Description

Technical Field

[0001] The utility model relates to the field of stepless height adjustment brackets, and particularly to a strong locking system and a quick release system for stepless height adjustment. Background Art

[0002] Stepless height adjustment brackets are widely used around the world for different purposes, such as working brackets, camera brackets, etc., such as a tripod with the authorized publication number of CN112856168B.

[0003] The most commonly used locking system is to fix the moving pipe with screws or clamp it with a chuck. In any case, the locking system is also a release system at the same time.

[0004] This means that the release system is always under load during use, which also means the rapid damage of the locking and release systems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a strong locking system and a quick release system for stepless height adjustment.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A strong locking system and a quick release system for stepless height adjustment, including a locking hole, a locking ring and a spring. The locking ring cooperates with the locking hole to enable the locking ring to swing up and down relative to the locking hole by a certain angle. The locking ring is in an inclined locking position under the push of the spring, and the moving pipe of the bracket is locked at any position on its moving length by generating an inclined moment through the inclined locking ring.

[0008] The inclined moment increases with the increase of the load. The greater the load, the greater the inclined moment.

[0009] Preferably, a locking tongue is provided on one side of the locking ring relative to the locking hole, and the spring is arranged on the other side of the locking ring relative to the locking tongue.

[0010] Preferably, the height of the locking hole is greater than the thickness of the locking tongue to enable the locking ring to swing up and down relative to the locking hole by a certain angle.

[0011] Preferably, the inner diameter of the locking ring is slightly larger than the outer diameter of the moving pipe, and the outer diameter of the locking ring is smaller than the inner diameter of the fixed pipe. When the locking ring is inclined, the moving pipe is locked relative to the fixed pipe.

[0012] Preferably, a fixed pipe cap is provided at the upper end of the locking ring, and the spring is sleeved on the fixed pipe cap.

[0013] Preferably, a release cam is further included, so that when the moving pipe is locked, the release cam is not in contact with the locking ring.

[0014] Preferably, the release cam is driven by a release lever. When releasing the lock, the release lever drives the release cam to rotate until the convex end abuts against the locking ring, and the locking ring is pushed to a position perpendicular to the moving tube. The moving tube descends freely without load.

[0015] Preferably, the release cam is arranged between the moving tube and the fixed tube, the release lever is arranged outside the fixed tube, and the release cam is connected to the release lever through a connecting rod passing through the fixed tube.

[0016] Preferably, the moving tube is slidably arranged in the fixed tube, the locking hole is arranged on the fixed tube, the fixed tube cap is installed on the fixed tube, and the moving tube passes through the fixed tube cap.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] The system of the present utility model can provide a higher load capacity. When the load is opened, the release system and the locking system do not contact; the release system only works when there is no load, and the release system is always not affected by the load force that may damage it.

[0037] Embodiment 1: A preferred embodiment of the present utility model provides a stepless height adjustment strong locking system and a quick release system, including a locking hole 1, a locking ring 2 and a spring 3. The locking ring 2 cooperates with the locking hole 1 to enable the locking ring 2 to swing up and down relative to the locking hole 1 by a certain angle. The locking ring 2 is in an inclined locking position under the push of the spring 3. By generating an inclined moment with the inclined locking ring 2, the moving tube 4 of the bracket is locked at any position on its moving length. And the inclined moment increases with the increase of the load. The greater the load, the greater the inclined moment.

[0038] A lock tongue 21 is provided on one side of the locking ring 2 relative to the locking hole 1, and the spring 3 is provided on the other side of the locking ring 2 relative to the lock tongue 21; the height of the locking hole 1 is greater than the thickness of the lock tongue 21 to enable the locking ring 2 to swing up and down relative to the locking hole 1 by a certain angle.

[0039] The inner diameter of the locking ring 2 is slightly larger than the outer diameter of the moving tube 4, and the outer diameter of the locking ring 2 is smaller than the inner diameter of the fixed tube 5. When the locking ring 2 is inclined, the moving tube 4 is locked relative to the fixed tube 5.

[0040] Embodiment 2: A preferred embodiment of the present utility model provides a stepless height adjustment strong locking system and a quick release system, and the difference from the above embodiment is only that: a fixed tube cap 6 is provided at the upper end of the locking ring 2, and the spring 3 is sleeved on the fixed tube cap 6;

[0041] The moving tube 4 is slidably arranged in the fixed tube 5, the locking hole 1 is arranged on the fixed tube 5, the fixed tube cap 6 is installed on the fixed tube 5, and the moving tube 4 penetrates through the fixed tube cap 6.

[0042] Embodiment 3: A preferred embodiment of the present utility model provides a stepless height adjustment strong locking system and a quick release system, and the difference from the above embodiment is only that: it further includes a release cam 7, the release cam 7 is arranged between the moving tube 4 and the fixed tube 5, the release lever 8 is arranged outside the fixed tube 5, and the release cam 7 is connected to the release lever 8 through a connecting rod penetrating through the fixed tube 5.

[0043] When the moving tube 4 is locked, the release cam 7 is not in contact with the locking ring 2.

[0044] The release cam 7 is driven by a release lever 41. When the lock is released, the release lever 41 drives the release cam 7 to rotate until the raised end abuts against the locking ring 2. The locking ring 2 is pushed to a position perpendicular to the moving tube 4, and the moving tube 4 descends freely without load.
