Description

Technical Field

[0001] This utility model relates to the field of electronic equipment assembly technology, and in particular to a device suitable for positioning components of electronic equipment. Background Technology

[0002] In the manufacturing process of electronic devices, many components need to be assembled and secured. For example, heat sinks and chips, connectors and motherboards, etc., all need to be secured with fasteners. In order to improve production efficiency during the assembly process, manufacturers generally use positioning fixtures to fix the various components to be assembled, so as to achieve accurate positioning between the components, and then secure each component.

[0003] like Figure 14 As shown, a current positioning fixture used in the assembly process of electronic devices uses a conventional hinge 130' to connect a protective cover 120' and a bottom film 110', thus designing the protective cover 120' as a flip-top structure. Positioning of the product 200 is achieved by closing the protective cover 120' relative to the bottom film 110'. However, in this structural arrangement of the protective cover 120', it first contacts one end of the product 200 during the closing process, such as... Figure 15 As shown, there is an issue of uneven force on one side of product 200, which can easily lead to misalignment of product 200 and / or its connecting parts, such as misalignment of the connector pins of product 200. This reduces standardization and affects production efficiency.

[0004] Therefore, it is necessary to provide a positioning device that can balance the force on the product to prevent tilting, thereby solving the above problems. Utility Model Content

[0009] Preferably, the pivot assembly further includes a mounting base, which is fixed to the first cover plate, and both ends of the pivot shaft are mounted on the mounting base.

[0010] Preferably, the positioning device further includes a fastening assembly, which includes at least a locking member. The locking member is installed on one of the first cover plate and the second cover plate, and the locking member is provided with a first locking part. When the second cover plate is closed on the first cover plate, the first locking part is fastened to the other of the first cover plate and the second cover plate.

[0011] Preferably, the other of the first cover plate and the second cover plate is provided with a second locking part that cooperates with the first locking part. The first locking part and the second locking part can be separated and engaged to lock or release the closed first cover plate and the second cover plate.

[0012] Preferably, the cover plate assembly further includes a first sensor disposed on the first cover plate and / or the second cover plate, for detecting whether the first cover plate and the second cover plate are closed.

[0013] Preferably, the driving assembly includes a driving member and a first connecting member connected to the driving member. The first connecting member extends out of the bottom mold assembly and is connected to the first cover plate. The driving member drives the cover plate assembly to rise and fall through the first connecting member.

[0014] Preferably, the drive assembly further includes a second connector connected to the telescopic end of the drive assembly, and at least two first connectors are respectively connected to the second connector and the first cover plate, and the drive assembly drives each of the first connectors to move up and down through the second connector.

[0015] Preferably, the shape of the through hole corresponds to the shape of the support platform, and the inner diameter of the through hole is larger than the outer diameter of the support platform, so that the first cover plate can be raised and lowered along the support platform.

[0016] Preferably, the support platform is provided with a receiving groove, the shape of which corresponds to the shape of the product to be processed. The product can be positioned by placing it in the receiving groove, thereby reducing the risk of product damage.

[0017] Preferably, the receiving groove is provided with a positioning element for positioning the product.

[0018] Preferably, the positioning element protrudes into the receiving groove and corresponds to the positioning hole provided on the product.

[0019] Preferably, the bottom mold assembly further includes a second sensor, which is disposed on the support platform and used to detect the product on the support platform.

Specifically, it includes a first cover plate and a second cover plate pivotally connected to each other. The second cover plate can pivot relative to the first cover plate to close or open. The first cover plate has a through hole that can be fitted onto the support platform of the bottom mold assembly, and the second cover plate has multiple through-holes. A drive assembly connected to the cover plate assembly is also provided. Thus, after the product is placed on the support platform, the second cover plate is first pivoted to close onto the first cover plate. Then, the drive assembly drives the entire cover plate assembly to descend relative to the bottom mold assembly, allowing the second cover plate to press and hold the product on the support platform for positioning. During this process, the cover plate assembly descends vertically and presses against the product, resulting in a balanced downward pressure on the product, effectively preventing product tilting. Furthermore, the downward force and speed of the cover plate assembly are controllable, significantly improving the product processing yield. Based on this, the disassembly rate of the positioning device is correspondingly reduced, and the automatic lifting and lowering of the cover plate assembly significantly improves production efficiency, reduces the number of operators, and consequently lowers costs.

