Abstract

The present invention discloses a reliable separation mechanism arranged between two connecting end plates of an annular clamp, which solves the problem that the release mechanism arranged between the two connecting end plates of the existing annular clamp is prone to jamming. A rectangular front panel (4) and a rectangular rear panel (7) are respectively arranged between a U-shaped upper frame (2) and a U-shaped lower frame (3). The rectangular front panel (4) and the rectangular rear panel are arranged parallel to each other. Between the rectangular front panel and the rectangular rear panel arranged parallel to each other, two pairs of swing lever mechanisms with the same structure are arranged with the vertical central axis of the two panels as the symmetry axis. The two pairs of swing lever mechanisms with the same structure are symmetrically arranged with the horizontal central axis of the two panels as the symmetry axis. A pull pin (19) is arranged at the center of the rectangular front panel, and a limiting groove is arranged on the inner end of the pull pin. The groove forms a limit for the swing lever mechanism. That is, it can ensure reliable pre-tightening of the mounted cylindrical objects and reliable separation.

Description

Technical Field

[0001] The invention relates to an annular clamp, and in particular to a mechanism arranged between two connecting end plates of the annular clamp, which can reliably separate the two connecting end plates so that the opening of the annular clamp can be reliably opened. Background Art

[0002] On a vehicle in the air or in water, cylindrical objects are often mounted by a hanging method. The hanging mechanism often adopts an annular clamp. After the cylindrical object is clamped in the annular clamp, a connectable and effectively detachable mechanism is set between the two connecting end plates of the annular clamp to achieve a large load pre-tightening of the cylindrical object so that it is reliably connected to the vehicle. When the cylindrical object needs to be removed from the annular clamp, the connectable and effectively detachable mechanism can reliably separate the two connecting end plates and allow the cylindrical object to be removed from the annular clamp after opening. The existing connectable and effectively separable mechanism uses a steel ball limit mechanism, the structure of which is: a cylinder with a through hole is connected to the upper connecting end plate of the annular hoop, a cylinder is movably arranged in the cylinder, the cylinder is connected to the lower connecting end plate of the annular hoop, a spring and a steel ball are arranged between the cylinder and the cylinder, the steel ball is limited by a pull pin, when the limit pull pin is pulled out, the limit of the limited steel ball is released, the cylinder is separated from the cylinder, the annular hoop is opened, and the cylindrical object is released. This release mechanism has high requirements for the processing precision of the limit parts, complex assembly, and time-consuming. In particular, the steel ball is prone to jamming during the release of the limit, resulting in the annular hoop port not being able to open and the cylindrical object failing to be released.

[0013] The present invention is described in detail below in conjunction with the accompanying drawings:

