Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 and 2 show a valve bonnet for a concrete pump truck, which comprises a box body 2 and an upper cover 1. The upper cover 1 is hinged on the box body 2, and the side walls of the upper cover 1 and the box body 2 far away from the hinged position are provided with a positioning mechanism together. The bottom of the box body 2 is provided with a connecting plate, and the connecting plate and the base are fixedly installed through a connecting screw, so that when workers need to maintain the internal electromagnetic valve, the internal electromagnetic valve is maintained or disassembled. The sliding grooves 51 are formed in the side wall of the box body 2 and located above the two connecting plates, and the length direction of the sliding grooves 51 is parallel to the connecting plates. A slide block 52 is arranged in the slide groove 51 in a sliding manner, a shielding flange 5 is fixedly arranged on the slide block 52, and the cross section of the shielding flange 5 is L-shaped and is equal to the side wall of the box body 2.

If fig. 3, a plurality of louvres 23 have been seted up on the circumference lateral wall of box 2, reduce because box 2 receives when insolate, perhaps when the solenoid valve produced the work heat, in time give off the heat to the box 2 outside, reduce the possibility that the high temperature produced the influence to the normal work of solenoid valve. The side wall of the box body 2 at the top of each heat radiation hole 23 is provided with a baffle 231, so that the possibility that concrete slurry splashes into the box body 2 from the heat radiation holes 23 is reduced

As shown in fig. 3 and 4, the side wall of the upper cover 1 facing the box body 2 is fixedly provided with the splicing blocks 11, and the side wall of the box body 2 facing the upper cover 1 is provided with splicing grooves 21 at positions corresponding to the splicing blocks 11. When the upper cover 1 and the box body 2 are closed, the splicing blocks 11 are positioned in the splicing grooves 21. The positioning mechanism comprises positioning blocks 22 of the box body 2 located at two sides of the splicing groove 21 and a locking block 111 on the splicing block 11, and the locking block 111 is located between the two positioning blocks 22. The corresponding positions of the positioning block 22 and the locking block 111 are both coaxially provided with pin holes 4. The two positioning blocks 22 are connected with the lock box 3 in a sliding manner along the horizontal direction, the lock box 3 surrounds the outer sides of the two positioning blocks 22 and the lock block 111, and the top end of the lock box 3 is provided with a slot 32 for inserting the lock block 111. The inner side wall of the lock box 3 is fixedly connected with a pin 31, and the pin 31 is inserted into each pin hole 4, thereby realizing the relative fixation of the upper cover 1 of the box body 2. When the lock box 3 is pushed, so that the slot 32 is away from the upper side of the lock block 111, and the pin 31 is inserted into the pin hole 4, the top wall of the positioning block 22 closes the slot 32, thereby reducing the possibility that concrete grout enters the inside of the lock box 3 from the slot 32 to affect the work of components inside the lock box 3.

As shown in figures 3 and 4, a protective rib 12 is fixedly arranged on the side wall of the upper cover 1 above the box body 2, so that the phenomenon that concrete slurry is polluted on a gap between the upper cover 1 and the box body 2, and the upper cover 1 is adhered to the box body 2 to influence the opening and closing of the upper cover 1 is reduced.

Referring to fig. 4, a handle frame 6 is fixedly disposed on the upper side of the protection rib 12 on the circumferential side wall of the upper cover 1, an inner plate 61 is hinged to the inner side wall of the handle frame 6, a torsion spring (not shown) is disposed at the hinged position of the inner plate 61 and the inner side wall of the handle frame 6, and when the torsion spring is in a natural state, the inner plate 61 is parallel to the plane of the handle frame 6. Be convenient for the staff through the handle to open upper cover 1 to block the concrete thick liquid through setting up inner panel 61, thereby reduce the concrete thick liquid and fill the inboard of handle frame 6, and fill gradually handle frame 6 is inboard, make the staff be difficult to the possibility of grabbing handle frame 6 firmly.

The implementation principle of the embodiment is as follows: through setting up lock box 3 and having reduced the concrete thick liquid and be infected with on positioning mechanism to avoid the concrete that solidifies, influence the condition that upper cover 1 normally opened and close.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