[0039] Embodiments of the present invention will now be described with reference to the accompanying drawings, in which similar element reference numerals represent similar elements. It should be noted that the directional descriptions involved in the present invention, such as up, down, left, right, front, and back, indicating directions or positional relationships, are based on the directions or positional relationships shown in the drawings and are only for the convenience of describing the technical solutions of this application or / and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first," "second," etc., described are only used to distinguish technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the sequential relationship of the indicated technical features.

[0040] First combine Figures 1-13 As shown, in one embodiment of this utility model, the positioning device 100 includes a bottom mold assembly 110, a drive assembly 120, and a cover plate assembly 130. The bottom mold assembly 110 is provided with a support platform 111 for supporting the product to be processed. The support platform 111 is flexibly configured according to the specific product being processed and is not limited in this application. The cover plate assembly 130 includes a first cover plate 131 and a second cover plate 132 pivotally connected to each other. The second cover plate 132 can pivot relative to the first cover plate 131 to close or open. Furthermore, the first cover plate 131 is provided with a through hole 1311 that can be fitted onto the support platform 111, and the second cover plate 132 has multiple through operating holes 1321 that can communicate with the through hole 1311. The drive assembly 120 is mounted on the bottom mold assembly 110 and connected to the first cover plate 131. It drives the cover plate assembly 130 to rise and fall relative to the bottom mold assembly 110, thereby allowing the second cover plate 132 to hold or detach the product placed on the support platform 111, achieving product positioning and release, as detailed below. This application uses the vertical rising and falling of the cover plate assembly 130 to hold and position the product, ensuring balanced force on the product and effectively preventing product tilting. This achieves high-precision product positioning and processing, improving the yield rate.

[0041] The following is combined Figure 1-4 , Figure 8 As shown, in one embodiment of this utility model, the support platform 111 protrudes from the top plate of the bottom mold assembly 110, and its shape is not limited. For example, Figure 8 The support platform 111 shown is roughly rectangular, but it is not limited to this. The support platform 111 is also provided with a receiving groove 1111, the shape of which corresponds to the shape of the product to be processed. Thus, when the product is placed in the receiving groove 1111, the sidewall of the receiving groove 1111 can initially position the product, ensuring not only the accuracy of the product's position but also reducing the risk of product damage.

[0042] See Figure 8 As shown, in a preferred embodiment, the support platform 111 is further provided with positioning elements 1112 for positioning the product, so as to achieve precise positioning of the product and facilitate subsequent processing. In a specific embodiment, multiple positioning elements 1112 protrude from the receiving groove 1111, each positioning element 1112 protruding from the bottom surface of the receiving groove 1111, and preferably having a cylindrical structure. The positions of each positioning element 1112 correspond to the positions of pre-set positioning holes on the product. Thus, after the product is placed in the receiving groove 1111, the positioning holes on it are aligned with the corresponding positioning elements 1112. The sidewall of the receiving groove 1111 and the positioning elements 1112 achieve precise positioning of the product and prevent product movement, thereby improving the processing accuracy of the product, as detailed later. It is understood that the positioning elements 1112 can also be configured in other structural forms or located in other positions on the support platform 111, as long as they can accurately position the product.

[0043] See below. Figure 8 As shown, in one embodiment of this utility model, the bottom mold assembly 110 further includes a second sensor 112, which is disposed on the support platform 111 and used to detect the product. In a specific embodiment, the second sensor 112 is disposed in the receiving groove 1111 to detect the product placed in the receiving groove 1111. Specifically, the bottom surface of the receiving groove 1111 is recessed with a second mounting hole 1113, and the second sensor 112 is received in the second mounting hole 1113, without protruding from the bottom surface of the receiving groove 1111. In this way, when the product is placed in the receiving groove 1111, the second sensor 112 can detect that the product has been placed in place, while avoiding the product from squeezing the second sensor 112 and causing damage. Of course, the second sensor 112 can also be installed in other positions on the support platform 111, as long as product detection can be achieved.

