Description

Technical Field

[0001] This utility model relates to the field of mechanical parts cleaning technology, and in particular to a carrier. Background Technology

[0002] Before and after micro-hole etching or machining, products often need to be cleaned to remove dirt adhering to the surface and prevent contaminants from affecting subsequent processing and the product surface. In related technologies, products are typically placed on a carrier for cleaning. However, existing carriers are generally only suitable for a single product specification. For products with rapid product updates, due to the differences between new and old products, old carriers cannot be reused, resulting in low carrier reuse rates. Utility Model Content

[0003] This invention provides a vehicle to solve at least one of the problems mentioned in the background art.

[0004] The carrier according to the embodiments of this application includes a body, a snap-fit ​​component, and a first limiting component. The body includes a longitudinal beam and a plurality of crossbeams connected to the longitudinal beam and arranged at intervals. The snap-fit ​​component is detachably connected to any two adjacent crossbeams and includes a mounting base and a support component connected to the mounting base. The mounting base includes two first snap-fit ​​portions disposed opposite each other. Each first snap-fit ​​portion is provided with a first mounting groove. The two first snap-fit ​​portions are snapped onto the two adjacent crossbeams through the first mounting grooves. The two first limiting components are detachably connected to the two first snap-fit ​​portions respectively to restrict the corresponding first snap-fit ​​portions from detaching from the crossbeams.

[0005] In the carrier of this application embodiment, the snap-fit ​​component is fixed to the crossbeam by a first limiting member. Under sufficient external force, the first limiting member can quickly snap into the first snap-fit ​​portion on the mounting base, thus fixing the snap-fit ​​component stably to the crossbeam without any other fixing operations. The first limiting member and the first snap-fit ​​portion of the snap-fit ​​component are detachably snapped together. When the snap-fit ​​component needs to be replaced, only the first limiting member needs to be removed and installed. In this way, the removal and installation of the snap-fit ​​component are very fast, effectively improving the replacement efficiency of the snap-fit ​​component. At the same time, when the product changes, there is no need to change the carrier. Only the distance of the snap-fit ​​component on the crossbeam needs to be quickly adjusted as needed to adapt it to the product requirements, and the carrier has good versatility.

[0006] In some embodiments, each of the two first snap-fit ​​portions includes two first elastic arms disposed opposite to each other, a first mounting groove is formed between the two first elastic arms, and a first limiting groove communicating with the first mounting groove is formed on the side of each first elastic arm, and the bottom surface of the first limiting groove abuts against the bottom of the crossbeam.

[0007] In the above embodiment, the first limiting groove and the first mounting groove are spatially connected to prevent the snap-fit ​​from coming off in the vertical direction. The plane of the first limiting groove in the vertical direction contacts the two vertical sides of the crossbeam, which to a certain extent restricts the swing of the snap-fit ​​in the length direction of the mounting base, so that the snap-fit ​​is further securely installed on the crossbeam.

[0008] In some embodiments, each of the first elastic arms has a first snap-fit ​​groove formed at the end away from the first limiting groove. The first snap-fit ​​groove has a first opening that penetrates the first elastic arm, and the first limiting member is snapped into the first snap-fit ​​groove through the first opening.

[0009] In the above embodiment, without the application of external force, the first limiting member cannot leave the first locking groove in the vertical direction, which to a certain extent restricts the degree of freedom of the first limiting member and provides a guarantee for ensuring the absolute static position of the locking member relative to the crossbeam.

[0010] In some embodiments, the first limiting member includes a first connecting post and first limiting blocks respectively connected to opposite ends of the first connecting post. The first connecting post passes through the first mounting grooves of the two first elastic arms, and the two first limiting blocks respectively abut against the outer surfaces of the two first elastic arms.

[0011] In the above embodiment, the side of the first limiting block facing the first elastic arm abuts against the outer side of the first elastic arm, and the first limiting member cannot move in the horizontal direction. Thus, under the action of the first limiting block and the first connecting column, the first elastic arm as a whole generates and maintains a certain rebound force, which is beneficial to further stabilize the snap-fit ​​member on the crossbeam.

