Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of travel remote control auxiliary devices, in particular to a travel remote control linkage device. BACKGROUND

[0002] Currently, each travel remote control has two control rods, one control rod moves in four directions of front, back, left and right, controlling the car to run left and right and the trolley to run forward and backward. The other control rod moves in four directions of front, back, left and right, respectively controlling the main hook lifting and the auxiliary hook lifting.

[0003] When two travel remote controls of the same specification are used to lift and hoist, two people generally operate one travel remote control respectively, and some have a lifting command while others do not.

[0034] According to the height of the operating rod, the distance between the stand 102 and the support plate 103 can be adjusted, when adjusting, the pull rod 209 is first pulled to make the insertion rod 206 get rid of the elastic force of the spring 208 and slide out of one of the limiting holes 204 on the sliding rod 201, at this time, since the sliding rod 201 is separated from the limiting hole 204, the support plate 103 is not limited by the sliding rod 201, so that the position of the support plate 103 on the sliding rod 201 can be adjusted, when the adjustment is completed, the pull rod 209 is released, so that the insertion rod 206 is inserted into one of the limiting holes 204 again under the elastic force of the spring 208, at this time, the limiting and fixing of the support plate 103 and the sliding rod 201 can be quickly completed.

[0035] Specifically, the extension structure 3 comprises a fixed groove 304, a circular ring-shaped fixed groove 304 is respectively formed on the outer portion of the two second connecting rods 107, a fixed ring 303 is rotatably connected to the inner portion of the fixed groove 304, a handle sleeve 301 is fixedly connected to the outer portion of the fixed ring 303, a screw rod 302 is fixedly connected to one end of the handle sleeve 301 close to the first connecting rod 106, and the screw rod 302 is screwedly connected with a threaded groove 305 formed in the inner portion of the first connecting rod 106;

[0036] When the positions of the two rotating sleeves 108 are adjusted, the user only needs to hold the handle sleeve 301 and then rotate the handle sleeve 301. Since the handle sleeve 301 is rotationally connected with the second connecting rod 107 through the fixing ring 303 and the fixing groove 304, the handle sleeve 301 will not fall off during the rotation. Since the screw rod 302 fixed at the end of the handle sleeve 301 is threadedly connected with the first connecting rod 106 through the threaded groove 305, when the handle sleeve 301 is rotated, the screw rod 302 is also driven to rotate, so that the displacement between the first connecting rod 106 and the second connecting rod 107 occurs, thereby quickly realizing the distance between the two rotating sleeves 108, so as to be suitable for the installation of operating rods of different models.

At this time, the positioning block 403 is no longer limited by the horizontal groove and can slide downward, so that the positioning block 403 vertically slides downward until the socket at the bottom end of the positioning block 403 is inserted outside the limiting block 404. At this time, since the upper end of the positioning block 403 is limited by the sliding block 401 and the bottom end is limited by the limiting block 404, the stand 102 cannot rotate with the bottom plate 101 any more, that is, the limiting frame 105 cannot rotate left and right at this time, so that the misoperation when the operating rod is not needed to be operated is avoided, and the operation safety is ensured.
