Description

Technical Field

[0001] The utility model relates to the technical field of cable trays, in particular to a tray-type cable tray. Background Art

[0002] Cable trays are divided into trough-type, tray-type, ladder-type, grid-type and other structures, and are composed of brackets, bracket arms and installation accessories, etc. The cable trays in buildings can be erected independently or laid on various building and pipe gallery brackets. All parts need to be galvanized. The cable trays installed outdoors are exposed to the elements.

[0003] There is a prior tray-type cable tray (its authorization announcement number is: CN219371933U): through the mutual cooperation between the upper limit block, the connecting rod, the movable piece, the first spring and the fixed block, it is convenient to better limit and fix the cable above, avoiding the phenomenon that the cables inside the cable tray are scattered, and achieving a better cable neatness effect.

[0004] However, there are some deficiencies in the actual use of this kind of tray-type cable tray: through the upper limit block, multiple cables can be clamped and limited and fixed at the same time, but this method is not convenient for adjusting a single cable. When the corresponding cable needs to be removed, the other cables will be scattered due to lack of limit fixation, and its practicability is relatively low; Therefore, we have proposed the present utility model to solve the above problems. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the present utility model provides a tray-type cable tray to solve the above problems.

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

[0007] A tray-type cable tray includes a lower cable tray and an upper cable tray. Slots are opened on the lower cable tray, and the upper cable tray is inserted into the slots of the lower cable tray. A plurality of bases are respectively fixedly installed on the bottom inner wall of the lower cable tray. Two arc-shaped grooves are respectively opened on the top sides of the bases. Four connecting plates are respectively fixedly installed on both side walls of each base. The same wire clamping wheel is fixedly installed between the corresponding four connecting plates. A plurality of wire clamping grooves are respectively opened on the wire clamping wheel. A wire sleeving mechanism for the wire clamping wheel is arranged in the arc-shaped groove. A plurality of downward pressing and clamping mechanisms are respectively arranged on the top inner wall of the upper cable tray.

[0008] Preferably, the number of wire clamping wheels on the base is two. The two wire clamping wheels are respectively located in the arc-shaped grooves corresponding to the top side of the base. A gap is arranged between the wire clamping wheel and the arc-shaped groove.

[0009] Preferably, the wire sleeving mechanism includes a limiting strip, a wire sleeving cylinder and a wire outlet. Two limiting strips are fixedly installed on the inner wall of the arc-shaped groove respectively. The same wire sleeving cylinder is rotatably installed on the two limiting strips. A wire outlet is formed in the wire sleeving cylinder. When the wire outlet on the wire sleeving cylinder communicates with the corresponding wire clamping groove on the wire clamping wheel at the place where the cable is to be taken out, it is convenient to take out the cable in the corresponding wire clamping groove on the wire clamping wheel at this time.

[0010] Preferably, the wire sleeving cylinder is rotatably sleeved on the outside of the wire clamping wheel, and the wire sleeving cylinder is rotatably installed in the gap between the wire clamping wheel and the arc-shaped groove. By rotatably sleeving the wire sleeving cylinder on the outside of the wire clamping wheel, the cable clamped in the wire clamping wheel is limited and fixed.

[0011] Preferably, the downward pressing and clamping mechanism includes a round sleeve, a convex head connecting rod, a downward pressing limiting plate and a spring. Two round sleeves are fixedly installed on the inner wall of the top side of the upper bridge frame respectively. The convex head ends of the convex head connecting rods are movably installed in the two round sleeves respectively. The other ends of the two convex head connecting rods penetrate outside the corresponding round sleeves and are fixedly installed with the same downward pressing limiting plate. The downward pressing limiting plate clamps on the two wire sleeving cylinders. Springs are fixedly installed on the bottom sides of the convex head ends of the two convex head connecting rods respectively. The other ends of the two springs are fixedly installed on the inner wall of the bottom side of the corresponding round sleeve. Under the elastic force of the two groups of springs, the downward pressing limiting plate presses and clamps on the two wire sleeving cylinders, reducing the occurrence of rotation of the two wire sleeving cylinders.

[0012] Preferably, a plurality of threaded holes are formed in both side walls of the upper bridge frame. Bolts are arranged on one side of the plurality of threaded holes respectively. One ends of the plurality of bolts penetrate through the lower bridge frame and are threadedly installed in the corresponding threaded holes. By threading the plurality of bolts through the lower bridge frame and threadedly installing them in the corresponding threaded holes, the fixed installation between the lower bridge frame and the upper bridge frame is realized.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] For this tray-type cable bridge, the cable clamped in multiple wire clamping grooves on the wire clamping wheel is limited and fixed by the wire sleeving cylinder rotatably sleeved on the outside of the wire clamping wheel. When the corresponding cable needs to be taken out, by rotating and adjusting the wire sleeving cylinder, the wire outlet on the wire sleeving cylinder communicates with the corresponding wire clamping groove on the wire clamping wheel at the place where the cable is to be taken out. At this time, it is convenient to take out the cable in the corresponding wire clamping groove on the wire clamping wheel. At the same time, the wire sleeving cylinder limits and fixes the cables clamped in the other wire clamping grooves, avoiding the scattering of the other cables when the corresponding cable is taken out, and improving the practicability of the tray-type cable bridge.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0022] Refer to Figures 1-5 , a tray type cable bridge frame, including a lower bridge frame 1 and an upper bridge frame 2. A slot 3 is opened on the lower bridge frame 1, and the upper bridge frame 2 is inserted into the slot 3 of the lower bridge frame 1. A plurality of bases 4 are respectively fixedly installed on the bottom inner wall of the lower bridge frame 1. Two arc grooves 5 are respectively opened on the top side of the base 4. Four connecting plates 6 are fixedly installed on both side walls of the base 4. The same wire clamping wheel 7 is fixedly installed between the corresponding four connecting plates 6. A plurality of wire clamping grooves 8 are respectively opened on the wire clamping wheel 7. A wire sleeving mechanism for the wire clamping wheel 7 is arranged in the arc groove 5. A plurality of downward pressure clamping mechanisms are respectively arranged on the top inner wall of the upper bridge frame 2.

