[0054] The detachable instrument device 100 of the present application is suitable for a main control room, wherein a mounting hole 211 is provided on a panel table 210 of the main control room.

[0055] Referring to Figures 1-3, Figure 1 shows a schematic diagram of the structure of a detachable meter device 100 in an embodiment of the present application, Figure 2 is a schematic diagram of the structure of the detachable meter device in Figure 1 from another perspective, and Figure 3 is an exploded view of the detachable meter device in Figure 1. The detachable meter device 100 provided in an embodiment of the present application includes: an operating mechanism 110, a signal transmission mechanism 120, and an elastic abutment component 130.

[0056] Refer to FIG3 , which is an exploded view of the detachable instrument device, and is also a schematic diagram of the connector 111, the operating assembly 112, and the disk table 210 before assembly. Please refer to FIG6 for the structure after the operating assembly 112 is connected to the disk table 210. In the above-mentioned detachable instrument device 100, the operating mechanism 110 includes a connector 111 and an operating assembly 112 connected to each other. The connector 111 is inserted into the mounting hole 211, and the outer wall of the connector 111 has a connecting countersunk hole 113. The operating mechanism 110 is connected to the disk table 210. The signal transmission mechanism 120 is located on the side of the disk table 210 away from the operating assembly 112. The signal transmission mechanism 120 includes a connector 121 and a signal transmission assembly 122. The signal transmission assembly 122 has a countersunk groove 123 on one end surface close to the disk table 210. The connector 121 is arranged in the countersunk groove 123 and connected to the signal transmission assembly 122. The connecting member 111 can be inserted into the sink groove 123 and detachably connected to the connecting head 121 . The elastic abutment assembly 130 is disposed on the side wall of the sink groove 123 and is adapted to the connecting counterbore 113 .

[0057] During the installation of the above-mentioned detachable instrument device 100, firstly, the connecting member 111 is inserted into the installation hole 211 and the operating mechanism 110 is connected to the disk table 210, and the signal transmission mechanism 120 is held and the connecting member 111 is inserted into the sink groove 123, so that the connecting member 111 is connected to the connector 121. In the process of inserting the connecting member 111 into the sink groove 123, due to the elastic force of the elastic abutment component 130, the elastic abutment component 130 always slides with the side wall of the connecting member 111, and then the elastic abutment component 130 partially enters the connecting sink hole 113 and adapts to the connecting sink hole 113. At this time, the operating mechanism 110 and the signal transmission mechanism 120 are relatively fixed, so that the signal transmission mechanism 120 can be fixed relative to the disk table 210, and the signal transmission mechanism 120 is connected with other components to be controlled. Thereby, the operator can issue control instructions to the component to be controlled by operating the operating mechanism 110. If the operating mechanism 110 needs to be separated from the signal transmission mechanism 120, it is only necessary to hold the signal transmission mechanism 120 and drive the signal transmission mechanism 120 away from the operating mechanism 110. At this time, the elastic abutment assembly 130 disengages from the connecting countersunk hole 113. During the process of the signal transmission mechanism 120 disengaging from the operating mechanism 110, the elastic abutment assembly 130 always slides with the side wall of the connecting member 111. Then the signal transmission mechanism 120 disengages from the operating mechanism 110 until it is completely disengaged, thereby realizing the detachable connection between the signal transmission mechanism 120 and the operating mechanism 110. The connecting member 111 is passed through the mounting hole 211, so that the detachable instrument device 100 can adapt to the size of the smaller mounting hole 211 on the main control room panel 210.

[0058] 1-6, in one embodiment, the inner wall of the sink 123 is provided with an abutment hole 124. The elastic abutment component 130 is a ball screw, which is disposed in the abutment hole 124, and the ball of the ball screw faces the connection sink hole 113, so that the ball of the ball screw and the connection sink hole 113 can be engaged or disengaged by the ball screw, thereby realizing a detachable connection between the signal transmission mechanism 120 and the operating mechanism 110.

