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.

In the description of the present invention, it is to be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

In the present invention, unless otherwise expressly stated or limited, the terms "disposed," "mounted," "connected," and "fixed" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection; may be a mechanical connection; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Examples

As shown in fig. 1, a safe convenient mould changing device, including slider 1, slider below fixedly connected with bracket, the bracket comprises two parallel arrangement's slide rail 2, sliding connection has tray 3 between two slide rails, the tray can move in and out on two slide rails, be equipped with in the tray and connect in the hole 5 of placing of ring flange 4 assorted on jumper bar top, combine shown in fig. 4, during the use, the jumper bar that will change is put in placing in the hole 5 can, need not artifical the jumper bar of holding, the intensity of labour has been reduced, it has gyro wheel 6 to rotate on the slide rail to be connected, the outer peripheral face and the tray contact of gyro wheel are connected, help reducing frictional force, the removal on the slide rail again of the tray of being convenient for.

As shown in fig. 2, the sliding rail is composed of a fixed arm 201 and a movable arm 202, the fixed arm is fixedly connected with the sliding block, the movable arm is hinged to the fixed arm through a pin 203, the movable arm and the fixed arm can be freely folded to reduce occupied space, a limiting rod 10 is arranged at one end of the movable arm far away from the fixed arm, the tray can be prevented from derailing, and potential safety hazards are eliminated. It is shown in combination with fig. 3 that fixed arm and digging arm are by first curb plate 7, second curb plate 8 and connecting rod 9 are constituteed, first curb plate and second curb plate parallel arrangement just are connected through a plurality of connecting rod, the second curb plate is located one side that first curb plate is close to the tray, the gyro wheel rotates and installs on the connecting rod, first curb plate, the up end height of gyro wheel and second curb plate reduces in proper order, the tray bears the pressure on the gyro wheel of two slide rails completely, the gyro wheel is installed between first curb plate and second curb plate, can strengthen the stability and the bearing capacity of bracket.
