Detailed implementation mode

[0042] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0044] Please refer to Figure 1 and Figure 2 , in the related art, the size of the door row of the flush door 100' cannot be adjusted, resulting in the inability to match access channels of different sizes. The door row of the flush door 100' includes two parts, namely the main door row assembly 110' and the sub - door row assembly 120', and the main door row assembly 110' and the sub - door row assembly 120' are locked together by self - tapping screws 190'. However, the above - mentioned scheme of directly using self - tapping screws 190' for locking is prone to the following problems:

[0045] (1) If the second crossbeam 121' of the secondary door row assembly 120' is made of metal material, since the self-tapping screw 190' directly drills a screw hole in the second crossbeam 121', this screw hole is prone to water seepage. Therefore, in outdoor or humid environments, oxidation and rusting are extremely likely to occur at the screw hole of the second crossbeam 121'.

[0046] (2) Vibration will occur when opening and closing the door. In the long term, the self-tapping screw 190' will become loose, making the connection between the first crossbeam 111' and the second crossbeam 121' insecure.

[0047] Based on this, this application hopes to provide a solution that can solve but is not limited to the above technical problems, and its detailed content will be elaborated in the subsequent embodiments.

[0048] Please refer to Figure 3 , this application provides a flat push door 100, which can also be called a sliding door, a swing door, etc. It can be but is not limited to being applied to the access channels of communities, schools, warehouses, and factories.

[0049] The flat push door 100 includes a head main frame assembly 20, a tail main frame assembly 30, and the door row 10 described in any of the following embodiments. Among them, the head main frame assembly 20 and the tail main frame assembly 30 are spaced opposite to each other. The main door row assembly of the door row 10 is rotatably connected to the head main frame assembly 20, that is, the door row 10 can rotate around the head main frame assembly 20. The secondary door row assembly of the door row 10 can be detached from or connected to the tail main frame assembly 30. That is to say, there are two relationships between the door row 10 and the tail main frame assembly 30. One is that the door row 10 is separated from the tail main frame assembly 30, and the other is that the door row 10 is fixed together with the tail main frame assembly 30.

[0050] From another perspective, the flat push door 100 has two states: an open state and a closed state. When the flat push door 100 is in the open state, the door row 10 is detached from the tail main frame assembly 30; when the flat push door 100 is in the closed state, the door row 10 is connected to the tail main frame assembly 30. During the process of the flat push door 100 switching between the open state and the closed state, the door row 10 rotates around the head main frame assembly 20.

[0051] Among them, the door row 10 and the head main frame assembly 20 can be rotatably connected by but not limited to a top and bottom shaft. The door row 10 and the tail main frame assembly 30 can be controllably detached from or connected to by but not limited to an electromagnetic lock.

[0052] Next, the door row 10 in the flat push door 100 will be specifically introduced with reference to the drawings.

[0053] Please refer to Figure 3 and Figure 4, this application provides a door row 10, and the door row 10 includes: a main door row assembly 110, a secondary door row assembly 120, and a locking assembly 130.

[0054] Among them, the main door row assembly 110 is used for rotatably connecting to the first main frame assembly 20. The main door row assembly 110 includes two first cross beams 111 arranged at intervals up and down, and a plurality of first vertical rods 112. The plurality of first vertical rods 112 are arranged at intervals along the extending direction of the first cross beam 111 and are connected to the first cross beam 111. The interval distances of the plurality of first vertical rods 112 may be the same or different. The first cross beam 111 has an accommodation space Q (as Figure 4 shown), that is, the first cross beam 111 is a hollow structure. Of course, the vertical rods can also adopt a hollow structure. Adopting a hollow structure is beneficial to saving materials and reducing weight. The cross-sectional shapes of the first cross beam 111 and the first vertical rods 112 can be, but are not limited to, rectangular, circular, triangular, etc. In this application, a rectangle is used for exemplary illustration. The materials of the first cross beam 111 and the first vertical rods 112 can be, but are not limited to, metal, plastic, etc. Of course, in other embodiments, the first vertical rods 112 may not be provided on the main door row assembly 110. For example, the first vertical rods 112 can be replaced with light boxes to display advertisements, or LED boards can be used instead of advertisements for publicity.

