Technical Field

[0001] This utility model relates to a quick-release neck structure, and more particularly to one that can strengthen the fixation of the display and the corresponding support frame, and enable quick assembly and disassembly. Background Technology

[0002] All-in-one PCs typically integrate the main unit into the monitor, which is then secured to the top of a stand via a locking mechanism on the back. This allows the monitor to stand upright on a desktop or flat surface. This method of connecting the monitor and stand via a locking mechanism is not very convenient for assembly and disassembly, requiring considerable time.

[0003] Therefore, as shown in Chinese Utility Model Patent No. CN208311828U, "A Quick-Disassembly Structure," a feasible solution is provided, which includes a rotating component. The rotating component is rotatably connected to a pivot module on the rear side of the screen. One end of the rotating component has a cantilever with an elastic portion and a downwardly extending pressing portion. A first locking portion is located below the cantilever on one side of the rotating component. A pressing element is movably positioned in the insertion groove of a support frame with a protruding pressing end. The pressing element has a second locking portion, which can engage with the first locking portion to connect the rotating component and the support frame when the cantilever of the rotating component is inserted into the insertion groove on the top side of the support frame, or to separate the rotating component from the support frame when the pressing element is pressed. The structure of the aforementioned patent CN208311828U can indeed quickly assemble the support frame and the screen; similarly, the "quick-release neck structure" of patent CN216752439U can also provide a quick assembly structure for the support frame and the screen.

The top of the support frame 4 has a roughly rectangular connecting portion 41. One side of the connecting portion 41 has a horizontally recessed rectangular groove, which serves as a recessed portion 42. Two first engaging portions (43, 43') are spaced apart on the top surface of the recessed portion 42. In practice, the first engaging portions (43, 43') are rectangular notches. Two cylinders are spaced apart in the middle of the recessed portion 42. The outer diameter of the two cylinders is smaller than the inner diameter of the two first guide grooves 25. In practice, these cylinders serve as first guide rails 44, allowing the two first guide rails 44 to correspondingly connect to the two first guide grooves 25, guiding the fixing seat 22 into and accommodating it within the recessed portion 42. Two limiting holes (45, 45') are spaced apart on the bottom surface of the recessed portion 42.

[0094] A left-bent plate 46 and a right-bent plate 47 are respectively connected to the inner side of the recess 42. The left-bent plate 46 and the right-bent plate 47 are combined to form an inner liner 48. In practice, the left-bent plate 46 and the right-bent plate 47 are made of polyoxymethylene material, and the top surface of the left-bent plate 46 and the right-bent plate 47 each has an upwardly protruding rectangular block. The two rectangular blocks serve as two second locking parts (49, 49'), and the two second locking parts (49, 49') are correspondingly engaged with the two first locking parts (43, 43') so that the inner liner 48 is contained within the recess 42 and the inner liner 48 is sleeved on the fixing seat 22.

[0095] On the other side of the connecting part 41, there are two horizontally spaced lugs (411, 412), and a rectangular hole between the two lugs (411, 412). In practice, this rectangular hole serves as a second wire hole 413, which connects to the first wire hole 26 to allow the electronic signal line to pass through. In addition, on the other side of the connecting part 41, a support part 414 extends horizontally and then bends downward. Below the top of the lower support part 414, there is an upwardly curved recessed receiving part 415 to provide space for movement. The bottom end of the lower support part 414 is mounted on a base. In practice, the bottom end of the lower support part 414 can also be inserted downward into a telescopic bracket or an adjustable support arm, or directly fixed to a desktop or device by a clamp.

[0096] One end of the upper swing member 5 has an upper latching portion 51, which has a flat plate portion 511. One end of the flat plate portion 511 has a ratchet tooth with the tip of the ratchet tooth facing downwards and the bevel of the ratchet tooth facing outwards. This ratchet tooth serves as an upper hook block 512. The upper swing member 5 has a first pivot 52 at its middle position, and the middle position of the first pivot 52 is connected to the other end of the flat plate portion 511. The other end of the upper swing member 5 has a first upper linkage portion 53 and a second upper linkage portion 54. The first upper linkage portion 53 and the second upper linkage portion 54 have the same external structure and are each a curved rod. The first upper linkage portion 53 is parallel to the second upper linkage portion 54. One end of the first pivot 52 is connected to one end of the first upper linkage 53 and is pivotally connected to a lug 411 of the connecting part 41 via a first positioning rod 55. The other end of the first pivot 52 is connected to one end of the second upper linkage 54 and is pivotally connected to another lug 412 of the connecting part 41 via a second positioning rod 56. In addition, a first stop 531 is provided on the front side of one end of the first upper linkage 53, and a second stop 541 is provided on the front side of one end of the second upper linkage 54, so that the first stop 531 and the second stop 541 simultaneously abut against the other side of the connecting part 41.

