Description

Technical Field

[0001] This invention belongs to the field of general mechanical technology and is a hinged mechanical connection structure, specifically relating to a quick-release dual-axis hinge mechanism. Background Technology

[0002] Common hinges are used to connect two objects that can rotate relative to each other, enabling simple unfolding and folding functions. However, existing hinges can only rotate around a single pivot point, resulting in a limited connection method and a restricted rotation dimension. This significantly limits the unfolding space and position, imposes specific requirements on the shape of the hinged objects, and occupies a large amount of space when folded.

[0003] Meanwhile, existing hinges or latches have the problem of not being able to maintain a fixed position when unfolded. In addition, existing hinges or latches are not convenient or quick enough to connect to external objects.

[0004] Therefore, there is a need for a multi-purpose hinge mechanism that is highly flexible and occupies little space, capable of solving the above-mentioned series of technical problems simultaneously within a limited installation space. Summary of the Invention

[0005] The purpose of this invention is to solve the technical problems of existing hinges or hinges, such as limited functionality, inflexible use, rigid connection methods, limited opening and closing, and limited application occasions. This invention proposes a hinge mechanism that is not easily restricted by installation space, has high flexibility, wide range of uses, and comprehensive, convenient and quick application functions.

[0006] This invention provides a quick-release dual-axis hinge mechanism, which mainly includes a hinge fixing block, a hinge, an external connector, a pivot pin, a hinge pivot, and a fixing plate.

[0007] The hinge fixing block is plate-shaped, and a hinge pivot seat is provided on one side of it;

[0008] The hinge has two folded edges with a fixed included angle. One of the folded edges has a hinge pivot hole at its end, and the other folded edge has a pivot pin hole at its end.

[0009] The external connector is used to connect to external objects, and a pivot pin seat is provided on the external connector;

[0010] The fixing plate has a base plate on which a supporting plate is vertically fixed.

[0011] The hinge fixing block is mounted on the support plate;

[0012] The hinge pivot passes through the hinge pivot seat and the hinge pivot hole, and hinges the hinge fixing block and the other folded edge of the hinge.

[0013] The pivot pin passes through the pivot pin seat and the pivot pin hole, and hinges the external connector and the hinge at one of the folded edges.

[0014] Furthermore, the hinge mechanism also includes a mounting pin; a mounting pin seat is provided on the other side of the hinge fixing block; a mounting through hole or through groove that mates with the mounting pin seat is provided on the upper part of the support plate, and the mounting pin seat can pass through the mounting through hole or through groove from one side of the support plate and extend to the other side of the support plate.

[0015] Furthermore, the two folded edges have a right angle between them.

[0016] Furthermore, a limiting baffle is fixed to the top of the supporting plate, the limiting baffle being used to block and support the hinge; the hinge fixing block can be placed between the base plate and the limiting baffle.

[0017] Furthermore, the hinge mechanism also includes a hook and a spring.

[0018] Furthermore, the hook fastener is strip-shaped, with a short hook at one end; a spring fixing part is provided on the other end of the hook fastener on the same side as the extension direction of the short hook; on the other end, on the same side as the spring fixing part, a hinge seat is provided between the short hook and the spring fixing part for the mounting pin to pass through.

[0019] On the folded edge plate of the hinge with the pivot pin hole, a hole or groove is provided at the position of the short hook part of the hook member facing the hinge mechanism in the open state, which cooperates with the short hook part. A hanging platform that can cooperate with and lock the short hook part is provided in the hole or groove.

[0020] On the support plate of the substrate, a hole is provided corresponding to the position of the spring fixing part in the installation state of the hook fastener, allowing the spring to pass through;

[0021] A spring receiving cavity is provided at the position of the hinge fixing block corresponding to the spring fixing part, in which the spring can be placed.

[0022] As a further preferred embodiment, the contact surfaces of the short hook and the hanging platform are mutually inclined surfaces.

[0023] As a further preferred embodiment, the pivot pin is L-shaped; the pivot pin is configured to be able to rotate or be rotated in the pivot pin seat and the pivot pin hole, and can be pulled out.

[0024] Furthermore, the external connector and the substrate are used to connect external objects.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings:

[0041] like Figure 1-3 As shown, a quick-release hinge mechanism of the present invention mainly includes a hinge fixing block 1, a hinge 2, an external connector 4, a pivot pin 5, a mounting pin 6, a hinge pivot 7, and a fixing plate 9.

[0042] like Figure 1 As shown, the hinge fixing block 1 is plate-shaped, preferably rectangular, with a hinge pivot seat integrally formed on one side and a mounting pin seat on the other side. To enhance the load-bearing capacity of the hinge, the hinge pivot seat is preferably configured as a discrete comb shape. The mounting pin seat can also be configured as a discrete comb shape.

