Description

A kind of quick locking of drum magazine, opening device

Technical field

The technical field of drum magazine is the utility model is related to, more particularly in a kind of quick locking of drum magazine, unlatching Device.

Background technology

Sealing locking, the opening device various structures of cover, the at present domestic various lockings for being used for cartridge cover, unlatching fill In putting, exist component it is more, it is complicated, operation it is inconvenient, in transit easily disengage and flimsy problem, structure can not Lean on；Urgent need will research and develop a kind of locking, open reliable convenient and well-set cartridge cover locking system.

Utility model content

In view of this, the utility model provides a kind of quick locking of drum magazine, opening device, and sound construction is reliable, Locking, unlatching are convenient, can effectively prevent maloperation, reduce the operating time.

A kind of quick locking of drum magazine, opening device, the locking system include tensing hook, cover, dead bolt, attacker, Flexible member and handle；Ancillary equipment is cylinder；

Described to tense the boss socket hooked with the top of cover and spacing by anti-loosing screw, the handle turns with tensing to hook Dynamic connection, handle junction is cam structure, and winding by hand junction, which is rotated, makes cam structure compress and open cover；Attacker one end It is rotatablely connected with handle end, rotation direction is consistent with the rotation direction of handle, and attacker's other end is matched somebody with somebody by dead bolt with tensing hook Close, described to tense the lockhole for hooking and being provided with and being engaged with dead bolt, flexible member is arranged between handle and attacker；

During locking, rotation is tensed to hook and is engaged until tensing to hook with the limiting stand on cylinder, rotates down handle, cover to Lower hold-down barrel, while dead bolt is spacing in the lockhole for tensing hook by the active force of flexible member, makes cover hold-down barrel；Open Qi Shi, external force effect make dead bolt completely disengaged with tensing hook, and rotation tenses to hook staggers with the limiting stand on cylinder, releases handle pair The compression of cover, cover are opened.

Further, the flexible member is torsion spring, and torsion spring is rotatably assorted by torsion spring bearing pin with handle, one branch of torsion spring Leg coordinates with handle, and another supporting leg of torsion spring coordinates with attacker, the spacing lockhole hooked in tension of active force that dead bolt passes through torsion spring It is interior.

Further, it is provided with sealing ring with cylinder contact position inside the cover.

Beneficial effect：

1. compared with prior art, the utility model structure operation action is single, drum magazine is completed by rotating handles Quick locking, unlatching, can effectively prevent maloperation, reduce the operating time；And the cooperation with dead bolt makes structure more firm Reliably, also will not arbitrarily disengage in transit.

2. the utility model realizes dead bolt with tensing the cooperation hooked using torsion spring, part is simply ingenious.

3. being provided with sealing ring with cylinder contact position inside the utility model cover, sealing ring passes through deformation after handle compression Reach sealing effectiveness.

Embodiment

With reference to the accompanying drawings and examples, the utility model is described in detail.

The utility model provides a kind of quick locking of drum magazine, opening device, the locking system include tensing hook 1, Cover 9, dead bolt 2, attacker 3, flexible member and handle 6；Ancillary equipment is cylinder 11.

As shown in Figure 1 and Figure 2, the boss 14 for tensing hook 1 and the top of cover 9 is socketed, and the boss 14 for tensing hook 1 and cover 9 is matched somebody with somebody Close, tension hook 1 is rotated around the boss 14 of cover 9, and it is spacing by anti-loosing screw 7；Handle 6 passes through pin with tensing hook 1 Axle screw 8 is rotatablely connected, and the junction of handle 6 is cam structure, and handle 6 rotates around junction makes cam structure compression and open end can Lid 9；The one end of attacker 3 is rotatablely connected with the end of handle 6, and rotation direction is consistent with the rotation direction of handle 6, and the other end of attacker 3 leads to Cross dead bolt 2 to hook 1 with tensing and coordinate, tense and hook 1 and be provided with the lockhole 12 that is engaged with dead bolt 2, flexible member be arranged on handle 6 with Between attacker 3.

The present embodiment elastic element is torsion spring 4, and torsion spring 4 is rotatably assorted by torsion spring bearing pin 5 and handle 6, torsion spring 4 one Supporting leg coordinates with handle 6, and 4 another supporting legs of torsion spring coordinate with attacker 3, and dead bolt 2 is spacing in tension hook by the active force of torsion spring 4 In 1 lockhole 12.

Preferably, the inside of cover 9 is provided with sealing ring 10 with the contact position of cylinder 11, and sealing ring 10 passes through after the compression of handle 6 Deformation reaches sealing effectiveness.

It is as shown in Figure 3 to seal locking process：Cover 9 aligns cylinder 11, and rotation, which tenses, hooks 1 until tensing hook 1 and cylinder 11 On limiting stand 13 be engaged, rotate down handle 6, the downward hold-down barrel 11 of cover 9, while dead bolt 2 torsion spring 4 effect under, Hook 1 along tensing and glide, tensed until dead bolt 2 slides into the lockhole 12 for hooking 1, at the same dead bolt 2 by the active force of torsion spring 4 it is spacing Tense in the lockhole 12 for hooking 1, prevent cover 9 from voluntarily opening, the hold-down barrel 11 of cover 9, while sealing ring 10 after the compression of handle 6 By deforming and sealing cover 9.

Opening process is as shown in Figure 4：During unlatching, power is acted on attacker 3, and external force effect makes dead bolt 2 complete with tensing hook 1 Disengage, continue to exert oneself, until completely disengaged；Compression of the handle 6 to cover 9 is released simultaneously, and rotation, which tenses, to be hooked on 1 and cylinder 11 Limiting stand 13 staggers, and cover 9 is opened.

To sum up, the locking of drum magazine, unlatching operational motion are single, can be rapidly completed by rotating handles, can be effective Prevent maloperation, reduce the operating time, and make structure more solid and reliable with the cooperation of dead bolt, in transit also will not be with Meaning disengages.

In summary, preferred embodiment of the present utility model is these are only, is not intended to limit of the present utility model Protection domain.All any modification, equivalent substitution and improvements within the spirit and principles of the utility model, made etc., all should be wrapped It is contained within the scope of protection of the utility model.