[0097] The upper part of the flat plate 511 has a pressure plate 57 and a first elastic member 58. The pressure plate 57 locks downward to the connecting part 41 of the connecting support frame 4. The first elastic member 58 includes two spaced and parallel compression springs. The upper and lower ends of the two compression springs press against the pressure plate 57 and the flat plate 511 respectively, so that the upper hook block 512 of the upper buckle 51 enters the recess 42 of the connecting part 41, and at the same time, the first stop 531 and the second stop 541 press against the connecting part 41, thereby allowing the upper buckle 51 to elastically reset.

[0098] One end of the first lower swing member 6 has a first lower latching part 61, the first lower latching part 61 has a ratchet, the tip of the ratchet is facing upward and the inclined surface of the ratchet is facing outward, the ratchet serves as a first lower hook block 62; a first arc-shaped protrusion 63 and a capsule-shaped column protrude laterally from the middle position of the first lower swing member 6, wherein the first arc-shaped protrusion 63 can move in and out of the receiving part 415, and the capsule-shaped column serves as a first lower linkage part 64; the other end of the first lower swing member 6 is pivotally connected to one side of the lower support part 414 through a second pivot 65. In implementation, the second pivot 65 may also include a cylindrical part with a pivot hole and a cylinder, wherein the cylindrical part is formed at the other end of the first lower swing member 6, and the cylinder is inserted into the pivot hole of the cylindrical part, so that the first lower swing member 6 is pivotally connected to one side of the lower support part 414. A torsion spring is sleeved on the second pivot 65, and the torsion spring serves as the second elastic element 66. The second elastic element 66 provides elastic support at the other end of the first lower swing member 6, so that the first lower hook block 62 passes upward through a limiting hole 45 to enter the recess 42, and the first lower latch 61 can be elastically reset.

[0099] The first lower swing member 6 and the second lower swing member 7 have the same external shape and structure. One end of the first lower swing member 6 is connected to one end of a connector 67, and the other end of the connector 67 is connected to one end of the second lower swing member 7, so that the first lower swing member 6 is parallel to the second lower swing member 7 and the first lower swing member 6 and the second lower swing member 7 can swing synchronously. One side of the connector 67 is provided with an upwardly protruding elongated protrusion, which serves as a third stop 68, so that the first lower swing member 6 and the second lower swing member 7 can stop simultaneously on the bottom surface of the connecting part 41. One end of the second lower swing member 7 has a second lower latching part 71, and the second lower latching part 71 has a ratchet-shaped second lower hook block 72; a second arcuate protrusion 73 and a capsule-shaped second lower connecting part 74 protrude laterally from the middle position of the second lower swing member 7. The second arcuate protrusion 73 can move in and out of the receiving part 415. The other end of the second lower swing member 7 is pivotally connected to the other side of the lower support part 414 through a third pivot 75. In implementation, the third pivot 75 may also include a cylindrical part with a pivot hole and a cylinder, wherein the cylindrical part is shaped as follows: The second lower swing member 7 is formed at the other end, and the cylinder is inserted into the pivot hole of the cylindrical part so that the first lower swing member 6 is pivotally connected to the other side of the lower support part 414; a torsion spring is sleeved on the third pivot 75, and the torsion spring acts as the third elastic member 76. The third elastic member 76 forms an elastic support at the other end of the second lower swing member 7, so that the second lower hook block 72 passes upward through another limiting hole 45' to enter the recess 42, and strengthens the rebound force so that the first lower latch part 61 and the second lower latch part 71 can be elastically reset at the same time.

