Description

Technical Field

[0001] The utility model relates to a tooling accessory, in particular to a protective device for a truck scale sensor. Background Art

[0002] Truck scales, also known as floor scales, are used to measure the tonnage of a truck's cargo. They are the main weighing equipment used for bulk cargo measurement in factories, mines, transportation, port logistics, etc. The working principle is as follows: When the cargo enters the weighing platform, the elastic body of the weighing sensor undergoes elastic deformation under the action of the cargo's gravity, causing the bridge impedance of the strain gauge attached to the elastic body to lose balance, and outputs an electrical signal proportional to the weight value. The digital signal is processed by the amplifier, A / D converter, microprocessor and other electronic components inside the sensor, and then enters the weighing display instrument through a repeater to directly display the weight and other data. It can be seen from this that the truck scale sensor is a key component. If any one of them is tilted, the load balance between the weighing sensors will be broken, resulting in incorrect weighing data. In actual production operations, the truck scale sensor is exposed to the outside for a long time. In order to prevent dust and dirt from accumulating and covering the sensor and external forces from affecting the accuracy of the weighing data, a protective baffle should be set up around the truck scale sensor. For example, the protective baffle disclosed in "Truck Scale Sensor Protective Baffle Device" (CN201320562962.7) is fixed to the scale body by connecting fixing bolts.

[0003] However, in order to ensure the high weighing accuracy of the sensor, the sensor needs to be inspected or maintained, and the fixing bolts must be removed for each operation; and if the bolts are used for a long time, they are prone to rust, and they are easy to break when removed, resulting in the side cover being unable to be installed normally.

[0004] Therefore, there is an urgent need for a reliable and easy-to-use vehicle scale sensor protection device. Utility Model Content

[0005] The technical task of the utility model is to provide a vehicle scale sensor protection device in view of the above deficiencies in the prior art, which makes inspection or maintenance more convenient and quicker through the sliding installation and removal of the baffle.

[0006] The technical solution of the utility model to solve its technical problems is: a protective device for a vehicle scale sensor, including side baffles and a front baffle, characterized in that it also includes a top rail, a bottom support and a transverse slide groove; the top rails are two and fixedly installed on both sides of the scale body above the sensor; the inner side of the upper end of the side baffle is provided with an inner slide groove corresponding to the top rail, the bottom support is concave and is located below the side baffle; the bottom of the side baffle is inserted into the upper opening of the bottom support but does not contact the bottom of the bottom support; a transverse slide groove is provided on the outer side of the base of the sensor, the bottom of the front baffle is embedded in the transverse slide groove, and the two are slidably connected; one end of the transverse slide groove is closed and the other end is open, the length of the transverse slide groove is greater than the width of the front baffle, and the open end is connected with a movable stopper.

[0007] Furthermore, the top rail is a T-shaped rail.

[0008] Furthermore, the base is connected to the base of the sensor.

[0009] Furthermore, the width of the front baffle is greater than the distance between the outer walls of the baffles on both sides.

[0010] Furthermore, the bottom end of the side baffle is not lower than the top end of the transverse slide groove.

[0011] Furthermore, the bottom end of the side baffle is flush with the top end of the transverse slide groove.

[0012] In one implementation, the movable stopper is an L-shaped pin, and a pin hole is provided at the bottom of the transverse slide groove at a position relative to the side wall of the positive baffle.

[0025] like Figure 1 As shown, the utility model is a vehicle scale sensor protection device.

[0026] It includes side baffles 3, a front baffle 7, a top rail 1, a bottom support 6 and a transverse slide 9.

[0027] There are two top rails 1, which are fixedly installed on both sides of the scale body 2 above the sensor 4. In the optimization scheme, in order to increase stability, the top rails 1 are T-shaped rails.

[0028] The inner side of the upper end of the side baffle 3 has an inner slide groove corresponding to the top rail 1, and the bottom bracket 6 is concave, located below the side baffle 3, and connected to the base 5 of the sensor 4. During installation, the inner slide groove of the side baffle 3 is aligned with the top rail 1 and inserted, and the bottom is inserted into the upper opening of the bottom bracket 6, but does not contact the bottom of the bottom bracket 6. The upper and lower cooperation can realize the installation, insertion and removal of the side baffle 3.

[0029] A transverse slide groove 9 is provided on the outside of the base 5 of the sensor 4, and the bottom of the positive baffle 7 is embedded in the transverse slide groove 9, and the two are slidably connected. One end of the transverse slide groove 9 is closed and the other end is open. The length of the transverse slide groove 9 is greater than the width of the positive baffle 7, and a movable stop is connected to the open end.

[0030] In Example 1, the movable baffle is an L-shaped pin 8, and a pin hole is provided at the bottom of the transverse slide groove 9 relative to the side wall of the positive baffle 7. When the positive baffle 7 slides to the right to the end, the L-shaped pin 8 is inserted into the pin hole to achieve the limited fixation of the positive baffle 7. Since the width of the positive baffle 7 is greater than the distance between the outer walls of the baffles 3 on both sides, the fixation of the positive baffle 7 achieves the fixation of the side baffles 3.

[0031] In the second embodiment, the movable baffle is a movable baffle 11. The bottom of the movable baffle 11 is hinged to the bottom of the open end of the horizontal slide groove 9. The movable baffle 11 is wider than the side wall of the positive baffle 7. There are two pin holes 10 on the movable baffle 11. The side wall of the positive baffle 7 and the left side baffle 3 are also provided with pin holes at corresponding positions. After the movable baffle 11 is folded upward, the pins are inserted into the pin holes 10 to fix the side wall of the positive baffle 7 and the left side baffle 3.

[0032] The bottom end of the side baffle 3 is not lower than the top end of the transverse chute 9, and the transverse chute 9 does not hinder the sliding of the side baffle 3. In the optimization scheme, the bottom end of the side baffle 3 is flush with the top end of the transverse chute 9.

[0033] It should be noted that matters not described in detail in this embodiment are well-known technologies in the art.

[0034] The above description is only for the purpose of describing the present invention in detail for the specific implementation purpose of the present invention.
