[0001] The present application relates to the technical field of household products, and in particular to an anti-slip knurled door handle. Background Art

[0002] In order to facilitate the opening and closing of the door, a handle is usually provided on the inner and outer sides of the door body. Under normal circumstances, the hand directly holds the handle and can turn the door handle through contact friction. However, for some door locks that have been used for a long time, the door handle may become difficult to turn due to lack of lubricant inside. Therefore, in the prior art, knurling is provided on the door handle to increase the contact friction. However, if a highly slippery substance, such as grease, sticks to the hand or the handle, the grease will fill the groove of the knurling, greatly reducing the friction enhancement effect of the contact with the palm. Summary of the invention

[0003] The purpose of the present application is to provide a knurled door handle with a more stable anti-slip effect.

[0004] In order to achieve the above objectives, the present application provides an anti-slip knurled door handle: comprising a gripping handle, the outer side surface of the gripping handle is fixedly connected to a plurality of friction protrusions, one end of the gripping handle is fixedly connected to a connecting handle, the connecting handle comprises an extension shaft, the end of the extension shaft is fixedly connected to a lock sleeve via a limit stop ring, and the end surface of the lock sleeve is provided with a stop groove for connecting with a lock core inside the door to achieve linkage.

[0005] As a preference, the gripping handle is a rotating body, and the cross-sectional area gradually decreases from the middle to both ends, so as to better fit the inner wall of the palm in the gripping posture.

[0006] Preferably, a friction groove is provided on the outer side of the gripping handle, and the extension direction of the friction groove is parallel to the axis of the gripping handle. There are a plurality of friction grooves, and the plurality of friction grooves are all located between the friction protrusions, so the increased friction effects of the two are independent of each other.

[0007] As a preference, the plurality of friction protrusions are divided into a plurality of groups, and the friction protrusions in each group are arranged equidistantly around the axis of the handle, so that the contact friction characteristics of various parts of the handle are improved.

[0008] As a preferred embodiment, the friction protrusions are made of silicone material, which has a high friction coefficient and good affinity with the skin.

[0009] As a preferred embodiment, the gripping handle is made of stainless steel or wood, taking into account both aesthetics and durability.

[0010] Preferably, the outer side surface of the gripping handle is provided with grooves, the number of the grooves corresponds to the number of the friction protrusions, the friction protrusions are suitable for being embedded in the grooves and fixed by curing glue, and have good stability.

[0011] Preferably, the axis of the extension shaft is perpendicular to the axis of the gripping handle, and a coaxial annular mating groove is provided on the end face of the limit ring facing the lock sleeve, which is used to cooperate with the lock body shell on the outside of the door to form a rotating pair to improve the smoothness of the handle rotation.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] (1) By providing a raised friction structure on the gripping portion of the handle, it is not easy for the slippery material on the door handle to completely cover the friction structure, so the handle is more likely to come into contact with the palm to ensure friction, thereby making the anti-slip performance of the handle more stable;

[0014] (2) The friction protrusions are fixed in the grooves formed by the knurling on the outer surface of the gripping handle, so the connection with the gripping handle is very stable. The entire handle also has an appearance similar to that of a bitter melon, which makes the handle have a certain decorative purpose. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0023] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0024] like Figure 1-4 The anti-slip knurled door handle shown includes a gripping handle 1 made of stainless steel or wood. If stainless steel is used, the gripping handle 1 has a very high structural strength and will not be broken even if subjected to a large external force. If wood is used, although the structural strength will be significantly reduced, the gripping feel will be better, especially in winter, and it will not be as cold as stainless steel.

[0025] In this embodiment, the gripping handle 1 is configured as a rotating body, and the cross-sectional area gradually decreases from the middle to the two ends, that is, the cross section of the gripping handle 1 perpendicular to the axis is the center of a circle, and the cross section parallel to the axis is an ellipse. The outer side surface of the gripping handle 1 is fixedly connected with a plurality of friction protrusions 102, and the friction protrusions 102 are made of skin-friendly silicone material, which is not only more comfortable when gripping, but also generates a greater contact friction force, which is the main part of improving the anti-slip performance of the door handle. The plurality of friction protrusions 102 are divided into a plurality of groups, each group has a plurality of protrusions, and the friction protrusions 102 in each group are around the axis of the gripping handle 1. The groups are arranged equidistantly, and the spacing between the groups is also uniform. The outer side of the gripping handle 1 is provided with grooves, which are produced by knurling. The number of the grooves corresponds to the number of the friction protrusions 102. The depth of the grooves does not need to be too deep, as long as it can play a role in pre-positioning the friction protrusions 102 for installation. The friction protrusions 102 are just embedded in the grooves and fixed by curing glue. Normally, the liquid curing glue will be directly applied to the grooves on the outer surface of the gripping handle 1, and then the friction protrusions 102 can be pressed into the grooves to adhere the friction protrusions 102, and the fixation can be completed by waiting for the liquid glue to cure.

[0026] The outer side surface of the gripping handle 1 is also provided with a friction groove 101. The friction groove 101 is in the shape of an elongated strip and is produced by cutting the outer surface of the gripping handle 1 with a rolling cutter. The extension direction of the friction groove 101 is parallel to the axis of the gripping handle 1. There are also a plurality of friction grooves 101. These friction grooves 101 are equidistantly arranged around the axis of the gripping handle 1. The plurality of friction grooves 101 are all located between the friction protrusions 102. That is to say, there is no overlapping portion between the friction groove 101 and the groove produced by the knurling on the outer side surface of the gripping handle 1.

[0027] One end of the gripping handle 1 is fixedly connected with a connecting handle 2, which is usually an integrated structure with the gripping handle 1. The connecting handle 2 is the part that connects the door handle and the door lock. The connecting handle 2 specifically includes an extension shaft 201, which allows the gripping handle 1 to be at a certain distance from the door body. The axis of the extension shaft 201 is perpendicular to the axis of the gripping handle 1, so that the gripping handle 1 can rotate along the axis of the extension shaft 201. The end of the extension shaft 201 is fixedly connected to a lock shaft sleeve 203 through a limit stop ring 202. The limit stop ring 202 is used to limit the insertion depth of the connecting handle 2 and the door lock. The end face of the limit stop ring 202 facing the lock shaft sleeve 203 is provided with a coaxial annular fitting groove 205, which is used to fit with the convex ring on the outer end face of the door lock cover to improve the stability of the relative rotation of the connecting handle 2. The end face of the lock shaft sleeve 203 is provided with a stop groove 204, which usually passes through the inner and outer walls of the lock shaft sleeve 203 and is plugged into and matched with the driving shaft of the lock core, thereby realizing the linkage between the door handle and the lock core inside the door.

[0028] Working principle: Before use, first insert the connecting handle 2 into the driving shaft of the door lock. After insertion, the holding handle 1 is restricted in the horizontal direction. The palm holding the holding handle 1 will directly contact the friction protrusion 102 made of silicone, obtaining a larger contact friction force, thereby effectively preventing the hand from slipping when opening the door.

[0029] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
