[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The core of the utility model is to provide a pointer self-locking pipe clamp anti-loosening device, which can prevent bolts from loosening and has low cost and is conducive to promotion.

[0032] Another core of the utility model is to provide a pipe clamping device including the pointer self-locking pipe clamp anti-loosening device.

[0033] 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.

[0034] Attached Figure 1 , Attachment Figure 2 With attached Figure 5 The schematic structure of the preferred embodiment of the utility model is shown. Figure 3 With attached Figure 4 The structure of the ratchet plate 4 and the top plate 6 is shown.

[0035] The present application provides a pointer self-locking pipe clamp anti-loosening device, which is arranged on the surface of the upper clamp block 1 and is used to prevent the clamping of the upper clamp block 1 and the lower clamp block 2 from loosening, and includes: a ratchet piece 4 and a pointer 5;

[0036] Among them, there are two ratchet pieces 4, which are used to be sleeved on the two fixing components 3 and clamped with the fixing components 3. The two fixing components 3 are arranged on the upper clamping block 1 and are used to connect the upper clamping block 1 and the lower clamping block 2. The outer periphery of the ratchet piece 4 is evenly distributed with a plurality of teeth to form a plurality of tooth grooves, and the two ratchet pieces 4 have the same rotation direction;

[0037] The pointer 5 is a strip-shaped piece and is rotatably disposed between the two ratchet pieces 4. The two ends of the pointer 5 are respectively inserted into the corresponding tooth grooves of the two ratchet pieces 4 and engaged with the teeth of the ratchet pieces 4. The pointer 5 is used to prevent the ratchet pieces 4 from rotating in the direction of loosening the fixing component 3.

[0038] Specifically, if Figure 5As shown, the upper clamp block 1 and the lower clamp block 2 are block-shaped components that are fitted together. The middle part of the lower side of the upper clamp block 1 and the middle part of the upper side of the lower clamp block 2 are both provided with arc-shaped notches. The two notches can be combined into a columnar hollow structure to facilitate clamping of the pipe. The upper clamp block 1 and the lower clamp block 2 are both rectangular block structures with notches, and fixed components 3 are provided at the edges on both sides thereof. The fixed components 3 are used to realize the connection between the upper clamp block 1 and the lower clamp block 2. Whether the upper clamp block 1 and the lower clamp block 2 are detachable depends on the structure of the fixed components 3.

[0039] On this basis, two ratchet pieces 4 are provided, and the two ratchet pieces 4 are respectively sleeved on the outer circumference of the two fixed components 3. A plurality of teeth are evenly distributed on the outer circumference of the ratchet piece 4, and a tooth groove can be formed between two adjacent teeth. A pointer 5 is provided between the two ratchet pieces 4. The middle part of the pointer 5 can rotate relative to the upper clamping block 1, and the pointer 5 is a strip-shaped structure. The two ends of the pointer 5 are respectively inserted into the tooth grooves corresponding to the two ratchet pieces 4 so that the two ends of the pointer 5 can be engaged with the teeth. When the fixed component 3 is loose, the fixed component 3 can transmit external force to the pointer 5 through the ratchet piece 4, and the forces on the two ends of the pointer 5 can offset each other, thereby playing an anti-loosening role and improving the anti-loosening effect of the fixed component 3. The principle can be referred to in the attached figure. Figure 1 With attached Figure 2 The tightening direction of the fixing component 3 is set to clockwise tightening. When the fixing component 3 is loose, it will rotate counterclockwise. In this way, the two ratchet pieces 4 can simultaneously transmit external force to the pointer 5, thereby offsetting and preventing loosening. In addition, the utility model is simple and easy to operate, and has low cost. Only simple processing improvements are required on the original structure to install the anti-loosening device. There is no need to disassemble or replace the original pipe clamp, so the cost is low and it is conducive to promotion.

[0040] On the basis of the above embodiment, it also includes a top plate 6 and a bottom plate 7. The top plate 6 is used to be arranged on the upper surface of the upper clamping block 1, the pointer 5 is arranged on the upper surface of the top plate 6, and the bottom plate 7 is used to be arranged on the lower surface of the lower clamping block 2. The top plate 6, the upper clamping block 1, the lower clamping block 2 and the bottom plate 7 are detachably connected through the fixing component 3.

[0041] Specifically, if Figure 5 As shown, a top plate 6 is arranged above the upper clamping block 1, and a bottom plate 7 is arranged on the lower surface of the lower clamping block 2. The dimensions of the top plate 6 and the bottom plate 7 should be the same as the surface dimensions of the upper clamping block 1 or the lower clamping block 2, or slightly larger than the surface dimensions of the upper clamping block 1 or the lower clamping block 2. The dimensions of the top plate 6 and the bottom plate 7 should not be too large to avoid waste, improve portability and reduce installation difficulty. The arrangement of the top plate 6 and the bottom plate 7 can play a buffering role when the fixing component 3 connects the upper clamping block 1 and the lower clamping block 2. The pointer 5 is rotatably arranged on the surface of the top plate 6. The top plate 6 can be modified from the top plate in the prior art, which can reduce the manufacturing cost.

