Description
Technical Field
[0001] The present application relates to the technical field of measuring equipment, and in particular to a windshield for a balance. Background Art
[0002] Currently, the balances on the market, especially in the cosmetics field, generally have built-in high-precision mass sensors to ensure measurement accuracy. In order to reduce the interference of external wind volume and cause measurement errors, a wind shield is generally installed on the balance to reduce the impact of wind volume on measurement accuracy.
[0003] In order to facilitate observation, the existing windshield is generally made of transparent materials such as glass, and a sliding door is provided on the windshield. The windshield can be opened and closed by pushing the sliding door, so that the items can be taken and placed.
[0004] With regard to the above-mentioned related technologies, when the sliding door is opening and closing, the friction between the door body and the track will cause vibration, which may affect the measurement results of the balance; at the same time, in order to prevent the friction from driving the balance to move, additional auxiliary fixing cover or balance is generally required when opening and closing the door; therefore, the existing opening method of the sliding door is inconvenient to use and may affect the measurement accuracy of the balance. Utility Model Content
[0005] In order to reduce the impact of opening and closing the door on the measurement accuracy of the balance, the present application provides a wind shield for the balance.
[0006] The present application provides a windshield for a balance, which adopts the following technical solution:
[0007] A windshield for a balance comprises a support frame arranged on the balance, a windshield plate arranged on the support frame, and a switch door hinged on the support frame. The support frame, the windshield plate, the switch door and the balance together form a storage space for placing a measured object.
[0008] By adopting the above technical scheme, the wind shield forms a storage space for placing the measured object through the arrangement of the supporting frame, the wind shield and the switch door, thereby effectively blocking the interference of external wind force; since the switch door is installed in a hinged manner, when the switch door is opened and closed, the rotation of the switch door is relatively stable, and the friction between the switch door and the supporting frame is small, so it should not cause the balance to vibrate, that is, it can reduce the influence of the switch door on the measurement accuracy of the balance.
[0009] Optionally, the switch door is respectively arranged above and on the left and right sides of the support frame, and the support frame is provided with a limit member for limiting the opening of the switch door in a natural state.
[0010] By adopting the above technical solution, switch doors are set on the top and left and right sides of the supporting frame, which is convenient for placing and removing the measured objects in different directions; at the same time, the setting of the limiter can limit the opening of the switch door in a natural state, avoiding the switch door being blown open by the wind when not in use, affecting the windproof effect.
[0011] Optionally, the support frame is provided with a stepped groove for accommodating the switch door, and the switch door is rotatably connected to the support frame via a hinge.
[0012] By adopting the above technical solution, the setting of the step groove enables the switch door to be more stably rotated and connected to the support frame. At the same time, the switch door is located in the step groove, which can further increase the windproof effect.
[0013] Optionally, the limiting member includes an iron sheet arranged on the supporting frame and a magnetic sheet arranged on the switch door, and the iron sheet is arranged on the bottom wall of the step groove. When no external force is applied, the magnetic sheet and the iron sheet are magnetically attracted to each other.
[0014] By adopting the above technical solution, the automatic closing of the switch door is achieved through the mutual magnetic attraction between the iron sheet and the magnetic sheet; when the switch door is close to the iron sheet, the magnetic sheet will be attracted and fit tightly with the iron sheet, thereby achieving automatic closing of the switch door; this design not only simplifies the operating steps, but also improves the windproof effect of the wind shield.
[0015] Optionally, the support frame is provided with a sealing strip circumferentially on the stepped groove, the iron sheet is embedded in the sealing strip, and the magnetic sheet is embedded on the switch door.
[0016] By adopting the above technical solution, the provision of the sealing strip enhances the sealing performance of the windshield, and effectively prevents external airflow from entering the interior of the windshield through the gap.
[0017] Optionally, the support frame is detachably mounted on the balance, a fixing member for fixing the support frame on the balance is provided on the support frame, and a positioning groove for inserting the support frame is circumferentially provided on the balance.
[0018] By adopting the above technical solution, the design of the fixing parts and the positioning grooves enables the support frame to be stably fixed on the balance and is not easy to shake or fall off; at the same time, when measuring objects with lower accuracy requirements, the wind shield can be removed to facilitate improving measurement efficiency.
