Description

The tool box

Technical field

The utility model relates to a kind of tool box, particularly a kind ofly lays used depositing various power tools, be equipped with the tool box of accessory etc. such as various circuits such as motor vehicle repair, equipment maintenance, instrument and meter maintenance, field.

Background technology

In the maintenance of the maintaining of motor vehicle repair, enterprise's workshop appliance, instrument and meter, lay various circuits or the like and generally all used the tool box, deposit various tool in the tool box categorizedly and deposit part securing member commonly used fully, be equipped with accessory, this brings great convenience to the mechanic.Yet existing tool box has exposed some deficiency in actual use, and the door that mainly shows as the tool box can occupy very big space when outwards opening, and this is very disadvantageous for the occasion that some working space is restricted.So people have just expected chamber door is designed to folded form naturally, whole fan chamber door is divided into two from central authorities, with hinge realization connection each other, under user mode, they are amounted to, take up space in order to saving the institute of chamber door when opening.Though scheme is feasible, but the door that is folded can't maintain folding power between the two, tend to occur still bring inconvenience from the situation of expansion mutually to the user from collapsing or claiming; No matter be when unlatching is folding in addition, still when launching to close, phenomenon is hit in appearance easily, and the protection of opposite house body and chamber door doorframe is unfavorable.

Summary of the invention

No matter task of the present utility model is to provide a kind of chamber door that can make opening and be closing or can not occurring hitting the tool box of phenomenon when opening chamber door of the certain clamping force of maintenance under the folded state.

Task of the present utility model is finished like this, a kind of tool box, it comprises casing, chamber door, walking mechanism, characteristics are: it also includes the chamber door fold mechanism that connects between chamber door and casing, this mechanism comprises spring dead plate 6, spring lever cover 4, spring reed 3, spring 5, spring lever fixed head 6 is fixed on the chamber door, spring lever cover 4 cavity volumes 7 with a hollow, one end is connected with spring lever fixed head 6, one end of the spring lever 3 in its cavity volume 7 of the other end and insertion matches, the other end hub setting of spring lever 3 is on casing, and spring 5 is installed with in the cavity volume 7 of the described hollow of spring lever cover 4, and with the preceding end in contact that is inserted into the spring lever 3 in the cavity volume 7.

Spring lever 3 described in the utility model is installed with a spring reed joint 2 in the end of hub setting at it mutually with casing, and spring bar connection 2 articulates with the doorframe of casing.

The utility model can guarantee that chamber door has certain support power opening and be under the folded state, closing/impingement phenomenon can not occur when opening chamber door.

Accompanying drawing and drawing explanation

Fig. 1 is an example structure figure of the present utility model.

The state that Fig. 2 is showed when chamber door is opened for chamber door fold mechanism of the present utility model.

The state that Fig. 3 is showed when chamber door is closed for chamber door fold mechanism of the present utility model.

The specific embodiment

Among Fig. 1, illustrated a kind of cordwood tool box, be the structure form of expression of whole box body be divided into left and right casing 24,19, middle housing 15,15 ', by left and right casing 24,25, middle housing 15,15 ' set constitute a complete casing.Because this figure only is a kind of form that the applicant lifted, so the form of expression of casing is not subjected to the concrete restriction of structure shown in this figure.And, it is that example is provided with the chamber door fold mechanism that the applicant has selected with the door on the middle housing 15 in the figure, door on the middle housing 15 is made of last, folding

door

12,13, and will to go up the chamber door frame 10 of folding door 12 and middle housing 15 hinged by defaulting in hinge 14 on folding door 12 and the middle housing 15 respectively with hinge axis 16.And also be hinged by folding hinge 11 by the same manner between the upper and

lower folding door

12,13, and also being equipped with a pair of handle 17 in following folding door 13 inclined to one side both sides, the middle part is provided with door lock 20, and door lock 20 is done the time spent, can make lock pin 18 lock/withdraw from lockpin hole 8.Consider the effect equilibrium of forces, the utility model connects the chamber door fold mechanism respectively at the following two ends of folding door 13, because structure, the action principle of the chamber door fold mechanism at two ends are on all four, so the applicant selects one and carries out detailed narration.The base portion of spring lever fixed head 6 is fixed on down on the folding door 13, and leading section ammunition feed spring base cover 4 fixes with it, cavity volume 7 contents of spring lever cover 4 are gone into spring 5. after holding to go into spring 5, with an end inserting of spring lever 3 in cavity volume 7, the other end of spring lever 3 is cardinal extremity also is hinged to chamber door frame 10 belows of middle housing 15 with screw axis 1 by spring bar connection 2 case oral area position, specifically be that case oral area position below chamber door frame 10 is fixed with a spring pole socket 9, bolt was gone into to spring pole socket 10 again after screw axis 1 is passed through screw axis hole in the spring bar connection 2, had realized that just spring lever 3 is with doorframe 10 mutually and hinged.

By the description of the utility model, be appreciated that out that fully it also is feasible that the chamber door on the left and right casing 24,19 is provided with aforesaid chamber door fold mechanism to the front.Described walking mechanism comprises handle 21, the wheel 23 of being with steering mechanism 22.

Among Fig. 2 and Fig. 3, be the example explanation with Fig. 2 earlier, opened upper and lower folding door at 12,13 o'clock, as long as earlier door lock 20 is opened, make its lock pin 18 recess lockpin hole 8, act on handle 17 with hand again and also upwards guide and support, upper and

lower folding door

12,13 folds, in folding process medi-spring 5 compression,, make upper and

lower folding door

12,13 folding backs keep the support power and can not scatter by the effect of spring lever 3.The residing closed condition of Fig. 3 is by obtaining with aforementioned opposite action.
