Abstract
The utility model discloses a zero position mechanical self-locking apparatus for linkage console so disposed that the lower end of a handle is fixedly provided with a hollow external control stick, an internal control stick which is capable of sliding being inserted to the external control stick with two ends extending out, the handle being provided with a lever, for which a rotating shaft serves as the fulcrum, the handle being provided with a button for driving the upper end of the lever, the lower end of the lever being connected to the upper end of the internal control stick, the upper end of the internal control stick and upper end of the external control stick being provided with a return spring therebetween, a zero plate being arrange below the external control stick, the zero plate being provided with a zero hole for the insertion of the lower end of the internal control stick so as to realize zero position self locking, the zero plate being provided with a zero self-locking contact thereon. The linkage between the zero position mechanical self-locking apparatus for linkage console and the electric contact can realize zero position self lock characterized by high reliability.
Description
Technical field
The utility model relates to a kind of coupled control table zero-bit mechanical self-locking device.
Technical background
The handle of original coupled control table has only electric auto-lock function, does not have the mechanical self-latching function, the rate of fault height, and safety coefficient is low, and working life is short.Therefore, be necessary the handle of existing coupled control table is improved.
The model utility content
Technical problem to be solved in the utility model is to propose a kind of coupled control table zero-bit mechanical self-locking device, and this coupled control table zero-bit mechanical self-locking device and electrical contact are chain, realizes the zero-bit auto-lock function, the reliability height.
Technical solution of the present utility model is as follows:
A kind of coupled control table zero-bit mechanical self-locking device is fixed with the outer operating handle of hollow in the lower end of handle, slidably in operating handle be inserted in the outer operating stem, and stretch out at two ends;
Being provided with in the handle with the rotating shaft is the lever of fulcrum, and handle is provided with the button that is used for the driving lever upper end, and the lower end of lever is connected with the upper end of interior operating handle; Be provided with return spring between the upper end of interior operating handle and the upper end of outer operating handle;
The below of outer operating handle is provided with a zinc coat steel plate, and zinc coat steel plate is provided with the interior end, operating handle lower end of a confession and inserts to realize the zero-bit hole of zero-bit self-locking.
Described zinc coat steel plate is provided with zero-bit self-locking contact.
Beneficial effect:
Coupled control table zero-bit mechanical self-locking device of the present utility model is provided with button on handle, based on lever principle, operating handle action in driving, with zinc coat steel plate to cooperating, realized the mechanical self-latching function.And be provided with zero-bit self-locking contact by lower end at interior operating handle, be used for compatible electric self-locking.Because mechanical self-latching is more reliable more than electric self-locking, therefore, the reliability of self-locking of the present utility model is higher, has improved the safety coefficient of existing equipment.In addition, handle of the present utility model makes full use of, and has also improved efficiency of equipment thus.
Description of drawings
Fig. 1 is embodiment 1 a structural drawing.
Label declaration: 1-handle, 2-button, 3-lever, 4-rotating shaft, the rotating shaft of 5-button, 6-return spring, 7-handle side cover, 8-tightly locks screw, the outer operating handle of 9-, 10-top slide block, 11-top slide block setting sleeve, 12-zero-bit self-locking contact, 13-bottom slide block, operating handle in the 13-zinc coat steel plate, 14-, 15-bottom slide block.
Embodiment
Below with reference to figure and specific implementation process the utility model is described in further details:
Embodiment 1:
As shown in Figure 1, a kind of coupled control table zero-bit mechanical self-locking device is fixed with the outer operating handle of hollow in the lower end of handle, slidably in operating handle be inserted in the outer operating stem, and stretch out at two ends;
Being provided with in the handle with the rotating shaft is the lever of fulcrum, and handle is provided with the button that is used for the driving lever upper end, and the lower end of lever is connected with the upper end of interior operating handle; Be provided with return spring between the upper end of interior operating handle and the upper end of outer operating handle;
The below of outer operating handle is provided with a zinc coat steel plate, and zinc coat steel plate is provided with the zero-bit hole that the insertion of end, operating handle lower end realizes the zero-bit self-locking in the confession.The top slide block setting sleeve is arranged on the outer operating handle, plays spacing effect, and operating handle rising or decline scope are excessive in preventing.Top slide block and bottom slide block are arranged on the interior operating handle.
Described zinc coat steel plate is provided with zero-bit self-locking contact.
Working procedure explanation: when operator hold operating grip, press the button, the driving lever of button pressed downwards driving lever, lever rotates around the axis and mentions interior operating handle, interior operating handle rises and leaves zinc coat steel plate, has removed self-locking state this moment, and operating mechanism can drive the electrical contact switching that joint action table is associated, the operator can realize the operations such as startup, speed governing, commutation and braking of motor under released state.
When handle was got back to vertical position and release button, interior operating handle inserted under the effect of return spring in the zero-bit hole in the zinc coat steel plate, realizes the zero-bit auto-lock function.
Claims (2)
1. a coupled control table zero-bit mechanical self-locking device is characterized in that, is fixed with the outer operating handle of hollow in the lower end of handle, and slidably interior operating handle is inserted in the outer operating stem, and stretch out at two ends;
Being provided with in the handle with the rotating shaft is the lever of fulcrum, and handle is provided with the button that is used for the driving lever upper end, and the lower end of lever is connected with the upper end of interior operating handle; Be provided with return spring between the upper end of interior operating handle and the upper end of outer operating handle;
The below of outer operating handle is provided with a zinc coat steel plate, and zinc coat steel plate is provided with the interior end, operating handle lower end of a confession and inserts to realize the zero-bit hole of zero-bit self-locking.
2. coupled control table zero-bit mechanical self-locking device according to claim 1 is characterized in that described zinc coat steel plate is provided with zero-bit self-locking contact.
