[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0014] An oven for glazing ridge tiles includes an oven, conveyor rollers spaced apart inside the oven along the conveying direction of the ridge tiles, and rotating shafts connected to both ends of the conveyor rollers. When the conveyor rollers need to be installed, the operator pushes the limiting sleeve towards the limiting block to compress the second spring, exposing the through hole. The limiting sleeve then releases its restriction on the limiting bead. Subsequently, the connecting rod is inserted into the insertion groove of the connector and moved to its bottom to compress the first spring. The connecting rod is continued to be pushed towards the bottom of the insertion groove until the groove is below the limiting bead. Then, the limiting sleeve is released, and under the tension of the second spring, the limiting sleeve resets to cover the through hole. The limiting bead moves towards the groove, partially embedding itself in the groove to lock the connecting rod. Under the pressure of the limiting sleeve on the limiting bead, the steel ball continues to lock the connecting rod, completing the installation of the conveyor roller. When the conveyor roller needs to be disassembled, the operator pushes the limiting sleeve towards the limiting block to press the second spring, exposing the through hole. The limiting sleeve releases its pressure on the limiting bead, and the limiting bead disengages from the groove, releasing the locking of the connecting rod. Under the tension of the first spring, the first spring pushes the connecting rod away from the insertion groove, allowing the operator to pull out the conveyor roller. This setup enables quick installation and disassembly of the conveyor roller. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.
[0024] Example
[0025] Please see Figures 1-3 An oven 10 for glazing ridge tiles includes an oven 10, conveyor rollers 20 disposed inside the oven 10 and spaced apart along the conveying direction of the ridge tiles, and rotating shafts 30 connected to both ends of the conveyor rollers 20. The rotating shafts 30 are provided with connectors 31, each connector 31 having an insertion groove 32. A first spring 321 is disposed at the bottom of the insertion groove 32. For example, a pressure plate 322 is slidably connected to the insertion groove 32 along its length. The pressure plate 322 is connected to the first spring 321. When the conveyor rollers 20 need to be installed, the connecting rod 21 presses the pressure plate 322 to compress the first spring. Spring 321 and pressure plate 322 can evenly transmit the force of connecting rod 21 to first spring 321, reducing local stress concentration and reducing deformation or damage of first spring 321. During disassembly, the pressure plate 322 is pushed by the tension of first spring 321 to make connecting rod 21 move away from insertion groove 32. Pressure plate 322 can provide a stable contact surface, so that the tension of spring is transmitted to connecting rod 21 more evenly. Pressure plate 322 slides along the inner wall of insertion groove 32, improving the stability of movement of connecting rod 21 and first spring 321.
[0026] The insertion slot 32 has through holes spaced apart along its circumference, and a limiting bead 323 is embedded in the through hole. For example, the limiting bead 323 is a steel ball, which has higher strength, is more durable, and is not easy to wear. The outer surface of the connector 31 is fitted with a limiting sleeve 324 that compresses the limiting bead 323 to move inward. A limiting block 325 is provided on the outer surface of the connector 31 and on the side of the limiting sleeve 324 near the rotating shaft 30. A second spring 326 is connected between the limiting sleeve 324 and the limiting block 325. For example, a sleeve 33 is fitted on the outer surface of the limiting block 325. The sleeve 33 covers the second spring 326 and the limiting block 325, making the overall appearance of the connector 31 simpler and more beautiful. One end of the sleeve 33 is fixedly connected to the limiting sleeve 324, and the other end of the sleeve 33 is slidably connected to the limiting block 325, which enhances the stability of the limiting sleeve 324 when it moves.
[0027] Both ends of the conveying roller 20 are provided with connecting rods 21 that are inserted into the insertion slots 32. The connecting rods 21 are provided with grooves 211 corresponding to the limiting beads 323 along their circumference. For example, the two sides of the grooves 211 are inclined surfaces that slope towards their bottom, which makes it easy for the limiting beads 323 to slide into and out of the grooves 211.
[0028] An oven 10 for glazing ridge tiles includes an oven 10, conveying rollers 20 disposed within the oven 10 and spaced apart along the conveying direction of the ridge tiles, and rotating shafts 30 connected to both ends of the conveying rollers 20. When the conveying rollers 20 need to be installed, the operator pushes the limiting sleeve 324 toward the limiting block 325 to compress the second spring 326, exposing the through hole. The limiting sleeve 324 then releases its restriction on the limiting bead 323. Subsequently, the connecting rod 21 is inserted into the insertion groove 32 of the connector 31 and moved to its bottom to compress the first spring 321. The connecting rod 21 is continued to be pushed toward the bottom of the insertion groove 32 until the groove 211 is below the limiting bead 323. Then, the limiting sleeve 324 is released, and under the tension of the second spring 326, the limiting sleeve 324 resets and covers the through hole. The limiting sleeve 324 compresses the limiting bead 323. The positioning bead 323 moves toward the groove 211, and the limiting bead 323 partially embeds into the groove 211 to lock the connecting rod 21. Under the pressure of the limiting sleeve 324 on the limiting bead 323, the steel ball continues to lock the connecting rod 21, completing the installation of the conveyor roller 20. When it is necessary to disassemble the conveyor roller 20, the operator pushes the limiting sleeve 324 toward the limiting block 325 to press the second spring 326, exposing the through hole. The limiting sleeve 324 releases the pressure on the limiting bead 323, and the limiting bead 323 disengages from the groove 211, releasing the locking of the connecting rod 21. Under the tension of the first spring 321, the first spring 321 pushes the connecting rod 21 toward the direction away from the insertion groove 32, and the operator can then pull out the conveyor roller 20. This setting enables the quick installation and disassembly of the conveyor roller 20.
[0029] In another embodiment, the inner wall of the insertion groove 32 is provided with a limiting ring 327 along its circumference to limit the insertion depth of the connecting rod 21. The connecting rod 21 is provided with a limiting part 212 corresponding to the limiting ring 327. When the connecting rod 21 is inserted into the insertion groove 32, when the limiting part 212 of the connecting rod 21 abuts against the limiting ring 327 in the limiting groove, the groove 211 is just below the limiting bead 323. This prevents the operator from inserting the connecting rod 21 into the insertion groove 32 too deeply, causing the limiting bead 323 to misalign with the groove 211, making it impossible to lock the connecting rod 21, and resulting in the connecting rod 21 and the insertion groove 32 not being able to connect effectively.
[0030] In another embodiment, a baffle 331 is provided at the end of the sleeve 33 away from the limiting sleeve 324. The baffle 331 is used to limit the movement distance of the limiting sleeve 324. The limiting sleeve 324 is reset under the tension of the second spring 326. When the baffle 331 abuts against the side of the limiting block 325 away from the limiting sleeve 324, the limiting sleeve 324 covers the through hole and squeezes the limiting bead 323.
[0031] In another embodiment, the front opening of the insertion slot 32 is chamfered. The chamfer can serve as a guide to help the connecting rod 21 be smoothly inserted into the insertion slot 32, reducing resistance during assembly and thus improving assembly efficiency.
[0032] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
