[0002] A camping tent is a shelter erected on the ground to provide protection from wind, rain, and sunlight, and to offer temporary living space. A tent consists of a frame made of many support poles and supported by a canvas.

[0040] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0041] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0044] One aspect of this application provides a tent extension system, such as Figures 1 to 4As shown, one preferred embodiment includes a tent, extension poles 71, and extension components (not shown). The tent includes a tent body, support poles 72, and a tent head at the top; the tent body is generally made of waterproof fabric, and the support poles 72 are generally hollow cylindrical structures. During tent setup, multiple support poles 72 pass through connection points on the tent body to form a support frame that tensions the tent body. The lower ends of the multiple support poles 72 are generally inserted into the ground, and the upper ends of the multiple support poles 72 can be connected to the first connecting sleeve 2 on the tent head, making the support frame structure formed by the multiple support poles 72 stable. The extension poles 71 are connected to the second connecting sleeve 3 on the tent head and extend horizontally to form an extension frame, with extension components laid on the extension poles 71.
[0045] It should be noted that, in order to meet the needs of multiple scenarios, tents can be expanded in different ways in different scenarios. For example, they can be extended outwards at the entrance to form a rain shelter, that is, the extension component is the rain shelter fabric that forms the rain shelter; or multiple tents can be connected and expanded in sequence to increase the applicable space of the tent, that is, the extension component is the connecting fabric that connects two tents.
[0046] For expanding the rain shelter, it can be tensioned by pulling ropes, or an additional frame can be erected on the ground for installation. The rope tensioning method requires more space and has generally lower stability; the additional frame method, because it is independent of the tent's support frame, has poor stability and is inconvenient to set up.
[0047] For connecting and expanding multiple tents, the traditional method is to connect a connecting fabric between the two adjacent tents using a zipper. Since the zipper needs to span both sides of the connecting fabric and the connecting fabric is installed at a high position, the tents need to be disassembled before the connecting fabric can be installed. This inevitably makes the entire setup process cumbersome and time-consuming.
[0048] In the technical solution of this application, such as Figure 2 and Figure 4 As shown, an extension rod 71 is used for tent structural expansion. The extension rod 71 connects to the tent head for setting up the tent, ensuring a structural connection between the expansion frame formed by the extension rod 71 and the tent's support frame, thus guaranteeing the stability of the tent's expanded structure. After connecting the extension rods 71 to form the expansion frame, simply lay the expansion components onto the frame, effectively reducing the difficulty and complexity of tent expansion. For ease of understanding, the specific expansion process for different expansion needs will be described in detail below.
[0049] In this embodiment, as Figure 1As shown, to meet the expansion needs of the tent's rain shelter, the extension component is installed at the tent's entrance / exit position; that is, the extension component is a rainproof cloth. One end of the extension rod 71 is connected to the second connecting sleeve 3 installed on the tent head, and the other end is connected to the support frame erected on the ground, so that the extension rod 71 is in a horizontal state. Then, the rainproof cloth is laid on the extension rod 71, so that the rainproof cloth forms an inverted "V" shaped rain shelter structure through the extension rod 71.
[0050] It is important to know that there are various specific structural types of support frames. For ease of understanding, a specific example is given below: the support frame can use two cross-connected support rods, with the lower ends of the support rods inserted into the ground. The end of the extension rod 71 away from the tent head is placed at the intersection of the two support rods. The intersection of the two support rods is at the same height as the installation position of the tent head to ensure that the extension rod 71 is in a horizontal state.
[0051] In this embodiment, as Figures 2 to 4 As shown, to address the connection and expansion needs of multiple tents, an extension component is installed between two tents; that is, the extension component is a connecting fabric. Both ends of the extension rod 71 are connected to the second connecting sleeves 3 installed on the tent heads at the top of the two tents, so that the extension rod 71 is horizontal between the two tents. Then, the connecting fabric is laid on the extension rod 71, so that the connecting fabric forms an inverted "V" shaped connection channel through the extension rod 71.
