Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0027] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0029] Reference Attachment Figure 1-6 This embodiment provides an adjustable trough-type bridge support, which includes: a mounting base 100, a scissor arm group 200 and a limit frame 300. The scissor arm group 200 is provided on the mounting base 100 to adjust the distance between the two groups of limit frames 300 located at both ends thereof. When in use, the mounting base 100 is fixed to the building, the scissor arm group 200 is used to increase the distance between the two groups of limit frames 300, the trough-type bridge is placed on the limit frames 300, and then the distance between the limit frames 300 is reduced to clamp the trough-type bridge. The provision of the scissor arm group 200 increases the scope of application of this support, making it possible to change the distance between the limit frames 300 according to trough-type bridges of different sizes. This support can be manufactured according to the number of bridges to be supported, thereby reducing the waste of materials caused by the fact that sufficient brackets of each size are preset in traditional construction but are often not fully utilized.

[0030] The shape and structure of the mounting base 100 can be configured according to actual usage requirements. This is because to ensure that the support direction of the limit frame 300 is upward, the shape and orientation of the mounting base 100 when installed on the roof and facade of a building will inevitably vary to a certain extent. This embodiment only exemplifies some structures of the mounting base 100 suitable for installation on the facade of a building, but does not limit the scope of protection of this application. All types of mounting bases 100 that can meet the above-mentioned installation and support functions are included in the scope of protection of this application.

[0031] Reference Attachment Figure 1-3The mounting base 100 includes a flange base 110, a support rib 120 and a slide 130. The flange base 110 has a first mounting portion and a second mounting portion on both sides along the axial direction. The first mounting portion is provided with a plurality of countersunk holes 111 for installing countersunk screws for connecting the building; the support rib 120 is provided on the second mounting portion, and a slide groove 121 is provided on the top thereof. The extension direction of the slide groove 121 is consistent with the axis of the flange base 110; the scissor arm group 200 is provided at the top of the slide 130, and the bottom of the slide 130 is slidably set in the slide groove 121 and fixed by the locking member 140. By loosening the locking piece 140, sliding the slide 130, and tightening the locking piece 140, the distance between the slide 130 and the flange seat 110 can be adjusted, so as to adjust the distance between the limit frame 300 located on the scissor arm assembly 200 and the facade of the building, adapt to the complex electrical bridge wiring design, and accurately locate the supporting position of the limit frame 300 (that is, the installation position of the trough bridge), so as to accurately install the trough bridge and lay cables, ensure smooth construction, beautiful construction, and facilitate subsequent maintenance.

[0032] There are several optional ways to fix the slide 130 on the support rib 120, which can be selected and configured according to actual needs. The following are only some of the feasible ways as examples: a number of first fixing holes 122 are set on the side wall of the slide 121, and the first fixing holes 122 are evenly distributed along the length direction of the slide 121. Second fixing holes 131 with the same shape and direction as the first fixing holes 122 are set on the part of the slide 130 extending into the slide 121. The locking member 140 is inserted into the second fixing hole 131 and different first fixing holes 122, so that the slide 130 can be fixed at different positions on the slide 121.

[0033] In order to prevent the slide 130 from slipping off the top of the slide 121, the opening size of the top of the slide 121 can be set to be smaller than its internal size. For example, the longitudinal section of the slide 121 can be set to a trapezoid (the upper base is shorter than the lower base), an inverted T-shape, a pentagon, a hexagon or other shapes that meet the above-mentioned size requirements, and the bottom end of the slide 130 can be configured to be adapted thereto. Of course, on the basis of the above solution, the size of the portion of the slide 130 extending out of the slide 121 can be increased to improve the support stability of the scissor arm assembly 200 and the limit frame 300 (the geometric shape of the slide 130 can be configured according to needs and is not limited. For details, please refer to the attached Figure 3 ).

[0034] The locking member 140 can be a common pin or bolt, and the shapes of the inner walls of the first fixing hole 122 and the second fixing hole 131 can be adaptively configured accordingly, such as providing threads.

