Specific embodiment

In order to illustrate more clearly of the technical solution of the utility model, attached drawing needed in description will be made below Simply introduce, it should be apparent that, the drawings in the following description are merely some embodiments of the present invention, for this field For those of ordinary skill, without creative efforts, it can also be obtained according to these attached drawings other implementations Example.

It is as shown in Figure 1, Figure 2, Figure 3 shows:

There are two the same body frames for the crane tool of the utility model.

Each body frame includes parallel upper frame 1 and chassis 14, and front swing arm 6 and rear-swing arm 7 are equipped between upper frame and chassis, preceding The both ends of swing arm 6 and rear-swing arm 7 are respectively hinged on upper frame 1 and chassis 14.

The upper end of extension spring 8 is hinged on front swing arm 6, extension spring 8 is made of 82B material.In front swing arm 6 with after 14 position of chassis between swing arm 7 has the mounting plate 15 holded up, and lateral lifting bolt 10 passes through the through-hole on mounting plate 15, The hanging ring 17 of lifting bolt 10 is located at the side of mounting plate 15, and there is hex nut 16 to be arranged in hanging ring for the other side of mounting plate 15 On bolt 15, the lower end of extension spring 8 is hooked on the hanging ring 17 of lifting bolt 10, is hung since 8 lower end of extension spring is hook-shaped Ring 17 is round, is hinged on hanging ring 17 namely is hinged on chassis 14 so extension spring 8 may be considered, due to stretching bullet The pulling force of spring 8, hex nut 16 are withstood on mounting plate 15, to limit the position of lifting bolt 10, and rotate adjusting hexagonal Nut 16 can adjust the position of lifting bolt 10 in through-holes, can adjust 8 length of extension spring, thus according to different weight Mattress 13 (providing for oneself in hotel) and bedstead 12 (providing for oneself in hotel), change push-pull effort and fall time size and speed.Push-pull effort Value can be controlled in 23Kg, and decrease speed is in 4~6s.

It is hinged with the upper end of damper 9 on rear-swing arm 7, what the lower end of damper 9 was hinged on chassis 14 is located at 6 He of front swing arm Position between rear-swing arm 7；Damper 9 is made of unidirectional oleo cushion.

The upper frame 1 of two body frames is arranged in parallel, and between two chassis 14 there is intermediate transverse tube 2 to connect between two upper frames 1 It connects.

Body frame and transverse tube 2 constitute a frame in this way.

Two upper frames 1 are equipped on Extension support 5 namely upper frame 1 in the same side and offer 7 adjustment holes, open on Extension support 5 Equipped with a location hole, there is positioning pin 51 to pass through location hole and wherein some adjustment hole, in this way, adjustable Extension support 5 The length of stretching, so that the total length of upper frame 1 and Extension support 5 is adjusted, for adapting to the mattress 13 of different length.

One aluminium T-type item 3 is fixed on the end of two Extension supports 5, and the horizontal stripe of T-type item 3 is fixed on Extension support 5, horizontal 30 end of item has the overhead gage 31 stretched out upward and the lower baffle plate 32 stretched out downward.

In the present embodiment, damper 9 is between T-type item 3 and extension spring 8.

Limited block 18 is equipped on chassis 14, limited block 18 and damper 9 are located at the two sides of rear-swing arm 7, and rear-swing arm 7 can push up It is against on limited block 18.Limited block 18 can prevent rear-swing arm 7 from tilting to the direction far from front swing arm 6, to draw bad stretching bullet Spring 8 and damper 9 cause the accident.

It is as shown in Figure 4, Figure 5:

12 lower part of bedstead has several cross bars 19 vertical with upper frame 1, there are several bedsteads to buckle 4, bedstead, which buckles 4, to be had downwards The slot 41 of opening and the coupler body 42 stretched out to side, in 19 embedded groove 41 of cross bar after, cross bar 19 is locked with the pin 42 across slot 41 In slot 41, coupler body 42 be hooked in the lower surface of upper frame 1 and make bedstead 12 and upper frame 1 connect namely bedstead 12 can not oneself to two Side is mobile and being detached from upper frame 1 oneself can not also start.After mattress 13 and bedstead 12 are placed on crane, overhead gage 31 blocks bed Pad 13.

Working principle of the utility model is:

It is preceding when the past pull-up of lower baffle plate 32 for catching on T-type item 3 in the T-type hand handle 11 that hook-shaped, top is T-type with bottom end bending The action reversed of swing arm 6 and rear-swing arm 7 and upper section rotates, and by mandril 1, up horizontal promoted arrives certain altitude, and worker can arrange Tidy up bed.

After having tidied up, apply one from rear-swing arm 7 towards the forward thrust in 6 direction of front swing arm, 13 He of mattress to mattress 13 The weight of bedstead 12 itself rotates front swing arm 6 and rear-swing arm 7, and at this moment extension spring 8 is elongated, and has started opposition pulling The slowly rotation decline of front swing arm 6, while damper 9 starts buffering and pushes, and withstands the slowly rotation decline of rear-swing arm 7, two upper frames 1 With the horizontal slowly decline of bedstead 12 and mattress 13, until dropping to minimum point.

Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other The difference of embodiment, the same or similar parts in each embodiment may refer to each other.To the upper of the disclosed embodiments It states bright, can be realized professional and technical personnel in the field or using the utility model.Various modifications to these embodiments pair It will be apparent for those skilled in the art, the general principles defined herein can not depart from this reality In the case where with novel spirit or scope, realize in other embodiments.Therefore, the utility model is not intended to be limited to this These embodiments shown in text, and it is to fit to the widest scope consistent with the principles and novel features disclosed herein.
