[0034] Such as Figures 1-4As shown in the figure, an adjustable ball wall barrier module mainly includes: a bottom plate 1, a ball head assembly 3, and a fixing member.

[0035] The bottom plate 1 is arranged as a rectangular plate, and fixing holes 11 are provided at the four corners of the bottom plate 1. The fixing holes 11 are preferably round holes, which are convenient for processing. Bolts are inserted through the fixing holes 11 at the four corners of the bottom plate 1, and the bottom plate 1 can be fixedly installed on the track ground. Two parallel guide rails 2 are provided on the bottom plate 1, and a pressure groove 20 is symmetrically arranged on the two guide rails 2 for the convex edge 301 on the base 30 to be arranged. Among them, a plurality of bolt holes 21 are provided along the length direction of the guide rail 2, and a plurality of bolts respectively pass through the plurality of bolt holes 21 to detachably fix the guide rail 2 on the bottom plate 1. The two guide rails 2 are respectively fixed on the bottom plate 1 through a plurality of bolts, ensuring reliable fixation of the guide rail 2 and ensuring that the ball head assembly 3 will not detach from the bottom plate 1 upward.

[0036] The ball head assembly 3 is arranged on the bottom plate 1 and includes a base 30, a plurality of cushion plates 31, and a ball head 32 arranged in sequence from bottom to top. The radius of the ball head 32 is 150 mm, which is the wall barrier. The base 30 is located between the two guide rails 2; when the base 30 slides relative to the guide rails 2, the setting position of the ball head assembly 3 on the bottom plate 1 can be adjusted. The operator can adjust the position of the ball head assembly 3 on the bottom plate 1 according to the test requirements, and the adjustment is convenient. After adjusting the position, the fixing member (a fixing bolt, not shown in the figure) passes through the base 30 and the bottom plate 1 for detachable fixed connection to fix the base 30 on the bottom plate 1.

[0037] Specifically, a convex edge 301 extends outwards from both sides of the base 30 respectively. One convex edge 301 is in sliding fit with one guide rail 2, and the other convex edge 301 is in sliding fit with the other guide rail 2. Pressure grooves 20 are provided on the two guide rails 2, and the two convex edges 301 respectively extend into the two pressure grooves 20. The two guide rails 2 limit the upward detachment of the base 30 from the bottom plate 1. One convex edge 301 is limited by the pressure groove 20 of one guide rail 2, and the other convex edge 301 is limited by the pressure groove 20 of the other guide rail 2, preventing the ball head assembly 3 from detaching from the bottom plate 1 upward during the test.

[0038] A plurality of fixing brackets 302 are provided on the base 30, and through slots 302A are provided on the fixing brackets 302. A plurality of threaded holes 10 are provided on the bottom plate 1 along the length direction of the guide rail 2. The fixing member is a fixing bolt, and the fixing bolt passes through the through slot 302A and is detachably fixed in the threaded hole 10 to fix the base 30 on the bottom plate 1. Among them, the through slot 302A is a long slot. The setting of the long slot facilitates the connection of the fixing bolt to the threaded hole 10 on the bottom plate 1. That is, after sliding and adjusting the position of the ball head assembly 3 on the bottom plate 1 along the guide rail 2, no matter where the ball head assembly 3 stops between the two end threaded holes 10, it is convenient for the fixing bolt to pass through the long slot and be threadedly connected to the threaded hole 10. Further, the fixing brackets 302 are arranged on both sides of the base 30, and there are four in total. The two sides of the base 30 are cooperatively limited with the guide rail 2 through the convex edges 301, and the other two sides of the base 30 are fixed to the fixing brackets 302 through the fixing bolts, ensuring the reliable fixation of the ball head assembly 3. The base 30 has multiple fixable positions and is convenient to fix.

[0039] During the actual use process, in this embodiment, two guide rails 2 are arranged in parallel on the bottom plate 1. When the base 30 of the ball head assembly 3 slides along the guide rail 2, the setting position of the ball head assembly 3 on the bottom plate 1 can be adjusted, that is, the position of the ball head 32 can be adjusted, so as to be applicable to different test scenarios.

[0040] More specifically, several cushion plates 31 include cushion plates 31 with various different thicknesses, and one or more of the cushion plates 31 are arranged between the base 30 and the ball head 32 to adjust the height of the ball head 32. According to actual needs, the cushion plates 31 to be laid are selected to be applicable to different test scenarios. Among them, the thicknesses of the several cushion plates 31 include 1 mm, 2 mm, 4 mm, 8 mm, and 16 mm. For example, the heights that can be raised by these different cushion plates 31 and their combinations include: 1 mm, 2 mm, 3 mm (1 mm + 2 mm), 4 mm, 5 mm (1 mm + 4 mm), 6 mm (2 mm + 4 mm), 7 mm (1 mm + 2 mm + 4 mm), 8 mm, 9 mm (1 mm + 8 mm), 10 mm (2 mm + 8 mm), 11 mm (1 mm + 2 mm + 8 mm), 12 mm (4 mm + 8 mm), 13 mm (1 mm + 4 mm + 8 mm), 14 mm (2 mm + 4 mm + 8 mm), 15 mm (1 mm + 2 mm + 4 mm + 8 mm), 16 mm, 17 mm (1 mm + 16 mm), 18 mm (2 mm + 16 mm), 19 mm (1 mm + 2 mm + 16 mm), 20 mm (4 mm + 16 mm), 21 mm (1 mm + 4 mm + 16 mm), 22 mm (2 mm + 4 mm + 16 mm), 23 mm (1 mm + 2 mm + 4 mm + 16 mm), 24 mm (8 mm + 16 mm), 25 mm (1 mm + 8 mm + 16 mm), 26 mm (2 mm + 8 mm + 16 mm), 27 mm (1 mm + 2 mm + 8 mm + 16 mm), 28 mm (4 mm + 8 mm + 16 mm), 29 mm (1 mm + 4 mm + 8 mm + 16 mm), 30 mm (2 mm + 4 mm + 8 mm + 16 mm), and 31 mm (1 mm + 2 mm + 4 mm + 8 mm + 16 mm). That is, the height range that can be raised by 5 cushion plates 31 with different thicknesses is 1 mm to 31 mm, and the applicable range is wide. Among them, the bottom of the ball head 32 has a ball head fixing plate 320 detachably and fixedly connected thereto, and the ball head fixing plate 320 is detachably and fixedly connected to the gasket and the base 30.

[0041] During actual use, several cushion plates 31 with different thicknesses are also arranged between the base 30 and the ball head 32. According to different combinations of cushion plates 31 with different thicknesses and increasing or decreasing the cushion plates 31, the height of the ball head 32 can be adjusted to further improve the test scenarios applicable to the ball wall barrier module.

[0042] In this solution, the position of the ball head assembly of the ball wall barrier module is adjustable, and the height of the ball head 32 is adjustable, with a wide applicable range.
