Embodiment one

As shown in Fig. 1 ~ Fig. 5, the present embodiment provides a kind of closed grip handle locks of close type, including：Fixed part 2, fixed part 2 wrap Include column 203；Tight lock part 1, tight lock part 1 include handle 103, plectrum 104, hook plate 105 and torsional spring 106；Plectrum 104 is close to column 203 one end is fixedly connected with handle 103；The one end of plectrum 104 far from column 203 and the one end of hook plate 105 far from column 203 Connection is rotated coaxially by the realization of torsional spring 106；Plate 105 is hooked close to one end of column 203 equipped with the hook slot for catching on column 203 1052.The effect of torsional spring 106 is to keep plectrum 104 opposite with the steering of plate 105 is hooked.

In this present embodiment, the closed grip handle lock of close type further includes：Not rounded straight slot 1042, not rounded straight slot 1042, which is located at, to be dialled In piece 104, handle 103 is equipped with and is matched with not rounded straight slot 1042 and be inserted into the connection boss 1031 in not rounded straight slot 1042；Limit Position bolt 108, with connect boss 1031 be threadedly coupled, caging bolt 108 by gasket 109 will connection boss 1031 be fixed on it is non- In circle straight slot 1042.Specifically, the sectional view of connection boss 1031 is hexagon, square, rectangle or triangle etc. Regular figure or other irregular figures.Preferably, it hooks and is equipped with arc groove 1053 in plate 105, caging bolt 108 runs through arc The center of circle of shape slot 1053, arc groove 1053 is located on the straight line at 108 place of caging bolt.

In this present embodiment, the closed grip handle lock of close type further includes：First hole 1041 is located at plectrum 104 far from column 203 One end, the axis in the first hole 1041 and the axis of torsional spring 106 are point-blank；Second hole 1051, the axis in the second hole 1051 Line and the axis in the first hole 1041 are point-blank；Rivet 107 runs through torsional spring 106, the first hole 1041 and the second hole 1051. Wherein, a toggle 1061 of torsional spring 106 is connect with plectrum 104, another toggle 1061 and the hook plate 105 of torsional spring 106 Connection.Specifically, torsional spring 106 may be implemented to rotate coaxially and ensure the phase between them between plectrum 104 and hook plate 105 To position.

In this present embodiment, tight lock part 1 further includes：First shell 101；First bottom plate 102, plectrum 104 hook 105 and of plate In the space that torsional spring 106 is respectively positioned on first shell 101 and the first bottom plate 102 is formed.Fixed part 2 further includes：Second shell 201, Second shell 201 is equipped with notch 2011 close to the side of tight lock part 1；Second bottom plate 202, column 203 are fixed on the second bottom plate 202 On.Wherein, the first bottom plate 102 is equipped with the recessing groove 1021 for stepping down for column 203 close to one end of column 203.Hook slot 1052 can be entered by notch 2011 in the space between the second bottom plate 202 and second shell 201, and then catch on column 203.

In this present embodiment, lock core 110 can be set on handle 103, only use ability turning handle after key unlocking Hand 103.

Specifically, as shown in figure 4, can first be mounted on fixed part 2 on the nowel 4 of babinet, tight lock part 1 is mounted on case In the upper cover 3 of body, handle 103 is first rotated clockwise, so that handle 103 is in position shown in Fig. 4, then in upper cover 3 and nowel 4 Between the setting sealing elements such as rubber pad or sealing ring 5 and close babinet.When handle 103 is gone to Fig. 4 from position shown in Fig. 2 Shown in position when, with reference to Fig. 2 it is found that plectrum 104 can with connect boss 1031 be axis both clockwise rotation, simultaneously because torsional spring 106 elastic force effect, hooking plate 105 can be rotated counterclockwise with rivet 107 for axis, in the collective effect of handle 103 and torsional spring 106 Under, hooking slot 1052 can turn right moved beneath, then, hook plate 105 and misplace with the first bottom plate 102, the notch opening of recessing groove 1021, The upper cover 3 of babinet is closed at this time, and column 203 will enter in recessing groove 1021.Then another mistake hour hands swing handle 103, makes Handle 103 goes to position shown in fig. 5 from position shown in Fig. 4, hooks the direction of motion of slot 1052 and becomes upper direction of turning left, together When so that column 203 is caught on by hook slot 1052.When hook plate 105 turns left upper direction, it is equivalent to and gives upper cover 3 one to the right Power, case lid compresses sealing element 5 under the action of this power, improves air-tightness.

In this present embodiment, as shown in Fig. 6 ~ Fig. 8, first shell 101 is equipped with limit convex close to the side of the first bottom plate 102 The middle part of platform 111, positive stop lug boss 111 is equipped with the through hole that axis is overlapped with the axis of positive stop lug boss 111, and connection boss 1031 passes through It wears through hole and then is connect with plectrum 104.The cross recess that positive stop lug boss 111 is made of the first slot 1115 and the second slot 1116 point It is cut into four pieces, respectively the first limited block 1111, the second limited block 1112, third limited block 1113 and the 4th limited block 1114, Wherein the first limited block 1111 is equipped with escape groove.Plectrum 104 is equipped with restriction protrusion 1043 close to the side of positive stop lug boss 111, When plectrum 104 is in first position shown in fig. 6, restriction protrusion 1043 is located in the first slot 1115, due to the second limited block 1112 have blocked restriction protrusion 1043, it is possible to limit plectrum 104 and continue to rotate to third limited block 1113；Swing handle 103 make plectrum 104 go to the second position shown in Fig. 7, and restriction protrusion 1043 is gone to by escape groove in the second slot 1116, due to 4th limited block 1114 has blocked restriction protrusion 1043, it is possible to limit plectrum 104 and continue to rotate to third limited block 1113； It is achieved in 90 ° of rotary stoppers of handle 103.Further, when the use of key being that lock core 110 is locked, lock core 110 can stretch out Lock tongue 1101, lock tongue 1101 is put in the first slot 1115 or the second slot 1116, and then handle 103 is prevented to be rotated further.When making It is after lock core 110 is unlocked with key, lock tongue 1101 can retract, and then handle 103 can be rotated further.

" first " herein, " second " have no special meaning just for the sake of being distinguish in description.

It is to be understood that above-mentioned specific implementation mode is only the preferred embodiment and institute's application technology of the utility model Principle, in technical scope disclosed in the utility model, what any one skilled in the art was readily apparent that Change or replacement should all be covered within the protection scope of the present utility model.
