Description

Technical Field

[0001] The utility model relates to the field of plastic clips, in particular to an environment-friendly plastic clip structure formed by secondary injection molding. Background Art

[0002] Plastic clips are widely and diversely used in life. Due to their light weight, durability and other characteristics, they are used in various application scenarios such as document sorting and clothes hanging.

[0003] The two ends of common plastic clips in daily life can be divided into a holding end and a clamping end according to their use functions. At the same time, the common holding end is generally designed in a long strip or tapered shape. Due to the gradually decreasing width of the tapered design at the holding end, the pressure distribution between the fingers of the user will become uneven when holding. The narrower end will cause the fingers to bear greater pressure, resulting in discomfort during use. And for the long strip design, due to the different hand sizes and shapes of different people, the long strip holding end may not be able to well adapt to the hand structures of all users. For users with larger hand shapes or thicker fingers, their fingers may not be able to comfortably hold the holding end, thus affecting the comfort and efficiency of use. Summary of the Utility Model

[0004] This application provides an environment-friendly plastic clip structure formed by secondary injection molding, which has the effect of improving the comfort of the holding end.

[0005] The technical solution adopted for the environment-friendly plastic clip structure formed by secondary injection molding provided by this application is as follows:

[0006] An environment-friendly plastic clip structure formed by secondary injection molding includes a left clip part and a right clip part, and the left clip part and the right clip part are cooperatively connected to each other; both ends of the left clip part and the right clip part are respectively a clamping end and a holding end, and the holding ends of the left clip part and the right clip part are both in a ring shape.

[0007] Through the above technical solution, the holding end is changed from a tapered shape to a ring shape, which increases the contact area when the user holds the clip without increasing much material consumption; thus evenly distributing the pressure between the fingers of the user when holding, and the larger contact area also reduces the requirements for the user's hand shape and finger thickness.

[0008] Preferably, an elastic ring is secondary injection molded in the ring of the holding end. An annular groove is formed on the elastic ring, the inner peripheral surface of the annular groove abuts against the inner side wall of the holding end, and the inner side walls on the left and right sides of the annular groove are attached to the left and right side end faces of the holding end; a plurality of L-shaped anti-slip grooves are circumferentially formed on the left and right side end faces of the holding end.

[0009] Through the above technical solution, the elastomeric ring formed by secondary injection molding provides a better holding feel. Meanwhile, the design of the L-shaped anti-slip groove enables anti-slip strips to be formed on the elastomeric ring after secondary injection molding; the anti-slip strips reduce the situation where the user exerts force during use, causing relative displacement between the elastomeric ring and the left and right end faces of the handheld end.

[0010] Preferably, a plurality of communication grooves are formed on the inner side wall of the handheld end, and both ends of the plurality of communication grooves are respectively communicated with a pair of left and right corresponding anti-slip grooves.

[0011] Through the above technical solution, the communication grooves provide a flow channel for the secondary injection molding of the elastomeric ring, and play a role in hindering the relative movement between the elastomeric ring and the inner side wall of the handheld end after the molding is completed.

[0012] Preferably, a circumferential groove is formed on the inner side wall of the handheld end, and the circumferential groove is communicated with the plurality of communication grooves.

[0013] Through the above technical solution, a circumferential strip will be formed in the circumferential groove during secondary injection molding. The circumferential strip further increases the contact area between the elastomeric ring and the inner side wall of the handheld end, thereby further enhancing the friction between the elastomeric ring and the inner side wall of the handheld end, and ultimately further preventing the relative movement between the elastomeric ring and the inner side wall of the handheld end.

[0014] Preferably, straight groove holes are respectively formed in the plurality of anti-slip grooves, and barb structures are further arranged in the plurality of straight groove holes.

[0015] Through the above technical solution, the design of the straight groove holes enables straight groove strips with barbs to be formed on the surface of the anti-slip strip during the secondary injection molding of the elastomeric ring. The straight groove strips with barbs and the straight groove holes cooperate to lock the anti-slip strip in the anti-slip groove, thereby reducing the situation where the user unconsciously buckles up the elastomeric ring to form a gap during use.

[0016] Preferably, elastic pads are respectively installed at the clamping ends of the left clamping part and the right clamping part; when there is no external force, the two elastic pads are attached to each other.

[0017] Through the above technical solution, the elasticity of the elastic pads can reduce scratches or damage to the surface of the item during the clamping process.

[0018] Preferably, both the elastomeric ring and the elastic pads are made of silicone rubber material.

[0019] Through the above technical solution, silicone rubber has excellent toughness and elasticity, and also has good performance in terms of wear resistance, moisture resistance, heat resistance and cold resistance, and is harmless to the human body.

