The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
As shown in Figure 1, a kind of suspension hook the utility model proposes, comprise pulley assembly 1 and coupler body 2, coupler body 2 is connected in pulley assembly 1 bottom, the end of coupler body 2 is provided with lock piece 3, be provided with locating part 11 on pulley assembly 1, lock piece 3 and locating part 11 coordinate to limit coupler body 2 around coupler body 2 self axis with respect to pulley assembly 1 rotation.
In the prior art, coupler body 2 normally can freely rotate, and the goods hung can drive coupler body 2 rotations due to the impact that is subject to external force.It is convenient for the hook block goods that coupler body 2 can rotate freely, and is also the convenient placed angle of adjusting during for arrangement of goods.Coupler body 2 can be realized freely rotating of 360 deg by thrust baring.The utility model is, in the end of coupler body 2, lock piece 3 is set, and fixes coupler body 2 and can not rotate relative to pulley assembly 1, has limited freely rotating of coupler body 2, has realized the locking to coupler body 2.Below will the concrete structure of lock piece 3 be further described.
As shown in Figure 2, lock piece 3 is for being placed on the cyclic structure of coupler body 2 ends, and the inner peripheral surface of lock piece 3 coordinates clamping with the outer peripheral face of coupler body 2 ends by internal tooth 31 and external tooth 41; Be formed with double wedge on the outer peripheral face of lock piece 3, locating part 11 is boss, and double wedge and boss are fixed.Lock piece 3 is realized fixing by internal tooth 31 and external tooth 41 interlocks of coupler body 2 ends self, makes coupler body 2 can not rotate with respect to lock piece 3.The boss arranged on pulley assembly 1, with the double wedge on lock piece 3, engage, make lock piece 3 can not rotate with respect to pulley assembly 1, cooperation by above-mentioned this structure, can make lock piece 3 can not relatively rotate with coupler body 2, can also make lock piece 3 take off from coupler body 2 easily simultaneously, taking off lock piece 3 when hanging article makes coupler body 2 can rotate to facilitate to hang, on the lifting fashionable dress, lock piece 3 blocks limited 11 of coupler body 2 and can not rotate to guarantee safety, thereby guarantees by stablizing in hoisting thing handling process.
Further, the mode that double wedge specifically is set can have multiple, for example, shown in an embodiment of the present utility model: be formed with a double wedge on the outer peripheral face of lock piece 3, locating part 11 comprises two boss, between these two boss, forms draw-in groove, and double wedge is limited to be connected in draw-in groove.Lock piece 3 coordinates and realizes clamping with two boss by a double wedge with 1 of pulley assembly, and mounting structure is simple, convenient disassembly.
In addition, as shown in Figure 3, in an embodiment of the present utility model, also list: double wedge is symmetrically formed on the outer peripheral face of lock piece 3 both sides, and locating part 11 comprises two boss, and two boss form the same side that is connected in two double wedges.The ，Cong both sides, both sides that boss is positioned at lock piece 3 are connected and fixed lock piece 3, have further increased the stability of lock piece 3, because two boss are positioned at the same side of double wedge, also make lock piece 3 when Assembly &Disassembly more for convenience.
Locating part 11 is formed on pulley assembly 1, and particularly, pulley assembly 1 comprises crossbeam 14, and boss shape is formed on crossbeam 14.Because coupler body 2 is connected on crossbeam 14, form locating part 11 and can make coupler body 2 relative with crossbeam 14 fixing on crossbeam 14; In addition, as shown in FIG. 1 to 3, can also be: pulley assembly 1 comprises left yoke plate 12 and right yoke plate 13, and boss shape is formed on left yoke plate 12 and/or right yoke plate 13.Left yoke plate 12 and right yoke plate 13 lay respectively at the both sides of crossbeam 14, boss shape is formed on left and right yoke plate 13 can play the effect that restriction lock piece 3 rotates equally, and the turning effort while having avoided coupler body 2 to rotate, crossbeam 14 applied, reduce the stressed of crossbeam 14, extended the service life of crossbeam 14.Below the matching relationship of locating part 11 and lock piece 3 is described further:
Only be formed with two boss on left yoke plate 12, between two boss, form draw-in groove; Be formed with a double wedge on lock piece 3, this double wedge can be connected between two boss; Perhaps, only on right yoke plate 13, form two boss, with the fit system of double wedge as left yoke plate 12.
As shown in Figure 2, can also be: be formed with two double wedges on lock piece 3, two boss shapes that can coordinate with one of them double wedge be formed on left yoke plate 12, and two boss shapes that coordinate with another double wedge are formed on right yoke plate 13; Certainly, as shown in Figure 3, can be also to form a boss on left yoke plate 12, backstop is lived a side of a double wedge, form a boss on right yoke plate 13, also backstop is lived a side of another double wedge, and two boss carry out backstop from the same side of two double wedges to lock piece 3, can realize latch functions equally.
In an embodiment of the present utility model, coupler body 2 comprises coupler body 2 is connected in to the hook nut 4 on pulley assembly 1, and lock piece 3 coordinates clamping with hook nut 4 by internal tooth 31 and external tooth 41.As shown in Figure 1, hook nut 4 normally is used for fixing the fastener of coupler body 2, forms external tooth 41 on the outer peripheral face of hook nut 4, makes lock piece 3 to engage with it by internal tooth 31, and then realizes fixing coupler body 2.In addition, by hook nut 4, also can avoid the direct wearing and tearing of 3 pairs of coupler bodies 2 of lock piece, extend the service life of coupler body 2.
In addition, the utility model embodiment has also proposed a kind of hoisting crane, comprises the suspension hook described in above-described embodiment.
The working process of the suspension hook that brief description once the utility model proposes:
The suspension hook the utility model proposes, by lock piece being socketed in to the end of coupler body, and coordinate with locating part and make that coupler body is fixing can not be rotated, guaranteed by the hoisting thing in the handling process steadily, avoided being collided by hoisting thing and other object damage or the personal injury caused, reduced by the hoisting thing because of the impact of rotation to weight-lifting equipment, also be conducive to by the accurate placement of hoisting thing simultaneously.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment, in reconcilable situation, can be combined by any suitable mode.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible array modes.
