Technical Field

[0001] The utility model relates to the field of cabinets, in particular to an iron tee for cabinet assembly. Background Art

[0002] A cabinet is an independent or self-supporting casing used to house electrical or electronic equipment. The cabinet is an indispensable component of electrical equipment and is the carrier of electrical control equipment. In order to be light, the cabinet is usually made of a combination of aluminum alloy and sheet metal, resulting in low load-bearing capacity and the need to use iron tees for reinforcement.

[0003] The Chinese utility model patent with publication number CN218830945U disclosed a three-way corner connector for a cabinet on April 7, 2023, including an integrated connection block and three corner connectors fixed on the integrated connection block, characterized in that: the three corner connectors are welded to the integrated connection block to form a whole; the end surface of the integrated connection block is welded with a corner connector; the annular protrusion provided on the outer periphery of the rear part of the integrated connection block is a limiting structure, and two adjacent surfaces of the limiting structure are provided with circular blind holes, and the surface of the limiting structure with the circular blind holes is welded with a corner connector. The utility model uses the corner connector set to form the profile of the cabinet, and concentrates the welding points on the connecting head. Compared with the original thin-walled connection sleeve solution, it has more solder, more convenient welding, and more reliable welding points. The manufacturing process of the utility model is simpler, and the assembly is more convenient and reliable.

[0004] However, the above-mentioned disclosed scheme has the following shortcomings: the existing three-way corner connector (iron tee with the same name) is fixed by welding for structural strength, but this method makes it difficult to distinguish between left and right when used in a cabinet at different corners in the cabinet, so that two shapes of iron tees are needed to connect the eight corners in the cabinet, and the two are very similar, so additional distinction is required during installation, which makes it impossible to maximize the installation efficiency and maximize the production efficiency. Utility Model Content

[0005] The utility model aims to solve the problem that the existing three-way corner connectors (iron tees of the same name) are fixed by welding for the sake of structural strength, but this method makes it difficult to distinguish between left and right when used in a cabinet at different corner positions in the cabinet, so that two shapes of iron tees are needed to connect the eight corners in the cabinet, and the two are very similar, so additional distinction is needed during installation, which makes it impossible to maximize the installation efficiency and the production efficiency. The utility model provides an iron tee for cabinet assembly.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model discloses an iron tee for cabinet assembly, comprising a movable square tube and a first array hole; the first array hole is provided on four sides of the movable square tube; a sleeved square tube is slidably sleeved on the movable square tube; two fixed square tubes are vertically fixedly connected to adjacent sides of the sleeved square tube; an external threaded hole is provided on the end of the fixed square tube; a fastener is inserted into the external threaded hole; the fastener is threadedly connected to the first array hole.

[0008] Furthermore, both ends of the movable square tube are penetrated with stepped holes; a symmetrical cylindrical shaft is slidably inserted in the through stepped hole; an entry and exit groove is opened in the through stepped hole corresponding to the symmetrical cylindrical shaft; and both ends of the symmetrical cylindrical shaft are symmetrically provided with hexagonal holes.

[0009] Furthermore, the movable square tube, the symmetrical cylindrical shaft, the sleeved square tube, the fixed square tube and the fasteners are all made of stainless steel.

[0010] Furthermore, the inlet and outlet grooves match the shape of the symmetrical cylindrical axis.

[0011] Furthermore, second array holes are formed through the four side surfaces of the fixed square tube.

[0012] The utility model provides an iron tee for cabinet assembly, which has the following beneficial effects:

[0013] 1. The utility model has a fastener located deep in the external threaded hole and passing through the fixed square tube and the sleeve square tube to be threadedly connected with the first array hole, so that the positions of the fixed square tube and the sleeve square tube on the movable square tube can be changed, so that the top angle position of the iron tee composed of two fixed square tubes and one movable square tube can be changed, so as to adapt to the eight corners of the inner side of the cabinet, so that one iron tee can complete the support and connection of one cabinet, so that the manufacturing and adjustment are simple, and one cabinet can be universal, which solves the problem that the existing iron tee has two directions and needs to manufacture two directions of iron tees;

[0014] 2. The utility model symmetrically opens hexagonal holes at both ends of the symmetrical cylindrical shaft, so that when a hexagonal wrench is inserted into the stepped hole, the symmetrical cylindrical shaft can be pushed to move and the symmetrical cylindrical shaft can be driven to rotate, so that the external threads at both ends of the symmetrical cylindrical shaft can be used to connect other objects, so that the shape of the iron tee can be changed to adapt to the fixed connection at right angles in the left and right directions, and it can also be fixed in multiple directions. On the premise that one end of the prior art is inserted with a matching bolt, the other end can also be threadedly connected. It only needs to open internal threads at both ends of the stepped hole, so that the bolts can be connected by themselves and the extension of the symmetrical cylindrical shaft is not hindered, which solves the problem of low strength caused by the existing iron tee being fixed with only one end inserted into the bracket and fixed with bolts.

