Description

Double axis head

The present invention provides a positioning structure for a rod, particularly a double-axis clamp.

In mechanical design, if two parallel rods are to be positioned relative to each other, the tube bundle is usually used to clamp the parallel connecting rods. For example, the conventional tube bundle cross-sectional view shown in the first figure mainly uses a metal sheet 10 to wrap around the outer edges of two parallel rods 20 to form two shaft holes 11 for accommodating the rods 20. The metal sheet 10 has an internal compression slit 12 between the two shaft holes 11. A compression assembly 13 can be used to penetrate and lock in the center of the metal sheet 10. By applying pressure to the internal compression slit 12, the shaft hole 11 can be tightened to clamp the rod 20.

The disadvantage of this implementation is that during the positioning process, the center of the metal sheet 10 is exactly where the compression assembly 13 is set and deformed, and the deformation will cause a pulling force to be generated between the two shaft holes 11. If the two ends of the two rods 20 are also connected to other mechanisms, it may cause the rods 20 to bend. If the rods 20 have a load requirement, the compression assembly 13 must be locked tighter. At this time, the deformation of the metal sheet 10 and the bending of the rods 20 will be more obvious. Therefore, this structure is not suitable for use in rods 20 with linear displacement requirements and load requirements.

In addition, if a connection structure with external objects is to be set on the metal sheet 10, the section with the internal compression seam 12 must be avoided, otherwise the internal compression seam 12 will not be easily deformed and lose its function, or the objects fixed outside the metal sheet 10 will be deformed or damaged; furthermore, if the connection structure is set in the center of the metal sheet 10, it will hinder the setting and assembly of the compression assembly 13. Therefore, the implementation of the known metal sheet 10 is only suitable for providing mutual positioning between the two rods 20, and is not suitable for connecting with external objects.

The main purpose of the present invention is to provide a double-axle tie head for setting up two parallel rods and suitable for being connected to various objects. To achieve the above purpose, the present invention provides a double-axle tie head, which includes a body, the body is provided with two axle holes, the two axle holes penetrate the body and are parallel to each other, and the body has at least one reserved connection part for connecting to external objects. The double-axle tie head can be pre-connected to external objects (such as the rear handrail of a motorcycle), and then provide two parallel rods for passing through.

In one embodiment, a sleeve portion is axially extended from the main body corresponding to at least one of the two axle holes. When the sleeve portion is subjected to external pressure, it will be contracted inwards. Thus, the double-axle tie head can be pre-connected to an external object (such as a motorcycle rear handrail) and then two parallel rods are provided for penetration. In practice, if a corresponding sleeve portion is only provided for a single axle hole, a tightening device can be provided on the sleeve portion. By means of a fitting, a pressure is provided to the sleeve part to tighten the rod that is about to pass through. At this time, if the two parallel rods are fixed to each other through other mechanisms other than the double-axis clamp head, tightening a single rod can simultaneously fix the two parallel rods; if corresponding sleeve parts are provided for both shaft holes, tightening parts can be provided on the two sleeve parts to tighten the two parallel rods at the same time.

In one embodiment, at least one reserved connection portion has a connection groove, which can be used to accommodate and connect tubular or rod-shaped objects, such as a motorcycle rear handrail, and can be welded and fixed to the motorcycle rear handrail.

In one embodiment, at least one reserved anchor portion is penetrated by a plurality of anchor holes, so that the reserved anchor portion can be fastened to an object having a corresponding hole position by a bolt.

In one embodiment, a reserved anchoring portion is provided with an anchoring plane at a position corresponding to the penetration position of the plurality of anchoring holes, and in conjunction with the arrangement of the plurality of anchoring holes, the reserved anchoring portion can be directly locked with bolts on an object having a bearing surface corresponding to the anchoring plane.

In one embodiment, a docking groove is provided in the above-mentioned docking plane, and the docking groove divides the docking plane into two. It can be used to lock a clip together with the above-mentioned multiple docking holes, and the clip can be clamped on the rear armrest of the motorcycle.

In one embodiment, the main body is provided with at least one material reducing groove to reduce the weight of the double-axis bundle head.

In one embodiment, the body is made of metal material to provide the dual-axis clamp with better structural strength.

In one embodiment, the main body is a one-piece casting to provide the double-axis bundle head with a sturdy and durable use effect.

In one embodiment, the sleeve portion is provided with at least one cut groove, so that the sleeve portion can produce a good tightening effect.

In one embodiment, a dilated hole is provided at the closed end of the cut groove, and the setting of the dilated hole can make the convergence effect more obvious.

