Description

Technical Field

[0001] This utility model relates to the field of bed frame accessories technology, specifically to an extension arm. Background Technology

[0002] As people's living standards improve, more and more people enjoy outdoor activities such as picnics and fishing. As a result, portable outdoor beds are becoming more and more diverse. Some portable outdoor beds can also be used to install tents to improve comfort during rest. Specifically, there are mounting holes at the four corners of the upper surface of the bed, and the tent feet can be inserted into the mounting holes.

[0003] However, due to the portability of outdoor portable beds, the space of the bed frame is not very large. Installing a tent directly on the bed frame will further reduce the space of the bed frame. Moreover, the mounting holes on the bed frame are often single and in fixed positions, which makes it impossible to adjust the installation of the tent feet according to actual needs, resulting in poor applicability. Therefore, there is a need for an extension arm that can be installed on the bed frame to install the tent feet and facilitate the adjustment of the feet. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an extendable arm to solve the issues in the prior art where installing a tent directly on the bed frame further compresses the bed space, and the tent feet have a limited range of installation positions that cannot be adjusted according to actual needs.

[0005] This utility model is achieved using the following technical solution: an extension arm, including a mounting plate, the mounting plate having a plurality of insertion holes for mounting tent feet, and a mounting post that is fixedly installed at one end of the mounting plate and inserted into the mounting hole.

[0006] The above structure ensures that the tent feet will not further compress the space of the bed during installation, and the installation positions of the tent feet are more diverse, increasing the applicability of this device.

[0007] Preferably, the plurality of the sockets are arranged in an array along the length of the mounting plate. This arrayed arrangement of the sockets allows for a more uniform distribution of force on the extension arm, further increasing the stability of the device.

[0008] Preferably, a laterally sliding limiting block is installed at the bottom of the mounting column, with one end of the limiting block extending to the outer side of the mounting column. The limiting block prevents the mounting column from detaching upwards from the bed frame after installation.

[0009] Preferably, the mounting column is further provided with an elastic reset mechanism for pushing the limiting block outwards from the mounting column. The elastic reset mechanism allows the limiting block to automatically pop out when it reaches below the bed, reducing manual intervention and making it more convenient to use.

[0010] Preferably, the bottom surface of the mounting column is provided with a downward-opening mounting groove, and an elastic plate is installed in the mounting groove. One end of the elastic plate abuts against the inner wall of the mounting groove, and the other end is fixedly connected to the limiting block. The elastic plate allows the limiting block to pop out when not under pressure.

[0011] Preferably, the elastic plate is inverted "V" shape. The "V" shaped elastic plate allows it to be more securely held in the mounting groove, making the structure of the device more stable.

[0012] Preferably, the elastic plate and the limiting block are integrally formed. By making the elastic plate and the limiting block integrally formed, it is possible to prevent the limiting block from popping out of the mounting post and to prevent the elastic plate from moving downward and falling out of the mounting groove.

[0013] Preferably, the mounting plate is further provided with a first limiting groove and a second limiting groove at the end near the mounting post. The first and second limiting grooves prevent the mounting plate from rotating after installation.

[0014] Preferably, the mounting plate and the mounting column are integrally formed. This integral forming of the mounting plate and mounting column makes the structure of the device more stable and further increases its service life.

[0015] Preferably, the mounting plate has reinforcing ribs located between two adjacent insertion holes. The addition of these reinforcing ribs further improves the stability of the device and increases its service life.

[0016] In summary, the beneficial effects of this utility model are as follows:

[0017] By using the mounting plate and mounting posts, the mounting posts are installed on the mounting holes in the bed frame. By selecting a suitable angle for installation, the installation area of ​​the bed frame can be expanded, avoiding the compression of bed space caused by installing a tent. In addition, the multiple holes on the mounting plate make the installation position of the tent feet more versatile. When installing the tent, the installation position of the tent feet can be adjusted according to one's own needs, making it more convenient to use and more applicable. Attached Figure Description

Detailed Implementation

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0027] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0028] like Figure 1 , Figure 2 As shown, this utility model provides an extension arm, including a mounting plate 1, on which a plurality of insertion holes 3 for mounting tent feet are provided; specifically, the insertion holes 3 are arranged in an array along the length direction of the mounting plate 1, and a reinforcing rib 14 is provided on the mounting plate 1 between two adjacent insertion holes 3. A mounting post 2 that can be inserted into the mounting hole 11 is fixedly installed at one end of the mounting plate 1 that mates with the bed frame 10.

