Abstract
Description
Technical Field
[0001] This utility model relates to the field of handle technology, and in particular to a handle suspension limiting structure and a device using the handle suspension limiting structure. Background Technology
[0002] Many products now come with handles for easy carrying, moving, or transporting. Some handles even have various functions, such as lighting (reading lights), and some with lighting on the hover handle can meet lighting needs at various angles. In addition, some products have hovering mechanisms to allow the handle to hover in different positions for convenient use and efficient space utilization. However, existing hovering mechanisms are complex and involve many components. To address the complexity of hovering mechanisms, some products use damping components to enable the handle to hover. However, damping components have a short lifespan, and the handle will lose its hovering effect due to wear and tear during daily use.
[0003] Therefore, there is an urgent need for a simple hovering structure that can be used for a long time. Utility Model Content
[0004] In order to overcome the shortcomings of existing technologies, such as complex hovering structures or easy loss of hovering limit function due to easy wear of damping components, this utility model provides a handle hovering limit structure and a device using the handle hovering limit structure, which has the advantages of simple structure and long hovering time.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] This utility model provides a handle suspension limiting structure, including a handle and a limiting component. The handle rotates relative to the limiting component. The handle is fixed with a sector tooth, which rotates together with the handle. The limiting component is provided with a receiving cavity, and an elastic locking member is installed in the receiving cavity. The elastic locking member faces the tooth groove side of the sector tooth and engages with the tooth groove.
[0007] By adopting the above technical solution, a fan tooth is set on the handle, and a limiting component is set on the product relative to the fan tooth. The elastic locking part of the limiting component abuts against the fan tooth. The position of the elastic locking part does not move. The handle rotates relative to the limiting component, which drives the fan tooth to rotate. The fan tooth is provided with multiple tooth grooves. The elastic locking part engages with different tooth grooves to achieve hovering at different angles. The structure of this application is simple and easy to assemble. The fan tooth and the elastic locking part are not easy to wear, so that the hovering function can be maintained for a long time.
[0008] Furthermore, the handle includes a handle portion, an axis portion, and a rotating portion, with the two ends of the axis portion connected to the handle portion and the rotating portion, respectively.
[0009] By adopting the above technical solution, the distance of force application of the handle is increased by the axis section. Under the premise that the force required for rotation is certain, the longer the axis section, the longer the vertical distance from the point of force application of the handle section to the sector teeth. This allows the handle to be rotated while applying less force. Because the axis section is set, the force application distance is increased, which saves more effort.
[0010] Furthermore, sector teeth are disposed on the end face of the rotating part and / or the circumferential outer surface of the rotating part.
[0011] Using the above technical solution, the sector teeth can be set on the end face of the rotating part or on the circumferential outer surface of the rotating part. In order to ensure that the rotating part rotates better, the rotating part is a cylinder with a certain length. The end face of the rotating part refers to the side surface away from the axis, and the circumferential outer surface refers to the arc-shaped outer surface of the cylinder of the rotating part. The two setting methods can be selected according to the specific use situation, which can better adapt to the needs of different devices for installing handles.
[0012] Furthermore, the elastic locking component includes a spring and a push button connected in sequence, with the spring positioned close to the inside of the receiving cavity and the push button extending out of the receiving cavity.
[0013] Using the above technical solution, when the handle rotates, the push button slides sequentially between the grooves and tips of the sector teeth. The push button acts on the spring, causing the spring to extend or contract. When the handle is in a suspended state, the push button engages with the grooves of the sector teeth, compressing the spring. The spring then transmits its force to the push button, causing the push button and the sector teeth to engage securely. The structure of the spring and push button engaging the sector teeth is simple and low-cost, making the suspension structure of this application simple in structure and low in manufacturing cost.
[0014] Furthermore, the spring abuts against the push button and / or the spring is fixedly sleeved on the push button.
[0015] Using the above technical solution, the spring can be directly abutted against the push button after installation without being tightly connected, which facilitates maintenance of both devices. Alternatively, the spring can be tightly fitted onto the outer surface of the push button, so that the movement guidance of the push button and the spring is more consistent, resulting in smoother back-and-forth movement of the push button when the sector teeth rotate and compress.
[0016] Furthermore, the push button includes a first push button part and a second push button part connected in sequence. The first push button part is close to the sector teeth, and the end of the first push button part close to the sector teeth is adapted to the shape of the tooth groove to exit and slide into the tooth groove.