[0043] The hinge 2 has two flanges with a fixed included angle, preferably a right angle. One flange has a hinge pivot hole at its end, and the other flange has a pivot pin hole at its end. To enhance the hinge's load-bearing capacity, the hinge pivot hole is preferably configured as a separate comb shape that mates with the hinge pivot seat.

[0044] The external connector 4 can be of any shape and is used to connect external objects. A pivot pin seat is provided on the external connector 4. To enhance the load-bearing capacity of the hinge, it is preferable to configure the pivot pin hole and the pivot pin seat as separate, mutually cooperating comb-shaped components.

[0045] See appendix Figure 1-5 The fixing plate 9 has a base plate on which a supporting plate is vertically fixed. A limiting baffle in the shape of an angle iron is fixed to the top of the supporting plate, and the two folded edges of the limiting baffle are used to block and support the two folded edges of the hinge 2, respectively. Preferably, the supporting plate has a mounting through hole or slot that mates with the mounting pin seat, allowing the mounting pin seat to pass through the mounting through hole or slot from one side of the supporting plate and extend to the other side. The base plate can be fixed to another external object.

[0046] The hinge fixing block 1 can be placed between the base plate and the limiting baffle.

[0047] The assembly process of a quick-release hinge mechanism in this embodiment is as follows:

[0048] The hinge pivot 7 passes through the hinge pivot seat on the hinge fixing block 1 and the hinge pivot hole at the other folded end of the hinge 2, and hinges the hinge fixing block 1 and the other folded end of the hinge 2 together.

[0049] The mounting pin 6 passes through the mounting pin seat on the hinge fixing block 1, mounting the hinge fixing block 1 onto the support plate of the fixing plate 9. Alternatively, the hinge fixing block 1 can be fixed to the support plate of the fixing plate 9 by welding or riveting, in which case the mounting pin 6 is no longer needed, and the aforementioned mounting pin seat is no longer required on the hinge fixing block 1.

[0050] The pivot pin 5 passes through the pivot pin seat on the external connector 4 and the pivot pin hole at one of the folded ends of the hinge 2, hingedly connecting the external connector 4 and one of the folded ends of the hinge 2 together. The external connector 4 can rotate or not rotate around the pivot pin 5, that is, the external connector 4 can always remain parallel to the front of the large plane of the fixed plate 9, or it can be parallel to the opposite side of the large plane of the fixed plate 9, thus providing greater flexibility in use.

[0051] See appendix Figure 2-5 As shown, the operation process of a quick-release hinge mechanism of the present invention is described as follows:

[0052] exist Figure 2 In its unfolded state, such as Figure 4 As indicated by the arrow in the image, lifting the external connector 4 (or the connected external object) upwards and pushing it to the right causes the hinge fixing block 1 to rotate around the pivot pin 5 and the hinge pivot 7 simultaneously, thereby closing the hinge mechanism (along with the external object).

[0053] The distance from the mounting through hole or through slot on the support plate of the fixing plate 9 to the base plate is preferably the length of the flange of the hinge 2 connected to the hinge fixing block 1, such that when the hinge mechanism of the present invention is fully closed, the flange abuts against the support plate. At this time, when the included angle between the two flanges of the hinge 2 is a right angle, the other flange of the hinge 2 abuts against the base plate of the fixing plate 9.

[0054] exist Figure 3 In the closed state, such as Figure 5 As indicated by the arrow, lifting the external connector 4 (or the connected external object) upwards and pushing it to the left causes the hinge fixing block 1 to rotate simultaneously around the pivot pin 5 and the hinge pivot 7, thus unfolding the hinge mechanism (along with the external object). In the fully unfolded state, the limiting baffle supports the hinge 2.

[0055] Example 2

[0056] like Figure 1-5As shown, the quick-release hinge flip-locking mechanism of the present invention mainly includes a hinge fixing block 1, a hinge 2, an external connecting piece 4, a pivot pin 5, a mounting pin 6, a hinge pivot 7, and a fixing plate 9. It also includes a hook fastener 3 and a spring 8.

[0057] The hook fastener 3 is strip-shaped, with one end forming an L-shaped short hook. On the other end of the hook fastener 3, on the same side as the extension direction of the short hook, a spring fixing part is provided. This spring fixing part can be a protrusion or groove of a suitable shape. On the other end, on the same side as the spring fixing part, between the short hook and the spring fixing part, a hinge seat is provided for the mounting pin 6 to pass through. The shape of this hinge seat matches the aforementioned mounting pin seat, allowing the mounting pin 6 to pass through.

