[0002] The pre-tightening device is used to assist in installing electronic components onto the mounting plate inside the electric control cabinet. The pre-tightening device consists of a mounting plate fixed to the inner wall of the electric control cabinet, a slideway, a sliding plate, and an airbag. When assisting in installing electronic components, the electronic components are clamped onto the mounting plate, the electronic components are horizontally and vertically aligned with the mounting groove on the inner wall of the electric control cabinet, then the sliding plate in the slideway is slid to the position of the electronic components, an air pump is connected to the airbag nozzle for inflation, so that the airbag bulges to pre-tighten the electronic components, and then the worker screws the screw into the installation groove to complete the fixation of the electronic components.

[0003] The inventor found in daily work that when the pre-tightening device is in use, since the pre-tightening of the electronic components is limited by the inflation of the airbag, the airbag needs to be inflated by an air pump to bulge and squeeze the electronic components for limitation. When the air pump inflates the airbag, the output end of the air pump needs to be connected to the airbag. After the electronic components are fixed, the air pump needs to be connected to the airbag again for suction to recover the airbag for the next use, which leads to a cumbersome pre-tightening process for the electronic components. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that in the actual use process, since the pre-tightening of the electronic components is limited by the inflation of the airbag, the airbag needs to be inflated by an air pump to bulge and squeeze the electronic components for limitation. When the air pump inflates the airbag, the output end of the air pump needs to be connected to the airbag. After the electronic components are fixed, the air pump needs to be connected to the airbag again for suction to recover the airbag for the next use, which leads to a cumbersome pre-tightening process for the electronic components, and to propose an assembly pre-tightening device for electrical components.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: An assembly pre-tightening device for electrical components, including a mounting plate, a slideway is opened on the front surface of the mounting plate, a sliding plate is slidably connected to the inner wall of the slideway, an airbag and a fixing component are arranged on the front surface of the sliding plate, a gas inflation component is arranged on the inner wall of the airbag, the gas inflation component includes an inflation chamber and an air inlet chamber arranged inside the airbag, an inflation mechanism is arranged on the inner wall of the inflation chamber, the air inlet chamber intakes air by means of the inflation mechanism, and an air nozzle is installed on the front surface of the airbag.

[0006] The effects achieved by the above components are as follows: By setting up the air-blowing assembly, when it is necessary to pre-tighten the electronic components, the slide plate is pushed to slide on the slideway and then slides between the electronic components and the installation. Through the air-blowing mechanism, gas enters the air inlet cavity through the air-blowing cavity, causing the airbag to bulge and squeezing the electronic components for positioning. After fixing the electronic components, press the valve core in the air nozzle to make the gas in the air inlet cavity escape, causing the airbag to deflate, and then it is used to pre-tighten the next electronic component, thus achieving the effect of facilitating the pre-tightening of the electronic components.

[0007] Preferably, the air-blowing mechanism includes a check valve one installed at the left end of the airbag, and a check valve two is installed on the right side inner wall of the air-blowing cavity.

[0008] The effects achieved by the above components are as follows: Press the airbag in the part of the air-blowing cavity, so that the gas in the air inlet cavity enters the air inlet cavity through the check valve two. The check valve two allows the gas in the air-blowing cavity to flow into the air inlet cavity, otherwise it cannot flow in. The check valve one allows the outside gas to flow into the air-blowing cavity, and conversely, the gas in the air-blowing cavity cannot flow out to the outside.

[0009] Preferably, a spring and a telescopic rod are fixedly connected to the bottom inner wall of the air-blowing cavity, and the other end of the spring is fixed to the top inner wall of the air-blowing cavity.

[0010] The effects achieved by the above components are as follows: By setting the spring, the air-blowing cavity after being pressed is reset.

[0011] Preferably, the spring is sleeved on the surface of the telescopic rod, and the other end of the telescopic rod is fixed to the top inner wall of the air-blowing cavity.

[0012] The effects achieved by the above components are as follows: By setting the telescopic rod, the spring is limited.