[0017] By adopting the above technical solution, the end of the first push button near the fan tooth is adapted to the shape of the tooth groove, which can ensure that the handle is more stable in the suspended state and will not easily slip off.
[0018] Furthermore, the second push button is located near the spring, and the shape of the second push button is adapted to the shape of the receiving cavity.
[0019] By adopting the above technical solution, the shape of the second push button is adapted to the shape of the receiving cavity, and the back-and-forth movement of the second push button can be smoother. The progress of the second push button will not be hindered due to the irregular cross-section of the second push button and the receiving cavity. Preferably, the receiving cavity is set as a cylindrical hole, which can better accommodate the spring and the push button, and the inner wall of the cylindrical hole is smoother, without the rotation restriction of sharp corners.
[0020] Furthermore, a light is installed on the handle.
[0021] By adopting the above technical solution, a light is installed on the handle. In special environments, the handle can be pushed to change the suspension angle of the handle, thereby changing the lighting direction of the light and making the light more suitable for the lighting angle requirements of the current scene.
[0022] Furthermore, the handle also features an anti-slip texture.
[0023] Using the above technical solution, the anti-slip texture can be anti-slip protrusions, anti-slip grooves, and knurling, which can increase the friction of the handle and ensure that the user will not slip when pushing the handle.
[0024] A device using the above-mentioned handle suspension limiting structure includes a housing and a device body. The device body and the limiting component are installed inside the housing. The handle is installed on both sides of the housing. The part of the handle with fan teeth passes through the openings on both sides of the housing and enters the housing, abutting against the elastic locking component.
[0025] The beneficial effects of this utility model are: (1) simple structure and low manufacturing cost; (2) simple disassembly and assembly method and high disassembly and assembly efficiency; (3) will not cause damage to the surface of the spring; (4) can adapt to the disassembly and assembly of energy storage springs of different sizes.

[0033] Example 1:
[0034] This utility model provides a handle suspension limiting structure, such as Figure 1 and Figure 2 As shown, it includes a handle 10 and a limiting component 20. The handle 10 rotates relative to the limiting component 20. The handle 10 is provided with a sector tooth 30, which rotates together with the handle 10. The limiting component 20 is provided with a receiving cavity 21, and an elastic locking member 40 is installed in the receiving cavity 21. The elastic locking member 40 faces the tooth groove 31 of the sector tooth 30, and the elastic locking member 40 and the tooth groove 31 are selectively engaged.
[0035] In practice, when it is necessary to change the hovering angle of the handle 10 hovering limit structure, the handle 10 is held and a rotational force is applied to it, causing the handle 10 to start rotating relative to the limit component 20. At the same time, the handle 10 drives the sector tooth 30 to rotate. At this time, the elastic locking member 40 will slide from the tooth groove 31 and tooth tip of the sector tooth 30 in sequence. During this process, the sector tooth 30 will squeeze the elastic locking member 40, causing the elastic locking member 40 to contract and expand repeatedly until the handle 10 is hovered at the required angle. At this time, the elastic locking member 40 is engaged in the tooth groove 31 of the sector tooth 30 and remains in a hovered state without the application of additional force. The structure used in this application is simple. A sector tooth 30 is set on the handle 10, and a limiting component 20 is set on the product relative to the sector tooth 30. The elastic locking part 40 of the limiting component 20 abuts against the sector tooth 30. The position of the elastic locking part 40 remains unchanged. The handle 10 drives the sector tooth 30 to rotate. Different grooves 31 of the sector tooth 30 and the elastic locking part 40 can be selectively engaged to achieve different angles of suspension. In order to achieve more different angles of suspension, the number of grooves 31 can be set to more than 6, such as 9, 12, or other numbers set as needed. The handle 10 can rotate at an angle of more than 90 degrees. In addition, the sector tooth 30 and the elastic locking part 40 are not easy to wear, so that the suspension function can be maintained for a long time.
[0036] In one embodiment, such as Figure 1 and Figure 2 As shown, the handle 10 includes a handle portion 11, an axis portion 12, and a rotating portion 13. The two ends of the axis portion 12 are connected to the handle portion 11 and the rotating portion 13, respectively.
