The shortcoming of hydraulic safety coupling is now: 1, in use, because often appearring in meeting, shearing ring 1 and the cut-out of cut pipe assembly 2 move, therefore can there is the situations such as local deformation, wearing and tearing in the opening 5 of shearing ring 1, the value of shearing ring 1 is relatively low, need repairing afterwards to a certain extent or change, but maintenance or replacing need lower other component of dismounting or miscellaneous equipment to realize around here, waste time and energy, and are unfavorable for that user reduces user cost and increases work efficiency; 2, when processing joint sleeve 3, because oil hole 8 diameters are less, and inclined hole 7 is small-diameter deep inclined hole, higher for operator's technical ability and equipment requirement, is unfavorable for reducing costs, as shown in Figure 1; 3, sometimes because the axial length of joint sleeve 3 is limited, process equipment cannot be realized and process inclined hole 7 as shown in Figure 1, so oil hole 8 must be disposed in the connection of cut pipe assembly with in the circumferential ring surface at 6 places, hole, as shown in Figure 2, Figure 3, Figure 4; Now due to the position of oil hole 8, also need to increase the quantity of shearing ring 1 split shed 5, so that oil hole 8 can be connected with external device, and shearing ring 1 is thin-wall part, increases the quantity of opening 5, has further improved again difficulty of processing and has reduced manufacturing efficiency.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of novel hydraulic safety coupling, and it can be changed shearing ring easily, thereby saves user cost and increase work efficiency.Meanwhile, this novel hydraulic safety coupling is easy to processing, has improved manufacturing efficiency.
A kind of novel hydraulic safety coupling of the utility model, it comprises shearing ring, joint sleeve, cut pipe assembly, and shearing ring is laterally zygomorphic two-part, on its left end external diameter, is evenly equipped with several attachment holes, and right-hand member external diameter is evenly equipped with several openings; Shearing ring is enclosed within on the outer wall of joint sleeve, and connects in aggregates by being positioned at cut pipe assembly and the joint sleeve of opening.
During assembling, the inwall of shearing ring and joint sleeve is enclosed within respectively on two sections of external diameters of mandrel, wherein the upper and lower two-part of shearing ring are enclosed within on mandrel, then adjust the position of shearing ring opening, make cut pipe assembly be positioned at opening, and realize also fastening with connecting of mandrel by the joint bolt being contained in attachment hole.Like this, when shearing ring need to be changed, as long as joint bolt is unscrewed and is taken out, can easily realize installation or removal, needn't dismantle other component, especially in the space at hydraulic safety coupling use position place hour, install, safeguard or change convenient, improve user's working efficiency, also suitably reduced user cost.

Embodiment
From Fig. 5, Fig. 6, Fig. 7, this novel hydraulic safety coupling, it comprises shearing ring 1, joint sleeve 3, cut pipe assembly 2, shearing ring 1 is laterally zygomorphic two-part, on its left end external diameter, be evenly equipped with several attachment holes 11, right-hand member external diameter is evenly equipped with several openings 5; Shearing ring 1 is enclosed within on the outer wall of joint sleeve 3, and connects in aggregates by being positioned at the cut pipe assembly 2 of opening 5 with joint sleeve 3.
As this novel a kind of improved procedure, in joint sleeve 3, be provided with horizontal oilhole 14, longitudinally oilhole 13, cavity 9, oil hole 8, several shear pipe assemblies and connect with hole 6, laterally oilhole 14 connects with one hole 6 and passes and by longitudinal oilhole 13, communicate with oil hole 8 afterwards from shearing pipe assembly; Longitudinally oilhole 13, laterally oilhole 14, one are sheared pipe assembly and are connected with hole 6, oil hole 8 and cavity 9 and form a complete oil circuit.Wherein, laterally oilhole 14 and longitudinal oilhole 13 intersect vertically; Laterally shutoff is carried out by stopping up 10 in the outer end of oilhole 14.Due to longitudinal oilhole 13 be radially, the more shallow hole of the degree of depth, the major diameter of drill bit is smaller, is conducive to process; Laterally oilhole 14 is axial slender hole, drill bit slenderness ratio is large, but because the space of processing is comparatively open, the drill bit that can suitably adopt slightly large specification, reduces slenderness ratio, and due to this hole and parallel to an axis, add and easily place man-hour, without frock, thus relatively low to equipment and operation requirements, improved manufacturing efficiency.Simultaneously, because this is novel, inclined hole 7 is revised to the hole 13 and 14 that becomes right angle intersection, so be not subject to the length restriction of coupling band 3, without oil hole 8 being arranged in the circumferential ring surface at cut pipe assembly putting hole 6 places, just do not increase the quantity of opening 5, reduced difficulty of processing and improved manufacturing efficiency yet.
