The telescopic principle of the telescopic lifting arm 2 under the action of the telescopic mechanism is as follows: starting the motor M when the telescopic lifting arm 2 is in the retraction state, and driving the gear 45 to rotate anticlockwise (the anticlockwise is set by taking the direction vertical to the paper as a reference), so that the rack 46 drives the middle knuckle arm 22 to move forwards relative to the outer knuckle arm 21; meanwhile, the extension pulling piece 41 pulls the outer joint arm 21 to extend forwards relative to the inner joint arm 23 under the pulling action of the extension pulley 42, because the outer joint arm 21, the middle joint arm 22 and the inner joint arm 23 can extend and retract relatively, the extension pulley 42 is rotatably connected to the middle joint arm 22, one end of the extension pulling piece 41 tensioned by the extension pulley 42 is fixedly connected with the rear end of the inner joint arm 23, and the other end of the extension pulling piece is fixedly connected with the rear end of the outer joint arm 21, the telescopic lifting arm 2, the extension pulley 42 and the extension pulling piece 41 are matched to form a complete movable pulley mechanism, and according to the principle of the movable pulley mechanism, the extension length of the inner joint arm 23 relative to the outer joint arm 21 is twice the extension length of the middle joint arm 22 relative to the outer joint arm 21, so that the synchronous extension of the middle joint arm 22 and the inner joint arm 23 relative to the outer joint arm 21 is skillfully realized.

In the same way, the telescopic boom 2, the extending pulley 42 and the extending traction member 41 are also matched to form a complete movable pulley mechanism. When the gear 45 is rotated clockwise by changing the direction of the motor M, the rack 46 engaged therewith moves the intermediate link arm 22 rearward relative to the outer link arm 21 until it is completely retracted, and at the same time, the retraction pulling member 43 pulls the inner link arm 23 rearward relative to the intermediate link arm 22 until it is completely retracted.

It should be noted that, in the present embodiment, the telescopic boom arm only includes three sections of arms, and the three sections of arms cooperate with the driving unit, the extending assembly, the retracting assembly, and the like of the telescopic mechanism to form a movable pulley mechanism, so as to achieve synchronous extension and retraction of the middle section of arm and the inner section of arm relative to the outer section of arm. It is understood that the telescopic boom may also comprise four-section arms, five-section arms, etc. different from the number of arms shown in the present embodiment.

For example, when the telescopic boom comprises four articulated arms, namely a first articulated arm, a second articulated arm, a third articulated arm and a fourth articulated arm (named in the order from the outside to the inside), a movable pulley mechanism is formed between three adjacent articulated arms of the telescopic boom through a telescopic mechanism.

Specifically, the front end and the rear end of the second knuckle arm are respectively rotatably connected with an extending pulley 42 and a retracting pulley 44, one end of an extending traction piece 41 is hinged with the first knuckle arm, the other end of the extending traction piece is hinged with the third knuckle arm and tensioned by the extending pulley 42, one end of a retracting traction piece 43 is hinged with the first knuckle arm, and the other end of the retracting traction piece is hinged with the third knuckle arm and tensioned by the retracting pulley 44; similarly, the front end and the rear end of the third arm section are respectively rotatably connected with an extending pulley 42 and a retracting pulley 44, one end of the extending traction piece 41 is hinged with the first arm section, the other end of the extending traction piece is hinged with the third arm section and tensioned by the extending pulley 42, one end of the retracting traction piece 43 is hinged with the first arm section, and the other end of the retracting traction piece is hinged with the third arm section and tensioned by the retracting pulley 44.

Next, the description is combinedDrawingsIs/are as followsFIG. 36ToFIG. 40The specific structure of the sliding plug door is described in detail, wherein,FIG. 36Showing a structural schematic of a sliding plug door provided by the present inventionDrawing (A)，FIG. 37Show thatFIG. 36Structural indication of unlocking state of middle handle locking deviceDrawing (A)，FIG. 38Show thatFIG. 36Structural indication of locking state of middle handle locking deviceDrawing (A)，FIG. 39 showsShowing a structural schematic of a handle lock release handleDrawing (A)，FIG. 40Showing a structural schematic of a handle locking device locking a handleDrawing (A)。

The sliding plug door comprises a door body 81 and a door body locking device 83, and the door body 81 of the sliding plug door is connected with a door frame 82 of a carriage. The door lock device 83 is driven by a handle 831 to lock the door frame 82 with the door post 811 of the vehicle compartment.

In addition, the sliding plug door further includes a handle lock device 84 having two operation states of locking and unlocking, in which the handle lock device 84 restricts the rotation of the handle 831; in the unlocked state, the handle 831 is free to rotate.

