Abstract

The utility model discloses an elevator door lock gib head contact. The technical scheme who adopts is equipped with the arc connecting portion including the main square contact base of being made by the copper product, this square contact base one side, is equipped with counter sink, its characterized in that in the middle of these arc connecting portion: square contact base upper surface set up a transverse slotting or two vertical flutings side by side, be equipped with the silver bar of fitting mutually rather than the shape in transverse slotting or the vertical fluting, the silver bar with pass through stamping connection between transverse slotting or the vertical fluting. The utility model discloses an elevator door lock gib head contact has following advantage: 1, through the design of bank's strip, under the prerequisite that does not influence its performance, silver -colored use amount has significantly reduced to manufacturing cost has been reduced, 2, through stamping connection, make and realize seamless connection between silver bar and the contact base between silver bar and transverse slotting or the vertical fluting, make its connection inseparabler more to improve the stability of product.

Description

A kind of door lock of elevator gib head contact
Technical field
This utility model is related to a kind of contact being applied to door lock of elevator gib head.
Background technology
Elevator door lock structure include hammerlock and be arranged on this hammerlock front end gib head on contact, this contact with electrically Match in contact.Described contact is the critical elements of elevator door switch contact, to its conductive and sparkproof performance requirement all very Height, traditional contact structures are the whole surface one layer of silver layers of setting in contact base, because silver is precious metal material, lead to it Cost is very high.And in use, silver layer multi-section belongs to inactive area, so leads to the waste of material.Therefore, produce One kind is material-saving, and does not affect the technical barrier that the contact of its performance is that current urgent need solves.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple and reliable for structure and low cost elevator door latch hook Head contact.
For solving the above problems, the technical solution adopted in the utility model includes the square contact bottom being mainly made up of copper material Seat, this square contact base side is provided with arc connecting portion, be provided with counter sink in the middle of this arc connecting portion it is characterised in that:Institute The square contact base upper surface stated arranges a transversal slotting or two longitudinal grooveds side by side, described transversal slotting or longitudinal direction It is provided with the Rhizoma Humatae Tyermanni fitted with its shape phase, in fluting between described Rhizoma Humatae Tyermanni and described transversal slotting or longitudinal grooved by punching press even Connect.
Described door lock of elevator gib head contact it is characterised in that:The section of described transversal slotting or longitudinal grooved is trapezoidal.
Door lock of elevator gib head contact of the present utility model has the advantage that:1st, pass through the design of bank's bar, do not affecting On the premise of its performance, greatly reduce the usage amount of silver, thus reducing production cost;2nd, Rhizoma Humatae Tyermanni and transversal slotting or longitudinal direction Pass through stamping connection between fluting, make to realize between Rhizoma Humatae Tyermanni and contact base being seamlessly connected so as to be connected tightr, thus Improve the stability of product.
With reference to Figure of description, this utility model is described further.
Brief description
Fig. 1 is the structural representation of this utility model door lock of elevator gib head contact, the structure of display transversal slotting;
Fig. 2 is the exploded view of Fig. 1;
Fig. 3 is the structural representation of this utility model door lock of elevator gib head contact, the structure of display longitudinal grooved;
Fig. 4 be Fig. 3 look up exploded view.
Specific embodiment
Shown in reference picture 1-4, door lock of elevator gib head contact of the present utility model, including mainly by copper material make square touch Head base 1, this square contact base 1 side is provided with arc connecting portion 2, is provided with counter sink 3 in the middle of this arc connecting portion 2, described Square contact base 1 upper surface one transversal slotting 4 or two longitudinal grooveds 5 side by side are set, the depth of described fluting is 1mm about.It is provided with the Rhizoma Humatae Tyermanni 6 fitted with its shape phase, described Rhizoma Humatae Tyermanni 6 is horizontal with described in described transversal slotting 4 or longitudinal grooved 5 Pass through stamping connection between fluting 4 or longitudinal grooved 5.Described stamping connection refers to put into Rhizoma Humatae Tyermanni in the fluting of contact base Afterwards, by pressing equipment(As punch press)To its punching press, sheet metal component is made to be connected with each other using the plastic deformation of metal.By punching press even Connect and replace traditional welding, improve connection speed and quality.
Optimize such scheme further, the section of described transversal slotting 4 or longitudinal grooved 5 is trapezoidal.By trapezium structure Fluting design, have the advantages that to place Rhizoma Humatae Tyermanni is convenient, contact surface is big and stamping connection after connect even closer.
Upper described, not this utility model is done with any pro forma restriction although this utility model is implemented with preferable Case discloses as above, but is not limited to this utility model, and any those skilled in the art, without departing from this In the range of bright technical scheme, when the structure of available the disclosure above and technology contents are made a little change or are modified to equivalent change Change equivalence enforcement case, but every content without departing from technical solution of the present invention, according to the present invention technical spirit to Any simple modification, equivalent variations and modification that upper case study on implementation is made, all still belong to technical solutions of the utility model scope.
