Abstract
The utility model relates to a theft-proof screw joint assembly belonging to the field of a theft-proof bolt assembly and comprising a bolt. The utility model is characterized in that the bolt is provided with a gland nut, and a step hole is arranged in the gland nut; a female screw matched and connected with the bolt is processed in the small hole of the step hole, and a locking nut of which the thickness is smaller than the depth of the big hole is arranged in the big hole; a ring cavity is arranged between the locking nut and the big hole of the step hole. The utility model is provided with the locking nut and the gland nut of which the inner side is provided with the step hole on the bolt, the gland nut is used for fixing guard bars (by a holder), and the locking nut is arranged in the big hole of the step hole of the gland nut; due to the fact that the dismounting of the locking nut (non-common standard hexagonal nut) uses a special tool, the utility model has the effective theft prevention and simple structure. The utility model can be widely used for the integrated coupling of the express-highway crash-proof guard bars or can be used for fixing components of a field building structure.
Description
Technical field
The utility model belongs to the anti-theft bolt component field.
Background technique
Along with the develop rapidly of China's economic construction, various open-air Architecture Designs are more and more, the fixedly employing Bolt Connection means of fixation of a lot of open-air Architecture Designs.The connecting mode that adopts plain bolt and NBS hexagon nut to add general flat gasket combination as the fastening piece that uses on the expressway anticollision barrier fixes guardrail.Yet this kind coupling assembly just can easy to do nut is turned on be pulled down with general utility tool such as screw wrench, hexagonal socket wrench, causes protection work stolen, and the vehicle of running at high speed is not had due protective action.For solving this type of problem, people have adopted non-hex jam nut (because existing socket wrench is generally inner hexagon spanner), but because existing Bolt Connection device that can be antitheft only adopts a locking nut to fix, therefore anti-theft effect is not really reliable, particularly when guardrail is subjected to clashing into, can not play reliable and effective protective action.The model utility content
For overcoming the deficiencies in the prior art, the Bolt Connection assembly that the anti-theft effect that the utility model provides a kind of locking nut without approval to be difficult to be removed reliably can be antitheft.Its technological scheme that adopts is: design a kind of Bolt Connection assembly that can be antitheft, comprise bolt, it is characterized in that being provided with on the bolt gland nut, step hole is set in the gland nut, processing and bolt are joined in the internal thread, macropore of connection the locking nut of thickness less than big hole depth are set in the aperture of step hole, between the macropore of locking nut and step hole ring cavity are set.
Ring cavity width between locking nut of the present utility model and the gland nut macropore is 1mm-5mm.The gland nut periphery is staircase structural model.Process clamp face on the small end periphery of gland nut, the quantity of clamp face is even number.The quantity of the small end periphery clamp face of gland nut is 4,6 or 8.
The utility model is provided with the gland nut of locking nut and interior band step hole on bolt, pressured jack panel is fixing with guardrail (being held part), and in the macropore of gland nut step hole, place locking nut, under the acting in conjunction of gland nut and locking nut, guardrail tightly can be clamped.Because the dismounting of locking nut (the hexangle type nut of non-common standard) must be adopted special tool, thereby can be effectively antitheft, and simple in structure; Can be widely used in that the expressway anticollision barrier is fixedly connected or the fixing usefulness of parts of other open-air building structure.
Description of drawings
Fig. 1 is an embodiment's of the utility model a structural representation;
Fig. 2 is that the A of Fig. 1 is to structural representation.
Embodiment
As shown in the figure: gland nut 3 is set on the bolt 1, processing step hole in the gland nut 3, processing and bolt 1 are joined in the internal thread, macropore of connection the locking nut 4 of width less than big hole depth are set in the aperture of step hole, and the ring cavity that width is 1mm-5mm is set between the macropore of locking nut and step hole.Both spanner can be placed in this kind ring cavity, and the intensity of spanner when pine is unloaded locking nut can be guaranteed again.The periphery of gland nut 3 is staircase structural model.For processing clamp face on the small end periphery of gland nut with common wrench clamping gland nut, the quantity of clamp face should be even number, and quantity can be 4 or 6.
Fixedly during anticollision barrier, guardrail is clipped between bolt 1 and the pad 2, guardrail is clamped thereby gland nut 3 is tightened with common wrench.Then, locking nut is tightened again with special sleeve spanner, thus securely that guardrail is fastening.Because locking nut is placed in the macropore of gland nut, and its thickness is less than the degree of depth of macropore, so common wrench can't unload it; Because locking nut is non-hexangle type nuts such as Octagon, decagonal, thereby also can't dismantle with existing common hexagonal socket wrench.Like this, when needing the dismounting locking nut, must adopt special sleeve spanner, play antitheft effect thus.