[0052] It should be noted that, in order to ensure the structural stability of the connecting channel, after the connecting cloth is laid in the middle of the extension rod 71, the two ends of the connecting cloth on the ground can be fixed to the ground with tent nails to keep the entire connecting cloth in a taut state.
[0053] Another aspect of this application provides a tent head for the aforementioned tent extension system, such as... Figure 5 As shown, one preferred embodiment includes a disc body 1, multiple first connecting sleeves 2, and a second connecting sleeve 3. The disc body 1 can be circular or a regular polygon, etc., and can be determined according to the actual needs of those skilled in the art. The first connecting sleeves 2 are used to connect to the support poles 72 of the tent, and multiple first connecting sleeves 2 are installed at intervals along the circumferential direction on the side of the disc body 1. The second connecting sleeves 3 are used to connect to the extension poles 71 of the extended tent. The second connecting sleeves 3 are rotatably installed on the disc body 1. When connecting the extension poles 71 and the second connecting sleeves 3, the angle of the port connecting the second connecting sleeves 3 to the extension poles 71 can be adjusted by rotating the second connecting sleeves 3 up and down around the installation position, so that the user can smoothly and quickly complete the connection of the extension poles 71 and the second connecting sleeves 3 without lifting the extension poles 71.
[0054] It is understood that the first connecting sleeve 2 is rotatably installed in the second mounting groove 102 provided on the side of the disc body 1, and the first connecting sleeve 2 can rotate vertically up and down around the second mounting groove 102, thereby ensuring that the inclined support rod 72 can be stably inserted into the first connecting sleeve 2. Furthermore, by adjusting the rotation of the first connecting sleeve 2, it can accommodate the installation of support rods 72 at different inclination angles.
[0055] It is also understandable that, since the extension rod 71 ultimately needs to be horizontal, if the second connecting sleeve 3 is directly set to a horizontal state, then during tent expansion, since the tent has already been set up and the tent head is at a relatively high height, the user may need to lift the extension rod 71 horizontally and insert it into the second connecting sleeve 3 of the tent head for fixation. This would make the installation process of the extension rod 71 more difficult. Therefore, in the technical solution of this application, the second connecting sleeve 3 is set to be rotatable, that is, the second connecting sleeve 3 can be in a downward-facing position. In this case, the user only needs to lift the extension rod 71 and insert one end into the second connecting sleeve 3 for connection.
[0056] It should be noted that the circumferential direction of disk 1 is a ring-shaped direction with the geometric center of disk 1 as the center; if disk 1 adopts a circular structure, then the geometric center is the center of the circle; if disk 1 adopts a regular polygonal structure, then the geometric center of disk 1 is the center of the circumcircle or incircle of the disk 1's outline. For ease of understanding, this embodiment uses a circular structure for disk 1 as an example.
[0057] It should be understood that the number of support poles 71 used for erection varies depending on the type of tent structure being built, with common numbers including three and four. Furthermore, as mentioned earlier, the expansion requirements of the tent also differ, so the specific number of second connecting sleeves 3 can be one or more depending on these different expansion requirements. For ease of understanding, several embodiments will be described in detail below.
[0058] Example 1: like Figure 5 As shown, there are three first connecting sleeves 2, and three second mounting slots 102 are equally spaced along the circumferential direction on the side of the disc body 1. There is one second connecting sleeve 3, and the side of the disc body 1 has a radially extending first mounting slot 101. The second connecting sleeve 3 is rotatably mounted in the first mounting slot 101. The second connecting sleeve 3 and the disc body 1 are engaged by a limiting structure, which limits the lower limit of the rotation angle of the second connecting sleeve 3.
[0059] It should be understood that whether it is the expansion of the tent's rain shelter or the connection and expansion of multiple tents, the expansion area is located at the tent's entrance and exit. Since the tent's entrance and exit are located in the tent body area between the two support poles 71, the first mounting slot 101 for installing the second connecting sleeve 3 is located between two adjacent second mounting slots 102.
