DETAILED DESCRIPTION
[0052] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0053] In this document, the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present application.
[0054] Figures 1 to 23 The drawings are drawn in true proportion. To keep the specification concise, the proportions of each component are not listed one by one, but the proportions and positions of each component should be regarded as part of the content of this specification. Example 1
[0055] This embodiment provides a tent with an unfolded state and a folded state, and the tent is used for outdoor activities to provide shelter, such as sunshade or rain shelter. Figures 1 to 3As shown, the tent 100 includes a top frame 200 and a plurality of support legs 300 supporting the top frame 200. The top frame 200 is used to open or fix the top tarpaulin of the tent 100. The tent 100 may also include a cloth located on the side of the tent 100, and the cloth is spread out between adjacent support legs 300. The number of support legs 300 is not less than 3, such as 4 as shown in the accompanying drawings. The support legs 300 extend generally up and down, with the lower end of the support leg 300 standing on the ground and the upper part connected to the top frame 200. In some examples, the support legs 300 are telescopic support legs 300, including an upper rod and a lower rod that can be slidably connected (e.g., sleeved), so that the length of the support legs 300 can be adjusted. Figure 1 In the unfolded state shown, the support legs 300 are extended to place the top frame 200 in a higher position. Figure 1 The lower rods of the supporting legs 300 are not shown. Figure 3 In the folded state shown, the support legs 300 are retracted to reduce the overall folded height of the tent 100 for easy storage, transportation and storage.
[0056] The interior space 400 of the tent 100 is defined by the top frame 200 and the support legs 300. The space directly below the top frame 200 is the interior space 400 of the tent 100. The top frame 200 includes a plurality of foldable top rod units 201, which are connected to a central lock 5 located at the top of the center of the tent 100. The number of top rod units 201 corresponds to the number of support legs 300, and the outer end of each top rod unit 201 is connected to the upper part of a corresponding support leg 300. The top frame 200 also includes a plurality of external telescopic units 202, and an external telescopic unit 202 is connected to the upper part of each two adjacent support legs 300. The external telescopic units 202 can be folded and unfolded laterally, so that the support legs 300 are moved away from each other during the unfolding process and the support legs 300 are moved closer to each other during the folding process. For example, the external telescopic unit 202 is composed of a plurality of cross-shaped connecting rod assemblies hinged in sequence, and each cross-shaped connecting rod assembly includes two connecting rods 301 hinged to each other at the middle. In the cross-shaped connecting rod assembly connected to the supporting leg 300, one end of the upper connecting rod 301 is hinged to the upper end of the supporting leg 300, and one end of the lower connecting rod 301 is hinged to the sliding sleeve 302 on the supporting leg 300; when folding or opening, the sliding sleeve 302 can slide up and down on the supporting leg 300, and the outer telescopic unit 202 is relatively unfolded or folded.
[0057] Each push rod unit 201 includes an inner push rod 1 and an outer push rod 2 that can be turned relative to each other. The inner push rod 1 of each push rod unit 201 is rotatably connected through a center lock 5, and the outer end of the outer push rod 2 is hinged to the upper end of the support leg 300. In the embodiment shown in the drawings, the outer end of the inner push rod 1 and the inner end of the outer push rod 2 of each push rod unit 201 are directly pivoted to each other, the inner end of the inner push rod 1 is pivoted to the center lock 5, and the outer end of the outer push rod 2 is pivoted to the upper end of the support leg 300.
[0058] The tent 100 also includes an opening drive member, which is arranged on at least one inner top rod 1 or a center lock 5, so as to allow the outer top rod 2 or the opening drive member to be operated outside the internal space 400 during the process of converting the tent 100 from a folded state to an unfolded state, so that the inner top rod 1 is turned upward relative to the outer top rod 2 and unfolded. Specifically, in the example shown in the drawings, the opening drive member is a first elastic member 4, which is arranged on the center lock 5; when a user stands outside the tent 100, when the center lock 5 is not in a locked state, the tent 100 can be unfolded or folded by rotating the outer top rod 2.
[0059] When the tent 100 is transformed from the folded state to the unfolded state, the outer top rod 2 is operated or the driving member is opened outside the internal space 400 to lock each top rod unit 201 with the central lock 5. Specifically, in the example shown in the drawings, the user stands outside the tent 100 and rotates the outer top rod 2 to lock the central lock 5, that is, to lock each top rod unit 201, so that the tent 100 is stably in the unfolded state.
