Detailed description of the invention
As shown in Figure 1, flexible water pot latching device has A, a, B, b, C, c, D, d totally 8 places, due to the general paired use of water pot, wherein A, B, C, D are outside I latching device everywhere, can can realize locking by a push rod easily, a, b, c, d are inner side II fork arm latching device everywhere, and inner side does not have operational space, can only be by operating in water pot end.A, d two places, due near water pot end, also can realize locking by a push rod easily, and b, c two places and water pot end, apart from too far away, cannot directly be locked.Can only realize by means of a device (fork arm latching device) locking and release in water pot end.
The specific operation process of flexible water pot latching device comprises locking and two processes of release, is described below for the specific embodiment of the present invention.
embodiment 1
Specific embodiments of the invention, as shown in Figure 1 to Figure 3, a kind of flexible water pot latching device 1, this flexibility water pot comprises folding hollow stent 2, water pot bottom bottom fork arm 203, this collapsible hollow stent 2 is identical with collapsible hollow stent of the prior art, described hollow stent 2 comprises that multilayer (can be 3 to 6 layers, also can be 2 layers or more multi-layered, the number of plies of framework can design according to actual needs) framework 204, between described each framework 204, be provided with linkage rod group 203, described linkage rod group 203 comprises two hinged connecting rods, described two connecting rods are hinged on respectively on two adjacent described frameworks 204, the other end of described connecting rod is sliding end, described rod slide end is slidably disposed on adjacent described framework 204, described two frameworks 204 at least offer chute 201 on one of them person, described linkage rod group 203 at least one of them person's sliding end is articulated with roller 2011, described roller 2011 is slidably mounted in described chute 201 (as shown in Figure 5), the minimum spacing of described rotating shaft (being rocker pins 108) and described roller 2011 is less than the length of described screens post (rocking bar 105).The hoisting and reduce and control with oil cylinder 3 of hollow stent 2.
As Fig. 2, shown in Fig. 6, latching device 1 of the present invention improves and is, bottom or certain layer of described framework 204 are provided with rotating shaft (being rocker pins 108), described rotating shaft is fixed on described framework 204 by bearing 107, in described rotating shaft, be hinged with screens post (rocking bar 105), the free end of described screens post can limit the movement (for example holding out against or locked described rod slide end) of described rod slide end, the minimum spacing of described rocker pins 108 and described rod slide end is less than the length of described rocking bar 105, so that described rocking bar 105 can limit the slip of described rod slide end after putting down, on described rocking bar 105, be fixed with knee 109, described knee 109 has an angle (as shown in Figure 9) with described rocking bar 105, described knee 109 is movably hinged by stay rod pin 106 with described stock 102, be provided with handle 101 in described stock 102 ends, described stock 102 extends to the edge of described flexible water pot.Described pressure break hollow stent is provided with clamp 103, and described clamp 103 is fixed on described pressure break hollow stent by bolt 104, and described clamp 103 is provided with and coordinates the limiting component that limits described stock 102 positions with described stock 102.In the present embodiment, as shown in Figure 6 to 8, clamp 103 1 sides have broached-tooth design, and the limiting component of stock 102 correspondences also has the projection coordinating with described broached-tooth design, for limiting the position of stock 102.The setting of said structure is for the rotation of rocking bar 105 in locking and releasing process being changed into the promotion of handle 101 and pulls, making to operate more convenient.
Locking process: after oil cylinder 3 puts hollow stent 2 jackings in place, oil cylinder 3 continues a little also pressurize of jacking.Lifting handle 101 is separated from the broached-tooth design of clamp 103 broached-tooth designs and stock 102, promote handle 101, stock 102 drives rocking bar 105 to rotate around rocker pins 108 by stay rod pin 106, rocking bar 105 turns to drop to the ground state and embedding in described chute 201 of level from obliquity, prop up the sliding end of described linkage rod group 203, limit its action radius.After rocking bar 105 rotate in place, stock 102 broached-tooth designs are embedded in clamp 103 broached-tooth designs, finally put down oil cylinder 3, water pot bottom bottom fork arm 203 contacts and clamps to realize with rocking bar 105 ends and lock.Fig. 2 is the water pot (mode of operation) under locking state, and Fig. 6 a is independent latching device 1 schematic diagram at locking configuration state.
Releasing process: contrary with locking process, oil cylinder 3 continues a little also pressurize of jacking.Lifting handle 101 is separated from the broached-tooth design of clamp 103 broached-tooth designs and stock 102, pull handle 101, stock 102 drives rocking bar 105 to rotate around rocker pins 108 by stay rod pin 106, rocking bar 105 is from the drop to the ground interior disengaging of chute 201 of position of level, and turn to heeling condition, depart from the sliding end of linkage rod group 203 and non-interference with roller 2011.After rocking bar 105 rotate in place, stock 102 broached-tooth designs are embedded in clamp 103 broached-tooth designs, water pot bottom bottom fork arm 203 is separated from and realizes release with rocking bar 105 ends, slowly puts down afterwards oil cylinder 3 tank frame 2 is shunk.Fig. 3 is the water pot (travelling position) under released state, and Fig. 6 b is independent latching device 1 schematic diagram at released state.
embodiment 2
Specific embodiments of the invention, its structure is similar to Example 1, difference be described two frameworks 204 at least one of them person be provided with sliding sleeve 202, described linkage rod group 203 at least one of them person's sliding end is articulated with described sliding sleeve 202(as shown in Figure 4), the minimum spacing of described rotating shaft (being rocker pins 108) and described sliding sleeve 202 is less than the length of described screens post (rocking bar 105).
In embodiment 1, the locking mode of rocking bar 105 is: rocking bar 105 props up the sliding end of described linkage rod group 203, thereby controls its action radius, realizes locking.The concrete locking process of the present embodiment and releasing process and embodiment 1 are basically identical.In the time that described framework 204 need to be locked, the locking mode of rocking bar 105 is: rocking bar 105 turns to the level state of droping to the ground from obliquity, it does not embed in described chute 201, but near on the described described framework 204 that is provided with sliding sleeve 202, and prop up the sliding sleeve 202 of the sliding end of described linkage rod group 203, on described sliding sleeve 202, have the parts of realizing location with screens post, by the sliding position of restriction sliding sleeve 202, thereby the sliding scale of the sliding end of control link group 203, realizes locking.
The present invention is not limited to the structure of describing in above-described embodiment.The present invention can also be applicable to the flexible water pot of pressure break of other similar structures.As the framework of the flexible water pot of pressure break is triangle or polygon, the present invention is applicable equally.All any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
