Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further, understands the utility model technical thought required for protection so that clearer.
As shown in Figure 1, 2, be a kind of Novel draw-bar box of the present utility model, comprise casing 1, be arranged on telescopic lever on casing 1, be arranged on the roll wheel assembly 2 on casing 1 bottom; On the bottom of described casing 1, be provided with connecting axle 4, on this connecting axle 4, radially offer mounting groove, in this mounting groove, be movably installed with the pressing piece 5 that can move along its bearing of trend, and between pressing piece 5 and the medial extremity of mounting groove, spring is installed; Described roll wheel assembly 2 comprises for being sleeved on support 22 on connecting axle 4, being arranged on the roller 21 on support 22 by rotating shaft; On the sidewall of described support 22, be provided with the perforation 23 of stretching out for the outboard end of pressing piece 5.Concrete, four end angle places of described casing 1 bottom are all provided with roll wheel assembly 2.
Concrete, on described connecting axle 4, show at least two mounting grooves around its axis circumferential row.And preferred, on described connecting axle 4, show two mounting grooves around its axis circumferential row, to reduce its processing cost.
Concrete, described pressing piece 5 also comprise be positioned at mounting groove location division, be arranged on the head of pressing on outside, location division; The described area of section of pressing head is less than the area of section of location division.And by the structure of pressing piece 5 is rationally set, can be convenient to processing and fabricating, be conducive to reduce cost of manufacture.
Preferably, on described connecting axle 4, offer along its axially extended locating slot, on the madial wall of described support 22, be provided with for being embedded in the positioning convex column in this locating slot.And by adopting the structure of locating slot and positioning convex column, can be convenient to the installation location of support 22, and can improve the installation effectiveness of support 22, also can make support 22 more stable with being connected of connecting axle 4.Concrete, on described connecting axle 4, show two locating slots around its axis circumferential row, the quantity of the positioning convex column on described support 22 is consistent with the quantity of the locating slot on connecting axle 4, and corresponding one by one.
