Description

Technical Field

[0001] The utility model relates to the technical field of breeding isolation fences, in particular to a breeding isolation fence. Background Art

[0002] The livestock and poultry breeding industry is an important part of China's agriculture. The pig breeding industry, as one of the earlier developed and larger-scale industries in livestock breeding, has played an active role in the process of China's agricultural development. With the continuous development of the economy and the continuous improvement of people's living standards, the market demand for pork is also steadily increasing.

[0003] When raising pigs, isolation fences are needed. Among them, most of the fixing of the isolation fence doors uses snap locks for locking. However, in actual use, the position of this accessory is often licked by pigs. The traditional snap lock has no limit structure for the lock tongue, so the situation where the lock tongue is licked up will occur. At this time, if the pig pushes forward slightly against the front door, it can run out of the pen. The snap lock has certain safety hazards for fixing the isolation fence door. Based on this, a breeding isolation fence is provided. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a breeding isolation fence to solve the problems in the above background.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A breeding isolation fence, including an isolation fence composed of side guardrails, columns, and guardrail doors. The columns are welded and fixed to the front end of the side guardrails. The guardrail doors are distributed at the front ends of the two side guardrails to block the space between the two side guardrails. A rotating support seat and a snap lock assembly are welded and fixed to the outer ends of the columns. There are two rotating support seats distributed up and down with the snap lock assembly as the center. Rotating hooks and locking hooks are welded and fixed to both sides of the outer wall of the guardrail door respectively. The guardrail door is rotatably connected to the rotating support seat through the rotating hook, and the guardrail door is clamped with the snap lock assembly through the locking hook. The snap lock assembly includes a self-locking unit and a linkage unlocking unit;

[0006] When the locking hook collides with the self-locking unit, the self-locking function is realized to fix the closed state of the guardrail door;

[0007] The linkage unlocking unit is used to release the locking of the self-locking unit on the locking hook by pressing.

[0008] As a further scheme of the utility model: The self-locking unit includes an L-shaped fixed seat, a U-shaped fixed block, a lock tongue, a vertical notch, a fixing bolt, and a right-angle card slot;

[0009] The L-shaped fixing base is welded and fixed to the outer wall end face of the column. The U-shaped fixing block is fixed to one end of the vertical part of the L-shaped fixing base away from the column, and a collision locking groove is formed between the bottom of the U-shaped fixing block and the horizontal part of the L-shaped fixing base.

[0010] The locking tongue is vertically slidably connected to the inside of the U-shaped fixing block, and the bottom of the locking tongue protrudes from the inside of the collision locking groove. The vertical slot is opened on one side of the outer wall of the locking tongue and penetrates through the other side of the locking tongue. The fixing bolt sequentially penetrates through the U-shaped fixing block and the vertical slot and is fixed to the outside of the U-shaped fixing block by a nut. The sliding connection between the fixing bolt and the vertical slot is used to provide guidance and limit for the up and down movement of the locking tongue.

[0011] The right-angle card slot is formed at the bottom of one end of the locking tongue close to the vertical part of the L-shaped fixing base. The other end bottom of the locking tongue is in an arc surface structure. When the locking hook rotates into the inside of the collision locking groove and contacts the arc surface at the bottom of the locking tongue, it squeezes the locking tongue to move up. When the locking hook enters the inside of the collision locking groove, the locking tongue moves down and is clamped to the outside of the locking hook through the right-angle card slot to achieve the locking of the locking hook.

[0012] As a further scheme of the present invention: The linkage unlocking unit includes a pressing block, a U-shaped pressing block, an inclined guide groove, and a W-shaped elastic sheet.

[0013] The pressing blocks are symmetrically fixed to the tops of both sides of the outer wall of the locking tongue. The U-shaped pressing block is sleeved on the outside of the locking tongue, and the inclined guide groove penetrates through both sides of the U-shaped pressing block. The pressing block is slidably connected to the inside of the inclined guide groove. When the locking tongue moves up, the pressing block can push the U-shaped pressing block to move horizontally by squeezing the U-shaped pressing block.

