Definitions
- the invention relates to a hand spray gun for a High-pressure cleaning device with a housing in which a connector of a high pressure line for connection insertable with a connection inside the housing is, and with a laterally insertable into the housing U-shaped securing element, which in one in the housing inserted with its fixing position two legs side recesses of the connector engages behind and thereby the connector in the housing secures against pulling out, and which one the housing is pulled out to the connector to Pull out to release it from the case.
- Such hand spray guns are made, for example EP 0 885 661 A2 or DE 27 20 241 A1.
- the connector can be freely rotated in the connector but axially fixed, this determination can easily be removed by that the securing element laterally, that is transverse to Longitudinal direction of the connector, pulled out of the housing becomes.
- the legs of the U-shaped Securing element normally in side recesses engage through a circumferential groove on the connector be formed.
- the locking members can be designed very differently be, for example, chain-like or ribbon-like Tendons should be on the one hand with the legs and on the other hand are connected to the housing and limit the extension movement, in a preferred one
- the Locking members are stops that stop on the housing stop as soon as the safety element is out a release position releasing the connector is pulled further out of the housing.
- the stops transversely to the direction of displacement of the securing element in the housing resilient can be inserted. This makes it possible To insert the securing element into the housing, for example for assembly purposes, the stops inserted resiliently and allow gliding past on the stops in the housing, after that it is however, the securing element is no longer possible pull out of the housing.
- the stops on Securing element are formed by lateral projections on the outside of the legs, in particular can the side projections at the free end of the Leg be arranged.
- legs are resilient against each other are pushable, so that the stops can be pressed resiliently against one another and thus at a distance can be reduced.
- the stops on the housing can be formed by the one insertion opening for the securing element surrounding wall of the housing.
- stops on the housing are formed by Lateral protrusions in a sliding opening for the securing element connecting receiving shaft for the securing element.
- the distances of the protrusions correspond to the width of the securing element that the Has securing element at a distance from its stops. This will secure the element between them Projections led as soon as the stops on the free End of the legs after inserting the securing element have slipped past these projections.
- locking projections on the housing are arranged, the stops of the securing element reach behind in the fixing position. This results in the securing element being fixed in the fixing position, however, this definition is not permanently, but against a certain resistance can the fuse element out again the fixing position can be pulled out.
- the legs of the securing element in the fixing position dive into wells that are an approximation limit the free ends of the legs. Thereby will also insert the stops when locking the fixing position difficult, so that the Set the retention force with which the securing element is held in the fixing position.
- the handheld spray gun 1 shown in FIG. 1 comprises a housing 2, which is formed from two half-shells 3, 4 which is built up essentially in mirror image and are connected to each other in a suitable manner can, for example by riveting, welding, Screw connection, etc.
- housing 2 penetrating line 5 Inside the housing 2 is the housing 2 penetrating line 5, in which a closing valve can be turned on, which protrudes from the housing 2 and can be operated from the outside.
- the line 5 is on the one hand with a to a delivery point leading jet pipe 7 in connection and another with a handgun 1 with Pressure outlet of a not shown in the drawing Connecting the pump of a high-pressure cleaning device High-pressure line 8, which ends in a connector 9.
- This connector 9 is in a sleeve-shaped connection 10 of the line 5 inserted in the longitudinal direction, whereby by suitable, not shown in the drawing Sealant a seal of the connector 9 takes place with respect to the connection 10.
- Connector 9 is on the housing 2 at one
- An insertion opening 11 is provided on the side which is followed by an insertion shaft 12, this insertion opening 11 and the subsequent insertion shaft 12 take a U-shaped securing element 13 with two parallel legs 14, 15 and one connecting them Web 16, which is in the insertion shaft 12 can be inserted that the two legs 14th and 15 the connector 9 between them in immerse a circumferential groove 17 of the connector 9 and thereby facing the connector 9 in the axial direction fix the housing 2.
- the U-shaped securing element 13 is made of an elastic Plastic trained and carries on the free Ends of the legs 14, 15 protruding outwards 18, 19 by elastic bending the legs 14, 15 can be approximated.
- the locking projections 23 and 24 are opposite in that Interior of the insertion shaft 12 projecting wall elements 26, between itself and the wall of the insertion shaft 12 Insertion channels 27, 28 for the free ends of the legs 14 and 15 and the projections 18 and 19 train.
- the circumferential groove 17 is exactly in the area of the insertion shaft 12 of the housing 2, and by inserting the securing element 13 into the Insertion shaft 12 can be the connector 9 in the axial Direction in this position.
- the securing element 13 in the insertion shaft 12 slide the projections 18 and 19 on the Sliding surfaces 21 of the projections, and thereby the legs 14 and 15 with the arranged thereon Projections 18 and 19 elastically moved towards each other, so that the protrusions 18 and 19 on the protrusions 20th can slide past.
- the securing element can this fixing position can be pulled out into a Release position in which the legs 14, 15 from the Circumferential groove 17 are pulled out, but in which the Projections 18 and 19 of the legs 14 and 15 on the steps 22 of the projections 20 strike and thus a complete Pulling out the securing element 13 prevent the insertion shaft 12.
- the securing element 13 is thereby held captive on the housing and can be anywhere between the fixing position and the release position be pushed back and forth.
