Description
Technical field
The utility model relates to a kind of door lock, particularly relates to a kind of lock body eliminating gap between bearing pin and Fang Xin.
Background technology
Along with the development of security protection industry, various lock has been there is in door lock industry, there are electronic lock and theftproof lock etc., these locks can play good security protection effect, lock body comprises shell and is arranged on the Fang Xin on shell, Fang Xin and handle pass through pinned connection, swing handle thus by bearing pin drive Fang Xin rotate, can open and close lock body, when bearing pin coordinates with Fang Xin, because Fang Xin and bearing pin link together when lock body is installed between the two, thus there will be between bearing pin with Fang Xin and coordinate unstable phenomenon, bearing pin can rock at square in-core, thus the wearing and tearing accelerated between bearing pin and Fang Xin.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of lock body can eliminating gap between bearing pin and Fang Xin.
For achieving the above object, the utility model provides following technical scheme: a kind of lock body eliminating gap between bearing pin and Fang Xin, comprise lock body body, described lock body body comprises upper cover plate, lower cover and Fang Xin, lock body upper cover plate and lower cover are established and is equipped with installing hole, described Fang Xin passes installing hole and rotates in installing hole, the sidewall of described Fang Xin is provided with fastening devices, described fastening devices comprises fixation spring tab, the two ends of described fixation spring tab are connected with the sidewall of Fang Xin, and the middle part of described fixation spring tab is that camber is arranged.
By adopting technique scheme, when bearing pin coordinates with Fang Xin, bearing pin is when insertion Fang Xin, bearing pin presses fixation spring tab, the fixation spring tab distortion being, fixation spring tab is flexible potential energy just, thus make fixation spring tab produce active force to bearing pin, can prevent bearing pin from rocking at square in-core, the curved setting in middle part of fixation spring tab, convenient when bearing pin can be made to coordinate with fixation spring tab.
The utility model is set to further: the two ends of described fixation spring tab are arranged in bending, and described side's core sidewall is provided with the fixed groove coordinated in fixation spring tab.
By adopting technique scheme, can play the fixing effect of fixation spring tab, at fixation spring tab when the active force being subject to bearing pin, the bending part of fixation spring tab moves in fixed groove, fixation spring tab can be prevented to be separated with square core sidewall, can also be convenient when installation fixation spring tab, the main fixation spring tab that needs is connected to fixed groove.
The utility model is set to further: described fastening devices is set to two groups, and two groups of fastening devicess are arranged on adjacent two side's core sidewalls.
By adopting technique scheme, the bearing pin that can make coordinates more firm with Fang Xin.
The utility model is set to further: be provided with bearing between described installing hole and Fang Xin.
By adopting technique scheme, the friction between Fang Xin and installing hole can be reduced.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation one eliminating the lock body in gap between bearing pin and Fang Xin of the utility model;
Fig. 2 is a kind of structural representation two eliminating the lock body in gap between bearing pin and Fang Xin of the utility model;
Fig. 3 is a kind of fixation spring tab structural representation eliminating the lock body in gap between bearing pin and Fang Xin of the utility model.
In figure: 1, upper cover plate; 2, lower cover; 3, Fang Xin; 4, installing hole; 5, bearing; 6, fixation spring tab; 7, fixed groove.
Detailed description of the invention
Shown in Fig. 3, a kind of lock body eliminating gap between bearing pin and Fang Xin that present case is implemented, comprise lock body body, described lock body body comprises upper cover plate 1, lower cover 2 and square core 3, lock body upper cover plate 1 and lower cover 2 are established and is equipped with installing hole 4, between described installing hole 4 and square core 3, bearing 5 is installed, described side's core 3 passes installing hole 4 and rotates in installing hole 4, the sidewall of described side's core 3 is provided with fastening devices, described fastening devices comprises fixation spring tab 6, the two ends of described fixation spring tab 6 are connected with the sidewall of square core 3, the middle part of described fixation spring tab 6 is that camber is arranged, the two ends of described fixation spring tab 6 are arranged in bending, described side's core 3 sidewall is provided with the fixed groove 7 coordinated in fixation spring tab 6, described fastening devices is set to two groups, and two groups of fastening devicess are arranged on adjacent two side's core 3 sidewalls.
When bearing pin coordinates with square core 3, bearing pin is when insertion side's core 3, bearing pin presses fixation spring tab 6, the fixation spring tab 6 being is out of shape, fixation spring tab 6 is flexible potential energy just, thus make fixation spring tab 6 pairs of bearing pins produce active force, can prevent bearing pin from rocking in square core 3, the curved setting in middle part of fixation spring tab 6, it is convenient when bearing pin can be made to coordinate with fixation spring tab 6, the two ends of fixation spring tab 6 are arranged in bending, can play the fixing effect of fixation spring tab 6, at fixation spring tab 6 when the active force being subject to bearing pin, the bending part of fixation spring tab 6 is mobile in fixed groove 7, fixation spring tab 6 can be prevented to be separated with square core 3 sidewall, can also be convenient when installation fixation spring tab 6, the main fixation spring tab 6 that needs is connected to fixed groove 7.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
