[0002] Column-wrapped exhibition wall frame refers to a display system or structure designed around the columns inside the building to increase the utilization efficiency and visual effect of the space. It includes structural frames, decorative panels, etc. Among them, the structural frame is usually a frame made of metal (such as aluminum, steel), wood or composite materials to support the entire display system. Decorative panels are used to cover the surface of the column, which can be wood, metal, stone, glass or synthetic materials. These panels can not only hide the original columns, but also provide color, texture and texture according to design requirements.

[0003] However, the existing column-wrapped exhibition wall frame is usually made by cutting the column-wrapped materials, such as wood and metal columns, according to the length and width of the building columns on site, and then assembling and fastening them with bolts to adapt to the building columns on site, thereby achieving column wrapping. However, it cannot be recycled. When the column-wrapped exhibition wall frame is disassembled, it is no longer applicable to building columns of different sizes, which greatly increases the manufacturing cost.

[0018] (III) Beneficial effects

[0019] The beneficial effects of the utility model are:

[0020] 1. The utility model discloses a frame assembly of a column-wrapped exhibition wall frame and a column-wrapped exhibition wall frame for exhibition. A locking device is vertically arranged in a movable frame, and the top of the lock of the locking device can extend and retract vertically through a fixed frame and a movable frame to lock or unlock the movable frame and the fixed frame, thereby changing the horizontal size of the column-wrapped exhibition wall frame, so that the column-wrapped exhibition wall frame can adapt to building columns of different sizes. The column-wrapped exhibition wall frame has stronger adaptability, improves recycling rate, has lower production cost, and has higher efficiency in installation and disassembly. At the same time, by installing the locking device inside the movable frame, it can improve space utilization, and the locking device can be more stable when locking the fixed frame and the movable frame, thereby improving the stability of the column-wrapped exhibition wall frame. The utility model can change the horizontal size of the column-wrapped exhibition wall frame by arranging a movable frame, a fixed frame and a locking device, so that it can be more suitable for building columns of multiple sizes, improve recycling rate, and reduce production cost.

[0021] 2. The utility model relates to a frame assembly of a column-wrapped exhibition wall frame and a column-wrapped exhibition wall frame for exhibition.

The locking end of the locking device can vertically pass through the second clamping hole and be clamped with the first clamping hole corresponding to it among the plurality of first clamping holes, thereby locking the movable frame and the fixed frame. Moreover, when the locking end is retracted into the column, the movable frame and the fixed frame are unlocked, and the movable frame is in an active state, so that the movable frame can move in the movable space to change the horizontal size of the frame assembly, thereby improving the applicability of the column-wrapped exhibition wall frame and reducing the production cost.

[0022] 3. The utility model provides a frame assembly of a column-wrapped exhibition wall frame and a column-wrapped exhibition wall frame for exhibition, which realizes precise locking and unlocking between a movable frame and a fixed frame through the coordinated work of a locking mechanism and a driving mechanism. One end of the driving mechanism is connected to the fixed end of the locking mechanism, and the other end extends to the outer wall of the column, so that the operator does not need to directly contact the complex structure inside the column, but only needs to manipulate the exposed part of the driving mechanism to easily control the telescopic action of the locking mechanism, which greatly improves the convenience and efficiency of operation. By setting two locking mechanisms, it can make the movable frame more stable when locked with the fixed frame, avoiding the phenomenon of movement between the movable frame and the fixed frame. At the same time, one driving mechanism drives the two locking mechanisms to telescope at the same time, making the operation easier and improving work efficiency.

[0023] 4. The utility model provides a frame assembly of a column-wrapped exhibition wall frame and a column-wrapped exhibition wall frame for exhibition. By setting gears, pull ropes and locking assemblies, one of the gears in the two locking mechanisms is driven to rotate by the driving mechanism, so that the other gear rotates synchronously, and then the two pull ropes are stretched or shortened at the same time, so as to drive the two locking assemblies to lock or unlock the movable frame and the fixed frame at the same time, thereby improving work efficiency and reducing the possibility of operational errors. By setting a limit plate, it can not only limit the stroke of the locking assembly, but also play a supporting role to ensure the vertical movement of the locking assembly. By setting a clamping rod and a first clamping hole, it can achieve a stable locking state to ensure that the position of the movable frame in the fixed frame is fixed. By setting a first elastic member, when the pull rope pulls the clamping rod and shortens, the clamping rod receives an external force, and the first elastic member is compressed to store energy. Once the external force disappears, the restoring force of the first elastic member will automatically push the clamping rod back to the initial position and lock it with the first clamping hole. This not only simplifies the operation, but also acts as a buffer, protecting the clamping rod and the first clamping hole from hard collisions and extending the service life of the equipment.

