DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-4 The utility model provides a technical solution: an adjustable impact-resistant high-load bracket, comprising a mounting plate 1, a bracket 2, a first worm wheel 3, a first worm 4, a first limit block 5, a fixed block 6, a movable plate 7, a connecting plate 8, a locking screw 9, a limit plate 10, a linkage plate 11, a clamping plate 12, an anti-slip pad 13, a second worm wheel 14, a second worm 15 and a second limit block 16. When the adjustable impact-resistant high-load bracket is used, Figure 1 , Figure 2 and Figure 3 First, according to the needs of the use occasion, position, etc., the mounting plate 1 can be rotated and fixedly connected to the first worm 4 that is non-detachably connected and engaged in the first limit block 5, so that the first worm 4 can rotate under the engagement limit of the first limit block 5. Since the upper side of the middle part of the first worm 4 is meshedly connected with the first worm wheel 3 that is fixedly connected to the support plate 2, the support plate 2 is rotatably connected in the mounting plate 1. Therefore, through the rotation of the first worm 4, it is convenient for the first worm wheel 3 to drive the support plate 2 to rotate in the mounting plate 1, so as to achieve the purpose of adjusting the angle between the fixed support plate 2 and the mounting plate 1 through the meshing self-locking of the first worm wheel 3 and the first worm 4, so as to facilitate the screw to be installed through the outer end of the mounting plate 1, and the bracket arm is installed and fixed;

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The locking screw 9 connected with the threaded connection on the inner side of the right end of the movable plate 7 can be turned to disconnect the front end of the locking screw 9 from the nested fit of the fixed connecting plate 8 outside the pallet 2, so that the movable plate 7 and the connecting plate 8 can be moved under the restriction of the fixing block 6 and the pallet 2 respectively during the process of adjusting the angle between the pallet 2 and the mounting plate 1. After the angle adjustment between the pallet 2 and the mounting plate 1 is completed, the locking screw 9 can be turned again to make the front end of the locking screw 9 and the connecting plate 8 tightly fit and connect, so as to achieve the purpose of fixing the connecting plate 8 and the movable plate 7, thereby facilitating the strengthening of the connection between the pallet 2 and the mounting plate 1, so that the bracket arm has good impact resistance and high load performance.

[0026] like Figure 1 , Figure 2 and Figure 4 Then, the workpieces such as cables and pipes can be placed on the upper middle side of the support arm support plate 2 so that they are located on the inner side of the clamping plate 12. Then, the second worm 15 fixedly connected to the second limit block 16 under the support plate 2 can be rotated, so that the second worm 15 can rotate under the engagement limit of the second limit block 16. Since the front side of the second worm 15 is meshedly connected with the second worm wheel 14 fixed to the limiting plate 10, the limiting plate 10 is rotatably connected to the inner middle side of the support plate 2, and the inner sides of the front and rear ends of the limiting plate 10 are symmetrically rotated with the linkage plate 11, and the outer ends of the linkage plate 11 are symmetrically rotated. A clamping plate 12 is rotatably connected to the support plate 2 and is inserted through the clamping plate 2. Therefore, through the rotation of the second worm 15, the second worm gear 14 can drive the limiting plate 10 to rotate in the support plate 2, so that the limiting plate 10 drives the clamping plate 12 to move in the opposite direction under the clamping limit of the support plate 2 through the linkage plate 11, so that the clamping plate 12 can drive the anti-skid pad 13 fixed on the upper side of its inner end to move until the anti-skid pad 13 is tightly fitted to the outside of the workpiece, thereby achieving the purpose of clamping and limiting the workpiece to prevent it from falling off.
