Abstract
The utility model relates to a hand-lock support rod of a tip-up door; a support is connected with a slide tube through a lower pin shaft; a locking claw and the slide tube are fixed together as a whole; a manual locking nut on the locking claw is connected with the locking claw; a slide rod is arranged in the slide tube; the tail end of the slide rod which is arranged in the slide tube is provided with a positioning groove; and an upper pin shaft is connected with the slide rod. The hand-lock support rod of the tip-up door is in a full-mechanical structure, is operated manually, avoids all pneumatic and hydraulic elements, the locking claw is made of a hard material, the concentricity of the slide rod and the slide tube is ensured, so that the eccentric wear of the slide rod and the guide tube is greatly weakened, the service life of easily consumable parts is prolonged, the phenomenon that the support rod fails to work caused by a seal element is eliminated, and the hand-lock support rod of the tip-up door has the characteristics of light weight, low cost, convenience in installation and adjustment, convenience in part replacement, good shape and the like.
Description
Technical field
The utility model 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 utility model purpose is that 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 will be provided.
The purpose of this utility model is achieved in that 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.
The tilt-up door hand lock support bar that the utility model provides, 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 utility model.
Fig. 2 is a locking jaw structural representation of the present utility model.
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 utility model 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.
