[0021] The present application will be further described in detail below with reference to the accompanying drawings.
[0022] In order to more clearly understand the technical solutions shown in the embodiments of the present application, first, the existing furniture and the possible conditions suffered in the process of carrying the furniture are simply introduced.
[0023] In the prior art, the furniture made of non-wood is generally made of synthetic plate materials, such as Figure 1As shown, the synthetic board generally includes an intermediate layer and rubber skins arranged on both sides of the intermediate layer, the intermediate layer is generally a non-wood wood board product such as pressed wood board, shaving board or particle board, and the rubber skins are bonded on both sides of the intermediate layer by adhesive means. Of course, the aforementioned rubber skin is commonly known as, which generally includes pressure glue, plastic, stickers, etc. Due to cost constraints, furniture generally does not perform comprehensive coating of rubber skin, and the end face of the bottom of the furniture can see the end face of the rubber skin and the intermediate layer.
[0024] During the process of furniture moving, it is inevitable to be collided. The aforementioned collision generally includes mechanical collision formed by external components directly touching the moving furniture, and also includes collision between the bottom of the furniture and the transportation device caused by the overturning moment of the bottom of the furniture. The rubber skin coated on the outside of the furniture has good anti-collision performance. When the external components directly collide with the front of the rubber skin, the furniture generally will not be damaged. However, when the bottom of the furniture collides with the transportation device due to the overturning moment of the bottom of the furniture, it is extremely likely to cause the rubber skin on the bottom of the furniture to fall off, and further cause the furniture to be damaged. The above scenario can be understood through the following Figure 2
[0025] In order to solve the above technical problems, the embodiment of the present application provides a kind of anti-collision furniture moving equipment, please refer to the drawings of the present application Figure 4 Including flat car 10, flat car 10 includes bearing flat plate 11 and a group of directional wheels and a group of universal wheels installed at the bottom of bearing flat plate 11;

[0027] Two V-shaped pieces 22 are movably connected in long hole 21, V-shaped piece 22 includes rotating shaft 23 and upper contact piece 24 and lower contact piece 25 installed on rotating shaft 23, upper contact piece 24 and lower contact piece 25 have an included angle therebetween, so that V-shaped piece 22 has an included angle, lower contact piece 25 is at the bottom of upper contact piece 24, lower contact piece 25, the bottom of upper contact piece 24 and rotating shaft 23 are inside long hole 21, rotating shaft 23 is hinged to limiter 20, two V-shaped pieces 22 are symmetrically distributed, and the opening direction of the included angle of two V-shaped pieces 22 is opposite. When the distance between two lower contact pieces 25 in the same limiter 20 increases, two upper contact pieces 24 have a tendency to approach each other. The end of upper contact piece 24 and lower contact piece 25 away from rotating shaft 23 is fixedly connected with elastic body 26;
[0028] The central axis of rotating shaft 23, the central axis of limiter 20, the central axis of long hole 21 and the advancing direction of directional wheel of flat car 10 are parallel to each other.
[0029] The following will be further described in combination with a specific use scenario.
[0030] In use, the operator moves the flatbed truck 10 to a designated loading location, and then places the furniture on the top base of the carrying flatbed 11, at which time the support plate of the furniture is ensured to be placed in at least two long holes 21 in the middle of the two limiting bodies 20.
[0031] When the support plate or the bearing plate of the furniture is vertically inserted into the long hole 21, the bottom of the bearing plate first contacts the lower contact pieces 25 of the two V-shaped pieces 22, so that the distance between the two lower contact pieces 25 is increased, and after the bottom of the support plate passes through the lower contact pieces 25, the elastic bodies 26 of the two upper contact pieces 24 are respectively tightly attached to the two sides of the support plate away from the one end of the rotating shaft 23, and the elastic bodies 26 of the two lower contact pieces 25 also tightly contact the two sides of the support plate, and after the bottom of the support plate contacts the top base of the carrying flatbed 11, the placement of the furniture is completed, at which time the elastic bodies 26 on the upper contact pieces 24 and the lower contact pieces 25 of the V-shaped pieces 22 are all in contact with the support plate of the furniture, and the elastic bodies 26 are elastically deformed to form a frictional connection with the support plate.
