The specific structure of the portable stand according to the embodiment of the present invention will be described with reference to fig. 1 to 8.

As shown in fig. 1-2, the utility model discloses portable support includes telescopic link 1, connector 2, locking piece 3 and supporting component 4, and telescopic link 1 includes a plurality of members 11, and a plurality of members 11 cup joint the setting in proper order. As shown in fig. 4-5, the outer peripheral surface of each rod 11 includes a plurality of first planes S1 and a plurality of first convex surfaces S2, the plurality of first planes S1 and the plurality of first convex surfaces S2 are alternately distributed, the plurality of connectors 2 are connected to the sockets of two adjacent rods 11, the connectors 2 are connected to the rods 11 located on the outer side and sleeved on the rods 11 located on the inner side, the inner peripheral surface of the connectors 2 includes a plurality of second planes N1 and a plurality of second convex surfaces N2, the plurality of first planes S1 and the plurality of first convex surfaces S2 are alternately distributed, the plurality of locking members 3 are provided in one-to-one correspondence with the plurality of connectors 2, the locking members 3 are sleeved on the locking members 3 and the locking members 3 can drive the connectors 2 to rotate, the plurality of support members 4 are provided, the plurality of support members 4 are circumferentially spaced apart along the telescopic rod 1, and each support member 4 is foldably provided below the telescopic rod 1. As shown in fig. 4-5, the connecting head 2 has a locking position in which the first convex surface S2 of the inner lever 11 abuts against the second plane N1 and the inner lever 11 is locked to the outer lever 11; in the unlocking position, the first convex surface S2 of the inner lever 11 abuts against the second convex surface N2, the first plane S1 of the inner lever 11 abuts against the second plane N1, and the inner lever 11 can slide relative to the outer lever 11.

It can be understood that when the first plane S1 of the inner lever 11 abuts against the second plane N1 and the first convex surface S2 of the inner lever 11 abuts against the second plane N1, the inner lever 11 can slide relative to the outer lever 11. That is, the user can adjust the length of the telescopic rod 1, and when one of the two rods 11 rotates to make the first convex surface S2 of the rod 11 located at the inner side stop against the second plane N1, the connection and the locking piece 3 are in interference fit to lock the rod 11 located at the inner side on the rod 11 located at the outer side, that is, the length of the telescopic rod 1 is fixed and not adjustable. The rod 11 is provided with a plurality of first planes S1 and first convex surfaces S2 which are distributed at intervals, and the connecting head 2 is provided with a plurality of second planes N1 and second convex surfaces N2 which are distributed at intervals. Consequently, there are a plurality of closure positions and unblock position at closure 3 drive connector 2 in-process of rotating a week, like this when the user needs the length of adjustment telescopic link 1 or when locking telescopic link 1, only need with closure 3 rotate certain angle can, compare prior art and rotate the many rings of adjustment modes of knob, the utility model discloses an unblock or the closure operation of portable support are very simple. In addition, because the first plane S1 and the second convex surface N2 are multiple, when the connector 2 is located at the locking position, the acting forces applied to the connector 2 and the rod 11 located at the inner side are uniform, the abrasion probability of the connector 2 and the rod 11 is reduced, and the service lives of the telescopic rod 1 and the connector 2 are prolonged.

The utility model discloses a portable support, because be equipped with the first plane S1 and the first convex surface S2 of a plurality of alternate distributions on the member 11, be equipped with the second plane N1 and the second convex surface N2 of a plurality of alternate distributions on the connector 2, it drives the in-process that connector 2 rotated a week at closure 3, connector 2 has a plurality of unblock positions and locking position, consequently, only need when user needs closure or unblock member 11 with the closure 3 rotate certain angle can, not only convenient user operation, can also make the comparatively even distribution of effort between connector 2 and the member 11 between the two, the wearing and tearing that are connected with member 11 have been reduced, the reliability of use of portable support has been promoted, the life of portable support has been prolonged.

It should be added and described here that, in the portable stand of the present invention, since the locking member 3 is sleeved on the connector 2, the whole portable stand has no asymmetric abrupt structure in appearance, and the aesthetic degree of the portable stand is improved. In addition, in the process that the locking piece 3 drives the connecting head 2 to rotate for one circle, the connecting head 2 has a plurality of unlocking positions and locking positions, so that the locking piece 3 does not have the limitation of the unlocking direction and the locking direction. That is, in the actual operation, the locking member 3 can be rotated in the clockwise direction to unlock or lock the lever 11, and can be rotated in the counterclockwise direction to unlock or lock the lever 11.

In some preferred embodiments, as shown in fig. 4-5, the cross-sectional shape of the outer periphery of the locking element 3 is an equilateral triangle, which not only improves the aesthetic appearance of the portable stand, but also facilitates the holding and rotation of the portable stand by the user. Of course, in other embodiments of the present invention, the cross-sectional shape of the outer periphery of the locking element 3 may be other shapes such as a quadrangle and a circle, and is not limited to the equilateral triangle in this embodiment.

In some preferred embodiments, as shown in fig. 4-5, the first plane S1, the first convex surface S2, the second plane N1, and the second convex surface N2 are all five. It can be understood that the number of the planes is large, so that the number of the unlocking positions and the locking positions of the connector 2 is too large, the central angle occupied by each of the unlocking positions and the locking positions is small, the operation is inconvenient for a user, and the connector 2 can be easily moved from the locking position to the unlocking position by touching the locking part 3 by mistake of the user, so that the reliability of the portable support is reduced. However, the number of the above-mentioned planes is small, and the locking member 3 needs to be rotated by a large angle to move from the locking position to the unlocking position, so that it is inconvenient for the user to operate. Therefore, when the first plane S1, the first convex surface S2, the second plane N1 and the second convex surface N2 are all five, the operation of the user can be facilitated, and the reliability of the portable stand can be ensured.
