However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0034] The utility model discloses a synchronous belt mechanism and a lifting column using the same, wherein a fixing piece is clamped on the tooth surface of the synchronous belt through a tooth groove, so that the extension direction of a support rod is parallel to the extension direction of the synchronous belt, and the end of the support rod is connected to the lifting column, so that the load force is parallel to the action direction of the synchronous belt, thereby solving the problem of low load of the synchronous belt mechanism in the prior art.

[0036] The two synchronous wheels 200 are installed on the fixing bracket 100 , the synchronous belt 300 is arranged around the synchronous wheels 200 , the fixing member 400 and the gasket 500 are connected and installed on the synchronous belt 300 , and the support rod 600 is connected to the fixing member 400 .

[0037] The fixing member 400 is provided with a tooth groove 401 , and the tooth groove 401 is clamped on the tooth surface of the synchronous belt 300 . The fixing member 400 and the gasket 500 are arranged on both sides of the synchronous belt 300 and apply a clamping force to the synchronous belt 300 .

[0038] The support rod 600 extends along the direction of the synchronous belt 300, so that the extension direction of the support rod 600 is parallel to the extension direction of the synchronous belt 300. The end of the support rod 600 away from the fixing member 400 is connected to the lifting column, so that the lifting column applies a force to the synchronous belt 300 along the extension direction of the support rod 600.

[0039] The connection between the fixing member 400 and the gasket 500 is achieved by screwing a screw through the gasket 500 and screwing it to the fixing member 400 .

[0040] In this embodiment, the synchronous belt mechanism further includes: a screw.

[0041] Two first reinforcement structures 402 are disposed on both sides of the fixing member 400 , and first through holes 403 are disposed on the first reinforcement structures 402 .

[0042] Two second reinforcement structures are disposed on both sides of the support rod 600 , and a first threaded hole is disposed at one end of the second reinforcement structure close to the first reinforcement structure 402 .

[0043] The central axes of the first through hole 403 and the first threaded hole are parallel to the synchronous belt 300 , and the screw passes through the first through hole 403 and is threadedly engaged with the first threaded hole.

[0044] like Figure 1 The first reinforcement structure 402 and the second reinforcement structure are shown as cylindrical structures connected at their ends.

[0045] In this embodiment, if Figure 3 The two first reinforcement structures 402 are shown to form a first groove 404 on one side of the fixing member 400 . The tooth groove 401 is disposed in the first groove 404 , and the synchronous belt 300 is disposed in the first groove 404 .

[0046] In a preferred embodiment, the first through hole 403 coincides with the projection of the synchronous belt 300 in the width direction, so that the forces applied by the synchronous belt 300 and the lifting column along the extension direction of the support rod 600 coincide.

[0047] By arranging the tooth groove 401 in the first groove 404, the force of the lifting column can directly act on the tooth surface of the synchronous belt 300. By arranging the synchronous belt 300 in the first groove 404, the extension direction of the synchronous belt 300 can be close to or overlap with the force applied by the lifting column along the extension direction of the support rod 600.

[0048] In this embodiment, if Figure 3 The width of the tooth groove 401 is matched with the width of the synchronous belt 300 .

[0049] The gasket 500 is provided with a second groove 501 , the width of the second groove 501 is matched with the width of the tooth groove 401 , the gasket 500 is arranged in the first groove 404 , and the tooth groove 401 and the synchronous belt 300 are arranged in the second groove 501 .

[0050] The synchronous belt 300 can be limited in the width direction by the concave-convex cooperation among the fixing member 400 , the tooth groove 401 and the gasket 500 , thereby improving the connection stability of the fixing member 400 , the gasket 500 and the synchronous belt 300 .

[0051] In this embodiment, if Figure 1 The second reinforcement structure shown forms a third groove 601 on one side of the support rod 600 , and the synchronous belt 300 is disposed in the third groove 601 .

[0052] In a preferred embodiment, the first threaded hole coincides with the projection of the synchronous belt 300 in the width direction, so that the forces applied by the synchronous belt 300 and the lifting column along the extension direction of the support rod 600 coincide.

