Description

Technical Field

[0001] This application relates to the technical field of fixture fasteners, and particularly to a hoop and a connecting rod using the hoop. Background Art

[0002] Most of the existing tables, chairs and furniture include legs and a supporting tabletop. The legs are usually composed of two telescopic support legs, and a corresponding partition is also arranged between the two telescopic support legs to play a role of a screen for blocking. When installing the partition, a corresponding connecting rod needs to be set for fixation.

[0003] In the related art, the connecting rod and the partition are fixed by screws, and both ends of the connecting rod are fixedly connected to the corresponding telescopic support legs by bolts respectively, so that there is good connection firmness between the connecting rod and the telescopic support legs.

[0004] In view of the above related art, when the telescopic support legs are telescopically adjusted, the relative positions of the partition and the connecting rod cannot be adjusted accordingly as needed, which is inconvenient to use. Utility Model Content

[0005] In order to facilitate the adjustment of the relative position between the connecting rod and the support leg as needed, this application provides a hoop.

[0006] The hoop provided by this application adopts the following technical solution:

[0007] A hoop includes:

[0008] A connection block is provided with a connection end portion and a mounting portion. The mounting portion is fixedly connected to the connecting rod, and an insertion slot is formed in the mounting portion.

[0009] A clamping piece is provided with a first insertion end and a second insertion end. When both the first insertion end and the second insertion end are inserted into the insertion slot, an enclosing hole is formed between the clamping piece and the connection block, and when the telescopic support leg passes through the enclosing hole, it is tightly clamped.

[0010] A locking screw is arranged on the connection block and forms a threaded connection. The locking screw has a tightened state and a loosened state. When in the tightened state, the screw rod of the locking screw locks the first insertion end and the second insertion end. When in the loosened state, the locking screw is separated from the first insertion end portion and the second insertion end portion.

[0011] By adopting the above technical solution, when it is necessary to adjust the relative position of the connecting rod, by loosening the locking screw, when the first insertion end and the second insertion end loosen the clamping of the telescopic support leg, there is no hindrance, so that the position of the clamping piece and the connecting rod can be adjusted, so as to facilitate the partition fixedly arranged on the connecting rod to block at different positions.

[0012] Optionally, a set of adjustment holes are provided in both the first plug end and the second plug end. There are at least two adjustment holes in a set, and the at least two adjustment holes are arranged at intervals. When the screw rod of the locking screw is inserted into the adjustment holes at different distances, the size of the enclosing hole increases or decreases.

[0013] By adopting the above technical solution, the adjustment holes and the locking screws cooperate so that after the locking screws are inserted into different adjustment holes and tightened and fixed, the holding pieces can form enclosing holes of different sizes, thereby facilitating adaptation to telescopic connecting legs of different sizes or facilitating adjustment by changing the size of the enclosing hole.

[0014] The first plug end and the second plug end insert different adjustment holes and locking screws for clamping.

[0015] Optionally, a guiding surface is provided at the notch of the insertion slot, and the guiding surface is used to guide the first plug end and the second plug end to be inserted into the insertion slot.

[0016] By adopting the above technical solution, the provision of the guiding surface enables the first plug end and the second plug end to be guided when inserted into the insertion slot, so as to be inserted quickly and accurately, which helps to improve the installation efficiency.

[0017] Optionally, separating grooves are provided at the ends of the holding piece close to the first plug end and the second plug end. The separating grooves extend along the length direction of the holding piece. The separating grooves are used to separate the first plug end and the second plug end into at least two sub-plug ends. The adjustment holes are provided on the sub-plug ends, and the number of the locking screws corresponds to the number of the sub-plug ends.

[0018] By adopting the above technical solution, the provision of the separating grooves enables the first plug end and the second plug end to respectively form two sub-plug ends to increase the number of sub-plug ends. Thus, when a locking relationship is formed between the corresponding number of locking screws and sub-plug ends, it helps to improve the connection firmness between the holding piece and the connecting block.

[0019] Optionally, guiding baffles are provided on two parallel side walls extending from the notch of the insertion slot. When the first plug end and the second plug end are inserted into the insertion slot, the two guiding baffles guide the holding piece to enclose into a rectangular shape.

[0020] By adopting the above technical solution, the guiding baffles guide and limit the insertion of the holding piece, so that the enclosing hole formed by the holding piece encloses into a rectangle, thereby facilitating cooperation and clamping with the telescopic table legs arranged in a rectangle.

[0021] In a second aspect, the present application also provides a connecting rod to which the above-mentioned pipe clip is applied.

