[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0037] Embodiment 1:

[0038] A lifting device for building interior decoration, comprising a lifting platform 1, a base 2 and a hydraulic rod 3, wherein the hydraulic rod 3 is fixedly installed on the top of the base 2, the output end of the hydraulic rod 3 is fixedly connected to the bottom of the lifting platform 1, the bottom of the base 2 is fixedly connected with four first universal wheels 4, both sides of the base 2 are provided with adjustment blocks 5, a side of the adjustment block 5 away from the base 2 is provided with a T-shaped groove 6, the inside of the T-shaped groove 6 is slidably connected with two T-shaped blocks 7, one side of the T-shaped block 7 is fixedly connected with an auxiliary support plate 8, and the bottom of the auxiliary support plate 8 is fixedly connected with a second universal wheel 9;

[0039] The extension mechanism is fixedly arranged on the base 2 and can adjust the position of the auxiliary support plate 8 .

[0040] One implementation of the first embodiment of the present invention is as follows: the extension mechanism includes a transmission groove 10 opened inside the base 2, a motor 11 is fixedly connected to one side of the base 2, the output end of the motor 11 passes through the inside of the transmission groove 10, and is fixedly connected to a first bevel gear 12, both sides of the first bevel gear 12 are meshedly connected with the second bevel gear 13, one end of the second bevel gear 13 is fixedly connected to a first threaded rod 14, one end of the first threaded rod 14 is rotatably connected to the inner wall of the transmission groove 10 through a bearing seat, the surface of the first threaded rod 14 is transmission-connected to a moving block 15, one side of the moving block 15 is provided with a first threaded hole 16 used in conjunction with the first threaded rod 14, one side of the moving block 15 is fixedly connected to two transmission rods 17, one end of the transmission rod 17 passes through one side of the base 2, and is fixedly connected to one side of the adjustment block 5, and a supporting mechanism is provided on the top of the auxiliary support plate 8.

[0041] In this embodiment, it is considered that when the lifting device lifts the workers to a high place, the center of gravity shifts upward, the stability of the lifting device will decrease, and the lifting device is prone to shaking, which will affect the construction safety of the workers. Therefore, by setting an extension mechanism, the first bevel gear 12 can be driven to rotate by starting the motor 11, and the first bevel gear 12 drives the second bevel gear 13 to rotate. The second bevel gear 13 will drive the first threaded rod 14 to rotate around the bearing seat. During the rotation of the first threaded rod 14, the external thread on its surface will squeeze the internal thread of the first threaded hole 16, so that the two moving blocks 15 move to the side away from each other, and the moving block 15 drives the transmission rod 17 and the adjustment block 5 and other structures to move along the trajectory of the sliding block 30 and the sliding groove 31. If Figure 3 As shown, the adjustment block 5 and the auxiliary support plate 8 are unfolded, and then the second universal wheel 9 is locked. At this time, the support area of ​​the lifting device base 2 is increased, and the stability is significantly improved;

[0042] The invention solves the problem that when the lifting device lifts the workers to a high place, the center of gravity shifts upward, the stability of the lifting device decreases, the lifting device is prone to shaking, and thus affects the construction safety of the workers.

[0043] Preferably, sliding blocks 30 are fixedly connected to both sides of the moving block 15 , and a sliding groove 31 for use with the sliding blocks 30 is formed on the inner wall of the transmission groove 10 .

[0044] In this embodiment, by setting the sliding block 30 and the sliding groove 31, the internal thread of the first threaded hole 16 can be squeezed on the outer surface of the first threaded rod 14, limiting the moving trajectory of the moving block 15 and other structures, so that it can only move along the trajectory of the sliding block and the sliding groove 31, while improving its stability during the movement process.

[0045] Preferably, the two first threaded holes 16 are threads in opposite directions to each other.

[0046] In this embodiment, by setting the two first threaded holes 16 to have opposite threads, when the first threaded rod 14 rotates and cooperates with the first threaded hole 16, the two moving blocks 15 can be driven to move away from each other, thereby reducing the time required for the auxiliary support plate 8 to unfold.

[0047] Embodiment 2:

[0048] On the basis of the first embodiment, the extension mechanism in this embodiment expands the auxiliary support plate 8 to increase the support range of the lifting device, thereby improving the stability of the lifting device. However, considering that there may be potholes on the ground during interior decoration, if the second universal wheel 9 connected to the auxiliary support plate 8 is not in contact with the ground, the auxiliary support plate 8 cannot have the ability to support. In this application, the support mechanism includes a second threaded rod 18 threadedly connected to the top of the auxiliary support plate 8, a rotating block 19 is fixedly connected to the top of the second threaded rod 18, and rotating rods 20 are fixedly connected to both sides of the rotating block 19. The bottom of the second threaded rod 18 is fixedly connected to a friction block 21;

[0049] A second threaded hole 22 for use with the second threaded rod 18 is formed on the top of the auxiliary support plate 8 .

