Abstract
The utility model relates to a nut locking device which comprises a circular nut (1) and fastening bolts (3), wherein two fastening bolts (3) are arranged on the circular nut (1) and two moveable blocks (2) are arranged in the positions of the fastening bolts (3) of the circular nut (1). The nut locking device has a simple structure, is convenient to operate and has a good anti-loosening effect.
Description
Technical field:
The utility model relates to fastenings, refers more particularly to a kind of nut lock.
Background technique:
When component are assembled together at present, usually adopt bolts and nuts to cooperate, two component are installed together, two component are in long-term using process, in order to prevent nut loosening, the elastic washer that prior art is normally installed between nut and component, elastic washer applies certain elastic force to nut and withstands nut, thereby realizes the locking processing to nut.Because elastic washer is less to the elastic force that nut applies, under the environment of strenuous vibration, loosening phenomenon still can appear in nut.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, the nut lock that anti-loosing effect is good.
The utility model is achieved in that a kind of nut lock, comprises round nut, Cock screw, it is characterized in that: be provided with two Cock screws on the described round nut, the Cock screw place of round nut is provided with two movable blocks.
The groove center line that round nut described in the utility model arranges is by the center of circle of round nut, and two limits of groove parallel, and are provided with screw thread on the described movable block, and movable block and groove adopt Spielpassung.
The utility model is simple in structure, and is easy to operate, anti-loosing effect good.
Description of drawings:
Fig. 1 is the plan view in the utility model structural representation.
Fig. 2 is the plan view in the utility model structural representation.
Among the figure 1, round nut, 2, movable block, 3, Cock screw.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to accompanying drawing, a kind of nut lock comprises round nut 1, Cock screw 3, it is characterized in that: be provided with two Cock screws 3 on the described round nut 1, Cock screw 3 places of round nut 1 are provided with two movable blocks 2.The groove center line that described round nut 1 arranges is by the center of circle of round nut 1, and two limits of groove parallel, and are provided with screw thread on the described movable block 2, and movable block 2 adopts Spielpassung with groove.During implementation, two movable blocks are snapped in two grooves of round nut first, with Cock screw movable block is pushed the screw rod from groove again.The utlity model has dual locking, anti-drop function, make the connection between component more reliable, between component in case coupling mechanism force occurs and descend, only need turn Cock screw just can, and only the self-locking movable block is got final product from the round nut release when changing.
Institute is understood that; the above is the specific embodiment of model utility only, is not limited to model utility, and is all within the spirit and principle of model utility; any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of model utility.
