DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of an adjustable multi-angle support arm structure provided by the utility model; Figure 2 for Figure 1 A front view of an adjustable multi-angle support arm structure is shown; Figure 3 for Figure 1 A front cross-sectional view of a flip column in an adjustable multi-angle support arm structure; Figure 4 for Figure 1 The front view of the base in an adjustable multi-angle support arm structure is shown. An adjustable multi-angle support arm structure comprises a base 1, a rotating column 2 is movably sleeved inside the base 1, a No. 1 gear 3 is fixedly sleeved outside the rotating column 2, a support column 4 is fixedly connected to the top of the rotating column 2, a sliding ball 5 is movably sleeved on the top of the base 1, a flip column 6 is movably sleeved on the top of the support column 4, a storage groove 7 is provided on the front of the flip column 6, an extension column 8 is movably sleeved inside the storage groove 7, a folding column 9 is movably sleeved on one end of the extension column 8, a support arm 10 is movably sleeved on one end of the flip column 6, a bolt 11 is sleeved on the internal thread of the support arm 10, a rotating shaft 12 is movably sleeved on one end of the support arm 10, a fixing clamp 13 is fixedly connected to one end of the rotating shaft 12, a non-slip plate 14 is fixedly sleeved on the inside of the fixing clamp 13, a positioning mechanism 15 is provided at one end of the support arm 10, and a rotating mechanism 16 is provided inside the base 1.

[0025] The extension column 8 and the flip column 6 are parallel to each other, and the extension column 8 is adapted to the storage slot 7; by setting the extension column 8, when the object is supported by the support arm, the extension column 8 is pulled to move the extension column 8 out from the storage slot 7. At this time, the two extension columns 8 can support other parts of the object through the folding column 9, thereby achieving the effect of supporting multiple parts of the object, thereby avoiding the problem of needing to use multiple support arms at the same time when supporting multiple parts of the object, thereby greatly improving the practicality of the support arm.

[0026] The bolt 11 is threadedly sleeved inside the flip column 6, and the bolt 11 and the support arm 10 are perpendicular to each other; by setting the bolt 11, when it is necessary to adjust the length of the support arm, the bolt 11 is rotated so that the bolt 11 can be moved out from the inside of the flip column 6. At this time, the support arm 10 can be flipped outside the flip column 6, thereby achieving the effect of adjusting the position of the fixing clamp 13, and then achieving the effect of adjusting the length of the support arm.

[0027] The fixing clip 13 and the support arm 10 are parallel to each other, and the material of the fixing clip 13 is stainless steel. By setting the fixing clip 13, when supporting an irregular object, the fixing clip 13 is squeezed so that the fixing clip 13 can be opened. At this time, the object is placed inside the fixing clip 13, so that the fixing clip 13 can clamp the object, thereby achieving the fixing effect of the object, thereby bringing convenience to the support and fixation of the object.

[0028] The anti-skid plate 14 is made of rubber material, and there are two anti-skid plates 14, which are parallel to each other. By setting the anti-skid plate 14, when clamping and fixing an object, the anti-skid plate 14 can greatly increase the friction between the object and the fixing clamp 13, thereby avoiding the problem of the object falling off from the inside of the fixing clamp 13 due to the smooth surface of the object, thereby improving the stability of the object after fixation.

[0029] The positioning mechanism 15 includes a positioning sleeve 151, which is fixedly connected to one end of the support arm 10, and the positioning sleeve 151 is movably sleeved on the outside of the rotating shaft 12. The internal thread of the positioning sleeve 151 is sleeved with a threaded column 152; by setting the positioning mechanism 15, when it is necessary to adjust the support angle of the support arm, the threaded column 152 is rotated so that the threaded column 152 can be moved out from the inside of the positioning sleeve 151. At this time, the rotating shaft 12 can drive the fixing clamp 13 to rotate, thereby achieving the convenience of adjusting the clamping angle of the fixing clamp 13, thereby facilitating the angle adjustment of the support arm.

