Referring to fig. 2, the body 20 may have a housing 21, the housing 21 is used for disposing various components of the adjustable base device 10, and the housing 21 may be configured in various shapes, for example, in this embodiment, the housing 21 of the body 20 is configured as a substantially rectangular frame structure, and the supporting base 30 is installed at the bottom of the housing 21 and may partially extend into the housing 21.

Specifically, the body 20 is provided with a mounting portion, which may be located inside the housing 21 or outside the housing 21, in this embodiment, the housing 21 includes a bottom plate 211, a top plate 212, and a side plate 213, the side plate 213 is connected between the bottom plate 211 and the top plate 212, and the bottom plate 211 and the top plate 212 are disposed opposite to each other. The mounting part is provided to the bottom plate 211 and is positioned at an edge portion of the bottom plate 211 adjacent to the side plate 213. In this embodiment, the mounting portion is provided with a threaded hole 214, the threaded hole 214 penetrates through the bottom plate 211, an internal thread is provided in the threaded hole 214, meanwhile, the side plate 213 is provided with an exposure hole 215, and the exposure hole 215 is located at a position adjacent to the mounting portion. In other embodiments, the mounting portion may also be provided with a built-in nut, the built-in nut forms a threaded hole, and the bottom plate 211 may be provided with a through hole to communicate with the threaded hole of the built-in nut, and the threaded hole is used for assembling the supporting base 30.

Referring to fig. 3 and 4, the supporting base 30 is assembled to the mounting portion, the supporting base 30 includes a screw 310, a supporting foot 320, a fixing portion 330 and an adjusting knob 340, the screw 310 includes a first end 311 and a second end 312 opposite to each other, a first thread is disposed on an outer wall of the screw 310 along a circumferential direction thereof, the first thread is capable of cooperating with the threaded hole 214 and being threadedly engaged with and assembled in the threaded hole 214, the first end 311 of the screw 310 is located outside the housing 21 and is used for connecting the supporting foot 320, and the second end 312 is located inside the housing 21 and is used for connecting the adjusting knob 340.

The support foot 320 is sleeved on the first end 311, and the screw 310 is rotatable relative to the support foot 320, i.e. the support foot 320 and the screw 310 are not fixedly connected. In this embodiment, referring to fig. 5, the support foot 320 is provided with a stepped through hole, and the stepped through hole penetrates through the support foot 320. As an example, in the present embodiment, the small-aperture side of the stepped through-hole faces the body 20, and the large-aperture side of the stepped through-hole faces away from the body 20. Specifically, the support foot 320 includes a support portion 322 and a fixing plate 321, and the support portion 322 is connected to one side surface of the fixing plate 321 to serve as a support of the entire support base 30. The fixing plate 321 is provided with a first through hole 323, and the first through hole 323 penetrates through the fixing plate 321. In this embodiment, the fixing plate 321 includes an outer surface 326 and a stepped surface 325, which are opposite to each other, the supporting portion 322 is connected to the fixing plate 321 at an edge of the fixing plate 321, and extends out toward a side perpendicular to a horizontal direction of the fixing plate 321, so that the stepped surface of the fixing plate 321 and the supporting portion 322 jointly enclose to form a second through hole 324, an aperture of the second through hole 324 is larger than an aperture of the first through hole 323, and the second through hole 324 is communicated with the first through hole 323 and jointly forms a stepped through hole. The first through hole 323 of the fixing plate 321 is for forming a fitting with the first end portion 311. The aperture of the first through hole 323 is slightly larger than the diameter of the first end 311 of the screw 310, so that when the first end 311 is inserted into the first through hole 323, the fixing plate 321 and the first end 311 can rotate relatively. In other embodiments, the supporting portion 322 may not be disposed in a ring shape, and in this case, the supporting portion 322 may be formed by a plurality of independent block structures and disposed on the stepped surface 325 of the fixing plate 321 at intervals.

Referring to fig. 3, 4 and 5, the first end 311 of the screw 310 extends into the stepped through hole and is connected to the supporting foot 320, and specifically, the first end 311 of the screw 310 extends into the first through hole 323 and the second through hole 324 and is connected to the fixing portion 330. Meanwhile, in order to fix the support foot 320 in the extending direction of the screw 310, the diameter of the first end 311 of the screw 310 is smaller than that of the second end 312, so that the peripheral wall of the first end 311 of the screw 310 forms a recessed step 313, and the radial dimension of the step 313 is larger than that of the first through hole 323, so that after the first end 311 extends into the first through hole 323, the step 313 can clamp the fixing plate 321 of the support foot 320 in the extending direction of the screw 310. When assembled, the outer surface 326 of the retainer plate 321 of the support foot 320 rests on the step 313 to position the support foot 320. In other embodiments, an outwardly protruding protrusion may be provided directly on the screw 310 to position the support foot 320, and the step 313 formed in the first end 311 need not be recessed.

