[0055] The present invention will be further described below with reference to the drawings.

[0056] Embodiment 1, as Figure 1-13As shown, there is a pipe 100 and an insertion pipe 200 that is inserted into the pipe 100 and can slide up and down. The wall of the pipe 100 is generally circular, but has a groove 10-2 that penetrates through the upper and lower ends. Since convex and concave are relative, the wall of the pipe except for the groove 10-2 can be regarded as a convex rib 10-1. The shape of the insertion pipe 200 is similar to that of the pipe, and its wall also has an insertion pipe groove 20-2 and a so-called insertion pipe convex rib 20-1. A locking hole 101 that extends longitudinally across the convex rib 10-1 and the groove 10-2 is opened at one end close to the pipe 100. A row of multiple insertion pipe locking holes 201 that can respectively correspond to the locking hole 101 are opened on the insertion pipe 200. Two opposite clamping holes 102 are opened on the wall of the pipe 100 at one end close to the long oval hole 103 and outside the long oval hole 101. The convex rib 10-1 and the groove 10-2 have a smooth transition, and the insertion pipe convex rib 20-1 and the insertion pipe groove 20-2 have a smooth transition.

[0057] A rotary locking seat corresponding to the foregoing pipe and insertion pipe, including

[0058] An upper seat body 300, whose inner cavity has an upper seat body groove 30-1 and an upper seat body convex rib 30-2 that are equal in number to the convex rib 10-1 and the groove 10-2, i.e., one each, similar in shape, and suitable for insertion; the outer wall is a circular surface, and an upper seat body long oval hole 301 that is the same in shape and position as the locking hole 101 is opened on the circular surface;

[0059] A lower seat body 400, fixedly connected to the lower end of the upper seat body 300; the inner cavity has a lower seat body groove 40-1 and a lower seat body convex rib 40-2 that are equal in number to the insertion pipe convex rib 20-1 and the insertion pipe groove 20-2, i.e., one each, similar in shape, and suitable for insertion; an annular skirt 401 extends upward at the upper end, and the annular skirt 401 is suitable for covering the circular surface outer wall of the upper seat body 300 but the upper end does not exceed the lower edge of the upper seat body long oval hole 301;

[0060] An annular sleeve 500, sleeved outside the upper seat body 300 and the lower seat body 400, and a radial lock tongue 501 is fixedly arranged on the inner wall. The lock tongue 501 can extend into the upper seat body long oval hole 301, the locking hole 101, and one of the insertion pipe locking holes 201, and the end exceeds the insertion pipe locking hole 201 located at the insertion pipe convex rib 20-1 and does not exceed the insertion pipe locking hole 201 located at the insertion pipe groove 20-2.

[0061] Actually, the above structure can already meet the basic functions. However, in order to better achieve the effects of the present invention, the following technical solutions can be added on the basis of the above structure:

[0062] A part of the circular ring skirt 401 extends upward to form an intermediate plate 403 between the lower seats, and an insertion hole 404 for the upper seat is formed at the end of the intermediate plate 403 between the lower seats; the inner wall of the circular ring sleeve 500 extends downward while avoiding the intermediate plate 403 between the lower seats to form an intermediate plate 502 of the ring sleeve, and three insertion holes 503 of the ring sleeve are formed at the end of the intermediate plate 502 of the ring sleeve. The purpose of providing three is to adjust the elastic force of the spring. A serpentine spring 600 is placed in the cavity between the upper seat 300 and the circular ring sleeve 500. One end of the serpentine spring 600 is inserted into one of the insertion holes 404 for the upper seat, and the other end is inserted into one of the insertion holes 503 of the ring sleeve. The function of the spring is to automatically reset the circular ring sleeve to the locked state.

[0063] The upper end of the upper seat 300 extends outward to form a flange 302 of the upper seat; the lower end of the lower seat 400 extends outward to form a flange 402 of the lower seat; the circular ring sleeve 500 is located between the flange 302 of the upper seat and the flange 402 of the lower seat. In this way, the circular ring sleeve 500 will not come out from above or below.

[0064] A screw hole 303 is formed at the lower end of each rib 30-2 of the upper seat, and a through hole 405 is formed on the rib 40-2 of the lower seat. After a screw 406 passes through the through hole 405, it is screwed into the screw hole 303 to fixedly connect the lower seat 400 and the upper seat 300. Since there is only one rib 30-2 of the upper seat and one rib 40-2 of the lower seat in this embodiment, three clamping heads 304 extend outward from the upper seat 300 away from the rib 30-2 of the upper seat, and three corresponding card slots 407 are formed on the upper seat 300. This avoids the problem that fixing the upper seat and the lower seat with only one screw 406 is not firm enough. When there are more than two ribs 30-2 of the upper seat and ribs 40-2 of the lower seat, two screws can meet the fixing requirements, and there is no need to provide the clamping heads 304 and the card slots 407.

