The lower end of the T-nut 153 is connected and fixed to the transmission wheel 151 to rotate as a whole. For example, when the T-nut connector G11 is assembled, the shaft part of the transmission wheel connecting member 152 is first arranged in the central hole of the transmission wheel 151, and the shaft part of the T-nut 153 is arranged upwards in the central hole of the bearing seat body 154. Then, at least one fixed screw SC is sequentially arranged in the through-hole H1 of the transmission wheel 151, the through-hole H2 of the transmission wheel connecting member 152, and the through-hole H3 of the T-nut 153, so as to lock the transmission wheel 151, the transmission wheel connecting member 152, and the T-nut 153 together, thereby connecting and fixing the transmission wheel 151 and the T-nut 153 together.

[0052] The bearing 155 is arranged inside the bearing seat body 154, between the T-nut 153 and the bearing seat body 154. The nut 156 is locked on the external threads on the upper end of the T-nut 153, thereby fixing the position of the bearing 155.

[0053] The C-ring clip 158, the two deep groove bearings 159, and the retainer 157 are arranged around the outer periphery of the T-nut 153. The upper and lower ends of the retainer 157 are respectively provided with one deep groove bearing 159. The position of the two deep groove bearings 159 is fixed by the retainer 157.

[0056] The upper end of the screw rod G13 is fixed to the lower connecting flange 161, and the lower end of the screw rod G13 is sequentially arranged in the nut 156, the T-shaped nut connector 153, the bearing 155, the transmission wheel connector 152, and the transmission wheel 151. A first bolt 145 and a bolt head 146 are arranged above the T-shaped nut connector G11. In one embodiment, the screw rod G13 includes an extended end 142, and the T-shaped connector E1 is arranged above the extended end 142. The extended end 142 is the upper end of the screw rod G13, which is connected and fixed to the lower end of the first bolt 145. The upper end of the first bolt 145 is a bolt head 146. The first bolt 145 is arranged in a countersink hole 161A of the lower connecting flange 161 and is locked in a threaded hole of the upper end of the screw rod G13 to fix the screw rod G13 and the lower connecting flange 161 into one body, and the bolt head 146 is fixedly connected in the countersink hole 161A of the lower connecting flange 161. Therefore, the bolt head 146 at the upper end of the first bolt 145 is used to fix the first bolt 145 to the lower connecting flange 161, and the extended end 142 of the screw rod G13 is fixed to the lower connecting flange 161 by the first bolt 145. The first bolt 145 and the bolt head 146 are integrally formed as a bolt. Other fixing members can be used instead of the first bolt 145 and the bolt head 146. The utility model adopts a first bolt 145 for fixation.

[0057] In one embodiment, as shown in Figure 3B The countersink hole 161A is arranged in the lower connecting flange 161, and the first bolt 145 is arranged in the countersink hole 161A. The countersink hole 161A is a hole processed on the surface of the material, which is characterized by a tapered hole at the hole opening for accommodating the head of the countersunk screw (such as the first bolt 145), so that the head of the first bolt 145 can be flush with or slightly lower than the surface of the lower connecting flange 161. The countersink hole 161A is mainly designed for aesthetics and functionality, such as avoiding the head of the first bolt 145 protruding, affecting the flatness or aesthetics of the lower connecting flange 161, and then the flat upper surface of the lower connecting flange 161 can be combined and fixed with the upper connecting flange 162.

[0058] Screw rod G13 is sequentially arranged on nut 156, T-shaped nut 153 and transmission wheel connecting member 152 of transmission wheel 151. The above-mentioned T-shaped nut connector G11, connecting flange G12 and screw rod G13 constitute a quick lifting module G1. Slow lifting module D1 comprises a cylinder power source D11 and a contact block D12 connected to the cylinder power source D11.

[0059] One end of T-shaped connecting member E1 is connected to upper connecting flange 162, and the other end of T-shaped connecting member E1 is provided with a fixed base 148. The upper connecting flange 162 and the fixed base 148 at both ends of the T-shaped connecting member E1 are respectively connected and fixed to the quick lifting module G1 and the slow lifting module D1, that is, one end of the T-shaped connecting member E1 is connected and fixed to the quick lifting module G1 by the upper connecting flange 162, and the other end of the T-shaped connecting member E1 is connected and fixed to the slow lifting module D1 by the fixed base 148.

[0060] One end of T-shaped connecting member E1 is provided with a fixed base 148, and the other end of T-shaped connecting member E1 is connected to an upper connecting flange 162.

