Abstract

The utility model relates to the technical field of rod connecting sleeves, in particular to a tent rod connecting sleeve, which is characterized in that a raised line is arranged in the sleeve, an inclined plane A is arranged on one side of the raised line close to a cantilever end by taking the raised line as a demarcation point, and the inclined plane A extends obliquely upwards by taking the lower surface in the sleeve as an initial point; when the tent pole on one side of the cantilever end is inserted into the sleeve along the inclined plane A, due to the existence of the inclined plane A and the inclined plane B, even if an assembly gap exists, stable connection is realized due to more binding surfaces; then, when the tent rod on one side of the fixed end is inserted into the sleeve, the sleeve inclines downwards due to a certain inclination angle gap generated by the assembly gap under the self-weight effect of the tent rod on one side of the cantilever end, but due to the existence of the inclined plane A, the tent rod on one side of the cantilever end is relatively kept in a horizontal state, so that the problem that the tent rod on one side of the cantilever end inclines downwards can be solved.

Description

Technical Field

[0001] This utility model relates to the field of pole connecting sleeve technology, and in particular to a tent pole connecting sleeve. Background Technology

[0002] Most mosquito nets used in daily life are closed structures, consisting of four vertical poles and four horizontal poles combined with the bed surface to form a frame. The mosquito netting is then wrapped around this frame, and one or more exits are made along the sides of the bed for easy access (e.g., ...). Figure 1 (as shown)

[0003] To facilitate entry and exit for people and the taking down and setting up of mosquito nets, the manufacturer designed a cantilevered mosquito net frame structure. This structure uses two vertical poles and a U-shaped tube to form a frame with the bed surface. The mosquito net is then wrapped around the frame. When it needs to be taken down, simply slide the mosquito net, which is fitted over the U-shaped tube, along the curve of the U-shaped tube (e.g., ...). Figure 2 (As shown).

[0004] In actual use, although the cantilever mosquito net frame structure is easier to put up and take down and reduces the number of installation positions, the excessive weight of the front section of the cantilever makes it prone to bending and deformation, which affects the user experience. Furthermore, long-term deformation can lead to permanent deformation of the cantilever rods, resulting in damage and reducing service life.

[0005] To address the aforementioned issues, refer to the prior art patent application No. 201520113711.X, entitled "Connection Structure of Upright and Guide Rail Rod of Floor-Standing Curtain Mosquito Net Support." This application, to solve the problem of downward bending deformation of the cantilever section, includes a positioning sleeve fitted onto the upper part of the upright and a socket connected and fixed to the guide rail rod. The positioning sleeve has a support panel that presses against the end face of the socket, and the socket is connected and fixed to the support panel of the positioning sleeve. By using a positioning sleeve fitted onto the upper part of the upright and connecting it to the socket at the end of the guide rail rod, the advantages of both the floor-standing and guide rail mosquito net are perfectly combined. This not only makes installation simple and convenient, but the positioning sleeve design also provides good reinforcement and enclosure for the upright. Combined with the inner lining support inside the upright, the bending strength of the upright is further improved, preventing deformation due to the small contact area between the curved surface of the circular upright and the support panel of the positioning sleeve, thus providing sufficient support for the entire guide rail support.

[0006] By using a combination of split positioning sleeves, sockets, and support panels to fix the uprights and guide rails, deformation caused by the small contact area between the curved surface of the round upright and the support panel of the positioning sleeve can indeed be avoided. Furthermore, this solution also provides the inspiration to overcome downward bending deformation by utilizing the tilt angle b on the socket.

[0007] Similarly, patent documents for related products in recent years, such as CN00125040.X, CN201220159228.1, and CN201410404476.1, have not made any relevant designs based on the deformation resistance of the cantilever end members in the cantilever structure.

[0008] Therefore, in summary, how to more conveniently and effectively solve the problem of the downward tilt of the cantilever end of the cantilever mosquito net support structure remains an area that needs improvement. Summary of the Invention

[0009] To address the issue of the downward tilt of the cantilever end in the aforementioned cantilever mosquito net support structure, this application modifies the intermediate structure at the connection point of the mosquito net support structure, thereby resolving the downward tilt of the cantilever end in the cantilever mosquito net support structure.

