DETAILED DESCRIPTION

[0027] The utility model is further described below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 5 As shown, a feeding rack limiting device dedicated to a spandex spinning corridor comprises a base 1 and a feeding rack arranged on the base 1 and capable of laterally moving relative to the base 1, a fixed block 3 is fixedly connected to a side support column 2a of the feeding rack, a rotating rod 4 which can rotate relative to the fixed block 3 is arranged on the fixed block 3, a first limiting structure 5 for limiting the feeding rack is arranged on the rotating rod 4, a first positioning component 6 is arranged on one end of the rotating rod 4 away from the fixed block 3, a second positioning component 7 matched with the positioning component and a second limiting structure 8 matched with the first limiting structure 5 are arranged on the base 1.

[0029] In this embodiment, a rotating rod 4 is provided on the fixed block 3 of the feeding rack, and a first limiting structure 5 for limiting the feeding rack is provided on the rotating rod 4. A first positioning component 6 is provided on the end of the rotating rod 4 away from the fixed block 3. When the feeding rack moves to the end of the base 1 and needs to be fixed, the first positioning component 6 cooperates with the second positioning component 7, and then the rotating rod 4 rotates to achieve the cooperation between the first limiting structure 5 and the second limiting structure 8, which is convenient for operation.

[0030] In this embodiment, the fixing block 3 includes two mutually detachable assembly blocks 9, which can be connected by bolts, and each assembly block 9 is provided with an arc groove 10, and the arc grooves 10 on the two assembly blocks 9 cooperate to form an assembly opening 11 for the side support column to pass through.

[0031] In order to improve the adjustability of the assembly block 9, each assembly block 9 is provided with a block groove 12 for accommodating the block, and the block groove 12 extends from the surface of the arc groove 10 to the inside of the assembly block 9. The block is equivalent to an assembly block 9 of different sizes that can be embedded in the block groove 12, so as to adapt to feeding racks of different sizes and improve adaptability. Those skilled in the art should understand that the block described in this embodiment is a prior art.

[0032] In this embodiment, the first limiting structure 5 includes a shift lever 13 arranged on the rotating rod 4, the shift lever 13 extends radially outward from the outer surface of the rotating rod 4, and when the rotating rod 4 rotates, the shift lever 13 is linked with the rotating rod 4 to be snapped into the second limiting structure 8. In further detail, the second limiting structure 8 includes a shift lever groove 14 opened on the base 1, and the cross-section of the shift lever groove 14 is an arc shape.

[0033] When the rotating rod 4 rotates, the shift lever 13 is linked with the rotating rod 4. After the shift lever 13 penetrates into the shift lever groove 14, the horizontal movement stroke of the feeding rack is limited.

[0034] In this embodiment, the first positioning component 6 includes a positioning shaft 15 arranged on the rotating rod 4 and a limiting sleeve 16 cooperating with the positioning shaft 15. The end of the limiting sleeve 16 away from the rotating rod 4 is provided with a through hole 17 through which the end of the positioning shaft 15 passes. Preferably, a positioning cavity 18 is arranged in the limiting sleeve 16, and a radially protruding positioning platform 19 is provided on the positioning shaft 15 and can slide laterally in the positioning cavity 18. In order to enable the positioning shaft 15 to rebound better and avoid excessive deviation of the positioning shaft 15, an elastic member 21 cooperating with the positioning platform 19 is arranged in the positioning cavity 18.

[0035] In order to improve the connection stability of the elastic member 21, the elastic member 21 is sleeved on the positioning shaft 15, and one end of the elastic member 21 abuts on the positioning platform 19, and the other end of the elastic member 21 abuts on the inner wall of the positioning cavity 18 away from the rotating rod 4. In this embodiment, the elastic member 21 is a spring.

[0036] The second positioning assembly 7 includes a positioning plate disposed on the base 1 , and a positioning hole 22 is formed on the positioning plate for the positioning shaft 15 to penetrate.

[0037] When the first positioning assembly 6 and the second positioning assembly 7 work together, the limiting sleeve 16 first contacts the positioning plate to stop the lateral movement of the limiting sleeve 16, and then the positioning shaft rod 15 uses the travel space of the positioning cavity 18, and its end will pass through the through hole 17 and through the positioning hole 22, thereby limiting the movement of the feeding rack in the up and down directions.

[0038] The base 1 is provided with a plurality of sliding wheels 23 for the lateral sliding of the feeding rack. The plurality of sliding wheels 23 are horizontally laid on the base 1 and can rotate relative to the base 1 to reduce the friction between the base 1 and the feeding rack, thereby improving the mobility.

[0039] The working principle of the utility model is as follows: a rotating rod 4 is arranged on the fixed block 3 of the feeding rack, and a first limiting structure 5 for limiting the feeding rack is arranged on the rotating rod 4. A first positioning assembly 6 is arranged on the end of the rotating rod 4 away from the fixed block 3. When the feeding rack moves to the end of the base 1 and needs to be fixed, the first positioning assembly 6 cooperates with the second positioning assembly 7. Specifically, during the cooperation, the limiting sleeve 16 first contacts the positioning plate to stop the lateral movement of the limiting sleeve 16, and then the positioning shaft rod 15 uses the stroke space of the positioning cavity 18, and its end will pass through the through hole 17 and through the positioning hole 22 to limit the movement of the feeding rack in the up and down directions. Then the rotating rod 4 rotates to realize the cooperation between the first limiting structure 5 and the second limiting structure 8. When the rotating rod 4 rotates, the gear lever 13 is linked with the rotating rod 4. After the gear lever 13 penetrates into the gear lever groove 14, the lateral movement stroke of the feeding rack is limited.
