Abstract
The utility model discloses a crank-connecting rod mechanism which comprises a connecting rod, a box body and a sliding block. One end of the connecting rod is provided with a pin hole. The sliding block is provided with a pin hole. The connecting rod is connected with the sliding block in the way that a sliding block pin is inserted in the two pin holes in a matched and penetrating mode. The other end of the connecting rod is connected with a crank. The sliding block is in contact with the inner side wall of the box body and conducts rectilinear motion along the inner side wall of the box body. The sliding pin is sequentially divided into three sections from top to bottom, wherein the diameter of the first section is larger than that of the second section, the diameter of the second section is larger than that of the third section, and therefore the sliding pin is of a step shape. When the crank-connecting rod mechanism is installed, the third section of the sliding block pin enters the pin holes first, and due to the fact that the diameter of an inlet of the pin hole in the sliding block is larger than the diameter of the third section of the sliding block pin and the diameter of the second section of the sliding block pin, the third section and the second section of the sliding block pin do not make contact with the inner wall of the inlet of the pin hole in the sliding block during installation, and the wear area of the inner wall of the pin hole in the sliding block is reduced.
Description
Technical field
The utility model relates to a kind of driving mechanism, particularly a kind of connecting rod.
Background technique
In traditional connecting rod, connecting rod adopts slider pin to be connected with slide block joint, this slider pin is cylindric, because slider pin will closely cooperate with pin-and-hole, so when mounted, the interspersed pin-and-hole of slider pin can contact the hole wall of pin-and-hole, causes the wearing and tearing of hole wall, simultaneously because slider pin and pin-and-hole all become cylindrical, when slide block is done straight line motion along casing, slider pin easily, along the radial vibration of pin-and-hole, produces potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of connecting rod, and this connecting rod has reduced the wear area of slider pin and pin-and-hole when mounted.
For achieving the above object, the utility model provides following technological scheme: a kind of connecting rod, comprise connecting rod, casing and slide block, one end of connecting rod arranges pin-and-hole, pin-and-hole is set on slide block, connecting rod is connected with slide block by the interspersed slider pin of cooperation of two pin-and-holes, the other end of connecting rod is connected with crank, slide block is arranged in the inner chamber of casing, and slider pin sets gradually into three sections from top to bottom, and the diameter of first paragraph is greater than the diameter of second segment, the diameter that the diameter of second segment is greater than the 3rd section, becomes stepped.
Preferably, the second segment of the pin-and-hole on connecting rod and slider pin closely cooperates.
Preferably, pin-and-hole and slider pin on slide block closely cooperate, and become stepped.
Preferably, the two ends of slider pin arrange respectively slider pin tamponade.
Adopt technique scheme, a kind of connecting rod, comprise connecting rod, casing and slide block, one end of connecting rod arranges pin-and-hole, pin-and-hole is set on slide block, connecting rod is connected with slide block by the interspersed slider pin of cooperation of two pin-and-holes, the other end of connecting rod is connected with crank, slide block is arranged in the inner chamber of casing, slider pin sets gradually into three sections from top to bottom, and the diameter of first paragraph is greater than the diameter of second segment, the diameter that the diameter of second segment is greater than the 3rd section, become stepped, when this connecting rod is installed, first the 3rd section of slider pin enter pin-and-hole, because the pin-and-hole inlet diameter on slide block is greater than the 3rd section and the diameter of second segment of slider pin, so the 3rd of slider pin the section does not contact pin-and-hole entrance inwall with second segment when mounted, reduce the wear area of pin-and-hole inwall.
Pin-and-hole on connecting rod and the second segment of slider pin closely cooperate, pin-and-hole and slider pin on slide block closely cooperates simultaneously, become stepped, when slider pin interts in two pin-and-holes, because the diameter of slider pin second segment is greater than the 3rd section of pin-and-hole on slide block, so the 3rd section of the pin-and-hole on slide block stoped the radial motion of slider pin in pin-and-hole, in like manner, the diameter of slider pin first paragraph is greater than the diameter of pin-and-hole second segment, has therefore stoped slider pin along pin-and-hole radial motion; The two ends of slider pin arrange respectively slider pin tamponade, prevent that slider pin from directly contacting with cabinets cavity wall, avoids damaging slider pin.

Wherein, 1. connecting rod 2. casing 3. slider pin 4. pin-and-hole 5. slide block 6. pin-and-hole 7. slider pin tamponade 8. cranks.
Embodiment
Below in conjunction with accompanying drawing, the description by embodiment, is described further the utility model:
As Fig. 1, as Fig. 2, shown in Fig. 3 and Fig. 4, a kind of connecting rod of the utility model, comprise connecting rod 1, casing 2 and slide block 5, the head of connecting rod 1 arranges pin-and-hole 4, pin-and-hole 4 closely cooperates with the intermediate portion of slider pin 3, pin-and-hole 6 is set on slide block 5, pin-and-hole 6 also closely cooperates with slider pin 3, in the hole of pin-and-hole 6, shape is consistent with slider pin 3, slider pin 3 is divided into three sections, and the diameter of first paragraph is greater than the diameter of second segment, the diameter of second segment is greater than the 3rd section of diameter, become stepped, in like manner, pin-and-hole 6 is also divided into three sections, and the diameter of first paragraph is greater than the diameter of second segment, the diameter of second segment is greater than the 3rd section of diameter, the second segment diameter of pin-and-hole 6 is consistent with the diameter of pin-and-hole 4, connecting rod 1 is connected with slide block 5 with pin-and-hole 6 through pin-and-hole 4 by slider pin 3, the tail end of connecting rod 1 is connected with crank 8, slide block 5 contacts with the internal chamber wall of casing 2, and can do straight line motion along the internal chamber wall of casing 2, when this connecting rod is installed, the 3rd section of part of slider pin 3 starts to enter pin-and-hole, because pin-and-hole 6 diameters on slide block 5 are greater than second segment and the 3rd section of diameter of slider pin 3, so the end of slider pin 3 does not contact the inwall of pin-and-hole 4 and pin-and-hole 6 when mounted, thereby reduce the wear area of pin-and-hole 4 and pin-and-hole 6 inwalls, simultaneously, when slider pin 3 interts at pin-and-hole 4 and pin-and-hole 6 when interior, because the second segment diameter of slider pin 3 is greater than the aperture of the 3rd section of pin-and-hole 6, therefore pin-and-hole 6 has stoped the end slip of slider pin 3 to pin-and-hole 6, in like manner, the first paragraph diameter of slider pin 3 is greater than the diameter of the second segment of pin-and-hole 4 and pin-and-hole 6, therefore stoped slider pin 3 can not radially slide along pin-and-hole 6, the two ends of slider pin 3 arrange respectively slider pin tamponade 7, prevent that slider pin 3 from directly contacting with casing 2 madial walls, avoids damaging slider pin 3.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