[0012] In some embodiments, the first snap-fit ​​groove includes a first engaging section and a first inserting section connected to the first engaging section, the first limiting member snaps into the first engaging section, the first inserting section has the first opening, and the width of the first inserting section decreases along the first opening toward the first engaging section.

[0013] In the above embodiment, the first locking section forms a guide slope. When the contact point between the first limiting member and the first locking section is located at the connection between the first locking section and the first engaging section, under the continuous action of external force, the first limiting member slides from the first locking section into the first engaging section. The first locking section is no longer under force and thus returns to its original state. In this way, the first limiting member is completely inserted into the first engaging section of the first locking groove, thereby fixing the mounting base.

[0014] In some embodiments, the snap-fit ​​component further includes two support members, each support member including two opposing second snap-fit ​​portions, each second snap-fit ​​portion having a second mounting groove, the two second snap-fit ​​portions being snapped onto the mounting base through the second mounting groove, the carrier further including a second limiting member, the second limiting member being detachably snapped onto the two second snap-fit ​​portions to prevent the two second snap-fit ​​portions from disengaging from the mounting base.

[0015] In the above embodiment, the second limiting member moves and engages with the second engaging part under sufficient external force, thereby fixing the support member without the need for other fixing operations. The engagement of the second limiting member is very convenient and helps to improve the replacement efficiency of the support member.

[0016] In some embodiments, each of the two second snap-fit ​​portions includes two opposing second elastic arms, a second mounting groove is formed between the two second elastic arms, and a second limiting groove communicating with the second mounting groove is formed on the side of each second elastic arm, the bottom surface of the second limiting groove abutting against the bottom of the mounting base.

[0017] In the above embodiment, by opening a very simple second groove in the second mounting slot, the space occupied by the second mounting slot is fully utilized, and the support can be further fixed without other limiting structures. This is very convenient for manufacturing and helps to reduce the manufacturing cost of the support.

[0018] In some embodiments, a second snap-fit ​​groove is formed at the end of the second elastic arm away from the second limiting groove. The second snap-fit ​​groove has a second opening that penetrates the second elastic arm, and the second limiting member is snapped into the second snap-fit ​​groove through the second opening.

[0019] In the above embodiments, by reasonably designing the width of the second opening, the second limiting member can smoothly enter the second snap-fit ​​groove, and the snap-fit ​​groove can achieve snap-fit ​​with the second limiting member with a shorter length. While ensuring the function of the second snap-fit ​​groove, the length of the second snap-fit ​​groove can be reduced, further reducing the manufacturing cost of the support member and improving the economic practicality of the snap-fit ​​member.

[0020] In some embodiments, the second limiting member includes a second connecting post and second limiting blocks respectively connected to opposite ends of the second connecting post. The second connecting post passes through the second mounting grooves of the two second elastic arms, and the two second limiting blocks abut against the outer surfaces of the two second elastic arms respectively.

[0021] In the above embodiment, the abutment of the second limiting block against the second elastic arm ensures a firm connection between the support member and the mounting base. Under normal operating conditions, the support member cannot move relative to the mounting base. Thus, by rationally designing the length of the connecting column, sufficient rebound force can be generated by the second elastic arm to secure the support member to the mounting base. The structure of the second limiting member is very simple, which can reduce the overall manufacturing cost.

[0022] In some embodiments, the second snap-fit ​​groove includes a second engaging section and a second inserting section connected to the second engaging section, the second limiting member snaps into the second engaging section, the second inserting section has the second opening, and the width of the second inserting section decreases along the second opening toward the second engaging section.

[0023] In the above embodiment, the gradually decreasing width of the second locking section ensures that the width of the second locking section at the contact position with the second engaging section is much smaller than the diameter of the second connecting post. This restricts the second limiting member from moving out of the second engaging section under normal working conditions, ensuring that the second limiting member always enables the second elastic arm to generate the required rebound force to fix the support member on the mounting base.

