Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

The utility model provides a furniture supporting device which at least comprises a height adjusting assembly, a supporting assembly and a supporting platform.

The support assembly at least comprises an elastic support unit and at least two linkage units which can be extended or folded. Under the condition that the furniture body is arranged on the supporting platform, the at least two linkage units respectively expand outwards to enlarge the supporting range of the supporting platform based on the elastic deformation of the elastic supporting unit in the vertical direction. Each linkage unit has a support point. When the linkage unit is unfolded outwards, the supporting points move outwards and gradually share the pressure of the furniture, so that the pressure of the furniture is not limited in the middle of the supporting platform, but the supporting points are dispersed in a temporary supporting line mode, the supporting force of the supporting platform in such an area is not concentrated, the supporting points are uniformly distributed, and the deformation of the supporting platform is favorably avoided.

The support assembly can be provided with at least two support points to support furniture, and preferably supports the furniture through three support points, so that the support force of the support platform is uniformly distributed, and the periphery of the support platform is not easy to deform in a curved surface.

Preferably, as shown in fig. 3, the lateral surface of the support platform is provided with three levels distributed according to a regular triangle. The first level 31, the second level 32 and the third level 33 are connected to form a regular triangle. And under the condition that the three gradienters are all in the horizontal state, the supporting platform is in the horizontal state. The three gradienters form a triangle, and the plane where the three gradienters are located is the plane where the supporting platform is located. When all three gradienters are in the horizontal state, the support platform is in the horizontal plane. When one of the gradienters is not in a horizontal state, the support platform is bent, and the support platform needs to be replaced. Compared with the arrangement mode of a single level instrument in the prior art, the level instruments distributed in a triangular shape can really display whether the whole supporting platform is in a horizontal state or not, and workers can conveniently monitor whether the supporting platform is deformed or not.

Preferably, as shown in fig. 1, 2 and 5, the elastic support unit at least comprises a force bearing block 18, a first support seat 4, a second support seat 9 and at least one elastic element 8. The resilient member is preferably a spring. The elastic member 8 is disposed between the first support seat 4 and the second support seat 9. The first support 4 is higher than the second support 9 in the vertical direction. The force-receiving block 18 is arranged on the first support 4 and can extend through the support platform 2 through a hole in the centre of the support platform 2. Wherein, under the condition that the furniture body is not arranged, the stress block 18 protrudes out of the horizontal plane of the supporting platform. The stress block has the effect that the force part originally applied to the supporting platform by the furniture is applied to the elastic supporting unit, so that the strength of the force borne by the supporting platform is reduced. The central part of the supporting platform is not stressed, and the peripheral part of the hole is uniformly supported by the linkage unit, so that the supporting platform is not easy to deform.

According to the utility model, the holes are arranged on the supporting platform, and partial supporting force is directly provided for the furniture through the stress block of the supporting component, so that the pressure of the furniture on the supporting platform is reduced, the deformation probability of the supporting platform is further reduced, and the service life of the supporting platform is prolonged.

Preferably, a limiting rod 7 is further disposed on a surface of the first supporting seat 4 opposite to the second supporting seat 9. The stopper rod 7 may be provided inside the elastic member or may be provided outside the elastic member in a hollow manner. The stopper rod 7 is parallel to the elastic member 8 in the vertical direction. Under the condition that the furniture body is not arranged, the limiting rod 7 is in a suspended state relative to the second supporting seat 9 based on the action of the elastic piece 8. Under the condition of arranging the furniture body, the first supporting seat 4 moves downwards based on the force applied by the furniture body to the stress block 18, and the limiting rod 7 is in contact with the second supporting seat 9 based on the pressure born by the stress block 18 so as to support the elastic supporting unit to perform limited deformation.

Preferably, a pillar is disposed between the first supporting seat 4 and the second supporting seat 9, and supports the first supporting seat 4 and the second supporting seat 9 in a vertical direction. The pillar penetrates the second support base 9 and is movable in the vertical direction. The limiting rod 7 penetrates through the support column, one end of the limiting rod is fixedly connected with the first support seat 4, and the other end of the limiting rod is suspended in the vertical direction. Under the condition of arranging the strut, under the condition of arranging the furniture body, the first supporting seat 4 moves downwards based on the force applied by the furniture body to the stress block 18, the elastic piece 8 is compressed, and the strut penetrates through the second supporting seat 9 and further moves downwards until the limiting rod 7 is contacted with the second supporting seat 9 and supports the first supporting seat 4, so that the first supporting seat 4 is prevented from moving downwards continuously. Through setting up the bracing piece for the elastic component carries out elastic deformation in limited range, thereby has restricted linkage unit's expansion range.

Preferably, the linkage unit includes a support rod 5 and an extension rod 6. One end of the support rod 5 is rotatably connected to the first support base 4. One end of the support rod 5 is rotatably connected with the middle part of the expansion rod 6. One end of the extension rod 6 is rotatably connected to the second support 9. One end of the extension rod 6 is slidably connected to the support platform 2. In the utility model, the rotatable connection mode is a hinge joint.

The linkage unit can expand based on the pressure of the furniture body, so that the supporting point moves and supports along a linear track. Particularly, in the process of linear movement of the supporting point, the unfixed movement of the supporting point reduces the time for applying pressure on the supporting platform at a single position, thereby reducing the deformation probability of the supporting platform around the hole.

