The connecting block includes a first connecting plate and a second connecting plate, the first connecting plate is arranged between the top plate and the corresponding track, and is connected to the top plate, one end of the first connecting plate is provided with a first buckle extending downward and used to engage with a slot on one side of the corresponding track, the first connecting plate extends from above the corresponding track to the outside of the corresponding track, the second connecting plate is arranged below the part of the first connecting plate located outside the corresponding track, the second connecting plate is rotatably connected to the first connecting plate by a longitudinally extending screw and can be locked, and one end of the second connecting plate is provided with a second buckle for engaging with the slot on the other side of the corresponding track.

[0004] It can be seen that in the prior art, when installing the curtain track, an L-shaped mounting bracket and two connecting blocks (which are actually split connecting pieces) are used in conjunction with the mounting track.

[0005] When installing the track, the operator usually installs the mounting bracket on the wall (side wall or top wall), and pre-installs a part of the connector with the track. At this time, since the track is long, the operator needs to hold the track to keep it in a horizontal state, and then install the other part of the connector so that the mounting bracket matches the connector and the track, and can complete the installation by drilling holes with screws and other matching parts. The above installation process requires two people to operate the installation because the operator needs to hold the track all the time and assemble it with screws, which is inconvenient for one person to operate the installation. Utility Model Content

[0006] The technical problem to be solved by the utility model is to enable installers to install the track without having to hold the track all the time, and to provide a mounting bracket which is relatively easy to install.

[0014] Furthermore, the number of the second matching pieces is two, and the two second matching pieces are located at opposite corners of the main body.

[0015] Furthermore, the track includes an inner track and an outer track, wherein the inner track is slidably connected to the outer track;

[0016] The connecting piece connected to the inner rail has a first height difference between the second matching piece thereon and the assembly portion; the connecting piece connected to the outer rail has a second height difference between the second matching piece thereon and the assembly portion; the first height difference is greater than the second height difference.

[0017] The utility model also provides a track connected with the connecting assembly or the mounting bracket.

[0018] On the basis of conforming to the common sense in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present utility model.

[0019] The positive progressive effect of the utility model is that by arranging a first matching piece on the top plate, a first supporting space is formed between the first matching piece and the top plate, and a connecting piece or a track slides into the first supporting space, and the track is supported by the first supporting space.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one" do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0037] like Figure 1-14 As shown, the utility model discloses a mounting bracket 100, comprising a top plate 110; at least one first matching member 120, disposed on the top plate 110;

[0038] A first supporting space S1 is defined between the first matching member 120 and the top plate 110 , and at least a portion of the rail 300 or the connecting member 200 is located in the first supporting space S1 , so that the first supporting space S1 supports the rail 300 or the connecting member 200 .

[0039] In this embodiment, the mounting bracket 100 is a prior art, which is L-shaped as a whole and includes a top plate 110. The top plate 110 is used to support the rail 300 when it is installed on the top. The top plate 110 cooperates with the top wall to realize the installation of the mounting bracket 100. The length of the top plate 110 can be configured according to the corresponding number of rails 300, that is, when there is one rail 300, the length of the top plate 110 is adapted to the width of one rail 300; when there are two rails 300, the length of the top plate 110 is adapted to the width of the two rails 300 and the gap between the two rails 300. According to the actual number of rails 300, top plates 110 of different lengths (mounting brackets 100 of different models) can be matched accordingly.

[0040] The mounting bracket 100 also includes a mounting plate 111, which is connected to the top plate 110. The mounting plate 111 is used to support the rail 300 when it is installed on the side. The mounting plate 111 cooperates with the side wall to realize the installation of the mounting bracket 100. The mounting plate 111 is provided with holes for screws, bolts and other fixed connections to pass through. Preferably, an arc-shaped portion can be used to transition between the mounting plate 111 and the top plate 110. The setting of the arc-shaped portion makes it difficult for operators to cut their hands when using the mounting bracket 100. Preferably, the mounting plate 111 and the top plate 110 are an integrated piece to ensure the strength of the mounting plate 111 and the top plate 110. Please refer to the following. Figure 2-5 The one-piece mounting bracket 100 can be applied to different installation scenarios of single track and double track. Of course, the mounting plate 111 and the top plate 110 can also be set separately, and the mounting plate 111 and the top plate 110 can be fixedly connected by welding or other fixed connection methods in the later stage. The separate setting is easy to manufacture.

