[0036] Please refer to Figure 1 and Figure 2 A lever connector in a preferred embodiment of the present utility model includes a socket body 100 and a lever assist member 200 .

[0037] A limiting structure 110 is provided on the front side of the socket body 100; the lever assist member 200 has an idle state and a working state, and the lever assist member 200 is rotatably mounted on the socket body 100 to realize the rotation switching of the lever assist member 200 between the idle state and the working state. The lever assist member 200 in the idle state can rotate in a first direction to pass over the limiting structure 110 to reach the working state; Figure 6As shown, the first direction is the counterclockwise direction in the figure, and the second direction is the clockwise direction in the figure. The limiting structure 110 is used to block and limit the rotation of the lever assist member 200 in the working state along the second direction, and the first direction and the second direction are opposite directions; and the limiting structure 110 can move to release the blocking and limiting of the lever assist member 200 in the working state, so that the lever assist member 200 in the working state can rotate along the second direction to the idle state; the lever assist member 200 has an operating part 210 for hand contact operation, and the operating part 210 has a plurality of reinforcing ribs 220, and the width direction of the reinforcing ribs 220 is parallel to the rotation axis of the lever assist member 200, that is, the force applied to the operating part 210 to drive the lever assist member 200 to rotate is parallel to the reinforcing ribs 220, so that the reinforcing ribs 220 and the force are in the same direction, which can effectively strengthen the structural strength of the operating part 210. Specifically, the width direction of the reinforcing ribs 220 is Figure 1 left and right direction.

[0038] The utility model provides a lever connector, which utilizes the rotational activity of the lever assisting member 200 to realize the rotational switching between the idle state and the working state, and utilizes the limiting structure 110 to block and limit the rotation of the lever assisting member 200 in the working state along the second direction, so that the lever assisting member 200 remains in the working state. When the limit needs to be released, the limiting structure 110 can be operated to move, and the operation is simple; the multiple reinforcing ribs 220 on the operating part 210 are utilized to improve the structural strength of the operating part 210, so that the operating part, which is the part directly subjected to force, is structurally reinforced, thereby improving the structural strength and service life; and the width direction of the reinforcing ribs 220 is parallel to the rotation axis of the lever assisting member 200, and the direction of the reinforcing ribs is consistent with the direction of force applied to drive the rotational activity of the lever assisting member 200, which greatly enhances the strength of the lever assisting member in the force direction, and the design is more scientific and reasonable; compared with the utility model, the utility model has the advantages of simple structure, simple operation, simple structure ... Figure 7 In the prior art shown, the length direction of the reinforcing rib 101 is parallel to the rotation axis of the lever assist member 200. The design of the reinforcing rib 220 in the embodiment of the utility model can more directly resist the force driving the lever assist member 200 to rotate, making the structural reinforcement effect of the reinforcing rib 220 more obvious.

[0039] Reference Figure 3 and Figure 4 In some embodiments of the present invention, the operating part 210 includes a horizontal plate 211 and a vertical plate 212. The vertical plate 212 is disposed on the side of the horizontal plate 211 facing the limiting structure 110. The reinforcing ribs 220 are connected between the vertical plate 212 and the horizontal plate 211, thereby reinforcing the horizontal plate 211 and the vertical plate 212 so as to effectively reduce deformation and damage when they are subjected to the force of the rotation activity of the driving lever assist member 200. Figure 7In the prior art shown in the figure, when the finger operates the operating part 210, the contact surface is small and the finger feels painful. The vertical plate 212 of the embodiment of the utility model can increase the contact area during operation. Figure 2 The lever assist member 200 in the working state shown needs to be switched to Figure 1 In the idle state shown, the vertical plate 212 can be moved upward by fingers to switch the state. The contact area between the finger and the operating part 210 is large, and the pressure becomes smaller under the same force, which increases the comfort of operation and facilitates the operation of the user.

[0040] Reference Figure 3 and Figure 4 In a further embodiment of the utility model, the reinforcing rib 220 has an inclined surface 221, one end of the inclined surface 221 is connected to the vertical plate 212, and the other end is connected to the horizontal plate 211, thereby reducing the use of materials and making the connection transition between the horizontal plate 211 and the vertical plate 212 smoother; the inclined surface 221 is provided with a plurality of friction protrusions 222, so that it is convenient for fingers to apply force when the operating part 210 moves counterclockwise.

[0041] Reference Figure 1 and Figure 2 In a further embodiment of the utility model, the limiting structure 110 is an elastic locking tongue, one end of which is connected to the socket body 100, and the other end is elastically movable and is provided with a limiting protrusion 111 protruding outward. Specifically, the bottom of the elastic locking tongue is connected to the socket body 100, and the upper end is a free end that is elastically movable. The limiting protrusion 111 is provided at the upper end of the elastic locking tongue and protrudes forward. The limiting protrusion 111 is used to block and limit the lever assist member 200 in the working state. The upper and lower end edges of the limiting protrusion 111 are chamfered to facilitate deformation by the operating part 210. When the lever assist member 200 in the idle state needs to be switched to the working state, the operating part 210 rotates to press the limiting protrusion 111 to deform backward until the operating part 210 passes over the limiting protrusion 111, and the limiting protrusion 111 elastically resets to limit the operating part 210, that is, the limiting position is achieved. Figure 2 When the lever assist member 200 in the working state needs to be switched to the idle state, the limit protrusion 111 is pressed backward and the operating portion 210 is rotated upward.

