Description

Technical Field

[0001] This utility model relates to the field of furniture, and in particular to a bed connection structure. Background Technology

[0002] Most household beds consist of a bed frame and tubular bed legs that connect to the frame and support it on the ground. The tubular bed legs are usually made of metal and extend beyond the bottom of the bed frame to keep the bed frame at a reasonable height. However, this design also makes the bed take up too much volume and space during transportation. Therefore, many existing beds have designed the tubular bed legs to be shorter and are equipped with extension legs that can be detachably connected to the tubular bed legs. This saves on transportation costs while ensuring that the bed frame is at a reasonable height when in use.

[0003] like Figure 10a As shown, the existing raised bed leg 3 has a slot 3a with an opening at the top. The shape and size of the slot 3a match the tubular bed leg 2. The portion of the tubular bed leg 2 extending beyond the lower end of the bed frame 1 forms an insert section. When assembling the raised bed leg 3 with the tubular bed leg 2, the insert section is inserted into the slot 3a and then fixed to the raised bed leg 3 with screws. However, this design relies on the insert section matching the slot 3a on the raised bed leg 3. Figure 10b As shown, when the tubular bed leg 2 is designed to be shorter to further save transportation space, so that it is basically flush with the lower end of the bed frame 1, the insertion section no longer exists. At this time, the tubular bed leg 2 is close to the bed frame 1, and it is difficult to insert it with the slot 3a. Therefore, the application range of this connection structure is limited. Summary of the Invention

[0004] This utility model provides a bed connection structure, in which an insertion boss matching the inner contour of the tubular bed leg is provided at the top of the raised bed leg. The insertion boss can be inserted into the tubular bed leg. The support end face supports the top of the tubular bed leg, so that the connection between the raised bed leg and the tubular bed leg is no longer affected by the length of the tubular bed leg. While not affecting the normal use of the bed, it further reduces the volume and cost of the bed frame during transportation.

[0005] The technical solution of this utility model is implemented as follows: A bed frame connection structure includes a bed frame and tubular bed legs connected to the bed frame with open lower ends. The tubular bed legs have raised feet at their lower ends. The top of the raised feet has an insert boss that matches the inner contour of the tubular bed legs. The junction between the insert boss and the raised feet forms a supporting end face. The insert boss is inserted into the tubular bed legs from bottom to top, so that the supporting end face abuts against the lower end of the tubular bed legs.

[0006] Preferably, a locking structure is provided between the insert boss and the tubular bed leg, which can prevent the tubular bed leg from disengaging upward from the insert boss.

[0007] Preferably, the locking structure includes a screw hole provided on the insertion boss and a through hole provided on the tubular bed leg, with the screw passing through the through hole and locked into the screw hole.

[0008] Preferably, the insert boss is a hollow tubular structure, and a connecting seat is integrally formed on the inner wall of the tubular structure, with screw holes provided on the connecting seat.

[0009] Preferably, the locking structure includes a recessed hole on the side of the insertion boss, a retractable locking member inside the recessed hole, and a corresponding through hole on the tubular bed leg, the locking member extending out elastically and locking into the through hole.

[0010] Preferably, the tubular bed legs extend downwards beyond the lower end of the bed frame to form an overhanging section, and the top of the raised bed legs is provided with an annular stop that extends above the support end face. The annular stop and the insert boss form an enclosing space, and the overhanging section is located within the enclosing space; making the appearance of the bed more concise and beautiful.

[0011] Preferably, the raised bed legs include a base and a lifting seat that slides longitudinally onto the base. The lifting seat can slide longitudinally and be held in a predetermined position. An insert boss is provided at the top of the lifting seat to facilitate the adjustment of the bed frame height by moving the lifting seat up and down.

[0012] Preferably, one of the base and the lifting seat has multiple position holes arranged longitudinally at intervals, and the other of the base and the lifting seat has a positioning hole. A locking pin is inserted into the positioning hole and the corresponding position hole at the same time to keep the lifting seat in a predetermined position.

