[0033] The following further elaborates the present application in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. Additionally, it should be noted that for the sake of convenience of description, only the parts related to the utility model are shown in the drawings.

[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] At least see Figures 1 - 9 As shown, the utility model provides an embroidery frame assembly including: an embroidery frame 10, a first steel bar 31, a second steel bar 32 and a moving component 20.

[0036] The moving assembly 20 includes a first bearing 21 and a second bearing 22 .

[0037] The embroidery frame 10 includes a frame 11 and a guide rail 12 . The frame 11 has a receiving groove 101 . The guide rail 12 is disposed in the receiving groove 101 and divides the receiving groove 101 into a first slide groove 1011 and a second slide groove 1012 .

[0038] Among them, Figures 1 - 3 As shown, the receiving groove 101 of the frame 11 extends in the front-to-back direction. The length direction of the guide rail 12 is arranged in the front-to-back direction, and the guide rail 12 is arranged in the middle of the receiving groove 101 in the left-right direction to separate the receiving groove 101 into a first slide groove 1011 and a second slide groove 1012. The first slide groove 1011 and the second slide groove 1012 extend in the front-to-back direction.

[0039] It should be noted that if Figure 3 As shown, the first slide groove 1011 and the second slide groove 1012 share the guide rail 12 , the guide rail 12 in the first slide groove 1011 serves as the right groove wall of the first slide groove 1011 , and the guide rail 12 in the second slide groove 1012 serves as the left groove wall of the second slide groove 1012 .

[0040] The first bearing 21 is located in the first slide groove 1011, and the second bearing 22 is located in the second slide groove 1012. The first bearing 21 abuts against the guide rail 12, and the second bearing 22 abuts against the guide rail 12. In this way, when the embroidery frame moves in the front-back direction, the guide rail 12 of the frame 11 slides with the first bearing 21 and the second bearing 22, and in the current scene, the first bearing 21 and the second bearing 22 rotate; when the embroidery frame moves in the left-right direction, the guide rail 12 of the embroidery frame 10 abuts against the first bearing 21 and the second bearing 22, and in the current scene, the first bearing 21 and the second bearing 22 may not rotate.

[0041] In practical applications, the embroidery frame 10 is made of aluminum alloy. In order to prevent the first bearing 21 and the second bearing 22 from wearing the guide rail 12 of the embroidery frame 10, as shown in FIG. Figure 3 As shown, a first mounting groove 121 is formed by a depression on the surface of the side wall of the guide rail 12 facing the first bearing 21, and the first steel bar 31 is inserted and connected with the first mounting groove 121, so that the first bearing 21 abuts against the first steel bar 31, thereby preventing the first bearing 21 from wearing the guide rail 12 of the embroidery frame 10.

[0042] It should be noted that the notch of the first installation groove 121 is provided with a first upper stop portion 1211 and a first lower stop portion 1212. The first upper stop portion 1211 and the first lower stop portion 1212 stop or limit the first steel bar 31, so as to realize the stable insertion of the first steel bar 31 into the first installation groove 121.

[0043] Similarly, as Figure 3 shown, a second installation groove 122 is recessed on the surface of the guide rail 12 facing the side wall of the second bearing 22. The second steel bar 32 is inserted into the second installation groove 122, and the second steel bar 32 is inserted and connected with the second installation groove 122. In this way, the second bearing 22 abuts against the second steel bar 32, suppressing the wear of the guide rail 12 of the embroidery frame 10 by the second bearing 22.

[0044] It should be noted that the notch of the second installation groove 122 is provided with a second upper stop portion 1221 and a second lower stop portion 1222. The second upper stop portion 1221 and the second lower stop portion 1222 stop or limit the second steel bar 32, so as to realize the stable insertion of the second steel bar 32 into the second installation groove 122.

[0045] In practical applications, referring to Figure 2 and Figure 3 , the frame 11 has a vertical play, causing the first bearing 21 to collide with the above-mentioned first upper stop portion 1211 and first lower stop portion 1212. In this way, the first upper stop portion 1211 and the first lower stop portion 1212 are at risk of damage, and further cause the first steel bar 31 to disengage from the first installation groove 121. Similarly, the frame 11 has a vertical play, causing the second bearing 22 to collide with the above-mentioned second upper stop portion 1221 and second lower stop portion 1222. In this way, the second upper stop portion 1221 and the second lower stop portion 1222 are at risk of damage, and further cause the second steel bar 32 to disengage from the second installation groove 122.

