Abstract

The utility model belongs to the field of mechanical design, and relates to a clamping device, in particular to a hoop which comprises an accessory clamping piece, a connection hook, an adjustment hook, an adjustment nut and a chain. One end of the connection hook is fixed to the accessory clamping piece, and the other end of the connection hook is hooked in the gap between chain links at one end of the chain; one end of the adjustment hook is hooked in the gap between chain links at the other end of the chain, and the other end of the adjustment hook penetrates through a through hole in the accessory clamping piece; the adjustment nut is screwed at the threaded end of the adjustment hook, and the adjustment nut is screwed down to clamp an accessory. Through matching of the chain, the adjustment hook and the adjustment nut, the hoop can be connected with accessories of various irregular shapes and various sizes, due to the characteristics of multiple chain links and high strength of the chain, the hoop can be adaptive to high-strength connection and connection under the working station of narrow installation space, and the hoop is simple in structure, easy to install and high in adaptability.

Description

A kind of clip

Technical field

The utility model belongs to mechanical design field, relates to a kind of holding device, particularly relates to a kind of clip.

Background technique

In Machine Design and assembling field, often need a kind of link of clip class, be used for minor attachment to be fixed on by attached parts, all generally design specialized fixtures, one end is held on by attached parts, the other end is fixed minor attachment, in such cases, special fixture need to by attached parts external form, be harmonious, and combined by my part, the fastening pieces such as portion's bolt connect and are fastening, for different by annex, just need to design different fixtures, meanwhile, while running into narrow space, the design of fixture is just very complicated, and installment work also can be extremely difficult.In such cases, just need a kind of general can self adaption by the clip of annex, be used for meeting different from annex profile and different operating mode, especially by annex in narrow space, plain clamp is because shape is fixed and cannot realize the problem of installation.

In addition, disclose a kind of clip at application number in the patent that is 98247128.9, by steel band, screw and two upper and lower cylinders form, and screw through in the tapped hole of upper and lower cylinder, regulates the spacing of two cylinders to control the size of clip by bolt successively.The steel band length that this kind of clip relates to is fixed, cannot adapt to various shapes by annex, meanwhile, due to the flexibility of steel band itself and the contradiction of intensity, cannot be adapted to high strength and irregular contour by the connection of annex.

Summary of the invention

The purpose of this utility model is: a kind of clip is provided, can be adapted to various irregular contours and various sizes by annex, and can use within high join strength connects operating mode, narrow installing space under operating mode.

The technical solution of the utility model is: a kind of clip, comprise accessory clamp gripping member 1, and butt hook 2, adjustable hook 4, adjusting nut 5, chain 3, butt hook 2 one end are fixed in accessory clamp gripping member 1, and another end hook is in the chain link gap of chain 3 one end; Adjustable hook 4 one end hooks are in the chain link gap of chain 3 the other ends, and the other end is through the through hole of accessory clamp gripping member 1, and adjusting nut 5 is spun on the threaded end of adjustable hook 4.

Described chain 3 is simplex roller chain.

By increasing or reduce the chain link quantity of chain 3, realize the coarse adjustment to clip size, by rotation adjusting nut 5, realize the fine setting to clip size.

The beneficial effects of the utility model: the utility model is by the cooperation of simple chain and adjustable hook and adjusting nut, realization is connected by annex with various irregular contours and various sizes, multi-joint and high-intensity characteristic due to chain, can be applicable to the connection under operating mode in high join strength connection and narrow installing space, simple in structure, be easy to install strong adaptability.

Accompanying drawing explanation

Fig. 1 is the structural principle schematic diagram of a kind of clip of the utility model;

Fig. 2 is that the utility model is for the principle schematic of hydraulic cylinder piston rod displacement measurement sensor clamping;

Wherein, 1-accessory clamp gripping member, 2-butt hook, 3-adjustable hook, 4-adjusting nut, 5-chain, 6-displacement measurement sensor, 7-hydraulic jack.

Embodiment

Below in conjunction with Figure of description, the utility model is described in further detail.Refer to Fig. 1 to Fig. 2.

As shown in Figure 1, a kind of clip, comprises accessory clamp gripping member 1, butt hook 2, and adjustable hook 4, adjusting nut 5, chain 3, butt hook 2 one end are fixed in accessory clamp gripping member 1, and another end hook is in the chain link gap of chain 3 one end; Adjustable hook 4 one end hooks are in the chain link gap of chain 3 the other ends, and the other end is through the through hole of accessory clamp gripping member 1, and adjusting nut 5 is spun on the threaded end of adjustable hook 4.Described accessory clamp gripping member 1, for annexes such as clamping liquid compressing cylinders, clamps annex by superincumbent screw is set.Butt hook 2 is fixed on accessory clamp gripping member 1 one end by the mode such as welding or be spirally connected.

Described chain 3 is simplex roller chain.Simplex roller chain has good rigidity on the one hand, on the other hand, by the chain link of some quantity on dismounting simplex roller chain, realizes the coarse adjustment to clip size, needs fine setting to be, by rotation adjusting nut 5, realizes the fine setting to clip size.

Embodiment one:

The present embodiment is to use the utility model clamping hydraulic cylinder piston rod displacement measurement sensor, and displacement transducer 6 is fixed in accessory clamp gripping member 1, and butt hook 2 one end are fixed in accessory clamp gripping member 1, and another end hook is in the chain link gap of chain 3 one end; Chain 3 is walked around hydraulic jack 7, and is connected with adjustable hook 4 one end, and adjustable hook 4 the other ends are logical through the hole of accessory clamp gripping member 1, and adjusting nut 5 is spun on to the threaded end of adjustable hook 4, screws and regulates spiral shell 5 mothers just to realize the clamping to displacement testing sensor 6.

Further, when chain 3 length are not mated with hydraulic jack 7 girths, can make chain 3 length roughly identical with hydraulic jack 7 girths by increasing or reduce chain link quantity, then clamp by screwing adjusting nut 5.
