[0005] To solve the above problems, the technical solution of the utility model is as follows:

[0006] A glass fiber reinforced plastic diaphragm frame includes an electrolytic cell, a fixed frame is connected to the upper end of the electrolytic cell, and further includes a diaphragm plate and a connecting piece. A plurality of diaphragm plates are arranged at intervals in the electrolytic cell. The front and rear ends of the diaphragm plate are respectively connected to the front and rear parts of the fixed frame through the connecting piece. The connecting piece at the rear side includes a clamping groove, a receiving groove, a clamping block and a pull rod. A clamping groove with an opening facing the inner surface at the rear side of the fixed frame is arranged at the upper rear end of the diaphragm plate. A receiving groove opposite to the opening of the clamping groove is arranged on the inner surface at the rear side of the fixed frame. The clamping block is a right-angled triangular prism with a top surface being an inclined surface with the rear end higher than the front end. The rear part of the clamping block slides into the receiving groove, and the front part slides into the clamping groove. A spring is connected between the rear end of the clamping block and the rear side surface of the receiving groove. A pull rod connected to the rear end of the clamping block and with a free end movably penetrating through the rear side of the fixed frame of the receiving groove is arranged. A limiting member for limiting the movement of the pull rod is arranged on the fixed frame.

[0007] Furthermore, the bottom surface and the left and right side surfaces of the rear part of the clamping block of the connecting piece at the rear side are in sliding contact with the side surfaces of the corresponding receiving groove, and the bottom surface and the left and right side surfaces of the front part of the clamping block are in sliding contact with the side surfaces of the corresponding clamping groove.

[0008] Further, when the rear part of the clamping block of the rear-side connecting member is located in the corresponding receiving groove and the front part is located in the corresponding clamping groove, the upper part of the top surface of the clamping block contacts the rear end of the top surface of the clamping groove, and the spring is in a natural state.

[0009] Further, a pull plate is connected to the free end of the pull rod of the rear-side connecting member, and the spring is sleeved outside the pull rod. When the spring is in a natural state, the pull plate contacts the outer rear side of the fixing frame.

A limiting screw rod corresponding to the pull plate is fixed on the outer rear side of the fixing frame, and the free end of the limiting screw rod penetrates through the corresponding pull plate and is limited by the limiting nut.

[0011] Further, positioning rods are fixed on the inner side surfaces of the left and right sides of each receiving groove in the fixing frame, and both of the two positioning rods contact the left and right side surfaces of the diaphragm plate corresponding to the receiving groove.

[0012] By the above technical solutions, the beneficial effects of the present utility model are as follows:

[0013] When the diaphragm plate of the present utility model moves downward, the clamping blocks on the front and rear sides of the diaphragm plate can extend into the clamping grooves of the diaphragm plate under the action of the spring, and the movement of the clamping blocks is limited by the limiting member, so that the connection between the diaphragm plate and the fixing frame can be completed quickly and conveniently, and the diaphragm plate will not be affected and deformed.

[0014] After the limiting member releases the limitation on the pull plate in the present utility model, the clamping block is pulled by the pull plate. After the clamping blocks in the front and rear clamping grooves of the diaphragm plate are disengaged from the clamping grooves, the diaphragm plate is lifted upward, that is, the diaphragm plate is disassembled, and the connection between the diaphragm plate and the fixing frame is released; the disassembly is convenient.

Detailed Embodiment

[0020] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0021] As Figures 1 to 4 shown, a fiberglass diaphragm frame includes an electrolytic cell 1, and a fixing frame 2 is connected to the upper end of the electrolytic cell 1. The fixing frame 2 is a rectangular frame. It is characterized in that it further includes a diaphragm plate 3 and a connecting member. A plurality of diaphragm plates 3 are arranged at intervals in the electrolytic cell 1. The diaphragm plates 3 are used to carry diaphragms. A partition rod 4 is arranged between every two diaphragm plates 3. The front and rear ends of the partition rod 4 are respectively connected to the front and rear inner surfaces of the fixing frame 2. The front and rear ends of the diaphragm plate 3 are respectively connected to the front and rear parts of the fixing frame 2 through the connecting member. The connecting members on the front and rear sides of the same diaphragm plate 3 are symmetric in the front and rear. The connecting member at the rear side includes a clamping groove 5, a receiving groove 6, a clamping block 7 and a pull rod 8. A clamping groove 5 with an opening facing the inner surface at the rear side of the fixing frame 2 is arranged at the upper rear end of the diaphragm plate 3. The clamping groove 5 is a rectangular groove body. A receiving groove 6 opposite to the opening of the clamping groove 5 is arranged on the inner surface at the rear side of the fixing frame 2. The receiving groove 6 is a rectangular groove body. The clamping block 7 is a right-angled triangular prism with a rear-high and front-low inclined surface on the top surface. The rear part of the clamping block 7 slides into the receiving groove 6 and the front part slides into the clamping groove 5. A spring 9 is connected between the rear end of the clamping block 7 and the rear side surface of the receiving groove 6. A pull rod 8 connected to the rear end of the clamping block 7 and with a free end movably passing through the fixing frame 2 at the rear side of the receiving groove 6 is provided. The pull rod 8 is a round rod body, and a limiting member for limiting the movement of the pull rod 8 is arranged on the fixing frame 2.

