Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0024] An electric cylinder locking mechanism includes an electric cylinder body 1. A fixed frame 2 is fixedly connected to the outer surface of the electric cylinder body 1. A limiting plate 3 is fixedly connected to the outer surface of the telescopic end of the electric cylinder body 1. Horizontal plates 4 are fixedly connected to both sides of the fixed frame 2. The inside of the horizontal plate 4 is a cavity. A movable connecting plate 5 is slidably connected inside the horizontal plate 4. One end of the movable connecting plate 5 away from the horizontal plate 4 is fixedly connected to the limiting plate 3.

[0025] A guide screw rod 6 is arranged on the outer surface of the horizontal plate 4. The guide screw rod 6 is perpendicular to the horizontal plate 4. A locking slider 7 is slidably connected to the guide screw rod 6. A locking connecting plate 8 is rotatably connected to the locking slider 7. A sliding shaft 9 is fixedly connected to one side of the movable connecting plate 5. One end of the locking connecting plate 8 away from the locking slider 7 is rotatably connected to the sliding shaft 9. A contact sleeve 10 that cooperates with the locking slider 7 is threadedly connected to the guide screw rod 6.

[0026] As Figure 1 , Figure 2 and Figure 4 , the electric cylinder body 1 is a prior art. The fixed frame 2 is fixed on the outer surface of the fixed part of the electric cylinder body 1 to provide support for the electric cylinder body 1. The limiting plate 3 is fixed on the telescopic end of the electric cylinder body 1 and can move together with the telescopic end of the electric cylinder body 1. One end of the movable connecting plate 5 is located inside the horizontal plate 4, which can ensure the horizontal movement of the movable connecting plate 5. The guide screw rod 6 is not directly connected to the fixed frame 2, so that the contact sleeve 10 and the locking slider 7 can move together on the guide screw rod 6. The inner wall of the contact sleeve 10 has threads to achieve threaded connection with the guide screw rod 6.

[0027] A chute 11 is opened on the outer surface of the horizontal plate 4. The sliding shaft 9 is slidably connected to the chute 11.

[0028] AsFigure 1 and Figure 2 One end of the sliding shaft 9 protrudes from the outer surface of the sliding groove 11, so that the sliding shaft 9 can be rotatably connected to the locking connecting plate 8 located outside the transverse plate 4.

[0029] One side of the transverse plate 4 is fixedly connected with a fixing plate 12. One end of the guiding screw 6 is fixedly connected with the fixing plate 12. A limiting ring 13 is fixedly connected to the end of the guiding screw 6 away from the fixing plate 12. Anti-slip grooves are arranged on the outer surface of the abutting sleeve 10.

[0030] As Figure 1 and Figure 2 As shown in FIGS. and, the fixing plate 12 provides support for the guiding screw 6. The limiting ring 13 closes one end of the guiding screw 6 to prevent the locking slider 7 and the abutting sleeve 10 from disengaging from one end of the guiding screw 6. The anti-slip grooves on the abutting sleeve 10 facilitate the manual rotation of the abutting sleeve 10.

[0031] A rectangular groove is formed on the outer surface of the guiding screw 6, and a scale 14 is fixedly installed in the rectangular groove for assisting in reading the position of the abutting sleeve 10.

[0032] As Figure 1 and Figure 2 As shown in FIGS. and, the scale 14 can be used to master the relative position of the abutting sleeve 10 on the guiding screw 6, facilitating the adjustment of the abutting sleeves 10 on both sides of the fixing frame 2 to the same position.

[0033] An assembly card frame 15 is fixedly installed on the top of the fixing frame 2. An assembly card slot 16 is formed on the top of the assembly card frame 15. A rectangular positioning slot 17 is formed at the bottom of the inner wall of the assembly card slot 16, and a plurality of first fixing holes 18 are formed in the rectangular positioning slot 17.

[0034] As Figure 1 As shown in FIG., the assembly card slot 16 of the assembly card frame 15 can be clamped together with an external mechanism. At this time, the first fixing holes 18 can be used to assist in fixing the assembly card frame 15 and the external mechanism.

[0035] A mating groove 19 is formed at the bottom of the fixing frame 2, and a second fixing hole 20 is formed in the inner wall of the mating groove 19.

[0036] As Figure 1 and Figure 3 As shown in FIGS. and, the second fixing hole 20 at the bottom of the fixing frame 2 facilitates the fixing of the bottom of the fixing frame 2 and an external mechanism.

[0037] The working principle of an electric cylinder locking mechanism provided by the present utility model is as follows:

[0038] When the electric cylinder extends, it will drive the limiting plate 3 to move away from the fixed frame 2. The limiting plate 3 pulls the movable connecting plate 5 to move together. The movable connecting plate 5 pulls one end of the locking connecting plate 8 through the sliding shaft 9. The other end of the locking connecting plate 8 pulls the locking slider 7 until the locking slider 7 and the abutting sleeve 10 abut against each other. The locking slider 7 cannot move any further, and both the locking connecting plate 8 and the movable connecting plate 5 cannot move any further, restricting the movement of the limiting plate 3 and realizing the restriction when the electric cylinder body 1 extends to the maximum distance.

[0039] When the abutting sleeve 10 is manually rotated, the abutting sleeve 10 can be made to approach or move away from the locking slider 7. The abutting sleeve 10 moves, and the maximum movement distance of the locking slider 7 on the guiding screw rod 6 will also change correspondingly. Furthermore, the movement distance of the limiting plate 3 is jointly changed through the locking connecting plate 8 and the movable connecting plate 5 to adjust the maximum extension distance of the electric cylinder body 1.

[0040] Compared with the related art, an electric cylinder locking mechanism provided by the present utility model has the following beneficial effects:

[0041] When the electric cylinder body 1 extends, the present utility model can drive the fixed frame 3 to move together, and under the action of the locking connecting plate 8, the locking slider 7 is pulled until the locking slider 7 and the abutting sleeve 10 abut against each other and cannot move any further. At this time, the electric cylinder body 1 cannot extend any further, realizing the rapid locking of the electric cylinder body 1, avoiding the electric cylinder body 1 from malfunctioning and extending excessively, which affects the operation accuracy of the equipment. At the same time, by adjusting the position of the abutting sleeve 10 on the guiding screw rod 6, the sliding distance of the locking slider 7 can be restricted, realizing the restriction of the maximum extension distance of the electric cylinder body 1.

[0042] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
