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 connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0057] This utility model provides a box, such as Figures 1 to 6As shown, it includes a main box body 1, a box cover 2, a box lock 5, a box handle 3, and a linkage locking structure 4; the box cover 2 is fixed to the main box body 1 by the box lock 5; the box handle 3 includes a lower rotating rod 7, a middle linkage rod 8, and a handle connecting rod 9; the lower rotating rod 7 is rotatably disposed on the outer side wall of the main box body 1, the middle linkage rod 8 is slidably disposed within the lower rotating rod 7 and connected to the box cover 2, and the handle connecting rod 9 is slidably connected to the middle linkage rod 8 or the lower rotating rod 7; the linkage locking structure 4 is disposed on the box handle 3, which can change the locking state of the lower rotating rod 7 and the handle connecting rod 9, and change the linkage state between the handle connecting rod 9 and the middle linkage rod 8.

[0058] In this embodiment, as Figures 1 to 5 As shown, during the entire process of opening the box, Figure 1 This is the initial state. Figure 2 The linkage locking structure 4 unlocks the handle connecting rod 9 from the lower rotating rod 7, allowing it to rise. Figure 3 When the linkage locking structure 4 locks the handle connecting rod 9 with the central linkage rod 8, it causes the box cover 2 to rise together. Figure 4 This refers to the state of the box lid 2 when it is raised to a certain position and can be rotated, via the lower rotating rod 7. Figure 5 This is the state after the lid 2 of the box is fully opened and placed inside.

[0059] Specifically, in this embodiment, the connection between the central linkage rod 8 and the box cover 2 is a rotatable connection, such as... Figure 5 It can be seen that the lid 2 can rotate relative to the central linkage rod 8, which facilitates the placement of the lid 2.

[0060] More specifically, in this embodiment, the central linkage rod 8 has a rotating shaft 28, which is inserted into the rotating hole 27 on the side wall of the box cover 2 and is positioned by a fixing pin or other structure to prevent the rotating shaft 28 from coming out of the rotating hole 27.

[0061] In this embodiment, there are two central linkage rods 8 and two lower rotating rods 7, which are respectively set on opposite sides of the main body 1. The handle connecting rod 9 is U-shaped, with its two ends connected to opposite sides of the main body 1, and connected to the two central linkage rods 8 and the lower rotating rods 7 respectively, so that the entire handle 3 is formed into a large U-shape and rotatedly connected to the main body 1.

[0062] In this embodiment, the lid 2 and the main body 1 are two completely independent structures, which are connected by the handle 3 and the lock 5.

[0063] In a preferred embodiment, the linkage locking structure 4 includes a first locking structure and a second locking structure; the first locking structure connects the handle connecting rod 9 and the lower rotating rod 7, and is used to change the connection state between the handle connecting rod 9 and the lower rotating rod 7; the second locking structure connects the handle connecting rod 9 and the middle linkage rod 8, and is used to change the connection state between the handle connecting rod 9 and the middle linkage rod 8.

[0064] In this embodiment, when it is necessary to open the lid 2, i.e., to raise the handle connecting rod 9, the lid 2 and the main body 1 are first unlocked. Then, the first locking structure is activated, separating the handle connecting rod 9 from the lower rotating rod 7, allowing the handle connecting rod 9 to rise and fall freely. Figures 1 to 2 The action process is as follows: When the handle connecting rod 9 rises to a certain height, the second locking structure activates, connecting the handle connecting rod 9 to the middle linkage rod 8, causing the middle linkage rod 8 to rise or fall together within the lower rotating rod 7, thereby causing the box cover 2 to rise or fall. Figures 2 to 3 The action process is as follows: After the lid 2 is fully opened, rotate the lower rotating rod 7 to make the entire box handle 3 swing, so that the lid 2 can be placed on one side of the main box 1.

[0065] When the box is normally placed, the handle 3 is fully retracted, i.e., the handle connecting rod 9 is inserted into the lower rotating rod 7 and locked by the first locking structure. When the box needs to be moved, the first locking structure is opened, and the handle connecting rod 9 is pulled out from the lower rotating rod 7. At this time, because the second locking structure does not connect the handle connecting rod 9 to the middle linkage rod 8, the middle linkage rod 8 does not rise with the handle connecting rod 9, and the lid 2 will not open. At the same time, because the lower rotating rod 7 of the handle 3 is connected to the main box 1, and the middle linkage rod 8 is connected to the lid 2, and the lid 2 is connected to the main box 1 through the box lock 5, a stable structure is formed, so that the handle 3 will not rotate relative to the main box 1, and the box can be moved by the handle 3 under the action of the box wheels 6. When the box needs to be opened, after the handle connecting rod 9 rises or falls to a certain height, the second locking structure is activated, connecting the handle connecting rod 9 to the middle linkage rod 8. Then, lifting the handle connecting rod 9 will drive the lid 2 to rise, thus opening the box.

[0066] In a preferred embodiment, the first locking structure includes a drive button 10, a first linkage structure 11, a first linkage line 13, and a first locking block 24; a locking hole 31 is provided on the lower rotating rod 7, and the first locking block 24 is disposed in the locking hole 31; the drive button 10 is connected to the first linkage structure 11, and the first linkage structure 11 is connected to the first locking block 24 through the first linkage line 13; the drive button 10 can drive the first linkage structure 11 to move the first locking block 24 and disengage it from the locking hole 31.

[0067] In this embodiment, the drive button 10 can drive the first locking structure to move linearly, thereby driving the first linkage line 13 to move axially linearly, bringing the first locking block 24 at the lower end of the first linkage line 13 out of the locking hole 31, thus separating the handle connecting rod 9 from the lower rotating rod 7; when it is necessary to lock the handle connecting rod 9 and the lower rotating rod 7, the drive button 10 moves in the opposite direction, driving the first linkage structure 11, the first linkage line 13 and the first locking block 24 to move in the opposite direction, so that the first locking block 24 enters the locking hole 31.

[0068] In this embodiment, the drive button 10 can be either a push button or a slide button, as long as it can drive the first locking block 24 to move in and out of the locking hole 31.

[0069] In a preferred embodiment, the first locking structure further includes a reset structure 25; one end of the reset structure 25 is fixed and the other end is connected to the first locking block 24, which can drive the first locking block 24 into the locking hole 31 after the drive button 10 is reset.

[0070] In this embodiment, to ensure that the first locking block 24 can enter the locking hole 31, a reset structure 25 is connected to the first locking block 24. The reset structure 25 applies a reverse force to the first locking block 24, causing the first locking block 24 to move in the opposite direction. Thus, after the first locking block 24 is disengaged from the locking hole 31 under the action of the drive button 10, under the action of the reset structure 25, when the drive button 10 is released and the position of the first locking block 24 corresponds to that of the locking hole 31, the first locking block 24 can be driven to re-enter the locking hole 31, thereby achieving a fixed connection between the handle connecting rod 9 and the lower rotating rod 7.

[0071] In this embodiment, the reset structure 25 can be configured as a compression spring, a tension spring, a spring sheet, a torsion spring, etc., as long as it can achieve the reset of the first locking block 24.

[0072] In a preferred embodiment, a positioning rod 26 is provided inside the handle connecting rod, and the first linkage line 13 is provided inside the positioning rod 26.

[0073] In this embodiment, the first linkage line 13 is Y-shaped, that is, one end of the upper end is connected to the first linkage structure 11, and two ends are connected to the two first locking blocks 24. The two first locking blocks 24 are arranged opposite to each other and symmetrically connected in the two locking holes 31 on opposite sides of the lower rotating rod 7.

[0074] Specifically, in this embodiment, after the positioning rod 26 is provided inside the handle connecting rod 9, the two wires at the lower end of the first linkage line 13 can be guided and positioned respectively to avoid entanglement, and at the same time facilitate the installation of the reset structure 25.

[0075] More specifically, in this embodiment, the reset structure 25 is a compression spring. The compression spring is sleeved on the first linkage line 13, with one end abutting against the end of the positioning rod 26 and the other end abutting against the first locking block 24. When the drive button 10 moves the first locking block 24, it compresses the compression spring. When the drive button 10 is released and the first locking block 24 corresponds to the locking hole 31, the compression spring resets and sends the first locking block 24 into the locking hole 31, thereby locking the handle connecting rod 9 and the lower rotating rod 7.