[0032] Please see Figure 1 combine Figure 2 , Figure 1 This is a schematic diagram of the structure of the vehicle 100 according to an embodiment of the present invention. Figure 2This is a schematic diagram of the snap-fit ​​component 20 according to an embodiment of the present utility model. The carrier 100 of this application embodiment includes a body 10, a snap-fit ​​component 20, and a first limiting component 30. The body 10 includes a longitudinal beam 11 and a plurality of crossbeams 12 connected to the longitudinal beam 11, with the plurality of crossbeams 12 arranged at intervals. The snap-fit ​​component 20 includes a mounting base 21 and a support component 22 connected to the mounting base 21. The mounting base 21 includes two first snap-fit ​​portions 211 arranged opposite to each other. Each first snap-fit ​​portion 211 is provided with a first mounting groove 212. The two first snap-fit ​​portions 211 are snapped onto any two adjacent crossbeams 12 through the first mounting groove 212. The first limiting component 30 is detachably snapped onto the first snap-fit ​​portion 211 to limit the first snap-fit ​​portion 211 from falling off the crossbeam 12. When there are multiple snap-fit ​​components 20, each snap-fit ​​component 20 is snapped onto the corresponding two adjacent crossbeams 12 as needed. If there is interference when two sets of snap-fit ​​components 20 are snapped together, the two sets of crossbeams 12 snapped together by the two sets of snap-fit ​​components 20 can be spaced apart by one crossbeam 12 as needed.

[0033] In the carrier 100 of this embodiment, the snap-fit ​​component 20 is fixed to the crossbeam 12 by the first limiting component 30. Under sufficient external force, the first limiting component 30 can quickly snap into the first snap-fit ​​portion 211 on the mounting base 21, thus fixing the snap-fit ​​component 20 stably to the crossbeam 12 without any other fixing operations. The first limiting component 30 and the first snap-fit ​​portion 211 of the snap-fit ​​component 20 are detachably snapped together. When the snap-fit ​​component 20 needs to be replaced, only the first limiting component 30 needs to be removed and installed. In this way, the removal and installation of the snap-fit ​​component 20 are very fast, effectively improving the replacement efficiency of the snap-fit ​​component 20. At the same time, when the product changes, there is no need to replace the carrier 100. Only the distance of the snap-fit ​​component 20 on the crossbeam 12 needs to be quickly adjusted to adapt to the product requirements. The carrier 100 has good versatility.

[0034] Specifically, the carrier 100 is a device used to carry, fix, and position products. As a basic platform, the carrier 100 bears the weight of products placed on it and ensures that each product is in a precise and fixed position when placed on the carrier 100, preventing damage to the product surface due to collisions or scratches. The body 10 is the basic main structure of the carrier 100, directly carrying the products and serving as the mounting platform for the snap-fit ​​component 20, providing structural rigidity and stability to the entire carrier 100.

[0035] The longitudinal beam 11 of the body 10 is the main supporting structure of the body 10. The surface contour of the transverse beam 12 of the body 10 matches the connection part of the snap-fit ​​20 to provide initial positioning and support for the snap-fit ​​20. The snap-fit ​​20 is a structure installed on the body 10 of the carrier 100 for lifting and placing the product, keeping it at a certain height from the body 10. For example, multiple snap-fits 20 can be provided according to the shape and size of the product so that they can cooperate with each other to place the product stably.

[0036] The first limiting member 30 is used to restrict the movement and rotational freedom of the snap-fit ​​member 20 in the horizontal plane. The first limiting member 30 rigidly limits its relative movement stroke with the snap-fit ​​member 20 through mechanical contact. When the first limiting member 30 and the first snap-fit ​​part 211 are fully engaged, the two no longer move relative to each other. The mounting base 21 of the snap-fit ​​member 20 can be firmly connected with the crossbeam 12 to ensure that the snap-fit ​​member 20 is in the correct position and orientation and to transmit the force borne by the snap-fit ​​member 20 to the body 10.

[0037] The first snap-fit ​​portion 211 is a key part on the mounting base 21 that is directly responsible for engaging and clamping the crossbeam 12. The two first snap-fit ​​portions 211 are arranged facing each other, which can clamp the mounting base 21 from both sides and restrict the movement of the snap-fit ​​member 20 relative to the mounting base 21. The first snap-fit ​​portion 211 has a certain elasticity. For example, the first snap-fit ​​portion 211 can be made of urethane material, allowing the crossbeam 12 to be snapped into the first mounting groove 212 of the snap-fit ​​member 20, and achieving tight fixation by utilizing the rebound force of the material.

