Referring to fig. 1 to 48, and particularly to fig. 5, 7, 12, 37, 40, 46, etc., an embodiment of the present utility model proposes a telescopic leg 1a, wherein the telescopic leg 1a is one of the legs 1 of the multi-leg stand, the telescopic leg 1a comprises a first support member 100 and a second support member 200, the first support member 100 is provided with at least one first sliding groove 101 and at least one first mounting opening 102, the at least one first mounting opening 102 corresponds to the at least one first sliding groove 101 respectively, the first mounting opening 102 communicates with the corresponding first sliding groove 101, the second support member 200 comprises at least one strut 210 corresponding to the at least one first sliding groove 101 respectively, a first end of the strut 210 is insertable into the corresponding first sliding groove 101 through the corresponding first mounting opening 102 such that the strut 210 is slidably mounted to the first sliding groove 101, the strut 210 is slidably mounted to the corresponding first sliding groove 101 to change the length of the telescopic leg 1a, and the first end of the strut 210 gradually moves away from the first support member 100 during extension of the telescopic leg 1 a; the strut 210 is configured to be positionable in the first support 100 when the telescoping leg 1a is in a supported state.
When the telescopic support 1a of the embodiment of the present utility model is not used, the support rod 210 is slidable relative to the first sliding groove 101 so that the length of the telescopic support 1a is shortened, and thus the occupied volume of the telescopic support 1a is reduced, and thus the occupied volume of the telescopic support is reduced. And the telescopic leg 1a is provided with a first mounting opening 102 to facilitate the mounting of the strut 210 to the first support 100.
It will be appreciated that when the telescoping leg 1a is extended to its longest state, the first end of the strut 210 protrudes from the first sliding channel 101.
It is understood that the number of the first mounting openings 102 is the same as the first sliding grooves 101, and the number of the struts 210 is the same as the first sliding grooves 101.
Illustratively, the multi-foot stand may be a tripod stand, a tetrapod stand, a pentapod stand, a hexapod stand, i.e., the number of feet 1 of the multi-foot stand may be 3, 4, 5, 6, etc.
Illustratively, referring to fig. 38, the multi-foot stand is used to support the power consumption main body 2, and the power consumption main body 2 may be a fan, a lamp, a mobile phone, a tablet, a camera, or the like. For example, when the power consumption body 2 is a lamp, the multi-foot stand may be a light supplementing stand, and when the power consumption body 2 is a photographing terminal 2 such as a mobile phone, a tablet, a camera, or the like, the multi-foot stand may be a photographing stand.
Illustratively, referring to fig. 37, the first mounting opening 102 communicates with an end of the first sliding groove 101, or the first mounting opening 102 communicates with a side of the first sliding groove 101, or the first mounting opening 102 communicates with both an end and a side of the first sliding groove 101. The provision of the first mounting opening 102 has the advantage of facilitating the insertion of the strut 210 into the first sliding channel 101. It will be appreciated that the first mounting opening 102 may be any opening that facilitates insertion of the strut 210 into the first slide channel 101.
Illustratively, the struts 210 may be positioned at any location on the first support 100, or the struts 210 may be positioned at a particular location on the first support 100.
Illustratively, the strut 210 is in damping contact with the first sliding channel 101 to enable positioning at the first support 100 when the telescoping leg 1a is in a supported state, e.g. the strut 210 is interference fit with the first sliding channel 101 or the strut 210 is provided with damping shims with the inner wall of the first sliding channel 101.
Illustratively, a locking member is disposed between the strut 210 and the first support 100; a locking member, which may be mounted to the first support 100, locks the strut 210 to the first support 100 when the telescoping leg 1a is in the support state, and which may be adjusted to lock or unlock the strut 210 relative to the first support frame. For example, the locking member may be a threaded member threadedly mounted to the first support member 100, rotating the threaded member may cause it to abut or release the strut 210, the locking member may be a cam locking member rotatably mounted to the first support member 100, and rotating the boss locking member may cause it to abut or release the strut 210.
For example, referring to fig. 6, 46, etc., the first support 100 has a first positioning protrusion 110, the strut 210 has a second positioning protrusion 211a, the second positioning protrusion 211a abuts against or slides over the first positioning protrusion 110 when the strut 210 slides with respect to the first sliding groove 101, and the second positioning protrusion 211a abuts against the first positioning protrusion 110 to position the strut 210 to the first support 100 when the telescopic leg 1a is in a supported state. For example, the boss 211 or a portion of the boss 211 may be the second positioning boss 211a.
For example, referring to fig. 32 or 65, in the telescopic leg 1a, when the strut 210 is only subjected to a tensile force or a compressive force in the sliding direction thereof, the strut 210 is in a loose fit or a tight fit with the first support 100, for example, the strut 210 is in a clearance fit with the first sliding groove 101. When the telescopic foot 1a is in a supported state, (for example only, the telescopic foot 1a may have an angle of 45 ° -89.9 °, such as 45 °, 60 °, 67 °, 75 °, etc.) with the plumb line, the pressure F of the first support 100 against the strut 210 may be decomposed into a component F1 perpendicular to its sliding direction and a component F2 along its sliding direction, the component F1 providing a friction force (tangential constraint force) F between the first support 100 and the first support 100, when f=f2, the strut 210 is positioned to the first support 100. The first support 100 has a first contact surface 103 in contact with the strut 210, the strut 210 is in frictional contact with the first contact surface 103 when the telescopic leg 1a is in the supporting state, F1 is parallel to the first contact surface 103, F2 is perpendicular to the first contact surface 103, F is parallel to the first contact surface 103, and when f=f2, the strut 210 is positioned at the first support 100. The first contact surface 103 may be two opposite sides of the first sliding groove 101.

Illustratively, the first sliding groove 101 is a cylindrical groove (may be a single cylindrical groove, a stepped cylindrical groove, etc.), such as a cylindrical groove, fang Zhucao, a polygonal cylindrical shape, etc. It will be appreciated that when the first support 100 is an injection molded part, the first sliding channel 101 is allowed to have a draft angle, in which case the first sliding channel 101 is an approximately cylindrical channel.
Illustratively, the first sliding channel 101 may be any shaped channel that accommodates sliding movement of the strut 210.
Illustratively, the struts 210 may be columnar (may be single columnar, stepped columnar, etc.), such as cylindrical rods, square columnar rods, polygonal columnar rods, etc.
In some implementations of embodiments of the present utility model, referring to fig. 1-48, and in particular to fig. 10 and 38, the first support 100 is configured to be supported on a support surface 1001 when the telescoping leg 1a is in a supported state, the second support 200 further comprises a foot pad 220, and the foot pad 220 is configured to be supported on the support surface 1001 when the telescoping leg 1a is in a supported state; after the strut 210 is inserted into the first sliding groove 101 through the first mounting opening 102, a first end of the strut 210 may protrude from the first sliding groove 101 such that the strut 210 is detachably connected with the footer 220.
The advantage of removably mounting the foot pad 220 with the post 210 is that the post 210 is conveniently inserted into the first slide through the first mounting opening 102.
Illustratively, a first end of strut 210 is detachably connected to foot pad 220.
Other examples are where the other portion of the strut 210 protruding from the first sliding groove 101 is detachably connected at the foot pad 220.