[0060] The first elastic member 4 can be a compression spring to provide assistance for the inner push rod 1 to flip upward and open. When the tent 100 is in the folded state, the first elastic member 4 is in a deformed state to push the inner push rod 1 to flip upward when the outer push rod 2 is operated.
[0061] Recombination Figures 4 to 14 As shown, the center lock 5 includes a top cap 51 and a slider 52 that moves up and down relative to the top cap 51. The top cap 51 is located above the slider 52, and the inner top rod 1 of each top rod unit 201 is rotatably connected to the top cap 51. Each top rod unit 201 also includes an inclined rod 3, the outer end of the inclined rod 3 is rotatably connected to the inner top rod 1, the inner end of each inclined rod 3 is rotatably connected to the slider 52, and the first elastic member 4 is connected to the slider 52. In the example shown in the accompanying drawings, the first elastic member 4 is arranged between the top cap 51 and the slider 52. When the tent 100 is in the unfolded state, the top cap 51 and the slider 52 have a first spacing, and the first elastic member 4 is in the original state, that is, no deformation occurs; when the tent 100 is in the folded state, the top cap 51 and the slider 52 have a second spacing, the first elastic member 4 is in a compressed state, and the first spacing is greater than the second spacing.
[0062] Furthermore, the first elastic member 4 is sleeved on a center rod 53, the center rod 53 and the top cap 51 are fixedly connected or integrated, and the center rod 53 extends vertically downward from the top cap 51. The slider 52 is slidably arranged on the center rod 53, preferably sleeved on the center rod 53. The compression spring as the first elastic member 4 is sleeved on the center rod 53, with its upper end on the top cap 51 and its lower end against the slider 52. When the tent 100 is folded, the slider 52 moves upward, that is, approaches the top cap 51, the distance between the two becomes shorter, and the compression spring is compressed. When the tent 100 is unfolded, the user rotates the outer push rod 2 until the elastic reset force of the compression spring is sufficient to overcome the constraint of the deadweight of the rod, and the compression spring pushes the slider 52 to move away from the top cap 51, and the distance between the two becomes larger, so that the inner end of the inner push rod 1 moves upward relative to the slider 52, and the inner push rod 1 flips upward and opens.
[0063] When the tent 100 is transformed from the unfolded state to the folded state, the center lock 5 is unlocked and placed in a holding state (eg, Figures 7 and 8 and Figures 10 to 14 As shown in FIG. 4 ), the outer push rod 2 is then operated outside the inner space 400 or the driving member is opened to convert the center lock 5 into an unlocked state, and the push rod units 201 are brought closer to each other. Specifically, when the tent 100 is in the unfolded state, the center lock 5 is in the locked state, as shown in FIG. Figure 6 The tent 100 is in a folded state, and the center lock 5 is in an unlocked state. Fig. 9 During the folding process of the tent 100, the center lock 5 also has a holding state between the locked state and the unlocked state, such as Figures 7 and 8 and Figures 10 to 14 In this holding state, the tent 100 can still be maintained in the unfolded state, but a small force applied to the poles of the tent 100 can cause the tent 100 to fold under its own weight (for example, by shaking or rotating one of the outer top poles 2), and the center lock 5 is converted to the unlocked state.
[0064] The center lock 5 further includes a locking member, which is movably disposed on the center pole 53. When the center lock 5 is in a locked state, the locking member and the slider 52 are locked with each other to provide a first locking force that keeps the tent 100 in the deployed state. When the center lock 5 is in an unlocked state, the locking member and the slider 52 are disengaged. When the center lock 5 is in a holding state, the locking member and the slider 52 are in contact or locked with each other to provide a second locking force that is less than the first locking force, so that the tent 100 is maintained in the deployed state, and the user is allowed to disengage the locking member from the slider 52 when operating the outer top pole 2 outside the internal space 400, so that the center lock 5 is converted from the holding state to the unlocked state.
