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] Example: See Figure 1 , the utility model provides a technical solution: a portable elevator mounting bracket.

[0025] Among them, side strip holes 101 are opened on both sides of the front of the vertical frame 1, and nut pressing plates 102 are opened near the outer sides of the side strip holes 101. A fixing plate 104 is fixedly connected near the top and bottom of the back of the vertical frame 1. A rotating shaft 103 is installed at the center of the bottom fixing plate 104. A connecting frame 201 is sleeved and installed on the surface of the rotating shaft 103. A rotating shaft through hole 202 is opened through the connecting frame 201 near the back. The rotating shaft 103 passes through the center of the rotating shaft through hole 202. An extension frame 2 is sleeved on the outer side of the connecting frame 201. The extension frame 2 Movable holes 1 203 are opened on both sides, movable holes 204 are opened on both sides of the connecting frame 201, and locking screws 1 205 are installed through the centers of the movable holes 1 203 and the movable holes 204. An oblique bracket 3 is installed inside the vertical frame 1 near the front, and a locking screw 2 301 is installed horizontally through the top of the oblique bracket 3, and the locking screw 2 301 passes through the center of the side strip hole 101, and a locking screw 3 302 is installed horizontally through the bottom of the oblique bracket 3, and the locking screw 3 302 passes through the center of the movable hole 204.

[0026] In this embodiment, the top of the oblique bracket 3 is installed in the vertical frame 1 by the locking screw 2 301, and the locking screw 2 301 and the nut on the screw are pressed into the nut pressure edge grooves 102 on both sides. When the locking screw 2 301 is locked, the plates on both sides of the vertical plate 1 are squeezed to clamp the middle oblique bracket 3 to prevent it from rotating. The extension frame 2 is generally stored on the back of the vertical frame 1. The extension frame 2 is rotated counterclockwise and rotated 270° around the rotating shaft 103 as the center axis. The extension frame 2 can slide forward on the connecting frame 201 to extend the length of the entire extension frame 2. The connecting frame 201 and the extension frame 2 are fixed by locking the locking screw 1 205, and the extension frame is fixed by the same method as the locking screw 2. 2 and the connecting frame 201, thereby inserting the bottom of the oblique bracket 3 into the extension frame 2, and aligning the movable hole 204 and the hole at the bottom of the oblique bracket 3, passing the locking screw 302, and fixing the oblique bracket 3 on the extension frame 2 after locking, so that the vertical frame 1, the extension frame 2 and the oblique bracket 3 form a triangle, and one side of the vertical frame 1 fits the vertical surface, thereby generating a supporting force for it; remove the locking screw 302, rotate the extension frame 2 clockwise until the bottom surface fits the back of the vertical frame 1, and completely place the oblique bracket 3 inside the front of the vertical frame 1, thereby completing the storage of the entire installation bracket, facilitating the recovery and reuse of the installation bracket, and improving the portability of the device.

[0027] Among them, the locking screw three 302 can be pulled out from the bottom of the inclined bracket 3.

[0028] In this embodiment, the oblique bracket 3 can be placed into the extension frame 2 only by pulling out the locking screw 302. The oblique bracket 3 is fixed to the extension frame 2 by locking the locking screw 302. When the mounting bracket is folded up, the oblique bracket 3 is retracted into the vertical frame 1, and the locking screw 302 can be inserted into the bottom hole of the oblique bracket 3 in the side strip hole 101 to prevent the locking screw 302 from being lost.

[0029] The vertical frame 1, the extension frame 2 and the connecting frame 201 are all made of U-shaped plates.

[0030] In this embodiment, the inner cavity of the U-shaped plate is convenient for storage, and two U-shaped plates of different sizes are also convenient for fitting together. The inner cavity of the vertical frame 1 is used to install the oblique bracket 3, and the inner width of the U-shaped plate of the extension plate 2 is the same as the outer width of the U-shaped plate of the connecting frame 201, so that the connecting frame 201 can slide inside the extension plate 2, and the movable hole 1 203 and the movable hole 2 204 of the two are aligned and fixed through the locking screw 1 205.

[0031] The fixing plate 104 is L-shaped, and a mounting hole is formed on a short side.

[0032] In this embodiment, the fixing plate 104 is welded to the vertical frame 1. A cavity is provided at the bottom of the vertical frame 1 to facilitate the rotation of the extension frame 2. The fixing plate 104 at the bottom is provided with an oblique chamfer to increase the connection area with the vertical frame 1. Fastening screws can be installed in the mounting hole to lock it on the support surface.

[0033] The distance from the bottom of the side strip hole 101 to the bottom of the vertical frame 1 is greater than the height of the connecting frame 201 .

[0034] In this embodiment, the side strip holes 101 need to avoid the turned-over connecting frame 201 .

[0035] When the extension frame 2 rotates to the rightmost side, the bottom surface of the extension frame 2 is parallel to the bottom surface of the vertical frame 1 .

[0036] In this embodiment, the bottom surfaces of the two are parallel, which increases the contact area between the bottom surface of the mounting bracket and the ground to improve the stability of the mounting bracket and prevent shaking during support.

[0037] Working principle: rotate the extension frame 2 270° counterclockwise until the bottom surface of the extension frame 2 is parallel to the bottom surface of the vertical frame 1, stretch the extension frame 2 to the appropriate position, tighten the locking screw 1 205 to fix the extension frame 2 and the connecting frame 201, place the entire mounting bracket in the corresponding position, the fixing plate 104 fits the supporting surface, and the fixing plate 104 is installed on the supporting surface through the mounting hole through the fastener, remove the locking screw 3 302, pull the oblique bracket 3 and insert the bottom of the oblique bracket 3 into the extension frame 2, and use the locking screw 3 302 to pass through the movable hole 204 to fix the oblique bracket 3, so that the vertical frame 1, the extension frame 2 and the oblique bracket 3 form a triangle, and one side of the vertical frame 1 fits the vertical surface, thereby generating a supporting force for it; remove the locking screw 302, rotate the extension frame 2 clockwise until the bottom surface fits the back of the vertical frame 1, and completely place the oblique bracket 3 into the front of the vertical frame 1, thereby completing the storage of the entire mounting bracket, facilitating the recycling and reuse of the mounting bracket, and improving the portability of the device.
