Description

Saw bow folding and unfolding stroller

Technical field

The utility model belongs to work, amount, fixture putting equipment, and in particular to a kind of saw used in student's fitter training Bend folding and unfolding stroller.

Background technology

Sawing is a basic skills of pincers worker, and the instrument of sawing is saw bow.In the incipient stage of practical teaching, due to learning It is raw it is proper use of to instrument, put and the consciousness of maintain is not yet firmly established, it is more to simultaneously participate in the quantity of real training student, instructs to teach Teacher's task is heavy, often occurs that saw bow is arbitrarily put, or even has the part being discarded in saw bow in scrap heap or by saw bow Take the phenomenon in real training workshop out of, this quantity and its integrity of discrimination that are both not easy to check saw bow, be also unfavorable for keeping specification Teaching behavior is with performing effective management system.

The content of the invention

The purpose of this utility model is to provide a kind of simple in construction, folding and unfolding and conveniently moving and the saw for being easy to check quantity Bend folding and unfolding stroller.Saw bow that it effectively can solve to occur in background technology can not specification put and cause to use and managerial confusion Technical problem.

To reach above-mentioned purpose, the technical solution of the utility model, it includes mobile wheel assembly, support section and folding and unfolding bar Component, described mobile wheel assembly include movable pulley and mobile wheel support, and described movable pulley is fixed on by mobile wheel support The lower end of support section；Described support section includes four connecting rods and four cradling pieces, between described four cradling pieces It is parallel to each other and lower end is connected by four connecting rods；It is equidistant horizontal provided with some set folding and unfolding bar groups on described cradling piece Part, described every suit folding and unfolding bar assembly include fix bar, put bar and support bar, described support bar be arranged on cradling piece it Between, described fix bar and put bar and be fixed by screws on support bar, described fix bar and put bar correspondence position On be respectively equipped with several standing grooves one and standing groove two；The lower section of described standing groove two is provided with Sign Board.

In the above-mentioned technical solutions, described movable pulley is universal wheel.

After adopting the above technical scheme, the coding of the two digits such as 01,02,03 can be set on coding board, the coding can be with The rear two digits of student's student number are corresponding, i.e. every student uses and put the saw on coding board consistent with oneself student number Bow, such teacher or experiment management personnel be easy to check saw bow whether reclaim it is complete, using whether intact；Again just simultaneously In mobile real training instrument, the labor intensity that practice instruction teacher careful preparation works can be mitigated.

Embodiment

A kind of saw bow folding and unfolding stroller of the utility model is described further below in conjunction with the accompanying drawings：As seen from Figure 1, this practicality It is new it include mobile wheel assembly 1, support section 2 and folding and unfolding bar assembly 3, described mobile wheel assembly 1 and include the He of movable pulley 11 Mobile wheel support 12, described movable pulley 11 are fixed on the lower end of support section 2 by mobile wheel support 12；Described supporting part Divide 2 to include four connecting rods 21 and four cradling pieces 22, be parallel to each other between described four cradling pieces 22 and lower end is by four Branch connecting rod 21 is connected；Equidistant horizontal provided with some set folding and unfolding bar assemblies 3 on described cradling piece 22, described every suit is received Putting bar assembly 3 includes fix bar 31, puts bar 32 and support bar 33, and described support bar 33 is arranged between cradling piece 22, institute The fix bar 31 stated and put bar 32 and be fixed on by screw 4 on support bar 33, described fix bar 31 and to put bar 32 right Answer and several standing grooves 1 and standing groove 2 35 are respectively equipped with position；The lower section of described standing groove 2 35 is provided with Sign Board 5。

Application method of the present utility model is that Sign Board 5 is first taken turns doing into upper two digits from left to right, from the top down Numbering, the coding with the identical two digits of Sign Board 5 is also identified in the lever side of saw bow, by saw bow according to coded sequence successively It is placed in standing groove 1 and standing groove 2 35, one end of lever is placed on the side of standing groove 2 35.During training operation, learn Life can take the saw bow encoded with Sign Board 5 on opposite position according to itself student number；After real training terminates, as long as student is by used in Saw bow is correctly placed in standing groove 1 and standing groove 2 35, and whether real training teacher or Experimental Management personnel are very easy to find saw bow Reclaim complete, or even quickly confirm that the saw bow of who student is not submitted or correctly put.

In the present embodiment, in order to move conveniently, the lower end of described support section 2 is provided with mobile wheel assembly 1, described Mobile wheel assembly 1 includes movable pulley 11 and mounting bracket 12, and further, described movable pulley 11 is universal wheel.

The utility model can save real training teacher because distributing and collecting the time shared by instrument；Prevent student's destruction occur Or tool of not handing over the problem of can not tracing people；Can canonical teaching management, be advantageous to instrument putting on shelf again, save pendulum Between emptying.