[0030] The rotating mechanism 16 includes a rotating motor 161, which is fixedly installed inside the base 1. A second gear 162 is fixedly sleeved on the output shaft of the rotating motor 161, and the second gear 162 is meshed with the first gear 3. By setting the rotating mechanism 16, when it is necessary to adjust the supporting direction of the support arm, the rotating motor 161 is started, so that the rotating motor 161 can drive the first gear 3 to rotate through the second gear 162, that is, drive the support column 4 to rotate, and enable the fixing clamp 13 to rotate around the base 1, thereby achieving the effect of adjusting the supporting direction of the support arm, which brings convenience to the use of the support arm.

[0031] There are several sliding balls 5, which are evenly distributed on the top of the base 1. By setting the sliding balls 5, when the flip column 6 is adjusted in the reverse direction, the sliding balls 5 can limit the support column 4 in rotation, thereby avoiding the friction between the heavy arm and the top of the base 1 during rotation, causing the support column 4 to tilt when it is severely worn, thereby greatly improving the service life of the arm.

[0032] The working principle of the adjustable multi-angle support arm structure provided by the utility model is as follows:

[0033] Step 1: First, when the support arm is used to support an object, pull the extension column 8 so that the extension column 8 can be moved out from the storage slot 7. At this time, the two extension columns 8 can support other parts of the object through the folding column 9, thereby achieving the effect of supporting multiple parts of the object, thereby avoiding the problem of using multiple support arms at the same time when supporting multiple parts of the object, thereby greatly improving the practicality of the support arm. When the length of the support arm needs to be adjusted, rotate the bolt 11 so that the bolt 11 can be moved out from the inside of the flip column 6. At this time, the support arm 10 can be flipped outside the flip column 6, thereby achieving the fixing clamp 13. The adjustment effect of the position can achieve the adjustment effect of the arm length. When supporting an irregular object, the fixing clamp 13 is squeezed to open the fixing clamp 13. At this time, the object is placed inside the fixing clamp 13, so that the fixing clamp 13 can clamp and fix the object, thereby achieving the object fixing effect, which brings convenience to the support and fixation of the object. When clamping and fixing the object, the anti-slip plate 14 can greatly increase the friction between the object and the fixing clamp 13, so as to avoid the problem that the object falls off from the inside of the fixing clamp 13 due to the relatively smooth surface of the object, thereby improving the stability of the object after being fixed.

[0034] Step 2: When it is necessary to adjust the supporting angle of the support arm, rotate the threaded column 152 so that the threaded column 152 can be moved out of the positioning sleeve 151. At this time, the rotating shaft 12 can drive the fixing clamp 13 to rotate, thereby achieving the clamping angle adjustment of the fixing clamp 13, which brings convenience, thereby facilitating the angle adjustment of the support arm. When it is necessary to adjust the supporting direction of the support arm, start the rotating motor 161 so that the rotating motor 161 can drive the first gear 3 to rotate through the second gear 162, that is, drive the support column 4 to rotate, so that the fixing clamp 13 can rotate around the base 1, thereby achieving the supporting direction adjustment effect of the support arm, thereby facilitating the use of the support arm. When the flip column 6 is adjusted in the reverse direction, the sliding ball 5 can limit the support column 4 in rotation, thereby avoiding the friction between the heavy arm and the top of the base 1 during rotation, resulting in the problem of tilting of the support column 4 when it is severely worn, thereby greatly improving the service life of the support arm.

[0035] Compared with the related art, the adjustable multi-angle support arm structure provided by the utility model has the following beneficial effects:

[0036] By setting the extension column 8, when the support arm is used to support the object, the extension column 8 is pulled to move the extension column 8 out from the storage slot 7. At this time, the two extension columns 8 can support other parts of the object through the folding column 9, thereby achieving the effect of supporting multiple parts of the object, thereby avoiding the problem of needing to use multiple support arms at the same time when supporting multiple parts of the object, thereby greatly improving the practicality of the support arm.
