[0002] The control panel is an important part of the servo system of the land-based weapon system. Its main function is to control the start-up and shutdown of the servo system, and to control the aiming angle and speed of the height and direction of the servo system in a semi-automatic state through the aiming potentiometer.

[0003] For example, a semi-automatic control panel disclosed in the Chinese utility model patent with application number 202322235144.2 includes a connecting base, a base body, a rotating handle assembly and a control panel rotating assembly, wherein the base body is movably arranged on the top surface of the connecting base; the rotating handle assembly is installed on the first rotating member inside the base body through a bearing, and the first rotating member is provided with a first limit member, a first reset member, and a first angle monitoring member; the control panel rotating assembly is installed on the second rotating member inside the base body through a bearing, and the second rotating member is provided with a second limit member, a second reset member, and a second angle monitoring member; the second rotating member is fixed to the connecting base; the first rotating member and the second rotating member are perpendicular to each other. When the automatic gun adjustment function of the above utility model semi-automatic control panel fails, semi-automatic gun adjustment can be achieved through this control panel, and can be applied to simulation training of simulators.

[0004] However, the angle monitoring sensing is mainly realized by the meshing of the signal output gear and the signal acquisition gear. The meshing of the gears itself has a certain gap, and after a long period of operation, the gap may further increase, resulting in error amplification. Utility Model Content

[0005] In order to improve the use accuracy of an operating table, the present application provides an operating table.

[0007] By adopting the above technical solution, when the operator rotates, the corresponding rotating shaft rotates synchronously, and because it is directly connected to the first angle sensor, more accurate angle recognition can be achieved. In order to protect the angle sensor and the rotation path, limit parts are provided at the two end positions of the rotation path of the rotating frame to achieve the limiting function.

[0008] Preferably, the rotating frame surrounds the first angle sensor, the limiting portion is located at the upper part of the shell, and the rotating frame has an edge for contacting with the limiting portion.

[0019] By adopting the above technical solution, no matter to which position the operator rotates, the existence of the arc surface can make the linkage wheel move toward the limiting groove and reset to the middle position.

[0020] Preferably, the outer side of the linkage block has a rubber layer.

[0021] Preferably, both ends of the rotating frame have rotating ends, and the rotating ends are connected to the housing through rotating bearings.

[0023] By adopting the above technical solution, when the operator is rotating, the wiring harness will be located in the wiring groove, and within the range of rotation, the wiring harness can move freely in the opening part without any impact.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. When the operator rotates, the corresponding rotation axis rotates synchronously, and because it is directly connected to the first angle sensor, more accurate angle recognition can be achieved;

DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0035] The present application is further described in detail below in conjunction with the accompanying drawings.

[0036] The present application embodiment discloses a direct-connection operation table. Figure 1 , Figure 2 , including a housing 100 and a base 111, operating hands 112 are rotatably arranged on both sides of the housing 100, and a rotating frame 113 is rotatably connected to the housing 100. The rotating frame 113 has rotating ends 114 on both sides, and the rotating ends 114 are connected to the housing 100 through rotating bearings 115, and the rotating ends 114 are fixedly connected to the operating hands 112. A rotating shaft 116 extends from the rotating end 114 corresponding to one of the operating hands 112, and a first angle sensor 117 is fixedly installed inside the housing 100. In this embodiment, the first angle sensor 117 is a rotary encoder. The rotating shaft 116 is coaxially connected to the first angle sensor 117 to achieve accurate detection.

[0037] Reference Figure 2 , Figure 3 , Figure 4The housing 100 has a limiting portion 120 for contacting and limiting the rotation path of the rotating frame 113. The limiting portion 120 is located on the upper side of the housing 100, and a buffer rubber ring 121 is wrapped around the limiting portion 120. The limiting portion 120 has a receiving groove 122 for the buffer rubber ring 121 to be embedded, and the buffer rubber ring 121 protrudes from the receiving groove 122. The two side edges of the rotating frame 113 have contact inclined surfaces 123 for contacting the buffer rubber ring 121, which can better fit on the buffer rubber ring 121. At the same time, the rotating frame 113 has a top block 124 located on the upper side of the contact inclined surface 123. The top block 124 is used to contact the limiting portion 120, and the top block 124 can ultimately achieve the effect of limiting.

[0038] Reference Figure 5 A first return spring 130 is provided in the shell 100, and a swing block 131 is provided in the shell 100. One end of the first return spring 130 is rotatably connected to the swing block 131, and the other end is rotatably connected to the shell 100. The end of the swing block 131 away from the first return spring 130 is rotatably connected to the shell 100.

[0039] The swing block 131 is used to contact the rotating frame 113 to reset it. The rotating frame 113 has a linkage block 132 placed below, and a limit groove 133 is provided in the middle of the linkage block 132. A linkage wheel 134 is fixed on the swing block 131, and the linkage wheel 134 is embedded in the limit groove 133. The linkage block 132 and the two sides of the limit groove 133 are arc surfaces 135. When the operating hand 112 rotates, the corresponding linkage block 132 will also rotate. At this time, the linkage wheel 134 will slide along the arc surface 135, causing the swing block 131 to move outward, and the first reset spring 130 will be stretched. When resetting later, the first reset spring 130 will make the linkage wheel 134 move into the limit groove 133 again. At the same time, in order to reduce noise and protect the linkage wheel 134 during the movement, a rubber layer is provided on the outer side of the linkage wheel 134 in this embodiment.

[0040] Reference Figure 6 The rotating frame 113 has a wiring groove 140 on one side away from the linkage block 132. One end of the wiring groove 140 is connected to the rotating end 114, and the other end thereof passes downward through the rotating frame 113. The lower side of the wiring groove 140 is in the shape of a trumpet with an expanded diameter. The wiring harness on the operator 112 will pass through the wiring groove 140, and the trumpet-shaped structure can prevent the wiring harness inside the operator 112 from being interfered when the operator 112 rotates.

[0041] In this embodiment, the housing 100 and the base 111 may also be rotatably connected, and a second angle sensor is installed on the base 111, and a second reset spring is also provided. The reset structure is the same as the limit structure, and will not be described in detail here.

[0042] The above specific implementation modes are used to explain the present invention rather than to limit the present invention. Any modification and change made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