[0013] Preferably, one of the base and the lifting seat has an internal threaded sleeve, and the other of the base and the lifting seat has an external threaded rod, which is threadedly connected to the internal threaded sleeve; rotating the external threaded rod or the internal threaded sleeve causes the lifting seat to move longitudinally and remain in a predetermined position.

[0014] Preferably, the side wall of the insert boss is provided with a protruding limiting part, and the tubular bed is provided with a limiting groove with a lower opening that matches the limiting part. The limiting part is inserted and fitted into the limiting groove; this prevents the tubular bed leg from shaking after it is connected to the insert boss, and makes the fit between the insert boss and the tubular bed leg more stable.

[0015] Preferably, the length of the insert boss ranges from 15mm to 70mm.

[0016] The beneficial effects of this utility model, which adopts the above technical solution, are as follows: This invention features a protruding insertion boss at the top of the raised bed leg that matches the inner contour of the tubular bed leg. The junction of the insertion boss and the raised bed leg forms a supporting end face. To further save transportation space and cost, the lower end of the tubular bed leg can be flush with the lower end of the bed frame. The insertion boss can also be inserted into the tubular bed leg and support it using the supporting end face. This design cleverly utilizes the hollow structure of the tubular bed leg to insert the insertion boss. Regardless of whether the tubular bed leg extends beyond the lower end of the bed frame, it can be assembled with the raised bed leg. This expands the applicability of connecting the tubular bed leg and the raised bed leg and reduces the overall volume and cost of the bed during transportation.

[0017] A locking structure is provided between the insert boss and the tubular bed leg. After the insert boss is inserted into the tubular bed leg, the locking structure can prevent the tubular bed leg from detaching from the insert boss upwards, ensuring the connection stability of the heightened bed leg and the tubular bed leg after assembly.

[0018] When the lower end of the tubular bed leg still has a short section that extends beyond the lower end of the bed frame, the ring-shaped stop extending upwards from the top of the raised bed leg can cover it, preventing the extended section from being exposed between the raised bed leg and the bed frame, making the bed look more concise and beautiful.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0022] This utility model has several specific embodiments, and the specific implementation methods are as follows: Example 1: As Figure 1-7 As shown, this embodiment provides a bed connection structure, including a bed frame 1, tubular bed legs 2 connected to the bed frame 1 and open at the lower end, and raised bed legs 3 provided below the tubular bed legs 2; the bed frame 1 can be assembled from multiple wooden parts by screws, or from multiple metal parts by welding or screws; the bed assembled from the bed frame 1 and the tubular bed legs 2 can be the main bed of the bedroom, or a modular bed assembled with the side of the main bed; in this embodiment, the tubular bed legs 2 are fixedly connected to each corner of the bed frame 1, and the tubular bed legs 2 are usually rigid components made of iron or steel; the top of the raised bed legs 3 is provided with an insert boss 4 that matches the inner contour of the tubular bed legs 2, and the connection between the insert boss 4 and the top of the raised bed legs 3 is preferably integrally formed; Figure 2-3 As shown, a supporting end face 41 is formed at the junction of the inserting boss 4 and the raised bed leg 3. When the raised bed leg 3 is assembled with the tubular bed leg 2, the inserting boss 4 is inserted into the tubular bed leg 2 from bottom to top, so that the supporting end face 41 abuts against the lower end of the tubular bed leg 2. This allows the raised bed leg 3 to support the tubular bed leg 2 upwards. Regardless of whether the tubular bed leg 2 extends downwards beyond the lower end of the bed frame 1, it does not affect the insertion connection between the inserting boss 4 and it. On this basis, in order to further save transportation space and costs, the length of the portion of the tubular bed leg 2 extending beyond the lower end of the bed frame 1 can be reduced, or the lower end of the tubular bed leg 2 can be made flush with the lower end of the bed frame 1, further reducing the longitudinal space occupied by the bed and transportation costs. At the same time, as Figure 6As shown, when the lower end of the tubular bed leg 2 is flush with the lower end of the bed frame 1 and the extension bed leg 3 is not used, the lower end of the entire bed frame 1 is in direct contact with the ground. At this time, a mattress can be laid on the upper end of the bed frame 1, and the bed can be used as a tatami mat. Therefore, the shorter tubular bed leg 2 can also make the use of the bed more diversified.