In other embodiments, the support feet 320 may be configured as a substantially plate-like structure to increase the contact area when the device is placed, and it is also possible to form a stepped through hole directly in the plate-like structure. In order to increase the stability of the whole body 20 when the supporting foot 320 is placed, a non-slip portion 360 may be further disposed on the bottom surface of the supporting foot 320, which is away from the adjusting knob 340, for example, the non-slip portion 360 is disposed on the end surface of the supporting portion 322, which is away from the fixing plate 321, the non-slip portion 360 may be, for example, sponge, plastic, etc., and by increasing the non-slip portion 360, the friction force when the whole supporting foot 320 is placed may be increased, thereby improving the stability of the body 20.

The fixing portion 330 is disposed at the first end 311 and connected to the support foot 320 to limit the support foot 320 from being separated from the screw 310 along the extending direction of the screw 310. Here, the connection between the fixing portion 330 and the support foot 320 may be a fixed connection, a snap connection, or an abutting connection, and is not limited herein. Specifically, the first end portion 311 extends into the stepped through hole and is connected to the fixing portion 330, and the fixing portion 330 presses the fixing plate 321 of the support foot 320 against the step 313, that is, the fixing plate 321 of the support foot 320 is located between the step 313 and the fixing portion 330, so that the support foot 320 is fixed by the screw 310 and the fixing portion 330 in the extending direction of the screw 310 and cannot be separated from the screw 310.

The fixing portion 330 and the first end portion 311 can be connected in a variety of manners, in this embodiment, the first end portion 311 is provided with a second thread arranged along the circumference of the screw rod 310, the fixing portion 330 includes a first washer 331 and a locking nut 332, the first washer 331 is sleeved on the first end portion 311, the locking nut 332 is screwed on the second thread and supports the first washer 331 against the stepped surface 325, that is, the fixing plate 321 of the support foot 320 is defined between the first washer 331 and the step 313 of the first end portion 311. The first washer 331 may be made of a material having a low coefficient of friction, such as plastic, ceramic, etc.

Because the fixing portion 330 is fixedly connected with the screw 310 through the screw thread, when the screw 310 rotates, the fixing portion 330 rotates along with the screw 310, the first washer 331 is sleeved on the screw 310, and the first washer 331 is relatively smooth and is subjected to a small friction force of the lock nut 332, so that the first washer will not rotate along with the lock nut 332, and will not transmit the rotating friction force to the support foot 320, so that the support foot 320 will not rotate along with the screw 310, which is equivalent to the support foot 320 being disposed between the fixing portion 330 and the step 313 in a floating manner. Therefore, when the screw 310 is adjusted, the support foot 320 moves along the extending direction of the screw 310, but does not rotate along with the rotation of the screw 310.

As an example, the first washer 331 may be a teflon washer made of teflon (Polytetrafluoroethylene, PETE), which has a very low friction coefficient, and can prevent a large relative friction force from being generated between the first washer 331 and the support foot 320, and thus the support foot 320 from rotating with the screw 310. It is understood that in other embodiments, the first washer 331 may be made of other materials with a lower coefficient of friction, such as PE, PP, etc.

In this embodiment, the pitch of the first thread is greater than the pitch of the second thread, which provides the benefit of: due to the larger pitch of the first thread, the screw 310 needs to be rotated by a smaller angle during the movement of the screw 310 in the extending direction thereof when the screw 310 is rotated, which reduces the friction transmitted to the support foot 320 during adjustment and further prevents the support foot 320 from rotating. The pitch of the second thread is smaller, and the locking nut 332 of the fixing part 330 is more stably connected to the screw rod 310 and is not easily separated, so that the support foot 320 is difficult to be separated.

When whole support footing 320 worked, the part of support footing 320 with the contact of step 313 can be born to the weight of organism 20, consequently support footing 320's bearing can not be too concentrated, compares and carries out the bearing in the mode that adopts the screw thread, and structural stability is better, does benefit to increase of service life.

To avoid damage to the support feet 320 due to excessive force, the support feet 320 may be made of a material with greater structural strength, such as metal, carbon fiber, high-strength plastic, etc. In some embodiments, in order to reduce the pressure on the support foot 320, the support base 30 may further include a second washer 333, the second washer 333 is disposed between the step 313 and the support foot 320 and sleeved on the first end 311 of the screw 310, and by disposing the second washer 333, a portion of the weight of the housing 20 may be dispersed, thereby preventing the support foot 320 from being damaged due to insufficient structural strength of the support foot 320, and at this time, the requirement for structural strength of the support foot 320 may be properly reduced, and the support foot 320 may be made of common plastic without worrying about damage. The number of the second gaskets 333 may also be two or more, and in this case, two or more second gaskets 333 may be stacked together. In some embodiments, as shown in fig. 3 and 5, the outer surface 326 of the support foot 320 may form a gasket groove 327, the gasket groove 327 may be used to receive the second gasket 333, the second gasket 333 is sleeved on the first end 311 of the screw 310 and received in the gasket groove 327 during assembly, and the volume of the gasket groove 327 may be adapted to the second gasket 333. It is understood that in other embodiments, the gasket groove 327 may not be provided.