[0038] When the snap-fit ​​component 20 needs to be replaced due to structural damage, the snap-fit ​​component 20 can be released by applying an external force to the first limiting member 30 to remove it from the first snap-fit ​​part 211. The snap-fit ​​component 20 can then be easily removed from the crossbeam 12. When installing the snap-fit ​​component 20 in a new position, a certain force is applied to the first limiting member 30 to snap it into the first snap-fit ​​part 211, thus securing the snap-fit ​​component 20 to the crossbeam 12. The disassembly and installation of the snap-fit ​​component 20 are very convenient, which helps to reduce the time required to replace the snap-fit ​​component 20 and improve the replacement efficiency of the snap-fit ​​component 20. At the same time, when the product changes, there is no need to change the carrier 100. It is only necessary to quickly adjust the distance of the snap-fit ​​component 20 on the crossbeam 12 as needed to adapt it to the product requirements. The carrier 100 has good versatility.

[0039] Please refer to the diagram again. Figure 2 and Figure 3 , Figure 3This is a schematic diagram of the structure of the mounting base 21 according to an embodiment of the present invention. In some embodiments, the first snap-fit ​​portion 211 includes two first elastic arms 211a disposed opposite to each other, a first mounting groove 212 is formed between the two first elastic arms 211a, and a first limiting groove 211a1 communicating with the first mounting groove 212 is formed on the side of each first elastic arm 211a, and the bottom surface of the first limiting groove 211a1 abuts against the bottom of the crossbeam 12.

[0040] In the above embodiment, the first limiting groove 211a1 and the first mounting groove 212 are spatially connected to prevent the snap-fit ​​20 from coming off in the vertical direction. The plane of the first limiting groove 211a1 in the vertical direction contacts the two vertical sides of the crossbeam 12, which to a certain extent restricts the swing of the snap-fit ​​20 in the length direction of the mounting base 21, so that the snap-fit ​​20 is further securely installed on the crossbeam 12.

[0041] Specifically, the first elastic arm 211a is a cantilever beam structure with a certain elasticity and deformation capacity, which can bend under external force and return to its original shape after the external force is removed. The first limiting groove 211a1 is a groove machined on the side of the first elastic arm 211a, which is spatially connected with the first mounting groove 212 to jointly prevent the snap-fit ​​20 from coming off in the vertical direction. The side of the first limiting groove 211a1 forms a mechanical interlock in the horizontal direction by contacting the surface of the mounting base 21, further restricting the movement of the snap-fit ​​20.

[0042] The two first elastic arms 211a have a certain deformation capacity. When the snap-fit ​​20 is installed on the crossbeam 12, the movable ends of the two first elastic arms 211a can be pulled apart by a certain distance, so that the distance between them in the length direction of the mounting base 21 is greater than the width of the crossbeam 12. The snap-fit ​​20 moves from top to bottom in the vertical direction, so that the first mounting groove 212 formed between the first elastic arms 211a is combined with the crossbeam 12, so that the lower surface of the mounting base 21 and the two opposing surfaces of the first elastic arms 211a are in contact with the upper surface of the crossbeam 12 and the two vertical sides of the crossbeam 12 respectively.

[0043] Two opposing first limiting grooves 211a1 are formed on opposite sides of the first elastic arm 211a. After the lower surface of the mounting base 21 contacts the upper surface of the crossbeam 12, the two first elastic arms 211a return to their original shape, and the crossbeam 12 fits into the two first limiting grooves 211a1. The bottom surfaces of the two first limiting grooves 211a1 of the crossbeam 12 contact the lower surface of the crossbeam 12. Thus, under the combined action of the first limiting groove and the first mounting groove 212, the snap-fit ​​member 20 cannot move in the vertical direction relative to the crossbeam 12, providing further support for the stable fixation of the snap-fit ​​member 20.

[0044] Please refer to the following: Figure 2 and Figure 3 In some embodiments, a first snap-fit ​​groove 211a2 is formed at the free end of the first elastic arm 211a. The first snap-fit ​​groove 211a2 has a first opening 211a3 that penetrates the free end face of the first elastic arm 211a. The first limiting member 30 is snapped into the first snap-fit ​​groove 211a2 through the first opening 211a3.

