Abstract
The utility model discloses a suspension rotor connector, which comprises a suspension rod hanging element, a connecting rod, a suspension rod lower joint, a sealing ring, a bearing, a suspension rod upper joint and a screw nut, wherein one end of the connecting rod is fixedly connected with the suspension rod hanging element, the other end of the connecting rod is sheathed in an inner cavity of the suspension rod lower joint through the bearing, screw threads are arranged on a penetrating-out section of the connecting rod penetrating out of the bearing, the screw nut is screwed and connected onto the screw threads of the penetrating-out section, one end of the suspension rod upper joint is screwed and connected onto the suspension rod lower joint, the sealing ring is arranged at the combination part of the suspension rod lower joint and the suspension rod upper joint, and engine oil is fully filled in the inner cavity of the suspension rod lower joint. Because the suspension rotor connector is provided with the bearing, and in addition, the sealing ring is arranged at the combination part of the suspension rod lower joint and the suspension rod upper joint, the inner cavity of the suspension rod lower joint becomes a sealed space, in addition, high-quality engine oil is fully filled in the inner cavity provided with the bearing, sand particles in water cannot enter the inner cavity of the suspension rod lower joint, and the rotating flexibility of the bearing is ensured.
Description
Technical field
The utility model relates to a kind of undersea detection instrument, particularly relates to a kind of suspention rotor connector.
Background technique
The probe of general undersea detection instrument is all put into water with the suspention form, aim at flexibly water (flow) direction in order to guarantee that probe can rotate in water, will between the rope of probe and suspention, a device to be arranged, it is the rotor connector, as shown in Figure 1, the simplest rotor connector mainly is comprised of pin 1 ' and annulus 2 ', the rotating top that is nested with at annulus 2 ', lower end of pin 1 '.Although this to commonly use the rotor connector simple in structure cheap, rotate dumbly, larger frictional force is arranged, it is dumb to cause probe to rotate, and flow velocity hour misalignment water (flow) direction causes error of measured data, can not satisfy the requirement of actual measurement.For this reason, the dealer designs the rotor connector (as shown in Figure 2) after a kind of improve, and it is mainly by suspension rod suspension member 1 ", connecting rod 2 ", suspension rod lower contact 3 ", contiguous block 4 ", bearing 5 ", suspension rod upper connection 6 ", nut 7 " form.Its main improvements are added ball bearing exactly, although the rotor connector complex structure after the overall improvement many, frictional force greatly reduces, and rotates very flexibly, basically reaches the requirement of actual use.But after use after a while, find that resistance can be increasing, rotation also be much worse than original flexibly, when serious even can substantially turn motionless.Tracing it to its cause mainly is that the rotor connector does not possess water-tight function, and internal rotor can be intake when entry was used, and will attach into some sand grains time one bearing 5 of a specified duration " many silts that will deposit all around, resistance increases, and causes rotation dumb.
Summary of the invention
The purpose of this utility model is to provide a kind of rotation to suspend flexibly the rotor connector in midair.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of suspention rotor connector, and it comprises suspension rod suspension member, connecting rod, suspension rod lower contact, seal ring, bearing, suspension rod upper connection, nut; One end and the suspension rod suspension member of described connecting rod are affixed, the other end of connecting rod is nested with at suspension rod lower contact inner chamber by bearing, the section of passing that passes bearing at connecting rod is offered screw thread, nut is screwed onto on the screw thread of this section of passing, suspension rod upper connection one end is screwed onto in the suspension rod lower contact, junction in suspension rod lower contact and suspension rod upper connection is provided with seal ring, is full of machine oil in suspension rod lower contact inner chamber.
The outer wall of described suspension rod lower contact is stepped, and its inner chamber two ends are provided with bearing support, and two bearings are installed in respectively on the bearing support, and an end of connecting rod is affixed by bearing pin and suspension rod suspension member, and the other end of connecting rod is nested with in bearing hole and passes bearing.
Described suspension rod suspension member outer end is provided with lower lifting hole(eyelet); Described suspension rod upper connection outer end is provided with lifting hole(eyelet).
After adopting such scheme, because the utility model is provided with bearing, and be provided with seal ring in the junction in suspension rod lower contact and suspension rod upper connection, so that suspension rod lower contact inner chamber becomes an airtight space, and in being equipped with the inner chamber of bearing, this is full of high-quality machine oil, sand grain can not enter suspension rod lower contact inner chamber in water, has guaranteed the flexibility ratio of bearing rotary.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of commonly using the rotor connector;
Fig. 2 commonly uses the structural representation that improves rear rotor connector;
Fig. 3 is structural representation of the present utility model.
Embodiment
As shown in Figure 3, the utility model is a kind of suspention rotor connector, and it comprises suspension rod suspension member 1, connecting rod 2, suspension rod lower contact 3, seal ring 4, bearing 5, suspension rod upper connection 6, nut 7.
Described suspension rod lower contact 3 has hollow cavity 31, its outer wall is stepped and offer screw thread at its minor diameter outer wall, its hollow cavity 31 two ends are provided with bearing support, two bearings 5 are installed in respectively on the bearing support, one end of connecting rod 2 is affixed by bearing pin 8 and suspension rod suspension member 1, the other end of connecting rod 2 is nested with in bearing 5 bearing holes and passes bearing 5, the section of passing 21 that passes bearing 5 at connecting rod 2 is offered screw thread, nut 7 is screwed onto on the screw thread of this section of passing 21, and connecting rod 2 is spacing at suspension rod lower contact 3 hollow cavities 31 vertically, make not play vertically of connecting rod 2.
Described suspension rod upper connection 6 one ends are screwed onto on the outer wall thread of suspension rod lower contact 3, are provided with seal ring 4 in the junction of suspension rod lower contact 3 and suspension rod upper connection 6, are full of machine oil in the hollow cavity 31 of suspension rod lower contact 3.
Described suspension rod suspension member 1 outer end is provided with lower lifting hole(eyelet) 11; Described suspension rod upper connection 6 outer ends are provided with lifting hole(eyelet) 61.
Emphasis of the present utility model just is: be provided with seal ring and be full of machine oil in the hollow cavity of suspension rod lower contact.
The above, it only is the utility model preferred embodiment, can there be many places the mounting point of seal ring, so can not limit the scope that the utility model is implemented with this, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
