The utility model adopts the following technical scheme:
the utility model provides a V type telescopic bracket spring mounting structure, includes upper pipe, below pipe, hinge, spring, connecting rope, screw rod and nut, upper pipe and below pipe are in the same place through the hinge rotation, spring one end is passed through the screw rod and is set up on the below pipe with the nut, connecting rope one end is together fixed with the spring, and the connection stay cord other end is fixed on upper pipe, still includes side pipe box clamp and adjusting bolt, the slide has been seted up on the pipe wall of below pipe, the screw rod is located in the slide, side pipe box clamp is fixed below manage, adjusting bolt installs on side pipe box clamp, adjusting bolt supports nut or screw rod.
Fix the screw rod activity on the below pipe in this structure, just can change the position of screw rod on the slide when twisting adjusting bolt like this, when the screw rod position takes place on the slide, can change the tensile volume of spring, and the change of the tensile volume of spring can change the elasticity size, so when the V type telescopic bracket who adopts this mounting structure installs the flexible curtain that patent CN206819044U shows, V type telescopic bracket's elasticity can be adjusted, can guarantee like this that the curtain can be stretched out completely, and the curtain can not appear the fold after stretching out, even the fold has appeared in the curtain in the use, still can let the curtain stretch out through twisting adjusting bolt.
In conclusion, the mounting structure can adjust the position of the screw rod by screwing the adjusting bolt, change the stretching amount of the spring by changing the position of the screw rod, change the stretching amount of the spring can change the elastic force of the V-shaped telescopic support, and the adjustment is convenient.
Optionally, the adjusting bolt is vertically abutted against the screw or the nut.
The adjusting bolt vertically props against the screw rod or the nut to ensure the propping strength of the screw rod and the nut, and the screw rod and the nut cannot slip off.
Optionally, be provided with two slides on the below pipe, and two slides are parallel to each other, the both ends of screw rod are in the same place with a nut cooperation separately, and the nut is located outside the below pipe, and the nut pastes tight slide.
Optionally, the adjusting bolt is a hexagon socket head cap screw.
The inner hexagon bolt is convenient to adjust
Optionally, the connecting rope is a steel wire rope.
The utility model has the advantages that: this mounting structure can adjust the position of screw rod through twisting adjusting bolt, changes the tensile volume of spring through the position that changes the screw rod, and the elasticity size of V type telescopic bracket can be changed in the change of spring tensile volume, and it is convenient to adjust.
Description of the drawings:
fig. 1 is a schematic diagram of a fixing structure of a spring on a lower pipe.
The figures are numbered: 1. spring, 2, lower pipe, 201, slide, 3, adjusting bolt, 4, square pipe collet, 5, nut, 6, screw rod.
The specific implementation mode is as follows:
the present invention will be described in detail below.
Referring to fig. 1 and shown in fig. 3 among the patent CN206819044U, a V type telescopic bracket spring 1 mounting structure, including upper pipe, lower side pipe 2, the hinge, spring 1, connect the rope, screw rod 6 and nut 5, upper pipe passes through the hinge rotation with lower side pipe 2 and links together, 1 one end of spring passes through screw rod 6 and nut 5 sets up on lower side pipe 2, it is together fixed with spring 1 to connect rope one end, it is fixed on upper pipe to connect the stay cord other end, still include square pipe collet 4 and adjusting bolt 3, slide 201 has been seted up on the pipe wall of lower side pipe 2, screw rod 6 is located slide 201, square pipe collet 4 is fixed on lower side pipe 2, adjusting bolt 3 installs on square pipe collet 4, adjusting bolt 3 supports nut 5 or screw rod 6.
