Abstract
The invention discloses a pull rod, comprising a base, a master rod arranged on the base, a slavery rod movably connected with the master rod, a handle connected with the front end of the slavery rod, a butting rod connected with the handle, and a shaft penetrating the master rod and the slavery rod, the tail end of the slavery rod is provided with a movable block, two rotatable locking plates are oppositely arranged in the movable block, a spring is arranged between the two locking plates, the shaft simultaneously penetrates the movable block and locking plates, one locking plate is provided with a pushing block which cooperates with the butting rod and is used for pushing the locking plate, and the other locking plate abuts against the butting rod. According to the invention, when the spring allows the locking plates and shaft to form an oblique angle, the movable block gets stuck to be not moved; when the butting rod pushes the locking plates to be vertical to the shaft, the up-down sliding movement of the movable block can be realized, and the length of the pull rod can be adjusted at will. The pull rod has the advantages of convenient usage and simple structure.
Description
Technical field
The present invention relates to a kind of pull bar.
Background technology
The vigorous of general mood owing to travel in recent years makes jointly suitcase and auxiliary product thereof also attract attention greatly, even becomes the target that manufacturer the most actively researches and develops.And now on the market the most common to namely be the suitcase of telescopic bar length, utilize the son of suitcase upper connecting rod, female pipe box to close so that the length of pull bar can be adjusted, with reduce palpus the application of force and draw difference on the line height.Yet existing pull bar can only have two length to regulate when adjusting length, i.e. and minimum length the highest, and it is regulated length and fixes, and can not arbitrarily adjust its length according to user's needs, the use inconvenience.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of length and can arbitrarily regulate, and easy to use, pull bar simple in structure.The present invention is achieved through the following technical solutions:
A kind of pull bar of the present invention comprises base, and is arranged on the female bar on the base, reaches the sub bar that is flexibly connected with female bar, and the handle that links to each other with the sub bar front end, reaches the bar that supports that links to each other with handle; Also comprise the axle that runs through described female bar and sub bar, the end of described sub bar is provided with movable block, be provided with two locking plates rotating, that be oppositely arranged in the described movable block, be provided with spring between described two locking plates, described axle runs through movable block and locking plate simultaneously; Be provided with and support pushing block that bar matches, that be used for to promote this locking plate on the described locking plate, described another locking plate with support bar and connect.
As improvement, be provided with through hole on the described locking plate, the diameter of described through hole is greater than the diameter of axle.
As improvement, be provided with the button that promotes to support bar on the described handle.
As improvement, between described two locking plates, be provided with locating dowel in the position at two ends, described pushing block is installed in wherein on the locating dowel.
Pull bar of the present invention, owing to be provided with and support pushing block that bar matches, that be used for this locking plate of promotion on the described locking plate, described another locking plate with support bar and connect, when making locking plate and axle that the oblique angle is arranged by spring, movable block blocks motionless, when promoting locking plate when square with the axis with supporting bar, movable block can slide up and down, thereby reach the arbitrarily length of adjusting yoke, it is easy to use, and is simple in structure.
Description of drawings
In order to be easy to explanation, the present invention is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the stereogram of pull bar of the present invention;
Fig. 2 is the schematic diagram that female bar cooperates with sub bar in the pull bar of the present invention.
The specific embodiment
See also Fig. 1 to shown in Figure 2, a kind of pull bar of the present invention comprises base 1, and is arranged on the female bar 2 on the base 1, and the sub bar 3 that is flexibly connected with female bar 2, and the handle 4 that links to each other with sub bar 3, reach link to each other with handle 4 support bar 6; Also comprise the axle 7 that runs through described female bar 2 and sub bar 3, the end of described sub bar 3 is provided with movable block 8, be provided with two locking plates 80 rotating, that be oppositely arranged in the described movable block 8, be provided with spring 9 between described two locking plates 80, described axle 7 runs through movable block 8 and locking plate 80 simultaneously; Be provided with on the described locking plate 80 and support the pushing block 81 that bar is 6 that match, be used for promoting this locking plate 80, described another locking plate 80 with support bar 6 and connect.When making locking plate 80 and axle 7 that the oblique angle is arranged by spring 9, movable block 8 blocks motionless, and when with supporting bar 6 promotion locking plates 80 and axle 7 when vertical, movable block 8 can slide up and down, thereby reaches the arbitrarily length of adjusting yoke, and it is easy to use, and is simple in structure.
Wherein, be provided with the button 40 that promotes to support bar 6 on the described handle 4, support bar 6 and support locking plate 80, thereby realize holding of locking plate 80 and axle 7.Between described two locking plates 80, be provided with locating dowel 82 in the position at two ends, described pushing block 81 is installed in wherein on the locating dowel 82.
Pull bar of the present invention, owing to be provided with and support pushing block that bar matches, that be used for this locking plate of promotion on the described locking plate, described another locking plate with support bar and connect, when making locking plate and axle that the oblique angle is arranged by spring, movable block blocks motionless, when promoting locking plate when square with the axis with supporting bar, movable block can slide up and down, thereby reach the arbitrarily length of adjusting yoke, it is easy to use, and is simple in structure.
Above-described embodiment; it is an example of the present invention; be not to limit enforcement of the present invention and interest field, all equivalences of doing according to the described process for making of the present patent application scope of patent protection change and modify, and all should be included in the present patent application claim.