[0060] Understandably, since the extension rod 71 is ultimately used horizontally, the upper limit of the rotation angle of the second connecting sleeve 3 is horizontal, meaning that the extension direction of the second connecting sleeve 3 at its upper limit of rotation is parallel to the radial direction of the disc body 1. The upper limit of the rotation of the second connecting sleeve 3 can be limited by the disc body 1, or the disc body 1 can not restrict the upward rotation of the second connecting sleeve 3, meaning the upward rotation of the second connecting sleeve 3 can exceed the radial direction of the disc body 1. Since the tent head is installed on the top of the tent, if the lower limit of the rotation angle of the second connecting sleeve 3 is too low, for example, if the second connecting sleeve 3 is in a vertically downward position, the end of the second connecting sleeve 3 will be directly facing the tent body. This may cause inconvenience when inserting the excessively long extension rod 71 into the second connecting sleeve 3. Therefore, the lower limit of the rotation angle of the second connecting sleeve 3 in its initial natural state needs to be at a suitable angle. Thus, by setting up a limiting structure, the lower limit of the rotation angle of the second connecting sleeve 3 can be limited, thereby ensuring that the extension rod 71 can be smoothly inserted into the second connecting sleeve 3.
[0061] In this embodiment, for the shorter extension rod 71, the angle between the extension direction of the second connecting sleeve 3 and the radial direction of the disk body 1 at the lower limit of rotation is less than or equal to 90°; for the longer extension rod 71, the angle between the extension direction of the second connecting sleeve 3 and the radial direction of the disk body 1 at the lower limit of rotation is less than 90°. The specific value of the lower limit of the rotation angle of the second connecting sleeve 3 can be selected according to the actual needs of those skilled in the art; for example... Figure 8 As shown, the angle between the extension direction of the second connecting sleeve 3 at the lower limit of rotation and the radial direction of the disk body 1 can be 30°, 45°, 60°, etc.
[0062] In this embodiment, the outer end of the second connecting sleeve 3 is flush with or located outside the opening of the first mounting groove 101. The second connecting sleeve 3 is connected to the extension rod 71 through its outer end. The inner end of the second connecting sleeve 3 located in the first mounting groove 101 can abut against the inner wall of the first mounting groove 101 through its lower outer peripheral surface to form a limiting structure.
[0063] Those skilled in the art should know that the second connecting sleeve 3 can abut against the inner wall of the first mounting groove 101 in various ways, including point-to-point contact, point-to-line contact, line-to-line contact, and surface-to-surface contact. Considering that the second connecting sleeve 3 always abuts against the inner wall of the first mounting groove 101 in its natural state, and that the second connecting sleeve 3 moves to contact the inner wall of the first mounting groove 101 under the action of gravity, this may cause impact when the second connecting sleeve 3 contacts the inner wall of the first mounting groove 101. If the contact between the second connecting sleeve 3 and the inner wall of the first mounting groove 101 is a point or line contact, over time this will cause accelerated wear at the contact point; therefore, in this embodiment, the contact between the second connecting sleeve 3 and the inner wall of the first mounting groove 101 is preferably a surface contact. For ease of understanding, a detailed description will follow.
[0064] In this embodiment, as Figure 6 and Figure 8 As shown, a limiting part 301 is provided on the lower outer circumferential surface of the inner end of the second connecting sleeve 3, and a limiting surface 401 is provided on the inner wall of the first mounting groove 101 located below the second connecting sleeve 3. When the second connecting sleeve 3 rotates to the point where the limiting part 301 contacts the limiting surface 401, the limiting part 301 and the limiting surface 401 come into contact and abut against each other to form a limiting structure.
[0065] It should be noted that there are multiple specific structural forms for the limiting part 301 on the lower side of the inner end of the second connecting sleeve 3 and the limiting surface 401 on the inner wall of the first mounting groove 101. For ease of understanding, two specific structures will be described in detail below.
[0066] Structure 1: such as Figure 6 and Figure 8 As shown. The inner end cross-section of the second connecting sleeve 3 is rectangular, so that a limiting part 301 is formed on the lower side of the inner end of the second connecting sleeve 3, and the limiting surface 401 is disposed on the inner wall of the port of the first mounting groove 101. When the second connecting sleeve 3 rotates to the lower limit of the angle, the limiting part 301 and the limiting surface 401 can be planarly fitted and abutted to form a limiting structure.