[0023] Furthermore, in order to ensure the stability of the tubular bed leg 2 after assembly with the raised bed leg 3, a locking structure is provided between the insert boss 4 and the tubular bed leg 2. In this embodiment, the locking structure includes a screw hole 42 provided on the insert boss 4 and a through hole 21 provided on the tubular bed leg 2. The screw passes through the through hole 21 and is locked into the screw hole 42; thus preventing the tubular bed leg 2 from detaching upward from the insert boss 4.

[0024] Furthermore, the insert boss 4 can be a solid structure. A solid structure makes the threaded connection between the insert boss 4 and the tubular bed leg 2 more stable. However, a solid design consumes more material and will increase costs during mass production. Therefore, in this embodiment, the insert boss 4 is preferably a hollow tubular structure. At the same time, to ensure that the threaded connection between the tubular structure and the tubular bed leg 2 is also stable, a connecting seat 44 is integrally formed on the inner wall of the tubular structure, and a screw hole 42 is set on the connecting seat 44. This makes the threaded section of the screw hole 42 have a certain length, which saves costs without affecting the threaded connection strength between the insert boss 4 and the tubular bed leg 2.

[0025] Furthermore, if the tubular bed leg 2 extends downward beyond the lower end of the bed frame 1, forming an overhanging section 211, then when the inserting boss 4 is inserted into the tubular bed leg 2, the overhanging section 211 will be exposed between the top of the raised bed leg 3 and the lower end of the bed frame 1, which is not aesthetically pleasing. Therefore, in this embodiment, the top of the raised bed leg 3 is provided with an annular stop 43 that extends above the supporting end face 41. Figure 3 As shown, the annular stop 43 and the insert boss 4 form a retaining space, and the protruding section 211 is located within the retaining space; as Figure 4 As shown, in terms of appearance, the extended section 211 is blocked by the annular stop 43, making the bed's shape more concise and beautiful.

[0026] Furthermore, to facilitate adjusting the height between the bed frame 1 and the ground, the raised bed leg 3 in this embodiment is preferably a liftable bed leg, such as... Figure 5As shown, specifically, the raised bed leg 3 includes a base 31 and a lifting seat 32 slidably connected to the base 31 longitudinally. Both the base 31 and the lifting seat 32 extend vertically. The lifting seat 32 can slide longitudinally and remain in a predetermined position. An insert boss 4 is provided at the top of the lifting seat 32 to facilitate the adjustment of the height of the bed frame 1 by moving the lifting seat 32 up and down. Specifically, the base 31 is provided with a guide groove 311 that is open at the top and extends vertically, and the lifting seat 32 is slidably connected in the guide groove 311. To ensure that the lifting seat 32 can remain in the predetermined height position after adjustment, a positioning structure is provided between the lifting seat 32 and the base 31. The positioning structure includes... One of the base 31 and the lifting seat 32 has a plurality of position holes 51 arranged longitudinally at intervals, and the other of the base 31 and the lifting seat 32 has a positioning hole 5. In this embodiment, only the structure in which the position holes 51 are set on the base 5 and the positioning holes 51 are set on the lifting seat 32 is illustrated, wherein the position holes 51 pass through the base 31; when the lifting seat 32 is adjusted to a predetermined position, a locking pin is simultaneously inserted into the positioning hole 5 and the corresponding position hole 51 to keep the lifting seat 32 in the predetermined position; or, the positioning hole 5 can be replaced with a threaded hole and the locking pin can be replaced with a screw, so that the screw passes through the position hole 51 and locks into the threaded hole, which can also achieve the same positioning effect.

