Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof membrane testing equipment, and more specifically to an explosion-proof membrane testing device. Background Art

[0002] In layman's terms, explosion-proof film adds a layer of protection to car glass. When a collision occurs with the outside world, it prevents the glass from shattering and fixes broken glass slag, thereby protecting the personal safety of the car owner in the car. In the prior art, explosion-proof film needs to be tested for safety before it is sold after production, but the current testing device is not convenient for quickly pressing and fixing the explosion-proof film, and the explosion-proof film cannot be rotated and adjusted as needed, which makes it inconvenient to test explosion-proof film in different positions.

[0003] For example, the Chinese utility model with application number 202123291462.8 proposes an easy-to-adjust test device for automobile explosion-proof membrane. The patent first places the explosion-proof membrane in two hole bodies, rotates the knob, and the inner shaft rotates. The external thread and screw groove can be used to move the clamping block down, so that the clamping pad can clamp and fix the explosion-proof membrane. Pushing the holding rod can move the guide plate, the spacer, the long plug rod and the short plug rod. The guide plate stretches the spring until the long plug rod and the short plug rod move out of the rod groove. At this time, the frame can be rotated and adjusted, and then the fixed explosion-proof membrane can be rotated and adjusted. However, when fixing the explosion-proof membrane, the patent needs to pass through a hole body first, and then place the explosion-proof membrane in another hole body. Since the explosion-proof membrane is made of a soft material, wrinkles are prone to appear when passing through the first hole body, which affects the test results of the explosion-proof membrane.

[0004] Therefore, the utility model provides an explosion-proof membrane testing device. Utility Model Content

[0005] The utility model aims to solve the technical problems raised by the above-mentioned background technology, and provides an explosion-proof film testing device. The roller can prevent the explosion-proof film from wrinkling when it is moved, and the moving block and the moving plate can fix the explosion-proof film.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an explosion-proof membrane testing device, comprising a base, a first fixing member is connected to the left side of the top of the base, a second fixing member is connected to the right side of the top of the base, the front and rear side walls of the first fixing member and the second fixing member are both connected to a first screw rod, the first screw rod is connected to a moving block, the tops of the first fixing member and the second fixing member are both connected to rollers, a moving plate is provided under the roller, a plurality of grooves are opened on the top of the base, guide rods are connected in the grooves, the bottom end of the second fixing member is connected to a connecting block, and the surface of the connecting block is connected to a second screw rod.

[0007] A further preferred solution is that there are three grooves and three connecting blocks in total, and the connecting blocks are located in the grooves, and the three grooves are equidistantly opened on the top surface of the base.

[0008] A further preferred solution: there are 2 guide rods in total, and the guide rods pass through the connecting blocks on the front and rear sides of the bottom end of the second fixing member. The guide rods are respectively located in the grooves on the front and rear sides of the top end of the base and are fixedly connected to the grooves. The second screw rod is threadedly connected to the connecting block in the middle of the bottom end of the second fixing member. The second screw rod is located in the groove opened in the middle of the top end of the base and is rotatably connected to the groove.

[0009] A further preferred solution is that there are two rollers in total, which are rotatably connected to the first fixing member and the second fixing member respectively.

[0010] A further preferred solution is that an inner cavity is provided in each of the first fixing member and the second fixing member, and the moving plate and the moving block are both located in the inner cavity.

[0011] A further preferred solution is that the top of the movable plate is in an arc shape, and the diameter of the arc is the same as the diameter of the roller, and the left and right sides of the bottom of the movable plate are both sloped.

[0012] A further preferred solution is that the top of the moving block is sloped and corresponds to the bottom of the moving plate, the top of the moving block contacts the bottom of the moving plate, and the first screw rod passes through the moving block and is threadedly connected to the moving block.

[0013] Beneficial effects:

[0014] 1. By providing a connecting block and a guide rod, the second screw rod is rotated, and the second screw rod drives the connecting block to move left and right, thereby driving the second fixing member to move left and right along the side wall of the guide rod. When the explosion-proof membrane is fixed to the first fixing member and the second fixing member, the tension of the surface of the explosion-proof membrane can be adjusted by moving the second fixing member to prevent the explosion-proof membrane from being too tight and affecting the test results;

[0015] 2. By setting a roller, one end of the explosion-proof membrane is placed on the bottom end of the roller of the first fixing member, and the explosion-proof membrane is in contact with the surface of the roller. Then the staff rotates the roller to move the explosion-proof membrane along the surface of the roller, so that the explosion-proof membrane passes through the first fixing member, thereby preventing the explosion-proof membrane from wrinkling when moving;

[0016] 3. By providing a movable plate and a movable block, when the explosion-proof membrane passes through the first fixing member and the roller at its top, the first screw is rotated to make the movable block move toward the middle of the base along the first screw. When the movable block moves, the top bevel of the movable block will abut against the bottom end of the movable plate, thereby causing the movable plate to gradually move upward, so that the top end of the movable plate drives the explosion-proof membrane to be in close contact with the surface of the roller until the roller is fixed. The explosion-proof membrane can be fixed by clamping the roller and the movable plate. BRIEF DESCRIPTION OF THE DRAWINGS
