Description

Technical Field

[0001] The invention relates to a computer data interface anti-misinsertion safety lock and processing equipment thereof, belonging to the technical field of network security equipment. Background Art

[0002] Computer security locks are blocking devices that are plugged into computer network cable sockets, USB ports and other interfaces. They are widely used in various scenarios that require protection of network interfaces and data.

[0003] The commonly used blocking devices in the market can be applied to various types of interfaces, but the blocking devices of each interface, their lock holes and the key structure specifications they are equipped with are different, resulting in each interface requiring a different key to unlock, which is more troublesome to operate. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a computer data interface anti-misinsertion safety lock and processing equipment thereof, which solves the problem of too many types of lock holes of the safety lock in the prior art.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical scheme: a computer data interface anti-misinsertion safety lock, comprising: a lock head, plugged into the computer data interface, the lock head comprising a shell lock body, the shell lock body being plugged into the computer interface and having a lock hole on one side facing the outside of the computer interface, the lock hole being cross-shaped;

[0006] A key, used to unlock the lock and including a head and a tail;

[0007] The head comprises a hollow rod, a cavity is arranged in the middle of the hollow rod, one end of the hollow rod is rotatably connected to a cross head, and the other end is open;

[0008] The tail portion comprises a solid rod, one end of which is provided with a threaded head, and the other end of which is connected with a handle, and the threaded head is inserted from the open end of the hollow rod and then threadedly connected with the cross head;

[0009] Among them, the lock is an integrated structure and is integrally injection molded by processing equipment.

[0010] By adopting the above technical solution, the lock hole on the lock is set into a unified cross-shaped structure, and with the cross head on the key, multiple types of locks can be unlocked with the same key, without the need to equip each lock with a different unlocking key. At the same time, the key is divided into two parts, the head and the tail, and the head key and the tail key can be stored separately when necessary. When unlocking is required, the head and the tail of the key can be spliced ​​together to unlock, which reduces the risk of the data interface being accidentally opened and improves the security of the data interface.

[0011] Computer data interface anti-misinsertion safety lock processing equipment, including: a support frame, the support frame includes two support side plates, and the outer sides of the two support side plates are respectively provided with a driving source and a mold assembly;

[0012] A feed pipe is mounted between two supporting side plates, with both ends passing through the supporting side plates and connected to the driving source and the mold assembly respectively. The feed pipe is provided with an inner cavity, and a spiral column for feeding plastic particles is provided through the inner cavity. A heating body is provided on the sliding sleeve of the feed pipe;

[0013] A lifting platform is arranged below the feed pipe, and two sets of conveyor belts with opposite movement directions are arranged on the lifting platform, and the conveyor belts are used to push the heating body to reciprocate on the feed pipe;

[0014] A feed assembly is arranged above the driving source, and a feed pipe is connected between the feed assembly and the inner cavity of the feed pipe.

[0015] By adopting the above technical scheme, an integrally formed lock head can be quickly processed by injection molding. The inner cavity of the feed tube can be quickly heated by the heater arranged on the feed tube. During the heating process, the heater is driven to reciprocate on the feed tube by the conveyor belt. When a single lock head needs to be injected, the movement speed of the heater is controlled to be the same as the feeding speed of the plastic particles in the inner cavity of the feed tube, so that the plastic in the feeding process can always be in a heated state. When this section of plastic particles is injected after being heated, the heater is controlled to move back to the initial point. When the heated plastic particles are injected, the heater just moves to the initial point. When multiple lock heads need to be injected, the heater is controlled to reciprocate on the feed tube, thereby realizing continuous and rapid injection. There is no need to set multiple heating devices on the feed tube, so that the inside of the feed tube can be fully heated, which reduces the energy loss of the entire device. Only a single heating source is set, which reduces the manufacturing cost of the entire device.

[0016] The present invention is further configured as follows: a thermal insulation airbag is provided on the outer wall surface of the feed pipe between the supporting side plate and the heating body; wherein the thermal insulation airbags at the left and right ends of the heating body are compressed and expanded as the heating body moves, and the gas in the compressed thermal insulation airbag passes through the inner cavity of the heating body and enters into the expanded thermal insulation airbag.

