Description

TECHNICAL FIELD

[0001] The utility model relates to the field of table, in particular, relate to a high stability table frame support structure. BACKGROUND

[0002] As Figure 1 And Figure 2 As shown in a typical folding support structure of the prior art, it mainly includes support feet and support tubes. The support tubes are hinged to the support feet by a pin shaft. When folding is needed, the support tubes can be turned down around the shaft of the pin shaft, so that the support tubes can be attached to the side wall of the support feet, thereby reducing the occupied space, facilitating storage or transportation. When the table is needed to be used, the support tubes are turned up until the side wall of the support tubes contacts the upper end surface of the support feet, at which time the support tubes are used to support the table top.

[0003] However, the above-mentioned folding support structure of the prior art has certain deficiencies. When the table top carries heavy objects, the contact area between the outer wall of the support tube and the upper end surface of the support feet bears a large pressure. Since the upper end surface of the support feet is relatively small in area, this concentrated stress can cause the outer wall of the support tube to be worn out greatly during long-term use. Over time, this continuous wear and tear can easily cause the material of the support tube to fatigue or even break, affecting the stability and service life of the support structure. SUMMARY

[0004] Therefore, the utility model aims at providing a high stability table frame support structure to improve the structural stability and service life.

[0005] In order to solve the above technical problems, the technical scheme of the utility model is as follows: a high stability table frame support structure, including support feet and support tubes, the support tubes are hinged to the support feet, the support tubes are provided with mounting grooves, the mounting grooves are connected with contact pieces for abutting against the end of the support feet, the contact pieces are connected with auxiliary pieces, the auxiliary pieces are used for abutting against the inner wall of the support tubes.

[0006] The technical scheme is realized by the following: a mounting groove is formed on the support pipe, a contact piece abutting against the end of the support leg is arranged in the mounting groove, and an auxiliary piece connected to the contact piece and abutting against the inner wall of the support pipe is arranged in the mounting groove. The technical scheme solves the problem of serious abrasion caused by the small contact area between the end face of the support leg and the outer wall of the support pipe. The contact piece bears the load from the support leg, avoiding the direct force abrasion of the outer wall of the support pipe. The auxiliary piece effectively supports and strengthens the force bearing area of the support pipe from the inside. Therefore, the outer wall of the support pipe and the inner wall of the support pipe bear the force simultaneously, the load transmission path is optimized, the stress is dispersed, the abrasion of the support pipe is significantly reduced, the durability and service life of the support pipe are greatly improved, and the overall stability and reliability are improved, especially when heavy load is borne.

[0007] As a preferred scheme of the utility model, the outer wall of the contact piece is provided with an abutting part surrounding the contact piece, the end of the contact piece is provided with an anti-falling part, the anti-falling groove is formed between the anti-falling part and the abutting part, the abutting part abuts against the opening of the mounting groove, and the anti-falling part is located in the inside of the support pipe and the inner wall of the mounting groove is located in the anti-falling groove.

[0008] The technical scheme is realized by the following: the contact piece is sent into the mounting groove at an inclined angle, the abutting part surrounding the outer wall of the contact piece moves to the opening of the mounting groove on the support pipe and tightly cooperates with the opening, at the same time, the anti-falling part is located in the inside space of the support pipe, and when the contact piece changes from the inclined angle to the flat state, the inner wall of the mounting groove can be located in the anti-falling groove.

[0009] As a preferred scheme of the utility model, the outer wall of the contact piece is connected with an anti-skid strip, and the anti-skid strip abuts against the inner wall of the support pipe.

[0010] The technical scheme is realized by the following: the anti-skid strip generates additional friction and contact pressure with the inner wall of the support pipe, effectively increases the fixing stability of the contact piece in the mounting groove, and inhibits the possible slight sliding or displacement of the contact piece. This further ensures that the contact piece can be accurately kept in the preset force bearing position, thereby guaranteeing the stability of load transmission and the fastening of the structure, and providing more reliable and stable support effect for the whole table frame support structure.

