Description

Technical Field

[0001] The present invention relates to a supporting device and a supported object comprising the supporting device. Background Art

[0002] In practice, supporting objects such as display cabinets, furniture, air compressors, engines, and the bases of large mechanical equipment often need to be repositioned as needed. However, due to the relatively large size of these supporting objects, they are very inconvenient to move and transport. Therefore, in order to facilitate movement and transportation, rolling components such as universal wheels are usually set at the bottom of the supporting objects. When moving, the staff pushes the supporting objects to move to the target position under the action of the universal wheels, which greatly improves the movement efficiency of the supporting objects and saves the physical strength of the staff. However, since universal wheels are easy to roll, supporting objects with only universal wheels will move and cannot be positioned at the predetermined position, resulting in poor stability, which makes the equipment prone to oscillation during operation, affecting the service life of the equipment and making it difficult to ensure the safety of items on the supporting objects.

[0003] To this end, universal wheels are often equipped with foot brakes that lock the wheels, thereby securing the supported object in a predetermined position. However, because the orientation of the universal wheel is uncertain and easily shifted, the foot brakes offer low locking efficiency and stability, making them susceptible to slight movement. Furthermore, these foot brakes impose higher requirements on the surface and slope of the caster, which can limit its use and further reduce locking efficiency. Summary of the Invention

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the following embodiments and accompanying drawings specifically illustrate the support device of the present invention and the supported object including the support device.

[0027] Figure 1 is a schematic diagram of the three-dimensional structure of the supporting device in an initial state in an embodiment of the present invention; Figure 2 It is a schematic diagram of the exploded installation of the supporting device in an embodiment of the present invention.

[0028] like Figure 1 and Figure 2 As shown, in this embodiment, the support device 100 is installed at the bottom of a movable support object, such as a display cabinet, furniture, an air compressor, an engine, or the base of a large mechanical device, to support and secure the support object. The support device 100 includes a housing 10, a support rod 20, a pressing portion 30, a locking portion 40, and a support rod reset assembly 50.

[0029] like Figure 1 and Figure 2 As shown, the housing base 10 is a rectangular parallelepiped shell formed from welded metal sheets, and is used to mount the support rod 20, pressing portion 30, locking portion 40, and support rod reset assembly 50 on a supported object. An operating opening 11 is provided on the side of the housing base 10, and an upper through hole 12 and a lower through hole (not shown) are provided on the top and bottom walls of the housing base 10, respectively, to match and correspond to the support rod 20. In this embodiment, a mounting plate 13 is provided in the middle of the exterior of the housing base 10 for mounting the housing base 10 on the supported object.

[0030] Figure 3is a structural schematic diagram of the supporting device in an initial state in an embodiment of the present invention;

[0031] Figure 4 It is a structural schematic diagram of an embodiment of the present invention in which the supporting device is in a state of first pressing and the pushing member and the pressing component have not yet been reset.

[0032] like Figures 1 to 4 As shown, the support rod 20 is a vertically arranged straight metal rod, movably inserted into the housing 10 by sequentially passing through the upper and lower through-holes 12. The upper end of the support rod 20 extends upward through the upper through-hole 12 to form an upper protruding end 20a, while the lower end extends downward through the lower through-hole to form a lower protruding end 20b. In this embodiment, the lower protruding end 20 is provided with a disc-shaped support seat 21 to increase the contact area with the ground and thus enhance support stability. The middle portion of the support rod 20 is provided with mounting holes 22 arranged radially along the rod.

[0033] like Figures 1 to 4 As shown, the pressing portion 30 is correspondingly provided at the operation opening 11 for engaging with the support rod 20 and causing the support rod 20 to move downward relative to the housing base 10. The pressing portion 30 includes a push member 31, a pressing and restoring member 32, a limiting plate 33 and a pressing component 34.

[0034] The pushing member 31 is a rectangular plate-like body that matches the operating opening 11. The plate-like body has two side ends. One side end extends into the shell base 10 through the operating opening 11 and is provided with a through hole 31a that matches the support rod 20. The pushing member 31 is movably connected to the outside of the support rod 20 through the through hole 31a; the other end is located outside the shell base 10 and is connected to the pressing component 34 so as to be pressed by the pressing component 34.

[0035] The pressing and restoring member 32 is used to reset the pushing member 31 and the pressing component 34 , and an upper end thereof is connected to a lower surface of one side end of the pushing member 31 extending into the housing 10 .

[0036] The limiting plate 33 is used to limit the pressing and restoring member 32. It is fixedly arranged in the housing 10 and connected to the lower end of the pressing and restoring member 32. The limiting plate 33 has a shape that matches the housing 10. The central portion is provided with a through hole 33a that matches the support rod 20 and is used for the support rod 20 to pass through.

