DETAILED DESCRIPTION

[0047] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be described in more detail below in conjunction with the accompanying drawings in the preferred embodiments of the present invention.

[0048] like Figure 1 , Figure 4 and Fig.11 As shown, an embodiment of the utility model provides a display unit, including a box body 1, which includes a side wall 11; a mounting assembly 2, connected to the side wall 11; a handle 3, rotatably connected to the mounting assembly 2, and the handle 3 is used to rotate relative to the mounting assembly 2 between a first position and a second position; in the first position, the handle 3 is unfolded relative to the side wall 11; in the second position, the handle 3 is folded relative to the side wall 11.

[0049] It is understandable that the box body 1 may include two oppositely arranged side walls 11 , and a handle 3 is installed on each side wall 11 , so that the user can lift the box body 1 by the handles 3 on both sides of the box body 1 .

[0050] In the display unit provided by the embodiment of the utility model, a mounting assembly 2 is connected to the side wall 11 of the box body 1, and a handle 3 is rotatably connected to the mounting assembly 2. The handle 3 can be rotated between a first position and a second position relative to the mounting assembly 2. In the first position, the handle 3 can be unfolded relative to the side wall 11; in the second position, the handle 3 can be folded on the side wall 11. When it is necessary to carry or assemble the display unit, the user can rotate the handle 3 to the first position so that the handle 3 is unfolded relative to the side wall 11, so that the display unit can be carried or assemble by lifting the handle 3, thereby reducing the difficulty of carrying or assembling the display unit and improving work efficiency. When it is not necessary to carry or assemble the display unit, the user can rotate the handle 3 to the second position so that the handle 3 is folded on the side wall 11, which is more convenient to use.

[0051] In addition, in the display unit provided by the embodiment of the utility model, the handle 3 is rotatably connected to the mounting assembly 2 instead of being directly connected to the side wall 11 of the box body 1. In this way, when the handle 3 is pulled, direct force on the box body 1 can be avoided, thereby reducing the force on the box body 1 and extending the service life of the box body 1.

[0052] In some embodiments, see Figure 2 , Figure 3 , Figures 5 to 7 The mounting assembly 2 may include a first fixing member 21, a second fixing member 22 and a connecting member 23, the first fixing member 21 is connected to one end of the connecting member 23, the other end of the connecting member 23 passes through the side wall 11 and is connected to the second fixing member 22; at least part of the first fixing member 21 is located on the outer side of the side wall 11; the second fixing member 22 is located on the inner side of the side wall 11; the handle 3 is rotatably connected to the first fixing member 21.

[0053] When the handle 3 is lifted, the first fixing member 21 transfers part of the stress it is subjected to to the inner side surface of the side wall 11 and the second fixing member 22 through the connecting member 23, thereby reducing the stress in the contact area between the handle 3, the first fixing member 21 and the outer side surface of the box body 1, thereby dispersing the stress applied to the handle 3, the mounting assembly 2 and the box body 1 to avoid generating a large contact stress between the handle 3, the mounting assembly 2 and the box body 1, thereby increasing the service life of the handle 3, the mounting assembly 2 and the box body 1.

[0054] The connecting member 23 may have various structural forms. For example, the connecting member 23 may be a fastener such as a bolt.

[0055] In some embodiments, see Figure 1 , Figure 3 , Figure 4 , Figure 6 and Fig. 9The first fixing member 21 may be provided with a first limiting portion 211 and a second limiting portion 212 ; in the first position, the handle 3 abuts against the first limiting portion 211 ; in the second position, the handle 3 abuts against the second limiting portion 212 .

[0056] During the process of rotating the handle 3 to switch its working state, when the handle 3 is rotated to abut against the first limit portion 211, the handle 3 can be in the first position and unfolded relative to the side wall 11. When the handle 3 is rotated to abut against the second limit portion 212, the handle 3 can be in the second position and folded on the side wall 11, which is more convenient to operate.

[0057] The first limiting portion 211 and the second limiting portion 212 may have various structural forms, as long as the handle 3 can be limited to the first position and the second position respectively. For example, the first limiting portion 211 and the second limiting portion 212 may be baffles disposed on the first fixing member 21, and the baffles are correspondingly disposed at the first position or the second position.

[0058] For ease of operation, in some embodiments, see Figure 8 and Fig. 9 A mounting groove 213 may be provided on the first fixing member 21, and the mounting groove 213 includes a first retaining wall, a second retaining wall and two oppositely arranged groove side walls 214, the first retaining wall is connected to one end of the two groove side walls 214, and the second retaining wall is connected to the other end of the two groove side walls 214; one end of the handle 3 is rotatably connected between the two groove side walls 214 through a rotating shaft, and the mounting groove 213 is used to provide a movable space for the handle 3 to rotate between the first position and the second position; in the first position, the handle 3 abuts against the first retaining wall; in the second position, the handle 3 abuts against the second retaining wall; the first retaining wall may be a first limiting portion 211; the second retaining wall may be a second limiting portion 212.

[0059] Among them, the handle 3 can rotate in the installation groove 213. When the handle 3 is rotated to abut against the first retaining wall, the handle 3 can be located at the first position. When the handle 3 is rotated to abut against the second retaining wall, the handle 3 can be located at the second position. In this way, the first retaining wall can be used as the first limiting part 211 and the second retaining wall can be used as the third limiting part. The structure is simple and reliable to use.