[0065] The locking member includes a handle 54 movably mounted on the center rod 53. The handle 54 can rotate and move up and down relative to the slider 52. The handle 54 is provided with a locking protrusion 541, and the slider 52 is provided with a locking groove 521 (such as Figure 5 As shown in FIG. 5 ), when the locking protrusion 541 is located in the locking groove 521, the center lock 5 is in a locked state. The slider 52 is also provided with a limiting groove 523, which is located below the locking groove 521 and is connected to each other through a sliding groove 522. Figure 8 and Fig.14 As shown, the limiting groove 523 has an upper groove wall 523a and an open bottom 523b. After the locking protrusion 541 enters the limiting groove 523, the center lock 5 is in a holding state. At this time, the locking protrusion 541 abuts against the upper groove wall 523a and moves from the bottom 523b of the limiting groove 523 to the bottom of the slider 52 after operating the outer push rod 2. The slide groove 522 generally extends in the up-down direction, and the locking groove 521 and the limiting groove 523 extend laterally to the same side from the upper end and the lower end of the slide groove 522 respectively. In the embodiment shown in the drawings, the locking groove 521 extends horizontally from the upper end of the slide groove 522, and the limiting groove 523 extends horizontally from the lower end of the slide groove 522, and the locking groove 521 and the limiting groove 523 are on the same side of the slide groove 522. The upper part of the handle 54 can be inserted into the slider 52, and the locking protrusion 541 is provided on the upper part of the handle 54; when the center lock 5 is in the locked state and the holding state, the upper part of the handle 54 is inserted into the slider 52 and is clamped between the slider 52 and the center rod 53, as shown in FIG. Fig.11 and Fig.13 shown.
[0066] The center lock 5 further includes a second elastic member 543, which is disposed between the handle 54 and the limit section 531 on the center rod 53. When in the holding state, the second elastic member 543 is in a deformed state to prevent the locking protrusion 541 from disengaging downward from the bottom 523b of the limit groove 523. The limit section 531 is fixed to the lower part of the center rod 53, the handle 54 is sleeved on the center rod 53, and the limit section 531 is located inside the handle 54. The second elastic member 543 is a compression spring, which is sleeved on the center rod 53, with the upper end abutting against the top of the handle 54 and the lower end abutting against the limit section 531. When the handle 54 is pulled downward to make the locking protrusion 541 slide downward along the slide groove 522 to the position of the limiting groove 523, the second elastic member 543 is in a deformed state; after the handle 54 is turned to enter the limiting groove 523, the elastic force of the second elastic member 543 has a tendency to push the handle 54 to move upward and reset, so that the locking protrusion 541 can be pressed against the upper groove wall 523a of the limiting groove 523, and thus will not unexpectedly move downward and detach from the bottom 523b of the limiting groove 523. That is, the center lock 5 is maintained in a holding state by the second elastic member 543, so that the user can move to the outside of the tent 100 after operating the handle 54, and then operate the outer top rod 2 to completely fold the tent 100, at which time the center lock 5 is converted into an unlocked state.
[0067] like Figure 8As shown, the locking groove 521 has an open end 521a and a closed end 521b opposite to the open end 521a. The slider 52 also has a guide slope 524 facing downward, and the guide slope 524 extends downward from the open end 521a of the locking groove 521. During the unfolding of the tent 100, the guide slope 524 contacts and enters the locking protrusion 541 into the open end 521a of the locking groove 521. The bottom of the slider 52 has a notch or channel facing the guide slope 524. During the unfolding of the tent 100, the locking protrusion 541 enters and contacts the guide slope 524 through the notch or channel. Under the action of the guide slope 524, the handle 54 moves up and rotates, and the locking protrusion 541 enters the open end 521a of the locking groove 521 along the guide slope 524. The guide slope 524 can be a part of the groove wall of the slide groove 522 or an upper groove wall 523a of an inclined groove connected to the slide groove 522.
