Description

Technical Field

[0001] The present application relates to a bracket, and in particular to a multi-rod bracket that needs to be assembled. Background Art

[0002] In daily life, clothes, towels, medicinal materials, dried fruits, etc. often need to be dried from a wet state, and the drying process needs to be moved as the position of the sunlight changes to speed up the drying process. Therefore, in the prior art, various drying racks are provided, which can be installed by users themselves, and are relatively light and can be easily carried. For example, a clothes drying rack disclosed in Chinese patent ZL201920446142.9, such a drying rack is usually provided with two main rods, and a plurality of horizontal cross bars are provided between the two main rods to form a grid-like frame for supporting the items to be dried.

[0003] However, since this type of bracket is relatively large in size after being assembled, the main rod and the transverse rod are separated and packed during transportation, and then assembled by the user. The assembly process is generally to first plug all the transverse rods on one side of the main rod, and then plug the other main rod with the other side of the transverse rod. When there are many transverse rods, when plugging the unplugged transverse rods, the plugged transverse rods are easy to fall off from the main rod, which makes it difficult for the user to assemble. Figure 1 For example, the assembly process is generally to first plug one end of several transverse rods 3' into the second main rod 2', and then plug the first main rod 1' into the second ends of several transverse rods 3'. At this time, if the transverse rods at L, M, and N are plugged into the first main rod 1' first, when the transverse rods 3' at X, Y, and Z are plugged in, the first main rod 1' needs to be partially disengaged from the transverse rod 3', which can easily cause the assembled transverse rods at L, M, and N to be detached from the first main rod 1', resulting in installation failure.

[0004] Therefore, there is an urgent need for a bracket that can effectively reduce the situation where the assembled cross bars are separated from the first main bar when assembling subsequent cross bars, so that users can easily assemble. Utility Model Content

[0005] The present application aims to solve the problem of difficult bracket assembly in the prior art to a certain extent, and to provide a bracket with a simple structure and convenient assembly. To this end, the present application provides a bracket, comprising:

[0006] Two beam arms with plug connectors on the sides;

[0007] A cross bar, both ends of which are respectively plugged into the plug connectors on the two beam arms;

[0008] The beam arm also includes a load-bearing groove extending along the length direction of the cross bar. The load-bearing groove has an opening along the radial direction of the cross bar, and is arranged in sequence with the plug connector along the length direction of the cross bar, so that the end of the cross bar can enter the load-bearing groove from the opening and then be plugged into the plug connector, or when the end of the cross bar is released from the plug connector, the end of the cross bar is confined to the load-bearing groove.

[0009] In some embodiments, the plug connector is formed as a protrusion or a groove extending along the length direction of the cross bar on the side of the beam arm. When the plug connector is formed as a protrusion, the end of the cross bar is tubular, and the cross bar is connected to the plug connector by being sleeved on the outside of the plug connector; when the plug connector is formed as a groove, the cross bar is connected to the plug connector by being sleeved into the plug connector.

[0010] In some embodiments, a plurality of retaining ribs are circumferentially arranged on the plug connector. When the plug connector is formed into a protrusion, the retaining ribs protrude toward the outside of the plug connector, and the inner side of the tube wall at the end of the cross bar forms a tight fit with the retaining ribs, so that the cross bar and the plug connector are plugged together; when the plug connector is formed into a groove, the retaining ribs protrude toward the inside of the plug connector, and the outer side of the end of the cross bar forms a tight fit with the retaining ribs, so that the cross bar and the plug connector are plugged together.

[0011] In some embodiments, the clamping ribs include at least four and are evenly distributed along the circumference of the plug connector.

[0012] In some embodiments, the shape of the bearing groove is adapted to the shape of the end of the cross bar, so that the cross bar can enter the bearing groove, slide toward the plug connector, and be plugged into the plug connector.

[0013] In some embodiments, the size of the opening of the bearing groove does not exceed the radial size of the end of the cross bar, and the groove wall of the bearing groove has elastic deformation ability so that the end of the cross bar can enter the bearing groove.

[0014] In some embodiments, the end of the crossbar is cylindrical, and the size of the opening is smaller than the radial size of the end of the crossbar;

[0015] Or the end of the crossbar is in the shape of a polygonal column, and the size of the opening is equal to the minimum radial size of the end of the crossbar.

[0016] In some embodiments, along the length direction of the crossbar, the length of the bearing groove is 10-25 mm.

