Description
Technical field
The present invention relates to a kind of lock, be specifically related to a kind of door lock for rack.
Background technology
rack is generally the cabinet for depositing related control device made with cold-rolled steel sheet or alloy, the equipment being put in its inside is had to the effect of protection and shield electromagnetic interference.Rack is divided into server cabinet, network cabinet and electric equipment rack usually, for the ease of dismounting maintenance, rack is all provided with cabinet door, cabinet door arranges door lock.Adopt coded lock for the electric equipment gate lock for cabinet part in various automatic assembly line at present, often there is following problem in this lock: 1. usually needs electronic devices and components, complex structure; 2. the internal structure of lock is placed in the space of an independent closed usually, once break down in lock inside, repairs very inconvenient.
Summary of the invention
The invention provides the gate lock for cabinet that a kind of structure is simple, be convenient to maintenance.
The present invention program is as follows: a kind of gate lock for cabinet, comprise baffle plate, described baffle plate is arranged on rack, dead bolt is equipped with described baffle plate lapping switch, especially, this programme is provided with vertical supporting bracket in cabinet door, the first back shaft and the second back shaft is vertically disposed with in the side of described supporting bracket, be hinged on the first back shaft in the middle part of described dead bolt, second back shaft is hinged with the first clamp, described first clamp top can with described dead bolt bottom clamping, described supporting bracket is provided with second clamp that can block the first clamp bottom, described first back shaft is arranged with the first torsion spring, second back shaft is arranged with the second torsion spring, the bottom of described dead bolt is located in one end of first torsion spring, the other end of the first torsion spring is walked around the first back shaft and is connected with one end of the second torsion spring, the other end of the second torsion spring is located at the top of described first clamp.
Beneficial effect of the present invention is as follows: 1. adopt pressing flip-over type unlocking structure, namely by pressing first clamp, the first clamp top and dead bolt are departed from, and under the effect of dead bolt power above the first torsion spring is outwards oblique, dead bolt top and baffle plate depart to realize unlocking, and structure is simple, easy to operate; 2. dead bolt and the lock construction that unwinds are set directly at inside cabinet door, without the need to closing; And dead bolt, supporting bracket, the first back shaft, the second back shaft, the first clamp and the second clamp are all not fragile in use, and the first torsion spring and the second torsion spring are if any distortion or damage, can directly change, easy to maintenance.
Further, the drive division that described dead bolt comprises the clinch on top, stepped articulated section, middle part is connected with the first torsion spring with bottom, the bottom of described drive division is bent inwardly to inverted "L" shaped structure.Above-mentioned stepped lock bolt structure design can reduce the design length of dead bolt, and the design that the bottom of drive division is bent inwardly to inverted "L" shaped structure can make the clamping on dead bolt bottom and the first clamp top more stable.
Further, have groove in the inner side of described clinch, the upper cell wall ecto-entad of described groove is downward-sloping, is provided with the fixture block mated with described groove shapes in the end of described baffle plate.Realizing the overlap joint of dead bolt and baffle plate by being snapped in by fixture block in groove that dead bolt top arranges, guaranteeing to lock more firm.
Further, in order to operation of being more convenient for, cabinet door has conical through-hole, and the side that described first clamp is positioned at cabinet door is provided with button projection, and described button projection is through described conical through-hole.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of gate lock for cabinet locking state of the present invention;
Fig. 2 is the structural representation of gate lock for cabinet released state in Fig. 1 embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
A kind of gate lock for cabinet as shown in Figure 1 and Figure 2, comprises baffle plate 1, supporting bracket 2, first back shaft 3, second back shaft 4, dead bolt 5, first clamp 6, second clamp 7, first torsion spring 8 and the second torsion spring 9.
Baffle plate 1 is arranged on rack 10, and the below of rack 10 is cabinet door 11, and cabinet door 11 arranges vertical supporting bracket 2, first back shaft 3 and the second back shaft 4 setting up and down in the side of supporting bracket 2.
Dead bolt 5 can be monoblock construction, also can be stepped construction, and the present embodiment is preferably stepped construction, and its concrete structure is: the drive division 53 that dead bolt 5 comprises the clinch 51 on top, stepped articulated section 52, middle part is connected with the first torsion spring 8 with bottom.The inner side of clinch 51 has groove 511, and the upper cell wall ecto-entad of groove 511 is downward-sloping, is provided with the fixture block 11 with described groove 511 form fit in the end of baffle plate 1, and during locking, dead bolt 5 and baffle plate 1 are inserted into groove 511 inside lap by fixture block 11 and lock; Articulated section 52 is hinged on the first back shaft; The bottom of drive division 53 is bent inwardly to inverted "L" shaped structure, and dead bolt 5 bottom realizes locking by the inverted "L" shaped structure of drive division 53 bottom and the first clamp 6 top clamping.
First clamp 6 one end is hinged on the second back shaft 4, the other end of the first clamp 6 is by the second clamp 7 clamping, second clamp 7 is arranged in supporting bracket 2, the interface arrangment of the first clamp 6 and the second clamp 7 is: the Access Division be arranged on the first clamp 6 is bent inwardly to inverted "L" shaped structure, so that clamping is more stable.
Winding first torsion spring 8 on the first back shaft 3, winding second torsion spring 9 on second back shaft 4, one end of first torsion spring 8 is connected to the bottom of described dead bolt 5, the other end of the first torsion spring 8 is walked around the first back shaft 3 and is connected with one end of the second torsion spring 9, and the other end of the second torsion spring 9 is connected to the top of the first clamp 6.
For the ease of switching manipulation, cabinet door 11 has conical through-hole 111, the side that the first clamp 6 is positioned at cabinet door 11 is provided with button projection 61, and button projection 61 is through described conical through-hole.
The present embodiment scheme works principle is as follows: under locking state, second clamp blocks the bottom of the first clamp, second torsion spring makes the first clamp top block the bottom of dead bolt to the active force of the outside oblique top of the first clamp one, with the first back shaft for fulcrum, dead bolt top will overlap with baffle plate, be in locking state, now the first torsion spring fringe dead bolt bottom has the active force of an outside oblique top.
During unblock, in door, press the first clamp, the first clamp with the second back shaft for fulcrum rotates inside door, first clamp top and dead bolt bottom depart from, and dead bolt is under the effect of the power of the first torsion spring, and dead bolt is put by bottom, the dead bolt top bottom, dead bolt top and baffle plate depart from, and because baffle plate is arranged on rack, dead bolt is arranged on the supporting plate by the first back shaft, supporting bracket is arranged in cabinet door, therefore, after dead bolt and baffle plate depart from, freely cabinet door can be opened.When closing cabinet door, only need press the drive division of dead bolt bottom, make drive division and the first clamp clamping.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that to those skilled in the art, and under the prerequisite not departing from structure of the present invention, can also make some distortion and improvement, these also should be considered as within protection scope of the present invention.
