In the figure: the device comprises a plate 1, a support tube 2, a fixed disc 3, a supporting block 4, a threaded hole 5, a threaded sheath 6, an opening 7, a bolt 8, a nut 9, an operating handle 10, a holding block 11 and a clamping groove 12.

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.

Referring to fig. 1 to 3, the present invention provides a technical solution: the utility model provides a locking device of extension silo, includes plate 1, plate 1's right side fixedly connected with stay tube 2, and plate 1 and stay tube 2 are self structure of extension silo, the lateral surface fixedly connected with fixed disk 3 of stay tube 2, two supporting shoes 4 of fixed disk 3's last fixed surface fixedly connected with.

The front side and the rear side of the two supporting blocks 4 are both provided with threaded holes 5, the two threaded holes 5 are both in threaded connection with threaded sheaths 6, the opposite sides of the two supporting blocks 4 are both fixedly connected with the supporting tube 2, the front side and the rear side of the two supporting blocks 4 are both penetrated with openings 7, the two supporting blocks 4 are respectively sleeved with bolts 8 through the two openings 7, both sides of each bolt 8 are both in threaded connection with nuts 9, the opposite sides of the two nuts 9 are respectively abutted against the two supporting blocks 4, the bottom surface of each bolt 8 is fixedly connected with an operating handle 10, the right side of the fixed disc 3 is provided with a clamping groove 12, the operating handle 10 is clamped with the clamping groove 12, the operating handle 10 is abutted against the threaded sheaths 6, when the operating handle 10 needs to be locked when the concrete mixer truck works, an operator firstly rotates the threaded sheaths 6, and through the threaded connection relationship between the threaded sheaths 6 and the two supporting blocks 4, the rear end of the threaded, thereby pulling the operating handle 10, and through the fixed connection relationship between the operating handle 10 and the bolt 8, the sleeving relationship between the bolt 8 and the two supporting blocks 4, and the limiting relationship between the two nuts 9, the bolt 8 rotates along the inner wall of the opening 7, so that the operating handle 10 moves to the clamping groove 12 on the left side of the threaded sheath 6, and then the operating personnel reversely rotates the threaded sheath 6, so that the rear end of the threaded sheath 6 is screwed into the threaded hole 5 on the rear side supporting block 4 again, thereby limiting the operating handle 10 in the clamping groove 12, avoiding the random rotation of the operating handle 10 caused by bumping during the working or driving process of the concrete mixer truck, and in the process of rotating the lengthened groove of the concrete mixer truck, similarly, the operating personnel only need to rotate the threaded sheath 6 and pull the operating handle 10, so that the operating handle 10 moves to the right side of the threaded sheath 6, and then reversely rotates the threaded sheath 6, the operating handle 10 can rotate freely, and meanwhile, due to the limiting effect of the thread sheath 6, the operating handle 10 is prevented from falling into the clamping groove 12 due to external force to influence free rotation.

Preferably, the bottom surface of the operating handle 10 is fixedly connected with the holding block 11, and the operating handle 10 is convenient for an operator to rotate by arranging the holding block 11, so that the working efficiency is improved, and the time and labor saving effects are achieved.

The working principle is as follows: when the operation handle 10 of the lengthened trough locking device needs to be locked when the concrete mixer truck works, an operator firstly rotates the threaded sheath 6, the rear end of the threaded sheath 6 is screwed out of the supporting block 4 positioned on the rear side and moves to a certain distance through the threaded connection relationship between the threaded sheath 6 and the two supporting blocks 4, so that the operation handle 10 is pulled, the bolt 8 rotates along the inner wall of the opening 7 through the fixed connection relationship between the operation handle 10 and the bolt 8, the sleeving relationship between the bolt 8 and the two supporting blocks 4 and the limiting relationship between the two nuts 9, so that the operation handle 10 moves to the clamping groove 12 on the left side of the threaded sheath 6, then the operator reversely rotates the threaded sheath 6, so that the rear end of the threaded sheath 6 is screwed into the threaded hole 5 positioned on the rear side supporting block 4 again, the operation handle 10 is limited in the clamping groove 12, and the operation handle 10 is prevented from rotating due to bumping randomly in the working or driving process of the concrete mixer truck, at the concrete mixing transport vechicle at rotatory elongated groove in-process that adds, on the same principle, operating personnel only need rotate screw thread sheath 6 and pulling operating handle 10 for operating handle 10 moves to the right side of screw thread sheath 6, then counter-rotation screw thread sheath 6 can make operating handle 10 can the free rotation, because the limiting displacement of screw thread sheath 6 has simultaneously avoided operating handle 10 to influence the free rotation because external force drops to draw-in groove 12 in.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
