Description

Technical Field

[0001] This utility model relates to the field of locking mechanisms, specifically a data cable locking mechanism for portable hard drives. Background Technology

[0002] A portable hard drive is a type of external storage device, typically consisting of a mechanical hard drive or a solid-state drive core encased in a protective shell and an interface module. It connects to a computer or other devices via USB, Thunderbolt, or other data cables to store and transfer large amounts of data. A portable hard drive needs to be connected to a computer / device via a data cable.

[0003] In existing technologies, since the data cable and the external hard drive are simply connected by a plug, it has been found in use and observation that when working in environments prone to turbulence, such as airplanes and high-speed trains, the external hard drive may experience relative movement, which can cause the data cable to loosen and affect the hard drive's data read and write operations.

[0004] Therefore, a data cable locking mechanism for portable hard drives is proposed to address the above issues. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The mobile hard drive data cable locking mechanism of this utility model includes a hard drive body, a data cable is provided on one side of the hard drive body, the data cable includes a plug and a cable; a connecting plate is fixedly connected to the outer wall of the plug; a toothed plate is symmetrically fixedly connected to the connecting plate on the side facing the hard drive body; the top of the toothed plate is composed of a ramp section and a ratchet section; a housing is symmetrically fixedly connected to the middle of the hard drive body; the toothed plate and the housing are in sliding fit; a pull rod is slidably connected through the top of the housing; a guide wheel is rotatably connected to the bottom of the pull rod; through the cooperation of the guide wheel and the toothed plate, when the data cable is loose, it can be limited by the guide wheel applied to the toothed plate, thereby improving the stability of the data cable during operation.

[0007] Preferably, a connecting rod is fixed between the tops of the pair of pull rods; by setting the connecting rod, when the user unplugs the data cable, the pair of pull rods can be operated simultaneously by pulling up the connecting rod, simplifying the tedious operation of pulling the pull rods at the same time.

[0008] Preferably, a spring is fixed between the pull rod and the top of the box. When the toothed plate is not inside the box, the spring is in its normal state. As the toothed plate lifts the guide wheel, the spring is stretched and provides a restoring force to the pull rod. This allows the guide wheel to accelerate its return under the weight of the pull rod and the spring force, ensuring that the guide wheel can quickly abut against the top of the toothed plate.

[0009] Preferably, a positioning plate is fixedly connected to the top of the plug; a positioning frame is fixedly connected to one side of the hard drive body; the positioning plate and the positioning frame are correspondingly set; by setting the positioning plate, before the plug is inserted into the internal interface of the hard drive body, the user can quickly know the orientation of the plug by observing the positioning plate, which facilitates the subsequent docking of the plug with the hard drive body and the docking of the toothed plate with the housing. In addition, the positioning plate can engage with the positioning frame, which can further improve the stability when the data cable is inserted into the hard drive body.

[0010] Preferably, a silicone sheath is provided on the surface of the cable and one side of the connecting plate; by providing the silicone sheath, the silicone sheath can wrap and protect the weak section at the connection between the cable and the plug, and the high elasticity of the silicone sheath itself can buffer the stress when the cable is bent, prevent the internal wires from breaking, and extend the service life of the data cable.

[0011] Preferably, a pair of ribs are fixed to the surface of the silicone sheath; an elastic clip is sleeved between the pair of ribs; by setting the elastic clip, the ribs can position the elastic clip through the cooperation of the elastic clip and the ribs, and the elastic clip will clamp the silicone sheath and the cable wrapped inside under the action of elasticity, so as to improve the surface rigidity of the cable at the plug connection and reduce the bending situation during use.

[0012] The advantages of this utility model are:

[0013] 1. The data cable locking mechanism for portable hard drives described in this utility model, through the cooperation of the guide wheel and the toothed plate, can limit the data cable when it is loose by the guide wheel applying the limiting effect to the toothed plate, thereby improving the stability of the data cable during operation.