[0055] Among them, the secondary door row assembly 120 is used for detachably connecting to the tail main frame assembly 30. The secondary door row assembly 120 includes two second cross beams 121 arranged at intervals up and down, and a plurality of second vertical rods 122. The plurality of second vertical rods 122 are arranged at intervals along the extending direction of the second cross beam 121 and are connected to the second cross beam 121. The interval distances of the plurality of second vertical rods 122 may be the same or different. Both the second cross beam 121 and the second vertical rods 122 can adopt a hollow structure, so that materials can be saved and the weight can be reduced. The cross-sectional shapes of the second cross beam 121 and the second vertical rods 122 can be, but are not limited to, rectangular, circular, triangular, etc. In this application, a rectangle is used for exemplary illustration. The materials of the second cross beam 121 and the second vertical rods 122 can be, but are not limited to, metal, plastic, etc.

[0056] The second cross beam 121 is telescopically inserted into the accommodation space Q of the first cross beam 111 along a preset direction F (as Figure 4 shown). Among them, the preset direction F is the relative direction of the main door row assembly 110 and the secondary door row assembly 120. During the assembly process of the main door row assembly 110 and the secondary door row assembly 120, by changing the insertion depth of the second cross beam 121 into the first cross beam 111, the size of the door row 10 in the preset direction F can be adjusted, so as to adapt to the widths of different access channels.

[0057] Among them, at least one locking component 130 is provided between the two first cross beams 111 and the two second cross beams 121. The locking component 130 is used to lock the main door row component 110 and the sub-door row component 120 together (as Figure 4 shown). The locking component 130 presses the first cross beam 111 and the second cross beam 121.

[0058] The locking component 130 is used to prevent the second cross beam 121 from moving relative to the first cross beam 111 along the preset direction F. Specifically, the locking component 130 presses the first cross beam 111 and the second cross beam 121 in the direction perpendicular to the preset direction F. When the first cross beam 111 and the second cross beam 121 are subjected to an external force from the preset direction F, the locking component 130 will apply a frictional force along the preset direction F to the squeezed first cross beam 111 and second cross beam 121, and this frictional force will prevent the first cross beam 111 and the second cross beam 121 from generating relative movement in the preset direction F. In other words, the present application utilizes the squeezing effect of the locking component 130 to lock and fix the first cross beam 111 and the second cross beam 121 together.

[0059] In summary, in the door row 10 provided in the present application, since the second cross beam 121 is telescopically inserted into the first cross beam 111, the overall width of the door row 10 composed of the main door row component 110 and the sub-door row component 120 can be adjusted, so as to be adapted to different sizes of access channels. In addition, since the locking component 130 forms a squeezing effect on the first cross beam 111 and the second cross beam 121, when the first cross beam 111 or the second cross beam 121 is subjected to an external force from the preset direction F, the locking component 130 will form a frictional effect along the preset direction F on the squeezed first cross beam 111 and second cross beam 121, and through this frictional effect, the relative movement of the first cross beam 111 and the second cross beam 121 in the preset direction F can be prevented. Therefore, the main door row component 110 and the sub-door row component 120 can be locked and fixed together by the locking component 130.

[0060] Next, two specific structures of the locking component 130 and the locking principle of the locking component 130 on the first cross beam 111 and the second cross beam 121 will be specifically introduced with reference to the accompanying drawings.

[0061] The first locking component structure ( Figures 3 to 8 )

[0062] In a feasible implementation, the locking assembly 130 realizes the fixed connection between the first crossbeam 111 and the second crossbeam 121 only through the diagonal brace 131. Specifically, the locking assembly 130 includes a diagonal brace 131, which is arranged in the accommodation space Q and located between the inner wall surface of the first crossbeam 111 and the outer wall surface of the second crossbeam 121. The diagonal brace 131 presses against the inner wall surface of the first crossbeam 111 and the outer wall surface of the second crossbeam 121, so as to fixedly connect the first crossbeam 111 and the second crossbeam 121. That is to say, the diagonal brace 131 is located between the first crossbeam 111 and the second crossbeam 121, and the opposite sides of the diagonal brace 131 press against the first crossbeam 111 and the second crossbeam 121 respectively. When an external force from the preset direction F acts on the first crossbeam 111 or the second crossbeam 121, friction will be generated between the first crossbeam 111 and the diagonal brace 131, and friction will also be generated between the second crossbeam 121 and the diagonal brace 131. Through the above two friction effects, the relative movement between the first crossbeam 111 and the second crossbeam 121 in the preset direction F can be prevented, thereby realizing the fixed connection between the first crossbeam 111 and the second crossbeam 121

