Furthermore, the terms "horizontal", "vertical" and the like do not imply that the components are required to be absolutely horizontal or pendant, but rather may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present application, it is further noted that, unless expressly stated or limited otherwise, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

In one aspect of the embodiments of the present application, as shown in fig. 1 and 2, a support adjustment mechanism is provided, which includes an elastic member 500, a supporting leg 100, a matching component 300, and a support base 200 having a sliding slot 210, wherein the matching component 300 is slidably disposed in the sliding slot 210, the supporting leg 100 penetrates through the support base 200, and a penetrating direction of the supporting leg 100 penetrating through the support base 200 intersects with a sliding direction of the matching component 300 in the sliding slot 210, and in some embodiments, as shown in fig. 1 and 2, the penetrating direction may be perpendicular to the sliding direction. In this way, the threads provided on the mating assembly 300 can be made to approach or depart from the threads provided on the leg 100 under different forces, enabling engagement and disengagement of the threads.

As shown in fig. 1 and 2, the support leg 100 and the mating component 300 are respectively provided with threads, for the sake of distinction, a first thread is provided on the support leg 100, and a second thread 311 is provided on the mating component 300, and the first thread and the second thread 311 can be engaged with each other to realize a threaded connection. The elastic member 500 is connected to the mating component 300, so that the elastic member 500 can apply an acting force to the mating component 300 when deformed, the acting force can make the mating component 300 have a tendency to slide in the sliding groove 210, so that the second thread 311 has a tendency to be engaged close to the first thread, and after the first thread and the second thread 311 are engaged under the action of the elastic member 500, a limit along the gravity direction is formed on the supporting leg 100 for the mating component 300. When an external force is applied to the leg 100, the leg 100 moves in the penetrating direction and applies a component force to the fitting assembly 300 in the sliding direction of the fitting assembly 300, so that the fitting assembly 300 can slide relative to the support base 200 against the force of the elastic member 500, and the first and second threads 311 are disengaged.

In actual use, providing one or more support adjustment mechanisms on the device may be accomplished by attaching the support base 200 to the device. When the support base 200 is placed, one end of the support leg 100 can be supported on the placement ground of the equipment, and the height of the position of each support adjusting mechanism of the equipment is adjusted by adjusting the axial position of the support base 200 on the support leg 100.

As shown in fig. 12 and 13, after the first and second threads 311 are closed and engaged by the elastic member 500, the foot 100 is threadedly connected with the whole body formed by the support base 200, the elastic member 500 and the mating component 300, and the whole body formed by the support base 200, the elastic member 500 and the mating component 300 is limited to the foot 100 in the gravity direction, i.e. the whole body does not move axially relative to the foot 100 when the operator does not adjust the operation.

When fine adjustment is required, as shown in fig. 12, the foot 100 can be rotated clockwise or counterclockwise (both in the horizontal plane in fig. 12) to achieve fine adjustment of the position of the support base 200 on the foot 100, which fine adjustment helps the device achieve more accurate leveling.

When a quick adjustment is required, as shown in fig. 14 and 15, a force F1 in the direction of gravity may be applied to the leg 100, and at this time, the leg 100 will transmit a force to the mating assembly 300 through the screw engagement, so that the mating assembly 300 generates a component force sliding along the sliding slot 210, which overcomes the elastic force of the elastic member 500 to the mating assembly 300, so that the second screw 311 on the mating assembly 300 is far away from the first screw on the leg 100, thereby releasing the screw engagement, and after the screw engagement is released, the leg 100 can move relative to the support base 200 in the direction of gravity, thereby changing the height of the support base 200 on the leg 100, and achieving the quick adjustment. After the leg 100 presses the second thread 311 of the mating assembly 300 to move away from the first thread of the leg 100 for disengagement, the second thread 311 of the mating assembly 300 tends to move closer to the first thread for engagement under the elastic force of the elastic member 500, so that when the force F1 is not removed, the second thread 311 moves away from and moves closer to the first thread for disengagement and engagement repeatedly during the quick adjustment. After the force F1 is removed, the acting force of the supporting leg 100 on the mating component 300 disappears, the second thread 311 of the mating component 300 is close to the first thread under the action of the elastic member 500, and the two threads are engaged with each other, so that the supporting base 200 and the mating component 300 form a limit position relative to the supporting leg 100 along the gravity direction, that is, the supporting adjustment mechanism has the characteristic of self-locking at any time during quick adjustment, thereby avoiding the need of additional self-locking operation during adjustment, and effectively simplifying the operation steps during quick adjustment.

