Further, the hanging hole is the preset clearance between the deep floor, end plate.
Further, the deep floor has multipair, all deep floor equidistantly distributeds.
Compared with prior art, the advantages of the utility model and beneficial effect is:
The utility model Screw arbor with nut at both-ends built-in fitting can not only be cooperated by sleeve and Screw arbor with nut at both-ends suit, but also disassembled
It is taken out from wall breakage can not occur after template rapidly,, specifically, the disassembly work with drag hook or pulling claw can be used
Drag hook or pulling claw are linked into the hanging hole between shell, first sleeve by tool, can easily pull out built-in fitting, due to avoiding sled
Rod, screwdriver etc. have the use of destructive tool, to avoid the damage to built-in fitting while facilitating built-in fitting to take out
It ruins.In addition, avoiding it from being deformed by concrete extrusion to reinforce the structural strength of built-in fitting, also it is equipped between shell, sleeve
At least a pair of of deep floor, in order to guarantee the stability of structure, each pair of deep floor is symmetrical with respect to first sleeve, and is
Taking-up also designed enclosures convenient for built-in fitting are truncated cone-shaped structure.
After the detailed description of the utility model embodiment is read in conjunction with the figure, other features and advantages of the utility model
It will become clearer.

Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
In order to solve the problems, such as that existing Screw arbor with nut at both-ends built-in fitting is not easily taken out after disassembling template, such as Fig. 1 to Fig. 5 institute
Show, include shell, first sleeve and end plate the utility model proposes a kind of improved Screw arbor with nut at both-ends built-in fitting,
In, shell is in truncated cone-shaped and is located on the outside of sleeve, and end plate is used for gap between the small end and sleeve of closure, specifically,
End plate is in circular ring shape, and extends radially to first sleeve by the small end of shell, particularly, is opened up between shell, first sleeve
Convenience and dismantling device mount the hanging hole of cooperation, and after disassembling template, the extension of built-in fitting can be linked into using dismantling device
It is pulled out from wall in hole.
In order to improve the structural strength of built-in fitting, the utility model built-in fitting further includes being extended radially to by the inner wall of shell
The deep floor of first sleeve, in order to ensure the stability and aesthetics of structure, deep floor can be arranged in pairs, extremely such as Fig. 1
Shown in Fig. 5, specific 2 pairs of the setting into example IV in embodiment one, each pair of deep floor symmetrically divides with respect to first sleeve
Cloth, and equidistantly distributed between 4 deep floors.
For the position that opens up of hanging hole, the utility model uses a variety of feasible programs, such as:
In example 1, as shown in Figure 1, opening up hanging hole 11 on 1 pair of deep floor 10, between adjacent deep floor 10
Existing forceps for hook taking or one can be used in the resigning mouthful for foring evacuation dismantling device, dismantling device being made to be able to protrude into, extracting tool
Bending is held to form the steel bar of hook.
In example 2, as shown in Fig. 2, the use in order to avoid dismantling device is also led on the basis of example 1
Cross hanging hole 11 and connect a pair of of deep floor 10 using drawstring 12, during casting concrete, drawstring 12 filled in shell,
Between first sleeve, after disassembling template, drawstring 12, which is extracted, and pull to take out built-in fitting from wall.
In order to avoid drawstring 12 droops and is clamped to drawstring 12 in installation template, the present embodiment is in 1 deep floor 10
On process winding fixed pulling rope 12 coupler body 13 can also process clamping on deep floor 10 in another embodiment
Drawstring 12 is taken out out of coupler body 13 or card slot after disassembling template and pulls built-in fitting by the card slot of drawstring 12.
In the third embodiment, as shown in Figure 3, Figure 4, it in order to enable the drag hook of dismantling device is easier to be linked into hook, avoids tearing open
Holding tool protrudes between shell, first sleeve 20, and built-in fitting further includes telescopically be set in 20 outside of first sleeve second
Sleeve 30, and hanging hole 31 has been opened up in second sleeve 30, in order to realize symmetrical pull, in the present embodiment specifically in second sleeve
The hanging hole 31 of two Relative distributions has been opened up on 30.In casting concrete, second sleeve 30 is retracted to shell, first sleeve 20
Between, after disassembling template, second sleeve 30 is pulled out with respect to first sleeve 20 first, then using the dismounting work with drag hook
Tool disassembly built-in fitting, or two hanging holes 31 are passed through using the strut of linear type, and by pulling strut to take built-in fitting from wall
Out.
Obviously, it needs to be formed with disconnecting prevention structure between second sleeve 30 and first sleeve 20, specifically refers to existing telescoping cylinder
Structure has extended radially outward the first stop collar 21 in the outer end (for the end of adjacent housings big end) of first sleeve 20,
The inner end of two sleeves 30 extends radially inward the second stop collar 32, utilizes stopping between the first stop collar 21 and the second stop collar 32
Gear cooperates that second sleeve 30 is prevented to be detached from first sleeve 20.
In example IV, as shown in figure 5, preset clearance specifically is formed between 1 pair of deep floor of design and end plate 40, and
Above-mentioned hanging hole is formed using preset clearance, and the resigning mouthful of evacuation dismantling device is formd between adjacent deep floor.
The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of variation.But it is all without departing from the content of the technical scheme of the utility model, the technology according to the utility model is real
Matter any simple modification, equivalent variations and remodeling to the above embodiments, still fall within the guarantor of technical solutions of the utility model
Protect range.