[0010] Among them, the present invention provides a tent pole connecting sleeve for connecting tent poles in a cantilever structure. At least one surface of the inner wall of the sleeve is a sloping surface A, which is used to counteract the downward deformation of the cantilever side tent pole caused by its own weight during use.

[0011] Since the above-mentioned sleeve is designed to be suitable for existing common key structural connections, the shape of the sleeve can be a two-way type (straight pipe or folded pipe) or a multi-way type (such as a three-way pipe). The arrangement of the upper inclined surface A is also different for different shaped sleeves.

[0012] Taking the example of a two-way (straight tube) sleeve installed outside the tent pole, the internal inclined surface A can be set as follows:

[0013] Method 1: An inclined plane A extends from the lower inner surface of the sleeve towards one end of the sleeve;

[0014] Method 2: Starting from a certain position in the middle of the lower inner surface of the sleeve, two inclined planes A extend to both ends of the sleeve respectively;

[0015] Method 3: Two inclined planes A are extended from both ends of the sleeve to a certain position in the middle of its inner upper surface;

[0016] Method 4: Two inclined planes A are extended from a certain position in the middle of the casing towards both ends of the casing, with one inclined plane A on the upper surface and the other inclined plane A on the lower surface. The inclined plane A on the lower surface is used to connect the two inclined planes A that extend from a certain position in the middle of the upper surface to the middle of the casing.

[0017] To enhance the connection stability of the sleeve to the tent pole, a raised strip is provided on the inner wall of the sleeve to limit the movement of the sleeved tent pole.

[0018] Preferably, the convex strip is located at the middle range C of the sleeve; the middle range C occupies 1 / 3 to 1 / 4 of the total length of the sleeve.

[0019] Preferably, the ribs are arranged in a continuous or intermittent ring on the sleeve.

[0020] Preferably, the side of the protrusion closest to the inclined surface A is provided with an inclined surface B that is perpendicular to the inclined surface A.

[0021] Preferably, the inclination angle of the inclined plane is between 1-3° relative to the horizontal placement surface of the sleeve.

[0022] Preferably, the multi-port sleeve is used to radiate outwards from the top of the vertical tent poles to connect multiple horizontal tent poles.

[0023] In addition, the sleeve is connected to a guide hook for installing the leather strap rail, so that the mosquito net can be better installed on the tent pole via the hanging ring.

[0024] Preferably, the guide hook is detachably connected to the sleeve via an extension base; the extension base is used to increase the number of guide hooks and change their distribution position.

[0025] Preferably, the extension base has a triangular structure, with its hypotenuse being a straight line or an arc.

[0026] Preferably, the sleeve has a slot for sliding connection of the expansion base, and the expansion base is slidably connected in the slot through an I-shaped connector at its end.

[0027] Preferably, the convex strip is provided with a receiving groove corresponding to the I-shaped connector.

[0028] The beneficial effects of this utility model are:

[0029] (1) This application takes the square structure of the tent pole as an example, that is, the sleeve to be sleeved is also square, and the size gap between the sleeve and the tent pole is controlled within ±20 mils on one side according to the conventional production standard assembly gap. If the tent pole is inserted into the sleeve, a slope is set on the lower surface of the sleeve and the tent pole in contact. When a tent pole is inserted into the sleeve along the slope, it is not installed as a cantilever structure. There is a certain angle gap between the end face of the tent pole and the reinforcing rib. That is, the end of the tent pole away from the sleeve is raised.

[0030] When a tent pole is inserted into each end of the sleeve to form a cantilever structure, the cantilever tends to tilt due to its own weight. By setting different inclined surfaces, the tilting tendency can be resisted by the inclined surfaces, thereby blocking the tilting tendency of the cantilever due to its own weight. Compared with the obvious drooping of the prior art, this application can keep the cantilever horizontal or even tilted, thus achieving a good effect of resisting or reducing downward tilting.

[0031] (2) In order to achieve that the cantilever structure does not have a downward tilting tendency from the beginning, the initial fixed angle of the first section of the tent pole is upward. Under this method, the above method is adopted when manufacturing the two-way (folded tube) sleeve. Attached Figure Description

[0065] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0066] See Figure 2 It is understood that the cantilever mosquito net has a vertical tent pole 2 on only one side to support the horizontal tent pole 2; the following embodiments are based on the bending connection between the vertical tent pole 2 and the horizontal tent pole 2 as the relatively fixed end and the cantilever end away from the fixed end as the directional basis, and the arrangement of the inclined plane A4 is used as the starting point to explain the implementation of various embodiments.

