Radiating fin jointing fitting

Technical field

The present invention relates to a kind of radiating fin jointing fitting, this accessory has a shell, to radiator connecting hole and at least one heating pad pipe connecting hole one by one, and wherein the radiator connecting hole is connected with radiator, and the heating pad pipe connecting hole then is connected with caliduct.

Background technology

DE29812233U1 has announced this radiating fin jointing fitting.

This radiating fin jointing fitting is mainly used in the radiator that is suspended on the wall and is connected.It is on the flow ipe and outflow pipeline of heat transport fluid that this radiator mostly no longer directly is connected on the hot duct.Exactly, this flow ipe is connected with connection fittings with the outflow pipeline.A radiator valve also can be set, for example a thermostat controlled radiator valve in this connection fittings.

In known situation, be being connected of radiator and this connection fittings to be screwed to that the external screw thread that is provided with on the radiator tube connector realizes with locking nut.This structure has many shortcomings: one, and in order to tighten this nut, the assembler must repeatedly load onto and take off instrument (for example nut spanner); Its two, there is the danger of the lacquer of damage radiator, shell or nut in this nut spanner.If this nut is japanning not, then especially may damage the finish paint of this nut material.

Summary of the invention

The objective of the invention is to simplify the installation and removal of this radiator.

Under aforementioned radiating fin jointing fitting situation, this purpose is achieved in that the opposite at least one radiator connecting hole, be provided with a fixing hole, introduced a retaining element, this retaining element and the fixedly inserts engagement that can be fixed in the radiator by this fixing hole.

This structure has plurality of advantages.At first, being used for this accessory is fixed on whole parts on the radiator all is hidden layout.Fixedly inserts is positioned at radiator, in case of necessity, is positioned at its tube connector.This retaining element is hidden by the shell of this accessory, that is the moulding of retaining element no longer is subjected to some outward appearance predetermined restricted.Secondly, need no longer to illustrate that these connection fittings directly are fixed on the radiator, this profile to fixed geometry causes some restrictions.By in radiator, be provided with one fixedly inserts and this retaining element be connected with fixing inserts, can make these two kinds to be connected corresponding application target aspect and to reach optimization.Like this, in most cases, under the situation of considering structure and economic point of view, can select a favourable solution.Fixedly inserts can removably be connected with radiator, fuses but also can or be cast on the radiator or with additive method with the radiator welding.

Fixedly inserts preferably have one can with the external stability geometry of radiator engagement and one can with the internal fixation geometry of retaining element engagement, wherein externally and be provided with a fluid passage between the internal fixation geometry at least.Therefore, on the one hand be used for making that fixing inserts meshes with radiator and these two kinds of fixed geometry that are used for meshing this retaining element on the other hand are that profile can be taken apart.Because prevention or obstruct heat transport fluid are with a solid member, so be provided with a fluid passage between these two fixed geometry in normal condition.Can there be different shape this fluid passage; In the simplest situation one or more holes.

The best center arrangement of this retaining element is at this fixedly on the inserts.The advantage of this arrangement is, accessories case is at radiator or fixedly fixedly have certain symmetry on the inserts.This symmetry is implemented in the tight connection on the whole circumference easily.And simplified assembling, because assembling can be carried out with the location independent ground of fixedly inserts in the radiator.

Between the wall of this retaining element and a passage that opens wide towards radiator connecting hole direction, a belt slit is set preferably.Though this retaining element is by guiding this passage of radiator connecting hole into, it does not block the entire cross section of this passage, but keeps an annulus, and heat transport fluid can flow through this annulus unblockedly.

This retaining element preferably constitutes as bolt.Bolt is a kind of simple especially and long-tested part that connects.At this moment, fixedly in the inserts internal thread must be set correspondingly.Like this, need only rotate this bolt simply, can be fixed on accessory on the radiator.But because from the free end operating screw of this accessory, so the assembler need not repeatedly load onto and down tools.Even especially available electronic the turn of the screw instrument.

This retaining element has a fixedly head, and this fixing head can be hidden in shell more than 50%, is particularly advantageous.In most cases, this fixing head can be hidden in shell fully, so cannot see it from the outside, like this, the bigger free degree just arranged when selecting the influential structural detail of outward appearance.

Should be fixedly inserts preferably can be screwed into radiator, available here this retaining element is in this fixing same fixed mode in the inserts.It is quite simple making external screw thread and make internal thread on fixing inserts on radiator.Also can reach very firm connection by being screwed into screw thread.

Fixedly inserts preferably has an embedding backstop.Such embedding backstop for example can constitute by an annular flange under the situation of screw thread.When this flange is close to this fixedly during the end face in the heating installation film perforation that is screwed into of inserts, it stops this fixedly continuation rotation of inserts, thus for this fixedly inserts a definite installation site is provided.

This embedding backstop is preferably hidden by shell.Like this, installing under the situation of connection fittings, just only seeing shell.All being used for this accessory is fixed on part on the radiator all is hidden layout.

