Detailed Description

In order to clearly understand the technical solution of the present invention, the present invention is further illustrated by the following embodiments in combination with the accompanying drawings.

Example 1:

as shown in fig. 1 and fig. 2, the weight block joint provided by this embodiment includes an embedded base 1 molded by casting high-strength plastic and a cladding body 2 made of wear-resistant material and cladding the embedded base 1, as shown in fig. 3, the embedded base 1 includes a front surface 3, a back surface 4, a top surface 5, a bottom surface 6 and two side surfaces 7, the front surface 3 is provided with a first circular hole 8 at the center, two sides are provided with protrusions 9, the protrusions 9 are higher than the cladding body 2, the front surface 3 is further provided with a first hole slot 10, a second hole slot 11 and a third hole slot 12, the number of the first hole slot 10 is equal to the number of the protrusions 9 along the intersecting line direction of the front surface 3 and the top surface 5, starting from the top surface 5, the number of the second hole slot 11 is equal to the number of the bottom surface 3 and the intersecting line direction of the bottom surface 6, starting from the bottom surface 6, the number of the third hole slot 12 is equal, the top surface 5 and the bottom surface 6 are symmetrically provided with fourth hole grooves 13 with the number not less than one, the fourth hole grooves 13 are distributed along the direction of the intersection line of the top surface 5 and the back surface 4, the fourth hole grooves start from the back surface 4, the two side surfaces 7 are symmetrically provided with fifth hole grooves 14 with the number not less than one, the fifth hole grooves 14 are equally distributed along the direction of the intersection line of the side surfaces 7 and the back surface 4, the fifth hole grooves start from the back surface 4, the coating body 2 is poured on the embedded base body 1, the center is provided with a second round hole 15, the second round hole 15 is centrally symmetrical to the first round hole 8 and is larger than the first round hole 8, and the first hole groove 10, the second hole groove 11, the third hole groove 12, the fourth hole groove 13 and the fifth hole groove 14 are.

Through the design, the first hole groove 10, the second hole groove 11, the third hole groove 12, the fourth hole groove 13 and the fifth hole groove 14 are filled when the cladding body 2 is poured, so that the contact area between the cladding body 2 and the embedded base body 1 is larger, the generated adhesive force is larger, the separation is not easy, and the mutual embedding is firm and fixed.