[0067] In this application, the original whole horizontal tent pole 2 is divided into two or more sections, and then the multiple sections of tent pole 2 are quickly connected by sleeves 3 during the actual installation process. For ease of understanding, the following embodiments only show the way two sections of tent pole 2 are connected by sleeves 3. The connection between multiple sections of tent pole 2 can be done in the same way.

[0068] Since sleeve 3 is used to connect to tent pole 2, sleeve 3 can be a two-way type (straight tube or folded tube), or a three-way type or a multi-way type;

[0069] The bevel A4 is set differently for different models of sleeve 3;

[0070] When the two-way (straight tube) sleeve 3 is fitted outside the tent pole 2, its internal inclined surface is set as follows;

[0071] Example 1, as described in [reference] Figure 3 There is no protrusion 5 inside the sleeve 3. When a tent pole 2 is inserted into each side of the sleeve 3, the tent pole 2 near the fixed end remains horizontal. Under the weight of the tent pole 2 on the cantilever end side, the sleeve 3 tilts downward due to a certain tilting gap caused by the assembly gap (the assembly gap is more obvious in the figure for easy display, but the actual assembly gap is controlled within 2±0.1mm on one side). However, due to the presence of the inclined surface A4, the tent pole 2 on the cantilever end side remains relatively horizontal, thus basically solving the tilting problem. At this time, the ends of the two tent poles 2 that are in contact with each other abut against each other and form a triangular structure with the assembly gap to ensure the stability of the assembly.

[0072] Example 2, based on Example 1, includes a protrusion 5 inside the sleeve 3. Using the protrusion 5 as a dividing point, a slope A4 is provided on the side of the protrusion 5 facing the cantilever end. The slope A4 extends obliquely upwards from the lower inner surface of the sleeve 3 (see...). Figures 4-5 ); the convex strip 5 at this time forms a right-angled trapezoidal structure.

[0073] When the tent pole 2 on the cantilever end side is inserted into the sleeve 3 along the inclined plane A4, the presence of inclined planes A4 and B6 ensures a stable connection even with assembly gaps due to the increased contact surface. Then, when the tent pole 2 on the fixed end side is inserted into the sleeve 3, similar to Embodiment 1, the sleeve 3 tilts downwards due to the self-weight of the tent pole 2 on the cantilever end side, caused by a certain angle gap generated by the assembly gap. However, due to the presence of inclined plane A4, the tent pole 2 on the cantilever end side remains relatively horizontal, thus solving the problem of the tent pole 2 tilting downwards on the cantilever end side. However, due to the setting of the protrusion 5, the sleeve 3 will not move around on the tent pole 2 during use.

[0074] Example 3, based on Example 2, includes a protrusion 5 inside the sleeve 3. With the protrusion 5 as the dividing point, inclined surfaces A4 are provided on both sides of the sleeve 3. The inclined surfaces A4 are symmetrically arranged about the sleeve 3, and both inclined surfaces A4 extend obliquely upwards from the lower inner surface of the sleeve 3 (see Example 2). Figure 6-7 ); the convex strip 5 at this time has an equilateral trapezoidal structure.

[0075] When the tent pole 2 on one side of the cantilever end is inserted into the sleeve 3 along the inclined plane A4, due to the presence of inclined plane A4 and inclined plane B6, even if there is an assembly gap, a stable connection is achieved due to the increased contact surface, and a relative initial upward tilt occurs.

[0076] Then, when the tent pole 2 on the fixed end side is also inserted into the sleeve 3 along the inclined surface A4, unlike in Embodiment 2, the tent pole 2 on the fixed end side abuts against the inclined surface B6 of the protrusion 5, thus forming an upward tilt in the initial state of the sleeve 3. At this time, even under the self-weight of the tent pole 2 on the cantilever end side, the upward tilt of the sleeve 3 in the initial state makes the tent pole 2 on the cantilever end side relatively tilted, which can resist the downward tilting trend caused by its own weight. Thus, the tilting trend of the cantilever side due to its own weight is blocked. Compared with the obvious drooping of the prior art, this embodiment can make the tent pole 2 on the cantilever end side at least keep in a horizontal state, or even tilted up. Thus, it can also solve the problem of downward tilting deformation of the tent pole 2 on the cantilever end side.

