By adjusting the relative position of the adapter rod, the locking shaft and locking hole at the end of the adapter rod can be disassembled and assembled. However, the overall disassembly and assembly is quite troublesome. Furthermore, the adapter rod, locking shaft, and other structures are prone to accumulating debris and affecting their performance when exposed to the outside for extended periods. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a ground-mounted fire pump connection that solves the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a ground-mounted fire pump connector, comprising a pipe body with a bracket fixedly connected to the bottom of the pipe body. Two sets of outlet pipes are provided on the surface of the pipe body, and connecting flanges are fixedly connected to the side ends of the pipe body. A quick-closing mechanism is provided at the end of each set of outlet pipes furthest from the pipe body. The quick-closing mechanism includes a sealing cap, two sets of grooves, and a hydraulic chamber. An insertion part is fixedly connected to the rear end of the sealing cap and inserted into the interior of the outlet pipe. Two sets of slots are provided on the surface of the insertion part. Both sets of grooves are located on the inner wall of the outlet pipe, and a telescopic spring is provided inside each set of grooves. An arc-shaped block is slidably connected to each of the two sets of grooves via the two telescopic springs. The hydraulic chamber is fixedly connected to the top of the outlet pipe. A piston slidably connects to a pull rod at one end of the hydraulic chamber, and connecting rods slidably connect to pistons at both ends of the hydraulic chamber. An auxiliary ejection mechanism is provided at the end of the sealing cap near the insertion part.

[0008] Furthermore, the ends of the two sets of arc-shaped blocks away from the telescopic spring are respectively located in the two sets of slots, and the opening size of the two sets of slots is equal to the opening size of the two sets of grooves. The two sets of arc-shaped blocks are stuck in the two sets of slots, so that the insertion part cannot leave the water outlet pipe.

[0009] Furthermore, the arc surface of the arc block faces the end of the water outlet pipe away from the pipe body, and the length of the arc block is less than the depth of the groove. When the arc surface of the arc block is squeezed, it will move into the groove and can be completely retracted into the groove.

[0010] Furthermore, the ends of the two sets of connecting rods away from the hydraulic chamber are respectively fixedly connected to the two sets of arc-shaped blocks. When the two sets of connecting rods move into the hydraulic chamber, they will drive the two sets of arc-shaped blocks to leave the slot and retract into the groove.

[0011] Furthermore, the auxiliary ejection mechanism includes an opening groove, which is located at one end near the insertion part. An ejection spring is provided inside the opening groove, and a contact plate is slidably connected inside the opening groove via the ejection spring.

[0012] Furthermore, in the initial state, the end of the contact plate away from the pop-out spring is in contact with the end of the water outlet pipe away from the pipe body, and the pop-out spring is in the initial state of being compressed. When the pop-out spring rebounds, it will cause the insertion part to move a small distance out of the water outlet pipe.

[0013] Furthermore, the contact plate is square in shape and made of rubber.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model is equipped with a quick-closing mechanism, which allows the insertion part and the closing cover to quickly close the water outlet pipe through the cooperation of components such as the arc-shaped block, the slot, and the telescopic spring. When it is necessary to remove the closing cover to use the water outlet pipe, the pull rod can be pulled upwards to remove the closing cover. The overall disassembly and assembly are simpler and more convenient, which is beneficial to use.

[0016] 2. This utility model is equipped with an auxiliary pop-out mechanism, which enables the insertion part to pop out a short distance away from the pipe body by means of the cooperation between the pop-out spring and the contact plate when the pull rod is pulled upward to make the two sets of arc blocks leave the two sets of slots, so that the slots and grooves are misaligned, thus assisting in the removal of the sealing cover.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5This utility model relates to a ground-mounted fire pump connector, comprising a pipe body 1, a bracket 2 fixedly connected to the bottom of the pipe body 1, two sets of outlet pipes 3 provided on the surface of the pipe body 1, a connecting flange 4 fixedly connected to the side end of the pipe body 1, and a quick-closing mechanism 5 provided at the end of each set of outlet pipes 3 away from the pipe body 1; the quick-closing mechanism 5 includes a sealing cover 51, two sets of grooves 54 and a hydraulic chamber 57, an insertion part 52 fixedly connected to the rear end of the sealing cover 51, the insertion part 52 being inserted into the interior of the outlet pipe 3, and the surface of the insertion part 52 being open. Two sets of slots 53 are provided, and two sets of grooves 54 are opened on the inner wall of the water outlet pipe 3. The interior of each set of grooves 54 is provided with a telescopic spring 55. The interior of each set of grooves 54 is slidably connected to an arc-shaped block 56 through the two sets of telescopic springs 55. The hydraulic chamber 57 is fixedly connected to the top of the water outlet pipe 3. A pull rod 58 is slidably connected to the piston inside one end of the hydraulic chamber 57, and a connecting rod 59 is slidably connected to the piston inside both other ends of the hydraulic chamber 57. An auxiliary ejection mechanism 6 is provided at the end of the sealing cover 51 near the insertion part 52.