[0037] The handle part 11 refers to the part where gripping force is applied; the rotating part 13 refers to the part that is directly connected to the product device and can rotate around the product device. The handle part 11 and the rotating part 13 are arranged in parallel; the axis part 12 connects the handle part 11 and the rotating part 13 and transmits the rotation of the rotating part 13 to the handle part 11 to change the position of the handle part 11.
[0038] Specifically, by increasing the distance at which the handle 11 applies force through the axis portion 12, and given a certain amount of force required for rotation, the longer the axis portion 12, the longer the vertical distance from the point of force application of the handle 11 to the sector tooth 30, so that the rotation of the handle 10 can be completed while applying less force. Because the axis portion 12 is provided, the distance at which force is applied is increased, making it more labor-saving.
[0039] It should be noted that the length of the axis part 12 is not better the longer it is, but should be controlled within a reasonable range so that when the handle 10 is in an upright position, the length will not be too long and will not take up too much space.
[0040] In one embodiment, sector teeth 30 are disposed on the end face of the rotating part 13 and / or the circumferential outer surface of the rotating part.
[0041] The sector teeth 30 can be directly injection molded integrally with the rotating part 13, or the metal sector teeth 30 can be embedded or fitted into the rotating part 13.
[0042] Specifically, the sector tooth 30 can be provided only in one of the rotating parts 13. In this case, the receiving cavity 21 does not need to be through, and the suspension requirement of the handle 10 can be met on one side. This utility model preferably uses this solution to reduce the complexity of the suspension structure.
[0043] Alternatively, sector teeth 30 can be provided on both rotating parts 13. In this case, two push buttons 42 are required. Spring 41 is located in the middle of receiving cavity 21. Receiving cavity 21 is provided with an opening. The two push buttons 42 are respectively connected to the two sides of spring 41, extend out from receiving cavity 21, and abut against the sector teeth 30 on the two rotating parts 13.
[0044] The sector teeth 30 can be disposed on the end face of the rotating part 13 or on the circumferential outer surface of the rotating part 13.
[0045] To ensure that the rotating part 13 rotates better, the rotating part 13 is a cylinder with a certain length. The end face of the rotating part 13 refers to the surface on the side away from the axis part 12, and the circumferential outer surface refers to the arc-shaped outer surface of the cylinder of the rotating part 13.
[0046] In one embodiment, the sector teeth 30 can be disposed on the end face of the rotating part 13. In this case, the receiving cavity 21 is collinear with the rotating part 13, and one end of the push button 42 abuts against the sector teeth 30.
[0047] If the sector teeth 30 are set on the axial outer surface of the rotating part 13, a circumferentially arranged tooth structure can be directly injection molded on the circumferential outer surface or a metal tooth ring can be directly sleeved on the outside of the rotating part 13. In this case, the receiving cavity 21 and the elastic locking member 40 installed in the receiving cavity 21 need to be set perpendicular to the circular outer surface of the rotating part 13.
[0048] The present invention preferably places the sector teeth 30 on the end face of the rotating part 13. Since there is a certain gap between the two rotating parts 13, this arrangement can directly place the limiting component 20 between the two rotating parts 13, making reasonable use of space and reducing the space occupied by the product.
[0049] In one embodiment, the elastic locking member 40 includes a spring 41 and a push button 42 connected in sequence. The spring 41 is disposed close to the interior of the receiving cavity 21, and the push button 42 extends out of the receiving cavity 21.
[0050] Among them, the push button 42 is a snap-fit device with one end connected to the spring 41 and the other end snapped into the sector tooth 30.
[0051] In practical implementation, when the handle 10 rotates, the push button 42 slides sequentially between the tooth groove 31 and the tooth tip of the sector tooth 30. The push button 42 actuates the spring 41, causing the spring 41 to extend or contract. When the handle 10 is in a suspended state, the push button 42 engages with the tooth groove 31 of the sector tooth 30, compressing the spring 41. The spring 41 transmits its force to the push button 42, thus securing the push button 42 and the sector tooth 30 together. The structure of the spring 41 and the push button 42 engaging the sector tooth 30 is simple and low-cost, making the suspension structure of this application simple in structure and low in manufacturing cost.
[0052] In one embodiment, the spring 41 abuts against the push button 42 and / or the spring 41 is fixedly sleeved on the push button 42.