[0014] The W-shaped elastic sheet is installed inside the U-shaped pressing block, and one end of the W-shaped elastic sheet is fixedly connected to the inner wall end face of the U-shaped pressing block, and the other end is closely attached to the end face of the vertical part of the L-shaped fixing base, which is used to provide a thrust for the U-shaped pressing block.

[0016] As a further scheme of the present invention: The pressing and unlocking direction of the U-shaped pressing block faces the isolation area formed by the two side guardrails.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] By setting the U-shaped pressing block, the inclined guide groove and the extrusion block, it is necessary to press the U-shaped pressing block towards the column to unlock the latch assembly. When the breeding pigs lick the U-shaped pressing block during daily life, the force exerted on the U-shaped pressing block is upward or away from the column, that is, the pressing operation on the U-shaped pressing block cannot be realized, thus ensuring the stability of the closed state of the guardrail door.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 4, in the embodiment of the present utility model, a breeding isolation railing includes an isolation railing 1 composed of a side guardrail 101, a column 102, and a guardrail door 103. The column 102 is welded and fixed to the front end of the side guardrail 101. The guardrail doors 103 are distributed at the front ends of the two side guardrails 101 to block the space between the two side guardrails 101. A rotating support seat 2 and a collision lock assembly 3 are welded and fixed to the outer ends of the columns 102. There are two rotating support seats 2 distributed up and down with the collision lock assembly 3 as the center. Rotating hooks 104 and locking hooks 105 are welded and fixed to both sides of the outer wall of the guardrail door 103 respectively. The guardrail door 103 is rotatably connected to the rotating support seat 2 through the rotating hook 104, and the guardrail door 103 is clamped with the collision lock assembly 3 through the locking hook 105. The collision lock assembly 3 includes a self-locking unit and a linkage unlocking unit;

[0026] When the locking hook 105 collides with the self-locking unit, the self-locking function is realized to fix the closed state of the guardrail door 103. The linkage unlocking unit is used to release the locking of the self-locking unit on the locking hook 105 by pressing;

[0027] The self-locking unit includes an L-shaped fixing seat 301, a U-shaped fixing block 302, a locking tongue 304, a vertical notch 305, a fixing bolt 307, and a right-angle card slot 308;

[0028] The L-shaped fixing seat 301 is welded and fixed to the outer wall end face of the column 102. The U-shaped fixing block 302 is fixed to the end of the vertical part of the L-shaped fixing seat 301 away from the column 102, and a collision lock groove 303 is formed between the bottom of the U-shaped fixing block 302 and the horizontal part of the L-shaped fixing seat 301;

[0029] The locking tongue 304 is vertically slidably connected to the inside of the U-shaped fixing block 302, and the bottom of the locking tongue 304 protrudes from the inside of the collision lock groove 303. The vertical notch 305 is opened on one side of the outer wall of the locking tongue 304 and penetrates through the other side of the locking tongue 304. The fixing bolt 307 sequentially penetrates through the U-shaped fixing block 302 and the vertical notch 305 and is fixed to the outside of the U-shaped fixing block 302 through a nut. The sliding connection between the fixing bolt 307 and the vertical notch 305 is used to provide guidance and limit for the up and down movement of the locking tongue 304;

[0030] The right-angle card slot 308 is formed at the bottom of the end of the locking tongue 304 close to the vertical part of the L-shaped fixing seat 301. The other end bottom of the locking tongue 304 is in an arc surface structure. When the locking hook 105 rotates into the inside of the collision lock groove 303 and contacts the bottom arc surface of the locking tongue 304, the locking tongue 304 is squeezed to move up. When the locking hook 105 enters the inside of the collision lock groove 303, the locking tongue 304 moves down and is clamped to the outside of the locking hook 105 through the right-angle card slot 308 to realize the locking of the locking hook 105;