[0022] A connecting rod includes:

[0023] A connecting rod body is provided with an installation hole that penetrates through two end faces of the connecting rod body, and both side notches of the installation hole are respectively for inserting the connecting blocks of the corresponding pipe clips;

[0024] An adjusting screw is arranged at the end of the connecting rod body. A positioning groove is provided on the adjacent side walls of the connecting block and the adjusting screw. When the adjusting screw is tightened, the screw rod thereof is inserted and abuts against the bottom of the positioning groove.

[0025] By adopting the above technical solution, the connecting rod and the connecting block are connected and fixed by the adjusting screw, so that both ends of the connecting rod can be tightened by the corresponding clamping pieces and telescopic support legs, and corresponding position adjustment can be performed to adjust the relative position of the partition plate through the connecting rod.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. When it is necessary to adjust the relative position of the connecting rod, by loosening the locking screw, the first insertion end and the second insertion end are not hindered when loosening the tightening of the telescopic support leg, so that the position of the clamping piece and the connecting rod can be adjusted, so that the partition plate fixedly arranged on the connecting rod can block different positions;

[0028] 2. The adjustment hole and the locking screw cooperate so that after the locking screw is inserted into different adjustment holes and tightened and fixed, the clamping piece can form saturation holes of different sizes, so as to facilitate adapting to telescopic connecting legs of different sizes, or facilitating adjustment by changing the size of the enclosing hole;

[0029] 3. The provision of the guiding surface enables the first insertion end and the second insertion end to be guided when inserted into the insertion groove, so as to be inserted quickly and accurately, which helps to improve the installation efficiency. Description of the Drawings

[0037] The following further describes this application in detail with reference to the Figure 1-6 accompanying drawings. In this embodiment, the direction indicated by the z-axis of the coordinate axis in the figure is taken as the up direction, the direction indicated by the x-axis is taken as the left direction, and the direction indicated by the y-axis is taken as the right direction as a reference for use, and the directions of the coordinate axes do not represent the actual directions during use.

[0038] First, an embodiment of this application discloses a hoop. Referring to Figure 1-3 , the hoop includes a connecting block 1, a clamping piece 2 and a locking screw 3. The connecting block 1 is used to connect and fix to the connecting rod. An insertion groove 111 is formed on the lower side of the connecting block 1 for the clamping piece 2 to be inserted. When the clamping piece 2 is inserted into the insertion groove 111, an enclosing hole 23 is formed. The enclosing hole 23 is used to tightly hold the telescopic support leg. The locking screw 3 is arranged on the connecting block 1. When tightened, it drives the enclosing hole 23 to contract, and when loosened, it drives the enclosing hole 23 to expand, so as to adjust the relative position between the clamping piece 2 and the telescopic support leg, and at the same time change the relative position between the connecting rod and the partition.

[0039] Among them, the locking screw 3 has a tightened state and a loosened state. When the locking screw 3 is in the tightened state, the screw rod of the locking screw 3 abuts against and limits the clamping piece 2, driving the clamping piece 2 to tightly hold the telescopic support leg of the furniture. When the locking screw 3 is in the loosened state, the locking screw 3 is away from the clamping piece 2. At this time, the clamping piece 2 can adjust the size of the enclosing hole 23, so that the saturated piece is separated from the outer side wall of the telescopic support leg, facilitating the adjustment of the relative position of the connecting rod.

[0040] Referring to Figure 2 and Figure 3, the connecting block 1 is provided with a connecting end portion 11 and a mounting portion 12. The mounting portion 12 is disposed on the upper side of the connecting block 1, and the connecting end portion 11 is disposed on the lower side of the connecting block 1. A corresponding insertion groove 111 is opened on the lower side wall of the connecting end portion 11, and the insertion groove 111 penetrates through the connecting block 1 and extends upward, so that it is not easy to be hindered when the clamping piece 2 is inserted.

[0041] Refer to Figure 3 and Figure 4 , the connecting block 1 includes a first connecting block 13 and a second connecting block 14. The first connecting block 13 and the second connecting block 14 are symmetrically arranged, and a positioning hole 131 is opened on the side wall of the first connecting block 13 facing the second connecting block 14. A positioning block 141 is fixedly arranged on the side wall of the second connecting block 14 facing the first connecting block 13. When the positioning block 141 is inserted into the positioning hole 131, the edges of the opposite side walls of the first connecting block 13 and the second connecting block 14 coincide with each other.

