Description
Technical field
The utility model relates to a kind of cylinders, and in particular to a kind of cylinder with lock.
Background technique
The working principle of cylinder with lock is that the pressure energy of compressed air is converted to mechanical energy, and driving mechanism makees linear reciprocation
Movement, in the terminal of stroke, is lockked piston rod with lock pin, prevents piston from being moved when not ventilating and unlocking by external force
It is dynamic, to guarantee work safety.
And lock pin is all to cause to operate by manual unlocking comparatively laborious, influences working efficiency.
Summary of the invention
To solve the above problems, the purpose of this utility model is to provide a kind of convenient for unlocking and structure are reliably locking
Cylinder.
To achieve the above object, the utility model provides following technical solution: a kind of cylinder with lock, including cylinder body, a left side
End cap, right end cap, piston rod and piston, the piston are placed in the cylinder body, and the piston rod is connected to piston
On, the left end cap is mounted on the left end of the cylinder body, and the right end cap is mounted on the right end of the cylinder body, on the right side
It is additionally provided with air inlet on end cap, the locked groove of annular is equipped on the piston rod, the piston rod is worn from the left end cap
It crosses, solution lock cylinder is installed on the left end cap side wall, the left end cap is equipped with the through-hole for leading to the piston rod,
There is telescopic locking bar, which is inserted into the through-hole in the solution lock cylinder.
The solution lock cylinder further includes unlock cylinder body, unlock piston and locking spring, and the locking bar is mounted on described
It unlocks on piston, the locking spring is arranged between the unlock piston and the bottom of the unlock cylinder body, in the unlock
Unlock connecting hole is additionally provided on cylinder body.
The slotting ring of annular is convexly equipped on the end face of the solution lock cylinder, the aperture position of the through-hole is equipped with to be inserted with described
The groove that ring matches, the slotting ring plug in the groove, and sealing ring is also arranged on the outer wall of the slotting ring, described
Solution lock cylinder is bolted on the left end cover outer wall.
This structure of the utility model is detached from piston rod by the locking bar retraction of solution lock cylinder after solution lock cylinder ventilation
Locked groove unlocks piston rod, locking bar can be pressed into locked groove by the elastic force of locking spring after solving lock cylinder stuffiness, lockup piston
Bar just realizes convenient for unlocking and the reliable technical effect of structure in this way.
The utility model is further described with reference to the accompanying drawings and detailed description.
Detailed description of the invention
Fig. 1 is the perspective view of specific embodiment of the present invention；
Fig. 2 is the cross-sectional view of specific embodiment of the present invention；
Fig. 3 is partial sectional view in specific embodiment of the present invention.
Specific embodiment
The utility model is specifically described below by embodiment, is served only for carrying out the utility model further
Illustrate, should not be understood as the restriction to scope of protection of the utility model.
As shown in Figure 1 and Figure 2, present embodiment discloses a kind of cylinder with lock, including cylinder body 1, left end cap 2, right end cap 3,
Piston rod 4 and piston 42, piston 42 are placed in cylinder body 1, and piston rod 4 connects on the piston 42, and left end cap 2 is mounted on cylinder body 1
Left end, right end cap 3 is mounted on the right end of cylinder body 1, air inlet 31 is additionally provided on right end cap 3, and annular is equipped on piston rod 4
Locked groove 41, piston rod 4 passes through from left end cap 2, and solution lock cylinder 5 is equipped on 2 side wall of left end cap, and left end cap 2 is equipped with logical
To the through-hole 21 of piston rod 4, solving has telescopic locking bar 51 in lock cylinder 5, which is inserted into through-hole 21, unlocks gas
Cylinder 5 further includes unlock cylinder body 53, unlock piston 52 and locking spring 54, and locking bar 51 is mounted on unlock piston 52, locking bullet
Spring 54 is arranged between unlock piston 52 and the bottom for unlocking cylinder body 53, and unlock connecting hole 531 is additionally provided on unlock cylinder body 53,
It is connect by the unlock connecting hole 531 with air pump.
Specifically as shown in figure 3, being convexly equipped with the slotting ring 55 of annular, the aperture position of through-hole 21 on the end face of solution lock cylinder 5
Equipped with the groove 211 to match with slotting ring 55, slotting ring 55 is plugged in groove 211, is also arranged on the outer wall of slotting ring 55 close
Seal 6, solution lock cylinder 5 are fixed on 2 outer wall of left end cap by bolt 7.Such structure can make to solve lock cylinder and left end cap
It is more preferable to connect relatively reliable and air-tightness.
Through the above technical solutions, solution lock cylinder 5, which is bounced back after ventilating by the locking bar 51 of solution lock cylinder 5, is detached from piston rod 4
Locked groove 41, unlock piston rod 4, solve 5 stuffiness of lock cylinder after locking bar 51 can be pressed into locked groove by the elastic force of locking spring 54
In 41, lockup piston bar 4 just realizes convenient for unlocking and the reliable technical effect of structure in this way.