[0063] In another feasible implementation, the locking assembly 130 realizes the fixed connection between the first crossbeam 111 and the second crossbeam 121 through the diagonal brace 131, the outer bushing 132 and the first fastener 133. Specifically, the locking assembly 130 further includes an outer bushing 132 and a first fastener 133. The outer bushing 132 is fixed to the end of the first crossbeam 111, and the outer bushing 132 is provided with a first mounting hole X1. The first fastener 133 passes through the first mounting hole X1 and is connected to the diagonal brace 131. The diagonal brace 131 and the outer bushing 132 cooperate to press against the first crossbeam 111 and the second crossbeam 121, so as to fixedly connect the first crossbeam 111 and the second crossbeam 121. The functions of the diagonal brace 131, the outer bushing 132 and the first fastener 133 will be further described below

[0064] Please refer to Figure 4 、 Figures 6 to 8 It should be noted that Figure 4 and Figure 6The cutting positions of the shown cross-sectional views are different. The locking assembly 130 includes a brace 131, an outer bushing 132, and a first fastener 133. The brace 131 is disposed within the accommodation space Q and is located between the inner wall surface of the first cross beam 111 and the outer wall surface of the second cross beam 121. The outer bushing 132 is fixed to the end of the first cross beam 111. The outer bushing 132 is provided with a first mounting hole X1, and the first fastener 133 passes through the first mounting hole X1 to be connected to the brace 131, so that the brace 131 and the outer bushing 132 cooperate to squeeze the first cross beam 111 and the second cross beam 121.

[0065] Specifically, the first fastener 133 is used to drive the brace 131 to move along a preset direction F during the assembly process, so that the brace 131 and the outer bushing 132 abut against each other, and then the brace 131 and the outer bushing 132 cooperate to squeeze the first cross beam 111 and the second cross beam 121.

[0066] In the first embodiment, the outer bushing 132 deforms under the abutting action of the brace 131 and then squeezes the inner wall surface of the first cross beam 111, and the brace 131 deforms under the abutting action of the outer bushing 132 and then squeezes the outer wall surface of the second cross beam 121. As Figure 7 shown, in Figure 7 , the inclined cut of the brace 131 faces upward, and the inclined cut of the outer bushing 132 faces downward.

[0067] In the second embodiment, the outer bushing 132 deforms under the abutting action of the brace 131 and then squeezes the outer wall surface of the second cross beam 121, and the brace 131 deforms under the abutting action of the outer bushing 132 and then squeezes the inner wall surface of the first cross beam 111, that is, on the basis of the structure shown in Figure 7 , the inclined cut of the brace 131 is set to face downward, and the inclined cut of the outer bushing 132 is set to face upward.

[0068] In the third embodiment, a tapered groove is provided in the middle of the outer bushing 132, the brace 131 is provided with a tapered structure adapted to the shape of the tapered groove, the tapered structure of the brace 131 is inserted into the tapered groove, and the outer bushing 132 deforms under the abutting action of the tapered structure and then abuts against both the inner wall surface of the first cross beam 111 and the outer wall surface of the second cross beam 121 at the same time.

[0069] In the fourth embodiment, a tapered groove is provided in the middle of the brace 131, the outer bushing 132 is provided with a tapered structure adapted to the shape of the tapered groove, the tapered structure of the outer bushing 132 is inserted into the tapered groove, and the brace 131 deforms under the abutting action of the tapered structure and then abuts against both the inner wall surface of the first cross beam 111 and the outer wall surface of the second cross beam 121 at the same time.

[0070] For the above four implementation manners, the present application only takes the first implementation manner as an example for illustration.

[0071] Please refer to Figure 9 , the outer bushing 132 is provided with an inclined groove X4 that cooperates with the diagonal brace 131, and the diagonal brace 131 is disposed in the inclined groove X4. That is to say, the outer bushing 132 is provided with an inclined groove structure (i.e., the inclined groove X4, which can also be called an inclined cut), and the shape of the diagonal brace 131 matches the shape of the inclined groove X4, that is, the diagonal brace 131 is also provided with an inclined cut.