Because the quick adjustment can be adjusted by a wide margin, the fine setting can be finely adjusted, consequently, when using quick adjustment and fine setting together, can will support the equipment that guiding mechanism connects and adjust to the target height fast and accurately in the short time, improve user's use and experience.

In some embodiments, as shown in fig. 3, 4 and 5, a connection portion 400 is disposed on one side of the support base 200, the connection portion 400 includes a positioning member, a mounting groove 420 and a positioning hole 410, the mounting groove 420 is communicated with the positioning hole 410, the leg portion of the device is inserted into the mounting groove 420, and then the positioning member is inserted into the positioning hole 410 and is clamped and limited with the leg portion of the device, so that the support adjustment mechanism and the device are fixedly connected. In some embodiments, the positioning element may be in threaded connection with the positioning hole 410, and may also be in connection with a leg-portion distribution shaft of the device through the positioning hole 410, and the positioning hole 410 may be a counter bore. In some embodiments, as shown in FIG. 3, the leg portion of the device may be a cylinder and the mounting slot 420 may be an annular slot, which are matingly connected.

Alternatively, as shown in fig. 2, the fitting assembly 300 includes a locking member 310 and an unlocking member 320, and as shown in fig. 8, an abutting portion 325 and a driving portion 324 are provided on the unlocking member 320. As shown in fig. 9, a second screw 311 engaged with the leg 100 is provided on the locking member 310. In some embodiments, as shown in fig. 2 and 7, the elastic member 500 is a spring, one end of which is connected to the groove wall of the sliding groove 210, and the other end of which extends into the blind hole 323 of the unlocking member 320 and is connected to the unlocking member 320. In some embodiments, as shown in fig. 3 to 6, a sliding slot 210 is formed on the support base 200, through holes 230 communicating with the sliding slot 210 are respectively formed on two opposite sidewalls of the sliding slot 210, and one end of the supporting leg 100 passes through the two through holes 230 and the sliding slot 210 to be connected with the support base 200. In some embodiments, the unlocking member 320 may be a sliding block, and the sliding block may be disposed on the outer periphery of the supporting leg 100 in a semi-ring form after being located in the sliding groove 210, or, as shown in fig. 7 and 8, a groove 321 is formed in the sliding block, and the groove 321 may be used for accommodating the locking member 310, so that the locking member 310 has better stability in the movement process, a waist-shaped hole 3211 is formed at the bottom of the groove 321, and the supporting leg 100 passes through the waist-shaped hole 3211 of the sliding block when passing through the sliding groove 210, that is, the sliding block is disposed on the outer periphery of the supporting leg 100 in a ring form, so that the sliding stability of the sliding block can be improved. It should be noted that the length of the inner diameter of the waist-shaped hole 3211 along the sliding direction of the unlocking piece 320 should satisfy the length of the movement stroke required by the unlocking piece 320 to unlock.