[0023] Furthermore, the number of wire clamping wheels 7 on the base 4 is set to two. The two wire clamping wheels 7 are respectively located in the corresponding arc grooves 5 on the top side of the base 4, and there is a gap between the wire clamping wheel 7 and the arc groove 5.

[0024] Specifically, the wire sheathing mechanism includes a limit strip 9, a wire sheathing cylinder 10, and a wire outlet 11. Two limit strips 9 are fixedly installed on the inner wall of the arc-shaped groove 5 respectively. The same wire sheathing cylinder 10 is rotatably installed on the two limit strips 9, and a wire outlet 11 is formed in the wire sheathing cylinder 10. When the wire outlet 11 on the wire sheathing cylinder 10 communicates with the corresponding wire clamping groove 8 on the wire clamping wheel 7 at the position where the cable is to be taken out, it is convenient to take out the cable in the corresponding wire clamping groove 8 on the wire clamping wheel 7 at this time.

[0025] Specifically, the wire sheathing cylinder 10 is rotatably sleeved on the outside of the wire clamping wheel 7, and the wire sheathing cylinder 10 is rotatably installed in the gap between the wire clamping wheel 7 and the arc-shaped groove 5. By rotatably sleeving the wire sheathing cylinder 10 on the outside of the wire clamping wheel 7, the cable clamped in the wire clamping wheel 7 is limited and fixed.

[0026] Specifically, the downward pressing and clamping mechanism includes a round sleeve 12, a convex head connecting rod 13, a downward pressing limit plate 14, and a spring 15. Two round sleeves 12 are fixedly installed on the inner wall of the top side of the upper bridge frame 2 respectively. The convex head ends of the two convex head connecting rods 13 are movably installed in the two round sleeves 12 respectively. The other ends of the two convex head connecting rods 13 penetrate outside the corresponding round sleeves 12 and are fixedly installed with the same downward pressing limit plate 14. The downward pressing limit plate 14 clamps on the two wire sheathing cylinders 10. Springs 15 are fixedly installed on the bottom sides of the convex head ends of the two convex head connecting rods 13 respectively. The other ends of the two springs 15 are fixedly installed on the inner wall of the bottom side of the corresponding round sleeve 12 respectively. Under the elastic force of the two groups of springs 15, the downward pressing limit plate 14 presses and clamps on the two wire sheathing cylinders 10, reducing the occurrence of rotation of the two wire sheathing cylinders 10.

[0027] Furthermore, a plurality of threaded holes 16 are formed in both side walls of the upper bridge frame 2. Bolts 17 are arranged on one side of the plurality of threaded holes 16. One ends of the plurality of bolts 17 penetrate through the lower bridge frame 1 and are threadedly installed in the corresponding threaded holes 16. By penetrating the lower bridge frame 1 with the plurality of bolts 17 and threadedly installing them in the corresponding threaded holes 16, the fixed installation between the lower bridge frame 1 and the upper bridge frame 2 is realized.

[0028] In use: When it is necessary to take out the corresponding cables in the lower bridge frame 1 and the upper bridge frame 2, by sequentially removing a plurality of bolts 17, and then moving the upper bridge frame 2 out of the slot 3 of the lower bridge frame 1. At this time, the lower pressure limiting plate 14 clamped on the two corresponding wire sheathing cylinders 10 is separated from the two wire sheathing cylinders 10. Then, rotate and adjust the corresponding wire sheathing cylinders 10 in sequence to make the wire outlet 11 on the wire sheathing cylinder 10 communicate with the corresponding wire clamping groove 8 on the wire clamping wheel 7 at the place where the cable is to be taken out. At this time, it is convenient to take out the cable in the corresponding wire clamping groove 8 on the wire clamping wheel 7. At the same time, the wire sheathing cylinder 10 limits and fixes the cables clamped in the other wire clamping grooves 8 to prevent the other cables from becoming scattered when the corresponding cable is taken out; In this case, for the tray-type cable bridge, the cables clamped in the multiple wire clamping grooves 8 on the wire clamping wheel 7 are limited and fixed by rotating the wire sheathing cylinder 10 sleeved outside the wire clamping wheel 7. When it is necessary to take out the corresponding cable, by rotating and adjusting the wire sheathing cylinder 10 to make the wire outlet 11 on the wire sheathing cylinder 10 communicate with the corresponding wire clamping groove 8 on the wire clamping wheel 7 at the place where the cable is to be taken out, at this time, it is convenient to take out the cable in the corresponding wire clamping groove 8 on the wire clamping wheel 7.