[0042] Refer to Figure 3 and Figure 4 , a threaded hole 15 is opened on the left side wall of the connecting block 1. The threaded hole 15 sequentially penetrates through the second connecting block 14 and the first connecting block 13. The threaded hole 15 is for the locking screw 3 to be inserted and threadedly connected. In addition, it should be further explained that the clamping piece 2 includes a first plugging end 21 and a second plugging end 22. Partition grooves 25 are opened on the side walls of the first plugging end 21 and the second plugging end 22 near the ends. The partition grooves 25 extend along the length direction of the clamping piece 2, so that both the first plugging end 21 and the second plugging end 22 form two sub-plugging ends 24. A set of adjustment holes 241 is opened on each sub-plugging end 24. The number of each set of adjustment holes 241 is two, and the two adjustment holes 241 are arranged at intervals along the length direction of the corresponding sub-plugging end 24. The number of the locking screws 3 corresponds to the number of the adjustment holes 241. During installation, by inserting the sub-plugging end 24 into the insertion groove 111 and aligning the adjustment holes 241 with the threaded hole 15, and then tightening the locking screw 3 by rotation, the screw rod of the locking screw 3 plays a role of abutting and limiting the sub-plugging end 24. In addition, the deeper the sub-plugging end 24 is inserted into the insertion groove 111, the smaller the size of the enclosure hole 23 formed by the clamping piece 2, and vice versa, the larger the formed enclosure hole 23.

[0043] Refer to Figure 3 and Figure 4 , in order to facilitate the insertion and installation of the sub-plugging end 24, a guiding surface 112 is opened on the inner wall of the slot opening of the insertion groove 111. The guiding surface 112 is inclined gradually toward the center of the slot opening of the insertion groove 111, so that when the sub-plugging end 24 contacts the guiding surface 112, it can automatically slide and insert toward the side of the insertion groove 111.

[0044] Refer to Figure 3 and Figure 4, in order to enable the clamping piece 2 to form an enclosure hole 23 adapted to the rectangular telescopic support legs after being inserted into the insertion groove 111, guide baffles 16 are fixedly arranged on the left and right side edges of the insertion groove 111 near the slot opening along the side walls. The guide baffles 16 extend downward, and the two guide baffles 16 are parallel to each other. When the sub-insertion end 24 is inserted into the insertion groove 111, the two guide baffles 16 are in close contact with the adjacent side walls of the clamping piece 2, so that the two parallel side edges of the clamping piece 2 form a rectangle. It should be further noted that the clamping piece 2 is made of an elastic material, and certain plastic creases are formed on the inner wall of the enclosure hole 23, so that the saturated piece can maintain a rectangular shape when contracting.

[0045] The implementation principle of a kind of hoop in the embodiment of the present application is as follows: when the position of the connecting rod needs to be adjusted, the locking screw 3 is adjusted to the loosened state, so that the state between the clamping piece 2 and the telescopic support legs is switched from the tightened state to the relaxed state, so as to facilitate the relative position adjustment of the connecting rod. After the relative position adjustment is completed, the locking screw 3 is adjusted to the tightened state, so that the connecting rod and the telescopic support legs are relatively fixed.

[0046] In a second aspect, the present application provides a connecting rod, which is applied with the hoop as described above.

[0047] Referring to Figure 5 and Figure 6 , the connecting rod includes a connecting rod main body 4 and an adjusting screw 5. The connecting rod main body 4 is provided with a mounting hole 41, and the mounting hole 41 penetrates through the upper and lower end faces of the connecting rod main body 4. The shape and size of the mounting hole 41 match the mounting part 12 of the hoop, so that after the mounting part 12 is inserted into the mounting hole 41, the connecting end 11 and the side wall of the mounting hole 41 form abutting and limiting.

[0048] Referring to Figure 6 , threaded through holes 42 are respectively provided on the front side walls of the connecting rod main body 4 near the two ends, the number of the threaded through holes 42 corresponds to the number of the adjusting bolts, and a positioning groove 121 is provided on the front side wall of the mounting part 12 for the screw rod of the adjusting bolt to be inserted and abutted. During installation, by inserting the mounting part 12 into the mounting hole 41, the threaded through hole 42 and the positioning groove 121 are aligned, and then the adjusting screw 5 is threadedly connected with the threaded through hole 42. When the screw rod of the adjusting bolt is inserted into the bottom of the positioning groove 121, a relative clamping and limiting is formed between the mounting part 12 and the connecting rod.

[0049] In this embodiment, corresponding hoops are fixedly arranged at both ends of the connecting rod, so as to facilitate the fixing and relative position adjustment of the two ends of the connecting rod and the corresponding telescopic support legs.

[0050] The implementation principle of a connecting rod in an embodiment of this application is as follows: It is fixed by adjusting the screw 5 and the corresponding hoop, so that both ends of the connecting rod body 4 can be tightly fixed to the telescopic support leg through the hoop. When it is necessary to adjust the relative position of the connecting rod, by adjusting the locking screw 3 on the hoop, the locking screw 3 is adjusted from the tightened state to the loosened state, so that the clamping piece 2 does not tightly clamp the telescopic support leg, facilitating the adjustment of the relative position.

[0051] The above are all preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
