The invention discloses an automatic tightening device. The tightening device comprises a main body, wherein both ends of the main body are provided with a through hole; a central shaft is arranged in the middle of the main body and is positioned between the through holes at the two ends of the main body; a shaft hole is formed at the lower end of the central shaft; the lower end of the central shaft passes through the main body, and the shaft hole is positioned on the outer side of the main body; and a spring is arranged between the upper end of the central shaft and the main body. The tightening device has a simple structure and attractive appearance, is convenient to use, corrosion-proof, environment-friendly and durable, and is used for automatically tightening tent ropes.
Description
Technical field
The present invention relates to a kind of tightener, specifically a kind of automatic tightener that is applicable to that the tent rope tightens up automatically.
Background technology
Tent is known by users, and tent of a great variety is mainly used in field work, tourism, the anti-dangerous disaster relief, military etc., and tent mainly is made up of tent supporting frame and paulin body, and wherein tent supporting frame and paulin are installed as a minute body structure at the scene.At first bracing frame is fixed during installation, outside bracing frame, laid the paulin body then, through the tent rope paulin body is tightened up then, accomplish setting up of whole tent.When tightening up operation, what camping tent used at present is wooden tightener, uses inconvenience, and fracture easily.
Summary of the invention
In order to overcome the problem that existing wooden tightener exists, the purpose of this invention is to provide a kind of automatic tightener, this tightener is simple in structure, easy to use, anticorrosive, environmental protection, durable, good looking appearance, and generalization is extremely strong.
The objective of the invention is to realize through following technical scheme:
A kind of automatic tightener is characterized in that: this tightener comprises main body, is equipped with through hole at the main body two ends, is provided with central axis at the main body middle part, and central axis is between the through hole of two ends; Lower end at central axis is provided with axis hole, and the lower end of central axis passes main body and axis hole is positioned at the main body outside; Between the upper end of central axis and main body, be provided with spring.
Among the present invention, for easy to adjust, central axis is arranged on the centre position between the through hole of two ends.The both side ends of main body is an arcwall face, and it is more comfortable to let the user hold automatic tightener.The through hole at two ends and axis hole are all suitable with the diameter of cinch cord.
Compared with prior art, the present invention is simple in structure, easy to use, anticorrosive, environmental protection, durable, good looking appearance, and generalization is extremely strong.The present invention is used for the tent rope and tightens up automatically.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a user mode schematic cross-section of the present invention.
The specific embodiment
A kind of automatic tightener of the present invention is seen Fig. 1, and this tightener comprises main body 1, and the both side ends of main body 1 is an arcwall face, and it is more comfortable to let the user hold automatic tightener.Be respectively equipped with the through hole 2 that is used for wearing tent rope 5 in main body 1 right ends, the through hole 2 at two ends is suitable with the diameter of cinch cord.Be provided with central axis 3 at main body 1 middle part, for easy to adjust, the centre position of central axis 3 between two ends through hole 2.Also be provided with the axis hole 31 that is used for wearing the tent rope in the lower end of central axis 3, axis hole 31 is suitable with the diameter of cinch cord.The lower end of central axis 3 passes main body 1 and axis hole 31 is positioned at main body 1 outside; Between the upper end of central axis 3 and main body 1, be provided with spring 4.Central axis 3 is a stud mounted construction, and spring 4 is arranged between nuts and the main body 1.Main body 1 can be selected polyformaldehyde material for use.
Fig. 2 is a user mode schematic cross-section of the present invention.During use, rope 5 is penetrated in an end through hole 2 of automatic tightener main body 1, press central axis 3 downwards with hand simultaneously; Rope 5 is penetrated in the axis hole 31 of central axis, again rope 5 is penetrated in the other end through hole 2 of main body 1 at this moment openhanded opening; Under spring 4 effects, central axis 3 pops up, and the axis hole 31 of wearing rope 5 retracts in the main body 1; Realize auto-lock function, rope 5 can not move.When needing the adjusting rope long and short, pin automatic tightener central axis 3 downwards, but easy adjustment.
The present invention is simple in structure, easy to use, and when being used to tighten up operation, adjustment freely; And anticorrosive, environmental protection, durable, good looking appearance.