[0017] By adopting the above technical solution, the temperature in the inner cavity of the feed tube can be always maintained through the heat-insulating airbag. During the movement of the heating body, the temperature in the inner cavity of the section of the feed tube that is not in contact with the heating body will not drop rapidly, so that the plastic particles in the feed tube can be melted quickly, avoiding the situation where the plastic particles in the feed tube are not fully melted due to uneven heat. Secondly, during the movement of the heating body, the gas inside the compressed heat-insulating airbag will pass through the heating coil inside the heating body before entering the expanded heat-insulating airbag. After contacting the heating coil, the temperature can be increased, so that the gas entering the heat-insulating airbag of the expanded gas can also maintain a higher temperature.

[0018] The present invention is further configured as follows: a driver is provided at both ends of the lifting platform, a transmission slot is provided on the lifting platform, the transmission belt moves in the transmission slot, mounting rods of different lengths are extended outward from both ends of the transmission slot, a rotating roller is provided between the mounting rod and the driver, and the transmission belt is driven by the rotating roller;

[0019] Wherein, a pushing plate is connected to the conveyor belt, and an abutment piece is arranged on the heating body. After the pushing plate and the abutment piece are in contact with each other, the heating body and the conveyor belt are pushed to move synchronously.

[0020] By adopting the above technical solution, the pushing plate provided on the conveyor belt and the abutment on the heating body are fitted together, so that the heating body can move synchronously with the conveyor belt. During the reciprocating motion of the heating body, only the pushing plate on one side of the conveyor belt fits together with the abutment at a time, and the pushing plate on the other side of the conveyor belt moves synchronously below the conveyor belt. When the heating body is pushed to the end of one end of the lifting platform, due to the different lengths of the mounting rods extending from both ends of the lifting platform for mounting the rotating rollers, a longer mounting rod and a shorter mounting rod are extended from the same end of the lifting platform, so that one of the rotating rollers at the same end of the lifting platform is farther away from the end of the lifting platform, and the other is closer to the end of the lifting platform, so that the pushing plate can push the heating body to the end of the lifting platform and separate from the abutment. The pushing plate separated from the abutment piece moves to the bottom of the conveyor belt via the roller near the end of the lifting platform. At this time, the pushing plate on the other side of the conveyor belt moves to the upper position of the conveyor belt via the rotating roller on the side farther from the end of the lifting platform, and fits with another abutment piece on the heating body to push the heating body back. By cooperating with the abutment pieces of the two sets of conveyor belts with opposite movement directions, the entire driving device does not need to control the forward and reverse rotation, and can directly control the reciprocating speed of the heating body by controlling the driving speed of the driver, without the need to set up a cumbersome driving program.

[0021] The present invention is further configured as follows: the abutment member includes a stopper connected to the outer shell of the heating body, a slider is slidably arranged on the stopper, and the sliding fitting surface between the slider and the stopper is an inclined surface. After the push plate is fitted with the slider, the slider will slide downward along the inclined surface so that the lower end of the slider downwardly abuts against the conveyor belt.

[0022] By adopting the above technical solution, the abutment is arranged into two parts. After the push plate and the abutment are fitted together, the slider can be pushed to slide downward along the inclined surface, so that the slider and the conveyor belt fit together, making the fit between the abutment, the push plate and the conveyor belt tighter, thereby preventing separation during the movement of the heating body by the push plate, thereby improving the overall stability of the driving component.

[0023] The present invention is further configured as follows: a return spring is connected between the stop block and the slider, and when the push block is separated from the slider, the return spring pulls the slider back to an initial state, at which time the slider is not in contact with the conveyor belt.

[0024] By adopting the above technical solution, the slider can be pulled back to the initial state by the reset spring, thereby preventing the conveyor belt on the side not attached to the push plate from contacting the slider and causing an increase in friction.

[0025] The present invention is further configured as follows: a limiting plate is provided on the outer wall surface of the feed pipe, and a limiting groove which is mutually engaged with the limiting plate is provided on the inner ring of the heating body.

[0026] By adopting the above technical solution, the heating body can be prevented from rotating during movement, causing the abutment member and the push plate to separate from each other, thereby limiting the movement direction of the heating body, making the movement path of the heating body more accurate, and improving the stability of the device.

[0027] The present invention is further configured as follows: a mounting groove is provided on the plate surface of the limiting plate, and the side edge of the heat-insulating airbag is slidably engaged with the mounting groove provided on the plate surface of the limiting plate.