[0017] In some embodiments, each of the beam arms includes two rotatably connected short arms, and the rotatable connections of the two beam arms are coaxial. A locking button is provided at the rotatable connection of the two short arms, and the locking button is used to lock the two short arms so that the two short arms have an unlocked state in which they can rotate relative to each other and a locked state in which they cannot rotate relative to each other.

[0018] In some embodiments, along the length direction of the short arm, each short arm is detachably connected to a foot at one end away from the rotating connection; along the side of the short arm, the short arm also includes a connecting head, and when the foot is removed from the end of the short arm away from the rotating connection, it can be detachably connected to the connecting head.

[0019] The bracket of the present application is provided with a bearing groove on the beam arm, and the bearing groove and the plug connector are arranged along the length direction of the cross bar, and an opening is provided on the bearing groove. When the cross bar needs to be assembled, the end of the cross bar can be first entered into the bearing groove through the opening. After all the cross bars and the bearing groove are assembled, the beam arm is pressed toward the cross bar, and all the cross bars and the plug connector can be connected; or a part of the cross bars can be plugged into the plug connector first, and when the subsequent cross bars and the plug connector continue to be plugged into, the already plugged cross bars will fall into the bearing groove even if the plug-in with the plug connector is released, thereby avoiding the cross bars from falling. The use of the bearing groove greatly reduces the assembly difficulty of the user, and can also adapt to various assembly methods and improve the user experience. At the same time, the bracket of the present application only adds a bearing groove on the beam arm, which avoids the overall structure from changing much compared with the bracket in the prior art. Therefore, the overall cost is low and the production and processing are convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0041] Example 1:

[0042] like Figure 2 、 3 As shown, the present application discloses a bracket, which is supported by two beam arms 1. A plug connector 11 is provided on the side of each beam arm 1 for plugging into the end of a cross bar 2 to fix the cross bar 2 between the two beam arms 1, so that the bracket forms a grid shape in which several cross bars 2 are arranged between the two beam arms 1 along the length direction of the beam arms 1. Therefore, users can place items to be dried on the cross bars 2 for drying. Of course, this bracket can also be used as a storage rack in cabinets, desk cabinets, shoe racks, etc.

[0043] In the scheme of this embodiment, the plug-in means that the cross bar 2 can be moved toward the plug connector 11 along a fixed direction (generally the length direction of the cross bar 2), and a fit is formed by the mutual fitting and interlocking of the two, such as the fit of the pin and the hole, the fit of the elastic claw and the block, etc. Taking the fit of the pin and the hole as an example, the characteristic of this fit is that when the pin moves into the hole, the inner wall of the hole can fit with the outer wall of the pin, so that the two remain in a relatively fixed state, but under the action of external force, the pin can move in the opposite direction to get out of the hole, so that the fit is released.

[0044] In the solution of this embodiment, a load-bearing groove 12 is further provided on the beam arm 1, and the load-bearing groove 12 extends along the length direction of the cross bar 2, so that the cross bar 2 can slide in the load-bearing groove 12; and the load-bearing groove 12 has an opening 121 along the radial direction of the cross bar 2, so that the end of the cross bar 2 can enter the load-bearing groove 12 from the opening 121, and at the same time, the load-bearing groove 12 and the plug connector 11 are arranged on one side along the length direction of the cross bar 2, that is, viewed from the side of the beam arm 1, the plug connector 11 is closer to the beam arm 1 than the load-bearing groove 12, that is, the load-bearing groove 12 is located on the outside of the plug connector 11, and it can be connected to the end of the plug connector 11, or it can be connected to the side of the beam arm 1 and extend to the outside of the plug connector 11 so that the two are arranged in sequence along the length direction of the cross bar 2.

[0045] When the cross bar 2 needs to be installed, the user can plug the first end of the cross bar 2 into the plug connector 11 on one beam arm 1, and then place the second end of the cross bar 2 into the bearing groove 12 of the other beam arm 1 through the opening 121 on the bearing groove 12, until all the cross bars 2 are installed in this way, and then move the other beam arm 1 and the cross bar 2 relative to each other along the length direction of the cross bar 2, so that the second ends of all the cross bars 2 are simultaneously matched with the plug connector 11 on the other beam arm 1. Alternatively, the user can first plug and mate the first ends of all the cross bars 2 with the plug connector 11 on one beam arm 1, and then plug and mate the second ends of the cross bars 2 with the plug connector 11 on another beam arm 1 in turn. At this time, even if the cross bar 2 that has been plugged and matched first comes out of the plug connector 11, it will fall into the load-bearing groove 12 and will not be directly separated from the beam arm 1. The user only needs to push the beam arm 1 toward the cross bar 2 to plug and mate the plug connector 11 with the cross bar 2 again, so that the assembled cross bar 2 will not be completely separated from the beam arm 1 in the prior art, and the user will not need to align the cross bar 2 with the plug connector 11 one by one again. This makes it more convenient for the user to assemble the bracket, and it can be easily completed by one person.

