[0008] The driving component includes a driving shaft, which is rotatably disposed in the first receiving cavity. When the driving shaft rotates, it can drive the locking tongue to move along the first direction through the transmission component.

[0009] In some embodiments, the driving component further includes a driving handle, and the second splicing end has a first shaft hole communicating with the first receiving cavity. The first shaft hole allows the driving shaft to pass through or allows the driving end of the driving handle to pass through, so that the driving end of the driving handle is connected to the driving shaft for driving the driving shaft to rotate.

[0010] In some embodiments, the transmission element includes a gear and two racks, the gear being mounted on the drive shaft, and the two racks meshing with the gear and located on opposite sides of the gear.

[0011] In some embodiments, at least one ball screw is provided in the first receiving cavity, and at least one ball screw positioning hole is provided on the rack. When the axis of the ball screw coincides with the axis of the ball screw positioning hole, the steel ball of the ball screw can partially fall into the ball screw positioning hole. When the axis of the ball screw positioning hole does not coincide with the axis of the ball screw, the steel ball of the ball screw can disengage from the ball screw positioning hole.

[0012] In some embodiments, the rack includes a toothed segment, a connecting segment, and a moving segment connected in sequence.

The included angle between the connecting segment and the toothed segment is an obtuse angle, and the included angle between the connecting segment and the moving segment is an obtuse angle.

[0013] In some embodiments, the linkage assembly further includes a housing, within which a first mounting portion is provided for mounting the gear. The first mounting portion is provided with a second shaft hole, the axis of which coincides with the axis of the first shaft hole. The second shaft hole allows the drive shaft to pass through or the drive end of the drive handle to pass through.

[0014] The housing also has two second mounting parts, each of which is used to mount one of the racks.

[0015] In some embodiments, at least one positioning post is provided on the outer shell, and a positioning hole corresponding to the position of the positioning post is provided on the side wall of the first receiving cavity, wherein the axis of the positioning post coincides with the axis of the positioning hole at the corresponding position.

[0016] In some embodiments, the housing has a through hole at the end in the first direction, through hole for the locking tongue to pass through, the housing has a limiting step at the end in the first direction, the moving section of the rack has a limiting part, and when the locking tongue is inserted into the lock hole in the first direction, the limiting part abuts against the limiting step.

[0017] In some embodiments, the housing is provided with a guide post corresponding to the moving segment, the moving segment is provided with a guide groove, the guide groove is sleeved on the guide post and can move relative to the guide post along the first direction.

[0018] In some embodiments, the locking tongue includes a main body segment, an arc-shaped connecting segment, and a guide segment connected in sequence. The main body segment is connected to the driving member, and the cross-sectional area of ​​the arc-shaped connecting segment gradually decreases axially from the end of the main body segment to the end of the guide segment.

[0019] In some embodiments, the axis of the latch is parallel to and not collinear with the axis of the lock hole.

[0020] In some embodiments, a first copper sleeve is fitted inside the keyhole.

[0021] A second aspect of this application provides a splicing display device, including at least two display cabinets and a splicing device as described in the second aspect, wherein two adjacent display cabinets are spliced ​​together by the splicing device.

[0022] The splicing device of this application includes at least two locking pin assemblies and a linkage assembly. The locking pin assemblies are installed at the first splicing end of the display cabinet, and the linkage assembly is installed at the second splicing end of the display cabinet, with the second splicing end opposite to the first splicing end. The linkage assembly includes at least two locking tongues and a driving member connected to the locking tongues. When two adjacent display cabinets are spliced ​​together through the first and second splicing ends, the driving member drives the locking tongues to move along a first direction, causing the locking tongues to insert into the corresponding lock holes of the adjacent display cabinets, or causing the locking tongues to disengage from the corresponding lock holes of the adjacent display cabinets. In other words, only the driving member needs to be operated to lock and unlock the two adjacent display cabinets, thus simplifying the locking and unlocking operations and improving the splicing and installation efficiency of the display cabinets.

[0045] In video wall display systems, display modules are fixed to display cabinets, and adjacent display cabinets are connected to each other via a splicing device to achieve a spliced ​​display. Currently, the locking and unlocking operations of splicing devices are cumbersome, resulting in low installation efficiency.

[0046] In view of this, embodiments of this application provide a splicing device and a splicing display equipment, which can simplify locking and unlocking operations and improve installation efficiency.

