Embodiment 1

[0030] Refer to attached figure 1 , a simple and foldable rest device, including a fixed clamping mechanism 1, a folding mechanism 2 and a plurality of support rods 3, wherein the fixed clamping mechanism 1 is used to fix the rest device and a support, and the support refers to an existing Trees, street lamps, etc., so that the device can be installed and fixed relying on the existing structure. Specifically, the fixed clamping mechanism 1 includes a fixed ring 11 and a clamping piece 12. The fixed ring 11 is two semi-annular metal rings. Fastened on the support, and the fastening is done by means of the clamping piece 12.

[0031] The above-mentioned clamping member 12 can be selected from bolts, which are used in conjunction with the screw holes at both ends of the metal ring.

[0032] The fixed clamping mechanism 1 is arranged above the folding mechanism 2 , specifically fixed on the uppermost scissors structure 21 of the folding mechanism 2 . The folding mechanism 2 is c...

Embodiment 2

[0036] Refer to attached figure 2 , a fixed clamping mechanism 1 that can be applied in Embodiment 1. The fixed clamping mechanism 1 includes a fixed ring 11 and a clamping member 12. The fixed ring 11 is two semi-circular metal rings, and the rest device is fixed on the support by means of bolt fastening.

[0037] In order not to damage the fixing ring 11 and the clamping piece 12, a rubber ring 13 with a semi-annular structure is arranged inside the metal ring. A corresponding protruding ring is provided on the outer side of the semi-circular rubber, and when in use, through the cooperation of the annular groove and the protruding ring, a certain buffer is formed and the stability of the fastening structure can be improved.

[0038] Refer to attached Figure 4 , a schematic diagram of the connection structure between the support rod 3 and the folding mechanism 2 . The support rod 3 is a foldable structure, which is movably connected with the folding mechanism 2 through a...

Abstract

The invention discloses a simple and foldable rest device. The rest device comprises a fixing and clamping mechanism, a folding mechanism and a plurality of support rod pieces, wherein the fixing and clamping mechanism comprises a fixing ring and a clamping part and is used for fixing the rest device with holders; the folding mechanism comprises a plurality of shear fork structures and an I beam for fixing the use state; the support rod pieces are used for mounting a shading article; the fixing and clamping mechanism is fixedly connected with the uppermost shear fork structure, and the support rod pieces are arranged at all ends of the folding mechanism and movably mounted with the folding mechanism. By the aid of the rest device, a simple sanitation worker rest place which is high in space utilization rate and foldable is realized. The device takes roadside street lamps and trees as holders, the space is utilized effectively, the rest device can be quickly opened when used and can be folded and hung on the holders when not used, and the rest device is low in cost, does not affect the appearance of a city and is convenient to implement.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a foldable on-site simple rest device for sanitation workers with high space utilization. Background technique [0002] At present, sanitation workers have five major problems: "difficulty eating, drinking water, rest, going to the toilet, and seeking medical treatment". For sanitation workers to rest, there are only some rest booths and love stations on the street that can provide sanitation workers with rest places. However, sanitation workers have a relatively large work scope and strong mobility, and they need a dense distribution of restrooms to meet their needs. . The rest pavilion or love station has the characteristics of large area and long construction period. It is unrealistic to build a large number of intensive buildings. This leads to the fact that the number of restrooms for existing sanitation workers is far from enough to meet the needs of sanitation wor...
