Abstract
The invention relates to a fixing device of a flexible sleeve. Sleeves (3, 18) are used for leading cables or pipes into walls (1, 24), partition walls or other structures. The fixing device is provided with three main parts, i.e. a sealing object (2), the sleeves (3, 18) used for embedding the sealing object (2) and one or more flexible parts such as film layers (4, 22, 23), wherein the sleeves (3, 8) are arranged on the inner side part of each of the film layers (4, 22, 23), and the outer side part of each of the film layers (4, 22, 23) is mounted on the walls (1, 24) or other structures. With the fixing device, the movement of the embedded cables or pipes in each direction is absorbed by the film layers (4, 22, 23), and the vibration of the cables and the pipes is also absorbed by the film layers.
Description
Technical field
The present invention relates to a kind of cover pipe fixing device that is used for introducing cable or pipe.Say so exactly and relate to a flexible fixing device that is used for wall, partition wall or other structural sleeve pipe.
Background technique
The sealing of pipe and cable is introduced in has unique layout that pipe or cable can be moved usually under the different structure.The layout of this uniqueness can be the dilatant as particular design.Because the variation of temperature or mechanical stress, pipe and cable may move.The peak load of cataclysm also may make pipe or cable be moved.
The sealing leading device should be able to be resisted the pressure of locating liquid or gas, and can prevent fires.
Summary of the invention
Though the present invention mainly is being described in conjunction with pipe, one of ordinary skill in the art understands that it is equally applicable to cable.
According to the present invention, a sealer is installed in the cavity of wall, partition wall or other structure, when pipeline or cable system moved, sealer can be with pipe or cable vertically or move radially.Fixing device comprises the parts that seal.Comprise flexible part simultaneously, it can make sealer move and do not reduce airtight quality with pipe.
According to one aspect of the present invention be, a flexible rete is established at the edge of a sleeve pipe, makes the sleeve pipe that comprises sealer when moving, and can keep its integrity.This move may be that temperature variation by the pipe of metal material causes, makes the pipe contraction or expansion.
According to another aspect of the present invention is the periphery that a sleeve pipe is located at a jaw device, and sealer can be moved radially.Jaw device comprises flexible rete.Moving may be because vibration or the mobile of pipe-line system are caused, and the variation in pressure that also may pipe-line system be subjected to causes.
Making sealer but not bearing a mobile benefit in the pipe-line system is that the pipe Path selection is kept continuously and dilatant that need not be specific.
Other purposes of the present utility model and advantage will be presented in face of one of ordinary skill in the art by the detailed description of following embodiment.
Description of drawings
The present invention will further describe by the following examples and accompanying drawing, in the accompanying drawings:
Figure 1 shows that the schematic perspective view of cover pipe fixing device of the present invention, fixing device is installed in the cavity of wall;
Fig. 2 observes the schematic perspective view of fixing device shown in Figure 1 from wall opposite side angle;
Fig. 3 is the schematic perspective view after the expansion of fixing device illustrated in figures 1 and 2;
Fig. 4 is the floor map of another fixing device of the present invention;
Fig. 5 is the generalized section along Fig. 4 hatching line A-A.
Embodiment
The pipe cross-under of holding in the cavity of wall 1, partition wall or other structure shown in Fig. 1-3 or the fixing device of leading device have 3 critical pieces: sealer 2, a sleeve pipe 3 and a flexible part 4 as shown in the figure that embeds sealer.The said fixing device can be used for the introducing of cable equally.
Employed term " radially ", " axially " and other similar statement are the angles of following the cable that embeds sealer 2 when describing here.Term " forward " and other similar statement reference be the direction that sealer 2 embeds wall 1 one sides of sleeve pipes 3, term " rear portion " and other similar statement reference be the opposite side of wall 1.Although leading device and each parts are to illustrate with cylindric or ring-type, one of ordinary skill in the art can understand that they can present other shapes.In addition, different parts can be made of one, although they show with two parts in the drawings usually.Usually different parts are made two parts and can be made simple installation, especially when pipe or cable have been in place.
The external diameter of the back end flange 13 of sleeve pipe 3 is less than the internal diameter of wall 1 corresponding cavity.Sleeve pipe 3 is fixed in rete 4, and rete 4 is fixed on the wall 1 more successively.Can absorb moving axially of sleeve pipe 3 owing to the elasticity of rete 4.Rete 4 also can absorb radially or the moving or the vibration of sleeve pipe 3 of certain angle simultaneously to a certain extent.
Fig. 4,5 illustrates another kind of pipe cross-under or introduces wall 24 or the used fixing device of partition wall.The sealer identical with sealer 2 among the diagram 1-3 embodiment embeds the inner chamber of sleeve pipe 18.For this sealer for the purpose of clear does not illustrate in the drawings.
Two retes 22,23 are installed in the opposite side of wall 24.Rete 24 is elastic member by rubber or other material that is fit to become flexible.Rete 22,23 but can be other shape ringwise in other embodiments.The rete 23 of wall 24 front sides is installed between the flange 20 and wall 24 of sleeve pipe 18.The rete 22 of wall 24 rear sides is installed between securing device 25 and the wall 24.In addition, rete 22,23 has individual recess with suitable with wall 24 at the cavity place of wall 24.Rete 22,23 abuts against each other in the cavity of wall 24, and between the ring 19 and wall 24 of sleeve pipe 18.Rete 22,23 is fixed up by fastener 21, and fastener 21 passes the hole of flange 20 correspondences of sleeve pipe 18, passes the hole of rete 22,23 correspondences, passes the hole of securing device 25 correspondences.Fastener 21 also passes the hole of wall 24 correspondences, and like this, because rete 22,23 extruding walls 24, sleeve pipe 18 just is fixed in the wall 24.
Described in as above same mode, rete 22,23 has the radial engagement place, rete can be opened in 22,23 minutes so that rete 22,23 is installed around pipe or cable at junction point.Rete also can not use the form of radial tab equally as previously mentioned.
By the elasticity of rete 22,23, sleeve pipe 18 just may radially with circumferencial direction on move.Rubber rete 22,23 can also absorb sleeve pipe 18 moving and vibration at axial and certain angle direction to a certain extent.Like this, embedded pipe or the moving of cable of sealer just absorbed by this fixing device in the sleeve pipe 18.