[0072] Please refer to Figure 9 , the outer bushing 132 is annular, and the outer bushing 132 is sleeved on the second cross beam 121 and fixed to the end of the first cross beam 111. Specifically, the outer bushing 132 can be annular, sleeved on the outer periphery of the second cross beam 121, and fixed to the end of the first cross beam 111, and at least part of the outer bushing 132 is located between the inner wall surface of the first cross beam 111 and the outer wall surface of the second cross beam 121. By setting it like this, the inner wall surface of the first cross beam 111 and the outer wall surface of the second cross beam 121 can be spaced apart to avoid scratching each other during the process of inserting the second cross beam 121 into the first cross beam 111. The outer bushing 132 can be made of an elastic material (such as rubber) or a plastic material (such as plastic), which can play a certain buffering role between the first cross beam 111 and the second cross beam 121, and at the same time can also prevent the first cross beam 111 and the second cross beam 121 from being scratched by the outer bushing 132.

[0073] Regarding the fixing method of the outer bushing 132 to the first cross beam 111, it can be fixed using threaded parts (such as screws, bolts, etc.). For example, the locking assembly 130 further includes a fastening screw 134. The first cross beam 111 is provided with a first assembly hole U1, the outer bushing 132 is provided with a second assembly hole U2, the fastening screw 134 passes through the first assembly hole U1 and is inserted into the second assembly hole U2, and the fastening screw 134 is in threaded cooperation with the second assembly hole U2, as Figure 4 shown. The outer bushing 132 and the first cross beam 111 can also be fixed by a snap connection method. For example, the outer bushing 132 is provided with a snap structure 1321, the first cross beam 111 is provided with a first assembly hole U1, and the snap structure 1321 forms a snap connection with the first assembly hole U1, as Figure 7 shown. Of course, there are other fixing methods for the outer bushing 132 and the first cross beam 111, which will not be elaborated here one by one. It can be understood that the outer bushing 132 is fixed to the first cross beam 111 by the fastening screw 134 or the snap connection method, which can prevent the outer bushing 132 from loosening easily.

[0074] Please refer to Figure 4 and Figure 6, the second crossbeam 121 has an insertion end 121D through which the second crossbeam 121 is inserted into the first crossbeam 111. The first fastener 133 passes through the first mounting hole X1 in the outer bushing 132 and then forms a connection with the diagonal brace 131. The first fastener 133 can drive the diagonal brace 131 to move away from the insertion end 121D along the preset direction F, and then form an abutting effect with the outer bushing 132. Then, the first crossbeam 111 and the second crossbeam 121 are squeezed jointly by the diagonal brace 131 and the outer bushing 132, thus achieving the locking effect.

[0075] Please refer to Figure 4 and Figure 6 , the door row 10 may further include an inner bushing 140 which is of an annular structure and sleeved on the outer periphery of the insertion end 121D of the second crossbeam 121. With such a setting, at least part of the inner bushing 140 is located between the inner wall surface of the first crossbeam 111 and the outer wall surface of the second crossbeam 121. It can be understood that the inner bushing 140 can separate the inner wall surface of the first crossbeam 111 from the outer wall surface of the second crossbeam 121, avoiding mutual scratching during the process of inserting the second crossbeam 121 into the first crossbeam 111. The inner bushing 140 can be made of an elastic material (such as rubber) or a plastic material (such as plastic), which can play a certain buffering role between the first crossbeam 111 and the second crossbeam 121, and at the same time can also prevent the first crossbeam 111 and the second crossbeam 121 from being scratched by the inner bushing 140. For the fixing method of the inner bushing 140 to the second crossbeam 121, it can be fixed using threaded parts (such as screws, bolts, etc.) or by a clamping method, etc. Specifically, reference can be made to the description of the fixing method of the outer bushing 132 to the first crossbeam 111 above.

[0076] Please refer to Figure 4 , the outer bushing 132 has a first inclined surface M1 facing the second crossbeam 121. The diagonal brace 131 has a second inclined surface M2 facing the first crossbeam 111 and a pressing surface M3 facing the second crossbeam 121. Among them, the first inclined surface M1 abuts against the second inclined surface M2. The pressing surface M3 presses the outer wall surface of the second crossbeam 121. Among them, the first inclined surface M1 and the second inclined surface M2 can both be flat surfaces and be parallel to each other.

