Example 1

As shown in fig. 1, 2, 3 and 4, the present invention provides a technical solution: the utility model provides a detachable fuel cell emergency power source, including power shell 1 and cap 2, power shell 1's top is provided with cap 2, disassembly groove 17 has been seted up to cap 2's inside, cap 2's inside is rotated and is connected with dwang 5, dwang 5's top extends to cap 2's top fixedly connected with dismantles knob 4, dwang 5's bottom extends to disassembly groove 17's inside fixedly connected with rotor plate 6 No. one, rotor plate 6's top and the one side that is located dwang 5 rotate and be connected with connecting rod 7, the one end fixedly connected with slide bar 9 of connecting rod 7, the inside of disassembling groove 17 and the one side that is located keeping away from dwang 5 rotate and be connected with pivot 10, No. two rotor plates 11 of bottom fixedly connected with of pivot 10, spout 8 has been seted up to No. two rotor plates 11's inside, slide bar 9 and spout 8 sliding connection.

In this embodiment, dismantle knob 4 through rotating and make dwang 5 drive a rotor plate 6 clockwise rotation, then the one end motion of a rotor plate 6 pulling connecting rod 7, make connecting rod 7 through slide bar 9 pulling No. two rotor plates 11 round pivot 10 clockwise rotation to a rotor plate 6 and No. two rotor plates 11 promote fixed fixture block 15 to both sides, are favorable to the quick shrink of fixed fixture block 15 to the inside of installation piece 13, thereby dismantle cap 2 fast.

Example 2

As shown in fig. 1, fig. 2, fig. 3 and fig. 4, the mounting blocks 13 are fixedly connected to the top of the power supply housing 1 in a bilateral symmetry manner, the mounting grooves 12 matched with the mounting blocks 13 are symmetrically formed in the housing cover 2 and located in the dismounting groove 17 in a bilateral symmetry manner, one end of each mounting block 13 extends into the corresponding mounting groove 12, the reset spring 14 is arranged inside each mounting block 13, one end of the reset spring 14 is fixedly connected with the fixed fixture block 15, one end of the fixed fixture block 15 extends into the dismounting groove 17, and the fixed fixture block 15 is clamped with the dismounting groove 17.

Wherein, the top bilateral symmetry fixedly connected with handle 3 of cap 2 can make things convenient for the faster cap 2 of opening of staff through the handle 3 that sets up, then can look over power shell 1's inside to reduce the strain intensity that the staff pointed, alleviateed the work load that the staff's finger bore.

Wherein, the inside fixedly connected with radiator-grid 16 of power shell 1, can conveniently dispel the heat inside power shell 1 fast through the radiator-grid 16 that sets up to fuel cell's radiating efficiency has been improved, thereby further extension fuel cell's life.

The top of the fixing clamping block 15 is in an arc-shaped structure, and the fixing clamping block 15 in the arc-shaped structure facilitates pushing of the housing cover 2, so that the fixing clamping block 15 is retracted towards the inside of the mounting block 13.

Wherein, the degree of depth of mounting groove 12 is greater than the height of installation piece 13, is greater than the mounting groove 12 of installation piece 13 height through setting up, can avoid cap 2 with power supply housing 1 installation in-process, because the degree of depth that installation piece 13 highly is greater than mounting groove 12 leads to the problem that cap 2 and power supply housing 1 can't install.

Wherein, fixed fixture block 15 and the inside sliding connection of installation piece 13, through the inside slip of fixed fixture block 15 that sets up at installation piece 13, can reduce the wearing and tearing between fixed fixture block 15 and the installation piece 13 to fixed fixture block 15's life has been prolonged.

Wherein, the one end of the first rotor plate 6 and the second rotor plate 11 is circular arc structure, through the circular arc first rotor plate 6 and the circular arc second rotor plate 11 that set up, more conveniently promote fixed fixture block 15, reduce the wearing and tearing between first rotor plate 6 and second rotor plate 11 and fixed fixture block 15 simultaneously, increase of service life reduces the fund consumption.

Wherein, the length of a rotor plate 6 equals the length of No. two rotor plates 11, and a rotor plate 6 through setting up equals with No. two rotor plates 11 length, can make things convenient for the staff to be in 2 dismantlements in-process rotor plates 6 and No. two rotor plates 11 promotion fixed fixture block 15 simultaneously to the shell cover.

Wherein, dismantle knob 4 and adopt rubber material to make, through the dismantlement knob 4 that adopts rubber material, can avoid the staff when rotating dismantlement knob 4, skid with dismantling knob 4 because of having the finger that the sweat leads to on the finger to influence the staff and normally dismantle casing lid 2.

In this embodiment, through covering cap 2 downwards, make installation piece 13 insert the inside of mounting groove 12, then the inner wall of mounting groove 12 promotes the arc surface of fixed fixture block 15, make fixed fixture block 15 to the inside extrusion reset spring 14 of installation piece 13, after installation piece 13 inserts mounting groove 12 completely, fixed fixture block 15 blocks into the inside of dismantling groove 17 under reset spring 14's spring action, be favorable to the staff to the quick installation of cap 2, the installation effectiveness of cap 2 has been improved.

The working principle is as follows:

as shown in fig. 1, fig. 2, fig. 3 and fig. 4, when the fuel cell inside the emergency power supply needs to be replaced and maintained, the disassembly knob 4 is rotated to drive the first rotating plate 6 to rotate clockwise, then the first rotating plate 6 pulls one end of the connecting rod 7 to move, so that the connecting rod 7 pulls the second rotating plate 11 to rotate clockwise around the rotating shaft 10 through the sliding rod 9, so that the first rotating plate 6 and the second rotating plate 11 push the fixed fixture blocks 15 to both sides, so that the fixed fixture blocks 15 are rapidly contracted into the installation blocks 13, then the fixed fixture blocks 15 are separated from the inside of the disassembly grooves 17, thereby rapidly disassembling the housing cover 2, after the replacement of the fuel cell inside the emergency power supply is completed, the housing cover 2 is covered downwards to insert the installation blocks 13 into the inside of the installation grooves 12, then the inner walls of the installation grooves 12 push the arc surfaces of the fixed fixture blocks 15, so that the fixed fixture blocks 15 extrude the return springs 14 to the inside of the installation blocks 13, after the installation block 13 is completely inserted into the installation groove 12, the fixed fixture block 15 is clamped into the interior of the dismounting groove 17 under the elastic action of the return spring 14, which is beneficial for the quick installation of the shell cover 2 by the working personnel and improves the installation efficiency of the shell cover 2.

Finally, it should be noted that: the above-mentioned embodiments are only used for illustrating the technical solution of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