[0067] Structure 2: The second connecting sleeve 3 is cylindrical in shape, and an arc-shaped limiting part 301 can be formed on the lower outer circumferential surface of the inner end of the second connecting sleeve 3; the limiting surface 401 is disposed on the inner wall of the port of the first mounting groove 101, and the limiting surface 401 is also arc-shaped. When the second connecting sleeve 3 rotates to the lower limit of the angle, the limiting part 301 and the limiting surface 401 can be arc-shaped to fit and abut against each other to form a limiting structure.
[0068] It should be noted that the first mounting groove 101 can be integrally formed on the disc body 1 or it can be separately formed on the disc body 1. For ease of understanding, the specific formation method of the first mounting groove 101 will be described in detail below.
[0069] For the integrally formed first mounting groove 101, a through hole can be provided on the second connecting sleeve 3, and a corresponding through hole can also be provided on the first mounting groove 101; then, by aligning the through hole of the second connecting sleeve 3 with the through hole of the first mounting groove 101, the rotating shaft 302 can be inserted into the aligned through hole to complete the rotational installation of the second connecting sleeve 3. For the separately formed first mounting groove 101, such as Figures 6 to 8 As shown, a mounting port 103 is provided at a corresponding position on the disc body 1, and a base plate 4 is detachably mounted on the lower part of the disc body 1; the base plate 4 and the disc body 1 cooperate to form a first mounting groove 101, and a limiting surface 401 is provided on the base plate 4. A rotating shaft 302 is provided on both sides of the inner end of the second connecting sleeve 3; a first half-groove 104 is provided on the mounting port 103, and a second half-groove 402 is provided on the base plate 4; when the base plate 4 is installed on the disc body 1, the first half-groove 104 and the second half-groove 402 can cooperate to form a rotating groove for mounting the rotating shaft 302. Therefore, when installing the base plate 4, the rotating shaft 302 of the second connecting sleeve 3 can be placed into the first half-groove 104 first, and then the base plate 4 is connected to the disc body 1 so that the second half-groove 402 also cooperates with the rotating shaft 302.
[0070] It is important to understand that the connection between the second connecting sleeve 3 and the extension rod 71 can traditionally be achieved through a plug-in or threaded connection. For the plug-in method, considering the relatively weak structural rigidity of the tent itself, interference fits or transition fits are not suitable; only gap fits are possible, resulting in poor connection strength between the extension rod 71 and the second connecting sleeve 3. For the threaded connection method, the extension rod 71 may require multiple rotations to achieve the connection, and in scenarios involving multiple tents, it is not feasible to ensure that both ends of the extension rod 71 are threadedly engaged with the second connecting sleeve 3. Therefore, in this embodiment, a magnetic adsorption connection, different from traditional methods, is used to connect the second connecting sleeve 3 and the extension rod 71.
[0071] It is understandable that if the extension rod 71 is made of a magnetically adsorbable metal material, then only a magnetic attraction part needs to be provided on the second connecting sleeve 3. If the extension rod 71 is made of a non-magnetically adsorbable material, then magnetic attraction parts need to be provided on both the extension rod 71 and the second connecting sleeve 3; for example, a magnetically adsorbable metal block can be provided on the extension rod 71, and a magnetic block 5 can be provided on the second connecting sleeve 3, or both the extension rod 71 and the second connecting sleeve 3 can be provided with magnetic blocks 5. For ease of understanding, the following detailed description will be based on the example of the extension rod 71 being magnetically adsorbable and the second connecting sleeve 3 being provided with magnetic blocks 5.
[0072] In this embodiment, the magnetic block 5 can be installed on the side wall of the connecting cavity 300 of the second connecting sleeve 3 or at the bottom of the connecting cavity 300 of the second connecting sleeve 3. Considering the installation of the magnetic block 5, in this embodiment, it is preferable to install the magnetic block 5 at the bottom of the connecting cavity 300 of the second connecting sleeve 3.
