[0030] Another core of the utility model is to provide a pipe clamp device including the above-mentioned plum blossom type pipe clamp anti-loosening device.

[0031] It should be noted that the directions or positional relationships indicated by “upper”, “lower”, “front”, “back”, etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present application.

[0032] The present application provides a plum blossom hole type pipe clamp anti-loosening device, which is used to be installed on the pipe clamp, and the anti-loosening device includes: a plum blossom hole piece 1 and a locking assembly 4;

[0033] The plum blossom hole piece 1 is used to be sleeved on the fixing component 2 and clamped with the fixing component 2, and the fixing component 2 is used to fix the pipe clamp. The outer periphery of the plum blossom hole piece 1 is provided with a plurality of grooves 3;

[0034] The locking assembly 4 is disposed in the groove 3 of the plum blossom hole piece 1 and is used to prevent the plum blossom hole piece 1 from rotating.

[0035] Please refer to the attached Figure 1 The pipe clamp includes an upper clamping block 6 and a lower clamping block 7. The upper clamping block 6 and the lower clamping block 7 are two block-shaped components that are arranged in contact with each other. Corresponding arc-shaped notches are arranged in the middle of the lower side of the upper clamping block 6 and the middle of the upper side of the lower clamping block 7. The two arc-shaped notches can be combined into a cylindrical hollow structure. The pipe can be clamped by the upper clamping block 6 and the lower clamping block 7. The upper clamping block 6 and the lower clamping block 7 are connected by a fixing component 2.

[0036] Specifically, the plum blossom hole piece 1 is an annular structure and is sleeved on the outer periphery of the fixing component 2. The plum blossom hole piece 1 and the fixing component 2 are in a snap-fitting relationship so that the plum blossom hole piece 1 and the fixing component 2 can rotate synchronously. The outer periphery of the plum blossom hole piece 1 is provided with a plurality of grooves 3, and a locking component 4 is provided in the groove 3. The locking component 4 can be snap-fitted with both ends of the groove 3, thereby limiting the rotation of the plum blossom hole piece 1 to prevent the pipe clamp from loosening. The structure provided by the present application has the advantages of simple structure and low cost. There is no need to disassemble or replace the original pipe clamp, which is conducive to promotion and convenient for inspection and maintenance.

[0037] On the basis of the above embodiment, a top plate 5 is provided between the plum blossom hole plate 1 and the pipe clamp, the top plate 5 is used to buffer the fastening force of the fixing assembly 2 and to improve the clamping effect of the pipe clamp, and the locking assembly 4 is provided on the top plate 5 .

[0038] Specifically, the top plate 5 can buffer the tightening force of the fixing component 2 on the upper clamp block 6 and the lower clamp block 7. The top plate 5 is generally arranged on the upper surface of the upper clamp block 6, and the bottom plate 8 can also be arranged on the lower surface of the lower clamp block 7. The fixing component 2 passes through the top plate 5, the upper clamp block 6 and the lower clamp block 7, and is connected to the bottom plate 8 to achieve the connection and tightening of the top plate 5, the upper clamp block 6, the lower clamp block 7 and the bottom plate 8. The locking component 4 is arranged on the upper surface of the top plate 5, and there is no need to improve the structure of the upper clamp block 6 or the lower clamp block 7 of the pipe clamp.

[0039] Optionally, the top plate 5 can be modified from the existing top plate, that is, it is necessary to add a mounting hole for installing the locking assembly 4 on the top plate 5. The mounting hole can be directly added to the top plate 5 of the pipe clamp that has been installed without disassembling the top plate 5. Compared with modifying the upper clamp block 6 or the lower clamp block 7, the cost and operation difficulty are lower.

[0040] Based on the above embodiment, the groove 3 is a semicircular groove, and multiple grooves 3 are evenly distributed on the outer circumference of the plum blossom hole plate 1. The locking component 4 is a cylindrical component, and the center of the groove 3 is set on the outer circumference of the plum blossom hole plate 1.