[0053] The synchronous belt 300 is arranged in the second groove 501 , so that the extension direction of the synchronous belt 300 can be close to or overlap with the force applied by the lifting column along the extension direction of the support rod 600 .

[0054] In this embodiment, the synchronous belt mechanism includes: two sets of fixing members 400 and gaskets 500 .

[0055] The timing belt 300 is an open-loop timing belt 300 .

[0056] One set of fixing members 400 and gaskets 500 are connected and installed at one end of the synchronous belt 300 , and another set of fixing members 400 and gaskets 500 are connected and installed at the other end of the synchronous belt 300 . The two fixing members 400 are connected to connect the two ends of the open-loop synchronous belt 300 .

[0057] like Figure 1 As shown, screws are used to pass through the two fixing members 400 and then are screwed to the support rod 600, so that the two fixing members 400 are fixedly connected to the support rod 600, and the support rod 600 is installed while connecting the two ends of the open-loop synchronous belt 300.

[0058] In this embodiment, the synchronous belt mechanism includes: at least two groups of fixing members 400 and gaskets 500 , and two support rods 600 .

[0059] Two sets of fixing members 400 and gaskets 500 are respectively arranged on both sides of the synchronous wheel 200 and are respectively connected to the synchronous belts 300 on both sides of the synchronous wheel 200 .

[0060] like Figure 1 The two support rods 600 are respectively arranged on both sides of the synchronous wheel 200 and are respectively connected to the fixing members 400 on both sides of the synchronous wheel 200. The two support rods 600 are extended in opposite directions.

[0061] Working principle: firstly, the fixing member 400 is clamped on the tooth surface of the synchronous belt 300 through the tooth groove 401, and then a screw is used to pass through the gasket 500 and screw it with the fixing member 400 to achieve a fixed connection between the gasket 500 and the fixing member 400.

[0062] Then, a screw is used to pass through the first through hole 403 of the fixing member 400 and connect with the first threaded hole of the support rod 600 to achieve fixed connection between the fixing member 400 and the support rod 600.

[0063] Then, the fixing bracket 100 is installed on the lifting column, and the other end of the support rod 600 extending in the direction of the synchronous belt 300 is installed on the lifting column, so that the lifting column applies a force to the synchronous belt 300 along the extending direction of the support rod 600 to drive the synchronous belt 300 to move, which can make the load force parallel to the movement direction of the synchronous belt 300, reduce the local deflection of the connection between the fixing part 400 and the synchronous belt 300, and enable the synchronous belt mechanism to carry more load.

[0064] In the second embodiment, the synchronous belt mechanism of the first embodiment is used for a lifting column.

[0065] like Figure 4 The lifting column shown includes: the synchronous belt mechanism of the first embodiment, a push rod motor 700, a bottom plate 801, a middle plate 802, a top plate 803, an outer tube 804, a middle tube 805 and an inner tube 806.

[0066] The outer tube 804 is sleeved on the middle tube 805 , and the middle tube 805 is sleeved on the inner tube 806 .

[0067] The outer tube 804 is connected to the bottom plate 801 , the middle tube 805 is connected to the middle plate 802 , and the inner tube 806 is connected to the top plate 803 .

[0068] The push rod motor 700 is installed on the middle plate 802 and the top plate 803 .

[0069] The fixed bracket 100 of the synchronous belt mechanism is installed on the middle plate 802 , one end of the support rod 600 is connected to the top plate 803 , and the other end of the support rod 600 is connected to the bottom plate 801 .

[0070] When the push rod motor 700 drives the top plate 803 to move away from the middle plate 802, the inner tube 806 drives a support rod 600 to move upward, and the support rod 600 drives the synchronous belt 300 to move around the synchronous wheel 200, so that the synchronous belt 300 drives another support rod 600 to move downward, and the other support rod 600 drives the bottom plate 801 to move away from the middle plate 802, thereby increasing the distance between the top plate 803, the middle plate 802 and the bottom plate 801.

[0071] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