[0073] Specifically, such as Figure 9 As shown, the bottom of the connecting cavity 300 of the second connecting sleeve 3 has a through mounting hole 303 along the axial direction. A fixing sleeve 501 is provided on the side of the magnetic block 5 away from the port of the connecting cavity 300. The fixing sleeve 501 extends into the mounting hole 303 and is fixedly connected. There are several ways to fix the fixing sleeve 501 to the second connecting sleeve 3. It can be an interference fit between the fixing sleeve 501 and the mounting hole 303, an adhesive fit, or a fastener fit. For ease of understanding, taking the fastener fit as an example, the fixing sleeve 501 has a threaded hole at its center. A screw 502 is screwed into the threaded hole of the fixing sleeve 501 at the outer side of the inner end of the second connecting sleeve 3 until the screw 502 is tightly fastened to the outer side of the inner end of the second connecting sleeve 3. It should be noted that to improve the connection stability of the screw 502, a washer can be fitted onto the screw 502 for tightening.
[0074] In this embodiment, to ensure the stable connection of the extension rod 71, although a clearance fit is used between the extension rod 71 and the connecting cavity 300 of the second connecting sleeve 3, the clearance between them should not be too large, otherwise the extension rod 71 may wobble during use. However, too small a clearance also makes it inconvenient to insert the extension rod 71 into the connecting cavity 300 of the second connecting sleeve 3. Therefore, if... Figure 6 and Figure 8 As shown, the outer end of the second connecting sleeve 3 is set in a trumpet shape so that the cross-sectional size of the port of the connecting cavity 300 of the second connecting sleeve 3 is larger than the cross-sectional size of the extension rod 71, thereby making it convenient for the extension rod 71 to be accurately inserted into the connecting cavity 300 of the second connecting sleeve 3.
[0075] Example 2: Compared to Embodiment 1, the difference in this embodiment is as follows: Figure 10 As shown, four second mounting slots 102 are provided on the side of the disc body 1 along the circumferential direction, and four first connecting sleeves 2 are also provided accordingly. A first mounting slot 101 is provided on the side of the disc body 1 between one pair of adjacent second mounting slots 102, and one second connecting sleeve 3 is provided, which is rotatably mounted in the position of the first mounting slot 101.
[0076] Example 3: Compared with Embodiment 1 and Embodiment 2, the difference in this embodiment is as follows: Figure 11 As shown, four second mounting slots 102 are provided on the side of the disc body 1 along the circumferential direction, and four corresponding first connecting sleeves 2 are also provided. Multiple first mounting slots 101 are provided on the side of the disc body 1, and multiple second connecting sleeves 3 are also provided, and they are rotatably installed in the corresponding positions of the first mounting slots 101.
[0077] It should be understood that if the tent only needs to be expanded for a single function, such as simply adding a rain shelter at the entrance or exit, or as... Figure 2 As shown, when connecting and expanding two adjacent tents, only one extension pole 71 needs to be connected to the tent head of a single tent. Therefore, only one second connecting sleeve 3 needs to be installed on the tent head. However, when the tent needs to be expanded for multiple functions or when two or more tents are continuously expanded, the number of second connecting sleeves 3 required on the tent head may need to be multiple. The specific number can be selected according to actual needs, such as two, three, or four.
[0078] Specifically, if the tent needs to be extended and connected, a rain shelter also needs to be added at the entrance and exit points, or as... Figure 4 When expanding three tents consecutively, each tent may require two extension poles 71, thus requiring two second connecting sleeves 3 on the tent head. If the tents need to be extended in three or four directions, the required number of extension poles 71 will be three or four; therefore, the number of second connecting sleeves 3 on the tent head will be three or four. Thus, the specific number and installation position of the second connecting sleeves 3 installed on the side of the tent body 1 can be selected according to actual needs. For example... Figure 11 As shown, two second connecting sleeves 3 are installed on the side of the disk body 1, and the two second connecting sleeves 3 are arranged opposite each other; or three second connecting sleeves 3 are installed on the side of the disk body 1, and adjacent second connecting sleeves 3 are arranged at 120° intervals along the circumferential direction; or four second connecting sleeves 3 are installed on the side of the disk body 1, and adjacent second connecting sleeves 3 are arranged at 90° intervals along the circumferential direction.
