Description

Temporary protective fence

Technical Field

The utility model relates to the technical field of protective fences, in particular to a temporary protective fence.

Background

When repairing municipal road, need use temporary guard rail for isolated pedestrian, vehicle, protection constructor simultaneously, in order to make things convenient for temporary guard rail's installation and transportation, temporary guard rail not only needs simple structure, should possess collapsible ability simultaneously, reduces the occupation of transportation space.

The prior art has the following publication numbers: the municipal engineering temporary protective fence convenient to transport comprises two upright posts, wherein two upright posts for supporting the protective fence are symmetrically arranged, and the bottom ends of the upright posts are welded and fixed with mounting plates; the movable base consists of a bottom plate fixedly arranged at the bottom end of the upright post and a roller arranged at the bottom surface of the bottom plate, and can move the guard rail to achieve the aim of temporarily erecting the guard rail; and the protection rod consists of a plurality of protection inner rods and protection outer rods which are mutually intersected, and the middle positions and the two ends of the protection inner rods and the protection outer rods are movably assembled together through connecting rotating shafts.

Above-mentioned equipment is when the transportation, and equipment is placed in the carriage, because the use of gyro wheel, when the vehicle received jolting, the gyro wheel took place to rotate, leads to equipment to launch automatically, takes place the striking easily, causes the damage to equipment.

Disclosure of Invention

(one) solving the technical problems

In order to solve the problems in the prior art, the utility model provides a temporary protective fence which can prevent equipment from being automatically opened in the transportation process and ensure the transportation stability of the equipment.

(II) technical scheme

In order to achieve the above purpose, the main technical scheme adopted by the utility model comprises the following steps:

the utility model provides a temporary protective fence, includes the folding fence that is located the first bracing piece of left side position, is located the second bracing piece of right side position, position between first bracing piece and the second bracing piece, the mount is all installed to first bracing piece and second bracing piece bottom position, the gyro wheel is installed to the mount bottom, the go-between is installed in rotation of first bracing piece top one end, second bracing piece outer wall upper portion position is provided with the stop gear who uses with the go-between cooperation. Can effectively avoid equipment to expand automatically when transporting, the stability of equipment when guaranteeing the transportation.

Preferably, the limiting mechanism comprises a groove arranged at the outer wall of the second supporting rod, a limiting block rotatably arranged in the groove and a spring arranged between the limiting block and the inner wall of the groove.

Preferably, the outer wall of one side of the limiting block far away from the groove is of an arc-shaped structure, and the bottom of the limiting block protrudes out of the groove.

(III) beneficial effects

The utility model provides a temporary guard rail. The beneficial effects are as follows:

(1) Through the use of go-between and stop gear, can be to first bracing piece and second bracing piece interconnect, avoid equipment when the transportation, automatic expansion.

(2) When the connecting ring rotates, the connecting ring is clamped by the bottom of the limiting block, the first supporting rod and the second supporting rod are mutually connected, the middle part of the limiting block is pressed, the limiting block is pressed into the groove, then the connecting ring is turned over, the first supporting rod and the second supporting rod can lose limiting, and then the unfolding equipment is used.

Drawings

FIG. 1 is a block diagram of the present utility model;

fig. 2 is a block diagram of a spacing mechanism according to the present utility model.

In the figure: 1. a first support bar; 2. a second support bar; 3. folding the fence; 4. a fixing frame; 5. a roller; 6. a connecting ring; 7. a limiting mechanism; 8. a groove; 9. a limiting block; 10. and (3) a spring.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-2, the temporary guard rail of the embodiment comprises a first support rod 1 positioned at a left side, a second support rod 2 positioned at a right side, and a folding fence 3 positioned between the first support rod 1 and the second support rod 2, wherein fixing frames 4 are respectively arranged at the bottom positions of the first support rod 1 and the second support rod 2, rollers 5 are arranged at the bottoms of the fixing frames 4, and the rollers 5 are used to facilitate the movement of equipment. The top one end of the first support rod 1 is rotatably provided with a connecting ring 6, and a limiting mechanism 7 matched with the connecting ring 6 for use is arranged at the upper part of the outer wall of the second support rod 2. When accomodating equipment, folding fence 3, first bracing piece 1 is close to second bracing piece 2, then rotates go-between 6, and go-between 6 embolias second bracing piece 2 from second bracing piece 2 top, realizes being connected to head rod 1 and second connecting rod 2, cooperates stop gear 7 to carry out spacingly to go-between 6 simultaneously, can avoid go-between 6 automatic opening.

Further, the limiting mechanism 7 comprises a groove 8 formed in the outer wall of the second supporting rod 2, a limiting block 9 rotatably mounted in the groove 8 and a spring 10 arranged between the limiting block 9 and the inner wall of the groove 8. The spring 10 ejects the limiting block 9 to limit the connecting ring 6.

Further, the outer wall of one side of the limiting block 9, which is far away from the groove 8, is of an arc-shaped structure, and the bottom of the limiting block 9 protrudes out of the groove 8.

Working principle: when equipment is required to be folded, the folding fence 3 is folded, the first supporting rod 1 is close to the second supporting rod 2, then the connecting ring 6 is rotated, the connecting ring 6 is sleeved into the second supporting rod 2 from the top of the second supporting rod 2, the connecting ring 6 can press the limiting block 9 to rotate when being sleeved into the second supporting rod 2, the limiting block 9 presses the spring 10 to deform, when the connecting ring 6 rotates to a limiting position, the limiting block 9 loses the pressing of the connecting ring 6 and resets under the action of the spring 10, the limiting block 9 realizes the limiting of the connecting ring 6, meanwhile, the limiting block 6 is limited by the limiting mechanism 7, the connecting ring 6 can be prevented from being automatically opened, when the equipment is required to be unfolded, the middle part of the limiting block 9 is pressed, the limiting block 9 rotates to press the spring 10 to deform, the limiting block 9 rotates into the groove 8, then the connecting ring 6 rotates, the connecting ring 6 rotates out of the top of the second supporting rod 2, and the folding fence 3 is unfolded.
