Description

Technical Field

[0001] The utility model relates to the field of bases, in particular to a bidirectional synchronous folding base. Background Art

[0002] A rotating and folding base is a base designed to support and stabilize various devices or objects. It can be rotated and folded to provide more flexibility and convenience. This base is usually composed of multiple foldable brackets or support arms, so that it can be expanded or folded as needed. The bottom of the base is usually designed as a stable support structure to ensure that the device or object has sufficient stability and safety when placed on it.

[0003] When the existing rotating and folding base is prepared and produced, its rotating connection usually adopts an extrusion or clamping braking method to ensure the stability of its working state. The extrusion braking method is to squeeze and brake the rotating part by rotating the threaded fastener, while the clamping braking method usually uses a clamping part that can slide but not rotate to brake the connection. Both of these braking methods require unlocking the braking part when adjusting it so that it can be folded and stored, which is not convenient for directly rotating it for folding and storage.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides Figure 1-5 A bidirectional synchronous folding base shown in the figure includes a base plate 1, the top of the base plate 1 is rotatably connected to a supporting shell 2, the top of the supporting shell 2 is provided with a connecting shell 3, the end of the connecting shell 3 is provided with a fixed shell 4, and a connecting assembly 5 is provided between the connecting shell 3 and the fixed shell 4 and the supporting shell 2. The connecting assembly 5 includes a connecting member 51, a mounting plate 52 and a limiting assembly 53. The connecting member 51 is installed inside the fixed shell 4, the mounting plate 52 is installed inside the connecting shell 3, and the limiting assembly 53 is arranged at the end of the mounting plate 52. Both ends of the mounting plate 52 have two protruding discs, so that the connecting member 51 can be rotatably connected relative to the mounting plate 52 through the limiting assembly 53, and braked. When a rotational torque force is applied between the mounting plate 52 and the connecting member 51, the fixed shell 4 and the supporting shell 2 can be rotated relative to the connecting shell 3, so that they are in an expanded use state or a folded storage state. The limiting assembly 53 is used to connect and brake the connecting member 51.

[0029] In particular, the limiting assembly 53 includes a bolt rod 531, a locking nut 532 and a limiting torsion spring 533. The outer wall of the bolt rod 531 is rotatably interlaced with the mounting plate 52 and the connecting member 51, and the top and bottom of the bolt rod 531 are provided with smooth surfaces, so that the cross-section of the bolt rod 531 is parallel to the top and the bottom, and the two sides are in a circular arc shape. The locking nut 532 is threadedly sleeved on one end of the outer wall of the bolt rod 531, and the limiting torsion spring 533 is slidably sleeved on the outer wall of the bolt rod 531. The limiting torsion spring 533 is located between the connecting member 51 and the locking nut 532, and under the action of the locking nut 532, the limiting torsion spring 533 is in compression, so that the limiting torsion spring 533 gives the bolt rod 531 an elastic extrusion force, so that the bolt rod 531 is squeezed and locked with the protrusion of the disc at the end of the mounting plate 52.

[0030] Furthermore, the outer wall of the bolt rod 531 is slidably clamped with a positioning disc 534, and the outer wall of the positioning disc 534 is provided with a ring-shaped array of grooves 535. One end of the limiting torsion spring 533 is slidably clamped in the interior of the groove 535. The hole on the positioning disc 534 corresponds to the bolt rod 531, so that the positioning disc 534 can only slide relative to the bolt rod 531 and cannot rotate relative to the bolt rod 531. The other end of the limiting torsion spring 533 is slidably clamped at the bottom of the connecting member 51, so that the limiting torsion spring 533 is clamped between the connecting member 51 and the positioning disc 534, so that the limiting torsion spring 533 can maintain a stable state. The outer wall of the bolt rod 531 is slidably clamped with a protective cover 5312 and a protective collar 5313, the protective cover 5312 and the protective ring 5313 are located between the locking nut 532 and the positioning disc 534, the holes on the protective cover 5312 and the protective ring 5313 correspond to the bolt rod 531, so that the protective cover 5312 and the protective ring 5313 can only slide relative to the bolt rod 531, and cannot rotate relative to the bolt rod 531, thereby ensuring the stability of the connection between the locking nut 532 and the bolt rod 531, the outer wall of the bolt rod 531 is slidably sleeved with a protective sleeve 536, the outer wall of the protective sleeve 536 is slidably sleeved with the limiting torsion spring 533, the outer wall of the bolt rod 531 is slidably sleeved with a snap ring 537, and the snap ring 537 is slidably snapped into the interior of the connecting member 51.

[0031] The outer wall of the bolt rod 531 is symmetrically slidably connected with a limiting ring 5310, and the limiting ring 5310 is slidably connected with the side of the mounting plate 52. The outer wall of the limiting ring 5310 is slidably connected with the inner wall of the limiting ring 5314, and the inner cavity of the positioning ring 538 corresponds to the bolt rod 531, so that the positioning ring 538 can only slide relative to the bolt rod 531 and cannot rotate relative to the bolt rod 531, and the slot 5314 has a certain width, so that when the inner wall of the slot 5314 on the connecting member 51 fits with the positioning projection 539, the connecting member 51 continues to rotate, so that the connecting member 51 can drive the bolt rod 531 to rotate through the positioning projection 539 and the positioning ring 538. The brake disc 5311 is connected to the mounting plate 52, and the brake disc 5311 is pressed and fitted with the limiting collar 5310 on one side of the mounting plate 52. The limiting collar 5310 can rotate relative to the bolt rod 531, but the brake disc 5311 can only slide relative to the bolt rod 531 and cannot rotate relative to the bolt rod 531. Therefore, under the action of the limiting torsion spring 533, the bolt rod 531 has an extrusion force that drives the brake disc 5311 toward the mounting plate 52, thereby causing the brake disc 5311 and the mounting plate 52 to be squeezed and braked. By adjusting the position of the locking nut 532 on the bolt rod 531, that is, changing the extrusion force of the limiting torsion spring 533, the extrusion braking force between the brake disc 5311 and the mounting plate 52 can be changed. In addition, a force of the connecting member 51 rotating relative to the mounting plate 52 can cause the connecting member 51 to drive the bolt rod 531 to rotate, so that the bolt rod 531 drives the brake disc 5311 to rotate relative to the mounting plate 52.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
