Description

Strongbox

Technical field

The utility model relates to a kind of strongbox.

Background technology

At present, the casing of strongbox is by after plate cutting, housing is welded by three blocks of sheet materials, casing is formed after base plate, rear plate and door frame welding being got on again subsequently, when welding adjacent two boards material, need fixture by after spacing for two boards material, again to joint place integral solder, it is longer just to there is welding interval in this, the problem that production efficiency is slower, and the problem of rosin joint easily appears again in integral solder simultaneously, higher to welding requirements, and just product will be caused defective once rosin joint, yield rate reduces, thus causes cost higher.

Utility model content

The utility model provides for above problem the strongbox that a kind of welding is easier, welding quality better, welding interval is shorter and yield rate is higher.

The utility model overcomes the above problems technical scheme used: provide a kind of strongbox with following structure, it comprises the latch mechanism on casing and casing, described casing comprises both sides and is provided with the housing of crimp and sheet material combines, described sheet material is connected with housing by spot welding, and the crimp on sheet material and housing is fitted.

After adopting above structure, compared with prior art, the utility model is owing to have employed the housing of crimp, only need be connected with housing by spot welding after sheet material and crimp are fitted, the requirement of casing bulk strength can be realized, during welding, directly fit in the edge of sheet material and crimp by workman, and prop up can weld with hand, no longer need original welding jigs and fixtures, then ensureing under the prerequisite that casing bulk strength requires, significantly reduce the welding difficulty of casing, weld easier, and significantly can shorten welding interval, and pad is in inner walls, when follow-up spraying paint, first polish without the need to butt welding point, directly enter floating, spray mo(u)lding, production efficiency is significantly improved, spot welding is simultaneously not easy the situation occurring rosin joint, and welding quality easily controls, and the yield rate of product is also significantly improved thereupon, finally significantly reduces the cost of production of product.Therefore the utility model has the advantages that welding is easier, welding quality better, welding interval is shorter, yield rate is higher and cost of production is lower.

As improvement, described housing is U-shaped structure, and described housing both sides are the crimp of 180 degree, and described sheet material is divided into base plate, rear plate and doorframe, and described base plate is connected with two free end spot welding of housing; Described rear plate and doorframe are positioned at housing and fit with the crimp of housing both sides respectively, and are connected with inner walls spot welding; Then after this vibrational power flow, not only the intensity of housing is better, and the bonding strength of crimp and sheet material point postwelding is also higher, also reduces the quantity of integral solder, the yield rate of further production efficiency and product, thus reduces production cost further.

As further improvement, described housing is L font structure, and described housing is two pieces, thus sheet material be divided into rear plate and doorframe, described housing both sides are the crimp of 180 degree, and the head and the tail of two pieces of housings are welded to each other formation loop configuration; Described rear plate and doorframe are positioned at the two ends of loop configuration, and fit with each self-corresponding crimp respectively, and are connected with inner walls spot welding; Then after this vibrational power flow, no longer include independent base plate, and housing does not need classification storage yet, be convenient to the assembling of workman, and housing makes sheet material four limit be spot welding, further can enhance productivity and the yield rate of product, thus further reduce production cost.

As improving further again, described latch mechanism comprises lock core and banking stop, described lock core is fixed on casing, the position that described casing internal cylinder is corresponding is provided with support, described banking stop slides up and down and is connected on support, and the middle part of banking stop is provided with waist-shaped hole, the length direction of described waist-shaped hole is mutually vertical with the length direction of banking stop, and one end that described lock core is positioned at casing is provided with the driving lever stirred banking stop and slide up and down; Then such latch mechanism structure is comparatively simple, and component are less, and preparation cost is lower, and dependability is better simultaneously, and durability degree is also higher, and then ensures application life of the present utility model.

As further improving, described support is provided with connecting hole, and the two ends up and down of support are equipped with flat board, described flat board is equipped with slide opening, the length of described banking stop is greater than the spacing between two flat boards, and described support is socketed in by connecting hole one end that lock core is positioned at casing, and described banking stop is slidably connected in slide opening, and banking stop upper end is provided with the bending for lower limit, one end bias that described driving lever and lock core are positioned at casing is connected; Then can reduce mobilizable parts further like this, thus ensure mechanism's stability in use and reliability, and reduce the wearing and tearing between each parts, and then extend application life of the present utility model.
