when the screw 4 pushes the clamping plate 3 to approach the bell and spigot mold body 2, along with the continuous rotation of the screw 4, when the movable block 71 is in contact with the bell and spigot mold body 2, the movable block 71 starts to move towards the inside of the sliding groove due to the blocking of the bell and spigot mold body 2, and meanwhile, the limit strip 72 is limited by the limit groove, so that the movable block 71 can cling to the surface of the bell and spigot mold body 2 to slide downwards under the matching effect of the limit strip 72 and the limit groove, and along with the downward movement of the movable block 71, the telescopic rod 73 and the spring 74 can be gradually compressed, and the bell and spigot mold body 2 can be tightly pressed with the base 1 under the downward friction force of the movable block 71 on the movable block, so that the stability of the bell and spigot mold body 2 during concrete pouring is ensured;

after the movable block 71 completely enters the chute, the two clamp plates 3 can be in contact with the bell and spigot mold body 2, so that the bell and spigot mold body 2 is better fixed under the matching action of the two clamp plates 3 and the movable block 71, and the pouring quality of concrete is improved;

after the pouring is finished, the movable block 71 can be restored to the original position under the action of the spring 74 along with the restoration of the two clamping plates 3.

As shown in fig. 2, the bottom of the movable block 71 is fixedly connected with a bump 8, the sum of the heights of the bump 8 and the movable block 71 is equal to the height of the chute, a U-shaped clamping plate 9 is arranged at the right bottom of the bump 8, the opening of the U-shaped clamping plate 9 is vertically opposite to the bell and spigot mold body 2, and the top of the U-shaped clamping plate 9 is close to the bottom of the clamping plate 3;

when the clamping plate 3 drives the clamping plate 3 to move towards the bell and spigot mold body 2 under the action of the screw 4, the lug 8 can be contained in the chute, when the movable block 71 is in contact with the surface of the bell and spigot mold body 2, along with the continuous rotation of the screw 4, the movable block 71 starts to move towards the chute due to the blocking of the bell and spigot mold body 2, and in the process, the movable block 71 gradually moves downwards under the matching action of the limiting strip 72 and the limiting groove, so that the lug 8 can be clamped into the top opening of the U-shaped clamping plate 9, and the lug 8 can be matched with the U-shaped clamping plate 9 to limit the clamping plate 3 in the front-back direction;

in the in-process of pouring concrete inside bell and spigot mould body 2, when concrete collision bell and spigot mould body 2 made it take place to rock along the fore-and-aft direction, lug 8 can cooperate U-shaped cardboard 9 to make bell and spigot mould body 2 more stable to guarantee the finished product quality after concrete placement.

As shown in fig. 2 and 3, a connecting rod 10 is fixedly connected to one side of the clamping plate 3 close to the screw rod 4, a mounting plate 11 is fixedly connected to the bottom of the connecting rod 10, a roller 12 is mounted at the bottom of the mounting plate 11, the roller 12 is parallel to the side surface of the base 1, and the bottom of the roller 12 is tightly attached to the top of the base 1;

when splint 3 moves along the horizontal direction under the regulation of screw rod 4, splint 3 can drive mounting panel 11 and roller 12 through connecting rod 10 and move together, and at this in-process, connecting rod 10 can be to splint 3 supporting role to guarantee the stationarity when splint 3 moves, and then after splint 3 and bell and spigot mould body 2 contact, splint 3 can be stable press from both sides tight in the position of 2 sides of bell and spigot mould body, guarantee the stability of bell and spigot mould body 2.

As shown in fig. 3, the top view of the clamping plate 3 is arc-shaped, and a rubber protection pad 13 is fixedly connected to one side of the clamping plate 3 close to the socket die body 2;

splint 3 of arc design more does benefit to the surface laminating with bell and spigot mould body 2, and when splint 3 inboard rubber protection pad 13 then can increase frictional force between splint 3 and the bell and spigot mould body 2, rubber protection pad 13 can also protect bell and spigot mould body 2 surface not damaged.

As shown in fig. 2 and 3, the length of the movable block 71 located at the outer part of the sliding groove is smaller than the maximum displacement of the limiting strip 72 along the horizontal direction of the limiting groove;

when the movable block 71 moves inwards the chute due to the blocking of the bell and spigot mold body 2, the part of the movable block 71, which is positioned outside the chute, can be completely taken into the chute, so that the bell and spigot mold body 2 is clamped and fixed by matching with the clamping plate 3.

As shown in fig. 3, the two movable blocks 71 are symmetrical with respect to the screw 4, and the moving direction of the movable blocks 71 is located in the diameter direction of the socket die body 2;

when two movable blocks 71 are in contact with the socket die body 2 under the driving of the clamping plate 3, the two movable blocks 71 can uniformly apply pressure to the socket die body 2, and the direction of the pressure can be perpendicular to the surface of the socket die body 2, so that the socket die body 2 can be better fixed under the squeezing action of the movable blocks 71.

The working principle of the invention is as follows:

referring to the attached drawings 1-4 of the specification, before concrete is poured into the bell and spigot mould body 2, the bell and spigot mould body 2 is firstly placed between two clamping plates 3, and then two screw rods 4 are sequentially rotated, so that the two clamping plates 3 can be pushed by the screw rods 4 to approach the bell and spigot mould body 2;

when the movable block 71 on the inner side of the splint 3 contacts the bell and spigot mold body 2, the movable block 71 starts to move towards the inside of the sliding groove due to the blocking of the bell and spigot mold body 2 along with the continuous rotation of the screw 4, and meanwhile, the limiting strip 72 is limited by the limiting groove, so that the movable block 71 can tightly cling to the surface of the bell and spigot mold body 2 to slide downwards under the matching action of the limiting strip 72 and the limiting groove;

along with the downward movement of the movable block 71, the telescopic rod 73 and the spring 74 can be gradually compressed, and the bell and spigot die body 2 can be tightly and tightly pressed with the base 1 under the downward friction force of the movable block 71 on the bell and spigot die body, so that the stability of the bell and spigot die body 2 in concrete pouring is ensured;

after the movable block 71 completely enters the chute, the two clamp plates 3 can be in contact with the socket die body 2, so that the socket die body 2 is better fixed under the matching action of the two clamp plates 3 and the movable block 71, and the pouring quality of concrete is improved.

Although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications or substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