[0042] Reference Figure 1 In a further embodiment of the present invention, there is a gap between the rear side of the elastic locking tongue and the socket body 100, and the left and right sides of the elastic locking tongue and the socket body 100 form an avoidance groove 112, which makes the elastic locking tongue more easily deformed. Figure 8As shown in the figure, the rear part and both sides of the lock tongue 102 of the prior art are mostly connected to the socket body 100, and the structural strength is too large. When separating, a large force is required to deform the lock tongue 102, and the user's comfort in operation is poor. The left and right sides and the rear side of the elastic lock tongue of the present application are not connected to the socket body 100, and the elasticity is better. The elastic lock tongue can be separated from the operating part 210 with less force, and it is more convenient to use.

[0043] Reference Figures 3 to 5 In some embodiments of the utility model, a rotating connecting arm 230 is provided on the left and right sides of the operating part 210, and a rotating shaft 120 is provided on the left and right sides of the socket body 100. The rotating connecting arm 230 is provided with a rotating hole 231 which is sleeved on the corresponding side rotating shaft 120, so that the rotating connection of the lever assist member 200 is realized through the cooperation of the rotating shaft 120 and the rotating hole 231.

[0044] Reference Figures 3 to 5 In a further embodiment of the utility model, a radial protrusion 121 is provided at the outer end of the rotating shaft 120, and a notch 232 is provided at the rotating hole 231 for the radial protrusion 121 to pass through. The radial protrusion 121 passes through the notch 232 and is arranged at the outer side of the rotating hole 231. The radial protrusion 121 plays a certain axial limiting role on the rotating connecting arm 230. Only when the notch 232 is completely aligned with the radial protrusion 121, the radial protrusion 121 will lose the axial limiting effect. It can be understood that, in the idle state and the working state, the notch 232 is not aligned with the radial protrusion 121, that is, at least in the idle state and the working state, the radial protrusion 121 has an axial limiting effect on the rotating connecting arm 230, so that the rotation connection of the rotating connecting arm 230 is more stable.

[0045] Reference Figures 3 to 5 In a further embodiment of the utility model, the rotating connecting arm 230 is provided with an inwardly recessed limiting arc groove 233 on the outer side of the rotating hole 231, and the outer side of the rotating hole 231 is the side facing away from the socket body 100; the limiting arc groove 233 has two end walls 234, and the radial protrusion 121 is embedded in the limiting arc groove 233 and rotates between the two end walls 234. The two end walls 234 are used to limit the rotational activity range of the radial protrusion 121, that is, to limit the rotational activity range of the lever assisting member 200, so as to avoid the lever assisting member 200 from having an excessively large rotational activity range.

[0046] Reference Figure 6In a further embodiment of the utility model, two radial protrusions 121 are arranged at intervals. When the lever assist member 200 is in an idle state, one of the radial protrusions 121 is in contact with the end wall 234, so that the idle state of the lever assist member 200 is positioned and limited. That is, when the lever assist member 200 rotates from the working state to the idle state, it only needs to be rotated until the radial protrusion 121 is in contact with the end wall 234, which indicates that it is in place, and the operation is simple.

[0047] Reference Figure 6 In a further embodiment of the utility model, limiting ears 130 are provided on the left and right sides of the socket body 100, and the limiting ears 130 are used to block the rotation of the rotatable connecting arm 230 in the idle state along the second direction, so as to avoid that when the rotatable connecting arm 230 in the idle state is driven by the force to rotate along the second direction, the force is all concentrated on the radial protrusion 121, thereby avoiding damage to the radial protrusion 121. The limiting ears 130 have a large area and can effectively unload the force.

[0048] like Figure 4 As shown, the limiting ear 130 is provided with a socket 131, and the rotating connecting arm 230 is provided with a guide groove 235, one end of the guide groove 235 is provided with an entrance, and the other end is retracted toward the rotation center of the rotating connecting arm 230; when in the idle state, the entrance of the guide groove 235 is aligned with the socket 131, and protrusions are provided on the left and right sides of the plug, and the protrusions can pass through the socket 131 and the entrance into the guide groove 235, and then the rotating connecting arm 230 is rotated to switch the rotating connecting arm 230 to the working state, and during the rotation process, the guide groove 235 groove arm is retracted toward the rotation center of the rotating connecting arm 230, thereby driving the protrusion to approach the rotation center of the rotating connecting arm 230, so that the plug and the socket body are gradually approached to achieve plug-in, and due to the effect of the limiting structure 110, the two are kept in a stable plug-in state.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
