Description

Technical Field

[0001] This application relates to the field of hardware accessories technology, and more specifically, to a detachable hanging bracket pulley. Background Technology

[0002] Hanging pulleys are commonly used on sliding doors in balconies, kitchens, and dining rooms. They are an important component of sliding doors and play a role in buffering the closing process. They suspend the door leaf and support the weight of the door on the wheels, working in harmony with the hanging rail to allow the door to move easily.

[0003] To facilitate the assembly of the hanging pulley with the guide rail, the width of the hanging pulley is designed to be greater than the width of the guide rail groove, thus increasing the difficulty of installation. In existing technology, to solve this problem, many different types of detachable hanging pulleys have emerged on the market. For example, Chinese invention patent CN115059367A—A Hanging Pulley and its Usage Method—discloses a detachable hanging pulley, including a fixed base body and a detachable hanging bracket body. The detachable hanging bracket body is engaged with the base body by a positioning shaft located at the bottom of the detachable hanging bracket body and a positioning groove opened at the top of the base body, allowing for free assembly and disassembly. However, in actual installation, this structure has a small contact area between the positioning shaft and the positioning groove, resulting in unstable connection. Furthermore, because the detachable hanging bracket is fixed above the bottom of the base body, its overall structure is large in the vertical direction, making it prone to interference with the guide rail during assembly and disassembly. Therefore, existing detachable hanging pulley structures suffer from large size and insufficient overall structural stability.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0005] The purpose of this application is to provide a detachable hanging bracket pulley, which has the advantages of small size, easy disassembly and assembly, and stable structure.

[0006] Firstly, this application provides a detachable hanging bracket pulley, the technical solution of which is as follows:

[0007] The fixed base includes a first crossbar, a second crossbar, and a support rod.

[0008] The support rod is positioned between the first crossbar and the second crossbar, and cooperates with the first crossbar and the second crossbar to form two first cavities on the left and right. The end of the first cavity is connected to the outside, and a first limiting part is provided on the first cavity opposite to the support rod.

[0009] The detachable hanger is slidably connected to the fixed base and includes a first movable part and a second movable part. The first movable part and the second movable part are respectively provided with a first protrusion that is slidably connected to a first cavity. The first protrusion is provided with a first groove, which is used to cooperate with a first limiting part so that the detachable hanger is slidably engaged with the fixed base.

[0010] By dividing the detachable hanging bracket pulley into two parts—a fixed base and a detachable hanging bracket—the hanging bracket pulley is made easier to disassemble. The fixed base includes a first crossbar, a second crossbar, and a support rod. The support rod is positioned between the first and second crossbars and cooperates with the first and second crossbars to form two left and right first cavities, making the cross-section of the fixed base form an "I" shape. The ends of the first cavities are open to the outside, facilitating the insertion of the detachable hanging bracket into the fixed base and its sliding connection with the fixed base. The first cavities are provided with first limiting parts opposite to the support rods. The first limiting parts are used to limit the detachable hanging bracket inserted into the fixed base, preventing the detachable hanging bracket from falling off the left and right sides of the "I" shaped structure of the fixed base. This structure has... Strong stability; the detachable hanger is slidably connected to the fixed base through the first groove cavity, including a first movable part and a second movable part, dividing the detachable hanger into two parts, which can be detached from or installed on the fixed base respectively, further improving the flexibility of the overall detachable hanger pulley for disassembly and assembly. The first movable part and the second movable part are respectively provided with a first protrusion that is slidably connected to the first groove cavity. The first protrusion is provided with a first groove, which is used to cooperate with the first limiting part, so that the detachable hanger is slidably engaged on the fixed base. Through this setting, the detachable hanger can be pushed into the fixed base through the end of the first groove cavity, fixing the detachable hanger to both sides of the fixed base, reducing the volume of the overall structure in the vertical direction, and making disassembly and assembly more convenient.

