Description
Technical Field
[0001] This utility model relates to the field of split bed technology, and in particular to an expansion connection structure for a split bed. Background Technology
[0002] A modular bed typically has at least two bed frames that can be joined together to form a larger unit for use. Each bed frame has a connector underneath, which is a component used to connect the bed frames into a whole. The connectors under the bed frames are connected to each other, thereby connecting at least two bed frames into a whole. Currently, split-type beds lack supporting structures at the joints of the connecting parts, simply connecting the parts into a single unit. This causes the connecting parts to dent and bend downwards at the joints after prolonged use, leading to the risk of the split-type bed collapsing. Utility Model Content
[0003] The purpose of this utility model is to provide an expansion connection structure for a split bed, which can abut against the supporting connector upwards and prevent the connector from bending downwards from the connection point.
[0004] To achieve the above objectives, the solution of this utility model is as follows: An expansion connection structure for a split bed is disclosed. The split bed has at least two bed frames, each with a connector at its bottom. The connectors under the bed frames are connected by the expansion connection structure, thereby allowing the at least two bed frames to be spliced into a whole. The expansion connection structure includes a first connecting block and a second connecting block. The second connecting block is slidably disposed on the upper side of the first connecting block with a wedge. The connector includes at least a first sidewall and a second sidewall. The first sidewall is fixedly connected to the bottom of the bed frame, and the second sidewall is disposed on the lower side of the first sidewall. The first connecting block and the second connecting block span the connectors of at least two bed frames. The first connecting block can move closer to or away from the second sidewall. When moving closer, the first connecting block and the second sidewalls of the at least two connectors slide upward against the wedge of the second connecting block. The rising second connecting block can be supported upward against the lower sidewall of the at least two connectors.
[0005] Furthermore, the connector also includes a third sidewall, which is disposed below the second sidewall. The expansion connection structure also includes a third connecting block, which is slidably disposed below the first connecting block. The third connecting block spans at least the third sidewalls of the two bed connectors. When the first connecting block approaches the second sidewall, the first connecting block and the second sidewalls of at least two connectors can jointly abut against the wedge of the third connecting block and slide downward, so that the third connecting block abuts downward against the upper part of the third sidewalls of at least two connectors.
[0006] Furthermore, the bed has two parts that can be joined together to form a whole. An expansion connection structure spans the connectors of the two bed parts. The first connecting block spans the second sidewall of the two connectors. The second connecting block simultaneously abuts against the lower part of the first sidewall of the two connectors, and the third connecting block simultaneously abuts against the upper part of the third sidewall of the two connectors.
[0007] Furthermore, the expansion connection structure also includes a locking component, which can drive the first connecting block to move closer to or further away from the second sidewall. It can also connect the first connecting block to the second sidewall of at least two connectors simultaneously, and when the second connecting block is abutted and supported under the first sidewall of at least two connectors, the locking component can lock the movement of the first connecting block.
[0008] Furthermore, the locking component includes locking bolts and threaded holes. Multiple threaded holes are provided on the first connecting block and are spaced apart along the length of the first connecting block. When the first connecting block spans at least two connecting members, the multiple threaded holes are distributed within the second sidewall range of at least two connecting members. Multiple locking bolts pass through the second sidewall and are screwed into the threaded holes one by one, thereby simultaneously screwing the first connecting block onto at least two second sidewalls. When the locking bolts rotate in the direction of screwing into the threaded holes, they can drive the first connecting block to move closer to the second sidewall; conversely, they move away from the second sidewall.
[0009] Furthermore, the upper side of the first connecting block has an upwardly inclined first slope, and the lower side has a downwardly inclined second slope. The lower side of the second connecting block has a third slope that matches the first slope, and the third slope wedges into the first slope. The upper side of the third connecting block has a fourth slope that matches the second slope, and the fourth slope wedges into the second slope.
[0010] Furthermore, the second connecting block is provided with a first strip hole along its sliding direction. The second connecting block is screwed onto the first inclined surface after the first bolt passes through the first strip hole. When the second connecting block slides obliquely on the first connecting block, the first bolt can guide the sliding of the second connecting block. The third connecting block is provided with a second strip hole along its sliding direction. The third connecting block is screwed onto the second inclined surface after the second bolt passes through the second strip hole. When the third connecting block slides obliquely on the first connecting block, the second bolt can guide the sliding of the third connecting block.
[0011] Furthermore, the cross-section of the first connecting block is an isosceles trapezoid, with the upper base of the first connecting block facing the second side wall, and the two sides of the first connecting block facing the first side wall and the third side wall respectively. The cross-sections of the second connecting block and the third connecting block are right triangles. The hypotenuse of the second connecting block is fitted onto the side of the first connecting block facing the first side wall, and the hypotenuse of the third connecting block is fitted onto the side of the first connecting block facing the third side wall.
