[0002] In the installation of the wall cupboard, usually need to use the support device to support the wall cupboard, to facilitate the installation of the wall cupboard.

[0003] Such as the utility model patent authorized announcement number for: CN220571819U, discloses a kind of height-adjustable support device, including bottom support, top support, telescopic mechanism, wherein, telescopic mechanism includes first lifting assembly and second lifting assembly, second lifting assembly includes first lifting pipe, second lifting pipe and locking screw.Pause when needing to lift support device, can loosen locking screw, and second lifting pipe can be quickly raised or lowered to adjust height, after adjusting the height position of second lifting pipe, locking screw is tightened again, and the height position of second lifting pipe can be locked, to realize the quick adjustment operation of second lifting assembly.

[0004] But the support device still has the deficiency, that is, in the operation of adjusting second lifting pipe, it needs to be locked and unlocked by rotating locking screw, which is troublesome and time-consuming and laborious. UTILITY MODEL CONTENTS

[0005] In view of the above deficiencies in the prior art, the utility model aims to provide a telescopic support rod of fixed level adjustment which is convenient to lock and unlock.

[0006] In order to achieve the above purpose, the utility model takes the technical scheme that a telescopic support rod of fixed level adjustment, including first branch pipe, second branch pipe which is arranged in the first branch pipe and can slide axially relative to the first branch pipe, and locking mechanism for limiting the sliding of the second branch pipe, the locking mechanism includes base arranged on the outer side of the first branch pipe, lock catch movably connected to the base, and elastic member arranged on the base, a lock slot is formed in the outer side wall of the second branch pipe, when the second branch pipe is slid to the position of the lock slot and the lock catch, the elastic member will push the lock catch and the lock slot to engage.

[0007] In the above scheme, the lock catch is movably connected to the base, when the second branch pipe is slid to the position of the lock slot and the lock catch, the elastic member will automatically push the lock catch and the lock slot to engage by its elastic force, so that the second branch pipe cannot slide relative to the first branch pipe;And the lock catch is disengaged from the lock slot, so that the locking of the second branch pipe is released, and the second branch pipe can continue to slide to adjust the height, so that the second branch pipe can be locked and unlocked very conveniently, and the work efficiency is improved.

[0008] Further, the above-mentioned lock catch comprises a bottom plate rotatably connected to the base, a clamping block and a push piece arranged at the end of the bottom plate, and the end of the clamping block away from the bottom plate is a locking end. When the second branch pipe is slid to the position where the locking end of the clamping block is aligned with the locking slot, the elastic member will push the bottom plate to rotate and drive the locking end of the clamping block to engage with the locking slot. At this time, the locking slot of the second branch pipe is blocked by the locking end of the clamping block and cannot be slid, thereby locking the second branch pipe. Pushing the push piece can drive the bottom plate to rotate and make the locking end of the clamping block disengage from the locking slot, thereby releasing the locking of the second branch pipe.

[0009] Further, the above-mentioned locking mechanism further comprises a handle rotatably connected to the outside of the base. Rotating the handle can push the push piece to rotate and drive the locking end of the clamping block to disengage from the locking slot. This scheme can realize the unlocking operation by operating the handle to drive the push piece to rotate, and the operation will be more convenient.

[0010] Further, the end surface of the locking end of the clamping block is a flat surface, which can make the locking end of the clamping block engage with the upper side wall of the locking slot more stably, thereby ensuring the stability of the locking of the second branch pipe. The side surface of the clamping block corresponding to the lower side wall of the locking slot is an arc surface. When the locking end of the clamping block engages with the locking slot, if the second branch pipe slides in the elongation direction relative to the first branch pipe, the outer edge of the lower side wall of the locking slot will slide relative to the arc surface on the lower side of the clamping block, thereby lifting the clamping block to disengage from the locking slot. In other words, the arc surface on the lower side of the clamping block cannot effectively block the lower side wall of the locking slot, so that the locking end of the clamping block cannot block the second branch pipe from sliding in the elongation direction relative to the first branch pipe when it is engaged with the locking slot, but only can block the second branch pipe from sliding in the retraction direction relative to the first branch pipe. In other words, when the second branch pipe needs to slide in the elongation direction relative to the first branch pipe, it only needs to be pulled directly in the elongation direction, without the need to operate the locking mechanism, so that the adjustment operation is more convenient.

