Description

Technical Field

[0001] This utility model relates to the technical field of chrome plating shielding products, specifically to an anti-deformation structure for chrome plating shielding products. Background Technology

[0002] When chrome plating is performed on shielding parts, uneven heating occurs due to the difference in heat conduction between the shielding parts and the chrome-plated areas. The molecular chains of the material at the opening shrink due to thermal stress, causing inward deformation at the opening, which affects the product's precision and function. Therefore, anti-deformation structures are often used to prevent inward deformation at the opening.

[0003] In existing technologies, shielding components are often not designed with anti-deformation structures, which can easily lead to uneven heating of the injection molded material, resulting in deformation at the opening. Alternatively, simple methods such as tape or clamps are used to prevent deformation, which not only increases production costs but also easily damages the product, thus affecting its normal use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a deformation-preventing structure for shielding chrome-plated products. It can effectively solve the problem that in the prior art, there is often no design of a deformation-preventing structure, which easily leads to uneven heating of the injection molded material, resulting in deformation at its opening. Alternatively, simple means such as tape and clamps are used to prevent deformation, which not only has high production costs but also easily damages the product, thus affecting its normal use.

[0005] The technical solution adopted by this utility model is: a deformation-preventing structure for shielding chrome-plated products, including a base and an open strip, the base and the open strip being integrally formed, a connecting block being fixedly installed at the end of the open strip away from the base, a rib being fixedly installed at the inner edge of the connecting block, both ends of the rib being connected to the connecting block, a groove being provided at the end of the open strip away from the base, a retaining frame being provided at the end of the open strip near the groove, and limiting frames being fixedly installed at both ends of the retaining frame away from the center line, the diameter of the limiting frame being larger than the diameter of the retaining frame.

[0006] Preferably, the base is fixedly installed with a first buckle and a second buckle on the extended portion near the opening strip, and there are multiple identical first buckles and second buckles distributed in a ring around the base.

[0007] With the above technical solution, the buckles 1 and 2 are arranged in a ring on the base, so that the shielding part can form a multi-point snap-fit ​​with the opening edge of the injection molded part when in use, which can facilitate its quick connection with the injection molded product.

[0008] Preferably, the base and the opening strip together form a "U" shaped structure, and the end of the second buckle away from the base has a slot.

[0009] The above technical solution forms a semi-enclosed support frame through the "U"-shaped base and the opening strip. The slot, in conjunction with the second buckle, allows for insertion into the slot during use, facilitating quick positioning during connection.

[0010] Preferably, the rib is connected to the open strip via a connecting block, and a protrusion is fixedly installed at the end of the open strip away from the base.

[0011] Through the above technical solution, the ribs serve as temporary supports during the chrome plating process, effectively counteracting the deformation force caused by the inward shrinkage of the opening. Since both ends of the ribs are connected to the connecting blocks, when the opening of the injection molded part is subjected to inward extrusion force, the ribs can distribute the stress to the connecting blocks and the opening strip. After electroplating is completed, the temporary support structure can be removed by cutting along the connection between the ribs and the connecting blocks, leaving no excess material.

[0012] Preferably, the opening strip is adapted to the card frame and the limiting frame through the first groove, the card frame and the limiting frame are an integral structure, and the limiting frame has two grooves at both ends away from the center line.

[0013] Through the above technical solution, by cooperating with the groove and the card frame and the limiting frame, the card frame can be placed in the groove, and then the limiting frame can fit into the opening strip, which can provide secondary support for the opening strip, further improve its resistance to deformation, and also make it easy to remove and reuse.

[0014] Preferably, there are two identical grooves, card frames, and limiting frames, and the two grooves, card frames, and limiting frames are symmetrically distributed about the center line of the opening strip.

[0015] The above technical solution, through the design of two grooves, a retaining frame, and a limiting frame, can provide support from both ends of the opening strip, thus preventing deformation at the end furthest from the opening strip and affecting normal use.

[0016] Compared with the prior art, this utility model provides a structure to prevent deformation of chrome-plated products, which has the following beneficial effects:

[0017] 1. The anti-deformation structure of the shielding chrome-plated product has ribs that serve as temporary supports during the chrome plating process. These ribs can effectively counteract the deformation force caused by the inward shrinkage of the opening. Since both ends of the ribs are connected to the connecting blocks, when the opening of the injection molded part is subjected to inward extrusion force, the ribs can distribute the stress to the connecting blocks and the opening strip. After electroplating is completed, the temporary support structure can be removed by cutting along the connection between the ribs and the connecting blocks, leaving no excess material.

