Technical Field

[0001] This utility model relates to the field of fire protection testing technology, specifically a testing device for water hoses. Background Technology

[0002] In the field of fire supervision, hose testing devices are key equipment to ensure that the performance of fire hoses meets safety standards. Their core functions include pressure resistance testing, sealing testing, and appearance integrity inspection. It is required to use professional testing equipment to conduct rated working pressure tests (such as pressure holding tests above 1.0MPa), leak detection at joint connections, and visual or instrument-assisted inspections of surface wear, aging cracks, etc.

[0003] When conducting abrasion resistance testing on fire hydrant hoses, the common method is to cut the hose and attach both ends to a limiting module using a sleeve connection, then clamp and secure it with retaining rings. However, this method is cumbersome and time-consuming, especially when testing hoses of various sizes. Therefore, we propose a hose testing device. Utility Model Content

[0004] The purpose of this utility model is to provide a testing device for fire hoses, in order to solve the problem mentioned in the background art that when testing the abrasion resistance of fire hydrant hoses, the common method is to cut the hose and attach both ends to the limiting module in a sleeve manner, and then clamp and fix it with a fixing ring. However, this method is cumbersome and makes it very time-consuming and labor-intensive when testing hoses of various sizes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a detection device for water hoses, comprising: an operating table, a guide groove on the upper surface of the operating table, a limiting component with an adjustable outward expansion diameter on the outer surface of the guide groove, and an adjusting component with an adjustable spacing inside the operating table.

[0006] The limiting component includes a support base, a rotating cylinder movably connected to the side surface of the support base, a rotating rod fixedly connected through the inside of the rotating cylinder, a rotating shaft fixedly connected to the outer surface of the rotating cylinder, an outer expansion plate fixedly connected to the outer surface of the rotating shaft, and a pushing groove opened through the outer surface of the outer expansion plate.

[0008] The bottom of the support base is fixedly connected to a sliding seat, and the support base is slidably connected to the inner surface of the guide groove through the sliding seat.

[0009] The adjustment assembly includes a bidirectional screw, a rotating disk is fixedly connected to the outer surface of the bidirectional screw, a rotating handle is fixedly connected to the side surface of the rotating disk, a positioning seat is movably connected to the outer surface of the bidirectional screw, and the side surface of the positioning seat is fixedly connected to the inside of the operating table.

[0010] The bidirectional screw is rotatably connected inside the control panel.

[0011] This utility model has at least the following beneficial effects:

[0012] 1. In use, the limiting component, through the rotating rod, the outer expansion plate, and the outer expansion plate in the setting, can realize the support diameter of the outer expansion plate when rotating the rotating shaft. This allows the limiting component to directly fix water hoses of different sizes during wear resistance testing, greatly improving the efficiency of testing various water hoses and avoiding the time and manpower waste caused by cumbersome replacement and installation.

[0013] 2. In use, the bidirectional screw and rotating handle in the adjustable assembly allow the operator to slowly and evenly rotate the rotating handle according to the actual specifications of the water hose and the testing requirements. This enables the limiting assembly to accurately adapt to different water hose diameters, ensuring that the water hose is securely clamped and improving the accuracy and reliability of the testing.

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a detection device for water hoses, comprising: an operating table 1, a guide groove 2 on the upper surface of the operating table 1, a limiting component 3 with an adjustable outward expansion diameter on the outer surface of the guide groove 2, and an adjusting component 4 with an adjustable spacing inside the operating table 1.

[0021] In use, the rotating rod 33, the outer expansion plate 35, and the outer expansion plate 38 in the limiting component 3 allow the supporting diameter of the outer expansion plate 38 to be adjusted when the rotating shaft 34 is rotated. This enables the limiting component 3 to adapt to various specifications of fire hoses, such as common DN50, DN65, and DN80 hoses. By simply rotating and adjusting the supporting diameter, the hoses can be stably supported and inspected, greatly improving the applicability of the inspection device and reducing the cost and space required for equipping multiple inspection devices for different specifications of hoses.

[0022] The limiting component 3 includes a support base 31, a rotating cylinder 32 movably connected to the side surface of the support base 31, a rotating rod 33 fixedly connected through the inside of the rotating cylinder 32, a rotating shaft 34 fixedly connected to the outer surface of the rotating cylinder 32, an outer expansion plate 35 fixedly connected to the outer surface of the rotating shaft 34, a pushing groove 36 opened through the outer surface of the outer expansion plate 35, a connecting rod 37 movably connected inside the pushing groove 36, an outer expansion plate 38 fixedly connected to the side surface of the connecting rod 37, a positioning plate 39 movably connected to the outer surface of the connecting rod 37, a positioning groove 310 opened through the outer surface of the positioning plate 39, a positioning rod 311 movably connected inside the positioning groove 310, and a sliding seat 312 fixedly connected to the bottom of the support base 31.

[0023] In use, the rotating rod 33 is manually rotated, causing the rotating rod 33 to drive the rotating shaft 34 to rotate through the rotating cylinder 32. The rotating shaft 34 is fixedly connected to the center of the outer expansion plate 35. The rotation of the rotating shaft 34 drives the outer expansion plate 35. Since the connecting rod 37 is sleeved inside the pushing groove 36, the outer expansion plate 38 will be pushed outward through the pushing groove 36 when the outer expansion plate 35 rotates. The positioning rod 311 is fixedly connected to the side surface of the outer expansion plate 38 and is movably connected inside the positioning groove 310. Under the guidance of the positioning groove 310, the outer expansion plate 38 will move outward along the fixed position, so that the outer expansion plate 38 can support the inner wall of fire hose pipes with different apertures, playing a role in fixing the water hose and keeping the water hose stable during wear resistance testing.

[0024] The adjustment assembly 4 includes a bidirectional screw 41, a rotating disk 42 is fixedly connected to the outer surface of the bidirectional screw 41, a rotating handle 43 is fixedly connected to the side surface of the rotating disk 42, and a positioning seat 44 is movably connected to the outer surface of the bidirectional screw 41. The side surface of the positioning seat 44 is fixedly connected to the inside of the operating table 1.

[0025] In use, the handle 43 is manually cranked, which drives the bidirectional screw 41 to rotate through the rotating disk 42. Since the two ends of the bidirectional screw 41 rotate in different directions, when one end of the bidirectional screw 41 rotates, the bidirectional screw 41 will drive the support base 31 to move towards each other on the upper surface of the operating table 1, thereby achieving the limitation and fixation of water hoses of different lengths, effectively improving the flexibility of the device.