[0020] The technical effects of the present utility model are mainly reflected in the following aspects:

[0021] 1. The utility model improves the contact area when the user holds it without increasing much material consumption by changing the handheld end from a reduced shape to a ring shape, thereby providing the comfort of the user during use;

[0022] 2. The utility model further increases the comfort of the handheld end by secondary injection molding an elastic ring on the handheld ends of the left clamping part and the right clamping part;

[0023] 3. The utility model improves the connection stability between the elastic ring and the handheld end by opening various notches on the handheld end, thereby prolonging the service life of the elastic ring. Brief Description of the Drawings

[0028] The following will be further described in detail in conjunction with the attached Figures 1-3 drawings to make the technical solutions of the present utility model easier to understand and master.

[0029] The embodiment of the present application discloses an environment-friendly plastic clip structure with secondary injection molding:

[0030] Referring to Figure 1 , an environment-friendly plastic clip structure with secondary injection molding includes a left clamping part 1 and a right clamping part 2, and the left clamping part 1 and the right clamping part 2 are connected in cooperation with each other. The two ends of the left clamping part 1 and the right clamping part 2 are respectively a clamping end 3 and a handheld end 4, and the handheld ends 4 of the left clamping part 1 and the right clamping part 2 are both in a ring shape. Changing the handheld end 4 from a reduced shape to a ring shape improves the contact area when the user holds it without increasing much material consumption; thereby evenly distributing the pressure between the fingers when the user holds it, and the larger contact area also reduces the requirements for the user's hand shape and finger thickness. A hinge seat is fixed in the middle of the left clamping part 1 and the right clamping part 2, and the two are hinged together through the hinge seat, and an elastic strip is installed to abut the clamping ends 3 of the left clamping part 1 and the right clamping part 2 against each other without external force.

[0031] Referring to Figures 2-3 , an elastic ring 5 is secondarily injection-molded within the circular ring of the handheld end 4. An annular groove 55 is formed on the elastic ring 5. The inner circumferential surface of the annular groove 55 abuts against the inner sidewall 46 of the handheld end, and the inner sidewalls on the left and right sides of the annular groove 55 are attached to the left and right end faces of the handheld end 4. A plurality of L-shaped anti-slip grooves 41 are circumferentially formed on the left and right end faces of the handheld end 4. The secondarily injection-molded elastic ring 5 provides a better holding feel. At the same time, the design of the L-shaped anti-slip grooves 41 causes anti-slip strips 51 to be formed on the elastic ring 5 after the secondary injection molding. The anti-slip strips 51 reduce the situation where the user exerts force during use, causing relative displacement between the elastic ring 5 and the left and right end faces of the handheld end 4.

[0032] Referring to Figure 3 , a plurality of communication grooves 42 are formed on the inner sidewall 46 of the handheld end. Both ends of the plurality of communication grooves 42 are respectively communicated with a pair of left and right corresponding anti-slip grooves 41. The communication grooves 42 provide a flow path for the secondary injection molding of the elastic ring 5 and form communication strips 52 after the molding is completed, which plays a role in hindering the relative movement between the elastic ring 5 and the inner sidewall 46 of the handheld end.

[0033] Referring to Figure 3 , an annular groove 43 is circumferentially formed on the inner sidewall 46 of the handheld end. The annular groove 43 is communicated with the plurality of communication grooves 42. The annular groove 43 will form an annular strip 53 during the secondary injection molding. The annular strip 53 further increases the contact area between the elastic ring 5 and the inner sidewall 46 of the handheld end, thereby further enhancing the friction between the elastic ring 5 and the inner sidewall 46 of the handheld end and ultimately further preventing the relative movement between the elastic ring 5 and the inner sidewall 46 of the handheld end.

[0034] Referring to Figure 3 , straight groove holes 44 are respectively formed in the plurality of anti-slip grooves 41, and barb structures 45 are further provided in the plurality of straight groove holes 44. The design of the straight groove holes 44 causes straight groove strips 54 with barbs to be formed on the surface of the anti-slip strips 51 during the secondary injection molding of the elastic ring 5. The straight groove strips 54 with barbs and the straight groove holes 44 cooperate to lock the anti-slip strips 51 within the anti-slip grooves 41, thereby reducing the situation where the user unconsciously buckles up the elastic ring 5 to form a gap during use.

[0035] Referring to Figure 1, elastic pads 6 are respectively installed at the clamping ends 3 of the left clamping part 1 and the right clamping part 2; when there is no external force, the two elastic pads 6 are in contact with each other. The elasticity of the elastic pads 6 can reduce the scratches or damages to the surface of the article during the clamping process. Both the elastic ring 5 and the elastic pads 6 are made of silicone rubber. Silicone rubber has excellent toughness and elasticity, and at the same time has good performance in wear resistance, moisture resistance, heat resistance and cold resistance, and is harmless to the human body. Due to the above settings, the clip has an increased service life and stability, can be used repeatedly for a long time, reduces the waste generated due to frequent replacement, and improves the environmental protection benefits.

[0036] Of course, the above are only typical examples of the present utility model. In addition, the present utility model can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present utility model.