[0011] Furthermore, in some technical solutions, the horizontal dimension of the first crossbar is smaller than that of the second crossbar in the cross-section of the fixed base.

[0012] By setting the length of the first crossbar to be less than the length of the second crossbar in the cross-section of the fixed base, the first detachable hanger, after being inserted into and connected to the fixed base, has a second cavity between the first crossbar and the detachable hanger. This cavity accommodates the fixing bolt of the pulley, preventing the fixing bolt of the pulley from contacting the fixed base during the sliding assembly and disassembly of the detachable hanger, thus allowing the detachable hanger to slide better on the fixed base.

[0013] Furthermore, in some technical solutions, the first movable part and the second movable part are respectively provided with a second protrusion, the second protrusion is disposed above the first protrusion and forms a second groove with the first protrusion, the second groove is used to accommodate the first crossbar.

[0014] By providing second protrusions on the first movable part and the second movable part respectively, the second protrusions are positioned above the first protrusions and form a second groove with the first protrusions. The second groove is used to accommodate the first crossbar, making the snap-fit ​​structure between the detachable hanger and the fixed base more stable.

[0015] Furthermore, in some technical solutions, pulleys are respectively connected to the outer sides of the first movable part and the second movable part, and a second groove is provided in the second groove. The second groove is used to accommodate the fixing bolt of the pulley. The fixing bolt is used to pass through the pulley and the first movable part and the pulley and the second movable part respectively, and fix the pulley to the first movable part and the second movable part respectively.

[0016] By connecting pulleys to the outer sides of the first movable part and the second movable part respectively, and providing a second groove in the second groove, the second groove is used to accommodate the fixing bolt of the pulley. After the fixing bolt fixes the pulley to the first movable part and the second movable part, the end is placed in the second groove. When sliding, it will not collide with the first crossbar, so that the detachable bracket and the fixed base can be slidably connected.

[0017] Furthermore, in some technical solutions, the ends of the first movable part and the second movable part are respectively provided with hand-held push-pull parts, which are respectively arranged perpendicularly to the first movable part and the second movable part, forming an inverted "L" shape.

[0018] Furthermore, in some technical solutions, the bottom of the handheld push-pull part is provided with a push-pull insertion hole for inserting a tool to push the first movable part and / or the second movable part into the fixed base, or pull it out from the fixed base.

[0019] Furthermore, in some technical solutions, a third groove is provided at one end of the first movable part and the second movable part near the hand-held push-pull part. After the first movable part and the second movable part are combined, the two third grooves form a third cavity. A first through hole is provided on the fixed base corresponding to the third cavity. The first through hole communicates with the third cavity and is used to install screws to fix the fixed base and the detachable bracket.

[0020] Furthermore, in some technical solutions, a second through hole is provided in the middle of the fixed base for mounting a screw.

[0021] Furthermore, in some technical solutions, the first movable part and the second movable part are respectively provided with a fourth groove recessed in the direction of the pulley. The outer surface of the fourth groove is arc-shaped and protrudes, and the distance of the protrusion is less than the distance between the pulley and the first movable part or the second movable part.

[0022] Furthermore, in some technical solutions, after the first movable part and the second movable part are combined, the two fourth grooves form a fourth cavity, and the fourth cavity is connected to the second through hole for setting the screw.

