Abstract
The utility model provides a fixing structure for an auxiliary arm installing bracket and an extending bracket of an automobile crane, which comprises a fixed bracket and the extending bracket connected with the fixed bracket, wherein the fixed bracket is connected with the extending bracket, one side of the connecting end adopts articulating connection, and the other side adopts spigot type connection; the fixed bracket and the extending bracket are closely locked at the spigot position by a pin shaft, a locking spring and a knurled nut; the pin shaft penetrates through the spigot overlapping part, the locking spring is arranged at the inner part of the pin shaft, and one end of the pin shaft is locked by the knurled nut. The fixing structure is characterized in that the knurled nut can be used for locking the two brackets, adjusting the length of the pin shaft and pulling a handle; therefore, the whole structure is simple and the processing is easy.
Description
Technical field
The utility model relates to and a kind of the connection uses the fixing pattern of simple structure of exempting from detachable connecting of automobile crane subsidiary arm mounting bracket and its prolongation support.
Background technology
At present, known automobile crane subsidiary arm support and its prolongation support fixedly pattern have two kind one to be the pattern that needs the dismounting bearing pin, though this structural shape structural shape is simple, but be not easy to personnel operation, the 2nd, exempt from detachable, and the present fixedly pattern of exempting from detachable also is a complex structure, processing difficulties.
The utility model content
The purpose of this utility model provides a kind of personnel operation that can make and makes things convenient for a kind of fixed sturcture of exempting from detachable simple in structure again, the while handling ease.
The technical scheme that the utility model provides is:
The fixed sturcture of automobile crane subsidiary arm mounting bracket and its prolongation support, comprise fixed support and prolong support with the fixed support bonded assembly, fixed support is connected with the prolongation support, and adopt hinged in a side of coupling end, opposite side adopts socket type to connect, and locks by bearing pin, locking spring, knurled nut at spigot, passes bearing pin at the socket overlapping, the inside of bearing pin is equipped with locking spring, and an end of bearing pin is locked with the knurled nut.
Unique distinction of the present utility model is, can the lock handle of two supports, adjusting cotter shaft length, pulling of knurled nut makes total simple, handling ease.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structure principle chart of the fixed sturcture of automobile crane subsidiary arm mounting bracket described in the utility model and its prolongation support;
Fig. 2 is the constitution diagram of the fixed sturcture of automobile crane subsidiary arm mounting bracket and its prolongation support;
Fig. 3 is an A place cut away view among Fig. 2.
The specific embodiment
As Figure 1-3, the fixed sturcture of automobile crane subsidiary arm mounting bracket and its prolongation support, comprise fixed support 1 and prolong support 2 with fixed support 1 bonded assembly, fixed support 1 with prolong support 2 and be connected, and adopt hingedly 7 in a side of coupling end, opposite side adopts the connection of socket 6 formulas, and at socket 6 places by 5 lockings of bearing pin 3, locking spring 4, knurled nut, pass bearing pin 3 at socket 6 overlappings, the inside of bearing pin 3 is equipped with locking spring 4, and an end of bearing pin 3 is locked with knurled nut 5.
Bearing pin 3, locking spring 4, knurled nut 5 and the two stands that need fix.Need the mounting hole aperture of fixing two stands to determine by the upper and lower side diameter dimension of bearing pin 3 according to principle of work.Fixedly knurled nut 5 of screw thread has been attacked in bearing pin 3 lower ends.Locking spring 4 is filled to the lower end polished rod portion of bearing pin 3, and bearing pin 3, locking spring 4, knurled nut 5 are filled to be needed on the movable support.
Working process: need to prolong auxiliary mounting bracket 1, use when prolonging support 2, spur knurled nut 5 downwards, this moment, two stands was in no restrained condition, need the support 2 of rotation prolongation simultaneously, promote to prolong support 2 and directly can secure on the fixed support 1, just can use prolonging support 2.Do not use when prolonging support, spur knurled nut 3 downwards, promote to prolong the locking position of support 2, spur knurled nut 5 once more downwards to locking (locking of knurled nut and support 1) fully to fixed support 1 place.
Unique distinction of the present utility model is, can the lock handle of two supports, adjusting cotter shaft length, pulling of knurled nut makes total simple, handling ease, and entire work process is simple to operate, exempts from dismounting.