[0024] 5. The utility model is a frame assembly and a column-wrapped exhibition wall frame for exhibitions. One end of a rotating rod is connected to one of the gears in the two locking mechanisms. When the driving member acts on the rotating rod, it can drive the gear to rotate smoothly, which ensures the accuracy and continuity of power transmission, so as to accurately control the telescopic action of the locking assembly and avoid structural damage that may be caused by fast or unstable operation. By setting a U-shaped limit hole and a limit block, it is possible to limit the rotation range of the rotating rod, thereby limiting the telescopic length of the locking assembly, and avoiding damage to the locking assembly due to the excessive telescopic length of the locking assembly. By setting a second elastic member, it is possible to provide a rebound force to the rotating rod, so that when the rotating rod needs to be locked after rotation, the second elastic member only needs to apply a rebound force to the rotating rod, and the limit block can be inserted into the U-shaped limit hole to lock the rotating rod. By setting the outer contour of the rotating rod to a polygon and the engaging portion between the gear and the rotating rod to a polygon, the rotating rod and the gear can be matched so that the rotating rod and the gear can not only be engaged but also the rotating rod can drive the gear to rotate.

[0025] 6. The utility model provides a frame assembly of a column-wrapped exhibition wall frame and a column-wrapped exhibition wall frame for exhibition. By setting a fixing bolt, a locking plate and a locking bolt, the locking plate can be rotated around the axis of the fixing bolt and the third clamping hole of the locking plate is clamped with the locking bolt, thereby realizing the connection between adjacent fixed frames and movable frames in four groups of frame assemblies, and fastening them through the locking bolts, thereby achieving a more stable connection between the four groups of frame assemblies and avoiding movement between the fixed frame and the movable frame.

On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0036] Embodiment 1

[0037] like Figure 1-Figure 7 As shown, a frame assembly 1 of a column-wrapped exhibition wall frame for exhibition in this embodiment is provided, wherein the frame assembly 1 includes a fixed frame body 11 , a movable frame body 12 and a locking device 2 .

[0038] Specifically, a moving space 111 is provided in the frame edge of the fixed frame 11, and the moving frame 12 is movably installed in the moving space 111. The locking device 2 is vertically installed inside the moving frame 12, and the locking device 2 has a locking end, and the locking end can be vertically extended between a locking position passing through the moving frame 12 and the fixed frame 11 at the same time and an unlocking position only located in the moving frame 12, so as to lock or unlock the moving frame 12 and the fixed frame 11. By vertically arranging the locking device 2 in the moving frame 12, and the locking top end of the locking device 2 can be vertically extended through the fixed frame 11 and the moving frame 12, the moving frame 12 and the fixed frame 11 are locked or unlocked, thereby realizing the change of the horizontal size of the column-wrapped exhibition wall frame, so that the column-wrapped exhibition wall frame is adapted to building columns of different sizes, the column-wrapped exhibition wall frame has stronger adaptability, improves the recycling rate, has lower production costs, and has higher efficiency in installation and disassembly. At the same time, by installing the locking device 2 inside the movable frame 12, it can improve space utilization, and the locking device 2 can be more stable when locking the fixed frame 11 and the movable frame 12, while improving the stability of the column-wrapped wall frame.

[0039] Further, the fixed frame 11 is a U-shaped frame, the closed side of the fixed frame 11 is arranged in a direction laterally away from the movable frame 12, and a plurality of parallel first engaging holes 112 with intervals are horizontally arranged on the top frame edge and / or the bottom frame edge of the fixed frame 11. The movable frame 12 is a rectangular frame and the rectangular frame is composed of four columns 121 connected end to end, and the top and / or the bottom of the column 121 has a second engaging hole. The locking device 2 is vertically installed inside a column 121 of the movable frame 12 close to the fixed frame 11, and the locking end of the locking device 2 can vertically pass through the second engaging hole and engage with the first engaging hole 112 corresponding to it among the plurality of first engaging holes 112 or retract into the column 121 to switch between the locked position and the unlocked position. By horizontally providing a plurality of first snap-in holes 112 on the fixed frame 11 and providing a second snap-in hole at the top and / or bottom of the column 121, the locking end of the locking device 2 can vertically pass through the second snap-in hole and snap-in with the first snap-in hole 112 corresponding to it among the plurality of first snap-in holes 112, thereby locking the movable frame 12 and the fixed frame 11, and when it is retracted into the column 121, the movable frame 12 and the fixed frame 11 are unlocked, so that the movable frame 12 is in an active state, so that the movable frame 12 can move in the movable space 111 to change the horizontal size of the frame assembly 1, thereby improving the applicability of the column-wrapped wall exhibition frame and reducing the production cost.