[0046] Based on this, in the first specific embodiment, the cross-section of the first steel bar 31 is stepped.

[0047] For example, as Figure 4 and Figure 5 shown, the cross-section of the first steel bar 31 is a two-level step, including a first step 311 and a second step 312. The first step 311 is arranged in the first installation groove 121, and the first upper stop portion 1211 and the first lower stop portion 1212 stop or limit the first step 311, so as to realize the stable insertion of the first steel bar 31 into the first installation groove 121.

[0048] The second step 312 can protrude from the notch of the first installation groove 121, as Figure 5As shown, the left surface of the second step 312 protrudes from the notch of the first installation groove 121. Since both the first upper stop portion 1211 and the first lower stop portion 1212 are located at the notch of the first installation groove 121, and the left surface of the second step 312 abuts against the first bearing 21, there is a gap d1 in the left-right direction between the first upper stop portion 1211, the first lower stop portion 1212 and the left surface of the second step 312. When the frame 11 moves vertically, there is the above-mentioned gap d1 in the left-right direction between the first bearing 21 and the first upper stop portion 1211, the first lower stop portion 1212, thus avoiding the risk of collision between the first bearing 21 and the first upper stop portion 1211, the first lower stop portion 1212, and further contributing to the stable setting of the first steel bar 31 in the first installation groove 121.

[0049] Of course, it can be understood that the first steel bar 31 can be not only a two-level step, but also a three-level step, a four-level step, etc., and this embodiment does not limit this.

[0050] Similarly, the cross-section of the second steel bar 32 is in a stepped shape. The installation method of the second steel bar 32 and the second installation groove 122 refers to the description of the first steel bar 31 and the first installation groove 121 above, so it will not be elaborated here.

[0051] In the second specific embodiment, the cross-section of the first steel bar 31 is in an isosceles trapezoid shape.

[0052] For example, as Figure 6 and Figure 7 shown, the cross-section of the first steel bar 31 is in an isosceles trapezoid shape, including a first bottom surface 313, a second bottom surface 314, and a first side surface 315 and a second side surface 316 connecting the first bottom surface 313 and the second bottom surface 314. The first bottom surface 313 is arranged in the first installation groove 121, the first upper stop portion 1211 stops or limits the first side surface 315, and the first lower stop portion 1212 stops or limits the second side surface 316, realizing the stable insertion of the first steel bar 31 into the first installation groove 121.

[0053] As Figure 7 shown, the second bottom surface 314 protrudes from the notch of the first installation groove 121. Since both the first upper stop portion 1211 and the first lower stop portion 1212 are located at the notch of the first installation groove 121, and the second bottom surface 314 abuts against the first bearing 21, there is a gap d2 in the left-right direction between the first upper stop portion 1211, the first lower stop portion 1212 and the second bottom surface 314. When the frame 11 moves vertically, there is the above-mentioned gap d2 in the left-right direction between the first bearing 21 and the first upper stop portion 1211, the first lower stop portion 1212, thus avoiding the risk of collision between the first bearing 21 and the first upper stop portion 1211, the first lower stop portion 1212, and further contributing to the stable setting of the first steel bar 31 in the first installation groove 121.

[0054] Of course, it can be understood that the first steel bar 31 can be not only in the shape of an isosceles trapezoid, but also in the shape of a diameter trapezoid, a non-isosceles trapezoid, etc. This embodiment does not limit this.

[0055] Similarly, the cross-section of the second steel bar 32 is in the shape of an isosceles trapezoid. For the installation method of the second steel bar 32 and the second installation groove 122, refer to the description of the first steel bar 31 and the first installation groove 121 above, so it will not be elaborated here.

[0056] Among them, in the first and second specific embodiments, the first bearing 21 and the second bearing 22 are the same, and the thickness of the first bearing 21 and the second bearing 22 is between 6 mm and 12 mm, including 6 mm and 12 mm.