Fixedly inserts preferably has the connecting plate that radially stretches out inwards, and its inboard radially is provided with the internal fixation geometry.Like this, this fixedly a big chunk of the cross section of inserts all can flow through heat transport fluid.

Brief description

Some preferred embodiments below in conjunction with accompanying drawing illustrate the present invention.Wherein accompanying drawing is represented:

The parts explosion of first kind of structural shape of Fig. 1 radiating fin jointing fitting;

Second kind of structural shape of Fig. 2 connection fittings;

The third structural shape of Fig. 3 connection fittings.

The specific embodiment

The connection fittings 1 of a kind of radiator that is not shown specifically have a shell 2, are provided with a radiator connecting hole 3 and a heating connecting hole 4 in this shell.On this radiator connecting hole, can connect unshowned radiator, on heating connecting hole 4, then can connect a hot duct, the inflow of for example a kind of heat transport fluid (as hot water) or outflow pipeline.

Before further specifying the present invention, at first should be pointed out that for clarity sake, all having omitted potted component in the accompanying drawings, in most applications, need this class potted component to seal contact site between the adjacent component.

The retaining element that is provided with 5, one bolt 6 forms of a fixing hole on the opposite of radiator connecting hole 3 can pass this fixing hole.The screw thread of bolt 6 for clarity sake, is not shown.Bolt 6 has one fixing 7.On fixing 7, be provided with a torsional interaction face, for example an interior hexagonal in the mode of knowing.

Bolt 6 passes the passage 8 of guiding radiator connecting hole 3 into.As shown in Figure 1, even this passage has step, still always have an annulus 9 between bolt 6 and shell 2, heat transport fluid can flow through this annulus.

Fixedly inserts 10 has external screw thread 11, and its available this external screw thread is fixed on the unshowned radiator.For this reason, only needing that fixing inserts 10 is screwed into this radiator gets final product.But fixedly also available other mode of inserts 10 is connected with radiator.External screw thread 11 constitutes the fixed geometry of an outside.On an end of shell 2, this fixedly inserts have an annular flange 12, this flange works to be screwed into limiter.Fixedly inserts 10 can only be screwed into radiator to such degree, and promptly flange 12 fits to till the radiator.

Fixedly inserts 10 also has the internal thread 13 that bolt 6 is screwed into.Internal thread 13 constitutes the fixed geometry of an inside.From figure as can be seen, internal thread 13 is arranged on the connecting plate 14 that radially inwardly stretches into fixing inserts 10.Leave space 15 between connecting plate, heat transport fluid can flow into radiator from radiator connecting hole 3 by this space.Certainly, but also looping and do not have the space of internal thread 13, and the space of break-through external screw thread 11 is set, or fixedly in the inserts simple hole is set at this.

Be limited in by internal thread 13 on radially inwards the end face of connecting plate 14, though reduced the bolt 6 and the fixing field of conjugate action between the inserts 10, thus the engagement that forms thus then can and be fixed on shell 2 on the radiator bolt 6 completely reliably.

Internal thread 13 best center arrangement are on fixing inserts 10, so fixedly the position of rotation of inserts 10 in radiator is nonsensical to being screwed into of screw rod 6.But wish then that in individual cases internal thread 13 is not a center arrangement.

The shell instrument has an aperture 16, and this aperture is arranged in the scope of fixing hole 5.Aperture 16 has a diameter that is large enough to hold fixing 7, the degree of depth in aperture 16 also be large enough to hold this fixing head at least half.But as fixing 7 energy is fully hidden in shell 2, then is favourable in most cases.

On one end of the opposite of shell, be provided with a surrounding wall 17 in a similar manner, this wall has the spatial accommodation that surrounds flange 12.When shell 2 installed on the radiator and is fixed on this place with bolt 6, flange 12 or rather, was covered by wall 17 fully by shell 2.

Fig. 2 represents a kind of structural shape of modification, additionally is provided with a valve 19 this moment in shell 2.Valve 19 constitutes as thermostat valve.This valve has a valve element 20, and when this valve cut out, this valve element can be close on the valve seat 21.Other part identical with Fig. 1 is still represented with identical reference number.As can be seen from the figure, fixing 7 and flange 12 are covered by shell 2 fully.

The structural shape that Fig. 2 b presentation graphs 2a looks from the outside.From figure as can be seen, cannot see retaining element from the outside at all.When accessory 1 after installing on the radiator, fixedly the external screw thread 11 of inserts 10 just cannot see on radiator.

Fig. 3 is illustrated in the third structural shape under the situation of the same pieces with equal reference numbers.This accessory has two heating connecting holes, wherein can only find out connector 22 and adpting flange 23, and the latter is positioned at the back of shell 2.Correspondingly be provided with two radiator connecting holes 3, and introduce a bolt 6 by each connecting hole, this bolt is screwed into one fixedly in the inserts 10.In this example, fixedly inserts 10 has a plurality of axially extended holes 24, and the flow channel of heat-carrying agent is played in these holes, so internal thread 13 is locked in the circumferencial direction.
