Description

Technical Field

[0001] This application relates to the field of outdoor equipment technology, and more specifically, to an unpacking tool. Background Technology

[0002] Outdoor-deployed equipment, due to its sealing requirements, is typically housed within a chassis. The chassis generally consists of a first and second enclosure that interlock, with the seam sealed with adhesive. When the equipment needs maintenance, this type of chassis requires opening the sealed enclosure.

[0003] The most commonly used sealant is silicone rubber. Silicone rubber has high weather resistance and strong adhesion, but it requires considerable force to peel off the cured adhesive. Under normal circumstances, without suitable tools, opening a sealed chassis outdoors requires a long time and a lot of effort.

[0004] like Figure 1 As shown, the existing unpacking tools include a flathead screwdriver 02 and a hammer 03. When unpacking is required, first align the flathead screwdriver 02 with the seam of the chassis 01, then use the hammer 03 to chisel the flathead screwdriver 02 into the chassis seam. After the flathead screwdriver 02 has penetrated to a certain depth into the chassis seam, shake the flathead screwdriver 02 to widen the gap. Then change the position and repeat the above actions until multiple gaps are widened around the chassis, making it possible to open the chassis manually.

[0005] Existing unpacking tools require the flathead screwdriver 02 to be repeatedly moved during unpacking, which is time-consuming and laborious. The vibration generated when the hammer 03 strikes the flathead screwdriver 02 can easily cause the flathead screwdriver 02 to come off the seam of the chassis 01, causing the flathead screwdriver 02 to hit the paint surface of the chassis 01, inevitably damaging the paint surface and even creating dents.

[0006] Therefore, how to facilitate the unpacking operation while improving the safety of the unpacking operation and preventing damage to the paint surface of the chassis is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] In view of this, the purpose of this application is to provide an unpacking tool to facilitate unpacking operations, improve safety during unpacking operations, and prevent damage to the chassis paint.

[0008] To achieve the above objectives, this application provides the following technical solution:

[0009] The first aspect of this application provides an unpacking tool for assisting in opening a chassis, the chassis including a first housing and a second housing, the first housing being provided with a first positioning part and the second housing being provided with a second positioning part;

[0010] The unpacking tools include:

[0011] A first support member and a second support member, wherein one of the first support member and the second support member is positioned at the first positioning part, and the other is positioned at the second positioning part;

[0012] A driving component is used to drive the first support member and the second support member to move closer to each other and further away from each other.

[0013] In one possible implementation, the driving component is a piston cylinder, which includes a cylinder body and a piston rod, wherein one of the first support member and the second support member is fixed to the cylinder body and the other is fixed to the piston rod.

[0014] In one possible implementation, the driving element is a worm gear mechanism, which includes a meshing worm wheel and a worm. The worm is rotatably engaged with one of the first support member and the second support member, and the worm wheel is rotatably engaged with the other of the first support member and the second support member.

[0015] In one possible implementation, the driving element is a lead screw, and at least one of the first support member and the second support member is threadedly engaged with the lead screw. When the lead screw rotates in a first direction, the first support member and the second support member move closer to each other, and when the lead screw rotates in a second direction, the first support member and the second support member move further apart from each other.

[0016] In one possible implementation, one of the first support member and the second support member is threadedly engaged with the lead screw, and the other is rotatably connected to the lead screw.

[0017] In one possible implementation, the lead screw includes a first helical thread segment and a second helical thread segment with opposite helical directions, the first support member is threadedly engaged with the first helical thread segment, and the second support member is threadedly engaged with the second helical thread segment.

[0018] In one possible implementation, the first support member is provided with a first positioning groove on the side away from the second support member, and the first positioning groove is configured to position and cooperate with the first positioning part.

[0019] The second support member has a second positioning groove on the side away from the first support member, and the second positioning groove is configured to position and cooperate with the second positioning part.

[0020] In one possible implementation, the unpacking tool further includes a guide rod, one end of which is fixed to one of the first support member and the second support member and slidably engaged with the other, the guide rod being parallel to the lead screw.

