Abstract
The utility model relates to a locknut. The locknut comprises a hollow tubular main body, wherein an inner wall at the top end of the main body protrudes outwards, takes the shape of an arc and forms a stop part; internal threads are arranged in the inner wall of the main body; and at least one lug is arranged on the stop part. In the nut disclosed by the utility model, when the waterproof connector is rotated out, an inner jaw is not easy to slip off under the clamping action of the stop part; and the nut has the advantages of simple structure and low cost.
Description
Technical field
The utility model relates to a kind of nut, relates in particular to a kind of nut that prevents mold release function that has.
Background technique
The fixed structure of existing cable and fixed block (as terminal box) generally comprises nut, interior pawl, plug and water joint, during use, to put cable to be fixed successively with upper member, the internal thread of nut is screwed in the outside thread of water joint, up to locking, when pawl cooperates with nut in utilizing, and under the thrust of water joint, the internal pawl of the circular arc inwall on nut top produces compressing, the clamp jaw of interior pawl clamps cable, interior pawl props up the circular arc inwall on nut top, thereby cable is fixed.The effect of plug and water joint is waterproof.
Wherein, the inwall on plain nut top is circular arc to outer lug, forms backstopping assembly.When interior pawl is placed in this plain nut, along with the locking gradually of nut and water joint, the backstopping assembly that utilizes nut compresses each clamp jaw of interior pawl, thereby cable is fixed.But when the water joint back-out, each clamp jaw of interior pawl unclamps and no longer compresses cable, owing to have certain clearance between nut inwall and the interior pawl outer wall, interior pawl can freely get loose, and does not have locking functions simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of nut that prevents mold release function that has is provided.
In order to overcome the defective that exists in the background technique, the technological scheme that its technical problem that solves the utility model adopts is: a kind of jam nut, the tubular body that comprises a hollow, the inwall on described body top is circular arc to outer lug, form backstopping assembly, the inwall of described body is provided with internal thread, and described backstopping assembly is provided with at least one projection.
In preferred embodiment of the utility model, described projection axially radially distributes to circumference from the center of circle along described body.
In preferred embodiment of the utility model, the quantity of described projection is 2 to 6, and evenly distributes.
In preferred embodiment of the utility model, described projection and described backstopping assembly are one-body molded.
The utility model has solved the defective that exists in the background technique, the nut that the utility model disclosed, the inwall of the tubular body of its hollow is circular arc to outer lug, form backstopping assembly, and described backstopping assembly is provided with at least one projection, and described projection axially radially distributes to circumference from the center of circle along described body.When interior pawl is inserted nut, under the promotion of water joint and under the compressing of nut circular arc backstopping assembly, the clamp jaw of interior pawl is clamped cable, is fixed; When water joint is screwed out, under the clamping action of backstopping assembly, interior pawl can not get loose easily, and this nut is simple in structure, with low cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 is the assembly structure schematic representation of preferred embodiment of the present utility model.
Wherein: 1, nut; 11, body; 12, backstopping assembly; 13, internal thread; 14, projection; 2, interior pawl; 3, plug; 4, water joint; 5, cable.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, the utility model has disclosed a kind of jam nut, comprises the tubular body 11 of a hollow, the inwall on body 11 tops is circular arc to outer lug, form backstopping assembly 12, be used for backstop interior pawl 2 as shown in Figure 2, pawl 2 exposes the port of nut 1 in avoiding.The inwall of body 11 is provided with internal thread 13, is used for and is provided with closely cooperating of externally threaded water joint 4.
Its backstopping assembly 12 of traditional nut is level and smooth circular arc, and when water joint 4 back-outs, owing to have certain clearance between the inwall of nut 1 and the interior pawl 2, interior pawl 2 will break away from nut 1 easily.In the utility model preferred embodiment, backstopping assembly 12 is provided with at least one projection 14, and projection 14 axially radially distributing to circumference from the center of circle along body 11.
Preferably, the quantity of projection 14 is even number, and evenly distributes.Reach preferable clamping effect between the clamp jaw for pawl 2 in making, consider manufacture cost simultaneously, the quantity of projection 14 is 2 to 6.
Preferably, projection 14 and backstopping assembly 12 are one-body molded.
During use, cable 5 is passed nut 1, interior pawl 2, plug 3 and water joint 4 successively, then by the internal thread 13 of nut 1 and the outside thread of water joint 4, nut 1 is connected with water joint 4, under the compressing of the circular arc backstopping assembly 12 of the promotion of water joint 4 and nut 1, interior pawl 2 cable 5 is clamped, the outside thread by water joint 4 the other ends is connected with fixed block again, reaches cable 5 and the fixing effect of fixed block.
The utility model has solved the defective that exists in the background technique, the nut that the utility model disclosed, the inwall of the tubular body of its hollow is circular arc to outer lug, form backstopping assembly, and described backstopping assembly is provided with at least one projection, and described projection axially radially distributes to circumference from the center of circle along described body.When interior pawl is inserted nut, under the promotion of water joint and under the compressing of nut circular arc backstopping assembly, the clamp jaw of interior pawl is clamped cable, is fixed; When water joint is screwed out, under the clamping action of backstopping assembly, interior pawl can not get loose easily, and this nut is simple in structure, with low cost.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
