DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: an artificial weathering test box, including a box body 100, a test cavity groove is opened on the front surface of the box body 100, a placement plate 103 for placing test items is arranged inside the test cavity groove, and vertical guide pillars 104 are fixed at the four corners inside the test cavity groove. The four corners of the placement plate 103 are slidably sleeved on the guide pillars 104 to achieve height adjustment according to different test requirements. The guide pillars 104 are provided with an adjustment mechanism, and the adjustment mechanism includes:

[0023] The abutting assembly is arranged inside the placement plate 103 and abuts against the guide pillar 104, and is the first structure for achieving position limiting;

[0024] The auxiliary component is arranged at the bottom of the placement plate 103, and is separated from the clamping component. The auxiliary component is sleeved on the guide pillar 104, and is the second structure to realize the limiting function, and cooperates with the clamping component to realize the final limiting function.

[0025] In this embodiment, preferably, a through hole 103a is opened on the surface of the placement plate 103, and the tightening component includes a crown spring 105 placed on the inner side of the through hole 103a. The crown spring 105 is made of metal, and the middle part is raised toward the guide pillar 104. The whole is elastic. During adjustment, when it is subjected to thrust, it will deform itself and always keep in contact with the outer surface of the guide pillar 104. After adjusting to the appropriate position, it can automatically rebound to achieve limiting. The two ends of the crown spring 105 are outside the placement plate 103, and the crown spring 105 and the placement plate 103 are fixed by bolts to ensure the stability of the installation.

[0026] In this embodiment, preferably, the auxiliary component includes a limiting collar 106, which is installed on the bottom surface of the placement plate 103 by the cooperation of bolts and nuts. The limiting collar 106 is composed of an upper ring 106a and a lower ring 106b. A plastic clamping column 107 is passed through one end of the upper ring 106a and the lower ring 106b. An integrated clamping block 107a is provided in the middle of the clamping column 107. The inner portion of the connection between the upper ring 106a and the lower ring 106b is A moving groove 106b-2 is also provided, and the longitudinal section of the moving groove 106b-2 is an isosceles trapezoid, while the longitudinal section of the pressing block 107a is a rectangle. In the limiting process, when adjusted to a suitable position, the crown spring 105 rebounds to complete the initial limiting, and then the pressing column 107 is pushed toward the inner side of the limiting collar 106. At this time, the pressing block 107a is restricted by the shape of the pressing block 107a and 106a-2, and the inner wall of the pressing block 107a and 106a-2 is pressed against each other, and the damping is increased by deformation, thereby To ensure that the end face of the clamping column 107 is tightly pressed against the guide pillar 104, its own position will not be offset, the moving groove 106b-2 is pressed against the clamping block 107a, and the crown spring 105 is used to limit and adjust the position of the placement plate 103. A convex plate 106b-1 is fixed on the top of the lower ring 106b, and a mounting groove 106a-1 is opened at the bottom of the upper ring 106a. The convex plate 106b-1 is engaged with the mounting groove 106a-1. When the clamping column 107 is placed in the early stage When installing, first place the clamping column 107 in the movable groove 106b-2 on the lower ring 106b, and then stagger the upper ring 106a and the lower ring 106b so that the protruding plate 106b-1 can be inserted into the installation groove 106a-1, and then push the upper ring 106a toward the position of the protruding plate 106b-1, so that the installation groove 106a-1 and the protruding plate 106b-1 are staggered and engaged to complete the limiting. Finally, lower the upper ring 106a and the lower ring 106b and fix them by bolts.

[0027] In this embodiment, preferably, the longitudinal sections of the mounting groove 106a-1 and the protruding plate 106b-1 are both hook-shaped, and the inner width of the mounting groove 106a-1 is greater than the width of the protruding plate 106b-1, thereby facilitating the early insertion of the protruding plate 106b-1. The inner diameter of the limiting ring 106 is greater than or equal to the outer diameter of the guide pillar 104, which is convenient for insertion, and there is a spacing between the limiting ring 106 and the end of the crown spring 105.

[0028] In this embodiment, preferably, the front surface of the box body 100 is also connected to a cabinet door 101 through a hinge, which is used to close the entire test box during testing. An operation panel 102 for realizing the entire test operation function is also provided on the front surface of the box body 100.

[0029] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
