Abstract
Description
Technical Field
[0001] The utility model relates to the field of electronic scales, in particular to a self-locking handle of an electronic scale and a portable electronic scale assembly. Background Art
[0002] At present, the handles of electronic express scales on the market can basically be pulled and rotated freely. When users carry express scales and walk, the handles need to meet certain strength, so they are equipped with metal handles inside. The handles have certain weight, and the handles are very easy to follow the rapid swing. When the handles swing, it is very easy to hit the back of the hand or fingers, elbows, etc. In addition, it is inconvenient to put the handle into the pocket when it automatically comes out to the longest length. It needs to be manually retracted to the shortest length before putting it in. However, the handle is easy to come out when walking, which affects work efficiency. For this reason, some products on the market consider the problem of swing control and make a sleeve groove on the side of the scale body to control the swing of the handle, but this will increase the size of the scale body and make it difficult to put it into the pocket and take it out; there are also products that control the handle not to come out automatically. The main solution is to set two strong magnets at the contact position between the top of the handle and the top surface of the scale body, so that the handle will not automatically come out when it is stored through magnetic attraction. Due to the addition of magnets, the manufacturing cost is increased, and when the magnet is installed on the top surface of the scale body, in order to increase the magnetic attraction, the top surface glue position of the fixed magnet needs to be made thinner so that the magnet is closer during magnetic attraction, which will produce poor appearance of thickness printing during injection molding. Therefore, the portable electronic scales in the prior art cannot take into account both the ease of use and the low cost. Utility Model Content
[0003] The utility model aims to provide a self-locking handle for an electronic scale and a portable electronic scale assembly, which can reduce the processing and manufacturing cost while meeting the requirements of convenient and flexible use.
[0004] The embodiment of the utility model is achieved as follows:
[0005] In a first aspect, the utility model provides a self-locking handle for an electronic scale, comprising:
[0006] A scale case, a positioning shaft and a handle body; the positioning shaft is installed on the scale case, and the positioning shaft and the scale case are relatively fixed in the circumferential direction of the positioning shaft; an assembly hole is provided on the handle body, and the assembly hole is provided with a connected rotating hole portion and an anti-rotation hole portion connected to the rotating hole portion, and the positioning shaft is passed through the assembly hole and slidably matched with the assembly hole, so that the positioning shaft has a first working state and a second working state that can be switched with each other;
[0007] When in the first working state, the positioning shaft and the handle body are rotatably matched; when in the second working state, the positioning shaft and the handle body are damping matched and the two are relatively fixed in the circumferential direction of the positioning shaft.
[0008] In an optional embodiment, the positioning shaft is provided with a first damping surface, and the handle body is provided with a second damping surface, and the first damping surface is used to contact the second damping surface when the positioning shaft is in the second working state.
[0009] Based on the above scheme, through the design of the first damping surface and the second damping surface, when the positioning shaft slides into the anti-rotation hole, the first damping surface and the second damping surface are in contact, thereby increasing the friction between the positioning shaft and the handle body. The positioning shaft and the handle body are not easy to slide freely, and the two are firmly combined. When the electronic scale is put into a pocket and stored, the handle body is not easy to slide and extend, which saves the user the step of repeatedly adjusting the position of the handle body and reduces the time required for the user to repeatedly adjust the handle, which is not easy to affect the user's work efficiency.
[0010] In an optional embodiment, the positioning shaft includes a connected shaft body and an end cap, the shaft body is slidably matched with the assembly hole, and the first damping surface is provided on the end cap.
[0011] Based on the above solution, by providing the end cap, the positioning shaft can be prevented from escaping from the rotating hole of the handle body, thereby improving the stability of the structure.
[0012] In an optional embodiment, the end cap is integrally formed with the shaft body or is fixed by screwing.
[0013] Based on the above scheme, when the end cap and the shaft body are integrally formed, the shaft body and the end cap are firmly and reliably combined, the structural strength is high, and the service life is long. When the end cap and the shaft body are connected together by screw connection, the assembly method of the end cap and the shaft body is simple, easy to disassemble and assemble, and flexible to use. The assembly method of the shaft body and the end cap can be rotated according to the needs, and the manufacturing is flexible.
[0014] In an optional embodiment, an anti-rotation plane is provided on the outer circumferential surface of the positioning shaft, and the anti-rotation plane is used to contact the hole wall of the anti-rotation hole portion when the positioning shaft is in the second working state to limit the relative rotation of the positioning shaft and the handle body.
[0015] Based on the above solution, after the positioning shaft slides into the anti-rotation hole, the anti-rotation plane contacts the hole wall of the anti-rotation hole, and the two are in plane contact, so the anti-rotation effect is good.
