Referring to fig. 1 to 3, for a support carrier 100 according to an embodiment of the present application, the support carrier 100 of the above-mentioned embodiment is applied to a use occasion for mounting and supporting a microphone or other electronic devices, and specifically, the microphone is assembled with a connecting bolt 21 of a connecting piece 20 to achieve the purpose of being mounted and fixed on a stand 10.

With continued reference to fig. 4, the support carrier 100 illustratively includes a bracket 10 and a connecting member 20, wherein a mounting hole 121 is formed at a top end of the bracket 10; the connecting piece 20 comprises a connecting bolt 21, a connecting seat 22 and an elastic piece 23, wherein the connecting bolt 21 is arranged on the connecting seat 22, the elastic piece 23 is arranged outside the connecting seat 22, and the connecting seat 22 is inserted into the mounting hole 121 so that the elastic piece 23 is elastically clamped and fixed with the hole wall of the mounting hole 121.

In this embodiment, the bracket 10 specifically includes a fixed tube 11, a movable tube 12, and a base 13, the movable tube 12 is installed in a lumen of the fixed tube 11, and the movable tube 12 can move telescopically with respect to the fixed tube 11. Preferably, the movable tube 12 and the fixed tube 11 are circular hollow tubes, and the outer tube diameter of the movable tube 12 is smaller than the inner tube diameter of the fixed tube 11, so that the movable tube 12 can be conveniently inserted into the tube cavity of the fixed tube 11 to complete installation, and the movable tube 12 can freely stretch and slide relative to the fixed tube 11.

Of course, the movable pipe 12 and the fixed pipe 11 may take the shape of square pipes or the like in other embodiments.

It will be appreciated that the mounting holes 121 are actually the top nozzles of the movable tube 12 itself, which may eliminate the need for separate hole site machining.

In practical use, the heights of different users are divided, and the microphone is close to the mouth of the user and can ensure a good use effect within a preset distance range, so that the support 10 is required to have the capability of height expansion and contraction. Therefore, when the movable tube 12 extends upward relative to the fixed tube 11, the overall length of the bracket 10 is increased, so that the microphone mounted on the top end of the fixed tube 11 can be lifted to a higher position, thereby meeting the requirements of users with higher heights. In contrast, when the movable tube 12 is manipulated to retract downward relative to the fixed tube 11, the overall length of the stand 10 becomes shorter, and the microphone is simultaneously lowered following the movable tube 12, thereby satisfying the need of a shorter user.

With continued reference to fig. 2, the base 13 is provided with a plugging hole 131, and the bottom end of the fixing tube 11 is inserted into the plugging hole 131 for fixing. The base 13 is placed on the ground and is used as a bearing substrate to support and fix the fixed pipe 11 and the movable pipe 12, namely, the stable and reliable installation and use of the support carrier 100 are ensured.

In summary, implementing the technical scheme of the embodiment has the following beneficial effects: when the support carrier 100 is assembled, the connecting piece 20 can be placed at the top end of the bracket 10, the connecting seat 22 is aligned with the mounting hole 121, and then the connecting seat 22 is pressed into the mounting hole 121 by force, so that the elastic piece 23 and the hole wall of the mounting hole 121 form elastic clamping connection, and the assembly and the fixation of the connecting piece 20 and the bracket 10 can be realized. Compared with the threaded connection structure in the prior art, the supporting carrier 100 can be assembled by pushing the connecting piece 20 into the mounting hole 121 of the bracket 10 and by means of elastic clamping of the elastic piece 23 and the hole wall of the mounting hole 121, so that the manufacturing difficulty and cost of the supporting carrier 100 are reduced without performing threaded machining, and meanwhile, the assembling mode and structure are simple and easy to implement.

Optionally, the connecting bolt 21, the connecting seat 22 and the elastic sheet 23 may be integrally formed or detachably assembled, and specifically, the connecting bolt, the connecting seat and the elastic sheet may be flexibly selected according to actual needs. Preferably, in this embodiment, the connecting bolt 21, the connecting seat 22 and the elastic piece 23 adopt an integral structure, so that the connecting piece 20 can obtain higher structural strength and better mechanical property, and the installation effect of the connecting piece 20 and the bracket 10 and the reliability of supporting the microphone are ensured.

The spring plate 23 may be made of a metal material having excellent elastic properties, such as copper, steel, etc. After the connecting piece 20 is inserted into the mounting hole 121, the connecting piece 20 and the movable tube 12 are coaxially arranged, and in order to ensure that the elastic piece 23 and the inner tube wall of the movable tube 12 form a reliable elastic clamping connection, the distance between the edge of the elastic piece 23 and the center of the connecting seat 22 should be slightly larger than the hole radius of the mounting hole 121.

With continued reference to fig. 4, preferably, the spring plate 23 includes a plurality of elastic arms 231 according to the above embodiment, the plurality of elastic arms 231 are sequentially arranged along the circumferential direction of the connecting seat 22, and a groove 232 is concavely formed between two adjacent elastic arms 231.

After the connecting seat 22 is pushed into the mounting hole 121, the plurality of elastic arms 231 are simultaneously elastically clamped with the wall of the mounting hole 121, so that the multi-point mounting and fixing structure is formed, the uniform stress of the connecting piece 20 is ensured, and the mounting is stable and reliable and is not easy to loose. The grooves 232 formed between two adjacent elastic arms 231 provide the degree of freedom required by deformation and bending of the elastic arms 231 due to the extrusion of the hole walls of the mounting holes 121, namely, ensure that the elastic arms 231 are easier to elastically deform and can be clamped with the hole walls of the mounting holes 121 more firmly.