[0023] As can be seen from the above, the detachable hanging pulley provided in this application divides the detachable hanging pulley into two parts: a fixed base and a detachable hanging bracket. This makes the hanging pulley easier to disassemble. The fixed base includes a first crossbar, a second crossbar, and a support rod. The support rod is located between the first and second crossbars and cooperates with the first and second crossbars to form two left and right first cavities, making the cross-section of the fixed base form an "I" shape. The ends of the first cavities are connected to the outside, facilitating the insertion of the detachable hanging bracket into the fixed base through the first cavities and its sliding connection with the fixed base. The first cavities are provided with a first limiting part opposite to the support rod. The first limiting part is used to limit the detachable hanging bracket inserted into the fixed base, preventing the detachable hanging bracket from slipping out of the left side of the "I" shaped structure of the fixed base. The right sides detach, demonstrating the structure's strong stability. The detachable hanger is slidably connected to the fixed base via a first groove, comprising a first movable part and a second movable part, dividing the detachable hanger into two parts. These two parts can be detached from or installed on the fixed base separately, further improving the flexibility of the overall detachable hanger pulley. The first and second movable parts are each provided with a first protrusion that slidably connects to the first groove. The first protrusion has a first groove that engages with a first limiting part, allowing the detachable hanger to slide and engage with the fixed base. This design allows the detachable hanger to be pushed into the fixed base through the end of the first groove, fixing it to both sides of the fixed base and reducing the overall vertical volume of the structure, making assembly and disassembly more convenient. Therefore, this detachable hanger pulley offers the advantages of small size, easy assembly and disassembly, and structural stability. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] Currently, many detachable hanging pulleys have appeared on the market to facilitate better assembly. However, these detachable pulleys are not convenient to disassemble and assemble, and their installation lacks sufficient stability. To solve this problem, this application proposes a detachable hanging bracket pulley.

[0039] For this, please refer to Figures 1 to 11 A detachable hanging bracket pulley, the technical solution of which is as follows:

[0040] The fixed base 110 includes a first crossbar 111, a second crossbar 112, and a support rod 113.

[0041] The support rod 113 is disposed between the first crossbar 111 and the second crossbar 112, and cooperates with the first crossbar 111 and the second crossbar 112 to form two first cavities 114 on the left and right. The end of the first cavity 114 is connected to the outside. A first limiting part 115 opposite to the support rod 113 is provided on the first cavity 114.

[0042] The detachable hanger 120 is slidably connected to the fixed base 110 and includes a first movable part 121 and a second movable part 122. The first movable part 121 and the second movable part 122 are respectively provided with a first protrusion 123 that is slidably connected to the first cavity 114. The first protrusion 123 is provided with a first groove 124, which is used to cooperate with the first limiting part 115 so that the detachable hanger 120 is slidably engaged on the fixed base 110.

[0043] In practical applications, the fixed base 110 is connected to the guide rail by screws 118, and the detachable bracket 120 is slidably snapped onto the fixed base 110 and can be removed by pulling. The two sides of the detachable bracket 120 are connected to the pulleys 130 by fixing bolts 131.

[0044] Please refer to Figures 1 to 3The fixed base 110 includes a first crossbar 111, a second crossbar 112, and a support rod 113. In practical applications, the entire structure of the fixed base 110 is made of metal. In some preferred embodiments, the first crossbar 111 and the second crossbar 112 can be arranged parallel to each other in the horizontal direction, with the first crossbar 111 positioned above the second crossbar 112 to ensure the flatness of the upper and lower sides of the fixed base 110 and facilitate installation in the guide rail. The support rod 113 is positioned between the first crossbar 111 and the second crossbar 112, and cooperates with the first crossbar 111 and the second crossbar 112 to form two first cavities 114 on the left and right sides. In some preferred embodiments, the support rod 113 can be vertically arranged between the first horizontal bar 111 and the second horizontal bar 112. This structure makes the cross-section of the fixed base 110 "I". Since the first horizontal bar 111 and the second horizontal bar 112 are parallel in the horizontal direction, the first cavity 114 formed after cooperating with the vertically arranged support rod 113 is a straight cavity, which makes it easy for the detachable hanger 120 to be inserted into the fixed base 110 through the first cavity 114 or pulled out of the fixed base 110 without interfering with the fixed base 110. Furthermore, fixing the detachable hanger 120 to both sides of the fixed base 110 can reduce the volume of the overall structure and make disassembly and assembly more convenient.