[0045] In the above embodiment, without the application of external force, the first limiting member 30 cannot leave the first locking groove 211a2 in the vertical direction, which to a certain extent restricts the degree of freedom of the first limiting member 30, and provides a guarantee for the first limiting member 30 to achieve absolute stillness of the overall position of the locking member 20 relative to the crossbeam 12.

[0046] Specifically, the free end of the first elastic arm 211a is the end of the first elastic arm 211a that is unrestrained and can move freely. The first locking groove 211a2 is a groove formed on the free end for engaging with the first limiting member 30. The first opening 211a3 on the free end of the first elastic arm 211a makes the first locking groove 211a2 a non-closed structure, allowing the first limiting member 30 to enter the first locking groove 211a2.

[0047] The first engaging groove 211a2 at the free end of the first elastic arm 211a matches the first limiting member 30. Under the action of external force, both ends of the first limiting member 30 enter the first engaging groove 211a2 through the first opening 211a3 of the first elastic arm 211a and are tightly engaged with the first engaging groove 211a2. The shape of the first engaging groove 211a2 ensures that the first limiting member 30 is tightly engaged with it after entering the first engaging groove 211a2, thereby achieving a relatively static relative position between the first engaging groove 211a2 and the first limiting member 30. The free end of the first elastic arm 211a provides the main elastic force, the first engaging groove 211a2 at the free end achieves engagement with the first limiting member 30, and the first opening 211a3 on the free end face ensures that the first limiting member 30 smoothly enters and leaves the first engaging groove 211a2. The structure of each component is clear, the function is well-defined, and the fixing method of the engaging member 20 on the crossbeam 12 is very intuitive.

[0048] Please see Figure 3 and Figure 4 , Figure 4 This is a schematic diagram of the structure of the first limiting member 30 according to an embodiment of the present invention. In some embodiments, the first limiting member 30 includes a first connecting post 31 and first limiting blocks 32 respectively connected to both ends of the first connecting post 31. The first connecting post 31 passes through the first mounting grooves 212 of the two first elastic arms 211a, and the two first limiting blocks 32 abut against the outer surfaces of the two first elastic arms 211a respectively.

[0049] In the above embodiment, the side of the first limiting block 32 facing the first elastic arm 211a abuts against the outer side of the first elastic arm 211a, and the first limiting member 30 cannot move in the horizontal direction. Thus, under the action of the first limiting block 32 and the first connecting post 31, the first elastic arm 211a as a whole generates and maintains a certain rebound force, which is beneficial to further stabilize the snap-fit ​​member 20 on the crossbeam 12.

[0050] Specifically, the first connecting post 31 is the core connecting and supporting structure of the first limiting member 30. For example, the first connecting post 31 can be a cylinder used to connect the limiting blocks at both ends and determine the distance between the two first limiting blocks 32. The first limiting blocks 32 are two block-shaped structures respectively fixed at both ends of the first connecting post 31. For example, the second limiting block 42 can be a circular platform with a certain thickness. The second limiting block 42 is a component that directly performs the limiting function. By contacting the surfaces of the two first elastic arms 211a, the first elastic arms 211a clamp the crossbeam 12 and thus fix the mounting base 21 on the crossbeam 12.

[0051] Under external force, the first limiting member 30 engages with the first locking groove 211a2. The two ends of the first connecting post 31 contact the groove wall of the first locking groove 211a2. The circular end faces of the two ends of the first connecting post 31 are on the same vertical plane as the outer side of the first elastic arm 211a. The circular end faces of the two ends of the first connecting post 31 are combined with the first limiting block 32 to form an integral first limiting member 30. The size of the first limiting block 32 is larger than the maximum groove width of the first locking groove 211a2. The first limiting block 32 smoothly abuts against the side of the first elastic arm 211a. The first limiting member 30 and the first locking groove 211a2 are mechanically interlocked, requiring no additional power, with a low risk of failure, which helps to improve the overall connection stability of the locking member 20.

[0052] Please refer to the following: Figure 3 In some embodiments, the first snap-fit ​​groove 211a2 includes a first snap-fit ​​section 211a22 and a first snap-in section 211a21 connected to the first snap-fit ​​section 211a22. The first limiting member 30 snaps into the first snap-fit ​​section 211a22. The first snap-in section 211a21 has a first opening 211a3. The width of the first snap-in section 211a21 tends to decrease along the direction from the first opening 211a3 toward the first snap-fit ​​section 211a22.

