Description

Technical Field

[0001] This utility model relates to the field of computer memory technology, specifically to an external computer memory. Background Technology

[0002] The main function of computer memory is to store data or programs. Computer memory includes the computer's built-in memory and auxiliary external computer memory, such as USB flash drives and portable hard drives, which facilitate the use of the operator. However, during the use of USB flash drives, dust can get into the plug, which will affect the subsequent use of the USB flash drive. In order to overcome the above defects, the prior art (Chinese patent application with application number 201220384446.5 and application date of 2012-08-06) is a USB flash drive with a flip-up protective cover. When in use, the protective cover is first pulled out horizontally to pull out the USB plug, but it does not detach from the USB flash drive body. It has the advantages of traditional flip-up covers, which are flexible to use and the protective cover is not easy to lose. At the same time, it can protect the USB plug from dirt entering the USB plug.

[0003] During use, the protective cover is engaged by friction of its own material. As a result, the protective cover may slide open automatically during use. The device in the above application does not have a stable engaging structure. When the protective cover slides open automatically, it will affect the user's use and allow dust to enter the USB flash drive, which will affect the subsequent reading and writing of the USB flash drive and cause unnecessary trouble. Utility Model Content

[0004] The purpose of this utility model is to provide an external computer storage device to solve the problem mentioned in the background art that does not have an stable locking structure. When the protective cover slides open automatically, it will affect the user's use and allow dust to enter the USB flash drive, which will affect the subsequent reading and writing of the USB flash drive and cause unnecessary trouble.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an external computer memory, including a main memory, a protective cover snapped onto the surface of the main memory, a connecting rope connecting the main memory and the protective cover, and an external plate fixedly connected to the surface of the protective cover; a vertical rod slidably disposed inside the main memory, and a push rod slidably disposed inside the main memory; a limit block fixedly connected to the surface of the push rod, and the limit blocks are symmetrically distributed on both sides of the push rod; an external plate fixedly connected to the surface of the protective cover, and a long pin fixedly connected to the surface of the external plate.

[0006] Preferably, the long pins are symmetrically distributed on both sides of the protective cover, and the surface of the main memory has mating holes that correspond one-to-one with the long pins.

[0007] Preferably, the outer side of the end of the vertical rod is inclined, and protrusions are fixedly connected to both the front and rear sides of the vertical rod, and the surface of the long pin is provided with a groove corresponding to the vertical rod.

[0008] Preferably, a connecting spring that provides elastic reset is fixedly connected to the upper surface of the protrusion, and the other side of the connecting spring is fixedly connected to the inner wall of the main memory.

[0009] Preferably, the end of the vertical rod is located outside the main memory, and a connecting rod is fixedly connected between adjacent vertical rods.

[0010] Preferably, the main memory has a limiting groove inside that corresponds one-to-one with the limiting block, and the inner wall of the main memory is in contact with the surface of the push rod.

[0011] Preferably, an auxiliary spring is fixedly connected to the surface of the push rod to assist in disassembly, and the other side of the auxiliary spring is fixedly connected to the inner wall of the main memory.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This external computer memory adopts a novel structural design, the specific details of which are as follows:

[0013] When the external computer memory needs to be connected to the main memory with a protective cover, simply align the long pin with the docking hole and insert it into the hole. The vertical rod will then be pushed, causing the protrusion to press against the connecting spring. After the long pin contacts the bottom of the docking hole, the vertical rod and the slot are in the same vertical direction. At this point, the vertical rod, under the action of the protrusion and the connecting spring, enters the slot, thus connecting the protective cover to the main memory. The operation is quick and convenient, and the protective cover will not slide open automatically.

[0014] Furthermore, the design of the long pin and the mating hole allows operators to align the parts more quickly, facilitating installation.

[0015] When the protective cover of this external computer memory needs to be removed, the connecting rod can be pulled to move the vertical rod upwards. Eventually, the end of the vertical rod moves out of the slot, and the protective cover and the main memory are no longer locked together. This allows the protective cover and the main memory to be separated directly, resulting in high work efficiency.

[0016] Furthermore, after the protective cover and main memory are separated, the connecting rope prevents the protective cover from falling off and being left behind, thus improving stability.

[0017] (3) During the docking process of the external computer memory, the end of the long pin will push the push rod, causing the end of the push rod to move in the direction of squeezing the auxiliary spring. That is, during the docking process of the protective cover and the main memory, the auxiliary spring is always in a squeezed state. Then, after the connecting rod drives the end of the vertical rod to move out of the slot, the push rod and the auxiliary spring will push the long pin, causing the long pin to move to the outside of the main memory, which facilitates the disassembly of the long pin and the protective cover and improves work efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0027] This utility model provides the following technical solution: an external computer memory.