[0077] In embodiment four, the sleeve 3 is provided with a protrusion 5. With the protrusion 5 as the dividing point, inclined surfaces A4 are provided on both sides of the protrusion 5. The inclined surfaces A4 are symmetrically arranged about the protrusion 5, and the directions of the two inclined surfaces A4 converge obliquely towards the protrusion 5 with the end of the sleeve 3 as the initial point (see...). Figure 8-9 );

[0078] Unlike Example 3, the position and tilt direction of the inclined plane A4 have been changed;

[0079] When the tent pole 2 on one side of the cantilever end is inserted into the sleeve 3 along the inclined plane A4, due to the presence of inclined plane A4 and inclined plane B6, even if there is an assembly gap, a stable connection is achieved due to the increased contact surface, and a relative initial upward tilt occurs.

[0080] Then, when the tent pole 2 on the fixed end side is also inserted into the sleeve 3 along the inclined surface A4, the tent pole 2 on the fixed end side abuts against the inclined surface B6 of the protrusion 5, thus forming the sleeve 3 in the initial state of being tilted upwards. At this time, even under the action of the self-weight of the tent pole 2 on the cantilever end side, because the sleeve 3 is tilted upwards in the initial state, the tent pole 2 on the cantilever end side is relatively tilted upwards, which can resist the downward tilting trend caused by its own weight. Thus, the tilting trend of the cantilever side due to its own weight is blocked. Compared with the obvious drooping of the prior art, this embodiment can make the tent pole 2 on the cantilever end side at least keep in a horizontal state, or even tilted upwards; thus, it can also solve the problem of downward tilting deformation of the tent pole 2 on the cantilever end side.

[0081] In Example 5, the sleeve 3 is provided with a protrusion 5. With the protrusion 5 as the dividing point, inclined surfaces A4 are provided on both sides of the protrusion 5. The inclined surface A4 away from the cantilever end extends obliquely downwards from the upper inner surface of the sleeve 3; the inclined surface A4 near the cantilever end extends obliquely upwards from the lower inner surface of the sleeve 3 (see...). Figure 10-11 );

[0082] Unlike Embodiment 1, a more stable connection is achieved by setting an inclined surface A4 on the upper wall of the sleeve 3 on one side of the fixed end and using a parallelogram-shaped protrusion 5, while maintaining a basically horizontal state.

[0083] Example 6: The inclined surface A4 of the two-way (bent-pipe type) sleeve 3 can be configured as follows:

[0084] Based on the above-mentioned two-way (straight pipe) embodiment five, the design is based on the 5th convex strip as the reference (see...). Figure 12 At this time, the two-way (folded tube) sleeve 3 has an initial tilt angle compared to the vertical tent pole 2. Therefore, when the two-way (straight tube) sleeve 3 is used to connect the multi-segment combined tent pole 2, the first segment of the horizontal tent pole 2 is tilted upward, thus providing more effective resistance to or reducing downward deformation for the subsequent connected multi-segment tent pole 2.

[0085] To further improve the bending strength of the connector, the right-angle turn can be a rounded structure (see...). Figure 13 );

[0086] If the convex strip 5 is used in the same set, then the convex strip 5 is arranged in a diamond shape (see...). Figure 14 );

[0087] The original one group can be changed to two groups, and the inclined plane B6 structure can be omitted. Instead, a parallelogram arrangement can be used as in Example 5 (see [example]). Figure 12 ).

[0088] In Example 7, for the multi-port sleeve 3, the specific configuration can be analogous to the above-described inclined plane configuration; among them, the three-way sleeve 3 is the most common; while the four-way sleeve 3, in conjunction with the three-way pipe and the two-way pipe, is used to divide adjacent beds and assemble the curtain 1 (see...). Figure 15 This can be applied to hospital ward beds, etc.

[0089] Example 8, based on Examples 1 to 7 above, is implemented with the tent pole 2 having a square cross-section and being inserted into a similarly square sleeve 3. The dimensional gap between the sleeve 3 and the tent pole 2 can be controlled within 2 ± 0.1 mm on one side according to conventional production standards. In specific implementation, the sleeve 3 can be manufactured into a circular structure to match the circular tent pole 2 for connection.

