Abstract
The utility model discloses a screw rod locking nut. The screw rod locking nut comprises a nut body. The nut body comprises two correspondingly buckled semicircular components. The two ends of each semicircular component are respectively and radially provided with a flange in a protruding mode. The two semicircular components are connected and fixed through bolts or screws arranged between the flanges. Inner threads are correspondingly formed in a circular hole defined by the two semicircular components. According to the screw rod locking nut, the flanges are radially arranged at the ends of the two semicircular components, and the two semicircular components are connected as a whole through the screws installed in a screwed mode or the bolts arranged in a penetrating mode between the opposite flanges; as a split structure is adopted, when a screw rod needs maintenance, the locking nut can be detached as long as the bolts or the screws connected between the opposite flanges are loosened, time and labor are saved, and the problem that an existing locking unit is difficult to detach is solved.
Description
Technical field
The utility model relates to a kind of screw mandrel locking nut.
Background technique
Existing screw axis adopts ring nut to adjusting locking nut, and the spaced apart opening that is provided with on the outer circumferential face of this nut, by special opening clamp rotation lock.But the locking nut of this ring in use often can be because difficulty is dismantled in wearing and tearing, sometimes also must employ oxygen cutting and tear down, labor intensive material resources, also can incur loss through delay the device maintenance time, cause plant maintenance time-consuming.
Model utility content
The purpose of this utility model is: provide a kind of easy to use, dismantle screw mandrel locking nut efficiently, dismantle difficult problem to solve existing locking nut.
The technical solution of the utility model is: a kind of screw mandrel locking nut, comprise nut body, described nut body comprises two corresponding semi-circular members that fasten, at the two end part of two halves round member respectively radially convex with flange, two halves round member is connected and fixed by the bolt or the screw that arrange between opposing flanges, and in the circular hole surrounding at two halves round member, correspondence is provided with internal thread.
Screw mandrel locking nut of the present utility model is, in the end of two semi-circular members, flange is radially set respectively, by the screw of spinning in opposing flanges or the nut wearing, two semi-circular members are connected as a single entity, because this screw mandrel locking nut has adopted Split type structure, in the time that screw mandrel need to be safeguarded, only need unclamp the bolt or the screw that between opposing flanges, connect can pull down locking nut, time saving and energy saving, solve existing locking nut and dismantled difficult problem.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model screw mandrel locking nut.
Embodiment
The specific embodiment of screw mandrel locking nut of the present utility model as shown in Figure 1, this screw mandrel locking nut comprises two corresponding semi-circular members 1,2 that fasten, other radial convex of two end portions at two halves round member 1,2 is provided with flange 3,4, between the relative flange 3,4 of two halves round member 1,2, offer the through hole communicating, two halves round member 1,2 is fixedly connected with by the bolt 5 being arranged in relative two flange 3,4 through holes, and two halves round member 1,2 is connected as one.On the intrados of two semi-circular members 1,2, partial thread is set respectively, when two halves round member 1,2 is connected and fixed while being integrated, the partial thread on two halves round member 1,2 forms complete internal thread 6.
When use, by two bolts 5, two semi-circular members 1,2 are connected and fixed to composition screw mandrel locking nut, screw on screw mandrel and realize and being locked by the internal thread arranging in two halves round member 1,2.When dismounting, only need unclamp two bolts 5, this screw mandrel locking nut can be taken out, dismantle very convenient.
In two halves round member 1,2 can also be by relative two flanges 3,4, the screw of spinning is connected and fixed.