[0047] In a first aspect, embodiments of this application provide a splicing device for connecting two adjacent display cabinets. The display cabinets are used in a splicing display device, which includes multiple display cabinets and multiple display modules spliced ​​together. Each display module includes a display substrate and a driving circuit board electrically connected to the display substrate. The display cabinets support the display modules. For example, the display cabinet includes a bottom wall and side walls connected to the bottom wall, forming a receiving space between the bottom wall and the side walls. The display substrate is supported on the side walls, and the driving circuit board is located in the receiving space.

[0048] Figure 1This is a schematic application diagram of a splicing device provided in an embodiment of this application. The splicing device of this embodiment includes at least two locking pin assemblies 10 and a linkage assembly 20. The locking pin assembly 10 is used to be installed at the first splicing end 31 of the display cabinet 30. The linkage assembly 20 is used to be installed at the second splicing end 32 of the display cabinet 30.

[0049] See also Figure 1 The locking pin assembly 10 has a locking hole 101. The linkage assembly 20 includes at least two locking tongues 201 and a driving member 202 connected to the locking tongues 201. The driving member 202 can drive the locking tongues 201 to move along a first direction. When two adjacent display cabinets 30 are spliced ​​together, the two display cabinets 30 move relative to each other so that the splicing ends of the two display cabinets 30 contact, thereby splicing the two display cabinets 30 together. In this embodiment, the first direction can be a direction perpendicular to the splicing movement direction of the display cabinets 30.

[0050] Figure 1 The first splicing end 31 is located at the top of the display cabinet 30, and the second splicing end 32 is located at the bottom of the display cabinet 30. The locking pin assembly 10 is installed at the top of the display cabinet 30, and the linkage assembly 20 is installed at the bottom of the display cabinet 30. A locking pin assembly mounting hole can be provided on the end face of the first splicing end 31. The locking pin assembly 10 is placed in the locking pin assembly mounting hole, and the locking pin assembly 10 is detachably connected to the display cabinet 30 by mounting screws.

[0051] The portion of the locking pin assembly 10 that is housed within the mounting hole can be cylindrical, while the portion protruding from the mounting hole can be flat. A locking hole 101 is located at the end of the locking pin assembly 10 that protrudes from the mounting hole.

[0052] The axis of the mounting screw can be perpendicular to the axis of the locking pin assembly 10, and the mounting screw passes through the locking pin assembly 10 and the mounting hole of the locking pin assembly. The length of the mounting screw can be two-thirds of the thickness of the display cabinet 30. The top center of the display cabinet 30 is provided with grooves on both sides, and the depth of the grooves can be one-sixth of the top wall thickness of the display cabinet 30, which can reduce the weight of the entire display cabinet 30 accordingly.

[0053] The upper display cabinet 30 moves relative to the lower display cabinet 30 along the height direction Z of the display cabinet 30 until the second splicing end 32 of the upper display cabinet 30 contacts the first splicing end 31 of the lower display cabinet 30. At this time, the first direction is perpendicular to the height direction Z of the display cabinet 30. For example, the first direction can be the length direction Y of the display cabinet 30, or the width direction X of the display cabinet 30.

[0054] When two adjacent display cabinets 30 are spliced ​​together through the first splicing end 31 and the second splicing end 32, the driving member 202 can drive the locking tongue member 201 to move along the first direction, so that the locking tongue member 201 is inserted into the corresponding lock hole 101 of the adjacent display cabinet 30, or the locking tongue member 201 is disengaged from the corresponding lock hole 101 of the adjacent display cabinet 30.

[0055] A first copper sleeve 102 can be fitted inside the lock hole 101 of the locking pin assembly 10, and the first copper sleeve 102 fits tightly with the lock hole 101. The lock hole 101 can be a round hole, and the latch 201 can be cylindrical. The first copper sleeve 102 allows the latch 201 to be inserted into the lock hole 101 more smoothly.

[0056] Two adjacent display cabinets 30 have two connection states: a loose state and a locked state. When the two adjacent display cabinets 30 are in the loose state, the drive member 202 does not drive the locking tongue 201 to insert into the corresponding lock hole 101 of the adjacent display cabinet 30. If it is necessary to change the connection state of the two adjacent display cabinets 30, the drive member 202 can drive the locking tongue 201 to move along the first direction, so that the locking tongue 201 is inserted into the corresponding lock hole 101 of the adjacent display cabinet 30, and the connection state of the two adjacent display cabinets 30 changes from the loose state to the locked state.

