Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

Furthermore, although terms used in the present utility model are selected from publicly known and commonly used terms, some terms mentioned in the present specification may be selected by the applicant at his or her discretion, the detailed meanings of which are described in relevant parts of the description herein.

Furthermore, it is required that the present utility model is understood, not simply by the actual terms used but by the meaning of each term lying within.

As shown in fig. 1, the present utility model discloses an electronic balance, which includes a balance cover 100 and a balance body 200. The balance cover 100 is mounted on the balance body 200.

As shown in fig. 2, the utility model discloses a balance fan housing 100 with a handle, which comprises a fan housing upper cover 110, a fan housing top glass 120, a fan housing side glass 130, a plurality of fan housing upright posts 140, a fan housing bottom shell 150, a handle 160 and a fixing block 170. The fan cover upper cover 110, the fan cover bottom shell 150 and the fan cover upright posts 140 are surrounded to form a frame structure, the fan cover top glass 120 is arranged on the fan cover upper cover 110, and the fan cover side glass 130 is arranged between the fan cover upper cover 110, the fan cover upright posts 140 and the fan cover bottom shell 150 in a surrounding manner to form a complete fan cover.

As shown in fig. 3 and 4, the handle 160 is penetrated by one side of the cover top glass 120 and fixed on the other side of the cover top glass 120 by the fixing block 170. The cover glass is exemplified by cover top glass 120, although in practice other cover glass portions, such as side glass, front glass, rear glass, etc., may be used if desired. By way of example only, and not limitation, glass with the handle 160 attached to other locations is within the scope of the present application.

More specifically, at least one positioning hole 121 is formed in a cover glass (for example, a cover top glass 120), at least one fixing portion 161 is formed at the bottom of a handle 160, the fixing portion 161 passes through the positioning hole 121 from one side of the cover glass (for example, the cover top glass 120) to the other side of the cover glass (for example, the cover top glass 120), and a fixing block 170 is located at the other side of the cover glass (for example, the cover top glass 120) and is in locking connection with the fixing portion 161, so that the handle 160 is locked on the cover glass (for example, the cover top glass 120).

It should be noted that the locking connection is in a detachable form, and the handle 160 and the fixing block 170 can be connected and detached according to practical needs, so as to achieve convenience and installation efficiency.

For example, in this embodiment, two fixing portions 161 are respectively disposed at two ends of the bottom of the handle 160, two positioning holes 121 are disposed on the cover glass (for example, the cover top glass 120), and the positions of the positioning holes 121 correspond to the positions of the fixing portions 161.

As shown in fig. 5 to 7, the fixing portion 161 of the handle 160 includes a columnar body 162 and an engaging portion 163. The engaging portion 163 is disposed at the bottom end of the columnar body 162, and the engaging portion 163 extends outwards along the bottom end of the columnar body 162 to form a pair of engaging regions arranged oppositely. The engagement area is provided with two sliding guide surfaces 1631, and the two sliding guide surfaces 1631 are connected by a handle up-down fixed contact surface 1632. For example, the sliding guide surface 1631 may alternatively be a smooth concave arcuate transition surface, with the handle upper and lower fixed contact surface 1632 being a convex surface. The engaging region refers to a portion of the engaging portion 163 protruding to both sides along the columnar body 162 for engagement. The sliding guide surface 1631 is an inclined surface disposed on the upper surface of the engagement region, and is used for smoother engagement.

In an embodiment, a handle groove 1621 is further formed on the cylindrical body 162 of the fixing portion 161, and the handle groove 1621 abuts the handle upper and lower fixing contact surface 1632. The cylindrical body 162 of the fixing portion 161 is further provided with a handle horizontal contact area 1622 located at both sides of the handle groove 1621.

In another embodiment, a longitudinal groove 1633 may be formed on at least one side of the cylindrical body 162 of the fixing portion 161. For example, in this embodiment, longitudinal grooves 1633 are formed on both sides of the columnar body 162, so that the cross section of the fixing portion 161 is in an H-shaped structure 1611.