[0011] Further, the base is fixedly sleeved on the outside of the upper end of the first branch pipe, the locking end of the clamping block is located above the first branch pipe, and a positioning protrusion is arranged on the inside of the base corresponding to the position of the upper end of the first branch pipe. The upper end surface of the first branch pipe abuts against the lower side of the positioning protrusion, which can prevent the base from moving downward along the first branch pipe and improve the installation stability of the base. Further, a limiting protrusion is arranged on the outside of the lower end of the second branch pipe, and the upper side of the limiting protrusion can abut against the lower side of the positioning protrusion, which can prevent the second branch pipe from sliding out of the base and ensure the installation stability of the second branch pipe.

[0012] Further, the base is oppositely provided with two side plates, a first connecting shaft is arranged between the two side plates, two connecting ears are oppositely arranged on the side surface of the bottom plate, the two connecting ears are sleeved on the first connecting shaft outside the position corresponding to the two side plates, the elastic member is a torsion spring sleeved between the first connecting shaft outside the position corresponding to the two connecting ears, one leg of the torsion spring abuts against the bottom plate, and the other leg abuts against the base. Under the action of no external force, the torsion spring will push the bottom plate to rotate inwardly by the elastic force of the torsion spring, so that when the second branch pipe slides to the position where the locking groove is aligned with the locking end of the clamping block, the torsion spring will push the bottom plate to rotate to drive the locking end of the clamping block to be buckled with the locking groove, so as to realize the automatic locking function of the second branch pipe.

[0013] In order to realize the structure and function that the rotation of the handle can push the push piece to rotate to be unlocked, the handle is rotatably connected to the position between the two side plates through the second connecting shaft, one end of the handle close to the push piece is provided with a pry block. In use, the pry block can push the push piece to drive the bottom plate to rotate outwardly to drive the locking end of the clamping block to be separated from the locking groove by pushing the tail end of the handle to rotate upwardly, so that the unlocking operation is very convenient.

[0014] Further, the locking groove is provided with a plurality of locking grooves, and the plurality of locking grooves are uniformly arranged along the length direction of the second branch pipe. In this way, the locking end of the clamping block can be buckled with the locking grooves at different positions, so as to lock the second branch pipe at a plurality of different height positions.

[0015] Further, the first branch pipe is provided with a base at the lower end, and the second branch pipe is provided with a support seat at the upper end. In this way, the support stability of the support rod can be improved. The lower side of the support seat is oppositely provided with two clamping plates, the upper end of the second branch pipe is arranged between the two clamping plates, and a screw is threadedly connected with a nut by penetrating the two clamping plates and the second branch pipe. In this way, the support seat can rotate around the screw to adjust the angular position of the support seat, so as to realize the adhesion to the horizontal or inclined bottom surface of the cabinet, and ensure the stability of supporting the cabinet.

[0016] Further, the lower side of the base and the upper side of the support seat are respectively provided with soft pads. The soft pads can increase the friction with the bottom surface of the cabinet, so that the support stability of the cabinet is better, and the cabinet surface is not easily damaged by the contact of the soft pads with the cabinet.

[0017] The level-adjustable telescopic supporting rod of the utility model solves the problem of troublesome locking and unlocking operation of the existing supporting device, compared with the existing supporting device which is locked and unlocked through locking screw, the supporting rod of the utility model only needs to push the handle to drive the locking end of the clamping block to separate from the locking groove, so that the locking can be released, thereby the second branch pipe can be operated to slide along the retracting direction relative to the first branch pipe to reduce the length of the supporting rod, if the length of the supporting rod needs to be increased, the second branch pipe needs to slide along the lengthening direction relative to the first branch pipe, after the second branch pipe is slid to the position that the locking groove is aligned with the locking end of the clamping block, the torsional spring will automatically push the locking end of the clamping block to be buckled with the locking groove, so that the second branch pipe can be locked, the second branch pipe is prevented from retracting, the operation is very convenient, and the adjustment operation efficiency is improved.

[0027] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0028] Example 1

[0029] like Figure 1 As shown, this embodiment provides a telescopic support rod with adjustable levels, including a first branch pipe 1, a second branch pipe 2 that passes through the first branch pipe 1 and can slide axially relative to the first branch pipe 1, and a locking mechanism 5 for restricting the sliding of the second branch pipe 2. In the unlocked state of the locking mechanism 5, as shown... Figure 2 As shown, pushing the second branch pipe 2 downwards allows it to slide relative to the first branch pipe 1 to the retracted state, and as... Figure 3 As shown, pushing the second branch pipe 2 upwards allows it to slide relative to the first branch pipe 1 to an extended state. The aforementioned locking mechanism 5 includes a base 51 located on the outside of the first branch pipe 1, a latch 52 movably connected to the base 51, and an elastic member 54 located on the base 51. A locking groove 21 is provided on the outer wall of the second branch pipe 2. When the second branch pipe 2 is slid until the locking groove 21 and the latch 52 are aligned, the elastic member 54 will push the latch 52 to engage with the locking groove 21.

