Abstract

The utility model relates to a rotary regulating screw joint, which is composed of a connecting rod, a fixing device, U-shaped iron and a connecting pin, wherein, the fixing device comprises a standby anchor nut, a check baffle ring, an end plug and a hexagon nut uniformly distributed with gaps at a top and provided with a sleeve at a tail. In assembly, the sleeve of the hexagon nut passes through the top circular hole of the U-shaped iron and then the end plug is welded up to clamp the U-shaped iron. Then the connecting rod penetrated with the standby anchor nut and the baffle ring passes through the hexagon nut already connected with the U-shaped iron into integration. If the hexagonal nut is rotated, the U-shaped iron can move right and left to change the space of the screw joint. Finally, the hexagon nut is clamped and jammed by the baffle ring and the standby anchor nut, so that the screw joint can be firmly fixed.

Description

Rotatable regulating type spiral shell snapping head

The utility model relates to a kind of rotatable regulating type spiral shell snapping head, belongs to a kind of general mechanical connection accessory.

Existing spiral shell snapping head unit, as shown in Figure 1, comprising connecting rod 1 ', be equipped with jack panel 2 ', U-iron 3 ' be connected pin 5 and constitute, wherein connecting rod 1 ' an end be connected with an equipment, the other end in succession U-iron 3 ', U-iron 3 ' the other end be connected with another equipment with pin 5, interconnect coacting purpose thereby reach two equipment.But this joint when reality is used, often needs according to the equipment requirement, to its rod member lengthening or shortening.On railway switch, connect the spiral shell snapping head that uses on two tip of a root rail front rod of a point and be example, when need change between two points of switch apart from the time, at first cotter pin 4 must be pulled out, take down connection pin 5 again, the bar 1 that is rotationally connected ' or U-iron 3 ', make and reach correct position, pin 5 is loaded onto, this work is during site operation again, the equipment because rod member is all ined succession, mutual extrusion is very tight, the bar 1 that is rotationally connected ' or U-iron 3 ', very painstaking, and in the process that penetrates pin 5, because pitch-row displacement is difficult to align, so during construction, often need a human crowfoot thick stick to rise and withstand tongue, another human hammer knocks pin 5, must operate simultaneously more than two people, but after installing, sometimes still improper, pin must be pulled down, from the beginning rise, sometimes will be repeatedly several times; Especially, current train operation density is big, and the engineering time is very urgent, adjusts one time connecting rod length, and is very difficult.

The purpose of this utility model is that a kind of rotatable regulating type spiral shell snapping head will be provided, and uses its connected element, does not need dismounting to connect pin, can easily change the length between connected element, thereby time saving and energy saving.

The purpose of this utility model is achieved in that rotating regulation type spiral shell snapping head, by connecting rod, fixing device, U-iron be connected pin and constitute, include jack panel fully in the fixing device, locking baffle ring, the top has hexagon nut and the plug that uniform gap afterbody has oversleeve, during assembling, the oversleeve of hexagon nut is passed U-iron top circular hole, the plug of burn-oning immediately, U-iron is clamped, then will be installed with the connecting rod that is equipped with jack panel and baffle ring, pass the hexagon nut that fuses with U-iron, the rotation hexagon nut, U-iron is a move left and right and change spiral shell snapping head spacing, utilize baffle ring at last and be equipped with jack panel, make spiral shell snapping head firmly motionless the stuck jam-packed of hexagon nut.

The utility model advantage:

1, regulate spiral shell snapping head length degree, convenient and strength-saving: as to use the utility model connected element, when between change portion during length, because of not needing dismounting to connect pin, drive the U-iron move left and right and get final product and only rotate hexagon nut that the U-iron top has a gap, reach requirement length during adjustment easily, the while is because of using locking baffle ring, make and adjust in case after finishing, spacing on the connecting rod, malleable not, thus greatly raise labour efficiency, alleviate labor strength, and guarantee that Plant in good condition is harmless; Use on railway switch, according to statistics, adopt the utility model to regulate spiral shell snapping head length when spending, manpower can save 50%, and the time can be saved 70-80%, takies train off time when reducing construction, helps safe driving.

2, simple in structure, promote easily: because of only needing that U-iron top screw in the former spiral shell snapping head is processed into big slightly smooth circular hole, after the oversleeve of band gap hexagon nut passed the circular hole of U-iron, the plug of burn-oning in the oversleeve end made first clamping of itself and nut U-iron top, in addition, baffle ring groove and locking baffle ring are set up in processing slightly on connecting rod, the threaded end of connecting rod is screwed in the hexagon nut that has been fixed on the U-iron, i.e. assembling is finished.This structure just can reach locking with simplify to regulate connecting rod on be connected the purpose of length, so promote easily be used in various relevant equipment on.

The utility model concrete structure is provided by following examples and accompanying drawing thereof:
