[0002] In the field of electronic balances, the balance wind shield is an indispensable part. Usually, high-precision electronic balances are easily affected by external conditions during use, such as air flow, natural wind, and external vibrations, which will cause the weighing of the electronic balance to fluctuate. The role of the balance wind shield is to effectively improve the influence of these external factors, so as to make the weighing data more accurate.
[0003] In the prior art, there are usually two ways to connect the handle of the balance wind shield: the first way is to use a wind shield handle with an external thread and a wind shield handle cap with an internal thread to cooperate to complete the function. The second way is to use double-sided tape on the wind shield handle to fix it to complete the function. The balance wind shield is connected through the wind shield handle to complete the opening and closing functions of the wind shield glass.
[0004] However, the handle connection mechanism of the above-mentioned balance wind shield has the following problems:
[0005] 1. If the first method is adopted, both the hood handle and the handle cap have threads, which is relatively complicated to process and has high cost. It is easy to wear and damage after long-term use, which poses quality risks and poor customer experience.

[0081] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0082] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Reference will now be made in detail to preferred embodiments of the present invention, examples of which are shown in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings to represent the same or similar parts.
[0083] Furthermore, although the terms used in the present invention are selected from well-known and commonly used terms, some terms mentioned in the present invention specification may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this document.
[0084] Furthermore, it is required that the present invention be understood not only by the actual terms used but also by the meanings connoted by each term.
[0085] like Figure 1 As shown, the present invention discloses an electronic balance, which includes a balance wind shield 100 and a balance body 200. The balance wind shield 100 is installed on the balance body 200.
[0086] like Figure 2 As shown, the present invention discloses a balance wind shield 100 with a handle, comprising a wind shield upper cover 110, a wind shield top glass 120, a wind shield side glass 130, a plurality of wind shield columns 140, a wind shield bottom shell 150, a handle 160 and a fixing block 170. The wind shield upper cover 110, the wind shield bottom shell 150 and the plurality of wind shield columns 140 are surrounded to form a frame structure, the wind shield top glass 120 is installed on the wind shield upper cover 110, and the wind shield side glass 130 is installed around the wind shield upper cover 110, the wind shield columns 140 and the wind shield bottom shell 150 to form a complete wind shield.
[0087] like Figure 3 and Figure 4 As shown, the handle 160 is inserted from one side of the wind shield top glass 120, and is fixed on the other side of the wind shield top glass 120 by the fixing block 170. The wind shield glass here takes the wind shield top glass 120 as an example. Of course, in fact, the glass of other parts of the wind shield, such as side glass, front glass, rear glass, etc., can also use this solution if needed. Only one place is selected as an example here, but it is not limited. The glass installed in other parts of the handle 160 is within the protection scope of this application.
[0088] More specifically, at least one positioning hole 121 is provided on the wind shield glass (e.g., wind shield top glass 120), and at least one fixing portion 161 is provided at the bottom of the handle 160. The fixing portion 161 is passed through the positioning hole 121 from one side of the wind shield glass (e.g., wind shield top glass 120) to the other side of the wind shield glass (e.g., wind shield top glass 120). The fixing block 170 is located on the other side of the wind shield glass (e.g., wind shield top glass 120) and is locked with the fixing portion 161, thereby locking the handle 160 to the wind shield glass (e.g., wind shield top glass 120).
[0089] It is worth noting that the locking connection here is in a detachable form, and the handle 160 and the fixing block 170 can be connected and disassembled according to actual needs, thereby taking into account both convenience and installation efficiency.
[0090] For example, in this embodiment, a fixing portion 161 is respectively provided at both ends of the bottom of the handle 160, and two positioning holes 121 are provided on the wind shield glass (such as the wind shield top glass 120), and the positions of the positioning holes 121 correspond to the positions of the fixing portions 161.
[0091] like Figures 5 to 7 As shown, the fixing portion 161 of the handle 160 includes a columnar body 162 and a clamping portion 163. The clamping portion 163 is arranged at the bottom end of the columnar body 162, and the clamping portion 163 extends outward along the bottom end of the columnar body 162 to form a pair of clamping areas arranged oppositely. The clamping area is provided with two sliding guide surfaces 1631, and the two sliding guide surfaces 1631 are connected by a handle upper and lower fixed contact surface 1632. For example, the sliding guide surface 1631 can be selected as a smooth concave arc transition surface, and the handle upper and lower fixed contact surface 1632 is a convex surface. The clamping area here refers to the part of the clamping portion 163 that protrudes to both sides along the columnar body 162 for clamping. The sliding guide surface 1631 refers to an inclined surface arranged on the upper surface of the clamping area for smoother clamping.