The lower end of the T-shaped connecting member E1 is an upper connecting flange 162. The upper end of the T-shaped connecting member E1 is connected and fixed to the bottom of the cylinder power source D11 by the second bolt 143 and the fixed base 148. The second bolt 143 and the first bolt 145 are fixed in the same way, that is, the fixed base 148 of the T-shaped connecting member E1 is arranged in the bottom of the cylinder power source D11 by the second bolt 143 and locked in the screw hole of the fixed base 148, so as to connect and fix the cylinder power source D11 to the fixed base 148. Therefore, the bottom of the cylinder power source D11 is connected and fixed to the fixed base 148 at the upper end of the T-shaped connecting member E1 by the second bolt 143, so that the upper connecting flange 162 and the fixed base 148 at both ends of the T-shaped connecting member E1 are respectively connected and fixed to the quick lifting module G1 and the slow lifting module D1. Other fixing members can be used instead of the second bolt 143, and the second bolt 143 is used in the utility model.

[0061] When the driving transmission wheel 151 rotates to synchronously drive the transmission wheel connecting member 152 in the transmission wheel 151 and the T-shaped nut 153 connected thereto to rotate, the T-shaped nut 153 is fixed in the transmission wheel 151. When the T-shaped nut 153 rotates, the screw hole 149 at the bottom end of the screw rod G13 can be fixed to the two ends of the first supporting plate 544 by a screw member (not shown). Figures 6 to 8The bottom end of the screw G13 is fixed as a fixed end, so that the screw G13 cannot be rotated, and the T-shaped nut 153 can drive the screw G13 to move up and down linearly. The up and down linear movement (or vertical movement) of the screw G13 refers to the movement of the screw G13 in a linear direction in the vertical direction. The movement direction of the screw G13 is up and down, and the movement is in a linear direction. As shown in Figure 1 or Figure 4 The lifting position P11 is shown to drive the slow lifting module D1 and the contact block D12 connected thereto to lift the height position. The transmission wheel 151 drives the T-shaped nut 153 connected to the transmission wheel connecting piece 152 to rotate, so as to quickly drive the linear upward movement of the screw G13, that is, to convert the rotary motion into linear motion, so as to quickly reach the lifting position.

[0062] Conversely, as shown in Figure 2 or Figure 5 The reverse direction rotation of the T-shaped nut 153 connected to the transmission wheel 151 and the transmission wheel connecting piece 152 can make the extended end 142 of the screw G13 pivotally connected to the connecting flange G12 reset to the origin position P21 shown in Figure 2 or Figure 4 The slow lifting module D1 and the contact block D12 connected thereto are reset or lowered back to the height position.

[0063] The cylinder power source D11 includes a cylinder body 132, a piston 134, at least one through hole 135, at least one inlet and outlet hole 136, and a plurality of fixed rods 137. The piston 134 can move in the cylinder body 132. The piston 134 includes a protruding end 134A and a top 134B. The protruding end 134A is connected to the top 134B. The top 134B is connected to the bottom of the contact block D12, so that the cylinder power source D11 slowly lifts the corresponding contact block D12 to adjust the height of the contact block D12. One end of the fixed rod 137 is provided in the cylinder body 132, and the other end of the fixed rod 137 is connected to the top 134B, so that the piston 134 can uniformly balance on the plurality of fixed rods 137 to lift the contact block D12 up and down slowly, and the fixed rod 137 can move together with the contact block D12.

[0064] In an embodiment, the cylinder body 132 is fixed to the bottom of the cylinder body 132 by a bolt (not shown) passing through the through hole 135. At least one inlet and outlet hole 136 is provided on the cylinder body 132.

[0065] The aforementioned cylinder power source D11, the contact block D12 and the T-shaped connecting piece E1 constitute a slow lifting module D1. By using the controllability of the air pressure of the cylinder power source D11, the cylinder power source D11 drives the contact block D12 to move, the piston 134 can move in the cylinder body 132, so that the convex end 134A of the piston 134 and the top 134B connected thereto can drive the contact block D12 to slide on the fixed rod 137 to change the height position thereof to lift to the lifting position P12 as shown in Figure 1 or Figure 4 The convex end 134A of the piston 134 can drive the contact block D12 to change the height position thereof to reset or lower to the original position P22 as shown in Figure 2 or Figure 5

[0066] In an embodiment, the lifting mechanism 100 comprises a gasket 111 arranged on the contact block D12. The contact block D12 uses a bolt (not shown) to pass through a through hole 111A to fix the gasket 111 on the contact block D12.

[0067] Therefore, the lifting mechanism 100 can comprise two independent lifting modes, which are a fast lifting module G1 and a slow lifting module D1. The function of the slow lifting module D1 of the utility model is to make up for the fast lifting module G1, and can compensate for the gap generated by the combination of parts or the tolerance generated by the measuring tool. Since the cylinder output can be according to the weight of the object to be lifted, and by using the air pressure regulation control and the limited position function of the cylinder, the object to be lifted can be lifted with the most appropriate force, so that the object to be lifted is completely attached to the surface of another object.

