Specific embodiment

Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.

As Figure 1-Figure 4, a kind of people's air defense cement door leaf stirrup brake forming instrument, including handle 1, supporting block 2, positioning Hook 3, push rod 4, distributing reinforcement 01, principal rod 02 and stirrup 03；The distributing reinforcement 01 and 02 right-angled intersection of principal rod distribution；The hoop Muscle 03 is in the point of intersection of the distributing reinforcement 01 and principal rod 02 perpendicular to the distributing reinforcement 01 and principal rod 02；The supporting block 2 Top connect the handle 1；The push rod 4 and location hook 3 are respectively arranged at the both sides of the supporting block 2；

The location hook 3 includes the first location hook 31 and the second location hook 32；First location hook 31 and second positions Hook 32 is arranged in parallel；First location hook, 31 and second location hook 32 catches on the distributing reinforcement 01 and principal rod 02 respectively；

The lower surface of the push rod 4 is in 45 ° with the plane where the supporting block 2, location hook 3；The front end of the push rod 4 It withstands on the stirrup 03；

The contact point of first location hook, 31 and second location hook 32 and the distributing reinforcement 01 and principal rod 02 is respectively A And B, the contact point of the push rod 4 and the stirrup 03 is C；A, B, C any two points are apart from equal；The handle 1 is promoted, it is described Push rod 4 promotes the stirrup 03 to be rotated around the line of A and B；When the push rod rotates 45 °, the stirrup 03 rotates 135 °.

First location hook 31, the second location hook 32 and push rod 4 have collectively constituted a lever, due to A, B, C any two points Apart from equal, can be learnt by geometrical relationship plane where the first location hook 31, the second location hook 32 horizontal by 45 °, and the plane where the lower surface of push rod 4 and supporting block 2, location hook 3 is in 45 °, during using the line of A, B as shaft, when When handle 1 turns over 45 ° to plumbness, stirrup 03 bends 135 °, reaches necessary requirement.It can be reached first with the principle of lever To labour-saving purpose, consumption is not required to when bending stirrup 03 and is exertd great efforts.Secondly the first location hook 31, the second location hook are utilized 32nd, the geometrical relationship between push rod 4 and distributing reinforcement 01, principal rod 02 and stirrup 03 can be bent stirrup 03 with fast accurate Required angle, the bending of stirrup 03 are quicker.

Further description, the front end of the push rod 4 are equipped with arc slot 41, radius of curvature and the hoop of the arc slot 41 The outer diameter of muscle 03 is consistent.

In rotational handle 1, contact point C is moved at any time, and the front end of push rod 4 is set arc slot 41, can be to stirrup 3 Play the role of /V, it is ensured that push rod 4 will not take off power during rotation.

Further description, 31 and second location hook 32 of the first location hook include vertical portion 301 and bending part 302；The vertical portion 301 is connected with the supporting block 2；The vertical portion 301 is in 90 ° with the bending part 302；Described in two Bending part 302 is oppositely arranged.

The right angle that vertical portion 301 and bending part 302 form can make the first location hook 31 and the second location hook 32 is stuck in point In cloth muscle 01 and principal rod 02, and as the fulcrum rotated.Bending part 302 is oppositely arranged, and plays positioning action, when in use Facilitate and be once in place the first location hook 31 and the second location hook 32, be stuck on distributing reinforcement 01 and principal rod 02, convenient behaviour Make process.

Further description, the push rod 4 and vertical portion 301 are respectively arranged at front side and the rear side of the supporting block 2； The bending part 302 is arranged at the rear side of the vertical portion 301.

The plane where plane, the vertical portion 301, the plane where the supporting block 2 where the bending part 302 It offsets one from another with the plane where the push rod 4, distributing reinforcement 01 and principal rod is hooked to meet the location hook 3 in actual production While 02, push rod 4 can be with ejection stirrup 03.

Further description, the vertical portion 301 are radius of curvature and distributing reinforcement 01 with 302 junction of bending part The identical arc with principal rod 02.

Vertical portion 301 and bending part 302 for being stuck in distributing reinforcement 01 and principal rod 02, by vertical portion 301 with it is described curved It is processed into the radius of curvature arc identical with distributing reinforcement 01 and principal rod 02 in 302 junction of folding part, it is ensured that the first location hook 31 and second location hook 32 in rotation process can moment and distributing reinforcement 01 and principal rod 02 fit closely, place and slip.

Further description, the length of the handle 1 are no less than 80cm.

From lever principle, the length of handle 1 is longer, and when use is more laborsaving.By substantial amounts of it is demonstrated experimentally that working as handle When 1 length is no less than 80cm, worker does not have apparent laborious sensation in operation, and single worker can be grasped for a long time Make.

More than content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality With new thought, there will be changes, this specification content should not be construed as in specific embodiments and applications Limitation to the utility model.