[0046] In some embodiments, the plug connector 11 is formed as a protrusion on the side of the beam arm 1, which extends along the length of the crossbar 2. The end of the crossbar 2 is a tubular body that can be mounted on the plug connector 11. In actual products, the crossbar 2 is entirely tubular, so that the weight of the crossbar 2 can be kept very small, thereby reducing the weight of the entire bracket. The cross section of this tubular body can be circular, polygonal, etc., and the more common ones are round tubes and square tubes, for example Figure 2The crossbar 2 in the figure is a round tube. It should be understood that the outer shape of the plug connector 11 should be adapted to the inner wall of the tubular body at the end of the crossbar 2, that is, when the end of the crossbar 2 is sleeved on the outside of the plug connector 11, the outer wall of the plug connector 11 does not exceed the radial range of the crossbar 2. It is best that the outer diameter of the plug connector 11 is slightly larger than or equal to the inner diameter of the tubular body of the crossbar 2, so that when the two are plugged in, a relatively small degree of tight fit is formed to prevent the crossbar 2 from easily falling out of the plug connector 11. For example, when the end of the crossbar 2 is a round tube, the outer shape of the plug connector 11 can be a round tube with the same inner diameter as the end of the crossbar 2, or it can be a polygonal or irregular shape inscribed in the round tube at the end of the crossbar 2, as long as at least a portion of the outer wall of the plug connector 11 is in tight contact with the inner wall of the crossbar 2 when the two are plugged in.

[0047] Specifically, in some embodiments, the plug connector 11 is formed as a protrusion on the side of the beam arm 1, and a plurality of retaining ribs 111 are provided on the outside thereof, which protrude toward the outside of the side of the plug connector 11. When the end of the crossbar 2 is plugged into the plug connector 11, the inner wall of the tubular body just presses the retaining ribs 111, so that the crossbar 2 and the plug connector 11 form a certain tight fit. Figure 5 As shown, for example, when the plug connector 11 is formed into a cylindrical protrusion, four clamping ribs 111 are provided and evenly distributed on the side circumference of the plug connector 11. When the cross bar 2 is plugged into the plug connector 11, the four clamping ribs 111 evenly abut against four symmetrical points on the inner wall of the plug connector 11, thereby avoiding the problem of poor plugging effect caused by the cross bar 2 and the plug connector 11 being offset to one side when the clamping ribs 11 are unevenly distributed.

[0048] Obviously, in the above method, the number of the clamping ribs 111 is not limited to Figure 5 The four shown in the figure can also be three, five, six or more, but the clamping ribs 111 should be evenly distributed along the outer circumference of the plug connector 11 to achieve a stable plugging effect.

[0049] In this embodiment, if Figure 3-5 As shown, the cross bar 2 is generally a rod body of uniform shape, so the bearing groove 12 extends along the length direction of the cross bar 2, and its cross-sectional shape is consistent with the cross-sectional shape of the cross bar 2, so that the cross bar 2 can slide smoothly in the bearing groove 12, thereby being plugged into and matched with the plug connector 11, or the cross-sectional shape of the bearing groove 12 should at least satisfy the requirement that the end of the cross bar 2 can slide effortlessly along the length direction of the bearing groove 12 when entering the bearing groove 12, so that the end of the cross bar 2 can be smoothly plugged into and matched with the plug connector 11, for example, the maximum dimension of the cross section of the cross bar 2 is smaller than the dimension of the cross section of the bearing groove 12, or the cross section of the cross bar 2 is exactly the inscribed shape of the cross section of the bearing groove 12.

