Description

Technical Field

[0001] The utility model belongs to the technical field of fixing brackets, and in particular relates to a pressure sensor fixing bracket. Background Art

[0002] A pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable output electrical signals according to certain rules. It is usually composed of a pressure sensitive element and a signal processing unit. The pressure sensor can convert the sensed liquid or gas pressure into a standard electrical signal for external output. It is widely used in various industrial automation environments. When the pressure sensor is used, a practical fixing frame will be used to fix the pressure sensor. Therefore, it can be seen that the existing fixing frame basically meets people's practical needs, but the following problems still exist.

[0003] When the operator applies the pressure sensor to the weight scale, the operator places two support frames on both sides of the pressure sensor respectively, and then connects the support and the pressure sensor together through bolts, so that the operator can install the pressure sensor on the support frame conveniently. However, when installing, the operator may need to place the support frame on the pressure sensor and move the support frame to align the mounting holes on the support frame with the mounting holes on the pressure sensor, so that the bolts can install the pressure sensor and the support frame to each other. However, since the operator needs to align the mounting holes on the pressure sensor and the support frame, it may be cumbersome for the operator to install the pressure sensor and the support frame. For this reason, we propose a pressure sensor support frame. Utility Model Content

[0004] The utility model provides a pressure sensor fixing frame, which drives a fixing block to be inserted into a mounting groove through a second connecting plate, connects the second connecting plate and the first connecting plate to each other, and enables a lower mounting plate and an upper mounting plate to be mounted on the surface of the pressure sensor, thereby improving the convenience of the operator in installing the pressure sensor.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pressure sensor fixing bracket, including a detection bracket, including an upper mounting plate and a lower mounting plate, wherein a first connecting plate and a second connecting plate are fixed on opposite sides of the upper mounting plate and the lower mounting plate, respectively, a mounting groove is opened in the middle of the first connecting plate, and a fixing block fixed on the second connecting plate is inserted in the middle of the mounting groove, a limiting block is fixed on one side where the second connecting plate and the first connecting plate are attached to each other, and the surface of the limiting block is provided with a limiting groove opened on the first connecting plate.

[0006] Furthermore, positioning grooves are provided around the upper mounting plate and the lower mounting plate, and positioning rods are fixed on one side of the positioning grooves that are in contact with the upper mounting plate and the lower mounting plate. The surfaces of the positioning rods are provided with slots opened on the inner walls of the slide grooves, and the surfaces of the positioning rods are wrapped with first springs that are respectively in contact with the inner walls of the slide grooves and the surfaces of the positioning rods.

[0007] Furthermore, the ends of the positioning rods are all configured to be in a circular pancake shape, and the circular pancake shape of the positioning rods matches the circular pancake-shaped groove of the slot.

[0008] Furthermore, the positioning grooves are all configured as "L"-shaped right-angle grooves.

[0009] Furthermore, the fixing blocks are all configured as trapezoidal rods, and the mounting grooves are all configured as "convex" shaped through holes, and the inner wall width of the "convex" shaped through holes of the mounting grooves matches the width of the trapezoidal rods of the fixing blocks.

[0010] Furthermore, a guide groove is formed at the end of the first connecting plate close to the upper mounting plate, and a guide plate is embedded in the guide groove. A guide rod fixed on the inner wall of the guide groove passes through the middle of the guide plate, and a second spring is wound around the surface of the guide rod and respectively abuts between the inner wall of the guide groove and the surface of the guide plate. Abutment plates that are attached to the surface of the first connecting plate are fixed at both side ends of the guide plate, and the ends of the abutment plates pass through the first connecting plate and are attached to the ends of the fixed block.

[0011] The beneficial effects of the utility model are:

[0012] 1. The pressure sensor fixing frame is provided with a second connecting plate, a fixing block, a mounting groove and a first connecting plate. When the operator takes the lower mounting plate, the lower mounting plate drives the fixing block to move through the second connecting plate, aligns the second connecting plate with the first connecting plate, and the second connecting plate drives the fixing block to be inserted into the mounting groove, so that the second connecting plate and the first connecting plate are connected to each other, which is convenient for the operator to pre-install the lower mounting plate and the upper mounting plate on the pressure sensor, thereby improving the convenience of the operator in installing the pressure sensor.

