Description

TECHNICAL FIELD

[0001] The utility model relates to lockset handle technical field, especially relate to a leather sheath handle rod structure. BACKGROUND

[0002] In the lockset technical field, the lockset handle is as the key component of user and lockset interaction, and its holding hand feeling directly influences the user's use experience. At present, for improving holding comfort, the industry generally adopts the technical scheme of setting the leather sheath on the handle rod surface of metal material. The scheme effectively improves the defects of metal handle rod cold and holding feeling hard through the use of the characteristics of soft and antiskid of leather material, and significantly enhances the comfort and stability when the user holds.

[0003] In the prior art, the metal handle rod needs to be surface treated and then the leather sheath is processed on the surface of the metal rod, which has the following problems: first, the sequential processing affects the processing efficiency of the handle; second, the metal handle rod after surface treatment is prone to surface scratches and contamination during multiple transportation and processing. In addition, the processing process of the leather sheath in the prior art is relatively complex, such as setting a wooden strip with sewing space on one side of the metal handle rod, and sewing the leather material after being adhered to the metal rod, which reduces the processing efficiency and is not conducive to the disassembly and replacement of the handle leather sheath. UTILITY MODEL CONTENTS

[0004] The utility model aims at the defects and deficiencies of the prior art, and provides a leather sheath handle rod structure.

[0005] To achieve the above-mentioned purpose, the utility model adopts the technical scheme that:

[0006] The leather sheath handle rod structure comprises a handle rod, a plastic sleeve and leather, the leather is sewn and fixed outside the plastic sleeve, the plastic sleeve is provided with an insertion hole matched with the handle rod, and the handle rod is tightly inserted into the insertion hole.

[0007] Further, adjacent two edges of the surface of the plastic sleeve are provided with a through hole group, the through hole group is composed of multiple through holes, and the leather is in the shape of "U".

[0008] Further, the end face of the insertion hole and the inner side wall of the insertion hole are provided with a chamfered surface.

[0009] Further, multiple exhaust grooves are arranged on the inner side wall of the insertion hole, and the exhaust grooves extend from the end face of the insertion hole to the bottom end of the insertion hole.

[0010] Further, the insertion hole, the exhaust grooves and the plastic sleeve are integrally injection molded.

[0011] With the above structure, the beneficial effects of this utility model are as follows: the handle and the leather sleeve are processed simultaneously, and the leather is fixed to the plastic sleeve by sewing, so that the plastic sleeve and the leather form an integral structure; then the processed metal rod is inserted into the leather sleeve to complete the processing of the leather sleeve handle. This structure not only improves the processing efficiency of the leather sleeve handle, but also improves the maintenance and replacement flexibility of the handle leather sleeve due to its detachable design.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figs. 1 to 3 As shown, the present invention provides a leather handle structure, comprising a handle 1, a plastic sleeve 2, and leather 3; the leather 3 is sewn and fixed to the outside of the plastic sleeve 2; the plastic sleeve 2 is provided with an insertion hole 202 that matches the handle 1; the handle 1 is tightly inserted into the insertion hole 202.

[0020] The plastic sleeve 2 is integrally injection molded, which is easy to mold and process.

[0021] The surface of the handle 1 is frosted to increase the friction between the handle 1 and the inner wall of the insertion hole 202, making it less likely for the plastic sleeve 2 to come loose from the handle 1. The leather 3 is fixed to the plastic sleeve 2 by sewing, so that the plastic sleeve 2 and the leather 3 form an integral structure. In this structure, the leather 3 and the handle 1 are connected as one unit through the plastic sleeve 2 as an intermediary. The plastic sleeve 2 is difficult to deform, so that the leather 3 is more firmly connected to the handle 1, improving the service life of the handle.

[0022] As a preferred mode of the utility model, the two adjacent edges of the surface of the plastic sleeve 2 are provided with a through hole group; the through hole group is composed of a plurality of through holes 201; the leather 3 is in a U shape; the through holes are used for sewing thread; when the plastic sleeve 2 is connected with the leather 3, the leather 3 is folded into a U shape first, and then the two ends of the leather 3 are shielded on the front and rear end faces of the through hole 201 respectively; then the sewing thread is used to pass through each through hole 201 in sequence to sew and fix the leather 3 on the plastic sleeve 2. After the leather 3 is sewn and fixed on the plastic sleeve 2, the leather 3 has a wrapping force on the plastic sleeve 2, so that the plastic sleeve 2 is not easy to crack after being stressed, and the service life of the handle is further improved.

[0023] As a preferred mode of the utility model, the end face of the insertion hole 202 and the inner side wall of the insertion hole 202 are provided with a chamfer surface 20201; the chamfer surface 20201 facilitates the handle rod 1 to be guided into the plastic sleeve 2.

[0024] As a preferred mode of the utility model, a plurality of exhaust grooves 203 are arranged on the inner side wall of the insertion hole 202; the exhaust grooves 203 extend from the end face of the insertion hole 202 to the bottom end of the insertion hole 202; since the handle rod 1 and the insertion hole 202 of the plastic sleeve 2 are in interference fit, there is no gap between the insertion hole 202 and the handle rod 1, when the handle rod 1 is inserted into the insertion hole 202, the original air in the insertion hole 202 is compressed, and the air is discharged through the exhaust grooves 203, so that the handle rod 1 can be smoothly inserted into the insertion hole 202, and the assembly difficulty of the handle rod 1 and the plastic sleeve 2 is reduced.

[0025] As a preferred mode of the utility model, the insertion hole 202, the exhaust groove 203 and the plastic sleeve 2 are integrally injection molded.

[0026] The above is only a preferred embodiment of the utility model, so equivalent changes or modifications made according to the structure, features and principles of the utility model patent application range are included in the utility model patent application range.