[0057] If it is necessary to change the connection state of two adjacent display cabinets 30 from the locked state to the unlocked state, the locking tongue 201 can be moved along the first direction by the driving component 202 so that the locking tongue 201 disengages from the lock hole 101 at the corresponding position of the adjacent display cabinet 30.

[0058] Therefore, by setting up the splicing device of this application embodiment, two display cabinets can be easily spliced ​​together, thus simplifying the locking and unlocking operations and improving the installation efficiency of the splicing display device. Furthermore, the splicing device of this application not only completes the locking or unlocking operation in just one step, but also utilizes the combination of the locking pin assembly 10 inserted into the fixing hole 322 and the locking tongue 201 inserted into the locking hole 101 to achieve the installation positioning of two adjacent display cabinets 30, further improving the installation efficiency of the splicing display device.

[0059] In some embodiments, the second splicing end 32 of the display cabinet 30 is provided with a first receiving cavity 321 for accommodating the locking tongue 201, and the second splicing end 32 is also provided with at least two fixing holes 322 communicating with the first receiving cavity 321, wherein the axis of the fixing hole 322 coincides with the axis of the corresponding locking pin assembly 10, so that the locking pin assembly 10 of the adjacent display cabinet 30 passes through the fixing hole 322 and is placed in the first receiving cavity 321. When two adjacent display cabinets 30 are spliced, at least two locking pin assemblies 10 are inserted into the corresponding fixing holes 322, which can facilitate the positioning of the splicing position without the need for manual alignment of the two display cabinets 30, thereby improving installation efficiency.

[0060] like Figure 1 As shown, the first receiving cavity 321 is located on the non-display side of the display panel. When two adjacent display cabinets 30 are spliced ​​together, two locking pin assemblies 10 are provided on the top (first splicing end 31) of the lower display cabinet 30, and the first receiving cavity 321 is provided on the bottom (second splicing end 32) of the upper display cabinet 30. The locking tongue 201 is disposed inside the first receiving cavity 321, and the driving member 202 can also be disposed inside the first receiving cavity 321. By placing the locking device inside the first receiving cavity 321, the splicing width of the two adjacent display cabinets 30 can be reduced. To facilitate the display of the components in the first receiving cavity 321, Figure 1 The components housed inside the first receiving cavity 321 are displayed outside the first receiving cavity 321.

[0061] The first receiving cavity 321 may also have an opening, the direction of which may be perpendicular to the splicing and moving direction of the two adjacent display cabinets 30. The opening allows components such as the locking tongue 201 to be placed inside the first receiving cavity 321, and also allows components such as the locking tongue 201 to be removed from the first receiving cavity 321, facilitating maintenance of these components. For example, Figure 1 The opening direction of the first receiving cavity 321 is parallel to the width direction X of the display cabinet 30. When the two display cabinets 30 are locked or released, the opening of the first receiving cavity 321 can also be used to facilitate observation of the driving state of the driving member 202, and at the same time facilitate observation of the positional relationship between the locking tongue member 201 and the lock hole 101.

[0062] See also Figure 1 The second splicing end 32 has two fixing holes 322, the axes of which coincide with the axes of the corresponding locking pin assemblies 10. When two adjacent display cabinets 30 are spliced, the locking pin assemblies 10 can be inserted into the corresponding fixing holes 322, and thus the locking pin assemblies 10 are placed into the first receiving cavity 321 through the corresponding fixing holes 322. This allows the locking tongue 201 to be inserted into the corresponding locking hole 101.

[0063] In some implementations, such as Figure 1 As shown, the linkage assembly 20 also includes at least two transmission members 203 connected to the drive member 202. The transmission members 203 are also placed within the first receiving cavity 321, and the locking tongue member 201 is located at the end of the transmission member 203 away from the drive member 202. The drive member 202 includes a drive shaft 2021. The drive shaft 2021 is rotatably disposed in the first receiving cavity 321. When the drive shaft 2021 rotates, it can drive the locking tongue member 201 to move along a first direction via the transmission members 203. Thus, by utilizing the rotation of a single drive shaft 2021, the transmission member 203 can be moved, and the locking tongue member 201 can be moved along the first direction via the transmission member 203, thereby achieving both convenient operation and a simplified structure of the splicing device.

