Description
Technical Field
The invention belongs to the field of communication cabinet production and manufacturing, and particularly relates to an openable locking sealing structure of a communication cabinet door.
Background
The communication cabinet refers to a cabinet for communication, and the products are cabinet shells which are processed by sheet metal equipment. The existing door lock of the communication cabinet has the following problems that the cabinet door of the communication cabinet is usually opened when being maintained or checked by professional staff and is normally closed, so that the cost for providing the special door lock on the cabinet door is high; the door plate and the door frame are usually left with allowance due to processing errors and deformation after metal processing prevention, so that a certain gap exists between the door plate and the door frame, the cabinet and the door plate cannot be sealed, dust easily enters the cabinet from the gap, and poor heat dissipation and other faults of the cabinet are easily caused; when the existing cabinet door lock is used for locking the cabinet door, the existing cabinet door lock locks the cabinet door through a mode of hooking a fixing piece in the cabinet, the cabinet door lock is only blocked, deformation of an elastic piece is avoided, so acting force for mutually pressing the cabinet door and a door frame is not generated, gaps exist between the door plate and the door frame, dust does not enter in sealing mode on one hand, when wind and rain are sprayed on the other hand, the cabinet door shakes to impact the door frame to generate larger noise and damage due to long-time collision, and rainwater can enter the cabinet through the gaps to cause danger.
Disclosure of Invention
The invention aims to solve the technical problem of providing an openable locking sealing structure of a communication cabinet door, and aims to provide a structure capable of tightly pressing the cabinet door at an opening of a cabinet body to be locked and sealed.
The technical scheme for solving the technical problems is as follows: the utility model provides a but locking seal structure is opened and close to communication cabinet door, its includes the cabinet door body, one side of cabinet door body is articulated with a side board of the cabinet body, the opposite side of cabinet door body is equipped with the pinhole, swing joint has the latch lever in the pinhole, the latch lever stretches into the internal one end of cabinet is equipped with the couple, the other end of latch lever is equipped with the handle, be equipped with on the other curb plate inner wall of the cabinet body and supply the boss that the couple was hung and hold, the latch lever is located be equipped with on the pole section in the cabinet body and prevent it from pull out in the pinhole, the latch lever is located the cover is equipped with first hold-down spring on the pole section outside the cabinet body, the one end of first hold-down spring with the outer wall butt of cabinet door body, the other end of first hold-down spring with the handle butt presses and rotates the latch lever extremely during the couple is hung and is held in the boss, first hold-down spring is in compression state with the cabinet door body is pressed towards the cabinet body.
On the basis of the technical scheme, the invention can be improved as follows.
Further, the polytetrafluoroethylene sleeve is embedded and fixed in the pin hole, and the locking rod penetrates through the polytetrafluoroethylene sleeve and is in clearance fit with the polytetrafluoroethylene sleeve.
The beneficial effect of adopting above-mentioned further scheme is that polytetrafluoroethylene coefficient of friction is little, and frictional force is little, can guarantee that the locking lever can more smoothly stretch into withdraw from and rotate, reduces the wearing and tearing of locking lever simultaneously.
Further, the locking rod is located on the rod section in the cabinet body, a second compression spring is sleeved on the rod section, one end of the second compression spring is abutted to the limiting protruding block, and the other end of the second compression spring is abutted to the inner wall of the cabinet door body.
The beneficial effect of adopting above-mentioned further scheme is, set up the second hold-down spring then the dead lever under the dual effect of compressing tightly of first and second hold-down spring, when not receiving the exogenic action, can be steady and the position relatively fixed stay in the pinhole.
Further, the first compression spring and the second compression spring are respectively in butt joint with the outer wall and the inner wall of the cabinet door body correspondingly through polytetrafluoroethylene ring pieces sleeved on the locking rod.
The beneficial effect of adopting above-mentioned further scheme is, the setting of two polytetrafluoroethylene ring piece can make the pinhole both sides more a sealed effect respectively on the one hand, prevents that the dust from getting into the cabinet through the clearance of pinhole and locking lever internal, and on the other hand is more important its coefficient of friction little, and corresponding hold-down spring tip is through its contact with cabinet door body, and then the locking lever is rotated, and the torsional force that the spring received is little, and is not fragile.
Further, the locking rod is close to the rod section of the handle and is connected with an adjusting nut in a threaded mode, and one end, far away from the cabinet door body, of the first compression spring is abutted to the adjusting nut.
The beneficial effect of adopting above-mentioned further scheme is, set up adjusting nut then can be when the couple hooks the projection, nimble regulation first hold-down spring is to the pressure of cabinet door body, guarantees to possess better sealed effect.
Further, the position of the convex column is higher than the position of the pin hole, the hook is a right-angle hook, a hook groove for hanging the hook is formed in the convex column, and a balancing weight is fixed at one end, far away from the locking rod, of the hook.
The adoption of the further scheme has the beneficial effects that when the hook is not hooked on the convex column and is not affected by external force, the balancing weight naturally enables one end of the hook, which is far away from the locking rod, to be located below due to the action of gravity, so that the hook is not affected by the convex column located above when the door is closed.
Further, a plurality of pin holes are uniformly formed in the cabinet door body at intervals from top to bottom, each pin hole is correspondingly provided with a locking rod, and a plurality of convex columns are correspondingly arranged on corresponding side plates of the cabinet body.
The beneficial effect of adopting above-mentioned further scheme is, the cooperation of a plurality of pinholes, locking lever, projection can guarantee good locking fixed and sealed effect.
Compared with the prior art, the invention has the beneficial effects that:
the cabinet door body is tightly hooked and fixed with the convex column on the inner wall of the corresponding side plate of the cabinet through the locking rod which is provided with the hook at one end and the handle at the other end and is sleeved with the first compression spring, and the compressed elastic force of the first compression spring enables the cabinet door body to be pressed towards the cabinet body when being tightly hooked and fixed, so that the cabinet door has good sealing effect, is dustproof and rainproof; simple structure, convenient operation does not need to be equipped with the key.