[0092] In one embodiment, a handle groove 1621 is formed on the columnar body 162 of the fixing portion 161 and is adjacent to the upper and lower fixing contact surfaces 1632 of the handle. A handle horizontal contact area 1622 is also formed on the columnar body 162 of the fixing portion 161 and is located on both sides of the handle groove 1621 .
[0093] In another embodiment, a longitudinal groove 1633 may be provided on at least one side of the columnar body 162 of the fixing portion 161. For example, in this embodiment, longitudinal grooves 1633 are provided on both sides of the columnar body 162, so that the cross section of the fixing portion 161 is an H-shaped structure 1611.
[0094] According to the inventive concept of the technical solution of this application, the groove 1633 here may not be provided, may be provided singly, or may be provided in multiples. The form of the groove 1633 may be a structure that passes through the columnar body 162, or may be a structure that is provided in a partial area of the columnar body 162. In other words, there is no limitation on the number and structure of the grooves 1633, and they may be adjusted according to actual needs, all within the scope of protection of this application. The provision of the groove 1633 here can mainly serve the purpose of increasing elasticity and reducing weight.
[0095] The fixing part 161 can be supported by a plastic material with a certain elasticity, so that when the columnar body 162 of the fixing part 161 is squeezed, the strength is increased and a certain plastic deformation can be generated, which facilitates the assembly of the fixing block 170 and the handle 160 .
[0096] At the same time, due to its special H-shaped structure, the wall thickness of the plastic material is more uniform, which reduces the occurrence of "shrinkage" from the perspective of plastic mold molding and improves product quality. In addition, by adjusting the thickness of the middle reinforcing rib of the H-shaped structure, the deformation and strength of the fixing portion 161 of the handle 160 can be adjusted.
[0097] In another embodiment, if Figure 5 As shown, a protrusion 164, i.e., a handle touch indication protrusion, can be further provided on the side wall surface of the handle 160 to indicate the touch position. The purpose of providing the protrusion 164 is to enhance the touch feeling, remind the customer of the touch position, and facilitate the customer to complete the opening and closing action of the wind shield glass (e.g., the wind shield top glass 120) by pushing the handle.
[0098] like Figures 8 to 10As shown, a cavity 171 is provided on the upper end surface of the fixing block 170, and at least one set of locking structures 172 is provided on the two side walls of the cavity 171, and the engaging area of the fixing portion 170 engages with the corresponding locking structure 172. The cavity 171 here can be a connected integral space, or can be a plurality of independent small spaces for installing the locking structure 172, so that there is a space between the locking structure 172 and the bottom of the fixing block 170, so that the engaging area of the fixing portion 170 can be engaged.
[0099] Preferably, each set of locking structures 172 includes a pair of cantilever beam hooks 173 arranged oppositely, each pair of cantilever beam hooks 173 are arranged oppositely on the two side walls of the cavity 171, and a slot 1731 is formed between the cantilever beam hooks 173. When the handle 160 is locked with the fixing block 170, the columnar body 162 of the fixing portion 161 is installed in the slot 1731 through the sliding guide surface 1631, the engaging portion 163 is engaged with the bottom of the corresponding cantilever beam hook 173, and the upper and lower fixed contact surfaces 1632 of the handle are against the bottom end surface of the corresponding cantilever beam hook 173.
[0100] Here, if Fig.10 As shown, the bottom end surface of the cantilever beam hook 173 is the upper and lower locking contact surface 1732 of the fixing block, and the upper and lower locking contact surface 1732 of the fixing block can be set as an inclined surface.
[0101] Further, in one embodiment, a deformation avoidance space 174 is provided between the cantilever beam hook 173 and the upper end surface of the fixed block 170. The end of the cantilever beam hook 173 includes two sections of hook horizontal guide areas 1733 and a section of hook top 1734, and the hook top 1734 is connected between the two sections of hook horizontal guide areas 1733. When the columnar body 162 of the fixed part 160 is installed in the slot 1731 through the sliding guide surface 1631, the hook top 1734 of the cantilever beam hook 173 is inserted into the handle groove 1621, and the handle horizontal contact area 1622 contacts the hook horizontal guide area 1733 in the horizontal direction. When the fixed block 170 is pushed by hand so that its hook top 1734 is inserted into the handle groove 1621, the upper and lower locking contact surfaces 1732 of the fixed block can slide relatively easily along the sliding guide surface 1631.
