DETAILED DESCRIPTION

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] This embodiment provides a mounting mechanism, which can be used for both seat mounting and canopy hoisting. In this embodiment, hoisting is used as an example for description. Figure 1 As shown, the mounting mechanism includes a first part 1 and a second part 2. The first part 1 includes a connecting member 11 and a limiting assembly 12, and the connecting member 11 is used to mount the first part 1 on a shelf. Figure 2 As shown, the limiting assembly 12 includes a limiting shell 121, two grab arms 122 and a first return member 123, and the limiting shell 121 is connected to the connecting member 11. The limiting shell 121 is hollow inside, and an opening is provided at one end of the limiting shell 121 away from the connecting member 11. The two grab arms 122 are both hinged in the limiting shell 121. When the two grab arms 122 rotate away from each other and open, the first return member 123 generates elastic deformation, and the elastic force generated by the elastic deformation of the first return member 123 can drive the two grab arms 122 to rotate toward each other and reset. The two grab arms 122 are both provided with a clamping portion 1221 at one end relatively close to the outside of the limiting shell 121. The second part 2 includes a head 21 and a connecting portion 22 extending from the head. The outer diameter of the connecting portion 22 is smaller than the outer diameter of the head 21, so that a step is formed at the junction of the head 21 and the connecting portion 22. The second part 2 is installed on the object to be hoisted through the connecting portion 22. In this embodiment, the first return member 123 is a compression spring, and opposite ends of the compression spring are respectively connected to the two grasping arms 122 .

[0030] In other embodiments, the first return member 123 may also be a tension spring, and two tension springs are provided, one tension spring being provided between a gripping arm 122 and the limiting shell 121. In this embodiment, the object to be hoisted is an LED display screen, and in other embodiments, the object to be hoisted may also be any other object.

[0031] When the mounting mechanism is used, Figure 3 As shown, the first part 1 is first installed on the rack through the connecting piece 11, and the second part 2 is installed on the LED display screen that needs to be hoisted; when installing the LED display screen that needs to be hoisted, move the LED display screen that needs to be hoisted, and operate to make the head 21 of the second part 2 move from the opening of the limit shell 121 through the two clamping parts 1221 toward the inside of the limit shell 121, and combine with Figure 4As shown, the head 21 of the second part 2 pushes the two clamping parts 1221 to open so that the head 21 of the second part 2 can penetrate, and the first return member 123 produces elastic deformation. When the head 21 of the second part 2 passes through the clamping part 1221, the elastic force of the first spring 123 drives the two clamping parts 1221 to rotate toward each other and reset to clamp the head 21. Figure 5 As shown, the clamping parts 1221 of the two gripping arms 122 are clamped on both sides of the connecting part 22 of the second part 2. Since the outer diameter of the head 21 is larger than the outer diameter of the connecting part 22, the second part 2 is clamped and cannot be separated. Figure 2 As shown, an auxiliary inclined surface 12211 is provided at one end of the clamping portion 1221 relatively close to the outside of the limiting shell 121, and an auxiliary slope 211 is provided at one end of the head 21 relatively far from the connecting portion 22. With the help of the auxiliary inclined surface 12211 and the auxiliary slope 211, the head 21 can push the two grasping arms 122 to rotate away from each other and open.

[0032] In this embodiment, if Figure 2 As shown, the limiting assembly 12 also includes a limiting slider 124, a limiting column 125 and a second return member 126. The limiting slider 124 is located between the two gripping arms 122 and is linked to the two gripping arms 122. The limiting column 125 is slidably inserted in the limiting slider 124. When the limiting column 125 moves toward the limiting slider 124, the second return member 126 generates elastic deformation. In this embodiment, there are two limiting columns 125, and the two limiting columns 125 are symmetrically slidably inserted in the limiting slider 124. The second return member 126 is a compression spring and is located between the two limiting columns 125. Correspondingly, the limiting shell 121 is provided with two limiting holes 1211. In this embodiment, the limiting column 125 is provided with an inclined surface 1251, and the inclined surface 1251 facilitates the limiting column 125 to move toward the limiting slider 124. In this embodiment, reset handles 1252 are provided on the front and rear sides of the two limit columns 125, and avoidance grooves 1212 are provided at the positions corresponding to the limit shell 121 and the reset handles 1252. The reset handles 1252 pass through the limit slider 124 and then pass through the avoidance grooves 1212 to be exposed outside the limit shell 121. The reset handles 1252 can move horizontally and vertically in the avoidance grooves 1212 and the limit slider 124.

