For the convenience of subsequent description, the quick-release support device 100 is defined as a front-to-back direction X, a left-to-right direction Y perpendicular to the front-to-back direction X, and an up-down direction Z perpendicular to the front-to-back direction X and the left-to-right direction Y. The front-to-back direction X in FIG1 is the direction indicated by the arrow as the front, and the opposite direction is the rear. The left-to-right direction Y in FIG1 is the direction indicated by the arrow as the left, and the opposite direction is the right. The up-down direction Z in FIG1 is the direction indicated by the arrow as the top, and the opposite direction is the bottom.

Referring to Fig. 2, Fig. 3 and Fig. 4, the support mechanism 1 includes a support frame 11 and a bracket 12 disposed on the support frame 11. The bracket 12 has at least one stop surface 124, and the stop surface 124 is spaced apart from the support frame 11 along the front-rear direction X. The sliding frame 2 is slidably connected to the bracket 12 along the front-rear direction X. The sliding frame 2 includes at least one clamping surface 224 facing the stop surface 124, and a back surface 212 opposite to the clamping surface 224 and facing the support frame 11. The hanging bracket 3 is hung on the bracket 12 and is located between the stop surface 124 and the clamping surface 224, and the hanging bracket 3 is used to be assembled to the display (not shown). The actuator 4 can be movably connected to the support frame 11 and can be operated to push the back side 212 of the sliding frame 2 forward, so that the pressing surface 224 presses the hanger 3 against the stop surface 124 and clamps the hanger 3 together with the stop surface 124.

The specific structure, assembly and disassembly methods of the quick-release support device 100 are described in detail below:

Referring to Fig. 2, Fig. 3 and Fig. 4, the support mechanism 1 can be a wall mount fixed on a wall, or a stand supported on a plane. The support frame 11 of the support mechanism 1 in the figure is an incomplete schematic structure, and only part of the structural features of the support frame 11 are shown in the figure. It can be understood that when the support mechanism 1 is the wall mount, the support frame 11 will also have a structure for locking on the wall, and when the support mechanism 1 is the stand, the support frame 11 will also have a structure for standing on the plane.

The support frame 11 includes a frame body 111 and a shaft 112 disposed on the frame body 111. The frame body 111 has a vertical plate 113 and two protrusions 114. The vertical plate 113 has a front face 115 facing forward and a back face 116 opposite to the front face 115. The vertical plate 113 is formed with a through hole 117 extending between the front face 115 and the back face 116, and a plurality of first screw holes 118 extending between the front face 115 and the back face 116 and spaced apart. The number of the first screw holes 118 is three for example but is not limited thereto. The protrusions 114 are protruding from the back face 116 of the vertical plate 113 and are spaced apart along the left-right direction Y and are respectively located on the left and right sides of the through hole 117. Each of the protrusions 114 is formed with an axial hole 119. The shaft 112 is inserted through the axial holes 119 of the protrusions 114. The axial direction of the shaft 112 extends along the left-right direction Y.

The bracket 12 includes a plurality of spaced supporting members 121. Each of the supporting members 121 has a supporting guide column 122 fixedly connected to the support frame 11, and a stop head 123 formed at the front end of the supporting guide column 122. The supporting guide column 122 is used for hanging the hanger 3. The stop head 123 is used to stop the hanger 3. In this first embodiment, each of the supporting members 121 is exemplified by a screw. The supporting guide column 122 is a cylindrical stud, which is screwed to the corresponding first screw hole 118 of the support frame 11. The stop head 123 is a cylindrical screw head. The outer diameter of the stop head 123 is larger than the outer diameter of the supporting guide column 122. The stop head 123 has a ring-shaped stop surface 124 connected to the supporting guide post 122, and a rear conical surface 125 extending radially outward and forward from the outer edge of the stop surface 124. The rear conical surface 125 is used for the hanger 3 to contact and guide the hanger 3 to move downward toward the corresponding supporting guide post 122.

The sliding frame 2 includes a vertical plate 21, and a plurality of spaced clamping members 22 disposed on the vertical plate 21. The vertical plate 21 has a front face 211 facing forward, and a back face 212 opposite to the front face 211 and facing the front face 115 of the support frame 11. The vertical plate 21 is formed with a plurality of spaced second screw holes 213 extending between the front face 211 and the back face 212. The number of the second screw holes 213 is the same as the number of the first screw holes 118, and the second screw holes 213 are respectively located in front of the first screw holes 118.