[0041] The first matching member 120 is disposed on the side of the top plate 110 facing the track 300, that is, Figure 2-5 As shown, the first matching member 120 is located below the top plate 110. A support space is formed between the first matching member 120 and the top plate 110, that is, there is a gap between the first matching member 120 and the top plate 110, and the gap is used to accommodate the connecting member 200 or a part of the structure on the track 300 for support. Preferably, the first matching member 120 and the top plate 110 are an integral part, such as Figure 2-3 As shown, a cutout is provided on the top plate 110. Of course, the top plate 110 and the first matching member 120 can also be provided separately, and then connected by a fixed connection method such as welding.

[0042] Preferably, two first matching pieces 120 are used, which are respectively arranged at two ends of the lower surface of the top plate 110, that is, the two first matching pieces 120 and the lower surface of the top plate 110 form a first supporting space S1, and the corresponding rail 300 or connecting piece 200 partially fills the first supporting space S1.

[0043] When the first supporting space S1 is used to support the track 300, the mounting bracket 100 is first slid onto the track 300, and then the mounting bracket 100 and the track 300 are assembled together onto the wall. Correspondingly, in order to ensure that the mounting bracket 100 can be installed into the track 300, the two first matching pieces 120 are symmetrically arranged about the center of the top plate 110.

[0044] Those skilled in the art will know that, since the track 300 is long, multiple installation brackets 100 are required to be arranged at intervals, for example, four installation brackets 100. The installation brackets 100 are first installed on the wall, and when the first support space S1 is used to support the connector 200, the connector 200 is pre-slid onto the track 300, and then the first support space S1 corresponds to the connector 200, so that the first support space S1 in the four installation brackets 100 corresponds to the connector 200 on the track 300. At this time, since the first support space S1 supports the connector 200 and the track 300, it is ensured that the connector 200 and the track 300 will not fall or tilt due to their own weight, and the operator does not need to hold the track 300 all the time, which can free the operator's hands, and then the operator fixes the connector 200 and the installation bracket 100 with screws, etc. to complete the installation. By supporting the track 300 through the first support space S1, the operator does not need to hold the track 300 all the time, and only one person is required to operate the installation, which significantly reduces the labor cost and has practical promotion significance.

[0045] refer to Figure 2-5 As shown, specifically, it also includes a support portion 121 , which is connected to the first matching member 120 , and is used to support at least a portion of the track 300 or the connecting member 200 .

[0046] The support portion 121 is connected to the first matching member 120. The support portion 121 may be a part of the first matching member 120. The support portion 121 may preferably be a support plate. During assembly, the height of the support portion 121 is lower than the height of the connecting member 200 or the height of the track 300 to ensure that after the connecting member 200 or the partial structure on the track 300 slides into the first supporting space S1, the connecting member 200 leans on the support portion 121, and the support portion 121 plays a supporting role. Fig.12 , 13As shown, the height of the support portion 121 is slightly smaller than the height of the highest point of the connector 200 or the height of the highest point of the track 300, that is, the upper surface of the support portion 121 is in contact with the lower surface of the highest point of the connector 200, or the upper surface of the support portion 121 is in contact with the lower surface of the highest point of the track 300. This ensures that the operator does not need to hold the track 300 all the time, and when the track 300 falls under its own weight, the support portion 121 contacts the connector 200 or the track 300 to form a support effect.

[0047] The support portion 121 is connected to the first matching piece 120. The support portion 121 and the first matching piece 120 are different components. The support portion 121 can also be a screw, etc., and the screw serves as the support portion 121, that is, the first matching piece 120 is provided with a through hole for the screw to pass through, and the corresponding connecting piece 200 or the rail 300 has a through hole, and the screw passes through the above-mentioned through hole to achieve the function of the support portion 121.

[0048] refer to Figure 2-5 , 12, 13. Specifically, the first matching member 120 includes a transition portion 131, and the transition portion 131 and the support portion 121 are integrally formed.

[0049] The first matching piece 120 is specifically a first hook 130 . Preferably, two first matching pieces 120 , ie, two first hooks 130 , are disposed on the top plate 110 .

[0050] When the mounting bracket 100 is directly matched with the track 300 , the distance between the two first hooks 130 is matched with the width of the track 300 to ensure that the two first hooks 130 can be inserted into the grooves of the track 300 .

[0051] When the mounting bracket 100 cooperates with the connecting member 200, the distance between the two first hooks 130 is adapted to the width of the connecting member 200, and both ends of the connecting member 200 are inserted into the first supporting space S1. Specifically, the connecting member 200 is inserted into the track 300 by first rotating it at a certain angle to insert it into the groove of the track 300, and then rotating it back at a certain angle to complete the installation with the track 300.

