Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
As shown in fig. 1-4, a transmission chain fixing bracket and a truck roof transmission mechanism with the same, the transmission chain fixing bracket includes a bracket body 11, the bracket body 11 includes a pulley connecting portion 1, a backward tilting extension portion 2 and a chain connecting portion 3 which are connected in sequence, the pulley connecting portion 1 is located at the front upper corner of the backward tilting extension portion 2, the chain connecting portion 3 is located at the bottom end of the backward tilting extension portion 2, and the orthographic projection of the chain connecting portion 3 is located behind the orthographic projection of the pulley connecting portion 1; since the pulley connecting portion 1 is used for connecting the rear pulley 10 and the chain connecting portion 3 is used for connecting the transmission chain 13, the rear inclined extending portion 2 is inclined obliquely downward, and the final chain fixing position is also positioned obliquely downward of the rear pulley 10.
The chain connecting part 3 is specifically a long-strip-shaped locking part extending along the front-back direction, the long-strip-shaped locking part comprises an upper clamping plate 8 and a lower clamping plate 7 which are arranged in parallel, the outer side of the upper clamping plate 8 and the bottom end of the backward tilting extending part 2 are integrally formed, and a plurality of alignment locking holes 9 are formed in the upper clamping plate 8 and the lower clamping plate 7 from front to back; when the device is installed, the upper clamping plate 8 and the lower clamping plate 7 are used for clamping the transmission chain 13, and the locking bolt or the pin shaft is used for penetrating through the alignment locking hole 9 and the hole of the transmission chain 13 and being locked together to complete fixation; besides the upper and lower clamping plate structures, in other embodiments, a thin box-shaped structure composed of an upper part and a lower part, or a long strip-shaped clamping structure clamped from two sides of the transmission chain 13 can be used, and the long strip-shaped locking piece can prolong the acting point of the long strip-shaped locking piece and the transmission chain 13, so that when the pulley is pulled by the transmission chain 13 to slide, the tilting amplitude of the chain connecting part 3 can be effectively reduced, and the pulley can run more stably.
The pulley connecting part 1 is of a vertical flat plate structure, and four rectangular mounting threaded holes 6 are formed in the pulley connecting part 1; the structure can be more stable by installing four screws at the rear lower corner of the rear pulley 10.
The front lower corner of the backward tilting extension part 2 is also provided with a chamfer bevel edge 4, the chamfer bevel edge 4 can better avoid the driving gear 12, and the rear pulley 10 can be completely accommodated in the cap peak 15; the rear upper edge of the backward inclined extension part 2 is in a volute curve 5, so that the appearance is attractive, and the assembly is firmer.
The truck roof transmission mechanism comprises a driving gear 12, a transmission chain 13 located on the side face of a carriage, a rear trolley 10 located at the rear end of the roof and a transmission chain fixing support, wherein the front end of the transmission chain 13 is wound on the driving gear 12, the driving gear 12 is installed on a front carriage plate 14, the trolley connecting part 1 is fixedly connected with the rear lower corner of the rear trolley 10, and the chain connecting part 3 is fixedly connected with the transmission chain 13.
The working principle is as follows:
because the retroversion extension part 2 inclines towards the oblique lower side, the connection part of the transmission chain 13 and the chain connection part 3 is finally positioned at the oblique lower side of the rear pulley 10, the transmission chain 13 is pulled by the driving gear 12 to move towards the front carriage plate 14, the rear pulley 10 can be driven to move forwards, and when the rear pulley 10 moves to the position right above the driving gear 12, the fixed position of the transmission chain 13 cannot interfere with the transmission chain 13, so that the rear pulley 10 can drive the canopy to be completely accommodated in the visor 15.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