Each of the clamping members 22 can be slidably mounted on the corresponding supporting guide column 122 of the supporting member 121. Each of the clamping members 22 has a sleeve 221 fixedly connected to the vertical plate 21 and slidably mounted on the corresponding supporting guide column 122, and a clamping head 222 formed at the front end of the sleeve 221 and slidably mounted on the corresponding supporting guide column 122. The clamping head 222 is used to clamp the rack 3 to the corresponding stop head 123. In the first embodiment, each of the clamping members 22 is exemplified by a hollow screw. The sleeve 221 is a hollow stud in a cylindrical shape, which is screwed to the corresponding second screw hole 213 of the vertical plate 21. The clamping head 222 is a hollow screw head in a cylindrical shape. The outer diameter of the clamping head 222 is larger than the outer diameter of the sliding sleeve 221. The sliding sleeve 221 and the clamping head 222 jointly define a sliding hole 223 for the corresponding supporting guide column 122 to pass through. The clamping head 222 has a clamping surface 224 that is annular and surrounds the sliding hole 223 and faces the corresponding stop surface 124 of the stop head 123, and a front conical surface 225 that extends radially outward and backward from the outer edge of the clamping surface 224. The front conical surface 225 is used for the hanger 3 to contact to guide the hanger 3 to move downward toward the corresponding supporting guide column 122.

The hanger 3 includes a front side 31 facing forward, and a back side 32 opposite to the front side 31. The hanger 3 is formed with a plurality of buckle holes 33 extending between the front side 31 and the back side 32 and spaced apart from each other. Each of the buckle holes 33 is used to buckle with the corresponding supporting guide column 122 of the supporting member 121. In the first embodiment, each of the buckle holes 33 has a circular perforated portion 331, and a long buckle hole portion 332 connected to the top end of the perforated portion 331. The width of the perforated portion 331 along the left-right direction Y is greater than the width of the buckle hole portion 332 along the left-right direction Y. The perforated portion 331 is larger than the corresponding stop head 123 of the supporting member 121, and is used for the corresponding stop head 123 to pass through so that the buckle hole portion 332 moves to the top of the corresponding supporting guide column 122 or moves away from the top of the corresponding supporting guide column 122. The length of the buckle hole portion 332 extends along the up-down direction Z. The buckle hole portion 332 is used to buckle with the corresponding supporting guide column 122. It should be noted that the bracket 3 in the figure is an incomplete schematic structure, and only part of the structural features of the bracket 3 are shown in the figure. It can be understood that the bracket 3 will also have a structure for assembling and fixing to the display, and the bracket 3 and the display can be fixedly combined together by screw locking or a buckle method in which a hook and a slot cooperate.

The actuator 4 is inserted through the through hole 117 of the support frame 11 and can move between an unlocked position (as shown in FIG. 4 ) and a locked position (as shown in FIG. 5 ). In the unlocked position, the actuator 4 does not abut against the back surface 212 of the sliding frame 2 and allows the sliding frame 2 to slide along the front-rear direction X. In the locked position, the actuator 4 abuts against the back surface 212 so that each of the pressing surfaces 224 of the sliding frame 2 and the corresponding stop surface 124 jointly clamp the hanging frame 3.

In the first embodiment, the actuator 4 is a wrench pivoted to the shaft 112 of the support frame 11 and capable of rotating between the unlocking position and the locking position. The actuator 4 includes a cam 41 pivoted to the shaft 112 and inserted into the through hole 117, and a lever 42 extending rearward from the cam 41. The cam 41 is formed with a pivot hole 411 pivoted to the shaft 112. The cam 41 has a release surface 412, a top abutment surface 413, and a push surface 414 connected between the release surface 412 and the top abutment surface 413. The distance between the abutting surface 413 and the axis of the shaft 112 is greater than the distance between the releasing surface 412 and the axis of the shaft 112. The pushing surface 414 gradually moves away from the shaft 112 from the releasing surface 412 toward the abutting surface 413. The pushing surface 414 is used to push the back surface 212 of the sliding frame 2 to move it forward. In the unlocking position, the releasing surface 412 corresponds to the back surface 212 of the sliding frame 2 and does not abut the back surface 212. In the locking position, the abutting surface 413 abuts against the back surface 212.