[0068] Furthermore, the center lock 5 further includes a third elastic member 544, which is disposed between the handle 54 and the center rod 53 to provide an elastic force for rotating the handle 54 so that the locking protrusion 541 moves into the closed end 521b of the lock groove 521. In the process of the handle 54 moving upward relative to the slider 52, the handle 54 rotates, so that the third elastic member 544 is twisted and in a deformed state; when the locking protrusion enters the open end 521a of the lock groove 521, the third elastic member 544 is released, and its elastic reset force drives the handle 54 to rotate in the opposite direction, so that the locking protrusion enters the closed end 521b from the open end 521a of the lock groove 521. In the example shown in the accompanying drawings, the third elastic member 544 is a tension spring, the upper end of which is connected to the limit joint 531 of the center rod 53, and the lower end of which is connected to the lower cover 542 of the handle 54; after the handle 54 rotates, the tension spring is stretched and twisted. The number of the third elastic member 544 can be one or more. In some other embodiments, the third elastic member 544 may also be a torsion spring or a spring sheet, etc., which is not limited herein.
[0069] Combine the following Figures 1 to 14 The method for unfolding or folding the tent 100 of this embodiment will be described in detail.
[0070] Tent 100 Figure 1 The expanded state shown transforms to Figure 3In the folded state shown, the center lock 5 is initially in a locked state. At this time, the user enters the tent 100 and rotates the handle 54 to move the locking protrusion 541 to the open end 521a of the lock groove 521 (the upper end of the slide groove 522); then the handle 54 is pulled downward to move the locking protrusion 541 downward along the slide groove 522 (specifically, the groove wall extending up and down of the slide groove 522) to the limit groove 523; the handle 54 is rotated in the opposite direction or with the help of the elastic force of the third elastic member 544, the locking protrusion 541 enters the limit groove 523. The center lock 5 is in the groove 523 and is located below the upper groove wall 523a thereof. At this time, the center lock 5 is converted to the holding state, and a smaller second locking force is provided by the second elastic member 543 to keep the tent 100 in the unfolded state. The user can move outside the tent 100 at this time; then, the user rotates the outer push rod 2 downward, the inner push rod 1 and the outer push rod 2 flip downward, the slider 52 moves upward and completely disengages from the handle 54, the center lock 5 is converted to the unlocking state, the push rod units 201 are close to each other, the support legs 300 are close to each other, and the tent 100 is converted to the unfolded state. Figure 3 Shown in folded state.
[0071] Tent 100 Figure 3 The folded state shown transforms to Figure 1 When the tent 100 is in the unfolded state, the center lock 5 is initially in the unlocked state. At this time, under the reset of the third elastic member 544, the locking protrusion 541 is opposite to the guiding inclined surface 524 on the slider 52, that is, it is located directly below the notch or channel at the bottom of the slider 52; the user pulls the outer push rod 2 upward outside the tent 100, and the outer end of the inner push rod 1 moves upward accordingly, the first elastic member 4 is released, and its elastic force is sufficient to overcome the dead weight of the rod, and then pushes the slider 52 away from the top cap 51, and the inclined rod 3 flips over to open each push rod unit 201; during the movement of the slider 52, the slider 52 and the handle 54 gradually approach each other, the locking protrusion 541 contacts the guiding inclined surface 524 and enters the open end 521a of the locking groove 521 under the guidance, and then automatically moves to the closed end 521b of the locking groove 521 under the elastic reset force of the third elastic member 544, to achieve complete locking, and the center lock 5 is automatically converted to the locked state, locking the tent 100 in the unfolded state.
