Description

Technical Field

[0001] This utility model relates to the field of plastic bottle technology, specifically to an adjustable handle. Background Technology

[0002] Currently, there are various types of plastic bottles on the market, such as mineral water bottles, oil bottles, and soy sauce bottles, all of which come with handles to improve portability. Based on how the handle is assembled onto the container, they are mainly divided into embedded handles, where the handle is placed in advance before blowing the bottle, and rear-mounted handles, where the handle is added later.

[0003] Embedded handles are widely used due to their relatively stable and reliable structure, adaptable to various bottle sizes from small to large, and less prone to loosening or detachment during actual use. Therefore, they are frequently used in food packaging and daily chemical products. However, the production capacity of embedded handles is limited. In the blow molding process, the handle must be accurately placed in a specific position on the mold before blow molding, increasing the complexity of the production process, resulting in a longer production cycle and lower overall production efficiency, making it difficult to meet the demands of large-scale, rapid production. Rear-mounted handles are commonly used on small-capacity bottles. Their installation relies on the handle's elastic deformation under external pressure, allowing it to smoothly insert into the bottle neck or body's latch. When the external force is removed, the handle returns to its original shape and is fixed to the bottle via the latch structure. However, because this installation method relies on the handle's elastic deformation for fixation, the handle itself has limited weight and tensile strength. If used on large-capacity bottles or bottles requiring frequent handling, the handle is prone to breakage or detachment. Therefore, it is only suitable for small-capacity bottles, with a narrower application range.

[0004] Therefore, an adjustable handle needs to be developed to overcome the shortcomings of current embedded handles and rear-mounted handles. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes an adjustable handle for later installation on plastic bottles. The process is simple, and the handle length is adjustable during installation, making installation more convenient.

[0006] The technical solution of this utility model is implemented as follows: An adjustable handle includes an upper handle and a lower handle; one end of the upper handle and the lower handle are respectively engaged with preset positions on a plastic bottle, and the other ends of the upper handle and the lower handle are movably connected; wherein, The upper handle and the lower handle are movably connected by a guide groove. The guide groove is provided along the length direction of the upper handle and can restrict the degree of freedom of the lower handle in the direction perpendicular to the length of the upper handle. A limit pin is provided on the upper handle. One end of the lower handle that mates with the upper handle is movably connected to a limiting member. When the lower handle moves along the guide groove to a preset position, the limiting member can connect with the limiting pin to restrict the degree of freedom of the lower handle in the length direction of the guide groove.

[0007] In a preferred embodiment, the guide groove includes a cavity, one end of which is open and mates with the lower handle of the handle. Limiting strips are provided on both inner walls of the cavity, and both the limiting strips and the cavity are arranged along the length of the upper handle of the handle.

[0008] In a preferred embodiment, the handle has a positioning groove, which is clearance-fitted with the limiting member, and the limiting pin is fixedly disposed in the positioning groove.

[0009] In a preferred embodiment, the positioning groove is connected to the guide groove, and the limiting plate has a limiting platform at one end near the positioning groove. When the limiting member is connected to the limiting pin, the limiting platform abuts against the limiting member.

[0010] In a preferred embodiment, the limiting member includes a locking block, which is movably connected to the lower handle of the handle, and the locking block is provided with a positioning hole, which is engaged with the limiting pin.

[0011] In a preferred embodiment, the upper handle is provided with a finger recess, which is connected to the positioning groove. The locking block is provided with a finger position and a limiting pin. When the positioning hole is inserted with the limiting pin, the limiting pin abuts against the side of the lower handle near the locking block.

[0012] In a preferred embodiment, both outer walls of the handle are provided with guide steps extending along their length, the guide steps being open at the end near the limiting member, and the guide steps slidingly engaging with the limiting strip.

[0013] In a preferred embodiment, the limiting pin includes a pin post, one end of which is fixedly connected to the upper handle of the handle, and the other end of which is connected to a cone head. The outer diameter of the cone head gradually increases towards the pin post, and the maximum outer diameter of the cone head is greater than the outer diameter of the pin post to form a reverse buckle.

[0014] In a preferred embodiment, the limiting member is rotatably connected to the lower handle via a hinge, wherein the axis of rotation of the hinge is perpendicular to the length direction of the lower handle.