[0040] Furthermore, the locking device 2 includes a locking mechanism 21 and a driving mechanism 22. The locking mechanism 21 is vertically placed in the column 121, one end of the locking mechanism 21 is fixedly mounted on the inner wall of the column 121 through the fixing plate 5, and the other end constitutes a locking end. One end of the driving mechanism 22 is connected to the fixed end of the locking mechanism 21, and the other end passes through the outer wall of the column 121, which is used to receive the external operating force and convert it into a driving force for the locking end to switch between the locking position and the unlocking position through the locking mechanism 21, so that the operator does not need to directly contact the complex structure inside the column 121, and only needs to manipulate the exposed part of the driving mechanism 22 to easily control the telescopic action of the locking mechanism 21, which greatly improves the convenience and efficiency of the operation. Through the coordinated work of the locking mechanism 21 and the driving mechanism 22, accurate locking and unlocking between the movable frame 12 and the fixed frame 11 is achieved.

[0041] Furthermore, the top frame edge and the bottom frame edge of the fixed frame 11 are both provided with a first snap-in hole 112. The top wall and the bottom wall of the column 121 are both provided with a second snap-in hole. Two locking mechanisms 21 are provided, and the vertical midlines of the two locking mechanisms 21 are the same. The driving mechanism 22 can drive the two locking mechanisms 21 to extend and retract synchronously, so as to simultaneously lock or unlock the top wall and the bottom wall of the column 121 with the top and bottom fixed frames 11, so that the two locking mechanisms 21 can make the mobile frame 12 more stable when locked with the fixed frame 11, and avoid the phenomenon of movement between the mobile frame 12 and the fixed frame 11. At the same time, the two locking mechanisms 21 are driven to extend and retract simultaneously by one driving mechanism 22, so that the operation is easier and the work efficiency is improved.

[0042] Further, the locking mechanism 21 includes a gear 211, a pull rope 212 and a locking assembly 213, and the locking end is located in the locking assembly 213. The gear 211 is rotatably mounted on the fixed plate 5 through the rotating shaft 214, and the axis of the gear 211 is perpendicular to the vertical center line of the fixed plate 5. One end of the pull rope 212 is wound around the outer wall of the rotating shaft 214, and the other end is connected to the end of the locking assembly 213 away from the movable frame 12. The inner end of the column 121 is horizontally mounted with a limit plate 4, and the two ends of the locking assembly 213 can pass through the second clamping hole and the limit plate 4 respectively. The limit plate 4 can not only limit the travel of the locking assembly 213, but also play a supporting role to ensure the vertical movement of the locking assembly 213. The two locking mechanisms 21 are arranged vertically opposite to each other, and the two gears 211 in the two locking mechanisms 21 are meshed with each other. The driving mechanism 22 is connected to one of the gears 211 and the driving mechanism 22 can drive one of the gears 211 to rotate, so as to synchronously drive the other gear 211 to rotate, so that the pull ropes 212 of the two locking mechanisms 21 are synchronously lengthened or shortened, so as to drive the locking components 213 of the two locking mechanisms 21 to synchronously pass through the corresponding second clamping holes and the first clamping holes 112 in sequence and lock with the first clamping holes 112 or sequentially retract from the corresponding first clamping holes 112 and the second clamping holes into the column 121 to unlock. That is, when the mobile frame 12 and the fixed frame 11 are locked, the two pull ropes 212 located at the top and the bottom are synchronously lengthened by the driving mechanism 22, and the two locking components 213 located at the top and the bottom synchronously pass through the second clamping holes located at the top and the bottom of the column 121 in sequence, and the two first clamping holes 112 at the top and the bottom of the fixed frame 11 corresponding to the two second clamping holes at this time, so that the mobile frame 12 is fixed to the fixed frame 11 through the two locking components 213 at the top and the bottom. Alternatively, when the movable frame 12 and the fixed frame 11 are unlocked, the two pull ropes 212 located at the top and the bottom are synchronously shortened by the driving mechanism 22, and the two locking components 213 located at the top and the bottom synchronously pass through the two first clamping holes 112 located at the top and the bottom of the fixed frame 11 at this time, and the second clamping holes at the top and the bottom of the column 121 corresponding to the two first clamping holes 112 at this time, and retract into the column 121, so that the movable frame 12 is unlocked from the fixed frame 11 by the two locking components 213 at the top and the bottom. By setting the gear 211, the pull rope 212 and the locking component 213, one of the gears 211 in the two locking mechanisms 21 is driven to rotate by the driving mechanism 22, so that the other gear 211 rotates synchronously, and then the two pull ropes 212 are stretched or shortened at the same time, so as to drive the two locking components 213 to lock or unlock the movable frame 12 and the fixed frame 11 at the same time, thereby improving work efficiency and reducing the possibility of operation errors.