Preferably, in the case where the three link units are unfolded, the three link units are arranged in such a manner that the angle angles therebetween are the same. The three linkage units are arranged, so that the supporting platform can be prevented from tilting, and the supporting stability of the supporting platform is improved.

The number of linkage units of the present invention may also be four, five or even more. Compared with the defect that the support platform is prone to lateral tilting deformation due to the fact that the two linkage units are arranged, the three linkage units are arranged to enable the support platform to be stressed stably and uniformly, and the defect that the lateral tilting deformation is caused is overcome.

Preferably, the end of the extension rod 6 that slides opposite the support platform 2 is provided with a rotatable slide 17. The slide 17 slides along the slide rails of the support platform to support the extension rod 6 in extension and/or retraction. The setting of slider for the extension rod slides in the slide rail and does not receive the influence of extension rod angle change. The setting of slider and slide rail can reduce the resistance of linkage unit's expansion for the linkage unit expandes fast and realizes stable support.

Preferably, as shown in fig. 4, the three sliding rails are distributed in a uniformly distributed radial manner centering on the hole in the center of the supporting platform 2. And the extension line of the axis of the slide rail points to the corresponding level. The slide rail so sets up for the plane that three spirit level constitutes all is the horizontality with the plane at slide rail place, has reduced the probability that the support plane warp. The radial slide rail can reduce the probability of damage to the surface of the platform formed by the fact that the linkage unit directly applies force to the surface of the supporting platform, meanwhile, the slide rail is not easy to deform, the slide rail can support the supporting platform in a line with a larger range due to the support of the slide block, and the supporting platform further has the advantage of uniform stress.

Preferably, in case the furniture body is removed from the support platform, the first support seat 4 is displaced upon the return of the first elastic element 8 and pulls the extension rod 6 towards the elastic support unit by means of the support rod 5. After the furniture is installed, the supporting platform can be automatically lifted and reset, and the supporting range of the supporting point is reduced.

Preferably, the height adjusting assembly at least comprises a telescopic rod 10 and a receiving column 11, a rotating mechanism formed by a bearing and a rotating shaft in a combined manner is arranged in the receiving column 11, and the telescopic rod 10 is lifted or lowered based on the rotation of the bearing and the rotating shaft. The height adjusting assembly is beneficial to lifting the furniture to the required height, and the working difficulty of workers is reduced.

Specifically, as shown in fig. 6, a fixing plate 105 is fixedly mounted to the bottom end of the receiving column 11.

The bottom of the inner wall of one side of the receiving column 11 is rotatably connected with one end of the rotating shaft 107 through a bearing. The other end of the rotating shaft 107 passes through the other side of the receiving column and is connected with one end of the adjusting handle 12 in a clamping manner. The middle part of the rotating shaft 107 is fixedly provided with a first bevel gear 112. The first bevel gear 112 is engaged with the second bevel gear 113. The second bevel gear 113 is fixedly installed at the bottom of the screw 114. The bottom end of the screw rod 114 is rotatably connected with the inner wall of the bottom end of the containing column through a bearing. The screw 114 is in threaded connection with a screw nut 116 fixedly arranged in the middle of the top end of the support plate 115. The top end of the supporting plate 115 is fixedly provided with an expansion link 10. The two sides of the inner wall of the bottom end of the storage column are connected with the support plate 115 in an inserting mode through the inserting rods 117.

Two clamping columns 108 are fixedly arranged at the other end of the rotating shaft 107. One end of the adjusting handle 12 is fixedly provided with a connecting cylinder. U-shaped grooves are formed in two sides of one end of the connecting cylinder. The U-shaped groove is connected with the clamping column 108 in a clamping mode. The top end of the screw 114 is fixedly provided with a stop block 118.

The working principle of the utility model is as follows:

the staff places the furniture body on the support platform. The stress block in the center of the supporting platform moves downwards under the pressure of the furniture. The downward movement of the stress block drives the downward movement of the first supporting seat and the limiting rod 7, and the first supporting seat compresses the elastic part 8. During the downward movement of the first support base, the support rod 5 moves adaptively and pushes the expansion rod 6 to expand outward. At this time, the slider at one end of the extension rod 6 moves along the slide rail. When the limiting rod 7 is contacted with the second supporting seat 9, the limiting rod 7 prevents the first supporting seat from moving downwards and starts to bear pressure. At this time, the limiting rod 7, the elastic piece 8 and the support column support the pressure borne by the stress block together, and the overall pressure value borne by the supporting platform is reduced. At the moment, the three linkage units are bought and unfolded simultaneously, and the linkage units can stably support the supporting platform in an approximately triangular structure on the vertical surface. At the same time, the three levels of the support platform should all be in a horizontal position so that the furniture body is on a horizontal plane. The staff rotates the regulation handle, rises the furniture body to required height.

After the furniture is installed, the first supporting seat 4 starts to move up based on the elastic restoration of the first elastic member 8. The first supporting seat 4 pulls the extension rod 6 to be folded towards the elastic supporting unit through the supporting rod 5. The supporting platform can be automatically lifted and reset, and the supporting range of the supporting points is reduced. The staff rotates the regulation handle, reduces the furniture body to minimum height.

It should be noted that the above-mentioned embodiments are exemplary, and that those skilled in the art, having benefit of the present disclosure, may devise various arrangements that are within the scope of the present disclosure and that fall within the scope of the utility model. It should be understood by those skilled in the art that the present specification and figures are illustrative only and are not limiting upon the claims.