[0013] Preferably, a protective block is fixedly connected to the front surface of the airbag, and the protective block is a rubber block.

[0014] The effects achieved by the above components are as follows: By setting the protective block, the direct contact between the electronic components and the airbag is avoided.

[0015] Preferably, the fixing assembly includes elastic bands one fixedly connected to the left and right sides of the slide plate, and a magic tape one is fixedly connected to the surface of the elastic band one.

[0016] The effects achieved by the above components are as follows: When fixing the airbag to the slide plate, the elastic bands one on both sides are fixed together through the magic tape one, and thus tied to the airbag for positioning, so as to fix the airbag to the slide plate.

[0017] Preferably, elastic bands two are fixedly connected to the upper and lower sides of the slide plate, and a magic tape two is fixedly connected to the surface of the elastic band two.

[0018] The effects achieved by the above components are as follows: By setting the second elastic band and the second magic tape, the auxiliary airbag is fixed to the skateboard.

[0019] In summary, the beneficial effects of the present utility model are as follows:

[0020] In the present utility model, by setting the air inflation assembly, when it is necessary to pre-tighten the electronic components, the skateboard is pushed to slide on the slideway, and then it slides between the electronic components and the installation. Through the air inflation mechanism, the gas enters the air inlet cavity through the air inflation cavity, causing the airbag to bulge and squeezing the electronic components for positioning. After the electronic components are fixed, the valve core in the air nozzle is pressed, so that the gas in the air inlet cavity escapes, causing the airbag to deflate, and then it is used to pre-tighten the next electronic component, thereby achieving the effect of facilitating the pre-tightening of the electronic components, and solving the problem that since the pre-tightening of the electronic components is achieved by the airbag bulging to limit it, and the airbag needs to be inflated by an air pump to bulge and squeeze the electronic components for positioning. When the air pump inflates the airbag, the output end of the air pump needs to be connected to the airbag. After the electronic components are fixed, the air pump needs to be connected to the airbag again for suction to recover the airbag for the next use, resulting in a cumbersome process for pre-tightening the electronic components.

[0026] Referring to Figure 1 as shown, the present utility model provides a technical solution: An assembly pre-tightening device for electrical components includes an installation plate 1. A slideway 4 is opened on the front surface of the installation plate 1. The inner wall of the slideway 4 is slidably connected with a skateboard 6. An airbag 5 and a fixing component 3 are arranged on the front surface of the skateboard 6. An air inflation component 2 is arranged on the inner wall of the airbag 5.

[0027] Specifically described below are the specific settings and functions of the air inflation component 2 and the fixing component 3.

[0028] Referring to Figure 2 and Figure 3 as well as Figure 4 shown, in this embodiment: The air inflation component 2 includes an air inflation chamber 21 and an air intake chamber 22 arranged inside the airbag 5. The inner wall of the air inflation chamber 21 is provided with an air inflation mechanism 23. The air intake chamber 22 intakes air by means of the air inflation mechanism 23. An air nozzle 25 is installed on the front surface of the airbag 5. By setting the air inflation component 2, when it is necessary to pre-tighten the electronic components, the sliding plate 6 is pushed to slide on the slideway 4, and then it slides between the electronic components and the installation. Through the air inflation mechanism 23, gas enters the air intake chamber 22 through the air inflation chamber 21, causing the airbag 5 to bulge and squeezing the electronic components for limiting. After the electronic components are fixed, the valve core in the air nozzle 25 is pressed, so that the gas in the air intake chamber 22 escapes, causing the airbag 5 to deflate, and then it is used to pre-tighten the next electronic component, thereby achieving the effect of facilitating the pre-tightening of the electronic components. The air inflation mechanism 23 includes a check valve one 231 installed at the left end of the airbag 5, and a check valve two 232 is installed on the right side of the inner wall of the air inflation chamber 21. Press the airbag 5 in the part of the air inflation chamber 21, so that the gas in the air intake chamber 22 enters the air intake chamber 22 through the check valve two 232. The check valve two 232 enables the gas in the air inflation chamber 21 to flow into the air intake chamber 22, and vice versa, it cannot flow in. The check valve one 231 allows the outside gas to flow into the air inflation chamber 21, and vice versa, the gas in the air inflation chamber 21 cannot flow out to the outside. The bottom of the inner wall of the air inflation chamber 21 is fixedly connected with a spring 233 and a telescopic rod 234. The other end of the spring 233 is fixed to the top of the inner wall of the air inflation chamber 21. By setting the spring 233, the air inflation chamber 21 after being pressed is reset. The spring 233 is sleeved on the surface of the telescopic rod 234. The other end of the telescopic rod 234 is fixed to the top of the inner wall of the air inflation chamber 21. By setting the telescopic rod 234, the spring 233 is limited. A protective block 24 is fixedly connected to the front surface of the airbag 5. The protective block 24 is a rubber block. By setting the protective block 24, direct contact between the electronic components and the airbag 5 is avoided.

