[0029] Example 1:

[0030] like Figures 1 to 6 As shown, this embodiment provides a heald belt adjustment seat of a circular loom, comprising a base 1 and a movable plate 2, wherein the base 1 is provided with a first hinge portion 100, and the movable plate 2 is provided with a second hinge portion 200, the base 1 and the movable plate 2 are hinged through the first hinge portion 100 and the second hinge portion 200, and the movable plate 2 is provided with at least one pair of adjusting screws 3 for adjusting the side height of the movable plate 2, each adjusting screw 3 includes an abutting portion for abutting against the circular loom and an adjusting portion for adjusting its own rotation, and also includes a cover plate 4, the cover plate 4 and the base 1 or the movable plate 2 are movably connected by a connecting structure, and the connecting structure is a hinged connection or a sliding connection or a flexible connection, and the cover plate 4 has a first state of covering the adjusting screw 3 and a second state of exposing the adjusting screw when it is active, so that through the design of the movable cover plate 4, when the adjusting screw 3 does not need to be operated, the cover plate 4 can be in the first state, effectively blocking the entry of dust and debris, which can significantly reduce the pollution of the adjusting screw 3 and extend its service life. Secondly, the area around the adjusting screw 3 can be cleaned through simple movable operations, making the maintenance process simpler and more efficient.

[0031] The sliding connection only requires that the cover plate 4 be slidably arranged relative to the base 1 or the movable plate 2 , such as a protrusion and a sliding groove matching structure.

[0032] The flexible connection is a soft connection or a rope connection. The soft connection is that the cover plate 4 and the base 1 or the movable plate 2 are integrally injection-molded during the injection molding, and the two are connected by a thin and flexible soft belt.

[0033] In this embodiment, there are two adjusting screws 3 , and nuts 300 are provided on the adjusting screws 3 . The nuts 300 are located above the upper end surface of the movable plate 2 .

[0034] In the embodiment of the present disclosure, a hinged connection is preferably adopted. Specifically, a third hinge part 400 is provided on the cover plate 4, and the cover plate 4 and the base 1 are hinged through the first hinge part 100 and the third hinge part 400. With such a configuration, the cover plate 4 can switch between the first state and the second state when it rotates, and the cover plate 4 can be opened and closed by simply flipping it.

[0035] Secondly, the first hinge part 100 is a shaft 5 provided on the base 1, the second hinge part 200 is a first hook 6 provided on the movable plate 2, and the third hinge part 400 is a second hook 7 provided on the cover plate 4. The hook is rotatably hooked on the shaft 5, and an opening is provided on the hook for the shaft 5 to enter and exit the hook. The first hook 6 and the second hook 7 are staggered along the axial direction of the shaft 5. It can be understood that the position where the first hook 6 forms a hinge with the second hook 7 and the shaft 5 needs to be staggered along the axial direction of the shaft 5.

[0036] Optionally, the second hinge part 200 is a first hook 6 arranged in the middle of the side of the movable plate 2 close to the base 1, and the third hinge part 400 is two second hooks 7 arranged on the side of the cover plate 4 close to the base 1, and the distance between the two second hooks 7 is not less than the length of the first hook 6. In this way, when the first hook 6 and the second hook 7 are hinged on the shaft 5, the two second hooks 7 are located on both sides of the first hook 6, so as to facilitate the uniform arrangement of the hooks on the movable plate 2 and the cover plate 4, thereby improving the stability of the two when rotating.

[0037] Preferably, the length of the first hook 6 is greater than the length of the second hook 7 and is not less than half the length of the movable plate 2. Since the movable plate 2 is provided with an adjusting screw 3, and the cover plate 4 is only used to cover the adjusting screw 3, the strength and stability requirements of the movable plate 2 will be higher than those of the cover plate 4. Therefore, by increasing the length of the first hook 6, the hinged connection between the movable plate 2 and the shaft 5 is more reliable, and at the same time has better stability during rotation.

