Abstract
The utility model relates to a height-adjustable pull rod which comprises a base, a main rod, a secondary rod, a handle and a supporting rod, wherein the main rod is arranged on the base; the secondary rod is movably connected with the main rod; the handle is connected with the front end of the secondary rod; the supporting rod is connected with the handle; the height-adjustable pull rod further comprises two shafts arranged between the main rod and the secondary rod; a moving block is arranged at the tail end of the secondary rod; a rotational stopping piece is arranged in the moving block; the two shafts penetrate through two sides of the stopping pieces; the lower part of the middle of the stopping piece is propped against the spring; and the upper part of the middle of the stopping piece is propped against the supporting rod. When an inclined angle is formed between the stopping piece and a shaft by using the spring, the moving block is clamped to stopping moving; and when the stopping piece is pushed by the supporting rod to be vertical to the shaft, the moving block can vertically slide, so that the length of the pull rod can be freely adjusted. The height-adjustable pull rod is convenient to use and has a simple structure.
Description
Technical field
The utility model relates to a kind of adjustable height pull bar.
Background technology
The vigorous of general mood owing to travel in recent years makes suitcase and auxiliary product thereof also attract attention greatly jointly, even becomes the target that manufacturer the most actively researches and develops.And now on the market the most common to promptly be the suitcase of scalable pull 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
But the technical problems to be solved in the utility model provides a kind of length regulated at will, and easy to use, adjustable height pull bar simple in structure.The utility model is achieved through the following technical solutions:
A kind of adjustable height pull bar of the present utility model comprises base, and is arranged on the female bar on the base, reaches the sub bar that flexibly connects 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 two axles that are arranged between female bar and the sub bar, the end of described sub bar is provided with movable block, be provided with rotating locking plate in the described movable block, described diaxon runs through the both sides of locking plate, the middle lower portion position of described locking plate has supported spring, the middle upper portion position of described locking plate with support bar and connect.
As improvement, the both sides of described locking plate are provided with through hole, and the diameter of described through hole is greater than the diameter of axle.
As improvement, described handle is provided with the button that promotes to support bar.
Adjustable height pull bar of the present utility model because described axle runs through the both sides of locking plate simultaneously, the middle lower portion position of described locking plate has supported spring, the middle upper portion position of described locking plate with support bar and connect.When make locking plate and axle when the oblique angle is arranged by spring, movable block blocks motionless, and when with supporting bar promotion locking plate when square with the axis, movable block can slide up and down, thereby reaches the length of adjusting yoke arbitrarily, and it is easy to use, and is simple in structure.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the stereogram of the utility model adjustable height pull bar;
Fig. 2 is the schematic diagram that female bar cooperates with sub bar in the utility model adjustable height pull bar.
The specific embodiment
See also Fig. 1 to shown in Figure 2, a kind of adjustable height pull bar of the present utility model comprises base 1, and is arranged on the female bar 2 on the base 1, and the sub bar 3 that flexibly connects 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 two axles 7 that are arranged between female bar 2 and the sub bar 3, the end of described sub bar 3 is provided with movable block 8, be provided with rotating locking plate 80 in the described movable block 8, described diaxon 7 runs through the both sides of locking plate 80, the middle lower portion position of described locking plate 80 has supported spring 81, the middle upper portion position of described locking plate 80 with support bar 6 and connect.The both sides of described locking plate 80 are provided with through hole (not shown), and the diameter of described through hole is greater than the diameter of axle 7.When making locking plate 80 with axle 7 oblique angle be arranged by spring 81, movable block 8 blocks motionless, and when promoting locking plates 80 when vertical with spools 7 with supporting bar 6, movable block 8 can slide up and down, thereby reaches the length of adjusting yoke arbitrarily, and it is easy to use, and is simple in structure.
Wherein, described handle 4 is provided with the button 40 that promotes to support bar 6, supports bar 6 and supports locking plate 80, thereby realize a locking plate 80 and 7 holds.
Adjustable height pull bar of the present utility model because described axle runs through the both sides of locking plate simultaneously, the middle lower portion position of described locking plate has supported spring, the middle upper portion position of described locking plate with support bar and connect.When make locking plate and axle when the oblique angle is arranged by spring, movable block blocks motionless, and when with supporting bar promotion locking plate when square with the axis, movable block can slide up and down, thereby reaches the length of adjusting yoke arbitrarily, and it is easy to use, and is simple in structure.
The foregoing description; it is an example of the present utility model; be not to be used for limiting enforcement of the present utility model and interest field; all equivalences of being done according to the described process for making of the utility model patent protection scope change and modify, and all should be included in the utility model claim.