[0029] Referring to Figure 2 shown, in this embodiment: The fixing component 3 includes elastic bands one 31 fixedly connected to the left and right sides of the sliding plate 6. A magic tape one 32 is fixedly connected to the surface of the elastic band one 31. When fixing the airbag 5 to the sliding plate 6, the elastic bands one 31 on both sides are fixed together through the magic tape one 32, and thus are tied to the airbag 5 for limiting, thereby fixing the airbag 5 to the sliding plate 6. Elastic bands two 33 are fixedly connected to the upper and lower sides of the sliding plate 6. A magic tape two 34 is fixedly connected to the surface of the elastic band two 33. By setting the elastic bands two 33 and the magic tape two 34, the airbag 5 is assisted to be fixed to the sliding plate 6.

[0030] Working principle:

[0031] When assisting in the installation of electronic components, the electronic components are clamped onto the mounting plate 1. The electronic components are horizontally and vertically aligned with the mounting slots on the inner wall of the electric control cabinet. Then, the slide plate 6 in the slideway 4 is slid to the position of the electronic components. An air pump is connected to the airbag 5 nozzle for inflation. As a result, the airbag 5 bulges to pre-tighten the electronic components. Then, the worker screws the screwdriver into the mounting slot to complete the fixation of the electronic components. When pre-tightening the electronic components is required, the slide plate 6 is pushed to slide on the slideway 4 and then slides between the electronic components and the mounting. Through the air inflation mechanism 23, the gas enters the air inlet cavity 22 through the air inflation cavity 21, causing the airbag 5 to bulge and squeeze the electronic components for limiting. After fixing the electronic components, the valve core in the air nozzle 25 is pressed, causing the gas in the air inlet cavity 22 to escape, making the airbag 5 deflate, and then it is used to pre-tighten the next electronic component, thus achieving the effect of facilitating the pre-tightening of electronic components. Pressing the airbag 5 in the part of the air inflation cavity 21 causes the gas in the air inlet cavity 22 to enter the air inlet cavity 22 through the check valve II 232. The check valve II 232 allows the gas in the air inflation cavity 21 to flow into the air inlet cavity 22, and vice versa, it cannot flow in. The check valve I 231 allows the outside gas to flow into the air inflation cavity 21, and vice versa, the gas in the air inflation cavity 21 cannot flow out to the outside. By setting the spring 233, the air inflation cavity 21 after being pressed is reset. By setting the telescopic rod 234, the spring 233 is limited. By setting the protective block 24, direct contact between the electronic components and the airbag 5 is avoided. When fixing the airbag 5 to the slide plate 6, the elastic bands I 31 on both sides are fixed together through the magic tape I 32 and then tied to the airbag 5 for limiting, thus fixing the airbag 5 to the slide plate 6. By setting the elastic band II 33 and the magic tape II 34, the airbag 5 is assisted in being fixed to the slide plate 6.