[0016] In an optional embodiment, the anti-rotation planes are provided in two numbers and are symmetrically arranged, and the two anti-rotation planes are respectively in contact with two opposite hole walls of the anti-rotation hole portion.
[0017] Based on the above solution, by providing two anti-rotation planes, both anti-rotation planes can contact the hole wall of the anti-rotation hole, thereby increasing the contact area and improving the anti-rotation effect.
[0018] In an optional embodiment, a first anti-rotation structure is provided on the scale case, and a second anti-rotation structure is provided on the outer circumference of the positioning shaft, and the first anti-rotation structure and the second anti-rotation structure are snap-fitted to limit the relative rotation of the positioning shaft and the scale case.
[0019] Based on the above scheme, the first anti-rotation structure and the second anti-rotation structure are snap-fitted together, so that the combination of the positioning shaft and the scale housing is firm and reliable, the two are not easy to rotate relative to each other, and the use is safe and reliable.
[0020] In an optional embodiment, one of the first anti-rotation structure and the second anti-rotation structure is configured as a protrusion, and the other of the two is configured as a groove that is snap-fitted with the protrusion.
[0021] Based on the above solution, the first anti-rotation structure and the second anti-rotation structure have simple structures, are easy to manufacture and assemble. For example, the first anti-rotation structure can be set as a protrusion, and the second anti-rotation structure can be set as a groove.
[0022] In an optional embodiment, the self-locking handle of the electronic scale further includes a protective shell, and the protective shell is connected to the handle body.
[0023] Based on the above solution, the protective shell protects the handle body, the handle body is not easily damaged, and the protective shell can be held when using the electronic scale to improve comfort.
[0024] In a second aspect, the utility model provides a portable electronic scale assembly, the portable electronic scale assembly comprising:
[0025] The self-locking handle of the electronic scale according to any one of the aforementioned embodiments.
[0026] The beneficial effects of the embodiments of the utility model are:
[0027] In summary, the self-locking handle of the electronic scale provided in this embodiment can adjust the working state according to the demand. When the electronic scale is used normally, that is, when the electronic scale is used to weigh an object, the positioning shaft is in the first working state. At this time, the positioning shaft is inserted into the rotating hole portion. The user holds the handle body, and the handle body can rotate around the positioning shaft, which is conducive to the state adjustment of the electronic scale during weighing. After the weighing is completed, the handle body is operated so that the anti-rotation hole portion on it cooperates with the positioning shaft, and the positioning shaft is in the second working state. Since the positioning shaft is in the anti-rotation hole portion, the positioning shaft will not rotate. Therefore, the handle body will not swing freely when carrying the electronic scale, and it is not easy to collide with the user's hand. In addition, since the positioning shaft and the handle body are damping matched, the two are not easy to slide freely. The positioning shaft is not easy to slide relative to the handle body or enter the rotating hole portion without the action of external force. In this way, the position of the handle body is stable, and it is convenient to carry and store. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0036] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0038] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0039] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0040] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0041] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0042] At present, the handle of a portable electronic scale needs to move relative to the scale body when in use, so as to ensure that the scale body is in a suspended state when weighing. When the electronic scale is not in use, the swing of the handle will collide with the user's hand, making it inconvenient to use. In order to improve the swing of the handle, some electronic scales add strong magnets to attach the handle to the scale body when the handle is not in use, which increases the cost of use.
[0043] In view of this, the designer provides a self-locking handle for an electronic scale, which can not only ensure that the handle is not easy to swing relative to the scale body when carrying and storing, but also reduce processing and manufacturing costs.
[0044] Please combine Figure 1-Figure 5 In this embodiment, the self-locking handle of the electronic scale includes a scale housing 100, a positioning shaft 200 and a handle body 300. The positioning shaft 200 is mounted on the scale housing 100, and the positioning shaft 200 and the scale housing 100 are relatively fixed in the circumferential direction of the positioning shaft 200; the handle body 300 is provided with an assembly hole, and the assembly hole is provided with a connected rotating hole portion 321 and an anti-rotation hole portion 322 connected to the rotating hole portion 321. The positioning shaft 200 is penetrated in the assembly hole and slidably cooperates with the assembly hole, so that the positioning shaft 200 has a first working state and a second working state that can be switched with each other; when in the first working state, the positioning shaft 200 and the handle body 300 are rotatably matched; when in the second working state, the positioning shaft 200 and the handle body 300 are damped and matched and the two are relatively fixed in the circumferential direction of the positioning shaft 200.