[0021] In one possible implementation, there are at least two guide rods, and two of the guide rods are respectively arranged on both sides of the lead screw;

[0022] and / or;

[0023] The guide rod is fixed to the first support member by a guide rod fastener, and the second support member has a guide rod guide hole that slides with the guide rod.

[0024] In one possible implementation, the unpacking tool further includes a lead screw rotation handle fixed to the lead screw.

[0025] In one possible implementation, the lead screw rotation handle is fixed to the lead screw by a handle fastener;

[0026] The lead screw rotary handle has a limiting hole, and one end of the lead screw has a limiting part that cooperates with the limiting hole. The limiting part has a mounting screw hole.

[0027] The lead screw rotating handle has a mounting hole that communicates with the limiting hole. The handle fastener passes through the mounting hole and is threaded into the mounting screw hole.

[0028] In one possible implementation, the unpacking tool further includes a handle fixed to one of the first support and the second support, located at an end remote from the chassis.

[0029] In one possible implementation, the first support member is provided with a first weight-reducing hole, and the second support member is provided with a second weight-reducing hole;

[0030] and / or;

[0031] Both the first positioning part and the second positioning part are chassis handles;

[0032] and / or;

[0033] Both the first support member and the second support member are made of aluminum alloy.

[0034] The unpacking tool provided in this application, when an unpacking operation is required, drives the first and second support members closer together until they are respectively positioned on the first positioning part of the first housing and the second positioning part of the second housing. Then, the drive unit drives the first and second support members away from each other, gradually expanding and pressing against the first and second positioning parts. The drive unit continues to drive the first and second support members to widen the housing seam. Then, the drive unit drives the first and second support members closer together and withdraws from the first and second positioning parts, finally allowing the housing to be fully opened manually.

[0035] The unpacking tool provided in this application utilizes a drive mechanism to slowly and evenly separate the first and second enclosures, minimizing damage to the enclosure's appearance and preserving its good looks, preventing damage to the paint finish. This drive mechanism allows for smooth opening of the enclosure, reducing impact on the internal structure, lowering the risk of damage to internal components, ensuring normal equipment operation, and improving safety during unpacking. Compared to prying open with a flathead screwdriver, using the drive mechanism to separate the enclosures requires less hand strength. Attached Figure Description

[0055] This application discloses an unpacking tool to facilitate unpacking operations, improve safety during unpacking, and prevent damage to the chassis paint.

[0056] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the application as described in the claims. Additionally, the complete composition represented in the embodiments below is not limited to what is necessary as the solution to the application described in the claims. It should be noted that, for ease of description, only the parts relevant to the application are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0057] like Figures 2-5 As shown in the figure, this application discloses an unpacking tool, which is used to assist in opening the chassis 800 (e.g., Figure 6 As shown, the chassis 800 includes a first housing and a second housing. A first positioning part 801 is provided on the first housing, and a second positioning part 802 is provided on the second housing. The first positioning part 801 and the second positioning part 802 can be a chassis handle, or they can be other structures of the first housing and the second housing.

[0058] The unpacking tool disclosed in this application includes a first support member 100, a second support member 200, and a driving member. One of the first support member 100 and the second support member 200 is positioned on a first positioning part 801, and the other is positioned on a second positioning part 802. For example, the first support member 100 is positioned on the first positioning part 801, and the second support member 200 is positioned on the second positioning part 802. Alternatively, the first support member 100 can be positioned on the second positioning part 802, and the second support member 200 can be positioned on the first positioning part 801.

[0059] The driving component is used to drive the first support member 100 and the second support member 200 to move closer to each other and further apart. The driving component can be a piston cylinder (not shown in the figure), which includes a cylinder body and a piston rod. One of the first support member 100 and the second support member 200 is fixed to the cylinder body, and the other is fixed to the piston rod. When the piston rod extends, it can cause the first support member 100 and the second support member 200 to move away from each other; when the piston rod retracts, it can cause the first support member 100 and the second support member 200 to move closer to each other.