As shown in fig. 13, after the components are assembled in the above manner, since the elastic member 500 is connected to the unlocking member 320, when no external force is applied, the elastic member 500 applies an elastic force to the unlocking member 320, so that the abutting portion 325 of the unlocking member 320 drives the locking member 310 to move, so that the locking member is engaged with the leg screw 630, and the support base 200 has a state of being engaged with and limited by the leg 100 in the gravity direction by the functional relationship between the locking member 310 and the support base 200, the unlocking member 320 and the leg 100, respectively. As shown in fig. 14 and 15, when a fast adjustment is required, a force F1 in the direction of gravity is applied to the leg 100, the force F1 transmits a force to the locking member 310 through the leg 100, so that the locking member 310 moves to the driving portion 324, the driving portion 324 drives the unlocking member 320 to slide in the sliding slot 210, so that the second thread 311 is away from the first thread, and the unlocking of the locking member 310 and the leg 100 is realized, and similarly, under the combined action of the force F1 and the elastic force, the second thread 311 repeatedly unlocks and engages with the first thread, and in this process, the support base 200 fast adjusts the height relative to the leg 100. When the force F1 is removed, the support adjustment mechanism enters a self-locking stage, and the unlocking member 320 pushes the locking member 310 out of the driving portion 324 through the abutting portion 325 under the action of the elastic force, and the second thread 311 on the locking member 310 is close to the leg 100 to complete the thread engagement with the leg 100.

In some embodiments, as shown in fig. 8 and 13, the driving portion 324 includes an inclined surface, and the inclined surface is configured to allow the locking member 310 to have a certain space therebetween when the locking member 310 is engaged with the inclined surface, so that, during rapid adjustment, the leg 100 can drive the locking member 310 to move in the space to switch the locking member 310 from the abutting portion 325 to the inclined surface of the driving portion 324, so that the locking member is pressed against the inclined surface 640, and a component force is generated in a sliding direction of the unlocking member 320 relative to the sliding groove 210 due to the inclined surface, and the component force causes the unlocking member 320 to slide relative to the support base 200, so that the second thread 311 on the locking member 310 can be away from the first thread to achieve disengagement.

In some embodiments, the movement of the locking member 310 from the abutment 325 to the driving portion 324 can be a rotation, i.e., as shown in fig. 13, the unlocking member 320 pushes the locking member into threaded engagement 630 with the leg through the abutment 325 under the action of the elastic member 500, as shown in fig. 14, after the force F1 is applied to the leg 100, the leg 100 drives the locking member 310 to rotate, so that the locking member 310 rotates to press against the inclined surface. In order to improve the stability of the crimping, as shown in fig. 11, the locking member 310 may be further provided with a crimping surface 315 engaged with the inclined surface. In some embodiments, the driving portion 324 may also be a stepped structure, and similarly, the locking member 310 may move and be pressed against the stepped structure, so that the unlocking member 320 slides.

In some embodiments, as shown in fig. 8, the abutment 325 comprises a first vertical surface, as shown in fig. 10, and the lock 310 comprises a second vertical surface 314, and when mated, as shown in fig. 13, when the lock 310 is engaged with the foot 100, the abutment position 610 of the abutment and the lock is in contact through the first vertical surface and the second vertical surface 314 only under the force of the spring 500. The form of the surface contact may be such that the locking member 310 may be able to rotate out of the way of the ramp when engaged with the foot 100.

Alternatively, as shown in fig. 3, 5 and 6, a second step 220 is provided on one side wall of the slide groove 210, and as shown in fig. 10, a first step 313 is provided on a side wall of the locking member 310, which faces the slide groove 210, on which the second step 220 is provided, and the first step 313 and the second step 220 are engaged with each other. As shown in fig. 13, in the state that the locking member 310 is engaged with the leg 100, the first step abuts against the second step 620, so that the stability of the support base 200 relative to the leg 100 in the engaged state can be further improved, and the support base 200 is prevented from sliding relative to the leg 100 accidentally. In this embodiment, during the rapid adjustment, as shown in fig. 13, during the movement of the locking member 310 driven by the supporting leg 100, the first step 313 and the second step 220 are released from the abutment, and then pressed against the driving portion 324, so as to drive the unlocking member 320 to slide relative to the supporting base 200, so that the locking member 310 is disengaged from the supporting leg 100.