[0068] Figure 6 It is a perspective view of an embodiment of the lifting device of the raised floor according to the utility model. Figure 7 It is a schematic view of an embodiment of the lifting device of the raised floor according to the utility model at a lifting position. Figure 8 It is a schematic view of an embodiment of the lifting device of the raised floor according to the utility model at an original position. Please refer to Figures 6 to 8 wherein Figures 6 to 8 The fast lifting modules G1, G2, G3 and G4 and the slow lifting modules D1, D2, D3 and D4 are the same as Figures 1 to 5 The mechanism of the fast lifting module G1 and the slow lifting module D1 is the same.

[0069] Figure 1 , Figure 4 The lifting position P1 of the lifting mechanism 100 can correspond to the lifting position P1 of the lifting mechanism 100 in Figure 7 The lifting position P1 of the lifting mechanism 100 can correspond to the lifting position P1 of the lifting mechanism 100 in Figure 7 ​The lifting position P1 of the lifting mechanism 100 in the high-floor lifting device 50 includes the lifting position P11 of the fast lifting module G1, G2, G3, G4 and the lifting position P12 of the slow lifting module D1, D2, D3, D4. Figure 2 、 Figure 5 The origin position P2 of the high-floor lifting device 50 can correspond to Figure 8 The lifting mechanism 100 in the high-floor lifting device 50 includes the origin position P21 of the fast lifting module G1, G2, G3, G4 and the origin position P22 of the slow lifting module D1, D2, D3, D4.

[0070] The lifting device 54 of the high floor is used to lift the high floor 40. The lifting device 54 of the high floor includes four lifting mechanisms 100, and a driving motor GM. The lifting mechanism 100 is used to carry and lift the high floor 40, and the driving motor GM is used to drive the four lifting mechanisms 100 to move along the lifting direction LB, so as to move the high floor 40 along the lifting direction LB.

[0071] It should be noted that the high floor 40 of the utility model is in the shape of a rectangular body, and the size of the high floor 40 of the utility model is, for example, 600mm*600mm*60mm, and is made of materials such as aluminum alloy die casting.

[0072] Since the four lifting mechanisms 100 are supported at the four corners of the high floor 40, they can be stably lifted. In other embodiments, the four lifting mechanisms 100 can each have a driving mechanism, and by setting the torque, the four lifting mechanisms 100 can be simultaneously lifted to the predetermined position.

[0073] In an embodiment, the lifting device 54 of the high floor of the utility model includes four lifting mechanisms 100, a driving motor GM, a belt 542, and two first support plates 544 and two second support plates 545. The two ends of the two first support plates 544 are respectively connected to the two second support plates 545, and a quadrangular frame is formed by connecting the two first support plates 544 and the two second support plates 545, and the four lifting mechanisms 100 are synchronously lifted and lowered in a straight line to make the screw G13 in the four lifting mechanisms 100 synchronously drive the contact block D12 of the lifting device 54 of the high floor to synchronously contact the four corners of the high floor.

[0074] The driving motor GM is fixed between two lifting mechanisms 100. The belt 542 is wound around the driving wheels 151 of the four lifting mechanisms 100 and the driving motor GM to form a synchronous driving mechanism. In this way, the driving motor GM can drive the belt 542 to rotate, and the belt 542 can drive the driving wheels 151 of each lifting mechanism 100 to make the contact blocks D12 of each lifting mechanism 100 perform lifting and lowering actions. Since the four lifting mechanisms 100 are driven by the same driving source (the driving motor GM) and the transmission structure (the belt 542) to perform lifting and lowering actions synchronously, the contact blocks D12 can be lifted or lowered to a predetermined position, so that the difference in the lifting actions of the four lifting mechanisms 100 can be avoided.

[0075] In an embodiment, the lifting mechanism 100 can include two independent lifting modes, i.e., a fast lifting module G1, G2, G3, G4 and a slow lifting module D1, D2, D3, D4. In addition to synchronously performing the lifting and lowering actions of the four lifting mechanisms 100, the fast lifting module G1, G2, G3, G4 can synchronously and quickly lift the heights of the four lifting mechanisms 100. In addition, the slow lifting module D1, D2, D3, D4 can be used to supplement the fast lifting module G1, G2, G3, G4 to enhance the fit of the four corners of the raised floor to be fitted.