[0077] Specifically, the included angle between the relative directions of the first inclined surface M1 and the second inclined surface M2 and the above-mentioned preset direction F is greater than 0° and less than 90°, that is, the first inclined surface M1 and the second inclined surface M2 are inclined with respect to the preset direction F. When the first fastener 133 drives the brace 131 to move along the preset direction F and away from the insertion end 121D of the second cross beam 121, the first inclined surface M1 abuts against the second inclined surface M2 and exerts an abutting action on the second inclined surface M2. Since the first inclined surface M1 and the second inclined surface M2 are inclined, the abutting force of the outer bushing 132 on the brace 131 can be decomposed into the following two component forces: one is the component force of the brace 131 in the direction towards the inner bushing 140; the other is the component force of the brace 131 in the direction towards the second cross beam 121. It can be understood that the component force of the brace 131 in the direction towards the second cross beam 121 will force the pressing surface M3 of the brace 131 to press against the outer wall surface of the second cross beam 121. Similarly, the reaction force exerted by the brace 131 on the outer bushing 132 will drive the outer bushing 132 to press against the inner wall surface of the first cross beam 111, thus achieving the locking effect. Moreover, the farther the brace 131 is from the insertion end 121D of the second cross beam 121, the greater the pressing action of the brace 131 on the second cross beam 121, and the greater the pressing action of the outer bushing 132 on the first cross beam 111, the stronger the locking effect, and vice versa.

[0078] In one embodiment, please refer to Figure 6 , the brace 131 is provided with a second mounting hole X2, and the first fastener 133 is inserted into the second mounting hole X2 and is in threaded cooperation with the second mounting hole X2. That is to say, the second mounting hole X2 is a threaded hole with internal threads, the first fastener 133 is provided with external threads, and the first fastener 133 can be screwed into the second mounting hole X2 with internal threads through the external threads. It can be understood that through the threaded cooperation, when the first fastener 133 rotates around its own central axis, the first fastener 133 can drive the brace 131 to approach or move away from the insertion end 121D of the second cross beam 121, thereby adjusting the locking effect. Among them, the first fastener 133 can be, but is not limited to, bolts, studs, etc.

[0079] In another embodiment, please refer to Figure 8, the diagonal brace 131 is provided with a second mounting hole X2. The locking assembly 130 further includes a first nut T1 (i.e., a nut), the first nut T1 is disposed on the diagonal brace 131, and the nut hole of the first nut T1 communicates with the second mounting hole X2. The first fastener 133 is inserted into the second mounting hole X2 and the nut hole and is in threaded cooperation with the nut hole. Specifically, the nut hole has an internal thread, the first fastener 133 is provided with an external thread, and the first fastener 133 can be screwed into the nut hole with an internal thread through the external thread. When the first fastener 133 rotates around its own central axis, the first fastener 133 can drive the diagonal brace 131 to approach or move away from the insertion end 121D of the second cross beam 121 through the first nut T1, thereby adjusting the locking effect. It should be noted that since the first nut T1 itself has a thread, the second mounting hole X2 can be provided with an internal thread or not. Among them, the first fastener 133 can be, but is not limited to, a bolt, a stud, etc. The first nut T1 can be made of a metal material. It can be understood that the first nut T1 made of a metal material is easy to obtain and has a relatively hard texture and is not prone to slipping of the teeth. It should be noted that the first nut T1 and the diagonal brace 131 can be integrally formed or separately formed and then assembled together.

[0080] Optionally, please refer to Figure 8 , the second mounting hole X2 includes a first sub-hole X21 and a second sub-hole X22. The diagonal brace 131 is further provided with a notch X3, and the notch X3 penetrates through the diagonal brace 131. The notch X3 is located between the first sub-hole X21 and the second sub-hole X22 and communicates with the first sub-hole X21 and the second sub-hole X22. The first nut T1 is disposed in the notch X3 so that the nut hole of the first nut T1 communicates with the first sub-hole X21 and the second sub-hole X22. It can be understood that this setting form facilitates the installation of the first nut T1, and the first nut T1 will be located between the first cross beam 111 and the second cross beam 121 and is not easily detached from the diagonal brace 131.

[0081] In any of the above related embodiments, the diagonal brace 131 can be made of a wear-resistant non-metal part. For example, the diagonal brace 131 is made of a rubber material, that is, the diagonal brace 131 is a rubber part. Another example is that the diagonal brace 131 is made of a plastic material, that is, the diagonal brace 131 is a plastic part. It can be understood that using a rubber part or a plastic part can avoid electrochemical reactions and can also isolate the above-mentioned fasteners from the first cross beam 111 and the second cross beam 121, thereby preventing the first cross beam 111 and the second cross beam 121 from rusting.