[0035] In order to improve the installation and disassembly ease of this bracket, a T-shaped bracket 112 is provided on the second mounting portion of the flange seat 110, and a T-shaped block 150 adapted to the T-shaped bracket 112 is provided on the side of the support rib 120. The cross-section of the T-shaped bracket 112 is T-shaped, with the narrow part facing the support rib 120 and open. The top of the T-shaped bracket 112 is open and the bottom is closed to facilitate the installation and support of the T-shaped block 150.

[0036] The T-shaped brackets 112 and T-shaped blocks 150 can be arranged in parallel in multiple numbers as needed to improve the fixing effect, such as 2, 3, 4, etc.

[0037] The support ribs 120 can be configured as additional Figure 3 The wedge-shaped block shown is larger at the top and smaller at the bottom. If necessary, the bottom of the wedge-shaped block can be hollowed out. While ensuring that the top of the support rib 120 can provide the setting space required for the slide groove 121, its own volume and weight can be reduced, the space occupancy can be reduced, and the bracket can be made lighter.

[0038] Reference Attachment Figure 4 The limiting frame 300 includes a bottom support plate 310 and a side baffle 320. The bottom support plate 310 is used to support the bridge frame; the side baffles 320 are respectively arranged on the separated sides of the two groups of bottom support plates 310 to limit the side walls of the bridge frame; a number of bridge frame connecting holes 321 are provided on the side baffles 320. When the bridge frame is placed on the bottom support plate 310 and the distance between the two limiting frames 300 is adjusted, bolts are passed through the bridge frame connecting holes 321 and the side walls of the bridge frame to achieve a stable connection and prevent skewing or falling.

[0039] Preferably, a U-shaped groove 311 with an opening toward the scissors arm assembly 200 can be provided on the bottom support plate 310, and the scissors arm assembly 200 can be clamped on the bottom plate of the U-shaped groove 311 to prevent it from protruding from the top surface of the bottom support plate 310, affecting the flatness of the contact surface between the bottom support plate 310 and the bridge frame, thereby improving the supporting stability.

[0040] The scissor arm group 200 includes two first scissor arms 210 and two second scissor arms 220, and each limit frame 300 is provided with a first scissor arm 210 and a second scissor arm 220, and the slide 130 is respectively hinged to one end of the first scissor arm 210 and one end of the second scissor arm 220 at a fixed point, and the hinge points of the first scissor arm 210 and the second scissor arm 220 on the mounting seat 100 may be the same or different; the other ends of the first scissor arm 210 and the second scissor arm 220 are both hinged to the limit frame 300, and the distance between the two ends is adjustable, that is, at least one of the two has an unfixed hinge point with the limit frame 300 (of course, both can be unfixed), and by adjusting the distance between the first scissor arm 210 and the second scissor arm 220 at this end, the distance between the limit frame 300 and the slide 130 is changed, that is, the distance between the two limit frames 300 is changed.

[0041] In order to simplify the adjustment difficulty, this embodiment is explained by taking the example that the hinge point of the second scissor arm 220 and the limit frame 300 is not fixed (see the attached Figure 5-6 ). That is: the first scissor arm 210 is hinged at one end of the length direction of the bottom plate of the U-shaped groove 311, and the other end of the length direction of the bottom plate of the U-shaped groove 311 is provided with a strip through hole 312, and the strip through hole 312 is consistent with the extension direction of the U-shaped groove 311, and a side wall of the strip through hole 312 is provided with a plurality of limiting grooves 313, and the position of each limiting groove 313 is preset according to the width size of each type of bridge frame actually used in construction (involving the spacing between the two limiting frames 300, the conversion between the hinge point of the first scissor arm 210 and the limiting frame 300 and the spacing between the limiting grooves 313, which can be configured according to actual needs and will not be elaborated here), a hinge rod 400 is passed through the second scissor arm 220, and an elastic member 500 is provided in the middle of the hinge rod 400, and a card ball 600 adapted to the shape of the limiting groove 313 is provided at the other end of the elastic member 500. Among them, the limiting groove 313 is only slightly recessed in the inner wall surface of the strip through hole 312, and the blocking ball 600 plays a positioning function when it contacts the limiting groove 313. When the limiting frame 300 or the scissor arm group 200 is not subject to external force, the contact between the two is stable, and a slight force is applied to the limiting frame 300 or the scissor arm group 200, the blocking ball 600 can be separated from the limiting groove 313, and slide together with the elastic member 500 and the hinge rod 400 in the strip through hole 312 to the next limiting groove 313.

