6results about How to "Large height adjustment range" patented technology

A hydraulic support control box includes a base plate, a lifting assembly on the base plate, several limiting components on the base plate, and a fixing component on the lifting assembly. This utility model, as a hydraulic support control box, ensures the smoothness and reliability of the lifting process through its multi-stage transmission structure, effectively solving the problem of traditional support devices being unable to adapt to different pipe installation heights. The gear and rack meshing transmission method has high transmission accuracy and self-locking characteristics, which can stably maintain the adjusted support height and avoid displacement deviations caused by load changes. The entire mechanism, through modular design, converts linear motion into rotational motion and then back into linear lifting, achieving a large height adjustment range within a limited space, significantly improving the adaptability of the support device to different pipe diameters and installation conditions.

The utility model discloses a kind of lifting type feeding machines special for shaft production line, including rack, discharge bin is installed on rack, the rear end of discharge bin is provided with push opening, push opening is equipped with pusher, pusher includes several movable push plate and fixed push plate, movable push plate and fixed push plate are ladder type alternately distributed, drive device is further installed in rack, drive device is transmission connection with movable push plate.The utility model discloses feeding machine adopt lifting type structure design, by the synergic effect of multiple movable push plate and fixed push plate, gradually push shaft piece in discharge bin upwards, and via discharge plate to be conveyed to production line, the lifting height of feeding machine can be flexibly adjusted, can be through increasing or reducing push plate quantity or adjusting the stroke of movable push plate to satisfy actual use demand, so that feeding machine has greater height adjustment range, worker only needs to batch place shaft piece in discharge bin meeting ergonomics height, carrying strength is low, effectively improves feeding efficiency.

The utility model relates to the technical field of video equipment, in particular to multifunctional video equipment which comprises a display screen and a supporting assembly arranged below the display screen, the supporting assembly comprises a supporting frame, sliding rails are symmetrically and fixedly installed on the inner side surface of the supporting frame, an adjusting assembly is arranged between the two sliding rails, and a protection assembly is arranged on one side of the supporting frame. The protection assembly comprises a plurality of L-shaped rotating rods symmetrically and fixedly installed on the surfaces of the two sides of the supporting frame, rotating plates are rotationally connected to the outer sides of the L-shaped rotating rods, and a plurality of hinged protection plates are fixedly connected to one ends of the two rotating plates on the same side. According to the utility model, the height of the display screen is quickly reduced by moving the display screen downwards along the support frame, and then the display screen is shielded from the front of the display screen and protected by overturning the plurality of protection plates, and meanwhile, the gravity center of the display screen is reduced, so that the whole video equipment is more stable, and the video equipment is prevented from being toppled and damaged due to mistaken touch; and the protection effect of the video equipment is improved.

The utility model provides height convenient regulation's hydraulic support pole, including base frame, base frame is connected with the stand sleeve bottom end, hydraulic jack, hydraulic jack is installed in the bottom of stand sleeve inner chamber, telescopic stand, hydraulic jack top end is connected with telescopic stand through anti -rotation guide component, locking assembly, locking assembly is detachable with stand sleeve and telescopic stand connects respectively, top platform, top platform bottom and telescopic stand top end are connected, support head, support head bottom and support assembly are connected. The utility model's support pole's main part structure can cross project, cross segmentation infinite times repeatedly uses, and the loss rate of cushion block is extremely low, reduces the cost, realizes the reuse. Adopt hydraulic jack and carry out rough adjustment, locking assembly carries out locking fine adjustment, and height adjustment range is extensive and can be multi -granularity adjustment, can adapt to different linear type, different height's segmentation demand.

This utility model discloses an adjustable-height trimming device, comprising a shaft, a cylinder, and a blade. The shaft is located inside the cylinder, with a threaded rod integrally connected to its top. An adjusting nut is fitted onto the threaded rod, and a connecting kit is fixedly attached to the lower end of the adjusting nut. Rotating the adjusting nut drives the kit to move axially, thereby raising and lowering the blade. A locking nut is provided at the bottom of the shaft to fix the position after height adjustment. This utility model enables blade height adjustment to accommodate different specifications of suppository packaging. The adjustment process is simple and quick; operators can easily change the blade height using only a knob or handle on the adjusting device without replacing the entire trimming device, greatly improving production efficiency and flexibility. Furthermore, the device has a wide height adjustment range, meeting the production needs of various suppository specifications, further reducing production costs and complexity.

This utility model discloses a shoe with convenient height adjustment. The adjustable sole can be flipped back and forth based on the supporting sole. By changing the angle between the adjustable sole and the supporting sole, the heel height can be adjusted, supporting the heel of the foot at different heights. Support columns and pawls are respectively set on the supporting sole and the adjustable sole. The support column engages with the teeth on the pawl to form a ratchet mechanism. When worn, the entire height adjustment process does not require standing on one leg. Adjusting to decrease the height is relatively simple, and adjusting to increase the height does not even require using hands. This effectively solves the problem of inconvenient heel height adjustment in current shoes, reducing the operational difficulty of height adjustment and improving the practicality and safety of this convenient height-adjustable shoe.