[0102] When the hook top 1734 is inserted into the handle groove 1621, the upper and lower fixed contact surfaces 1632 of the handle and the upper and lower locking contact surfaces 1732 of the fixing block contact each other. From the perspective of product design, a certain amount of interference is designed in the vertical contact area of the two parts. Fig.14As shown, a pair of interaction forces are generated between the upper and lower fixed contact surfaces 1632 of the handle and the upper and lower locking contact surfaces 1732 of the fixed block. Since a certain deformation avoidance space 174 is designed on the upper part of the cantilever beam hook 173, the cantilever beam hook 173 can be deformed and moved upward due to being squeezed. So far, the cantilever beam hook 173 is always subjected to a vertical upward force, so that the bottom surface of the fixed block 170 and the wind shield glass (such as the wind shield top glass 120) are always in close contact. For the handle 160, it is always subjected to a vertical downward force, so that the handle 160 and the top surface of the wind shield glass (such as the wind shield top glass 120) are always in close contact. The handle 160 and the fixed block 170 are always tightly connected in the vertical direction, and the relative position is effectively fixed.
[0103] like Fig.11 As shown, hold the handle 160 and the wind shield glass (for example, the wind shield top glass 120) so that the two fixing parts 161 on the handle 160 and the two positioning holes 121 on the wind shield glass (for example, the wind shield top glass 120) are in a concentric relative position in the vertical direction, and then insert the fixing part 161 of the handle 160 into the positioning hole 121. Place the fixing block 170 directly below the handle 160, and adjust the relative position of the fixing block 170 so that the pre-locking position (i.e., the locking structure 172) of the fixing block 170 coincides with the projection of the fixing part 161 of the handle 160 on the fixing block 170. At this time, push the fixing block 170 vertically upward, and the fixing part 161 of the handle 160 is located at the pre-locking position (i.e., the locking structure 172) of the fixing block 170. The installation effect is as shown in FIG. Fig.12 shown.
[0104] During the installation process, Fig.12 When the state is , the horizontal cross section of the relevant assembly position can be obtained. Fig.15 It can be more clearly seen that the fixing portion 161 on the handle 160 is located at the pre-locking position of the fixing block 170 (ie, the locking structure 172).
[0105] Keeping the above state, push the fixing block 170 so that the fixing column 161 of the handle 160 passes over the pre-locking position of the fixing block 170, and a "click" sound is heard, and it reaches the locking position. The installation effect is as follows: Fig.13 shown.
[0106] During the installation process, Fig.13 When the state is reached, the horizontal cross section of the relevant assembly position can be obtained. Fig.16 It can be more clearly seen that the handle fixing column 161 on the handle 160 is in the locked position.
[0107] The technical solution of the present application can design multiple cantilever beam hooks 173 on the fixing block 170. Since their functions and structures are the same, we will take one of them for illustration. Figure 12 to Figure 13 , Figure 15 to Figure 16 During the process), first, the horizontal guide area 1733 of the hook contacts the fixed portion 161 of the handle 160, which serves as a sliding guide for the fixed portion 161 of the handle 160, and the fixed block 160 is continuously pushed, and the top 1734 of the hook on the cantilever beam hook 173 can be inserted into the handle groove 1621.
[0108] When the handle on the wind shield glass is in a locked state, in the horizontal direction, the handle horizontal contact area 1622 on the handle 160 and the hook horizontal guide area 1733 on the fixing block 170 are in contact with each other. From the perspective of product design, a certain amount of interference is designed in the horizontal contact area of the two parts. Fig.16 , so that after being installed in place, a certain compression deformation occurs between the handle horizontal contact area 1622 and the hook horizontal guide area 1733, thereby generating a pair of interaction forces. In addition, the cooperation between the handle groove 1621 and the hook top 1734 effectively fixes the relative position of the handle 160 and the fixing block 170 in the horizontal direction.
[0109] During the installation process Fig.13 When the state is , the relevant assembly position is vertically sectioned, and it can be obtained Fig.14 As shown. Fig.13 and Fig.14 It can be seen that the handle glass contact surface 165 on the handle 160 is in close contact with the upper surface of the wind shield glass (e.g., the wind shield top glass 120). The fixed block glass contact surface 175 of the fixed block 170 is in close contact with the lower surface of the wind shield glass (e.g., the wind shield top glass 120), and the fixing portion 161 on the handle 160 has been inserted into the positioning hole 121 on the wind shield glass (e.g., the wind shield top glass 120), so the relative position of the wind shield glass (e.g., the wind shield top glass 120) in the horizontal and vertical directions is effectively fixed.
[0110] As described above, the handle 160, the wind shield glass and the fixing block 170 are fixed together stably and effectively, thereby completing the opening and closing functions of the wind shield glass door.
[0111] In summary, the balance wind shield with a handle and the electronic balance including the same of the present invention have the following advantages:
[0112] First, the wind shield glass can be fixed by tightly connecting the clamping groove on the handle and the cantilever beam clamp on the fixing block.
[0113] Second, the balance wind hood has a simple structure, is easy to implement, and can effectively reduce costs.
[0114] 3. The optimized structure of the balance wind hood can effectively improve efficiency and reliability.