[0045] In this design, the end of the first cavity 114 is connected to the outside. In practical applications, both ends of the first cavity 114 can be connected to the outside, which facilitates the detachable hanger 120 being pushed in or pulled out. However, this structure, where both ends are connected to the outside, may result in the detachable hanger 120 being pushed in from one end of the first cavity 114 and pushed out from the other end. Therefore, in order to solve this problem, in some preferred embodiments, a limiting part can be provided at one end of the first cavity 114. In cross-section, the dimension of the limiting part in the horizontal direction is larger than the dimension of the first cavity 114 in the horizontal direction. This ensures that after the detachable hanger 120 is pushed in from one end, it abuts against the limiting part, avoiding the problem of the detachable hanger 120 being pushed out from the other end of the first cavity 114, thus making the detachable hanger pulley 100 structure more stable. Since the first cavity 114 is formed by the cooperation of the first crossbar 111, the second crossbar 112 and the support rod 113, it only has a three-sided enclosed structure with an "I"-shaped cross section. Therefore, there is a risk that the detachable hanger 120 may fall off from the two sides of the "I" shape after being inserted into the first cavity 114, which is not conducive to the stability of the detachable hanger 120 installation. To solve this problem, a first limiting part 115 opposite to the support rod 113 can be provided on the first cavity 114, so that the first cavity 114 has a four-sided enclosed structure. However, the four-sided enclosed structure is not suitable for inserting the detachable hanger 120. Therefore, in some preferred embodiments, the length of the first limiting part 115 can be set to be less than the length of the support rod 113, so that after the detachable hanger 120 is inserted into the first cavity 114, it is engaged with the fixed base 110 through the first limiting part 115, making the installation structure more stable. In some embodiments, the first limiting part 115 on the first cavity 114 may be disposed on the first crossbar 111 and pointing towards the second crossbar 112, or disposed on the second crossbar 112 and pointing towards the first crossbar 111, or disposed on the first crossbar 111 and the second crossbar 112 respectively, with opposite directions, so as to improve the stability of the detachable bracket 120 connected to the fixed base 110.

[0046] In practical applications, the detachable hanger 120 is slidably connected to the fixed base 110. To ensure the stability of the connection, the detachable hanger 120 is engaged with the fixed base 110 via the first groove 114 and the first limiting part 115. The detachable hanger 120 includes a first movable part 121 and a second movable part 122, and the first movable part 121 and the second movable part 122 are respectively provided with a first protrusion 123 that is slidably connected to the first groove 114. In order to make the detachable hanger 120 better cooperate and slide with the first groove 114, the first protrusion 123 can be provided to slide in contact with the first groove 114, making the installation and removal of the detachable hanger 120 smoother and more convenient. When removing the detachable hanger 120, it is only necessary to pull it out from the first groove 114 on both sides of the fixed base 110, which improves the convenience of assembling and disassembling the detachable hanger 120. In order to better engage the detachable bracket 120 with the fixed base 110, a first groove 124 is provided on the first protrusion 123. The first groove 124 is used to cooperate with the first limiting part 115 to make the engagement structure more stable.

[0047] Furthermore, in some preferred embodiments, in the cross-section of the fixed base 110, the horizontal dimension of the first crossbar 111 is smaller than the horizontal dimension of the second crossbar 112.

[0048] In practical applications, since the detachable bracket 120 is mounted on the fixed base 110, and pulleys 130 are connected to both sides of the detachable bracket 120, the pulleys 130 are connected to the first movable part 121 and the second movable part 122 of the detachable bracket 120 respectively through fixing bolts 131. Therefore, the fixing bolts 131 pass through the pulleys 130 and the first movable part 121, and the pulleys 130 and the second movable part 122 respectively. In order to ensure that the part of the fixing bolt 131 after passing through the pulleys 130 and the detachable bracket 120 will not interfere with the fixed base 110 when sliding with the detachable bracket 120, the horizontal dimension of the first crossbar 111 can be smaller than the horizontal dimension of the second crossbar 112, so that there is sufficient space between the first crossbar 111 and the first movable part 121 and the second movable part 122 respectively to accommodate the fixing bolts 131.

