Definitions

  • the present invention relates to pliers for gripping round bodies, such as, for example, spark plug connectors which have seams.
  • Round bodies which are arranged in hole-like depressions, are often difficult to grasp and handle. This applies in particular to spark plug connectors that are attached to spark plugs screwed into recesses in the engine block. When attempting to grip such spark plug plugs with conventional pliers, the plugs are often damaged, especially if they have ceramic components. The tools previously used to grip such spark plug connectors or similar devices only fulfill their purpose incompletely.
  • the object of the present invention is to create a pair of pliers for gripping such round bodies, in particular spark plugs, which allow easy and simple gripping without damaging them and which nevertheless ensure that the round body is held firmly in the pliers.
  • the pliers according to the invention are suitable for gripping round bodies which have a fold seam, such as for example different spark plug connectors which are composed of two semicircular parts which are connected to one another by a fold seam. Such spark plug plugs are used for. B. made of two metal parts that are connected by a seam, these embodiments have the advantage that ceramic parts can be integrated into the spark plug connector. However, these ceramic parts are very prone to breakage, so that they are easily damaged when gripped with conventional pliers.
  • the pliers according to the invention are suitable for pulling off such spark plug plugs from spark plug holes located deep in depressions without damaging the sensitive ceramic bodies.
  • the contact body in the form of a half cylinder, which is adapted to the shape of the spark plug connector, rests with its cylindrical surface on the outer surface of the spark plug connector.
  • By moving the locking pins into the gripping position they rest on the fold seams in such a way that the fold seams are enclosed between the radial contact edges of the half-cylinder and locking pins.
  • the dimension of the distance A between the locking pins and the contact edges can be dimensioned so that the seams are clamped in between.
  • spark plug connectors have structural parts protruding from the round body, which is the case with most spark plug connectors with seams.
  • the cylinder surface with recesses which are adapted to the protruding structural parts and into which these structural parts are received when they are gripped with the pliers, as a result of which the plunger plugs have a particularly secure hold.
  • the locking pins are preferably designed as cylindrical pins which are guided in a guide in which they can be moved from an upper release position into a lower gripping position by means of a lever.
  • the distance A of the locking pins from the contact edges is preferably approximately 1 to 10 mm, in particular approximately 2 to 8 mm.
  • the lever for actuating the locking pin can have locking devices in the upper release position and in the lower gripping position, which lock these positions against a certain resistance.
  • the locking devices can contain, for example, spring-loaded balls which can be snapped into locking recesses.
  • FIG. 1 shows a pair of pliers, FIG. 1 a showing a front view, FIG. 2 b a side view and FIG. 1 c a view from below;
  • FIG. 2 shows a further embodiment of a pair of pliers with locking devices, FIG. 1 a a front view, FIG. 2 b a side view and FIG. 2 c a view from below.
  • the pliers contain a contact body 12 in the form of a half cylinder, the inner cylindrical surface 14 of the outer shape of the round body to be gripped, z. B. the spark plug connector is adjusted.
  • the contact body 12 is placed against the body to be gripped, the latter is thus gripped by the contact body 12.
  • the round body has fold seams, the radial contact edges 16 of the half cylinder 12, which lie radially opposite one another in the course of the diameter of the half cylinder, lie against the fold seams.
  • REPLACEMENT BLADE (RULE 26) is arranged pivotably, the locking pins 20 movably connected to the lever 24 via a joint 34 can be pivoted from an upper release position into a lower gripping position, as shown in FIGS. 1b and 2b.
  • the fold seams of the round body are held between the radial contact edges 16 and the locking pins 20.
  • Recesses 20 in the contact body 12 can accommodate structural parts which protrude from the round body, as a result of which the round body is additionally held in the pliers.
  • the pliers with the contact body 12 are placed on the round body, the lever 24 is actuated, whereby the locking pins 24 are moved in front of the contact edges 16 and the seams are enclosed between them. By pulling the lever 24, the round body is gripped and pulled off.

Abstract

L'invention concerne une pince pour saisir des corps ronds présentant des joints pliés, par exemple des cosses de bougies d'allumage. L'invention est caractérisée par un élément d'appui (12) en forme de demi-cylindre adapté à la forme du corps rond et pouvant être appuyé avec une surface cylindrique (14) sur une surface extérieure du corps rond entre les joints pliés. Cet élément d'appui peut également être appuyé sur les joints pliés avec des arêtes d'appui radiales (16) adjacentes à la surface cylindrique (14). Cette pince comprend deux broches de blocage (20) qui, dans la position de serrage, peuvent être déplacées devant les arêtes d'appui (16) parallèlement à ces dernières, à une distance (A) des arêtes d'appui (16) et qui, dans la position de libération, peuvent être éloignées des arêtes d'appui (16).