[0037] In this embodiment, the pressing and restoring member 32 is a coil spring that is sleeved on the outside of the support rod 20, with its upper and lower ends respectively contacting the lower surface of the push member 31 and the limit plate 33. Of course, depending on actual needs, the pressing and restoring member 32 can also be made of other elastic elements such as a rubber elastic tube.

[0038] The pressing member 34 is used to press downward on the other end of the push member 31 located outside the housing 10, causing the push member 31 to flip relative to the support rod 20 with the upper end of the pressing and restoring member 32 as a fulcrum, so that the wall of the push through hole 31a contacts the outer surface of the support rod 20, further driving the support rod 20 to move downward. The pressing member 33 includes a pressing member 341 and a transmission member 342.

[0039] The pressing member 341 is a shaped frame made of sheet metal, with an open end and a closed end. The open end is rotatably connected to the two side walls of the housing 10 via a rotating shaft 341a. The closed end serves as the pressing end, equipped with a connecting sleeve 341b for inserting an external pressing handle to drive the pressing member 314 downward rotation.

[0040] The transmission member 342 is fixedly mounted on the pressing member 341 and connected to the upper surface of the other end of the push member 31. In this embodiment, the transmission member 342 is a straight rod that contacts the upper surface of the push member 31 and has its ends fixedly connected to the two sides of the yoke that serves as the pressing member 341.

[0041] like Figure 1 As shown, the locking portion 40 is provided above the housing base 10 for combining with the support rod 20 and locking the support rod 20 in a position when the support rod 20 has completed its downward movement. The locking portion 40 comprises a rotating shaft 41, a locking member 42 and an elastic positioning member 43.

[0042] The rotating shaft 41 is arranged horizontally, and the middle portion is fixed to the top wall of the housing base 10 via a rotating shaft mounting rod 41 a.

[0043] The locking member 42 is a rectangular plate-like body having two side ends. One side end is provided with a through hole 42a that matches the support rod 20 and a notch 42b that matches the shaft mounting rod 41a. The locking member 42 is movably sleeved on the outside of the upper protruding end 20a of the support rod 20 through the through hole 42a. At the same time, the shaft mounting rod 41a is inserted into the notch 42b and the upper surface of the side end of the locking member 42 contacts the shaft 41, thereby enabling the locking member 42 to rotate up and down relative to the housing 20 about the locking pivot 41, that is, the locking member 42 can be flipped relative to the support rod 20; the other side end is a lock release pressing end.

[0044] The upper and lower ends of the elastic positioning member 43 abut against the lower surface of the locking member 42 and the top wall of the housing 10, respectively. This allows the locking member 42 to rotate upward about the rotation axis 41 under the resilient force of the elastic positioning member 43, i.e., to flip upward relative to the support rod 20, allowing the wall of the through hole 42 to abut against the outer surface of the support rod 20, thereby locking the support rod 20. In this embodiment, the elastic positioning member 43 is a coil spring that is sleeved onto the exterior of the upper protruding end portion 20a of the support rod 20. Of course, depending on actual needs, the press-reset member 32 may also be a rubber elastic tube or other elastic element.

[0045] like Figures 1 to 4 As shown, the support rod reset assembly 50 is disposed in the housing 10 and below the reset member limit plate 33, and is used to be combined with the support rod 20 and reset the support rod 20 when the locking portion 40 releases the lock on the support rod 20. The support rod reset assembly 50 includes a support rod reset member 51 and a limit member, wherein the limit member has a limit ring 52 and a limit shaft 53.

[0046] The support rod reset member 51 is used to reset the support rod 20. Its lower end abuts the bottom wall of the housing 10, and its upper end is connected to the middle portion of the support rod 20 via a stopper. In this embodiment, the support rod reset member 51 is a coil spring that is sleeved around the outside of the support rod 20. Of course, other elastic elements such as a rubber elastic tube may also be used for the support rod reset member 51, depending on actual needs.

[0047] The limiting ring 52 is sleeved on the outside of the support rod 20, and the bottom thereof abuts against the upper end of the support rod reset member 51.

[0048] The limiting shaft 53 is inserted into the mounting hole 22 of the support rod 20, with both ends extending out of the ends of the mounting hole 22 and contacting the top of the limiting ring 52, thereby limiting the position of the limiting ring 52. In this embodiment, the limiting ring and the limiting shaft are combined to limit the position of the support rod reset member, which has a simple structure, is easy to assemble and disassemble, and is low in cost.