[0041] Specifically, the locking component 4 is a cylindrical component and corresponds to the semicircular groove 3, and the sizes of the two are matched (that is, the diameter of the locking component 4 is equal to the diameter of the groove 3, and the diameter of the groove 3 can be slightly larger than the locking component 4, which can avoid the increase in installation difficulty caused by part size errors and facilitate the installation of the locking component 4). When the locking component 4 is inserted into the groove 3, the groove 3 fits tightly to the locking component 4, so that the plum blossom hole piece 1 will no longer rotate after the installation of the locking component 4 is completed. Correspondingly, the center of the groove 3 is set at On the circumference of the plum blossom hole plate 1, the number of grooves 3 is n, and the angle between the center of adjacent grooves 3 and the line connecting the center of the plum blossom hole plate 1 is α°, n=360° / α°, 360 is an integer multiple of α, and the value range of n is preferably at least 12, that is, the number of grooves 3 should be as large as possible. When the fixing component 2 is tightened and the plum blossom hole plate 1 is sleeved on the outer periphery of the fixing component 2, at least one groove 3 can correspond to the mounting hole, and multiple grooves 3 are closely arranged to facilitate the installation of the plum blossom hole plate 1 and the locking component 4.

[0042] Optionally, the groove 3 may be a groove of other shapes, such as circular, triangular, arc-shaped, ratchet-shaped, polygonal, and similar shapes. The corresponding locking assembly 4 is configured as an expansion screw of a cylinder, a triangular prism, etc., so as to achieve the limiting of the plum blossom hole piece 1. Considering disassembly and replacement, the expansion screw may not be selected and the locking assembly 4 can be fixed by a snap-on method.

[0043] On the basis of the above-mentioned embodiment, two of the plum blossom hole pieces 1 and the locking components 4 are provided, the two plum blossom hole pieces 1 are respectively used to be sleeved on the outer peripheries of the two fixing components 2, and the two locking components 4 are arranged between the two plum blossom hole pieces 1.

[0044] Specifically, the number of plum blossom hole pieces 1 and locking components 4 depends on the number of fixing components 2. Generally speaking, a fixing component 2 is respectively provided at both ends of the upper clamp block 6 and the lower clamp block 7, and the two fixing components 2 are respectively arranged at positions close to the ends of the upper clamp block 6 and the lower clamp block 7. Therefore, the space reserved at the two ends of the corresponding top plate 5 is small and is not suitable for the installation of the locking component 4. Therefore, the locking component 4 is preferably arranged on the top plate 5 between the two plum blossom hole pieces 1.

[0045] On the basis of the above embodiment, the grooves 3 are evenly distributed on the half circumference of the plum blossom hole plate 1 facing the locking assembly 4 .

[0046] Specifically, since the fixing component 2 is arranged at the two ends of the upper clamping block 6 and the lower clamping block 7, and the locking component 4 is arranged between the two plum blossom hole plates 1, it is only necessary to set the groove 3 on the half circumference of the plum blossom hole plate 1 facing the locking component 4. During processing, it is only necessary to set the groove 3 on the upper half circumference of the plum blossom hole plate 1, which reduces the processing difficulty and processing cost. During installation, the half circumference of the plum blossom hole plate 1 with the groove 3 is facing the locking component 4.

[0047] On the basis of the above embodiment, the locking assembly 4 is a fastening bolt, and a threaded hole 9 for installing the locking assembly 4 is provided on the top plate 5 , and the big head end of the fastening bolt is buckled on the surface of the plum blossom hole plate 1 .