[0028] As shown in the figure, the ends of the two sets of arc-shaped blocks 56 away from the telescopic spring 55 are respectively located in the two sets of slots 53, and the opening size of the two sets of slots 53 is equal to the opening size of the two sets of grooves 54. The two sets of arc-shaped blocks 56 are stuck in the two sets of slots 53, so that the insertion part 52 cannot leave the water outlet pipe 3.

[0029] As shown in the figure, the arc surface of the arc block 56 faces the end of the water outlet pipe 3 away from the pipe body 1, and the length of the arc block 56 is less than the depth of the groove 54. When the arc surface of the arc block 56 is squeezed, it will move into the groove 54 and can be completely retracted into the groove 54.

[0030] As shown in the figure, the ends of the two sets of connecting rods 59 away from the hydraulic chamber 57 are respectively fixedly connected to the two sets of arc blocks 56. When the two sets of connecting rods 59 move into the hydraulic chamber 57, they will drive the two sets of arc blocks 56 to leave the slot 53 and retract into the groove 54.

[0031] As shown in the figure, the auxiliary pop-out mechanism 6 includes an opening groove 61, which is located at one end near the insertion part 52. A pop-out spring 62 is provided inside the opening groove 61, and a contact plate 63 is slidably connected inside the opening groove 61 through the pop-out spring 62.

[0032] As shown in the figure, the end of the contact plate 63 away from the pop-out spring 62 is initially in contact with the end of the water outlet pipe 3 away from the pipe body 1, and the pop-out spring 62 is initially in a compressed state. When the pop-out spring 62 rebounds, it will drive the insertion part 52 to move a small distance out of the water outlet pipe 3.

[0033] As shown in the figure, the contact plate 63 is square in shape and is made of rubber.

[0034] A specific application of this embodiment is as follows: When connecting a water source pipe via a connecting flange 4, and it is necessary to remove the sealing cap 51, pull the lever 58 upwards. The upward movement of the lever 58 will hydraulically drive the two sets of connecting rods 59 into the hydraulic chamber 57. The movement of the two sets of connecting rods 59 into the hydraulic chamber 57 will cause the two sets of arc-shaped blocks 56 to move away from the two sets of slots 53 and retract into the corresponding grooves 54. At this time, the sealing cap 51 and the insertion part 52 can be separated from the water outlet pipe 3. When the lever 58 is released, the telescopic spring 55 will drive the arc-shaped blocks 56 and the connecting rods 59 to return to their original positions. Hydraulically, the lever 58 will move downwards to return to its original position. When it is necessary to reseal the water outlet pipe 3, the insertion part 52 is inserted into the water outlet pipe 3 until the sealing cap 51 is in contact with the end of the water outlet pipe 3. Initially, the curved surface of the arc-shaped block 56 is squeezed into the groove 54 by the insertion part 52, and the telescopic spring 55 is compressed. When the slot 53 moves with the insertion part 52 and coincides with the groove 54, the telescopic spring 55 rebounds and drives the arc-shaped block 56 into the slot 53. At this time, the insertion part 52 cannot leave the water outlet pipe 3, completing the sealing. The overall disassembly and assembly are simpler and more convenient, which is beneficial to use. During the process of inserting the insertion part 52 into the water outlet pipe 3, the contact plate 63 will be squeezed into the opening groove 61, and the pop-out spring 62 will be compressed. When the arc-shaped block 56 leaves the slot 53, the pop-out spring 62 rebounds and drives the insertion part 52 to pop out a small distance away from the pipe body 1 in the direction of the water outlet pipe 3, so that the slot 53 and the groove 54 are misaligned, which helps to remove the sealing cover 51.