[0053] In the above embodiment, the first locking segment 211a21 forms a guide slope. When the contact point between the first limiting member 30 and the first locking segment 211a21 is located at the connection between the first locking segment 211a21 and the first engaging segment 211a22, under the continuous action of external force, the first limiting member 30 slides from the first locking segment 211a21 into the first engaging segment 211a22. The first locking segment 211a21 returns to its original state and is no longer under force. In this way, the first limiting member 30 is completely inserted into the first engaging segment 211a22 of the first locking groove 211a2, thereby fixing the mounting base 21.

[0054] Specifically, the width of the first opening 211a3 is greater than the diameter of the first connecting post 31, ensuring that the first limiting member 30 can smoothly enter the first locking section 211a21 through the first opening 211a3. The width of the first locking section 211a21 gradually decreases along the direction from the first opening 211a3 toward the first engaging section 211a22. Because the first locking section 211a21 has a certain elasticity, when the first limiting member 30 moves toward the first engaging section 211a22 under the action of external force, the first locking section 211a21 undergoes elastic deformation. The first locking section 211a21 is always in contact with the first limiting member 30. The shape of the first engaging section 211a22 matches the shape of the first connecting post 31. The width of the first locking section 211a21 formed at the contact position between the first locking section 211a21 and the first limiting member 30 always matches the diameter of the first connecting post 31.

[0055] The gradually decreasing width of the first latching section 211a21 towards the first engaging section 211a22 causes the first latching section 211a21 to form a guiding slope. When the first limiting member 30 pushes towards the first elastic arm 211a, the first connecting post 31 will contact the guiding slope of the first engaging groove 211a2, i.e., the first latching section 211a21. The first latching section 211a21 is located at the edge of the first engaging part 211. Under the continued applied pushing force, the first latching section 211a21 will decompose the positive pushing force into a component force that causes the first elastic arm 211a to bend outward to make room. As a result, the first elastic arm 211a undergoes elastic deformation and opens outward.

[0056] When the first connecting post 31 of the first limiting member 30 passes the first locking section 211a21, the deformation force applied to the first elastic arm 211a is released instantly. The first elastic arm 211a quickly rebounds to its original position due to its own elasticity. At this time, the shape of the first limiting member 30 is fully matched with the first locking groove 211a2. Since the first opening 211a3 of the first locking groove 211a2 is away from the assembly direction, the first limiting member 30 cannot move out of the first locking groove 211a2 under normal working conditions. The movement of the first limiting member 30 is restricted. The inner wall of the first locking groove 211a2 tightly abuts against the first limiting member 30 to prevent it from falling out, ensuring the clamping effect of the first limiting member 30 on the two first elastic arms 211a, thereby ensuring that the relative position of the locking member 20 and the crossbeam 12 remains fixed.

[0057] Please see Figure 1 , Figure 2 and Figure 5 , Figure 5 This is a schematic diagram of the structure of the support member 22 according to an embodiment of the present invention. In some embodiments, the snap-fit ​​member 20 includes two support members 22, and the support member 22 includes two second snap-fit ​​portions 221 disposed opposite to each other. Each second snap-fit ​​portion 221 is provided with a second mounting groove 222. The second snap-fit ​​portion 221 is snapped onto the mounting base 21 through the second mounting groove 222. The carrier 100 also includes a second limiting member 40, which is detachably snapped onto the second snap-fit ​​portion 221 to prevent the second snap-fit ​​portion 221 from falling off the mounting base 21.

[0058] In the above embodiment, the second limiting member 40 moves and engages with the second engaging part 221 under sufficient external force, thereby fixing the support member 22 without the need for other fixing operations. The engagement of the second limiting member 40 is very convenient and helps to improve the replacement efficiency of the support member 22.