[0060] The driving component can also be a worm gear mechanism, which includes a meshing worm gear and a worm. The worm is rotatably engaged with one of the first support member 100 and the second support member 200, and the worm gear is rotatably engaged with the other of the first support member 100 and the second support member 200. When the worm rotates in one direction, it can drive the first support member 100 and the second support member 200 away from each other; when the worm rotates in the opposite direction, it can drive the first support member 100 and the second support member 200 closer to each other.

[0061] The driving component can also be a lead screw 300. The following is a detailed introduction to the solution using a lead screw 300 as the driving component. Of course, piston cylinders and worm gear mechanisms can also achieve the same technical effects.

[0062] At least one of the first support member 100 and the second support member 200 is threadedly engaged with the lead screw 300. That is, both the first support member 100 and the second support member 200 can be threadedly engaged with the lead screw 300, or one of them can be threadedly engaged with the lead screw 300 while the other is not. Regardless of the connection method used, as long as it can be ensured that changing the rotation direction of the lead screw 300 can control the first support member 100 and the second support member 200 to move closer to each other or further apart, it is acceptable.

[0063] For example, when the lead screw 300 rotates in the first direction, the first support member 100 and the second support member 200 move closer to each other; when the lead screw 300 rotates in the second direction, the first support member 100 and the second support member 200 move further apart. Rotating the lead screw 300 in the first direction allows the first support member 100 and the second support member 200 to move closer together, while rotating it in the second direction allows them to move further apart. The first and second directions are opposite directions, one being clockwise and the other counterclockwise.

[0064] The unpacking tool disclosed in this application, when an unpacking operation is required, rotates the lead screw 300 in a first direction, causing the first support member 100 and the second support member 200 to move closer together (e.g., ...). Figure 6 As shown), until the distance between the first support member 100 and the second support member 200 is less than the distance between the first positioning part 801 and the second positioning part 802, so that the first support member 100 and the second support member 200 can be positioned on the first positioning part 801 of the first housing and the second positioning part 802 of the second housing, respectively.

[0065] like Figure 7 As shown, the lead screw 300 is then rotated in the second direction, causing the first support member 100 and the second support member 200 to move away from each other, gradually expanding and pressing against the first positioning part 801 and the second positioning part 802. Figure 8 As shown, continue rotating the lead screw 300 in the second direction until the first support member 100 and the second support member 200 expand the joint of the chassis 800. Then rotate the lead screw 300 in the first direction so that the first support member 100 and the second support member 200 move closer to each other and are removed from the first positioning part 801 and the second positioning part 802. Finally, the chassis 800 can be fully opened manually.

[0066] The unpacking tool disclosed in this application utilizes a lead screw 300 to slowly and evenly apply pulling force, causing the first and second housings to separate. This minimizes damage to the appearance of the chassis 800, maintaining its good appearance and preventing damage to the paint. The lead screw 300 transmission method allows for smooth opening of the chassis 800, reducing impact on the internal structure, lowering the risk of damage to internal components, ensuring normal equipment operation, and improving safety during unpacking operations.

[0067] Rotating the lead screw 300 separates the first and second housings, requiring less hand strength compared to prying them open with a flathead screwdriver. This is especially beneficial for the firmly glued chassis 800, where a screwdriver requires considerable force; the lead screw 300 utilizes the effort-saving principle of the thread, making operation easier and more convenient for opening the housings. The lead screw 300 precisely controls the movement distance and speed of the first support component 100 and the second support component 200. Operators can slowly and steadily separate the first and second housings as needed, stopping or adjusting the operation at any time.

[0068] The lead screw 300 drive mechanism for opening the chassis 800 causes relatively little damage to the adhesive seal. When resealing the chassis 800 is required, it can be easily accomplished with simple adjustments. Prying it open with a screwdriver, however, may damage the structure at the chassis seams, making resealing difficult.

