connector and the top end of the side wall are hinged by a first plastic hinge. The outer contour of the paper pressing handle is substantially cubic, and is hinged on one side of the top surface and the other end of the connecting member by a second plastic hinge. The middle of the paper pressing handle has a sliding groove disposed parallel to the longitudinal direction of the bottom plate. The cross-folding arm is disposed in the chute so as to be slidable along the chute.

A further solution is that the connecting member is a plate body, and one end and the other end of the connecting member are respectively one side of the plate body and the other opposite side.

A further solution is that the plate has two pieces, which are respectively arranged on both sides of the torsion spring seat.

Another further solution is that the paper pressing handle has an inverted U-shaped strip body in cross section, and has internal reinforcing ribs in the middle, and the sliding groove is a through hole penetrating through the U-shaped side walls and the reinforcing ribs 22.

As a further improvement of the above various technical solutions, the bottom plate, the connecting member and the platen handle are integrally formed.

It can be seen from the above scheme that since the connecting piece, the bottom plate and the pressing handle are integrally formed, the injection molding mold can be formed at one time, so that the main components of the document holder can be changed into plastic parts, instead of the complicated hardware required for electroplating and assembly. When assembling, simply insert the torsion spring inserted into the chute of the paper folding handle into the torsion spring seat, and pass the hinge shaft through the spiral center of the torsion spring and the two hinge holes of the torsion spring seat and fix the shaft axially. The assembly process can be completed, the operation is simple, the production efficiency is improved, the production cost is reduced, the number of hardware pieces is reduced to only the torsion spring and the shaft nail, and even the shaft nail can be a plastic part.

As another further improvement of the above various technical solutions, there are the following differences:

The bottom plate, the connecting member and the pressing handle are independent parts; one end of the connecting member is connected with the top end of the side wall through the first fastening structure, and the other end is connected with the pressing handle through the second fastening structure, the first plastic hinge, the first The second plastic hinge is disposed on the connecting member.

A further solution is that the first fastening structure comprises a first plate body with a first check buckle hook directly connected to the first plastic hinge, and further comprising a position on the long side wall adapted to the first plate body and at a position The corresponding receiving groove further includes a check hole disposed on the side wall of the receiving groove to match the first check buckle.

A further solution is that the bottom plate, the connecting member and the pressing handle are independent parts; one end of the connecting member is connected with the top end of the side wall through the first fastening structure, and the other end is connected with the pressing handle through the second fastening structure. The first plastic hinge and the second plastic hinge are disposed on the connecting member, and the second fastening structure comprises a second plate with a second check back hook directly connected to the second plastic hinge, and further comprises a pressing handle The upper section has a flared through groove, and the bottom width of the through groove is matched with the sectional shape of the second plate body, and the inner reinforcing rib is provided with a buckle corresponding to the second check buckle.

It can be seen from the technical solution of the present invention that the bottom plate, the connecting member and the pressing handle are separate parts. Since the first plastic hinge and the second plastic hinge are connected, the first plate body only needs to be inserted into the receiving groove and the back is turned down. The hook member enters the check hole, inserts the second plate body into the through groove of the knurled section of the platen handle, and causes the check buckle to enter the buckle position, thereby connecting the main component connecting piece, the bottom plate and the pressing handle Together, it becomes a one-piece component, eliminating the complicated assembly process when using hardware, assembling the entire document holder, and also inserting the torsion spring of the cross-folding arm into the chute of the platen handle into the torsion spring seat, and The hinged shaft is passed through the spiral center of the torsion spring and the two hinge holes of the torsion spring seat and is axially fixed, so that the assembly process can be completed and the operation is simple. The production efficiency is improved, the production cost is reduced, the number of hardware parts can be reduced to only the torsion spring and the shaft nail, and even the shaft nail can be a plastic part.
