Description

Technical Field

[0001] The utility model belongs to the technical field of power auxiliary facilities, and in particular relates to a pre-buried telescopic fence pole. Background Art

[0002] Pre-buried telescopic fence poles are auxiliary power facilities, mainly used in power-related areas such as substations. Before use, they are buried in the designated area. When in use, the telescopic poles are extended and the warning tape is installed to provide a warning and protection function.

[0003] When the existing fence poles are stretched out or retracted, they mainly rely on friction, and there is no clamping structure between them. During a long construction period, the stretched fence poles can easily fall and retract due to insufficient friction between them, thereby affecting the normal use of the fence poles. Utility Model Content

[0004] The utility model provides a pre-buried telescopic fence rod to solve the above technical problems.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A pre-buried telescopic fence pole comprises an underground pipe, which can accommodate N telescopic rods connected in sequence telescopically in the underground pipe, where N is an integer greater than or equal to N; when in use, the telescopic rod and the underground pipe, as well as the adjacent telescopic rods, can be fixed by a clamping piece and a card slot; it also includes: an anti-retraction component, including: a reset button, which is arranged at the top of the Nth telescopic rod; a first push rod, which can be slidably arranged in the Nth telescopic rod, and the top is connected to the reset button; and / or a second push rod, which is arranged at the outer bottom of the telescopic rod; a spring sheet, one end of which is arranged on the inner side of the telescopic rod, and the other end is connected to the clamping piece; the number of the spring sheets is consistent with the number of the telescopic rods; when the reset button is pressed down, the first push rod and / or the second push rod can be connected to the spring sheet.

[0007] Furthermore, the anti-retraction assembly further comprises: a connecting rod, both ends of which are respectively connected to the reset button and the first push rod; a portion of the connecting rod's length can slide within the Nth telescopic rod.

[0008] Furthermore, two ends of the spring are respectively arranged on two sides of the telescopic rod.

[0009] Furthermore, the fence pole also includes: a mounting plate, which is a ring-shaped structure and is arranged on the top of the buried pipe; a protective member, which is hinged on the mounting plate; when not in use, the protective member can be flipped over and close the telescopic rod.

[0010] Furthermore, a vertical projection of the protective member is outside the inner ring of the mounting plate.

[0011] Furthermore, the fence pole also includes: an upper hook, which is arranged at the top end of the telescopic rod described in Article N; a lower hook, which is arranged on the mounting plate; the reset button is arranged through the upper hook; the lower hook is provided with a through storage groove, and the telescopic rod is located in the storage groove.

[0012] Furthermore, the vertical projections of the upper hook and the lower hook are within the vertical projection range of the protective element.

[0013] Furthermore, the fence pole also includes: a sealing ring, which is arranged between the mounting plate and the lower hook.

[0014] Furthermore, the buried pipe, the telescopic rod, the mounting plate, the protective member, the upper hook, and the lower hook are made of metal materials.

[0015] Furthermore, the buried pipe, the mounting plate, and the protective member are made of rust-proof metal materials; the telescopic rod, the upper hook, and the lower hook are made of aluminum alloy materials.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When the telescopic rod of the present application is stretched to a suitable position, the clamping piece will be stuck in the slot, thereby achieving fixation; and the anti-retraction component provided can only retract the telescopic rod when the reset button is pressed, causing the first push rod and / or the second push rod to move downward to squeeze the spring sheet to cause it to deform. Since one end of the spring sheet is fixed, the non-fixed end is squeezed and deformed, thereby causing the clamping piece to disengage from the slot; and since the spring sheet has an elastic effect, when the reset button is not pressed, the clamping piece will be more firmly stuck in the slot due to the elastic force of the spring sheet, thereby avoiding the non-human retraction of the telescopic rod and affecting the normal use of the fence rod.

[0018] 2. When not in use, the telescopic rod is fully retracted and placed in the buried tube. At this time, the protective piece can be flipped over to cover the mounting plate, thereby enclosing the telescopic rod in the protective piece. This prevents the fence rod from being damaged by a lawn mower or a maintenance vehicle from entering due to the lack of the protective piece, thus ensuring normal use.

[0019] 3. Both the upper hook and the lower hook are equipped with hooks for hanging the warning tape when in use; after use, the warning tape can be removed from the hook, thereby improving the convenience of use.