[0069] During the process of opening the chassis 800 by rotating the lead screw 300, the strength and condition of the adhesive seal can be felt through the rotation of the lead screw 300, so as to understand the sealing condition in advance and provide a reference for subsequent maintenance and sealing treatment. It is difficult to obtain this information by prying it open with a screwdriver.

[0070] The unpacking tool disclosed in this application is not a controlled device restricted by public transportation and can be easily carried on board or checked in. Furthermore, the main components of this application are made of aluminum alloy to ensure the overall lightweight nature of the tool and reduce carrying burden. For example, the first support member 100 has a first weight-reducing hole 104, and the second support member 200 has a second weight-reducing hole 204; both the first support member 100 and the second support member 200 are made of aluminum alloy.

[0071] In one specific embodiment of this application, one of the first support member 100 and the second support member 200 is threadedly engaged with the lead screw 300, and the other is rotatably connected to the lead screw 300. For ease of understanding, the example given is that the first support member 100 is threadedly engaged with the lead screw 300, and the second support member 200 is rotatably connected to the lead screw 300.

[0072] The first support member 100 has a support member screw hole 103 that mates with the threaded section of the lead screw 300, and the lead screw 300 has a smooth shaft section. The second support member 200 has a support member smooth hole 203 that mates with the smooth shaft section of the lead screw 300. During installation, washers 604 can be placed on the upper and lower sides of the second support member 200. The lead screw 300 passes through the upper washer 604, the support member smooth hole 203, and the lower washer 604 in sequence, and is then connected to the locking thread end of the lead screw 300 by a limit nut 605, thus connecting the second support member 200 and the lead screw 300. It should be noted that the limit nut 605 only needs to perform a limiting function, that is, to prevent the second support member 200 from disengaging from the lead screw 300, without locking, ensuring that the lead screw 300 can rotate relative to the second support member 200.

[0073] This embodiment is more flexible in design, allowing for the selection of which of the first support member 100 and the second support member 200 is threaded onto the lead screw 300, and which is rotatably engaged with the optical shaft section, based on the structure of the chassis 800, installation space, and actual usage requirements. This enables the unpacking device to better adapt to chassis of different specifications and structures, expanding the device's application range and versatility.

[0074] This embodiment has lower processing requirements for the lead screw 300, eliminating the need to machine two sections of threads with different helix directions, thus reducing the manufacturing cost of the lead screw 300. Using the more common and lower-cost lead screw 300 while ensuring the unpacking function helps control the overall production cost of the unpacking device and improves product competitiveness.

[0075] In another embodiment of this application, the lead screw 300 includes a first helical thread segment and a second helical thread segment with opposite helical directions, the first support member 100 is threadedly engaged with the first helical thread segment, and the second support member 200 is threadedly engaged with the second helical thread segment.

[0076] When the lead screw 300 rotates, the first support 100 and the second support 200 move along the first and second threaded sections with opposite directions of rotation, respectively, achieving precise simultaneous and opposite movements with excellent synchronicity. This characteristic ensures that the chassis 800 is evenly stressed on both sides, maintaining balance and stability during opening and preventing deformation of the chassis 800 or damage to internal components due to uneven force. The threaded drive itself has high precision, and the movement of the first support 100 and the second support 200 is directly controlled by the thread of the lead screw 300. As long as the machining precision of the lead screw 300 is sufficient, the movement accuracy of the first support 100 and the second support 200 can be guaranteed, precisely controlling the distance change between the first support 100 and the second support 200, meeting the application scenarios with precise requirements for the opening position of the chassis.

[0077] To facilitate the positioning of the first support member 100 and the first positioning part 801, a first positioning groove 101 is provided on the side of the first support member 100 away from the second support member 200. The first positioning groove 101 is configured to cooperate with the first positioning part 801 in positioning.

[0078] To facilitate the positioning of the second support member 200 and the second positioning part 802, a second positioning groove 201 is provided on the side of the second support member 200 away from the first support member 100. The second positioning groove 201 is configured to cooperate with the second positioning part 802 in positioning.

