Technical field
The utility model relates to support rod equipment technical fields, more particularly, to a kind of support rod.
Background technique
Support rod is mainly made of piston, piston rod and the valve rod etc. in cylinder barrel, cylinder barrel, and storage has gas or storage in cylinder barrel
There is gas mixture.Since piston has occupied the volume in cylinder barrel, so it is less than the cross of piston using the cross-sectional area of piston rod
Sectional area realizes the movement of piston rod to the pressure difference generated.Existing support rod is unable to control due to stretching out speed, or
The power acted on piston rod when contraction is excessive, collides so as to cause between piston or piston rod and cylinder body, and causes
Inner body impact can reduce the service life of support rod so that inner components are damaged for a long time.
Utility model content
The technical problems to be solved in the utility model is:It is unable to control to solve existing support rod due to stretching out speed,
Or the power acted on piston rod when shrinking is excessive, asks so as to cause what is collided between piston or piston rod and cylinder body
Topic, now provides a kind of support rod.
Technical solution adopted by the utility model to solve its technical problems is:A kind of support rod, including with piston rod
The first cylinder, further include extension bar, piston, the second cylinder, spring and slide, the piston is slidably arranged in second cylinder,
One end of the extension bar is arranged on the piston, other end stretching second cylinder of the extension bar, in the slide
Offer channel, the extension bar is provided with sliding block far from one end of piston, the sliding block along extension bar radially outwardly projecting simultaneously
The stairstepping shaft shoulder is formed, the channel matches with the sliding block, and the sliding block is slidably arranged in the channel, the spring
It is arranged between the sliding block and the channel, the extension bar passes through the slide, the piston rod far from one end of sliding block
Channel on the slide is simultaneously connect with piston rod thread, and the piston rod is coaxially set with the extension bar, described
One end that second cylinder extends away from bar is provided with screw rod, and the screw rod is coaxially set with the extension bar.It is stretched out in extension bar
When, by buffering between the second cylinder and extension bar and piston, the impact force to the first cylinder of piston rod is reduced, equally when shrinking,
Same slide is contacted with the first cylinder, to squeeze spring, spring plays the role of vibration reduction and cushioning to piston rod.
For the ease of the installation and manufacture of slide, further, the slide includes upper cover and lower seat, the upper cover screw thread
It is connected on the lower seat, offers first through hole on the lower seat, one end of the lower seat is provided with groove, first through hole and recessed
Slot is connected to, and offers the second through-hole on the upper lid.Be combined into slide by upper cover and lower seat, convenient for convenient for slide installation and
Manufacture.
The utility model has the beneficial effects that:The utility model support rod when in use, extension bar stretch out when, by second
Buffered between cylinder and extension bar and piston, reduce the impact force to the first cylinder of piston rod, equally shrink when, same slide with
The contact of first cylinder, to squeeze spring, spring plays the role of vibration reduction and cushioning to piston rod, avoids existing support rod due to stretching out
Speed is unable to control, or the power acted on piston rod when contraction is excessive, collides so as to cause between piston and cylinder body,
And inner body is caused to impact, so that inner components are damaged, the problem of service life of support rod can be reduced for a long time.
Detailed description of the invention

Fig. 2 is the partial enlarged view of A in Fig. 1.
In figure:1, the first cylinder, 2, piston rod, 3, extension bar, 4, piston, the 5, second cylinder, 6, spring, 7, slide, 701, under
Seat, 702, upper cover, 8, channel, 9, sliding block, 10, screw rod,.
Specific embodiment
Presently in connection with attached drawing, the utility model is described in more detail.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
Embodiment
As shown in Figs. 1-2, a kind of support rod, including the first cylinder 1 with piston rod 2, further include extension bar 3, piston 4,
Second cylinder 5, spring 6 and slide 7, the piston 4 are slidably arranged in second cylinder 5, and one end setting of the extension bar 3 exists
On the piston 4, the other end of the extension bar 3 stretches out second cylinder 5, offers channel 8 in the slide 7, described to stretch
Rod 3 is provided with sliding block 9 far from one end of piston 4, and the sliding block 9 is along 3 radially outwardly projecting of extension bar and forms stairstepping axis
Shoulder, the channel 8 match with the sliding block 9, and the sliding block 9 is slidably arranged in the channel 8, and the setting of spring 6 exists
Between the sliding block 9 and the channel 8, the extension bar 3 passes through the slide 7, the piston rod 2 far from one end of sliding block 9
Channel 8 on the slide 7 is simultaneously threadedly coupled with piston rod 2, and the piston rod 2 is set with 3 coaxial line of extension bar
It sets, one end that second cylinder 5 extends away from bar 3 is provided with screw rod 10, and the screw rod 10 is set with 3 coaxial line of extension bar
It sets.Screw rod 10 facilitates support rod 6 can be with the connection between other equipment.Pass through the sliding block 9 of the stairstepping shaft shoulder and leading to for slide 7
Road 8 cooperates, and can limit and slide slide 7, prevent slide 7 from falling extension bar 3
The slide 7 includes upper cover 702 and lower seat 701, and the upper cover 702 is threaded on the lower seat 701, institute
State and offer first through hole on lower seat 701, one end of the lower seat 701 is provided with groove, and first through hole is connected to groove, it is described on
