Abstract
The utility model provides a large box fastening device for transportation. The large box fastening device comprises a fastening screw, wherein a rod of the fastening screw is sleeved with a stepped sleeve with a cap, the stepped sleeve is sleeved with a compression sleeve, a pull ring is nested on the stepped sleeve between a cap end of the stepped sleeve and the compression sleeve, and a screw hole and a positioning hole matched with the fastening screw and the stepped sleeve are formed in a box; the stepped sleeve sequentially comprises the cap end, a cylindrical section and a long round section; the cylindrical section is matched with the compression sleeve in length; and the long round section corresponds to the positioning hole in the box, and the positioning hole is also a long round hole matched with the long round section. During use, the screw firstly is penetrated into a middle hole in the stepped sleeve, then, the pull ring and the compression sleeve are penetrated into an excircle of the stepped sleeve, the whole device is taken as a whole, part of the long round section of the stepped sleeve is inserted into the corresponding position of the stepped hole in the surface of the box, the screw is tightened, and at the same time, a gap is reserved between the bottom of the stepped sleeve and the bottom of a pre-drilled hole in the box, so that the bottom of the compression sleeve can be tightly attached to the outer surface of the box, the compression sleeve, the pull ring and the stepped sleeve are mutually compressed, then tensile force acts on the pull ring, and the box is fastened.
Description
Technical field
The utility model relates to large-size box or equipment securing means, refers to particularly a kind of large-size box transhipment securing means.
Background technique
Due to the reprinting requirement of casing storing goods and materials, usually need large-size box to be transported to destination by various transportation means, because box sizes is large, when transport, easily produce play, need a kind of securing means reliably.At present, casing is fixed on to mode on means of transportation of a great variety, the wire rope that has conventionally adopting directly interts screw rod on fastening, the casing of binding, and the outside design frock of, casing fastening by traction screw realizes fastening etc. indirectly by fastening device.But wire rope is fastening stressed larger, may cause damage to tank surface; Intert traction screw because screw diameter is little, once screw rod fracture failure, fastening failure; Fabricating tools requires every kind of casing to manufacture one, and the manufacturing cycle is long, expends larger.As can be seen here, above these securing meanss are not well positioned to meet reliable easy fastening requirement on large-size box means of transportation.
Summary of the invention
The purpose of this utility model will provide a kind of large-size box transhipment securing means exactly.It can meet various large-size boxes completely and transport fastening requirement.
The technical solution of the utility model: a kind of large-size box transhipment securing means of the present utility model comprises fastening screw, on the bar of fastening screw, cover has the ladder bushing with cap, on ladder bushing, cover has clamping sleeve, draw ring is enclosed within on the ladder bushing between cap end and the clamping sleeve of ladder bushing, has the screw and the positioning hole that mate with fastening screw and ladder bushing on casing.
Described ladder bushing comprises cap end, cylindrical section, oval section successively; Cylindrical section is corresponding with clamping sleeve; Oval section corresponding with the positioning hole on casing, and positioning hole is also and the oval section of slotted hole mating.
Advantage of the present utility model: when carrying out casing when fastening, due to restriction and the Step Shaft problem of stress concentration of tapped hole, screw diameter size is fixed, if power directly acts on helical thread portion, also can produce to scratch due to the stressed easy-rupturing of helical thread portion, and to tank surface and draw.Masterpiece of the present utility model, for ladder bushing, has increased the active area of power, and unit area is stressed little, has disperseed part power.
Clamping sleeve is enclosed within on a hollow large straight step sleeve; screw rod only plays a positioning action here; ladder bushing bears most shearing force; because ladder bushing diameter is large; good rigidity, and inner hollow, increased lifting surface area; the effect of having shared shearing force in saving material, can not cause damage to tank surface when having protected positioning screw yet.
Concrete advantage is mainly manifested in the following aspects: one, number of spare parts is few, simple in structure, easy to operate, when use without other instrument, reliable operation.Its two, there is the effect of protection positioning screw, make fastening pulling force act on outer sleeve, middle part screw rod does not stress, and can ensure fastening reliable.Its three, can play a protective role to tank surface, fastening pulling force does not act on casing or positioning screw, casing can be realized not damaged.Its four, have good extendable functions, according to aperture, different casing location, it is carried out to seriation and combine design, to meet the fastening requirement of different size casing.Its four, be not subject to the restriction of field of employment, be suitable for various large-size boxes nearby, fast, reliably fastening.
Brief description of the drawings
Fig. 1 is a kind of large-size box transhipment securing means structural representation.
Fig. 2 is the perspective view of ladder bushing in Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is a kind of large-size box transhipment securing means structural representation: the utility model comprises fastening screw 1, on the bar of fastening screw 1, cover has the ladder bushing 2 with cap, on ladder bushing 2, cover has clamping sleeve 3, draw ring 4 is enclosed within on the ladder bushing 2 between cap end and the clamping sleeve 3 of ladder bushing 2, has the screw 7a and the positioning hole 7b that mate with fastening screw 1 and ladder bushing 2 on casing 7.
Fig. 2 is the perspective view of ladder bushing in Fig. 1: described ladder bushing 2 comprises cap end 2a, cylindrical section 2b, oval section of 2c successively; Cylindrical section 2b is corresponding with clamping sleeve 3; Oval section of 2c is corresponding with the positioning hole 7b on casing 7, and positioning hole 7b is also the slotted hole mating with oval section of 2c.
Screw rod 1 is conventional hexagonal-head screw rod, and its thread size is determined by preboring tapped hole size on casing, plays a part to locate in tank surface.
The form that ladder bushing 2 rear portions are cylindric Step Shaft, has excessive fillet with end face, avoids stress to concentrate.Ladder bushing 2 is the main bearing member of pulling force, has certain requirement of strength, and anterior oval section of 2c can make sleeve fixing in casing, avoided radial rotating, and middle part penetrates positioning screw, has effectively protected screw rod.
Clamping sleeve 3 and draw ring 4 are enclosed within on ladder bushing 2, are fixed on cabinet exterior, and pulling force can be decomposed into the pressure vertical to tank surface and the shearing force to sleeve, have reduced the wearing and tearing of sleeve and the damage to tank surface.
When the utility model uses, first by screw rod 1, comprise that compression spring 6 and plain washer 5 penetrate in ladder bushing 2 mider holes, again draw ring 4 and clamping sleeve 3 are penetrated to ladder bushing 2 cylindricals, then whole device is as a whole by the oval section of 2c partial insertion casing 7 7b relevant positions, surface step hole of ladder bushing 2, tighten again screw rod 1, note leaving space bottom ladder bushing 2 bottoms and casing pre-drilled simultaneously, thereby casing 7 outer surfaces are close in guarantee clamping sleeve 3 bottoms, and clamping sleeve 3, draw ring 4 and ladder bushing 2 compress mutually.This back pull acts on draw ring 4, and casing is fastening.
Remove the time receiving, first unclamp screw rod 1, whole device is pulled down from casing 7, then remove successively clamping sleeve 3, draw ring 4 and ladder bushing 2, compression spring 6 and plain washer 5, complete and remove receipts.