[0033] In this embodiment, two connecting plates 127 are respectively provided between the limit slider 124 and the two gripping arms 122. One end of the connecting plate 127 is hinged to the limit slider 124, and the other end is hinged to the gripping arm 122. Figure 3 and Figure 5As shown, in the initial state and the hoisting use state, one end of the two connecting plates 127 on the same side that are hinged to the limit slider 124 is arched upward to facilitate the linkage between the connecting plates 127, the limit slider 124 and the grab arm 122. In this embodiment, the limit slider 124 is provided with a guide column 1241, and the limit shell 121 is provided with a guide hole 1213. The guide column 1241 is inserted into the guide hole 1213. When the limit slider 124 moves, the guide column 1241 moves along the guide hole 1213, and the guide hole 1213 plays a guiding and limiting role. In this embodiment, one end of the four connecting plates 127 is respectively pivoted to the guide column 1241 on the same side. In this embodiment, the limiting shell 121 includes a first section 1214 close to the opening and a second section 1215 away from the opening. Two limiting holes 1211 are respectively opened on opposite sides of the second section 1215. In the connecting direction of the two limiting holes 1211, the spacing between the inner sides of the second section 1215 is smaller than the spacing between the inner sides of the first section 1214. The two grab arms 122 are hinged in the first section 1214. The initial positions of the limiting slider 124, the limiting column 125 and the second spring 126 are in the first section 1214.

[0034] When disassembly is required after installation, Figure 6 As shown, the LED display screen that is hoisted is pushed, and the operation causes the second part 2 to continue to move into the limiting shell 121. The head 21 of the second part 2 will abut against the limiting slider 124, pushing the limiting slider 124 to move toward the second section 1215 of the limiting shell 121. When the limiting slider 124 moves, the two clamping parts 1221 are driven to rotate away from each other and open through the connecting plate 127. The first return member 123 generates elastic deformation. After the limiting slider 124 enters the second section 1215, the inner wall of the second section 1215 pushes the limiting column 125 to move into the limiting slider 124. The second return member 126 generates elastic deformation. Figure 7 As shown, when the limiting slider 124 moves to the point where the limiting column 125 is aligned with the limiting hole 1211, the elastic force of the second spring 126 drives the limiting column 125 to move and insert into the limiting hole 1211. At this time, the two clamping portions 1221 are opened to a distance greater than the outer diameter of the head 21 of the second part 2, and the second part 2 can be taken out from the limiting shell 121. Figure 8 As shown, the suspended LED display screen can be disassembled; after disassembly, the two limit columns 125 are driven to move toward each other and disengage from the limit holes 1211 by means of the reset handle 1252, and the elastic force of the first return member 123 drives the two grasping arms 122 to rotate toward each other and reset, and drives the limit slider 124 to move toward the first section 1214 and reset, and the entire limit assembly 12 is reset to facilitate the next installation and use.

[0035] like Figure 2As shown, in this embodiment, in order to avoid mutual interference between the first return member 123 and the limit slider 124, a clearance groove 1242 is provided below the limit slider 124, and the first return member 123 can be located at the clearance groove 1242. The first return member 123 and the second part 2 are staggered front and back in space, and the first return member 123 will not affect the up and down movement of the second part 2. The reset handle 1252 and the connecting plate 127 are also staggered and will not interfere with each other.

[0036] In this embodiment, if Figure 2 As shown, the connector 11 includes a first section 111, a second section 112 and a locking section 113. One end of the locking section 113 is hinged to one end of the first section 111, and the other end of the first section 111 is hinged to one end of the second section 112. The other end of the second section 112 is provided with a bayonet 1121. The locking section 113 can be inserted into and removed from the bayonet 1121. The locking section 113 is threadedly connected with a nut 3. After the locking section 113 is inserted into the bayonet 1121, the nut 3 is tightened to achieve locking. The first section 111 and the second section 2 rotate relative to each other, and the position of the nut 3 is adjusted, so as to match the diameters of different brackets. In this embodiment, in order to correspond to the round tube of the bracket, the first section 111 and the second section 112 are both arc-shaped. In other embodiments, when the bracket is a square tube, the first section 111 and the second section 112 can be square in shape. In this embodiment, the first sub-portion 111 and the limiting shell 121 are assembled together by screws 4 .

[0037] The installation mechanism in this embodiment, when used for the ceiling hoisting of the LED display screen, only one person is needed to achieve quick installation, eliminating the trouble of multiple people operating, and is also very convenient when disassembling, making both installation and disassembly more convenient.

[0038] The above specific embodiments are merely explanations of the present invention, and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the above embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