[0059] Specifically, the support member 22 is mounted on the mounting base 21 via the second mounting groove 222 of the second snap-fit ​​portion 221. The highest plane of the second mounting groove 222 contacts the upper surface of the mounting base 21, thereby restricting one degree of freedom of the support member 22 in the vertical direction. The second limiting member 40 and the second snap-fit ​​portion 221 are detachably snapped together. When the second limiting member 40 is snapped into the second snap-fit ​​portion 221, the second snap-fit ​​portion 221 abuts against the two vertical planes of the mounting base 21, generating a clamping force on the two vertical planes of the mounting base 21. This clamping force is sufficient to ensure that the support member 22 will not move relative to the mounting base 21 during the operation of the carrier 100, thereby fixing the support member 22 to the mounting base 21.

[0060] For example, the surface shape of the support member 22 can be matched with the product. Different product shapes correspond to different support members 22. Thus, when dealing with products of different shapes and sizes, only the support member 22 needs to be replaced individually, without having to replace or redesign the entire snap-fit ​​member 20, which greatly reduces the manufacturing cost of the snap-fit ​​member 20. The product is placed on the top surface of the support member 22, the mounting base 21 is fixed to the crossbeam 12, and the support member 22 is fixed to the mounting base 21. The position of the support member 22 relative to the crossbeam 12 is basically fixed, thereby ensuring that the relative position of the products is basically fixed during the operation of the carrier 100, ensuring the correct relative position between the products, and providing a guarantee for the processing quality of the products.

[0061] Please see Figure 5 In some embodiments, the second snap-fit ​​portion 221 includes two second elastic arms 221a disposed opposite to each other, a second mounting groove 222 is formed between the two second elastic arms 221a, and a second limiting groove 221a1 communicating with the second mounting groove 222 is formed on the side of each second elastic arm 221a, and the bottom surface of the second limiting groove 221a1 abuts against the bottom of the mounting base 21.

[0062] In the above embodiment, by opening a very simple second limiting groove 221a1 in the second mounting groove 222, the space occupied by the second mounting groove 222 is fully utilized, and the support member 22 can be further fixed without other limiting structures. This is very convenient for manufacturing and helps to reduce the manufacturing cost of the support member 22.

[0063] Specifically, the second elastic arm 221a has a certain elasticity. When the support member 22 is installed onto the mounting base 21, a certain external force is applied to make the distance between the two second elastic arms 221a greater than the thickness of the mounting base 21. The two opposing vertical surfaces of the second snap-fit ​​part 221 begin to contact the two vertical surfaces of the mounting base 21. Subsequently, the bottom surface of the second limiting groove 221a1, which is connected to the second mounting groove 222, abuts against the bottom of the mounting base 21. The freedom of the support member 22 in the vertical direction is completely restricted, and the support member 22 cannot move relative to the mounting base 21 in the vertical direction. This further fixes the support member 22 onto the mounting base 21 and ensures that the relative position of the support member 22 and the mounting base 21 does not change, thereby ensuring the correct position of the product in the relevant processing process.

[0064] Please refer to the following: Figure 5 In some embodiments, a second snap-fit ​​groove 221a2 is formed at the free end of the second elastic arm 221a. The second snap-fit ​​groove 221a2 has a second opening 221a3 that penetrates the free end face of the second elastic arm 221a. The second limiting member 40 is snapped into the second snap-fit ​​groove 221a2 through the second opening 221a3.

[0065] In the above embodiment, by reasonably designing the width of the second opening 221a3, the second limiting member 40 can smoothly enter the second locking groove 221a2, while the second locking groove 221a2 can achieve locking with the second limiting member 40 with a shorter length. While ensuring the function of the second locking groove 221a2, the length of the second locking groove 221a2 can be reduced, further reducing the manufacturing cost of the support member 22, which is conducive to improving the economic practicality of the locking member 20.

[0066] Specifically, the width of the second opening 221a3 ensures that the second limiting member 40 can partially enter the second locking groove 221a2 without external force. The second limiting member 40 enters the second locking groove 221a2 from the second opening 221a3. Under the continuous action of sufficient external force, the second limiting member 40 continues to move. The second locking part 221 undergoes elastic deformation due to the movement of the second limiting member 40. The deformation at the contact position between the second locking part 221 and the second limiting member 40 ensures that the second limiting member 40 can smoothly move relative to the second locking part 221 under the action of external force, thereby smoothly entering the preset locking position in the second locking groove 221a2, realizing the clamping effect of the two second elastic arms 221a on the vertical surface of the mounting base 21, thereby realizing the limiting function of the second limiting member 40.