[0064] In some implementations, such as Figure 1 As shown, the driving component 202 may further include a driving handle 2022. The second splicing end 32 has a first shaft hole 323 communicating with the first receiving cavity 321. The first shaft hole 323 allows the driving shaft 2021 to pass through or allows the driving end of the driving handle 2022 to pass through, so that the driving end of the driving handle 2022 is connected to the driving shaft 2021. The driving handle 2022 can drive the driving shaft 2021 to rotate, thereby driving the transmission component 203 to move, and further driving the locking tongue component 201 to move along the first direction. The driving handle 2022 has a driving end and a handle end, and the axis of the driving end of the driving handle 2022 may coincide with the axis of the driving shaft 2021. The position of the handle end of the driving handle 2022 changes with the locked or unlocked state. For example, the axis of the handle end of the driving handle 2022 may be parallel to the first direction or form an angle with the first direction.

[0065] It should be noted that the drive handle 2022 can be fixedly connected to the drive shaft 2021 or detachably connected. When the drive handle 2022 is detachably connected to the drive shaft 2021, after two adjacent display cabinets 30 are locked, the drive handle 2022 can be removed from the display cabinet 30 and used for splicing and locking operations of other display cabinets 30. If it is necessary to loosen two adjacent display cabinets 30, the drive handle 2022 can be reconnected to the drive shaft 2021, and then the loosening operation of the two adjacent display cabinets 30 can be performed.

[0066] Figure 2 This is a schematic perspective view of a drive handle provided in an embodiment of this application. Figure 2As shown, the drive handle 2022 can have a handheld end and a drive end. The axis of the handheld end of the drive handle 2022 can be perpendicular to the axis of the drive end. This allows the rotational motion of the handheld end around the drive shaft 2021 to be converted into the rotational motion of the drive end. The handheld end and the drive end of the drive handle 2022 can be connected by an arc. The end of the drive end away from the handheld end is provided with a blind hole whose shape matches the shape of the drive shaft 2021.

[0067] The drive shaft 2021 can be a hexagonal prism made of a rigid material. For example... Figure 2 As shown, a hexagonal prism-shaped blind hole can be provided at the end of the drive end away from the handheld end. One end of the drive shaft 2021 can be inserted into the hexagonal prism-shaped blind hole, so that the drive handle 2022 can be fixedly connected to the drive shaft 2021, so that the drive handle 2022 can drive the transmission component 203 to move when it rotates.

[0068] Figure 3 This is a schematic installation structure diagram of a transmission component and a housing provided in an embodiment of this application. In some embodiments, such as Figure 3 As shown, the transmission component 203 includes a gear 2031 and two racks 2032, wherein the gear 2031 is sleeved on the drive shaft 2021, and the two racks 2032 are located on opposite sides of the gear 2031 and mesh with the gear 2031 respectively.

[0069] In other words, two racks 2032 are respectively disposed on both sides of the gear 2031, and the gear 2031 is connected to the drive shaft 2021. Therefore, when the drive shaft 2021 rotates, it can drive the gear 2031 to rotate. Since the two racks 2032 mesh with the gear 2031, when the gear 2031 rotates, it can drive the two racks 2032 to move in opposite directions or towards each other in the first direction on both sides.

[0070] In some implementations, such as Figure 1 As shown, at least one glass ball screw 324 is provided in the first receiving cavity 321. Figure 3 As shown, the rack 2032 has at least one ball screw positioning hole 2033. The ball screw 324 can move with the rack 2032. When the axis of the ball screw 324 coincides with the axis of the ball screw positioning hole 2033, the steel ball of the ball screw 324 can partially fall into the ball screw positioning hole 2033. At this time, the two adjacent display cabinets 30 are in a fully locked state. When the steel ball of the ball screw 324 partially falls into the ball screw positioning hole 2033, it provides a locking feel and serves as feedback.

[0071] During the process of releasing the two adjacent display cabinets 30, the glass ball screw 324 moves with the rack 2032. When the axis of the glass ball screw positioning hole 2033 does not coincide with the axis of the glass ball screw 324, the steel ball of the glass ball screw 324 can be disengaged from the glass ball screw positioning hole 2033.

