Abstract

The invention discloses a tensioner which comprises a shell and a pull rope, wherein a rope outlet is arranged on the shell. The tensioner is characterized in that a sucking disc is arranged below the shell; a ratchet wheel and a pawl are arranged in the shell; the ratchet wheel is connected with a return knob; the return knob is arranged outside the shell; one end of the pawl is matched with the ratchet wheel, while the other end of the pawl is arranged outside the shell; and the pull rope is wound on the ratchet wheel. The tensioner is fixed on a car trunk by using the sucking disc, and then the pull rope is pulled out of the shell to fixedly bind the trunk. The tensioner is convenient to use, is convenient for a user to bind the trunk and brings convenience to the traffic safety; and with the adoption of the tensioner, the problem of difficult close of the trunk in the background art is solved.

Description

A kind of strainer

Technical field

What the present invention relates to is a kind of invention of strainer, particularly be a kind of strainer that automobile trunk is used that bundlees.

Background technology

The automobile trunk space is limited, and when placing the article of big volume, the boot case lid just is difficult to close sometimes, and this moment, the user tended to boot is pinioned with rope, avoided article in the process of transporting, in boot, to drop out.But be not exclusively used in the apparatus that the binding automobile trunk is used at present, the user not only is difficult to find suitable rope when binding, and when binding, because boot does not have position point, thereby depends merely on very inconvenience of rope binding.

Summary of the invention

In view of the existing technical matters of background technology, technical matters to be solved by this invention provides a kind of strainer that is exclusively used in the binding automobile boot, the convenient use.

In order to solve the problems of the technologies described above, the present invention adopts following technical scheme to realize: this kind strainer includes housing and stay cord; Said housing is provided with rope outlet, it is characterized in that the below of said housing is provided with sucker, is provided with ratchet and pawl in the said housing; Said ratchet is connected with the knob that resets, and the said knob that resets is arranged on outside the housing, and an end and the ratchet of said ratchet are complementary; The other end of said ratchet places outside the housing, and said stay cord winding is on ratchet.

The center of said sucker is provided with bolt, and said bolt passes housing and is threaded with the briquetting of housing top.

The present invention is fixed on strainer on the automobile trunk with sucker, then stay cord is pulled out in the housing boot binding is firmly got final product.When stay cord, an end that places the outer ratchet of housing is pinned, make the other end of ratchet break away from ratchet, ratchet can freely rotate, and spur stay cord and just can pull it until required length this moment.The present invention is easy to use, is convenient to the user and bundlees boot, has solved the problem that the boot that occurs in the background technology is difficult to close, and has brought facility to traffic safety.

Description of drawings

Further describe concrete structure of the present invention and principle of work thereof below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present invention.

Fig. 2 is the structural representation of ratchet of the present invention and ratchet.

The specific embodiment

With reference to accompanying drawing, this kind strainer includes housing 4 and stay cord; Said housing 4 is provided with rope outlet 8; The below of said housing 4 is provided with sucker 3, and the center of said sucker 3 is provided with bolt 1, and said bolt 1 passes housing 4 and is threaded with the briquetting 5 of housing top.Be provided with ratchet 2 and ratchet 7 in the said housing 4; Said ratchet 2 is connected with the knob 6 that resets, and the said knob 6 that resets is arranged on outside the housing 4, and an end and the ratchet 2 of said ratchet 7 are complementary; The other end of said ratchet 7 places outside the housing 4, and said stay cord winding is on ratchet 2.

When the present invention uses, sucker 3 by being pressed in car surface, is made the air emptying in the sucker 3, sucker 3 like this just car surface fits tightly, and is adsorbed on car surface firmly; Also can be with sucker 3 by being pressed in car surface, briquetting 5 is threaded rotation briquetting 5 with bolt 1 on the sucker; Because of stopping of housing; Can force bolt 1 along moving on the briquetting, make that promptly the center of sucker 3 is upwards mentioned, and the periphery of sucker 3 fitted with car surface still; So make sucker 3 air pressure outward greater than the pressure in the sucker, thereby make sucker 3 be adsorbed on car surface firmly.After sucker 3 fixing the completion, then push ratchet 8, make the other end of ratchet 8 break away from ratchet 2; Ratchet 2 is in free state, and spur stay cord this moment, and ratchet 2 clockwise rotates; Until Len req, then decontrol ratchet 8, ratchet 8 resets and ratchet 2 engagements; This moment, ratchet 2 was in locking state, and pulling rope length also is locked, and the user can carry out binding work; After the use, rotate counterclockwise the knob 6 that resets, ratchet 2 rotates counterclockwise under external force, and stay cord is resetted, and is returned in the housing 4.