[0082] For the assembly process of the first locking component structure mentioned above, the outer sleeve 132 can be first sleeved on the second beam 121, and the diagonal brace 131 can be connected to the outer sleeve 132 using the first fastener 133. Then, the second beam 121 can be inserted into the accommodating space Q of the first beam 111, and the outer sleeve 132 can be inserted into the first beam 111, and the outer sleeve 132 can be fixed to the first beam 111 using the fastening screw 134. At this time, the use width of the door row 10 can be adjusted to match the size of the entrance and exit channel, and finally the first fastener 133 is tightened so that the diagonal brace 131 and the outer sleeve 132 abut against each other, so as to cooperate to squeeze the first beam 111 and the second beam 121, thereby achieving a locking effect.

[0083] The second locking assembly structure ( Figures 10 to 17 )

[0084] Please refer to Figures 10 to 13 The locking assembly 130 includes a locking member 135, a portion of which is sleeved on the outer periphery of the first beam 111 to press the first beam 111, and another portion of the locking member 135 is sleeved on the outer periphery of the second beam 121 to press the second beam 121 to prevent the second beam 121 from moving relative to the first beam 111 along the preset direction F. In other words, the locking member 135 simultaneously holds the first beam 111 and the second beam 121, so that the first beam 111 and the second beam 121 are locked and fixed together. The locking member 135 has a simple structure and good overall consistency, and can provide a better locking effect.

[0085] Please refer to Figure 11 The second cross beam 121 has an insertion end 121D, and the second cross beam 121 is inserted into the first cross beam 111 through the insertion end 121D. Figure 11 The door row 10 may further include an inner sleeve 140, which is sleeved on the outer periphery of the insertion end 121D of the second cross beam 121. For an introduction to the insertion end 121D and the inner sleeve 140, please refer to Figure 4 and Figure 6 Corresponding to the description in the embodiment.

[0086] Please refer to Figure 12 and Figure 13, the locking member 135 includes a first sleeve body 1351, and the first sleeve body 1351 has a first accommodation cavity Y1 and a first opening Y2 that are in communication with each other. Among them, the first accommodation cavity Y1 is used to accommodate the first cross beam 111, and the first accommodation cavity Y1 is adapted to the outer contour shape of the first cross beam 111, so that the first sleeve body 1351 can tightly hold and squeeze the first cross beam 111 better. For example, if the cross-sectional shape of the first cross beam 111 is rectangular, the first accommodation cavity Y1 is a rectangular chamber; if the cross-sectional shape of the first cross beam 111 is circular, the first accommodation cavity Y1 is a circular chamber.

[0087] Furthermore, the locking assembly 130 further includes a second fastener 136, and the second fastener 136 is connected to the first sleeve body 1351. The second fastener 136 is used to adjust the size of the first opening Y2 to change the size of the first accommodation cavity Y1. It can be understood that the smaller the first accommodation cavity Y1 is, the tighter the first sleeve body 1351 holds the first cross beam 111, and the stronger the squeezing effect is. On the contrary, the larger the first accommodation cavity Y1 is, the weaker the squeezing effect is. Therefore, during the installation process, the locking degree of the first sleeve body 1351 can be adjusted according to requirements through the second fastener 136.

[0088] Please refer to Figure 13 and Figure 14 , the first sleeve body 1351 includes a first pressing part 1351b, a first connecting part 1351c, a second pressing part 1351d, a first adjusting part 1351a and a second adjusting part 1351e.

[0089] The first adjusting part 1351a, the first pressing part 1351b, the first connecting part 1351c, the second pressing part 1351d and the second adjusting part 1351e are sequentially bent and connected and jointly enclose to form the first accommodation cavity Y1. Among them, the first pressing part 1351b and the second pressing part 1351d are oppositely arranged and are used to jointly squeeze the first cross beam 111. The first adjusting part 1351a and the second adjusting part 1351e both face the first connecting part 1351c.

[0090] The first adjusting part 1351a and the second adjusting part 1351e are opposite and spaced apart to form the first opening Y2, and the first adjusting part 1351a and the second adjusting part 1351e are connected to the second fastener 136.