[0072] In some implementations, such as Figure 3 As shown, the rack 2032 includes a toothed section 2034, a connecting section 2035, and a moving section 2036 connected in sequence. That is, the toothed section 2034 is connected to the moving section 2036 via the connecting section 2035. The toothed section 2034 meshes with the gear 2031, and the end of the moving section 2036 away from the connecting section 2035 is connected to the locking tongue 201. Since the toothed section 2034 meshes with the gear 2031, when the gear 2031 rotates, the meshing connection causes the toothed section 2034 to move along a first direction, which in turn causes the moving section 2036 to move along the first direction via the connecting section 2035, ultimately causing the locking tongue 201 to move along the first direction.

[0073] The angle between the connecting section 2035 and the toothed section 2034 is obtuse, as is the angle between the connecting section 2035 and the moving section 2036. In other words, the entire rack 2032 presents a Z-shape. This ensures that the locking tongue 201 has sufficient range of motion in the first direction while also reducing the length of the entire transmission component 203 in the first direction, thus saving installation space and achieving a smooth transition.

[0074] The included angle between the connecting section 2035 and the gear tooth section 2034 can be 155°, and the included angle between the connecting section 2035 and the moving section 2036 can also be 155°. The overall length of the rack 2032 can be three-fifths of the width of the display housing 30. The length of the locking tongue 201 can be approximately one-seventh of the overall length of the rack 2032.

[0075] Figure 4 This is a schematic perspective view of a casing provided in an embodiment of this application. In some embodiments, such as Figure 3 and Figure 4 As shown, the linkage assembly 20 also includes a housing 204, within which a first mounting portion 2041 is provided for mounting the gear 2031. The first mounting portion 2041 has a second shaft hole 2043, the axis of which coincides with the axis of the first shaft hole 323. Therefore, when the drive shaft 2021 passes through the first shaft hole 322, it can also pass through the second shaft hole 2043. Alternatively, when the drive end of the drive handle 2022 passes through the first shaft hole 322, it can also pass through the second shaft hole 2043. This allows the end of the drive shaft 2021 away from the drive handle 2022 to be connected to the gear 2031.

[0076] like Figure 3 and Figure 4 As shown, the outer casing 204 also includes two second mounting portions 2042, each used to mount a rack 2032. That is, the two second mounting portions 2042 are respectively located on both sides of the first mounting portion 2041, corresponding to the positions of the two racks 2032. The two racks 2032 are respectively disposed within the two second mounting portions 2042.

[0077] Since the rack 2032 is Z-shaped, the corresponding second mounting part 2042 can also be adapted to be Z-shaped. The multiple sidewalls of the second mounting part 2042 are parallel to the multiple sidewalls of the rack 2032. This further saves installation space for the entire splicing device.

[0078] In some embodiments, at least one positioning post 2044 may be provided outside the housing 204, for example, such as... Figure 3 The two positioning posts 2044 are shown. Positioning holes corresponding to the positions of the positioning posts 2044 are provided on the side wall of the first receiving cavity 321. Figure 3 (Not shown in the image), the axis of the positioning pin 2044 coincides with the axis of the positioning hole at the corresponding position. When installing the housing 204, the gear 2031 and rack 2032 housed within the housing 204 can be installed inside the housing 204 first, and then the housing 204 can be placed into the first receiving cavity 321 through the opening of the first receiving cavity 321. During the installation of the housing 204, the positioning pin 2044 is inserted into the positioning hole at the corresponding position, thereby installing the gear 2031 and rack 2032 in the corresponding positions, facilitating subsequent locking and unlocking operations.

[0079] Figure 5 This is a schematic perspective view of a rack provided in an embodiment of this application. In some embodiments, such as Figure 3 and Figure 5 As shown, the outer casing 204 has a through hole 2045 at its end in the first direction, through which the latch 201 can pass. The outer casing 204 has a limiting step 2046 at its end in the first direction, and the moving section 2036 of the rack 2032 has a limiting part 2037. When the latch 201 is inserted into the lock hole 101 in the first direction, the limiting part 2037 abuts against the limiting step 2046.