[0072] The above tent 100 has the following advantages: during the opening of the tent 100, the user can operate outside the tent 100, avoiding entering the tent 100 to operate when the tent 100 is not fully opened, and the tent 100 can be automatically locked after opening; during the folding of the tent 100, after the user unlocks the center lock 5, the center lock 5 is in a holding state, and the tent 100 is maintained in an unfolded state so that the user can move outside the tent 100, and then operate outside the tent 100 to completely fold the tent 100, and the center lock 5 automatically changes from the holding state to the unlocking state. During the unfolding or folding of the tent 100, the user can avoid bending over to enter and exit the tent 100 when the tent is not fully and stably opened, which is convenient and safe to use, and provides a good experience. Example 2
[0073] Reference Fig.14 and Fig.15 As shown, this embodiment provides a tent 100 having an unfolded state and a folded state. Figures 1 to 3 As shown, the tent 100 also includes a top frame 200 and a plurality of supporting legs 300 supporting the top frame 200. The structures of the top frame 200 and the supporting legs 300 are the same as those of the tent 100 in Example 1. The internal space 400 of the tent 100 is defined by the top frame 200 and the supporting legs 300, and the space directly below the top frame 200 is the internal space 400 of the tent 100. The top frame 200 includes a plurality of foldable top rod units 201, and the plurality of top rod units 201 are connected to a center lock 5 located at the central top of the tent 100; the number of the top rod units 201 corresponds to the number of the supporting legs 300, and the outer end of each top rod unit 201 is connected to the upper part of a corresponding supporting leg 300. The top frame 200 also includes a plurality of external telescopic units 202, and an external telescopic unit 202 is connected to the upper part of every two adjacent supporting legs 300. The outer telescopic unit 202 can be folded and unfolded laterally, so that the support legs 300 are moved away from each other during the unfolding process, and the support legs 300 are moved closer to each other during the folding process. For example, the outer telescopic unit 202 is composed of a plurality of cross-shaped connecting rod assemblies hinged in sequence, and each cross-shaped connecting rod assembly includes two connecting rods 301 hinged to each other at the middle. In the cross-shaped connecting rod assembly connected to the support leg 300, one end of the upper connecting rod 301 is hinged to the upper end of the support leg 300, and one end of the lower connecting rod 301 is hinged to the sliding sleeve 302 on the support leg 300; when folding or unfolding, the sliding sleeve 302 can slide up and down on the support leg 300, and the outer telescopic unit 202 is relatively unfolded or folded.
[0074] Each push rod unit 201 includes an inner push rod 1 and an outer push rod 2 that can be turned relative to each other. The inner push rod 1 of each push rod unit 201 is rotatably connected through a center lock 5, and the outer end of the outer push rod 2 is hinged to the upper end of the support leg 300. In the embodiment shown in the drawings, the outer end of the inner push rod 1 and the inner end of the outer push rod 2 of each push rod unit 201 are directly pivoted to each other, the inner end of the inner push rod 1 is pivoted to the center lock 5, and the outer end of the outer push rod 2 is pivoted to the upper end of the support leg 300.
[0075] Combination Figures 16 to 23 As shown, the center lock 5 includes a top cap 51 and a slider 52 that moves up and down relative to the top cap 51. The top cap 51 is located above the slider 52, and the inner top rod 1 of each top rod unit 201 is rotatably connected to the top cap 51. Each top rod unit 201 also includes an inclined rod 3, the outer end of the inclined rod 3 is rotatably connected to the inner top rod 1, the inner end of each inclined rod 3 is rotatably connected to the slider 52, and the first elastic member 4 is connected to the slider 52. In the example shown in the accompanying drawings, the first elastic member 4 is arranged between the top cap 51 and the slider 52. When the tent 100 is in the unfolded state, the top cap 51 and the slider 52 have a first spacing, and the first elastic member 4 is in the original state, that is, no deformation occurs; when the tent 100 is in the folded state, the top cap 51 and the slider 52 have a second spacing, the first elastic member 4 is in a compressed state, and the first spacing is greater than the second spacing.
[0076] The opening drive member of the tent 100 is arranged on the center lock 5, specifically on the center rod 53 of the center lock 5. The center rod 53 and the top cap 51 are fixedly connected or integrated, and the center rod 53 extends vertically downward from the top cap 51. The slider 52 is slidably arranged on the center rod 53. The first elastic member 4 is a compression spring sleeved on the center rod 53, with its upper end on the top cap 51 and the lower end against the slider 52. When the tent 100 is folded, the slider 52 moves upward, that is, approaches the top cap 51, the distance between the two becomes shorter, and the compression spring is compressed. When the tent 100 is unfolded, the user rotates the outer top rod 2 until the elastic reset force of the compression spring is sufficient to overcome the constraint of the deadweight of the rod, and the compression spring pushes the slider 52 to move away from the top cap 51, and the distance between the two becomes larger, so that the inner end of the inner top rod 1 moves upward relative to the slider 52, and the inner top rod 1 flips upward to open.
[0077] When the tent 100 is converted from the unfolded state to the folded state, the center lock 5 is unlocked and placed in a holding state, and then the outer top rods 2 are operated or the driving member is opened outside the internal space 400 to convert the center lock 5 into an unlocked state, and the top rod units 201 are brought close to each other. Specifically, when the tent 100 is in the unfolded state, the center lock 5 is in a locked state. When the tent 100 is in the folded state, the center lock 5 is in an unlocked state. During the folding process of the tent 100, the center lock 5 also has a holding state between the locked state and the unlocked state. In this holding state, the tent 100 can still be maintained in the unfolded state, but a small force can be applied to the poles of the tent 100 to make the tent 100 fold under its own weight (for example, shaking or turning one of the outer top rods 2), and the center lock 5 is converted into an unlocked state.
