DETAILED DESCRIPTION

[0026] 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 of 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.

[0027] Figure 1 The schematic diagram of the structure of the angle-adjustable layer support device in the utility model is shown. Figure 2 An exploded view of the angle-adjustable layer support device of the utility model is shown; Figure 3 The schematic diagram of the structure of the angle plate in the utility model is shown. Figure 4 The schematic diagram of the structure of the fixing mechanism in the utility model is shown. The adjustable angle layer support device comprises: a fixing mechanism 1 and an angle plate 2. The angle plate 2 is an L-shaped plate, and the angle plate 2 is rotatably connected to the fixing mechanism 1.

[0028] The angle plate 2 includes a vertical plate 22 and a horizontal plate 21. The vertical plate 22 is provided with a first matching area 221, a second matching area 222 and a rotation hole 223. The second matching area 222 is located above the rotation hole 223, and the first matching area 221 is located above the second matching area 222. The first matching area 221 is provided with a plurality of first fixing holes 2211, and the second matching area 222 is provided with a plurality of second fixing holes 2221. The angle plate 2 is connected to the fixing mechanism 1 based on the rotation hole 223. In this embodiment, the first matching area 221 is provided with seven first fixing holes 2211, and the second matching area 222 is provided with seven second fixing holes 2221, and the straight line where the center of the first fixing hole 2211 and the center of the rotation hole 223 are located must pass through the center of one of the second fixing holes 2221. The fixing mechanism 1 is provided with a positioning ball 14 and a spring 15, and the positioning ball 14 is stuck in any of the second fixing holes 2221 under the pressure of the spring 15. The spring 15 exerts a force on the positioning ball 14 , so that the positioning ball 14 can abut against the angle plate 2 , ensuring that the positioning ball 14 can be stuck in the corresponding second fixing hole 2221 .

[0029] It should be noted that the vertical plate 22 is a semicircular vertical plate 22, and the root of the vertical plate 22 is connected to the root of the horizontal plate 21 to form a whole, so that the vertical plate 22 and the horizontal plate 21 form an L-shaped plate. When the plate to be installed is placed on the angle plate 2, the vertical plate 22 can limit its horizontal movement range, and the horizontal plate 21 can limit its vertical movement range.

[0030] Furthermore, the fixing mechanism 1 is provided with a first connection hole 11, a second connection hole 12 and a third connection hole 13; the first connection hole 11 is correspondingly arranged in the first matching area 221, the second connection hole 12 is correspondingly arranged in the second matching area 222, and the third connection hole 13 is correspondingly arranged at the rotating hole 223. The third connection hole 13 is used to rotatably connect the fixing mechanism 1 and the angle plate 2, so that the angle plate 2 can rotate with the third connection hole 13 as the center of the circle, the second connection hole 12 is used to fix the connection ball at the second connection hole 12, and the first connection hole 11 is used to fix the angle plate 2 and the fixing mechanism 1, and is used. The first matching area 221 is an arc groove, the second matching area 222 is also an arc groove, and the edge of the first matching area 221 protrudes upward to form a first limiting end face, and the first limiting end face is used to limit the rotation angle of the angle plate 2.

[0031] Furthermore, a first connecting groove 2212 is arranged between two adjacent first fixing holes 2211. In the present embodiment, six first connecting grooves 2212 are arranged in the first matching area 221. The six first connecting grooves 2212 connect the seven first fixing holes 2211, thereby ensuring that the pin inserted into the first fixing hole 2211 and the first connecting hole 11 can change the matching position with the first matching area 221, thereby reducing the steps of adjusting the angle after pulling out the pin and improving the efficiency of converting the angle.

[0032] Specifically, when the latch is inserted into the first fixing hole 2211 and then into the first connecting hole 11, an external force can be used to drive the angle plate 2 to rotate with the third connecting hole 13 as the center, thereby changing the matching position of the first matching area 221 and the latch. When the angle plate 2 is rotated to the corresponding position, the latch is screwed into the first connecting hole 11 to strengthen the connection between the angle plate 2 and the fixing mechanism 1.

[0033] Furthermore, control plates 211 are extended from both ends of the horizontal plate 21 in a direction away from the vertical plate 22. The control plates 211 can be used to adjust the angle of the angle plate 2 or to strengthen the bearing capacity of the horizontal plate 21 on the object to be carried. The control plates 211 increase the contact area between the horizontal plate 21 and the object to be carried, so that the force distribution of the horizontal plate 21 on the object to be carried is more uniform, reducing local stress concentration, thereby reducing the risk of deformation of the object, and increasing the contact area can improve stability and reduce the risk of sliding or overturning due to external factors.

[0034] Furthermore, each of the control panels 211 is provided with a through hole 2111. The through holes 2111 on the control panels 211 can be used to hang weights to accurately adjust the angle of the angle plate 2, that is, weights of different weights are hung on the control panels 211 at both ends to adjust the angle of the angle plate 2, and the heights of the two ends of the angle plate 2 are accurately adjusted by using the weights, thereby adjusting the rotation angle of the angle plate 2, which is conducive to adjusting multiple angle plates 2 to the same angle. Secondly, the through holes 2111 can also use screws to reinforce the connection between the control panel 211 and the objects placed on the control panel 211, ensuring that the objects can be fixedly connected to the angle plate 2.

