Those skilled in the art can understand the specific meaning of the above terms in this utility model through specific circumstances.

[0032] like Figure 1 As shown in the figure, an embodiment of the present invention discloses a grouting device for prefabricated buildings, comprising a base 10, a concrete mixing box 20, and a mixing tank 30. The concrete mixing box 20 is mounted on the base 10, and the mixing tank 30 is mounted on the concrete mixing box 20. A connecting pipe 40 connects the mixing tank 30 and the concrete mixing box 20, and a pouring pipe 50 is installed on the side of the mixing tank 30 away from the concrete mixing box 20. The specific structures of the base 10, the concrete mixing box 20, and the mixing tank 30 are all prior art and will not be described in detail here. A horizontal support frame 60 is fixed to the side of the mixing tank 30 near the concrete mixing box 20, and a vertical fixing plate 70 is fixed to the end of the support frame 60 away from the mixing tank 30. A connector assembly 80 is provided at the relative position of the fixing plate 70 and the concrete mixing box 20, allowing for a detachable connection between the fixing plate 70 and the concrete mixing box 20. The number of connector assemblies 80 is not limited. By setting the fixing plate 70 and the connector 80, the mixing tank 30 and the concrete mixing box 20 can be detachably connected, which facilitates the transportation and storage of the grouting device.

[0033] Specifically, such as Figure 2 and Figure 3As shown, the connector assembly 80 includes a connector post 81, a locking block 82, and a push-pull rod 83. The connector post 81 passes through the fixing plate 70 and is inserted into the concrete mixing tank 20. The locking block 82 is located at one end of the connector post 81 near the concrete mixing tank 20. The push-pull rod 83 is located inside the connector post 81 and abuts against the locking block 82. It can move along the axial direction of the connector post 81, allowing the locking block 82 to move vertically up and down perpendicular to the axial direction of the connector post 81 to engage or disengage with the concrete mixing tank 20. In this embodiment, a through hole 71 is provided on the fixing plate 70, and a groove 21 is provided in the concrete mixing tank 20 at the position opposite to the through hole 71. The connector post 81 passes perpendicularly to the fixing plate 70 through the through hole 71 and is inserted into the groove 21 of the concrete mixing tank 20. The end of the connector 81 furthest from the concrete mixing tank 20 is integrally provided with a boss 811. When the connector 81 is inserted into the concrete mixing tank 20, the boss 811 contacts the side of the fixing plate 70 furthest from the concrete mixing tank 20, serving a positioning function. A locking block 82 is provided at the end of the connector 81 closest to the concrete mixing tank 20, that is, at the end where the connector 81 is inserted into the groove 21 of the concrete mixing tank 20. The number of locking blocks 82 is not limited; preferably, two symmetrically arranged locking blocks 82 are provided on the connector 81, located on the upper and lower sides respectively. A locking groove 22 is provided in the groove 21 opposite to the locking block 82, allowing the locking block 82 to engage with the locking groove 22. A horizontal push-pull rod 83 is sleeved inside the connector 81, with its upper and lower sides respectively abutting against the two locking blocks 82. The push-pull rod 83 is clearance-fitted with the connector post 81 and can move axially along the connector post 81, allowing the locking block 82 to move vertically up and down perpendicular to the axial direction of the connector post 81 and engage or disengage from the locking groove 22. To facilitate the movement of the push-pull rod 83, a push-pull head 831 is fixed at the end of the push-pull rod 83 away from the concrete mixing box 20.

[0034] Specifically, the push-pull rod 83 has an abutment block 84 at one end near the concrete mixing tank 20, which abuts against the locking block 82. In this embodiment, the end of the push-pull rod 83 inserted into the concrete mixing tank 20 has an integrally formed abutment block 84, and the upper and lower sides of the abutment block 84 abut against two locking blocks 82 respectively. Moving the push-pull rod 83 can drive the abutment block 84 to move axially along the insertion post 81, and the two locking blocks 82 can move vertically up and down perpendicular to the axial direction of the insertion post 81 under the action of the abutment block 84.

[0035] Specifically, the abutting block 84 is provided with an abutting slope 841, and the end of the locking block 82 near the abutting block 84 is adapted to the abutting slope 841. In this embodiment, the abutting slope 841 is symmetrically provided on the upper and lower sides of the abutting block 84, and the end of the locking block 82 near the abutting block 84 is adapted to the abutting slope 841 and can slide along the abutting slope 841. When the abutting block 84 moves toward the concrete mixing box 20, the locking block 82 can move away from the locking groove 22 along the abutting slope 841 and disengage from the locking groove 22; when the abutting block 84 moves away from the concrete mixing box 20, the locking block 82 can move toward the locking groove 22 along the abutting slope 841 and engage with the locking groove 22.