[0028] By adopting the above technical solution, the side of the thermal insulation airbag is slidably engaged with the installation groove on the limit plate, so that the middle part of the thermal insulation airbag will not bulge outward when it shrinks. The installation groove plays a limiting role on the thermal insulation airbag, so that the thermal insulation airbag can stably fit on the outer wall surface of the feed tube regardless of expansion or contraction, thereby transferring temperature to the inner cavity of the feed tube.

[0029] The present invention is further configured as follows: a replaceable mold is provided on the mold assembly, and the mold includes an RJ45 network port lock mold, a USB interface lock mold, a Type-C interface lock mold, and an SFP optical port lock mold.

[0030] By adopting the above technical solution, multiple molds can produce multiple types of interface locks, and the internal clamping structure of each interface lock is the same, so that different types of interface locks obtained after injection molding can be unlocked using the same key. Users only need to save one key to unlock multiple locks, which greatly facilitates user use.

[0031] The beneficial effect of the present invention is that the lock holes on different types of locks are injection molded into the same structure, so that after the locks of various types are plugged into different types of data interfaces, they can be removed using the same key, which is convenient for users.

[0032] By dividing the key into a head and a tail, the lock can only be unlocked when the head and the tail are combined with each other, and after the head and the tail are separated, they can be kept separately. Therefore, when unlocking is required, two key custodians are required to verify at the same time, which effectively improves the confidentiality and security of the lock.

[0033] Various types of locks can be quickly injection molded through the processing equipment. By setting the heating body in the processing equipment, the processing equipment does not need to attach multiple heating devices to the outer wall of the feed tube. Only one heating body is needed to heat the entire inner cavity of the feed tube, which reduces energy consumption and improves energy utilization. At the same time, the setting of a single heating body greatly reduces the production cost of the entire equipment.

[0034] By cooperating with the abutment member arranged on the heating body and the push plate member arranged on the conveyor belt, the heating body can realize reciprocating motion on the feed tube through the movement of the conveyor belt. There is no need to control the forward and reverse rotation of the driver. The heating body is driven to move by two sets of conveyor belts with opposite movement directions, so that there is no need to set the driving program when driving the heating body to move.

[0035] By setting up the heat preservation airbag, the heat emitted by the heating body can be kept near the outer wall of the feed pipe, so that the energy utilization rate is maximized. The heat preservation airbag limits the high-temperature gas to the outer wall of the feed pipe, so that the high-temperature gas fully contacts the wall of the feed pipe, thereby playing a good role in heat preservation of the inner wall of the feed pipe.

DETAILED DESCRIPTION

[0047] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0048] like Figure 1As shown, the computer data interface anti-misinsertion safety lock includes: a lock head 1, which is plugged into the computer data interface, and the lock head 1 includes a shell lock body 101. After the shell lock body 101 is plugged into the computer interface, a lock hole 102 is provided on the side facing the outside of the computer interface, and the lock hole 102 is in a cross shape; it also includes a key 2 for unlocking the lock head 1; wherein the lock head 1 is an integrated structure, and is integrally injection molded by an injection molding device.

[0049] When the lock 1 is in use, the user directly inserts the lock 1 into the corresponding data interface. When the lock 1 makes a clicking sound during the insertion process, it means that the data interface is successfully blocked.

[0050] like Figure 3 As shown, when the lock 1 needs to be pulled out from the data interface, the cross head 2012 on the key 2 is aligned with the cross-shaped lock hole 102 on the lock 1 and inserted. Since the cross head 2012 extends outward at different lengths in the vertical direction, after the user holds the handle 2023 of the key 2 and rotates it ninety degrees, the clamping structure in the lock 1 can be pushed by the longer part of the cross head 2012 and pushed toward the inside of the lock 1, thereby disengaging the clamping structure on the lock 1 from the data interface, and then the key 2 is pulled outward. Since the cross-shaped lock hole 102 corresponds to the cross head 2012, when the cross head 2012 is rotated ninety degrees with the key 2, the longer section of the cross head 2012 is stuck in the shorter section of the cross-shaped lock hole 102, thereby the entire lock 1 can be pulled out by pulling the key 2.