[0032] In the process of moving the device, the wheels at the bottom of the flatbed truck 10 roll on the ground to realize the movement of the carrying flatbed 11, and the movement trajectory of the flatbed truck 10 is mostly a straight line, and the straight movement of the flatbed truck 10 is generally constrained by the direction of the travel direction of the directional wheels, and in the embodiment of the present application, the central axis of the rotating shaft 23, the central axis of the limiting body 20, the central axis of the long hole 21, and the travel direction of the directional wheels of the flatbed truck 10 are parallel to each other, that is, the two side planes of the support plate of the furniture being moved are parallel to the travel direction of the directional wheels of the flatbed truck 10, and when the flatbed truck 10 suddenly stops or the top of the furniture is subjected to a collision, an overturning moment occurs at the bottom of the furniture, at which time, due to the frictional force generated by the two elastic bodies 26 on the V-shaped pieces 22 tightly contacting the two sides of the support plate of the furniture, the aforementioned frictional force can resist the overturning moment, thereby avoiding the furniture from shaking, and avoiding the collision between the bottom of the furniture and the top base of the carrying flatbed 11, thereby avoiding the peeling of the rubber and the middle layer at the bottom of the furniture.
[0033] In general, the embodiment of the present application adopts the symmetrically arranged V-shaped pieces 22 to make the support plate of the furniture tightly contact the symmetrically arranged V-shaped pieces 22 to generate a frictional force during the movement of the furniture, so as to resist the overturning moment of the furniture and avoid the rubber and the middle layer at the bottom of the furniture from peeling due to the violent collision between the bottom of the furniture and the carrying flatbed 11.
[0034] In some possible implementation manners of the embodiments of the present application, the rotating shaft 23 of the V-shaped piece 22 can be sleeved with a shaft sleeve at both ends, the outer side of the shaft sleeve extends out a fixed part, the end of the fixed part away from the shaft sleeve is fixedly connected with the limiting body 20, thereby realizing the hinging of the rotating shaft 23 and the limiting body 20, a first elastic sheet 27 for making the lower contact sheet 25 away from the inner wall of the long hole 21 is mounted on the inner wall of the long hole 21, the end of the first elastic sheet 27 away from the inner wall of the long hole 21 is in contact with the lower contact sheet 25, through the setting of the elastic sheet, the lower contact sheet 25 is away from the long hole 21 in the non-working condition, thereby making the upper contact sheets 24 of the two V-shaped pieces 22 in the same long hole 21 open, facilitating the entering of the furniture support plate, on this basis, a second elastic sheet 28 is mounted between the upper contact sheet 24 and the lower contact sheet 25, the two ends of the second elastic sheet 28 are arranged on the upper contact sheet 24 and the lower contact sheet 25 respectively, when the second elastic sheet 28 restores the deformation, the upper contact sheet 24 and the lower contact sheet 25 are close to each other, the upper contact sheet 24 and the lower contact sheet 25 are rotationally connected on the rotating shaft 23, under the action of the second elastic sheet 28, the elastic body 26 on the upper contact sheet 24 and the lower contact sheet 25 can exert sufficient normal pressure on the furniture side plate, thereby generating sufficient friction force to resist the overturning moment of the furniture.
[0035] In some possible implementation manners of the embodiments of the present application, the top of the bearing flat plate 11 is provided with a plurality of avoiding grooves 12, the plurality of avoiding grooves 12 are arranged at both ends of the limiting body 20, when the friction force between the V-shaped piece 22 in the same long hole 21 and the furniture support plate is insufficient to overcome the overturning moment of the furniture, the setting of the avoiding grooves 12 can provide avoiding space for the furniture rocking fulcrum, avoiding that the pressure intensity of the furniture support plate bottom on the bearing flat plate 11 is too large to cause the rubber of the support plate to fall off, the included angle between the inner cavity bottom of the avoiding groove 12 and the top base surface of the bearing flat plate 11 is an acute angle, the distance from the inner cavity bottom of the avoiding groove 12 to the top base surface of the bearing flat plate 11 gradually increases in the direction from one end of the limiting body 20 to the other end of the limiting body 20, the gradually sinking avoiding groove 12 can fit the bottom of the support plate when the furniture shakes, increasing the support area of the support plate bottom, thereby reducing the pressure intensity of the support plate bottom on the bearing flat plate 11, avoiding that the pressure intensity of the furniture support plate bottom on the bearing flat plate 11 is too large to cause the rubber of the support plate to fall off, on this basis, the intersection between the inner cavity bottom of the avoiding groove 12 and the top of the bearing flat plate 11 is provided with a buffer pad 13, through the flexible buffering of the buffer pad 13, the rubber of the furniture support plate bottom is further avoided from falling off.
