DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figure 1 In this embodiment, a building jack with adjustable supporting force includes a base 1. An anti-sliding block is fixed to the bottom of the base 1. The bottom of the anti-sliding block is relatively softer than metal and the ground, and can fit the ground to increase the contact area of ​​the upper mechanism and improve friction. The anti-sliding block is a hard rubber block. The hard rubber has both supporting force and is wear-resistant and corrosion-resistant, which can greatly increase the supporting stability.

[0021] In addition, the top of the base 1 is rotatably connected to a rotating mechanism 2, which is used to drive the mechanism to rotate and thus change the height. It should be noted that the rotating mechanism 2 includes a rotating column rotatably connected to the top of the base 1 and fixed to the supporting threaded rod 3. A rotating disk is fixed to the outer surface of the rotating column. The rotation of the rotating disk can drive the rotating column inside to rotate, thereby driving the supporting threaded rod 3 to rotate.

[0022] It should be noted that a stabilizing rod is fixed to the bottom of the rotating disk, which passes through the inside of the base 1 and is slidably connected thereto. The stabilizing rod can increase the multi-angle support of the outer surface of the rotating disk to make its operation more stable. Handles are fixed on both sides of the rotating disk. The handles can provide a gripping point so that people can turn the device by hand to make the mechanism rotate under force. An anti-slip rubber sleeve is fixed to the outer surface of the handle. The anti-slip rubber sleeve can increase the friction of the outer surface and increase the pressure area of ​​the hand by deformation, making the grip more firm and improving the grip comfort.

[0023] Furthermore, a supporting threaded rod 3 is fixed to the top of the rotating mechanism 2, and a supporting column 4 is threadedly connected to the outer surface of the supporting threaded rod 3. The supporting column 4 is held by hand to keep it stationary, and the rotating mechanism 2 can be rotated to make it rise or move down due to the thread engagement force. An adjusting threaded rod 5 is fixed to the top of the supporting column 4. It should be noted that a buffer pad 6 is fixed to the top of the adjusting threaded rod 5, and the buffer pad 6 can buffer the adjusting threaded rod 5 to prevent it from colliding with the supporting mechanism 7.

[0024] In addition, the outer surface of the adjusting threaded rod 5 is threadedly connected to a supporting mechanism 7, which is used to adjust the elastic supporting force. A supporting plate 8 for supporting the upper object is fixed on the top of the supporting mechanism 7. It should be noted that stabilizing ears are fixed on the left and right sides of the supporting plate 8, and a rest pad 9 is fixed on the top of the supporting plate 8. The rest pad 9 is made of rubber and can fit the supported object firmly with its soft texture.

[0025] During operation, hold the support column 4 with your hand and rotate the rotating mechanism 2 to drive the supporting threaded rod 3 to rotate and drive the support column 4 to rise or fall, and adjust the height so that it can move up or down on the outer surface of the adjusting threaded rod 5 by rotating the supporting mechanism 7, thereby changing the size of its release elastic force.

[0026] See also Figure 2-3 In order to change the supporting force of the top support, the supporting mechanism 7 in this embodiment includes a bottom plate 701 threadedly connected to the outer surface of the adjusting threaded rod 5. The rotation of the bottom plate 701 can make it affected by the thread engagement force and slide up and down on the outer surface of the adjusting threaded rod 5. A plurality of linkage rods 702 are fixed to the outer surface of the bottom plate 701. The linkage rods 702 are used to support the rotating ring 703. The rotating ring 703 is fixed on the opposite side of the plurality of linkage rods 702. The rotating ring 703 can provide a gripping point. By rotating the rotating ring 703, the plurality of linkage rods 702 can be driven to rotate.

[0027] In addition, the rotating ring 703 is used to provide a gripping point to facilitate the rotation of the mechanism. Elastic components 704 are fixed on all four sides of the top of the bottom plate 701. The larger the scale of the compression of the elastic components 704, the stronger its elastic supporting force. A top plate 705 is fixed on the top of the four elastic components 704. It should be noted that the elastic component 704 includes a hollow rod 7041 fixed to the top of the bottom plate 701. The interior of the hollow rod 7041 is a hollow structure that can accommodate the sliding of the solid rod 7042. The inner surface of the hollow rod 7041 is slidably connected to the solid rod 7042 fixed to the top plate 705. After being squeezed, the solid rod 7042 slides into the inner cavity of the hollow rod 7041, shortening the total length of the two, thereby changing their total length and squeezing the spring 7044 below.

[0028] A limiting plate 7043 is fixed at the bottom of the solid rod 7042. The limiting plate 7043 can limit the sliding of the solid rod 7042 and prevent it from completely sliding out of the hollow rod 7041. A spring 7044 fixed to the hollow rod 7041 is fixed at the bottom of the limiting plate 7043. The spring 7044 is elastically deformed when squeezed, and continuously accumulates elastic force, and reacts to the top plate 705.

[0029] It should be additionally explained that a sliding groove 7045 is provided on the outer surface of the hollow rod 7041, and the sliding groove 7045 can limit the sliding ring 7047. A protective cover 7046 is fixed on the top of the top plate 705 and is sleeved on the outer surface of the hollow rod 7041. The protective cover 7046 can protect the internal mechanism from being exposed. A sliding ring 7047 located inside the sliding groove 7045 is fixed on the inner surface of the protective cover 7046. The sliding ring 7047 slides inside the sliding groove 7045, so that it can be embedded in the interior of the solid rod 7042 to complete the limiting.

[0030] In general, one hand holds the rotating ring 703 and rotates it, driving the multiple linkage rods 702 to rotate and causing the bottom plate 701 to rotate, and move up or down on the outer surface of the adjusting threaded rod 5, changing the contact distance between the adjusting threaded rod 5 and the top plate 705, thereby changing the degree of elastic deformation of the spring 7044 under compression.

[0031] The working principle of the above embodiment is:

[0032] (1) When adjusting the support force, one hand holds the rotating ring 703 and rotates it, driving the multiple linkage rods 702 to rotate and causing the bottom plate 701 to rotate, and moves up or down on the outer surface of the adjusting threaded rod 5, changing the contact distance between the adjusting threaded rod 5 and the top plate 705, thereby changing the support to release the elastic support force. When supporting, the solid rod 7042 slides into the inner cavity of the hollow rod 7041, shortening the total length of the two, and squeezing the spring 7044. The spring 7044 is squeezed and elastically deformed, and continues to accumulate elastic force, and reacts to the top plate 705. The size of the support force can be adjusted according to the weight of the heavy object to be supported, thereby providing stable support for the upper mechanism and being safe to use.

[0033] (2) When adjusting the support height, hold the support column 4 with one hand and hold the handle with the other hand and turn it so that it can drive the rotating disk to rotate, which in turn drives the rotating column on the inner surface to rotate, and drives the upper support threaded rod 3 to rotate. The threaded engagement force drives the support column 4 to rise or fall, thereby adjusting its support height.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