[0011] As a preferred scheme of the utility model, the side of the auxiliary piece towards the anti-falling part has an arc-shaped convex part, and when the contact piece is inserted into the support pipe at an inclined angle, the arc-shaped convex part contacts with the inner wall of the support pipe and serves as a guide point and a support point.

[0012] The arc-shaped convex part serves as a guide point and a supporting point when the contact piece is inserted into the supporting pipe at an inclined angle from the mounting groove, thereby solving the problem of inclined insertion and positioning of the assembly in a narrow space.

[0013] As a preferred scheme of the utility model, the auxiliary member is provided with reinforcing bevels on both sides, which are inclined from the end close to the contact piece to the end far from the contact piece.

[0014] The reinforcing bevels form a high-strength frame structure of the auxiliary member body, effectively solving the problem of bending, deformation or insufficient strength of the auxiliary member during transmission of the load from the contact piece to the inner wall of the supporting pipe, greatly improving the structural rigidity and load capacity of the auxiliary member.

[0015] As a preferred scheme of the utility model, the inner wall of the auxiliary member is provided with horizontal reinforcing ribs and vertical reinforcing ribs, and a grid structure is formed between the horizontal reinforcing ribs and the vertical reinforcing ribs.

[0016] The staggered horizontal reinforcing ribs and vertical reinforcing ribs form a high-efficiency and high-strength internal support framework of the auxiliary member, significantly improving the structural rigidity, compression resistance and deformation resistance of the auxiliary member, and solving the problem of buckling or fracture of the auxiliary member body when bearing the load from the contact piece.

[0017] As a preferred scheme of the utility model, the supporting leg is connected with a limiting member, the contact piece is provided with a connecting groove, the supporting pipe is flipped along the hinge to the end close to the supporting leg, and the limiting member is placed in the connecting groove, and the contact piece is provided with an elastic structure for limiting the limiting member from being pulled out of the connecting groove.

[0018] When the support pipe is turned over along the hinge towards the end close to the support foot, the limiting piece enters the inside of the connecting groove. When the limiting piece enters the predetermined position defined by the connecting groove, the elastic structure arranged on the contact piece elastically restricts the limiting piece. By limiting the limiting piece from escaping from the inside of the connecting groove, the stability and working reliability of the support pipe are significantly improved. Moreover, the inner wall of the connecting groove exerts a downward pressure on the limiting piece, causing the limiting piece to slightly deform, and at the same time, the limiting piece exerts a counterforce on the inner wall of the connecting groove, so that the limiting piece and the support pipe simultaneously exert a supporting force on the contact piece, to further improve the stability.

[0019] As a preferred scheme of the utility model, the elastic structure comprises a sliding groove, a sliding plate and an elastic piece, the sliding groove is arranged on the contact piece and communicates with the connecting groove, the sliding plate is slidingly connected in the sliding groove, the elastic piece is connected with the inner wall of the sliding groove and the sliding plate at two ends respectively, the sliding plate is penetrated into the connecting groove after moving along the sliding groove under the elastic force of the elastic piece, and the sliding plate is used for abutting against the limiting piece.

[0020] The above technical scheme is realized. Pressure is applied to the sliding plate, so that the sliding plate is located in the sliding groove. After the limiting piece is located in the connecting groove, the sliding plate is loosened, and the end of the sliding plate is arranged in the connecting groove under the elastic force of the elastic piece. At this time, the limiting piece is limited in the locking position formed between the bottom wall of the connecting groove and the sliding plate, so that the stability and working reliability of the support pipe are improved.

[0021] As a preferred scheme of the utility model, an inclined surface for abutting against the limiting piece is arranged at the end of the sliding plate close to the connecting groove, and the inclined surface is located at the side of the sliding plate close to the opening of the connecting groove.