[0019] Optionally, arc-shaped strips are provided on the side walls on both sides of the positioning groove, and the support frame can be inserted into the positioning groove with interference fit.
[0020] By adopting the above technical solution, the arc strips arranged on the side walls of the positioning groove can achieve interference insertion of the support frame, making the connection between the support frame and the balance tighter and more secure. This design enhances the overall stability of the windshield and improves its windproof effect.
[0021] Optionally, the fixing member includes a fixing rod arranged below the supporting frame, and a fixing bolt threadedly connected to the fixing rod. A fixing groove for inserting the fixing rod is provided on the balance, and the fixing bolt can pass through the side wall of the balance and be threadedly connected to the fixing rod.
[0022] By adopting the above technical solution, the cooperation between the fixing rod and the fixing bolt makes the fixing process simpler and more convenient, and also improves the stability of the windshield.
[0023] Optionally, a damping rod is provided between the support frame and the switch door, and two ends of the damping rod are respectively hinged to the support frame and the switch door.
[0024] By adopting the above technical solution, the setting of the damping rod makes the door have a buffering effect when closing, avoiding vibration caused by violent closing; at the same time, the damping rod can also effectively reduce the shaking of the door under the action of wind, thereby improving the windproof effect and service life of the wind shield.
[0025] In summary, the present application includes at least one of the following beneficial effects:
[0026] 1. Since the present invention adopts a hinged manner to set the switch door, the friction between the switch door and the support frame can be reduced when opening and closing the switch door, thereby reducing the impact on the measurement accuracy of the ground balance;
[0027] 2. The present invention is provided with a sealing strip and a limiter, thereby further improving the windproof effect of the door in a natural state; at the same time, this magnetic attraction method also makes it easy for users to open the door, thereby improving the convenience of use;
[0028] 3. The present invention further preferably adopts the setting of a damping rod, so that the door has a buffering effect when closing, avoiding vibration caused by violent closing. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is combined with Figure 1-4 This application is described in further detail.
[0035] Embodiment 1:
[0036] The present application embodiment discloses a windshield for a balance. Figure 1 The windshield includes a supporting frame 1 arranged above the balance, a windshield 2 embedded in the supporting frame 1, and a switch door 3 hinged on the supporting frame 1. The supporting frame 1, the windshield 2 and the switch door 3 together form a storage space 4 for placing the measured object, that is, the supporting frame 1, the windshield 2 and the switch door 3 can jointly close the space above the balance to block external wind force and ensure that the balance measurement is not disturbed; at the same time, the switch door 3 is connected by a hinged manner, so that the switch door 3 is rotated and opened along the corresponding axis, and the running trajectory is smoother and more stable, and the friction between the supporting frame 1 can be greatly reduced, thereby reducing the vibration caused by the switch door 3 and reducing the influence on the measurement accuracy when the balance measures objects.
[0037] The support frame 1 is made of high-strength materials, such as aluminum alloy, stainless steel, etc., to ensure its stability; the wind shield 2 and the switch door 3 are preferably made of glass, and in other embodiments they can also be made of transparent materials such as acrylic to facilitate observation of the balance measurement; the switch door 3 can be arranged above the support frame 1 and on the left and right sides of the support frame 1, so as to facilitate the placement of measurement objects at multiple angles; in order to facilitate the rotation of the switch door 3, a handle is fixed on the side wall of all the switch doors 3 facing away from the storage space 4.
[0038] Reference Figure 1 and Figure 2In this embodiment, a step groove 11 for accommodating the switch door 3 is provided on the support frame 1. Corresponding to the position of the switch door 3, the step groove 11 is provided on the upper surface of the support frame 1 and on the left and right side surfaces. The step groove 11 is in the shape of a "U". When the switch door 3 is covered on the support frame 1, the switch door 3 can be completely sunk into the step groove 11. Preferably, the surface of the switch door 3 and the surface of the support frame 1 are located on the same plane, thereby improving the airtightness between the switch door 3 and the support frame 1. The switch door 3 and the support frame 1 can be connected by a hinge, wherein half of the hinge is fixed to the surface of the support frame 1, and the other half is fixed to the side wall of the switch door 3 away from the storage space 4. If the switch door 3 is made of glass, an opening for installation can be pre-opened when the hinge is fixed.
