Description

Technical Field

[0001] The utility model relates to the field of daily necessities, in particular to a pull rod handle Background Art

[0002] In a trolley case or trolley bag and other daily necessities with a trolley, a handle is an indispensable accessory. The inventor has disclosed a handle with an expansion function in the Chinese utility model patent specification CN219556563U. The handle is provided with a screw hole or a screw column on its body. The handle provided with a screw hole or a screw column can be installed with a pan head or a mobile phone holder. The handle utilizes the structural characteristics of the trolley case or trolley bag to set a mounting mechanism on the handle, so as to expand the function of a tripod or a telescopic rod on an ordinary trolley bag or trolley case. However, users have repeatedly reported in actual use that the fixing effect of the product is not ideal when a heavier device is installed on the pan head. The specific disadvantage is that when the pan head with a heavier device is fixed on it, due to the simple use of threaded fixing, when the fixed object is heavy, a slight rotation or tilt will cause the screw connection mechanism to rotate in the opposite direction, thereby causing the fixed object to loosen. Since the pan head or other fixed equipment is directly connected to the screw hole or stud on the handle for rotation, this connection method is not conducive to stable installation. In actual application, it is easy to loosen. Utility Model Content

[0003] In view of the above problems, the purpose of the invention of the utility model is to provide a handle that can connect and fix the installation object more firmly and reliably.

[0004] In order to achieve the object, the technical solution of the utility model is to provide a handle with a locking device on the connection structure. A nut installation groove or a screw hole is provided on the body of the handle, and the nut installation groove or the screw hole can be screwed into the nut or the screw. The nut installation groove is arranged below the screw hole on the handle. When the device to be connected to the handle, such as a pan head or a mobile phone holder, is completely screwed into the screw hole on the handle, the nut placed in the nut installation groove can be screwed into the screw of the pan head or the mobile phone holder by rotation. In this way, the mobile phone holder or the pan head is not only installed on the handle through the screw hole on the handle, but also locked by the nut in the nut installation groove on the handle.

[0005] Preferably, the nut is a hand-tightened nut.

[0006] Preferably, the mounting hole is a through slot.

[0007] Optionally, the nut mounting groove provided on the handle can also be replaced by a screw hole, and the screw hole can be screwed into a set screw. The head of the set screw can be against the screw of the pan head or mobile phone holder that has been screwed into the screw hole of the handle to prevent it from loosening.

[0008] Preferably, the set screw is a hand-tightened set screw.

[0009] Preferably, the set screw is a rubber head set screw.

[0010] By improving the original handle structure, the utility model can solve the problem that the items installed on the pull rod handle are easy to loosen and fall off when the related products in the prior art are used. In addition, the device has the characteristics of simple structure, low cost and easy promotion and implementation. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] As attached Figure 1 To Attachment Figure 3As shown, the utility model mainly includes a handle body 1 and a mounting screw hole 2 and a nut mounting groove 3 provided on the handle body 1. The handle body 1 can be connected to the pull rod of the bag through the connecting rod 5 thereon. The nut mounting groove 3 can be loaded with a nut 4, and the nut 4 is provided with a second screw hole 8 thereon, and the size of the second screw hole 8 is the same as that of the mounting screw hole 2. The mounting screw hole 2 can be used for the first screw 7 on the mobile phone holder 6 to be screwed into it. When the mobile phone holder 6 is screwed into the mounting screw hole 2 on the handle body 1 through the first screw 7 thereon, the nut 4 located in the nut mounting groove 3 can be screwed so that the nut 4 is screwed into the first screw 7 to achieve locking and fixing of the mobile phone holder. Of course, the nut 4 can also be rotated and screwed into the first screw 7 while the first screw 7 on the mobile phone holder 6 enters the nut mounting groove 3 through the mounting screw hole 2 to tighten and fix it.

[0022] Preferably, the nut 4 is a hand-tightened nut.

[0023] Preferably, the nut mounting slot 3 is a through slot hole.

[0024] Optionally, in order to facilitate the quick connection and fast fixation of various devices on the handle, a cold shoe slot used for connecting photographic equipment to each other in the prior art can also be provided on the handle body.

[0025] Example 2

[0026] As attached Figure 4 As shown, this embodiment retains other technical features on the basis of the original embodiment 1, and at the same time, a first screw hole 11 is provided on the other side of the handle body opposite to the side where the mounting screw hole 2 is located. The first screw hole 11 penetrates from the side opposite to the mounting screw hole to the nut mounting groove. The first screw hole 11 can be screwed into the second screw 9. The second screw 9 is provided with a first thread 10, which can be connected with the nut 4. The second screw 9 can ensure that the nut 4 can be screwed on the second screw 9 when nothing is connected to the mounting screw hole 2, thereby ensuring that the nut 4 will not fall off easily due to not being fixed on the corresponding screw. When an object is connected to the mounting screw hole 2, the nut 4 can be rotated to move upward and connected to the screw of the corresponding object to achieve locking and fixing.

[0027] Optionally, the mounting screw hole 2 on the handle body 1 may also be a fully threaded through hole extending downward. In this case, when the mounting screw hole 2 is a fully threaded through hole extending downward, the bottom screw hole of the mounting screw hole 2 will be equivalent to the function of the first screw hole 11, and the second screw 9 can also be screwed into this screw hole to fix the nut 4.

[0028] Example 3

[0029] As attached Figure 5As shown, in this embodiment, based on the original embodiment 1, the nut mounting groove 3 originally located on the handle body 1 is changed into a third screw hole 14. The third screw hole 14 can be screwed into the third screw 12. The third screw 12 is a stop screw. The third screw 12 is provided with a second thread 13, and the second thread 13 can be screwed into the third screw hole 14. When the screw of the corresponding object is screwed into the mounting screw hole 2 on the handle body 1, the third screw 12 is tightened to further fix the corresponding connection.

[0030] Preferably, the third screw 12 is a hand screw.

[0031] Preferably, the third screw 12 is a set screw with a rubber or nylon material on the head.

[0032] Example 4

[0033] As attached Figure 6 As shown, in order to solve the problem that the nut 4 is easy to fall out of the nut installation groove, there is another embodiment. Based on the original embodiment 1, this embodiment is provided with a groove 15 and a stud 16 located in the center of the groove 15 on the inner bottom surface of the nut installation groove 3. The groove 15 can be used for the nut 4 to be placed therein, and the thread size of the stud 16 matches the size of the thread 8 on the nut 4. The nut 4 can be screwed into the stud 16. When nothing is connected to the handle, the nut 4 can be screwed onto the stud 16 and a part of the height is sunk into the groove 15. When an object is connected to the handle, the nut 4 can be screwed out upwards and screwed into the screw of the corresponding object to achieve locking.
