Detailed Description
The following description of the technical solutions in the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. The technical means used in the examples are conventional means well known to those skilled in the art unless otherwise indicated.
In the description of the utility model, it should be understood that the terms "longitudinal," "transverse," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate describing the utility model, and do not indicate or imply that the devices or elements being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the utility model.
In this embodiment, a bolt guard is provided, as shown in fig. 1. The protective cover comprises a protective cover body 1 and a locking structure, wherein the locking structure is arranged in the protective cover body 1 and comprises a locking plate 3, and the locking plate 3 can be far away from/close to the inner side wall of the protective cover body; during operation, the locking plate 3 is abutted with the nut 5 to fix the protective cover body 1 and the bolt.
An elastic component is arranged on the inner side wall of the protective cover body 1, and the other end of the elastic component is connected with the locking plate 3. The elastic component can be a spring 4, an elastic block or other elastic components made of elastic materials. The elastic component is the spring 4, and during the operating condition, the spring 4 is in the compression state. In order to prevent the spring 4 from rusting, a telescopic sleeve can be sleeved on the periphery of the spring 4, and the telescopic sleeve can be telescopic according to the length of the spring. The elastic component is the elastic block, and during the operating condition, the elastic block is in compression.
The connection structure between the locking plate 3 and the protective cover body 1 is as follows: the locking plate 3 is connected with the inner side wall of the protective cover body 1 through the locking plate fixing cover 2. Specifically, the locking plate fixed cover 2 is fixedly arranged on the inner side wall of the protective cover main body 1, the upper end of the locking plate 3 is connected with the locking plate fixed cover 2, and the lower end of the locking plate 3 is a free end. The lower extreme of locking plate 3 is provided with the transition portion towards protection casing body 1 inboard slope, and when protection casing body 1 pushed down, this transition portion contacted with nut 5 at first, and protection casing body 1 continues to push down, and the elastomeric element compresses, and the upper portion offsets with nut 5 in the locking plate 3.
Specifically, the locking plate fixing cover 2 is a hollow rectangular box with screw holes, and the locking plate fixing box 2 is fixed in the protective cover body 1 by using screws instead of welding, so that the locking plate fixing cover is convenient to repair and replace in time after damage or aging; the spring 4 is replaced by an elastic block, which is one of the cores of the protection device, so that the maintenance period can be effectively reduced, the spring 4 can be aged and lose elastic stress although the stretching degree is good, the elastic block is not used, and the maintenance cost can be reduced by using the elastic block.
Further, the shape of the protective cover body 1 corresponds to the bolt. Specifically, the size of the inner periphery of the inner cavity of the protective cover body 1 is larger than the size of the outer periphery of the nut 5, so that the protective cover body 1 is conveniently sleeved on the outer periphery of the nut 5.
In a preferred embodiment, a plurality of groups of locking structures are arranged in the protective cover body 1; the plurality of groups of locking structures are uniformly distributed on the protective cover body 1 and are positioned on the same horizontal plane. When one group of locking structures fails, the other groups of locking structures can still work, so that the protection function of the protection device is prevented from failing.
In this embodiment, protection casing body 1 is protector's major structure mainly used protection bolt, prevents that the bolt from rust, locking plate fixed cover 2, locking plate 3 and spring 4 are this protector's core structure, wherein locking plate fixed cover 2 mainly used is fixed locking plate 3, locking plate 3 mainly used protector prevents to drop with the locking after the bolt cooperation, spring 4 mainly used locking buffering between locking plate 3 and the bolt, and after the installation is accomplished spring 4 can for locking plate 3 is strengthened to exert a pressure, prevents that locking device drops and leads to the bolt to expose by corrosion rust.
For a better understanding of the present utility model, the following is a complete description of the principles of the utility model: when the protective device is installed, the protective device is placed right above a bolt, the protective cover body 1 is slowly moved downwards after being aligned with the bolt, the lower end of the locking plate 3 is in contact with the periphery of the nut 5, the protective cover body 1 is continuously moved downwards until the lower end of the protective cover body 1 is in contact with the plane of the installation bolt, the bolt and the nut 5 are completely located in a closed area surrounded by the protective cover body 1 and the bolt installation surface, at the moment, the elastic component is in a compressed state, the locking plate 3 is in contact with the periphery of the nut 5, and under the action of the elastic force of the elastic component, the locking and the fixing between the protective cover body 1 and the nut 5 are realized, so that the protective cover body 1 is prevented from falling off from the bolt. The device directly cup joints protection casing body 1 at nut 5 periphery when the installation, need not to use other bolts to cooperate the installation, can effectively practice thrift installation time, installation cost.
While the embodiments of the present utility model have been described in detail, the present utility model is not limited to the embodiments described above, and various equivalent modifications and substitutions can be made by those skilled in the art without departing from the spirit of the present utility model, and these are intended to be included in the scope of the present utility model as defined in the appended claims.