[0080] In other words, when the moving segment 2036 moves along the first direction with the latch 201, the latch 201 can pass through the through hole 2045, while the limiting part 2037 cannot pass through the limiting step 2046. Therefore, when the moving segment 2036 drives the latch 201 to be fully inserted into the lock hole 101, the limiting part 2037 abuts against the limiting step 2046. At this time, the moving segment 2036 can no longer move along the direction of insertion into the lock hole 101 with the latch 201. In this way, it can be avoided that the latch 201 is inserted into the lock hole 101 too much, causing the end of the latch 201 to contact the side wall of the first receiving cavity 321, thus causing wear on the latch 201 and the side wall of the first receiving cavity 321.

[0081] In some implementations, such as Figure 3 and Figure 5 As shown, the housing 204 also has a guide post 2047 corresponding to the moving section 2036 inside. The moving section 2036 has a guide groove 2038, which is sleeved on the guide post 2047 and can move relative to the guide post 2047 in a first direction. The length of the guide groove 2038 can be approximately one-sixth of the overall length of the rack 2032.

[0082] like Figure 4 As shown, a guide post mounting position 2048 can be provided inside the housing 204. The guide post mounting position 2048 is formed by a shaft with holes, and a reinforcing rib is connected between the shaft with holes and the side wall of the housing 204 to improve the stability of the shaft with holes. The guide post 2047 is mounted on the guide post mounting position 2048. When the moving section 2036 of the rack 2032 is installed in the housing 204, the guide groove 2038 is sleeved on the guide post 2047. Since the guide post 2047 is fixed, the guide groove 2038 moves along the first direction under the restriction of the guide post 2047. Therefore, the moving section 2036 can drive the locking tongue 201 to move only along the first direction, making it easier for the locking tongue 201 to be inserted into the lock hole 101, further facilitating the locking operation and improving the efficiency of the splicing display device.

[0083] Figure 6 This is a schematic perspective view of a guide post provided in an embodiment of this application. In some embodiments, such as Figure 6 As shown, a second copper sleeve 2039 can also be fitted onto the guide post 2047. The second copper sleeve 2039 can rotate about the axis of the guide post 2047. Simultaneously, the sidewall of the guide groove 2038 directly contacts the outer wall of the second copper sleeve 2039. That is, when the guide groove 2038 moves relative to the guide post 2047 in the first direction, it drives the second copper sleeve 2039 to rotate about the axis of the guide post 2047. This provides smooth sliding for the rack 2032, improving the feel during locking and unlocking operations.

[0084] Figure 7 yes Figure 1 Enlarged view of region A in the middle. In some implementations, such as... Figure 7 As shown, the locking tongue 201 includes a main body segment 2011, an arc-shaped connecting segment 2012, and an inlet segment 2013 connected in sequence. The main body segment 2011 is connected to the driving component 202, meaning that the main body segment 2011 is connected to the moving segment 2036 of the rack 2032. The cross-sectional area of ​​the arc-shaped connecting segment 2012 gradually decreases along the axial direction of the arc-shaped connecting segment 2012 from the end of the main body segment 2011 to the end of the inlet segment 2013. In other words, an inclined surface is formed between the main body segment 2011 and the inlet segment 2013, which makes the locking tongue 201 insert into the lock hole 101 more smoothly, further improving the efficiency of the splicing display device.

[0085] Figure 8 This is a schematic perspective view of a gear provided in an embodiment of this application. Figure 9 This is a schematic perspective view of yet another type of gear provided in an embodiment of this application. In some embodiments, such as Figure 8 and Figure 9 As shown, gear 2031 includes a cylindrical gear body, and teeth arranged annularly around the axis of the gear body are provided on the outside of the gear body. The top of the gear body is provided with a hexagonal prism-shaped blind hole, into which the drive shaft 2021 can be inserted, thereby connecting the drive shaft 2021 to the gear 2031.

[0086] A base post 2030 is also provided at the bottom of the gear body. The axis of the base post 2030 coincides with the axis of the gear body, and the bottom diameter of the base post 2030 is smaller than the bottom diameter of the gear body. For example... Figure 1 As shown, the bottom of the first receiving cavity 321 is provided with a gear receiving groove 3211 for receiving the gear 2031. The gear receiving groove 3211 is a stepped groove. The bottom post 2030 of the gear 2031 can be entirely disposed within the gear receiving groove 3211, while the gear body can be partially disposed within the gear receiving groove 3211. The gear 2031 can rotate within the gear receiving groove 3211. That is to say, the gear receiving groove 3211 only serves to support and accommodate the gear 2031. The bottom post 2030 being disposed within the gear receiving groove 3211, and the gear body being partially disposed within the gear receiving groove 3211, can restrict the position of the gear 2031, preventing the gear 2031 from shifting position along the first direction.