In one embodiment, the two shaft holes are arranged horizontally, and the sleeve portion is provided with two grooves, which vertically divide the sleeve portion into two halves, so as to facilitate the processing of the grooves.

In one embodiment, the two shaft holes are arranged horizontally, and the sleeve portion is provided with two grooves, which horizontally divide the sleeve portion in half, so that the sleeve portion has the function of extending the bearing capacity of the shaft holes to enhance the bearing effect provided to the rod body.

Please refer to the second to fourth figures, the double-axis tie head shown in the first embodiment of the present invention includes a body 30, which has two axial holes 31, two tie sleeves 32 and a reserved joint 33 and other main structures.

The two axial holes 31 are arranged horizontally, and the two axial holes 31 are parallel to each other and penetrate the body 30. The two collar portions 32 are arranged at the axial extension position of each axial hole 31. The collar portions 32 of this embodiment are tubular, and their diameter is the same as the diameter of the axial hole 31.

Each sleeve portion 32 is provided with two cutout grooves 321, which cut the sleeve portion 32 in half vertically or horizontally. This embodiment is described by vertical cutout. The closed end of each cutout groove 321 is provided with an expansion hole 322, so that the sleeve portion 32 has good compressibility. When the sleeve portion 32 is subjected to external pressure, it will be contracted relative to the axial direction of the axial hole 321.

The reserved connecting portion 33 is used to connect external objects. In this embodiment, the reserved connecting portion 33 has a connecting groove 331, a plurality of connecting holes 332 and a connecting plane 333, so that the user can choose the most suitable way to connect. The figure shows that the connecting groove 331 of this embodiment is perpendicular to the two shaft holes 31, and the connecting groove 331 and the shaft hole 31 are located at different levels and do not interfere with each other.

The connecting groove 331 is arranged at the bottom of the reserved connecting part 33, and can be used to accommodate and connect tubular or rod-shaped objects. The plurality of connecting holes 332 penetrate the reserved connecting part 33 for the purpose of bolt insertion. The connecting plane 333 is located at the penetration position of the reserved connecting part 33 corresponding to the plurality of connecting holes 332. The connecting groove 331 divides the connecting plane 333 into two.

The setting of the connecting groove 331 has two purposes, one of which is to directly weld the items contained therein; the other way of using it is to use bolts to pass through the multiple connecting holes 332 and then lock a clip, and then use the clip to clamp the external items in the connecting groove 331. Of course, the connecting portion 33 can also be directly locked to the external items by passing the bolts through the multiple connecting holes 332, for example, directly locked to an item with a bearing surface that can correspond to the connecting plane 333.

During implementation, the location, quantity or shape of the aforementioned connecting groove 331, connecting hole 332 and connecting plane 333 can be changed according to the use requirements; and the reserved connecting portion 33 can also be implemented by only setting the connecting groove 331 without setting multiple connecting holes 332 and an connecting plane 333, or only setting multiple connecting holes 332 and an connecting plane 333 without setting the connecting groove 331.

Please refer to the third and fifth figures, the body 30 of the double-axis tie head can be integrally cast from metal material, providing better structural strength and durable use effect. At least one material reduction groove 34 can be set at an appropriate position of the body 30 while taking into account the structural strength to reduce the implementation weight of the double-axis tie head.

Please refer to FIG6 and FIG7. When using a double-axis tie head, two parallel shafts 40 can be inserted into two shaft holes 31, and a tightening member 50 is respectively provided on the two sleeves 32 to provide a compressive force to the sleeves 32 through the tightening member 50 to tighten the two parallel shafts 40. As shown in FIG. 7, when the double-axle tie head is connected to the motorcycle rear handrail 60 by welding, locking or clamping through the reserved connection part 33, two parallel axles 40 can be provided for passing through, and the two parallel axles 40 can be adjusted in front and back positions in conjunction with the setting of the tightening member 50. The tightening member 50 of this embodiment has a quick release structure, which can be tightened or released quickly, so that the user can adjust the position of the two parallel axles 40 in the simplest and fastest way, and the two parallel axles 40 can further provide related items for mounting, for example, can be used to mount the luggage box support plate 70.

FIG8 is a vertical sectional view of the second embodiment of the present invention. This embodiment is different from the first embodiment in that an internal thread section 332a is provided in the connecting hole 332. The internal thread section 332a does not hinder the normal use of the original connecting hole 332. The purpose of its setting is to provide other items for screwing, so that the connecting hole 332 can be used more widely, or directly lock external items.

The above is only an example to illustrate the preferred implementation of the present invention, and is not intended to limit the scope of implementation. All simple substitutions and equivalent changes made according to the scope of the patent application of the present invention and the content of the patent specification are within the scope of the patent application of the present invention.
