Description
Technical field
The invention belongs to communication cabinets to manufacture field, and in particular to a kind of lock sealing knot able to turn on or off of communication cabinet cabinet door
Structure.
Background technique
Communication cabinet refers to that the case and cabinet for being used in communication aspect, this kind of products are mainly processed by Plate working equipment
At cabinet casing.It is had the following problems in existing communication cabinet door lock, the cabinet door of usual communication cabinet is by professional work
It can just be opened when personnel's maintenance or inspection, it is in normally off under normal circumstances, therefore dedicated door is equipped in cabinet door
Lock higher cost；Mismachining tolerance is typically due between door-plate and doorframe and prevent deformation after intermetallic composite coating and it is remaining have a margin, because
Make to seal between cabinet and door-plate there are certain interval between this door-plate and doorframe, dust is easy to enter machine from the gap
Inside cabinet, it be easy to cause cooling machine cabinet bad and other failures；Using existing gate lock for cabinet come when locking cabinet door, due to
Existing gate lock for cabinet is that cabinet door is locked by way of the fixing piece in hook lock cabinet, is only barrier effect, the shape of nonelastic part
Be changed into use, therefore and there is no the active forces for compressing cabinet door and doorframe each other so that there are gap between door-plate and doorframe,
On the one hand it is poorly sealed have dust entrance, when on the other hand there is wind and weather situation, cabinet door shake knocking door case generate compared with
Big noise and long-time collision effect is easy to damage, rainwater can enter in cabinet through gap, cause dangerous.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of lock sealing structures able to turn on or off of communication cabinet cabinet door, it is intended to
Cabinet door can be pressed in cabinet body opening with the structure of lock sealing by providing one kind.
The technical scheme to solve the above technical problems is that a kind of lock sealing knot able to turn on or off of communication cabinet cabinet door
Structure comprising cabinet door ontology, the side of the cabinet door ontology and the side plate of cabinet body are hinged, and the other side of the cabinet door ontology is set
There is pin hole, check lock lever is connected in the pin hole, the check lock lever protrudes into the intracorporal one end of the cabinet and is equipped with hook, described
The other end of check lock lever is equipped with handle, and another side plate inner wall of the cabinet body is equipped with the pillar for the hook hanging support, described
Check lock lever is located at the intracorporal rod segment of the cabinet and is equipped with the spacing block set for preventing it from pulling out out of described pin hole, the check lock lever position
In being arranged with the first holddown spring in the rod segment outside the cabinet body, one end of first holddown spring and the cabinet door ontology
Outer wall abuts, and the other end of first holddown spring abuts with the handle, presses and rotate the check lock lever to the extension
When hook holds the pillar, first holddown spring is in compressive state so that the cabinet door ontology is pressed to the cabinet body.
Based on the above technical solution, the present invention can also be improved as follows.
Further, it is embedded in the pin hole and is fixed with polytetrafluoroethylene sleeve, the check lock lever passes through the polytetrafluoroethyl-ne
Alkene sleeve and with its clearance fit.
Beneficial effect using above-mentioned further scheme is that polytetrafluoroethylene (PTFE) coefficient of friction is small, and frictional force is small, it is ensured that lock
Tight bar can more smoothly protrude into the abrasion exited and rotated, while reducing check lock lever.
Further, the check lock lever, which is located in the intracorporal rod segment of the cabinet, is arranged with the second holddown spring, second pressure
One end of tight spring is abutted with the spacing block set, and the other end of second holddown spring and the inner wall of the cabinet door ontology support
It connects.
Beneficial effect using above-mentioned further scheme is, the second holddown spring of setting then check lock lever in first and second pressure
It, can be steady and position is relatively-stationary stays in pin hole when not by external force under the dual pressuring action of tight spring.
Further, first holddown spring and the second holddown spring are respectively poly- on the check lock lever by being sheathed on
Tetrafluoroethene ring plate correspondence is abutted with the outer wall of the cabinet door ontology and inner wall.
Beneficial effect using above-mentioned further scheme is on the one hand the setting of two polytetrafluoroethylene (PTFE) ring plates can make pin
More one of the sealing function of hole two sides difference, prevent dust from entering in cabinet body through the gap of pin hole and check lock lever, on the other hand heavier
What is wanted is that its coefficient of friction is small, and corresponding holddown spring end passes through itself and cabinet door body contacts, then when check lock lever rotates, spring
The twisting resistance being subject to is small, is hardly damaged.
Further, the check lock lever is threaded with adjusting nut in the rod segment of the handle, and described first compresses
Spring is abutted far from one end of the cabinet door ontology with the adjusting nut.
Beneficial effect using above-mentioned further scheme is that setting adjusting nut then can be when hook hooks pillar, spirit
For first holddown spring living that adjusts to the pressure of cabinet door ontology, guarantee has preferable sealing effect.
Further, the position of the pillar is higher than the position of the pin hole and the hook is right angle hook, on the pillar
Equipped with the hook groove for the hook hanging support, described one end for linking up with the separate check lock lever is fixed with clump weight.
Beneficial effect using above-mentioned further scheme is, does not hook pillar in hook and when not by external force, counterweight
Block is due to gravity located below naturally the one end for linking up with separate check lock lever, and hook is not located above when guaranteeing to close cabinet door
Pillar influences.
Further, uniform intervals are equipped with multiple pin holes from top to bottom on the cabinet door ontology and each pin hole is corresponding
Equipped with the check lock lever, multiple pillars are correspondingly provided in the respective side panels of the cabinet body.
Beneficial effect using above-mentioned further scheme is the cooperation of multiple pin holes, check lock lever, pillar, it is ensured that good
Be locked and sealing effect.
Compared with prior art, the beneficial effects of the present invention are:
Cabinet door ontology has handle with hook, the other end by one end and is arranged with the locking of the first holddown spring thereon
Pillar on bar and cabinet body respective side panels inner wall hooks fixation, and the elastic force effect of compressed first holddown spring makes cabinet door ontology
Be hooked fasten when by the power compressed to cabinet body, to play preferable sealing effect, dustproof and rainproof；Structure is simple, behaviour
Facilitate, does not need to be equipped with key.