[0044] The following is combined Figures 5-7 As shown, in one embodiment of this utility model, a receiving cavity 113 is formed within the bottom mold assembly 110. This receiving cavity 113 is used to install the drive assembly 120, thereby protecting the drive assembly 120 and making the overall appearance of the positioning device 100 simple and aesthetically pleasing. The specific structure and shape of the bottom mold assembly 110 are not limited in this application. In addition, a start button, a reset button, and an indicator light are also provided on the outer wall of the bottom mold assembly 110. The start button, reset button, and indicator light are electrically connected to the control circuit. The arrangement of these components is conventional in the art and will not be described in detail.

[0045] In this embodiment, the structures of the other parts of the bottom mold assembly 110 are all conventional structures in the art.

[0046] The following is combined Figures 1-9 As shown, in one embodiment of this utility model, the shape of the through hole 1311 on the first cover plate 131 corresponds to the shape of the support platform 111, and the inner diameter of the through hole 1311 is larger than the outer diameter of the support platform 111. For example, the through hole 1311 can be set as a rectangle, and the inner diameter of the through hole 1311 is slightly larger than the outer diameter of the support platform 111. In this way, the first cover plate 131 can be sleeved on the support platform 111, so that the first cover plate 131 can be raised and lowered along the support platform 111, thereby enabling the entire cover plate assembly 130 to be raised and lowered vertically, and thus enabling the second cover plate 132 to be separably pressed onto the product. Of course, the through hole 1311 can be set to any shape, as long as it is ensured that the through hole 1311 can be sleeved on the support platform 111 to enable the first cover plate 131 to be raised and lowered.

[0047] In this embodiment, the first cover plate 131 has an elastic structure, for example, it is formed using a material with a certain degree of elasticity. This arrangement allows the first cover plate 131 to have a certain buffering effect after it descends vertically and presses against the top plate of the bottom mold assembly 110, thereby forming a buffer and protection for the product to prevent excessive downward pressure from damaging the product and / or the bottom mold assembly 110.

[0048] In this embodiment, the second cover plate 132 has a plate structure, and its shape and outer diameter preferably correspond to those of the first cover plate 131. Thus, when the second cover plate 132 is closed on the first cover plate 131, the edges of both are flush, which not only makes the overall appearance of the cover plate assembly 130 simple and aesthetically pleasing, but also prevents interference with other components. Of course, making the outer diameter of the second cover plate 132 smaller than that of the first cover plate 131, and ensuring that the second cover plate 132, when closed, can cover the through hole 1311 on the first cover plate 131 or extend into the through hole 1311, also allows the second cover plate 132 to hold the product placed on the support platform 111. Therefore, this structural arrangement is also feasible.

[0049] Continue to combine Figures 1-9 As shown, in one embodiment of this utility model, the positioning device 100 further includes a pivot assembly 140, which enables the pivoting of the first cover plate 131 and the second cover plate 132. Specifically, the pivot assembly 140 includes a pivot seat 141 and a pivot shaft 142 for pivotal engagement. The pivot seat 141 is installed on one of the first cover plate 131 and the second cover plate 132, and the pivot shaft 142 is installed on the other of the first cover plate 131 and the second cover plate 132.

[0050] Combination Figure 1-3 , Figure 8-9As shown, in one specific embodiment, the pivot seat 141 is mounted on the first cover plate 131, and the pivot seat 141 is provided with a pivot hole. The pivot shaft 142 is mounted on the second cover plate 132. For example, the pivot shaft 142 is integrally formed with the second cover plate 132, or it is formed separately and then fixed to the second cover plate 132. The two ends of the pivot shaft 142 are respectively pivotally connected to the pivot hole, thereby realizing the pivotal connection with the pivot seat 141. Of course, fixing the two ends of the pivot shaft 142 to the pivot seat 141 and simultaneously pivotally connecting the second cover plate 132 to the pivot shaft 142 can also realize the pivoting of the second cover plate 132. The structural arrangement in this specific embodiment makes the pivotal connection between the first cover plate 131 and the second cover plate 132 simpler and more convenient.