When the display is to be assembled and fixed to the support mechanism 1 through the bracket 3, first, the actuator 4 is rotated to the unlocking position so that the release surface 412 of the cam 41 corresponds to the back surface 212 of the sliding frame 2, so as to allow the sliding frame 2 to slide along the front-back direction X. Then, the sliding frame 2 is pushed backward so that each of the pressing members 22 slides backward along the corresponding supporting guide column 122 of the supporting member 121. When the back surface 212 of the vertical plate 21 contacts the release surface 412 of the cam 41 and is blocked by the release surface 412, the sliding frame 2 cannot continue to slide backward. Thereby, the clamping surface 224 of each clamping member 22 can maintain an appropriate distance from the corresponding stop surface 124 of the supporting member 121, so that the rack 3 can be accommodated between the clamping surfaces 224 and the stop surfaces 124 during subsequent assembly.

Next, align the perforated portion 331 of each buckle hole 33 of the hanger 3 with the front of the stopper 123 of the corresponding support member 121 of the bracket 12. Then, move the hanger 3 backward for a distance, and each stopper 123 of the support member 121 will pass through the perforated portion 331 of the corresponding buckle hole 33, so that the buckle hole portion 332 of each buckle hole 33 moves to the top of the corresponding support guide column 122. Release the hanger 3 to allow it to move downward by gravity. When the hanger 3 has a slight forward position deviation in the front-rear direction X so that the hanger 3 contacts the rear conical surface 125 of the stop head 123 of the corresponding supporting member 121 during the downward movement, the hanger 3 will move downward along the rear conical surface 125 and be gradually corrected by the rear conical surface 125, so that the button hole portion 332 of each button hole 33 can be smoothly aligned with the corresponding supporting guide column 122 and snapped onto the supporting guide column 122. When the hanger 3 has a slight backward position deviation in the front-rear direction X so that the hanger 3 contacts the front conical surface 225 of the corresponding clamping head 222 of the clamping member 22 during the downward movement, the hanger 3 moves downward along the front conical surface 225 and is gradually corrected by the front conical surface 225, so that the button hole portion 332 of each button hole 33 can be smoothly aligned with the corresponding supporting guide column 122 and snapped onto the supporting guide column 122. Thus, the rear conical surface 125 and the front conical surface 225 play a role in correcting the hanger 3 to eliminate the position deviation of the hanger 3 in the front-rear direction X, thereby ensuring that the buckle hole portion 332 of each buckle hole 33 can be smoothly buckled on the corresponding supporting guide post 122. At this time, the hanger 3 is hung on the supporting guide posts 122 of the supporting members 121 and is temporarily positioned on the supporting guide posts 122.

Referring to FIG. 4 and FIG. 5 , the lever 42 of the actuator 4 is then rotated in a first rotation direction R1, so that the lever 42 drives the cam 41 to rotate. Since the push surface 414 of the cam 41 gradually moves away from the shaft rod 112 from the release surface 412 toward the abutment surface 413, during the rotation of the cam 41, the push surface 414 applies a push force to the back surface 212 of the slide frame 2 to push the back surface 212 forward, so that the vertical plate 21 drives the clamping members 22 to slide forward. When the clamping surface 224 of each clamping member 22 contacts the back surface 32 of the rack 3, the clamping surface 224 applies a thrust to the back surface 32 to push the back surface 32 forward, so that the rack 3 moves forward toward the stop heads 123 of the supporting members 121.

When the front face 31 of the rack 3 contacts the stop faces 124 of the stop heads 123, the rack 3 is stopped by the stop faces 124 and cannot continue to move forward. At this time, the thrust force applied by the clamping surface 224 of each clamping member 22 to the back face 32 of the rack 3 causes the front face 31 to be pressed against the stop faces 124, so that the clamping surface 224 of each clamping member 22 and the corresponding stop face 124 of the supporting member 121 jointly clamp the rack 3.

When the actuator 4 rotates to the locking position, the abutting surface 413 of the cam 41 abuts against the back surface 212 to lock the sliding frame 2 and prevent the sliding frame 2 from sliding backward, so that the pressing surface 224 of each pressing member 22 and the corresponding stopping surface 124 of the supporting member 121 can be maintained in a clamping state of stably clamping the bracket 3. In this way, the display is stably assembled and fixed to the supporting mechanism 1 through the bracket 3.