[0049] Furthermore, in some preferred embodiments, the first movable part 121 and the second movable part 122 are respectively provided with a second protrusion 125, the second protrusion 125 is disposed above the first protrusion 123, and forms a second groove 126 with the first protrusion 123, the second groove 126 is used to accommodate the first crossbar 111.

[0050] Please refer to Figures 4 to 6In practical applications, to enable the detachable bracket 120 to engage more stably with the fixed base 110, a second protrusion 125 is provided above the first protrusion 123. A second groove 126 is formed between the second protrusion 125 and the first protrusion 123. The second groove 126 is used to accommodate the first crossbar 111. Through this structure, the first protrusion 123 on the detachable bracket 120 engages with the first cavity 114 on the fixed base 110, and the first crossbar 111 on the fixed base 110 engages with the second groove 126 on the detachable bracket 120. The two engage with each other, improving the stability of the connection.

[0051] Furthermore, in some preferred embodiments, pulleys 130 are respectively connected to the outer sides of the first movable part 121 and the second movable part 122, and a second groove 126 is provided with a second cavity for accommodating the fixing bolt 131 of the pulley 130. The fixing bolt 131 is used to pass through the pulley 130 and the first movable part 121 and the pulley 130 and the second movable part 122 respectively, to fix the pulley 130 to the first movable part 121 and the second movable part 122 respectively.

[0052] In practical applications, the second groove 126 is used to accommodate the first crossbar 111, and a second cavity is also provided in the second groove 126 to accommodate the fixing bolt 131. To ensure that the fixing bolt 131 passes through the second cavity and does not interfere with the first crossbar 111, the dimension of the second cavity extending toward the first crossbar 111 does not exceed the dimension of the second groove 126 in the lateral direction. For details, please refer to the appendix. Figure 6 The fixing bolt 131 passes through the pulley 130 and the first movable part 121, and the part that extends out after the pulley 130 and the second movable part 122 is placed in the second groove cavity to avoid contact with the first crossbar 111, so that the detachable bracket 120 slides more smoothly on the fixed base 110.

[0053] Furthermore, in some preferred embodiments, the ends of the first movable part 121 and the second movable part 122 are respectively provided with hand-held push-pull parts 127, and the hand-held push-pull parts 127 are respectively arranged perpendicularly to the first movable part 121 and the second movable part 122 to form an inverted "L" shape.

[0054] In practical applications, in order to facilitate the pushing and pulling of the detachable hanger 120, hand-held push-pull parts 127 in the shape of inverted "L" can be provided at the ends of the first movable part 121 and the second movable part 122 respectively. In actual use, the detachable hanger 120 can be pushed in or pulled out by holding the hand-held push-pull part 127, which is very convenient to operate.

[0055] Furthermore, in some preferred embodiments, the bottom of the handheld push-pull part 127 is provided with a push-pull insertion hole 1271 for inserting a tool to push the first movable part 121 and / or the second movable part 122 into the fixed base 110, or pull them out from the fixed base 110.

[0056] In practical applications, since the detachable hanger pulley 100 is entirely set in the guide rail, it is inconvenient to directly grasp the hand-held push-pull part 127 to pull the detachable hanger 120 out of the fixed base 110 during actual operation. To solve this problem, a push-pull insertion hole 1271 can be provided at the bottom of the hand-held push-pull part 127. When in use, insert a screwdriver with a bent structure into the insertion hole, pull the detachable hanger 120 out of the guide rail range, and then grasp the hand-held push-pull part 127 to pull it out, thereby improving the convenience of assembling and disassembling the detachable hanger 120.

[0057] Furthermore, in some preferred embodiments, a third groove 128 is provided at one end of the first movable part 121 and the second movable part 122 near the hand-held push-pull part 127. After the first movable part 121 and the second movable part 122 are combined, the two third grooves 128 form a third cavity. A first through hole 116 is provided on the fixed base 110 corresponding to the third cavity. The first through hole 116 communicates with the third cavity and is used to install screws 119 to fix the fixed base 110 and the detachable bracket 120.