[0050] Furthermore, in some embodiments, Figure 5As shown, the size of the opening 121 does not exceed the radial size of the end of the crossbar 2, that is, the size of the opening 121 is less than or equal to the radial size of the end of the crossbar 2, that is, the load-bearing groove 12 forms a shape that is smaller than the internal space at the opening 121. At the same time, the groove wall of the load-bearing groove 12 has elastic deformation ability. For example, the load-bearing groove 12 is thin-walled and made of plastic, aluminum alloy or other materials. The thin walls of such materials can generally be slightly deformed, so that the end of the crossbar 2 can smoothly enter the load-bearing groove 12 from the opening 121. At the same time, when the size of the opening 121 is smaller than the radial size of the end of the crossbar 2, the crossbar 2 needs to be forced to enter or escape from the load-bearing groove 12 from the opening 121. Therefore, the crossbar 2 can enter the load-bearing groove 12 from the opening 121, thereby achieving the effect of convenient installation of multiple crossbars 2 and the plug connector 11, and preventing the crossbar 2 from arbitrarily escaping from the load-bearing groove 12, causing the assembled crossbar 2 to be separated from the beam arm 1 and requiring reinstallation.

[0051] Specifically, if Figure 3 、 5 As shown, the end of the cross bar 2 is cylindrical, and the size of the opening 121 is smaller than the radial size of the end of the cross bar 2, that is, smaller than the circular diameter of the cross section of the end of the cross bar 2. When the cross bar 2 needs to be installed into the load-bearing groove 12, the side surface of the end of the cross bar 2 can be gradually used to support the groove wall of the load-bearing groove 12 at the opening 121 to cause it to deform. The size of the opening 121 also gradually increases so that the cross bar 2 can smoothly enter the load-bearing groove 12. When the cross bar 2 is completely entered into the load-bearing groove 12, the groove wall at the opening 121 can use its own elasticity to restore the deformation. When there is no external force, the cross bar 2 can only slide along the load-bearing groove 12 and cannot directly fall out of the opening 121. This avoids the cross bar 2 from falling out of the opening 121 when it is not plugged into the plug-in portion 11 during installation, causing the installation to fail.

[0052] In a household environment, the size of the bracket 1 is generally such that the distance between the two beam arms 1 is less than 100mm, that is, the specifications of the cross bar 2 are usually 500mm, 600mm, 800mm, 1000mm and the like. However, the longer the cross bar 2, the greater the range of error generated during assembly, that is, the easier it is to come off from the plug connector 11. Therefore, the length of the bearing groove 12 cannot be too small to produce a better limiting effect on the cross bar 2. For industrial products, when the cross bar 2 is a uniform rod body, the bearing groove 12 will protrude from the side of the cross bar 2 at the end of the cross bar 2 on the assembled bracket, which affects the aesthetics of the product. At the same time, when drying towels, clothes and other items, , an excessively long load-bearing groove 12 may shorten the length of the crossbar 2 that can be effectively utilized. Therefore, the length of the load-bearing groove 12 cannot be too long. Based on this, after fully considering the bracket size and crossbar size in existing products and investigating the influence of load-bearing grooves 12 of different lengths on the user's tendency to choose the corresponding product, the inventor found that the most suitable size of the load-bearing groove 12 should be between 10-25mm, with 17mm being the best. When it is smaller than this size range, the limiting effect of the load-bearing groove 12 on the crossbar 2 is significantly weakened. When it is larger than this size range, the load-bearing groove 12 affects the effective utilization length of the crossbar 2 of most existing brackets, and the aesthetics deteriorates, and the user's tendency to choose is weakened. It should be noted that in the above description, the length of the load-bearing groove 12 refers to the length of the load-bearing groove 12 extending from the end of the plug connector 11 away from the beam arm 1, that is, from the end of the plug connector away from the beam arm 1 to the end of the load-bearing groove 12 away from the beam arm 1.

[0053] In some embodiments, as Figure 4 Each beam arm 1 is composed of two short arms 13, the ends of the two short arms 13 are rotatably connected and locked using a locking button 14. When the two short arms 13 need to be rotated, the locking button 14 is opened, and the user rotates the two short arms 13 to the desired angle, and then uses the locking button 14 to lock the two short arms 13. This locking method is common in the existing technology and will not be described in detail here. However, it should be noted that when both beam arms 1 are composed of two short arms 13, after the bracket is installed, the rotation of the two beam arms 1 should be coaxial, so that the entire bracket is formed into two parts that can rotate relative to each other.