[0018] 2. The anti-deformation structure of the chrome-plated shielding product, through the cooperation of the groove, the card frame and the limiting frame, allows the card frame to be placed in the groove, and then the limiting frame to fit the opening strip, which can provide secondary support for the opening strip, further improving its anti-deformation ability, and also making it easy to remove and reuse.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figure 1-6As shown, the present invention provides a structure for preventing deformation of chrome-plated products, including a base 1 and an open strip 5. The base 1 and the open strip 5 are integrally formed. A connecting block 7 is fixedly installed at the end of the open strip 5 away from the base 1. A rib 8 is fixedly installed at the inner edge of the connecting block 7. Both ends of the rib 8 are connected to the connecting block 7. A groove 9 is provided at the end of the open strip 5 away from the base 1. A retaining frame 10 is provided at the end of the open strip 5 near the groove 9. Limiting frames 11 are fixedly installed at both ends of the retaining frame 10 away from the center line. The diameter of the limiting frame 11 is larger than the diameter of the retaining frame 10.

[0028] Specifically, the base 1 is fixedly installed with buckles 1 2 and 2 3 near the extension of the opening strip 5. There are multiple buckles 1 2 and 2 3, which are arranged in a ring around the base 1. The advantage is that the ring arrangement of buckles 1 2 and 2 3 on the base 1 allows the shielding part to form a multi-point engagement with the opening edge of the injection molded part during use, which facilitates quick connection with the injection molded product.

[0029] Specifically, the base 1 and the opening strip 5 together form a "U" shaped structure. The end of the buckle 2 3 away from the base 1 has a slot 4. The advantage is that the base 1 and the opening strip 5 form a semi-enclosed support frame through the "U" shaped structure. Furthermore, the buckle 2 3, in conjunction with the slot 4, allows the buckle to be inserted into the slot 4 during use, which facilitates quick positioning during connection.

[0030] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0031] Specifically, the rib 8 is connected to the opening strip 5 via the connecting block 7. A protrusion 6 is fixedly installed at the end of the opening strip 5 away from the base 1. The advantage is that the rib 8 acts as a temporary support during the chrome plating process, which can effectively counteract the deformation caused by the inward shrinkage of the opening. Since both ends of the rib 8 are connected to the connecting block 7, when the opening of the injection molded part is subjected to inward extrusion force, the rib 8 can distribute the stress to the connecting block 7 and the opening strip 5. After the electroplating is completed, the temporary support structure can be removed by cutting along the connection between the rib 8 and the connecting block 7, leaving no excess material.

[0032] Specifically, the opening strip 5 is adapted to the card frame 10 and the limiting frame 11 through the groove 1 9. The card frame 10 and the limiting frame 11 are an integral structure. The two ends of the limiting frame 11 away from the center line are provided with the groove 2 12. The advantage is that, through the cooperation of the groove 1 9 with the card frame 10 and the limiting frame 11, the card frame 10 can be placed in the groove 1 9, and then the limiting frame 11 can fit against the opening strip 5, which can provide secondary support for the opening strip 5 and further improve its resistance to deformation.

[0033] Specifically, there are two identical grooves 9, clip frames 10 and limiting frames 11. The two grooves 9, clip frames 10 and limiting frames 11 are symmetrically distributed about the center line of the opening strip 5. The advantage is that the design of the two grooves 9, clip frames 10 and limiting frames 11 can support the opening strip 5 from both ends, which can prevent the end away from the opening strip 5 from deforming and thus affecting normal use.

[0034] Working principle: During use, the buckles 1 (2) and 2 (3) are arranged in a ring on the base 1, allowing the shielding part to engage with the opening edge of the injection molded part at multiple points, facilitating quick connection with the injection molded product. The "U"-shaped base 1 and the opening strip 5 form a semi-enclosed support frame, and the buckle 2 (3) allows the part to be inserted into the slot 4 during use, facilitating quick positioning during connection. The rib 8 acts as a temporary support during the chrome plating process, effectively counteracting deformation caused by the inward shrinkage of the opening. Since both ends of the rib 8 are connected to the connecting block 7, when the opening of the injection molded part is subjected to inward extrusion... Under pressure, the rib 8 can distribute the stress to the connecting block 7 and the opening strip 5. After electroplating is completed, it can be cut along the connection between the rib 8 and the connecting block 7 to remove the temporary support structure without leaving any excess material. Through the cooperation of the groove 9 with the frame 10 and the limiting frame 11, the frame 10 can be placed in the groove 9. Then, the limiting frame 11 fits against the opening strip 5, which can provide secondary support for the opening strip 5 and further improve its resistance to deformation. Through the design of the two grooves 9, the frame 10 and the limiting frame 11, the opening strip 5 can be supported from both ends, which can prevent the end away from the opening strip 5 from deforming and thus affecting normal use.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