Referring to fig. 3 and 6, the adjusting knob 340 is mounted on the second end 312 and is used for driving the screw rod 310 to rotate, and the adjusting knob 340 is fixedly mounted on the screw rod 310 so that the adjusting knob 340 and the screw rod 310 do not rotate relatively. In this embodiment, the adjustment knob 340 is located in the housing 21, and an outer wall portion of the adjustment knob 340 is exposed from the exposure hole 215, so that a user can operate the portion exposed from the exposure hole 215 to rotate the adjustment knob 340. The adjusting knob 340 is provided with a fixing hole 341 therethrough, and the second end 312 of the screw 310 is inserted into the fixing hole 341 of the adjusting knob 340 to form an assembly and rotate synchronously with the adjusting knob 340. The fixing hole 341 is a stepped hole, the end of the second end 312 of the screw 310 is provided with a flange 314, and the flange 314 can abut against the step 342 of the adjusting knob 340, so that the screw 310 cannot completely penetrate out of the fixing hole 341 towards the direction of the supporting foot 320, and further the movement stroke of the screw 310 can be limited.

The outer wall of the adjustment knob 340 may be configured to be circular, polygonal (such as hexagonal, pentagonal or other polygonal shapes), etc., and is not limited herein, and in this embodiment, the outer wall of the adjustment knob 340 is configured to be hexagonal, so that the user can rotate the adjustment knob 340. Further, in order to increase the friction force of the outer wall of the adjustment knob 340 and prevent the user from slipping when rotating the adjustment knob 340, the outer wall of the adjustment knob 340 may be made of a material having a large friction coefficient, such as a metal material. In addition, the outer wall of the adjusting knob 340 may be provided with a small protrusion or a rib, so as to increase the friction force. Of course, it will be appreciated that other materials for forming the outer wall of the adjustment knob 340 are also possible.

In some embodiments, the supporting base 30 may further include an elastic member 350, the elastic member 350 is disposed in the fixing hole 341, two ends of the elastic member 350 respectively abut against the flange 314 and the step 342 of the adjusting knob 340, by disposing the elastic member 350, the stroke of the screw 310 may be limited, and the screw 310 is reset, and when the screw 310 rotates, the adjusting knob 340 may always abut against the bottom plate 211 without changing its position, so that the adjusting knob 340 may always be exposed from the exposing hole 215, which is convenient for a user to adjust, and in this process, only the screw 310 vertically moves along its extending direction.

In one embodiment, the second end 312 is provided with a first limiting portion, and the adjusting knob 340 is provided with a second limiting portion cooperating with the first limiting portion to limit the relative rotation between the adjusting knob 340 and the screw rod 310, so that when the user rotates the adjusting knob 340, the screw rod 310 rotates together with the adjusting knob 340. In this embodiment, the flange 314 of the screw 310 is configured to be hexagonal and serves as a second limiting portion, the inner wall of the adjusting knob 340 is configured to be hexagonal and to cooperate with the flange 314 to serve as a first limiting portion, when the adjusting knob is assembled, the flange 314 is clamped into the fixing hole 341, and the screw 310 can only move relative to the adjusting knob 340 along the extending direction thereof and cannot rotate relative to the adjusting knob 340. In other embodiments, the first and second limiting parts may be provided in other forms, such as: the first limiting part and the second limiting part are arranged in the form of a clamping groove and a protruding block which can be matched with each other, and the first limiting part and the second limiting part are mutually embedded, so that the aim of preventing the screw 310 and the adjusting knob 340 from rotating relatively can be fulfilled. It should be noted that the structure of the flange 314 shown in the present embodiment is only an example, and in other embodiments, the flange 314 may also be a pentagon or other polygonal structure, or the flange 314 may also be provided with a substantially circular structure, in which case, a protrusion may be provided in the radial direction of the flange 314 as the second stopper, which is not limited herein.

It is understood that in some other embodiments, the first position-limiting portion and/or the second position-limiting portion may not be provided, and the second end 312 of the screw 310 and the adjusting knob 340 may be fixed relative to each other by interference fit, for example.

In the adjustable base apparatus 10 provided in this embodiment, the working principle of the supporting base 30 is as follows: when the height direction of the supporting foot 320 (i.e. the extending direction of the screw 310) needs to be adjusted, the adjusting knob 340 is rotated from the exposing hole 215 of the housing 21, the adjusting knob 340 drives the screw 310 to rotate, and during the rotation of the screw 310, the screw 310 moves in the height direction relative to the machine body 20, thereby achieving the height adjusting function of the supporting base 30. In this process, because the supporting foot 320 and the screw 310 can rotate relatively, the supporting foot 320 does not rotate, and the whole body 20 does not need to be lifted for adjustment, and the whole adjusting process does not shake the body 20, thereby preventing the parts in the body 20 from being damaged.

Second embodiment

The present embodiment provides another adjustable base apparatus 10, which is different from the first embodiment only in the structure of the supporting feet 320, and the same parts or details thereof can be referred to the related contents of the first embodiment, and are not described herein again.
