Technical solutions disclosed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 6, the present application discloses a transmission device including an apparatus body 100, a handle 200, and a lock block 400. The device body 100 is a bearing base of the transmission device, and is used for mounting related parts of the transmission device, specifically, the handle 200 and the lock block 400 can be arranged on the device body 100, a transmission executing mechanism is arranged in the device body 100, so that the transmission device can be connected or disconnected with the related operation mechanisms, for example, the transmission device is arranged between the engine and the flywheel to control the connection and disconnection between the engine and the flywheel, and for example, the transmission device is arranged between two lifting drums of a loading and unloading bridge to control the linkage of the two lifting drums.

The handle 200 is a control part of the transmission to realize the state switching of the transmission, and the locking piece 400 is used for fixing the angular position of the handle 200. Specifically, the handle 200 is drivingly connected to the apparatus main body 100 and rotatable with respect to the apparatus main body 100; the locking piece 400 may be provided with a locking groove, and the locking piece 400 may be provided at a locking position on the apparatus body 100, that is, a position where the locking groove can restrain the fixing handle 200.

The locking piece 400 can be fixedly connected to the device main body 100, and the locking piece 400 is detachably connected to the device main body 100 so as to control the locking time of the locking piece 400 to the handle 200, specifically, under the condition that the handle 200 is rotated to the first angle position and the locking piece 400 is arranged at the locking position, the handle 200 can drive the transmission device to be in a transmission state, and at least part of the handle 200 can extend into the locking groove so as to realize that the handle 200 is locked and matched with the locking piece 400.

Taking the loading and unloading bridge mechanism as an example, the transmission device can be arranged between two lifting drums of the loading and unloading bridge, after the operator operates the handle 200 to rotate to the first angle position, the transmission device is switched to the transmission state, and the two lifting drums are connected through the transmission device, so that linkage is realized in actual work. At this time, the locking block 400 is arranged at the locking position of the device body 100, so that at least part of the handle 200 can extend into the locking groove, and under the constraint of the locking groove, the locking block 400 realizes locking cooperation on the handle 200, so as to lock the current position of the handle 200, prevent the handle 200 from abnormal rotation, and ensure the effective work of the transmission device.

And after the transmission work, can demolish locking piece 400 from equipment main part 100 to the realization separates in the latched position, can remove locking piece 400 like this to handle 200's locking cooperation, so that rotate handle 200 and leave first angle position, thereby make transmission switch to the off-state, and then break off the connection between two liter reels, so that the operator carries out follow-up work such as maintenance to transmission.

In summary, the arrangement of the transmission device can fix the handle 200 at the current position, so as to effectively maintain the transmission device at the current state, and improve the operation performance of the transmission device for the subsequent operation.

Further, for the specific arrangement mode of the locking block 400, the locking block 400 may be detachably connected to the device main body 100 by means of screw connection, snap connection, magnetic connection, or the like; or may be fixedly connected to the apparatus main body 100 by welding, bonding, or the like; and may be movably connected to the apparatus body 100 by means of hinge, etc., and will not be described in detail herein. It should also be noted that the locking groove may be provided as a through groove for ease of manufacturing.

Further, as shown in fig. 5, for a specific structure of the handgrip 200, the handgrip 200 may include a rocker 210 and a grip 220. The rocker 210 is provided with a through hole 211, the rocker 210 is drivingly connected to the device body 100 and can rotate relative to the device body 100, specifically, the through hole 211 may be disposed at a first end of the rocker 210, a second end of the rocker 210 is used for drivingly connecting the device body 100, and the first end and the second end are disposed oppositely.

One end of the handle 220 is provided with a locking head 221, the handle 220 is at least partially movably arranged on the through hole 211, and the locking head 221 faces to the locking position and can move along with the handle 220. Such an arrangement may improve the handling of the handle 200 as described in more detail below:

as shown in fig. 1 and 5, the locking head 221 may extend into the locking groove when the handle 200 is rotated to the first angular position and the locking block 400 is set to the locking position. Specifically, the handle 220 can be manipulated to move in a direction toward the locking position such that at least a portion of the locking head 221 extends out of the through hole 211 and into the locking slot for locking engagement with the handle 200. In this way, the locking engagement of the handle 200 by the locking block 400 can be realized by the constraint action of the locking groove on the locking head 221, so as to lock the current position of the handle 200.

When the handle 200 needs to be separated from the first angular position, the handle 220 may be manipulated to move, specifically, the handle 220 is manipulated to move in a direction away from the locking position, so that at least a portion of the locking head 221 is retracted into the through hole 211, so that the locking head 221 is separated from the locking groove, and then the handle 220 is held to drive the handle 200 to rotate away from the first angular position.

It can be seen that the handle 200 is arranged in such a manner that the handle 200 can be rotated conveniently, and the locking cooperation or unlocking cooperation between the locking block 400 and the handle 200 can be realized conveniently, which is beneficial to improving the operation performance of the transmission device.

Further, the device main body 100 may include a locking plate 300, the locking position is located on the locking plate 300, the locking plate 300 is provided with a first positioning hole 310, so that the locking plate 300 may be used as a mounting base of the locking block 400, for example, the locking block 400 may be fixed on the locking plate 300 by means of bolt connection, magnetic attraction, and the like.