[0045] Based on the above, the use of the self-locking handle of the electronic scale provided in this embodiment is as follows:
[0046] When the electronic scale is used normally, that is, when the electronic scale is used to weigh an object, the positioning shaft 200 is in the first working state. At this time, the positioning shaft 200 is inserted into the rotating hole 321. When the user holds the handle body 300, the handle body 300 can rotate around the positioning shaft 200, which is conducive to the state adjustment of the electronic scale during weighing. After the weighing is completed, the handle body 300 is operated to make the anti-rotation hole 322 on it cooperate with the positioning shaft 200, and the positioning shaft 200 is in the second working state. Since the positioning shaft 200 is in the anti-rotation hole 322, the positioning shaft 200 will not rotate. Therefore, the handle body 300 will not swing freely when the electronic scale is carried for movement, and it is not easy to collide with the user's hand. Furthermore, since the positioning shaft 200 and the handle body 300 are damped, the two are not easy to slide freely. The positioning shaft 200 is not easy to slide relative to the handle body 300 or enter the rotating hole 321 without the action of external force. In this way, the position of the handle body 300 is stable, and it is convenient to carry and store.
[0047] The details of the self-locking handle of the electronic scale in the embodiment of the present application are described below by way of examples.
[0048] Please combine Figure 4 and Figure 5, wherein the handle body 300 is configured as a U-shaped member, the handle body 300 includes a middle connecting rod 310 and an assembly rod 320 connected to both ends of the connecting rod 310, the connecting rod 310 and the two assembly rods 320 can be configured as an integrated structure, so that the handle body 300 has high structural strength and a long service life. For example, the handle body 300 can be configured as a metal part, which is easy to process and manufacture, and has high structural strength and is not easy to deform or damage.
[0049] At the same time, each assembly rod 320 is provided with an assembly hole, and the positioning shaft 200 is used in conjunction with two assembly rods 320 at the same time. The assembly modes of the two ends of the positioning shaft 200 and the two assembly rods 320 are set to be the same. For the convenience of description, the following embodiment uses the matching structure of one assembly rod 320 and one end of the positioning shaft 200 as an example for explanation. When the positioning shaft 200 is assembled with the two assembly rods 320 at the same time, each assembly rod 320 has a relative inner side and outer side, and the two ends of the positioning shaft 200 extend out of the outer side from the inner side of the corresponding assembly rod 320. After the positioning shaft 200 is fixed to the scale housing 100, the rotating hole portion 321 is located on the side of the anti-rotation hole portion 322 close to the scale housing 100, and the anti-rotation hole portion 322 is a strip hole, and the length of the anti-rotation hole portion 322 extends in the length direction of the assembly rod 320, and the end of the anti-rotation hole portion 322 is spaced from the connecting rod 310.
[0050] In this embodiment, the positioning shaft 200 is provided with a first damping surface 221, and the outer side surface of the assembly rod 320 is provided with a second damping surface 323, and the first damping surface 221 is used to contact the second damping surface 323 when the positioning shaft 200 is in the second working state. Through the design of the first damping surface 221 and the second damping surface 323, when the positioning shaft 200 slides into the anti-rotation hole 322, the first damping surface 221 and the second damping surface 323 contact, thereby increasing the friction between the positioning shaft 200 and the handle body 300, and the positioning shaft 200 and the handle body 300 are not easy to slide freely, and the two are firmly combined. When the electronic scale is put into a pocket and stored, the handle body 300 is not easy to slide and extend, eliminating the step of the user repeatedly adjusting the position of the handle body 300, reducing the time required for the user to repeatedly adjust the handle, and not easy to affect the user's work efficiency.
[0051] It should be understood that the first damping surface 221 and the second damping surface 323 can achieve the damping effect by controlling the gap between the two, or by disposing an elastic layer or other structure on one of the two.
[0052] Please combine Figure 4Optionally, the positioning shaft 200 includes a connected shaft body 210 and an end cap 220, the shaft body 210 is slidably matched with the assembly hole, and the first damping surface 221 is provided on the end cap 220. That is, after the positioning shaft 200 is assembled into the assembly hole, the end cap 220 is located outside the assembly rod 320, and the two assembly rods 320 are located between the two end caps 220, so as to prevent the handle body 300 from coming out relative to the positioning shaft 200 in the axial direction of the positioning shaft 200.
[0053] For example, the end cap 220 and the shaft body 210 can be set as an integrated structure, or the end cap 220 and the shaft body 210 can be set to be screwed and fixed. When the end cap 220 and the shaft body 210 are formed as one piece, the shaft body 210 and the end cap 220 are firmly and reliably combined, the structural strength is high, and the service life is long. When the end cap 220 and the shaft body 210 are set to be screwed together, the assembly method of the end cap 220 and the shaft body 210 is simple, easy to disassemble and assemble, and flexible to use. The assembly method of the shaft body 210 and the end cap 220 is rotated according to the needs, and the manufacturing is flexible.