[0053] Spring 41 can be directly mounted against push button 42 without being tightly connected, which facilitates maintenance of both devices. Alternatively, spring 41 can be tightly fitted onto the outer surface of push button 42, so that the movement guidance of push button 42 and spring 41 is more consistent, making the back-and-forth movement of push button 42 smoother when sector tooth 30 rotates and compresses.
[0054] The push button 42 includes a first push button part 421 and a second push button part 422 connected in sequence. The first push button part 421 is close to the sector tooth 30. The end of the first push button part 421 close to the sector tooth 30 is adapted to the shape of the tooth groove 31 to exit and slide into the tooth groove 31.
[0055] In practice, the end of the first push button 421 near the sector tooth 30 is adapted to the shape of the tooth groove 31, which can ensure that the handle 10 is more stable in the suspended state and will not easily slip off, while also ensuring that it can smoothly exit and slide into the tooth groove 31 during the rotation of the handle 10.
[0056] Preferably, the groove 31 of the first push button part 421 near the end of the sector tooth 30 is wedge-shaped. This arrangement can better meet the gap requirements of the groove 31, and the top is not a sharp point. Since the sharp point exerts greater pressure on the sector tooth 30, setting it as a non-sharp point will not easily cause wear to the sector tooth 30.
[0057] The second push button 422 is close to the spring 41, and the shape of the second push button 422 is adapted to the shape of the receiving cavity 21.
[0058] In practical implementation, the shape of the second push button 422 is adapted to the shape of the receiving cavity 21, allowing the second push button 42 to move back and forth more smoothly. The movement of the second push button 422 will not be hindered due to the irregular cross-section of the two parts. Preferably, the receiving cavity 21 is a cylindrical cavity, which can better accommodate the spring 41 and the push button 42. Furthermore, the inner wall of the cylindrical cavity is smoother, eliminating the rotational limitations imposed by sharp edges.
[0059] A light 50 is installed on the handle part 11.
[0060] Preferably, the handle 11 can also be equipped with a light 50. In special environments, the handle 10 can be pushed to change the hovering angle of the handle 10, thereby changing the lighting direction of the light 50, so that the light 50 can better meet the lighting angle requirements of the current scene.
[0061] The handle portion 11 is also provided with an anti-slip texture 60. The anti-slip texture 60 can be an anti-slip protrusion, an anti-slip groove, or a knurled pattern, which can increase the friction of the handle portion 11 and ensure that the user will not slip when pushing the handle portion 11.
[0062] Example 2:
[0063] This utility model also provides a device that uses the above-mentioned handle 10 suspension limiting structure, including a housing 1 and a device body 2. The device body 2 and the limiting component 20 are installed inside the housing 1. The handle 10 is installed on both sides of the housing 1. The part of the handle 10 with the fan tooth 30 passes through the openings on both sides of the housing 1 and enters the interior of the housing 1, abutting against the elastic locking member 40.
[0064] Specifically, the aforementioned hovering limiting device can be installed on any device requiring a hovering structure, without specific limitations. A certain space can be reserved in the upper housing 1 of the device, and hovering structures can be provided on both sides of the housing 1 for the rotating part 13 to pass through and mount the handle 10. The position of the sector teeth 30 can be specifically selected according to the device. If installing the sector teeth 30 at the end of the rotating part 13 occupies less space in the housing 1, the sector teeth 30 can be positioned at the end of the rotating part 13, and the limiting component 20 is positioned between the two rotating parts 13, with the elastic locking member 40 perpendicular to the end face of the sector teeth 30. If installing the sector teeth 30 on the circumferential outer surface of the rotating part 13 can reduce the space occupied in the housing 1, the sector teeth 30 can be positioned on the circumferential outer surface of the rotating part 13, and the limiting component 20 is installed relative to the sector teeth 30 on the side wall of the housing 1. Preferably, the limiting component 20 is connected to the side wall of the housing 1 by bolts.
[0065] like Figure 3 and Figure 4 These are the maximum angles at which the handle 10 can hover relative to its lowest point, and these angles are... Figure 5 As shown in the figure, θ is preferably 125° in this utility model. It should be noted that it is not limited to the above angle, and can also be other angles that are not blocked by the shell 1. Figure 5 and Figure 6 As shown, the handrail is in its lowest position. Because the bottom is blocked by the housing 1, the handle 10 cannot be fully lowered. The specific lowest point is determined by the position of the housing 1 and the handle 10.