[0042] On the basis of the above embodiment, the fixing component 3 is a hexagonal bolt, the ratchet plate 4 is an annular component, and the interior of the ratchet plate 4 is a hollow hexagonal prism structure to achieve a detachable connection with the hexagonal bolt.

[0043] Specifically, if Figure 5 As shown, the ratchet plate 4 is an annular columnar component, and the ratchet plate 4 has a certain thickness in the vertical direction to ensure the structural strength. The large end of the fixed component 3 is a hexagonal prism, and the interior of the ratchet plate 4 is a hollow hexagonal prism structure, and is adapted to the size of the large end of the fixed component 3, so that the ratchet plate 4 can rotate synchronously with the fixed component 3, that is, the ratchet plate 4 is restricted to prevent the fixed component 3 from rotating after it rotates.

[0044] Optionally, the large head end of the fixing component 3 can adopt a multi-prism structure such as a triangular prism, a quadrangular prism, a pentagonal prism, etc. to ensure that there is a snap-fit ​​relationship between the fixing component 3 and the ratchet plate 4, that is, to ensure that there is no horizontal relative rotation between the two. The internal hollow structure of the ratchet plate 4 needs to be set corresponding to the large head end structure of the fixing component 3 to ensure that the ratchet plate 4 can be mounted on the outer periphery of the fixing component 3 and achieve the snap-fit ​​relationship between the two.

[0045] Optionally, the size of the hollow structure inside the ratchet piece 4 can be slightly larger than the large end of the fixing component 3, and filler can be added to the gap between the two during installation to ensure sufficient engagement between the two.

[0046] Optionally, the fixing component 3 and the ratchet plate 4 may be an integrated component to ensure that no relative rotation occurs between the two.

[0047] On the basis of the above-mentioned embodiment, bolt holes 8 are provided at both ends of the top plate 6, the upper clamping block 1, the lower clamping block 2 and the bottom plate 7, and the bolt holes 8 are used to install hexagonal bolts.

[0048] For details, please refer to the attached Figure 4 With attached Figure 5 The top plate 6, the upper clamping block 1, the lower clamping block 2 and the bottom plate 7 are connected by hexagonal bolts. Therefore, it is necessary to set bolt holes 8 that pass through from top to bottom on the top plate 6, the upper clamping block 1, the lower clamping block 2 and the bottom plate 7 to ensure the reliability of the connection and ensure the clamping of the pipeline.

[0049] Optionally, the bolt holes 8 on the top plate 6, the upper clamp block 1 and the lower clamp block 2 can be ordinary through holes, and the bolt holes 8 are only set on the bottom plate 7. The connection between the top plate 6, the upper clamp block 1, the lower clamp block 2 and the bottom plate 7 can also be achieved only through hexagonal bolts and the bolt holes 8 on the bottom plate 7. This design can reduce the processing difficulty and processing cost to a certain extent.

[0050] On the basis of the above embodiment, the pointer 5 is rotatably mounted on the surface of the top plate 6 by means of a screw 9 . A screw hole 10 is provided at the center of the top plate 6 , and the screw hole 10 is used to install the screw 9 .

[0051] Specifically, as attached Figure 1 As shown, the top plate 6 is a plate-like structure that matches the upper clamping block 1, the pointer 5 is rotatably connected to the upper surface of the top plate 6 by means of screws 9, the screw hole 10 is generally arranged at the center of the surface of the top plate 6, the two fixing components 3 are symmetrically arranged about the screw hole 10, and the middle part of the pointer 5 is rotatably connected to the top plate 6 by means of screws 9, so that the two ends of the pointer 5 are respectively inserted into the tooth grooves of the ratchet plate 4, and at the same time, the two ends of the pointer 5 are subjected to the same force transmitted by the ratchet plate 4.

[0052] Optionally, soft gaskets may be provided between the screw 9 and the pointer 5 and between the pointer 5 and the top plate 6, and grease or lubricating oil may be applied to avoid direct friction between the screw 9 and the pointer 5 and between the pointer 5 and the top plate 6, thereby increasing the service life of the device.

[0053] On the basis of the above embodiment, a through hole for installing a screw 9 is provided in the middle of the pointer 5, and the size of the pointer 5 gradually decreases from the middle to the two ends.

[0054] Specifically, as attached Figure 1 With attached Figure 2 As shown, the size of the big head end of the screw 9 is larger than the size of the through hole on the pointer 5, the size of the middle part of the pointer 5 is relatively large, and the size of the pointer 5 gradually decreases from the middle part to both ends, and the middle part of the pointer 5 smoothly transitions to the two ends. For the pointer 5, the distances from the tips of its two ends to the center position of the pointer 5 are the same, that is, the pointer 5 is a centrally symmetrical structure to ensure that the two ends of the pointer 5 are inserted into the tooth grooves of the two ratchet plates 4 at the same depth.