[0087] Based on the splicing device described in the above embodiments, the following is a detailed explanation of the cooperation relationship between the various components during the locking and unlocking process of two adjacent display cabinets.

[0088] Figure 10 This is a schematic application diagram of two adjacent display cabinets in a released state, provided in an embodiment of this application. Figure 11 This is a schematic cross-sectional view of two adjacent display cabinets in a released state, provided in an embodiment of this application. Figure 12 yes Figure 11 A magnified view of area B in the image.

[0089] like Figures 10 to 12 As shown, the two adjacent display cabinets 30 are in the loosened state. At this time, the locking pin assembly 10 is not inserted into the fixing hole 322. Figures 10 to 12 In the example, the drive handle 2022 can be in the initial position, at which time the axis of the handle end of the drive handle 2022 can be parallel to the first direction.

[0090] Figure 13 This is a schematic application diagram illustrating the locking process of two adjacent display cabinets provided in an embodiment of this application. Figure 14 This is a schematic cross-sectional view of the locking process of two adjacent display cabinets provided in an embodiment of this application. Figure 15 yes Figure 14 Sectional view of region C in the diagram.

[0091] like Figures 13 to 15 As shown, the two adjacent display housings 30 are in a state between loosening and locking. At this time, the locking pin assembly 10 has been inserted into the fixing hole 322. From Figures 10 to 13 The drive handle 2022 rotates clockwise around the drive shaft 2021, and the axis of the handle end of the drive handle 2022 changes from being parallel to the first direction to forming an angle with the first direction. During this process, the drive handle 2022 simultaneously drives the gear 2031 to rotate clockwise via the drive shaft 2021. The gear 2031 drives the meshing rack 2032 on both sides to move along the first direction. Specifically, it drives the rack 2032 to move in a direction away from the gear 2031. Therefore, when the drive handle 2022 rotates clockwise around the drive shaft 2021, the rack 2032 can drive the locking tongue 201 to insert into the lock hole 101 of the locking pin assembly 10.

[0092] It should be noted that the locking process is illustrated by the example of the drive handle 2022 rotating clockwise around the drive shaft 2021 to achieve locking. In actual application, locking can also be achieved in other directions of rotation. This application does not limit the direction of rotation of the drive handle 2022 to achieve locking.

[0093] Figure 15The two display cabinets 30 shown are not fully locked yet, with only part of the locking tongue 201's guide section 2013 inserted into the lock hole 101. At this point, the drive handle 2022 needs to be rotated further, causing it to continue rotating clockwise around the drive shaft 2021. Simultaneously, the drive handle 2022, through the drive shaft 2021, continues to drive the gear 2031 to rotate clockwise. The gear 2031 continues to drive the meshing racks 2032 on both sides to move along the first direction. This continues until the steel ball of the ball screw 324 falls into the ball screw positioning hole 2033. At this point, the steel ball of the ball screw 324 falling into the ball screw positioning hole 2033 will generate feedback, providing a noticeable tactile feedback to the operator. Simultaneously, the two adjacent display cabinets 30 achieve precise alignment in all directions, completing the locking action of the two adjacent display cabinets 30.

[0094] Figure 16 This is a schematic application diagram of two adjacent display cabinets in a locked state, provided in an embodiment of this application. Figure 17 This is a schematic cross-sectional view of two adjacent display cabinets in a locked state, provided in an embodiment of this application. Figure 18 This is a magnified view of region D in 17.

[0095] like Figures 16-18 As shown, when the two display boxes 30 are in the locked state, the guide section 2013 of the locking tongue 201 completely passes through the lock hole 101, part of the arc-shaped connecting section 2012 of the locking tongue 201 passes through the lock hole 101, and at the same time, part of the main body section 2011 of the locking tongue 201 is located inside the lock hole 101.