[0060] In some embodiments, the mounting assembly 2 may further include a third limiting portion, which is disposed on the groove side wall 214 or the handle 3 and is used to limit the handle 3 from rotating from the second position to the first position.

[0061] The third limiter can limit the handle 3 from rotating from the second position to the first position. In other words, the third limiter can keep the handle 3 stably in the second position, preventing the handle 3 from leaving the second position when there is no need to lift the handle 3, making it more convenient to use.

[0062] It can be understood that when an external force is applied to the handle 3 toward the second position, the handle 3 can break free from the limiting effect of the third limiting portion and rotate to the first position, so that the box body 1 can be lifted by the handle 3.

[0063] The third limiting portion may have various structural forms, as long as it can limit the handle 3 from rotating toward the first position at the second position.

[0064] In some embodiments, see Fig. 9 and Fig.10 , and combined with Figure 4 , Figure 5 and Figure 6 The third limiting portion may include a limiting protrusion 2141; the limiting protrusion 2141 may be arranged on the groove side wall 214, and a card slot 31 is opened at the end of the handle 3; or, the limiting protrusion 2141 is arranged on the handle 3, and a card slot 31 is opened on the groove side wall 214; in the second position, the limiting protrusion 2141 is engaged in the card slot 31; in the first position, the limiting protrusion 2141 is disengaged from the card slot 31.

[0065] When the handle 3 switches from the second position to the first position, the limiting protrusion 2141 can slide out of the slot 31 along the outer wall of the handle 3 or the groove side wall 214 until the handle 3 is rotated to the first position; when the handle 3 switches from the first position to the second position, the limiting protrusion 2141 can slide into the slot 31 along the outer wall of the handle 3 or the groove side wall 214 until the handle 3 is rotated to the second position.

[0066] For ease of use, a limiting protrusion 2141 may be provided on the groove side wall 214, and a clamping groove 31 may be provided at the end of the handle 3. Moreover, at least one groove side wall 214 may be provided with a limiting protrusion 2141, and at least one clamping groove 31 may be provided on the handle 3. In the second position, the limiting protrusion 2141 is clamped in the corresponding clamping groove 31. Moreover, in order to facilitate the installation of the limiting protrusion 2141 on the groove side wall 214, the mounting assembly 2 may further include a mounting rod, the limiting protrusion 2141 is provided on the end surface of the mounting rod, a mounting through hole is provided on the groove side wall 214, the mounting rod is inserted into the mounting through hole, and the limiting protrusion 2141 extends into the mounting groove 213.

[0067] In order to facilitate the limiting protrusion 2141 to slide into or out of the slot 31 , in some embodiments, the surface of the limiting protrusion 2141 may be an arc-shaped surface.

[0068] In addition, the handle 3 may be a cylindrical tube structure, and its outer surface is arc-shaped, which can also facilitate the limiting protrusion 2141 to slide into the slot 31. Moreover, the slot 31 may be a U-shaped slot opened on the end surface of the handle 3 and passing through the inner and outer surfaces of the handle 3.

[0069] In order to facilitate the limiting protrusion 2141 to slide into or out of the card slot 31, in some embodiments, see Fig.10 The handle 3 or the groove side wall 214 may be provided with a guide surface 32, which extends around the circumference of the slot 31 and is inclined toward the slot 31. The limiting protrusion 2141 can slide into or out of the slot 31 more smoothly under the action of the guide surface 32.

[0070] To further facilitate operation, in some other embodiments, the limiting protrusion 2141 can be retractably arranged on the groove side wall 214 by an elastic member such as a spring, so that when the limiting protrusion 2141 slides along the outer wall of the handle 3, the limiting protrusion 2141 can be retracted, thereby reducing the friction between the limiting protrusion 2141 and the handle 3, thereby reducing the external force required to switch the working position of the handle 3, and making the operation more convenient.

[0071] In some embodiments, see Figure 1 and Figure 4 , a receiving cavity 111 may be provided on the side wall 11 ; the first fixing member 21 is disposed in the receiving cavity 111 ; in the first position, the handle 3 is separated from the receiving cavity 111 ; in the second position, the handle 3 is received in the receiving cavity 111 .

[0072] When the handle 3 is in the second position, it can be stored in the accommodating cavity 111, so that the handle 3 can be prevented from protruding from the side wall 11 of the box body 1, which is convenient for splicing between display units and transporting the display units. At the same time, it is also convenient for the user to extend his hand into the accommodating cavity 111 to apply force to the handle 3 to switch the working position of the handle 3.

[0073] In some embodiments, see Figure 1 , Figure 3 , Figure 8 and Fig. 9 The side wall 11 of the box body 1 may be a hollow structure, and the inner space of the side wall 11 is connected to the accommodating cavity 111; the first fixing member 21 may include a connecting end 215, and the connecting end 215 extends into the inner space of the side wall 11 and is connected to the connecting member 23. Thus, the connecting member 23 is hidden inside the side wall 11, which can not only improve the connection strength between the mounting assembly 2 and the side wall 11, but also improve the overall aesthetics of the display unit.

[0074] An embodiment of the utility model further provides a display screen, comprising the aforementioned display unit.

[0075] The display screen provided in the embodiment of the utility model includes a display unit, and therefore, the display screen has all the beneficial effects of the display unit, which will not be described in detail here.