[0014] A reliable separation mechanism is provided between two connecting end plates of an annular clamp, comprising an annular clamp belt 1, a U-shaped upper frame 2 is connected to the upper end of the annular clamp belt 1, a U-shaped lower frame 3 is connected to the lower end of the annular clamp belt 1, a rectangular front panel 4 and a rectangular rear panel 7 are respectively provided between the U-shaped upper frame 2 and the U-shaped lower frame 3, a front panel upper end tongue 5 is provided at the center of the upper end of the rectangular front panel 4, a front panel lower end tongue 6 is provided at the center of the lower end of the rectangular front panel 4, a rear panel upper end tongue 8 is provided at the center of the upper end of the rectangular rear panel 7, and a rear panel lower end tongue 9 is provided at the center of the lower end of the rectangular rear panel 7. The rectangular front panel 4 and the rectangular rear panel 7 are arranged parallel to each other, and the two panels and the transmission mechanism therebetween are an integral whole. Between the rectangular front panel 4 and the rectangular rear panel 7, which are arranged parallel to each other, two pairs of swing lever mechanisms with the same structure are arranged symmetrically with the vertical center axis of the two panels as the symmetry axis. The two pairs of swing lever mechanisms with the same structure are arranged symmetrically up and down with the horizontal center axis of the two panels as the symmetry axis. The four groups of swing lever mechanisms are completely the same and are arranged symmetrically with each other. The specific structure of the four groups of swing lever mechanisms with the same structure is as follows: the upper left tongue pin shaft 12 is fixedly arranged between the rectangular front panel 4 and the rectangular rear panel 7. , the upper left middle pin shaft 14, the upper left side pin shaft 16 and the left middle side pin shaft 18, a straight-line swing rod block 10 is connected to the upper left tongue pin shaft 12, a V-shaped swing rod block 13 is arranged on the upper left middle pin shaft 14, a hammer-shaped swing rod block 15 is arranged on the upper left side pin shaft 16, and a zigzag swing rod block 17 is arranged on the left middle side pin shaft 18, a pin pulling installation hole 21 is arranged at the center of the rectangular front panel 4, a pin pulling installation hole 21 is arranged in the pin pulling installation hole 21, and a limiting groove is arranged on the inner end of the pin pulling 19, and the inner ends of the zigzag swing rod blocks 17 in the four groups of swing rod mechanisms with the same structure are clamped and limited at the inner ends of the pin pulling 19 In the limiting groove arranged on the head, the outer end of the zigzag swing rod block 17 is top-connected with the lower end of the imitation hammer-shaped swing rod block 15, the upper end of the imitation hammer-shaped swing rod block 15 is top-connected with the outer end of the V-shaped swing rod block 13, the inner end of the V-shaped swing rod block 13 is top-connected with the inner end of the straight-line swing rod block 10, and the outer end of the straight-line swing rod block 10 is overlapped on the frame of the U-shaped upper frame 2, that is, the limiting groove arranged on the inner end of the pull pin 19 limits the above-mentioned entire swing rod group, and the limit is transmitted to the U-shaped swing rod block 10, so that the outer end of the U-shaped swing rod block 10 can be reliably connected to the U-shaped upper frame 2.When the pin 19 is removed by the cylindrical pin-pulling seat 20, the limit groove set on the inner end of the pin 19 is released from the limit of the above-mentioned entire swing rod group, and the limit of the inner end of the zigzag swing rod block 17 by the limit groove is released. The inner end of the zigzag swing rod block 17 swings upward, causing the outer end of the zigzag swing rod block 17 to swing downward, and the limit of the lower end of the imitation hammer-shaped swing rod block 15 is released. The lower end of the imitation hammer-shaped swing rod block 15 swings inwardly, and the upper end of the imitation hammer-shaped swing rod block 15 swings outwardly, and the upper end of the imitation hammer-shaped swing rod block 15 releases the limit on the outer end of the V-shaped swing rod block 13. The outer end of the V-shaped rocker block 13 swings upward, causing the inner end of the V-shaped rocker block 13 to swing downward, thereby releasing the limit on the inner end of the I-shaped rocker block 10. The inner end of the I-shaped rocker block 10 swings downward, causing the outer end of the I-shaped rocker block 10 to swing upward, thereby releasing the overlap of the outer end of the I-shaped rocker block 10 with the U-shaped upper frame 2, causing the two panels and the entire mechanism therebetween to slide downward from the square opening of the U-shaped upper frame 2, causing the U-shaped upper frame 2 to separate from the U-shaped lower frame 3, and the port of the annular clamp is opened to ensure the falling off of the clamped cylindrical product. The transmission process of the above-mentioned limit-released rocker rod occurs simultaneously in the four rocker rod mechanisms, and the two I-shaped rocker rod blocks with upper limits on the U-shaped lower frame 3 also separate from the U-shaped lower frame 3 at the same time. That is to say, the present invention constructs a double insurance for separating the U-shaped upper frame 2 and the U-shaped lower frame 3. As long as one group of rocker rods releases the limit, the purpose of opening the port of the annular clamp can be achieved, which fundamentally overcomes the problem of easy jamming of the existing separation mechanism.

[0015] A cylindrical pin pulling seat 20 is fixedly connected to the outer end of the pin pulling pin 19, and a pair of pin pulling seat fixing tongues 22 are arranged on the cylindrical pin pulling seat 20. The pin pulling seat fixing screws 25 fix the cylindrical pin pulling seat 20 and the rectangular front panel 4 together. Only after the pin pulling seat fixing screws 25 are removed can the pin pulling pin 19 be pulled out through the cylindrical pin pulling seat 20, thereby avoiding the erroneous operation of releasing the limit. A swing rod limiting column 23 is arranged between the V-shaped swing rod block 13 and the V-shaped swing rod block 17 to protect the swing rod.

[0016] An annular clamp pre-tightening screw 24 is provided on both the I-shaped rocker arm block 10 and the other I-shaped rocker arm block 11; when the entire component between the rectangular front panel 4 and the rectangular rear panel 7 is limited between the U-shaped upper frame 2 and the U-shaped lower frame 3, the annular clamp pre-tightening screw 24 is tightened to achieve the purpose of pressing the U-shaped upper frame 2 or the U-shaped lower frame 3 inward, thereby increasing the pre-tightening between the U-shaped upper frame 2 and the U-shaped lower frame 3, ensuring that the annular clamp is reliably clamped.