[0013] 2. The pressure sensor fixing frame is provided with a positioning slot, a slide slot, a clamping slot, a positioning rod and a first spring. When the operator pulls the positioning slot, the positioning slot pulls the positioning rod to slide in the slide slot, so that the positioning rod is moved out of the clamping slot. Then, the operator pulls the positioning slot, and the positioning slot drives the positioning rod to slide in the slide slot. When the positioning slot moves to a suitable position, the first spring restores its elastic deformation, and then pushes the positioning rod to move, so that the positioning rod is inserted into the clamping slot, fixing the position of the positioning slot, making it convenient for the operator to fix the position of the positioning slot, making it convenient for the operator to fix pressure sensors of different sizes, and increasing the range of the operator's installation of the pressure sensor.

[0022] In order to further understand the content, features and effects of the utility model, the following embodiments are listed and described in detail with reference to the accompanying drawings.

[0023] Example:

[0024] See also Figure 1 - Figure 6, a pressure sensor fixing frame, comprising an upper mounting plate 1 and a lower mounting plate 2, wherein the upper mounting plate 1 and the lower mounting plate 2 have a first connecting plate 3 and a second connecting plate 4 welded to opposite sides thereof, a mounting groove 6 is provided in the middle of the first connecting plate 3, and a fixing block 5 welded on the second connecting plate 4 is inserted in the middle of the mounting groove 6, the fixing block 5 is arranged as a trapezoidal rod, and the mounting groove 6 is arranged as a "convex" shaped through hole, the inner wall width of the "convex" shaped through hole arranged in the mounting groove 6 matches the width of the trapezoidal rod arranged in the fixing block 5, a limiting block 12 is welded on one side where the second connecting plate 4 and the first connecting plate 3 are mutually attached, and the surface of the limiting block 12 is sleeved with a limiting groove 13 arranged on the first connecting plate 3, when the operator needs to clamp the pressure sensor, the operator first places the pressure sensor on the upper mounting plate 1, and places the pressure sensor in the positioning groove 11, and then the operator takes the lower mounting plate 2, and the lower mounting plate 2 drives the second connecting plate 4 to move. When the second connecting plate 4 moves, the second connecting plate 4 drives the fixing block 5 to move, and the fixing block 5 is horizontally aligned with the mounting groove 6. Then, the operator pushes the lower mounting plate 2, and the lower mounting plate 2 drives the fixing block 5 to move horizontally through the second connecting plate 4, so that the fixing block 5 is inserted into the mounting groove 6. When the fixing block 5 is inserted into the mounting groove 6, the operator pushes the lower mounting plate 2, and the lower mounting plate 2 drives the fixing block 5 to move up and down in the mounting groove 6 through the second connecting plate 4, so that the end of the fixing block 5 and the inner wall of the mounting groove 6 are in contact with each other, and when the second connecting plate 4 moves, the second connecting plate 4 drives the limiting block 12 to be inserted into the limiting groove 13, and the second connecting plate 4 and the first connecting plate 3 are connected to each other, so that the upper mounting plate 1 and the lower mounting plate 2 are pre-installed on the pressure sensor, so as to facilitate the alignment of the mounting holes opened on the pressure sensor and the mounting holes opened on the surfaces of the lower mounting plate 2 and the upper mounting plate 1, thereby improving the convenience of installation by the operator.