[0028] Example 1: The protective cover 2 can be quickly engaged with the main memory 1 via the long pin 4, vertical rod 8, and slot 6. Figures 1-5 As shown, the device includes a main memory 1, a protective cover 2 that is snapped onto the surface of the main memory 1, a connecting rope 5 that connects the main memory 1 and the protective cover 2, and an external plate 3 that is fixedly connected to the surface of the protective cover 2; a vertical rod 8 that is slidably disposed inside the main memory 1, and a push rod 11 that is slidably disposed inside the main memory 1; an external plate 3 that is fixedly connected to the surface of the protective cover 2, and a long pin 4 that is fixedly connected to the surface of the external plate 3.

[0029] Long pins 4 are symmetrically distributed on both sides of the protective cover 2. The surface of the main memory 1 is provided with mating holes 7 corresponding to the long pins 4. The outer side of the end of the vertical rod 8 is inclined, and protrusions 9 are fixedly connected to both the front and rear sides of the vertical rod 8. The surface of the long pins 4 is provided with slots 6 corresponding to the vertical rod 8. A connecting spring 10 that plays an elastic reset role is fixedly connected to the upper surface of the protrusion 9, and the other side of the connecting spring 10 is fixedly connected to the inner wall of the main memory 1.

[0030] When the protective cover 2 is needed to protect the main memory 1, align the long pin 4 with the docking hole 7 and insert the long pin 4 into the docking hole 7. During the docking process, the surface of the long pin 4 will push the inclined surface of the vertical rod 8, causing the vertical rod 8 to move the protrusion 9 in the direction of squeezing the connecting spring 10. After the long pin 4 contacts the bottom of the docking hole 7, the vertical rod 8 and the slot 6 are in the same vertical direction. At this time, under the action of the protrusion 9 and the connecting spring 10, the vertical rod 8 enters into the slot 6, thus docking the protective cover 2 onto the main memory 1. The operation process is quick and convenient, and the protective cover 2 will not slide open automatically. The setting of the long pin 4 and the docking hole 7 allows the operator to align it more quickly and facilitates installation.

[0031] Example 2: Unlike Example 1, the connecting rod 15 allows the end of the vertical rod 8 to be quickly moved out of the slot 6, facilitating the removal of the protective cover 2 by the operator. Figure 6 As shown, the end of the vertical rod 8 is located outside the main memory 1, and a connecting rod 15 is fixedly connected between adjacent vertical rods 8.

[0032] When it is necessary to remove the protective cover 2, the connecting rod 15 can be pulled to move the vertical rod 8 upward. Finally, the end of the vertical rod 8 moves out of the slot 6. At this time, the protective cover 2 and the main memory 1 are no longer engaged, so the protective cover 2 and the main memory 1 can be directly separated. The working efficiency is high. After the protective cover 2 and the main memory 1 are separated, the connecting rope 5 plays a role in preventing the protective cover 2 from falling, which improves stability.

[0033] Example 3: Unlike Example 2, the push rod 11 and auxiliary spring 12 assist in disassembly, improving the work efficiency of the staff. Figure 7 As shown, a limiting block 13 is fixedly connected to the surface of the push rod 11, and the limiting blocks 13 are symmetrically distributed on both sides of the push rod 11; the main memory 1 has a limiting groove 14 corresponding to the limiting block 13, and the inner wall of the main memory 1 is in contact with the surface of the push rod 11. An auxiliary spring 12 that plays an auxiliary disassembly role is fixedly connected to the surface of the push rod 11, and the other side of the auxiliary spring 12 is fixedly connected to the inner wall of the main memory 1.

[0034] During the docking process of the long pin 4, the end of the long pin 4 will push the push rod 11, causing the end of the push rod 11 to move in the direction of squeezing the auxiliary spring 12. That is, during the docking process of the protective cover 2 and the main memory 1, the auxiliary spring 12 is always in a squeezed state. Then, after the connecting rod 15 drives the end of the vertical rod 8 to move out of the slot 6, the push rod 11 and the auxiliary spring 12 will push the long pin 4, causing the long pin 4 to move to the outside of the main memory 1, which facilitates the disassembly of the long pin 4 and the protective cover 2 and improves the work efficiency. At this time, the auxiliary spring 12 plays the role of assisting disassembly, while the limiting block 13 and the limiting groove 14 prevent the push rod 11 from moving excessively and improve stability.

[0035] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
