Problems solved by technology
[0002] Almost all the elastic rope devices currently used have defects such as insufficient shrinkage range, low shrinkage force, high production cost, cumbersome installation process, difficult debugging, and unstable performance, especially when the heavy hammer elastic rope device is installed. When on the elevator hall door, there is still a hidden danger of falling and hurting people

Embodiment Construction
[0036] First put the supporting legs of the shorter intermediate butterfly spring 7 with a suitable number of supporting legs in a straight line, and the semicircular openings are opposite. Insert it in the inner notch of the inner concave jacket 8, first put the spring washer 15 on the bolt, and then put the sleeve on the outside of the spring washer , and then put on the flat washer 13, then string it in from the long slot hole in the middle of the inner plane of the left fixed plate 5, and then put the flat washer on the sleeve 11 , and finally put the T-shaped nut 12 on the head of the bolt 10 and tighten it, the continuous connection of the middle butterfly spring 7 with shorter supporting legs and the positioning on the fixed plate 5 are all performed in this way until the shorter supporting legs This is true for the connection of the terminal butterfly spring 6 and the middle butterfly spring 7, as well as the positioning on the fixing plate 5.

The invention discloses a butterfly-shaped rope tension regulator. An indent clamping sleeve and a T-shaped nut are arranged between an upper terminal butterfly-shaped spring and a lower terminal butterfly-shaped spring, and an assembling unit is used for connecting an intermediate butterfly-shaped spring, the upper terminal butterfly-shaped spring and the lower terminal butterfly-shaped spring, so that a crossed butterfly-shaped spring combination is formed; then, two of the crossed butterfly-shaped spring combinations are assembled between two fixed plates to form an alternative combination with the left and the right crossed butterfly-shaped spring combinations; and an upper fixing fame and a lower fixing frame are respectively arranged on parts close to top ends at two ends of the two fixed plates, and then a rope and guiding wheels are arranged. The butterfly-shaped rope tension regulator disclosed by the invention has the beneficial effects of: 1, large contraction range and large contraction force; 2, low production cost, simple installation process, convenience for debugging and stable performance; and 3, capability of eliminating the phenomenon that people are possibly injured by the falling rope tension regulator which is used by being arranged on a hoistway door. The butterfly-shaped rope tension regulator comprises the parts as follows: 1, the upper fixing frame, 2, the lower fixing frame, 3, the fixed plates, 4, the terminal butterfly-shaped springs, 5, the intermediate butterfly-shaped spring, 6, the indent clamping sleeve, 7, the T-shaped nut, and 8, rope end bolts.
Description
technical field [0001] The present invention relates to an elastic cord device, more specifically to a butterfly type elastic cord device. Background technique [0002] Almost all the elastic rope devices currently used have defects such as insufficient shrinkage range, low shrinkage force, high production cost, cumbersome installation process, difficult debugging, and unstable performance, especially when the heavy hammer elastic rope device is installed. There is also the hidden danger of falling and hurting people when on the elevator hall door. [0003] purpose of invention [0004] Purpose of the present invention is exactly in order to overcome and eliminate above-mentioned defect and hidden danger. Contents of the invention [0005] In the middle of the upper and lower terminal butterfly springs, use a concave jacket, a T-shaped nut and an assembly to connect the middle butterfly spring and the upper and lower terminal butterfly springs to form a cross-shaped butt...