[0100] The upper end of the first pressing member 8 has a flat first upper pushing part 81, and the lower end of the first pressing member 8 has a first lower pushing part 82. One side of the first lower pushing part 82 has a capsule-shaped groove. When the first lower pushing part 82 is fitted into the first lower connecting part 64, and one side of the first pushing part 82 abuts against one side of the first arc-shaped protrusion 63, the first upper pushing part 81 presses down against the first upper connecting part 53 of the upper swing member 5. The second pressing member 9 has the same external structure as the first pressing member 8. The upper end of the second pressing member 9 has a flat second upper pushing part 91, and the lower end of the second pressing member 9 has a second lower pushing part 92. One side of the second lower pushing part 92 has another capsule-shaped groove. When the second lower pushing part 92 is fitted into the second lower connecting part 74, and one side of the second pushing part 92 abuts against one side of the second arc-shaped protrusion 73, the second upper pushing part 91 presses down against the second upper connecting part 54 of the upper swing member 5.

[0101] Thus, when the first elastic member 58, the second elastic member 66, and the third elastic member 76 are in the extended state, the upper hook block 512 of the upper latching part 51 extends downward into the recessed part 42 of the connecting part 41, and the first lower hook block 62 and the second lower hook block 72 pass upward through the two limiting holes (45, 45') to simultaneously enter the recessed part 42. Figures 2-8 As shown, during assembly, by pushing the ratchet inclined surfaces of the upper hook block 512 and the first lower hook block 62 and the second lower hook block 72 respectively through one end of the fixing seat 22, the first elastic element 58, the second elastic element 66 and the third elastic element 76 can be compressed respectively, and the fixing seat 22 is directly pushed into the recessed part 42 at the top of the support frame 4. Then, through the elastic force of the first elastic element 58, the second elastic element 66 and the third elastic element 76, the upper latching part 51 is snapped downward to the upper positioning part 23 at the top of the fixing seat 22, and at the same time, the first lower latching part 61 and the second lower latching part 71 are snapped upward to the lower positioning part 24 at the bottom of the fixing seat 22, so as to securely connect the adapter 2 and the support assembly 3.

[0102] And such Figure 1 , Figure 3 , Figure 9 and Figure 10 As shown, when the user presses the first upward pushing part 81 at the upper end of the first pushing member 8 or the second upward pushing part 91 at the upper end of the second pushing member 9 to counteract the elastic force of the first elastic member 58, the second elastic member 66 and the third elastic member 76, the upper swing member 5 can swing upward, causing the upper positioning part 23 of the fixed base 22 to disengage from the restriction of the upper latching part 51. At the same time, the first lower swing member 6 and the second lower swing member 7 swing downward, causing the lower positioning part 24 of the fixed base 22 to disengage from the restriction of the first lower latching part 61 and the second lower latching part 71. As a result, the adapter 2 and the display 90 are simultaneously detached from the recessed part 42 of the support component 3, and the first elastic member 58, the second elastic member 66 and the third elastic member 76 return to their extended state.

[0103] Based on the above structure, this utility model, in addition to enabling convenient, simple, and quick assembly of the adapter connecting the display and the support assembly through the elastic force of the first, second, and / or third elastic elements, and the guiding action of the upper hook block, the first lower hook block, and / or the second lower hook block; it can also control the swing of the upper swinging member through the elastic force of the first elastic element to prevent the upper latching part from separating from the upper positioning part, and simultaneously control the swing of the first and second lower swinging members together through the elastic force of the second and / or third elastic elements to prevent the first and / or second lower latching parts from separating from the lower positioning part, thereby ensuring a stable connection between the adapter connecting the display and the support assembly. Furthermore, pressing the first and / or second pushing members can counteract the elastic force of each elastic element, causing the upper latching part to separate from the upper positioning part, and simultaneously causing the first and second lower latching parts to separate from the lower positioning part, thereby allowing the adapter and the display to be quickly detached from the support assembly simultaneously. Furthermore, depending on actual needs, the tooth heights of the first and second lower hook blocks can be the same as or different from the tooth height of the upper hook block. For example, in a preferred embodiment of this utility model, the tooth heights of the first and second lower hook blocks are respectively greater than the tooth height of the upper hook block, so that when the fixing seat is positioned in the recess, it can resist a larger rotational torque and stably support a heavier display.

[0104] While this utility model discloses preferred embodiments to achieve the above objectives, it is not intended to limit the structural features of this utility model. Those skilled in the art should understand that any easily conceived variations or modifications are possible under the technical spirit of this utility model, and are all covered by the patent application scope of this utility model.
