Specific embodiment

To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below In conjunction with specific embodiment, the utility model is further described.

In this application unless specifically defined or limited otherwise, term " connection ", " fixation " shall be understood in a broad sense, example Such as, it may be a fixed connection, may be a detachable connection, or is integral；It can be mechanical connection, be also possible to be electrically connected； It can be directly connected, the connection inside two elements or two elements can also be can be indirectly connected through an intermediary Interaction relationship.For the ordinary skill in the art, above-mentioned term can be understood at this as the case may be Concrete meaning in invention.

As shown in Figure 1-3, the utility model provides a kind of construction engineering cost tool box, including cabinet 10 and case lid, The both ends of the bottom of the cabinet 10 are respectively arranged with a foldable supporting leg 20.

Every supporting leg 20 include the cross bar 21 that a middle part is connect with the lower rotation of cabinet 10 and two respectively with it is described The length of the vertical bar 22 that the both ends of cross bar 21 are fixedly connected, the cross bar 21 in two supporting legs 20 is not identical, in this way when two supporting legs After 20 foldings are got up, the vertical bar 22 in two supporting legs 20 can be staggered, that is to say, that the active rail of the vertical bar 22 in two supporting legs 20 The part that mark does not intersect.Every vertical bar 22 includes first body of rod 221, one end and the institute that one end is fixedly connected with the cross bar 21 State the second hinged body of rod 222 of the other end of first body of rod 221 and when first body of rod 221 and second body of rod 222 First body of rod 221 and second body of rod 222 is set to keep conllinear holding meanss, the length of first body of rod 221 when conllinear The distance between both ends of bottom of cabinet 10 are adapted, and the length of such first body of rod 221 can maximize, similarly, by It can get up relative to first body of rod, 221 folding in second body of rod 222, therefore the length of second body of rod 222 and first body of rod 221 Similar length.In this way when first body of rod 221 and conllinear second body of rod 222, i.e., vertical bar 22 be in line shape when, the length of vertical bar 22 Degree is maximum.

The bottom of cabinet 10 is additionally provided with the limiting device 30 of the tilt angle for limiting the vertical bar 22 and works as institute State the cover board 40 being detachably connected with the cabinet 10 that the supporting leg 20 is covered when 20 folding of supporting leg is got up.When cabinet 10 After the two supporting legs 20 of bottom are unfolded, supporting leg 20 is set to have a certain degree inclination by limiting device 30, at this time two supporting legs 20 It is distributed at "eight" shape, such two supporting legs 20 can provide reliable support to cabinet 10.After supporting leg 20 is unfolded, the height of cabinet 10 Degree is raised, so as to facilitate engineering cost personnel to map on it.After 20 folding of supporting leg is got up, supporting leg 20 againsts case Then cover board 40 is covered the lower section of the supporting leg 20 to get up in folding by the bottom of body 10.It is preferred that cover board 40 is slidably connected with cabinet 10, A sliding slot 11 is had on two opposite side walls of cabinet 10, cover board 40 can be pacified in the mode being inserted into sliding slot 11 Mounted in the lower end of cabinet 10.Cover board 40 is used to that the supporting leg 20 after folding to be made to keep folding state, the i.e. presence due to cover board 40, branch Leg 20 will not be unfolded under the effect of gravity, unless cover board 40 is removed.

As a further improvement of the foregoing solution, the holding meanss include one being set on first body of rod 221 Keep set 223 and one be fixed at second body of rod 222 described one end block 224, holdings covers 223 can be along institute The length direction for stating first body of rod 221 is slided and can be covered simultaneously outside first body of rod 221 and second body of rod 222, is protected The part that set 223 can be hinged by first body of rod 221 and second body of rod 222 in sliding process is held, keeps set 223 can in this way To be slided on second body of rod 222 from first body of rod 221.It keeps set 223 when sliding to second body of rod, 222 direction, works as guarantor When holding set 223 cannot further be slided by the blocking of the block 224 on second body of rod 222, set 223 is kept both to cover at this time Outside second body of rod 222, and cover outside first body of rod 221, such second body of rod 222 cannot around with first body of rod 221 it is hinged in The heart is swung, and second body of rod 222 and first body of rod 221 are conllinear.At "eight" shape after being unfolded due to supporting leg 20, set 223 is kept Can be maintained under self gravitation effect makes on first body of rod 221 and the conllinear position of second body of rod 222.Above-mentioned holding meanss, Structure is simple, easy to use.

As a further improvement of the foregoing solution, the limiting device 30 is arranged in a one-to-one correspondence with the vertical bar 22, that is, is limited There are four position device 30 is correspondingly arranged.The pedestal 31 of bottom of the limiting device 30 including being fixed at the cabinet 10, The sliding block 32 and one for being slidably arranged in the bottom of the cabinet 10 connect across the pedestal 31 and with 31 screw thread of pedestal The screw rod 33 connect, one end of the screw rod 33 is abutted with the sliding block 32, the other end is provided with one handle 34.When supporting leg 20 is unfolded Afterwards, described one end (i.e. upper end) of vertical bar 22 cannot further be swung because of the blocking by sliding block 32, thus in sliding block 32 Under barrier effect, at "eight" shape after the expansion of supporting leg 20.Rotational handle 34, screw rod 33 pushes sliding block 32 mobile, so as to adjust Save the inclined degree of supporting leg 20.The structure of above-mentioned limiting device 30 is simple, adjusts very convenient.

As a further improvement of the foregoing solution, it is connected between the pedestal 31 and sliding block 32 by spring 35, spring 35 And both ends outer in screw rod 33 are covered to be fixedly connected respectively at pedestal 31 with sliding block 32.Spring 35 is tension spring, can guarantee sliding block 32 in this way It remains and abuts between screw rod 33, after supporting leg 20, which is stowed away, to be come, sliding block 32 will not be slided arbitrarily.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above, for For those skilled in the art, it is clear that the present invention is not limited to the details of the above exemplary embodiments, and without departing substantially from this In the case where the spirit or essential attributes of utility model, the utility model can be realized in other specific forms.Therefore, no matter From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the utility model is by institute Attached claim rather than above description limit, it is intended that will fall within the meaning and scope of the equivalent elements of the claims All changes are embraced therein.