[0079] Taking the use of the unpacking tool with the first support member 100 on the upper side and the second support member 200 on the lower side as an example, the first positioning groove 101 is located on the upper side of the first support member 100, and the second positioning groove 201 is located on the lower side of the second support member 200. The first positioning groove 101 is engaged with the lower side of the first positioning part 801, and the second positioning groove 201 is engaged with the upper side of the second positioning part 802.

[0080] During the process of the lead screw 300 driving the first support member 100 and the second support member 200 to move closer or further apart, the positioning grooves (first positioning groove 101, second positioning groove 201) and positioning parts (first positioning part 801, second positioning part 802) can play an auxiliary positioning role. They can limit the offset and sway of the support members (first support member 100 and second support member 200) during the transmission process of the lead screw 300, and ensure that the first support member 100 and the second support member 200 maintain the positioning engagement with the first positioning part 801 and the second positioning part 802 during the movement, preventing the unpacking operation from being unable to continue due to disengagement.

[0081] The cooperation between the positioning grooves (first positioning groove 101, second positioning groove 201) and the positioning parts (first positioning part 801, second positioning part 802) effectively restricts the degrees of freedom of the support members (first support member 100 and second support member 200) in certain directions, so that the first support member 100 and the second support member 200 can only move relative to each other along the direction of transmission of the lead screw 300 during operation, reducing the impact of displacement or shaking in other directions on the opening operation.

[0082] In one specific embodiment of this application, the unpacking tool may further include a guide rod 400, one end of which is fixed to one of the first support member 100 and the second support member 200 and is slidably engaged with the other. The guide rod 400 is parallel to the lead screw 300.

[0083] Taking the guide rod 400 fixed to the first support member 100 as an example, the guide rod 400 is fixed to the first support member 100 by the guide rod fastener 602. The second support member 200 has a guide rod guide hole 202 that slides with the guide rod 400. For example, a fixing hole 102 can be provided on the first support member 100, and a guide rod screw hole can be provided at the end of the guide rod 400. A limiting step is provided in the fixing hole 102. The guide rod 400 is inserted into the fixing hole 102 from the bottom, and the guide rod fastener 602 is inserted into the fixing hole 102 from the top and threadedly engaged with the guide rod screw hole. When the guide rod fastener 602 is tightened, the nut of the guide rod fastener 602 and the cross-section of the guide rod 400 will abut against the upper and lower sides of the limiting step, respectively, thus realizing the installation of the guide rod 400 on the first support member 100.

[0084] It should be noted that the above example is only one specific installation method. This application is not limited to the fixing method of the guide rod 400 disclosed in the above embodiments. Those skilled in the art can select the corresponding fixing method of the guide rod 400 based on their needs.

[0085] The guide rod 400 provides precise guidance for the movement of the supports (first support 100 and second support 200), limiting any deviation or wobbling that may occur during the drive of the lead screw 300. This allows the first support 100 and the second support 200 to move closer or further apart in a predetermined direction more accurately, thereby improving the precision of the unpacking operation and enabling a more accurate opening of the chassis 800, preventing damage to the chassis 800 due to movement deviations of the first support 100 and the second support 200. When the lead screw 300 drives the first support 100 and the second support 200 to move closer or further apart, the guide rod 400 assists in guiding the movement, reducing wear on the lead screw 300, and extending its service life.

[0086] At least two guide rods 400 may be provided, with two of them arranged on both sides of the lead screw 300. This arrangement ensures that when the lead screw 300 is rotated, the torque exerted by the lead screw 300 on the first support member 100 (taking the threaded engagement between the lead screw 300 and the first support member 100 as an example) can be resisted by the guide rods 400 on both sides of the lead screw 300, thereby improving the stability of the first support member 100.

[0087] In one specific embodiment of this application, the unpacking tool may further include a lead screw rotation handle 500 fixed to the lead screw 300. The lead screw rotation handle 500 provides a point of force for manual operation of the lead screw 300. In some scenarios where electric or automated drive is not required, the operator can easily rotate the lead screw 300 by rotating the lead screw rotation handle 500, thereby driving the cooperating components to move, realizing functions such as adjusting the distance between the first support member 100 and the second support member 200, which is convenient, quick, and not limited by power supply conditions.