[0043] Furthermore, the locking assembly 213 includes a first mounting plate 2131 , a clamping rod 2132 , a second mounting plate 2133 and a first elastic member 2134 .

[0044] Specifically, the first mounting plate 2131, the second mounting plate 2133 and the first elastic member 2134 are all sleeved on the outer wall of the clamping rod 2132, and the first mounting plate 2131 is connected to the outer wall of the clamping rod 2132. One side wall of the first mounting plate 2131 can fit with the inner wall of the column 121, and one side wall of the second mounting plate 2133 always fits with the side wall of the limiting plate 4 away from the gear 211. The first elastic member 2134 is located between the first mounting plate 2131 and the second mounting plate 2133, and the two ends of the first elastic member 2134 are respectively connected to the first mounting plate 2131 and the second mounting plate 2133. By providing the first elastic member 2134, when the pull rope 212 pulls the clamping rod 2132 and shortens, the clamping rod 2132 receives external force, and the first elastic member 2134 is compressed to store energy. Once the external force disappears, the restoring force of the first elastic member 2134 will automatically push the clamping rod 2132 back to the initial position and lock with the first clamping hole 112, which not only simplifies the operation, but also plays a buffering role, protects the clamping rod 2132 and the first clamping hole 112 from hard collision, and prolongs the service life of the device. The clamping rod 2132 is vertically arranged and one end of the clamping rod 2132 can pass through the end of the column 121 to cooperate with the first clamping hole 112, and the other end of the clamping rod 2132 is connected with the pull rope 212. The pull rope 212 can simultaneously drive the clamping rod 2132 and the first mounting plate 2131 to vertically extend and retract, so that the clamping rod 2132 and the first clamping hole 112 are locked or unlocked. By setting the clamping rod 2132 and the first clamping hole 112, it can achieve a stable locking state, ensuring that the position of the mobile frame 12 in the fixed frame 11 is fixed.

[0045] Furthermore, the driving mechanism 22 includes a sleeve 221 , a rotating rod 222 and a driving member 223 .

[0046] Specifically, one end of the sleeve 221 is vertically connected to one of the gears 211 in the two locking mechanisms 21 and the axis of the sleeve 221 is the same as the axis of the gear 211, and the other end is fixedly connected to the column 121 and passes through the outer wall of the column 121. A U-shaped limiting hole 2211 is provided on the outer wall of the sleeve 221. The rotating rod 222 is placed inside the sleeve 221 and one end of the rotating rod 222 is engaged with the gear 211, and the other end is engaged with the driving member 223, which is used to drive the rotating rod 222 to rotate. When the driving member 223 acts on the rotating rod 222, it can drive the gear 211 to rotate smoothly, which ensures the accuracy and continuity of power transmission, so as to accurately control the telescopic action of the locking assembly 213 and avoid structural damage that may be caused by fast or unstable operation. A limiting block 2221 is vertically connected to the outer wall of the rotating rod 222, and the limiting block 2221 is placed in the limiting hole 2211. When the limit blocks 2221 are placed on the two side edges of the U-shape, the rotating rod 222 is fixed, and when the limit blocks 2221 are located in the middle edge of the U-shape, the rotating rod 222 can drive the gear 211 to rotate. By providing the U-shaped limit hole 2211 and the limit blocks 2221, the rotation range of the rotating rod 222 can be limited, so that the telescopic length of the locking assembly 213 is limited, and the locking assembly 213 is prevented from being damaged due to the excessive telescopic length of the locking assembly 213. Preferably, the outer contour of the rotating rod 222 is a polygon, and the clamping part between the gear 211 and the rotating rod 222 is also a polygon, which can realize the cooperation between the rotating rod 222 and the gear 211, so that the rotating rod 222 and the gear 211 can not only be clamped, but also the rotating rod 222 can drive the gear 211 to rotate.