When the vehicle runs, the handle 831 is locked by the handle locking device 84, so that the rotation looseness of the handle due to vibration of a carriage and the like is prevented, and the automatic opening of a vehicle door and the scattering of goods in the vehicle are prevented. Therefore, the sliding plug door in the embodiment ensures that the vehicle has higher driving safety, and meanwhile, goods in the vehicle can be prevented from being stolen.

Meanwhile, when the door needs to be opened for loading and unloading goods and the like, the handle locking device 84 controls the handle 831 to unlock so that the handle can rotate freely, and the door is opened.

In particular, the amount of the solvent to be used,as shown in fig. 37AndFIG. 38As shown, the handle locking device 84 includes a limiting portion 841 and a base 842 connected to each other, wherein the base 842 is fixed to the door 81, the limiting portion 841 is locked to the base 842 in a locked state, the limiting portion 841 limits the rotation of the handle 831 in the locked state, and the limiting portion 841 is movable or rotatable relative to the base 842 in an unlocked state to release the limitation of the rotation of the handle 831.

It should be understood that the handle locking device 84 in this embodiment is not limited to be implemented by the limiting portion 841 and the base 842, and the handle 831 may be provided with a mounting hole, and a limiting member such as a bolt may be installed in the mounting hole to fix the bolt. However, the handle 831 has a mounting hole, so that the strength of the handle is greatly reduced, and meanwhile, the bolt needs to be installed in the mounting hole every time the handle is locked, and the bolt needs to be taken out of the mounting hole every time the handle is unlocked, so that the handle locking device has a complex structure and is inconvenient to operate.

Furthermore, the limiting portion 841 is hinged to the base 842, and the limiting portion 841 and the base 842 are respectively provided with a first locking hole 8431 and a second locking hole 8441; in addition, the handle lock 84 includes a tapered end. In operation, the limiting portion 841 rotates relative to the base 842 to make the first locking hole 8431 and the second locking hole 8441 overlap with each other, and at the same time, the lock head is locked by the first locking hole 8431 and the second locking hole 8441, and the handle locking device 84 is in a locked state. When the door needs to be opened, the lock head is firstly opened and taken out of the first locking hole 8431 and the second locking hole 8441, then the limiting part 841 rotates relative to the base 842, and the handle locking device 84 is unlocked.

It is apparent that the handle lock means 84 does not necessarily include a locking head, and a connection shaft may be inserted into the first and second locking holes 8431 and 8441 to restrict the rotation of the stopper 841. However, in the present embodiment, when the two lock holes are locked by the lock head, the two lock holes can only be unlocked by the matching key, so that the lock handle 831 has a function of preventing theft, and based on this, the lock head is preferably included in the present embodiment.

Furthermore, the limiting portion 841 is provided with a first lifting lug 843, the first lifting lug 843 is provided with the first locking hole 8431, the base 842 is provided with a second lifting lug 844, and the second lifting lug 844 is provided with the second locking hole 8441.

Specifically, the first lifting lug 843 and the limiting portion 841, and the second lifting lug 844 and the base 842 may be integrally formed or welded, and in this embodiment, the welding manner is adopted based on the fastening performance of the connection and the purpose of convenient operation.

Of course, the two locking holes may be respectively disposed on the limiting portion 841 and the base 842, but in this embodiment, when the two locking holes are respectively disposed on the corresponding lifting lugs, the strength of the limiting portion 841 and the base 842 can be ensured, and the service life of the device can be prolonged.

Specifically, the limiting portion 841 includes a fixing plate 8411 and a U-shaped plate 8412 which are welded to each other, and are vertically distributed. The fixing plate 8411 is hinged to the base 842, so that the limiting portion 841 vertically rotates relative to the base 842, and the second lifting lug 844 is arranged on one side of the fixing plate 8411 away from the door body 81 and welded to the door panel of the door body 81 at one end facing the door body 81, so that when the handle locking device 84 works, the second lifting lug 844 always keeps still. The first lifting lug 843 is arranged on one side of the fixing plate 8411 facing the door body, and when the limiting portion 841 is in a locking state, the first lifting lug 843 and the second lifting lug 844 are overlapped with each other.

Meanwhile, the U-shaped plate 8412 is arranged along the axial direction of the handle 831: (As shown in fig. 40In the vertical direction shown) and, in the locked position, the handle 831 is located within a U-shaped slot of the U-shaped plate 8412,as shown in fig. 40As shown, the handle 831 is locked by restricting vertical rotation of the handle 831 by both side walls of the U-shaped plate 8412.

In particular, the amount of the solvent to be used,FIG. 36The door locking device 83 is arranged in the door panel of the door 81, the handle 831 is positioned outside the door panel of the door 81 and is connected with the door locking device 83 through a screw rod, and a worker controls the door locking device 83 positioned in the door 81 through controlling the handle 831.