Further, the connector 20 has a fitting direction F into which the mounting hole 121 is fitted. The inserting direction F can be specifically referred to fig. 2. All the elastic arms 231 are bent in an arc shape in a direction opposite to the inserting direction. Therefore, during the process of inserting the connecting seat 22 into the mounting hole 121, the elastic arm 231 bent in an arc shape with a certain angle can form an avoiding and guiding effect with the broken arm of the movable tube 12, so that the elastic arm 231 is easier to be clamped into the mounting hole 121.

Further, at least two spring plates 23 are provided on the basis of any of the above embodiments, and at least two spring plates 23 are disposed on the connecting base 22 at intervals along the inserting direction. After the arrangement, the elastic clamping connection between the connecting piece 20 and the movable pipe 12 is reinforced, the connecting strength is higher, and the influence on the supporting stability of the microphone caused by relative looseness of the connecting piece 20 on the movable pipe 12 is prevented.

With continued reference to fig. 2, in order to facilitate assembly and fixation of the fixing tube 11 and the base 13 and ensure sufficient connection strength, in some embodiments, a first external thread 111 is disposed on an outer wall of a bottom end of the fixing tube 11, and a first internal thread 131a is disposed on an inner wall of the plugging hole 131, where the first external thread 111 is screwed with the first internal thread 131 a.

Of course, in other embodiments, the screw connection structure of the first external thread 111 and the first internal thread 131a may be replaced by a fastening structure, a magnetic structure, an adhesive structure, or the like, which is specifically selected according to actual needs.

With continued reference to fig. 2 and 3, further, the bracket 10 further includes a blocking member 30, wherein the blocking member 30 is inserted into the lumen of the fixed tube 11 and disposed near the bottom end of the fixed tube 11, and the blocking member 30 is capable of being limited by abutting against the bottom end of the movable tube 12 in the retracted position. The blocking member 30 forms a barrier to the movable tube 12 before the fixed tube 11 is assembled with the base 13 or after the fixed tube 11 is disassembled from the base 13, thereby preventing the movable tube 12 from completely falling out of the fixed tube 11.

For example, the blocking member 30 is a silica gel block, and can be reliably fixed by directly clamping into the fixing tube 11 through friction force, so that the installation mode is simple and the use cost is low.

With continued reference to fig. 2 and 4, in addition, in some embodiments the bracket 10 further includes a friction ring 40, the friction ring 40 being disposed between the outer tube wall of the movable tube 12 and the inner tube wall of the fixed tube 11. Specifically, the friction ring 40 is fixedly installed on the fixed tube 11 and is in sliding contact with the movable tube 12, and the friction ring 40 applies a certain amount of friction resistance to the movable tube 12, thereby helping to control the speed of the movable rod when the movable tube 12 performs telescopic movement, so that the overall length (height) of the bracket 10 can be more accurately adjusted, and simultaneously, the operation feel of manually adjusting the movable tube 12 can be increased.

In order to enable the movable tube 12 to move telescopically relative to the fixed tube 11 when the length of the bracket 10 needs to be adjusted, the movable tube 12 and the fixed tube 11 can be kept fixed after the length of the bracket 10 is adjusted. In some embodiments, the bracket 10 further includes an adjustment fastener 50, the adjustment fastener 50 being movably sleeved outside the top end of the fixed tube 11, the adjustment fastener 50 having a first position and a second position, the adjustment fastener 50 being capable of driving the friction plate to pinch the movable tube 12 when the adjustment fastener 50 is in the first position so as to hold the movable tube 12 relatively fixed to the fixed tube 11, and the adjustment fastener 50 being capable of driving the friction plate to release the movable tube 12 when the adjustment fastener 50 is in the second position so as to allow the movable tube 12 to move relatively telescopically with respect to the fixed tube 11.

With continued reference to fig. 5, in particular, in the above embodiment, the side wall of the friction ring 40 is provided with expansion slits 41 extending in the axial direction and penetrating opposite ends, and the width of the expansion slits 41 provides the stroke required for expanding and deforming the friction ring 40.

The friction ring 40 comprises a mounting part 42 and a hooping part 43 which are coaxially connected, a clamping groove 421 extending in the circumferential direction is formed in the peripheral wall of the mounting part 42, and the clamping groove 421 is fixedly buckled with a clamping body preset at the top end of the fixed pipe 11, so that the friction ring 40 and the fixed pipe 11 can be assembled and fixed, the friction ring 40 is prevented from loosening when the movable pipe 12 is telescopically adjusted relative to the fixed pipe 11, and the limiting effect of the friction ring 40 on the movable pipe 12 is ensured. The hooping portion 43 protrudes to the top end of the fixed pipe 11 and hoops with the movable pipe 12 so as to form an effective contact with the friction ring 40, and the friction ring 40 is hooped or released against the hooping portion 43.

With continued reference to fig. 2 and 6, the outer wall of the top end of the fixing tube 11 is provided with a second external thread 112, the inside of the adjusting fastener 50 is provided with a second internal thread 51 and a raised ring 52 which are coaxially arranged, and the second external thread 112 is in threaded connection with the second internal thread 51; when the adjustment fastener 50 moves toward the base 13 and reaches the first position, the raised ring 52 is crimped to the outside of the hooping portion 43, and the hooping portion 43 contracts to tighten and fix the movable pipe 12; when the adjustment fastener 50 is moved in the direction of the connector 20 and reaches the second position, the raised ring 52 disengages from the contact collar 43, and the collar 43 expands to release the movable tube 12. According to the structural scheme, only the fastening piece 50 is required to be screwed in the clockwise direction, the fastening piece 50 is regulated to axially slide along the two directions of the movable tube 12, and the movable tube 12 can be rapidly and effectively flexibly switched between the fixed movable tube 12 and the released movable tube 12, so that the device is high in practicality, high in reliability and convenient and labor-saving to operate.
