Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and detailed description of the invention of the present utility model is described.Wherein, identical parts adopt identical label.
Fig. 1 display be the collapsible using state schematic diagram parking catch according to a specific embodiment of the present utility model, this is collapsible parks the braking that catch 1 is mainly used in wheel 2 when aircraft is parked, and prevents wheel 2 in the slip on ground.
Fig. 2 display be the collapsible structural representation parking catch according to a specific embodiment of the present utility model, as shown in the figure, the collapsible mode of operation framed structure triangular in shape of parking catch 1 and launching of the present utility model, in flat state (see Fig. 4,5) after this framed structure is folding.
Specifically, collapsible catch 1 of parking comprises a upper axle 11, upper axle 11 is hinged with rotationally edge strip 13 after two front edge strips 12 and two, a front briquetting 14 is connected with rotationally between the lower end (that one end away from upper axle 11) of two front edge strips 12, after two edge strip 13 lower end (that one end away from upper axle 11) between be fixedly connected with one base plate 15, front briquetting 14 is removably connected by a underframe 16 with base plate 15.Further, underframe 16 is bent into U-shaped structure by Metallic rod, and two ends of described U-shaped structure are fixedly connected with front briquetting 14, and such as the two is fixedly connected by welding and is integrated.In a specific embodiment, after two edge strip 13 and base plate 15 be the integral structure cast or be welded.
In addition, after two the lower end of edge strip 13 be symmetrically arranged with hook underframe 16 U-shaped bottom the hook 131 of (relative with two ends of underframe 16), in Fig. 2, hook 131 is the hook-shaped of upward opening, is also formed with a flange 132 on the top of hook 131.Time in working order, the hook formation of this upward opening can make underframe 16 remain in hook 131 by gravity, and when underframe 16 is subject to impact effect, flange 132 can stop underframe 16 upwards to be thrown off from hook 131, define a kind of self-locking structure, the reliable difficult drop-off of sound construction, can not cause safety misadventure.
The collapsible folding process parking catch of the present utility model is further illustrated referring to Fig. 3-5.Wherein, Fig. 3 display is park according to the collapsible of a specific embodiment of the present utility model the structural representation that catch is partial folded condition; Fig. 4 display be collapsiblely shown in Fig. 3 park the structural representation that catch is complete folded state; What Fig. 5 showed is the collapsible schematic rear view parking catch shown in Fig. 4.
As shown in Figure 2-5, when of the present utility model collapsible park catch do not re-use time, can fold up and take away at random or transport, for the maintenance of outfield aircraft.Its folding process is, front edge strip 12 and rear edge strip 13 are extruded slightly to centre, make with hand or instrument upwards to lift from hook 131 bottom the U-shaped of underframe 16 to arrive at flange 132, then front edge strip 12 and rear edge strip 13 are outwards separated, underframe 16 is separated with rear edge strip 13.Afterwards, underframe 16 is upwards lifted, front edge strip 12 and rear edge strip 13 are extruded to centre simultaneously, the partial folded condition of Fig. 3 can be folded into from the mode of operation of Fig. 2.
Further, in a specific embodiment, of the present utility model collapsible park two of catch after the upper end (near that one end of upper axle 11) of edge strip 13 be also symmetrically arranged with groove 133 bottom the U-shaped holding underframe 16, try one's best in the thickness range of the front edge strip 12 of retraction two for enabling underframe 16 entirety at folded state, to reduce the volume after folding further, so that carry.
When of the present utility model collapsible park catch completely folding after, namely the state shown in Fig. 4-5 is defined, underframe 16 has deflected into the state that edge strip 12 front with two flushes completely, total is flat state, certainly, under this state, the outermost width of underframe 16 is preferably less than the most inboard width of two front edge strips 12, could form the minimum folded state of volume like this.For ease of folding location, in a specific embodiment, the width base plate 15 is preferably greater than the distance between two front edge strips 12, make folding after base plate 15 can support with two front edge strips 12 and contact and cannot rotate, thus determine last folding position.
In another specific embodiment, in order to increase the frictional ground force of catch, as shown in the figure, the bottom of front briquetting 14 is provided with anti-slip tank 141, and the end base plate 15 is also set to dentalation, is beneficial to grab ground firmly, can alleviate structural weight simultaneously.
Further, as shown in Figure 5, be also provided with in the middle of the bottom of front briquetting 14 and alleviate groove 142, can structural weight be alleviated on the one hand, anti-slip tank 141 and the area of contact on ground can be reduced on the other hand, be conducive to grabbing ground firmly.
In sum, above-mentioned collapsible reasonable in design of parking catch provided by the utility model, lightweight, collapsible, volume after folding is little, is easy to carry, and is the requisite equipment of outfield aircraft maintenance.
Although it will be appreciated by those skilled in the art that the utility model is described according to the mode of multiple embodiment, not each embodiment only comprises an independently technical scheme.So describe in specification sheets be only used to clear for the purpose of; specification sheets should integrally be understood by those skilled in the art, and regards technical scheme involved in each embodiment as the mode that mutually can be combined into different embodiment to understand protection domain of the present utility model.
The foregoing is only the schematic detailed description of the invention of the utility model, and be not used to limit scope of the present utility model.Any those skilled in the art, the equivalent variations done under the prerequisite not departing from design of the present utility model and principle, amendment and combination, all should belong to the scope of the utility model protection.