[0067] Please see Figure 2 In some embodiments, the second limiting member 40 includes a second connecting post 41 and second limiting blocks 42 respectively connected to both ends of the second connecting post 41. The second connecting post 41 passes through the second mounting grooves 222 of the two second elastic arms 221a, and the two second limiting blocks 42 abut against the outer surfaces of the two second elastic arms 221a respectively.

[0068] In the above embodiment, the abutment of the second limiting block 42 against the second elastic arm 221a ensures a firm connection between the support member 22 and the mounting base 21. Under normal operating conditions, the support member 22 cannot move relative to the mounting base 21. Thus, by rationally designing the length of the second connecting post 41, sufficient rebound force can be generated by the second elastic arm 221a to secure the support member 22 to the mounting base 21. The structure of the second limiting member 40 is very simple, which can reduce the overall manufacturing cost.

[0069] Specifically, the second connecting post 41 is connected to the two second limiting blocks 42 at its two ends to form a second limiting member 40. For example, the second connecting post 41 and the second limiting block 42 can be integrally formed. The length of the second connecting post 41 is slightly less than the distance between the two second elastic arms 221a. When the second limiting member 40 is engaged in the second engaging groove 221a2, the second limiting blocks 42 at both ends of the second connecting post 41 abut against the two outer surfaces of the second engaging part 221. Due to the connection with the second connecting post 41, when the second limiting block 42 is fully engaged in the engaging position of the second engaging part 221, the two second engaging parts 221 will undergo a certain elastic deformation, causing the two second elastic arms 221a to move closer to each other.

[0070] At this time, due to the abutment of the two second limiting blocks 42 against the second elastic arm 221a, the deformation of the second locking part 221 cannot be restored. The force generated by the elastic deformation of the second locking part 221 acts on the contact surface between the second elastic arm 221a and the mounting base 21. This force starts from the contact position of one vertical side of the second elastic arm 221a and the mounting base 21 and points to the other vertical side of the mounting base 21. Specifically, it is manifested as the clamping action of the two second elastic arms 221a on the mounting base 21, so that the support member 22 can be stably installed on the mounting base 21.

[0071] Please see Figure 5 In some embodiments, the second snap-fit ​​groove 221a2 includes a second snap-fit ​​section 211a22 and a second snap-in section 221a21 connected to the second snap-fit ​​section 211a22. The second limiting member 40 snaps into the second snap-fit ​​section 211a22. The second snap-in section 221a21 has a second opening 221a3. The width of the second snap-in section 221a21 tends to decrease along the direction of the second opening 221a3 toward the second snap-fit ​​section 211a22.

[0072] In the above embodiment, the gradually decreasing width of the second engaging section 221a21 ensures that the width of the second engaging section 221a21 at the contact position with the second engaging section 211a22 is much smaller than the diameter of the second connecting post 41. This can prevent the second limiting member 40 from moving out of the second engaging section 211a22 under normal working conditions, and ensure that the second limiting member 40 always enables the second elastic arm 221a to generate the required rebound force to fix the support member 22 on the mounting base 21.

[0073] Specifically, the second limiting member 40 enters the second locking section 221a21 from the second opening 221a3. The width of the second locking section 221a21 gradually decreases from the second opening 221a3 toward the second locking section 211a22. When the second limiting member 40 enters the second locking section 221a21, the force acting on the second limiting member 40 gradually increases due to the gradual decrease in the width of the second locking section 221a21, and the elastic deformation of the second locking section 221a21 also gradually increases.

[0074] As the second limiting member 40 continues to move in the second engaging section 221a21, when the contact position between the second limiting member 40 and the second engaging section 221a21 moves to the connection point between the second engaging section 221a21 and the second engaging section 211a22, the second limiting member 40 is fully engaged into the second engaging section 211a22 under the continuous action of external force. The second limiting member 40 causes the second elastic arm 221a to clamp the two vertical sides of the mounting base 21, thereby fixing the support member 22. This fixing method has a simple structure, is easy to operate, has a good fixing effect, and is economical and practical.
