Furthermore, references herein to "an embodiment" mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present utility model. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

The embodiment of the utility model provides a support stand 100, as shown in fig. 1 and 2, the support stand 100 includes a main rod 10, a leg assembly 20 and a clamping structure 30. The leg assembly 20 includes a leg 21 and a connection rod 22, wherein the leg 21 can be folded on the main lever 10 or unfolded with respect to the main lever 10. In this embodiment, a support leg seat 23 is slidably sleeved on the outer peripheral wall of the main rod 10, and one end of the support leg 21 is pivotally connected to the support leg seat 23.

It will be appreciated that when the support stand 100 is in use, the leg rest 23 slides downwardly in the axial direction of the main rod 10, the leg rest 23 drives the legs 21 to slide downwardly, and each leg 21 expands away from the main rod 10 and abuts against a support platform (not shown) so that the support stand 100 can stably support an external device (not shown).

When the support stand 100 is not in use, the stand bar seats 23 slide upwards along the axial direction of the main rod 10, the stand bar seats 23 drive the stand bars 21 to slide upwards, and each stand bar 21 is folded towards the direction close to the main rod 10 to form a handle shape so as to reduce the occupied space of the support stand 100.

It should be noted that, the leg seat 23 only slides in a certain position of the main rod 10 and does not slide out of the main rod 10, and the leg 21 slides downward along the axial direction of the main rod 10 and exceeds the main rod 10 by means of the leg seat 23, which is equivalent to extending the height of the support stand 100 to increase the usable range of the support stand 100.

In addition, as shown in fig. 2, one end of the connection rod 22 is rotatably connected to the leg 21, and the other end is rotatably connected to the end of the main lever 10 so as to be openable and closable with respect to the main lever 10 together with the leg 21. As can be appreciated, when the leg 21 is unfolded relative to the main rod 10, the leg 21 can drive the connecting rod 22 to be unfolded, so as to enhance the stability of the support of the leg 21; when the support legs 21 are folded, the support legs 21 can drive the connecting rods 22 to fold, so that occupied space is reduced, and space utilization rate and portability are improved.

In addition, the engaging structure 30 is movably disposed at one end of the connecting rod 22 near the main rod 10. Wherein the engagement structure 30 can be extended from the end of the connection rod 22 to lock the leg 21 to the main rod 10 or retracted from the end of the connection rod 22 to unlock the leg 21.

As can be appreciated, when the leg 21 is folded on the main rod 10, the engaging structure 30 extends from the end of the connecting rod 22 to limit and lock the leg 21, thereby preventing the leg 21 from being unfolded; when the leg 21 needs to be unfolded, the engagement structure 30 is retracted from the end of the connection rod 22 to unlock the leg 21, so that the leg 21 can be unfolded smoothly.

It should be noted that, because the supporting foot rest 100 extends or retracts from the end of the connecting rod 22 through the engaging structure 30 to lock or unlock the supporting leg 21, compared with the manner of integrally forming the engaging protrusion and the end cover in the prior art, the area of the spacing fit between the engaging structure 30 and the supporting leg 21 can be increased, thereby improving the spacing locking effect on the supporting leg 21.

It should be further noted that, compared with the rigid clamping limit of the support leg 21 in the existing support leg 100, the clamping structure 30 in the support leg 100 is flexible and clamping limit, that is, the clamping structure 30 can extend out or retract from the end of the connecting rod 22, so that the problem that the clamping structure 30 is worn and disabled after long-time use can be avoided, and the durability of the support leg 100 is improved.

In order to better understand the solution of the present utility model by those skilled in the art, the following description will clearly and completely describe the solution of the embodiment of the present utility model with reference to fig. 1 to 8.

Further, as a specific implementation manner of some embodiments of the present utility model, as shown in fig. 2 to 5, the supporting leg 21 is convexly provided with a clamping protrusion 211 at a side facing the main rod 10, and the end of the connecting rod 22 near the main rod 10 is provided with a mounting groove 221. The locking structure 30 includes a locking block 31, and the locking block 31 is slidably mounted in the mounting groove 221, so that a portion of the locking block 31 can extend from an end of the connecting rod 22 and be in a limiting fit with the locking protrusion 211, or retract from an end of the connecting rod 22 to release the limiting fit with the locking protrusion 211.

As can be appreciated, when the support leg 21 is folded on the main rod 10, the buckling block 31 can move in a direction away from the connecting rod 22, so that a portion of the buckling block 31 extends out of the mounting groove 221 and is in limit fit with the clamping protrusion 211 on the support leg 21, thereby realizing a limit effect on the support leg 21.