[0065] On the inner wall of the upper seat 300 corresponding to the position of the clamping hole 102, a clamping post 306 extends inward, and strength release grooves 305 are formed on the wall of the upper seat 300 on both sides of the clamping post 306 so that the wall of the upper seat 300 at this place has elasticity and is suitable for the clamping post 306 to be inserted into the clamping hole 102. In this way, the upper seat 300 is fixedly connected to the pipe.

[0066] The upper seat grooves 30-1 and the upper seat ribs 30-2, which are equal in number, similar in shape and suitable for plugging, to the ribs 10-1 and the grooves 10-2, are in smooth transition, and the lower seat grooves 40-1 and the lower seat ribs 40-2, which are equal in number, similar in shape and suitable for plugging, to the ribs 20-1 of the insertion pipe and the grooves 20-2 of the insertion pipe, are in smooth transition.

[0067] For example, in practice, in order to facilitate the adjustment of the height of the tent, each column of the tent uses the pipe material and the insertion pipe of this embodiment. A rotary locking seat is installed at the lower end of the pipe material. Hold the circular ring sleeve 500 of the rotary locking seat with the right hand, hold the insertion pipe 200 with the left hand, rotate the circular ring sleeve 500 clockwise, so that the locking tongue 501 rotates from the right side of the long circular hole 301 of the upper seat body, the locking hole 101 and one of the insertion pipe locking holes 201 to the left side. At this time, the end of the locking tongue 501 does not contact the insertion pipe, and the insertion pipe is in a state where it can only slide up and down. Hold the insertion pipe 200 with the left hand and pull it up and down. After adjusting to the appropriate height, release the right hand. The locking tongue 501 enters another corresponding insertion pipe locking hole 201 and rotates to the right side of the insertion pipe locking hole under the action of the spring. At this time, the locking tongue enters the inner cavity of the insertion pipe, locking the insertion pipe so that it cannot slide up and down. If you want to continue adjusting, repeat the above steps.

[0068] Embodiment 2, as Figure 6-8 As shown in FIGS. 14-21, it includes a pipe material 100 and an insertion pipe 200 inserted into the pipe material 100 and capable of sliding up and down. The pipe wall of the pipe material 100 is roughly cross-shaped, having 4 grooves 10-2 penetrating through the upper and lower ends, and ridges 10-1 alternating with the 4 grooves 10-2. The shape of the insertion pipe 200 is similar to that of the pipe material, and the pipe wall also has 4 insertion pipe grooves 20-2 and 4 insertion pipe ridges 20-1. A locking hole 101 is opened at one end close to the pipe material 100, with a long direction spanning the ridge 10-1 and the groove 10-2. A row of multiple insertion pipe locking holes 201 capable of corresponding to the locking hole 101 respectively are opened on the insertion pipe 200. Two opposite clamping holes 102 are opened on the pipe wall of the pipe material 100 outside the long circular hole 103 and outside the locking hole 101. The ridge 10-1 and the groove 10-2 are in smooth transition, and the insertion pipe ridge 20-1 and the insertion pipe groove 20-2 are in smooth transition.

[0069] A rotary locking seat corresponding to the aforementioned insertion pipe, including

[0070] An upper seat body 300, whose inner cavity has the same number as the ridge 10-1 and the groove 10-2, that is, one each, with a similar shape and suitable for plugging, upper seat body grooves 30-1 and upper seat body ridges 30-2; the outer wall is a circular surface, and a long circular hole 301 of the upper seat body with the same shape and position as the locking hole 101 is opened on the circular surface;

[0071] The lower seat body 400 is fixedly connected to the lower end of the upper seat body 300; the inner cavity has a lower seat body groove 40-1 and a lower seat body rib 40-2 that are equal in number to the insertion pipe rib 20-1 and the insertion pipe groove 20-2 of the insertion pipe, i.e., one each, similar in shape, and suitable for insertion; the upper end extends upward to form a circular ring skirt 401, and the circular ring skirt 401 is suitable for covering the outer wall of the circular surface of the upper seat body 300 but the upper end does not exceed the lower edge of the long circular hole 301 of the upper seat body;

[0072] The circular ring sleeve 500 is sleeved outside the upper seat body 300 and the lower seat body 400, and a radial locking tongue 501 is fixedly arranged on the inner wall. The locking tongue 501 can extend into the long circular hole 301 of the upper seat body, the locking hole 101, and one of the insertion pipe locking holes 201, and the end exceeds the insertion pipe locking hole 201 located at the insertion pipe rib 20-1 and does not exceed the insertion pipe locking hole 201 located at the insertion pipe groove 20-2.