[0048] Specifically, both the locking assembly 4 and the fixing assembly 2 can be fastened with a fastening bolt, and the locking assembly 4 can be installed on the upper surface of the top plate 5 by means of a threaded connection, and the end of the fastening bolt is provided with a large head end, the size of the large head end is larger than the size of the groove 3, and can be buckled on the surface of the plum blossom hole piece 1, thereby preventing the plum blossom hole piece 1 from falling off, as shown in the attached Figure 1 As shown, the pipeline is arranged horizontally, and the fixing component 2 is arranged vertically. The plum blossom hole piece 1 is sleeved on its outer periphery, and its limitation is achieved by the locking component 4. When the pipeline is arranged vertically, when fluid passes through the pipeline, the pipeline is prone to a certain degree of vibration. When the pipeline is arranged outdoors and experiences windy conditions, a force will be exerted on the plum blossom hole piece 1. The big head end of the fastening bolt can also limit the plum blossom hole piece 1 when the pipeline is arranged vertically to prevent it from falling off after being subjected to external forces.

[0049] Optionally, multiple threaded holes 9 can be provided and evenly distributed on the periphery of the through hole provided on the top plate 5. The distance between the threaded hole 9 and the through hole is the same as the radius of the plum blossom hole plate 1. Multiple grooves 3 are provided on the periphery of the plum blossom hole plate 1 to ensure that when the fixing component 2 is rotated to the tightening state, at least one groove 3 on the plum blossom hole plate 1 can correspond to the threaded hole 9, so as to facilitate the installation of the locking component 4.

[0050] In some embodiments, the plum blossom hole piece 1 is a ring-shaped component and a hexagonal hollow portion is provided on the inner periphery of the plum blossom hole piece 1 .

[0051] Specifically, the shape of the inner circumference of the plum blossom hole piece 1 corresponds to the fixed component 2. The fixed component 2 is a hexagonal bolt, and the shape of the inner circumference of the plum blossom hole piece 1 should be a hexagonal prism to achieve the clamping connection between the two to prevent the plum blossom hole piece 1 and the fixed component 2 from rotating relative to each other. The opposite side distance S of the hexagonal inner hole in the middle of the plum blossom hole piece 1 = the opposite side distance of the hexagonal bolt + 1mm.

[0052] Optionally, when the fixing component 2 is a triangular bolt, a quadrangular bolt, etc., the shape of the hollow portion in the plum blossom hole plate 1 is correspondingly selected to be a triangular prism or a quadrangular prism.

[0053] On the basis of the above-mentioned embodiment, a gasket is provided between the plum blossom hole plate 1 and the fixing component 2 , and the gasket is used to increase the friction between the plum blossom hole plate 1 and the fixing component 2 .

[0054] Specifically, the gasket is preferably an annular rubber gasket, the inner circumference of which is larger than the size of the large end of the fixing component 2, but should be smaller than the minimum distance from the center of the plum blossom hole plate 1 to the groove 3 to avoid affecting the installation of the locking component 4.

[0055] Optionally, a rubber gasket may be provided between the locking assembly 4 and the top plate 5 to improve the fastening effect of the locking assembly 4 .

[0056] Based on the above embodiment, it also includes a sensor, a control system and an alarm. The sensor is used to be set on the pipe clamp and detect the clamping state of the pipe clamp. The sensor is electrically connected to the control system and is used to transmit the detection result to the control system. The control system is electrically connected to the alarm and is used to determine whether to activate the alarm according to the detection result.

[0057] Specifically, a sensor (not shown in the figure) is set on the upper clamping block 6 or the lower clamping block 7 of the pipe clamp to monitor the distance between the upper clamping block 6 and the lower clamping block 7 in real time. The detection result of the sensor is transmitted to the control system in real time. When the distance between the upper clamping block 6 and the lower clamping block 7 is large, that is, the upper clamping block 6 and the lower clamping block 7 are separated (the pipe clamp fails), the control system controls the alarm to emit a buzzer alarm and a sound alarm to remind the construction personnel that maintenance is needed. If the distance between the upper clamping block 6 and the lower clamping block 7 remains unchanged, that is, when the two remain in a clamped state, the alarm will not emit a buzzer alarm and a sound alarm.
