DETAILED DESCRIPTION

[0014] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0015] REFERENCE Figures 1-4 A kind of hydraulic oil pipe clamp, including first clamping block 1, second clamping block 7, first clamping block 1, second clamping block 7 are locked by bolt assembly 10, first clamping block 1 has first clamping groove 2, second clamping block 7 has second clamping groove 8, hydraulic oil pipe is limited between first clamping groove 2 and second clamping groove 8, first clamping block 1 has first inclined surface 6, second clamping block 7 has second inclined surface 11, second inclined surface 11 and first inclined surface 6 abut, first clamping groove 2 open mouth points to second inclined surface 11, second clamping groove 8 open mouth points to first inclined surface 6.

[0016] The first clamping block 1 and the second clamping block 7 of this device are locked together by a bolt assembly 10 to form a clamping structure. The first clamping block 1 is provided with a first clamping groove 2, and the second clamping block 7 is provided with a second clamping groove 8. The hydraulic oil pipe is placed between the first clamping groove 2 and the second clamping groove 8 for limiting and clamping. The first clamping block 1 is provided with a first inclined surface 6, and the second clamping block 7 is provided with a second inclined surface 11. The first inclined surface 6 and the second inclined surface 11 abut against each other to form a sliding fit structure. By tightening or loosening the bolt assembly 10, the first inclined surface 6 and the second inclined surface 11 can slide relative to each other along the contact surface direction, thereby changing the distance between the first clamping groove 2 and the second clamping groove 8, thus realizing the adaptive clamping of hydraulic oil pipes with different outer diameters.

[0017] This device features a sloping sliding structure design that enables adaptive adjustment of the clamping groove spacing. The opening direction of the clamping groove corresponds to the direction of the sloping surface, allowing it to automatically adapt to changes in pipe diameter during the sloping sliding adjustment process. This improves clamping efficiency and versatility, enabling reliable clamping of hydraulic hoses of various sizes without the need to replace pipe clamps of different specifications. The device is simple in structure and easy to use.

[0018] In practical use, the hydraulic oil pipe is clamped between the first clamping block 1 and the second clamping block 7. Then, the first clamping block 1 is fixed to the frame of the hydraulic system by welding or external connectors. If external connectors are used, the connection parts can be set on the first clamping block 1 according to the working conditions. For example, a fixing ear can be welded to the first clamping block 1, and then the fixing ear can be fixed to the frame by bolts.

[0019] The first clamping block 1 has several mounting holes 14, and the second clamping block 7 has a straight groove 12 corresponding to the mounting holes 14. The bolt assembly 10 partially mates with the mounting holes 14 and partially passes through the straight groove 12.

[0020] During assembly, the bolt assembly 10 first passes through the straight slot 12 on the second clamping block 7, and then locks into the mounting hole 14 on the first clamping block 1. When the bolt assembly 10 is tightened, the first clamping block 1 and the second clamping block 7 are pressed together, thereby clamping the hydraulic oil pipe in the middle.

[0021] Because the straight groove 12 of the second clamping block 7 is a groove-shaped structure, the bolt assembly 10 is allowed to slide within a certain range along its length within the groove. This gives the second clamping block 7 a certain degree of freedom of movement during assembly, thereby enabling fine-tuning of the hydraulic hose clamping dimensions in conjunction with the inclined surface structure. The cooperation between the straight groove 12 and the mounting hole 14 allows for flexible adjustment of the position between the clamping blocks, facilitating the clamping of hydraulic hoses with different outer diameters.

[0022] In one embodiment, the mounting hole 14 is a threaded hole, and the bolt assembly 10 passes through the straight slot 12 and is threadedly connected to the mounting hole 14.

[0023] When the bolt assembly 10 is screwed into the first clamping block 1, its threads engage with the mounting hole 14, forming a secure locking structure. At the same time, since the straight groove 12 has a certain length, the second clamping block 7 is allowed to make fine adjustments along the bolt direction, thereby adjusting the clamping groove spacing through the inclined structure to accommodate hydraulic oil pipes of different diameters.

[0024] In another embodiment, a reinforcing plate 3 is provided on the side of the first clamping block 1 away from the second clamping block 7. The mounting hole 14 is a through hole. The bolt assembly 10 passes through the straight slot 12 and the mounting hole 14 in sequence and is threadedly connected to the reinforcing plate 3. The first clamping block 1 and the second clamping block 7 are nylon blocks, and the reinforcing plate 3 is a metal plate.

[0025] In this structure, the bolt assembly 10 is connected through multiple components and finally secured by a threaded end provided by the reinforcing plate 3. The reinforcing plate 3 can be made of metal to improve overall rigidity and locking strength. The straight slot 12 also provides a clamping block position adjustment function, which, in conjunction with the inclined structure, enables oil pipe clamping.

[0026] A washer 13 is installed between the head of the bolt assembly 10 and the second clamping block 7 to prevent the head of the bolt assembly 10 from passing through the straight slot 12.

[0027] refer to Figure 4 The first clamping groove 2 has an arc-shaped groove along the radial section of the hydraulic oil pipe.

[0028] As another implementation method, refer to Figure 2 The first clamping groove 2 has a first positioning surface 4 and a second positioning surface 5. The first positioning surface 4 and the second positioning surface 5 are set at acute angles, right angles, or obtuse angles. The second clamping groove 8 has a third positioning surface 9 that is flat or arc-shaped. The hydraulic oil pipe abuts against at least a portion of the first positioning surface 4, a portion of the second positioning surface 5, and a portion of the third positioning surface 9.

[0029] In this embodiment, reference Figure 2 The pipe clamp achieves three-point positioning and clamping of the hydraulic oil pipe through a multi-faceted positioning structure, thereby enhancing stability and versatility.

[0030] Specifically, the first clamping block 2 is provided with a first clamping groove 2, and the groove has a first positioning surface 4 and a second positioning surface 5. The second clamping block 7 is provided with a second clamping groove 8, and a third positioning surface 9 is provided in the groove. The positioning surface can be a plane or an arc surface, which is used to form contact support with the hydraulic oil pipe.

[0031] When the hydraulic hose is placed between the first clamping groove 2 and the second clamping groove 8, its outer wall will contact at least three positioning surfaces: a part of the first positioning surface 4, a part of the second positioning surface 5, and a part of the third positioning surface 9. These three contact points form a stable triangular support structure in space, realizing three-point positioning and clamping of the hydraulic hose.

[0032] The first clamping block 1 and the second clamping block 7 can be docked to form a three-dimensional rectangular block. The docking forms a standardized rectangular block, which allows the pipe clamps to be neatly stacked and tightly arranged during transportation, reducing space waste, improving packaging efficiency, and reducing logistics costs. In addition, the rectangular block has a regular shape and is not easy to get stuck or roll over during transportation or handling, reducing the risk of damage.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