[0052] The transition portion 131 can specifically be a vertical plate, or an inclined plate, which is an integral part with the top plate 110. The vertical height of the transition portion 131 is slightly larger than the thickness of the connector 200 (when matched with the connector 200) or the thickness of the groove of the track 300 (when matched with the track 300), thereby ensuring that the mounting bracket 100 can achieve a tight fit with the connector 200 or the track 300 when matched, and ensuring that the connector 200 or the track 300 does not shake up and down.

[0053] The support portion 121 can be a hook or a flat plate, which is specifically adapted to the two ends of the connector 200 or the two ends of the track 300. A flat plate is preferred, as the flat plate has a relatively uniform force-bearing surface and has a good supporting force, and can support the connector 200 or the track 300. The support portion 121 and the transition portion 131 are an integral part. In combination, as the most preferred solution: the top plate 110 and the mounting plate 111 are integrated, the support portion 121 and the transition portion 131 are integrated, and the first matching member 120 and the top plate 110 are integrated.

[0054] refer to Figure 6-9 As shown in FIG. 14 , specifically, a plurality of first connection holes 140 are provided on the top plate 110 , and the first connection holes 140 and the support portion 121 are staggered.

[0055] Since the connection piece 200 and the top plate 110 need to be fixedly connected by screws, the screws need to pass through the top plate 110 and the connection piece 200 in sequence and be fixed on the wall. In this embodiment, the first connection hole 140 and the support portion 121 of the first matching piece 120 are staggered to ensure that the screw will not pass through the support portion 121, to ensure the integrity of the support portion 121, and not to cause subsequent metal fatigue and other phenomena due to the screw holes on the support portion 121. Specifically, the width of the support portion 121 is smaller than the width of the two ends of the connection piece 200, one end of the support portion 121 is arranged against the middle of the two ends of the connection piece 200, and the first connection hole 140 is arranged on both sides of the two ends of the connection piece 200, thereby forming a staggered arrangement on the vertical plane.

[0056] refer to Figure 1-9 As shown, the utility model further discloses a connection assembly, including a mounting bracket 100 and a connection member 200 , wherein at least one end of the connection member 200 is matched with a first matching member 120 .

[0057] The connecting component includes the above-mentioned mounting bracket 100 and connecting member 200. When side installation is required, the mounting bracket 100 and connecting member 200 need to be installed in coordination; when top installation is required, the mounting bracket 100 and connecting member 200 can be installed in coordination, or the connecting member 200 can be directly used for installation. Installation using the connecting member 200 is an existing technology and will not be repeated here.

[0058] The connecting member 200 is preferably a slide plate, and the slide plate can be any slide plate in the prior art. Preferably, the slide plate connecting member 200 is pre-slid into the track 300. The specific way in which the connecting member 200 is inserted into the track 300 is consistent with the way in which the above-mentioned mounting bracket 100 is installed into the track 300. First, rotate it a certain angle to insert it into the groove of the track 300, and then rotate it a certain angle to complete the installation of the track 300.

[0059] Among them, one end of the connector 200 slides into the first support space S1, and the corresponding other end can be fixed with a fixing tool such as a screw, and the first support space S1 can also achieve a supporting effect. Preferably, both ends of the connector 200 slide into the first support space S1, and the connector 200 at least partially fills the first support space S1. Preferably, the center line of the top plate 110 is consistent with the center line of the connector 200, so as to ensure the balance of the connector 200 and the balance of the track 300 matched with the connector 200.

[0060] refer to Figure 4-9 As shown, specifically, the connecting member 200 includes: at least one second matching member 210, which is arranged on the connecting member 200, and a second supporting space S2 is provided between the second matching member 210 and the connecting member 200, and at least a part of the rail 300 is located in the second supporting space S2, so that the second supporting space S2 forms a support for the rail 300.

[0061] The second matching member 210 and the connecting member 200 are an integral part. Figure 6-9 As shown, a cutting opening is provided on the connecting member 200, and a gap is provided at the connection between the second matching member 210 and the top plate 110. Of course, the connecting member 200 and the second matching member 210 may also be provided separately and then connected by a fixed connection method such as welding. The separate setting is easy to manufacture.