[0079] Example 4: Compared with Embodiments 1 to 3, the difference in this embodiment is as follows: Figure 12 and Figure 13 As shown, the second connecting sleeve 3 abuts against the inner wall of the first mounting groove 101 through the upper side of its inner end to form a limiting structure.
[0080] It is understandable that when the second connecting sleeve 3 is in a horizontal state, its upper side is spaced apart from the inner wall of the first mounting groove 101. Thus, when the second connecting sleeve 3 rotates downward around the mounting position, the inner end of the second connecting sleeve 3 will gradually move closer to the inner wall of the first mounting groove 101 until the inner end of the second connecting sleeve 3 abuts against the inner wall of the first mounting groove 101. At this time, the second connecting sleeve 3 reaches the set lower limit of the rotation angle.
[0081] It is important to understand that while the second connecting sleeve 3 can be cylindrical in shape, this would result in point contact between its inner end and the inner wall of the first mounting groove 101, leading to increased wear. Therefore, to reduce wear on the second connecting sleeve 3, the contact between the upper inner end of the second connecting sleeve 3 and the inner wall of the first mounting groove 101 can be adjusted from point contact to line contact or surface contact. For ease of understanding, a detailed description will follow.
[0082] Specifically, such as Figure 12 and Figure 13 As shown, the upper part of the disc body 1 is provided with an opening 600 that connects to the first mounting groove 101, and the second connecting sleeve 3 can be fitted and abutted by the inner end of the sleeve against the edge of the opening 600 through line contact.
[0083] It is understandable that the specific structural type of the second connecting sleeve 3 can vary, as long as the connecting cavity 300 is a cylindrical hole. For example, the second connecting sleeve 3 can be cylindrical in shape, and the opening 600 can be elliptical, so that the inner end of the second connecting sleeve 3 can contact the edge of the opening 600 to the maximum extent. Alternatively, if the inner end cross-section of the second connecting sleeve 3 is rectangular, the opening 600 can also be rectangular, so that one side of the inner end of the second connecting sleeve 3 contacts the edge of the opening 600. The specific structure of the second connecting sleeve 3 and the corresponding shape design of the opening 600 can be selected according to the actual needs of those skilled in the art.
[0084] It is also understandable that, for the second connecting sleeve 3 to make surface contact with the inner wall of the first mounting groove 101 through its inner end, the edge of the opening 600 near the inner end of the second connecting sleeve 3 can be set as an inclined surface that adapts to the outer side of the second connecting sleeve 3, based on the above-mentioned line contact.
[0085] It should be noted that the first mounting groove 101 can be integrally formed on the disc body 1 or it can be separately formed on the disc body 1. For ease of understanding, the specific formation method of the first mounting groove 101 will be described in detail below.
[0086] For the integrally formed first mounting groove 101, a through hole can be provided on the second connecting sleeve 3, and a corresponding through hole can also be provided on the first mounting groove 101. Then, by aligning the through hole of the second connecting sleeve 3 with the through hole of the first mounting groove 101, the rotating shaft 302 can be inserted into the aligned through hole to complete the rotational installation of the second connecting sleeve 3. It should be noted that the opening 600 can be integrally formed with the disc body 1, or it can be processed after the disc body 1 is formed.
[0087] For the first mounting slot 101, which is formed in a split manner, such as Figure 12 and Figure 13 As shown, a mounting opening 103 is provided at a corresponding position on the disc body 1, and a cover plate 6 is detachably mounted on the upper part of the disc body 1. The cover plate 6 is detachably mounted on the disc body 1, and the cover plate 6 and the disc body 1 can cooperate to form a rotating groove for rotatably mounting the rotating shaft 302 provided on the side of the second connecting sleeve 3. The installation steps of the cover plate 6 and the second connecting sleeve 3 are basically the same as the installation steps of the seat plate 4 and the second connecting sleeve 3 in Embodiment 1. For details, please refer to the installation process of the seat plate 4 in Embodiment 1. It should be noted that the opening 600 can be integrally formed with the cover plate 6, or it can be processed after the cover plate 6 is formed.
