Abstract
The invention relates to a wedge-shaped locking device, an electrical module assembly employing the locking device and a cabinet. The wedge-shaped locking device is arranged on the electrical module. The wedge-shaped locking device comprises a wrench hinged at the front end of a center pole. When an operation part for operating the wrench enables the wrench to rotate, an action part of an eccentric wheel structure of the wrench resists against a force transmission part of the front end of a first wedge-shaped block backwards; under the resistance of the action part of the wrench, a first locking block moves backwards to extrude a floating locking block between the first locking block and a second locking block; the floating locking block moves towards a direction away from the center pole; the electrical module is locked in a guide slot on the cabinet; and after the wrench is in place, the wrench is locked by the locking device. According to the wedge-shaped locking device, locking is realized through wrenching, and the problem that operation is inconvenient due to the fact that a special tool is employed is solved.

The specific embodiment of the rack of the present invention, as shown in Figures 1 to 5, rack includes cabinet and electrical module component, cabinet
Body A is provided with the guide-track groove for extending along the longitudinal direction, and electrical module component includes module matrix B and on module matrix
Wedge lock mechanism, wedge lock mechanism includes the center-pole 4 that extends along the longitudinal direction, sets at the medium position of center-pole 4
There are three screwed holes 41, center-pole 4 is fixed on module matrix by these three screwed holes.The front end edge front and back of center-pole 4
The first wedge 3 is equipped with to guiding movement, the rear end of center-pole 4 is provided with the second wedge 6, in two wedge shapes on center-pole 4
Be provided between block can left and right float floating wedge block 5.
The front end of center-pole 4 passes from the front end of the first wedge 3, and spanner 1 is hinged on the external part of center-pole 4.Pull
Hand 1 includes operating portion 11 and service portion 12, and operating portion 11 is the slab structure for extending along the longitudinal direction, and service portion 12 is with spanner
1 jointed shaft is the eccentric wheel structure of rotating shaft, and spanner passes through afterwards in place eccentric wheel and coordinates realization to lock with the dead point of crossing of force transmitting board.
Force transmitting board 2 is additionally provided between the front end of the first wedge 3 and service portion 12 on center-pole 4, the guiding movement of force transmitting board 2 is assemblied in
On center-pole 4, when pulling spanner 1, the service portion 12 of the eccentric wheel structure of spanner 1 can backward top pressure force transmitting board 2 so that force transmitting board 2
Apply pressure on top surface backward to the first wedge 3.The service portion 12 of the eccentric wheel structure of spanner 1 have respectively with wedge lock fill
The corresponding locking position of released state and locking state put conciliates lock-bit, and locking position is the planar structure with certain length, when
When spanner 1 is in locking position, the planar structure is fitted on the front end face of force transmitting board 2, forms the locating surface of spanner 1, prevents from pulling
Hand 1 is rotated.The locking position of spanner 1 and the distance of rotating shaft are L1, and it is L2 to solve lock-bit and the distance of rotating shaft, spanner 1 from solution lock-bit to
During locking position, the distance that force transmitting board 2 is moved rearwards by can be promoted to be L1-L2.The solution lock-bit of service portion 12 generally arc knot
Structure, is so easy to spanner 1 to rotate.Spanner 1 is provided with top splenium 13 away from the position of its jointed shaft, and the top splenium 13 is by plate shape
Operating portion 11 extend back and form, after spanner 1 is unlocked, be rotated further spanner 1, top splenium 13 can be hung to the first wedge
On 3 outside and the upper surface of guide-track groove cell wall of the top pressure on cabinet, spanner 1 is set to be formed with top splenium 13 and rotating shaft as two
The lever construction of application point.
The guiding movement of second wedge 6 is assemblied on center-pole 4, and being connected with the second wedge 6 can drive the second wedge
The movable adjustable connection mechanism of shape block 6, the adjustable connection mechanism includes coordinating on the rear end of center-pole 4 by screw thread
Adjusting screw 7, in adjusting screw 7 guiding movement turn be furnished with limiting plate 9 of the block in the rear end face of the second wedge 6, dish-shaped bullet
Spring 8 is enclosed within adjusting screw 7, and on the rear end face of limiting plate 9, rear end top pressure is in adjusting screw 7 for the front end top pressure of disk spring 8
Afterbody.The elastic force of disk spring 8 can pass through the active force that 9 pairs of the second wedges 6 of limiting plate apply forward, now the second wedge
Shape block 6 can be moved forward along center-pole 4, to avoid above-mentioned situation, one be assembled in the front side of limiting plate 9 in adjusting screw 7
Individual limit screw cap 71, limit screw cap 71 can block limited block, such limited block just cannot apply forward to second limited block
Active force.
When using, wedge lock mechanism is installed on module matrix by the screwed hole on center-pole 4, now wedge-lock
Then the spanner 1 of tight device inserts the module matrix for being provided with wedge lock mechanism to the guide rail on cabinet in solution lock-bit
In groove, after module inserting in place, spanner 1 is pulled, the service portion 12 of the eccentric wheel structure of spanner 1 can be by force transmitting board 2 pair the
One wedge 3 applies active force backward, is moved rearwards by the first wedge 3, in the effect on the inclined-plane of first, second wedge
Under, move up to the side away from module matrix in middle floating wedge block 5 so that the left surface of floating wedge block 5 is dashed forward
For the outside of first, second wedge, first, second and floating wedge block 5 and the cell wall of guide-track groove coordinate and will be electric
Module is locked.During unblock, opposite direction pulls spanner 1, releases the service portion 12 of spanner 1 and the active force of force transmitting board 2 can be completed
Unblock.Rotating spanner 1 is then proceeded to, the meeting top pressure of top splenium 13 on spanner 1 is now pulled on the front end face of the cell wall of guide-track groove
Hand 1 forms the lever with top splenium 13 and rotating shaft as application point, and module matrix can be subject to driving force backward and depart from and plug together position
Put, now spanner 1 is played and helps the function of pulling out.The locking device pulls spanner 1 and is capable of achieving locking, it is not necessary to specific purpose tool,
It is easy to operate when using.
The wedge lock mechanism on electrical module in the rack of the present invention when in use, by instrument adjusting screw is adjusted
Screw in center-pole 4 on depth can the second wedge 6 be made to be on the diverse location of center-pole 4, first, second wedge it
Between distance be just obtained in that adjustment, the amount of floating in middle floating wedge block 5 is just obtained in that adjustment, is easy to according to guide rail
The groove width of groove is adjusting the wedge lock mechanism.Meanwhile, adjusting position of the limit screw cap 71 in adjusting screw can make dish
The pretightning force of spring 8 is adjusted, and so its coupling mechanism force just can be by the dish-shaped bullet of adjustment in locking for the wedge lock mechanism
The pretightning force of spring 8 is simple to operate adjusting, easy to use.
