Description

Combination device of handlebar and standpipe

The utility model relates to a combination device of a handle and a vertical pipe.

Generally, products with a large volume are not only inconvenient to carry but also take up space when stored, mainly because a large number of retractable and removable structural designs are used in order to achieve the effect of reducing the volume. Common telescopic and detachable structures of this type are mostly arranged on pipe rod members that need to be adjusted in length, such as general folding or bicycles and scooters, that is, the telescopic and detachable structures are mostly used on the longer and higher frame of the frame for use. It can be shortened or detachable for easy storage or carrying. As far as the structure of the handle and standpipe at the front of the frame is concerned, it is a long pipe member, so it can be used in the form of a telescopic pipe. The design is shortened, and the telescopic tube is designed to achieve a fixing and dismounting function.

Commonly used tube bundle components with quick-release wrench are shown in Figures 5 and 6. The end of the outer tube A of the telescopic tube body is axially provided with a split groove A1, and a tube bundle C with a quick-release wrench C1 is attached, and the A convex line C2 protruding inside the tube relative to the groove A1 is formed on the inner surface of the ring of the tube bundle C, while the inner tube B forms a V-shaped concave groove on the outer tube surface corresponding to the convex line C2 on the inner surface of the tube bundle C. There is a longitudinal groove B1, and an abutment column B2 is protruded from the groove B1; thus, the inner tube B can slide and expand along the convex line C2 on the inner surface of the tube bundle C by means of the groove B1, and abut against it so that it cannot be turned, and at the same time, the abutment column B2 forms a blocking function against the convex line C2 on the inner surface of the tube bundle C. However, the above-mentioned detachable telescopic tube body has a large number of overall matching components and complex shapes, and it is time-consuming to manufacture and assemble. If it is used for a simple car model or a car model with a special shape that is simple and wants to reduce manufacturing costs, it cannot achieve the best effect. Effect.

The purpose of the utility model is to provide a combination device of a handle and a standpipe that can be quickly aligned and fixed, and can be quickly assembled and disassembled.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a combination device of a handle and a vertical pipe, the upper pipe section of the vertical pipe is provided with radially corresponding through fixing holes, and the lower section of the vertical pipe of the handle is passed through It is placed inside the upper pipe section of the vertical pipe, and a spring snap element is arranged inside the pipe section where the vertical pipe penetrates into the vertical pipe. The upper tube wall of the upper tube is punched and formed with a longitudinal convex body that is concave to convex, and the vertical tube that penetrates the handle inside the vertical tube is also correspondingly punched to form a longitudinal groove.

After adopting the above structure, the positioning of the handle relative to the standpipe assembly described in the utility model can use the concave groove of the vertical pipe of the handle to fit the convex body of the standpipe, so that the convex pin in the vertical pipe can be moved to the standpipe When the fixing hole is formed, the automatic alignment is formed and the card is fixed. If the force is applied to the convex pin, it can be retracted and separated from the fixing hole, and then the handle can be pulled away to achieve the overall automatic alignment and locking. Its disassembly and assembly are fast and easy. Easy, with a certain convenience.

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.

Fig. 4 is the combined sectional view of another embodiment of the utility model;

Fig. 5 is the structural representation of conventional article;

Fig. 6 is a combined sectional view of a conventional product.

First of all, as shown in Figure 1, the combination device of the handle and the standpipe described in the utility model mainly adopts the way of the standpipe 1 and the handle 2 being clamped in sections to be freely disassembled and assembled; its structural features are designed as :

The upper pipe section of the standpipe 1 is provided with radially corresponding through fixing holes 11, the lower section of the vertical pipe 21 of the handle 2 is placed inside the upper pipe section of the standpipe 1, and the vertical pipe 21 penetrates into the pipe section of the standpipe 1 A snap element 3 with a protruding pin 31 is arranged inside, so that the protruding pin 31 protrudes through the preset perforation 211 of the vertical tube 21, and the upper tube wall of the vertical tube 1 is stamped to form a longitudinal protruding line from concave to convex. body 12, and the vertical pipe 21 of the handle 2 penetrating into the inside of the standpipe 1 also forms a longitudinal groove 212 corresponding to the stroke.

Due to the above structural design, as shown in Figures 2 and 3, the concave groove 212 of the lower section of the vertical pipe 21 of the handle 2 can be aligned with the convex body 12 of the vertical pipe 1 and inserted into the upper pipe section of the vertical pipe 1, This alignment form can make the convex pin 31 of the vertical tube 21 of the handle 2 inside the snap element 3 correspond to the fixing hole 11 of the vertical tube 1 to be in a straight line, and then push the vertical tube 21 to make the convex pin of the snap element 3 inside. The pin 31 is correspondingly moved to the fixing hole 11 of the standpipe 1, and then the protruding pin 31 can be automatically snapped into the fixing hole 11 to be fixed against each other. The positioning of the handle 2 relative to the standpipe 1 in this way is to use the convex pin 31 to engage the fixing hole 11 for assembly positioning, which is fast, simple and easy to operate; in addition, in the above-mentioned embodiment, only a single fixing hole 11 is used As an illustration of the connected mode, if two or more fixing holes 11 are used in the upper pipe section of the vertical pipe 1, and the lower section of the vertical pipe 21 of the handle 2 is appropriately lengthened, the convex pin in the vertical pipe 21 will 31 can arbitrarily choose several fixing holes 11 that are longitudinally arranged relative to the standpipe 1 to be stuck, so as to achieve the effect of stretching and adjusting its overall connection length.

In addition, when you want to detach the handle 2, you only need to apply force to the protruding pin 31 to make it shrink away from the fixing hole 11 of the standpipe 1, then the handle 2 can be detached, and the operation is fast and convenient.

Also, one side of the standpipe 1 in the above-mentioned embodiment is stamped to form a longitudinal convex body 12, and one side of the vertical pipe 21 of the handle 2 is also correspondingly punched with a vertical groove 212, but it can also be as shown in the figure As shown in 4, two forms are arranged on the symmetrical sides of the convex body 12 and the concave groove 212.