[0015] In a preferred embodiment, the lower handle is provided with a plurality of weight-reducing grooves, and the lower handle is provided with reinforcing ribs, which are arranged along the length direction of the lower handle.

[0016] Compared with the prior art, the present invention has the following advantages: This invention features a guide groove on the upper handle, allowing the lower handle to move along the groove, thus adjusting the overall length of the handle. This shortens the handle's overall length during assembly onto the plastic bottle, eliminating the need for bending or deformation, and allows it to fit into the corresponding slot on the bottle. Once the handle is in the slot, the lower handle moves along the guide groove again, extending the handle's overall length until both the upper and lower handles engage with pre-set clips on the bottle. A limiting pin then connects to the limiting component, fixing the relative positions of the upper and lower handles and locking the overall length of the handle, enabling post-installation. Therefore, this invention simplifies the post-installation process on plastic bottles, effectively improving production efficiency. The adjustable handle length eliminates the need for external force to bend or deform the handle, making installation easier and significantly increasing the load-bearing capacity of the handle after installation.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0023] Reference Figures 1-15 An adjustable handle includes an upper handle 100 and a lower handle 200; one end of the upper handle 100 and the lower handle 200 are respectively engaged with preset portions on a plastic bottle 300, and the other ends of the upper handle 100 and the lower handle 200 are movably connected; wherein, The upper handle 100 and the lower handle 200 are movably connected by a guide groove 1. The guide groove 1 is arranged along the length direction of the upper handle 100 and can restrict the degree of freedom of the lower handle 200 in the direction perpendicular to the length of the upper handle 100. A limit pin 2 is provided on the upper handle 100. The lower handle 200 is movably connected to a limiting member 3 at one end that cooperates with the upper handle 100. When the lower handle 200 moves along the guide groove 1 to a preset position, the limiting member 3 can be connected to the limiting pin 2 to restrict the degree of freedom of the lower handle 200 in the length direction of the guide groove 1.

[0024] Specifically, the lower handle 200 can move along the guide groove 1, making the overall length of the handle adjustable. Before attaching the handle to the plastic bottle 300, the lower handle 200 can be moved to shorten the overall length of the handle, allowing it to pass through the pre-set slot on the plastic bottle 300 without bending or deforming. Once the handle is in the slot on the plastic bottle 300, the overall length of the handle is adjusted to extend it until it engages with the corresponding latch within the slot on the plastic bottle 300. Then, the limiting member 3 is connected to the limiting pin 2. At this point, the lower handle 200 is positioned perpendicular to the length of the upper handle 100. The degree of freedom is restricted by the guide groove 1, and the degree of freedom of the lower handle 200 in the length direction of the guide groove 1 is restricted by the limiting member 3 and the limiting pin 2. This fixes the relative position between the lower handle 200 and the upper handle 100, and locks the overall length of the handle. This keeps the handle in a state where its two ends are locked in the corresponding buckles in the slots of the plastic bottle 300, thus achieving rear-mounted installation. This effectively retains the advantages of existing rear-mounted handles, such as simple process and high production efficiency. At the same time, since no external force is required to bend or deform the handle during installation, installation is more convenient, and the load-bearing capacity is stronger, making it more widely applicable.

[0025] Preferably, the opposite ends of the upper handle 100 and the lower handle 200 each have a buckle 13 for buckling and connecting with the corresponding positions of the preset slots on the plastic bottle 300.

[0026] Furthermore, the guide groove 1 includes a cavity 101, one end of which is open and engages with the lower handle 200. Both inner walls of the cavity 101 are provided with limiting strips 102. Both the limiting strips 102 and the cavity 101 are arranged along the length of the upper handle 100, thus forming a T-groove structure. While the lower handle 200 can slide along the cavity 101, its degree of freedom in the direction perpendicular to the length of the upper handle 100 is restricted by the two limiting strips 102. This ensures that during assembly, the lower handle 200 can only move along the length of the guide groove 1, preventing it from detaching from the guide groove 1 in the direction perpendicular to the length of the upper handle 100 when subjected to force.