With the lock block 400 in the locked position, the locking slot is located between the lock plate 300 and the rocker 210 and is positionally aligned with the first positioning hole 310. The position matching may specifically be: the locking groove is sequentially disposed with the first positioning hole 310 in a direction parallel to the moving direction of the handle 220.

Thus, when the handle 200 is rotated to the first angular position and the lock block 400 is disposed at the locking position, the lock head 221 can extend into the locking groove and the first positioning hole 310, the handle 200 is locked and engaged with the lock block 400 and the lock plate 300, respectively, and the handle 200 drives the transmission device to be in a transmission state.

In this way, the locking slot and the first positioning hole 310 together form a constraint for the locking head 221, which can form a better locking effect for the handle 200, so that the transmission device can be more effectively maintained in the current state.

Further, the locking plate 300 may be provided with reinforcing ribs to improve strength thereof and ensure effectiveness for long-term use.

Further, as shown in fig. 1 and 2, the locking plate 300 is further provided with a second positioning hole 320, and the locking grooves include a first sub-locking groove 410 and a second sub-locking groove 420.

When the locking block 400 is located at the locking position, the first sub-locking groove 410 and the first positioning hole 310 are sequentially arranged along the moving direction of the parallel handle 220, and the handle 200 can be rotated to the first angle position to drive the transmission device to be in the transmission state. At this time, the handle 200 is moved, and the locking head 221 can extend into the first sub-locking groove 410 and the first positioning hole 310 at the first angular position following the movement of the handle 200.

Thus, when the handle 200 is rotated to the first angular position and the locking block 400 is located at the locking position, the locking block 400 can be locked and engaged with the handle 200 to maintain the transmission device in the transmission state, i.e. the transmission device can realize transmission between two operating mechanisms.

Meanwhile, when the locking block 400 is located at the locking position, the second sub-locking groove 420 and the second positioning hole 320 are also sequentially located along the moving direction of the handle 220, and the handle 200 can be rotated to the second angular position to drive the transmission device to be in the off state. At this time, the operating handle 200 is moved, and the locking head 221 can extend into the second sub-locking groove 420 and the second positioning hole 320 at the second angle position following the movement of the operating handle 200.

In this way, when the handle 200 is rotated to the second angular position and the lock block 400 is set to the locked position, the lock block 400 may be locked to the handle 200 to maintain the transmission in the disconnected state, i.e., the transmission may disconnect the two operating mechanisms.

It can be seen that with this arrangement, the transmission device can not only realize effective switching between the transmission state and the disconnection state, but also be fixed in the current state more effectively through the cooperation of the first sub-locking groove 410 and the first positioning hole 310, or the cooperation of the second sub-locking groove 420 and the second positioning hole 320, so as to facilitate the subsequent operation of the transmission device.

In other alternative embodiments, as shown in fig. 3, the number of the locking grooves of the lock block 400 may be only one, and two locking positions are provided, which are referred to as a first sub-locking position and a second sub-locking position, and the first sub-locking position and the second sub-locking position are sequentially provided along a first direction, which intersects with the moving direction of the handle 220, and the lock block 400 may be switched between the first sub-locking position and the second sub-locking position.

Thus, when the handle 200 is rotated to the first angular position and the locking groove is located at the first sub-locking position, the locking groove and the first positioning hole 310 are matched in position, and the matching in position may specifically be: the locking groove is sequentially disposed with the first positioning hole 310 in a direction parallel to the moving direction of the handle 220. The lock head 221 can be inserted into the locking groove and the first positioning hole 310, the locking block 400 is locked and matched with the handle 200, and the handle 200 drives the transmission device to be in a transmission state.

And under the condition that the handle 200 is rotated to the second angular position and the locking groove is located at the second sub-locking position, the locking groove is matched with the second positioning hole 320, and the matching of the positions can be specifically as follows: the locking groove and the second positioning hole 320 are sequentially disposed in a direction parallel to the moving direction of the handle 220. The lock head 221 can extend into the locking groove and the second positioning hole 320, the locking block 400 is locked and matched with the handle 200, and the handle 200 drives the transmission device to be in a disconnected state. This also enables the transmission to be effectively maintained in either a transmission state or a disconnected state, and will not be described in detail herein.

Further, as shown in fig. 4, the locking block 400 is provided with a clamping groove 430, and the locking block 400 is clamped on the locking plate 300 through the clamping groove 430 to realize the detachable connection between the locking block 400 and the locking plate 300, so that the locking block 400 can be conveniently assembled and disassembled between the locking plates 300.

Further, the lock block 400 may have a first end surface. The clamping groove 430 has a bayonet penetrating to the first end surface along the fastening direction, the first sub-locking groove 410 has a first opening penetrating to the first end surface along the fastening direction, and the second sub-locking groove 420 has a second opening penetrating to the first end surface along the fastening direction. This card is established the direction and is the direction that jam block 400 located lock plate 300 through draw-in groove 430 card, and this kind of setting down jam block 400 can carry out the dismouting according to following mode:

the locking block 400 may not be installed at an initial stage, and when the handle 200 is rotated to the first angular position, the manipulation knob 220 is moved such that the locking head 221 is inserted into the first positioning hole 310, thereby completing the pre-fixing of the handle 200.

