Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further:
One as Figure 1-Figure 4 is stretched threaded rod 2, including swingle 21 and respectively with the first swivel joint 22 and the second swivel joint 23 of swingle 21 two ends threaded engagement.
Described swingle 21 includes swingle main body 211 and the first threaded joints being separately positioned on swingle main body 211 two ends and the second threaded joints.The structure of described first threaded joints and the second threaded joints is identical, all includes weld bolt 212 and the fastening screw nut 213 set gradually.Described weld bolt 212 is weldingly connected with the end of described swingle main body 211.It is provided with the first through hole 214 in the middle of described swingle main body 211, and its stage casing is provided with clamping groove 215.Described weld bolt 212 includes being provided with the second through hole 218 in the middle of bolt head 216 and the screw rod 217 being sequentially connected, and described weld bolt 212.It is provided with third through-hole 219 in the middle of described fastening screw nut 213.Described first through hole the 214, second through hole 218 is connected with third through-hole 219.Described screw rod 217 is connected to the end of described first through hole 214.Described clamping groove, for convenient wrench clamping.
Described first swivel joint 22 is identical with the structure of the second swivel joint 23, all includes threaded rod 221 and the bearing 223 set gradually, and the end of described threaded rod 221 is connected with the lateral wall of described bearing 223 by fittings body 222.Described threaded rod 221 is provided with external screw thread.Described threaded rod 221 sequentially passes through third through-hole the 219, second through hole 218 and stretches in the first through hole 214, and described threaded rod 221 is threadeded with described third through-hole the 219, second through hole 218 respectively.
The assembling structural representation of flexible threaded rod as shown in Figure 5.In the figure, the fan 3 including refrigerating module 4, being connected on refrigerating module 4, the Fan Transmission-mechanism 5 being connected with fan 3, the water tank upper bracket 1, the Support for water tank 8 being connected with refrigerating module 4 lower end by cushion 10 and the drive mechanism mounting bracket 6 that Fan Transmission-mechanism 5 is connected on car load crossbeam 9 that are connected with the upper end of refrigerating module 4 by flexible threaded rod 2；The lower end of described water tank upper bracket 1 is detachably connected on car load crossbeam 9；The bottom of described drive mechanism mounting bracket 6 is connected with described Support for water tank 8 by connecting support 7.
Specifically, by the hand of spiral of the external screw thread direction of the threaded rod of the first swivel joint, the external screw thread direction of the threaded rod of the second swivel joint, the hand of spiral of the first threaded joints and the second threaded joints is configured, so when the swingle rotated between the first swivel joint and the second swivel joint, first swivel joint and the second swivel joint elongate or shorten (the i.e. first swivel joint and the second swivel joint are exposed at being increased or decreased of length outside swingle) simultaneously, thus realize the flexible of whole flexible threaded rod.
Due to bus engine belt pulley, the drive of Fan Transmission-mechanism, tensioned fit is needed between the transition wheel three of Fan Transmission-mechanism, and the mounting distance between fan and refrigerating module needs to meet certain requirement, therefore, can be by the length of the flexible threaded rod of regulation, make the inclination angle of adjustment refrigerating module, thus bus engine belt pulley can not only be made, the drive of Fan Transmission-mechanism, can tensioned fit between the transition wheel three of Fan Transmission-mechanism, the mounting distance between fan and refrigerating module is made to meet certain requirement, the rigging error of electromotor can also be eliminated.Because the bottom of refrigerating module is connected with Support for water tank by cushion, so, it is to be flexible coupling between bottom and the Support for water tank of refrigerating module, when being regulated the inclination angle of refrigerating module by the length adjusting flexible threaded rod, does not interferes with the stability being connected between the bottom of refrigerating module and Support for water tank.
Embodiment described above is only to be described preferred implementation of the present utility model; not scope of the present utility model is defined; on the premise of without departing from this utility model design spirit; various deformation that the technical solution of the utility model is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that this utility model claims determine.