[0051] Continue to combine Figures 1-9 As shown, in one embodiment of this utility model, the positioning device 100 further includes a fastening assembly 150. The fastening assembly 150 is disposed at the end of the first cover plate 131 and the second cover plate 132 away from the pivot assembly 140, and is used to lock the closed first cover plate 131 and the second cover plate 132 and to allow them to be opened. Specifically, the fastening assembly 150 includes at least one locking member 151, which is installed on one of the first cover plate 131 and the second cover plate 132, and the locking member 151 is provided with a first locking portion 1511. When the second cover plate 132 is closed on the first cover plate 131, the first locking portion 1511 can abut against the other of the first cover plate 131 and the second cover plate 132, thereby locking the first cover plate 131 and the second cover plate 132.

[0052] Combination Figures 1-3 As shown, in a preferred embodiment, the fastening assembly 150 further includes a locking plate 152, which is installed on the other of the first cover plate 131 and the second cover plate 132. The locking plate 152 is provided with a second locking part 1521 that cooperates with the first locking part 1511. The second locking part 1521 and the first locking part 1511 protrude towards each other, and the second locking part 1521 can detachably abut against the first locking part 1511 to realize the locking or unlocking of the first cover plate 131 and the second cover plate 132.

[0053] Continue to combine Figure 1-3 , Figure 8-9As shown, in one specific embodiment, the locking member 151 is fixed to the first cover plate 131, and the protruding direction of the first locking part 1511 intersects with the moving path of the second cover plate 132, specifically intersecting with the surface where the first cover plate 131 is located. The locking plate 152 is fixed to the second cover plate 132. A locking hole 1322 is provided on the second cover plate 132, and the locking plate 152 is fixed to the second cover plate 132 and protrudes into the locking hole 1322. During the closing process of the second cover plate 132, the second locking part 1521 of the locking plate 152 can move downwards along the first locking part 1511. When an external force causes the second locking part 1521 to pass over the first locking part 1511, the second locking part 1521 abuts against the first locking part 1511, thereby locking the first cover plate 131 and the second cover plate 132. Correspondingly, when an external force pushes the second cover plate 132 upward, the second locking part 1521 can disengage from the first locking part 1511, thereby realizing the release between the first cover plate 131 and the second cover plate 132.

[0054] It is understandable that the second locking part 1521 is not limited to being formed by setting the locking member 151. The second locking part 1521 can be set as a part of the second cover plate 132. For example, the second locking part 1521 can be formed by protruding from the inner wall of the locking hole 1322 of the second cover plate 132.

[0055] See below. Figure 8 As shown, in one embodiment of the present invention, the cover plate assembly 130 further includes a first sensing element 133, which is disposed on the first cover plate 131 and / or the second cover plate 132, and is used to detect whether the first cover plate 131 and the second cover plate 132 are closed.

[0056] In one specific embodiment, a first mounting hole 1312 is provided on the frame of the first cover plate 131, and the first sensor 133 is accommodated in the first mounting hole 1312, without protruding from the frame surface of the first cover plate 131. Thus, after the second cover plate 132 is closed onto the first cover plate 131, the first sensor 133 can accurately detect that the second cover plate 132 is closed in place, while preventing the second cover plate 132 from crushing or damaging the first sensor 133. Of course, the first sensor 133 can also be installed in other ways.

[0057] The following is combined Figures 1-9 As shown, in this embodiment, when the cover assembly 130 is in use, after the fastening assembly 150 is released, the second cover 132 can pivotally open relative to the first cover 131, as... Figure 8As shown. At this time, the product can be placed into or removed from the support platform 111 through the through hole 1311 on the first cover plate 131. When the second cover plate 132 pivots and closes onto the first cover plate 131, the second locking part 1521 on the second cover plate 132 abuts against the first locking part 1511, thereby locking the first cover plate 131 and the second cover plate 132 in place. Figure 1-4 As shown. At this time, the first cover plate 131 and the second cover plate 132 are integrated and can be vertically raised and lowered under the drive of the drive component 120. The second cover plate 132 is used to hold the product for positioning. After processing, the product is removed by raising the drive component 120.

[0058] The following is combined Figures 5-7 As shown, in one embodiment of this utility model, the driving assembly 120 includes a driving member 123 and a first connecting member 121 connected to the driving member 123. The driving member 123 is housed in the receiving cavity 113 of the bottom mold assembly 110. The first connecting member 121 extends through the top plate of the bottom mold assembly 110 and connects to the first cover plate 131. The driving member 123 drives the cover plate assembly 130 to move vertically up and down through the first connecting member 121. To ensure balanced force on the cover plate assembly 130, at least two driving members 123 and at least two first connecting members 121 can be provided. The first connecting members 121 are connected to different positions on the first cover plate 131. Each driving member 123 synchronously drives the first connecting member 121 to move up and down, thereby driving the cover plate assembly 130 to move up and down.

