Description

Multi-wall high-adaptability expansion bolt

Technical Field

The utility model relates to an expansion bolts technical field, concretely relates to many wall bodies high adaptability expansion bolts.

Background

In current expansion bolts, mainly lead to expansion bolts rearmost end to take place a small amount of deformation inflation through screw thread rotation pressure to combine with the wall body and play the fixed action, and prior art mainly has following shortcoming: the adaptability is not strong, and the tail end deformation range is very limited, so that the hollow brick, the foam wall and other self walls are not firm enough, the hollow brick, the foam wall and other self walls cannot be used basically, and the fixing effect cannot be achieved. The external wall is usually only 2 cm thick, so that the traditional expansion bolt cannot be fixed at all. And secondly, the installation is inconvenient, a spanner needs to be used for applying pressure in a plurality of times of rotation, and the installation is inconvenient in a part of places with limited space.

In order to solve the problems, an expansion bolt which has strong applicability, simple and reasonable structure, simple processing and manufacturing process, lower manufacturing cost, convenient installation and disassembly and safe and reliable use is needed.

SUMMERY OF THE UTILITY MODEL

To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide a suitability is strong, and simple structure is reasonable, and processing and manufacturing process are simple, manufacturing cost is lower, and the installation is dismantled comparatively conveniently, uses safe and reliable's many wall body high adaptability expansion bolts.

In order to solve the technical problem, the utility model discloses a following technical scheme:

the utility model provides a many high adaptability expansion bolts of wall body, includes screw rod, expansion pipe and expansion pipe gasket, the expansion pipe with the expansion pipe gasket is coaxial to be cup jointed on the screw rod, the expansion pipe with screw rod threaded connection, the expansion pipe is hollow tubular structure, including expansion pipe body, expansion pipe afterbody and expansion pipe tip, expansion pipe tip is provided with the screw hole, the screw rod tip connects the cooperation soon to be in threaded hole, expansion pipe body circumference evenly distributed has set up the expansion piece, the front end of expansion piece with expansion pipe end connection department is provided with the crease, the surface of the front end of expansion piece is provided with the arch, be provided with the breach in the middle of the expansion piece breach department is provided with the crease.

Therefore, through the arrangement of the expansion sheet, the expansion sheet can be unfolded in an umbrella shape during use, so that the deformation range is expanded by more than 10 times, a good filling and fixing effect can be achieved when the expansion sheet is used for facing a foam wall body and a hollow brick, the expansion sheet is additionally provided with a deformation back overturning and attaching function, and a stable fixing effect can be achieved when the expansion sheet is used for hanging a wall.

Furthermore, the tail part of the expansion pipe is provided with a ring piece, and a notch is arranged on the ring piece. The ring piece can play a supporting role.

Further, 5 expansion pieces are arranged. The expansion sheet can better play a role in filling and fixing.

Furthermore, the expansion pipe gasket is sleeved on the screw rod and is arranged between the screw rod and the expansion pipe. The expansion pipe gasket increases the contact area, reduces the pressure and protects the expansion pipe and the screw.

Further, the expansion pipe gasket is a flat gasket. The expansion pipe gasket increases the contact area, reduces the pressure and protects the expansion pipe and the screw.

Furthermore, the expansion pipe is integrally formed by adopting a sheet metal process. The integrated forming mode is adopted, the processing and the manufacturing are easy, the batch production is suitable, and the installation is firm.

In conclusion, the device can better solve the problem that walls such as hollow bricks, foam wall surfaces and externally hung wall bodies cannot be fixed by expansion bolts, can also be used as common bolts on common wall surfaces, and has the advantages of strong applicability, simple and reasonable structure, simple processing and manufacturing process, lower manufacturing cost, convenience in mounting and dismounting, and safety and reliability in use.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

During specific implementation, as shown in fig. 1-2, a high adaptability expansion bolt of many wall bodies, including screw rod 1, expansion pipe and expansion pipe gasket 6, the expansion pipe with expansion pipe gasket 6 is coaxial cup joints on the screw rod 1, the expansion pipe with 1 threaded connection of screw rod, the expansion pipe is hollow tubular structure, including expansion pipe body 4, expansion pipe afterbody 5 and expansion pipe tip 2, expansion pipe tip 2 is provided with the screw hole, 1 tip of screw rod connects the cooperation soon in the screw hole, 4 circumference evenly distributed of expansion pipe body have set up expansion piece 3, the front end of expansion piece 3 with expansion pipe tip 2 junction is provided with the crease, the surface of the front end of expansion piece 3 is provided with the arch, be provided with the breach in the middle of the expansion piece 3 the breach department is provided with the crease. Like this, through the setting of inflation piece 3 can be umbelliform during the use and strut, makes the deformation range expand more than 10 times, can reach fine filling fixed effect when just to foam wall body and hollow brick, has increased the upset laminating after warping moreover, also can play stable fixed action when hanging the wall outward.

In this embodiment, the expansion pipe tail portion 5 is provided with a ring piece, and the ring piece is provided with a notch. The ring piece can play a supporting role.

In this embodiment, 5 expansion sheets 3 are provided. The expansion sheet can better play a role in filling and fixing.

In this embodiment, the expansion pipe gasket 6 is sleeved on the screw rod 1 and is installed between the screw rod 1 and the expansion pipe. The expansion pipe gasket increases the contact area, reduces the pressure and protects the expansion pipe and the screw.

In this embodiment, the expansion pipe gasket 6 is a flat gasket. The expansion pipe gasket increases the contact area, reduces the pressure and protects the expansion pipe and the screw.

In this embodiment, the expansion pipe is integrally formed by using a sheet metal process. The integrated forming mode is adopted, the processing and the manufacturing are easy, the batch production is suitable, and the installation is firm.

This many wall bodies high adaptability expansion bolts's theory of operation and flow:

when using many high adaptability expansion bolts of wall body, at first need be played the hole that can make this many high adaptability expansion bolts of wall body put into with the drill bit on the wall body, put into many high adaptability expansion bolts of wall body again, then use the instrument to support on the expansion pipe gasket, then the fixing screw afterbody directly pulls the screw rod outwards to the wall, because the expansion piece is softer, expansion pipe front end and screw rod threaded connection, can be umbrella tensile deformation with the expansion piece in crease department, the inflation, middle part breach department outwards bulges, in order to reach the purpose that good fixed mounting was filled, and it laminates to have increased the upset after warping, also can play stable fixed action when to hanging the wall face outward.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art; the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