[0054] Specifically, the end surface of the shaft body 210 can be set as a threaded hole, and the end cap 220 can be provided with a stud, which is screwed and fixed with the threaded hole. During assembly, the stud can be passed through the assembly hole from the outside of the assembly hole, so as to be screwed with the shaft body 210 located on the inner side of the assembly rod 320.
[0055] In this embodiment, optionally, an anti-rotation plane 211 is provided on the outer peripheral surface of the shaft body 210 of the positioning shaft 200, and the anti-rotation plane 211 is used to contact the hole wall of the anti-rotation hole portion 322 when the positioning shaft 200 is in the second working state to limit the relative rotation of the positioning shaft 200 and the handle body 300. After the positioning shaft 200 slides into the anti-rotation hole portion 322, the anti-rotation plane 211 contacts the hole wall of the anti-rotation hole portion 322, and the two are in planar contact, and the anti-rotation effect is good.
[0056] Furthermore, two anti-rotation planes 211 are provided and arranged symmetrically, and the two anti-rotation planes 211 respectively contact two opposite hole walls of the anti-rotation hole portion 322. By providing two anti-rotation planes 211, both anti-rotation planes 211 can contact the hole wall of the anti-rotation hole, increasing the contact area and improving the anti-rotation effect.
[0057] Please combine Figure 3 and Figure 4In this embodiment, optionally, a first anti-rotation structure 110 is provided on the scale housing 100, and the first anti-rotation structure 110 can be set as a protrusion or a groove. A second anti-rotation structure 230 is provided on the outer peripheral surface of the shaft body 210 of the positioning shaft 200, and the second anti-rotation structure 230 can be set as a concave-convex or a protrusion that cooperates with the first anti-rotation structure 110, that is, when the first anti-rotation structure 110 is a protrusion, the second anti-rotation structure 230 is a groove, and vice versa, when the first anti-rotation structure 110 is a groove, the second anti-rotation structure 230 is set as a protrusion. With such a design, the first anti-rotation structure 110 and the second anti-rotation structure 230 are snap-fitted and matched, which can effectively limit the relative rotation of the positioning shaft 200 and the scale housing 100.
[0058] It should be noted that the scale housing 100 can be configured as a structure in which a bottom housing 120 and a front housing 130 cooperate to clamp the positioning shaft 200, which is convenient for assembly. At the same time, both ends of the positioning shaft 200 extend out of the opposite sides of the scale housing 100. The bottom housing 120 and the front housing 130 can be connected by a structure such as a buckle or a screw.
[0059] In this embodiment, optionally, the self-locking handle of the electronic scale further includes a protective shell 400, which is connected to the handle body 300. The protective shell protects the handle body 300, the handle body 300 is not easily damaged, and the protective shell 400 can be held when using the electronic scale to improve comfort.
[0060] It should be understood that the protective shell 400 can be set as a structure in which the first half shell 410 and the second half shell 420 cooperate. The first half shell 410 and the second half shell 420 can be connected by a structure such as a buckle or a screw, and the first half shell 410 and the second half shell 420 cooperate to clamp the handle body 300. An avoidance hole is formed at the connection between the first half shell 410 and the second half shell 420, and the positioning shaft 200 passes through the avoidance hole and then penetrates into the assembly hole on the handle body 300.
[0061] The self-locking handle of the electronic scale provided in this embodiment has a simple structure, is safe to use, and has low cost.
[0062] Please combine Figure 1 and Figure 2This embodiment also provides a portable electronic scale assembly, which includes a self-locking handle for the electronic scale. Obviously, the portable electronic scale assembly also includes other basic components for realizing its weighing function. For example, the portable electronic scale assembly also includes a control board 001, a display 002, a weighing sensor 003, a tape measure 004, and a hook 005. The control board 001, the display 002, the weighing sensor 003, the tape measure 004, and the hook 005 are all installed on the scale housing 100. The control board 001 is electrically connected to the display 002 and the weighing sensor 003 at the same time. The tape measure 004 is connected to the weighing sensor 003, and the weighing sensor 003 is connected to the hook 005. The hook 005 can pull the tape measure 004 to move and apply pressure to the weighing sensor 003. The hook 005 is used to hang objects to achieve weighing. In order to avoid repeated description in this embodiment, the structure and assembly relationship of the components are not described in detail. In addition, the portable electronic scale assembly can also be provided with a rechargeable battery 006 to provide power requirements. The control panel 001 can be provided with physical buttons or touch buttons.
