DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In the description of the present invention, it should be noted that the directions or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0022] A high-strength jack fulcrum block, such as Figure 1 , 2 As shown, it includes a fulcrum block body 1, and a thickened strength block 2 is arranged at the right bottom of the fulcrum block body 1; the thickened strength block 2 cooperates with the right side surface of the fulcrum block body 1 to be concave inward to form a longitudinal arc-shaped strength concave surface 3; the upper back surface of the fulcrum block body 1 is concave inward to form a transverse arc-shaped strength concave surface 4.

[0023] Specifically, the invention comprises a fulcrum block body 1, a thickened strength block 2 is arranged at the bottom right side of the fulcrum block body 1; the thickened strength block 2 cooperates with the right side surface of the fulcrum block body 1 to be recessed inward to form a longitudinal arc-shaped strength concave surface 3; the upper back surface of the fulcrum block body 1 is recessed inward to form a transverse arc-shaped strength concave surface 4, so as to enhance the stability of the fulcrum block when it is under pressure by the thickened strength block 2, prevent deformation or rupture caused by uneven pressure distribution or excessive pressure, improve the bearing capacity of the fulcrum block, enable it to cope with greater loads, and reduce the stress concentration phenomenon of the fulcrum block body when it is under pressure by dispersing the pressure, thereby extending the service life. The longitudinal arc-shaped strength concave surface 3 optimizes the stress distribution of the fulcrum block when it is subjected to pressure, and at the same time enhances the overall strength of the fulcrum block. The transverse arc-shaped strength concave surface further enhances the stability of the fulcrum block when it is subjected to lateral force, prevents the fulcrum block from deforming or shifting when subjected to lateral force, effectively resists lateral force, improves the fulcrum block's ability to resist lateral pressure, and at the same time enhances the stability of the fulcrum block, reduces possible shaking or displacement during use, and improves work efficiency and safety. The transverse arc-shaped strength concave surface cooperates with the longitudinal arc-shaped strength concave surface to jointly enhance the overall strength and stability of the fulcrum block, and effectively improves the load-bearing capacity, stability and service life of the fulcrum block.

[0024] As a preferred embodiment of the above, Figure 3 As shown, two transverse fixing holes 5 are provided on the fulcrum block body 1 .

[0025] Specifically, two transverse fixing holes 5 are provided on the fulcrum block body 1 to install and fix the fulcrum block and adapt to different installation environments and requirements.

[0027] Specifically, the fulcrum block body 1 is provided with a longitudinal fixing hole 6 for installing and fixing the fulcrum block, and cooperates with the transverse fixing hole 5 to adapt to more installation environments and requirements.

[0028] As a preferred embodiment of the above, Figure 3 As shown, a groove 6 - 1 is arranged on the outer side of the longitudinal fixing hole 6 , and an arc-shaped protrusion 6 - 2 is arranged at the vertex of the groove 6 - 1 .

[0029] Specifically, a groove 6-1 is provided on the outside of the longitudinal fixing hole 6, and an arc-shaped protrusion 6-2 is provided at the vertex of the groove 6-1, thereby increasing the contact area between the fixing hole and the fastener and enhancing the fixing effect. When the fastener passes through the fixing hole and is tightened, it can fit more closely on the groove 6-1 and the arc-shaped protrusion 6-2 to form a more secure connection, and the arc-shaped protrusion 6-2 can effectively disperse the stress generated by the fastener to prevent damage caused by stress concentration, so that the fulcrum block can distribute stress more evenly when under pressure, thereby extending the service life. At the same time, the special structure formed by the groove 6-1 and the arc-shaped protrusion 6-2 can increase the locking force of the fastener and prevent loosening due to vibration or external force during use.

[0030] As a preferred embodiment of the above, Figure 1 As shown, two reinforcing ribs 7 are provided on both sides of the groove 6 - 1 on the fulcrum block body 1 .

[0031] Specifically, by providing two reinforcing ribs 7 on both sides of the groove 6 - 1 on the fulcrum block body 1 , the supporting strength of the fulcrum block is further improved.

[0032] As a preferred embodiment of the above, Figure 4 As shown, the two transverse fixing holes 5 are respectively arranged on both sides of the reinforcing rib 7 on the left side.

[0034] Specifically, the back surface of the fulcrum block body 1 is provided with a structure of an inwardly recessed weight-reducing circular hole, thereby reducing the dead weight of the fulcrum block.