[0059] Continue to combine Figures 5-7 As shown, in a preferred embodiment, the drive assembly 120 further includes a second connector 122 connected to the telescopic end of the drive assembly 123. At least two first connectors 121 are respectively connected to both ends of the second connector 122, and each second connector 122 passes through the top plate of the bottom mold assembly 110 and connects to at least both ends of the first cover plate 131. In this way, the drive assembly 123 simultaneously drives each first connector 121 to rise and fall synchronously through the second connector 122, and then each first connector 121 drives the cover plate assembly 130 to rise and fall vertically. This not only makes the force on the cover plate assembly 130 more balanced, thus making the vertical rise and fall more smoothly and further avoiding product tilting, but also simplifies the structure of the drive assembly 120.

[0060] In this embodiment, the drive component 123 is installed upside down, that is, the drive component 123 is fixed to the top plate of the bottom mold assembly 110 and its telescopic end protrudes downward. The second connector 122 is connected to the telescopic end and is located below the drive component 123. When the telescopic end of the drive component 123 extends, it pushes the second connector 122 to move downward, and then the second connector 122 drives the first connector 121 to descend. This structural arrangement makes the drive assembly 120 occupy less space and more convenient to install and operate within the limited accommodating cavity 113.

[0061] In this embodiment, the driving component 123 is preferably a cylinder, which simplifies the driving process and facilitates control over the force and speed at which the cover plate assembly 130 presses down. Of course, the driving component 123 is not limited to this; other easily controllable driving components can also be selected.

[0062] The following is combined Figures 4-7 As shown, in one embodiment of the present invention, the positioning device 100 further includes a guide component 160, which is disposed between the first cover plate 131 and the top plate of the bottom mold component 110. The guide component 160 is used to provide guidance for the vertical lifting and lowering of the cover plate component 130, thereby making the vertical lifting and lowering of the cover plate component 130 more stable, and thus making the downward pressure applied to the product more balanced and more effectively preventing the product from tilting.

[0063] In one embodiment, the guide assembly 160 includes a slidingly fitted guide rod 161 and a guide sleeve 162, with the guide rod 161 and guide sleeve 162 respectively mounted on the first cover plate 131 and the bottom mold assembly 110. For example, the guide sleeve 162 is fixed to the top plate of the bottom mold assembly 110, and the guide rod 161 is fixed to the first cover plate 131 and movably inserted into the guide sleeve 162. Of course, the installation method is not limited to the aforementioned method.

[0064] In a preferred embodiment, the guide assembly 160 is provided in multiple sets, which are evenly arranged around the first cover plate 131 and the bottom mold assembly 110, thereby making the vertical lifting and lowering of the cover plate assembly 130 more stable. For example, four sets of guide assemblies 160 are provided, with guide assemblies 160 provided at the four corners of the first cover plate 131 and the bottom mold assembly 110.

[0065] Combined again Figures 1-13 As shown, taking the locking of the first product and the second product as an example, the working principle and process of the positioning device 100 of this utility model will be explained. The first product and the second product can be any two components of an electronic device, for example, a motherboard and an adapter board, or a connector and a motherboard, etc., and are not limited in this application.

[0066] First, place the product on the bottom mold assembly 110. See details. Figure 8As shown, in the initial state, the cover plate assembly 130 is in the raised position, and the second cover plate 132 is pivotally opened relative to the first cover plate 131. At this time, the first product can be placed into the receiving groove 1111 of the support platform 111 through the through hole 1311 on the first cover plate 131. At the same time, the corresponding positioning hole on the first product passes through the positioning member 1112, and the positioning of the first product is achieved by using the inner wall of the receiving groove 1111 and the positioning member 1112. During this process, the second sensor 112 detects whether the product has been placed in place. Then, the second product is placed in the predetermined position of the first product, and the second product is precisely positioned relative to the first product. The position setting between the second product and the first product can be flexibly set according to the specific product.