[0022] The above technical scheme is realized. When the limiting piece enters the connecting groove along with the turning over of the support pipe, the end of the sliding plate extending into the connecting groove is met. At this time, the limiting piece slides along the inclined surface on the sliding plate. The configuration of the inclined surface converts the movement direction of the limiting piece into a force for pushing the sliding plate backward, so as to compress the elastic piece and temporarily retract the sliding plate into the sliding groove, allowing the limiting piece to enter the locking position of the connecting groove. The smoothness of use and the user operation experience are significantly improved.

[0023] As a preferred scheme of the utility model, a plurality of weight reduction grooves are arranged on the sliding plate and arranged along the length direction of the sliding plate. A placing groove communicating with the sliding groove is arranged on the outer wall of the support pipe. A sliding block is fixed on the sliding plate, the sliding block extends out of the placing groove, and a friction strip is fixed on the outer wall of the sliding block.

[0024] The multiple lightening grooves reduce the material usage, and significantly reduce the weight of the slide plate; when the user needs to unlock, the user's fingers press the friction strip. Under the pushing force of the fingers, the slide block drives the slide plate to overcome the elastic force of the elastic member, and moves backward along the sliding groove. The friction strip provides a high-friction contact surface, so that the user's fingers are not easy to slip when pressing the slide block, and the slide block can be moved more stably and labor-saving, so that the slide plate and the limiting member are smoothly unlocked. The convenience, comfort and efficiency of the user's manual unlocking operation are significantly improved. BRIEF DESCRIPTION OF DRAWINGS

Figure 3 To the accompanying drawings Figure 12 The specific embodiments of the present application are described in further detail below, so that the technical scheme of the present application is easier to understand and master.

[0039] A high-stability table frame support structure includes support feet 1 and a support pipe 2. Each support foot 1 includes a support section 3 and two fixed sections 4, wherein the two fixed sections 4 are respectively screwed to the two sides of the support section 3. The support pipe 2 is hingedly connected to the fixed sections 4 through pin shafts 30. The support pipe 2 can be folded by turning it down along the axis of the pin shaft 30, so that the side wall of the support pipe 2 abuts against the side wall of the support section 3. The support pipe 2 can be unfolded by turning it up along the axis of the pin shaft 30, so that the end of the support section 3 corresponds to the side wall of the support pipe 2. The support pipe 2 is a square tube.

[0040] A mounting groove 5 is formed in the side wall of the support pipe 2, and a contact piece 6 for abutting against the end of the support foot 1 is connected in the mounting groove 5. The contact piece 6 is integrally connected with an auxiliary piece 7. The end of the auxiliary piece 7 away from the contact piece 6 is used for abutting against the inner wall of the support pipe 2. The contact piece 6 and the auxiliary piece 7 are fixed by two parts.

[0041] An abutting portion 8 surrounding the contact piece 6 is integrally arranged on the outer wall of the contact piece 6. An anti-disengagement portion 9 is integrally arranged on the end of the contact piece 6, and an anti-disengagement groove 10 is formed between the anti-disengagement portion 9 and the abutting portion 8.

[0042] The contact piece 6 is inserted into the mounting groove 5 in an inclined posture, and then the contact piece 6 is gradually rotated to a flat state, so that the abutting portion 8 abuts against the opening of the mounting groove 5, and the anti-disengagement portion 9 is located inside the support pipe 2 and the inner wall of the mounting groove 5 is located in the anti-disengagement groove 10. Thus, the contact piece 6 is not easy to disengage from the mounting groove 5.

[0043] The anti-skid strips 11 are integrally connected to the outer wall of the contact piece 6, and a plurality of anti-skid strips 11 are arranged along the length direction of the contact piece 6. The anti-skid strips 11 are used to abut against the inner wall of the support pipe 2. The lower end of the anti-skid strip 11 is connected with the abutting part 8, so that the contact piece 6 is less likely to be pulled out of the mounting groove 5.

[0044] An arc-shaped protrusion 12 is integrally connected to the side of the auxiliary piece 7 facing the anti-pulling-out part 9. When the contact piece 6 is inserted into the support pipe 2 at an inclined angle from the mounting groove 5, the arc-shaped protrusion 12 contacts the inner wall of the support pipe 2 and serves as a guide point and a support point.