[0058] See appendix Figure 2 Alternatively, in the hinge 2, on the folded edge plate with the pivot pin hole, in the open state of the hinge mechanism, at the position facing the short hook of the hook member 3, a hole or groove is provided to mate with the short hook. A hanging platform capable of engaging and locking with the short hook is provided within the hole or groove. As a preferred embodiment, see Appendix. Figure 6 The schematic structure shows that the contact surfaces of the short hook and the hanging platform are mutually inclined surfaces.

[0059] See appendix Figure 2 Alternatively, on the supporting plate of the substrate, a hole is provided corresponding to the position of the spring fixing part in the installed state of the hook fastener 3, allowing the spring 8 to pass through.

[0060] A spring receiving cavity is provided at the position of the hinge fixing block 1 corresponding to the spring fixing part, in which the spring 8 can be placed.

[0061] In this embodiment, the structures of the external connector 4, the pivot pin 5, the mounting pin 6, the hinge pivot 7, and other components are the same as those in Embodiment 1.

[0062] The assembly process of a quick-release hinge mechanism in this embodiment is as follows:

[0063] The hinge pivot 7 passes through the hinge pivot seat on the hinge fixing block 1 and the hinge pivot hole at the other folded end of the hinge 2, and hinges the hinge fixing block 1 and the other folded end of the hinge 2 together.

[0064] The spring 8 is placed into the spring receiving cavity on the hinge fixing block 1, and the spring 8 is connected to the spring fixing part on the hook fastener 3. Then the mounting pin 6 passes through the hinge seat on the hook fastener 3 and the mounting pin seat on the hinge fixing block 1, thereby mounting the hinge fixing block 1 and the hook fastener 3 onto the support plate of the fixing plate 9.

[0065] The pivot pin 5 passes through the pivot pin seat on the external connector 4 and the pivot pin hole at one of the folded ends of the hinge 2, thereby hingedly connecting the external connector 4 and one of the folded ends of the hinge 2 together.

[0066] See appendix Figure 2-5 As shown, the operation process of a quick-release hinge mechanism of the present invention is described as follows:

[0067] exist Figure 2 In the unfolded state, first press the end of the hook 3 with the spring fixing part to release the short hook from the hinge 2. Then, as... Figure 4 As indicated by the arrow in the image, when the external connector 4 (or the connected external object) is lifted upwards and pushed to the right, the hinge fixing block 1 rotates around the pivot pin 5 and the hinge pivot 7, which can close the hinge mechanism (along with the external object). During this process, the spring 8 pushes the spring fixing part to reset the hook 3.

[0068] The distance from the mounting through hole or through slot on the support plate of the fixing plate 9 to the base plate is preferably the length of the flange of the hinge 2 connected to the hinge fixing block 1, such that when the hinge mechanism of the present invention is fully closed, the flange abuts against the support plate. At this time, when the included angle between the two flanges of the hinge 2 is a right angle, the other flange of the hinge 2 abuts against the base plate of the fixing plate 9.

[0069] exist Figure 3 In the closed state, such as Figure 5 As indicated by the arrow, lifting the external connector 4 (or the connected external object) upwards and pushing it to the left causes the hinge fixing block 1 to rotate simultaneously around the pivot pin 5 and the hinge pivot 7, thus unfolding the hinge mechanism (along with the external object). During this process, the mounting platform in the irregular hole or groove on the hinge 2 pushes the short hook of the hook fastener 3 to compress the spring 8. When the hinge mechanism unfolds to a certain angle, the mounting platform moves below the short hook, at which point the spring 8 pushes the hook fastener 3 to reset, thereby locking the hinge 2 with the hook fastener 3 and preventing the hinge mechanism of the present invention from rotating or closing arbitrarily.

[0070] In this second embodiment, the hinge mechanism with the hook fastener 3 can be used in any installation direction or at any installation angle.

[0071] Example 3

[0072] The hinge mechanism in this embodiment differs from the structure of Embodiment 1 or Embodiment 2, which only has the pivot pin 5, and is an improved preferred embodiment.

[0073] See appendix Figure 7 and 8 As shown, in this embodiment, the pivot pin 5 is L-shaped. The pivot pin 5 is configured to rotate or be rotated in the pivot pin seat on the external connector 4 and in the pivot pin hole at one of the folded ends of the hinge 2, and can be pulled out to achieve quick disassembly of the external connector 4 and the hinge 2.

[0074] The "L-shape" design facilitates the rotation and insertion / removal of the pivot pin 5, enabling quick connection or disassembly of the hinge mechanism and the external connector 4. When the pivot pin 5 is inserted, its end is rotated to the left or right to approach the external connector 4, preventing accidental removal. To disassemble the external connector 4, the pivot pin 5 is rotated, and its end is used to pull it out.

[0075] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