[0058] Please refer to Figure 6 In practical applications, in order to fix the detachable hanger 120, which is snapped onto the fixed base 110, to the fixed base 110 and make the connection structure between the two more stable, a third groove 128 can be provided at one end of the first movable part 121 and the second movable part 122 near the hand-held push-pull part 127. The hand-held push-pull part 127 is provided at one end facing the outside of the guide rail. The third groove 128 is set adjacent to the hand-held push-pull part 127. After the first movable part 121 and the second movable part 122 are combined, the third groove 128 forms a third cavity. A first through hole 116 is provided on the fixed base 110 corresponding to the third cavity. The first through hole 116 communicates with the third cavity and is used to set screws 119. This makes it convenient to use a bent screwdriver to unscrew the screws 119 during disassembly. It is not necessary to go deep into the guide rail to disassemble the fixing structures such as limit shafts and screws used for fixing. This makes the disassembly and assembly of the detachable hanger pulley 100 more convenient.

[0059] Furthermore, in some preferred embodiments, a second through hole 117 is provided in the middle of the fixed base 110 for mounting the screw 118.

[0060] In practical applications, please refer to Figure 1 , Figure 7The screw 118 is connected to the fixed base 110 and the guide rail through the second through hole 117 in the middle of the fixed base 110, which helps to save installation space.

[0061] Furthermore, in some preferred embodiments, the first movable part 121 and the second movable part 122 are respectively provided with a fourth groove 1201 recessed in the direction of the pulley 130. The outer surface of the fourth groove 1201 is arc-shaped and protrudes, and the distance of the protrusion is less than the distance between the pulley 130 and the first movable part 121 or the second movable part 122.

[0062] In practical applications, since the screw 118 is a cylinder and its volume is relatively large, sufficient space is required to house it. Therefore, a fourth groove 1201 can be provided on the first movable part 121 and the second movable part 122, respectively, recessed towards the pulley 130. The outer surface of the fourth groove 1201 is arc-shaped and convex to provide the space required by the screw 118. This method saves space compared to directly reserving a sufficiently wide gap inside the first movable part 121 and the second movable part 122 to accommodate the screw 118. Specifically, since the pulley 130 is also connected to the outer side of the first movable part 121 and the second movable part 122, directly placing the pulley 130 between the first movable part 121 and the second movable part 122 would not be feasible. Setting the distance between the first movable part 121 and the second movable part 122 is more spacious. After they are connected to the pulley 130, the horizontal dimension of the overall structure in cross-section will be larger, which may cause them to collide with the guide rail. To solve this problem, the fourth groove 1201 can be set only at the location of the screw 118. The distance of the arc-shaped protrusion on the surface of the fourth groove 1201 is less than the distance between the location of the pulley 130 and the first movable part 121 or the second movable part 122. This will reduce the overall volume of the detachable hanger 120 wheel and allow it to be better installed in the guide rail.

[0063] Furthermore, in some preferred embodiments, after the first movable part 121 and the second movable part 122 are combined, the two fourth grooves 1201 form a fourth cavity, and the fourth cavity communicates with the second through hole 117 for mounting the screw 118.

[0064] In practical applications, the first movable part 121 and the second movable part 122 are combined to form a fourth cavity. The fourth cavity is connected to the second through hole 117, which can be better used to set the screw 118 and avoid interference during the installation of the screw 118.

[0065] In practical applications, please refer to Figures 8 to 11The detachable hanging pulley 100 is located at one end of the guide rail, while the other end of the guide rail is symmetrically equipped with detachable wheel tails 200, which have a similar structure to the detachable hanging pulley 100. The detachable wheel tails 200 also have a first movable part 121 and a second movable part 122, as well as a fixed base 110.
