DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort fall within the protection scope of the present application.

[0027] Embodiment one

[0028] Please refer to Figure 1 and Figure 2 The present application mainly aims at the circular inspection well body 1 for lining filling, and utilizes a plurality of lining plates 2 for free assembly, so as to realize that the lining plates 2 constitute a ring-shaped cylinder which can adapt to the inner side of the inspection well body 1.

[0029] The material of the lining plate 2 is mainly PVC sheet, and the lining plate 2 is combined with the drawings Figure 3 and Figure 4 As can be seen, the end of the lining plate 2 is provided with a lock tongue 3, the length of the lock tongue 3 is consistent with the axial length of the lining plate 2, and the other end of the lining plate 2 is provided with a lock groove part 4 for accommodating the lock tongue 3, Figure 4 The lock groove part 4 given in the drawings is a square groove structure, and this structure can ensure that the lock tongue 3 is clamped by the end of the lock groove part 4 when the lock tongue 3 is clamped into the lock groove part 4, so as to realize the connection and fixation between the two lining plates 2.

[0030] Combined with the drawings Figure 3 As can be seen, the outer side of the lining plate 2 is provided with a support protruding part 200, the cross-sectional shape is T-shaped, and the protruding height is consistent with the protruding height of the lining plate 2, so as to ensure that when the lining plate 2 is placed in the inspection well body 1, the outer side of the lining plate 2 is pasted on the inner side of the inspection well body 1 according to the support protruding part 200, and the phenomenon that the lining plate 2 and the inspection well body 1 are not enough in adhesion due to the local protruding support protruding part 200 is avoided.

[0031] As can be seen from the above, in the present application, the lining plate 2 is mainly assembled by assembly, so that the assembly is more flexible, so as to adapt to the protection work of the inspection well body 1 with different inner diameters, and at the same time, the lining plate 2 after assembly can prevent thermal expansion and contraction, and the PVC sheet is adopted, which can achieve the effects of anti-seepage and anti-corrosion, greatly increasing the service life of the inspection well body 1.

[0032] Embodiment two

[0033] As a deformation of embodiment one, please refer to Figure 5The end of the inner lining plate 2 is provided with a circular locking groove 400, and the lock tongue 3 is inserted into the tangent position of the circular locking groove 400. When the lock tongue 3 encounters the arc inside the circular locking groove 400, it will automatically change direction, and finally the lock tongue 3 is fixed in the circular locking groove 400 in the shape of "6".

[0034] During the subsequent outward pulling of the inner lining plate 2, the end of the lock tongue 3 is attached to the inside of the circular locking groove 400, which makes the lock tongue 3 have a certain resistance when pulled out, and increases the connection strength between the inner lining plates 2.

[0035] Example three

[0036] As another variation of example one, please refer to Figure 6 and Figure 7 Although the method of example two increases the resistance when the inner lining plate 2 is separated, and relatively increases the stability of the connection between the inner lining plates 2, in actual application, if the thickness of the lock tongue 3 is large enough to ensure a certain strength, the strength required during assembly between the inner lining plates 2 will increase, otherwise, if the lock tongue 3 is too thin, the connection strength will be relatively weakened.

[0037] This example three provides an elliptical locking groove 401 for the locking groove part 4, combined with Figure 7 It can be seen that the inside of the elliptical locking groove 401 has a anti-disengagement rod 5 fixedly connected by a connecting column 501. The anti-disengagement rod 5 is an elongated rod with an elliptical cross-sectional shape, and the connecting column 501 is relatively thin and has multiple, arranged equidistantly in the axial direction of the anti-disengagement rod 5, and the interval length is preferably between ten to twenty centimeters, so as to ensure that the anti-disengagement rod 5 can be stably placed in the elliptical locking groove 401.

[0038] Reference Figure 6 and Figure 7 It can be seen that the top of the anti-disengagement rod 5 is provided with a protruding locking part 500, and the cross-sectional shape is approximately a right-angled triangle. The end of the lock tongue 3 is provided with a sharp corner, and the lock tongue 3 is provided with an anti-disengagement part 300 on one side of the anti-disengagement rod 5.

[0039] During assembly between the inner lining plates 2, the end of the lock tongue 3 is guided through the inside of the elliptical locking groove 401 and the outside of the anti-disengagement rod 5, avoiding the phenomenon that the lock tongue 3 is not easy to bend into a "6" after being inserted. The end of the continuously inserted lock tongue 3 will be stopped on the connecting column 501, so that the connecting column 501 is broken, and finally the anti-disengagement part 300 will pass the locking part 500 to complete the connection and fixation.

[0040] Combined with Figure 2It can be seen that the inner lining plate 2 is axially long, so the length of the anti -off rod 5 is known, when the local inner lining plate 2 and the between are separated, the local lock tongue 3 will pull the anti-off rod 5 to move upward, because the lock tongue 3 drives the anti-off rod 5 to move upward, it will force the anti-off rod 5 to have the tendency of deflection along the arrow direction, the direction is referenced Figure 6 , so that 6 is clamped in the inside of the lock tongue 3, so that the resistance of the lock tongue 3 to the outside is increased.

[0041] Even if the local lock tongue 3 has the tendency of sliding outside the anti-off rod 5, the anti-off part 300 will hook the locking part 500, still force the anti-off rod 5 to have the tendency of rotation, and the above also said that the length of the anti-off rod 5 is long, when the local anti-off part 300 pulls the anti-off rod 5 to want to rotate, the other part of the anti-off rod 5 is still in contact with the lock tongue 3, that is, the fixed anti-off rod 5 and the lock tongue 3 always exist friction between them, the anti-off part 300 pulls the anti-off rod 5, not enough to make the anti-off rod 5 rotate, also ensures the stability of the structure.

[0042] Even if the whole axial lock tongue 3 has the tendency of moving outward, the anti-off part 300 can pull the locking part 500 to rotate, but after the anti-off rod 5 rotates, because the anti-off rod 5 is oval, combined with Figure 6 It can be seen that when the anti-off rod 5 rotates clockwise, the long axis will move to the short axis part, because the length of the short axis of the anti-off rod 5 and the thickness of the two lock tongues 3 is equal to the length of the short axis of the oval lock groove 401, so that the anti-off rod 5 will be directly stuck in the oval lock groove 401, so as to further limit the lock tongue 3 from being pulled outward.

[0043] As an example of three, in this embodiment, the outer side of the anti-off rod 5 is preferably provided with locking parts 500 at equal intervals, and the anti-off part 300 is provided with multiple, and the multiple anti-off parts 300 are arranged at equal intervals on one side of the anti-off rod 5, combined with Figure 6 It can be seen that when the anti-off rod 5 is provided with a whole circle of locking parts 500 on the outer side, the lock tongue 3 will inevitably cause the anti-off part 300 on the inside of the lock tongue 3 to be clamped on the locking part 500 when it is pulled upward, which ensures the connection strength between the lock tongue 3 and the anti-off part 300, and as mentioned above, the cross section of the locking part 500 is a right triangle, which will not affect the normal movement of the lock tongue 3 when it enters, and even if the connecting column 501 is in the state of not being broken, the lock tongue 3 cannot be pulled out, which ensures that the lock tongue 3 inserted into the oval lock groove 401 cannot be pulled out.