[0088] It should be noted that the lead screw 300 can also be connected to an electrically driven drive system.

[0089] To facilitate gripping the lead screw rotary handle 500, a finger groove 504 is provided on the handle 500 to mate with the fingers. The design of the finger groove 504 better conforms to the shape of the fingers, allowing the user's fingers to naturally fit into the finger groove 504 when rotating the lead screw rotary handle 500. This greatly increases the friction between the hand and the lead screw rotary handle 500, making the grip more stable and effectively preventing the hand from slipping off the lead screw rotary handle 500 during operation. Especially when a greater force is required to rotate the lead screw 300, it ensures the continuity and stability of operation.

[0090] The fingers can apply force more easily with the support provided by the finger groove 504, reducing hand fatigue and further improving the convenience of operation. Whether the person has great or little strength, they can drive the lead screw 300 to rotate relatively easily. The finger groove 504 enhances grip and effectively reduces the risk of slipping.

[0091] It should be noted that, in order to reduce the weight of the lead screw rotary handle 500, a third weight-reducing hole 503 is provided on the lead screw rotary handle 500. The lead screw rotary handle 500 can be made of aluminum alloy to reduce its weight.

[0092] In one specific embodiment of this application, the lead screw rotation handle 500 can be fixed to the lead screw 300 by a handle fastener 601. The lead screw rotation handle 500 has a limiting hole 501, which can be a hole with a non-circular cross-section.

[0093] One end of the lead screw 300 has a limiting part 301 that mates with the limiting hole 501. The limiting part 301 can be a non-circular cross-section structure that mates with the limiting hole 501. This allows the lead screw rotation handle 500 to transmit torque and drive the lead screw 300 to rotate without the need for other structures to fix it after the limiting part 301 mates with the limiting hole 501.

[0094] The limiting part 301 has a mounting screw hole 302. The lead screw rotating handle 500 has a mounting hole 502 that communicates with the limiting hole 501. The extending direction of the limiting hole 501 and the extending direction of the mounting hole 502 can be perpendicular. When the limiting part 301 is inserted into the limiting hole 501, the mounting screw hole 302 corresponds exactly to the mounting hole 502.

[0095] The handle fastener 601 passes through the mounting hole 502 and is threaded into the mounting screw hole 302. This design prevents the limiting part 301 from disengaging from the limiting hole 501, which would cause the screw rotation handle 500 to fall off and prevent the screw 300 from rotating.

[0096] In one specific embodiment of this application, the unpacking tool may further include a handle 700, which is fixed to one of the first support member 100 and the second support member 200, and located at the end away from the chassis 800. The outer surface of the handle 700 may be textured to increase the friction for hand gripping and provide an anti-slip effect. The handle 700 may be fixed to the first support member 100 by a handle fastener 603. The handle 700 may be made of aluminum alloy to reduce weight.

[0097] When using the unpacking tool, hold the handle 700 with one hand and rotate the screw to rotate the handle 500 with the other. First, adjust the distance between the first support 100 and the second support 200 according to the distance of the chassis handle to be disassembled, so that the first support 100 and the second support 200 can smoothly enter the range of the chassis handle. Figure 6 As shown.

[0098] The first support member 100 and the second support member 200 are inserted into the range of the chassis handle, so that the chassis handle enters the first positioning groove 101 of the first support member 100 and the second positioning groove 201 of the second support member 200, such as... Figure 7 As shown. Rotating the screw and handle 500 in the second direction will cause the first support 100 and the second support 200 to gradually expand and press against the chassis handle. Continue rotating the screw and handle 500 until the first support 100 and the second support 200 widen the chassis joint, as shown. Figure 8 As shown. At this point, rotate the screw and handle 500 degrees in the first direction to remove the unpacking tool, and then the chassis can be fully opened manually.
