Description
Technical field
The present invention relates to fixed structure and shell, more particularly to a kind of tamper locked assembly and apply the tamper locked assembly
Shell.
Background technology
In fixed structure, screw locking is a kind of common fixed structure, in order to enhance the locking effect of screw, usually
Locked using jam nut.Generally on the market common jam nut be by be coated at the screw thread of screw screw glue come
Reinforce the fixed effect of screw, the above-mentioned screw that loosens locks usually using following two modes：
Mode one：Locked using aerobic cured screw glue and screw cooperation.When not locking, screw glue itself is coated
On the screw thread of screw, in use, user directly pays to lock on product by screw.
Mode two：Locked using the cured screw glue of anoxic and screw cooperation.When not locking, screw glue is uncoated in screw thread
On；When needing locking, first the cured screw glue of anoxic is coated on the screw thread of screw, screw is then secured into product again,
After screw is locked the screw hole of product, because of the cured screw glue of anoxic and air exclusion, the cured screw glue of anoxic
Just cure in screw hole, to reach the function of screw check.
But the curing mode of the aerobic cured screw glue of mode one belongs to semifixed type, is easier to dismantle after solidification, but
It is that can sometimes be not easy to construct because frictional force is excessive during screw locks, the wind of sliding tooth is even had when serious
Danger；And the curing mode of the cured screw glue of anoxic of mode two belongs to full fixed, more difficult dismounting after solidification.

It is overflowed in 112 through-hole 1123, and penetrates into threaded portion 1121 and the mounting post 221 of tight lock part 112 by plural groove 1122
Threaded hole 222 in, further enhance the connection of locking part 110 and mounting post 221；Finally, prevent disassembling 120 the second engaging
The first mutually clamping of holding section 1112 of portion 1232 and locking part 110, to prevent disassembling 120 fixings to locking part 110, this
When, prevent that the locking head 111 of locking part 110 is completely covered by by the tamper portion 121 for disassembling 120 completely, is not destroying tamper portion 121
In the case of can not dismantle locking member 110.In the present embodiment, it dismantles for convenience, screw glue selects aerobic cured screw glue.
When dismounting, the tamper portion 121 for preventing disassembling 120 is agitated using tool, interconnecting piece 122 is broken and makes 121 quilt of tamper portion
It pries open, at this point, the locking head 111 of locking part 110 is exposed, is then socketed on locking head 111 using spanner, last rotating spanner
Locking member 110 is screwed out from mounting post 221, and then relieves the locking of upper casing 210 and lower casing 220.
The tamper locked assembly 100 provided in embodiment of the present invention and the shell 200 using the tamper locked assembly 100
It is connected to the plural through-hole 1123 of shrinkage pool 1111 equipped with the shrinkage pool 1111 that can accommodate screw glue, and in 112 outside setting of tight lock part,
When the screw glue in shrinkage pool 1111 is by preventing disassembling extruding, screw glue squeezes out from plural through-hole 1123 and penetrates into lower casing
In 220 threaded hole 222 and the threaded portion 1121 of locking part 110, locking effect is good；Prevent that disassembling 120 is equipped with tamper portion 121, it can
Judge whether upper casing 210 and lower casing 220 were disassembled by checking whether tamper portion 121 is destroyed, simple in structure, practicability
By force.
Those skilled in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And it is not used as making embodiment of above as long as within the spirit of the present invention for limitation of the invention
Appropriate change and variation all fall within the scope of protection of present invention.