[0012] Furthermore, the connector is tubular.
[0013] Furthermore, the tubular connector has a rectangular cross-section, its top wall is the first side wall, its bottom wall is the third side wall, and any side wall adjacent to the top wall of the tubular connector is the second side wall.
[0014] After adopting the above solution, the beneficial effects of this utility model are as follows: This utility model uses a first connecting block and a second connecting block to connect at least two bed bodies. The first connecting block can move closer to or away from the direction of the second side wall. The second connecting block is slidably wedge-shaped and disposed on the upper side of the first connecting block. When the first connecting block moves closer to the second side wall, the first connecting block and the second side walls of at least two connecting parts slide and rise together against the wedge-shaped second connecting block, so that the second connecting block is rigidly supported below the first side walls of at least two connecting parts. This supports the first side walls of at least two connecting parts to remain on the same plane and prevents at least two connecting parts from bending or concave downward from the connection point.

Detailed Implementation
[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0018] like Figures 1-10 As shown, this embodiment provides an expansion connection structure for a split bed. The split bed 1 has at least two bed bodies 10, and each bed body 10 is provided with a connector 20 at its bottom. The connectors 20 under each bed body 10 are connected by an expansion connection structure 30, so that at least two bed bodies 10 can be spliced into a whole. The expansion connection structure 30 includes a first connecting block 31 and a second connecting block 32. The second connecting block 32 is slidably disposed on the upper side of the first connecting block 31. The connector 20 includes at least a first side wall 21 and a second side wall 22. The first side wall 21 is fixedly connected to the bottom of the bed body 10, and the second side wall 22 is disposed on the lower side of the first side wall 21. The first connecting block 31 and the second connecting block 32 span at least two connectors 20 of the bed body 10. The first connecting block 31 can move closer to or away from the second side wall 22. When moving closer, the first connecting block 31 and the second side walls 22 of at least two connectors 20 jointly abut against the second connecting block 32 and slide upward. The second connecting block 32 can rise and abut against the lower side wall 21 of at least two connectors 20.
[0019] like Figures 7-8 To further prevent the connector 20 from buckling or bending at the connection point, the connector 20 also includes a third sidewall 23, which is located below the second sidewall 22. The expansion connection structure 30 also includes a third connecting block 33, which is slidably disposed below the first connecting block 31. The third connecting block 33 spans at least two bed body 10 connectors 20's third sidewalls 23. When the first connecting block 31 approaches the second sidewall 22, the first connecting block 31 and at least two connectors 20's second sidewalls 22... 2. The three connecting blocks 33 slide down together against the third connecting block 33, so that the third connecting block 33 abuts against the top of the third side wall 23 of at least two connecting members 20. The rigid downward pressure of the third connecting block 33 on the at least two third side walls 23 makes the at least two third side walls 23 lie on the same plane. The rigid upward support of the second connecting block 32 on the at least two first side walls 21 makes the at least two first side walls 21 lie on the same plane, thereby further preventing the connecting members 20 from being concave or bent at the connection.
[0020] In a preferred embodiment, there are two bed bodies 10, which can be spliced together to form a whole. Specifically, when the two bed bodies 10 are spliced together to form a whole, the connecting parts 20 at the bottom of the two bed bodies 10 are also spliced together to form a whole. An expansion connection structure 30 spans the connecting parts 20 of the two bed bodies 10, specifically spanning the splicing point of the two connecting parts 20. A first connecting block 31 spans the second side wall 22 of the two connecting parts 20, a second connecting block 32 simultaneously abuts upward against the bottom of the first side wall 21 of the two connecting parts 20, and a third connecting block 33 simultaneously abuts downward against the top of the third side wall 23 of the two connecting parts 20. Specifically, the number of connecting parts 20 under one bed body 10 can be set according to actual needs and is not limited here. This utility model preferably provides two connecting parts 20 under one bed body 10. When the two bed bodies 10 are spliced together, the two connecting parts 20 under one bed body 10 need to be connected one-to-one with the two connecting parts 20 under the other bed body 10.
[0021] Furthermore, the expansion connection structure 30 also includes a locking component. The locking component can drive the first connecting block 31 to move towards or away from the second sidewall 22. It can also connect the first connecting block 31 to the second sidewall 22 of at least two connectors 20 at the same time. When the second connecting block 32 is supported against the first sidewall 21 of at least two connectors 20, the locking component can lock the movement of the first connecting block 31 to lock the position of the first connecting block 31 and prevent the first connecting block 31 from moving away from the second sidewall 22, so that the second connecting block 32 is always rigidly supported against the first sidewall 21 of at least two connectors 20.