[0057] In the third specific embodiment, a first protrusion 211 is provided on the side wall of the first bearing 21, and a second protrusion 221 is provided on the side wall of the second bearing 22.

[0058] For example, as Figure 8 and Figure 9 shown, in the middle region of the side wall of the first bearing 21 in the vertical direction, a ring-shaped first protrusion 211 is formed by protruding along its circumferential direction. Thus, the side wall of the first bearing 21 includes a first upper side wall 213, a first lower side wall 214, and a first middle side wall 212 located between the first upper side wall 213 and the first lower side wall 214. Among them, the first middle side wall 212 is part of the first protrusion 211, and the first middle side wall 212 is in contact with the first steel bar 31.

[0059] As Figure 9 shown, since the diameter d4 of the first protrusion 211 in the left-right direction is greater than the size of the first upper stop 1211 (or the first lower stop 1212) in the left-right direction, that is, the distance between the first middle side wall 212 and the first upper side wall 213 (or the first lower side wall 214) is greater than the size of the first upper stop 1211 (or the first lower stop 1212) in the left-right direction. In this way, there is a gap d3 between the first upper side wall 213 and the first upper stop 1211 in the left-right direction, and there is a gap d3 between the first lower side wall 214 and the first lower stop 1212 in the left-right direction.

[0060] When the frame 11 moves up and down in the vertical direction, there is the above-mentioned gap d3 between the first bearing 21 and the first upper stop 1211 and the first lower stop 1212 in the left-right direction, thus avoiding the risk of collision between the first bearing 21 and the first upper stop 1211 and the first lower stop 1212, and further helping the first steel bar 31 to be stably arranged in the first installation groove 121.

[0061] Of course, it can be understood that the side wall of the first bearing 21 bulges to form a first convex portion 211 in the middle region in the vertical direction. The first convex portion 211 may not be annular and may have other suitable shapes, and this embodiment does not limit this.

[0062] Similarly, in the middle region of the side wall of the second bearing 22 in the vertical direction, a ring-shaped second convex portion 221 is formed by bulging along its circumferential direction. The second convex portion 221 has the same structure as the first convex portion 211. Referring to the description of the first convex portion 211 above, it will not be elaborated here.

[0063] Among them, as Figure 9 shown, the thickness dimension of the first convex portion 211 and the second convex portion 221 is L1, that is to say, the dimension of the first convex portion 211 and the second convex portion 221 in the vertical direction is L1, and 6 mm ≤ L1 ≤ 7 mm.

[0064] Furthermore, as Figure 9 shown, the thickness of both the first bearing 21 and the second bearing 22 is L2, and 8 mm ≤ L2 ≤ 12 mm. By increasing the thickness of the first bearing 21 and the second bearing 22, the load-bearing capacity of the bearing can be improved, which helps the first bearing 21 and the second bearing 22 slide along the guide rail 12 smoothly.

[0065] In practical applications, the thickness of the first bearing 21 and the second bearing 22 is usually between 6 mm and 7 mm, including 6 mm and 7 mm. However, in this embodiment, the thicknesses of both the first bearing 21 and the second bearing 22 are greater than 7 mm, which improves the load-bearing capacity of the first bearing 21 and the second bearing 22 and helps to extend the service life of the first bearing 21 and the second bearing 22.

[0066] In practical applications, the first bearing 21 and the second bearing 22 are double-row bearings, for example, double-row ball bearings.

[0067] Taking the first bearing 21 as an example, the first bearing 21 includes a first upper bearing and a first lower bearing that are connected to each other, and the first upper bearing and the first lower bearing have the same thickness. In this way, the thicknesses of both the first upper bearing and the first lower bearing are less than or equal to 6 mm, and existing technology bearings can be borrowed, thereby reducing the processing difficulty of the first bearing 21 and the processing cost of the first bearing 21; at the same time, the forces received by the first upper and lower bearings are both half of the force applied by the frame 11, and the forces on the first upper and lower bearings are reduced, which helps to extend the service life of the first bearing 21.

[0068] The example of the present utility model also provides a computerized embroidery machine, including the above-mentioned embroidery frame assembly.

[0069] This computerized embroidery machine has the advantages of the embroidery frame assembly, so it will not be elaborated here.
