Definitions
- the invention relates to a device for connecting segments of a transport line for liquids, which has a base part provided with at least one recess and a counter element which is equipped with at least one operating element which is connected to a holder element which can be inserted into the recess of the base part.
- Such devices for connection are used in the form of couplings in a variety of applications.
- a typical area of application is in the filling of storage tanks in the area of petrol stations to a connecting piece on the storage tank, the connecting piece forming the base part, to couple a counter element which is placed as an end piece on a filling hose.
- the filling hose is on opposite end of its extent connected to the transport tank of the tank truck.
- lever arm couplings To support manual operability, versions as lever arm couplings are known, the construction of which is defined in the German standard DIN 28 28. According to a special training, so-called camlock couplings are also used.
- the known coupling elements have various disadvantages.
- Relatively small levers are often used as control elements for carrying out a mechanical connection between the base part and the counter element, two levers usually being arranged opposite one another.
- mechanical fixation is only provided at two points. It is neither possible to re-tighten to avoid leaks, nor to lock it in place, which would prevent the coupling connection from being unintentionally released.
- the handling when carrying out a bracing of the coupling elements and a loosening of the bracing is cumbersome and can only be carried out with relatively great difficulty by operators who are wearing gloves.
- the object of the present invention is therefore to construct a device of the type mentioned in the introduction in such a way that an improved connection quality is provided and that handling is facilitated.
- the recess of the base part extends as a circumferential groove along an outer circumference of the base part and that the mounting element runs along the depression after the base part and the counter element have been joined together and is displaceable into the depression transversely to a center line of the counter element when the control element is actuated.
- the recess of the base part as a circumferential circumferential groove, it is possible for the mounting element to transmit clamping forces at a plurality of contact points for fixing the coupling parts relative to one another into the base part.
- the displaceability of the mounting element transversely to the center line and thus also transversely to the intended flow direction of the liquids to be passed on supports a simple structural design and a robust construction.
- control element is designed as a lever.
- the operating element is connected to a clamping ring which engages with an internal thread in an external thread of the counter element.
- Avoiding leaks is supported in that a seal is arranged in the direction of an intended tension between the base part and the counter element.
- a simple mechanical construction for positioning the mounting element is provided in that the clamping ring is the mounting element has acting and oblique to the center line positioning flank.
- control element be arranged pivotable relative to an axis of rotation.
- An unintentional loosening of the line coupling can be avoided by arranging the control element with a locking tooth so that it can be inserted and locked in a toothing.
- an intended range of movement for the clamping ring be limited by stops.
- the base part and the counter element are arranged at least in regions, so that they can be plugged together coaxially.
- a typical area of application is developed in that at least the base part or the counter element can be connected to a storage tank for liquid fuels. It is also contemplated that at least the base part or the counter element can be connected with a filling hose.
- At least the base part or the counter-element be provided with an internal thread in the region of their ends facing away from one another for holding a connecting piece provided with an external thread.
- An increase in operational safety can be achieved in that an intended locking device is provided with a spring preload in the direction of a locking position.
- a simple manufacturing technology with high functional reliability is supported in that the mounting element is formed from a plurality of balls.
- the balls are positioned by a bushing which has recesses which, at least in some areas, have a diameter which is smaller than the ball diameter.
- a compact structure is supported in that the bushing extends essentially cylindrical and concentrically relative to the center line.
- SPARE BLADE (RULE 26) 1 is a partial longitudinal section through an assembled base part with counter element
- FIG. 2 shows the device according to FIG. 1 after the base part and counter element have been braced relative to one another and after the operating element has been flipped over to take a locking position
- Fig. 3 shows a modified embodiment of the device in which balls are used to carry out a positive locking, which are positioned and secured by a socket with recesses
- Fig. 4 is an enlarged view of the detail IV in Fig. 3 with a plurality of illustrated positions of the ball.
- a coupling element for connecting segments of a transport line consists of a base part (1) and a counter element (2).
- the counter element (2) is equipped with an operating element (3) which positions a mounting element (4).
- the mounting element (4) can be inserted into an indentation (5) of the base part (1) by means of an assigned positioning movement of the control element (3).
- the depression (5) extends as a circumferential groove along an outer circumference (6) of the base part (1).
- the Counter element (2) has a receptacle (7) for the holding element (4), in which the holding element (4) is arranged before the position is shifted into the recess (5).
- the counter element (2) has an external thread (8) into which an internal thread (9) of a clamping ring (19) engages.