[0059] Specifically, the ball screw includes a screw (not shown), an elastic member (not shown) and a bead (not shown). A bead groove (not shown) is provided at one end of the screw, and a side wall at the notch of the bead groove has an annular protrusion (not shown), which protrudes toward the axis of the bead groove. One end of the elastic member is connected to the bottom wall of the bead groove, and the other end is connected to the bead. The bead abuts against one side of the annular protrusion close to the bead groove, and the bead part protrudes out of the bead groove, and the bead faces the connection countersunk hole 113. In the process of inserting the connecting member 111 into the sink groove 123, due to the elastic force of the elastic member, the bead body always abuts against the side wall of the connecting member 111, and then the bead body part enters the connecting sink hole 113 and adapts to the connecting sink hole 113. At this time, the positions of the operating mechanism 110 and the signal transmission mechanism 120 are relatively fixed, so that the signal transmission mechanism 120 can be fixed relative to the disk table 210, and the signal transmission mechanism 120 is connected with other components to be controlled, so that the operator can send a control instruction to the component to be controlled by operating the operating mechanism 110. If the operating mechanism 110 needs to be separated from the signal transmission mechanism 120, it is only necessary to hold the signal transmission mechanism 120 and drive the signal transmission mechanism 120 away from the operating mechanism 110. At this time, the bead is separated from the connection countersunk hole 113. In the process of the signal transmission mechanism 120 being separated from the operating mechanism 110, due to the elastic force of the elastic member, the bead is always in contact with the side wall of the connecting member 111. Then, the signal transmission mechanism 120 is completely separated from the operating mechanism 110, thereby realizing the detachable connection between the signal transmission mechanism 120 and the operating mechanism 110. The specific structure of the ball screw refers to the prior art, and the specific structure is not reflected in the drawings.

[0060] In another embodiment, the structure of the elastic abutment assembly 130 includes an elastic member and a bead, the abutment hole 124 is a blind hole, the side wall at the hole mouth of the abutment hole 124 has an annular protrusion, the annular protrusion protrudes toward the axis of the abutment hole 124, one end of the elastic member is connected to the bottom wall of the abutment hole 124, and the other end is connected to the bead, the bead abuts against one side of the annular protrusion close to the bead groove, and the bead part protrudes out of the abutment hole 124, so the specific structure of the elastic abutment assembly 130 is not limited.

[0061] In one embodiment, the abutment hole 124 is a threaded through hole, and a mating groove is provided at one end of the ball screw away from the connecting countersunk hole 113. The external thread of the screw cooperates with the internal thread of the inner wall of the abutment hole 124. The mating groove is used to cooperate with a rotating tool. The ball screw can be rotated by cooperating with the mating groove through a rotating tool such as a wrench or a screwdriver, so that the ball screw can be screwed into the abutment hole 124. There is no need to process the abutment hole 124 in the countersunk groove 123 and install the elastic abutment assembly 130, which makes the installation of the elastic abutment assembly more convenient.

[0062] Specifically, the elastic member is a spring, and may also be other forms of elastic members, which are not limited here.

[0063] Specifically, the ball-end screw is a hexagon socket ball-end screw, and may also be other forms of ball-end screws, which are not limited here.

[0064] Referring to FIGS. 1-6, in one embodiment, the detachable instrument device 100 further includes a threaded clamping member 140, the inner wall of the sink 123 is provided with a first fixing hole 125, the inner wall of the first fixing hole 125 has an internal thread, the threaded clamping member 140 has an external thread, the threaded clamping member 140 is passed through the first fixing hole 125, the external thread of the threaded clamping member 140 is matched with the internal thread of the first fixing hole 125, the threaded clamping member 140 can be clamped or released with the connecting member 111, after the elastic abutment assembly 130 is clamped and matched with the connecting sink hole 113, the operating mechanism 110 and the signal transmission mechanism 120 are relatively fixed at this time, and then the threaded clamping member 140 is tightened. The clamping member 140 enables the threaded clamping member 140 to be clamped with the connecting member 111 or to abut against the outer wall of the connecting member 111, so that the connecting member 111 is fixed in the recess 123. When the operating mechanism 110 needs to be separated from the signal transmission mechanism 120, the threaded clamping member 140 is rotated in the opposite direction to release the clamping member 140 from the connecting member 111 or to release the abutment against the outer wall of the connecting member 111. Then, the signal transmission mechanism 120 is held and driven away from the operating mechanism 110, and the signal transmission mechanism 120 is separated from the operating mechanism 110, thereby achieving stable connection and disassembly of the signal transmission mechanism 120 and the operating mechanism 110.

[0065] 1-6, in one embodiment, the outer wall of the connecting member 111 is provided with a second fixing hole 114. The threaded clamping member 140 can partially extend into the second fixing hole 114, so that the threaded clamping member 140 can relatively stably fix the connecting member 111 in the sinking groove 123 by extending the threaded clamping member 140 into the second fixing hole 114, and prevent the connecting member 111 from slipping out of the sinking groove 123 due to the threaded clamping member 140 only abutting against the outer wall of the connecting member 111.

[0066] Referring to Figure 4, specifically, the threaded clamping member 140 includes a threaded member 141 and a rotating member 142. The threaded member 141 is connected to one end of the rotating member 142 close to the second fixing hole 114. The threaded member 141 has an external thread. The threaded member 141 is inserted into the first fixing hole 125. The external thread of the threaded member 141 cooperates with the internal thread of the first fixing hole 125. The operator can rotate the rotating member 142 to drive the threaded member 141 to rotate, thereby screwing the threaded member 141 out of the second fixing hole 114 or screwing it into the second fixing hole 114.

