Abstract
The utility model discloses a kind of fire-extinguishing shell launcher and launch cover, comprise body, described body outer wall is provided with cannelure, be provided with C type in described cannelure to encircle and two contacts, the internal diameter that described C type is encircled is less than the diameter of annular groove bottom arc surface, the two ends that C type is encircled compress corresponding contact respectively, and C type is encircled and undertaken being connected locking by lock-screw between cannelure, and described two contacts all stretch in body through cover body wall.The fire-extinguishing shell launcher of this structure launches cover, has that volume is little, lightweight, contact good fixing effect and an advantage of convenient disassembly.
Description
Technical field
The utility model relates to fire distinguisher technical field, is specifically related to a kind of fire-extinguishing shell launcher and launches cover.
Background technology
Fire extinguishing occupies very consequence in whole world economy, forest fire, prairie fire, oil tank catch fire and high-rise fire every year to China and human society cause direct, indirectly economic loss be all unable to estimate.
In the prior art; in order to more protect the personal safety of fire extinguishing personnel; have employed a kind of fire-extinguishing shell launcher to put out a fire; extinguish material is filled in bullet; utilize the form of mortar or rocket launcher to be transmitted in the scene of a fire by extinguish material, protect the personal safety of fire extinguishing personnel fully.Current fire-extinguishing shell launcher, comprise gun barrel and the transmitting cover being arranged on gun barrel tail end, described transmitting cover comprises body, is detachably provided with two contacts in body, and described contact is electrically connected with percussion lock by lead-in wire.During transmitting, two contacts of fire extinguisher bomb tail end respectively with corresponding contact, the cocking circuit of then conducting percussion lock, can launch fire extinguisher bomb.Existing transmitting cover, contact dismounting is inconvenient, and simultaneously for ensureing the fixed effect of contact, usual volume is large, and weight is large, and in addition, service time is of a specified duration, and contact easily loosens, and makes contact and poor contact of contacts, thus affects the reliability of percussion process.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of fire-extinguishing shell launcher and launches cover, makes it have that volume is little, lightweight, contact good fixing effect and the advantage of convenient disassembly.
The utility model is solved the problem by following technological means: a kind of fire-extinguishing shell launcher launches cover, comprise body, described body outer wall is provided with cannelure, be provided with C type in described cannelure to encircle and two contacts, the internal diameter that described C type is encircled is less than the diameter of annular groove bottom arc surface, the two ends that C type is encircled compress corresponding contact respectively, and C type is encircled and undertaken being connected locking by lock-screw between cannelure, and described two contacts all stretch in body through cover body wall.
Further, described C type is encircled and is made up of elastomeric material.
Further, described contact is symmetrical arranged.
The beneficial effects of the utility model: fire-extinguishing shell launcher of the present utility model launches cover, comprise body, described body outer wall is provided with cannelure, be provided with C type in described cannelure to encircle and two contacts, the internal diameter that described C type is encircled is less than the diameter of annular groove bottom arc surface, the two ends that C type is encircled compress corresponding contact respectively, and C type is encircled and undertaken being connected locking by lock-screw between cannelure, and described two contacts all stretch in body through cover body wall.The fire-extinguishing shell launcher of this structure launches cover, has that volume is little, lightweight, contact good fixing effect and an advantage of convenient disassembly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that bowing of Fig. 1 sees schematic diagram.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail, as shown in Figure 1-2: a kind of fire-extinguishing shell launcher launches cover, comprise body 1, described body outer wall is provided with cannelure 2, be provided with C type in described cannelure and encircle 3 and two contacts 4, the internal diameter that described C type is encircled is less than the diameter of annular groove bottom arc surface, the two ends that C type is encircled compress corresponding contact respectively, C type is encircled and is undertaken being connected locking by lock-screw 5 between cannelure, lock-screw is usually arranged on C type and encircles position placed in the middle, C type is encircled and is made up of elastomeric material, described two contacts all stretch in body through cover body wall, described contact is symmetrical arranged.The fire-extinguishing shell launcher of this structure launches cover, the internal diameter encircled due to C type is less than the diameter of annular groove bottom arc surface, can not fit tightly so C type is encircled with annular groove bottom, in the process of tightening lock-screw, prestressing force can be produced, make C type encircle two ends and have the trend compressing contact all the time, therefore the fixed effect of contact can be ensured, and only need unclamp a lock-screw, take off C type to encircle and contact can be taken off, convenient disassembly, in addition, fixed contact in this way, compact conformation, fixing reliable, the whole volume and weight launching cover can be reduced, transmitting cover is made to have volume little, lightweight advantage.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