[0014] 2. The data cable locking mechanism for portable hard drives described in this utility model, by setting a connecting rod, allows users to simultaneously operate a pair of levers by pulling up the connecting rod when unplugging the data cable, simplifying the cumbersome operation of simultaneously lifting the levers.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1 to 5As shown in the embodiment of this utility model, the data cable locking mechanism for a portable hard drive includes a hard drive body 1. A data cable is provided on one side of the hard drive body 1, and the data cable includes a plug 12 and a cable 13. A connecting plate 14 is fixedly connected to the outer wall of the plug 12. A toothed plate 16 is symmetrically fixedly connected to the side of the connecting plate 14 facing the hard drive body 1. The top of the toothed plate 16 consists of a ramp section and a ratchet section. A housing 15 is symmetrically fixedly connected to the middle of the hard drive body 1. The toothed plate 16 and the housing 15 are in sliding fit. A pull rod 17 is slidably connected to the top of the housing 15. A guide wheel 18 is rotatably connected to the bottom of the pull rod 17. Before plugging the data cable into the interface of the hard drive body 1, the pair of toothed plates 16 on the connecting plate 14 can be aligned with the housing 15 on the hard drive body 1. After alignment, the data cable can be pushed so that the toothed plates 16 enter the housing 15. During the process, the guide wheel 18 can first contact and rotate with the ramp section of the toothed plate 16, and the pull rod 17 can... The guide wheel 18 is lifted by the cooperation of the toothed plate 16. Then, the guide wheel 18 can slide along the ratchet on the toothed plate 16. When the toothed plate 16 is fully inserted into the housing 15, that is, when the plug 12 of the data cable is inserted into the interface of the hard drive body 1, the guide wheel 18 can abut against the back of the ratchet on the toothed plate 16. When the working environment of the hard drive body 1 is bumpy, the connection between the data cable and the hard drive body 1 may loosen. At this time, the plug 12 and the connecting plate 14 can remain stable under the limiting action of the guide wheel 18 on the toothed plate 16, that is, to ensure a stable connection between the data cable and the hard drive body 1. When it is necessary to disconnect the data cable and the hard drive body 1, simply pull up a pair of levers 17 to stop limiting the toothed plate 16, and the data cable can be pulled out from one side of the hard drive body 1. Through the cooperation of the guide wheel 18 and the toothed plate 16, when the data cable is loose, it can be limited by the limiting action of the guide wheel 18 on the toothed plate 16, thereby improving the stability of the data cable during operation.

[0025] Please see Figure 2 As shown, a connecting rod 2 is fixedly connected between the tops of the pair of pull rods 17; by setting the connecting rod 2, when the user unplugs the data cable, the pair of pull rods 17 can be operated simultaneously by pulling up the connecting rod 2, simplifying the tedious operation of pulling the pull rods 17 at the same time.

[0026] Please see Figure 3 As shown, a spring 3 is fixed between the pull rod 17 and the top of the box 15. When the toothed plate 16 is not inside the box 15, the spring 3 is in its normal state. Subsequently, as the toothed plate 16 lifts the guide wheel 18, the spring 3 can be stretched. The spring 3 can provide a restoring force to the pull rod 17, so that the guide wheel 18 can be accelerated to return to its original state under the action of the gravity of the pull rod 17 and the elastic force of the spring 3, ensuring that the guide wheel 18 can quickly abut against the top of the toothed plate 16.

[0027] Please see Figure 1 and Figure 2As shown, a positioning plate 4 is fixedly connected to the top of the plug 12; a positioning frame 42 is fixedly connected to one side of the hard disk body 1; the positioning plate 4 and the positioning frame 42 are correspondingly set; by setting the positioning plate 4, before the plug 12 is inserted into the internal interface of the hard disk body 1, the user can quickly know the orientation of the plug 12 by observing the positioning plate 4, which facilitates the subsequent docking of the plug 12 with the hard disk body 1 and the docking of the toothed plate 16 with the housing 15. In addition, the positioning plate 4 can engage with the positioning frame 42, which can further improve the stability when the data cable is inserted into the hard disk body 1.