[0076] In a preferred embodiment, such as Figure 7 As shown, the first linkage structure 11 includes a linkage base 15, an active drive block 17, and a passive sliding block 16. The active drive block 17 is fixedly mounted on the drive button 10, and the passive sliding block 16 is slidably mounted on the linkage base 15. The other end of the passive sliding block 16 abuts against the active drive block 17. A linkage groove is provided on the passive sliding block 16, and one end of the passive sliding block 16 is connected to the first linkage line 13. The side wall of the linkage groove away from the first linkage line 13 forms a set angle with the sliding direction of the passive sliding block 16, so that the opening width of the linkage groove is greater than the bottom width. The active drive block 17 abuts against the side wall of the linkage groove away from the first linkage line 13, and the moving direction of the active drive block 17 is perpendicular to the moving direction of the passive sliding block 16.

[0077] In this embodiment, the active drive block 17 is fixedly mounted on the drive button 10 and can move synchronously with the drive button 10, driving the passive sliding block 16 to move linearly.

[0078] Specifically, in this embodiment, the linkage base 15 is fixed, and the passive sliding block 16 slides linearly on the linkage base 15 under the action of the active driving block 17, driving the first linkage line 13 to move axially, and pulling the first locking block 24 at the other end of the first linkage line 13 to move.

[0079] More specifically, in this embodiment, the active sliding block is wedge-shaped, and the passive sliding block 16 is formed at the end away from the first linkage line 13 by the setting of the linkage groove, which is a wedge-shaped corresponding to the active sliding block. Thus, the driving sliding block can be driven by the driving button 10 to move back and forth towards the linkage base 15, thereby driving the passive sliding block 16 to move. Under the action of the reset structure 25, the passive sliding block 16 moves back and forth.

[0080] In a preferred embodiment, the second locking structure includes an upper driving member, a middle connecting member 21, a lower locking member, a second linkage line 14, and a locking linkage rod 32; the upper driving member is connected to the middle connecting member 21 via the second linkage line 14, and the middle connecting member 21 is connected to the lower locking member via the locking linkage rod 32, which can drive the lower locking member to move and lock the box handle 3 and the box cover 2.

[0081] In this embodiment, the second locking structure is divided into three parts: an upper driving member, a middle connecting member 21, and a lower locking member. The upper driving member is connected to the middle connecting member 21 via the second linkage line 14, and the middle connecting member 21 is connected to the lower locking member via the locking linkage rod 32.

[0082] Specifically, in this embodiment, the upper driving member drives the second linkage line 14 to move linearly in the axial direction, and the middle connecting member 21 converts the linear movement into rotation, thereby driving the locking linkage rod 32 to rotate, and finally driving the lower locking member to rotate, so as to realize the positioning connection between the lower locking member and the middle linkage rod 8.

[0083] In a preferred embodiment, such as Figure 7 As shown, the upper driving component includes a hollow driving shaft 12 and a connecting end 19; a portion of the first locking structure is disposed within the hollow driving shaft 12; the connecting end 19 is disposed at the end of the hollow driving shaft 12; a first spiral groove 20 is provided on the outer side wall of the connecting end 19; one end of the second linkage line 14 has a first connecting block 18, the first connecting block 18 is slidably disposed within the first spiral groove 20, and can move linearly along the hollow driving shaft 12 when the connecting end 19 rotates.

[0084] In this embodiment, the hollow drive shaft 12 has a hollow structure with a cavity. The first linkage structure 11 is disposed in the cavity. The side wall of the hollow drive shaft 12 has a button hole, and the drive button 10 is disposed in the button hole.

[0085] This setup can save a lot of space and improve space utilization.

[0086] In this embodiment, the linkage base 15 can be integrally set with the hollow drive shaft 12, or it can be fixedly connected together in other ways, or the linkage base 15 can be omitted and the passive sliding block 16 can slide directly inside the hollow drive shaft 12. In other words, as long as the first linkage structure 11 can be set inside the hollow drive shaft 12, it is acceptable.

[0087] In this embodiment, the rotation of the hollow drive shaft 12 causes the connecting end 19 to rotate. Since the connecting end 19 has a first spiral groove 20, the first connecting block 18 slides in the first spiral groove 20 while the hollow drive shaft 12 is rotating, thereby driving the first linkage line 13 to move linearly.

[0088] In a preferred embodiment, such as Figure 8 As shown, a second spiral groove 22 is provided on the outer side wall of the middle connector 21, and a second connecting block 23 is provided at the other end of the second linkage line 14. The second connecting block 23 is slidably disposed in the second spiral groove 22, and can drive the middle connector 21 and the locking linkage rod 32 disposed on the middle connector 21 to rotate when the second linkage line 14 moves axially.