[0020] 4. The sealing ring can seal the gap between the lower hook and the mounting plate. Combined with the use of protective parts, it can prevent water, sand and other debris from entering the buried pipe and affecting the normal use of the fence pole. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] In order to facilitate a better understanding of the present invention, the following examples are used to illustrate the present invention in conjunction with the accompanying drawings. These examples belong to the protection scope of the present invention, but do not limit the protection scope of the present invention.

[0031] Example 1

[0032] A pre-buried telescopic fence pole, such as Figure 1-Figure 7As shown, it includes a buried pipe 1, N telescopic rods 2 that can be accommodated in the buried pipe 1 and are telescopically connected in sequence, where N is an integer greater than or equal to 1; when in use, the telescopic rod 2 and the buried pipe 1, as well as the adjacent telescopic rods 2, can be fixed by matching the clamping piece 21 with the clamping slot 22; it also includes: an anti-retraction component 3, including: a reset button 31, provided at the top of the Nth telescopic rod 2; a first push rod 32, slidably provided in the Nth telescopic rod 2, and the top is connected to the reset button 31; and / or a second push rod 33, provided at the outer bottom of the telescopic rod 2; a spring piece 34, one end of which is provided on the inner side of the telescopic rod 2, and the other end is connected to the clamping piece 21; the number of spring pieces 34 is consistent with the number of telescopic rods; when the reset button 31 is pressed down, the first push rod 32 and / or the second push rod 33 can be connected to the spring piece 34.

[0033] There is a cavity inside the buried pipe, and a telescopic rod is connected to the cavity. When not in use, the telescopic rod retracts and can be returned to the cavity. The length of each telescopic rod should be close to the length of the buried pipe to avoid a large difference in length between the two. When not in use, the length of the telescopic rod protruding from the buried pipe is too high, which affects normal use.

[0034] The buried pipe and the connected telescopic rod can be fixed by a clamping piece and a clamping groove. The clamping piece can be a marble, which is fixed by being clamped into the clamping groove. Since the buried pipe is buried underground, in order to prevent water, mud, sand and other debris from entering the cavity of the buried pipe through the clamping groove, the clamping groove is only arranged on the inner side of the buried pipe cavity and cannot penetrate the side wall of the buried pipe.

[0035] A spring is set in the reset button. When it is subjected to external force, the reset button presses down to squeeze the spring; when the external force is released, the reset button can be restored to its original position.

[0036] The clamping piece can be a marble, and the clamping groove matches the marble, so as to achieve clamping and fixing during stretching.

[0037] The telescopic rods can be provided with a plurality of them, such as 2, 3 or 4, and the telescopic rods are telescopically connected to each other; when in use, the telescopic rods can be partially or fully extended according to the actual length used.

[0038] The spring piece has elasticity and is made of existing elastic material; one end of the spring piece connected to the clamping piece is not fixed on the inner wall of the buried pipe or the telescopic rod; Figure 1 As shown, the spring piece is arranged obliquely, with folded edges at both ends, which are used to fix and connect the clamping parts respectively.

[0039] Instructions for use: Select the appropriate number of fence poles according to the size of the area of use and distribute them to the appropriate positions; then dig a hole and install the buried pipe, which can be fixed with concrete backfill; when in use, stretch out the appropriate number of telescopic rods according to actual needs (there is no need to press the reset button when the telescopic rod is extended), and after the telescopic rod and the buried pipe, and the adjacent telescopic rods are stretched to the appropriate position, the clamping parts and the slots are matched, and each group of clamping parts can be clamped into the corresponding slot to achieve a fixing effect between the telescopic rod and the buried pipe, and the adjacent telescopic rods; after use, press the reset button to move the first push rod and / or the second push rod downward to squeeze the spring piece to deform it. Since one end of the spring piece is fixed and the end connected to the clamping part is not fixed, the spring piece is deformed under force and drives the clamping part out of the slot, causing the telescopic rod to retract.

[0040] During use, due to the elastic force of the spring sheet, when the telescopic rod retracts, it is necessary to press the reset button to squeeze the spring sheet so that the clamping part disengages from the slot, and the corresponding telescopic rod can retract, avoiding the existing telescopic rod retracting due to insufficient friction and other reasons, affecting normal use.

