Detailed Embodiment

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. In addition, for the convenience of description below, the "upper", "lower", "left", "right", etc. cited are consistent with the upper, lower, left, right, etc. of the accompanying drawings themselves. The "first", "second", etc. in the following text are for distinction in description and have no other special meanings.

[0031] Aiming at the problems existing in the prior art, the present utility model provides a novel structure of a sealing belt for a track. The novel structure of the sealing belt includes a track base body and a sealing belt body arranged on the upper side of the track base body, which is specifically described as follows:

[0032] 1 - Track base body

[0033] A preset groove is opened at the lower end of the above-mentioned track base body, and a support plate is arranged inside the track base body. A positioning rod is arranged inside the support plate, and a guiding block is arranged outside the support plate. A return spring is arranged at the lower end of the guiding block. The support plate cooperates with the positioning rod to position and guide the sealing belt body, so that the sealing belt body is not prone to position deviation during the installation process, improving the installation efficiency of the device; the guiding block cooperates with the return spring to push the positioning rod and the support plate to move up and down and reset inside the track base body, so that the support plate cooperates with the positioning rod to push the deformed sealing belt body to restore and reset, improving the use effect and service life of the device.

[0034] In some examples, the above-mentioned sealing belt body is relatively engaged with both the support plate and the positioning rod, and the positioning rods are arranged at equal intervals inside the support plate. By installing the sealing belt body along the positioning rod on the upper side of the support plate, the positioning rod guides the installation position of the sealing belt body, avoiding the position deviation of the sealing belt body during the installation process and improving the installation efficiency of the device.

[0035] In some examples, the above-mentioned guiding block is relatively slidably arranged with the track base body, and the cross-section of the guiding block is a "T"-shaped structure. By guiding the displacement of the positioning rod and the support plate through the guiding block, when the device is squeezed during use, due to the elastic material characteristics of the sealing belt body at this time, the sealing belt body pushes the support plate and the positioning rod to displace downward along the guiding block. At this time, the return spring rebounds and buffers to push the positioning rod and the support plate to reset and rebound. The sealing belt body is supported by the support plate and the positioning rod to reset, avoiding the sealing belt body being difficult to recover after deformation and improving the service life of the device.

[0036] 2 - Sealing belt body

[0037] A preset cavity is formed inside the above-mentioned sealing tape body, and a stress groove is provided at the lower end of the sealing tape body. A first wing portion is provided on the outer side of the lower end of the sealing tape body, a second wing portion is provided on the upper side of the first wing portion, a third wing portion is provided on the upper side of the second wing portion, and anti-slip soft teeth are provided on the upper side of the third wing portion. A connecting block is provided on the outer side of the third wing portion, a drainage groove is provided on the inner side of the third wing portion, and a limiting component is provided on the outer side of the connecting block. By means of the connecting rod cooperating with the guiding rod to drive the limiting block to displace outward on the upper side of the track base body, the limiting of the connecting block by the limiting block is released, facilitating the operator to take out the sealing tape body and the connecting block upward, improving the disassembly, assembly and maintenance efficiency of the device, and reducing the disassembly, assembly and maintenance cost of the device.

[0038] In some examples, the above-mentioned limiting component includes a limiting block installed on the outer side of the connecting block, a guiding rod is provided on the outer side of the limiting block, a connecting rod is provided inside the limiting block, and a limiting rod is provided on the upper side of the connecting rod. When the device is damaged, by taking out the limiting rod outward, the limiting of the connecting rod by the limiting rod is released. At this time, the connecting rod drives the limiting block to displace outward along the guiding rod, so that the limiting of the connecting block by the limiting block is released, facilitating the operator to take out the sealing tape body and the connecting block upward, improving the disassembly, assembly and maintenance efficiency of the device, and reducing the disassembly, assembly and maintenance cost of the device.

[0039] In some examples, the above-mentioned limiting block and the connecting block are relatively engaged, the limiting block and the guiding rod are relatively slidable, and the longitudinal section of the guiding rod is a "T"-shaped structure. When the device is damaged, by taking out the limiting rod outward, the limiting of the connecting rod by the limiting rod is released. At this time, the connecting rod drives the limiting block to displace outward along the guiding rod, so that the limiting of the connecting block by the limiting block is released, facilitating the operator to take out the sealing tape body and the connecting block upward, improving the disassembly, assembly and maintenance efficiency of the device, and reducing the disassembly, assembly and maintenance cost of the device.

[0040] In some examples, the above-mentioned connecting rod and the limiting block are relatively threaded, and the limiting rod is relatively engaged with both the connecting rod and the track base body. When the device is damaged, by taking out the limiting rod outward, the limiting of the connecting rod by the limiting rod is released. At this time, the connecting rod drives the limiting block to displace outward along the guiding rod, so that the limiting of the connecting block by the limiting block is released, facilitating the operator to take out the sealing tape body and the connecting block upward, improving the disassembly, assembly and maintenance efficiency of the device, and reducing the disassembly, assembly and maintenance cost of the device.

[0041] In some examples, the above-mentioned anti-slip soft teeth are arranged at equal intervals on the upper side of the third wing part, and the longitudinal section of the anti-slip soft teeth is a triangular structure. By arranging the anti-slip soft teeth on the upper side of the third wing part, the contact area between other objects and the sealing strip body is increased through the anti-slip soft teeth, so that the connection and contact between other objects and the sealing strip body are more stable, and the anti-slip contact ability of the device is improved.

[0042] In some examples, the above-mentioned connecting block is arranged in relative engagement with the track base body, and the connecting block is arranged symmetrically about the central axis of the sealing strip body. The sealing strip body is fixed inside the track base body through the cooperation of the connecting block and the track base body, so that the sealing strip body seals the gap of the track base body, and the stability and durability of the track base body are improved.