[0042] By presetting multiple limit grooves 313 according to the size of the bridge used in construction, the construction workers are given a position indication. When the card ball 600 moves to the appropriate limit groove 313, it means that the spacing of the limit frame 300 is adapted to the size of the bridge. This can avoid over-limit or under-limit caused by the construction workers adjusting the spacing of the limit frame 300 only by vision and feel. Over-limit means that the side baffle 320 presses too much against the side wall of the bridge, which will cause the bridge to deform and affect the structural safety. Under-limit means that the distance between the side baffle 320 and the side wall of the bridge is too large, and longer bolts need to be replaced for connection, which will also reduce the stability of the connection.

[0043] In order to improve the smoothness of movement, the present embodiment optimizes the connection structure of the hinge rod 400, the elastic member 500 and the locking ball 600. Figure 5-6A mounting groove is provided on the side of the hinged rod 400 facing the locking ball 600, and the elastic member 500 is fixed in the mounting groove. Part of the structure of the locking ball 600 is placed in the mounting groove, while the portion exposed from the mounting groove abuts against the inner sidewall of the limiting groove 313 or the strip-shaped through hole 312. Based on the above solution, a stabilizing rod 700 can also be provided on the top plate of the U-shaped groove 311. The stabilizing rod 700 is located between the two sets of bottom supporting plates 310, and its two ends are respectively slidably inserted into the top plate of the U-shaped groove 311 to avoid interfering with the adjustment of the scissor arm assembly 200. On the one hand, the stabilizing rod 700 can limit the moving direction of the limit frame 300 during the adjustment of the scissor arm group 200, ensuring that the position correspondence between the two groups of limit frames 300 remains unchanged before and after adjusting the scissor arm group 200. On the other hand, there is a certain friction between the stabilizing rod 700 and the top plate of the U-shaped groove 311, which can limit the approach speed of the limit frame 300 and prevent the worker from exerting too much force and causing the second scissor arm 220 to slip off the bottom support plate 310.

[0044] How to use this bracket:

[0045] (1) According to the wiring design, use countersunk screws to install the flange seat 110 at the designated location on the building facade, and slide the T-shaped block 150 on the side of the support rib 120 from top to bottom and install it in the T-shaped bracket 112 on the flange seat 110;

[0046] (2) According to the wiring design, slide the slide 130 to adjust the distance between the slide 130 and the flange seat 110, that is, adjust the distance between the limit frame 300 and the flange seat 110, and use the locking member 140 to fix the slide 130;

[0047] (3) Stretch the scissor arm assembly 200 to increase the distance between the two groups of limit frames 300, place the bridge frame on the bottom support plate 310 of the limit frame 300, compress the scissor arm assembly 200 to reduce the distance between the two groups of limit frames 300, until the side baffle 320 abuts the bridge frame and the locking ball 600 falls into the corresponding limit groove 313, and use bolts to connect and fix the side baffle 320 and the bridge frame.

[0048] Compared with the prior art, the beneficial effects of the present invention are:

[0049] (1) The connection configuration between the slide 130 and the support rib 120, and the connection configuration between the slide 130 and the scissor arm assembly 200, is conducive to accurately controlling the installation position of the bridge according to the wiring design, making the layout more accurate and improving the construction quality;

[0050] (2) The configuration of the scissor arm group 200 is conducive to adjusting the distance between the two groups of limit frames 300 according to the specifications of the bridge frame. This makes the bracket suitable for bridge frames of various sizes. During construction, there is no need to prefabricate redundant brackets of various models and sizes, thus avoiding material waste.

[0051] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