[0022] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] It should be noted that all directional indications in the embodiments of the present invention (such as up-down-left-right-front-back...) are only used to explain the relative position relationship - movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0025] See also Figure 1-5As shown, an iron tee for cabinet assembly comprises a movable square tube 1 and a first array hole 3; the first array holes 3 are provided on four sides of the movable square tube 1; a sleeved square tube 6 is slidably sleeved on the movable square tube 1; two fixed square tubes 7 are vertically fixedly connected to the adjacent sides of the sleeved square tube 6; an external threaded hole 8 is provided at the end of the fixed square tube 7; a fastener 10 is inserted into the external threaded hole 8; the fastener 10 is threadedly connected to the first array hole 3; when working, the fastener 10 is located deep in the external threaded hole 8 and passes through the fixed square tube 7. The fixed square tube 7 and the sleeve square tube 6 are threadedly connected to the first array hole 3, so that the positions of the fixed square tube 7 and the sleeve square tube 6 on the movable square tube 1 can be changed, so that the top angle position of the iron tee composed of two fixed square tubes 7 and one movable square tube 1 can be changed, so as to adapt to the eight corners of the inner side of the cabinet, so that one iron tee can complete the support and connection of one cabinet, thereby making the manufacturing and adjustment simple, and one cabinet body can be universal, which solves the problem that the existing iron tee has two directions and needs to manufacture two directions of iron tees.

[0026] The two ends of the movable square tube 1 are penetrated by a through stepped hole 2; a symmetrical cylindrical shaft 4 is slidably inserted in the through stepped hole 2; an entry and exit groove 11 is opened in the through stepped hole 2 corresponding to the symmetrical cylindrical shaft 4; the two ends of the symmetrical cylindrical shaft 4 are symmetrically opened with a hexagonal hole 5; during operation, by symmetrically opening the hexagonal holes 5 at the two ends of the symmetrical cylindrical shaft 4, when a hexagonal wrench is inserted into the through stepped hole 2, the symmetrical cylindrical shaft 4 can be pushed to move while the symmetrical cylindrical shaft 4 can be driven to rotate, so that the external threads at the two ends of the symmetrical cylindrical shaft 4 can be used to connect other objects, so that the iron tee can change its shape to adapt to the fixed connection at the right angles in the left and right directions, and also the fixed connection in multiple directions. Under the premise of inserting a matching bolt at one end of the prior art, a threaded connection can be made at the other end. It is only necessary to open an internal thread at both ends of the through stepped hole 2, so that the bolt can be connected by itself and the extension action of the symmetrical cylindrical shaft 4 is not hindered, which solves the problem that the existing iron tee is fixed with only one end inserted into the bracket and fixed with bolts, resulting in low strength.

[0027] The movable square tube 1, the symmetrical cylindrical shaft 4, the sleeve square tube 6, the fixed square tube 7 and the fastener 10 are all made of stainless steel; when working, the entire structure is made of stainless steel, so that the service life will be longer, and the structural strength is high, and it is more stable for long-term use.

[0028] The entry and exit groove 11 matches the shape of the symmetrical cylindrical shaft 4; when working, the entry and exit groove 11 matches the shape of the symmetrical cylindrical shaft 4, so that the symmetrical cylindrical shaft 4 can enter the through-step hole 2 through the entry and exit groove 11, so that it can move at both ends in the through-step hole 2, so that it can be moved and rotated with a hexagonal wrench, so that the symmetrical cylindrical shaft 4 is equivalent to a bolt threaded connection with other objects, so that the movable square tube 1 has a fixed position in two directions, adapts to the fixation at right angles in the left and right directions, and at the same time, the connection strength is increased, which solves the problem that the existing iron tee fixation has only one end inserted into the bracket and is fixed with bolts, resulting in low strength.

[0029] The four sides of the fixed square tube 7 are penetrated with second array holes 9; when working, the second array holes 9 are penetrated with the four sides of the fixed square tube 7, so that it can be fixed on other objects or connected with other objects from four angles with bolts.

[0030] By adopting the above scheme, when the utility model is in use, the fastener 10 is located deep in the external threaded hole 8 and passes through the fixed square tube 7 and the sleeve square tube 6 to be threadedly connected with the first array hole 3, so that the position of the fixed square tube 7 and the sleeve square tube 6 on the movable square tube 1 can be changed, so that the top angle position of the iron tee composed of two fixed square tubes 7 and one movable square tube 1 can be changed, so as to adapt to the eight corners of the inner side of the cabinet, so that one iron tee can complete the support and connection of one cabinet, so that the manufacturing and adjustment are simple, and one cabinet can be universal, which solves the problem that the existing iron tee has two directions and needs to manufacture two directions of iron tees; by symmetrically opening hexagonal holes 5 at both ends of the symmetrical cylindrical shaft 4, When a hexagonal wrench is used to insert the through-step hole 2, the symmetrical cylindrical shaft 4 can be pushed to move and the symmetrical cylindrical shaft 4 can be driven to rotate, so that the external threads at both ends of the symmetrical cylindrical shaft 4 can be used to connect other objects, so that the shape of the iron tee can be changed to adapt to the fixed connection at right angles in the left and right directions, and it can also be fixed in multiple directions. On the premise that a matching bolt is inserted at one end of the prior art, a threaded connection can be made at the other end. It only needs to provide internal threads at both ends of the through-step hole 2, so that the bolts can be connected by themselves and the extension of the symmetrical cylindrical shaft 4 is not hindered, which solves the problem that the existing iron tee is fixed with only one end inserted into the bracket and fixed with bolts, resulting in low strength.
