Abstract
The utility model relates to a short part with a pull rod for an automatic umbrella frame, which comprises a short stick provided with a joint. The utility model is characterized in that a joint with an integral structure and a flexible pull rod is arranged next to the other end of the short stick. The utility model utilizes the deformability of the flexible pull rod to substitute an assembling and hinging structure between the existing pull rod and short stick so as to simplify the structures of the pull rod and the joint of the end of the short stick and reduce the assembling procedure. The utility model with the structure can be completely made of plastic materials through one-step instegral processing, and overcomes a problem that an umbrella is completely made of plastics. The utility model has the advantages of scientific design and artful and reasonable structure, and the smooth structural surface of the utility model is not easy to deform and damage as well as can not clamp or hook cloth of an umbrella cover.
Description
The utility model relates to the umbrella parts, especially a kind of improvement that is used for the Tiebar structure of automatic umbrella support frame.
En-toutcas is a necessary tool in people's daily life.En-toutcas is made up of umbrella frame frame, umbrella bar and umbrella cover usually, and the umbrella frame frame is installed on the umbrella bar by the following nest and the last nest at its center.Automatically the expansion en-toutcas forms by common en-toutcas structure being improved the design back, and its use is convenient easily.Automatically the basic structure of expansion en-toutcas is identical with common umbrella, its automatic developing machine structure is realized in the following manner: increase nest under the umbrella frame frame between nest and the last nest, the equal activity of middle nest of following nest and increase is set on the umbrella bar, be nested with a spring on the umbrella bar between middle nest and following nest, umbrella frame frame short bone middle part increase by one is used for installing the connector (butterfly) of pull bar, one end of this pull bar is fixedly hinged on short bone by connector (middle butterfly), and the other end of pull bar is hinged on down on the nest.Under the rounding state, the middle nest of umbrella frame frame slides to the handle end of umbrella bar with following nest and is lockable under the tractive of pull bar, and the spring that be nested with this moment on umbrella bar between middle nest and following nest is the compression shape; On umbrella bar between middle nest and following nest, be the spring that compress shape and save up strength and open when removing the snap close of nest down, being nested with, impel middle nest and following nest to slide to the top of umbrella bar, cause the umbrella expansion.Existing automatic expansion en-toutcas structure is comparatively complicated, especially the assembling (see figure 4) between connector that increases on the quarter butt (middle butterfly) and the pull bar, described connector is generally metal material and makes, its structure is complicated, processing and assembling all need specific purpose tool, and easy deformation is damaged, and service life is short.In actual use, people find that also the connector of this structure clamps or the hook umbrella cloth easily, thereby cause the inconvenience in the use.
The purpose of this utility model is the deficiency that exists at above-mentioned automatic expansion en-toutcas, and a kind of automatic umbrella frame frame band pull bar short bone spare that can overcome above-mentioned defective is provided.
The automatic umbrella frame frame of the utility model band pull bar short bone spare, comprise: the short bone that is provided with joint, it is characterised in that: the nearly position, termination in addition of short bone is provided with the joint of the band flexible draw bar of overall structure, and this joint and flexible draw bar end are equipped with for cooperating the shuttling holes of installing with middle nest and following nest.
The feature of the automatic umbrella frame frame of the utility model band pull bar short bone spare can also be: adopt the inlay card mode to be connected between flexible draw bar and joint, promptly the connecting portion at joint and flexible draw bar is provided with the male and female button that can embed mutually.
The design principle of the automatic umbrella frame frame of the utility model band pull bar short bone spare is: utilize the deformability of flexible draw bar, assembling is hinged structure between alternative existing pull bar and short bone.Existing plastic material can satisfy the thousands of inferior bendings of flexible draw bar fully, so can simplify the structure of pull bar and short bone end connector greatly, also greatly facilitates assembling.This structure band pull bar short bone spare can adopt the plastic material disposable integral to be processed into fully, for the inhibition and generation of moulding fully of parachute kit has overcome an another difficult problem.
The automatic umbrella frame frame of the utility model band pull bar short bone spare design science, structure is ingenious, reasonable, and result of use is good, and the body structure surface of band pull bar short bone spare whole smooth smoothness neither easy deformation damages, and also can not clamp or the hook umbrella cloth.
Automatically the concrete structure of umbrella frame frame band pull bar short bone spare is provided in detail by the following drawings and embodiment.
Fig. 1 is the structural representation of automatic umbrella frame frame band pull bar short bone spare;
Fig. 2 is another structural representation of automatic umbrella frame frame band pull bar short bone spare;
Fig. 3 is automatic umbrella frame frame band pull bar short bone spare user mode schematic diagram;
Fig. 4 is existing automatic rim structure of umbrella schematic diagram.
Embodiment 1: can be clear that from Fig. 1, this is a kind of integrally-built automatic umbrella frame frame band pull bar short bone spare, it comprises: the short bone 2 that is provided with joint 1, short bone 2 nearly other end head positions are provided with the joint 4 of the band flexible draw bar 3 of overall structure, and this joint 4 and flexible draw bar 3 ends are equipped with for cooperating the shuttling holes 5,6 of installing with middle nest and following nest.Can know from Fig. 3 and to see the application of this band pull bar short bone spare on automatic umbrella frame frame, this flexible draw bar 3 can satisfy the requirement of automatic umbrella frame frame folding exhibition fully.Joint 4 and flexible draw bar 3 ends are identical with common automatic umbrella with installation method between middle nest and the following nest.
Embodiment 2: can be clear that from Fig. 2 this is a kind of for dividing the automatic umbrella frame frame band pull bar short bone spare of body structure, flexible draw bar 3 adopts the inlay card mode to be connected with 4 of joints, promptly on joint 4, be provided with a box groove 7, the link of flexible draw bar 3 is provided with a pin thread plush copper 8 that can embed joint 4 box grooves 7, the pin thread plush copper 8 that embeds box groove 7 can not get loose under no external force effect, and joint 4 and flexible draw bar 3 ends are equipped with for cooperating the shuttling holes 5,6 of installing with middle nest and following nest.