[0076] Please continue to refer to Figure 6 and Figure 7 As shown in the drawings, the fast lifting module G1 of each lifting mechanism 100 is connected to the slow lifting module D1, D2, D3, D4. The fast lifting module G1 includes a T-shaped nut connector G11, a connecting flange G12, and a screw rod G13. One end of each of the four screw rods G13 is fixed to the two ends of the first support plate 544. The belt 542 drives the driving wheel 151 to rotate to synchronously drive the driving wheel connecting piece 152 and the T-shaped nut 153 (as shown in the drawings) connected thereto to rotate. At this time, since the first support plate 544 and the second support plate 545 at the bottom of the four screw rods G13 are fixed ends, the screw rod G13 cannot be rotated, the driving wheel 151 synchronously drives the T-shaped nut 153 connected to the driving wheel connecting piece 152 to rotate, and the T-shaped nut 153 drives the screw rod G13 to move up and down linearly, as shown in the drawings. Figure 4 Figure 6 ​The lifting position P11 is shown to drive the slow lifting module D1, D2, D3, D4 and the contact block D12 connected thereto to lift the height position, thereby lifting the height position of the elevated floor 40. The transmission wheel 151 synchronously drives the T-shaped nut 153 connected to the transmission wheel connecting member 152 to rotate, and the T-shaped nut 153 drives the screw rod G13 to move linearly upward, and the linear upward movement of the screw rod G13 is driven quickly, that is, the rotational movement of the T-shaped nut 153 is converted into the linear movement of the screw rod G13, so as to quickly reach the lifting position. The foregoing single power source (drive motor GM) simultaneously drives the four lifting mechanisms 100, and the synchronous and rapid lifting lifts the elevated floor 40 to the predetermined height, and can avoid the position difference caused by the different lifting positions of the four lifting mechanisms 100, thereby ensuring that the four corners of the elevated floor 40 can be stably lifted by the four lifting mechanisms 100, avoiding the height difference of the four corners of the elevated floor 40, and avoiding the phenomenon of the elevated floor 40 falling during lifting.

[0077] Conversely, as shown in Figure 7 The transmission wheel 151 synchronously drives the T-shaped nut 153 connected to the transmission wheel connecting member 152 to rotate in the opposite direction, so that the extension end 142 of the screw rod G13 and the connecting flange G12 connected thereto are reset to the original position P21 as shown. Figure 7 The slow lifting module D1, D2, D3, D4 and the contact block D12 connected thereto are reset to the height position.

[0078] In addition to the foregoing rapid lifting module G1, G2, G3, G4, the slow lifting module D1, D2, D3, D4 of the utility model comprises a cylinder power source D11, a contact block D12, and a T-shaped connecting member E1. The two ends of the T-shaped connecting member E1 are respectively connected and fixed to the upper connecting flange 162 and the cylinder power source D11, that is, connected to the rapid lifting module G1 by the T-shaped connecting member E1. The cylinder power source D11 is connected to the contact block D12, the gasket 111 is fixed to the contact block D12, and the other end of the cylinder power source D11 is connected to the rapid lifting module G1, G2, G3, G4. The function of the slow lifting module D1, D2, D3, D4 of the utility model is to compensate for the rapid lifting module G1, G2, G3, G4, the gap between the components, the thickness tolerance of the four corners of the elevated floor 40 during processing, and the total error caused by various factors including but not limited to measuring tools, so that the surface of the four corners of the elevated floor 40 cannot be completely attached to the attached object. The controllability of the air pressure of the cylinder power source D11 is used to drive the contact block D12 to move, so as to adjust the height position of the elevated floor 40.

[0079] Due to the cylinder output can be in accordance with the weight of the elevated floor 40, and using air pressure regulating control, and the limited infinite position function of the cylinder, the elevated floor 40 can be lifted to the most appropriate force, so that the four corners of the elevated floor 40 surface completely fit to the position of the fitting object, thereby achieving the effectiveness and accuracy of the flatness measurement value.

[0080] In summary, the lifting mechanism of the utility model has two independent fast lifting modules and slow lifting modules, which can quickly lift the predetermined height by the fast lifting module, and can also compensate for the fitting error by the air pressure regulation of the slow lifting module.

[0081] Furthermore, the utility model discloses a lifting device of an elevated floor, which is provided with four lifting mechanisms to form a synchronous driving mechanism to perform synchronous lifting action, so that the elevated floor can be lifted or lowered to a predetermined position, thereby avoiding the position difference of the four lifting mechanisms.

[0082] Although some embodiments of the utility model have been disclosed as above by the embodiments, they are not used to limit the utility model, and any person skilled in the art with ordinary knowledge can make some changes and decorations without departing from the spirit and scope of the utility model, which belongs to the protection scope of the utility model.
