Abstract

The utility model aims to provide a trolley with foldable handles in order to solve the problem that when the existing trolley is lifted, the existing trolley is overturned due to the fact that handles of the existing trolley are intervened with other objects, and therefore safety of construction operations is ensured. The trolley with the foldable handles comprises a trolley hopper, trolley wheels and two rod-shaped handles, wherein the trolley wheels are installed below the trolley hopper, and the two rod-shaped handles are installed on two sides of the trolley hopper. The trolley with the foldable handles is characterized in that protruding bearing seats are arranged on two sides of the trolley hopper, the end portions of the foldable handles are arranged on the bearing seats through bearings which are vertically arranged, and fixing structures which are used for fixing the foldable handles are further arranged on the two sides of the trolley hopper. The trolley with the foldable handles is simple in structure, low in cost, easy to transform and convenient to use. Compared with a traditional trolley, the trolley with the foldable handles is more suitable for lifting operations, and therefore adaptability is stronger.

Description

A kind of trolley of collapsible handle

Technical field

The utility model belongs to the vehicle for construction technical field, specially refers to a kind of trolley for the shipment building material.

Background technology

In constructions work, people often use trolley to transport building materials such as sandstone, cement wash.Trolley relies on manual operation fully, though control is convenient, flexible, but people can't directly be delivered to trolley on the high building of building together with the building material on it, must adopt elevator or rope to wait trolley is promoted to required floor, in this process the handle of trolley easily and other objects interfere, cause trolley to topple, bring danger for the workmen of aloft work and below.

Summary of the invention

The purpose of this utility model is the trolley that proposes a kind of collapsible handle, to avoid when promoting trolley the trolley handle and to interfere with other objects, causes trolley to topple, and then guarantees the safety of construction operation.

The trolley of collapsible handle of the present utility model comprises wagon box, is installed on the wheel of wagon box below and two shaft-like handles that are installed on the wagon box both sides, key is that the both sides of described wagon box are provided with outstanding bearing seat, the end of described handle is installed on the described bearing seat by vertically disposed bearing, and the both sides of described wagon box also are provided with the fixed sturcture for fixed handle.

Handle can rotate around bearing, when needs utilize handle to promote trolley, handle can be turned to a side of wagon box like this, and this moment, bearing can fix handle in the handle horizontal direction, to transmit handle to the horizontal thrust of trolley.When needs are put into trolley when promoting to elevator, swing handle makes handle be adjacent to the both sides of wagon box, avoids that handle and other objects interfere in the trolley lifting process, causes trolley to topple.Be in when stretching with folded state at handle, can utilize fixed sturcture to come handle is simply fixed, avoid handle to move freely.

Further, the both sides of described bearing seat are provided with the horizontal slot that can hold handle, when handle is in when stretching with folded state; handle can snap in the horizontal slot; handle stressed meeting in the vertical direction is delivered on the horizontal slot, rather than is born by bearing fully, has so just protected bearing.

Further, described fixed sturcture is vertically through pin or the bolt of horizontal slot cell wall, stretch or during folded state, can utilize pin or bolt to pass the horizontal slot cell wall when handle is in, thereby with handlebar locked in horizontal slot, realize fixing.

Further; described handle is provided with through hole in the position of corresponding pin or bolt; can utilize pin or bolt to pass the through hole of horizontal slot cell wall and handle like this and handlebar locked in horizontal slot; in fixed handle; pin or bolt can bear the power of the horizontal direction that handle transmits; thereby reduce the suffered power of bearing, further protected bearing.

Further, also fixedly there are reinforced rib or reinforced pipe in the both sides of described wagon box, to strengthen the intensity of trolley side.

The trolley of collapsible handle of the present utility model is simple in structure, cost is low, be easy to transformation, easy to use, compare traditional trolley and more be adapted to promote operation, so comformability is stronger.

Description of drawings

Fig. 2 is the structural representation of the trolley of the collapsible handle under the handle folded positions.

The specific embodiment

Contrast accompanying drawing below, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are described in further detail.

Embodiment 1:

As shown in Figure 1, 2, two shaft-like handles 3 that the trolley of the collapsible handle of present embodiment comprises wagon box 1, is installed on the wheel 2 of wagon box 1 below and is installed on wagon box 1 both sides, key is that the both sides of described wagon box 1 are provided with outstanding bearing seat 4, and the end of handle 3 is installed on the bearing seat 4 by vertically disposed bearing 5; The both sides of bearing seat 4 are provided with the horizontal slot 6 that can hold handle, horizontal slot 6 is provided with vertically the pin 7 through horizontal slot 6 cell walls, stretches or during folded state, can utilize pin 7 to pass horizontal slot 6 cell walls when handle 3 is in, thereby handle 3 is locked in the horizontal slot 6, realizes fixing.

Handle 3 is provided with through hole 9 in the position of corresponding pin 7; can utilize pin 7 to pass the through hole 9 of horizontal slot 6 cell walls and handle like this and handle 3 is locked in the horizontal slot 6; in fixed handle 3; pin 7 can bear the power of the horizontal direction that handle 3 transmits; thereby reduce the suffered power of bearing 5, further protected bearing 5.Certainly, pin 7 and through hole 9 can arrange a plurality of, to improve the effect of protection bearing 5.

Also fixedly there is reinforced rib 8 both sides of wagon box 1, to strengthen the intensity of trolley side.

As shown in Figure 1, handle 3 can rotate around bearing 5, when needs utilize handle 3 to promote trolley, handle 3 can be turned to a side of wagon box 1 like this, and the through hole 9 that recycling pin 7 passes horizontal slot 6 cell walls and handle fixes handle 3; This moment, bearing 5 and pin 7 can fix handle 3 in handle 3 horizontal directions, to transmit the horizontal thrust of 3 pairs of trolleys of handle.

As shown in Figure 2, when needs are put into trolley when promoting to elevator, swing handle 3, make handle 3 be adjacent to the both sides of wagon box 1, the through hole 9 that recycling pin 7 passes horizontal slot 6 cell walls and handle fixes handle 3, avoid in the trolley lifting process handle 3 and other objects to interfere, cause trolley to topple.

When handle 3 is in when stretching with folded state, handle 3 can snap in the horizontal slot 6, and handle 3 stressed meeting in the vertical direction is delivered on the horizontal slot 6, rather than is born by bearing 5 fully, has so just protected bearing 5.