[0027] Furthermore, both outer walls of the lower handle 200 are provided with guide steps 12 extending along its length. The guide steps 12 are open at one end near the limiting member 3, and the guide steps 12 slide with the limiting strip 102 to form a structure in which the upper handle 100 can be fastened to the guide steps 12 by the limiting strip 102, thereby restricting the degree of freedom of the lower handle 200 in the direction perpendicular to the length of the upper handle 100.

[0028] Furthermore, a positioning groove 4 is provided on the handle 100, the positioning groove 4 is in clearance fit with the limiting member 3, and the limiting pin 2 is fixedly disposed in the positioning groove 4. When the limiting member 3 is connected to the limiting pin 2, the limiting member 3 is embedded in the positioning groove 4.

[0029] Furthermore, the positioning groove 4 is connected to the guide groove 1, and the limiting plate 102 has a limiting platform 5 at one end near the positioning groove 4. When the limiting member 3 is connected to the limiting pin 2, the limiting platform 5 abuts against the limiting member 3, which can restrict the degree of freedom of the limiting member 3 in the direction perpendicular to the axis of the limiting pin 2.

[0030] Optionally, the limiting platform 5 is the end of the limiting strip 102 near the positioning groove 4. It can be understood that the limiting platform 5 can also be a protrusion provided on the side wall of the guide groove 1 or the positioning groove 4.

[0031] Furthermore, the limiting member 3 includes a locking block 301, which is movably connected to the lower handle 200. The locking block 301 is provided with a positioning hole 302, which is engaged with the limiting pin 2. Thus, when the limiting pin 2 is inserted into the positioning hole 302, the degree of freedom of the locking block 301 in the direction perpendicular to the axis of the limiting pin 2 is restricted, thereby restricting the degree of freedom of the lower handle 200 in its length direction, achieving the effect of fixing the position of the lower handle 200 in the guide groove 1.

[0032] Preferably, the width of the locking block 301 is less than the width of the positioning groove 4 and its width is greater than the distance between the two limiting plates 102, so that the limiting member 3 can be embedded in the positioning groove 4, and when the limiting member 3 is embedded in the positioning groove 4, the two limiting platforms 5 respectively abut against the two ends of the locking block 301 near the lower handle 200.

[0033] Furthermore, the limiting member 3 is rotatably connected to the lower handle 200 via a hinge 9, and the rotation axis of the hinge 9 is perpendicular to the length direction of the lower handle 200.

[0034] When the lower handle 200 slides along the guide groove 1 to the preset position, the hinge 9 can be used to flip the locking block 301 toward the positioning groove 4, so that the locking block 301 is embedded in the positioning groove 4. At the same time, the limiting pin 2 is inserted into the positioning hole 302, and the two limiting platforms 5 respectively abut against the two ends of the locking block 301 on the side near the lower handle 200. The limiting pin 2 and the two limiting platforms 5 can restrict the degree of freedom of the locking block 301 in the length direction of the guide groove 1. Since the two ends of the hinge 9 are respectively connected to the locking block 301 and the lower handle 200, the degree of freedom of the lower handle 200 in the length direction of the guide groove 1 can be restricted.

[0035] Furthermore, by engaging the locking block 301 to flip it away from the positioning groove 4, the locking block 301 can be flipped out of the positioning groove 4 and the limiting pin 2 can be disengaged from the positioning hole 302. At this time, the lower handle 200 is free in the length direction of the guide groove 1 and can be pushed to slide further along the guide groove 1 towards the positioning groove 4, so that the overall length of the handle is shortened until the buckle 13 disengages from the corresponding position of the preset slot on the plastic bottle 300, thereby separating the handle from the plastic bottle 300, which facilitates the subsequent classification and recycling of products.

[0036] Alternatively, a flexible thin film can be used instead of hinge 9.

[0037] Furthermore, the handle 100 is provided with a finger relief 6, which is connected to the positioning groove 4, and the locking block 301 is provided with a finger position 7.

[0038] When it is necessary to remove the handle from the plastic bottle 300, the user's fingers can be inserted into the positioning groove 4 through the finger position 6, and the locking block 301 can be pried outward through the finger position 7, making it easier to flip the locking block 301 out of the positioning groove 4.

[0039] Preferably, the locking block 301 is provided with a limiting post 8. When the positioning hole 302 is inserted into the limiting pin 2, the limiting post 8 abuts against the side of the handle 200 near the locking block 301.

