FIG. 2 is a schematic view of a card slot structure;

fig. 3 is a schematic view of the locking state of the present invention.

In the figure: 1. a cylinder; 2. a connecting rod; 3. a support; 4. fastening a bolt; 5. a positioning member; 6. a rubber head; 7. a clamping groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model discloses a cylinder, connecting rod, support, trip, setting element, rubber head and draw-in groove have adopted the cylinder to connect the connecting rod, drive the trip and accomplish transverse motion, realize the effect to mechanical device safety locking. The cylinder is adopted to drive the clamping bolt, so that the safety performance of the clamping bolt is improved, the application range is wide, and the clamping bolt is suitable for various mechanical devices.

As shown in fig. 1 the utility model discloses overall structure schematic diagram, a pneumatic type safety catch device include cylinder 1, connecting rod 2, support 3, bayonet catch 4, setting element 5, rubber head 6 and draw-in groove 7, 2 one ends of connecting rod are connected cylinder 1 telescopic links, and one end is connected bayonet catch 4, and the centre is provided with support 3, be provided with setting element 5 in the middle of the bayonet catch 4, 4 tops of bayonet catch set up rubber head 6, and rubber head 6 establishes to the semicircle head, and the button head is favorable to bayonet catch 4 can not take place the phenomenon that the edge blocked when passing draw-in groove 7.

The connecting structure is a connecting rod 2, kinematic pairs in the connecting rod mechanism are all low pairs, two components forming the motion are in surface contact, so that the borne pressure is small, the lubrication is convenient, the abrasion is light, the large load can be borne, the impact resistance is realized, the components are simple, the geometric shape is convenient for plane processing, if the clamping bolt 2 is directly and vertically connected onto a cylinder rod of the cylinder 1, the stress of the clamping bolt 4 can be caused to be uneven, and the transverse motion can be unstable and the abrasion to the clamping bolt 2 is large due to the direct driving of the cylinder.

As shown in fig. 2, the card slot 7 is configured in a circular connecting rectangle shape.

When the cylinder rod of the cylinder 1 shown in fig. 1 extends out, the clamping bolt 4 is inserted into the clamping groove 7 through the connecting rod 2, the clamping groove 7 touches the positioning part 5, the positioning part 5 generates current change and feeds back the current change to the control system, the cylinder rod of the cylinder 1 begins to contract to drive the clamping bolt 4 to transversely move in the clamping groove to complete locking action, and finally the state shown in fig. 3 is achieved.

The clamping groove 7 is provided with a base, and symmetrical fixing through holes are formed in the base and can be fixed on mechanical equipment needing to use the safety clamping bolt device through bolt connection.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