[0027] Furthermore, such as Figure 7 As shown, to make the fit between the insert boss 4 and the tubular bed leg 2 more stable, a protruding limiting part 45 is provided on the side wall of the insert boss 4, and the limiting part 45 is integrally formed with the insert boss 4; the number of limiting parts 45 can be single or multiple; the tubular bed leg 2 is provided with a limiting groove 22 that matches the limiting part 45, and the lower end of the limiting groove 22 is open to facilitate the insertion of the limiting part 45; when the insert boss 4 is inserted into the tubular bed leg 2, the limiting part 45 is inserted and fitted in the limiting groove 22 to prevent the tubular bed leg 2 from loosening or shaking after being connected to the insert boss 4; to make the entire bed connection structure more compact and stable, the limiting part 45 can also be integrally formed with the insert boss 4 and the annular stop part 43 at the same time to increase the structural strength of the annular stop part 43.

[0028] Furthermore, the insert boss 4 may extend beyond the upper end of the annular stop 43, but considering the appearance of the bed, the limiting part 45 in this embodiment is preferably located at the lower position of the insert boss 4 and within the enclosure space, so that the limiting part 45 is hidden within the enclosure space, which restricts the loosening of the tubular bed leg 2 without affecting the appearance of the bed.

[0029] Furthermore, the length of the insert boss 4 needs to be kept within a reasonable range. If the length of the insert boss 4 is too short, it will easily come out after being inserted into the tubular bed leg 2. If the length of the insert boss 4 is too long, although it can ensure that the insert boss 4 will not easily come out of the tubular bed leg 2 after being inserted, it will waste too much material. At the same time, if the tubular bed leg 2 and the bed frame 1 are connected by screws, the excessively long insert boss 4 is likely to interfere with the screws inside the tubular bed leg 2. Therefore, considering the above reasons, the length range of the insert boss 4 in this embodiment is preferably 15mm-70mm.

[0030] Example 2: Figure 8 As shown, the difference between this embodiment and the above embodiment is that a threaded structure is used between the base 31 and the lifting seat 32 to adjust the height of the bed frame 1 to a predetermined position. Specifically, one of the base 31 and the lifting seat 32 has an internal threaded sleeve, and the other of the base 31 and the lifting seat 32 has an external threaded rod, which is threadedly connected to the internal threaded sleeve. In this embodiment, only the structure in which the internal threaded sleeve is set on the base 5 and the external threaded rod is set on the lifting seat 32 is illustrated. Rotating the external threaded rod or the internal threaded sleeve causes the lifting seat 32 to move longitudinally. After adjustment, due to the self-locking property of the threaded connection structure, the lifting seat 32 can remain in the predetermined position. Compared with the multi-positioning structure in Embodiment 1, the threaded adjustment method in this embodiment allows the lifting seat 32 to stop at any position, adjusting the height of the bed frame 1 to the desired position.

[0031] Example 3: As Figure 9 As shown, the difference between this embodiment and the above embodiment is that the locking structure includes a recessed hole on the side of the insertion boss 4, and a retractable locking member 6 is provided in the recessed hole. Specifically, the locking member includes a hollow base, and a limiting ball and a compression spring are provided in the base. The compression spring acts on the limiting ball, so that its hemispherical surface extends out of the base. The tubular bed leg 2 is provided with a corresponding through hole 21. When the tubular bed leg 2 is assembled with the insertion boss 4, the limiting ball can be manually pressed first, so that the insertion boss 4 can be inserted into the tubular bed leg 2. At this time, the compression spring is in an elastic compression state. When the insertion boss 4 continues to be inserted and the limiting ball is aligned with the through hole 21, the compression spring resets and the limiting ball automatically pops out and locks into the through hole 21. This can also prevent the tubular bed leg 2 from coming off the insertion boss 4. On this basis, the limiting ball can also be replaced with a pin, which can also achieve the same locking effect.

[0032] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