[0047] Furthermore, the driving mechanism 22 further includes a second elastic member 224. The second elastic member 224 is disposed inside the sleeve 221 and sleeved on the outer wall of the rotating rod 222, and is used to provide a rebound force to the rotating rod 222, so that when the rotating rod 222 needs to be locked after the rotating rod 222 is rotated, the second elastic member 224 only needs to apply a rebound force to the rotating rod 222, so that the limit block 2221 can be inserted into the U-shaped limit hole 2211, and the rotating rod 222 is locked.

[0048] Through the above structure, the working principle of the frame assembly 1 of the column-wrapped exhibition wall frame for exhibition in this embodiment is as follows:

[0049] like Figure 1-Figure 7As shown, first, the locking device 2 is installed inside the column 121, and then the mobile frame 12 is placed in the moving space 111 of the fixed frame 11. The fixed frame 11 and the mobile frame 12 are moved to the building column. Then, the driving member 223 is inserted into the rotating rod 222, the rotating rod 222 is pressed, and the second elastic member 224 is compressed, so that the limit block 2221 moves from one side of the U-shaped limit hole 2211 to the end point of the middle side, and the driving member 223 is rotated to rotate the rotating rod 222 along the middle side, thereby driving one of the gears 211 in the two locking mechanisms 21 to rotate, and driving the other gear 211 to rotate synchronously. Next, the two pull ropes 212 are driven to be synchronously wound around the two rotating shafts 214, so that the two pull ropes 212 simultaneously drive the two clamping rods 2132 to move vertically toward the direction of the two gears 211, so that the two clamping rods 2132 are retracted into the column 121. At this time, the mobile frame 12 is in an active state. At the same time, the rotation of the rotating rod 222 is stopped, and no force is applied to the rotating rod 222. Due to the rebound force of the second elastic member 224, the limit block 2221 on the rotating rod 222 enters the other side of the U-shaped limit hole 2211, so that the rotating rod 222 is fixed and no longer rotates. At this time, the first elastic member 2134 is compressed. Then, according to the width of the building column on site, the movable frame 12 is moved so that the movable frame 12 moves in the movable space 111.

[0050] When the mobile frame 12 moves to the designated position, the force is continuously applied to the rotating rod 222, and the second elastic member 224 is compressed, so that the limit block 2221 moves from one side of the current U-shaped side to the end point of the middle side. Then the driving member 223 is driven to drive the rotating rod 222 to rotate, thereby driving one of the gears 211 in the two locking mechanisms 21 to rotate, and driving the other gear 211 to rotate at the same time. The two pull ropes 212 are released from the two rotating shafts 214 to drive the clamping rod 2132 to move vertically in the direction away from the two gears 211. Due to the resilience of the first elastic member 2134, the two clamping rods 2132 pass through the two second clamping holes and the two first clamping holes 112 currently aligned in sequence and clamp with the two current first clamping holes 112 to achieve the fixing of the mobile frame. At this time, the length or width of the frame assembly 1 is changed to adapt to the length or width of the building column on site.

[0051] When it is necessary to wrap other building columns again, continue the above operations, which will not be repeated here.

The four groups of frame assemblies 1 are all vertically arranged and connected end to end by a plurality of connectors 3 to form a rectangular frame. The connector 3 includes a fixing bolt 31, a locking plate 32 and a locking bolt 33. The fixing bolt 31 and the locking bolt 33 are respectively fixedly mounted on the outer wall of the movable frame 12 or the fixed frame 11, one end of the locking plate 32 is rotatably connected to the fixing bolt 31, and the other end is provided with a third clamping hole 321, and the third clamping hole 321 can be clamped with the locking bolt 33. The locking bolt 33 can lock or loosen the locking plate 32, so that the fixed frame 11 and the movable frame 12 are locked or unlocked. By providing a fixing bolt 31, a locking plate 32 and a locking bolt 33, it is possible to realize that the locking plate 32 can rotate around the axis of the fixing bolt 31 and enable the third engaging hole 321 of the locking plate 32 to engage with the locking bolt 33, thereby realizing the connection between the adjacent fixed frames 11 and movable frames 12 in the four groups of frame assemblies 1, and fastening them through the locking bolt 33, thereby realizing a more stable connection between the four groups of frame assemblies 1, and avoiding movement between the fixed frame 11 and the movable frame 12.
