CN203653063U - Lifting spring - Google Patents

Abstract

The utility model provides a lifting spring which is simple in structure, wear-resistant, difficult to damage and convenient to mount and replace and can achieve the effects of shock absorption and noise reduction. The lifting spring comprises a support, wherein a U-shaped lifting ring is connected to the lower side of the support; a through hole is formed in the middle of the support; a lifting hook penetrates through the through hole, and a spring and a spring seat are sleeved below the support; a thread and a locking nut are arranged at the tail end of the lifting hook.

Description

Hang spring

Technical field

The utility model relates to the field of components of feeding device, is specially and hangs spring.

Background technology

At precoated sand, during reclaimed sand etc. are produced, need to use feeding device to feeding equipment feeding, for example, from sand storage, in vibro-crusher, deliver molding sand, or quantitative machine is delivered molding sand to the equipment of subsequent processing, it is higher that its sand export often arranges, between sand export and feeding equipment, distance is crossed can scatter contaminated environment cause waste of molding sand that conference causes transmitting, also can cause greater impact to damage feeding equipment to feeding equipment, vibration feeder can be suspended on to designated equipment below and reduce sand drop, reduce impulsive force, while work due to vibration feeder in always in vibrational state, if use the common hook can be due to the excessive damage equipment of frequent vibration amplitude, can produce very large noise simultaneously.

Utility model content

For the problems referred to above, the utility model provides and has hung spring, and it is simple in structure, can play the effect of damping, noise reduction, wear-resisting not fragile, and it is convenient to install and change.

The technical solution of the utility model is such: it is characterized in that: it comprises bearing, the below of described bearing is connected with U-shaped suspension ring, through hole is set in the middle of described bearing, suspension hook is through described through hole and below described bearing, be set with spring and spring perch, and the tail end of described suspension hook is provided with screw thread and is provided with jam nut.

It is further characterized in that: described jam nut is provided with two;

Described U-shaped suspension ring connect described bearing by nut.

The beneficial effects of the utility model are: on suspension hook, add spring and can play damping, Noise Reduction, it is simple in structure, and wear-resisting not fragile, U-shaped suspension ring connect bearing by nut, and it is convenient to install and change.

Brief description of the drawings

Fig. 1 is main TV structure schematic diagram of the present utility model;

Fig. 2 is side-looking structural representation of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described further.

See Fig. 1 to Fig. 2, the utility model comprises bearing 1, the below of bearing 1 is connected with U-shaped suspension ring 2, the centre of bearing 1 arranges through hole, suspension hook 3 is through through hole and below bearing 1, be set with spring 4 and spring perch 5, on the tail end of suspension hook 3, work screw thread is provided with jam nut 6, and jam nut 6 is provided with two, and U-shaped suspension ring 2 connect bearing 1 by nut 7.

On suspension hook 3, add spring 4 and can effectively reduce friction force and wear intensity, on the other hand, the vibratory force that makes to be delivered on cell body obviously weakens, there is the effect of obvious shock dropping noise abatement, it is simple in structure, wear-resisting not fragile, U-shaped suspension ring 2 connect bearing 1 by nut 7, and it is convenient to install and change.

Claims (1)