Then, the locking block 400 is installed, and since the first opening, the second opening and the bayonet are all disposed on the first end surface, when the clamping groove 430 is used for clamping the locking plate 300, the first sub-locking groove 410 is also used for completing the locking matching of the locking head 221.

Similarly, if the locking piece 400 needs to be removed next, the first sub-locking groove 410 is unlocked from the locking head 221 while the locking plate 300 is separated from the locking groove 430, and the locking piece 400 can be taken out of the locking plate 300 directly.

If the transmission needs to be switched to the off state, the handle 200 is rotated to the second angular position and operated in a manner similar to that described above, and will not be described in detail herein. It can be seen that, this arrangement can improve the efficiency of detaching the lock block 400 from the lock plate 300, and simplify the operation.

Furthermore, the locking direction of the locking block 400 can be set along the gravity direction, which further facilitates the detachment between the locking block 400 and the locking plate 300.

Further, the locking block 400 is further provided with a fixing structure 440, and the locking block 400 can be fixed to the apparatus main body 100, specifically, the locking plate 300 of the apparatus main body 100, by the fixing structure 440. For example, the fixing structural member 440 is a claw and is disposed on the slot 430, and when the locking block 400 is fastened on the locking plate 300, the claw can be fastened on the locking plate 300 to complete the fixing; or the fixing structure 440 may be a magnetic attraction member capable of attracting the locking plate 300. The fixing structure 440 can fix the locking block 400 at the locking position, and prevent the locking block from separating from the locking plate 300, so as to ensure that the handle 200 is effectively fixed at the current position, and further ensure that the transmission device is effectively kept in a transmission state or a disconnection state.

In a more specific embodiment, the fixation structure 440 may be provided as a set screw. The locking piece 400 is provided with a first clamping plate and a second clamping plate which are positioned on two opposite sides of a clamping groove 430, a first sub-locking groove 410 and a second sub-locking groove 420 can be arranged on the first clamping plate, a fastening threaded hole can be arranged on the second clamping plate, the fastening threaded hole is communicated with the clamping groove 430, and a fastening screw is in threaded connection with the fastening threaded hole. In the case that the locking block 400 is caught by the locking plate 300, the set screw may be screwed into the catching groove 430 until the locking plate 300 is pressed, so that the locking block 400 is fixed to the locking plate 300.

Further, it is to be noted that the rocker 210 and the handle 220 are connected. The through hole 211 may be a threaded hole, the handle 220 is in threaded connection with the threaded hole, the handle 220 may perform a spiral motion relative to the rocker 210, and the lock head 221 may move along with the spiral motion of the handle 220, so as to achieve locking engagement or unlocking engagement between the handle 200 and the lock block 400 or the lock plate 300, respectively.

In other embodiments, the via hole 211 may be a smooth surface hole, and an elastic member 500, such as a spring, a rubber pad, etc., may be disposed in the via hole 211. The portion of the handle 220 passing through the through hole 211 is provided with a stopping portion 222, for example, the stopping portion 222 is provided as a stopping ring or a stopping block. The stopping portion 222 is elastically matched with the elastic member 500, for example, a spring, the elastic member 500 can be sleeved on the handle 220, and the elastic member 500 and the stopping portion 222 are sequentially disposed along a direction close to the lock head 221.

With this arrangement, the elastic member 500 can drive the locking head 221 to extend into the locking groove. For example, when the locking engagement between the locking piece 400 and the handle 200 needs to be released, the handle 220 is pulled out in a direction away from the locking plate 300, so that the handle 220 is separated from the first sub-locking groove 410 and the first positioning hole 310, or separated from the second sub-locking groove 420 and the second positioning hole 320, so that the handle 220 can be rotated again, and the elastic member 500 is in a compressed state.

When the locking block 400 and the handle 200 need to be locked and matched again, the handle 200 is rotated to the first angle position, then the handle 220 is released, and under the elastic force of the elastic member 500, the handle 220 is driven to move towards the direction close to the locking plate 300 through the elastic matching of the stopping portion 222, so that the locking head 221 protrudes into the first sub-locking groove 410 and the first positioning hole 310 again, so as to complete the locking and matching. If the handle 200 is required to complete the locking engagement at the second angular position, the resilient engagement of the resilient member 500 and the stopping portion 222 can also be achieved.

Further, the end of the locking head 221 may be chamfered or rounded to facilitate insertion of the first sub-locking groove 410 and the first positioning hole 310, or to facilitate insertion of the second sub-locking groove 420 and the second positioning hole 320.

In a more specific embodiment, the apparatus body 100 includes a housing 130, a drive shaft 110, and a clutch 120. The housing 130 may cover and protect the components inside the device body 100, specifically, the transmission shaft 110 is rotatably disposed in the housing 130, and the clutch 120 is disposed in the housing 130.
