Abstract
The invention discloses a hand-locking type support rod of a tip-up door. A support is connected with a sliding cylinder through a lower hinge pin; a locking jaw is integrally fixed with the sliding cylinder; a hand locking nut on the locking jaw is connected with the locking jaw; a sliding rod is mounted in the sliding cylinder; a positioning groove is arranged at the tail end of the sliding rod in the sliding cylinder; and an upper hinge pin is connected with the sliding rod. The hand-locking type support rod of a tip-up door provided by the invention adopts a full-mechanical structure, is manually operated and saves all pneumatic and hydraulic elements; as the locking jaw is made from a hard material, the concentricity between the sliding rod and the sliding cylinder is ensured, eccentric wear between the sliding rod and a guide cylinder is reduced to a great degree, the service life of the easily-damaged parts is prolonged, and the failure of the support rod caused by a sealing element is eliminated; and moreover, the hand-locking type support rod has the characteristics of light weight, low cost, good shape and the like, and is convenient to install and adjust and to replace the components.
Description
Technical field
The present invention relates to a kind of manual locking supporting mechanism that is used for tilt-up door, particularly a kind of tilt-up door hand lock support bar that is applicable to large-scale skid mounted equipment.
Background technology
In present tilt-up door supporting mechanism, general employing air spring or small-sized hydraulic cylinder are realized.Because hydraulic drive need be equipped with a cover small-sized hydraulic station, often safeguard to hydraulic system that so cost in actual use, is used less than higher; And air spring is in long-term use, and eccentric wear can take place guide peg, and seal is subjected to the influence of environment temperature bigger, seal will lose efficacy after causing using a period of time, make the air spring gas leakage, cause the air spring opening and closing ineffective, even can not work.
Summary of the invention
The present invention seeks to provide a kind of alternative air spring or small-sized hydraulic cylinder, compact conformation, tilt-up door hand locking-type support bar esy to use, safe and reliable.
The object of the present invention is achieved like this: a kind of tilt-up door hand locking-type support bar, bearing is connected with slide cartridge by lower bearing pin, locking jaw and slide cartridge are fixed as one, manual locking nut on the locking jaw is connected with it, slide bar is installed in the slide cartridge, the end of slide bar in slide cartridge has detent, and upper pin is connected with slide bar.
Tilt-up door hand lock support bar provided by the invention, adopt full mechanical, manual operation, avoid all pneumatic, Hydraulic Elements, locking jaw adopts hard material, has guaranteed the concentricity of slide bar and slide cartridge, weakened the eccentric wear of slide bar and guide to a great extent, increased the application life of consumable accessory, eliminated the support bar failure phenomenon that causes because of potted component, and have light weight, cost low, be convenient to install and adjust, be convenient for changing characteristics such as parts and moulding are good.
Description of drawings
Fig. 1 is a stereogram of the present invention.
Fig. 2 is a locking jaw structural representation of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, a kind of tilt-up door hand locking-type support bar, bearing 1 is connected with slide cartridge 3 by lower bearing pin 2, locking jaw 4 is fixed as one with slide cartridge 3, manual locking nut 5 on the locking jaw 4 is connected with it, slide bar 6 is installed in the slide cartridge 3, and the end of slide bar 6 in slide cartridge 3 has detent, and upper pin 7 is connected with slide bar 6.Described locking jaw 4 leaves the gap stay each other by four and constitutes.
Operating principle of the present invention is as follows: bearing 1 is fixed on the doorframe of tilt-up door, and upper pin 7 links together slide bar 6 and tilt-up door.
When needs are opened tilt-up door, 7 liang of hinges of locating of lower bearing pin 2 and upper pin can make the tilt-up door support bar, automatically adjust angle along with opening gradually of tilt-up door, slide bar 6 can stretch out for 3 li from slide cartridge under the guiding of locking jaw 4 gradually simultaneously, after tilt-up door is opened to suitable height, it is female 5 manually to tighten locking, makes locking jaw 4 uniformly and slide bar 6 lockings, utilize locking jaw 4 and slide bar 6 tail ends groove finish locking function.
When needs are closed tilt-up door, manually unclamp locking female 5, locking jaw 4 automatically resets, break away from slide bar 6, slowly put down tilt-up door, 7 liang of hinges of locating of lower bearing pin 2 and upper pin can make the tilt-up door support bar, adjust angle automatically along with closing gradually of tilt-up door, slide bar can be withdrawn in the slide cartridge 3 under the guiding of locking jaw 4 gradually simultaneously, closes fully up to tilt-up door.