[0041] Example 2

[0042] like Figure 5-Figure 6 As shown, the anti-retraction assembly 3 further includes: a connecting rod 35 , both ends of which are connected to the reset button 31 and the first push rod 32 respectively; a portion of the length of the connecting rod 35 can slide within the Nth telescopic rod 2 .

[0043] like Figure 5-Figure 6 As shown, the two ends of the spring piece 34 are respectively arranged on both sides of the telescopic rod 2 or the buried pipe 1.

[0044] The connecting rod can partially extend into the inner cavity of the Nth telescopic rod and slide up and down. When in use, the reset button is pressed down, the connecting rod is forced to move downward into the inner cavity of the telescopic rod and push the first push rod forward to squeeze the spring piece, so that the clamping piece disengages from the slot and the telescopic rod retracts.

[0045] During the pressing process, when the connecting rod part enters the inner cavity of the Nth telescopic rod, it retracts into the inner cavity of the N-1th telescopic rod; at this time, continue to press the reset button. Since the connecting rod can no longer enter the Nth telescopic rod, it will continue to maintain the squeezing effect on it, so that the second push rod moves forward and squeezes the spring piece, so that the clamping piece disengages from the slot. At this time, the N-1th telescopic rod retracts into the N-2th telescopic rod; in this way, all the telescopic rods are directly retracted.

[0046] Example 3

[0047] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 7As shown, the fence pole also includes: a mounting plate 4, which is a ring-shaped structure and is arranged on the top of the buried pipe 1; a protective member 5, which is hinged on the mounting plate 4; when not in use, the protective member 5 can be flipped over and close the telescopic rod 2.

[0048] like Figure 7 As shown, the vertical projection of the protective element 5 is outside the inner ring of the mounting plate 4 .

[0049] Since the area where the fence poles are set up will be planted with grass and greenery, when the grass grows long, it may cover the fence poles. When using a lawn mower to mow the grass, it is easy for the lawn mower to damage the fence poles. Or when construction and maintenance are carried out, it is necessary to drive in. If you are not careful, the vehicle may press on the fence poles and cause damage. Therefore, a mounting plate and a protective part are set up. When not in use, the protective part can be flipped over to cover the mounting plate, thereby enclosing the telescopic rod in the protective part, avoiding damage to the fence poles by lawn mowers or maintenance vehicles, and playing a protective role.

[0050] Example 4

[0051] like Figures 1-6 As shown, the fence rod also includes: an upper hook 6, which is arranged at the top of the Nth telescopic rod 2; a lower hook 7, which is arranged on the mounting plate 4; a reset button 31 is arranged through the upper hook 6; the lower hook 7 is provided with a through storage groove 71, and the telescopic rod 2 is in the storage groove 71.

[0052] like Figure 4 ,like Figure 7 As shown, the vertical projections of the upper hook 6 and the lower hook 7 are within the vertical projection range of the protective element 5 .

[0053] The fence pole also includes a sealing ring 8 , which is arranged between the mounting plate 4 and the lower hook 7 .

[0054] The upper hook and the lower hook are both provided with hooks on their sides. When in use, the hooks can hang the warning tape; after use, the warning tape can be removed from the hooks, which improves the convenience of operation.

[0055] Example 5

[0056] like Figure 1-Figure 7 As shown, the buried pipe 1, the telescopic rod 2, the mounting plate 4, the protective member 5, the upper hook 6, and the lower hook 7 are made of metal materials.

[0057] like Figure 1-Figure 7 As shown, the buried pipe 1, the mounting plate 4, and the protective member 5 are made of rust-proof metal materials; the telescopic rod 2, the upper hook 6, and the lower hook 7 are made of aluminum alloy materials.

[0058] Since the buried pipe is buried underground, and the mounting plate and protective parts are on the ground, they need to prevent damage by lawn mowers or maintenance vehicles. Therefore, they must have a certain strength and should be prevented from rusting to extend their service life. Therefore, they can be made of materials such as stainless steel; the telescopic rod, upper hook, and lower hook are in the buried pipe when not in use. They can be made of lightweight aluminum alloy, which is more resistant to aging than plastic and can extend its service life.

Moreover, the terms "include," "comprise," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or device. Without further limitation, the phrase "comprising an element defined by..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