[0078] The center lock 5 further includes a locking member, which is movably disposed on the center pole 53. When the center lock 5 is in a locked state, the locking member and the slider 52 are locked with each other to provide a first locking force that keeps the tent 100 in the deployed state. When the center lock 5 is in an unlocked state, the locking member and the slider 52 are disengaged. When the center lock 5 is in a holding state, the locking member and the slider 52 are in contact or locked with each other to provide a second locking force that is less than the first locking force, so that the tent 100 is maintained in the deployed state, and the user is allowed to disengage the locking member from the slider 52 when operating the outer top pole 2 outside the internal space 400, so that the center lock 5 is converted from the holding state to the unlocked state.
[0079] The center lock 5 also includes a lock seat 532 disposed on the center rod 53 and located below the slider 52. The above-mentioned locking member includes a rotating lock buckle 55 connected to the lock seat 532 or the center rod 53 through a pivot 550. The rotating lock buckle 55 has a first lock hook 551 and a second lock hook 552. The first lock hook 551 and the second lock hook 552 are respectively located on opposite sides of the pivot 550, forming a structure similar to a lever or a seesaw. The axis of the pivot 550 extends horizontally, and the first lock hook 551 and the second lock hook 552 are respectively located on opposite sides of the center rod 53. When the center lock 5 is in a locked state, the first lock hook 551 and the slider 52 are locked with each other and have a first locking surface 551a that contacts and cooperates with each other. At this time, there is a first angle between the first locking surface 551a and the horizontal plane. When the center lock 5 is in the holding state, the first lock hook 551 is separated from the slider 52, and the second lock hook 552 and the unlocking lock buckle 56 provided on the slider 52 are locked with each other and have a second locking surface 552a in contact and fit. At this time, the second locking surface 552a has a second angle with the horizontal. Fig.23 As shown, the second angle is greater than the first angle and less than 90 degrees. Furthermore, the first angle is 0-10 degrees, and the second angle is 45-85 degrees. The smaller the angle is, the greater the locking force between the slider 52 and the unlocking lock 56 is. The second angle is closer to 90 degrees, and the second lock hook 552 is easier to disengage from the unlocking lock 56.
[0080] The rotating lock buckle 55 is an integral part, pivotally connected to the lock seat 532. A first locking hole 525 is provided on the outer surface of the slider 52, which is recessed inwards. In the locked state, the first locking hook 551 is inserted into the first locking hole 525, and the first locking surface 551a of the first locking hook 551 and the bottom groove wall of the first locking hole 525 abut against each other. The first locking surface 551a is arranged downward and is approximately horizontal, so as to obtain a larger first locking force.
[0081] The top of the first lock hook 551 also has a top inclined surface 551b facing inward, and the bottom of the slider 52 has a bottom inclined surface 526 that matches each other. When the center lock 5 is in the unlocked state, the top inclined surface 551b of the first lock hook 551 is located directly below a bottom inclined surface 526 of the slider 52. Further, the center lock 5 also includes a fourth elastic member 57, which is arranged between the unlocking lock buckle 56 and the lock seat 532 or the center rod 53, so as to keep the rotating lock buckle 55 in the initial position when the center lock 5 is in the unlocked state. In the initial position, the top inclined surface 551b of the first lock hook 551 is located directly below a bottom inclined surface 526 of the slider 52, so that the first lock hook 551 is pushed outward when the top inclined surface 551b and the bottom inclined surface 526 slide relative to each other, and the fourth elastic member 57 is deformed at this time; until the first locking surface 551a of the first lock hook 551 is located at a position substantially equal to the first lock hole 525, the fourth elastic member 57 is released, and its elastic force drives the first lock hook 551 to move inward so as to be inserted into the first lock hole 525 to achieve locking. In the example shown in the drawings, the fourth elastic member 57 is a torsion spring; in some other embodiments, the fourth elastic member 57 can also be a compression spring, a tension spring or other forms of springs, which are not limited herein.
