[0010] As a further solution of the utility model: L-shaped side panels are symmetrically fixedly installed on both sides of the top of the light-transmitting plate, and a concave card plate is fixedly installed on the top of the L-shaped side panel, and the concave card plate is located at the top of both sides of the resin tank box.

[0011] As a further solution of the utility model: a fixed base frame is fixedly installed on the bottom of the light-transmitting plate, and fixed card slots are symmetrically arranged on both sides of the fixed base frame, and the fixed card slots correspond to the fixed card plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The resin tank of the 3D printer is provided with a fixed base, a sliding card plate, a fixed card plate and a fixed spring, and two sets of sliding card plates are pushed upward to make the sliding card plates away from the connecting plate, and the light-transmitting plate is placed on the top of the resin tank box accordingly. The fixed base passes through the bottom of the resin tank box and contacts the two sets of fixed card plates, and the fixed base is pressed downward. Under the rebound action of the fixed spring, the fixed card plate is inserted into the corresponding fixed card slot, and then the sliding card plate is controlled to slide down and be stuck on one side of the connecting plate, ensuring that the fixed card plate is stuck in the fixed card slot and will not be detached at will, and at the same time, it is convenient to disassemble or install the light-transmitting plate.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a 3D printer resin tank, including a resin tank box 1, wherein base feet 101 are fixedly installed at the four corners of the bottom of the resin tank box 1, a step groove 102 is provided at the central position of the bottom of the resin tank box 1, and two groups of elastic sealing rings 103 are fixedly installed at the bottom of the step groove 102. Due to the provision of the elastic sealing ring 103, when the light-transmitting plate 2 is fixed inside the step groove 102, the elastic sealing ring 103 is squeezed, deformed and rebounded between the light-transmitting plate 2 and the step groove 102, ensuring that the resin will not leak from the gap between the light-transmitting plate 2 and the step groove 102.

[0022] Rectangular grooves 104 are symmetrically provided on both sides of the bottom of the resin tank box 1, and sliding grooves 105 are symmetrically provided on both sides of the inner wall of the rectangular groove 104, and the sliding grooves 105 correspond to the sliding protrusions 405. Due to the sliding grooves 105, the fixed card plate 403 slides inside the rectangular groove 104, driving the sliding protrusion 405 to slide inside the sliding groove 105, ensuring that the fixed card plate 403 will not fall inside the rectangular groove 104 due to gravity.

[0023] A light-transmitting plate 2 is provided at the top of the resin tank box 1, and L-shaped side panels 201 are symmetrically fixedly installed on both sides of the top of the light-transmitting plate 2. A concave card plate 202 is fixedly installed on the top of the L-shaped side panel 201, and the concave card plate 202 is located at the top of both sides of the resin tank box 1. Because the L-shaped side panel 201 and the concave card plate 202 are provided, when the light-transmitting plate 2 is fixed to the bottom of the resin tank box 1, the L-shaped side panel 201 is tightly attached to the inner wall of the resin tank box 1, and at the same time, the concave card plate 202 is stuck on the top of both sides of the resin tank box 1, which is convenient for the operator to hold the concave card plate 202 to pull the light-transmitting plate 2 out of the resin tank box 1.

[0024] A fixed base frame 203 is fixedly installed at the bottom of the light-transmitting plate 2, and fixed card slots 204 are symmetrically provided on both sides of the fixed base frame 203, and the fixed card slots 204 correspond to the fixed card plates 403. By providing the fixed card slots 204, after the fixed card plates 403 are correspondingly inserted into the fixed card slots 204, the fixed base frame 203 is clamped and fixed to the bottom of the resin tank box 1.

[0025] The two sides of the bottom of the resin tank box 1 are symmetrically fixed with mounting plates 4, and the two sides of the mounting plates 4 are symmetrically slidably installed with fixing rods 401, and one end of the two groups of fixing rods 401 passes through the mounting plates 4 and is fixedly installed with connecting plates 402, and the ends of the two groups of fixing rods 401 away from the connecting plates 402 are fixedly installed with fixing clamping plates 403; the surfaces of the fixing rods 401 located between the mounting plates 4 and the fixing clamping plates 403 are provided with fixing springs 404, and the tops of the two sides of the fixing clamping plates 403 are symmetrically fixed with sliding protrusions 405, and by providing fixing springs 404, when the fixed base frame 203 contacts the fixed clamping plates 403 to lift the fixed clamping plates 403, under the elastic action of the fixing springs 404, the fixed clamping plates 403 can be tightly attached to the fixed base frame 203, ensuring that after the fixed clamping slots 204 correspond to the fixed clamping plates 403, the fixed clamping plates 403 can be clamped into the corresponding fixed clamping slots 204.

[0026] Fixed protrusions 3 are symmetrically fixedly installed on both sides corresponding to the resin tank box 1 and the mounting plate 4, and sliding clamps 301 are slidably installed on the surfaces of the two groups of fixed protrusions 3, and the sliding clamps 301 correspond to the connecting plate 402. Because the sliding clamps 301 are provided, when the sliding clamps 301 slide down and are clamped on one side of the connecting plate 402, the connecting plate 402 is clamped and fixed to ensure that the fixed clamps 403 will not arbitrarily separate from the fixed slot 204.

[0027] A rubber pad 302 is fixedly installed on one side of the sliding card plate 301 close to the resin tank box 1, and the rubber pad 302 corresponds to the connecting plate 402. Because of the rubber pad 302, when the sliding card plate 301 slides to the side of the connecting plate 402, the rubber pad 302 is squeezed and deformed between the sliding card plate 301 and the connecting plate 402, ensuring that the sliding card plate 301 will not slide off at will when it is pressed against one side of the connecting plate 402.

[0028] The working principle of the utility model is:

[0029] Push the sliding card plate 301 upwards, and fix the sliding card plate 301 on both sides of the resin tank box 1 under the squeeze and rebound effect of the rubber card pad 302, put the light-transmitting plate 2 into the stepped groove 102 accordingly, so that the fixed base frame 203 passes through the bottom of the resin tank box 1 and is stuck between the two sets of fixed card plates 403 until the fixed card plate 403 is stuck in the corresponding fixed card slot 204, and at the same time, the concave card plate 202 is stuck at the top of both sides of the resin tank box 1, and push the sliding card plate 301 downwards until the rubber card pad 302 is pressed against the top of both sides of the resin tank box 1. The clamping pad 302 is pressed against one side of the connecting plate 402 to clamp and fix the connecting plate 402, so that the fixed clamping plate 403 is clamped in the corresponding fixed clamping groove 204 to clamp and fix the fixed base frame 203. When the light-transmitting plate 2 is pulled out from the resin tank box 1, the sliding clamping plate 301 is pushed upward away from the connecting plate 402, and the fixed clamping plate 403 is pushed to both sides. At the same time, the two sets of concave clamping plates 202 are pulled up, driving the L-shaped side plate 201 and the light-transmitting plate 2 to move up and away from the bottom of the resin tank box 1.