[0051] By setting the cross-shaped lock hole 102 and the cross head 2012, the length of the cross head 2012 extending outward is set to different lengths, so that after the cross head 2012 is inserted into the lock hole 102, it can be rotated ninety degrees and the cross head 2012 can be immediately snap-fitted into the inside of the lock head 1, so that the lock head 1 can be quickly pulled out of the data interface. At the same time, various types of data interfaces require lock heads 1 with various external interfaces. Through the processing equipment of the lock head 1, the lock heads 1 required for various data interfaces can be quickly injection-molded in one piece, and the internal snap-fit ​​structure of each type of lock head 1 can be injection-molded into the same snap-fit ​​structure, so that users can unlock different types of lock heads 1 with one key 2, which greatly facilitates user use.

[0052] It should be noted that the key 2 includes a head 201 and a tail 202; the head 201 includes a hollow rod 2011, a cavity is provided in the middle of the hollow rod 2011, one end of the hollow rod 2011 is rotatably connected to a cross head 2012, one end of the cross head 2012 located inside the hollow rod 2011 extends with a threaded connection section, and the other end is open; the tail 202 includes a solid rod 2021, one end of the solid rod 2021 is provided with a threaded head 2022, the center of the threaded head 2022 is provided with a threaded hole, and the other end is connected with a grip 2023, the threaded head 2022 is inserted from the open end of the hollow rod 2011 and is threadedly connected to the cross head 2012;

[0053] By configuring the key 2 to be divided into two parts, when the key 2 needs to be used, the head 201 and the tail 202 of the key 2 need to be spliced ​​together before the key 2 can be used normally. When splicing the key 2, first insert the solid rod 2021 of the tail 202 into the inner cavity of the hollow rod 2011 of the head 201. When the threaded head 2022 of the tail 202 contacts the cross head 2012, pinch the handle 2023 and rotate the cross head 2012 so that the cross head 2012 is inserted into the threaded head 2022 of the tail 202. Since the threaded head 2022 is provided with a threaded hole, the cross head 2012 can be fastened with the threaded head 2022. After the head 201 is connected to the tail 202 , the cross head 2012 is inserted into the corresponding lock hole 102 . The handle 2023 needs to be pinched and rotated, and the rotation direction is opposite to the thread rotation direction of the thread head 2022 and the cross head 2012 , and the lock head 1 is pulled out with the complete key 2 .

[0054] Embodiment 1:

[0055] like Figure 1 As shown, in this embodiment, the lock head 1 is applied to the RJ45 network interface, and the outer shell lock body 101a is composed of four vertical plates 1011 and an elastic plate 1012. One side of the elastic plate 1012 is connected to the vertical plate 1011, and the other side is connected with a groove 1013, and the groove 1013 is directly opposite to the cross-shaped lock hole 102a.

[0056] After the lock 1 is inserted into the RJ45 network interface, the lock 1 is pressed against the inner wall of the RJ45 network interface by the elastic plate 1012 to complete the blocking. When the lock 1 needs to be pulled out from the RJ45 network interface, the cross head 2012 is inserted and rotated so that the longer section of the cross head 2012 pushes the elastic plate 1012 toward the inside of the lock 1, thereby separating the elastic plate 1012 from the inner wall of the RJ45 network interface, so that the lock 1 can be quickly pulled out.

[0057] Embodiment 2:

[0058] like Figure 2As shown, in this embodiment, the lock head 1 is applied to the SFP optical port, and the shape of the second housing lock body 101b is injection molded into the same structure as the SFP optical port connector, and can be fully inserted into the SFP network port to block the SFP optical port. A second cross-shaped lock hole 102b with the same shape as the cross head 2012 is provided on the wall of the lock head 1 facing the outside of the SFP optical port.

[0059] Embodiment three:

[0060] like Figure 4 As shown, in this embodiment, the lock head 1 is applied to the USB interface, and the structure of the outer shell lock body 3 101c is the same as that of the USB plug, and can be completely inserted into the USB data interface to block the USB data interface. A cross-shaped lock hole 3 102c with the same shape as the cross head 2012 is provided on the wall of the lock head 1 facing the outside of the USB interface.

[0061] Embodiment 4:

[0062] In this embodiment, the lock head 1 is applied to the Type-C interface, and the outer structure of the lock head is injection molded to be the same as the outer structure of the Type-C plug, and can be completely inserted into the Type-C data interface to block the Type-C data interface. A cross-shaped jack with the same shape as the cross head 2012 is provided on the wall of the lock head 1 facing the outside of the Type-C interface. When unlocking is required, the cross head is inserted into the jack, rotated 90 degrees and pulled out.