[0036] Specifically, such as Figure 3 As shown, the connector 81 has a stepped hole 812, through which the snap-fit ​​block 82 engages with the concrete mixing box 20. In this embodiment, the snap-fit ​​block 82 includes an integrally formed snap-fit ​​part 821 and an abutment part 822. The snap-fit ​​part 821 engages with the snap-fit ​​groove 22, and the abutment part 822 abuts against the abutment block 84. The end of the abutment part 822 near the abutment block 84 is adapted to the abutment slope 841 and can slide along the abutment slope 841. The connector 81 has a stepped hole 812 at a position opposite to the snap-fit ​​block 82. The snap-fit ​​block 82 is clearance-fitted with the stepped hole 812 and can move up and down along the stepped hole 812. At the same time, the stepped hole 812 limits the snap-fit ​​block 82.

[0037] Specifically, to enable the locking block 82 to quickly disengage from the locking groove 22, a first elastic element 85 is fitted onto the locking block 82, and the first elastic element 85 abuts against the stepped hole 812. In this embodiment, the first elastic element 85 is specifically a spring, which is fitted onto the locking portion 821 of the locking block 82, with one end contacting the abutting portion 822 and the other end abutting against the step of the stepped hole 812. When the abutting block 84 moves toward the concrete mixing box 20, the locking block 82, under the elastic force of the first elastic element 85, can move away from the locking groove 22 along the abutting inclined surface 841, quickly disengaging from the locking groove 22.

[0038] Specifically, a second elastic element 86 is provided at the end of the insertion post 81 near the concrete mixing box 20. The second elastic element 86 is connected to the side of the abutment block 84 away from the push-pull rod 83. In this embodiment, the second elastic element 86 is specifically a spring. Pushing the push-pull rod 83 causes the abutment block 84 to move towards the concrete mixing box 20. The first elastic element 85 rebounds, causing the locking block 82 to disengage from the locking groove 22. The second elastic element 86 is in a compressed state. When the push-pull rod 83 is released, the second elastic element 86 rebounds, causing the abutment block 84 to move towards the fixing plate 70. Under the action of the abutment block 84, the locking block 82 quickly engages with the locking groove 22.

[0039] Specifically, a positioning block 87 is provided inside the connector 81, and a push-pull rod 83 passes through the positioning block 87 and is provided with an abutment block 84. In this embodiment, in order to prevent the locking block 82 from disengaging from the abutment block 84, a positioning block 87 is fixed inside the connector 81, and the push-pull rod 83 passes through the positioning block 87 and is in clearance fit with the positioning block 87.

[0040] Specifically, a third elastic element 88 is sleeved on the push-pull rod 83, and the third elastic element 88 is located on the side of the positioning block 87 away from the abutment block 84. In this embodiment, the third elastic element 88 is specifically a spring, which is sleeved on the push-pull rod 83, with one end abutting against the push-pull rod 83 and the other end abutting against the side of the positioning plate away from the abutment block 84.

[0041] A construction method for a grouting device for prefabricated buildings includes the following steps:

[0042] Align the through hole 71 on the fixing plate 70 with the groove 21 of the concrete mixing box 20.

[0043] Pushing the push-pull head 831 causes the push-pull rod 83 to move the abutment block 84 axially along the insertion post 81, compressing the second elastic element 86 and the third elastic element 88. Under the elastic force of the first elastic element 85, the locking block 82 moves along the abutment slope 841 toward the abutment block 84 and enters the insertion post 81. At this time, the insertion post 81 is inserted into the concrete mixing tank 20 through the through hole 71. Releasing the push-pull head 831 causes the second elastic element 86 and the third elastic element 88 to rebound, causing the abutment block 84 to move toward the fixing plate 70. Driven by the abutment block 84, the locking block 82 moves along the abutment slope 841 away from the abutment block 84 and quickly engages with the locking groove 22. At this time, the first elastic element 85 is in a compressed state. The mixing tank 30 and the concrete mixing tank 20 are detachably connected through the insertion assembly 80.

[0044] Grouting is carried out.

[0045] After grouting is completed, push the push-pull head 831, causing the push-pull rod 83 to move the abutment block 84 along the axial direction of the connector post 81. This compresses the second elastic element 86 and the third elastic element 88. Under the elastic force of the first elastic element 85, the locking block 82 moves along the abutment slope 841 toward the abutment block 84, enters the connector post 81, and disengages from the locking groove 22. The entire connector assembly 80 is then pulled out, separating the mixing tank 30 and the concrete mixing tank 20 for subsequent transportation and storage.

[0046] The advantages and positive effects of this utility model are:

[0047] By incorporating a connector assembly, the mixing tank and concrete mixing box can be detachably connected, allowing for quick disassembly and assembly, facilitating transportation and storage. The structure is simple and the operation is convenient.