[0082] The unlocking lock catch 56 can be telescopically arranged in the slider 52. Specifically, a lock catch cover 562 is arranged on the slider 52, and a cavity is formed between the lock catch cover 562 and the slider 52. The unlocking lock catch 56 is inserted in the cavity, and an unlocking spring 57 is arranged between the unlocking lock catch 56 and the inner wall of the cavity for making the lower end of the unlocking lock catch 56 extend out of the cavity. A second lock hole 561 is recessed outwardly at the lower part of the unlocking lock catch 56, and the second lock hole 561 is opposite to the outer surface of the center rod 53. In the holding state, the second lock hook 552 is inserted into the second lock hole 561. The second locking surface 552a of the second lock hook 552 is arranged outward and downward, and it contacts the inclined bottom wall of the second lock hole 561 to provide a smaller second locking force. Under the action of a smaller external force, the second locking surface 552a will be separated from the second lock hole 561, and the second lock hook 552 and the unlocking lock catch 56 will be separated from each other, and the unlocking is achieved.
[0083] Combine the following Figures 15 to 23The method for unfolding or folding the tent 100 of this embodiment will be described in detail.
[0084] Tent 100 Fig.15 When the unfolded state shown is converted to the folded state, the center lock 5 is initially in the locked state. At this time, the user enters the tent 100 and rotates the rotary lock buckle 55 to rotate the first lock hook 551 outward to disengage from the slider 52 (the first lock hole 525). At the same time, the second lock hook 552 is inserted into the second lock hole 561 of the unlocking lock buckle 56. The center lock 5 is converted to the holding state. A smaller second locking force is provided by the second locking surface (which is an inclined surface) of the second lock buckle, so that the tent 100 is maintained in the unfolded state. The user can move outside the tent 100 at this time; then, the user rotates the outer top rod 2 downward, the inner top rod 1 and the outer top rod 2 flip downward, the slider 52 moves upward, and under the action of the inclined second locking surface, the second lock buckle disengages from the second lock hole 561, the center lock 5 is converted to the unlocked state, the top rod units 201 are close to each other, the supporting legs 300 are close to each other, and the tent 100 is converted to the folded state.
[0085] The tent 100 is transformed from the folded state to Fig.15 In the unfolded state shown, the center lock 5 is initially in the unlocked state. At this time, under the reset of the fourth elastic member 57, the first lock hook 551 is located directly below the slider 52, and the top inclined surface 551b of the first lock hook 551 is opposite to the bottom inclined surface 526 of the slider 52; the user pulls the outer push rod 2 upward outside the tent 100, and the outer end of the inner push rod 1 moves upward accordingly, the first elastic member 4 is released, and its elastic force is sufficient to overcome the dead weight of the rod, and then pushes the slider 52 away from the top cap 51, and the inclined rod 3 flips over, so that each push rod unit 201 is opened; during the movement of the slider 52, the slider 52 and the lock seat 532 / The rotating lock buckle 55 gradually approaches, the bottom inclined surface 526 of the slider 52 contacts the top inclined surface 551b of the first lock hook 551, pushing the first lock hook 551 outward, and the fourth elastic member 57 is deformed; when the first locking surface 551a is flush with the first lock hole 525, the fourth elastic member 57 is released, and its elastic force pushes the first lock hook 551 inward to insert into the first lock hole 525, and the first locking surface 551a and the bottom wall of the first lock hole 525 contact each other to achieve complete locking, and the center lock 5 is automatically converted to a locked state, locking the tent 100 in the expanded state.
[0086] The above tent 100 has the following advantages: during the opening of the tent 100, the user can operate outside the tent 100, avoiding entering the tent 100 to operate when the tent 100 is not fully opened, and the tent 100 can be automatically locked after opening; during the folding of the tent 100, after the user unlocks the center lock 5, the center lock 5 is in a holding state, and the tent 100 is maintained in an unfolded state so that the user can move outside the tent 100, and then operate outside the tent 100 to completely fold the tent 100, and the center lock 5 automatically changes from the holding state to the unlocking state. During the unfolding or folding of the tent 100, the user can avoid bending over to enter and exit the tent 100 when the tent is not fully and stably opened, which is convenient and safe to use, and provides a good experience.