[0073] Actually, the above structure can already meet the basic functions. However, in order to better achieve the effects of the present invention, the following technical solutions can be added on the basis of the above structure:

[0074] A part of the circular ring skirt 401 extends upward to form an intermediate plate 403 between the seat bodies. An insertion hole 404 for the upper seat body is opened at the end of the intermediate plate 403 between the seat bodies; the inner wall of the circular ring sleeve 500 extends downward while avoiding the intermediate plate 403 between the seat bodies to form an intermediate plate 502 of the ring sleeve. Three insertion holes 503 of the ring sleeve are opened at the end of the intermediate plate 502 of the ring sleeve. The purpose of opening three is to adjust the elastic force of the spring. A serpentine spring 600 is placed in the cavity between the upper seat body 300 and the circular ring sleeve 500. One end of the serpentine spring 600 is inserted into one of the insertion holes 404 for the upper seat body, and the other end is inserted into one of the insertion holes 503 of the ring sleeve. The function of the spring is to automatically reset the circular ring sleeve to the locked state.

[0075] The upper end of the upper seat body 300 extends outward to form an upper seat body flange 302; the lower end of the lower seat body 400 extends outward to form a lower seat body flange 402; the circular ring sleeve 500 is located between the upper seat body flange 302 and the lower seat body flange 402. In this way, the circular ring sleeve 500 will not fall out from above or below.

[0076] Screw holes 303 are respectively opened at the lower ends of the 4 upper seat body ribs 30-2, through holes 405 are respectively opened on the 4 lower seat body ribs 40-2, and 4 screws 406 pass through the through holes 405 and are screwed into the screw holes 303 to fixedly connect the lower seat body 400 and the upper seat body 300.

[0077] On the inner wall of the upper seat body 300 corresponding to the position of the clamping hole 102, a clamping post 306 extends inwards. Strength release grooves 305 are formed in the body walls of the upper seat body 300 on both sides of the clamping post 306 so that the body wall of the upper seat body 300 at this place has elasticity and is suitable for the clamping post 306 to be inserted into the clamping hole 102. In this way, the upper seat body 300 is fixedly connected to the pipe.

[0078] The upper seat body grooves 30-1 and upper seat body ribs 30-2, which are equal in number, similar in shape and suitable for insertion, to the ribs 10-1 and grooves 10-2 are in smooth transition. The lower seat body grooves 40-1 and lower seat body ribs 40-2, which are equal in number, similar in shape and suitable for insertion, to the insertion pipe ribs 20-1 and insertion pipe grooves 20-2 are in smooth transition.

[0079] The usage method is the same as that of Embodiment 1, so it will not be elaborated here.

[0080] Embodiment 3, as Figure 14 、 18 、shown in Figures 19, 22-27, a sliding hinge seat that can be fixed at a certain position of a pipe. Similar to Embodiment 2, the difference is that the lower seat body 400 is fixedly connected to the lower end of the upper seat body 300; the inner cavity has lower seat body grooves 40-1 and lower seat body ribs 40-2 that are equal in number, similar in shape and in clearance fit to the ribs 10-1 and grooves 10-2; the upper end extends upwards to form a circular ring skirt 401, and the circular ring skirt 401 is suitable for covering the outer wall of the circular surface of the upper seat body 300 but the lower end does not exceed the upper edge of the long circular hole 301 of the upper seat body; a circular ring sleeve 500 is sleeved outside the upper seat body 300 and the lower seat body 400, and a radial locking tongue 501 is fixedly arranged on the inner wall. The end of the locking tongue 501 exceeds the locking hole 101 at the rib 10-1 and does not exceed the locking hole 101 at the groove 10-2. Two hinge seats 307 with hinge axes perpendicular to each other in the axial direction are fixedly arranged on the upper seat body flange 302. Since the shapes of the inner cavities of the upper seat body and the lower seat body correspond to the outer shape of the pipe, as shown in Figure 27 Figure, this sliding hinge seat can move up and down along the pipe; when the locking tongue is locked, the sliding hinge seat can be fixed at the position of a certain locking hole 101 on the pipe 100. This structure is like the sliding hinge seat on an umbrella handle, which is convenient for retracting and extending.

[0081] The above are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention; any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make many possible changes or modifications to the technical solution of the present invention by using the methods and technical contents disclosed above, or modify it into equivalent embodiments with equivalent changes.