[0062] Similarly, a second supporting space S2 may be formed between the second matching member 210 and the connecting member 200. The second supporting space S2 is used to support the track 300. The track 300 is provided with a groove for the second matching member 210 to be inserted. Figure 6-7 The second matching member 210 includes a second hook 220, which is inserted into a groove on the track 300. The second hook 220 can also adopt the same structure as the first hook 130, which will not be repeated here.

[0063] refer to Figure 6-9 As shown, specifically, the connector 200 includes: a main body 230; an assembly portion 240, the assembly portion 240 is connected to the main body 230, and a second connection hole 241 is provided on the assembly portion 240; wherein, preferably, the second connection hole 241 is provided corresponding to the first connection hole 140.

[0064] The number of the assembly parts 240 is preferably two, and the two assembly parts 240 are connected to both sides of the main body 230. The assembly part 240 and the main body 230 are preferably an integral part. Of course, the assembly part 240 and the main body 230 can also be separately arranged, and then fixed by welding or other methods. The assembly part 240 is provided with a second connection hole 241, and the second connection hole 241 is used for screws, bolts and other fixing parts to pass through. The second connection hole 241 cooperates with the first connection hole 140 so that the screws, bolts and other fixing parts pass through the first connection hole 140 and the second connection hole 241, thereby ensuring the connection between the connecting member 200 and the top plate 110. In order to ensure the connection between the connecting member 200 and the top plate 110, the first connection hole 140 and the second connection hole 241 can preferably adopt waist-shaped holes. The setting of the waist-shaped holes allows screws and bolts to pass through different positions on the waist-shaped holes to meet different installation requirements.

[0065] A relatively smooth portion is used for transition between the main body portion 230 and the assembly portion 240, which is easy to process and manufacture.

[0066] Specifically, there are two second matching pieces 210 , and the two second matching pieces 210 are located at opposite corners of the main body 230 .

[0067] The two second matching pieces 210 are arranged at the diagonal positions of the main body 230. The diagonal position here is an oblique line passing through the main body 230. The two second matching pieces 210 are arranged at the diagonal positions of the oblique line. Preferably, the oblique line is a diagonal line. This ensures that when the connector 200 is installed in the track 300, it can be rotated a certain angle to be inserted into the groove of the track 300, and then rotated back a certain angle to complete the installation of the track 300. Figure 6 As shown, the two second mating parts 210 are offset by the same distance to one side of the first direction and the second direction respectively compared to the horizontal line L, and the first direction and the second direction are both horizontally perpendicular to the horizontal line L, and the two directions are opposite, ensuring that the connecting part 200 can be more conveniently installed in the track 300.

[0068] Specifically, the track 300 includes an inner rail 310 and an outer rail 320, the inner rail 310 is slidably connected to the outer rail 320; the connecting piece 200 connected to the inner rail 310 has a first height difference H1 between the second matching piece 210 thereon and the assembly part 240; the connecting piece 200 connected to the outer rail 320 has a second height difference H2 between the second matching piece 210 thereon and the assembly part 240; the first height difference H1 is greater than the second height difference H2.

[0069] The inner rail 310 is provided with a first slot 330, and the outer rail 320 is provided with a second slot 340. Therefore, there is an initial height difference H3 between the first slot 330 and the second slot 340, and the difference between the first height difference H1 and the second height difference H2 is slightly greater than the initial height difference H3 between the first slot 330 and the second slot 340. It is ensured that the assembly portion 240 on the connector 200 is at the same level after being assembled into the inner rail 310 and the outer rail 320, so that the connector 200 is conveniently connected to the mounting bracket 100 at the same level.

[0070] refer to Figure 1 , 9 As shown in FIG. 13 , the utility model further discloses a track 300 connected with a connecting assembly or a mounting bracket 100 .

[0071] The track 300 of the utility model also includes a connection assembly and a mounting bracket 100. The connection assembly includes a combination of a connection member 200 and a mounting bracket 100. The mounting bracket 100 is to use only a plurality of mounting brackets 100 to complete the installation of the track 300. Of course, when only top installation is required, multiple connection members 200 can also be used for installation. The types of tracks 300 include single track, double track, telescopic track, curved track (special-shaped track), etc. The length of the top plate 110 in the corresponding mounting bracket 100 will have different sizes according to the different types of tracks 300, and the corresponding specifications of the mounting bracket 100 are different, so as to facilitate one-to-one matching during subsequent installation.

[0072] When the utility model is applied to the assembly of the electric curtain track 300, transmission boxes are installed on both sides of the track 300 for installing the transmission components.