[0040] After the handle is assembled, the limiting post 8 provides support and can limit the lower handle 200 from moving further toward the limiting pin 2, effectively dispersing the pressure acting on the hinge 9.

[0041] Furthermore, the limiting pin 2 includes a pin 201, one end of which is fixedly connected to the upper handle 100 of the handle, and the other end of which is connected to a cone 202. The outer diameter of the cone 202 gradually increases towards the pin 201, and the maximum outer diameter of the cone 202 is greater than the outer diameter of the pin 201 to form a buckle 203. This facilitates the locking block 301 to be pressed onto the pin 201 through the positioning hole 302, thereby restricting the degree of freedom of the locking block 301 in the direction perpendicular to the axis of the limiting pin 2. The buckle 203 can also lock the positioning hole 302, effectively restricting the degree of freedom of the locking block 301 in the axial direction of the limiting pin 2.

[0042] Furthermore, a gap is provided on the limiting pin 2, which radially penetrates the limiting pin 2 to form two symmetrical limiting half-pins, making the limiting pin 2 an open structure. When the limiting member 3 connects to the limiting pin 2, the positioning hole 302 can squeeze the two limiting half-pins, causing the two limiting half-pins to deform in the direction of mutual approach, reducing the gap and the outer diameter of the limiting pin 2, so that the limiting pin 2 can be better inserted into the positioning hole 302; and, during the separation of the limiting member 3 and the limiting pin 2, the two limiting half-pins can also be manually pinched together, causing the two limiting half-pins to deform, reducing the gap and the outer diameter of the limiting pin 2, and the buckle 203 no longer fastens the positioning hole 302, making disassembly easier.

[0043] Preferably, the limiting pin 2 is made of plastic and has a certain elastic deformation capability.

[0044] Furthermore, the lower handle 200 is provided with a plurality of weight-reducing grooves 10, which can reduce raw materials and costs; and the lower handle 200 is provided with reinforcing ribs 11, which are arranged along the length direction of the lower handle 200, thereby enhancing the rigidity of the product.

[0045] Working principle of this utility model: When attaching the handle to the plastic bottle 300, first flip the limiting member 3, that is, rotate the locking block 301 about 90° towards the side closer to the weight reduction groove 10 around the pivot of the hinge 9. Then, insert the end of the lower handle 200 near the limiting member 3 into the groove 101 of the upper handle 100 from the open end of the groove 101, and slide it along the groove 101 until it partially extends into the positioning groove 4. At this time, the overall length of the handle is relatively short, so it can be easily placed into the slot of the plastic bottle 300. After the handle enters the slot of the plastic bottle 300, pull the lower handle 200 back to make the end of the lower handle 200 near the limiting member 3 exit the positioning groove 4, and rotate the locking block 301 so that the locking block 301 moves towards the side closer to the weight reduction groove 10. The positioning groove 4 is rotated in the direction until the locking block 301 is embedded in the positioning groove 4. At the same time, the limiting pin 2 is inserted into the positioning hole 302, thereby connecting the upper handle 100 and the lower handle 200 to form a complete handle and locking the relative position between the upper handle 100 and the lower handle 200. Meanwhile, the two buckle pieces 13 are respectively buckled and connected to the corresponding positions of the preset slots on the plastic bottle 300, so that the handle is installed and fixed on the plastic bottle 300, thereby realizing the rear installation. It effectively retains the advantages of the existing rear handle, such as simple process and high production efficiency. At the same time, since no external force is required to bend and deform the handle during installation, the installation is more convenient, and the load-bearing capacity is stronger, and the application range is wider.

[0046] When it is necessary to remove the handle from the plastic bottle 300, the fingers are inserted into the positioning groove 4 through the finger spacer 6 and hooked into the finger position 7. The locking block 301 is pried outward with force, while the two limiting half pins are pressed in the direction that they are close to each other. This can pry the locking block 301 out of the positioning groove 4, and at the same time, the limiting pin 2 is disengaged from the positioning hole 302. At this time, pushing the lower handle 200 forward can shorten the overall length of the handle, so that the handle can be easily and quickly removed from the plastic bottle 300.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