[0029] like Figure 2 , Figure 3 , Figure 4As shown, to prevent the mounting post 2 inserted into the mounting hole 11 from moving upward, a laterally sliding limiting block 4 is installed at the bottom of the mounting post 2. The end of the limiting block 4 away from the mounting post 2 extends to the outside of the mounting post 2. A mounting sleeve 9 is fixedly installed at the corner of the bed frame 10. The mounting hole 11 passes through the bed frame and the mounting sleeve 9. When the mounting post 2 passes through the mounting hole 11, the limiting block 4 at the bottom of the mounting post 2 is below the mounting sleeve 9. At this time, the limiting block 4 is pulled out. When the mounting post 2 wants to move upward, the limiting block 4 can abut against the bottom of the mounting sleeve 9, thereby preventing the mounting post 2 from moving upward.

[0030] As a further illustration of this example, the mounting post 2 is also equipped with an elastic reset mechanism for pushing the limiting block 4 outward from the mounting post 2. With the elastic reset mechanism, after the mounting post 2 and the mounting sleeve 9 are inserted, the limiting block 4 no longer needs to be manually pulled out; instead, it pops out automatically, reducing manual intervention and making it more convenient to use.

[0031] The elastic reset mechanism in this device can be any mechanism that allows the limiting block 4 to pop out. For example, a sliding groove is provided on the side wall of the mounting post 2, and the limiting block 4 is slidably installed in the sliding groove. A reset spring is provided between the end of the limiting block 4 located inside the mounting post 2 and the inner wall of the sliding groove. In this embodiment, the elastic reset mechanism adopts the form of an elastic plate 5. Specifically, an opening-down mounting groove 6 is provided on the bottom surface of the mounting post 2, and an elastic plate 5 is installed in the mounting groove 6. One end of the elastic plate 5 abuts against the inner wall of the mounting groove 6, and the other end is fixedly connected to the limiting block 4.

[0032] As a further illustration of this example, the elastic plate 5 and the limiting block 4 are integrally formed. The limiting block 4 is installed by providing a through hole on the side wall of the mounting post 2 that communicates with the mounting groove 6, and the limiting block 4 slides in the through hole. By making the elastic plate 5 and the limiting block 4 integrally formed, it is possible to prevent the limiting block 4 from popping out of the mounting post 2 and to prevent the elastic plate 5 from moving downward and falling out of the mounting groove 6.

[0033] As a further illustration of this example, the elastic plate 5 is inverted "V" shape. This structure allows the elastic plate 5 to be more firmly engaged in the mounting groove 6, reducing the chance of the elastic plate 5 falling off.

[0034] As a further illustration of this example, the mounting plate 1 and mounting column 2 in this device are integrally molded. This integral molding design makes the structure of the device more stable and extends its service life. Furthermore, the integral molding design facilitates mass production using molds, resulting in better economic benefits.

[0035] like Figure 5 , Figure 6As shown, the mounting plate 1 is also provided with a first limiting groove 7 and a second limiting groove 8 at one end near the mounting column 2. By setting the first limiting groove 7 and the second limiting groove 8, and by cooperating with the first limiting column 12 and the second limiting column 13 on the bed body 10, it is ensured that the device will not rotate after installation.

[0036] The operating principle of this device is as follows: When the tent needs to be installed, first press the limiting block 4, then insert the mounting post 2 into the mounting hole 11 of the bed frame 10. After insertion, the limiting block 4 is popped out by the elastic plate 5, thus preventing the mounting post 2 from moving upward. During the insertion of the mounting post 2, the installation angle of the mounting plate 1 must also be selected. There are three states: State 1, the first limiting post 12 is located in the first limiting groove 7, and the second limiting post 13 is located in the second limiting groove 8; State 2, the second limiting post 13 is located in the first limiting groove 7; State 3, the first limiting post 12 is located in the second limiting groove 8. After the extension arms at all four corners of the bed frame 10 are installed, the tent feet can be inserted into the appropriate insertion holes to complete the tent installation.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