[0022] like Figure 4 As shown, specifically, the locking component includes locking bolts 312 and threaded holes 311. Multiple threaded holes 311 are provided on the first connecting block 31, and the multiple threaded holes 311 are spaced apart along the length direction of the first connecting block 31. When the first connecting block 31 spans at least two connecting members 20, the multiple threaded holes 311 are distributed within the range of the second sidewalls 22 of at least two connecting members 20. Multiple locking bolts 312 pass through the second sidewalls 22 and are screwed into the threaded holes 311 one by one, thereby simultaneously screwing the first connecting block 31 onto at least two second sidewalls 22. When the locking bolts 312 rotate in the direction of screwing into the threaded holes 311, they can drive the first connecting block 31 to move toward the second sidewalls 22. Conversely, they move away from the second sidewalls 22.
[0023] like Figures 7-8As shown, specifically, the first connecting block 31 has an upwardly inclined first slope 313 on its upper side and a downwardly inclined second slope 314 on its lower side. The second connecting block 32 has a third slope 321 on its lower side that matches the first slope 313. The third slope 321 is wedge-fitted onto the first slope 313. The third connecting block 33 has a fourth slope 331 on its upper side that matches the second slope 314. The fourth slope 331 is wedge-fitted onto the second slope 314.
[0024] like Figures 5-6 As shown, specifically, the second connecting block 32 is provided with a first strip hole 323 along its sliding direction. The second connecting block 32 is screwed onto the first inclined surface 313 after the first bolt 324 passes through the first strip hole 323, so as to lock the second connecting block 32 onto the first connecting block 31 and prevent the second connecting block 32 from falling off the first connecting block 31. When the second connecting block 32 slides obliquely on the first connecting block 31, the first bolt 324 can guide the sliding of the second connecting block 32 and prevent the first bolt 324 from hindering the oblique sliding of the second connecting block 32. The third connecting block 33 is provided with a second strip-shaped hole 333 along its sliding direction. The third connecting block 33 is screwed onto the second inclined surface 314 after the second bolt 334 passes through the second strip-shaped hole 333, so as to lock the third connecting block 33 onto the first connecting block 31 and prevent the third connecting block 33 from falling off the first connecting block 31. When the third connecting block 33 slides obliquely on the first connecting block 31, the second bolt 334 can guide the sliding of the third connecting block 33 and prevent the second bolt 334 from obstructing the sliding of the third connecting block 33.
[0025] Furthermore, the first strip-shaped hole 323 has a first countersunk hole 322. The inclination direction of the bottom of the first countersunk hole 322 is consistent with the sliding direction of the second connecting block 32. The screw of the first bolt 324 passes through the first strip-shaped hole 323 and is screwed onto the first inclined surface 313. The head of the first bolt 324 is located inside the first countersunk hole 322, which can prevent the head of the first bolt 324 from protruding from the second connecting block 32, thus saving space. Similarly, the second strip-shaped hole 333 has a second countersunk hole 332. The inclination direction of the bottom of the second countersunk hole 332 is consistent with the sliding direction of the third connecting block 33. The screw of the second bolt 324 passes through the second strip-shaped hole 333 and is screwed onto the second inclined surface 314. The head of the second screw 324 is located inside the second countersunk hole, which can prevent the head of the second bolt 324 from protruding from the third connecting block 33, thus saving space.
[0026] Preferably, the cross-section of the first connecting block 31 is an isosceles trapezoid, with the upper base of the first connecting block 31 facing the second side wall 22, and the two sides of the first connecting block 31 facing the first side wall 21 and the third side wall 23 respectively. The cross-sections of the second connecting block 32 and the third connecting block 33 are right triangles. The hypotenuse of the second connecting block 32 is wedge-fitted onto the side of the first connecting block 31 facing the first side wall 21, and the hypotenuse of the third connecting block 33 is wedge-fitted onto the side of the first connecting block 31 facing the third side wall 23.
[0027] Preferably, the connector 20 is tubular; further, the cross-section of the tubular connector 20 is rectangular, the top wall of the tubular connector 20 is the first side wall 21, the bottom wall of the tubular connector 20 is the third side wall 23, and any side wall adjacent to the top wall of the tubular connector 20 is the second side wall 22.
[0028] like Figure 9 , Figure 10 As shown, in other embodiments, the first sidewall 21 and the second sidewall 22 can form a "T" shape or an inverted "L" shape. In these embodiments, it is not necessary to set a third connecting block 33. It is sufficient for the first connecting block 31 and the second connecting block 32 to form the above-mentioned fit.
[0029] The directional terms used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.
[0030] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
