Description
Technical Field
The utility model relates to the technical field of household manufacturing, in particular to a simple head rest angle adjusting device.
Background
The traditional Chinese patent with the publication number of CN208784124U and the name of "an electric headrest angle adjusting mechanism" discloses an electric headrest angle adjusting mechanism which comprises a backrest frame, a headrest frame hinged to the top of the backrest frame, and an electric driving device for driving the headrest frame to swing back and forth, wherein the headrest frame comprises two headrest connecting pieces hinged to two side frames of the backrest frame through pin shafts respectively and transverse connecting rods for connecting the two headrest connecting pieces, and the bottoms of the two side frames are fixedly connected through connecting beams. The related parts are relatively more, the cost is higher, and the assembly is complicated.
Disclosure of utility model
Aiming at the defects of the prior art, the utility model aims to provide the simple head rest angle adjusting device which has the advantages of simple structure, cost reduction and convenience in assembly.
In order to achieve the above purpose, the simple headrest angle adjusting device of the utility model adopts the following technical scheme:
The utility model provides a simple and easy head rest angle adjusting device, includes the horizontal pole, is provided with a plurality of headrest board installed part on the horizontal pole, and the both sides grafting of horizontal pole has back installed part, but back installed part and horizontal pole relative rotation are provided with electric putter between back installed part and the horizontal pole of arbitrary one side for order about the horizontal pole and rotate.
Preferably, the electric push rod has only one-way thrust.
Preferably, a tension spring is arranged between the backrest mounting part on at least one side and the cross bar.
Preferably, the tension spring and the electric push rod are mounted on the same side of the backrest mounting member, and the length of the side backrest mounting member is longer than that of the backrest mounting member on the other side.
Preferably, a shaft sleeve or a bearing is arranged between the backrest mounting member and the cross bar.
Compared with the prior art, the utility model has the following advantages:
1. After the headrest plate mounting piece and the cross rod are fixedly connected, the cross rod and the backrest mounting piece are spliced to form a hinge structure, and the electric push rod is directly mounted on the backrest mounting piece on one side, so that a plurality of parts and corresponding links for screwing bolts are omitted, and the purposes of reducing cost and simplifying the assembly process are achieved.
2. The electric push rod with only one-way thrust is used, and the headrest plate is driven to reset by matching with the tension spring, so that the hand is prevented from being hurt when the headrest plate resets.
Drawings
Fig. 1 is a schematic structural view of a simple headrest angle adjustment device according to the present utility model.
Fig. 2 is an enlarged view at C of fig. 1.
The device comprises a cross rod 1, a first lug plate 11, a second lug plate 12, a headrest plate mounting piece 2, a backrest mounting piece 3, a hinge shaft 31, a hanging pin 32, a shaft sleeve 4, an electric push rod 5 and a tension spring 6.
Detailed Description
The present utility model is further illustrated in the accompanying drawings and detailed description which are to be understood as being merely illustrative of the utility model and not limiting of its scope, and various modifications of the utility model, which are equivalent to those skilled in the art upon reading the utility model, fall within the scope of the utility model as defined in the appended claims.
As shown in fig. 1-2, a simple head rest angle adjusting device comprises a cross rod 1, the cross rod is a round rod piece, two symmetrical headrest plate mounting pieces 2 are welded on the outer peripheral surface of the round rod piece, the distance between the two headrest plate mounting pieces can be adjusted according to the needs, two sides of the cross rod are inserted with backrest mounting pieces 3, the backrest mounting pieces and the cross rod can rotate relatively, a shaft sleeve 4 is arranged between the backrest mounting pieces and the cross rod, the shaft sleeve is an oil-free engineering plastic shaft sleeve with shoulders, the cross rod and the backrest mounting pieces can be prevented from being worn mutually, the effect of reducing noise is also achieved, an electric push rod 5 is arranged between the backrest mounting pieces on the left side and the cross rod, the electric push rod is used for driving the cross rod to rotate, the backrest mounting pieces on the left side are welded to be used for hinging a hinged shaft 31 of an electric push rod shell, the left side of the cross rod is welded with two first lug plates 11 for hinging the electric push rod telescopic rods, the electric push rod is only provided with unidirectional thrust, 6 is arranged between the backrest mounting pieces on the left side, a tension spring is fixedly connected with a hanging pin 32 on the backrest mounting piece on the left side, one end of the cross rod is connected with the hanging pin, and the tension spring on the left side is connected with the hanging pin, the tension spring, the other end of the tension spring is inserted into the second lug plate on the other end, and the length of the electric push rod is shorter than the length of the electric push rod due to the fact that the electric push rod is required to be installed, and the length of the electric push rod can be reduced.
The utility model has the specific working process and principle that the electric push rod is started, the nut in the electric push rod provides thrust for the telescopic rod of the electric push rod, the telescopic rod of the electric push rod stretches out to drive the cross rod to rotate, the cross rod drives the headrest plate mounting piece to rotate to reach a required angle, when the electric push rod is reset, the nut of the electric push rod is started again to retract, the telescopic rod of the electric push rod loses the supporting force, the tension spring pulls the cross rod to reversely rotate, the telescopic rod of the electric push rod is retracted, the tension force of the tension spring is smaller, and the anti-clamping effect can be achieved. Considering how much driving force of the headrest plate is not needed, the electric push rod can be mounted on the side of the cross rod to achieve good driving effect, so that the structure can be simplified, the assembly is convenient, and meanwhile, the cost is reduced.
The utility model provides an electric push rod which is in the prior art, and the working principle can be referred to as a Chinese utility model patent with publication number of CN211481074U, namely 'push-only and pull-free electric push rod'.