[0035] Furthermore, a gasket 3 is provided between the third connection hole 13 and the rotation hole 223. The gasket 3 forms a preset interval between the angle plate 2 and the fixing mechanism 1, and the preset interval can keep a certain distance between the angle plate 2 and the fixing mechanism 1, so as to avoid direct contact between the angle plate 2 and the surface of the fixing mechanism 1, resulting in scratches between the angle plate 2 and the surface of the fixing mechanism 1 during the process of adjusting the angle of the angle plate 2, which is conducive to reducing the scratches between the angle plate 2 and the surface of the fixing mechanism 1, thereby reducing the risk of scratches on the surfaces of the angle plate 2 and the fixing mechanism 1.

[0036] Furthermore, the radius of the positioning ball 14 is R1, the radius of the second fixing hole 2221 is R2, and the constraint relationship between R1 and R2 is R1>R2. When the positioning ball 14 moves into any of the second fixing holes 2221, the surface of the positioning ball 14 fits with the second fixing hole 2221, and the spring 15 exerts a force on the positioning ball 14 so that a part of the positioning ball 14 is inserted into the second fixing hole 2221. Then, when the positioning ball 14 leaves the second fixing hole 2221, the positioning ball 14 exerts a force on the spring 15 so that the spring 15 is compressed until the positioning ball 14 moves into the next fixing hole. The spring 15 exerts a force on the positioning ball 14 so that a part of the positioning ball 14 is inserted into the second fixing hole 2221. In this process, the positioning ball 14 will cause a sense of stagnation when entering the corresponding second fixing hole 2221. This sense of stagnation can remind the user that the angle plate has rotated a certain angle.

[0037] A specific implementation method is to use the latch to insert the first fixing hole 2211, and then insert it into the first connecting hole 11, and use external force to drive the angle plate 2 to rotate with the third connecting hole 13 as the center, thereby changing the matching position of the first matching area 221 and the latch, that is, press the corresponding control plate 211 with both hands or hang a weight on the corresponding control plate 211, thereby rotating the angle plate 2. During this rotation process, the positioning ball 14 will move between different second fixing holes 2221. When the positioning ball 14 enters any of the second fixing holes 2221, it will cause a sense of stagnation to prompt the user to rotate a certain angle, and then the latch is inserted into the first fixing hole 2211 again, and the latch restricts the movement of the first fixing hole 2211 to prevent the angle plate 2 from rotating spontaneously due to the influence of gravity. After adjusting the angle of the angle plate 2, place the storage plate on two opposite angle plates 2, and use screws to fix the angle plate 2 and the storage plate through the through holes on the control board, thereby increasing the possibility of placing items on the storage plate from different directions.

[0038] refer to Figure 2 and Figure 4 The fixing mechanism 1 comprises: an outer shell 16, a braking unit 17, a control unit 18 and a limiting unit 19; the limiting unit 19 is fixedly connected to the control unit 18, the braking unit 17 brakes the control unit 18, and a curved surface 191 is arranged on the side wall of the limiting unit 19. The braking unit 17, the control unit 18 and the limiting unit 19 are all arranged in the outer shell 16, and the outer shell 16 protects these three units, reducing the risk of these three units being unable to operate normally due to external influences. The braking unit 17 is used to reversely brake the control unit 18, and a switch lock 164 is provided between the braking unit 17 and the control unit 18. The switch lock 164 is used to control the usage of the braking unit 17 and the control unit 18. When the switch lock 164 is removed from the outer shell 16, the control unit 18 can control the movement of the braking unit 17. When the switch lock 164 is located between the braking unit 17 and the control unit 18, the braking unit 17 and the control unit 18 have no movable range, so that the two cannot interact with each other.

[0039] Furthermore, a guide column 161 is provided on one side of the outer shell 16, and a receiving groove 162 is provided on the other side of the outer shell 16, and a roller 163 is provided in the receiving groove 162. The guide column 161 is used to help the fixing mechanism 1 move in the designated slide groove, and ensure that the fixing mechanism 1 can move along the inner wall of the slide groove, reducing the risk of the fixing mechanism 1 deviating from the designated slide groove during movement. The roller 163 is used to move in the slide groove, reduce the friction between the outer shell 16 and the slide groove, and enable the fixing mechanism 1 to move more smoothly in the designated slide groove.

[0040] Furthermore, a roller 163 is disposed in the receiving groove 162, and the limiting unit 19 is driven by the control unit 18 to be in contact with the roller 163 or the limiting unit 19 is driven by the control unit 18 to be in non-contact with the roller 163. When the control unit 18 is driven to move downward by an external force, the control unit 18 drives the limiting unit 19 to move downward, and the limiting unit 19 moves downward so that its curved surface 191 contacts the roller 163, thereby increasing the contact area between the roller 163 and the curved surface 191, and increasing the friction between the roller 163 and the curved surface 191, thereby preventing the roller 163 from rotating. When the control unit 18 is driven to move upward by an external force, the control unit 18 drives the limiting unit 19 to move upward. The limiting unit 19 moves upward so that its curved surface 191 is in a non-contact state with the roller 163, so that the limiting unit 19 has no friction force on the roller 163, and the roller 163 can rotate.

[0041] To summarize, the utility model sets a first matching area, and the first matching area can prevent the fixing pin from moving while the angle plate rotates to the corresponding angle, thereby reducing the steps of adjusting the angle and improving the user experience; a positioning ball and a spring are also set, and when the positioning ball enters from one second fixing hole to the next second fixing hole, the spring exerts a force on the positioning ball, so that the positioning ball is completely fitted with the edge of the second fixing hole, thereby causing a sense of stagnation, and this sense of stagnation can prompt the user to rotate a certain angle.
