Abstract
The utility model belongs to chair technology field, is used for landing.It discloses a kind of Simple backrest chair for facilitating installation, including chair leg, seat plate and backrest, several chair legs are installed in the side of seat plate；Be provided between backrest and chair leg projected on longitudinal section it is trapezoidal help elbow, helping elbow includes two support arms being parallel to each other, and one is long and the other is short for two support arms.The utility model structure simply while having both stability, also helps elbow can replace and realizes handrail function；Trapezoidal to help toggle structure simple, moulding process is simple, has both mechanical property, is suitable for mass production.
Description
Technical field
The utility model belongs to the technical field of the seat, in particular to a kind of chair.
Background technique
Chair generally includes backrest, seat board, handrail and chair leg, and the bottom of usual handrail and seat board are fixed or and chair
Leg is integrally formed, and the side of backrest and handrail is fixed.
But the traditional Chinese chair of above structure is not suitable for mass production.It is, therefore, desirable to provide a solution comes side
Just the batch production of chair.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of Simple backrest chairs for facilitating installation, have both facilitated batch raw
It produces, and facilitates installation.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
A kind of Simple backrest chair facilitating installation, including chair leg, seat plate and backrest, several legs are installed in described
The side of seat plate；It is provided between the backrest and leg and projects trapezoidal elbow of helping on longitudinal section, it is described to help elbow
Including two support arms being parallel to each other, one is long and the other is short for two support arms.
Further, the coefficient of elasticity of the longer support arm is less than the coefficient of elasticity of the shorter support arm.
Further, the longer support arm is molded by PP material, the shorter support arm by PP material and
TPU material composition.
Further, the both ends of the shorter support arm are the rigid attachment arm made of PP material, and centre is by TPU
Resilient attachment arms made of material；The profile of the resilient attachment arms is in bow font or S-shaped.
Further, one end of the rigid attachment arm is provided with countersunk head slot, the both ends setting of the resilient attachment arms
There is the counter sink matched with countersunk head slot.
A kind of Simple backrest chair facilitating installation provided by the utility model, structure is simple, only include chair leg, seat plate and
Backrest, and the coupling part between chair leg and backrest yet forms and helps elbow, and human body ancon is facilitated to be hooked with elbow is helped.
Compared with prior art, the utility model has the following beneficial effects:
One, structure is simple and has both the had comfortable function of conventional chair, in substitution tradition Simple seat preceding chair leg with lean on
Fixed form between back also helps elbow can replace and realizes handrail function while having both stability.
Two, trapezoidal to help toggle structure simple, moulding process is simple, has both mechanical property, is suitable for mass production.
Three, the structure of support arm is provided with impact resistance according to the case where backrest stress, and pressure-resistant buffer structure, chair is more
It is durable, longer life expectancy.
Detailed description of the invention
Fig. 1 is the left view of the utility model embodiment；
Fig. 2 is the explosive view for helping elbow of the utility model embodiment；
In figure: chair leg before 1- seat plate, 21-, 22- back leg, 3- backrest, the first support arm of 31-, the second support arm of 32-,
321- rigid attachment arm, 322- resilient attachment arms, 323- counter sink.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
Embodiment:
As shown in Figure 1, a kind of Simple backrest chair for facilitating installation provided by the utility model, including chair leg, 1 and of seat plate
Backrest 3, wherein chair leg includes preceding chair leg 21 and back leg 22, and forward and backward chair leg is mutually fixed in splayed and the side of seat plate 1；
It is provided with to project on longitudinal section between backrest 3 and back leg 22 and trapezoidal helps elbow.Helping elbow includes two branch being parallel to each other
Brace, respectively the first support arm 31 and the second support arm 32, the length of the first support arm 31 are greater than the length of the second support arm 32
Degree.
For first support arm 31 in the top of the second support arm 32, the second support arm 32 will receive biggish torque conduction, because
This, if the second support arm 32 is rigid words, the junction of the first support arm 31 and backrest 3 is possible to directly to roll over
It is disconnected.In consideration of it, coefficient of elasticity of the coefficient of elasticity of the first support arm 31 less than the second support arm 32.
Preferably, the first support arm is molded by PP material, and the second support arm is made of PP material and TPU material.TPU
It include the biggish component of a variety of coefficient of elasticity in material, such as nylon, rubber, coefficient of elasticity are greater than PP material.So
The average spring rate of two support arms is greater than the coefficient of elasticity of the first support arm.
As shown in Fig. 2, the both ends of the second support arm are the rigid attachment arm 321 made of PP material, centre is by TPU material
Resilient attachment arms 322 made of expecting；The profile of resilient attachment arms 322 is in bow font or S-shaped.In this way, the power of resilient attachment arms 322
It is more obvious to learn performance, when torque is transferred to resilient attachment arms 322, faint elastic deformation occurs for resilient attachment arms 322, and first
Support arm 31 is unlikely to fracture.Improve the service life of chair.
Specifically, one end of rigid attachment arm 321 is provided with countersunk head slot, the both ends of resilient attachment arms 322 be provided with
The counter sink 323 that countersunk head slot matches.Counter sink 323 extends from the both ends of resilient attachment arms 322 along its length direction
Come, counter sink 323 is inserted into countersunk head slot and is hidden, makes itself and rigid attachment arm 321 perfect registration, one support arm, conducive to holding
Connect the external force torque being transmitted to.Counter sink 323 is locked with screw, but can perfect hidden screw, both facilitate user group
Dress helps elbow, and can take into account design, beautiful and generous.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