Conversely, when the support leg 21 needs to be unfolded relative to the main lever 10, the latch block 31 can be moved in a direction approaching the connecting lever 22, so that a part of the latch block 31 is retracted into the mounting groove 221, and the limit engagement with the catching protrusion 211 on the support leg 21 is released, thereby allowing the support leg 21 to freely move.

It should be noted that, by adopting the locking block 31 capable of extending (or retracting) to perform a limit fit with the locking protrusion 211 of the stand bar 21, the problem of mutual abrasion failure between the locking protrusion 211 and the locking block 31 after long-term use can be avoided, thereby improving the durability of the support stand 100 and prolonging the service life thereof.

It should be further noted that, by movably mounting the buckling block 31 at the end of the connecting rod 22, a technician can increase the contact area (i.e., the limiting area) between the clamping protrusion 211 and the buckling block 31 by increasing the volume of the buckling block 31 extending out of the end of the connecting rod 22, thereby improving the limiting effect on the supporting leg 21.

In this embodiment, as shown in fig. 6 to 8, the locking block 31 is concavely provided with a clamping groove 311 adapted to the clamping protrusion 211, when the support leg 21 is folded on the main rod 10, the clamping protrusion 211 can extend into the clamping groove 311 to limit the support leg 21, or when the support leg 21 is unfolded relative to the main rod 10, the clamping protrusion 211 can be moved out of the clamping groove 311 to release the limit of the support leg 21.

It will be appreciated that when the leg 21 is folded over the main rod 10, a portion of the latch block 31 can extend from the end of the connecting rod 22, and at this time, the latch 211 on the leg 21 can extend into the latch slot 311 and abut against the slot wall of the latch slot 311, thereby limiting the leg 21 to a desired position. This ensures that the leg 21 does not move or deform accidentally, and is more stable and reliable when working.

When the support leg 21 needs to be unfolded, only the part of the buckling block 31 needs to be retracted from the end part of the connecting rod 22, and at this time, the clamping protrusion 211 on the support leg 21 moves out of the clamping groove 311, so that the limit on the support leg 21 is released, and the support leg 21 is unfolded freely.

Further, as a specific embodiment of the supporting stand 100 provided by the present utility model, the engaging structure 30 further includes a limiting component 32, where a part of the limiting component 32 is disposed on the buckling block 31, and another part of the limiting component is disposed on the connecting rod 22, so as to limit the sliding of the buckling block 31 when the buckling block 31 extends from or retracts from the end of the connecting rod 22. Therefore, in the use process of the clamping structure 30, the movement range of the buckling block 31 can be effectively controlled, interference of the buckling block 31 with other components is avoided, and therefore the stability and the safety of the structure are improved.

In this embodiment, as shown in fig. 7 and 8, the limiting assembly 32 includes a limiting rod 321, the buckling block 31 is provided with a limiting hole 312 along the sliding direction thereof, the limiting rod 321 extends into or passes through the limiting hole 312 in the mounting groove 221 and is fixedly mounted on the connecting rod 22 (i.e. one end of the limiting rod 321 is fixed on the connecting rod 22, and the other end of the limiting rod 321 extends into but does not pass through the limiting hole 312, or one end of the limiting rod 321 is fixed on the connecting rod 22, and the other end of the limiting rod 321 passes through the limiting hole 312 and is fixed on the other side of the connecting rod 22).

Wherein, when the button block 31 is extended or retracted from the end of the connecting rod 22, the limiting rod 321 can slide in the hole of the limiting hole 312 to limit the sliding of the button block 31. Through the cooperation of the limiting rod 321 and the limiting hole 312, the sliding of the buckling block 31 can be guided, so that the sliding of the buckling block 31 is smoother.

It should be noted that, by reasonably setting the length of the limiting hole 312, the length of the limiting hole 312 along the sliding direction of the latch block 31 is the range of the sliding travel of the latch block 31, which can be selected by those skilled in the art according to practical situations, and the present utility model is not limited thereto.

In another alternative embodiment, the limiting assembly 32 includes a limiting post (not shown) and a limiting groove (not shown) adapted to the limiting post, the limiting posts are disposed on the side wall of the buckling block 31, two limiting grooves are spaced apart from each other along the sliding direction of the buckling block 31, and when the buckling block 31 extends or retracts from the end of the connecting rod 22, the limiting posts can extend into the corresponding limiting holes 312 to limit the sliding of the buckling block 31. In this embodiment, the distance between the two limiting grooves is the range of the sliding travel of the latch block 31.