[0038] Furthermore, positioning partitions 8 are provided between adjacent hooks on the base 1 , so that independent mounting openings are separated on the shaft 5 corresponding to each hook, thereby preventing the movable plate 2 and the cover plate 4 from axially moving on the shaft 5 .

[0039] Preferably, the positioning partition 8 and the shaft body 5 are connected to the base 1 as a whole, which improves the strength of the shaft body 5 and thus improves the reliability of the hinged connection.

[0040] It can be understood that the hook does not refer to a single hook, but may also refer to a plurality of sub-hooks arranged at intervals. For example, the second hook 7 is composed of a plurality of sub-hooks arranged in parallel at intervals.

[0041] In some embodiments, a cavity 9 corresponding to each other is provided on the cover plate 4 toward the adjusting screw 3. The cavity 9 is formed by a depression of the cover plate 4, and can also be hollowed out. When the cover plate 4 is in the first state, the adjusting screw 3 is in the corresponding cavity 9. The adjusting screw 3 is protected one by one by the independent cavity 9, thereby further extending the service life of the adjusting screw 3.

[0042] In some embodiments, a detachable connection structure is provided between the cover plate 4 and the movable plate 2, and the detachable connection structure is a snap connection, a magnetic connection, or a bolt connection. As for how these three detachable connection structures cooperate with the three movable connection structures so that the cover plate 4 can only be movable when force is applied and is relatively fixed when no force is applied, it should be reasonably set by those skilled in the art.

[0043] In this embodiment, a snap connection is preferably adopted. Specifically, at least one latch 10 is provided on the cover plate 4, and a notch 11 is provided on the movable plate 2 corresponding to the latch 10. For example, two latches 10 are symmetrically provided on the front side of the cover plate 4, or a latch 10 is provided in the middle of the front side of the cover plate 4. It should be understood that the number and position of the latches 10 can be reasonably adjusted by those skilled in the art, and the notch 11 is provided accordingly. For the specific structure of the latch 10 and the notch 11, reference can be made to the plastic snap structure in the prior art.

[0044] In some embodiments, a ridge 12 extends from the front side of the cover plate 4, generally disposed at the upper end of the front side of the cover plate 4, and serves as a fulcrum for opening and closing the cover plate 4. Furthermore, the ridge 12 may also correspond to the latch 10. Since the latch 10 generally leaves a slot on the front end of the cover plate 4, dust and other debris can be prevented from entering the cavity 9 through the slot.

[0045] In some embodiments, a first indicator symbol 13 for indicating the opening direction of the cover 4 is provided on the outer wall of the tongue 10, and a second indicator symbol 14 for indicating the opening position of the cover 4 is provided on the movable plate 2, preferably an arrow symbol, which simplifies the operation of the device so that new users can quickly get started.

[0046] In some embodiments, the upper end surface of the cover plate 4 is an arc-shaped surface with a raised middle portion, which reduces dust accumulation on the cover plate 4 .

[0047] It should be understood that the cover plate 4 may also be provided with an operating port for operating the adjusting screw 3 , so that the cover plate 4 mainly serves to prevent the adjusting screw 3 from directly contacting the human body.

[0048] Regarding other structures of the adjustment seat, reference can be made to the patent publication number CN217869328U, which discloses a heald belt adjustment seat applied to a circular loom. Specifically, a roller assembly 15 is provided on the front side of the movable plate 2. Figure 6As shown, the roller assembly 15 includes a roller shaft 151, two bearings 152 and a sleeve 153 spaced apart from each other, and two opposing extension plates 17 are provided on the movable plate 2. The roller assembly 15 is disposed between the two extension plates 17, and the extension plates 17 cover the corresponding ends of the roller assembly 15. The opposing inner walls of the two extension plates 17 each have an inclined guide groove 18 into which the roller shaft 151 slides. The inclined guide groove 18 on the extension plates 17 is arranged to be inclined downward from the outside to the inside.

[0049] Secondly, it also includes a lock nut 16 which is sleeved on the adjusting screw 3 and located at the bottom of the movable plate 2. The lock nut 16 is threadedly matched with the adjusting screw 3 and is limited in circumferential rotation with the movable plate 2.
