Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Detailed description, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole implementation Example.Based on the embodiment in the utility model, those of ordinary skill in the art institute on the premise of creative work is not made The every other embodiment obtained, belongs to the scope of the utility model protection.

With reference to shown in Fig. 1-3, the derrick crane being easily installed, including large arm, it is many that large arm includes that head and the tail are connected Individual linking arm 100, two adjacent heads of linking arm 100 support afterbody, and the head lower end of linking arm 100 has protruded outward multiple One bayonet lock 110, the afterbody lower end of linking arm 100 is concaved with the groove 120 for coordinating multiple first bayonet locks 110, the tail of linking arm 100 Portion upper end has protruded outward the first plate body 130 and the second plate body 140, and the first plate body 130 is relative about 140 with the second plate body to be set Put, the first plate body 130 offers mutual corresponding first through hole 150, the first plate body 130 and second respectively with the second plate body 140 A grasping part 160 is formed between plate body 140, the head of linking arm 100 protrudes outward the 3rd plate for coordinating grasping part 160 Body 170, the 3rd plate body 170 offers the second through hole of correspondence first through hole 150, in addition to the second bayonet lock 190, the second bayonet lock 190 correspond to the through hole of first through hole 150 and second, and the bottom of the second plate body 140 is provided with a stage portion 200, the tail of the second bayonet lock 190 End is held on stage portion 200.

By the first bayonet lock and groove, the second bayonet lock docks with through hole, you can conveniently realize the assembling of linking arm, and And mutually supported between linking arm, it is that integrally-built consolidate can be achieved by self gravitation.

Further, the 3rd plate body 170 is held in grasping part 160.The t shape of second bayonet lock 190.

It is held in after grasping part, the second bayonet lock t shape, bottom is first staggered with stage portion when such bayonet lock is inserted, Complete to insert after rear second bayonet lock itself rotation, the afterbody of the second bayonet lock is held on stage portion, so that overall structure is more Plus it is firm, the second bayonet lock can be clamped by self gravitation, it is sufficiently stable.

Further, the second plate body 140 is connected with a chain 210, and chain 210 is connected to the bottom of the second bayonet lock 190.

It can ensure that the second bayonet lock is not lost when single-piece is transported, because the second bayonet lock is relatively small, be very easy to lose.

Further, the afterbody of linking arm 100 is provided with a mobile security button 180.

Operating personnel ensure that safety when operating.
