Definitions

  • the invention relates to a fastening device for two housing parts, in particular fan housing parts.
  • Housing parts in particular fan housing parts, are often screwed together in the prior art. However, this is comparatively complex in terms of assembly.
  • the invention is therefore based on the object of providing a fastening device device to provide with the two housing parts, in particular fan housing parts can be easily and securely connected to one another without additional tools being required.
  • a fastening device for two housing parts in particular fan housing parts, is proposed, with at least one protruding latching hook being formed on a first housing part and at least one receptacle with a contact shoulder for the attached latching of the latching hook being formed on a second housing part.
  • Each receptacle has two guide webs that extend towards one another in a V-shape and thereby define a wedge-shaped receptacle space.
  • Each latching hook has a wedge shape corresponding to the receiving space and can be inserted into the respective receptacle along the guide webs.
  • the fastening of the latching hooks and contact shoulders represents a snap connection in the sense of a latching, the position between the latching hook and the receptacle being clearly fixed locally in the fastened state.
  • the insertion opening for inserting the locking hook into the wedge-shaped receiving space is wider due to the inclusion of V-shaped guide webs extending towards one another.
  • the wedge shape of the locking hook fits accordingly to that of the receiving space, so that the comparatively narrow free end of the locking hook, ie the narrow tip of the wedge shape, is first guided to the wide V-shaped insertion opening of the receptacle for attachment.
  • the snap-in hook thus finds the insertion opening very easily, which makes manual assembly much easier.
  • the latching hook slides along the guide webs and fills the receiving space more and more until it has reached the final fastening position with engagement on the contact shoulder.
  • An advantageous embodiment of the fastening device provides that the latching hook completely fills the receiving space in the fastened state.
  • the guide webs of the receptacle then lie flat laterally on the latching hook and contribute to a secure attachment and
  • the at least one latching hook has at its free end pointing in a fastening direction towards the receiving end an engagement element which, in the fastened state, engages over the contact shoulder.
  • the latching hook is preferably designed as a hollow body.
  • a further development of the fastening device is characterized in that the guide webs are spaced apart from an axial edge plane of the second housing part which is overlapped by the latching hook in the fastened state.
  • the receptacle is thus also at a distance from the edge plane and a free space is initially provided on the housing part with the receptacle in which the latching hooks can be prepositioned. In this state, the housing parts can still be rotated relative to one another, so that the latching hooks can be assigned to the respective receptacle.
  • the locking hooks can be guided further in the direction of the receptacle and, as soon as the guide webs are reached, can be pushed along them completely into the receptacle space of the receptacle.
  • one embodiment of the fastening device provides that the at least one locking hook has a stiffening web along its extension in the direction of its free end.
  • the stiffening bar facilitates locking and fixing on the contact shoulder. This secures the attachment even if the housing parts vibrate during operation.
  • the invention is directed in particular to fan housings with two fan housing parts.
  • the first housing part is preferably designed as a protective grille.
  • the second housing part is, for example, a fan wheel around closing ring element.
  • the fan housing is preferably characterized in that at least three latching hooks are distributed on the protective grille in the circumferential direction and are designed to protrude towards the second housing part.
  • the distances in the circumferential direction are each the same, so that each latching hook can be assigned to any receptacle.
  • the fan housing provides that the protective grille has coaxial circumferential struts and radial struts extending over the circumferential struts and the latching hooks are formed at a distance from the radial struts in the circumferential direction.
  • FIG. 1 is a perspective view of two housing parts with a fastening device
  • FIG. 2 shows the housing parts from FIG. 1 in a side view
  • FIG. 3 shows the housing parts from FIG. 1 during assembly
  • FIG. 4 shows the housing parts from FIG. 1 in the attached state.
  • FIG. 1-4 an embodiment of the fastening device of two housing parts is shown, which are designed as fan housing parts 2, 3 in the form of a protective grille and a fan ring housing.
  • Housing part 3 At the Housing part 3 are formed in one piece in the circumferential direction, three geometrically identical receptacles 6 spaced apart by 120 °, each having two guide webs 9.
  • the guide webs 9 extend towards one another in a V-shape and define the wedge-shaped receiving space 5 between them.
  • the housing part 2 designed as a protective grille comprises five coaxial circumferential struts 8 and nine radial struts 7 and is designed to be axially as well as radially open.
  • the number of circumferential struts 8 and radial struts 7 can be adjusted as required.
  • Extending in one piece from the housing part 2 are three latching hooks 4, each of which has a wedge shape corresponding to the receiving space 5.
  • a stiffening web 11 is formed which extends along the respective axial extent of the locking hook 4 in the direction of its free end.
  • the latching hooks 4 each have a hook-shaped engagement element 10 which, in the fastening position, engages in the contact shoulder 12 of the respective receptacle or engages behind it.
  • the locking hooks 4 can be inserted along the guide webs 9 into the respective receptacle 6 and the respective receiving space 5, the locking hooks 4 due to the wedge shape initially being attached to one of the guide webs 9 and then axially displaceable to the fastening position which is shown in FIG.
  • the latching hooks 4 fill the respective receiving space 5 completely in the water position and lie against the guide webs 9.
  • the guide webs 9 are opposite the axial edge plane 20 of the second housing part 3 over a predetermined length, which is essentially an axial length of the hook-shaped engagement element 10 spaced.
  • the latching hooks 4 can already be brought into an overlap with the second housing part 3, but a relative rotation Movement of the two housing parts 2, 3 allows until the locking hooks 4 white ter in the direction of the receptacles 6 are guided.
  • the solution with V-shaped receptacles 6 is also advantageous in that initially only one latching hook 4 can be attached, as shown in FIG. 3, and the two other latching hooks can then be latched afterwards. Pre-positioning can thus take place on one of the receptacles 6 before the further latching hooks 4 are locked.
  • the locking hooks 4 are formed in the embodiment shown opposite the radial struts 7 spaced in the circumferential direction, ie they extend between two adjacent radial struts 7.
  • the number of locking hooks 4 and receptacles 6 is set to three in the embodiment shown, but it can also, depending on requirements only two or more than three locking hooks 4 and 6 receptacles are used.
