Retaining device and wear element for excavators and the like

Abstract

The present invention relates to a retaining device and a wear element, preferably a female part, for ensuring the retention between the female part and a male part, used in excavators and the like. The female part has a cavity and the male part has a projection which is inserted into the cavity of the female part, both parts being coupled to each other due to the use of a retaining device together with at least one pin which at least partially crosses through the female part, the retaining device and the male part.

1 . A retaining device for a female part for excavators and the like, said female part having a cavity for receiving a nose of a male part, and said device comprising a body with a hollow space determined by an upper section, lower section, opposite from the previous one, and a rear section characterised in that it has a support element with elastic properties joined to one end of said body for fastening the retaining device in the cavity of the female part. 
     
     
         2 . The device, according to  claim 1 , characterised in that the support element has a body with a first outer base and a second base opposite from the first base. 
     
     
         3 . The device, according to  claim 2 , characterised in that it comprises a data storage code in the first base of the prismatic body of the support element. 
     
     
         4 . The device, according to  claim 1 , characterised in that the body is an elongated body wherein the upper section and the lower section are parallel and are separated by the rear section, this determining a first end substantially perpendicular to both upper and lower sections, and each of these two sections having a front section with a free end at a second end opposite from the rear section, such that both free ends are joined to the support element. 
     
     
         5 . The device, according to  claim 4 , characterised in that the second base of the support element comprises an opening into which the ends of the elongated body are inserted for the joining thereof to the support element. 
     
     
         6 . The device, according to  claim 4 , characterised in that the support element comprises two slits for the insertion thereof by pressure of the free ends of the elongated body. 
     
     
         7 . The device, according to  claim 5 , characterised in that the support element has an L-shaped longitudinal cross section. 
     
     
         8 . The device, according to  claim 1 , characterised in that the body is a laminar body wherein the upper section and the lower section are parallel and are separated by the rear section and a front section parallel to said rear section, determining a closed frame, and having at least one flexible flange joined at one of the ends thereof to one of the sections of said body by the hollow space, the free end of the flange being opposite from the joining end with the section, away from the hollow space and at least the front section joined to the support element. 
     
     
         9 . A wear element, characterised in that it is a female part with a body with a cavity comprising an inner end, an open end and side walls, wherein at least one of said walls has a first through hole and a second through hole, located between the inner end of the cavity and the first hole, with a retaining device according to  claim 1  inside the aforementioned cavity, with the support element inserted into the second hole with the second base thereof inside the cavity and the first base thereof facing the outside through the second hole. 
     
     
         10 . The wear element, according to  claim 9 , characterised in that the data storage code is arranged on the first base of the retaining device. 
     
     
         11 . The wear element, according to  claim 9 , characterised in that the thickness of the side wall is larger than the distance between the first and second bases of the support element. 
     
     
         12 . The wear element, according to  claim 9 , characterised in that the cross section of the second hole is smaller than the cross section of the support element. 
     
     
         13 . The wear element, according to  claim 9 , characterised in that the support element is inserted by pressure into the second hole. 
     
     
         14 . The wear element, according to  claim 9 , characterised in that the first hole is close to the second hole. 
     
     
         15 . The wear element, according to  claim 10 , characterised in that it comprises a data storage code accessible from outside the female part.
