The utility model discloses only need through inflating or exit in order realizing the sheathed tube inflation or to return and contract, and then through the inflation or return the sleeve pipe that contracts and realize the fastening installation on the wall body or dismantle that need not rotate the screw rod, labour saving and time saving practices thrift installation cost, and not fragile screw, screw repeatedly usable.
Description
Technical field
This utility model relates to hardware products technical field, particularly to the fastening screw of a kind of easy disassembly.
Background technology
Install in the fastening in the localities such as body of wall, floor though screw of the prior art can realize installed part, but
Be when rotation screw relatively time-consuming arduously, be difficult to install, increase installation cost.When tearing part open, spiral shell
Silk is the most quick detachable, and is easily damaged, and causes reusing.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of cost relatively low and repeatable
The fastening screw of the easy disassembly utilized.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is by the following technical programs
Realize: a kind of easy-to-dismount jam nut, including screw rod and sleeve pipe, described screw rod is provided with external screw thread, institute
Stating sleeve pipe and have female thread, this sleeve pipe is by the externally threaded cooperation suit on the female thread on sleeve pipe and screw rod
On described screw rod, described screw rod is also set with nut and pad, the tube wall of described sleeve pipe is provided with inner chamber,
The upside of the tube wall of described sleeve pipe is provided with an air-filled pore communicated with the inner chamber of tube wall, equipped with one on this air-filled pore
Vent plug.
Further, the sidewall of described nut is provided with screwed hole, is installed by screw thread in the screwed hole of nut
One is had to hold out against screw.
Further, the hole wall of described air-filled pore is embedded with sealing ring.
Further, described vent plug is T-shaped, and described air-filled pore is also for the T-shaped structure coordinated with described vent plug.
The beneficial effects of the utility model are: be set with sleeve pipe on the screw rod in this utility model, this sleeve pipe
Tube wall is provided with inner chamber, outside tube wall, is provided with the air-filled pore communicated with inner chamber, thus by this air-filled pore to set
The inner chamber inflation of pipe, the gas being filled with makes casing expandable, and the sleeve pipe after expansion is so that screw rod is fastened
On body of wall, installed part is installed on screw rod, and fastening nut, it is achieved installed part and the installation of body of wall.?
During dismounting, only need to be released by gas, sleeve pipe bounces back, it is possible to take out this screw.This utility model only need to lead to
Gas overcharging or venting are to realize expansion or the retraction of sleeve pipe, and then are realized at wall by the sleeve pipe expanded or bounce back
Fastening installation or removal on body, need not rotate screw rod, time saving and energy saving, save installation cost, and not rapid wear
Bad screw, screw is reusable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged diagram of part A in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that this utility model
Advantage and feature can be easier to be readily appreciated by one skilled in the art, thus to protection domain of the present utility model
Make apparent clear and definite defining.
As depicted in figs. 1 and 2, the fastening screw of a kind of easy disassembly, including screw rod 1 and sleeve pipe 2, described
Screw rod 1 is provided with external screw thread, and described sleeve pipe 2 has female thread, and this sleeve pipe 2 is by the interior spiral shell on sleeve pipe 2
Externally threaded engagement sleeves on stricture of vagina and screw rod 1 is loaded on described screw rod 1, and described screw rod 1 is also set with spiral shell
Mother 3 and pad 4, be provided with inner chamber 21 in the tube wall of described sleeve pipe 2, the upside of the tube wall of described sleeve pipe 2 sets
There is an air-filled pore 22 communicated with the inner chamber 21 of tube wall, equipped with a vent plug 5 on this air-filled pore 22.
Further, the sidewall of described nut 3 is provided with screwed hole 31, passes through in the screwed hole 31 of nut 3
Screw thread is provided with one and holds out against screw 6.
Furtherly, the hole wall of described air-filled pore 22 is embedded with sealing ring 7, strengthens gas tightness.
Furtherly, described vent plug 5 is T-shaped, and described air-filled pore 22 is also the T coordinated with described vent plug 5
Shape structure.
During use, the screw rod 1 equipped with sleeve pipe 2 in this jam nut is inserted the hole held successfully on body of wall, to
Air-filled pore 22 on sleeve pipe 2 is inflated, and the gas being filled with makes sleeve pipe 2 expand, and the sleeve pipe 2 after expansion compresses
On the hole of body of wall, so that screw rod 1 is fastened onto on body of wall.After installing screw rod 1, by vent plug 5
Fill in the air-filled pore 22 of sleeve pipe 2, prevent gas from running out of.Then, installed part is installed on screw rod 1, and
Fastening nut 3, it is achieved installed part and the installation of body of wall.The sidewall of nut 3 is screwed on and holds out against screw 6, from
And it is possible to prevent nut 3 to loosen under the effect that holds out against holding out against screw 6.During dismounting, vent plug 5 can be opened,
Being released by gas in sleeve pipe 2, sleeve pipe 2 bounces back, thus can be taken out by whole screw dismounting.Disassemble
Screw reusable.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model,
Every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion, or directly
Connect or be indirectly used in other relevant technical fields, be the most in like manner included in patent protection model of the present utility model
In enclosing.