[0091] Among them, the second fastener 136 can adjust the distance between the first adjusting portion 1351a and the second adjusting portion 1351e, thus changing the size of the first opening Y2. If the first opening Y2 becomes smaller, the first adjusting portion 1351a will drive the first pressing portion 1351b closer to the second pressing portion 1351d. At the same time, the second adjusting portion 1351e will drive the second pressing portion 1351d closer to the first pressing portion 1351b, that is, the first pressing portion 1351b and the second pressing portion 1351d approach each other, and the first accommodating cavity Y1 will correspondingly decrease, and the pressing effect is stronger. Correspondingly, if the first opening Y2 becomes larger, the first adjusting portion 1351a will drive the first pressing portion 1351b away from the second pressing portion 1351d. At the same time, the second adjusting portion 1351e will drive the second pressing portion 1351d away from the first pressing portion 1351b, that is, the first pressing portion 1351b and the second pressing portion 1351d move away from each other, and the first accommodating cavity Y1 will correspondingly increase, and the pressing effect is weaker.

[0092] Furthermore, the first adjusting portion 1351a is provided with a first accommodating hole V1, and the first accommodating hole V1 penetrates the first adjusting portion 1351a along the direction of the first adjusting portion 1351a towards the second adjusting portion 1351e. The second adjusting portion 1351e is provided with a second accommodating hole V2, and the second accommodating hole V2 penetrates the second adjusting portion 1351e along the direction of the first adjusting portion 1351a towards the second adjusting portion 1351e. The second fastener 136 is simultaneously inserted into the first accommodating hole V1 and the second accommodating hole V2.

[0093] In one embodiment, please refer to Figure 14 , the second fastener 136 is a threaded member with an external thread (such as a bolt or a stud), and at least one of the first accommodating hole V1 and the second accommodating hole V2 is a threaded hole provided with an internal thread, and the threaded hole forms a threaded fit with the second fastener 136, so that the interval distance between the first adjusting portion 1351a and the second adjusting portion 1351e can be adjusted by using the threaded fit.

[0094] In another embodiment, please refer to Figure 15 , the second fastener 136 is a threaded member with an external thread (such as a bolt or a stud), and the locking assembly 130 further includes a second nut T2 (i.e., a nut). At least one of the first accommodating hole V1 and the second accommodating hole V2 is provided with the second nut T2, and the nut hole of the second nut T2 forms a threaded fit with the second fastener 136, so that the interval distance between the first adjusting portion 1351a and the second adjusting portion 1351e can be adjusted by using the threaded fit. The second nut T2 can be made of a metal material. It can be understood that the second nut T2 made of a metal material is easy to obtain and has a relatively hard texture and is not prone to slipping of the teeth. Among them, the second nut T2 and the locking member 135 can be integrally formed or separately formed independently and then assembled together.

[0095] Please refer to Figure 12 and Figure 13 wherein, the locking member 135 includes a second sleeve body 1352 connected to the first sleeve body 1351, and the second sleeve body 1352 has a second accommodation cavity Z1 and a second opening Z2 that communicate with each other. Among them, the second accommodation cavity Z1 is used to accommodate the second cross beam 121, and the shape of the second accommodation cavity Z1 is adapted to the outer contour of the second cross beam 121, so that the second sleeve body 1352 can tightly hold and squeeze the second cross beam 121. For example, if the cross-sectional shape of the second cross beam 121 is rectangular, the second accommodation cavity Z1 is a rectangular chamber; if the cross-sectional shape of the second cross beam 121 is circular, the second accommodation cavity Z1 is a circular chamber.

[0096] Furthermore, the volume of the second accommodation cavity Z1 is smaller than the volume of the first accommodation cavity Y1 to be adapted to the smaller-sized second cross beam 121. The second sleeve body 1352 and the first sleeve body 1351 can be an integral structure. Adopting an integral structure has greater strength and is beneficial to improving the locking effect between the first cross beam 111 and the second cross beam 121.

[0097] Furthermore, the locking assembly 130 further includes a third fastener 137, and the third fastener 137 is connected to the second sleeve body 1352. The third fastener 137 is used to adjust the size of the second opening Z2 to change the size of the second accommodation cavity Z1. It can be understood that the smaller the second accommodation cavity Z1 is, the tighter the second sleeve body 1352 holds the second cross beam 121 and the stronger the squeezing effect is. On the contrary, the larger the second accommodation cavity Z1 is, the weaker the squeezing effect is. Therefore, during the installation process, the locking degree of the second sleeve body 1352 can be adjusted by the third fastener 137 according to requirements.

