Definitions

  • the invention relates to the fact that worm drive hose clamp, which is the sealing element on the hose-fitting connections that are to be found in the engine section especially in automotive sector, remains constantly at the same position while tightening on hoses.
  • metal sheets of different scales are attached to the inner surface of the clamp. There are many angular deviations while positioning by means of these method. Furthermore, since the metal sheet part is thin, there exist sharp edges on the areas contacting the hose and they can damage the hose. As the worm drive hose clamps are particularly used in places like engine that works in vibrations within the automotive sector, the possibility that the sharp edges damage hoses is rather high. According to a patent research, no patent application that discloses the development carried out on the plastic lid belonging to the worm drive hose clamp has been found, yet the patent application with the publication number CN101493167 (A) relates to a worm drive hose clamp and a method for making this clamp.
  • the worm drive clamp comprises a tightening band that includes edge parts arranged in a way that each of them overlaps on the peripheral way in order to create a radial inner edge section and a radial external edge section. Furthermore, it comprises a protection that is connected to the radial inner edge section. A tightening screw is used in the protection in a way that it fits on the radial external edge section. The radial inner edge section is arranged such that it projects from the protection in peripheral direction.
  • the patent application with the publication number DE102007057838 (A1 ) relates to a hose clamp that is used for tying the edge part of the hose to an edge part of a pipe, and the hose diameter in center is smaller than the clamp diameter at the side.
  • the patent application with the publication number WO 0242675 A2 relates to bracket comprising a double reciprocal projection that presses on a screw protection cover and screwed protection of the clamp. The projections can be extended into or out of the / Protection cover. A single projection is formed on each of the mutual surfaces of the screw protection cover for keeping the bracket on the screw protection. Edge covers are used along the mutual surfaces of the screw protection cover for keeping the position of the screw protection that is in the screw protection cover during the montage fixed and avoiding the slide of the clamp.
  • the main objective of the invention relates to the fact that worm drive hose clamp, which is the sealing element on the hose-fitting connections that are to be found in the engine section especially in automotive sector, remains constantly at the same position while tightening on • hoses.
  • Another main objective according to the invention is time saving in the assembly line by positioning the clamp on the hose at the manufacturer of the hose and providing that the clamp is tightened at the right position.
  • the clamp is seated on the housing part without any gap by taking the vibrating environment of the engine and generally the automobile into account.
  • the flexible middle lug that is positioned at the converse direction of the clamp screw head and provides better seating of the part on the housing part, and the structure comprising of three lugs, two of which are side lugs, are the features that make the design superior.
  • Contact of the plastic cover to the housing parts along with the lugs in the front over five points and the clamp being the same form as the housing form provide that the plastic part is not detached from the housing part even under external forces or vibration effect. Thanks to the existence of rounded lines at each side and corner, and as the cutting surfaces of the metal parts are in the area that are not contacting the hose, the damage on the hose and the mounting person is avoided.
  • a worm drive hose clamp of the type that comprises a clamp band providing the tightening of the hose, a screw that provides the decreasing diameter of the clamp band by pulling band from the threads on the clamp band when turned, a housing part that acts as the bearing during the transfer of the rotating force to the clamp band by the screw and carries the plastic cover and a plastic cover that provides, during the tightening, the tightening of the clamp constantly at the same position by preventing the rotating of the clamp on the hose, is developed, wherein; the rests placed on the plastic cover provide the tightening of the clamp- on the hose always at the same position by resting against the projections on the hose, and it comprises a flexible rear mid lug that provides the seating of the plastic cover on the housing part through its flexible structure without any gap in the inner area of it where the rests of the plastic cover exist and at least two rear side lugs that are reciprocally formed in the lower-inner part of the plastic cover as a support for the flexible rear mid lug.
  • At least two front lugs are built reciprocally at the lower part of the plastic cover in a way that it is on the edge area against the rests.
  • the rests are positioned angularly to the center of the clamp for the reason that it can completely seat into the projections on the hose.
  • the flexible rear mid lug must - together with the rear side lugs and front lugs - contact the housing part at least on five ⁇ . points.
  • Figure 1 is general perspective view where the clamp mechanism is mounted on the hose.
  • Figure 2 side detail view that represents the tightening of the clamp on the hose via a screwdriver.

  • the invention relates to the fact that worm drive hose clamp, which is the sealing element on the hose-fitting connections that are to be found in the engine section especially in automotive sector, remains constantly at the same position while tightening on hoses (5).
  • the plastic cover (4) with rests (4.1 ) on it is structured on the housing part (2).
  • the clamp band (1 ) tightens the hose (5) the way that the screw (3) belonging to the clamp is rotated by a screwdriver (6).
  • the clamp may be tightened in an unsuitable position on the hose (5) by rotation around the hose (5) by the force that emerges during the tightening in accordance with the rotation axis of the screw (3).
  • a plastic cover (4) is added onto the housing part (2). As the rests (4.1) on the plastic cover (4) will rest on the projections (5.1 ) on the hose (5), it is provided that the clamp band (1) is always tightened at the same position on the hose (5).
  • the worm drive hose clamp comprises a clamp band (1 ) providing the tightening of the hose (5), a screw (3) that provides the decreasing diameter of the clamp band (1 ) by pulling band from the threads (1.1) on the clamp band (1 ) when turned, a housing part (2) that acts as the bearing during the transfer of the rotating force to the clamp band (1 ) by the screw (3) and carries the plastic cover (4) and a plastic cover (4) that provides, during the tightening, the tightening of the clamp constantly at the same position by preventing the rotating of the clamp on the hose (5).