[0055] Optionally, the pointer 5 should be made of a hard material, such as steel, iron, and stainless steel, and it should be ensured that the pointer 5 has a certain structural strength to prevent bending when force is applied to both ends of the pointer 5.

[0056] In some embodiments, the number of teeth ranges from 12 to 16, and the teeth are evenly distributed on the half circumference of the ratchet plate 4 facing the pointer 5. The end of the pointer 5 is a pawl, which is used to be inserted into the tooth groove.

[0057] Specifically, as attached Figure 1 , Attachment Figure 2 With attached Figure 3As shown, the ratchet plate 4 only needs to be provided with a plurality of evenly distributed teeth on its semicircular outer circumference, and a triangular gap, i.e., a tooth groove, is formed between adjacent teeth. The shape of the pawl at the end of the pointer 5 is set corresponding to the shape of the tooth groove, and the size of the pawl needs to be slightly smaller than the tooth groove to ensure that the pawl can be inserted into the tooth groove. The number of teeth is preferably 12 to 16 for easy adjustment, and all the teeth are evenly distributed on the half circumference of the ratchet plate 4 facing the pointer 5. In other words, the semicircle of the ratchet plate 4 away from the pointer 5 side may not be processed, which can reduce the processing difficulty and processing cost, thereby reducing the production cost.

[0058] On the basis of the above embodiment, the tooth groove included angle is 60°, and the included angle of the pawl is in the range of 55° to 60°, so that the pawl can be inserted into the tooth groove.

[0059] Specifically, the range of the pawl angle is 55° to 60°, which should be less than or equal to the tooth groove angle. On this basis, the distance of the dimensions of the relevant structure is described. Please refer to the attached Figure 2 In one embodiment, the diameter of the tube is selected as φ=32 mm;

[0060] Ratchet piece 4, pawl parameters:

[0061] The number of teeth is 12 and they are evenly arranged on the outer semicircle of the ratchet plate 4; the module M = 2; the tooth height h = 3 mm;

[0062] Tooth top thickness a = 2 mm;

[0063] The narrow side of the pipe clamp B = 30mm; the center distance of the ratchet piece 4 L = 60mm; the tooth groove angle θ = 60°; the bolt is an M10 bolt, and its opposite side s = 16mm;

[0064] Ratchet formula: tooth root radius r f =B±M, r f Select 32mm;

[0065] Tooth tip radius r2 = r f +h = 35 mm;

[0066] Hexagonal opposite side distance S = s + (0.5 ~ 1mm) = 16mm + 1mm = 17mm

[0067] Pawl formula:

[0068] Working length L1 = 2*L2 = 2*2πM = 25.12 mm;

[0069] The pawl angle α=55°.

[0070] On the basis of the above embodiment, a locking piece is further included, which is arranged on the ratchet piece 4 and is used to prevent the ratchet piece 4 from falling off from the top plate 6.

[0071] Specifically, a locking piece (not shown in the accompanying drawings) can be provided on the ratchet piece 4, and the other end of the locking piece is connected to the upper surface of the top plate 6, which can prevent the ratchet piece 4 from slipping out along the central axis direction of the fixing component 3 when the ratchet piece 4 is engaged with the fixing component 3. It should be noted that when the ratchet piece 4 is placed horizontally, that is, as shown in the attached figure, Figure 5 As shown in the figure, the ratchet piece 4 generates downward pressure through its own weight and is sleeved on the outer periphery of the fixing component 3. When the pointer self-locking pipe clamp anti-loosening device provided in the present application is placed vertically, that is, when the pipeline is set vertically, the own weight of the ratchet piece 4 cannot maintain its sleeve on the outer periphery of the fixing component 3. Therefore, it is necessary to set a locking plate and limit the ratchet piece 4 through the locking plate.

[0072] Likewise, the size of the locking piece can be relatively increased, so that when limiting the position of the ratchet piece 4, the pointer 5 is also limited to prevent it from falling off.

[0073] Optionally, when the pipeline is arranged vertically, a positioning mechanism is provided on the top plate 6 or the bottom plate 7, and the pointer self-locking pipe clamp anti-loosening device of the present application is fixed to the wall through the positioning mechanism so that the pipe clamp can eliminate pipeline vibration.

[0074] In addition to the above-mentioned pointer self-locking pipe clamp anti-loosening device, the utility model also provides a pipe clamping device including the pointer self-locking pipe clamp anti-loosening device disclosed in the above-mentioned embodiment. For the structure of other parts of the pipe clamping device, please refer to the prior art and will not be repeated in this article.

[0075] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0076] The above is a detailed introduction to a pointer self-locking pipe clamp anti-loosening device and a pipe clamping device provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
