Detailed Description
The switch control device of the present invention includes a control member, a link rotating mechanism 5 and a transmission mechanism 6, as shown in fig. 2, which is a schematic diagram of an installation position of the present invention, the drawer 3 includes a front panel 3A and a side panel 3B, and the switch 2 is disposed in the drawer 3 and keeps a certain distance from the front panel 3A and the side panel 3B. The connecting rod rotating mechanism 5 of the invention is arranged on the drawer front panel 3A; one end of the transmission mechanism 6 is connected with the connecting rod rotating mechanism 5, and the other end of the transmission mechanism 6 is connected with the switch 2. Fig. 3 is a schematic view of the present invention, where the control member is connected to the link rotation mechanism 5, and controls the rotation of the transmission mechanism 6 through the rotation of the link rotation mechanism 5, so as to control the switch 2.
As shown in fig. 4, the link rotation mechanism 5 according to the present invention includes a main rotation lever 51, a sub rotation lever 52, a first sub link 53 and a second sub link 54, wherein the main rotation lever 51 is hinged to a first shaft 55 with the first sub link 53, the main rotation lever 51 is hinged to a fourth shaft 58 with the second sub link 54, the sub rotation lever 52 is hinged to a second shaft 56 with the first sub link 53, and the sub rotation lever 52 is hinged to a third shaft 57 with the second sub link 54. The first shaft 55, the second shaft 56, the third shaft 57, and the fourth shaft 58 are connected to form a parallelogram. The main rotating rod 51 is provided with a first connecting hole 5A, the auxiliary rotating rod 52 is provided with a second connecting hole 5B, and a connecting line between the first connecting hole 5A and the second connecting hole 5B is parallel to a connecting line between the first shaft 55 and the second shaft 56. The master rotation lever 51 is further provided with a first rotation means, the slave rotation lever 52 is further provided with a second rotation means, the first rotation means coincides with the first connection hole 5A, and the second rotation means coincides with the second connection hole 5B. The control element of the invention is in driving connection with the first connecting hole 5A, and the transmission mechanism 6 is in driving connection with the second connecting hole 5B. So set up, when the operator rotates the control piece outside the drawer, the rotation of the control piece makes main swivelling lever 51 begin synchronous rotation with first rotary device as the axle, because the effect of four-bar linkage is rotatory with second rotary device as the axle from swivelling lever 52, the angular velocity that main swivelling lever 51 rotated is the same with the angular velocity of rotation of from swivelling lever 52, will rotate from swivelling lever 52 and transmit the rotation to switch 2 through drive mechanism 6, realizes the control to switch 2. The main rotating rod 51 and the auxiliary rotating rod 52 of the invention always do not move the rotating shaft when rotating, thereby ensuring the stability and the functionality of the structure.
The control element is a handle 4, the handle 4 can be inserted into the first connecting hole 5A, and the external contour of the handle 4 is matched with the first connecting hole 5A. Specifically, the handle 4 is a square tube. So arranged, torque of the handle 4 is easily transferred to the transmission mechanism 6 through the link rotation mechanism 5.
Specifically, the link rotation mechanism 5 is rotatably connected to the front panel 3A by a first rotation means and a second rotation means. Preferably, the rotating device is a rolling bearing. The connecting rod rotating mechanism 5 is connected with an inner ring of the rolling bearing, and the front panel 3A is connected with an outer ring of the rolling bearing.
Specifically, the front panel 3A is provided with a through hole corresponding to the second connection hole 5B, and the transmission mechanism 6 penetrates through the through hole and is connected to the link rotation mechanism 5.
Specifically, the transmission mechanism 6 includes a transmission rod 61 and a switch connector 62, one end of the transmission rod 61 is insertable into the second connection hole 5B, the external contour of the transmission rod 61 matches with the second connection hole 5B, and the other end of the transmission rod 61 is connected to the switch connector 62. The switch connector 62 is connected to the switch 2. Specifically, the transmission rod 61 is a square tube.
The invention also comprises a stroke feedback device 7, wherein the stroke feedback device 7 comprises a connecting rod and a spring, the spring is arranged on the connecting rod, one end of the connecting rod is connected with the connecting rod rotating mechanism 5, and the other end of the connecting rod is movably connected with the drawer side plate 3B. In particular, the links may be connected with the first and/or second auxiliary links 53, 54. As shown in fig. 3, the link rotation mechanism 5 is in an initial state at this time, and the springs are not compressed. The link lever rotating mechanism 5 continues to rotate clockwise, the link lever of the travel feedback device 7 moves rightwards, and the spring is extruded with the drawer side plate 3B to generate elastic force so as to remind an operator of opening the switch 2. As shown in fig. 4, at this time, the switch 2 has been opened, the link rotation mechanism 5 stops rotating clockwise, and the spring force of the spring has reached the maximum, but the spring force of the spring is still smaller than the locking force of the switch 2, thereby ensuring the normal operation of the switch 2. When the switch 2 needs to be turned off, an operator rotates the handle 4 anticlockwise from the state shown in fig. 4, the elasticity of the spring provides assistance for turning off the switch 2, and the connecting rod rotating mechanism 5 rotates anticlockwise to an initial state, so that complete on-off cycle of the switch 2 is realized.
When other switches 2 are selected, the positions of the switches in the drawer may change, when the prior art deals with the situation, the positions need to be calculated according to the position relation, and then parts are machined, if machining is not accurate enough, the problem that the switches cannot be used still occurs, the working procedure is complicated, and the yield is low. The invention can easily cope with different switches 2by adjusting the distance between the main rotating rod 51 and the auxiliary rotating rod 52 between the connecting rod rotating mechanisms 5 and the length of the transmission mechanism 6 through the mutual matching among the connecting rod rotating mechanisms 5, the transmission mechanism 6 and the control parts.
The connecting rod rotating mechanism 5, the transmission mechanism 6 and the control part can be made into modularized components, and only proper components are needed to be assembled and combined when the novel combined type multifunctional combined. For example, rotating rods and auxiliary connecting rods with different lengths are manufactured in advance, and different components are selected for combination when the novel rotary type rotary machine is used. If the auxiliary connecting rod with the proper length is not provided, the proper assembly can be obtained by processing the length of the auxiliary connecting rod without precise calculation, and a large amount of working hours are saved. For example, the transmission mechanism 6, the switch connector 62 can be adapted to different types of switches, and the transmission rod 61 with a proper length is combined with the switch connector, so that the design is far more adaptive than the prior art. The modularized combination ensures that each component has definite position and connection relation, has the function of limiting and guiding, and has higher stability compared with the traditional scheme.