[0030] Specifically, such as Figures 4-6 As shown, the aforementioned latch 52 includes a base plate 521 rotatably connected to the base 51, a locking block 522 and a lever 523 located at the end of the base plate 521. The end of the locking block 522 away from the base plate 521 is the locking end 5221. When the second branch tube 2 is slid until the locking groove 21 is aligned with the locking end 5221 of the locking block 522, the elastic member 54 will push the base plate 521 to rotate, thereby engaging the locking end 5221 of the locking block 522 with the locking groove 21. At this time, the locking groove 21 of the second branch tube 2 cannot slide due to the blocking of the locking end 522 of the locking block 522, thus locking the second branch tube 2. By moving the lever 523 to rotate the base plate 521, the locking end 5221 of the locking block 522 will disengage from the locking groove 21, thus releasing the lock on the second branch tube 2. At this time, the second branch tube 2 can continue to slide relative to the first branch tube 1.

[0031] likeFigure 3 As shown, the lock slot 21 is provided with several lock slots 21, and the several lock slots 21 are uniformly arranged along the length direction of the second branch pipe 2, so that the locking end 5221 of the clamping block 522 can be buckled with the lock slot 21 at different positions, so as to lock the second branch pipe 2 at different height positions.

[0032] When the height of the telescopic support rod of the embodiment is needed to be adjusted, the locking end 5221 of the clamping block 522 can be driven to be separated from the lock slot 21 by rotating the push piece 523, so as to release the locking of the second branch pipe 2, and then the second branch pipe 2 is slid to the position where the locking end 5221 of the clamping block 522 is aligned with the lock slot 21 at the corresponding height, and then the push piece 523 is released, at this time, the elastic member 54 will automatically push the bottom plate 521 to rotate by the elastic force of itself, so that the locking end 5221 of the clamping block 522 is buckled with the lock slot 21, so as to lock the second branch pipe 2 and cannot be slid, so as to complete the height adjustment operation of the support rod.

[0033] The telescopic support rod of the embodiment solves the problem of troublesome locking and unlocking operation of the existing support device, compared with the existing support device which is locked and unlocked by the locking screw, the telescopic support rod of the embodiment is locked and unlocked by the buckling and separation of the clamping block 522 and the lock slot 21, which is very convenient to operate and improves the adjustment operation efficiency.

[0034] Embodiment two

[0035] The embodiment is a further improvement on the basis of the telescopic support rod of the embodiment one, and the improvement is that, as shown in Figure 4 , 5 The locking mechanism 5 further includes a handle 55 which is rotatably connected to the outside of the base 51, and rotating the handle 55 can drive the push piece 523 to rotate and drive the locking end 5221 of the clamping block 522 to separate from the lock slot 21, so that the handle 55 can be operated to drive the push piece 523 to rotate and realize the unlocking operation, which is more convenient to operate.

[0036] As shown in Figure 4As shown, the base is provided with two side plates 512 on the outside, a first connecting shaft 513 is arranged between the two side plates 512, and two connecting ears 5211 are arranged on the side of the bottom plate 521, the two connecting ears 5211 are sleeved on the outside of the first connecting shaft 513 corresponding to the position between the two side plates 512, and the elastic member 54 is a torsion spring sleeved on the outside of the first connecting shaft 513 corresponding to the position between the two connecting ears 5211. One leg of the torsion spring abuts against the bottom plate 521, and the other leg abuts against the base 51. Under the action of no external force, the bottom plate 521 is pushed inward by the elastic force of the torsion spring, so that when the second branch pipe 2 slides to the position where the locking groove 21 is aligned with the locking end 5221 of the clamping block 522, the bottom plate 521 is automatically pushed inward by the torsion spring to drive the locking end 5221 of the clamping block 522 to be buckled with the locking groove 21, thereby realizing the automatic locking function of the second branch pipe 2.

[0037] As shown in Figure 4 , 7 In order to realize the structure and function that the rotation of the handle 55 can push the push piece 523 to rotate and unlock, the handle 55 is rotatably connected to the position between the two side plates 512 through a second connecting shaft 514, and one end of the handle 55 close to the push piece 523 is provided with a pry block 551. In use, the pry block 551 can push the push piece 523 to drive the bottom plate 521 to rotate outward and drive the locking end 5221 of the clamping block 522 to be separated from the locking groove 21 by only pushing the tail end of the handle 55 to rotate upward, so that the unlocking operation is very convenient.

