Description

Lock for cupboard door of electric apparatus

The invention belongs to lock class technical field.

Existing regulator cubicle door lock is divided into handle type and planar two classes.Handle type door lock branch, close reliable, but outward appearance is relatively poor, handle give prominence to the cabinet door, colludes easily and hangs the electrical operation personnel clothing, the generation unsafe factor.The planar door lock, though good looking appearance, the time the relevant phenomenon that do not go up, do not open.Task of the present invention is the defective at above-mentioned two class door locks, designs a kind of door lock new construction, reaches to open and close flexible, safe and reliable purpose.

The present utility model is the door lock that a kind of regulator cubicle is used, form by lock body, lock hook, pivoted housing and handle etc., the handle that it is characterized in that this door lock is equipped with spring, and has ratchet and ratchet spring and mechanisms such as button and button spring; This door lock is when locking state, and handle is hidden in the lock body, and ratchet makes the handle location; Lift button ratchet is return, handle thereby take off mouth, because handle spring tension force makes handle eject lock body, angle of rotary handle, lock hook is threaded off, and door is opened.

Below in conjunction with accompanying drawing the present invention is described in detail.

The structure of electric cabinet lock as shown in Figure 1, it partly is made up of lock body (1), latch hook (2), pivoted housing (3), handle (4) and handle spring (5), ratchet (6) and ratchet spring (9), button (7) and button spring (8) etc.; Each structure and binding each other thereof partly is: a. lock body (1) structure: lock panel back side close end respectively has a garden post with internal thread, is used for door lock is installed on the cabinet door by cup-shaped pressing plate and screw; The garden through hole that lock body (1) panel top has an ellipse garden shape handle to sink to groove and match with handle (4) garden tube, pivoted housing (3), the bottom, hole has step to make pivoted housing (3) spacing, on the garden ring of face garden, the lock body back side through hole latch hook (2) rotary stopper post is arranged; Hole, one button garden is arranged at lock body (1) panel bottom, and the button gathering sill is arranged in the hole, and corresponding button hole, the lock body back side is a rectangular slot, and it communicates with the garden through hole, is the ratchet passage; Ratchet (6) guide table and cover plate platform are arranged in the groove along its length. B. handle (4) structure: handle (4) garden tube partly has an oblique breach, handle (4) when pushing ratchet (6) tongue end snap in breach; Stalk both sides, handle (4) garden are garden arc groove shape, are complementary with pivoted housing (3), latch hook (2) endoporus, and garden stalk end has internal thread; The symmetrical recess of pivoted housing (3) rear end face has screw, and being meshed with latch hook (2) links with screw; Handle (4) is loaded onto successively spring (5), pivoted housing (3), is packed into from the positive garden of lock body (1) through hole, blocked by ratchet (6), load onto latch hook (2), handle garden stalk end is loaded onto packing ring, screw, prevents from coming off when handle from ejecting. C. button (7) structure: the guide lugs that two symmetries are arranged on the button (7); Tiltedly take on the protrusion that the interior inclined-plane correspondence position of ratchet (6) square frame has; Button (7), ratchet (6) are successively long from the lock body back of the body The square groove lock body of packing into, each loading spring is integrated itself and lock body riveting with cover plate. Shown in Figure 1 is that door lock is being locked state status, and handle is hidden in the lock body (1), and ratchet (6) makes the handle location; When need are opened; Lift button (7) and force ratchet (6) to be return, handle (4) is threaded off and is ejected lock body, and (4) 90 ° of rotary handles take off lock hook (2) and collude, and door is opened; When needs are locked a door, after door closed up doorframe, (4) 90 ° of rotary handles made latch hook (2) collude upper door frame, pushing handle (4) enters in the lock body (1), because the tension force of spring (9) advances ratchet (6) to make handle (4) location.

Electric cabinet lock of the present invention can arrange respectively hole (11), (12) of sinking on handle (4) and button (7), for adding lead sealing usefulness, such as Fig. 3. Because the operation of regulator cubicle only limits to electrical operation personnel or electric industry full-time staff, when being used for the electrical metering cabinet door lock, for electricity theft prevention and produce other situation, the leading sealing mechanism is necessary.

The button of regulator cubicle door lock of the present invention (7) can be lock core (15), it is characterized in that it controls ratchet (6) with lock core, and lock core is by reed (14), blade compositions such as (16), as shown in Figure 4.Lock core can be some the shared keys of lock, also can be the special-purpose key of a lock core.Be suitable for having the cabinet of specific (special) requirements.

The latch hook of regulator cubicle door lock of the present invention (2) can be equipped with set screw (10), sees Fig. 1.In order to regulate the distance between latch hook (2) and cabinet doorframe, make when locking closely docile.

Embodiment: electrical metering cabinet door lock.Lock body (1), lock hook (2), pivoted housing (3), handle (4), ratchet (6), button parts such as (7) all adopt the zinc alloy diecasting manufacturing.On the handle clockwise direction half-twist cabinet door lock, counterclockwise half-twist cabinet door is opened.Handle (4) and button (7) external surface are provided with lead sealing respectively with sinking to hole (11), (12), can add lead sealing in the time of on the cabinet door lock, as shown in Figure 1 and Figure 2.

The present utility model electric cabinet lock also can be widely used in the door lock in mechanical cabinet, archives stationery and other cabinet, be specially adapted to the door lock of electrical metering cabinet, high and low pressure pass cabinet, open and close flexibly, safe and reliable, have obvious economic benefit and social benefit.