According to the inventive concept of the present application, the recess 1633 may not be disposed, may be disposed singly, or may be disposed in a plurality of ways. The recess 1633 may be formed to penetrate the columnar body 162, or may be formed to open in a partial region of the columnar body 162. That is, the number and the structure of the grooves 1633 are not limited, and can be adjusted according to the actual requirements, which are all within the scope of the present application. The recess 1633 is provided here primarily for the purpose of increased elasticity and weight reduction.

The fixing portion 161 may be made of plastic material and has a certain elasticity. In this way, when the columnar body 162 of the fixing portion 161 is pressed, the strength is increased, and meanwhile, a certain plastic deformation can be generated, so that the assembly of the fixing block 170 and the handle 160 is facilitated.

Meanwhile, due to the special H-shaped structure, the wall thickness of the plastic material is more uniform, and the shrinkage phenomenon is reduced from the molding angle of the plastic mold, so that the product quality is improved. In addition, by adjusting the thickness of the H-shaped structure intermediate reinforcing rib, the deformation and strength of the fixing portion 161 of the handle 160 can be adjusted.

In another embodiment, as shown in fig. 5, a protrusion 164, i.e. a handle touch indication protrusion, may be further provided on the side wall surface of the handle 160 for indicating the touch position. The purpose of the raised portion 164 is to enhance the touch feel, alert the customer to the touch location, and facilitate the customer's opening and closing of the hood glass (e.g., hood roof glass 120) by pushing on the handle.

As shown in fig. 8 to 10, the upper end surface of the fixing block 170 is provided with a cavity 171, and at least one group of locking structures 172 are provided on both side wall surfaces of the cavity 171, and the engagement region of the fixing portion 170 is engaged with the corresponding locking structure 172. The cavity 171 may be a single integral space or a plurality of independent small spaces for installing the locking structure 172, so that a space is formed between the locking structure 172 and the bottom of the fixing block 170, and the locking region of the fixing portion 170 can be locked.

Preferably, each set of locking structures 172 includes a pair of oppositely disposed cantilever arms Liang Kagou 173, each pair of cantilever arms Liang Kagou 173 being oppositely disposed on both side walls of the cavity 171, and forming a catch 1731 between the cantilever arms Liang Kagou 173. When the handle 160 and the fixing block 170 are locked, the columnar body 162 of the fixing portion 161 is mounted into the locking groove 1731 through the sliding guide surface 1631, the locking portion 163 is locked to the bottom of the corresponding cantilever Liang Kagou 173, and the handle up-down fixing contact surface 1632 abuts against the bottom surface of the corresponding cantilever Liang Kagou.

Here, as shown in fig. 10, the bottom end surface of the cantilever Liang Kagou 173 is a fixed block up-down locking contact surface 1732, and the fixed block up-down locking contact surface 1732 may be provided as an inclined surface.

Further, in one embodiment, a deformation avoiding space 174 is provided between the cantilever Liang Kagou 173 and the upper end surface of the fixed block 170. The end of the cantilever Liang Kagou 173 includes two horizontally oriented regions 1733 and a top 1734, the top 1734 being connected between the two horizontally oriented regions 1733. When the cylindrical body 162 of the fixing portion 160 is mounted into the latching groove 1731 through the sliding guide surface 1631, the latching hook top 1734 of the cantilever Liang Kagou 173 is latched into the handle groove 1621, and the handle horizontal contact area 1622 contacts the latching hook horizontal guide area 1733 in the horizontal direction. The locking contact surface 1732 of the fixing block up and down can slide easily along the sliding guide surface 1631 while pushing the fixing block 170 by hand so that the hook top 1734 thereof is caught in the handle groove 1621.

When the hook top 1734 is snapped into the handle recess 1621, the handle upper and lower securing contact 1632 and the securing block upper and lower locking contact 1732 contact each other. In the product design angle, a certain interference is designed in the vertical contact area of the two parts, and in combination with the illustration of fig. 14, 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, and as the upper part of the cantilever Liang Kagou is designed with a certain deformation avoiding space 174, the cantilever Liang Kagou 173 can deform upwards due to being extruded. To this end, the cantilever Liang Kagou 173 is always subjected to a vertically upward force so that the fixing block 170 and the bottom surface of the cover glass (e.g., the cover top glass 120) are always in close contact. For the handle 160, a vertical downward force is always applied so that the top surfaces of the handle 160 and the cover glass (e.g., the cover top glass 120) are always in close contact. The handle 160 and the fixing block 170 are always closely connected in the vertical direction, and the relative positions are effectively fixed.