[0038] As a modified scheme of the embodiment, as shown in Figure 6 The upper end surface of the locking end 5221 of the clamping block 522 is a flat surface, and the upper side wall of the locking groove 21 is also a flat surface. In the buckled state of the locking end 5221 of the clamping block 522 and the locking groove 21, the upper end surface of the locking end 5221 abuts against the upper side wall of the locking groove 21, so that the buckling of the locking end 5221 of the clamping block 522 and the upper side wall of the locking groove 21 is more stable, thereby ensuring the locking stability of the second branch pipe 2. In addition, the side surface of the clamping block 522 corresponding to the lower side wall of the locking groove 21 is an arc surface. When the locking end 5221 of the clamping block 522 is buckled with the locking groove 21, if the second branch pipe 2 slides in the elongation direction relative to the first branch pipe 1, the outer edge of the lower side wall of the locking groove 21 will slide relative to the arc surface on the lower side of the clamping block 522, thereby lifting the clamping block 522 to be separated from the locking groove 21. It is equivalent that the arc surface on the lower side of the clamping block 522 cannot effectively block the lower side wall of the locking groove 21, so that the locking end 5221 of the clamping block 522 cannot block the second branch pipe 2 from sliding in the elongation direction relative to the first branch pipe 1 in the buckled state with the locking groove 21, but can only block the second branch pipe 2 from sliding in the retraction direction relative to the first branch pipe 1. It is equivalent that when the second branch pipe 2 needs to slide in the elongation direction relative to the first branch pipe 1, it only needs to be directly pulled in the elongation direction, without the need to operate the locking mechanism, so that the adjustment operation is more convenient.

[0039] Example 3

[0040] This embodiment is a further improvement on the graded adjustment telescopic support rod structure of Embodiment 2. The improvement lies in that, as... Figure 6 As shown, the base 51 is fixedly fitted onto the outer side of the upper end of the first branch pipe 1. The locking end 5221 of the locking block 522 is located above the first branch pipe 1. A positioning protrusion 515 is provided on the inner side of the base 51 corresponding to the upper end of the first branch pipe 1. The upper surface of the first branch pipe 1 abuts against the lower side of the positioning protrusion 515. This prevents the base 51 from moving downward along the first branch pipe 1, improving the installation stability of the base 51. Furthermore, a limiting protrusion 22 is provided on the outer side of the lower end of the second branch pipe 2. The upper side of the limiting protrusion 22 abuts against the lower side of the positioning protrusion 515. This prevents the second branch pipe 2 from sliding upward out of the base 51, ensuring the installation stability of the second branch pipe 2.

[0041] like Figure 1 , 3 As shown, the lower end of the first branch pipe 1 is provided with a base 3, and the upper end of the second branch pipe 2 is provided with a support seat 4, which can improve the support stability of the support rod. In addition, the lower side of the base 3 and the upper side of the support seat 4 are respectively provided with soft pads 31. The soft pads 31 can increase the friction with the bottom surface of the wall cabinet, thus providing better support stability for the wall cabinet. Furthermore, the contact between the soft pads 31 and the wall cabinet makes it less likely to damage the surface of the wall cabinet.

[0042] When using the adjustable telescopic support rod of this utility model, first place the support rod under the wall cabinet, while the base 3 supports the ground or tabletop under the wall cabinet. Then adjust the height of the second branch pipe 2 so that the support seat 4 supports the wall cabinet. This completes the support operation of the support rod, allowing the support rod to support the wall cabinet and facilitating the installation of the wall cabinet.

[0043] As an improvement to this embodiment, such as Figure 1 As shown, the support base 4 has two clamping plates 41 facing each other on its lower side. The upper end of the second branch pipe 2 is positioned between the two clamping plates 41. A screw 61 passes through the two clamping plates 41 and the second branch pipe 2 and is threadedly connected to a nut 62, allowing the support base 4 to rotate around the screw 61 to adjust its angle. This ensures that the support base 4 can fit snugly against the horizontal or inclined bottom surface of the wall cabinet, guaranteeing its stability. In use, the nut 62 can be loosened, allowing the support base 4 to rotate around the screw 61 to adjust its angle. Tightening the nut 62 will lock the support base 4 against the two clamping plates 41, preventing it from rotating around the screw 61.

[0044] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and also impossible to exhaust all the implementation modes. Any modification, equivalent replacement and improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application claims.
