Description

Plastic trough

The invention relates to a kind of plastic trough.

The assembly method of known plastic trough is carried out with bonding method, and for example built-up member closely link to each other with the outside of the end regions of every throttling channel with its inboard, and need be coated with the last layer bonding agent between two gluing of surfaces.An effect of this bonding agent is all to fit tightly on the mating face, and another effect is connected two throttling channels, so they each other can not be mobile to some extent, can not be mobile to some extent with respect to built-up member.For end closure, flowing water mouth joint, joint, bent angle joint and similarity piece are also all assembled with the same manner.

A very big shortcoming of said method is exactly that these parts must bond together, and needs operation very carefully in order to avoid adhesion errors when bonding.Leak sticking part and may produce unnecessary leakage phenomenon, and, when carrying out bonding assembling, have very big difficulty with bonding agent at wet weather.Also have, the various bonding agents of use all contain poisonous solvent, are unsuitable for the contact of people's body running.

Therefore an important requirement to plastic channel is exactly not adopt bonding agent when assembling, therefore various structures were once proposed, the caulking piece that has rubber or similar material system on this structure, with these caulking pieces be contained on built-up member and each throttling channel raceway groove or similarly in the breach.But such packing device can't prevent axial displacement reliably, therefore also may produce end play, perhaps will adopt special-purpose assembling device or fastener to keep its installation site.

Introduced a kind of plastic channel in the manual of Danish Patent 133707, it assembles up with single part, dismountable button pin with flexiplast system is assembled together it, but in the water proofing property between the mating face joint-packing part must be housed between two mating faces in order to guarantee.But this structure is also very loaded down with trivial details when operation, and its shortcoming is need have the aperture that the dress pin is used in the assembling part on each throttling channel, and the joint-packing part is surrounded pin fully, could guarantee water-tight like this.This structure also has following shortcoming, because the joint-packing part is fixing very firm with two assembling parts, it is very difficult the joint of chute being taken apart, therefore, as bonding chute, also is difficult to repair and dismantle.

The objective of the invention is to propose a kind of chute of new construction, the part of this chute is when assembling, neither need bondingly also need not use the joint-packing part, and only be to use common rubber seal, and can guarantee can not move axially between two parts, and the structure of chute can make it easily and apace assemble and pull down.

Because successfully design, make chute and Assembly part obtain above-mentioned advantage, it is characterized in that: chute and its Assembly part have interaction and interconnected locking device, the structure of this locking device such as latch segment are positioned on the part, and said latch segment is connected with locking hole on being positioned at another part.The chute of this structure can be pulled down frequently, and this is because assembling back not have permanent part under non-disconnectable, but the composite member that assembles is still very firm, so that can not produce between these parts and move axially.Can adopt the rubber caulking piece as sealing, if be ready certainly, also can adopt the joint-packing part of other type, owing to all there be not perforate on the chute of each joint and on each Assembly part, therefore assembly after this assembling is very driving fit.Because single part can be simple and easy and apace latch segment is connected with locking hole and be installed on, therefore this chute can assemble and install and can not have problems under various weather.

If chute is designed to: have a longitudinal extension bar at this chute of place at least, at an end of every throttling channel, this vertical bar is promptly removed the material on the bar at regular intervals through following machining at least, makes remaining material form this latch segment.Then each throttling channel is manufactured as known chute, have ledge, but its lock dog can be finished by simple processing.If only a processing part is made several latch segments on one or several longitudinal extension bar, then the unprocessed part of one or several longitudinal extension bar just can play reinforcing rib to every throttling channel, therefore it is thin the wall thickness of chute can being made than general chute, and perhaps the intensity of the strength ratio known configurations chute of this chute is big.

If plastic trough of the present invention is designed to: no matter being positioned at below the outer flanging bead still is to be positioned on the rear part edge, and this chute all has a longitudinal extension bar, and this can be processed into latch segment.Then latch segment is in position best on the chute, and the reinforcing rib that makes this chute is for the strongest.For example when needs are checked or cleaned this chute, need ladder is leaned against on the chute, the workman is last when carrying out work to ladder, and the longitudinal extension bar that is positioned at below the outer flanging bead can be in case the damage of this this chute.

