Description

Nut anti-theft protective cover

Technical Field

The utility model relates to a nut protection casing technical field specifically is a nut theftproof protection casing.

Background

The nut is also called as a nut cap, and is a fixing tool, the center of the nut is provided with a hole, the inner side of the hole is provided with a thread, the nut is often shared with the screw with the same size to fix the related joint part, and the television station and various newspaper media are reported continuously at present, the guard bar of the highway in the field, the power supply iron tower, the railway facility and the like are stolen and unloaded by lawless persons, which causes huge loss to the life and property of the country and people, therefore, a plurality of nuts need to be provided with protective covers after being installed;

the existing nut anti-theft protection cover is directly sleeved on a nut, and the installation mode is not firm and the anti-theft effect is poor, so that the nut anti-theft protection cover is provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a nut theftproof protection casing to it all is direct the cover on the nut to put forward current nut theftproof protection casing in solving above-mentioned background art, and such mounting means is not firm, the poor problem of theftproof effect moreover.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a nut theftproof protection casing, includes the set casing, the inboard first spacing limit of fixedly connected with in upper end of set casing, the bottom fixedly connected with second spacing strip of set casing, the inside of set casing is provided with the cap, the first spacing strip of outside fixedly connected with of cap, the cap inboard is fixed with the spacing limit of second.

Preferably, the bottom of the fixed shell is provided with a through hole, so that the fixed shell is conveniently connected with the bolt.

Preferably, the specific number of the first limit edges, the first limit strips, the second limit edges and the second limit strips is four, so that the tightness between the shell cover and the shell is improved.

Preferably, the upper end face of the first limiting strip is attached to the lower end face of the first limiting edge, so that the shell cover is prevented from being separated.

Preferably, the lower end face of the second limiting strip is attached to the upper end face of the second limiting edge, so that a dual limiting effect is achieved.

Preferably, the fixed shell, the shell cover, the first limiting edge, the first limiting strip, the second limiting edge and the second limiting strip are made of stainless steel materials, so that the fixed shell, the shell cover, the first limiting edge, the first limiting strip, the second limiting edge and the second limiting strip are not easy to rust.

Compared with the prior art, the beneficial effects of the utility model are that: this nut theftproof protection casing makes its use of mutually supporting through being provided with first spacing limit, first spacing strip, the spacing limit of second and the spacing strip of second, can realize the dual protection to cap and casing in the protection casing, fine realization the theftproof effect of protection casing to the nut.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to which the reference is made must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a nut theftproof protection casing, including set casing 1, the bottom of set casing 1 is provided with perforation 5, be convenient for with set casing 1 and bolted connection, the inboard first spacing limit of fixedly connected with 2 of upper end of set casing 1, the spacing strip of bottom fixedly connected with second 6 of set casing 1, the inside of set casing 1 is provided with cap 3, the outside fixedly connected with first spacing strip 4 of cap 3, the inboard of cap 3 is fixed with the spacing limit of second 7, first spacing limit 2, first spacing strip 4, the spacing limit of second 7 and the spacing strip of second 6's specific quantity all is provided with four groups, the fastening nature of cap 3 with casing 1 has been improved, the up end of first spacing strip 4 pastes tightly at the lower terminal surface of first spacing limit 2, avoid cap 3 to break away from, the lower terminal surface of the spacing strip of second 6 pastes tightly the up end at the spacing limit of second 7, play dual limiting displacement, set

casing

1, 3, first spacing limit 2, first spacing strip 4, the spacing limit of second 7 and the spacing strip of second 6 are stainless steel difficult to make it rusty.

The working principle is as follows: first cup joint set casing 1 on the bolt, then put into the nut to set casing 1 in and screw up and fix set casing 1 on the bolt, then compress tightly cap 3 in set casing 1 again for the up end of first spacing 4 pastes the lower terminal surface of tightly at first spacing limit 2, and the lower terminal surface of the spacing 6 of second pastes the up end at the spacing limit 7 of second, thereby fixes spacingly to cap 3.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