[0031] The linkage unlocking unit includes a pressing block 306, a U-shaped pressing block 309, an inclined guide groove 310, and a W-shaped elastic sheet 311;

[0032] The extrusion blocks 306 are symmetrically fixed to the tops of both sides of the outer wall of the locking tongue 304. The U-shaped pressing block 309 is sleeved on the outside of the locking tongue 304, and the inclined guide groove 310 penetrates through both sides of the U-shaped pressing block 309. The extrusion blocks 306 are slidably connected to the inside of the inclined guide groove 310. When the locking tongue 304 moves upward, the extrusion of the U-shaped pressing block 309 by the extrusion blocks 306 can push the U-shaped pressing block 309 to move horizontally; The W-shaped elastic piece 311 is installed inside the U-shaped pressing block 309, and one end of the W-shaped elastic piece 311 is fixedly connected to the inner wall end face of the U-shaped pressing block 309, and the other end is closely attached to the vertical part end face of the L-shaped fixing seat 301, which is used to provide a thrust force for the U-shaped pressing block 309;

[0033] The pressing and unlocking direction of the U-shaped pressing block 309 faces the isolation area formed by the two side guardrails 101.

[0034] In this embodiment: When the guardrail door 103 is closed, the guardrail door 103 will rotate with the rotating support base 2 as the base. The guardrail door 103 will drive the locking hook 105 to approach the collision lock assembly 3. When the locking hook 105 enters the inside of the collision lock groove 303 and contacts the bottom arc surface of the locking tongue 304, an upward thrust force will be given to the locking tongue 304, so that the locking tongue 304 moves upward based on the fixing bolt 307. The locking tongue 304 squeezes the inclined guide groove 310 through the extrusion blocks 306, so that the U-shaped pressing block 309 moves towards the column 102 and squeezes the W-shaped elastic piece 311 to further deform;

[0035] As the locking tongue 304 moves upward, it will not block the continuous advancement of the locking hook 105. When the locking hook 105 completely enters the inside of the collision lock groove 302, the locking tongue 304 loses the extrusion force. At this time, the locking tongue 304 will move downward and reset under the action of its own gravity and the elastic force of the W-shaped elastic piece 311 (it should be noted that: at this time, the U-shaped pressing block 309 moves synchronously and resets). The bottom right-angle card slot 308 of the locking tongue 304 will be stuck outside the locking hook 105. Due to the straight surface structure of the right-angle card slot 308, if the locking hook 105 wants to move outward and squeeze the straight surface of the right-angle card slot 308, it cannot apply an upward extrusion force to the locking tongue 304. In this way, the locking hook 105 is limited and locked in the collision lock groove 303, that is, the fixed state of the closed guardrail door 103 is realized;

[0036] If you want to open the guardrail door 103, just manually press the U-shaped pressing block 309 to make it move towards the column 102. The U-shaped pressing block 309 squeezes the extrusion blocks 306 through the inclined guide groove 310, so that the extrusion blocks 306 move upward and drive the locking tongue 304 to move upward synchronously. In this way, the limit on the locking hook 1105 is released. At this time, rotate and open the guardrail door 103 synchronously;

[0037] Through the cooperation of the above-mentioned multiple parts, unlocking the latch assembly 3 requires pressing the U-shaped pressing block 309 towards the column 102. When the breeding pigs lick the U-shaped pressing block 309 during daily activities, the force exerted on the U-shaped pressing block 309 is upward or away from the column 102, that is, the pressing operation on the U-shaped pressing block 309 cannot be achieved, thus ensuring the stability of the closed state of the guardrail door 103.

[0038] Please refer particularly to Figure 4 , a through groove 312 is provided at one end of the bottom of the U-shaped pressing block 309, and the through groove 312 is aligned with the upward movement area of the lock tongue 304.

[0039] In this embodiment: Through this structure, the horizontal movement of the U-shaped pressing block 309 and the upward movement of the lock tongue 304 will not interfere, ensuring the normal operation of the latch assembly 3.

[0040] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