[0045] Reinforced inclined surfaces 13 are formed on both sides of the auxiliary piece 7, and the reinforced inclined surfaces 13 are inclined from the end close to the contact piece 6 to the end away from the contact piece 6 of the auxiliary piece 7.

[0046] Horizontal reinforcing ribs 14 and vertical reinforcing ribs 15 are integrally arranged on the inner wall of the auxiliary piece 7. A grid structure is formed between the plurality of horizontal reinforcing ribs 14 and the plurality of vertical reinforcing ribs 15.

[0047] A limiting piece 16 is fixedly connected to the fixed section 4, and the limiting piece 16 is in the form of a circular tube. A connecting groove 17 is formed on the side of the contact piece 6 facing the end of the support section 3, and the connecting groove 17 has a guide arc surface 18 at the opening thereof, so that the limiting piece 16 can smoothly enter the connecting groove 17.

[0048] The support pipe 2 is flipped along the pin shaft 30 to the end of the support section 3, and the limiting piece 16 is placed in the connecting groove 17. A resilient structure 19 is arranged on the contact piece 6 to limit the limiting piece 16 from being pulled out of the connecting groove 17.

[0049] The resilient structure 19 includes a sliding groove 20, a sliding plate 21, and a resilient piece 22. The sliding groove 20 is formed on the contact piece 6 and communicates with the connecting groove 17, and the sliding plate 21 is slidingly connected in the sliding groove 20. A protrusion 23 is integrally connected to the sliding plate 21, and the two ends of the resilient piece 22 abut against the inner wall of the sliding groove 20 and the protrusion 23, respectively. The resilient piece 22 is a spring. The sliding plate 21 moves along the sliding groove 20 under the elastic force of the resilient piece 22 and then penetrates into the connecting groove 17, and the sliding plate 21 is used to abut against the limiting piece 16.

[0050] A guide inclined surface 24 for abutting against the limiting piece 16 is formed on the end of the sliding plate 21 close to the connecting groove 17, and the guide inclined surface 24 is located on the side of the sliding plate 21 facing the opening of the connecting groove 17.

[0051] A plurality of lightening grooves 25 are formed on the sliding plate 21 and arranged along the length direction of the sliding plate 21.

[0052] The support pipe 2 is provided with a placing groove 26 in communication with the sliding groove 20 on the outer wall of the support pipe 2, and the length of the placing groove 26 is greater than the width of the connecting groove 17. The sliding block 27 is integrated on the sliding plate 21 and extends out of the placing groove 26. The inner recess 28 is provided on the outer wall of the sliding block 27, and the inner recess 28 is provided with two. The plurality of friction strips 29 are integrally connected on the inner recess 28 and the sliding block 27.

[0053] In the use state, the load of the support leg 1 is no longer directly applied to the outer wall of the support pipe 2, but is transmitted and dispersed through the contact piece 6 abutting against the end of the support leg 1 and the auxiliary piece 7 integrally connected and abutting against the inner wall of the support pipe 2, thereby completely solving the problem of friction and wear of the outer wall of the support pipe 2. The contact piece 6 is firmly clamped with the mounting groove 5 of the support pipe 2 through the abutting part 8, the anti-dropping part 9 and the anti-skid strip 11, and the stable installation is ensured. The strength of the auxiliary piece 7 is sufficient to reliably transmit the load through the self-strengthening slope 13, the internal transverse reinforcing rib 14 and the vertical reinforcing rib 15.

[0054] When the support pipe 2 is turned to the end of the support section 3 and the contact piece 6 abuts against the end of the support section 3, the limiting piece 16 on the support leg 1 is automatically clamped into the connecting groove 17 of the contact piece 6, and the locking is realized by the elastic structure 19. The user can conveniently manually unlock through the friction strips 29 on the outer sliding block 27.

[0055] Of course, the above is only a typical example of the present application, in addition to this, the present application can have other various specific implementation manners, and the technical solutions formed by equivalent replacement or equivalent transformation all fall within the scope of the present application.