[0054] The end of each short arm 13 away from the rotation center exceeds a portion of the cross bar 2, that is, the cross bar 2 will not be installed to the end of the short arm 13. When the user needs to support the bracket in an "A" shape, such as Figure 1 In the middle state, one end of the four short arms 13 away from the rotation center can be supported on the ground, a desktop, etc., and the user can place the items to be dried on the bracket.

[0055] In some embodiments, as Figure 4 、 6As shown, each short arm 13 has a detachable support leg 131 at one end away from the rotating connection. The support leg 131 is set at a position on the short arm 13 where the cross bar 2 does not need to be installed, that is, the length of the short arm 13 can be extended by the support leg 131, and then the extent of the beam arm 1 can be extended, so that the bracket can adapt to different space requirements. For example, in a longer table space, the support leg 131 can be installed so that the bracket can be placed in a longer space. Correspondingly, the overall volume of the bracket can be reduced by removing the support leg 131 to adapt to a smaller space.

[0056] Furthermore, a connector 132 can be provided on the side of the short arm 13 for detachable connection with the support leg 131. This design is to prevent the beam arm 1 from directly contacting the ground when the bracket needs to be laid flat. Since a general bracket is formed into a flat mesh after assembly, each connector 132 faces one side of the bracket. When the four short arms 13 are connected to the support leg 131 through the connector 132 on the side, all the support legs 131 face one side of the bracket to form four legs supporting the bracket. In turn, the bracket can contact the ground through the support legs 131, so that the crossbar 2 has a certain distance from the ground, preventing the objects being dried from directly contacting the ground.

[0057] In the above embodiment, the support leg 131 is detachably connected to the end of the short arm 13 and the connector 132. Therefore, in order to facilitate processing and manufacturing, the structure of the end of the short arm 13 and the connector 132 should be the same, for example, Figure 4 、 6 In the above-mentioned manner, the end of the short arm 13 and the connecting head 132 can be inserted into the support leg 131, and the support leg 131 can be connected to the end of the short arm 13 and the connecting head 132 respectively by means of a sleeve connection. Obviously, the end of the short arm 13 and the connecting head 132 can also be set as a tubular body, and the support leg 131 can be inserted into the inside of the tubular body to be detachably connected to the end of the short arm 13 and the connecting head 132 respectively. The above-mentioned sleeve connection method does not require additional devices for installation, can save costs to the greatest extent, and is convenient for users to operate.

[0058] Example 2:

[0059] The difference from the above embodiment is that Figure 7-10As shown, the plug connector 11 is formed as a groove on the side of the beam arm 1, that is, the cross bar 2 can be plugged into the beam arm 1 by inserting it into the groove body of the plug connector 11. This method is suitable for some cross bars 2 that are not convenient to be processed into a tubular shape. For example, when the material of the cross bar 2 is relatively brittle, once the plug connector 11 of the first embodiment is adopted, when the cross bar 2 is inserted into the plug connector 11, the end of the cross bar 2 may be directly broken due to the tight fit with the plug connector 11, causing product damage, or when the tube wall of the tubular end of the cross bar 2 is relatively thin, the tube wall of materials such as aluminum is easily squeezed and deformed by the plug connector 11 of the first embodiment, resulting in unstable connection. Therefore, the plug connector 11 is set to a groove form, and the end of the cross bar 2 is inserted into the plug connector 11 so that the two are plugged together, which can make the plugging of the two stable and avoid damage to the cross bar 2. Especially when the cross bar 2 is a solid rod body, the effect is more obvious.

[0060] Further, in some embodiments, as Figure 10 As shown, a retaining rib 111 is provided on the inner wall of the groove-shaped plug connector 11. When the end of the baffle cross bar 2 is inserted into the plug connector 11, the retaining rib 111 is tightly fitted with the outer side surface of the end of the cross bar 2. The effect is the same as that of the retaining rib 111 in Example 1, which will not be repeated here.

[0061] Furthermore, in some embodiments, the end of the crossbar 2 is a polygonal cylinder, such as Figure 11 The cross bar 2 is a quadrilateral column, so the bearing groove 12 is also formed into a square groove adapted to the quadrilateral column. At this time, in order to enable the cross bar 2 to be placed into the bearing groove 12 from the opening 121, the size of the opening 121 should be at least larger than the width of one face of the quadrilateral column. This polygonal column method can prevent the cross bar 2 and the beam arm 1 from rotating relative to each other after assembly. For some environments where a fixed bracket is required, the polygonal column cross bar 2 is more stable than the cylindrical cross bar 2.