[0063] like Figure 6 As shown, the processing equipment of the computer data interface anti-misinsertion safety lock is used for processing the above-mentioned computer data interface anti-misinsertion safety lock, including: a support frame 4, the support frame 4 includes two support side plates 401, and the outer sides of the two support side plates 401 are respectively provided with a driving source 5 and a mold assembly 6; a feed pipe 7, which is erected between the two support side plates 401, and the two ends pass through the support side plates 401 and are respectively connected to the driving source 5 and the mold assembly 6, the feed pipe 7 is provided with an inner cavity, and a spiral column for feeding plastic particles is penetrated in the inner cavity, and a heating body 8 is slidably sleeved on the feed pipe 7; a lifting platform 9, which is arranged below the feed pipe 7, and two groups of conveyor belts 10 with opposite movement directions are arranged on the lifting platform 9, and the conveyor belt 10 is used to push the heating body 8 to reciprocate on the feed pipe 7; a feeding assembly 11, which is arranged above the driving source 5, and a feeding pipe 12 is connected between the feeding assembly 11 and the inner cavity of the feed pipe 7.

[0064] During the injection molding process of the lock head 1, the plastic particles in the feed assembly 11 are transported to the feed pipe 7 through the feed pipe 12, and the plastic particles are pushed to move by the threaded feed rod in the feed pipe 7. The threaded feed rod is driven to rotate by the driving source 5. At the same time, the heating body 8 mounted on the outer wall of the feed pipe 7 moves synchronously with the plastic particles and heats the plastic particles to melt them into a gel state, and finally they are ejected through the injection head at the end of the feed pipe 7 and enter the mold for cooling and molding.

[0065] The reciprocating motion of the heating body 8 reduces the heating source required for the entire processing equipment, reducing the manufacturing cost. The heating body 8 slidably arranged on the feed pipe 7 can heat the plastic particles in the inner cavity of the entire feed pipe 7, thereby improving energy utilization.

[0066] Furthermore, an insulation airbag 13 is provided on the outer wall of the feed pipe 7 between the supporting side plate 401 and the heating body 8; wherein, the insulation airbags 13 at the left and right ends of the heating body 8 are compressed and expanded as the heating body 8 moves, and the gas in the compressed insulation airbag 13 passes through the inner cavity of the heating body 8 and enters into the expanded insulation airbag 13.

[0067] By arranging a heat-insulating airbag 13 on the feed pipe 7, the heat generated by the heating body 8 can be concentrated on the outer wall of the feed pipe 7, so that the temperature in the inner cavity of the feed pipe 7 can be maintained in a relatively stable state, and the temperature will not dissipate too quickly; secondly, during the movement of the heating body 8, the heat-insulating airbag 13 with the same movement direction as the heating body 8 is compressed, and the internal airflow passes through the heating source inside the heating body 8 and enters the heat-insulating airbag 13 on the other side of the heating body 8. This ensures that the airflow inside the heat-insulating airbags 13 on both sides of the heating body 8 will be reheated every time the heating body 8 reciprocates, thereby ensuring that the section of the feed pipe 7 that is not in contact with the heating body 8 can maintain a relatively stable temperature transfer, and the flowing airflow can improve the efficiency of heat transfer, so that the temperature inside the feed pipe 7 rises faster.

[0068] like Fig. 9 As shown, the movement of the heating body 8 is driven by two groups of conveyor belts 10 with opposite movement directions, and the number of conveyor belts 10 in each group is at least one.

[0069] Furthermore, a transmission groove 901 is symmetrically arranged on the lifting platform 9, and mounting rods 902 of different lengths extend outward from both ends of the transmission groove 901, and the conveyor belt 10 moves in the transmission groove 901; a driver 3 is arranged at both ends of the lifting platform 9, and a rotating roller 903 is arranged between the mounting rod 902 and the driver 3, and the rotating roller 903 is used to drive the conveyor belt 10.

[0070] Specifically, each conveyor belt 10 is connected and fixed with a pushing plate 1001, and the heating body 8 corresponding to the position of the conveyor belt 10 is connected with an abutment piece 801 that abuts against the pushing plate 1001. When the conveyor belt 10 is moving, the pushing plate 1001 and the abutment piece 801 fit together to push the entire heating body 8 to move.