When the display is to be removed from the supporting mechanism 1 through the bracket 3, the lever 42 of the actuator 4 is rotated in a second rotation direction R2 opposite to the first rotation direction R1, so that the top contact surface 413 of the cam 41 is away from the back surface 212, thereby releasing the state of locking the sliding frame 2. When the actuator 4 returns to the unlocking position, the release surface 412 corresponds to the back surface 212 of the sliding frame 2, so that the sliding frame 2 can be pushed backward, so that the pressing surface 224 of each pressing member 22 is separated from the back surface 32 of the bracket 3. Then, the bracket 3 is lifted up by an appropriate distance, so that the button hole portion 332 of each button hole 33 moves away from the corresponding supporting guide column 122. Then, the bracket 3 is moved forward for a distance, and the stopper 123 of each supporting member 121 passes through the perforated portion 331 of the corresponding button hole 33, so that the button hole portion 332 of each button hole 33 moves away from the corresponding supporting guide column 122. In this way, the monitor is removed from the supporting mechanism 1 through the bracket 3.

By means of the quick-release support device 100, the display can be conveniently and quickly assembled and fixed to the support mechanism 1 or disassembled from the support mechanism 1 through the bracket 3 without using screws and auxiliary tools, thereby greatly improving the convenience of assembly and disassembly and saving assembly and disassembly man-hours.

6 and 7 , the second embodiment of the quick-release support device 100 of the present invention has an overall structure that is substantially the same as that of the first embodiment, except for the actuator 4 .

In the second embodiment, the through hole 117 of the vertical plate 113 of the support frame 11 is a screw hole. The actuator 4 is a screw that is screwed to the through hole 117 and can move between the unlocking position and the locking position. The actuator 4 includes a stud 43 that is screwed to the through hole 117, and a screw head 44 that is formed at the rear end of the stud 43 and is spaced from the back side 116 of the vertical plate 113. The stud 43 is used to push and abut against the back side 212 of the sliding frame 2. When the actuator 4 is in the unlocking position (as shown in FIG. 7 ), the stud 43 does not abut against the back side 212 of the sliding frame 2, and the screw head 44 is away from the back side 116 of the vertical plate 113.

Referring to FIG. 7 and FIG. 8 , when the slide frame 2 is to be locked by the actuator 4, the screw head 44 is rotated clockwise to drive the stud 43 to rotate and move forward along the front-rear direction X. During the forward movement of the stud 43, a thrust force is applied to the back surface 212 of the slide frame 2 to push the back surface 212 forward, so that the vertical plate 21 drives the clamping members 22 to slide forward. In this way, the clamping surfaces 224 of the clamping members 22 clamp the hanger 3 against the stop surfaces 124 and clamp the hanger 3 together with the stop surfaces 124. When the actuator 4 moves to the locking position (as shown in FIG. 8 ), the stud 43 presses against the back surface 212 to lock the sliding frame 2 and prevent the sliding frame 2 from sliding backward, so that the clamping surface 224 of each clamping member 22 and the corresponding stopping surface 124 of the supporting member 121 can remain in the clamping state of stably clamping the hanger 3.

To release the state of the actuator 4 locking the slide frame 2, the screw head 44 is rotated counterclockwise to drive the stud 43 to rotate and move backward along the front-rear direction X. When the actuator 4 returns to the unlocking position, the stud 43 does not abut against the back side 212 of the slide frame 2 and the state of locking the slide frame 2 is released.

It should be noted that the quick-release support device 100 of each embodiment may also have the following different implementation modes according to the needs:

One implementation is that the supporting guide column 122 of each supporting member 121 is fixed to the vertical plate 113 by welding, and the sliding sleeve 221 of each clamping member 22 is fixed to the vertical plate 21 by welding.

Another implementation is that the number of the first screw hole 118, the supporting member 121, the second screw hole 213, the clamping member 22, and the buckle hole 33 is one each.

In summary, in the quick-release support device 100 of each embodiment, the display can be conveniently and quickly assembled and fixed to the support mechanism 1 or disassembled from the support mechanism 1 without using screws and auxiliary tools during the assembly and disassembly process through the bracket 3, thereby greatly improving the convenience of assembly and disassembly and saving disassembly time, so the purpose of the present invention can be achieved.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the patent of the present invention.