[0067] Referring to Fig. 3, Fig. 4 and Fig. 6, in one embodiment, the detachable instrument device 100 includes a fixing nut 150, which is threadedly matched with the outer wall of the connecting member 111, and the disk table 210 is located between the fixing nut 150 and the operating assembly 112. In the process of installing the operating mechanism 110, the connecting member 111 is firstly inserted into the mounting hole 211, and then the fixing nut 150 is threadedly matched with the outer wall of the connecting member 111, so that the disk table 210 is clamped between the fixing nut 150 and the operating assembly 112, so that the operating mechanism 110 is fixed to the disk table 210. If the operating mechanism 110 needs to be removed from the disk table 210, it is only necessary to rotate the fixing nut 150 to release the fixing nut 150 from the connecting member 111, and then the connecting member 111 is removed from the mounting hole 211, thereby realizing the detachable connection between the operating mechanism 110 and the disk table 210, and facilitating the replacement of the operating mechanism 110.

[0068] 5, in one embodiment, the operating assembly 112 includes an operating circuit board 115 and an operating film 116. The operating film 116 is attached to a side of the operating circuit board 115 away from the disk table 210, and a side of the operating circuit board 115 close to the disk table 210 is connected to the connector 111, so that the operating film 116 is attached to the operating circuit board 115, the operating circuit board 115 is connected to the connector 111, the connector 111 is connected to the connector 121, and the connector 121 is connected to the signal transmission assembly 122, so that each key on the operating film 116 is pressed to control the component to be controlled.

[0069] Referring to Figures 7-10, specifically, the operating film 116 is detachably attached to the operating circuit board 115, and the operating film 116 is provided with at least one button, and may also have 2, 3, 4, or 5 buttons, which are not limited here. Therefore, by replacing the operating film 116, the same operating mechanism 110 can have different button functions, so that the detachable instrument device 100 in the present application is suitable for more control scenarios.

[0070] Referring to Figure 5, specifically, the operating component 112 also includes an operating shell 119, an operating circuit board 115 is arranged in the operating shell 119 and connected to the connecting member 111, an operating film 116 is attached to a side of the operating shell 119 away from the connecting member 111 and connected to the operating circuit board 115, and the disk table 210 is located between the fixing nut 150 and the operating shell 119, so as to protect the operating circuit board 115 and provide a fitting position for the operating film 116. The specific operating film 116 is a prior art, and the main form is a film switch, that is, a touch keyboard, and it can also be other forms, which will not be elaborated here.

[0071] Referring to FIGS. 1-6 , in one embodiment, the connector 111 includes a connecting portion 117 and a connecting socket 118 connected to each other. The end of the connecting portion 117 facing away from the connecting socket 118 is connected to the operating component 112. The connecting socket 118 can be inserted into the sink groove 123 and detachably connected to the connecting head 121. The outer wall of the connecting socket 118 has a connecting sink hole 113, so that the operating component 112 is connected to the connecting socket 118 through the connector 111. Through the detachable connection between the connecting socket 118 and the connecting head 121, the detachable connection between the operating mechanism 110 and the signal transmission mechanism 120 is realized, and when the connecting socket 118 is connected to the connecting head 121, signal transmission can be performed. At the same time, the connecting socket 118 is connected to the connecting portion 117, and the connecting head 121 is arranged in the sink groove 123, thereby protecting the metal protrusions on the connecting head 121 for signal transmission. Compared with the connection socket 118 being disposed in the sink 123 , the connection method of the connection head 121 and the connection portion 117 protects the connection head 121 and the connection socket 118 .

[0072] Specifically, the outer wall of the connecting socket 118 has at least one first plane, and the inner wall of the groove 123 has at least one second plane. The first plane corresponds to and adapts to the second plane one by one, thereby guiding the insertion angle of the connecting socket 118 and preventing the connecting socket 118 from being unable to cooperate with the connecting head 121 due to the mismatch in the angle of the connecting socket 118 inserted into the groove 123.

[0073] Specifically, the side wall of the connecting socket 118 has a connecting countersunk hole 113 and a second fixing hole 114, so that after the connecting socket 118 is inserted into the sink groove 123, the bead body cooperates with the connecting countersunk hole 113 on the connecting socket 118, and the threaded clamp 140 cooperates with the second fixing hole 114 on the connecting socket 118, thereby realizing a detachable connection between the operating mechanism 110 and the signal transmission mechanism 120.

[0074] 4 and 5 , in one embodiment, the signal transmission mechanism 120 includes a transmission shell 160 and a transmission circuit board 126. A sink 123 is provided on one end surface of the transmission shell 160 close to the disk table 210. The transmission circuit board 126 is arranged in the transmission shell 160. The end of the connector 121 facing away from the operating component 112 is located in the transmission shell 160 and connected to the transmission circuit board 126.