[0071] It should be noted that, since the two mounting rods 902 extending outward from the end of the lifting platform 9 are of different lengths, the conveyor belts 10 on both sides of the lifting platform 9 can move different distances outward from the end of the lifting platform 9, and each time the pushing plate 1001 pushes the heating body 8 to move, it moves toward the shorter end of the mounting rod 902, and the pushing plate 1001 on the other side of the conveyor belt 10 is located below the conveyor belt 10 and moves toward the longer end of the mounting rod 902. When the heating body 8 is pushed to one end of the lifting platform 9 by the conveyor belt 10, the pushing plate 1001 and the abutment 801 are separated from each other, and the pushing plate 1001 on the other side of the conveyor belt 10 just moves to the top of the conveyor belt 10, and continues to fit with the other abutment 801 on the heating body 8, pushing the heating body 8 to move in the other direction, and repeats this process to realize the reciprocating motion of the heating body 8 on the feed pipe 7.

[0072] By setting up two groups of conveyor belts 10 with opposite movement directions, the reciprocating motion of the heating body 8 can be directly realized without programming the driver 3 or controlling the forward and reverse rotation of the driver, which facilitates the operation steps of the device. At the same time, the movement speed of the heating body 8 can also be directly achieved by controlling the rotation of the driver 3 and thereby adjusting the movement speed of the conveyor belt 10.

[0073] In particular, such as Figure 7 As shown, the abutment member 801 includes a stopper 8011 connected to the outer shell of the heating body 8, and a slider 8012 is slidably arranged on the stopper 8011. The sliding contact surface between the slider 8012 and the stopper 8011 is inclined. After the pushing block 1001 is fitted with the slider 8012, the slider 8012 will slide downward along the inclined surface so that the lower end of the slider 8012 will abut against the conveyor belt 10 downward.

[0074] Specifically, a slide groove 8110 is provided on the inclined surface of the stopper 8011 that is attached to the slider 8012, a guide rod 8120 is provided in the slide groove 8110, and a return spring 8130 is sleeved on the guide rod 8120. A clamping block 8140 extends outward from one end of the attached inclined surface of the slider 8012, which is used to be slidably connected in the slide groove 8110, and the clamping block 8140 is provided with a sliding cavity 8150, and the guide rod 8120 slides in the sliding cavity 8150 of the clamping block 8140.

[0075] When the pushing plate 1001 and the abutting member 801 are in contact with each other, the pushing plate 1001 will push the slider 8012 to slide downward along the inclined surface, so that the end of the slider 8012 is in close contact with the conveyor belt 10, thereby making the contact between the abutting member 801 and the conveyor belt 10 closer.

[0076] like Figure 8 As shown, a return spring 8130 is connected between the stopper 8011 and the slider 8012. When the push plate 1001 is separated from the slider 8012, the return spring 8130 pulls the slider 8012 back to the initial state, and at this time, the slider 8012 is not in contact with the conveyor belt 10. The return spring 8130 can pull the slider 8012 back to the initial state, which can prevent the conveyor belt 10 that is not attached to the push plate 1001 from contacting the slider 8012 and causing the friction force to increase.

[0077] like Fig. 9 As shown, a limit plate 701 is provided on the outer wall of the feed pipe 7, and a limit groove 802 is provided on the inner ring of the heating body 8 to engage with the limit plate 701. The heating body 8 can reciprocate along the axis of the feed pipe 7 without rotating, thereby ensuring that the contact between the push plate 1001 and the abutment member 801 will not be laterally separated, making the entire transmission path more stable.

[0078] Furthermore, the plate surface of the limiting plate 701 is provided with a mounting groove, and the side edge of the heat preservation airbag 13 is slidably engaged with the mounting groove provided on the plate surface of the limiting plate 701. The side edge of the heat preservation airbag 13 is slidably engaged with the mounting groove on the limiting plate 701, so that the middle part of the heat preservation airbag 13 does not bulge outward when it shrinks, and the mounting groove plays a limiting role on the heat preservation airbag 13, so that the heat preservation airbag 13 can be stably attached to the outer wall surface of the feed pipe 7 whether in the process of expansion or contraction.

[0079] It should be noted that the mold assembly 6 is provided with replaceable molds, including RJ45 network port lock mold, USB interface lock mold, Type-C interface lock mold, and SFP optical port lock mold. Various molds can produce various types of interface locks 1, and the internal clamping structure of each interface lock 1 is the same, so that different types of interface locks 1 obtained after injection molding can be unlocked using the same key 2. Users only need to save one key 2 to unlock multiple locks 1, which greatly facilitates user use.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