[0028] Please see Figure 4 and Figure 5 As shown, a silicone sleeve 5 is provided on the surface of the cable 13 and one side of the connecting plate 14. By providing the silicone sleeve 5, the silicone sleeve 5 can wrap and protect the weak section at the connection between the cable 13 and the plug 12. The high elasticity of the silicone sleeve 5 can buffer the stress when the cable 13 is bent, prevent the internal wires from breaking, and extend the service life of the data cable.

[0029] Please see Figure 5 As shown, a pair of ribs 62 are fixed to the surface of the silicone sheath 5; an elastic clip 6 is sleeved between the pair of ribs 62; by setting the elastic clip 6, the ribs 62 can position the elastic clip 6 through the cooperation of the elastic clip 6 and the ribs 62, and the elastic clip 6 will clamp the silicone sheath 5 and the internally wrapped cable 13 under the action of elastic force, so as to improve the surface rigidity of the cable 13 at the connection of the plug 12 and reduce the bending situation during use.

[0030] Working principle: Before plugging the data cable into the interface of the hard drive body 1, align the pair of toothed plates 16 on the connecting plate 14 with the housing 15 on the hard drive body 1. After alignment, push the data cable so that the toothed plates 16 enter the housing 15. During this process, the guide wheel 18 can first contact and rotate with the ramp section of the toothed plate 16. The pull rod 17 can be lifted by the cooperation of the guide wheel 18 and the toothed plate 16. Then, the guide wheel 18 can slide along the ratchet on the toothed plate 16. When the toothed plate 16 is fully inserted into the housing 15, that is, when the plug 12 of the data cable is inserted into the interface of the hard drive body 1, the guide wheel 18 can abut against the back of the ratchet on the toothed plate 16. When the working ring of the hard drive body 1... When the environment is bumpy, the connection between the data cable and the hard drive body 1 may loosen. At this time, the plug 12 and the connecting plate 14 can remain stable under the limiting action of the guide wheel 18 on the toothed plate 16, thus ensuring a stable connection between the data cable and the hard drive body 1. When it is necessary to disconnect the data cable from the hard drive body 1, simply pull up a pair of levers 17 to stop limiting the toothed plate 16, and the data cable can be pulled out from one side of the hard drive body 1. By setting the connecting rod 2, when the user pulls up the connecting rod 2, both levers 17 can be operated simultaneously, simplifying the cumbersome operation of simultaneously pulling the levers 17. By setting the spring 3, the toothed plate 1... When the 6 is not inside the housing 15, the spring 3 is in its normal state. Subsequently, as the toothed plate 16 lifts the guide wheel 18, the spring 3 is stretched. The spring 3 provides a restoring force to the pull rod 17, allowing the guide wheel 18 to accelerate its return under the weight of the pull rod 17 and the elastic force of the spring 3, ensuring that the guide wheel 18 can quickly abut against the top of the toothed plate 16. By setting the positioning plate 4, before the plug 12 is inserted into the internal interface of the hard drive body 1, the user can quickly determine the orientation of the plug 12 by observing the positioning plate 4, which facilitates the subsequent docking of the plug 12 with the hard drive body 1 and the toothed plate 16 with the housing 15. In addition, the positioning plate 4 can engage with the positioning frame 42. The connection further improves the stability of the data cable when inserted into the hard drive body 1; by setting the silicone sleeve 5, the silicone sleeve 5 can wrap and protect the weak section at the connection between the cable 13 and the plug 12. The high elasticity of the silicone sleeve 5 can buffer the stress when the cable 13 is bent, prevent the internal wires from breaking, and extend the service life of the data cable; by setting the elastic clip 6, through the cooperation of the elastic clip 6 and the rib 62, the rib 62 can position the elastic clip 6, and the elastic clip 6 will clamp the silicone sleeve 5 and the internally wrapped cable 13 under the action of elastic force, so as to improve the surface rigidity of the cable 13 at the connection of the plug 12 and reduce the bending situation during use.