- the interlocking threads (8, 9) convert a rotational movement of the tension ring (19) relative to a center line (10) into a translation movement in the direction of the longitudinal extent of the center line (10).
- the clamping ring (19) in the area of the receptacle (7) has an obliquely arranged positioning flank (11) which, when the clamping ring (19) translates in the direction of the longitudinal extension of the center line (10), transversely positions the holding element (4) transversely to Center line (10) caused. During a tensioning movement, this causes a reduction in the distance between the holding element (4) and the center line (10), which leads to a transfer of the holding element (4) into the recess (5) of the base part (1).
- a seal (13) is arranged in the area of an end boundary (12) of the base part (1) and can be designed, for example, as a sealing ring.
- the seal (13) is clamped between the end delimitation (12) of the base part (1) and a pressure surface (14) of the counter element (2).
- the bracing is caused by the translational movement of the counter element (2) relative to the base part (1), which is caused by the rotary movement and the translation movement of the clamping ring (19) is conditioned.
- the base part (1) and the counter element (2) are provided with internal threads (15, 16) in the region of their ends facing away from one another, into which the line segments to be connected can be inserted.
- the line segments are expediently provided with external threads.
- Flat seals (17, 18) are arranged in the area of the internal thread (15, 16), which seal after the respective line segments have been screwed in, relative to the coupling parts.
- the counter element (2) is provided in the region of the clamping ring (19) with a pivotable control element (3) .
- the pivoting takes place relative to an axis of rotation (20) which extends transversely to the longitudinal extent of the center line (10).
- a locking tooth (21) of the lever-like control element (3) engages in a toothing (22) of the counter element (3) which runs along an outer circumference of the Ge - Geniata ⁇ (2) is arranged.
- a 1 rotational movement of the clamping ring (19) relative to the counter element (2) or to the base part (1) is not possible. This provides a lock.
- FIG. 2 shows the base part (1), the counter element (2) and the clamping ring (19) in a positioning position a tensioning of the counter element (2) relative to the base part (1).
- the mounting element (4) is partially inserted into the recess (5) of the base part (1) and leads to a positive connection. It can also be seen that the locking tooth (21) engages in the toothing (22).
- the counter element (2) When carrying out a coupling process, the counter element (2) is first pushed onto the base part (1). Then, in the positioning of the control element (3) shown in FIG. 1, the clamping ring (19) rotates relative to the counter element (2) and the base part (1). The resulting translational movement leads to a displacement of the holding element (4) in the area of the recess (5) of the base part (1). With increasing rotation of the control element (3) and the tension ring (19) connected to it, the base part (1) is braced relative to the counter element (2) in the area of the seal (13). The rotary movement can thus be continued until a sufficient sealing effect is achieved. Basically, however, it is provided that stops are provided for the rotary movement of the clamping ring (19), so that a maximum range is specified for carrying out the rotary movement.
- the control element (3) is pivoted with its locking tooth (21) into the toothing (22) of the counter element (2).
- a sufficiently stable circumferential spiral spring can be used as the material for the holding element (4).
- a sufficiently deformable and at the same time pressure-stable sealing ring or a plurality of balls or other types of pressure elements lined up along a connecting band can be used.
- eccentrics instead of the execution of the tensioning process explained in the figures by means of a rotatable tensioning ring (19), which generate the required tensioning forces during positioning with the aid of tensioning levers.
- the holding element (4) can, for example, return from the receptacle (7) into the recess (5) due to an inherent elasticity.
- FIG. 1 and FIG. 2 merely show, by way of example, a possible implementation of the coupling principle explained. Principle A large number of other constructive implementation options are conceivable.
- FIG. 3 shows the use of holding elements (4) which are designed as a ball.
- a bushing (23) is provided for positioning and holding the balls, which has recesses (24), the diameter of which are approximately smaller than corresponds to a diameter of the balls. This makes it possible to pass the balls through the recesses (24) in some areas, but a complete passage of the balls through the recesses (24) is prevented.
- the bushing (23) extends essentially cylindrically along an outer circumference of the base part (1) and delimits the receptacle (7) in the area of the clamping rings (19) from the recess (5) in the base part (1). from.
- FIG. 4 shows how a plurality of different positions is taken up by the ball during a relative movement of the clamping ring (19) relative to the base part (1) by sliding along the positioning flank (11) and 'like the ball in a corresponding relative movement between the clamping ring (19) and the base part (1) is pressed into the recess (5) of the base part (1) in order to carry out a force-fitting and form-fitting connection.