[0049] Figure 5 2 is a schematic structural diagram of the supporting device in an embodiment of the present invention in a state where the pressing component is pressing for the first time and the pushing member and the pressing component are reset; Figure 6 It is a structural schematic diagram of an embodiment of the present invention in which the support device is in a state where the maximum support height is reached after being pressed multiple times by a pressing component.

[0050] In this embodiment, if Figures 3 to 6 As shown, the use process of the supporting device 100 is as follows:

[0051] During operation, the external pressing handle is inserted into the connecting sleeve 341b on the pressing member 341 and pressed to rotate the pressing member 341 downward, and then the transmission member 342 presses the push member 31, so that the push member 31 flips with the upper end of the pressing and restoring member 32 as the fulcrum, so that the hole wall of the through hole 31a contacts the outer surface of the support rod 20, generating a downward friction force, and then relying on this downward friction force to further drive the support rod 20 to move downward. At this time, the pressing and restoring member 32 is in a compressed state, as shown in FIG. Figure 4 .

[0052] Release the external pressing handle, and the pushing member 31 begins to move upward under the rebound force of the pressing and restoring member 32, so that the hole wall of the through hole 31a is out of contact with the outer surface of the support rod 20, and then further push the pushing member 31 upward, thereby restoring the pushing member 31 and the pressing member 341 to their initial state. Figure 5 At the same time, the locking member 42, under the rebound force of the elastic positioning member 43, keeps the hole wall of the through hole 42a and the outer surface of the support rod 20 in abutment at all times, thereby locking the support rod 20 in the position at which it completed the first downward movement. At this point, one pressing operation is completed.

[0053] Repeat the pressing operation several times until the support base 21 at the lower end of the support rod 20 touches the ground. Figure 6 shown.

[0054] When not in operation, the other side end of the locking member 42 away from the rotating shaft 41 (i.e., the lock release pressing end) is pressed, so that the hole wall of the through hole 42a is disengaged from the outer surface of the support rod 20, that is, the locking member 42 releases the lock on the support rod 20. At this time, the support rod 20 moves upward under the rebound force of the support rod restoring member 51 in the compressed state, and finally returns to the position as shown in FIG. Figure 3 The initial state is shown.

[0055] Functions and Effects of the Embodiments

[0056] According to the support device involved in this embodiment and the supported object including the support device, since one side end of the push member is provided with a push through hole that can be movably sleeved on the outside of the support rod, the pressing and resetting member is connected to the lower surface of the push member. When the pressing member presses down on the other side end of the push member, the push member can be flipped relative to the support rod so that the hole wall of the push through hole abuts against the outer surface of the support rod and further pushes the support rod to move. When the support rod is completed to move, the locking part can lock the support rod in the position when the movement is completed, and at the same time, the pressing member releases the pressure on the push member, and the push through hole The hole wall and the outer surface of the support rod are disengaged from the abutment, and the pressing and resetting component resets the pushing component and the pressing component to perform the next pressing operation. Therefore, the support device of this embodiment has a simple structure and is easy to operate. It only needs to press the pressing component at least once to make the support rod move downward continuously and then quickly abut against the ground, so as to firmly position the supported object at a predetermined position, avoiding the problem of low stability after locking due to uncertain direction of the universal wheel in the prior art, improving the stability of the equipment, reducing the vibration of the equipment during operation, extending the service life of the equipment, and reducing the noise generated by vibration.

[0057] In addition, because the locking part has a locking member and an elastic positioning member, the locking member is provided with a locking through hole that can be movably sleeved on the outside of the upper protruding end portion, and the upper and lower ends of the elastic positioning member are respectively abutted against the lower surface of the locking member and the top wall of the shell seat, so that the locking member is flipped relative to the support rod so that the hole wall of the locking through hole and the outer surface of the support rod are always abutted. Therefore, on the one hand, the locking part in this embodiment can quickly lock the support rod; on the other hand, the support rod can be easily unlocked by simply pressing the locking member.

[0058] Furthermore, because the locking portion also includes a rotating shaft, which is arranged horizontally, the upper surface of one side end of the locking member is in contact with the rotating shaft, and the other side end is used as a lock release pressing end. By pressing the lock release pressing end, the locking member can easily release the lock on the support rod.

[0059] In addition, because it also has a support rod reset assembly, the support rod reset assembly has a support rod reset component and a limiting component. The lower end of the support rod reset component abuts against the bottom wall of the shell seat, and the upper end abuts against the support rod through the limiting component, which can achieve rapid reset of the support rod when the locking part is unlocked. It has a simple structure, is easy to assemble and disassemble, is easy to purchase and manufacture, and has a low cost.

[0060] The above embodiments are preferred examples of the present invention and are not intended to limit the scope of protection of the present invention.