[0098] Please refer to Figure 13 and Figure 16 wherein, the second sleeve body 1352 includes a third squeezing portion 1352b, a second connecting portion 1352c, a fourth squeezing portion 1352d, a third adjusting portion 1352a and a fourth adjusting portion 1352e.

[0099] The third adjusting portion 1352a, the third squeezing portion 1352b, the second connecting portion 1352c, the fourth squeezing portion 1352d and the fourth adjusting portion 1352e are sequentially bent and connected and jointly enclose to form the second accommodation cavity Z1. Among them, the third squeezing portion 1352b and the fourth squeezing portion 1352d are oppositely arranged and are used to jointly squeeze the second cross beam 121. Both the third adjusting portion 1352a and the fourth adjusting portion 1352e face the second connecting portion 1352c.

[0100] The third adjusting part 1352a and the fourth adjusting part 1352e are opposite and spaced apart to form the second opening Z2, and the third adjusting part 1352a and the fourth adjusting part 1352e are connected to the third fastener 137.

[0101] Among them, the third fastener 137 can adjust the distance between the third adjusting part 1352a and the fourth adjusting part 1352e, thus changing the size of the second opening Z2. If the second opening Z2 becomes smaller, the third adjusting part 1352a will drive the third pressing part 1352b closer to the fourth pressing part 1352d. At the same time, the fourth adjusting part 1352e will drive the fourth pressing part 1352d closer to the third pressing part 1352b, that is, the third pressing part 1352b and the fourth pressing part 1352d approach each other, and the second accommodating cavity Z1 will correspondingly decrease, and the squeezing effect is stronger. Correspondingly, if the second opening Z2 becomes larger, the third adjusting part 1352a will drive the third pressing part 1352b away from the fourth pressing part 1352d. At the same time, the fourth adjusting part 1352e will drive the fourth pressing part 1352d away from the third pressing part 1352b, that is, the third pressing part 1352b and the fourth pressing part 1352d move away from each other, and the second accommodating cavity Z1 will correspondingly increase, and the squeezing effect is weaker.

[0102] Further, the third adjusting part 1352a is provided with a third accommodating hole W1, and the third accommodating hole W1 penetrates the third adjusting part 1352a along the direction of the third adjusting part 1352a towards the fourth adjusting part 1352e. The fourth adjusting part 1352e is provided with a fourth accommodating hole W1, and the fourth accommodating hole W1 penetrates the fourth adjusting part 1352e along the direction of the third adjusting part 1352a towards the fourth adjusting part 1352e. The third fastener 137 is simultaneously inserted into the third accommodating hole W1 and the fourth accommodating hole W1.

[0103] In one embodiment, please refer to Figure 16 , the third fastener 137 is a threaded part with an external thread (such as a bolt or a stud), and at least one of the third accommodating hole W1 and the fourth accommodating hole W1 is a threaded hole with an internal thread, and the threaded hole forms a threaded fit with the third fastener 137, so that the interval distance between the third adjusting part 1352a and the fourth adjusting part 1352e can be adjusted by using the threaded fit.

[0104] In another embodiment, please refer to Figure 17, the third fastener 137 is a threaded member with an external thread (such as a bolt or a stud), and the locking assembly 130 further includes a third nut T3 (i.e., a nut). At least one of the third receiving hole W1 and the fourth receiving hole W1 is provided with the third nut T3, and the nut hole of the third nut T3 forms a threaded fit with the third fastener 137. In this way, the threaded fit can be used to adjust the spacing distance between the third adjusting portion 1352a and the fourth adjusting portion 1352e. The third nut T3 can be made of a metal material. It can be understood that the third nut T3 made of a metal material is easy to obtain and has a relatively hard texture and is not prone to slipping of the threads. Among them, the third nut T3 and the locking member 135 can be integrally formed or separately formed independently and then assembled together.

[0105] In any of the above related embodiments, the locking member 135 can be selected as a wear-resistant non-metallic member. For example, the locking member 135 is made of a rubber material, that is, the locking member 135 is a rubber member. Another example is that the locking member 135 is made of a plastic material, that is, the locking member 135 is a plastic member. It can be understood that using a rubber member or a plastic member can avoid electrochemical reactions and can also isolate the above-mentioned fasteners from the first cross beam 111 and the second cross beam 121, thereby preventing the first cross beam 111 and the second cross beam 121 from rusting.