[0090] Example 9, see appendix Figure 16 Compared to embodiments one through seven, during the production process, the method of inserting the tent pole 2 into the sleeve 3 can be adjusted to have the tent pole 2 sleeved outside the sleeve 3. In this case, the corresponding inclined surface A4 outside the sleeve 3 can be set as follows:

[0091] An inclined surface A4 is provided on the upper surface of the sleeve 3 near the fixed end. When the tent pole 2 on the fixed end side is inserted into the sleeve 3, the presence of the inclined surface A4 causes the other side of the bracket connector to tilt upward. Then, when the tent pole 2 on the cantilever end side is inserted into the sleeve 3, there is an initial upward angle. At this time, even if there is downward tilting due to the assembly gap, it can basically maintain a horizontal state or even an upward tilting state, thereby resisting the downward tilting deformation problem of the tent pole 2 on the cantilever end side due to its own weight.

[0092] At this point, the above effect can be achieved either by not setting the protrusion 5 or by setting a parallelogram-shaped protrusion 5.

[0093] Similarly, the inclined surface A4 setting method of the same embodiments one to seven can also be applied to the outside of the sleeve 3.

[0094] Example 10: In the above Examples 1 to 9, the inclined plane A4 is considered to have a smooth connection and stability between the sleeve 3 and the tent poles 2 on both sides. It is better to control the angle of the inclined plane A4 between 1 and 3°. The optimal angle is 2°. At this time, the ratio of the two perpendicular sides of the triangle on one side of the inclined plane is 1:27.8.

[0095] For example, see Figure 17 When the length of the longer side 'a' of the two perpendicular sides of the triangle is 5cm, the length of the bracket connector including the reinforcing rib is not less than 10cm, and the length of the shorter side 'b' of the two perpendicular sides of the triangle is approximately 0.18cm. This dimension is within the range of 2+0.5mm on one side of the standard assembly gap.

[0096] In Example 11, in addition to its limiting function, the protruding strip 5 can also enhance the bending resistance of the sleeve 3. By placing the protruding strip 5 at the middle range C of the sleeve 3, and the middle range C accounting for 1 / 3-1 / 4 of the total length, the sleeve 3 can provide better support for the tent poles 2 on both sides. At this time, the size of the sleeve 3 extending to both sides based on the protruding strip 5 should be changed according to the length of the tent poles 2 connected to both sides.

[0097] However, regardless of the method, the protrusion 5, which is usually set in the middle of the bracket connector, can be flexibly set in the left and right range of 1 / 3 to 1 / 4 of the middle of the sleeve 3, so as to avoid the problem of insufficient support and slippage caused by the size of the sleeve 3 for connecting the tent pole 2 being too small.

[0098] Example 12, see Figure 2 and Figure 18In addition to connecting the tent poles 2, the sleeve 3 can also be used to slide and install the tent 1. The sleeve 3 is connected to a guide hook 7, which can be integrally formed with the sleeve 3. The guide hook 7 is used to install the leather guide rail 8. The tent 1 is slidably installed on the leather guide rail 8 through the hook, thereby realizing the sliding opening and closing of the tent 1.

[0099] Example 13, see Figure 19 and Figure 20 Unlike embodiment 12, the guide hook 7 is fixedly connected to the sleeve 3 by a base 9; the base 9 is used to expand the number of guide hooks 7 and change the distribution position of the guide hooks 7.

[0100] Example 14, see Figures 21-26 Unlike embodiment 13, the base 9 is detachably connected to the sleeve 3. The sleeve 3 has a slot 10 for sliding connection of the base 9. The base 9 is slidably connected to the slot 10 through the connector 11 at the end. Similarly, the guide hook 7 can also be connected to the base 9 or the sleeve 3 through the connector 11. The connection method between the connector 11 and the guide hook 7 includes but is not limited to threaded connection, welding, riveting or plugging.

[0101] Example 15, see Figure 27 Based on embodiment fourteen, the convex strip 5 is provided with a receiving groove 12 corresponding to the connector to accommodate the connector and avoid obstructing the insertion of the tent pole 2.

[0102] Example 16, see Figures 28-30 To better achieve stable assembly of the tent pole 2, the sleeve 3 is provided with an elastic protrusion 13, and the sleeve 3 is provided with a U-shaped groove 14 around the elastic protrusion 13 for fastening the tent pole 2.

[0103] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the invention is limited to these examples; within the framework of the invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity.