[0050] In this embodiment, it is considered that there may be potholes on the ground during the interior decoration process, and if the second universal wheel 9 connected to the auxiliary support plate 8 is not in contact with the ground, the auxiliary support plate 8 cannot have the supporting ability. Therefore, by setting a supporting mechanism, the rotating rod 20 and the rotating block 19 can be rotated by twisting, and at the same time, the second threaded rod 18 is driven to rotate in the second threaded hole 22. The second threaded rod 18 gradually moves downward along the trajectory of the second threaded hole 22, and at the same time drives the friction block 21 to move downward. When the friction block 21 is in contact with the ground, the auxiliary support plate 8 can have the supporting function;

[0051] The problem that there may be potholes on the ground during interior decoration and the auxiliary support plate 8 cannot have supporting capacity if the second universal wheel 9 connected to the auxiliary support plate 8 is not in contact with the ground is solved.

[0052] Embodiment three:

[0053] On the basis of the embodiment, this embodiment takes into account that the support mechanism needs to adjust the ground contact to achieve the support effect, but there may be some potholes in the interior decoration process, which cannot provide support points for the support mechanism. In this application, an adjustment mechanism is provided on the top of the auxiliary support plate 8, which can adjust the position of the support mechanism;

[0054] The adjustment mechanism includes a limit frame 23 fixedly connected to the top of the auxiliary support plate 8, a pulling block 24 is arranged on the top of the limit frame 23, a pulling rod 25 is fixedly connected to the bottom of the pulling block 24, the bottom of the pulling rod 25 passes through the bottom of the limit frame 23 and is fixedly connected to an extrusion block 26, the bottom of the extrusion block 26 is fixedly connected to a pin rod 27, and a plurality of pin holes 28 for use with the pin rod 27 are opened on the top of the adjustment block 5.

[0055] In this embodiment, it is considered that the support mechanism needs to be in contact with the ground to achieve the support effect, but there may be some potholes in the interior decoration process that cannot provide support points for the support mechanism. Therefore, by setting an adjustment mechanism, the pulling block 24 can be pulled upward, and the pulling block 24 drives the pulling rod 25, the squeezing block 26 and the pin rod 27 to move upward. After the pin rod 27 leaves the pin hole 28, the auxiliary support plate 8 is no longer restricted, and the position of the auxiliary support plate 8 and the support mechanism can be adjusted along the trajectory of the T-shaped block 7 and the T-shaped slot 6. When it moves to the appropriate position, the pulling block 24 is released, and the elastic force generated by the spring 29 pushes the squeezing block 26 and the pin rod 27 to move downward, so that the pin rod 27 enters the corresponding pin hole 28, thereby completing the adjustment of the support position of the support mechanism;

[0056] The invention solves the problem that the supporting mechanism needs to be in contact with the ground to achieve the supporting effect, but there may be some potholes in the interior decoration process, which cannot provide supporting points for the supporting mechanism.

[0057] Preferably, a spring 29 is sleeved on the surface of the pulling rod 25 , the bottom of the spring 29 is fixedly connected to the top of the extrusion block 26 , and the top of the spring 29 is fixedly connected to the inner wall of the limiting frame 23 .

[0058] In this embodiment, by providing a spring 29, the elastic force generated by the spring 29 can push the extrusion block 26 and the pin rod 27 to move downward, thereby achieving a reset effect.

[0059] Working principle: The user starts the motor 11 to drive the first bevel gear 12 to rotate, the first bevel gear 12 drives the second bevel gear 13 to rotate, the second bevel gear 13 drives the first threaded rod 14 to rotate around the bearing seat, and the external thread on the surface of the first threaded rod 14 will squeeze the internal thread of the first threaded hole 16 during the rotation of the first threaded rod 14, so that the two moving blocks 15 move away from each other, and the moving block 15 drives the transmission rod 17 and the adjustment block 5 and other structures to move along the trajectory of the sliding block 30 and the sliding groove 31. Figure 3 As shown, the adjustment block 5 and the auxiliary support plate 8 are unfolded, and then the second universal wheel 9 is locked. At this time, the support area of ​​the lifting device base 2 is increased, and the stability is significantly improved;

[0060] At the same time, by twisting the rotating rod 20 and the rotating block 19 to rotate, the second threaded rod 18 is driven to rotate in the second threaded hole 22, and the second threaded rod 18 gradually moves downward along the trajectory of the second threaded hole 22, and the friction block 21 is driven to move downward. When the friction block 21 contacts the ground, the auxiliary support plate 8 can have a supporting function;

[0061] And considering that the supporting mechanism needs to be in contact with the ground to achieve the supporting effect, but there may be some potholes in the interior decoration process that cannot provide support points for the supporting mechanism, by setting up an adjustment mechanism, the pulling block 24 can be pulled upward, and the pulling block 24 can drive the pulling rod 25, the squeezing block 26 and the pin rod 27 to move upward. After the pin rod 27 leaves the pin hole 28, the auxiliary support plate 8 is no longer restricted, and the position of the auxiliary support plate 8 and the supporting mechanism can be adjusted along the trajectory of the T-shaped block 7 and the T-shaped slot 6. When it moves to the appropriate position, release the pulling block 24, and the elastic force generated by the spring 29 pushes the squeezing block 26 and the pin rod 27 to move downward, so that the pin rod 27 enters the corresponding pin hole 28, thereby completing the adjustment of the supporting position of the supporting mechanism.

[0062] It should be noted that the motor 11 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art, and the specific composition and principle of the power supply of the motor 11 are clear to those skilled in the art, so they are not described in detail.