In some embodiments, as shown in fig. 10, first step 313 includes a blocking wall 3131 and a transition wall 3132, and first step 313 abuts second step 220 through blocking wall 3131. In the case of quick adjustment, as shown in fig. 13, during the movement of the locking member 310 driven by the leg 100, the blocking wall 3131 of the first step 313 slides away from the second step 220 and then is abducted by the transition wall 3132, so that the entire first step 313 is separated from the second step 220 to release the abutment, and after the abutment is released, the locking member 310 can slide along the sliding groove 210 together with the unlocking member 320 to release the threaded engagement between the locking member 310 and the leg 100. As shown in fig. 10, the blocking wall 3131 may be a vertical wall, and the transition wall 3132 may be an inclined surface or a rounded surface, etc., adjacent to the vertical wall.

Alternatively, the quick adjustment may be performed in another manner, as shown in fig. 7, in which an unlocking portion 322 is provided on the unlocking member 320, and as shown in fig. 9, in which an acting portion 312 engaged with the unlocking portion 322 is provided on the locking member 310. As shown in fig. 16, when a quick adjustment is required, a force F2 can be applied to the unlocking member 320 at the opening position of the sliding slot 210, the force F2 will drive the unlocking member 320 to slide relative to the sliding slot 210, and during the sliding of the unlocking member 320, the driving part 312 will be guided by the unlocking part 322 to move, i.e. the locking member 310 is moved, so that the locking member 310 is disengaged from the leg 100, and at this time, the leg 100 can be moved quickly relative to the support base 200 by applying a force F3 to the leg 100, so as to achieve the quick adjustment. When the forces F3 and F1 are opposite in direction as shown in FIGS. 14 and 16, the height adjustment of the support base 200 along the leg 100 can be accomplished in the manner previously described. Of course, when the force F2 is applied to drive the unlocking member 320 to move to unlock the screw engagement, the leg 100 may be applied with the force F3 or the force F1 according to different adjustment requirements, and at this time, the height adjustment of the supporting base 200 can be realized.

Alternatively, as described above, the locking member 310 and the slide groove 210 are provided at opposite sides thereof with the first step 313 and the second step 220, respectively, which are engaged with each other, and the first step and the second step abut 620 in the state where the locking member 310 is engaged with the leg 100. In this embodiment, the unlocking part 322 includes a guide wall and a driving wall, as shown in fig. 16, when the locking member 310 engages with the leg 100, the acting part corresponds to the guide wall position 650, as shown in fig. 17 and 18, when a force F2 is applied to the unlocking member 320, the unlocking part 322 follows the unlocking member 320, the acting part 312 of the locking member 310 moves, for example, rotates under the guide drive of the guide wall of the unlocking member 322, the locking member 310 follows the acting part 312, so that the first step 313 moves, when the acting part 312 moves to the driving wall, the first step 313 is disengaged from the second step 220, and as the unlocking member 320 continues to slide, the driving wall drives the acting part 312 to disengage the locking member 310 from the leg 100. In some embodiments, as shown in fig. 9, the action portion 312 may be a rounded step on the locking member 310, and the rounded corner may make the unlocking portion 322 smoother when acting on the action portion 312.

Optionally, as shown in fig. 2, the support leg 100 includes a screw 120, and a handle 110 and a disc 130 respectively disposed at two ends of the screw 120, and the disc 130 may increase a contact area between the support adjusting mechanism and the ground, so as to improve the stability of the support. The handle 110 may facilitate manipulation of the support adjustment mechanism for fine adjustment. During installation, the locking member 310 may be first placed in the groove 321 of the unlocking member 320, such that the pressing surface 315 of the locking member 310 corresponds to the inclined surface of the unlocking member 320, the elastic member 500 is loaded into the blind hole 323 of the unlocking member 320 to form the sub-module, and the sub-module is loaded into the support base 200 along the opening of the sliding groove 210. Then the disc 130 at one end of the support leg 100 is detached, one end of the support leg 100 penetrates out from the through hole 230 at one end of the support base 200, the sliding groove 210 in the support base 200, the groove 321 of the unlocking piece 320, the waist-shaped hole 3211 of the unlocking piece 320 to the through hole 230 at the other end of the support base 200, and then the disc 130 is installed to form a support adjusting mechanism, thereby realizing the above-mentioned various functions.
