Description

Case handle Technical Field The invention relates to the technical field of luggage parts, in particular to a luggage handle. Background The handle of the case usually bears a relatively large tensile strength, so that the handle of the case is made of rigid materials in design, and the structure is similar to a weighing handle and the case of a patent CN201810829218.6, which are applied to the case, and the rigid connecting pieces are connected in a hinged manner. There are also some luggage handles made of materials such as rubber and resin for the purpose of pursuing hand feeling, but the materials are soft and hand-protecting, and can be made into a "telescopic handle", such as patent CN 201920642683.9-a telescopic luggage handle, although the tensile strength is poor. The telescopic handle finger in the prior art is provided with a connecting part between the handle main body and the fixing parts at two ends, when the handle main body is lifted, the connecting part allows the handle main body to be properly prolonged, and when the handle main body is put down, the connecting part is reset, so that the handle main body returns to the original length or position. The most common practice is to arrange two elongated grooves at two ends of the rubber handle body, wherein the two grooves are respectively fixed with the fixing pieces at two ends, so that the rubber handle body has a certain movable stroke. The disadvantage of this construction is that the retraction is entirely dependent on the elasticity of the rubber, although the rubber ages during use, the retraction effect is poor and even cannot be retracted. The handle made of rubber, resin and other materials is soft and handguard, but the materials are easy to age and deform, have poor bearing capacity, are not reasonable in structural design and are easy to damage. In addition, some manufacturers only adopt the design of torsion springs at the joints of the handles in order to reduce the cost, so that the handles can be reset, but the handles are fast in speed, impact sound of 'snap' is brought, the use feeling is affected, and impact marks can exist at the impact positions for a long time. Disclosure of Invention The present invention aims to overcome at least one of the above-mentioned drawbacks of the prior art and to provide a luggage handle for realizing elastic telescoping of the handle to increase the service life of the handle. The luggage handle comprises a handle part and a connecting part, wherein the connecting part is embedded at two ends of the handle part, the connecting part comprises a fixed shell, a pull rod, a spring group and a base assembly, the pull rod, the spring group and the base assembly are arranged in the fixed shell, one end of the pull rod is connected with the handle part, the other end of the pull rod is connected with the base assembly, the upper end of the spring group is fixed on the inner wall of the fixed shell, the lower end of the spring group is detachably arranged on the base assembly, and the pull rod is driven to move upwards by pulling the handle part upwards, so that the spring group is compressed from bottom to top to realize elastic stretching. Further, the suitcase handle of the invention also comprises a bearing, and the pull rod is sleeved in the bearing. The bearing is cylindrical, the center shaft is provided with a through hole which penetrates through, the outer layer of the pull rod is integrally sleeved with the bearing, the bearing keeps the pull rod to be directly upwards and downwards in the stretching process, and the stretching stability is improved. In order to improve the service life, the pull rod is a stainless steel pull rod. When the handle portion is pulled up, the stainless steel pull rod rises along with the handle portion, the base assembly upwards compresses the spring set, and the design of the spring set can keep pressure balance, and the inner limiting structure of the fixed shell provides stable and reliable strength support for the suitcase. When the handle part is put down, the stainless steel pull rod stably sinks under the action of the resilience force of the spring group, and drives the handle part to reset until the handle part contacts the upper limit position of the fixed shell. The luggage handle also comprises a damping component, wherein interfaces for connecting with the damping component are arranged on two sides of the lower end of the fixed shell. In practical application, in order to reduce the cost, only a torsion spring is adopted at the joint of the handle and the box body, so that the handle can be reset, but the speed is very high, the impact sound of 'snap' is brought, and the use feeling is influenced. According to the invention, the damping component is added at one of the connecting points, so that the strong torsion of the torsion spring is neutralized, and the whole handle can be slowly reset. Further, the spring group is four groups of pressure
