Description

Technical Field

[0001] The utility model relates to the technical field of display rack structures, in particular to a folding display rack with a bare rod locking structure, which is used for fast fixing of flat-lying carpet samples. Background Art

[0002] Exhibition racks are usually customized according to the characteristics and placement habits of the exhibited samples. Existing samples such as carpets are usually displayed in a hanging or lying manner. When samples are displayed lying down, they are usually stacked in multiple layers. The existing technology is to stack them on a platform. Without enclosures, it is easy to become messy when multiple people browse through them. Some have added tray enclosures, but it is inevitable that they will be turned over and fall, which needs to be improved. Utility Model Content

[0003] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, a folding display frame with a bare rod locking structure is provided.

[0004] The technical solution adopted by the utility model to solve the technical problem is: a folding display frame with a bare rod locking structure, comprising a display frame base, the display frame base is movably connected with a supporting sheet metal through a hinge, and the supporting sheet metal is supported and connected to the display frame base through a supporting tie rod;

[0005] A display stand platform for placing samples of flat-lying carpets is installed on the upper end of the supporting sheet metal, a pressure strip for pressing the samples is arranged on the display stand platform, a through hole is provided on the pressure strip, and a hole groove cooperating with the through hole is provided at the bottom of the display stand platform, and the pressure strip, the samples and the hole groove are fixed by setting a light rod locking mechanism.

[0006] By adopting the above technical solution, the display of flat-lying carpet samples can be quickly locked and fixed and quickly replaced without the need for other complex fastening structures, bolt connections and bayonet connections.

[0007] Furthermore, the bare rod locking mechanism of the utility model comprises a metal rod and a locker sleeved on the metal rod, the locker comprises a base, a metal ring with a conical inner cavity is arranged in the base, a handle piece is connected in the locker through a spring and a plastic ring, one end of the handle piece is inserted into the conical inner cavity of the metal ring, and the other end is exposed outside the base;

[0008] A steel ball group is arranged on the outer circumferential surface of the end portion of the handle member located in the conical inner cavity.

[0009] Furthermore, the steel ball set described in the utility model includes steel balls that are evenly arranged in a circumference in the end groove of the handle piece.

[0010] By adopting the above technical solution, the steel ball is inside the left metal ring, and the inside of the metal ring is conical, which squeezes the steel ball toward the center and compresses the metal rod; when the metal rod moves, it pushes the steel ball to rotate and move with it, but because the conical inner cavity inside the metal ring is larger on one side and smaller on the other side, the metal rod can only be pushed to one side, and combined with the spring structure, manual unlocking can be achieved.

[0011] Furthermore, the upper end of the support rod of the utility model is rotatably connected to the support sheet metal, and the lower end of the support rod is provided with a locking hook to hook the preset screws on the frame of the display stand base to achieve support.

[0012] The beneficial effects of the utility model are as follows: the folding display frame with a bare rod locking structure of the utility model has the following advantages over the prior art:

[0013] 1. The flat-lying carpet sample adopts a bare rod locking structure for quick installation and removal. It does not need to install other complicated locking devices or fix with bolts and pins, making the operation simpler.

[0014] 2. With a foldable base, the base and the display stand support sheet metal can be closed and unfolded through hinges. The support structure is easy to operate during use and saves assembly time. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment 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.

[0022] like Figure 1 to Figure 3 A folding display stand with a bare rod locking structure shown in the figure comprises a display stand base 1, a support sheet metal 3 is movably connected to the display stand base 1 via a hinge 2, and the support sheet metal 3 is supported and connected to the display stand base 1 via a support tie rod 4;

[0023] A display stand platform 6 for placing a sample 5 of a flat-lying carpet is installed on the upper end of the supporting sheet metal 3. A pressure strip 7 for pressing the sample 5 is provided on the display stand platform 6. A through hole 8 is provided on the pressure strip 7. A hole groove matching the through hole 8 is provided at the bottom of the display stand platform 6. The pressure strip 7, the sample 5 and the hole groove are fixed by setting a light rod locking mechanism.

[0024] The bare rod locking mechanism includes a metal rod 9 and a locker 10 sleeved on the metal rod 9, the locker 10 includes a base 11, a metal ring 12 with a conical inner cavity is arranged in the base 11, a handle 15 is connected to the locker 10 through a spring 13 and a plastic ring 14, one end of the handle 15 is inserted into the conical inner cavity of the metal ring 12, and the other end is exposed outside the base 11; a steel ball group is arranged on the outer circumferential surface of the end of the handle 15 located in the conical inner cavity. The steel ball group includes steel balls 16 uniformly arranged in the groove at the end of the handle 15 according to the circumference.

[0025] The upper end of the support rod 4 is rotatably connected to the support sheet metal 3 , and the lower end of the support rod 4 is provided with a locking hook 17 to hook the preset screw 18 on the frame of the display stand base 1 to achieve support.

[0026] Working principle: Figure 4 As shown:

[0027] Static state (handle not pulled out)

[0028] The steel ball is inside the metal ring on the left. The inside of the metal ring is conical. Press the steel ball toward the center and compress the metal rod;

[0029] The metal rod pushes from left to right: the steel ball rotates counterclockwise, and the metal rod can be pushed because the inner cone of the metal ring is larger on the left and smaller on the right;

[0030] The metal rod is pushed from right to left: the steel ball rotates clockwise. Since the left side of the cone inside the metal ring is larger and the right side is smaller, the metal rod cannot be pushed. In this way, the metal rod can be pushed in one direction and fixed in the opposite direction.

[0031] Stretched state (handle pulled out)

[0032] Pull the handle to the right, and pull the steel ball to the right together, to separate from the metal ring, so that the steel ball no longer presses the metal rod; in this state, the metal rod can be pushed in any direction;

[0033] The display of the flat-lying carpet samples can be quickly locked and fixed and quickly replaced without the need for other complex fastening structures, bolt connections and bayonet connections.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
