Abstract
The utility model provides a tightening and loosing device that is convenient to tie and loose, which is characterized in that a contact (2)of a fastening strip (1) is connected with a lever (4) at the back end (3) of a lever, a contact (12) is connected with a lever (10) at the back end (11) of a lever, a lever (4) is connected with a lever (10) through an axis (5), a negative clip (6) is arranged on a lever front (7) of the lever (4), a positive clip is arranged on a lever front (8) of the lever (10), and the negative clip (6) and the positive clip (9) can be mutually clamped when in use. The apparatus is mainly used to bind and fasten a dowel joint hose and materials conveniently and rapidly.
Description
The utility model relate to a kind of can be easily with pipe or the fastening apparatus of thing binding, especially convenient interim binding is fastening, and it is fastening also very convenient to unclamp binding, can repeated use tie up the just quick binding loosening device of loose measure.
At present, existing pipeline tense-lax device has 1. spring fastener: fastening strength can not be regulated; Tightening device must break annual spring into two with one's hands, just can install, and comparatively difficulty of practicality is installed; The pipe that has connected can't be fastening, and field of application is little; 2. screw is fastening: must screw be tightened utility, and could fastening success.Practical inconvenient, easily cause the stripped thread etc. can't be fastening, field of application is little.Tying up of article is disposable tying up admittedly mostly, can not repeated use or not easy to operate, deficiency such as tool equipment is big.And two kinds of technology of binding pipeline and thing can not be general, is their bigger weak point.
The utility model provide the fastening convenience of a kind of binding firmly, decontrol simple and repeatedly used tense-lax device.
The technical scheme that its technical matters that solves the utility model adopts is: respectively there is contact on the both sides at restraint zone, and contact is connected with lever rear end, in the middle of the lever axle are arranged, and grab is installed on the lever or on the restraint zone.When binding need bundle when fastening, this tense-lax device is placed on binding need bundlees fastening place, according to required strength with lever front end (lever front end: the unconnected end of lever and restraint zone) apply external force to fastening direction, external force makes the tension of lever rear end (lever rear end: lever and restraint zone bonded assembly one end) bonded assembly restraint zone by axle, make the binding binding fastening, simultaneously grab is blocked at this state, after the external force cancellation, this tense-lax device bundlees fastening binding with this external force, and stably keeps equilibrium of forces; When needs unclamp binding, grab is broken away from screens, binding can be unclamped.Fasteningly need easily for bundling, can be set to monolithic devices, open-type and split simple type by this tense-lax device.This technology effectively utilizes the lever principle of mechanics, and restraint zone is strained; Utilize the equilibrium principle of mechanics, the fastening state of binding is maintained, reach the static balancing of binding after fastening.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 ties up the just constructional drawing of quick binding loosening device embodiment of loose measure.
1. restraint zones among the figure, 2. contact, 3. lever rear end, 4. lever, 5. spool, 6. cloudy grab, 7. lever front end, 8. lever front end, 9. positive grab, 10. lever, 11. lever rear ends, 12. contacts.
In Fig. 1, the contact (2) of restraint zone (1) is located at lever rear end (3) with lever (4), contact (12) is located to be connected at lever rear end (11) with lever (10), lever (4) intersects with lever (10) and is connected by axle (5), cloudy grab (6) is installed in the lever front end (7) of lever (4) and locates, sun grab (9) is installed in the lever front end (8) of lever (10) and locates, and cloudy grab (6) and positive grab (9) can block in use mutually.When needing binding fastening, restraint zone (1) is enclosed within the place that needs binding fastening, external force acts on lever front end (8) and lever front end (7) move toward one another, make lever rear end (11) and lever rear end (3) move toward one another, drive restraint zone (1) upper contact (2) and contact (12) move toward one another, tension restraint zone (1), cloudy grab (6) blocks mutually with positive grab (9) simultaneously, external force bundlees fastening finishing after disappearing; When needing fastening the unclamping of binding, grab is broken away from screens, it is fastening to unclamp binding.
In embodiment illustrated in fig. 2, restraint zone (1) upper contact (2) is located at lever rear end (3) with lever (4), contact (12) is located to be connected at lever rear end (11) with lever (10), lever (4) is connected by axle (5) with lever (10) is staggered, cloudy grab (6) is installed in the lever front end (7) of lever (4) and locates, sun grab (9) is installed in the lever front end (8) of lever (10) and locates, and cloudy grab (6) and positive grab (9) can block in use mutually.When needing binding fastening, restraint zone (1) is enclosed within the place that needs binding fastening, when external force acts on lever front end (7) and lever front end (8) move toward one another, lever rear end (3) and the opposing motion of lever rear end (11), drive restraint zone (1) upper contact (2) and the opposing motion of contact (12), tension restraint zone (1), cloudy grab (6) blocks mutually with positive grab (9) simultaneously, external force bundlees fastening finishing after disappearing; When needing fastening the unclamping of binding, grab is broken away from screens, it is fastening to unclamp binding.
Claims (2)
1. tying up the just quick binding loosening device of loose measure is by restraint zone, lever, grab combination, be characterized in: the contact (2) of restraint zone (1) is located at lever rear end (3) with lever (4), contact (12) is located to be connected at lever rear end (11) with lever (10), lever (4) intersects with lever (10) and is connected by axle (5), cloudy grab (6) is installed in the lever front end (7) of lever (4) and locates, sun grab (9) is installed in the lever front end (8) of lever (10) and locates, and cloudy grab (6) and positive grab (9) can block in use mutually;
2. the just quick binding loosening device of loose measure of tying up according to claim 1, be characterized in: lever (4) is connected by axle (5) with lever (10) is staggered.