[0089] In this embodiment, the second spiral groove 22 is provided so that when the second linkage line 14 pulls the middle connector 21 through the second connecting block 23, it drives the middle connector 21 to rotate instead of move axially, thereby causing the locking connecting rod to rotate as well, thus realizing the function of converting linear displacement into rotation.

[0090] In a preferred embodiment, such as Figure 9 and Figure 10 As shown, the lower locking component includes a second locking block 29 and a locking spring 30; the second locking block 29 is fixedly disposed inside the middle linkage rod 8; a sliding groove is provided on the second locking block 29, the locking spring 30 is disposed in the sliding groove, and the locking linkage rod 32 is slidably disposed in the sliding groove; a plurality of locking grooves 33 are provided on the side wall of the locking linkage rod 32, and when the locking linkage rod 32 rotates, the state of the locking spring 30 moving in and out of the locking groove 33 can be changed.

[0091] In this embodiment, the locking linkage rod 32 rotates to allow the locking spring 30 to slide in or out of the locking groove 33 on the locking linkage rod 32. Thus, through the cooperation between the locking spring 30 and the locking groove 33, the locking connecting rod provided on the handle connecting rod 9 is connected to the second locking block 29 provided on the middle linkage rod 8. This allows the middle linkage rod 8 to be raised or lowered by the raising or lowering of the handle connecting rod 9.

[0092] Specifically, in this embodiment, a reset structure is provided inside or at the lower end of the locking linkage rod 32. The direction of the force applied by the reset structure is opposite to the direction of the second spiral groove 22. When the locking linkage rod 32 rotates under the action of the second spiral groove 22, the reset structure applies a reverse force so that the locking linkage rod 32 can be reset after the hollow drive shaft 12 is reset, thereby separating the locking spring 30 from the locking groove 33 and realizing the separation of the handle connecting rod 9 from the middle linkage rod 8.

[0093] More specifically, in this embodiment, the reset structure is a torsion spring.

[0094] In a preferred embodiment, the lower end of the lower rotating rod 7 has an end cap 36; the main housing 1 has a positioning shaft 34 and a positioning cylinder plate 35, which are coaxially arranged; the end cap 36 covers the positioning cylinder plate 35 and is rotatably connected to the positioning cylinder plate 35; the positioning cylinder plate 35 has a notch 37, and the lower end of the middle linkage rod 8 passes through the notch 37 and inserts into the interior of the positioning cylinder plate 35.

[0095] In a preferred embodiment, the lower end of the central linkage rod 8 has a rotating groove 38, which abuts against the side wall of the positioning shaft 34.

[0096] In this embodiment, the rotational connection between the positioning cylinder plate 35 and the lower rotating rod 7 not only achieves the purpose of rotational connection, but also protects the components inside the lower rotating rod 7, such as the central linkage rod 8 and the handle connecting rod 9, reducing interference from external factors and increasing the safety and service life of use.

[0097] Specifically, in this embodiment, after adding a notch 37 to the positioning cylinder plate 35, the central linkage rod 8 is inserted into the notch 37, which can increase the positioning stability of the handle.

[0098] More specifically, in this embodiment, the lower end of the rotating groove 38 of the middle linkage rod 8 abuts against the positioning shaft 34, so that the middle linkage rod 8 and the positioning shaft 34 can only be rotated. However, since the middle linkage rod 8 is set in the notch groove 37, the positioning middle linkage rod 8 cannot be rotated.

[0099] When rotation is required, the central linkage rod 8 moves upward and can disengage from the notch 37 before the handle of the housing can be rotated, thereby increasing the positioning stability of the handle of the housing.

[0100] The beneficial effects of this utility model are as follows:

[0101] By setting the handle 3 of the box as a three-layer sleeve structure, the outermost layer is rotatably connected to the main box 1, and the innermost layer is fixedly connected to the box cover 2. The state of the handle 3 of the box is changed by the linkage locking structure 4, so that the handle connecting rod 9 of the handle 3 can slide relative to the lower rotating rod 7 to achieve extension and retraction. The state change of the middle linkage rod 8 and the handle connecting rod 9 can drive the box cover 2 to rise during the process of the handle connecting rod 9 rising. After the box cover 2 rises to a certain extent, it can be rotated to place the box cover 2 on one side of the main box 1, so that the box can be opened with one hand.
