Description
Technical field
The utility model relates to a kind of switch lock, particularly relates to a kind of lock construction that is applied to switchbox.
Background technology
Switchbox be by the electrical wiring requirement be assembled in switchgear, measuring instrument, protection electrical equipment and auxiliary equipment in sealing or the semiclosed metal cabinet or the screen width of cloth on, constitute low-voltage distribution equipment.Can connect or the branch deenergizing by manual or automatic switch during normal the operation.Switchbox and power distribution cabinet, switchboard, distribution panel etc. are the complete sets of equipment of installing equipment such as switch, instrument concentratedly.
Existing switchbox has and adopts the latch mode to carry out the chamber door locking, as shown in Figure 1, this lock construction comprises the pin rod (7) that is movably arranged on the chamber door (4), be arranged on the pin nose (9) on the casing (8), pin rod (7) is inserted on the pin nose (9), can be with fixing between chamber door (4) and the casing (8), pin handle (10) is set on the pin rod (7), pin handle (10) is enclosed within on the lock ear of below, lock, so just make chamber door (4) lock, but the lock construction of this mode generally all is exposed at the outer end, is easy to be subjected to rain erosion, makes pin rod (7), pin nose (9) etc. gets rusty easily, just very inconvenient during use, changing has increased cost again.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, and a kind of lock construction that is applied to switchbox is provided, the defective of avoiding existing switchbox lock construction to get rusty easily.
The purpose of this utility model is achieved through the following technical solutions: the lock construction that is applied to switchbox, comprise lock body, described lock body comprises rotating shaft, handle and block tongue, described rotating shaft rotation is installed on the chamber door of switchbox, rotating shaft runs through chamber door, and rotating shaft is positioned at the end fixed installation block tongue of chamber door inboard, and block tongue is strip, its bearing of trend is vertical with rotating shaft, and rotating shaft is positioned at an end in the chamber door outside handle is installed.
Described handle and rotating shaft are connected through the hinge.
The plane of rotation of described handle is vertical with the bearing of trend of block tongue.
On the described chamber door below the handle pin joint or above be provided with one the lock ear, handle is provided with and locks the lock earhole that the ear size cooperates, the lock ear is consistent to the distance values of handle pin joint with the lock earhole to the distance of handle pin joint, makes that the lock earhole on the handle can overlap the ear of locking.
Described lock ear is provided with lockhole, and lockhole is greater than the thickness of handle to the distance of chamber door, and when promptly handle was inserted in the lock ear, lockhole was exposed at the outer end of handle.
Described handle is that plastics are made.
The beneficial effects of the utility model are: the metal block tongue of realizing locking between chamber door and the casing is arranged in the chamber door, has avoided rainwash, this device has advantages such as easy to use.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the schematic diagram of lock body;
Fig. 4 is the rear elevation of Fig. 3;
Fig. 5 is a scheme of installation of the present utility model;
Among the figure, the 1-rotating shaft, the 2-handle, the 3-block tongue, the 4-chamber door, 5-locks ear, and 6-locks earhole, the 7-pin rod, the 8-casing, 9-sells nose, 10-pin handle, 11-lockhole.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but structure of the present utility model is not limited only to following examples:
[embodiment]
As Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, be applied to the lock construction of switchbox, comprise lock body, described lock body comprises rotating shaft 1, handle 2 and block tongue 3, and described rotating shaft 1 rotation is installed on the chamber door 4 of switchbox, and rotating shaft 1 runs through chamber door 4, rotating shaft 1 is positioned at the end fixed installation block tongue 3 of chamber door 4 inboards, block tongue 3 is strip, and its bearing of trend is vertical with rotating shaft 1, and rotating shaft 1 is positioned at an end in chamber door 4 outsides handle 2 is installed.
Described handle 2 is connected through the hinge with rotating shaft 1, and handle 2 promptly can bend, and has reduced touching.
The plane of rotation of described handle 2 is vertical with the bearing of trend of block tongue 3, and handle 2 is vertically downward or upwards the time, and block tongue 3 can block casing 8, makes chamber door 4 not open.
On the described chamber door 4 below handle 2 pin joints or above be provided with one the lock ear 5, handle 2 is provided with and locks the lock earhole 6 that ear 5 sizes cooperate, lock ear 5 is consistent to the distance values of handle 2 pin joints with lock earhole 6 to the distance of handle 2 pin joints, makes that the lock earhole 6 on the handle 2 can overlap the ear 5 of locking.
Described lock ear 5 is provided with lockhole 11, lockhole 11 is greater than the thickness of handle 2 to the distance of chamber door 4, and when promptly handle 2 was inserted in lock ear 5, lockhole 11 was exposed at the outer end of handle 2, at this moment adding at lockhole 11 places locks promptly can lock handle 2, thereby limits the rotation of handle 2.
Described handle 2 is made for plastics, and handle 2 can not get rusty like this, guarantees the comfortableness of using.
When the utility model is installed, lock construction should be installed in the edge of chamber door 4, as Fig. 2, make the length of block tongue 3 can exceed the edge of chamber door 4, hand turning handle 2 just can drive rotating shaft 1, thereby driving block tongue 3 rotates, block tongue 3 is directed downwards or upwards the time, block tongue 3 all is positioned at the scope of chamber door 4, to not constituting barrier effect between chamber door 4 and the casing 8, but when block tongue 3 during towards chamber door 4 edges, the part that exceeds of block tongue 3 is promptly blocked casing 8, make chamber door 4 outwards not open, then handle 2 is pressed onto on the lock ear 5, make that the lock earhole 6 on the handle 2 can overlap the ear 5 of locking, after locking on the lockhole 11, handle 2 just is fixed, thereby has limited the rotation of block tongue 3, has so just locked chamber door 4.
