Description

Outdoor bench of adjustable back

Technical Field

The utility model relates to a communal facility field, concretely relates to outdoor bench of adjustable back.

Background

The bench is a product for outdoor passersby to rest, and is mainly used in parks, districts, large-scale amusement parks, shopping squares and public places. With the development of the times, park chairs have stepped into most of the small and medium-sized cities. Becomes a bright landscape in cities. Brings convenience to people and enables the environment to be more harmonious. Park chair most of them comprises chair board and back two parts, like chinese patent application No. CN201920478913.2, announces day 2019.12.31, and it discloses a comfortable type park bench that can adjust the back, relates to communal facility technical field, and it includes the diaphragm, the left surface fixedly connected with head gear of diaphragm, head gear's last fixed surface is connected with the riser, the through-hole has all been seted up to both sides around the diaphragm upper surface, be provided with the slide bar in the through-hole, the left and right sides both ends of slide bar respectively with the left and right sides face fixed connection of through-hole inner wall, the sliding sleeve has been cup jointed on the surface of slide bar. This comfortable park bench that can adjust back through setting up the handle, and handle corotation drives the rotation of second pivot, and the second pivot drives the threaded rod rotation, and the threaded rod rotation can drive the screw cap and remove left, and the screw cap drives the sliding sleeve and removes left, adjusts the riser to suitable angle and uses.

According to the technical scheme disclosed by the patent document, when a user needs to adjust the vertical plate, the vertical plate needs to be adjusted by manually rotating the handle, and after the previous user uses the vertical plate, the vertical plate cannot be automatically reset, and the next user needs to adjust the vertical plate again, so that the operation is complex.

Disclosure of Invention

The utility model provides a can self-adaptation regulation back, use comfortable outdoor bench, utilize the utility model discloses a structure, the user only need lean on can the automatically regulated back on the back when using the bench, reinforcing comfort level.

In order to achieve the above purpose, the technical scheme of the utility model is that: the outdoor bench with the adjustable backrest comprises a supporting part, a beam part, a backrest part and a seat part, wherein two ends of the beam part are respectively and fixedly connected with the supporting part, the seat part is laid on the supporting part and the beam part on two sides, the beam part is respectively and fixedly connected with the front side and the rear side of the supporting part, and the backrest part is fixedly connected with one side of the beam part;

the backrest part comprises a backup plate, a connecting part, a vertical part and an inclined part, wherein the lower end of the vertical part is vertically connected with the beam part, one end of the inclined part is fixedly connected with the beam part in an inclined mode, the inclined part is located on the front side of the vertical part, one end of the connecting part is fixedly connected with the other end of the inclined part in an inclined mode, an elastic part is arranged on one side face, close to the vertical part, of the connecting part, the other side face of the connecting part is connected with the backup plate, the other end of the elastic part is fixedly connected with the; the upper end of the vertical part is provided with an avoidance groove, the inclined part is an elastic plate, the vertical part is a fixing plate, the inclined part and the vertical part are arranged in an upward and outward inclined mode, and the upper end of the connecting part is arranged in an inclined mode towards the upper end of the vertical part;

the arrangement is that when a user bench leans against the backrest part, the connecting part on the backrest part is elastically deformed towards the avoiding groove on the vertical part due to the gravity of a human body, the elastic part is compressed, the avoiding groove on the vertical part plays a guiding role for the connecting part, the inclined part and the fixing part are obliquely arranged, so that a distance exists between the inclined part and the fixing part, when the backrest is pressed, the connecting part moves towards the fixing part to drive the inclined part to approach the fixing part, so that the height of the backrest part is adjusted, the backrest can automatically adjust the position of the backrest according to the acting force and the position of the user, if the user acts on the upper end of the connecting part greatly, the distance between the user and the backrest is possibly too close, the inclined part approaches towards the vertical part, so that the distance between the backrest part and the user is increased, the distance of the backrest is automatically adjusted, and when the user adjusts the posture, the small acting force is on the, then the distance between user and the back increases to the elastic component resume state, connecting portion and slope move to keeping away from vertical portion direction, make the user more press close to the back, have strengthened the suitability to the user.

Furthermore, the seat plate part is provided with a transverse baffle at the outermost side, and the transverse baffle is fixedly connected with the supporting parts at the two sides. Thus, the comfort of the leg of the user can be enhanced while the connection strength between the side supporting parts can be enhanced.

Further, the elastic member is a spring.

Furthermore, an avoiding opening is formed in one side, close to the backrest part, of the seat plate part. Thus, the backrest part can be easily installed.

Further, the seat board part comprises more than two strip-shaped wood boards, and gaps are arranged between the strip-shaped wood boards. Thus, the heat dissipation and drainage effects are good.

Further, rollers are arranged on two sides of the connecting portion. In this way, the frictional force between the connecting portion and the vertical portion can be reduced.

Further, the two sides of the avoiding groove are provided with sliding grooves corresponding to the rolling wheels, each sliding groove is a groove with an opening at one end and a closed end at the other end, and a first opening is arranged above each sliding groove. Like this, can strengthen the guide effect to connecting portion, and the closed groove of the other end can restrict the sliding distance of connecting portion on vertical portion, prevents to lead to the elastic component unable recovery to the elastic component pressure is too big.

Further, connecting portion are the plate body, and the both sides of plate body are equipped with the breach portion that extends to the plate body in, are equipped with the gyro wheel in the breach portion, and the outstanding breach portion in the outside edge of gyro wheel sets up, above setting is equipped with the gyro wheel in both sides breach portion, and the outstanding breach portion in the outside edge of gyro wheel sets up to prevent connecting portion and opening direct contact, lead to the problem that the slip is not smooth and easy.

Furthermore, the outer side edge of the protruding gap part of the roller is in sliding connection with the inner side wall of the sliding groove, and friction between the connecting part and the sliding groove is reduced through sliding connection.