[0096] It should be noted that when the drive handle 2022 rotates clockwise around the drive shaft 2021, the rack 2032 simultaneously drives the two racks 2032 on both sides to move along the first direction. Therefore, during the locking process, the locking tongues 201 on both sides are inserted into the corresponding lock holes 201. Simultaneous locking on both sides is achieved by inserting the locking tongues 201 into the corresponding lock holes 201, making the locking of the two display cabinets 30 more secure. Furthermore, in this embodiment, the rotation of the drive handle 2022 drives the gear 2031 to rotate, and then the gear 2031 drives the two racks 2032 to move in opposite directions, thus achieving simultaneous locking on both sides. Therefore, locking on both sides can be achieved with one hand, making operation simple and the locking efficiency high.

[0097] Figure 19 yes Figure 17 A magnified view of region E in the image. In some implementations, such as... Figure 18 and Figure 19As shown, when the two display housings 30 are in the locked state, the guide section 2013 of the locking tongue 201 completely passes through the lock hole 101, and part of the arc-shaped connecting section 2012 of the locking tongue 201 passes through the lock hole 101, while part of the main body section 2011 of the locking tongue 201 is located inside the lock hole 101. The bottom of the guide section 2013 can contact the bottom of the first receiving cavity 321, and the bottom of the main body section 2011 can also contact the bottom of the first receiving cavity 321. This is equivalent to both ends of the locking tongue 201 contacting the bottom of the first receiving cavity 321. Since the locking tongue 201 is inserted into the fixing hole 322, the middle section of the locking tongue 201 does not contact the bottom of the first receiving cavity 321, resulting in the middle section of the locking tongue 201 being suspended.

[0098] like Figure 18 As shown, the axis of the latch 201 is parallel to but not collinear with the axis of the lock hole 101. Thus, after the latch 201 is inserted into the lock hole 101, its top contacts the top of the lock hole 101 because the axis of the latch 201 is parallel but not collinear with the axis of the lock hole 101. Furthermore, because the middle section of the latch 201 is suspended, and its axis is not collinear with the lock hole 101, the locking pin assembly 10, along with the lower display housing 30, is suspended on the middle section of the latch 201. This results in the middle section of the latch 201 being subjected to the gravity of the lower display housing 30, while the two ends of the latch 201 are supported by the bottom of the first receiving cavity 321. Since forces are reciprocal, the lower display housing 30 also experiences an upward pulling force from the latch 201. This allows the sides of adjacent display housings 30 to fit more tightly, resulting in a better locking effect.

[0099] If it is necessary to move the two display cabinets 30 from Figures 16 to 18 The locked state is changed to the unlocked state, meaning that the two display cabinets 30 need to be released. Figures 16 to 18 In the locked state shown, the drive handle 2022 is rotated counterclockwise. The drive handle 2022 rotates counterclockwise around the drive shaft 2021, and at the same time, the drive handle 2022 drives the gear 2031 to rotate counterclockwise through the drive shaft 2021.

[0100] Gear 2031 drives rack 2032, which meshes on both sides, to move along a first direction. Specifically, it drives rack 2032 to move along a direction closer to gear 2031. Therefore, when drive handle 2022 rotates counterclockwise around drive shaft 2021, rack 2032 can drive latch 201 to disengage from lock hole 101 of lock pin assembly 10. At this time, the ball of ball screw 324 also disengages from ball screw positioning hole 2033. Drive handle 2022 rotates to Figures 13 to 15 When the state shown is reached, both display boxes 30 are in the process of being released.

[0101] exist Figures 13 to 15 In the indicated state, as the drive handle 2022 continues to rotate counterclockwise (i.e., as the drive handle 2022 rotates counterclockwise around the drive shaft 2021), the drive handle 2022 continues to drive the gear 2031 to rotate counterclockwise via the drive shaft 2021. Simultaneously, the gear 2031 drives the rack 2032 to continue moving along the direction closer to the gear 2031. The rack 2032 then drives the latch 201 to continue moving along the direction closer to the gear 2031, meaning the latch 201 continues to disengage from the lock hole 101 until the drive handle 2022 returns to its original position. Figures 10 to 12 The initial position is shown. At this time, the locking tongue 201 is also completely disengaged from the lock hole 101, completing the release action of the two display boxes.

[0102] The second aspect of this application provides a splicing display device, which includes at least two display cabinets 30 and the splicing device provided in the first aspect. Two adjacent display cabinets 30 are spliced ​​together by the splicing device. Since the splicing device of this application only requires the operation of a driving component to complete the locking and unlocking actions of two adjacent display cabinets 30, the locking and unlocking operations can be simplified, thereby improving the splicing and installation efficiency of the splicing display device.