As shown in fig. 11, the handle 160 and the cover glass (e.g., the cover top glass 120) are held such that two fixing portions 161 on the handle 160 and two positioning holes 121 on the cover glass (e.g., the cover top glass 120) are in a concentric relative position in the vertical direction, and then the fixing portions 161 of the handle 160 are inserted into the positioning holes 121. The fixing block 170 is placed right under the handle 160, and the relative position of the fixing block 170 is adjusted so that the pre-locking position (i.e. the locking structure 172) of the fixing block 170 is exactly coincident with the projection of the fixing portion 161 of the handle 160 on the fixing block 170, at this time, the fixing block 170 is pushed vertically upwards, and the fixing portion 161 of the handle 160 is located at the pre-locking position (i.e. the locking structure 172) of the fixing block 170, and the installation effect is as shown in fig. 12.

When the mounting process is in the state of fig. 12, the relevant mounting position thereof is horizontally sectioned, and the result is shown in fig. 15. It can be seen more clearly that the securing portion 161 on the handle 160 is located in the pre-lock position (i.e., the locking structure 172) of the securing block 170.

The above state is maintained, the fixing block 170 is pushed so that the fixing post 161 of the handle 160 passes over the pre-locking position of the fixing block 170, and a click is heard to reach the locking position, and the installation effect is as shown in fig. 13.

When the mounting process is in the state of fig. 13, the relevant mounting position thereof is horizontally sectioned, and the result is shown in fig. 16. It can be seen more clearly that the handle fixing post 161 on the handle 160 is already in the locked position.

According to the technical scheme, a plurality of cantilevers Liang Kagou 173 can be designed on the fixed block 170, and one cantilever is taken for illustration because the function and the structure are the same. When the fixing block 170 is pushed by hand to perform the locking function of the fixing block (i.e. in the process of fig. 12 to 13 and 15 to 16), firstly, the horizontal guiding area 1733 of the hook contacts the fixing portion 161 of the handle 160, which plays a role in sliding guiding the fixing portion 161 of the handle 160, and the fixing block 160 is pushed continuously, so that the top 1734 of the hook on the cantilever Liang Kagou 173 can be blocked into the handle groove 1621.

When the handle on the windshield glass is in the 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, and in the product design angle, the horizontal contact areas of the two parts design a certain interference. Referring to fig. 16, after being in place, a certain compression deformation is generated between the handle horizontal contact area 1622 and the hook horizontal guide area 1733, thereby generating a pair of interaction forces. The cooperation between the handle groove 1621 and the hook top 1734 effectively fixes the relative positions of the handle 160 and the fixing block 170 in the horizontal direction.

When the installation process is in the state of fig. 13, the relevant assembly position thereof is vertically and longitudinally sectioned, and the view shown in fig. 14 is obtained. As can be seen in fig. 13 and 14, the handle glass contact surface 165 on the handle 160 is in intimate contact with the upper surface of the cover glass (e.g., the cover top glass 120). The fixing block glass contact surface 175 of the fixing block 170 is in close contact with the lower surface of the cover glass (e.g., the cover top glass 120), and the fixing portion 161 of the handle 160 is already caught in the positioning hole 121 of the cover glass (e.g., the cover top glass 120), so that the relative position of the cover glass (e.g., the cover top glass 120) in the horizontal and vertical directions is effectively fixed.

As described above, the handle 160, the cover glass and the fixing block 170 are firmly and effectively fixed together, thereby completing the opening and closing functions of the cover glass door.

In summary, the balance fan housing with the handle and the electronic balance comprising the same have the following advantages:

1. the fan cover glass can be fixed through the tight connection between the clamping groove on the handle and the cantilever beam buckle on the fixed block.

2. The balance fan housing is simple in structure, easy to implement and capable of effectively reducing cost.

3. The balance fan housing optimizing structure can effectively improve efficiency and reliability.