The handle lock 84 is also located outside the door panel of the door 81 and below the handle 831: (FIG. 39 showsAndFIG. 40The viewing angle shown).As shown in fig. 37AndFIG. 39 showsAs shown, in the unlocked state, the limiting portion 841 is in a natural state under the action of its own gravity, at this time, the first lifting lug 843 is separated from the second lifting lug 844, and the limiting portion 841 has no limiting effect on the handle 831.As shown in fig. 6AndFIG. 8As shown, in the locked state, the limiting portion 841 is rotated manuallyThe first locking hole 8431 and the second locking hole 8441 are overlapped at 180 degrees and locked by a lock head, at the moment, the handle 831 is positioned in the U-shaped plate 8412, and the two side walls limit the vertical rotation of the handle 831.

Of course, the relative positions of the limiting portion 841 and the base 842 are not limited to this, and the limiting portion 841 and the base 842 may be distributed left and right. In this embodiment, when the two are vertically distributed, the limiting portion 841 can rotate automatically in the unlocking state, and because the rotating direction of the limiting portion 841 is the same as the axial direction of the handle 831, the interference between the limiting portion 841 and the handle 831 in the rotating process can be avoided.

The limiting portion 841 is not limited to include the U-shaped plate 8412, and may have other shapes as long as it can limit the vertical rotation of the handle 831.

Further, in the present invention,as shown in fig. 37As shown, the mounting holes that communicate each other are seted up respectively with the both sides of base 842 to fixed plate 8411, and all are equipped with round pin axle 845 in the mounting hole of both sides to make spacing portion 841 rotatory around this round pin axle 845, simultaneously, this round pin axle 845 is fixed through split pin 846.

It is understood that the above-mentioned hinge connection between the limiting portion 841 and the base 842 is not limited to be realized by the pin 845, and other ways commonly used in the art, such as a hinge bolt, etc., can be adopted, and is not limited herein.

Please refer toFIG. 41 is a drawing showing-43, wherein,FIG. 41Is composed ofFIG. 36Top view ofDrawing (A)；FIG. 42Is composed ofFIG. 41Partial amplification of the section IDrawing (A)；FIG. 43Is composed ofFIG. 41Structural indication of matching of middle door frame and door postDrawing (A)。

In current stopper sliding door, door frame and gatepost are square tubular construction, in order to guarantee opening the door and going on smoothly of the process of closing the door, have certain clearance between the door frame and the door body, because the existence in this clearance for the vehicle can make stopper sliding door produce vibrations when the operation, and this vibrations cause a body and a door frame striking, makes the two produce fatigue damage, reduces stopper sliding door's life. Meanwhile, the existence of the gap also causes the sealing effect of the sliding plug door to be poor.

In this embodiment, the door frame 82 and the door post 811 both adopt a trapezoidal pipe structure, and a door seal 821 is arranged between the two, based onFIG. 41At the view point of-43, when the sliding plug is closed, the door post 811 moves vertically relative to the door frame 82 and presses the door seal 821, so that the door frame 82 and the door post 811 are sealed, and meanwhile, the vibration between the two is reduced, and the service life of the sliding plug is prolonged.

In this embodiment, because door frame 82 and door column 811 are the trapezoidal tube structure, when the sliding plug door was closed, compare in prior art door frame and door column and be the structure of rectangular pipe, this trapezoidal tube structure of mutually supporting can play the effect of direction, need not strictly aim at when closing the door and can close, guarantee that this sliding plug door closes smoothly. In addition, the first and second substrates are,as shown in FIG. 43In the view shown, the door 81 is along when the sliding plug is closedFIG. 11Moving up from center to bottom, the gap between the door frame 82 and the door post 811 gradually decreases. Thus, the cooperating trapezoidal tube structure further improves the seal between the door frame 82 and the door post 811.

Further, the door frame 82 is provided with a stopper 822 facing the door post 811. The stopper 822 is used to restrict the relative position between the door frame 82 and the door post 811 when the sliding plug is closed, thereby preventing the door seal 821 from being crushed when the gap therebetween is too small.

The sliding plug door in the above embodiments is opened according to the following process: first, the handle lock 84 is unlocked toAs shown in fig. 39In the illustrated state (the unlocking process is as described above), the handle 831 is freely rotated, and the door locking device 83 is controlled by the rotation of the handle 831, so that the door frame 82 and the door post 811 are unlocked by the latch (see the background art for the unlocking process of the door locking device 83),as shown in fig. 11The view angle is shown, when the door 81 moves up and down, the door 81 moves down more thanWhen the thickness of the door 81 is a distance, the door 81 is moved out of the door frame 82, and at this time, the door 81 can slide left and right along the rail: (As shown in fig. 36The view shown), the opening of the sliding door is complete. The closing process of the sliding plug door is opposite to the opening process, and the details are not repeated here.
