Description
Technical field
The utility model relates to a kind of securing means with the screw screw rod.
Background technique
The securing means of band screw screw rod often need be used in life; Patent of invention like application number 00137411.7; The patent of invention of application number 200910310941.4; The model utility of application number 201020290202.1 all relates to a kind of securing means with the screw screw rod, but these technology all have narrow limitation: the both sides of working surface all need the space of enough operations in practical operation, as being when the securing means of band screw screw rod is set on the aperture of enclosed space in a side; Because the external diameter of screw can not be put into greater than the aperture of aperture, this securing means just can not be satisfied the demand.
Summary of the invention
The technical problem that the utility model will solve is the present situation to existing technology, provides a kind of simple and reasonable, makes easy for installationly, is applicable to a kind of securing means with the screw screw rod that the operating space is special.
The technological scheme that the utility model addresses the above problem is: a kind of securing means with the screw screw rod; Comprise screw rod, the screw with screw rod is complementary flexibly connects a brake slipper on the screw rod; Brake slipper is expansion shape brake screw with screw rod in order to when placing screw rod, to depend on screw rod when fastening.When the screw rod of the utility model is placed into a side and is the aperture of enclosed space; Make brake slipper depend on screw rod with hand; The external diameter of screw rod is not obviously increased; Screw rod is expansion shape brake screw at brake slipper and screw rod under the effect of gravity after being placed into aperture smoothly, as long as DRIVE SCREWS can reach fastening purpose.
Preferably; Brake slipper and screw rod are slidingly connected; Brake slipper is a slide block, and slide block has the outside slide block end of protrusion, and vertical its body of rod is provided with the semiclosed slideway that is complementary with slide block on the screw rod; Slide block is slidingly connected on the slideway with the mode of slide block end towards the slideway top, and the opening of slideway inwardly shrinks in case the limited slip block end skids off.Slide block and screw rod are slidingly connected and make screw rod be placed into aperture smoothly like this, are placed into behind the aperture to skid off screw rod at the effect bottom slide block from gravity and be and launch the shape brake screw.
Preferably, brake slipper and screw rod are rotationally connected, and brake slipper is a switch block, and two ends of switch block exceeded the body of rod of screw rod respectively when switch block and screw rod were the expansion shape.Switch block and screw rod are rotationally connected and make screw rod be placed into aperture smoothly like this, are placed into behind the aperture to produce screw rod at switch block under the effect of gravity and be and launch the shape brake screw.
In fact, brake slipper and screw rod also have multiple Placement, adopt elasticity to be connected like brake slipper and screw rod; It is also not necessarily vertical each other when brake slipper is slidingly connected with screw rod; And for example an end rotating hinge of brake slipper is connected on the screw rod, and screw rod is provided with the backer that the restriction brake slipper forwards scope to.
Further technology has the groove that is complementary with switch block, in the switch block insertion groove on the screw rod.Such setting makes switch block depend on screw rod better.
Technology further, the tie point of screw rod and brake slipper is at an end of screw rod.Clearly the screw rod after the tie point of screw rod and brake slipper is useless, can omit.
Technology further, said screw rod do not have the regular shape that is complementary with spanner in order to an end that inserts working surface.When DRIVE SCREWS, need standing screw, as being provided with not having needs with the vice standing screw inconvenient.
Compared with prior art, the utility model is a kind of securing means with the screw screw rod, flexibly connects a brake slipper on the screw rod.The utlity model has following advantage: advantages of simple, make easy for installationly, be applicable to the working environment that the operating space is special.

Embodiment
Below in conjunction with embodiment the utility model is described in further detail:
A kind of securing means with the screw screw rod comprises screw rod 1, and the screw 2 that is complementary with screw rod 1 flexibly connects a brake slipper on the screw rod 1, and brake slipper is the expansion shape with screw rod 1 and brakes said screw rod 1 in order to when placing screw rod 1, to depend on screw rod 1 when fastening.
Wherein, Brake slipper and screw rod 1 are slidingly connected; Brake slipper is a slide block A, and slide block A has the outside slide block end A1 of protrusion, and vertical its body of rod is provided with the semiclosed slideway B that is complementary with slide block A on the screw rod 1; Slide block A is slidingly connected on the slideway B with the mode of slide block end A1 towards slideway B top, and the opening B1 of slideway B inwardly shrinks in case limited slip block end A1 skids off.
The utility model is achieved in that using hand to make slide block A depend on screw rod 1 inserts the aperture X of a side as enclosed space; Screw rod 1 is placed into smoothly behind the aperture X and skids off screw rod 1 at the effect bottom slide block A from gravity and be and launch the shape brake screw, as long as DRIVE SCREWS 2 can reach fastening purpose.
A kind of securing means with the screw screw rod comprises screw rod 1, and the screw 2 that is complementary with screw rod 1 flexibly connects a brake slipper on the screw rod 1, and brake slipper is the expansion shape with screw rod 1 and brakes said screw rod 1 in order to when placing screw rod 1, to depend on screw rod 1 when fastening.
Wherein, brake slipper and screw rod 1 are rotationally connected, and brake slipper is a switch block D, and two ends of switch block D exceeded the body of rod of screw rod 1 respectively when switch block D and screw rod 1 were the expansion shape.
Wherein, have the groove K that is complementary with switch block D on the screw rod 1, in the switch block D insertion groove K.
Wherein, the tie point of screw rod 1 and switch block D is at an end of screw rod 1.
