Technical field:

[0001] The utility model belongs to the technical field of luggage accessories, and particularly relates to a pull rod combination handle. Background technology:

[0002] The luggage is equipped with a telescopic handle, which provides the convenience of travel and can be hidden on the side of the luggage when not in use. The handle generally includes a handle and telescopic rods symmetrically separated at both ends of the handle. The handle is provided with a start button that can control the telescopic rod. For example: CN200420076288.2 discloses a handle for a handle, including a base, an upper cover and a button; the button is provided between the upper cover and the base, and protrudes from the reserved hole of the upper cover. The upper cover has hooks extending downward at both ends, which can be buckled on the base to form a positioning; the two ends of the horizontal rod connected to the bottom of the button can contact the top of the telescopic rod passing through the base to control the telescopic action of the rod. And CN201120114614.4 discloses a handle for a handle, which has roughly the same structure and function, except that the button and the lever are designed separately and the shape is different.

[0003] Traditional rod grips need to be reshaped according to different specifications, resulting in high processing costs, especially for small batches. How to provide a more reasonable technical solution has become the object of this invention. Summary of the invention:

[0004] The purpose of the utility model is to design a pull rod combined handle which is assembled by processing plastic parts and profiles.

[0006] A central plastic part with a button hole formed upward;

[0007] Two sections of profiles are symmetrically arranged on both sides of the central plastic part;

[0008] Two corner plastic parts are installed at the ends of the profile to fix the telescopic rod;

[0009] A button control, the main body of which is a crossbar with a button protruding upward in the middle; it is arranged in a cavity formed by the central plastic part, the profile and the corner plastic part, the button protruding in the button hole of the central plastic part, and the two ends of the crossbar abut against the top of the control rod passing through the corner plastic part to drive the control rod to move downward.

[0010] The corner plastic parts and the central plastic parts are both formed by upper and lower molds, and the upper mold is formed with screw columns and the lower mold is formed with corresponding screw holes. The two are locked and clamped by screws; the lower mold of the corner plastic part is formed with a connecting column for connecting the telescopic rod, and the center of the connecting column has a through hole for the control rod to slide through, and the upper mold of the central plastic part is formed with a button hole; the cross bar and the profile of the button control are formed with through holes corresponding to the positions of the screw columns of the upper mold, and the cross bar is provided with a short spring between at least two symmetrical bottom edges of the through holes and the inner edge of the screw hole of the lower mold, with the help of the short spring to maintain the button protruding into the button hole.

[0011] Two short springs are provided and are respectively sleeved on two screw posts passing through the button control crossbar on the split mold of the central plastic part.

[0012] A lower spring seat is formed at the lower parting center of the central plastic part, and a corresponding upper spring seat is formed at the bottom of the button control. A long spring is arranged on the upper spring seat and the lower spring seat.

[0013] The lower parting screw holes of the corner plastic part and the central plastic part are concave structures and form circular bosses inward. The depth of the concave structure is greater than the thickness of the screw head, and the through holes of the profile corresponding to the circular bosses are large-diameter holes.

[0014] The connecting column formed by the lower split mold of the corner plastic part is provided with one or two rivet holes for fixing the rod, and the control rod is provided with a long groove for avoidance at the position corresponding to the rivet hole.

[0015] The utility model has the characteristics of unique conception, simple structure and low production cost; the central plastic part and the corner plastic parts are universal molded parts, and the width specification of the pull rod handle can be adjusted by cutting the length of the profile to meet the matching of different products, reducing the deficiency of the existing technology that each specification product needs to be newly molded.

[0030] Reference Figures 1 to 3 The pull rod combination handle includes: a central plastic part 1, a profile 2, a corner plastic part 3 and a button control 4; the central plastic part 1, the corner plastic part 3 and the button control 4 are formed by plastic parts, and the profile 2 is an aluminum alloy profile. It can be cut and used according to different specifications to assemble handles of different widths, and only the corresponding molded button control 4 is required.

[0031] The central plastic part 1 and the corner plastic part 3 are both designed with upper and lower split molds, that is, the upper split mold 5 of the central plastic part and the lower split mold surface 12 of the central plastic part, as well as the upper split mold 31 of the corner plastic part and the lower split mold 32 of the corner plastic part; all upper split molds are formed with screw columns 6, and the lower split molds are formed with corresponding screw holes 61, and the two are locked by screws 62 and clamp the profile 2 at the same time; in addition, the lower split mold 32 of the corner plastic part is formed with a connecting column 33, and the center of the connecting column 33 has a through-hole 331. The connecting column 33 provides riveting connection for the telescopic rod, and the control rod 5 in the telescopic rod slides through the said through-hole 331, and the top protrudes from the through-hole 331; the button hole 111 is formed on the upper split mold 11 of the central plastic part.

[0032] The button control 4 comprises a crossbar 41 with a button 42 protruding upward from its center. It is positioned within the cavity formed by the central plastic part 1, the profile 2, and the corner plastic part 3. The button 42 protrudes from the button hole 111 in the upper mold of the central plastic part. The ends of the crossbar 41 abut against the top of the control rod 5, which passes through the connecting post, to drive the control rod 5 downward. More specifically, through-holes 63 are formed in the crossbar 41 and the profile 2 at locations corresponding to the screw posts 6 in the upper mold. Short springs 7 are installed between the bottom edges of at least two symmetrical through-holes 63 on the crossbar 41 and the inner edges of the screw holes 61 in the lower mold. These springs maintain the button 42 protruding from the button hole 13, allowing it to protrude for finger-pressing operation.

[0033] Two short springs 7 are located on the central plastic part 1 and are respectively mounted on two screw posts 6 that extend through the crossbar of the button control in the upper split mold 11 of the central plastic part. This maintains the concentrated elastic force when the button 42 is pressed downward, while the two upward-moving control rods 5 at the ends of the crossbar 41 resist the upward force. More specifically, a lower spring seat 121 is formed in the center of the lower split mold 12 of the central plastic part, and a corresponding upper spring seat 421 is formed at the bottom of the button 42 of the button control. A long spring 71 is mounted between the upper spring seat 421 and the lower spring seat 121 to further provide elastic support for the button 42.

[0034] The lower parting screw holes 61 of the corner plastic parts and the central plastic parts are concave structures and form inwardly formed circular bosses 611. The depth of the concave structure is greater than the thickness of the screw head, so the fastening screws 62 can be immersed therein while maintaining a smooth surface; the through hole 63 of the profile 2 corresponding to the circular boss 611 is a large-diameter hole to ensure that the circular boss 611 can be embedded in the through hole 63 on the lower side of the profile to stably clamp the profile.

[0035] The connecting column 33 formed by the lower mold of the corner plastic part is provided with one or two rivet holes 332 for fixing the rod. The control rod 5 is provided with a long groove 51 corresponding to the position of the rivet hole to ensure that the control rod 5 can slide freely up and down.
