They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0024] like Figures 1 to 7 As shown, an embodiment of the device for quickly switching the working mode of the roller box according to the present invention includes: a fixed shaft 1, with locking devices 2 provided at both ends of the fixed shaft, and a working housing 3 rotatably provided outside the fixed shaft. The working housing includes at least: a first working surface 31 for installing roller box stop blocks; a second working surface 32, which is set at 90 degrees or less than 90 degrees with the first working surface and is used as part of a slide rail or for installing a guide rail or slide rail block for the roller box to slide; and a locking device 5 is provided on the side wall of the working housing corresponding to the first working surface or the second working surface, which is used to lock the first working surface of the working housing in the working position or lock the second working surface in the working position.

[0025] As shown in the figure, the fixed shaft and the U-shaped locking device are connected to each other by bolts, and a hole is drilled between the fixed shaft and the pin and the pin 12 is inserted to make the locking device stable and reduce vibration during operation.

[0026] As shown in the figure, this device uses two working surfaces and one operating surface. The working mode is selected by a locking device and the working mode can be quickly switched, eliminating the cumbersome disassembly and assembly of the fixed method.

[0027] The locking device 5 includes: a locking block groove provided on the side wall of the working housing, a locking block 51 slidably disposed in the locking block groove, and a locking groove cover 52 provided on the outer surface of the side wall of the working housing corresponding to the locking block groove; it also includes one or more connecting rods 53, one end of the connecting rod is disposed on the locking block, the other end of the connecting rod passes through a through hole on the locking groove cover and is located outside the locking groove cover, and a handle 54 is provided on the end of the connecting rod located outside the locking groove cover; a spring 55 is sleeved on the connecting rod between the locking groove cover and the locking block;

[0028] The fixed shaft has grooves that are adapted to the locking block at positions corresponding to the first working surface and the second working surface.

[0029] Furthermore, the depth of the groove is less than the length of the locking block in the direction of insertion.

[0030] like Figure 4 As shown, the locking device uses a spring to insert the locking block into the slot to select the mode. When the mode is selected, the working surface can be accurately aligned, and the working surface can be prevented from flipping due to vibration. The handle also makes it easy to change the mode by hand.

[0031] like Figures 5 to 7 As shown, an optional embodiment of the roller box slide seat of the present invention includes at least a base, on which a slide is provided, and a fixing stop device is provided at one end of the slide; a recess is provided on the slide at a predetermined distance from the fixing stop device, and the aforementioned device for quickly switching the working mode of the roller box is provided in the recess along the length of the slide; wherein, the locking devices at both ends of the fixing shaft are fixed in the recess.

[0032] Figure 5 In the middle, the first working face is equipped with a roller box stop block; at this time, the roller box stop block is located in the working position and cooperates with the fixed stop device at the end of the slide to fix the roller box;

[0033] When switching is required, pull the handle to disengage the locking block from the groove on the fixed shaft and rotate it 90 degrees so that the second working surface is in the working position. The second working surface is equipped with a slider that matches the slide rail, which facilitates the quick replacement of the roller box from the slide rail.

[0034] The application has been described in detail with reference to the drawings, but the application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit and scope of the application.