[0022] The bottom surface and the left and right side surfaces of the rear part of the clamping block 7 of the connecting member at the rear side are in sliding contact with the side surfaces of the corresponding receiving groove 6, and the bottom surface and the left and right side surfaces of the front part of the clamping block 7 are in sliding contact with the side surfaces of the corresponding clamping groove 5.

[0023] When the rear part of the clamping block 7 of the connecting member at the rear side is located in the corresponding receiving groove 6 and the front part is located in the corresponding clamping groove 5, the upper part of the top surface of the clamping block contacts the rear end of the top surface of the clamping groove, and the spring 9 is in a natural state.

[0024] A pull plate 10 is connected to the free end of the pull rod 8 of the connecting member at the rear side. The pull plate 10 is a rectangular plate body. The spring 9 is sleeved on the pull rod 8. When the spring 9 is in a natural state, the pull plate 10 contacts the outer rear side surface of the fixing frame 2.

[0025] The limiting member includes a limiting screw 11 and a limiting nut 12. A limiting screw 11 corresponding to the pull plate 10 is fixed on the outer rear side surface of the fixing frame 2. The free end of the limiting screw 11 passes through the corresponding pull plate 10 and is limited by the limiting nut 12. A through hole 13 for the limiting screw 11 to pass through is arranged on the pull plate 10.

[0026] On the inner sides of the fixing frames 2 on the left and right sides of each accommodating groove 6, positioning rods 14 are fixedly installed, and both of the two positioning rods 14 are in contact with the left and right side surfaces of the diaphragm plate corresponding to the accommodating groove 6; the positioning rod 14 is a rectangular rod.

[0027] Before installation, the springs 9 on each connecting piece are in a natural state. Loosen the limit nuts 12 on each limit screw 11 to make the limit nuts 12 move away from the corresponding pull plates, so that the limit nuts do not affect the movement of the corresponding pull plates 10. At this time, the end of each clamping block 7 extends out of the corresponding accommodating groove 6.

[0028] During installation, make the diaphragm plate 3 move downward. When the diaphragm plate 3 moves downward, the rear end of the diaphragm plate 3 passes between the two positioning rods 14 on the corresponding rear side. During the downward movement of the diaphragm plate 3, the lower end of the rear side surface of the diaphragm plate 3 presses downward on the top surface of the clamping block 7 between the two positioning rods 14, driving the clamping block 7 at the rear of the fixing frame 2 to move backward, and the spring 9 is compressed until the slot 5 at the rear end of the diaphragm plate 3 and the opening of the accommodating groove 6 where the clamping block 7 is located are opposite. Under the restoring force of the spring 9, the clamping block 7 moves forward, and the front end of the clamping block 7 extends into the slot 5 at the rear end of the diaphragm plate 3. Similarly, the lower end of the front side surface of the diaphragm plate 3 presses downward on the top surface of the clamping block 7 between the two positioning rods 14 at the front of the fixing frame 2, driving the clamping block 7 at the front of the fixing frame 2 to move forward, and the spring 9 is compressed until the slot 5 at the front end of the diaphragm plate 3 and the opening of the accommodating groove 6 where the clamping block 7 is located are opposite. Under the restoring force of the spring 9, the clamping block 7 moves backward, and the rear end of the clamping block 7 extends into the slot 5 at the front end of the diaphragm plate 3; subsequently, tighten the limit nuts 12 on the fixing frames 2 on the front and rear sides of the diaphragm plate 3. The limit nuts 12 limit the movement of the corresponding pull plates 10, and the clamping blocks 7 in the slots 5 at the front and rear ends of the diaphragm plate 3 are limited, and the connection between the diaphragm plate 3 and the fixing frame 2 is completed.

[0029] When it is necessary to disassemble the diaphragm plate 3, loosen the limit nuts 12 on the fixing frames 2 on the front and rear sides of the diaphragm plate 3, and at the same time pull the connected clamping block 7 through the pull plate 10, so that the clamping blocks 7 in the slots 5 at the front and rear ends of the diaphragm plate move away from each other until each clamping block 7 disengages from the corresponding slot 5, and then lift the diaphragm plate 3 upward to disassemble the diaphragm plate 3 and release the connection between the diaphragm plate 3 and the fixing frame 2.

[0030] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Without departing from the spirit of the present invention, that is, within the scope of disclosure, any equivalent or equivalent deformation or replacement of the technical solutions of the present invention belongs to the protection scope of the present invention.