[0025] In other embodiments, the upper mounting plate 1 and the lower mounting plate 2 are all provided with positioning grooves 11 around them, and the positioning grooves 11 are welded with positioning rods 8 on one side that is in contact with the upper mounting plate 1 and the lower mounting plate 2. The surfaces of the positioning rods 8 are sleeved with card slots 9 provided on the inner wall of the slide groove 10, and the surfaces of the positioning rods 8 are wound with first springs 7 respectively abutting between the inner wall of the slide groove 10 and the surfaces of the positioning rods 8. When the operator needs to adjust the position of the positioning grooves 11, the operator first pulls the positioning grooves 11, and the positioning grooves 11 drive the positioning rods 8 to move up and down in the slide grooves 10, and move the positioning rods 8 out of the card slots 9. When the positioning rods 8 move up and down, the positioning rods 8 squeeze the first springs 7, causing the first springs 7 to undergo elastic deformation. After the first spring 7 undergoes elastic deformation, the first spring 7 avoids the positioning rod 8. When the positioning rod 8 moves out of the slot 9, the operator pulls the positioning slot 11, and the positioning slot 11 drives the positioning rod 8 to slide left and right in the slide slot 10, so that the positioning slot 11 slides on the surfaces of the upper mounting plate 1 and the lower mounting plate 2. When the positioning slot 11 moves to a suitable position, the operator releases the first spring 7, and the elastic deformation of the first spring 7 is restored. The first spring 7 pushes the positioning rod 8 to move, so that the positioning rod 8 is inserted into the slot 9, and the position of the positioning rod 8 is fixed, thereby fixing the position of the positioning slot 11, making it convenient for the operator to clamp pressure sensors of different sizes, and improving the operator's ability to clamp pressure sensors of different sizes.

[0026] In other embodiments, the ends of the positioning rod 8 are all configured to be round cake shapes, and the round cake shapes of the positioning rod 8 match the round cake-shaped grooves of the card slot 9. By matching the round cake shapes of the positioning rod 8 with the round cake-shaped grooves of the card slot 9, the round cake shapes of the positioning rod 8 can be inserted into the card slot 9. The card slot 9 accommodates the positioning rod 8, thereby improving the stability of the positioning rod 8 installed in the card slot 9.

[0027] In other embodiments, the positioning grooves 11 are all configured as "L"-shaped right-angle grooves. By configuring the positioning grooves 11 as "L"-shaped right-angle grooves, the positioning grooves 11 are convenient for supporting the pressure sensor around, thereby improving the stability of the pressure sensor placed on the upper mounting plate 1 and the lower mounting plate 2.

[0028] In other embodiments, the first connecting plate 3 is provided with a guide groove 17 at the end portion near the upper mounting plate 1, and the guide groove 17 is embedded with the guide plate 14, and the middle portion of the guide plate 14 is penetrated by a guide rod 16 welded on the inner wall of the guide groove 17, and the surface of the guide rod 16 is wound with a second spring 15 respectively abutting between the inner wall of the guide groove 17 and the surface of the guide plate 14, and the two side ends of the guide plate 14 are welded with abutment plates 18 abutting on the surface of the first connecting plate 3, and the end of the abutment plate 18 penetrates the first connecting plate 3 and abuts on the end of the fixing block 5. When the operator inserts the fixing block 5 into the mounting groove 6, the operator first pulls the abutment plate 18, and the abutment plate 18 drives the guide plate 14 to slide in the guide groove 17, and when the guide plate 14 slides in the guide groove 17, the circular through hole in the middle portion of the guide plate 14 slides on the surface of the guide rod 16, and when the guide plate 14 slides on the surface of the guide rod 16, the guide rod 16 pulls the guide plate 14, which is convenient for the guide plate 1 4 slides in the guide groove 17 to improve the stability of the guide plate 14 in moving. When the guide plate 14 slides in the guide groove 17, the guide plate 14 presses the second spring 15 to make the second spring 15 elastically deformed. After the second spring 15 is elastically deformed, the second spring 15 avoids the guide plate 14, so that the push plate 18 slides on the surface of the first connecting plate 3. The push plate 18 moves in the notches opened on the side walls of both sides of the first connecting plate 3, so that the push plate 18 moves away from the surface of the fixed block 5. Then, the operator lifts the lower mounting plate 2 upward, the lower mounting plate 2 drives the second connecting plate 4 to move, and the second connecting plate 4 drives the fixed block 5 to move, so that the fixed block 5 moves out of the mounting groove 6, which is convenient for the operator to disassemble the second connecting plate 4 and the first connecting plate 3. When the fixed block 5 is inserted into the mounting groove 6, the push plate 18 is clamped on the surface of the fixed block 5, so that the push plate 18 presses the fixed block 5, thereby improving the stability of the fixed block 5 installed in the mounting groove 6.