[0067] Next, close the cover plate assembly 130. Specifically, first push the second cover plate 132 to pivot until it fits against the first cover plate 131. During this process, the second locking part 1521 on the second cover plate 132 will move downward along the inclined surface at the top of the locking member 151. Under the action of external force, the second locking part 1521 finally slides to the first locking part 1511 and abuts against the first locking part 1511. At this time, the locking plate 152 and the locking member 151 are locked together, thereby achieving the locking of the first cover plate 131 and the second cover plate 132. Figure 1-4 , Figure 10-11 As shown.

[0068] Then, press the start button on the bottom mold assembly 110. The control circuit controls the drive assembly 120 to start, causing the telescopic end of the drive member 123 to extend, thereby pushing the second connecting member 122 downward, as shown. Figure 7 As shown by the middle arrow, the second connector 122 drives each of the first connectors 121 to descend synchronously, and each of the first connectors 121 drives the cover plate assembly 130 to descend vertically to the predetermined position. The state at this time is as follows. Figure 12-13 As shown. At this time, the second cover plate 132 presses against the second product and the first product, and the cover plate assembly 130 achieves pre-pressing and positioning of the second product and the first product. During the vertical descent of the cover plate assembly 130 as a whole, the force and speed of the cover plate assembly 130 pressing down can be controlled by the drive component 123, thereby effectively avoiding product tilting or excessive pre-pressure, thus improving the processing accuracy of the product.

[0069] Next, the operator checks whether the operating hole 1321 on the second cover plate 132 is aligned and centered with the machining holes on the second and first products. If aligned, the second and first products are locked in place through the operating hole 1321. Figure 1-3 As shown. For example, screws are used to fasten the first product and the second product. Of course, if other processing operations are required between the first product and the second product, the corresponding operations can be performed through the operation hole 1321.

[0070] Finally, remove the processed product. (Specific details to follow) Figure 5-7 As shown, pressing the reset button on the bottom mold assembly 110 causes the control circuit to control the drive assembly 120 to run again. The telescopic end of the drive member 123 retracts, causing the second connecting member 122 to rise. The second connecting member 122 then drives the second connecting member 122 and the overall cover plate assembly 130 to rise, causing the cover plate assembly 130 to detach from the product. At this time, the cover plate assembly 130 moves to... Figure 1-4 , Figure 10-11 The state shown. Then, the operator opens and lifts the second cover 132 to remove the locked second product and the first product, as shown. Figure 8 As shown.

[0071] Then, new first and second products are added again, and the above process is repeated to continuously add locks to the second and first products.

[0072] Understandably, the positioning device 100 of this application is not limited to positioning and locking the second product and the first product. It can also be used to position only one or more products to achieve other processing of the products.

[0073] In summary, the positioning device 100 of this utility model sets the cover plate assembly 130 as a double cover plate structure, that is, it provides a first cover plate 131 and a second cover plate 132 that are pivotally connected to each other. The second cover plate 132 can pivot relative to the first cover plate 131 to close or open. The first cover plate 131 has a through hole 1311 that can be sleeved on the support platform 111 of the bottom mold assembly 110. The second cover plate 132 has multiple operating holes 1321 that penetrate through it. At the same time, a drive assembly 120 connected to the cover plate assembly 130 is provided. In this way, after the product is placed on the support platform 111, the second cover plate 132 is pivoted first to close it on the first cover plate 131. The drive assembly 120 then drives the cover plate assembly 130 to descend relative to the bottom mold assembly 110, thereby enabling the second cover plate 132 to press and position the product on the support platform 111. During this process, the cover plate assembly 130 descends vertically and presses against the product, thus ensuring that the downward pressure applied to the product is balanced, effectively preventing product tilting. Furthermore, the downward force and speed of the cover plate assembly 130 are controllable, resulting in a significant improvement in the product processing yield. Based on this, the disassembly rate of the positioning device 100 is correspondingly reduced, and the lifting and lowering of the cover plate assembly 130 is automatic, thereby significantly improving production efficiency, reducing the number of operators, and thus reducing costs.

[0074] The structures of other parts of the positioning device 100 involved in this utility model are all conventional structures well known to those skilled in the art, and will not be described in detail here.

[0075] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
