Abstract
Ratchet wheel for binding device belongs to mechanical technique field and solves problem for weak mechanical intensity of reel in existing device. It comprises wheel body with ratchet around body outside and two axis holes in body for reel passing; there is supporting bar between holes fixed on and bumped toward wheel body; when assembling ratchet wheel, make the supporting bar toward inside to shorten their distance and then increase reel mechanical intensity. It just needs to change ratchet wheel shape to achieve purpose; meantime, increases cost little; however, it improves blinding device performance marked, safe and reliable, and has high use value.
Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of binding tools, particularly a kind of instrument that is used for Goods binding on the haulage vehicle.
Background technology
In automobile carried cargo process, goods needed binding usually.Adopt common nylon rope or steel wire rope to bundle that not only efficient is low, and operation effort very; Simultaneously, also be difficult to goods is bound.Bundled device can be quickly and easily with the Goods binding location, so be used widely at present.
As Figure 13 and shown in Figure 14, existing bundled device is made up of parts such as body 8, ratchet 1, baffle plate 9, spring 10, handle 5, spool 3, lateral piece 4, ribbon 6 and buckles 7.Make ratchet 1 one-directional rotation by pulling lateral piece 4, the ribbon of rolling up on spool 36 is constantly tightened up, make buckle 7 tensions of two hooks on goods or car body.
In the bundled device of existing structure, spool 3 is approximately semicircular woodruff key 31 by two cross sectional shapes and is formed.Ratchet 1 is passed at the two ends of these two woodruff keys 31 respectively, and is fixed together by pin 32.
When vehicle delivers heavier goods, need bigger seizing force.This mechanical strength to bundled device is a test.In fact, when restraint of loads, tighten up belt Overexertion, bundled device is damaged.And what be damaged at first in the bundled device is two woodruff key 31 flexural deformations of spool 3, as shown in figure 14.
Therefore, if improve the resistance to deformation intensity at spool 3 places, just can improve the mechanical strength of bundled device most effectively.
To this, adopt some common way poor effect.Strengthen as size,, can increase the cost of product though can improve mechanical strength with spool; And, in the product of same specification,, joining part such as ratchet is diminished if the size of spool strengthens, influence other part machinery intensity conversely.
Summary of the invention
The objective of the invention is problem at the bad mechanical strength at the existing present existing spool of bundled device place, a kind of ratchet of bundled device of novel structure is provided, by improvement to ratchet structure, the resistance to deformation intensity at bundled device spool place is improved, thereby the mechanical strength of whole bundled device is improved; Simultaneously, of the present invention simple and reasonable, implement easy, safe and reliable.
Purpose of the present invention can realize by following technical proposal: the ratchet of this bundled device comprises wheel body, outer at wheel body is provided with ratchet, two axis holes that supply spool to pass are arranged in wheel body, between these two axis holes, a support bar is arranged, it is characterized in that, described support bar protrudes to a side of wheel body, and support bar and wheel body are connected.Spool is made up of two woodruff keys.After the spool assembling, the support bar of its ratchet just is stuck between these two woodruff keys, plays a supporting role.When the bundled device restraint of loads, the tightening force on the ribbon can act on the woodruff key.As shown in figure 14, if tightening force is excessive, can make the woodruff key distortion.Obviously, after the support bar between two woodruff keys is apart from shortening, the tightening force of woodruff key distortion can be increased.Therefore, the present invention utilizes this principle exactly, and support bar in the ratchet is protruded to a side of wheel body.In assembling during ratchet, the support bar that makes two ratchets in the bundled device all inwards, thereby shortened the spacing of two support bars, also just improved the mechanical strength of spool.
Connected mode between support bar and the wheel body can have multiple.As described support bar and wheel body fuse, by punch forming.
And for example, described support bar is fixed on the wheel body by rivet or bolt.
For another example, described support bar is on the welding wheel body.
In addition, described support bar is wrapped on the wheel body by a sheet metal.
Compared with prior art, the invention has the advantages that the alteration of form that only makes ratchet, and other part of bundled device resistance to deformation intensity that just can make spool that remains unchanged improves, and has also just improved the mechanical strength of bundled device.Simultaneously, compare with common ratchet, ratchet product cost of the present invention improves very little, but it is remarkable to improve the impact of performance of bundled device, and safe and reliable, has higher utility.

The specific embodiment
As shown in figure 12, bundled device normally is made up of parts such as body 8, ratchet 1, baffle plate 9, spring 10, handle 5, spool 3, lateral piece 4, ribbon 6 and buckles 7.Ribbon 6 is rolled up on spool 3, and the end of ribbon 6 is a buckle 7.The buckle 7 at bundled device two ends hook in use makes ratchet 1 one-directional rotation by pulling lateral piece 4 repeatedly on goods or car body, ribbon 6 is constantly rolled up on spool 3, and ribbon 6 is tightened up.At last goods is bound the location.
In the present invention, other structure of bundled device is identical with common bundled device, and difference is the improvement to ratchet 1.As shown in Figure 1, the ratchet 1 of bundled device comprises wheel body 11, is provided with ratchet 12 in the outer of wheel body 11, and two axis holes 13 that supply spool to pass are arranged in wheel body 11.
As shown in figure 12, ratchet 12 cooperates with baffle plate 9, makes ratchet 1 one-directional rotation.The spool 3 of bundled device is made up of two woodruff keys 31.These two woodruff keys 31 insert respectively in the above-mentioned axis hole 13, and are fixed together by pin 32 in its outer end.
In ratchet 1, a support bar 2 is arranged between two axis holes 13.Spacing between the support bar 2 will have influence on the resistance to deformation intensity of spool 3.The present invention is by shortening the mechanical strength that two spacings between the support bar 2 improve spool 3.
As depicted in figs. 1 and 2, support bar 2 is connected as a single entity with wheel body 1 among the embodiment one, directly by punch forming.This mode simple structure, production technology is simple, is a kind of practical mode.
As shown in Figure 3 and Figure 4, support bar 2 is to be fixed on the wheel body 11 by rivet 14 among the embodiment two.This structure is connected firmly, and makes support bar 2 bigger with respect to the protrusion distance of wheel body 11.
As shown in Figure 5 and Figure 6, support bar 2 is fixed on the wheel body 11 by bolt 15 among the embodiment three.Compare with the above embodiments, equipment used when ratchet 1 is produced in the present embodiment is minimum, after support bar 2 and wheel body 11 create, directly gets final product with bolt 15 connections.
As shown in Figure 7 and Figure 8, support bar 2 is to be solidly connected together by the mode of welding with wheel body 11 among the embodiment four.This mode structure is also simpler and easy, and being connected firmly between the two, also is a kind of practical mode.
As Fig. 9, Figure 10 and shown in Figure 11, in embodiment five, support bar 2 is wrapped in the wheel body 11 by a sheet metal 16.The production of this mode also is easy to, and makes the distance of support bar 2 protrusion wheel bodys 11 bigger.
In a word, adopt ratchet 1 provided by the invention after, the hypotelorism of the support bar 2 between two ratchets 1, thus improved the resistance to deformation intensity of spool 3, also just improved the mechanical strength of bundled device.