[0039] Reference Figure 1 and Figure 2 In the present embodiment, further, in order to limit the opening of the switch door 3 in a natural state, a limit member 5 is provided on the support frame 1, and the limit member 5 includes an iron sheet 52 and a magnetic sheet 51. The iron sheet 52 is fixed on the bottom wall of the step groove 11 of the support frame 1, and the magnetic sheet 51 is embedded in the switch door 3. On each switch door 3, the limit member 5 can be respectively provided at both ends. When no external force is applied, the magnetic sheet 51 and the iron sheet 52 are magnetically attracted to each other, thereby maintaining the closed state of the switch door 3; when the switch door 3 is opened by the handle, a certain force is applied to separate the magnetic sheet 51 and the magnet, and it should be noted that the force at this time will not cause the wind shield to shake; this design not only enhances the windproof effect, but also improves the convenience of use.
[0040] Reference Figure 1 and Figure 2 Furthermore, in an optional embodiment, in order to further improve the sealing performance of the windshield, the support frame 1 can also fix a sealing strip 12 on the surface of the step groove 11. The sealing strip 12 corresponds to the step groove 11 being in a "U" shape. The sealing strip 12 can be made of elastic materials such as rubber, and preferably, the surface of the sealing strip 12 can also be set to be wavy, so that the windproof effect can be further improved by squeezing the sealing strip 12. Correspondingly, the magnetic sheet 51 can be embedded in the sealing strip 12, and the magnetic sheet 51 can be embedded on the switch door 3.
[0041] Reference Figure 2 and Figure 3 In an optional embodiment, in order to facilitate the use of the balance under different requirements, the wind shield can be set in a detachable and fixed manner. Specifically, a positioning groove for the lower end of the support frame 1 to be inserted can be provided on the upper surface of the balance, and the positioning groove is also in the shape of a "U". The support frame 1 is also provided with a fixing member 6 for fixing the support frame 1 to the balance.
[0042] Reference Figure 2 and Figure 3 The fixing member 6 includes a fixing rod 62 and a fixing bolt 61, wherein a plurality of fixing rods 62 are fixedly arranged on the lower surface of the supporting frame 1, and a fixing groove for the fixing rod 62 to be inserted is correspondingly opened on the balance, and the fixing grooves are all located in the positioning grooves. The fixing bolt 61 can pass through the side wall of the balance and be threadedly connected with the fixing rod 62, so that the supporting frame 1 can be detachably fixed to the balance, wherein the fixing bolt 61 is preferably a countersunk thread.
[0043] Reference Figure 2 and Figure 3 Furthermore, arc-shaped strips can be fixed on the side walls on both sides of the positioning groove. The arc-shaped strips are made of elastic materials such as rubber. The support frame 1 can be inserted into the positioning groove with interference fit, so that the arc-shaped strip is deformed under the action of the support frame 1, thereby improving the stability of the windshield; or the support frame 1 can also cooperate with the rubber sleeve to open an arc-shaped groove. At this time, the arc-shaped strip can be stuck in the groove, and the arc-shaped strip is also in a compressed and deformed state.
[0044] The implementation principle of a wind shield for a balance in an embodiment of the present application is as follows: when using the balance, one only needs to rotate and open the switch door 3 to place the object to be measured on the balance for measurement; when opening and closing the switch door 3, the influence of vibration on the measurement accuracy of the balance can be eliminated due to the rotating connection method, as well as the cooperation of the sealing strip 12 and the damping rod 7; when the object to be measured has a lower accuracy requirement, the fixing bolt 61 can be unlocked and the wind shield can be removed.
[0045] Embodiment 2:
[0046] In this embodiment, based on the embodiment 1, a damping rod 7 is further provided between the switch door 3 and the support frame 1. Figure 4 The two ends of the damping rod 7 are respectively hinged on the support frame 1 and the switch door 3, which is used to slow down the opening and closing speed of the switch door 3 to prevent the balance or the wind shield from being damaged due to excessive force by the user. For the specific installation method, taking the switch door 3 located at the top as an example, one end of the damping rod 7 is hinged on the upper surface of the support frame 1, and the other end is hinged on the switch door 3, so that when the switch door 3 is closed, the damping rod 7 can play a buffering role. Correspondingly, the switch doors 3 located on the left and right sides of the support frame 1 are also respectively installed with damping rods 7. The specific structure of the damping rod 7 is the existing technology and will not be described in detail here.
[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