If plastic trough of the present invention is designed to: the knee of flanging bead outside, a ditch that is longitudinal extension is arranged in the inboard of longitudinal extension bar, the interior crooked end of bracing or strutting arrangement can be installed in this ditch.Then this chute will be fixed in the supporting arrangement in simple mode, and this device can be the common chute support at band bending position.Though this chute is contained on the chute support securely, can make the work of installing and pulling down this chute be easy to carry out.

If plastic trough of the present invention is designed to: have the locking hole corresponding to the many capable longitudinal extensions on each throttling channel on each built-up member, said hole is each positioned on the outer flanging bead and is positioned on the crimp part at part rear portion.Each the row locking aperture that then extends longitudinally is arranged in the far outside (this chute stream has rainwater) apart from chute thereby will not produces sealing problem at this place, aperture.

If plastic trough of the present invention is designed to: one or several longitudinal extension bar and lock dog all be designed to central sulcus or breach with one or several locking limit.Then this latch segment can have slightly flexible so that this latch segment design can with the locking aperture state that becomes to closely cooperate, therefore, the composite member after the assembling is bound to very firm.

If the locking limit of plastic trough of the present invention has one at least with regard to bit plane, or have at least a circle to lock the shoulder part, because locking effect, this plane maybe should circle locking shoulder part can be connected with locking hole securely, then can be according to designing this latch segment to the requirement of assembling fastness and according to the material of making chute.

It is as follows to further specify the present invention with reference to following illustrated optimum implementation:

Fig. 1 is the last phantom drawing according to chute of the present invention;

Fig. 2 is the last phantom drawing of its built-up member;

Fig. 3 is the sectional drawing of locking device;

Fig. 4 is the sectional drawing of another embodiment of locking device;

Fig. 5 is according to the locking device among Fig. 3 and Fig. 4, but from the view of the place ahead V-V direction.

Reference number 1 is represented a common curved chute among Fig. 1, but also can represent the chute of other Any shape.Shown chute has the chute support 2 that inserts in the chute, in order to see clearly Chu Qijian, chute support 2 is illustrated in the end of this throttling channel, can clearly illustrate that like this aduncate end 3 on the support 2 is that how to be installed this bead of bead 4(of chute front portion is formed to locating to extend by the chute front portion) among.

At the inboard place of the rear positions of chute, bar 5 to longitudinal extension is arranged, this bar is being positioned at chute end part, with machining process (for example cutting, method such as sawing and grinding) by certain interval material is removed from this, remaining material is become have two outward extending pin shapes to form latch segment 6.

Identical with above-mentioned shape, there is a longitudinal extension bar 5 below of flanging bead 4 outside, is processed into lock dog 6 by above-mentioned with quadrat method.

With plastics (for example polyvinyl chloride) hot moulding method or similar approach longitudinal extension bar 5 and chute itself are molded into one.

As shown in Figure 2, have one in the built-up member 7 and be placed on rubber caulking piece 8 inner or that insert.These built-up member are used to connect the adjacent chute of two joints or other Assembly part and each throttling channel are linked together, should outer flanging bead 11 have the locking hole 9 of delegation to longitudinal extension, this locking hole is corresponding to the latch segment 6 on the outer flanging bead on the chute, the rear portion of built-up member has a crimp part 10, the locking hole 9 of delegation's longitudinal extension is arranged on this crimp part, and this locking hole is used for being equipped with the latch segment that is positioned at the chute posterior medial 6 as shown in fig. 1.

Shown in Fig. 3 to Fig. 5 be latch segment 6 various embodiments for example, for example this latch segment can have central sulcus 13, this central sulcus can be on the longitudinal extension bar preformed good.That latch segment is had is flexible owing to have central sulcus, if latch segment is designed to have the locking limit, for example is designed to the point locking limit on a band plane 12 or the round locking surface of band circle locking shoulder 14, then can make the latch segment locking hole of packing into easily.

For these professional personnel, can locking hole be positioned on each throttling channel the location swap of locking hole shown in the figure and latch segment, latch segment is positioned on the built-up member.After if this design is shown among the figure, it is easy to realize.
